The Microchip ATTINY3226-SF is an 8-bit AVR microcontroller with 32KB flash and 3KB SRAM in a 20-SOIC package. It operates from 1.8V to 5.5V and runs at up to 20MHz, delivering robust performance for demanding applications. Rated for -40°C to 125°C, it is ideal for automotive and industrial environments. Integrated PWM, brown-out detection, power-on reset, and watchdog timer ensure reliable operation.
- Automotive temperature range (125°C): Suitable for under-hood and high-heat applications.
- Large memory (32KB flash): Supports complex control algorithms.
- 20-pin SOIC package: More I/O options than smaller packages.
- Wide voltage range: Works with 3.3V and 5V systems.
- Integrated protection: BOD, POR, and WDT enhance reliability.
Automotive Sensor Interfaces
The 125°C rating and 20MHz speed allow reliable reading of engine or exhaust sensors.
Industrial Valve Controllers
PWM outputs and 32KB flash manage proportional valves in hydraulic systems.
High-Temperature LED Drivers
Wide voltage range and PWM support constant-current control in outdoor lighting.
Power Tool Electronics
Robust BOD/WDT and high temp tolerance suit drill or impact driver control boards.
Smart Battery Packs
3KB RAM enables state-of-charge algorithms for lithium-ion battery management.
Agricultural Equipment
Dust-resistant SOIC package and wide temp range fit tractor or harvester modules.
