The Microchip ATTINY25-20SSUR is a compact 8-bit AVR microcontroller in an 8-SOIC package. It offers 2KB Flash and 128B SRAM, running at up to 20MHz. With a 2.7V to 5.5V supply range, it is designed for simple control tasks. Its integrated PWM, brown-out detection, and watchdog timer provide essential functions for cost-effective designs. This MCU is a reliable choice for basic embedded control in space-limited applications.
- Minimal Footprint: 8-SOIC package fits into tight PCB layouts.
- Cost-Effective: 2KB Flash is sufficient for basic control algorithms.
- Fast Execution: 20MHz clock for responsive real-time tasks.
- Integrated PWM: Directly drives LEDs and small motors without extra ICs.
- Reliable Operation: BOR and WDT prevent glitches in noisy environments.
Small Motor Drivers
With 20MHz speed and PWM, it can drive small DC motors in toys and mini fans with precise speed control.
LED Dimming Modules
Two PWM channels allow independent brightness control for dual-color LED indicators.
Simple Timers and Controllers
Its small SOIC-8 footprint is ideal for replacing discrete logic in timing circuits and appliance timers.
Sensor Signal Conditioning
Built-in ADC reads analog sensors like thermistors and potentiometers for basic monitoring.
Power Supply Sequencing
BOR and WDT ensure proper startup and shutdown sequences in multi-rail power supplies.
Remote Keyless Entry
Low power consumption and small size suit battery-operated key fob transmitters.
