The Microchip ATTINY25-20SU is a low-power, high-performance 8-bit AVR microcontroller in a space-saving 8-SOIC package. It operates at up to 20MHz with a supply voltage from 2.7V to 5.5V. Featuring 2KB of Flash and 128 bytes of SRAM, it integrates essential peripherals like PWM, watchdog timer, and brown-out detection for reliable control in cost-sensitive applications.
- Small Footprint: 8-pin SOIC package reduces board space and is easy to assemble.
- Fast 20MHz Operation: Provides quick response for real-time control tasks.
- Low Power Consumption: Ideal for battery-operated devices with its power-saving sleep modes.
- Robust Protection: Includes brown-out reset and watchdog timer for dependable operation.
Simple Lighting Controllers
With PWM channels and 20MHz speed, it can drive LED dimming or blinking patterns in decorative and indicator lighting.
Battery Management in Small Devices
Its low power consumption and 2.7V minimum voltage make it suitable for monitoring and control in single-cell Li-ion or 3V battery systems.
Sensor Signal Conditioning
The integrated analog comparator and ADC can process signals from temperature, light, or pressure sensors in compact designs.
Power Tool Safety Interlocks
Brown-out detection and WDT ensure safe operation in handheld power tools, monitoring switch states and motor enable signals.
Small Appliance Timers
Its 8-pin package and internal oscillator reduce BOM count for simple timer or sequencing functions in coffee makers or fans.
Automotive Aftermarket Accessories
The -40°C to 85°C range and robust I/O make it viable for add-on modules like seat heaters or window controllers.
