The ATSAM3N1CB-AU from Atmel is a 32-bit MCU based on the ARM Cortex-M3 core. It operates at 48MHz with 64KB flash and 8KB RAM. Supporting 1.62V to 3.6V, it includes DMA, PWM, WDT, and brown-out detection in a 100-LQFP package, offering a rich peripheral set for mid-range embedded applications.
- ARM Cortex-M3 core: High-performance 32-bit processing with hardware divide and Thumb-2 instructions for dense code.
- 100-pin LQFP: Provides up to 80+ I/O pins for complex interface requirements.
- Low voltage operation (1.62V): Enables direct battery operation and energy-efficient designs.
- Integrated DMA and PWM: Offloads CPU and enables precise timing for motor or power control.
Building Automation Controllers
The 100-pin package provides ample GPIO for multiple sensor inputs and relay outputs in HVAC or lighting control systems.
Industrial Process Monitors
48MHz Cortex-M3 with DMA handles high-speed ADC sampling for pressure and flow transmitters in process control.
Medical Diagnostic Equipment
64KB flash stores calibration curves, while the 1.62V minimum supply enables battery backup for portable analyzers.
Robotics Control Boards
Multiple PWM channels and WDT support servo control and safety monitoring in educational or hobby robots.
Smart Grid Meters
The Cortex-M3 core efficiently computes power quality metrics, and the wide voltage range tolerates supply fluctuations.
