The ATTINY25-20SNR is a compact 8-bit AVR microcontroller from Microchip, offering a perfect balance of simplicity and performance. It runs at up to 20MHz with a supply voltage of 2.7V to 5.5V, and includes 2KB Flash and 128 bytes RAM. The device features PWM, brown-out detection, and a watchdog timer, all in a standard 8-pin SOIC package. Its wide temperature range and robust design make it a reliable choice for automotive, industrial, and consumer applications.
- Wide voltage range (2.7-5.5V) – simplifies interfacing with both 3.3V and 5V peripherals.
- High-temperature rating (105°C) – extends usability in harsh environments.
- 20MHz AVR core – provides fast, predictable execution for time-sensitive tasks.
- Compact SOIC-8 – easy to integrate into space-limited designs.
- Low-power modes – reduces energy consumption in battery-operated devices.
Small Motor Control
PWM outputs and 20MHz speed drive micro-motors in toys and small pumps.
LED Lighting Effects
2KB Flash stores patterns for RGB LED strips in decorative lighting.
Battery-Powered Timers
Low-power sleep modes and wide voltage range suit kitchen timers and alarms.
Sensor Trigger Modules
Fast wake-up and interrupt handling enable immediate response to motion sensors.
Automotive Accessory Control
105°C rating allows use in engine bay modules for window or mirror control.
Simple Data Logging
128 bytes RAM and EEPROM (if available) store small calibration data.
