Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., -720, -850, -1000, -1200) required for the target clock frequency. Confirm that the BGA package type matches the design footprint. Ensure environmental specifications align with commercial or extended temperature requirements as defined in the datasheet electrical characteristics.

Digital Signal Processor Dsp Selection Notes

Select the appropriate speed bin based on the required system clock frequency and instruction cycle time. Consider the available peripheral pin multiplexing options, as some interfaces like PCI and HPI share pins. Verify power supply voltage compatibility for the 1.2 V core and 1.2 V to 3.3 V I/Os.

Digital Signal Processor Dsp Part Context

This component belongs to the Texas Instruments TMS320C6000 platform, specifically the third-generation C64x+ family. It utilizes a 0.09-μm CMOS process technology and offers upward code compatibility with previous C6000 devices while providing enhanced multiply throughput and new instruction set features.

Digital Signal Processor Dsp Replacement Considerations

Check for other speed grades within the TMS320C6455 series (CTZ, GTZ, ZTZ packages) if different clock frequencies are needed. Verify pinout compatibility when considering upgrades to other C64x+ variants.
