ATMEGA1284P-AU Description
Low power, CMOS, 8-bit microcontrollers based on the AVR® improved RISC architecture are the ATmega164A/PA/324A/PA/644A/PA/1284/P. The 40/49-pin ATmega164A/PA/324A/PA/644A/PA/1284/P is a device with flash memory ranging from 16 KB to 128 KB, 1 KB to 16 KB SRAM, and EEPROM ranging from 512 Bytes to 4 KB. The devices' ability to process instructions in a single clock cycle results in CPU throughput that is close to one million instructions per second (MIPS) per megahertz. This enables the system designer to balance power usage and processing speed.
ATMEGA1284P-AU Features
