The Microchip ATSAM4LS4AA-MUR is a low-power 32-bit microcontroller built on the ARM Cortex-M4 architecture. It delivers 48MHz performance with 256KB flash and 32KB RAM. Its 1.68V to 3.6V supply range and integrated peripherals like I2S, DMA, and PWM make it suitable for portable and industrial applications.
- Ultra-low power consumption: 1.68V minimum supply extends battery life in portable designs.
- High-performance Cortex-M4 core: 48MHz with DSP instructions for efficient signal processing.
- Rich peripheral set: I2S, DMA, PWM, and WDT reduce external component count.
- Compact 48-VFQFN package: Saves PCB space for space-constrained designs.
Low-Power IoT Sensor Nodes
The 1.68V minimum supply and multiple low-power modes make it ideal for battery-powered sensors that need to run for years on a coin cell.
Portable Medical Devices
The Cortex-M4 core with DSP instructions handles biosignal processing (ECG, PPG) efficiently while the DMA controller offloads data transfer from the CPU.
Audio Processing and Playback
The integrated I2S interface enables direct connection to audio codecs for voice prompts or audio recording in consumer devices.
Industrial Control Panels
With PWM, WDT, and brown-out detection, it can manage simple motor control or actuator timing in industrial environments up to 85°C.
Smart Home Controllers
Its rich peripheral set (DMA, POR, PWM) supports multiple sensor inputs and output control in a compact 48-pin package.
Wearable Fitness Trackers
The low voltage operation and small footprint allow for compact PCB designs in wrist-worn devices.
