The ATTINY25-20SUR from Microchip Technology is a low-power 8-bit AVR microcontroller in an 8-SOIC package. It operates from 2.7V to 5.5V and runs at up to 20MHz, with 2KB Flash and 128 bytes SRAM. Integrated PWM, brown-out reset, and watchdog timer make it a versatile choice for compact, cost-sensitive embedded designs.
- High-speed AVR core (20MHz) – Executes instructions in a single cycle, offering superior performance per MHz.
- Surface-mount 8-SOIC – Enables automated assembly and space-saving PCB layouts.
- Rich peripheral set – PWM, brown-out detect, and WDT reduce external components.
- Wide voltage range (2.7-5.5V) – Compatible with both 3.3V and 5V systems.
Compact Motor Drivers
The 20MHz AVR core and PWM channels allow precise speed control of small brushed DC motors in drones and robotics.
Smart Sensors
With 2KB Flash and low power, it can process temperature or light data and communicate via I2C in building automation.
Battery Management
Its 2.7V minimum and brown-out detection protect lithium batteries from deep discharge in portable electronics.
