Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'ZQW10' against official Texas Instruments documentation to confirm the exact speed grade and package variant. Check for End-of-Life (EOL) status or Last Time Buy notices, as older C55x variants may have limited availability through primary channels.

Digital Signal Processor Dsp Selection Notes

Select this component when a balance of moderate processing power (100 MHz) and low power consumption is required. Ensure the design accommodates the 118-ball BGA footprint and utilizes the appropriate voltage regulators for the 1.05 V core and 1.8-3.3 V I/O domains.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C5545 family, which is designed for high-performance, low-power applications. It shares architectural similarities with other C55x processors but offers specific memory sizes and interface combinations tailored for cost-sensitive embedded solutions.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements within the same package are limited. Consider the TMS320C5545AZQW12 (120 MHz) or TMS320C5545AZQW14 (140 MHz) if higher performance is needed and timing constraints allow. Verify software compatibility across different speed grades.
