The Microchip ATSAM3N0BA-MUR is a 32-bit ARM Cortex-M3 microcontroller optimized for low-power embedded control. It delivers 48MHz performance with 32KB flash and 8KB SRAM in a compact 64-VFQFN package. Its 1.62V to 3.6V supply range and integrated DMA, PWM, and watchdog timer make it ideal for portable and industrial applications.
- Ultra-low voltage operation: Down to 1.62V enables direct battery operation without boost converters.
- Efficient DMA engine: Reduces CPU load during peripheral-to-memory transfers, saving power.
- Compact 64-VFQFN package: Saves PCB space for space-constrained designs.
- Robust reset management: POR and brown-out detect ensure reliable startup and shutdown.
Industrial Sensor Nodes
The 1.62V minimum supply and low-power Cortex-M3 core enable battery-operated industrial sensors that must run for years on coin cells.
Portable Medical Monitors
With 32KB flash and 8KB RAM, it can handle basic signal processing for glucose meters or pulse oximeters while maintaining a small 64-VFQFN footprint.
Motor Control Hubs
The PWM channels and DMA allow precise generation of control signals for small DC or stepper motors in robotics.
Smart Home Controllers
Its wide voltage range (1.62V-3.6V) makes it easy to interface with both 2V and 3.3V logic peripherals in smart lighting or thermostat systems.
Data Logging Devices
The brown-out detect and watchdog timer ensure reliable operation in remote logging equipment where power fluctuations are common.
Automotive Body Electronics
Operating from -40°C to 85°C, it suits non-critical automotive modules like window lift controllers or mirror adjusters.
