• Biometric Identification
• Low-End Machine Vision

Digital Signal Processor Dsp Procurement Notes

Verify the ordering suffix 'BZWT4' corresponds to the specific package dimensions (16x16 mm NFBGA) and temperature rating required for the design. Confirm that the 1.3 V core voltage requirement aligns with the target power supply architecture. Ensure compliance with RoHS3 specifications as indicated in manufacturer documentation.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high-performance floating-point DSP capabilities combined with direct storage connectivity via SATA. The 456 MHz speed grade necessitates a 1.3 V core supply. Consider the 361-ball NFBGA footprint for PCB layout constraints. Verify peripheral availability, as some functions share pin multiplexing resources.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C674x family, which is code-compatible with the broader C6000 DSP platform. It combines the performance of the C64x+ core with the floating-point features of the C67x+ core. The BZWT4 designation specifically identifies the industrial or extended temperature variant within the 16x16 mm package option.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6748EZWT4 is a confirmed alternative offering 375 MHz operation at a lower 1.2 V core voltage. Both parts share the same 361-NFBGA (16x16) package and pinout, ensuring mechanical compatibility while differing in clock speed and power requirements.
