ATSAM3SD8CA-AUR

Overview

The ATSAM3SD8CA-AUR is a 32-bit microcontroller from the Microchip SAM3S series, featuring an ARM Cortex-M3 core operating at up to 64MHz. It integrates 512KB of Flash memory and 64KB of SRAM within a 100-LQFP package. The device supports a supply voltage range of 1.62V to 3.6V and includes a USB Full-Speed interface alongside multiple communication peripherals such as SPI, I2C, and USART.

Feature Summary

• Integrates a high-performance ARM Cortex-M3 processor with hardware multiply and divide instructions for efficient code execution.
• Includes a dedicated USB Full-Speed controller with built-in endpoint buffers to facilitate direct host connectivity.
• Features advanced analog capabilities with multiple ADC channels and DAC outputs for signal processing applications.

Applications

• USB-enabled peripheral devices requiring direct host communication
• Industrial control systems utilizing serial communication protocols
• Data acquisition modules with analog input/output requirements

Procurement Notes

Verify the specific suffix 'AUR' indicates tape and reel packaging when ordering. Confirm assembly site and environmental compliance details via the latest manufacturer datasheet or product change notices prior to final design implementation.

Selection Notes

Select this component for designs requiring integrated USB connectivity without external transceivers. Compare against the ATSAM3S8CA variant if USB functionality is unnecessary, as it offers similar processing power with potentially different peripheral availability.

Part Context

This part belongs to the SAM3S family, which targets cost-sensitive applications needing moderate performance. It serves as a bridge between low-end 8/16-bit controllers and higher-performance ARM Cortex-M4 solutions like the SAM4S series.

Replacement Considerations

ATSAM3S8CA-AUR: Similar core and memory but lacks the integrated USB controller found in the SD8 variant.
