The Microchip ATSAM4LS8BA-MUR is a low-power ARM Cortex-M4 microcontroller with 512KB flash and 64KB RAM. Operating from 1.68V to 3.6V at 48MHz, it integrates DMA, I2S, PWM, and brown-out detection in a compact 64-VFQFN package, ideal for portable and industrial embedded designs.
- Ultra-low voltage operation (1.68V) – enables direct battery operation without boost converters, reducing BOM cost.
- 512KB flash with DMA – supports large application code and efficient peripheral-to-memory transfers without CPU loading.
- I2S audio interface – simplifies digital audio connectivity for voice and sound applications.
- Industrial temperature range (-40°C to 85°C) – ensures reliability in harsh environments.
Low-Power Sensor Nodes
The 1.68V minimum supply and 48MHz Cortex-M4 enable battery-powered sensor hubs with efficient DSP for signal conditioning.
Portable Medical Devices
With 512KB flash and I2S audio interface, it supports glucose meters and pulse oximeters requiring data logging and audio alerts.
Industrial IoT Gateways
DMA and PWM peripherals allow real-time motor control and sensor aggregation in 24V industrial environments with external level shifting.
Audio Processing Modules
The I2S peripheral and Cortex-M4 DSP instructions handle audio codec interfacing for voice-controlled smart home devices.
Wearable Fitness Trackers
Low quiescent current and brown-out detection ensure reliable operation in compact 64-VFQFN packages for step counting and heart-rate monitoring.
Smart Metering Systems
Multiple PWM channels and WDT provide robust control for electricity metering with tamper detection and periodic data transmission.
