ATSAM4LS2BA-MUR

Overview

The ATSAM4LS2BA-MUR is a microcontroller from the Microchip SAM4L series, featuring a 32-bit ARM Cortex-M4 processor running at up to 48MHz. It integrates 128KB of embedded Flash and 32KB of SRAM within a 64-lead QFN package. The device supports USB 2.0 Device functionality, includes a capacitive touch module, and offers ultra-low power consumption via picoPower technology.

Feature Summary

• Integrates an ARM Cortex-M4 core with Memory Protection Unit (MPU) for secure operation.
• Features picoPower technology enabling active current consumption down to 90 μA/MHz.
• Includes a low-power capacitive touch module supporting up to 32 sensors.
• Supports direct peripheral-to-peripheral communication via the Peripheral Event System.

Applications

• Battery-powered wearable devices
• Industrial sensor nodes
• Smart home appliances

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with required operating temperature ranges and voltage specifications before finalizing procurement decisions.

Selection Notes

Select this component when a balance of moderate memory capacity and ultra-low power performance is required. Consider the absence of LCD controller and AES hardware compared to other SAM4L variants if those features are necessary for the application.

Part Context

This part belongs to the SAM4L family, designed for applications requiring high efficiency and extended battery life. It shares architectural similarities with the SAM4S series but focuses on lower power modes and integrated touch capabilities.
