Product Description
ATMEGA644PA-AUR Microcontroller MCU
High-performance, low-power 8-bit 20MHz AVR microcontroller with advanced RISC architecture and comprehensive peripheral set.
Product Overview
The ATMEGA644PA-AUR is a low-power CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture. This 40/49-pin device features 64KB Flash memory, 4KB SRAM, and 2KB EEPROM. With single clock cycle instruction execution, it achieves CPU throughput approaching one million instructions per second (MIPS) per megahertz, enabling optimal power consumption versus processing speed balance.
