ATMEGA32A is a 40 pin, 8-bit AVR RISC-based microcontroller from Atmel. It is a low power, high performance microcontroller featuring 32KB self-programming flash program memory, 2KB SRAM, 1KB EEPROM, 8 channel 10-bit A/D converter and JTAG interface for on-chip-debug. The device acheives 16 MIPS throughput at 16 Mhz at 2.7-5.5V 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.
