The ATTINY261A-MNR from Microchip is an 8-bit AVR microcontroller designed for extended temperature environments. With a 20MHz core, 2KB flash, and 128 bytes SRAM, it operates from 1.8V to 5.5V. The 32-VFQFN package includes a temperature sensor, PWM, and robust reset features for demanding industrial and automotive applications.
- Extended temperature range: -40°C to 105°C for harsh environments.
- Low power consumption: Ideal for battery-operated remote sensors.
- Compact footprint: 32-VFQFN saves PCB space.
- Integrated analog features: Temperature sensor and comparator reduce external parts.
Automotive Sensor Interfaces
The 105°C rating allows operation under hood or near-engine sensors where heat is a concern.
Industrial Actuator Control
PWM outputs and 20MHz speed enable precise control of valves and solenoids in factory automation.
HVAC Zone Controllers
With temperature sensing and low power, it can manage multiple zones in building climate systems.
Power Tool Safety Modules
