ATSAM4LC8BA-MU

Overview

The ATSAM4LC8BA-MU is a 32-bit ARM Cortex-M4 microcontroller from the SAM4L series, operating at up to 48MHz. It features 512KB of embedded Flash and 64KB of SRAM within a 64-lead QFN package. The device integrates picoPower technology for ultra-low power consumption, including active mode down to 90µA/MHz. Key peripherals include a segment LCD controller, USB device and host interface, 128-bit AES encryption, capacitive touch module, and various communication interfaces such as USART, SPI, and I2C.

Feature Summary

• Integrates picoPower technology for ultra-low power consumption with configurable voltage scaling.
• Includes an on-chip segment LCD controller supporting passive displays with integrated buffers.
• Features hardware cryptographic acceleration via a 128-bit Advanced Encryption System (AES) module.
• Supports direct peripheral-to-peripheral communication through the Peripheral Event System.

Applications

• Battery-powered portable devices requiring extended operational life
• Applications utilizing monochrome passive liquid crystal displays
• Secure data transmission systems requiring hardware-based encryption
• User interface modules incorporating capacitive touch controls

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with required development tools and software frameworks before procurement. Confirm RoHS compliance status if mandated by project specifications.

Selection Notes

Select this component when low power consumption is critical alongside moderate processing performance. The inclusion of an LCD controller and AES module makes it suitable for secure display applications. Evaluate pin count requirements against the 64-lead QFN package availability.

Part Context

This part belongs to the SAM4L family, designed for low-power applications using the ARM Cortex-M4 core. The 'LC' designation indicates the inclusion of the LCD controller and AES security features, distinguishing it from the LS sub-series which lacks these specific peripherals.

Replacement Considerations

ATSAM4LC8CA-AU: Same memory and core but in a 100-TQFP package. ATSAM4LS8BA-MU: Similar performance but lacks the LCD controller and AES module.
