The ATTINY261A-SU from Microchip Technology is a versatile 8-bit AVR microcontroller in a 20-SOIC package. It operates from 1.8V to 5.5V at up to 20MHz, with 2KB Flash and 128 bytes SRAM. Unique features include an internal temperature sensor, PWM, brown-out reset, and watchdog timer, making it suitable for analog-rich applications.
- Internal temperature sensor – Eliminates external thermistors, reducing BOM cost.
- Wide voltage range (1.8-5.5V) – Works with low-voltage batteries and standard 5V logic.
- 20-pin SOIC package – Provides more GPIOs for complex interfaces.
- Integrated analog peripherals – PWM and brown-out detection enhance system robustness.
Temperature-Compensated Oscillators
The internal temp sensor allows real-time frequency correction in precision timing modules.
Multi-Channel Lighting Systems
With 20 pins, it can control multiple LED strings with individual PWM dimming in architectural lighting.
Industrial Process Controllers
