Overview
The ATSAM4LC8BA-AU is a 32-bit microcontroller based on the ARM Cortex-M4 core, operating at frequencies up to 48MHz. It features 512KB of embedded Flash memory and 64KB of SRAM. The device supports a single power supply ranging from 1.68V to 3.6V and includes an integrated LCD controller for segment displays. Connectivity options include USB 2.0 Device and Embedded Host, USART, SPI, TWI, and I2S. Security is provided by a 128-bit AES module.
Feature Summary
- Integrates picoPower technology for ultra-low active current consumption with configurable voltage scaling.
- Includes a dedicated Liquid Crystal Display (LCD) controller supporting passive displays with up to 40 segments and 4 commons.
- Features an Advanced Encryption System (AES) module compliant with FIPS Publication 197 for data security.
- Supports direct peripheral-to-peripheral communication via the Peripheral Event System without CPU intervention.
Applications
- Battery-powered devices requiring low standby current
- Applications utilizing monochrome passive LCD interfaces
- Systems requiring hardware-accelerated encryption
- Audio processing using bitstream DAC or I2S controllers
Procurement Notes
Verify the specific package type against your design requirements, as the SAM4L family utilizes multiple form factors including TQFP, QFN, and WLCSP. Confirm that the ordering suffix corresponds to the intended pin count and package style. Ensure compatibility with the required operating temperature range and voltage specifications before finalizing procurement.
Selection Notes
Select this component when both LCD driving capabilities and cryptographic functions are necessary within a low-power constraint. Compare against the ATSAM4LS series if USB host functionality is not required. Evaluate the available GPIO count and peripheral channels to ensure sufficient resources for the target application's interface needs.
Part Context
This part belongs to the Microchip SAM4L series, designed for low-power applications. The 'C' designation indicates inclusion of the LCD controller and AES security module, distinguishing it from the 'S' variant which lacks these features but retains full-speed USB host capability.
