AVR AVR® ATmega Microcontroller IC 8-Bit 20MHz 16KB (8K x 16) FLASH 44-TQFP (10x10)
Active1,160 in stock

Overview

The ATMEGA164PA-AU is a high-performance, low-power 8-bit AVR RISC-based microcontroller featuring 16KB of self-programmable Flash memory and 1KB of SRAM. It operates at speeds up to 20MHz and includes an on-chip 2-cycle multiplier, making it efficient for computational tasks in a compact 44-TQFP package.

Why Choose This Part

This MCU offers a robust balance of 32 I/O pins and 16KB of Flash in a small surface-mount footprint. It is highly valued for its predictable 131-instruction set, 100,000 cycle EEPROM endurance, and long-term data retention of 20 years at 85C.

Applications

Industrial Sensor Nodes
Utilizing the 10-bit ADC and low power consumption for monitoring environmental or process data.
Home Automation Controllers
Managing lighting, HVAC, and security sensors via I2C, SPI, and USART communication interfaces.
Battery-Powered Handhelds
Leveraging multiple sleep modes and low-power PicoPower technology to extend operational life.
Legacy System Upgrades
Providing a pin-compatible performance boost for older AVR-based designs requiring 16KB of program space.
