The Microchip ATTINY261A-MUR is a high-performance 8-bit AVR microcontroller in a compact 32-VFQFN package. It delivers 20MHz processing speed with 2KB flash and 128 bytes of SRAM. Operating from 1.8V to 5.5V, it integrates a temperature sensor, PWM, and watchdog timer, making it ideal for cost-sensitive embedded control applications.
- Ultra-low voltage operation: 1.8V minimum enables direct battery operation without regulators.
- Integrated temperature sensor: Eliminates external sensor ICs, reducing cost and board space.
- High-speed AVR core: 20MHz throughput for real-time control tasks.
- Robust protection: Brown-out reset and watchdog timer enhance system reliability.
Battery-Powered Sensor Nodes
The 1.8V minimum supply voltage and low-power sleep modes enable long battery life in IoT and remote monitoring devices.
Temperature Monitoring Systems
The integrated temperature sensor reduces BOM cost and simplifies PCB layout for thermostatic controls or environmental loggers.
PWM Motor Control
With 20MHz operation and PWM peripherals, it can generate precise control signals for small DC motors in toys or pumps.
Portable Consumer Electronics
The compact 32-VFQFN package and 5.5V maximum voltage allow direct interfacing with Li-ion batteries and space-constrained wearables.
Automotive Interior Modules
Operating from -40°C to 85°C, it suits non-critical automotive applications like seat control or lighting modules.
Industrial Process Timers
The WDT and brown-out detection ensure reliable operation in noisy industrial environments, preventing system lockups.
