The Microchip ATSAM4LS2BA-MUR is an ultra-low-power 32-bit MCU built on the ARM Cortex-M4 core. Operating at 48MHz with a supply range of 1.68V to 3.6V, it balances performance and energy efficiency for battery-operated applications. It features 128KB flash, 32KB RAM, and a rich peripheral set including I2S, DMA, PWM, and multiple serial interfaces. The 64-VFQFN package makes it a compact choice for IoT, medical, and audio devices.
- Ultra-Low Power Consumption: The Cortex-M4 core with sleep modes and 1.68V operation extends battery life in portable devices.
- Integrated I2S for Audio: Direct interface to audio codecs simplifies hardware design and reduces BOM cost.
- High Memory Density: 128KB flash and 32KB RAM support complex applications without external memory.
- DMA Efficiency: Peripheral-to-memory transfers reduce CPU load, enabling more time in low-power states.
IoT Sensor Nodes
The ultra-low-power Cortex-M4 core with 1.68V operation enables years of battery life in wireless sensors collecting temperature, humidity, or pressure data.
Portable Medical Devices
With 32KB RAM and DMA, it can process biometric signals (ECG/EEG) in real time while maintaining low power consumption for wearable monitors.
Audio Processing
The integrated I2S interface and DSP instructions allow implementation of voice triggers, noise cancellation, and audio playback in smart speakers or hearing aids.
Industrial Data Loggers
Its wide voltage range and robust peripherals (PWM, WDT) make it reliable for logging vibration or temperature data in factory automation equipment.
Smart Home Controllers
The 128KB flash supports complex communication stacks (Zigbee, Thread) while the DMA handles sensor polling, reducing CPU wake-up time.
Battery Management Systems
Multiple ADC channels and brown-out detection enable accurate cell voltage monitoring and protection in portable power tools.
