Overview
The ATSAM4LS2CA-CFU is a 32-bit microcontroller based on the ARM Cortex-M4 core, operating at a maximum frequency of 48 MHz. It features 128 KB of embedded Flash memory and 32 KB of SRAM. The device includes a 16-channel 12-bit ADC and a 10-bit DAC. Connectivity options include USB 2.0 Device/Host, SPI, I2C, UART/USART, and LINbus. It operates within a voltage range of 1.62 V to 3.6 V and supports an industrial temperature range of -40°C to +85°C in a QFN-100 package.
Feature Summary
- Integrates ARM Cortex-M4 processor with picoPower technology for ultra-low power consumption.
- Includes advanced security peripherals such as AES encryption and True Random Number Generator (TRNG).
- Features a Peripheral Event System enabling direct peripheral-to-peripheral communication without CPU intervention.
- Supports multiple low-power modes including idle and standby for extended battery life.
Applications
- Battery-powered portable devices requiring low power consumption.
- Industrial control systems utilizing LINbus or I2C interfaces.
- USB-enabled consumer electronics and human interface devices.
- Smart home appliances with capacitive touch sensing capabilities.
Procurement Notes
Verify the specific suffix CFU corresponds to the QFN-100 package and industrial temperature grade when sourcing. Confirm RoHS compliance status through official Microchip documentation prior to integration. Ensure supply chain authenticity by purchasing from authorized distributors only. Check for any recent errata sheets related to silicon revisions that may impact design implementation.
Selection Notes
Select this component for designs requiring a balance of processing performance and energy efficiency. The integrated USB controller and extensive analog peripherals make it suitable for sensor-rich applications. Consider the 100-pin QFN package constraints for PCB layout. Evaluate if the 48 MHz clock speed meets real-time processing requirements compared to higher-speed SAM4S variants.
Part Context
This part belongs to the Atmel SAM4L series, designed specifically for low-power applications. The SAM4L family utilizes the Cortex-M4 core optimized for picoPower operation. It distinguishes itself from the high-performance SAM4S series by prioritizing energy efficiency over raw clock speed. The series supports various connectivity options essential for modern embedded systems.
Replacement Considerations
ATSAM4LS2BA-AU offers similar specifications in a TQFP-64 package. ATSAMD20J18 provides a Cortex-M0+ alternative with lower performance but potentially lower cost. Verify pin compatibility and software library support before substituting with other SAM4L variants or different Microchip families.
