Overview
The ATSAM4SD16CB-AN is a 32-bit microcontroller from the Microchip SAM4S series, featuring an ARM Cortex-M4 core operating at up to 120 MHz. It integrates 1 MB of embedded Flash memory and 160 KB of SRAM. The device includes a Static Memory Controller (SMC) supporting external memory expansion via EBI/EMI. Connectivity options include USB 2.0 Device, I2C, SPI, USART, and SD/MMC interfaces. It operates within a voltage range of 1.62V to 3.6V and supports an industrial temperature range of -40°C to 105°C.
Feature Summary
- Integrates an ARM Cortex-M4 processor with DSP instructions and a Memory Protection Unit for secure execution.
- Includes a Static Memory Controller enabling direct interfacing with external SRAM, PSRAM, NOR, or NAND Flash memories.
- Features a comprehensive set of peripherals including USB 2.0, multiple serial communication interfaces, and high-resolution analog-to-digital converters.
Applications
- Industrial control systems requiring external memory expansion
- USB-enabled data logging devices
- Smart metering applications
Procurement Notes
Verify the specific suffix 'AN' against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 100-TFBGA package. Check for any recent Product Change Notifications regarding assembly sites or material composition updates before finalizing procurement.
Selection Notes
Select this component when 1 MB of Flash and 160 KB of RAM are required alongside external memory capabilities. The inclusion of the Static Memory Controller distinguishes it from smaller SAM4S variants lacking EBI support. Consider the 100-pin TFBGA package constraints for thermal management and board space in dense designs.
Part Context
This part belongs to the SAM4S family, which provides pin-to-pin compatibility with SAM3N and SAM3S products in certain pin counts. It utilizes the same ARM Cortex-M4 core architecture found across the broader SAM4 series, allowing for software portability while offering specific memory and peripheral configurations tailored for cost-sensitive embedded applications.
Replacement Considerations
ATSAM4SD16CA-AU offers identical specifications but in a 100-LQFP package. ATSAM4SD16CB-CN is another BGA variant; verify if the 'CN' suffix denotes a different temperature grade or package dimension compared to 'AN'. Cross-reference errata documents for both parts to ensure functional equivalence.
