The Microchip ATTINY261A is a high-temperature 8-bit AVR microcontroller in a 32-VFQFN package. It operates from 1.8V to 5.5V and runs at up to 20MHz, providing a balanced mix of performance and power efficiency. With 2KB Flash and 128 bytes RAM, it integrates a temperature sensor, PWM, and watchdog timer. Its extended -40°C to +125°C range makes it ideal for harsh environments.
- Extended Temperature Range: -40°C to +125°C operation enables use in automotive and industrial settings.
- Wide Voltage Flexibility: 1.8V to 5.5V supports both battery and regulated 5V designs without level shifters.
- Integrated Temperature Sensor: Eliminates the need for external thermistors, saving cost and board space.
- High-Speed AVR Core: 20MHz throughput allows complex algorithms in real-time control.
- Exposed Pad Package: Improves thermal performance for power-dissipating applications.
High-Temperature Industrial Sensors
With an operating range up to 125°C, this MCU can be placed directly on hot machinery or near engines to monitor temperature, vibration, or pressure without external cooling.
Automotive Body Electronics
The 5.5V capability allows direct connection to automotive 5V rails, while the temperature sensor and PWM support interior lighting or seat control modules.
Smart Battery Management
Its low-voltage operation and internal temperature sensor enable accurate state-of-charge monitoring in Li-ion battery packs, with the WDT ensuring safe shutdown.
Portable Power Tools
The robust 125°C rating and 20MHz speed make it suitable for motor control in drills or saws, where heat and vibration are common.
LED Matrix Displays
With enough I/O and PWM channels, it can drive small LED matrices for signage or status indicators, operating from a single 3.3V supply.
HVAC Zone Controllers
The wide voltage range and temperature sensing allow it to manage damper actuators and report ambient temperature in building automation systems.
