The ATSAM4LS8BA-MU from Microchip Technology is a low-power ARM Cortex-M4 microcontroller running at 48MHz. It features 512KB flash and 64KB RAM, with a supply range of 1.68V to 3.6V. The 64-pin VFQFN package integrates I2S, DMA, PWM, and brown-out detection, making it suitable for IoT, audio, and portable applications.
- High-performance Cortex-M4: 48MHz with DSP instructions accelerates signal processing tasks.
- Large memory capacity: 512KB flash and 64KB RAM support complex applications and data logging.
- Ultra-low voltage operation: 1.68V minimum enables direct battery operation without boost converters.
- Rich peripheral set: I2S, DMA, and PWM reduce external component count.
IoT Edge Nodes
The Cortex-M4 at 48MHz with 512KB flash runs MQTT stacks and sensor fusion, while 1.68V operation extends coin-cell battery life.
Audio Processing Units
The integrated I2S interface streams digital audio to codecs, and DMA handles buffer transfers without CPU overhead.
Wearable Health Monitors
Low-voltage operation and 64KB RAM support real-time ECG filtering and heart-rate algorithms in compact 64-VFQFN packages.
Smart Home Hubs
PWM outputs control dimmable LED lighting, while the -40°C to 85°C range suits wall-mounted installations.
Portable Instrumentation
The 512KB flash stores calibration tables and logging buffers, with DMA enabling continuous ADC sampling for multimeters.
Industrial Sensor Bridges
Brown-out reset and WDT ensure reliable operation in 3.3V industrial sensor networks with noisy power lines.
