The Microchip ATTINY461A-MUR is a compact AVR 8-bit MCU with 20MHz performance and 4KB Flash. Housed in a 32-VFQFN package, it operates from 1.8V to 5.5V and features a temperature sensor, PWM, and watchdog timer. Its small size and rich analog peripherals make it ideal for space-constrained sensing and control applications.
- Integrated Temperature Sensor: Eliminates external thermistors, saving cost and PCB space.
- Wide Voltage Range (1.8V-5.5V): Compatible with both 3.3V and 5V systems without level shifting.
- High-Density Package: 32-VFQFN offers many I/Os in a tiny footprint.
- AVR Efficiency: Executes most instructions in a single clock cycle, maximizing throughput.
Temperature Monitoring
The built-in temp sensor and 20MHz speed allow direct temperature logging without external sensors.
Small Motor Drivers
PWM outputs can control brushed DC motors in drones or robots with 5V logic.
Battery Charger Controllers
1.8V operation and WDT ensure safe charging of single-cell Li-ion batteries.
LED Matrix Displays
4KB Flash stores patterns for small 8x8 LED matrices in signage.
Analog Data Acquisition
Multiple ADC channels can sample potentiometers and sensors for control panels.
Security Tokens
Low power consumption and small package make it suitable for RFID tags or dongles.
