The Microchip ATTINY426-MUR is a tape-and-reel version of the ATTINY426-MU, an 8-bit AVR microcontroller in a 20-VFQFN package. It offers 4KB of flash and 512 bytes of RAM at 20MHz, with a 1.8V to 5.5V supply range. This variant is optimized for automated manufacturing while delivering the same reliable PWM, WDT, and brown-out detection features.
- Manufacturing efficiency: Tape-and-reel format reduces assembly time and cost for high-volume production.
- Same performance as -MU: 20MHz speed and 4KB flash for complex applications.
- Compact QFN package: Ideal for miniaturized PCB designs with exposed pad for heat dissipation.
- Low power operation: 1.8V minimum supply supports energy-harvesting and battery designs.
High-Volume Consumer Electronics
Tape-and-reel packaging facilitates automated SMT assembly for mass production of smart devices.
Battery-Powered IoT Endpoints
1.8V operation and low sleep current extend battery life in wireless sensor nodes.
Multi-Channel LED Controllers
Multiple PWM channels and 20MHz speed drive RGB LED strips with smooth color transitions.
Compact Motor Drivers
The QFN package and fast PWM support mini drone and gimbal motor control.
Environmental Monitoring Loggers
4KB flash stores calibration data and logging routines for temperature/humidity recorders.
Security Keypads and Access Control
Fast wake-up and robust I/O handle matrix scanning and communication with host systems.
