ATMEGA32U4 Datasheet – 8-Bit AVR Microcontroller – ATMEL

Part Number: ATMEGA32U4

Function: 8-bit AVR Microcontroller

Package: 44-pin QFN/TQFP TYPE

Manufacturer: Atmel Corporation




The low-power Atmel 8-bit AVR RISC-based microcontroller featuring 32KB self-programming flash program memory, 2.5KB SRAM, 1KB EEPROM, USB 2.0 full-speed/low speed device, 12-channel 10-bit A/D-converter, and JTAG interface for on-chip-debug. The device achieves up to 16 MIPS throughput at 16 MHz. 2.7 – 5.5 Volt operation.

By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, allowing you to optimize power consumption versus processing speed.
