Overview
The ATSAM4LS8BA-MUR is a microcontroller from the Microchip SAM4L series, featuring an ARM Cortex-M4 core running at up to 48MHz. It includes 512KB of embedded Flash and 64KB of SRAM. The device supports USB 2.0 Device functionality, four USARTs, one SPI, four TWI interfaces, and a 16-channel 12-bit ADC. It utilizes picoPower technology for ultra-low power consumption across various sleep modes.
Feature Summary
- Integrates picoPower technology for optimized active current consumption and multiple low-power operating modes.
- Includes a full-speed USB 2.0 device interface with an on-chip transceiver and up to eight bidirectional endpoints.
- Features a capacitive touch module supporting autonomous detection for up to 32 sensors.
- Provides direct peripheral-to-peripheral communication capabilities via the Peripheral Event System.
Applications
- Battery-powered wearable devices requiring extended operational life
- USB-enabled consumer electronics and peripherals
- Industrial control systems utilizing capacitive touch interfaces
- Low-power sensor nodes with event-driven processing requirements
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required voltage levels and temperature ranges for the target application environment before finalizing procurement decisions.
Selection Notes
Select this component when a balance of moderate memory capacity and ultra-low power performance is required. The SAM4LS variant is suitable for applications needing USB device connectivity without the cryptographic features or LCD controllers found in other sub-series variants.
Part Context
This part belongs to the SAM4L family, which targets low-power applications. It shares the same core architecture as the SAM4LC but lacks the segment LCD controller and AES security module. It offers a cost-effective solution for designs prioritizing power efficiency and basic connectivity over advanced display or encryption features.
Replacement Considerations
Consult official substitution guides for pin-compatible alternatives within the SAM4L family. Verify that any replacement maintains the required Flash size, SRAM capacity, and peripheral availability for the specific design constraints.
