Procurement Notes

Verify the specific revision level and manufacturing date code upon order confirmation. Ensure compatibility with host carrier board electrical specifications, particularly regarding the 1.23 V, 2.5 V, and 3.3 V power domains. Confirm that the required thermal management solutions align with the module's operational temperature range of 0°C to +70°C. Cross-reference pinout diagrams with the official Critical Link documentation before integration.

Selection Notes

Select this module when both high-performance DSP capabilities and reconfigurable logic are required in a compact SO-DIMM package. The combination of the TMS320C6711 and XC3S400 allows for complex algorithm execution alongside custom hardware acceleration. Consider the 8 MB SDRAM and 2 MB Flash limits for application memory requirements. Evaluate the need for McBSP interfaces versus other available communication protocols on the module.

Part Context

This part belongs to the MityDSP-XMF series by Critical Link, designed for embedded applications. It utilizes the TI TMS320C6711 DSP and Xilinx Spartan-3 FPGA. The module is intended for developers needing a pre-integrated solution to reduce design complexity. It serves as a building block for larger embedded systems requiring real-time processing and logic customization.

Replacement Considerations

Direct substitutes include the 6711-AA-1X1-RC variant, which shares the same core processor and FPGA but may differ in revision or specific component sourcing. Verify functional equivalence and mechanical compatibility before substitution. No other direct replacements are publicly confirmed for this exact configuration.
