The Microchip ATSAM4LS2CA-AU is a low-power ARM Cortex-M4 MCU with 128KB flash and 32KB RAM. Operating at 48MHz from 1.68V to 3.6V, it includes DMA, I2S, PWM, and safety features. The 100-TQFP package is suited for audio, IoT, and industrial applications where LCD is not required.
- Cost-optimized: Removes LCD controller to reduce price while keeping core performance.
- Low-power operation: 1.68V minimum and efficient Cortex-M4 extend battery life.
- Audio-ready: I2S and DMA simplify digital audio streaming.
- Scalable family: Pin-compatible with SAM4L series for design flexibility.
Wireless Sensor Networks
The low 1.68V operation and 48MHz Cortex-M4 enable edge processing in battery-powered nodes, reducing radio transmission time.
Audio Effects Pedals
I2S and DMA stream audio data to codecs, while the Cortex-M4 runs DSP effects like reverb in real time.
Portable Instrumentation
32KB RAM buffers high-speed ADC readings, and the 100-TQFP package allows compact multimeter designs.
Smart Grid Monitors
With PWM and WDT, this MCU manages power quality analysis in energy meters, operating from 3.3V supplies.
