The ATMEGA88-20AUR from Microchip is a 20MHz AVR 8-bit microcontroller with 8KB flash and 1KB SRAM. It operates from 2.7V to 5.5V, featuring PWM, WDT, and brown-out detection. In a 32-TQFP package, it is a versatile choice for hobbyist and commercial embedded projects.
- Versatile AVR core: Well-documented architecture with extensive community support.
- Sufficient memory: 8KB flash and 1KB RAM handle moderate firmware complexity.
- Wide voltage range: 2.7V to 5.5V supports both 3.3V and 5V systems.
- Compact 32-TQFP: Balances pin count and board area for compact designs.
Prototyping and Education
The AVR core and 8KB flash are ideal for Arduino-compatible projects and learning embedded systems.
Sensor Interfacing
With 1KB RAM and multiple I/O pins, it reads analog sensors and communicates via UART or I2C in data loggers.
Home Automation
Its 2.7V to 5.5V range and PWM outputs control relays and dimmers in smart home hubs.
Motor Speed Control
20MHz speed and PWM channels enable simple open-loop speed control for small DC fans and pumps.
Battery-Powered Devices
Low-power sleep modes and brown-out detection extend battery life in handheld instruments.
LED Displays
The 32-TQFP package provides enough pins to drive multiplexed 7-segment displays or LED matrices.
