The Microchip ATTINY841-MUR is a low-power 8-bit AVR microcontroller in a 20-WFQFN package. It operates from 1.7V to 5.5V and runs at up to 16MHz, making it an excellent choice for battery-powered and portable devices. With 8KB of flash memory and 512 bytes of SRAM, it provides ample resources for sensor interfacing, PWM control, and communication tasks. The device includes a PWM module and is designed for minimal power consumption in active and sleep modes.
- Ultra-Low Voltage Operation (1.7V): Extends battery life in single-cell applications, reducing the need for boost converters.
- Large Flash for Size (8KB): Allows more complex firmware than typical small-pin MCUs, enabling feature-rich applications.
- Compact 20-WFQFN Package: Occupies minimal board area, ideal for miniaturized consumer electronics.
- Integrated PWM: Simplifies motor and LED control without external PWM generators.
Wearable Fitness Trackers
The 1.7V minimum supply voltage allows direct operation from a single coin cell, while the 8KB flash can store activity algorithms and user profiles.
Smart Sensor Tags for Logistics
Its small 20-WFQFN package and low power consumption make it perfect for temperature/humidity logging tags attached to shipping containers.
Portable Medical Injectors
The 16MHz speed and PWM outputs can precisely control a small motor for drug delivery, with the wide voltage range accommodating varying battery levels.
Consumer Electronics Remote Controls
With 8KB flash, it can handle complex IR/RF protocols, while the low-power sleep mode extends remote battery life.
LED String Light Controllers
PWM channels can drive multiple LED colors, and the compact package fits inside small decorative housings.
Security Alarm Sensors
The fast wake-up time and integrated analog comparator enable quick response to magnetic reed switch changes in door/window sensors.
