The Microchip ATSAM4LS2AA-MUR is a low-power ARM Cortex-M4 microcontroller in a 48-VFQFN package. It operates from 1.68V to 3.6V at 48MHz, with 128KB flash and 32KB RAM. Integrated DMA, I2S, POR, PWM, and WDT make it suitable for battery-powered and audio applications.
- Ultra-low voltage (1.68V) extends battery life in portable devices.
- Cortex-M4 core with DSP instructions accelerates signal processing.
- DMA and I2S enable high-throughput audio without CPU load.
- Exposed pad package improves thermal dissipation for compact designs.
Wearable Health Trackers
The 1.68V minimum supply and 48MHz Cortex-M4 enable continuous sensor fusion with low power consumption.
Portable Audio Recorders
I2S interface connects directly to codecs, while DMA offloads data transfer from the CPU for glitch-free recording.
IoT Edge Nodes
With 128KB flash and 32KB RAM, it runs MQTT stacks and encryption algorithms for secure cloud communication.
Smart Metering Systems
The 3.6V max supply works with Li-ion batteries, and the PWM outputs drive metering pulse LEDs.
Medical Infusion Pumps
Brown-out detection and WDT ensure fail-safe operation, while the Cortex-M4 handles complex dosing algorithms.
Industrial Data Loggers
DMA channels capture ADC data at high rates without CPU intervention, storing logs in the 32KB RAM.
