ATTINY85-20PU

ATmega328P-PU is a Microchip ATmega328P 8-bit AVR microcontroller in 28-pin PDIP, tube — 32 KB flash, 2 KB SRAM, 1 KB EEPROM, up to 20 MHz, 1.8 V to 5.5 V supply, 23 I/O, 10-bit ADC, I2C/SPI/USART, −40 °C to +85 °C. The DIP package plus the Arduino ecosystem is the selection point: hand-solderable 8-bit control with the largest hobbyist code base ever — the classic Arduino Uno chip for education, prototypes and legacy products. Selection advice: Microchip lists the ATmega328P as Not Recommended for New Designs — for new products, migrate to a current AVR (ATmega4809) or 32-bit MCU; for repairs, education and legacy builds, we source remaining stock. Note: the catalog also lists ATMEGA328P-PU (all caps) as a separate entry for the same part — confirm which listing your RFQ references so the lot matches. Evidence: Mouser confirms NRND status, PDIP-28, tube packing and the full parameter set.

ATMEGA328PB-AU is a Microchip 8-bit AVR RISC-based microcontroller in 32-pin TQFP — the upgraded ATmega328P with more peripherals: two UARTs, two SPIs and more timers for connected and motor-control designs. The extra peripherals over the 328P is the selection point: P-compatibility with room to grow. Selection advice: the AU denotes TQFP-32 — for new 8-bit designs this is the safer pick over the NRND 328P; for 32-bit headroom, the SAMD21 or STM32F0 lines are the step up. Microchip lists this part as In Production. Parameters verified against the Microchip official product page.

ATTINY84V-10MU is a Microchip 8-bit AVR ATtiny microcontroller in 20-pad WQFN (4x4mm) - for compact sensor nodes, small appliances, remote controls and battery-powered control. 8KB Flash, 512 bytes EEPROM and 512 bytes SRAM with 12 I/O lines, an 8-channel 10-bit ADC, a universal serial interface (USI) and an on-chip temperature sensor is the selection point: a complete small control system in one 4x4mm package with no external memory. The business case is board space and battery life: the V variant runs from 1.8V to 5.5V: up to 4MHz at 1.8V, up to 10MHz at 2.7V and above, so it operates directly from a single lithium cell or a 1.8V logic rail, and picoPower sleep modes stretch battery life in duty-cycled sensing. Evidence: Microchip lists ATTINY84V-10MU as a current ordering code in its ATtiny24/44/84 datasheet, and authorized distribution reports the part as Active. Selection advice: the V suffix is the low-voltage variant - for 20MHz operation order the non-V ATTINY84-20MU instead, since the V part tops out at 10MHz; the MU suffix denotes the 20-pad QFN, which is not pin-compatible with the 14-pin SOIC (SSU) or PDIP (PU) versions, so match the full code to your footprint; budget for debugWIRE tooling, as this QFN package has no full JTAG port. Heat basis: Ranked #4 on hqbuy.com real-time hot list (2026-10-15). Parameters verified against Microchip Technology documentation.

23LC1024-I/P is a Microchip 1-Mbit SPI serial SRAM in 8-pin PDIP — for fast scratchpad memory: data buffering, display framebuffers and audio delay lines. Unlimited read/write endurance at up to 20 MHz SPI is the selection point: RAM speed with none of EEPROM's write-cycle limits. Selection advice: the I/P denotes PDIP-8 — the breadboard-friendly variant; for SMT, the SOIC variant is the pick. Volatile — for non-volatile needs, the 24LC EEPROM series is the sibling; for more speed, the SQI mode doubles throughput. Microchip lists this part as In Production. 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.

24LC256-I/P is a Microchip 256 Kbit I2C serial EEPROM in 8-pin PDIP — for non-volatile storage: configuration data, calibration tables and event logs. 256 Kbit with 1M erase/write cycles is the selection point: the workhorse EEPROM density for embedded designs. Selection advice: the I/P denotes PDIP-8 — the breadboard-friendly variant; for SMT, the SOIC variant is the pick. 64-byte page writes and 400 kHz bus cover most logging needs; for larger storage, step up the 24LC series density. Microchip lists this part as In Production. 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.

MCP1407-E/P is a Microchip high-speed 6 A low-side MOSFET gate driver in PDIP-8 — for driving power MOSFETs and IGBTs from logic: SMPS, motor drives and inverters. 6 A peak drive switching 2500 pF in 20 ns is the selection point: fast, clean gate drive that cuts switching losses. Selection advice: the E/P denotes PDIP-8 — the breadboard-friendly variant; for SMT, the SOIC variant is the pick. -40 to +125 °C suits industrial environments; the TC4420 is the alternate source in the same class. 18 V max supply.

The 256 KB Flash with 100-pin I/O is the selection point: the largest AVR 8-bit device, the chip behind the Arduino Mega, for designs that outgrew smaller AVRs but want to stay in the 8-bit ecosystem. Selection advice: the 16AU suffix denotes the 16 MHz speed grade in TQFP-100 — match the full code to your layout and clock requirements. If your firmware fits in 128 KB, the ATMEGA1280 is the cheaper drop-in alternative in the same package.
