ATSAM4LS4BA-MUR

Overview

The ATSAM4LS4BA-MUR is a 32-bit microcontroller based on the ARM Cortex-M4 core, operating at frequencies up to 48MHz. It features 256KB of embedded Flash memory and 32KB of SRAM. The device supports a single power supply ranging from 1.68V to 3.6V. Key peripherals include USB 2.0 Device and Embedded Host capabilities, a 16-channel 12-bit ADC, a 10-bit DAC, and multiple communication interfaces such as USART, SPI, and TWI. It incorporates picoPower technology for ultra-low power consumption.

Feature Summary

Integrates picoPower technology for ultra-low active current consumption with configurable voltage scaling.
Includes an Advanced Encryption System (AES) module supporting 128-bit key lengths for data security.
Features a Peripheral Event System allowing direct peripheral-to-peripheral communication without CPU intervention.
Supports SleepWalking functionality to enable selective module activation based on peripheral events in sleep modes.

Applications

Low-power wearable devices requiring extended battery life
USB-enabled consumer electronics with host capabilities
Industrial control systems utilizing secure communication protocols
Battery-operated sensor nodes with capacitive touch interfaces

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with existing PCB footprints for the QFN or WLCSP variant specified. Confirm that the selected revision matches the required firmware development environment and toolchain support.

Selection Notes

Select this component when application requirements demand a balance between high-performance processing and minimal power usage. The inclusion of USB Host functionality distinguishes it from device-only variants. Consider the available GPIO count and peripheral set relative to system connectivity needs before finalizing the design.

Part Context

This part belongs to the SAM4L series, designed specifically for low-power applications. It shares the same core architecture as other SAM4L variants but differs in memory size and peripheral availability. The series emphasizes energy efficiency through advanced power management modes and hardware-accelerated cryptographic functions.
