The ATMEGA164PA-AU is an 8-bit microcontroller from Microchip Technology, featuring the high-performance AVR core. It runs at up to 20MHz with 16KB Flash and 1KB RAM, operating from 1.8V to 5.5V. This MCU includes PWM, Brown-out Detect, POR, and WDT, packaged in a 44-TQFP. It is a versatile and cost-effective solution for a wide range of embedded control applications, from industrial automation to consumer electronics.
- High Code Efficiency: The AVR architecture executes most instructions in a single clock cycle, maximizing throughput at 20MHz.
- Flexible Power Supply: Supports 1.8V to 5.5V, simplifying design across mixed-voltage systems.
- Robust Protection: Integrated Brown-out Detect and WDT enhance system reliability in unstable power conditions.
- Compact Footprint: The 44-TQFP package balances pin count with board space, ideal for space-constrained designs.
Home Automation Controllers
The 20MHz AVR core and 16KB Flash handle multiple sensor inputs and relay controls, with the wide voltage range supporting both 3.3V and 5V peripherals.
Motor Speed Controllers
PWM outputs generate variable-frequency drive signals for small DC motors, while the WDT prevents lockups in noisy environments.
Environmental Monitoring Nodes
With 1.8V operation, it can run on solar-charged batteries, collecting temperature and humidity data and transmitting via external RF modules.
Automotive Interior Lighting
The 44-TQFP package and -40°C to 85°C range make it suitable for LED ambient lighting control with PWM dimming in vehicle cabins.
Industrial Timer/Counters
Its 16-bit timers and 1K RAM allow precise event counting and timing sequences for production line automation.
Consumer Appliances
From washing machines to microwave ovens, the ATMEGA164PA provides reliable control logic with Brown-out Reset for safe power-down sequences.
