ATSAM3SD8CA-CUR

Microcontrollers Overview

The ATSAM3SD8CA-CUR is a 32-bit microcontroller from the Microchip SAM3S series, featuring an ARM Cortex-M3 core operating at up to 64 MHz. It integrates 512 KB of Flash memory and 64 KB of SRAM within a 100-pin TFBGA package (9x9 mm). The device supports a supply voltage range of 1.62 V to 3.6 V and includes integrated USB OTG capabilities alongside standard communication interfaces such as SPI, I2C, and USART.

Microcontrollers Feature Summary

• Integrates USB On-The-Go (OTG) controller for direct peripheral connectivity without host dependency.
• Includes dedicated DMA channels to offload data transfer tasks from the CPU, enhancing processing efficiency.
• Features multiple high-speed synchronous serial communication interfaces including SPI and SSC for audio applications.

Microcontrollers Applications

• USB-enabled consumer electronics devices
• Industrial control systems requiring robust serial communication
• Portable medical equipment with data logging needs

Microcontrollers Procurement Notes

Verify the specific suffix 'CUR' indicates the TFBGA-100 package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status through official Microchip documentation prior to integration. Ensure ESD handling protocols are followed due to the fine-pitch BGA packaging format.

Microcontrollers Selection Notes

Select this component when USB OTG functionality is required alongside moderate code storage capacity. Compare against the ATSAM3S8CA variant if USB support is unnecessary, or consider the ATSAM4S series for higher clock speeds and DSP instructions. Verify pin compatibility if replacing older SAM3S models in existing designs.

Microcontrollers Part Context

This part belongs to the SAM3S family, designed for cost-sensitive applications requiring efficient performance. It shares architectural similarities with other SAM3S variants but distinguishes itself through the inclusion of the USB OTG module, making it suitable for standalone peripheral roles.

Microcontrollers Replacement Considerations

ATSAM3SD8CA-AU offers identical specifications in an LQFP package. ATSAM3S8CA-CUR provides similar performance but lacks the USB OTG interface. Cross-referencing datasheets is essential to confirm peripheral availability and pinout differences.
