The Microchip ATTINY3226-SFR is a low-power 8-bit AVR microcontroller in a 20-pin SOIC package. It operates from 1.8V to 5.5V at up to 20MHz, with 32KB flash and 3KB SRAM. Integrated PWM, Brown-out Reset, Power-on Reset, and Watchdog Timer make it a versatile choice for compact, energy-efficient designs.
- High flash density (32KB) – fits complex applications in a small package.
- Low voltage operation (1.8V) – ideal for single-cell battery devices.
- PWM integrated – reduces external components for analog control.
- Wide temperature range – reliable in automotive and outdoor settings.
Consumer Electronics
Control RGB LEDs with PWM in gaming peripherals or smart bulbs, using the 3KB SRAM for color transition effects.
Battery-Powered Toys
With 1.8V minimum supply, it can run directly from two AA batteries, driving motors and sound modules.
Sensor Hubs
Aggregate data from multiple I2C sensors and process with the 20MHz AVR core, then output via UART to a host.
Automotive Accessories
Handle window tint control or mirror adjustment with PWM, rated for -40°C to 125°C under the hood.
Smart Agriculture
Monitor soil moisture and control irrigation valves with low-power sleep modes, ideal for solar-powered nodes.
Medical Disposables
Implement single-use diagnostic devices with simple logic and PWM for actuator control, keeping cost low.
