ATTINY84V-10MU

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. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

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. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ATtiny85-20PU is a Microchip 8-bit AVR microcontroller in 8-pin PDIP — for the tiniest control tasks: LED effects, simple sensors and glue-logic replacement. Eight pins with 1.8–5.5 V operation is the selection point: programmable control where a 555 timer used to be the answer. Selection advice: the 20PU denotes the 20 MHz PDIP-8 in tube — the breadboard-friendly variant; for SMT, the SOIC variant is the pick. For more I/O or peripherals, step up to the ATtiny84 or ATmega series. 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.

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.

ATMEGA2560-16AU is a high-pin-count 8-bit AVR microcontroller from Microchip Technology with 256 KB Flash in a 100-pin TQFP package — for I/O-heavy embedded control. 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. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ATMEGA328P-AU is an 8-bit AVR microcontroller from Microchip Technology in a 32-pin TQFP package — for embedded control and instrumentation. This is the chip behind the Arduino Uno: the largest hobbyist and educational ecosystem of any microcontroller, which means code examples and libraries for nearly every sensor. Selection advice: the AU suffix denotes TQFP-32 — the ATMEGA328P also ships in PDIP-28 (PU suffix), so match the full ATMEGA328P-AU code to your layout. The P (picoPower) variant is the low-power pick over the non-P version. Confirm your Flash and peripheral needs against the datasheet.

ATMEGA32U4-AU is a Microchip 8-bit AVR microcontroller with native USB in 44-pin TQFP — for USB HID devices: custom keyboards, dongles and game controllers. The on-chip USB device controller is the selection point: Arduino Leonardo-class USB without an external bridge. Selection advice: the AU suffix denotes TQFP-44 — the same chip as the Leonardo; for new USB designs, compare 32-bit USB MCUs (SAMD21, STM32F0) for more headroom, but the AVR toolchain and community remain the fastest path for simple HID. 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.

ATSAMD21G18A-AU is a 32-bit Arm Cortex-M0+ microcontroller from Microchip (SAMD21 family) in TQFP-48 — with native full-speed USB for battery-powered and USB-peripheral designs. The on-chip USB is the selection point: it removes the external USB bridge chip that simpler MCUs need. Selection advice: the G18A denotes the 256 KB Flash / 32 KB SRAM variant — pick it when you need USB plus headroom for stacks; drop to a smaller SAMD21 for cost. The -AU suffix denotes the TQFP-48 package; -U at the end is the standard temperature grade. This is a mature line with broad ecosystem support. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ATSAMD51J20A-AU is a Microchip SAM D51 32-bit microcontroller with ARM Cortex-M4F core at 120 MHz — 1 MB Flash, 256 KB SRAM in 64-pin TQFP. The selection point is the peripheral set for its class: 24-channel 12-bit ADC, dual 12-bit DAC, USB device/host, QSPI with XiP, and PTC touch controller, all on a 1.71V to 3.63V supply. Selection advice: the J20A code pins the 64-pin TQFP with 1 MB Flash — for 48-pin designs the G18A is the smaller sibling, and for Ethernet MAC plus larger RAM the SAME51 series is the step up. Microchip lists this part as Active with extended lead times on popular codes — confirm the offered lot date code in your RFQ.
