The ATTINY426-MF is an 8-bit AVR microcontroller from Microchip, operating at 20MHz. It provides 4KB flash and 512 bytes RAM in a 20-VFQFN package. With a 1.8V to 5.5V supply range and -40°C to 125°C operation, it is designed for harsh environments.
- 125°C operating temperature: reliable in extreme heat.
- AVR core: efficient C-code execution.
- 20-VFQFN: ultra-compact for space-limited designs.
- Wide voltage range: flexible power sources.
High-Temperature Industrial Sensors
125°C rating allows direct mounting near motors, engines, or furnaces without active cooling.
Automotive Engine Bay Modules
Extended temperature range and 1.8V-5.5V supply make it suitable for under-hood sensors and actuators.
Compact IoT End Nodes
20-pin VFQFN package minimizes PCB area for wireless sensor nodes with battery monitoring.
LED Matrix Drivers
AVR core at 20MHz can refresh small LED matrices with PWM for signage or decorative lighting.
Power Tool Controllers
Robust temperature tolerance supports brushless motor commutation in drills and saws.
Industrial Valve Positioners
WDT and BOR ensure fail-safe operation in critical flow control applications.
