The ATSAM3N0BA-AUR is a 32-bit ARM Cortex-M3 microcontroller from Microchip, offering 32KB flash and 8KB SRAM. It runs at 48MHz and supports a wide voltage range of 1.62V to 3.6V. Housed in a 64-LQFP package, it integrates DMA, PWM, and brown-out detection for robust embedded applications.
- Larger memory (32KB flash) – supports more complex firmware than smaller variants.
- Wide voltage range – flexible power supply design.
- DMA controller – improves peripheral throughput without CPU intervention.
- Industrial temperature grade – reliable in harsh environments.
Smart Meters
The 32KB flash and 8KB RAM provide enough space for metering algorithms, while the 48MHz Cortex-M3 handles communication protocols.
Automotive Body Electronics
With a -40°C to 85°C range and robust POR, it suits window lift or mirror control modules.
Building Automation
DMA and PWM enable efficient control of HVAC actuators and lighting dimmers.
Consumer Robotics
The 64-pin package allows interfacing with multiple sensors and motor drivers for small educational robots.
Point-of-Sale Terminals
Its low power and security features (brown-out reset) support reliable transaction processing.
Wireless Sensor Networks
Combined with an external RF transceiver, the MCU manages sleep/wake cycles efficiently.
