The Microchip ATSAM3SD8CA-AUR is an ARM Cortex-M3 MCU operating at 64MHz. It offers 512KB flash and 64KB SRAM, with an integrated I2S for audio applications. Its 1.62V-3.6V supply range and 100-LQFP package make it a robust choice for industrial and portable designs.

  • Large memory: 512KB flash supports complex applications and OTA updates.
  • Audio-ready: I2S peripheral simplifies digital audio integration.
  • Low-power operation: 1.62V minimum voltage reduces energy consumption.
  • DMA efficiency: Offloads data movement for better real-time performance.

Audio Processing

Integrated I2S interface enables direct connection to audio codecs for voice recognition.

Industrial Data Loggers

512KB flash and DMA allow high-capacity logging with minimal CPU overhead.

Portable Instrumentation

Low 1.62V operation extends battery life in handheld multimeters.

Smart Building Controllers

Multiple PWM channels drive LED lighting and HVAC actuators.

Medical Wearables

Compact 100-LQFP and -40°C to 85°C range suit wearable health monitors.

Communication Gateways

Rich serial peripherals (UART, SPI, I2C) enable protocol bridging.
