The Microchip ATTINY426-XFR is an 8-bit AVR microcontroller designed for extended temperature operation. It offers 4KB of Flash and 512 bytes of SRAM, running at up to 20MHz from a 1.8V to 5.5V supply. Housed in a 20-SSOP package, it integrates PWM, a watchdog timer, and brown-out detection, providing a compact and reliable solution for automotive and industrial control.
- Extended temperature range (-40°C to 125°C): Enables deployment in engine bays and industrial ovens where standard MCUs fail.
- 20MHz performance: Ensures responsive control loops even in time-critical applications like actuator regulation.
- 20-SSOP package: Offers a smaller footprint than DIP while remaining through-hole compatible for prototyping.
- Integrated analog peripherals: Reduces external component count by providing ADC and comparator on-chip.
Automotive Sensor Nodes
The 125°C junction temperature rating allows placement near engines or exhaust systems. The 20MHz AVR core can handle CAN or LIN message processing when paired with an external transceiver.
Industrial Actuator Control
With PWM outputs and a robust WDT, this MCU can drive solenoids or valves in factory automation, ensuring fail-safe operation in high-temperature zones.
HVAC Zone Controllers
The wide voltage range and 4KB Flash are perfect for implementing thermostat algorithms, while the SSOP package fits neatly on compact control boards.
Power Supply Monitoring
Its ADC can monitor output voltages and currents, while the brown-out detector ensures the MCU resets cleanly during power dips, protecting downstream equipment.
Portable Test Instruments
For handheld meters, the low-power sleep modes and 1.8V operation extend battery life, while the 20MHz speed allows fast measurement updates.
Lighting Ballasts
The PWM channels can generate high-frequency drive signals for LED or fluorescent ballasts, with the extended temperature range supporting enclosed fixtures.
