ATMEGA16A DIP IC

ATMEGA16A

ATMEGA16A: 40 PIN AVR Microcontroller

The ATmega16 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega16 A achieves throughputs approaching 1 MIPS per MHz allowing the system designed to optimize power consumption versus processing speed.
