M24C02-RMN6TP

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.

AT21CS11 is a Microchip Technology 1-Kbit (128 x 8) single-wire, I/O-powered serial EEPROM with a unique factory-programmed 64-bit serial number — for identifying and authenticating remote items such as cartridges, cables and disposable attachments where only two wires (SI/O plus ground) can reach the device. The single-wire interface is the selection point: one SI/O pin carries both power (drawn from the pull-up) and data, so a detachable accessory needs no extra connector pins, battery or regulator — and the 2.7 V to 4.5 V self-powered range suits Li-ion-powered devices, versus the AT21CS01 which covers 1.7 V to 3.6 V. It runs up to 125 kbps in high-speed mode, with 8-byte page writes, a 5 ms self-timed write cycle, 1,000,000 write-cycle endurance, 100-year data retention, IEC 61000-4-2 Level 4 ESD protection, and -40°C to +85°C operation. Four 256-bit zones can each be permanently locked read-only, and the 256-bit security register carries the factory serial number plus user-programmable lockable bytes, which is what makes the part an anti-counterfeit and warranty-tracking device rather than a plain memory. Selection advice: choose AT21CS11 over AT21CS01 when the pull-up rail is 2.7 V to 4.5 V; choose it over a 2-wire I2C EEPROM when pin count, connector cost or detachable-assembly simplicity matters more than bus speed. The base MPN covers several packages (2-pad XSFN, 3-lead SOT-23, 8-lead SOIC, 4-ball WLCSP), so quote the full ordering code (e.g. SSH10 for SOIC-8) to match your footprint and assembly process.

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.

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.

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.

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.

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.

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.

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.
