MICROCHIP ATMEGA164P-20AUR

The ATmega164P/V/324P/V/644P/V is a low power, CMOS 8-bit microcontrollers based on the AVR enhanced RISC architecture. The ATmega164P/V/324P/V/644P/V is a 40/44-pins device ranging from 16 KB to 64 KB Flash, with 1 KB to 4 KB SRAM, 512 Bytes to 2 KB EEPROM. By executing instructions in a single clock cycle, the devices achieve CPU throughput approaching one million instructions per second (MIPS) per megahertz, allowing the system designer to optimize power consumption versus processing speed.
