The ATSAMD21G16B-AFT is a 32-bit ARM Cortex-M0+ microcontroller from Microchip, engineered for extended temperature applications. It operates at 48MHz with 64KB flash and 8KB SRAM in a 48-TQFP package. Supporting 1.62V to 3.6V, it includes DMA, I2S, PWM, and brown-out detection, making it ideal for automotive and industrial control systems requiring -40°C to 125°C reliability.
- Extended temperature: -40°C to 125°C enables use in engine bays and industrial ovens.
- Large RAM: 8KB SRAM supports complex data buffering and multitasking.
- Low voltage operation: 1.62V minimum allows direct battery operation.
- Rich peripherals: I2S and DMA simplify audio and high-speed data acquisition.
Automotive Engine Control Sensors
The -40°C to 125°C range and 48MHz performance handle real-time sensor fusion for pressure and temperature monitoring.
Industrial Motor Drives
PWM and DMA generate precise waveforms for 3-phase BLDC motors, with WDT for fault detection.
Smart Grid Monitoring
8KB RAM buffers power quality data, while I2S interfaces with external ADCs for high-resolution sampling.
Medical Wearables
Low 1.62V operation and small footprint enable continuous glucose monitors or ECG patches with long battery life.
Robotics Controllers
Multiple PWM channels and DMA coordinate servo motors, while POR ensures clean startup.
IoT Edge Gateways
With 64KB flash, it runs lightweight protocols (MQTT) and interfaces with sensors via I2C/SPI.
