Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix ZWTQ5 against official Texas Instruments documentation to confirm pinout compatibility and electrical characteristics. Ensure the component meets RoHS compliance requirements if mandated by the design specification. Cross-reference the ECCN code 3A001.A.3 for export control regulations relevant to the procurement region.

Digital Signal Processor Dsp Selection Notes

Select this model when a 600 MHz C64x+ performance level is required within a compact 361-ball BGA footprint. Compare against the TMS320C6421ZDUL variant if a 376-pin package is preferred for board layout flexibility. Consider the TMS320C6421ZWT6 if a different temperature grade or packaging configuration is necessary for the target environment.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C642x family, which also includes variants such as the TMS320C6421ZDU4 and TMS320C6421ZWT6. These devices share the same core architecture but differ in package types (BGA-376 vs NFBGA-361) and specific operational parameters. The ZWTQ5 designation identifies the specific package and thermal rating within this product line.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes include other TMS320C6421 variants like the TMS320C6421ZWT6 or TMS320C6421ZDU4, provided the package difference (361-pin vs 376-pin) is accommodated in the PCB design. Verify that the replacement part maintains the required 600 MHz clock speed and memory configuration.
