The ATTINY861A-PU is an 8-bit AVR microcontroller from Microchip Technology, offering 8KB flash memory and 512 bytes of SRAM in a 20-pin DIP package. It operates from 1.8V to 5.5V at speeds up to 20MHz, featuring a rich analog peripheral set including a 10-bit ADC, analog comparator, and internal temperature sensor. With built-in brown-out detection, power-on reset, and watchdog timer, this MCU provides reliable operation in industrial and consumer applications.
- Wide voltage range (1.8V-5.5V) enables direct battery operation without external regulators, simplifying power design.
- Integrated temperature sensor eliminates the need for external sensing components, reducing BOM cost.
- 20MHz AVR core delivers 20 MIPS throughput for real-time control tasks.
- DIP package allows easy prototyping and through-hole assembly for hobbyist and industrial boards.
Industrial Sensor Interfaces
The 20MHz AVR core with 8KB flash and 512B SRAM handles sensor conditioning and simple PID loops in temperature or pressure transmitters, operating from 1.8V to 5.5V.
Battery-Powered Handheld Tools
Low-voltage operation down to 1.8V and multiple sleep modes extend battery life in portable measurement devices, while the internal temperature sensor enables cold-junction compensation.
Motor Control for Small Appliances
On-chip PWM channels and a 10-bit ADC allow closed-loop speed control for brushless DC fans or pumps, with brown-out detection ensuring safe shutdown.
Automotive Aftermarket Modules
The -40°C to 85°C range and WDT make it suitable for cabin lighting controllers or seat position memory modules in harsh environments.
Smart Lighting Systems
Use the PWM outputs to drive LED dimming with 8-bit resolution, while the analog comparator detects ambient light for automatic adjustment.
Data Logging Nodes
With 512B RAM and SPI/I2C interfaces, it can buffer and transmit sensor data to a central hub in building automation networks.
