ATMEGA32U4-AUR Datasheet PDF - Microchip

The ATMEGA32U4-AUR is a low-power 8-bit AVR RISC-based Microcontroller features 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 16MHz, 2.7 to 5.5V 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.
