Quick Detail:
8-bit Microcontroller with 16/32/64K Bytes In-System Programmable
Flash
Description:
The ATmega164/324/644 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 ATmega164/324/644
achieves throughputs approaching 1 MIPS per MHz allowing the system
designer to optimize power consumption versus processing speed.
