The Microchip ATTINY3224-SSU is a versatile 8-bit AVR microcontroller with 32KB flash and 3KB SRAM in a 14-pin SOIC package. It operates from 1.8V to 5.5V and runs at up to 20MHz, offering ample performance for mid-range embedded tasks. Integrated brown-out detection, power-on reset, PWM, and watchdog timer ensure dependable operation in industrial and consumer environments from -40°C to 85°C.
- Large memory (32KB flash): Supports complex applications without external storage.
- 3KB SRAM: Enables buffering and data processing for sensor fusion.
- Wide voltage range: Flexible power supply options from batteries or regulated rails.
- Compact SOIC-14: Reduces board space while maintaining 20MHz performance.
- Robust protection: BOD, POR, and WDT prevent system lockups.
Smart Home Controllers
32KB flash allows complex firmware for lighting scenes or thermostat algorithms, while PWM drives dimmers and valves.
Industrial Sensor Hubs
Multiple GPIOs and 3KB RAM enable aggregation of temperature, pressure, and flow sensors in factory automation.
Consumer IoT Devices
Low power consumption and 1.8V operation support always-on edge nodes in smart plugs or environmental monitors.
Motor Control for Drones
High-speed PWM and 20MHz processing provide precise ESC (electronic speed controller) signals for small brushless motors.
Portable Instrumentation
The SOIC-14 package and wide voltage range fit handheld multimeters or data loggers.
Automotive Body Electronics
With BOD and WDT, it reliably manages window lift or mirror adjustment modules in vehicles.
