ATmega32U2 The ATmega32U2 is an AVR low-power CMOS 8-bit microcontroller based on enhanced RISC architecture. By executing instructions in a single clock cycle, the ATmega32U2 achieves throughputs of almost 1 MIPS per MHz. This allows system designers to optimise power consumption in comparison to processing speed. Features - High-performance, low-power AVR 8-bit microcontroller - Advanced RISC architecture - 125 instructions - usually in a single clock cycle - 32 x 8 general purpose registers - Up to 16 MIPS throughput at 16 MHz - Non-volatile program and data memory - 32 K in-system Flash - 1024-byte EEPROM - 1024-byte internal SRAM - Write/erase cycles: 10,000 Flash/100,000 EEPROM - Data retention: 20 years at 85°C/100 years at 25°C (1) - Optional boot code section with independent lock bits - USB 2.0 full-speed-device with interrupt - Complies with USB specification rev. 2.0 - 48-MHz PLL for full-speed bus mode: Data transfer rates of 12 Mbit/s - Completely independent 176-byte USB DPRAM for endpoint memory allocation - Endpoint 0 for control transfers: from 8 to 64 bytes - 4 programmable endpoints - USB bus trip on microcontroller request - Peripheral functions - One 8-bit timer/counter with separate prescaler and comparison mode (two 8-bit PWM channels) - One 16-bit timer/counter with separate prescaler, comparison and capture mode (three 8-bit PWM channels) - USART with SPI master mode and hardware flow control (RTS/CTS) - Master/slave SPI serial interface - Programmable watchdog timer with separate on-chip oscillator - On-chip analogue comparator - Alarm and wake-on-connection - On-chip debug interface (debugWIRE) - Special microcontroller characteristics - Power-on-reset and programmable brown-out recognition - Internal calibrated oscillator - External and internal interrupt sources - Five sleep modes: standby, power save, power-down, standby and extended standby - 22 programmable I/O lines - Operating voltages: 2.7 - 5.5 V - Operating temperature: industrial: -40°C to +85°C - Maximum frequency - 8 MHz at 2.7 V - 16 MHz at 4.5 V https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2017-08-05 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2018-01-10 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2018-03-26 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2018-05-05 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2018-06-25 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2018-12-16 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2019-02-13 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2019-04-01 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2019-06-20 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2021-05-13 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2021-12-13 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2022-05-30 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2022-10-21 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2022-12-09 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2023-02-17 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2023-04-07 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2023-05-28 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2023-08-18 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2024-05-22 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2024-07-04 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2025-12-14 https://elecena.pl/product/9695593/atmega32u2-au-mcu-atmega-avr-risc-32-kb-16-mhz-tqfp-32 2026-01-03
