ATSAM4LC2BA-UUR

Overview

The ATSAM4LC2BA-UUR is a microcontroller from the SAM4L series, featuring an ARM Cortex-M4 core operating at up to 48MHz. It includes 128KB of embedded Flash and 32KB of SRAM. The device supports USB 2.0 Device and Embedded Host modes with an on-chip transceiver. Key peripherals include a segment LCD controller, AESA for encryption, capacitive touch module (CATB), and various communication interfaces like USART, SPI, and TWI.

Feature Summary

• Integrates picoPower technology for ultra-low power consumption across multiple sleep modes.
• Includes a dedicated segment LCD controller for passive displays.
• Features hardware cryptographic acceleration via the Advanced Encryption System (AESA).
• Supports direct peripheral-to-peripheral communication through the Peripheral Event System.

Applications

• Battery-powered wearable devices requiring low power consumption.
• Industrial control systems utilizing encrypted data transmission.
• Smart home appliances with capacitive touch user interfaces.
• Portable medical equipment needing secure data handling.

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 selected package variant. Confirm that the component meets all required environmental standards for the intended application environment.

Selection Notes

Select this model when both LCD display capabilities and USB host functionality are required alongside low power operation. Consider the 128KB Flash size for firmware requirements. Evaluate the pin count to ensure sufficient I/O availability for the system design without unnecessary complexity.

Part Context

This part belongs to the ATSAM4LC sub-series within the broader SAM4L family. It is distinguished by its inclusion of the LCD controller and AESA module, which are absent in the LS sub-series. The UUR suffix typically denotes a specific tape and reel packaging option for automated assembly.
