ATSAM4LC2CA-CFUR

Overview

The ATSAM4LC2CA-CFUR is a 32-bit microcontroller based on the ARM Cortex-M4 processor, operating at frequencies up to 48MHz. It features 128KB of embedded Flash memory and 32KB of SRAM. The device supports a single power supply ranging from 1.68V to 3.6V and operates within a temperature range of -40°C to +85°C. Connectivity includes USB 2.0 Device and Embedded Host capabilities, alongside standard serial interfaces such as USART, SPI, and I2C.

Feature Summary

Integrates picoPower technology for ultra-low power consumption with configurable voltage scaling.
Includes an LCD controller supporting segment displays and capacitive touch sensing modules.
Features hardware security acceleration via an Advanced Encryption System (AES) module.
Supports direct peripheral-to-peripheral communication through the Peripheral Event System.

Applications

Battery-powered wearable devices requiring low active current
Industrial controllers utilizing segment LCD displays
Secure data logging applications with encryption requirements
USB-enabled consumer electronics with host functionality

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure the selected variant matches the required pin count and peripheral availability for the target design. Cross-reference the datasheet revision date to confirm compatibility with existing firmware libraries.

Selection Notes

Select this component when application requirements include both USB host/device capabilities and integrated display driving. The SAM4LC sub-series provides necessary cryptographic hardware for secure environments. Evaluate memory constraints against the 128KB Flash limit before finalizing the part number choice.

Part Context

This microcontroller belongs to the SAM4L series, designed for low-power applications. The LC sub-series specifically differentiates itself by including AES security modules and LCD controllers, unlike the LS sub-series which lacks these features but retains USB host capability.
