CMOS 8-bit microcontroller, ATMEGA644-20PU, ATMEL
The ATMEGA644-20PU is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, it achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
Features
- Advanced RISC architecture
- High endurance non-volatile memory segments
- Real time counter with separate oscillator
- Programmable serial USART
- External and internal interrupt sources
