The Microchip ATTINY841-SSU is a high-performance 8-bit AVR microcontroller in a compact 14-pin SOIC package. It delivers 8KB of flash memory and 512 bytes of SRAM, operating at speeds up to 16MHz. With a supply voltage range of 1.7V to 5.5V, it is engineered for low-power and portable applications. Its integrated PWM channels and rich peripheral set make it a versatile choice for embedded control tasks.
- Ultra-Low Voltage Operation: Starts at 1.7V, enabling direct battery operation without boost converters.
- High-Speed AVR Core: 16MHz throughput for responsive real-time control.
- Integrated PWM: Simplifies motor and lighting control without external timers.
- Compact SOIC-14 Package: Saves board space for space-constrained designs.
Battery-Powered Sensor Nodes
With a 1.7V minimum supply voltage and low-power AVR core, the ATTINY841-SSU can run directly from a single alkaline cell, reducing system complexity and extending battery life in IoT sensors.
PWM LED Dimming
The integrated PWM channels allow precise brightness control for LED lighting systems. The 16MHz clock speed ensures smooth, flicker-free dimming at high frequencies.
Compact Motor Control
Its 8KB flash and 512 bytes of RAM are sufficient for simple brushless DC motor commutation logic, while the PWM outputs drive the gate driver circuitry directly.
Portable Medical Devices
The wide voltage range and small SOIC footprint make it ideal for wearable health monitors that need to operate reliably across varying battery states.
Industrial Sensor Interfaces
The 14-pin package provides enough I/O for reading analog sensors and communicating over I2C or SPI to a host controller, all within a -40°C to 85°C range.
