The ATMEGA88P-20AU is an 8-bit AVR microcontroller from Microchip. It runs at up to 20MHz and provides 8KB of flash memory and 1KB of SRAM. Operating from 2.7V to 5.5V, it includes PWM, WDT, and brown-out detection. The 32-TQFP package makes it suitable for compact designs in consumer and industrial applications.
- Proven AVR Architecture: Simple instruction set and extensive community support reduce development time.
- Wide Voltage Operation: 2.7V-5.5V enables battery or 5V logic compatibility.
- Compact Footprint: 32-TQFP saves PCB space for space-constrained designs.
- Reliable Operation: Built-in WDT and brown-out reset prevent system lockups.
Sensor Nodes
The 20MHz AVR core with 8KB flash is ideal for reading analog sensors and transmitting data over UART or SPI.
Small Appliances
Its 2.7V-5.5V range allows direct battery operation or 5V USB power for coffee makers, kettles, and timers.
LED Lighting Controllers
PWM channels enable smooth dimming and color mixing in RGB LED strips.
