Overview
The ATSAM4LS2CA-CFU is a 32-bit microcontroller based on the ARM Cortex-M4 processor, operating at frequencies up to 48MHz. It features picoPower technology for ultra-low power consumption, with active current down to 90 µA/MHz. The device includes 128KB of embedded Flash memory and 32KB of SRAM. It supports a single 1.68V to 3.6V power supply and offers various peripherals including USB 2.0 Device, USART, SPI, TWI, ADC, DAC, and capacitive touch modules.
Feature Summary
- Integrates picoPower technology for ultra-low power consumption across multiple sleep modes.
- Includes an ARM Cortex-M4 core with Memory Protection Unit (MPU) and Thumb-2 instruction set.
- Features a comprehensive peripheral set including USB 2.0 Device, LCD controller, and capacitive touch module.
- Supports direct peripheral-to-peripheral communication via Peripheral Event System and DMA.
Applications
- Battery-powered consumer electronics requiring extended operational life
- Industrial control systems needing robust real-time processing capabilities
- Wearable devices utilizing capacitive touch interfaces
- Smart home automation controllers with low standby power requirements
Procurement Notes
Verify component authenticity through authorized Microchip Technology distributors or certified suppliers. Confirm package integrity and absence of physical damage upon receipt. Ensure storage conditions comply with moisture sensitivity level requirements to prevent soldering defects during assembly processes.
Selection Notes
Select this model when application demands balance between moderate code size and minimal power usage. Suitable for designs where USB connectivity is required without host functionality. Consider pin count constraints as the 100-pin variant provides extensive I/O options compared to smaller packages in the SAM4L family.
Part Context
Part of the SAM4L series designed for low-power applications. Shares architectural similarities with SAM4LC but lacks AESA and segment LCD support. Offers cost-effective solution for embedded systems prioritizing energy efficiency over cryptographic hardware acceleration or complex display driving capabilities.
Replacement Considerations
ATSAM4LS2BA-AU: Different package type (TQFP vs VFBGA). ATSAM4LS4CA-AU: Higher memory capacity (256KB Flash). Verify pin compatibility and software configuration adjustments before substitution.
