Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade (375 MHz or 456 MHz) required for the application, as performance varies by voltage configuration. Confirm that the ZCE package dimensions (13 mm x 13 mm) fit the target PCB layout. Ensure compatibility with the 1.8-V or 3.3-V LVCMOS I/O standards specified in the datasheet.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring high-performance DSP processing with integrated connectivity. The 375 MHz version operates at 1.2 V core voltage, while the 456 MHz version requires 1.3 V. Consider the available pin count in the 361-ball package against the peripheral requirements, noting that some pins are multiplexed between different interfaces.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C674x family, which is code-compatible with the C6000 DSP platform. It combines the performance of the C64x+ core with the floating-point capabilities of the C67x+ core. The ZCE suffix indicates a 361-ball plastic ball grid array package with a 0.65-mm ball pitch.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same family include other TMS320C674x variants with different package sizes or speed grades, such as the TMS320C6746ZWT. Verify electrical characteristics and pinout compatibility before substitution.
