MICROCHIP ATMEGA1284-AUR

The ATmega164A/PA/324A/PA/644A/PA/1284/P is a low power, CMOS 8-bit microcontrollers based on the AVR enhanced RISC architecture. The ATmega164A/PA/324A/PA/644A/PA/1284/P is a 40/49-pins device ranging from 16 KB to 128 KB Flash, with 1 KB to 16 KB SRAM, 512 Bytes to 4 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.
