Overview
The ATSAM4LC4BA-UUR is a 32-bit microcontroller based on the ARM Cortex-M4 core, operating at frequencies up to 48MHz. It features 256KB of embedded Flash memory and 32KB of SRAM. The device supports a single power supply ranging from 1.68V to 3.6V. Key peripherals include USB 2.0 Device and Embedded Host capabilities, a segment LCD controller, an AES 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 a hardware Advanced Encryption Standard (AES) module for secure data processing.
- Features a dedicated Liquid Crystal Display (LCD) controller supporting passive displays.
- Supports direct peripheral-to-peripheral communication via the Peripheral Event System.
Applications
- Battery-powered portable devices requiring low standby current
- Secure IoT endpoints utilizing hardware encryption
- Applications driving monochrome passive LCD panels
- Systems requiring USB host or device connectivity
Procurement Notes
Verify the specific suffix 'UUR' against official Microchip documentation to confirm package type and tape-and-reel configuration. Ensure the ordering part number matches the required pin count and temperature range specifications before procurement.
Selection Notes
Select this component when a balance of moderate Flash capacity and robust security features is needed. The inclusion of both USB host/device modes and an LCD controller makes it suitable for complex user interfaces without external controllers.
Part Context
This part belongs to the SAM4L series, designed for low-power applications. The 'LC' designation indicates the inclusion of the LCD controller and AES module, distinguishing it from the LS series which lacks these specific features.
Replacement Considerations
Consult official substitution lists for equivalent packages or memory variants within the SAM4L family. Verify pin compatibility if replacing with other SAM4L models.
FAQ
Does the ATSAM4LC4BA support USB host functionality?
Yes, the ATSAM4LC series includes a full-speed USB 2.0 interface that supports both device and embedded host modes.
What is the maximum operating frequency of the Cortex-M4 core in this device?
The ARM Cortex-M4 processor runs at frequencies up to 48MHz.
