Microchip Technology ATmega32U4 8-bit
Microcontroller (MCU) with USB Controller is a low-power, AVR® RISC-based
device featuring 32KB self-programming flash program memory, 2.5KB SRAM, 1KB
EEPROM, USB 2.0 full-speed/low-speed device module, 12-channel, 10-bit
analog-to-digital converter, and JTAG interface for on-chip-debug. This
Microchip device achieves up to 16 MIPS throughput at 16MHz and 2.7 to 5.5V
operation. By executing powerful instructions in a single clock cycle,
Microchip ATmega32U4 MCU achieves throughputs approaching 1MIPS per MHz,
allowing you to optimize power consumption versus processing speed.
