Product Overview

The ATMEGA644P-20PU 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 microcontroller achieves throughputs approaching 1 MIPS per MHz allowing the system designed to optimize power consumption versus processing speed.
  • High-performance, Low-power AVR® 8-Bit Microcontroller
  • Advanced RISC Architecture
  • High Endurance Non-volatile Memory Segments
  • JTAG (IEEE Standard 1149.1 Compliant) Interface
  • Power-on Reset and Programmable Brown-out Detection
  • Internal Calibrated RC Oscillator
  • External and Internal Interrupt Sources
  • Idle, ADC Noise Reduction, Power-save, Power-down, Standby and Extended Standby Sleep Modes
  • 0 to 20MHz at 4.5 to 5.5V Speed Grade
  • 0.4mA Active, 0.1µA Power-down mode, 0.6µA Power-save mode (32kHz RTC) power consumption
