The ATSAM3N0BA-AU from Microchip is a 48MHz ARM Cortex-M3 MCU with 32KB flash and 8KB RAM. It operates from 1.62V to 3.6V in a 64-LQFP package, integrating DMA, PWM, POR, BOD, and WDT for reliable embedded control.
- Ultra-low voltage operation: 1.62V enables direct battery operation with minimal power loss.
- Efficient Cortex-M3 core: 48MHz provides ample performance for mid-range applications.
- Rich peripheral set: DMA and PWM reduce CPU overhead for real-time tasks.
- Industrial temperature range: -40°C to 85°C suits factory and outdoor environments.
Portable Instrumentation
1.62V operation and 48MHz Cortex-M3 enable handheld multimeters with high-resolution ADC sampling.
Building Automation
DMA and PWM support HVAC damper control and lighting dimming with smooth analog output.
Consumer Wearables
Low voltage and small 64-LQFP package fit fitness trackers with sensor fusion and BLE protocol handling.
Motor Control
PWM timers with dead-time generation drive BLDC motors in drones and power tools.
Data Loggers
8KB RAM buffers sensor data before writing to external flash, while WDT ensures long-term reliability.
Security Panels
Robust BOR and POR maintain system integrity during power fluctuations in access control systems.
