ATMEGA32U4-MU QFN-44

Surface Mount 8-Bit Microcontroller Chip 16MHZ

Device Overview

         The low-power Microchip 8bit AVR RISC-based microcontroller featuring 32kB self-programming flash program memory 2.5KB SRAM, 1KB EEPROM, US8 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.
