The ATTINY28V-1AU from Atmel is a low-power 8-bit AVR microcontroller. It operates at 1.2MHz with a supply voltage from 1.8V to 5.5V, featuring 2KB of flash memory. The 32-TQFP package provides ample I/O for basic control tasks. Integrated POR and WDT enhance reliability in battery-operated and industrial applications.
- Ultra-low power: 1.8V operation and 1.2MHz clock minimize energy consumption for portable devices.
- Compact 32-TQFP: Offers more I/O pins than smaller packages while remaining board-space efficient.
- Simple architecture: AVR core is easy to program with extensive community and official documentation.
- Built-in reliability: POR and WDT reduce external component count and improve system stability.
Battery-Powered Remote Controls
The 1.8V minimum supply and 1.2MHz low-frequency operation allow direct CR2032 coin-cell usage, extending battery life in TV and IR remote controls.
Simple LED Lighting Controllers
With 2KB flash, it can store PWM patterns for decorative LED strips, while the WDT ensures automatic reset if firmware hangs.
Low-Speed Data Loggers
The AVR core at 1.2MHz is sufficient for periodic sensor sampling and storing data to external EEPROM, with POR ensuring clean startup.
Toy and Novelty Electronics
Its low cost and small TQFP footprint make it suitable for sound effects or light sequences in battery-operated toys.
Analog Signal Conditioning
Although no ADC is specified, the MCU can control external analog switches and amplifiers for signal routing in test equipment.
Automotive Aftermarket Accessories
The -40°C to 85°C range supports under-dash modules like simple timer circuits for interior lighting.
