The Microchip ATTINY826-MU is a high-performance 8-bit AVR microcontroller in a compact 20-VFQFN package. It delivers 8KB of Flash and 1KB of SRAM, operating at up to 20MHz with a supply range of 1.8V to 5.5V. This MCU integrates essential peripherals like PWM, brown-out detection, and a watchdog timer, making it a reliable choice for cost-sensitive embedded control applications.
- Low-voltage operation (1.8V): Extends battery life in portable devices by allowing direct operation from a single-cell battery.
- 20MHz AVR core: Provides fast, deterministic processing for real-time control tasks without needing an external oscillator.
- Compact 20-VFQFN package: Saves PCB space and improves thermal performance through the exposed pad, ideal for miniaturized designs.
- Integrated safety features: Brown-out reset and watchdog timer prevent system lockups in noisy or unstable power environments.
Battery-Powered IoT Sensors
The 1.8V minimum supply and low-power sleep modes enable long battery life in wireless sensor nodes. The 20MHz AVR core efficiently processes sensor data before transmission.
Motor Control for Small Appliances
With PWM channels and a 20MHz clock, the ATTINY826-MU can generate precise control signals for brushless DC or stepper motors in compact appliances, while the brown-out detector ensures safe operation.
LED Lighting and Dimming Systems
Its PWM outputs and 12-bit ADC allow for smooth, high-resolution dimming control and color mixing in LED drivers, with the exposed pad aiding thermal dissipation.
Portable Medical Devices
The wide voltage range and small 20-VFQFN package make it suitable for wearable monitors. The WDT and POR features enhance system reliability in critical health tracking.
Industrial Sensor Conditioning
In 4-20mA loops or industrial transmitters, the integrated analog comparator and ADC can condition signals from thermocouples or strain gauges, while the -40°C to 85°C range covers most factory environments.
Automotive Body Electronics (Non-Critical)
For interior lighting or window control modules, the 5.5V max supply and robust reset circuitry provide dependable operation in 12V automotive systems with proper regulation.
