About the Item

ATMEL ATmega640 AVR 8-bit Microcontroller with 64KB Flash, 4KB EEPROM, 8KB RAM

The ATmega640 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 ATmega640 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
