The ATMEGA164P-20MU is an 8-bit AVR MCU from Microchip with 16KB flash and 1KB SRAM. It runs at 20MHz with a 2.7V-5.5V supply, featuring brown-out detection, POR, PWM, and WDT. The 44-VFQFN package is suited for compact industrial and automotive applications.
- Wide 2.7V-5.5V supply – simplifies power design with 3.3V or 5V rails.
- 20MHz performance – handles real-time control loops efficiently.
- 44-VFQFN package – small footprint with exposed pad for thermal relief.
- Mature AVR architecture – extensive code libraries and tools available.
Automotive Body Electronics
5.5V operation and 20MHz speed handle window lift and mirror control with PWM outputs.
Industrial Automation
Brown-out detection and WDT ensure fail-safe operation in PLC I/O modules.
Consumer Appliances
16KB flash supports wash cycle algorithms in washing machines and dishwashers.
Sensor Interfaces
1KB RAM and fast ADC conversion enable real-time temperature and pressure monitoring.
Power Tools
High-voltage tolerance and robust I/O drive brushless DC motors with external drivers.
Smart Meters
Low-power sleep modes and wide voltage range support utility metering with battery backup.
