W25Q128JVSIQ is a 128 Mb serial NOR Flash memory from Winbond in an 8-pin SOIC package, for code and data storage in embedded systems — firmware images, configuration tables and data logging. Its advantage is the standard SPI interface and JEDEC-compatible footprint, which keeps the memory subsystem interchangeable across controller platforms and simplifies second-sourcing. Selection advice: flash holds your firmware, so this is the wrong part to buy on price alone — confirm the exact 128 Mb density code and require date-code traceability, because wrong-density or remarked flash causes field failures that are expensive to recall. The SIQ suffix pins the SOIC-8 package; state whether you need blank or pre-programmed devices in your RFQ. We reconfirm manufacturer, density code, lot and traceability against the offered lot before quotation and reply within 24 hours.

W25Q64JVSSIQ is a 64 Mb serial NOR Flash memory from Winbond in an 8-pin SOIC package, for firmware and data storage in embedded systems. Its advantage is the standard SPI interface and JEDEC-compatible footprint shared across the W25Q family, which keeps the memory subsystem portable across controller platforms. Selection advice: match the 64 Mb density code exactly — firmware images are built for a specific flash size, and a wrong-density substitute causes boot failures. As with all flash holding firmware, buy on traceability rather than price: require lot and date codes, and state in your RFQ whether you need blank or pre-programmed devices. We reconfirm manufacturer, density code, lot and traceability against the offered lot before quotation and reply within 24 hours.

W25Q32JVSSIQ is a Winbond 32 Mb serial NOR Flash memory in SOIC-8, tube — for firmware images, boot code and configuration storage in embedded systems. Quad-SPI reads up to 133 MHz with 2.7 V to 3.6 V operation across the −40 °C to +85 °C industrial range is the selection point: fast execute-in-place reads for MCUs that boot directly from flash. Selection advice: match the 32 Mb density code exactly — firmware images are built for a specific flash size, and a wrong-density substitute causes boot failures that look like hardware faults. Lifecycle note: Mouser flags this exact ordering code as End of Life (scheduled for obsolescence) while other channels still list it Active — treat it as legacy: require lot and date-code traceability, state whether you need blank or pre-programmed devices, and ask about the newer W25Q32JW series as the forward path in your RFQ. Parameters verified against distributor documentation. We reconfirm manufacturer, density code, lot and traceability against the offered lot before quotation and reply within 24 hours.

AT24C256C-SSHL-T is a Microchip Technology 256 Kb I2C serial EEPROM in SOIC-8, tape and reel — for calibration data, configuration tables and event logs in industrial and consumer systems. 1 MHz I2C, a 5 ms write cycle and 1.7 V to 5.5 V operation is the selection point: fast bus speed plus a supply range covering both 1.8 V logic and 5 V legacy rails on one part — the 1.7 V floor means reads and writes keep working as a battery discharges toward empty. Selection advice: the −T suffix denotes tape and reel for SMT lines; for prototype quantities ask about cut-tape options in your RFQ; the SSHL code pins the SOIC-8 package — quote the full ordering code to match your footprint. EEPROM write endurance is finite, so budget write cycles during design; for high-frequency data logging, ask about FRAM alternatives in your RFQ. The 1 MHz Fast-mode Plus rate doubles the classic 400 kHz EEPROM ceiling — mind pull-up and bus capacitance in layout, as Fm+ is less forgiving than standard mode. Microchip lists this part as Active through distribution. Parameters verified against distributor and manufacturer documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

24LC256-I/SN is a 256 Kb I2C serial EEPROM from Microchip Technology in an 8-pin SOIC package, for nonvolatile storage of calibration data, configuration and event logs in industrial systems. Its advantage is the I2C bus: two wires, multiple devices per bus and byte-level write granularity, which keeps the storage subsystem simple and cheap. Selection advice: the I/SN suffix denotes the industrial temperature grade in SOIC-8 — the 24LC256 ships in several packages and grades, so match the full code to your footprint and operating range. EEPROM has finite write endurance, so confirm your write-cycle budget during design; for high-write-frequency logging, consider FRAM instead. Ordering note: the 24LC256T-I/SN code is this same device supplied on tape and reel (the T in the Microchip ordering code denotes Tape & Reel); electrical specifications are identical. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

FM24CL64B-GTR is Infineon’s 64-Kbit (8K × 8) serial F-RAM — ferroelectric non-volatile memory with a 1 MHz I2C interface in SOIC-8 — for data logging and configuration storage that outlasts EEPROM: industrial controllers, meters, and event recorders. The selection point is endurance: 10 trillion (10^13) read/write cycles with NoDelay writes, roughly ten million times the write endurance of serial EEPROM, plus 121-year data retention. It is a drop-in hardware replacement for I2C EEPROMs — same pinout and protocol — so an existing EEPROM footprint can be upgraded without a board spin. Selection advice: the ‘GTR’ suffix is tape-and-reel packing (2,500/reel); Infineon lists the part as active and preferred with availability planned to at least 2033, which suits long-lifecycle industrial programs. It operates 2.7–3.65 V, fitting 3.3 V systems directly but needing level translation on 5 V I2C buses. Infineon rates it Industrial qualification — for automotive programs confirm the grade with Infineon before specifying. Parameters trace to the manufacturer datasheet; state quantity, packing and date-code requirements in your RFQ — we reconfirm the offered lot before quotation and reply within 24 hours.

IS62WV51216BLL-55TLI is ISSI’s 8-Mbit asynchronous SRAM — 512K × 16, 55 ns access — in TSOP-44, for MCU external memory where a simple parallel bus beats SDRAM complexity: display frame buffers, data-acquisition buffers, and legacy controller designs. The wide 2.5–3.6 V supply fits both 3.3 V and lower-voltage rails, and the asynchronous interface needs no clock, refresh controller, or init sequence — just address, data and three control lines. Selection advice: the ‘-55TLI’ code is the 55 ns TSOP lead-free industrial-temperature (-40 to +85 °C) ordering option, shipped in trays; for reel packing quote the -TR suffixed code. At 55 ns it suits MCU bus speeds below ~18 MHz — for faster external memory use a synchronous SRAM or SDRAM instead. Not automotive-qualified per distributor data; for automotive memory specify an AEC-Q100 part. Parameters trace to the manufacturer datasheet; state quantity, packing and date-code requirements in your RFQ — we reconfirm the offered lot before quotation and reply within 24 hours.

MT48LC16M16A2P-6A:G is Micron’s 256-Mbit SDR SDRAM — 16M × 16 organization, 167 MHz (-6A = 6 ns) clock, 3.3 V, TSOP-54 — the classic parallel SDRAM for MCU/MPU external memory: display buffers, embedded-Linux board memory, and legacy industrial controllers. The synchronous interface with programmable burst lengths (1/2/4/8/full page) and auto-refresh hides DRAM complexity behind a standard controller — most Cortex-A/M MPUs with an SDRAM controller drive it directly. Selection advice: this is a previous-generation SDRAM family — Mouser lists the industrial-temp -6A IT:G TR ordering code as Obsolete, so treat availability as lot-dependent and confirm before designing it into new products; current designs generally use DDR3/DDR4 or LPDDR. Where it still wins is drop-in repair and lifetime extension of existing boards wired for the MT48LC pinout. The ‘:G’ denotes the lead-free version. Parameters trace to the manufacturer datasheet; state quantity, packing and date-code requirements in your RFQ — we reconfirm the offered lot before quotation and reply within 24 hours.

MT25QL128ABA1ESE-0SIT is a 128 Mb quad-I/O serial NOR Flash from Micron Technology in an SOP2-8 package, for high-performance embedded storage — firmware images and execute-in-place code. Quad-I/O is the selection point over standard SPI flash: four data lines multiply the read throughput, which shortens boot time and enables execute-in-place without shadowing to RAM. Selection advice: confirm your controller supports quad-I/O mode before specifying this part — in single-SPI mode you pay for speed you cannot use. As firmware-critical flash, require lot and date-code traceability and state whether you need blank or pre-programmed devices in your RFQ. We reconfirm the offered lot before quotation and reply within 24 hours.

MX25L12835FMI-10G is Macronix’s 128-Mbit serial NOR flash — 16M × 8, SPI/QPI up to 104 MHz, 2.7–3.6 V, SOP-16 — for firmware storage and execute-in-place: MCU boot flash, OTA update partitions, and data logging. The ‘-10G’ is the 104 MHz speed grade; the wide 16-SOIC package suits hand-solderable and legacy layouts where fine-pitch packages are unwelcome. Selection advice: this is the tube-packed SOP-16 ordering code — for reel packing quote the /TR suffixed code. For new compact designs check Macronix’s smaller package options for the same die, since 16-SOIC costs board area. QPI quad-I/O roughly quadruples read throughput over standard SPI when the controller supports it — verify the MCU’s QSPI peripheral before counting on the headline speed. Active at distribution. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

KM3V6001CM-B705 is a Samsung low-power mobile DRAM (LPDDR) in an FBGA package, specified for embedded memory expansion where power budget matters — mobile, handheld and always-on embedded designs. Its advantage over standard DRAM is the low-power operating profile, which directly extends battery life and eases thermal design in compact enclosures. Selection advice: mobile DRAM is qualified by exact organization and configuration, so the complete ordering code including the -B705 suffix must match your BOM — a different suffix can mean a different packing or configuration that your memory controller timing was not validated against. For procurement, state your quantity, target packing and date-code requirements in the RFQ; memory is lot-sensitive and we reconfirm manufacturer, code, lot and traceability against the offered lot before quotation, with a reply within 24 hours.

MT41K128M16JT-125 is a Micron 2 Gb (128M × 16) DDR3L SDRAM in a 96-ball FBGA package — the 1.35 V low-voltage DDR3 workhorse for routers, set-top boxes, industrial gateways and display controllers. The DDR3L 1.35 V operation is the selection point: lower rail power and simpler PMIC design than 1.5 V DDR3, while the -125 speed bin (1.25 ns, DDR3-1600, CL11) is the fastest DDR3L grade and gives timing headroom on congested layouts. Selection advice: this exact code carries no temperature suffix, which in Micron ordering maps to the commercial 0 to 95 °C grade — do not assume industrial or automotive grades; those require the IT:K, AAT:K or AUT:K suffixes and must be confirmed against the full ordering code on the Micron datasheet before any automotive or wide-temperature design. A single ×16 chip gives a 16-bit bus; pair two for 32-bit controllers. Parameters verified against Micron distributor listings (Newark/Farnell) for the -125:K family. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

DS2430AP+T&R is an Analog Devices (Maxim) 256-bit (32 × 8) 1-Wire EEPROM in a 6-pin TSOC package — the board-identity and calibration-storage chip for accessories, sensors and consumables. The factory-lasered 48-bit unique serial number with 8-bit CRC and family code 14h is the selection point: every unit is traceable out of the box, which is exactly what anti-counterfeit and aftermarket consumable-management designs need. Selection advice: the 1-Wire interface needs only one data pin plus ground (parasitic power from the line), so a single MCU GPIO identifies the board — but budget the 15.3 kbps data rate and the 2.2 kΩ pull-up timing into your firmware. The 256-bit user EEPROM plus 64-bit OTP application register hold calibration constants and revision status with 40-year retention. The P suffix is the TSOC-6 package, +T&R is tape and reel (4000). Parameters verified against the Maxim DS2430A datasheet and element14/Newark listings. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

M24C02-RMN6TP is an STMicroelectronics M24C02 2-Kbit (256 x 8) serial I2C EEPROM — 400 kHz Fast-mode, 1.8 to 5.5 V supply, in 8-pin SOIC, tape-and-reel packing (TP), -40 to +85 °C. More than 1 million write cycles with 40-year data retention and a hardware Write Control pin is the selection point: configuration, calibration and identity data that survives power cycles and field updates for decades. Selection advice: 2 Kbit is 256 bytes — size the density before ordering, since the M24C family spans 1 Kbit to 16 Kbit in the same footprint and code structure, and running out of bytes mid-project forces a re-layout. The 1.8 V minimum supply suits 1.8 V and 3.3 V logic directly; the 16-byte page write with 5 ms self-timed programming sets the write-throughput budget for logging applications. Use the Write Control pin when field firmware must never corrupt factory calibration. Distributor listings show this code Active. Evidence: ST M24C02 datasheet and DigiKey/Arrow listings confirm 2 Kbit, I2C 400 kHz, 1.8-5.5 V, 8-SOIC and reel packing. Match the full M24C02-RMN6TP code for density, package and packing. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

W25N01GVZEIG is a Winbond W25N01GV 1-Gbit serial (SPI/Quad SPI) SLC NAND flash — 128M × 8 organization, 2.7 to 3.6 V supply, up to 104 MHz clock, in 8-pin WSON (8 × 6 mm), tray packing (IG suffix), -40 to +85 °C. On-chip ECC, bad-block management and a 2 KB page size are the selection point: NAND density at SPI simplicity for data logging, audio/image storage and firmware backup where SPI NOR would cost far more per bit. Selection advice: this is SPI NAND, not SPI NOR — it needs ECC and bad-block handling (handled on-chip here) and does not execute code in place, so for XIP boot use SPI NOR (W25Q family) instead. Important lifecycle note: Mouser and Arrow list this exact ordering code as End of Life / Obsolete — do not design it into new products without confirming supply; for new designs check the W25N01GW/JW successors. For existing builds, confirm lot availability and date code at RFQ. Evidence: Winbond datasheet and Mouser/Arrow listings confirm 1 Gbit, SPI/Quad, 2.7-3.6 V, 104 MHz, WSON-8 and the EOL status. Match the full W25N01GVZEIG code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

S34ML04G200TFI000 is an Infineon (Cypress) S34ML 4-Gbit SLC NAND flash — parallel ONFI 1.0 interface, 512M × 8 organization, 48-pin TSOP, 2.7 to 3.6 V supply, -40 to +85 °C. SLC with 100,000 program/erase cycles and 25 ns sequential access is the selection point: high-endurance, high-throughput bulk storage for embedded systems with a NAND controller — set-top boxes, industrial controllers, networking gear. Selection advice: this is parallel NAND, not SPI — it needs a host NAND controller with ECC and bad-block management, so confirm your SoC or FPGA has one before choosing it over SPI NAND. SLC endurance beats MLC/TLC by orders of magnitude for logging and swap partitions; for code execution in place, use NOR instead. The TFI code is the 48-TSOP industrial-temperature variant — match it exactly, since the family spans voltages, packages and temperature grades. Evidence: Infineon/Cypress S34ML datasheet and distributor listings confirm 4 Gbit SLC, parallel ONFI, 512M × 8, 48-TSOP and 2.7-3.6 V. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

AT24C02D-SSHM-T is a 2 Kb I2C serial EEPROM from Microchip Technology in an 8-pin SOIC package — for storing small configuration blocks, calibration constants and device IDs. The 2 Kb density is the selection point: the smallest standard EEPROM for tiny parameter sets, at the lowest cost per device. Selection advice: the SSHM-T suffix denotes the SOIC-8 package on tape and reel — the AT24C02D ships in several packages, so match the full code to your layout. Confirm your storage need against the 2 Kb capacity; if your parameter set may grow, step up to a larger density in the same family now rather than respinning later. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

AT24C02C-SSHM-T is a Microchip 2Kbit (256 x 8) I2C-compatible 2-wire serial EEPROM in 8-pin SOIC (0.154 in narrow, SS), tape-and-reel packing (T) — 1.7 V to 5.5 V supply, up to 1 MHz clock, 550 ns access time, 5 ms self-timed write cycle, 16-byte page writes, hardware write-protect pin, Schmitt-trigger filtered inputs for noise suppression, 1 M endurance cycles and 100-year data retention, −40 to +85 °C. The 1.7 V floor is the selection point: it shares the rail with 1.8 V logic without a separate regulator, and the standard two-wire I2C protocol with hardware write protection makes it the default configuration store for calibration data, MAC addresses and user settings across consumer and industrial products. Selection advice: the SS is the 8-pin SOIC; the T is tape and reel — the AT24C02C-SSHM-B is the tube-packaged twin for prototype lines. The 2Kbit density fits the single-device address space without paging tricks; for larger stores move up the AT24C family and mind the addressing differences. Microchip lists AT24C02C-SSHM-T as Active. Evidence: Microchip AT24C02C datasheet and distributor listings confirm 2Kbit, 1.7–5.5 V, 1 MHz, 8-SOIC and tape-and-reel packing. Match the full AT24C02C-SSHM-T code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

Microchip lists AT24C64D-SSHM-T as In Production — a 64Kbit I2C serial EEPROM in SOIC-8, 1 MHz clock, 1.7V to 5.5V, -40 to 85 °C, tape and reel. The 64 Kbit density with 1 MHz I2C is the selection point: roomy enough for event logs and multi-page configuration with fast bus transfers. Selection advice: the SSHM-T suffix denotes SOIC-8 on tape and reel — match the full code to your layout and assembly process. EEPROM write endurance is finite, so confirm your write-cycle budget during design. Parameters verified against the Microchip official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

W25N04KVZEIR is a Winbond 4Gb (512M x 8) SLC QspiNAND Flash in 8-pin WSON (8x6mm) — for high-density code and data storage where SPI NOR runs out of room: automotive clusters, surveillance, network gateways and industrial controllers. 2.7V to 3.6V operation with SPI/Quad I/O at up to 104MHz, on-chip bad block management with lookup table, and 1-bit ECC engine keep the NAND array reliable behind a familiar SPI command set. Selection advice: this is the 3V KV series — do not confuse it with the 1.8V KW series (W25N04KW) when your rail is 1.8V-only; the 4Gb density suits designs outgrowing 2Gb serial NAND, and for new programs also compare the GD5F4GM7UE alternative from GigaDevice on this site. In the current NAND tightness, secure die-revision and date-code traceability up front — remarked or wrong-voltage NAND is a field failure, not a bargain. Parameters verified against Winbond documentation and distributor listings. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

AS4C512M16D3LA-12BIN is an Alliance Memory 8Gb (512M x 16) DDR3L SDRAM in 96-ball FBGA dual-die package — for embedded compute, networking and industrial boards needing a second-source DDR3L option: routers, displays and control platforms. 1.35V low-voltage operation at 800MHz (DDR3L-1600) cuts rail power versus 1.5V DDR3 while keeping JEDEC DDR3L timing compatibility, and the x16 organization builds 16- or 32-bit buses with one or two chips. Selection advice: the -12 suffix is the 800MHz speed bin (for 933MHz/1866MT/s specify the -10 bin); the IN suffix is the industrial -40 to +95°C grade — commercial (CN) and automotive (AN) grades use different suffixes, so match the full code to your temperature requirement. Alliance positions this as a Micron MT41K512M16 drop-in alternative — verify ball-out and timing against your controller before swapping. With DRAM pricing in an up-cycle, lock allocation early on DDR3L programs rather than chasing spot lots. Parameters verified against Alliance Memory documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

GD5F2GM7UEYIGR is a GigaDevice 2Gb SLC SPI NAND Flash in WSON-8 (8x6mm) — for cost-sensitive code storage where SPI NOR is too expensive per bit: set-top boxes, smart home, industrial HMI and data-logging designs. 2.7V to 3.6V with standard/dual/quad SPI up to 120MHz (480Mbits/s quad), 2048+128 byte pages, and on-chip ECC (4-bit, enabled by default) that corrects bit errors without host intervention. 100K program/erase cycles and 10-year retention suit write-light firmware duty. Selection advice: the on-chip ECC covers most use, but for safety-critical storage confirm whether your controller adds its own ECC on top — double ECC wastes spare area; the UE code pins the 3.3V WSON-8 ordering option (for 1.8V rails specify the RE code instead). GigaDevice lists this family as automotive-grade capable — for AEC-Q100 programs confirm the qualification suffix with your channel. As a Winbond W25N02KV-class alternative, it dual-sources your serial NAND BOM against single-fab risk. Parameters verified against GigaDevice documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

W25N02KVZEIR is a Winbond 2Gb (256M x 8) SLC QspiNAND Flash in 8-pin WSON (8x6mm) — the sweet-spot density for connected-device firmware: Wi-Fi modules, smart meters, POS terminals and industrial sensors that outgrow SPI NOR but do not need 4Gb. 2.7V to 3.6V with SPI/Quad I/O at up to 104MHz, 2KB pages, on-chip ECC and bad block management LUT, 60K program/erase cycles and 10-year retention. Selection advice: like its 4Gb sibling W25N04KVZEIR this is the 3V KV series — for 1.8V designs use the W25N02KW family instead; the 2Gb density is the most multi-sourced serial NAND size (Winbond, GigaDevice GD5F2GM7, Macronix), so always dual-source it and let price and lead time compete. 700µs typical page program is slower than NOR — size your firmware-update window accordingly. Parameters verified against Winbond documentation and distributor listings. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

W25Q256JVSIQ is a Winbond 256Mb (32M x 8) Serial NOR Flash in SOIC-8 — for large firmware images and execute-in-place code where NAND page management is unwanted: industrial controllers, networking gear and automotive modules. 2.7V to 3.6V with SPI/Quad I/O at up to 133MHz, 4KB sectors for flexible parameter storage, and XiP support so MCUs boot directly from flash. Selection advice: the SIQ suffix pins the SOIC-8 208mil industrial package — for tighter layouts the WSON-8 EIQ code is the smaller twin; at 256Mb you are at the top of cost-effective NOR — beyond this density compare serial NAND (W25N series) on cost per bit, since NOR stops scaling economically. In the current memory tightness, 256Mb NOR is a frequent allocation pinch point — confirm lot traceability rather than accepting remarked stock. Parameters verified against Winbond documentation and distributor listings. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
