TMS320VC5503ZAY

Digital Signal Processor Dsp Overview

The TMS320VC5503ZAY is a fixed-point digital signal processor from the C55x family, manufactured by Texas Instruments. It features a 16-bit architecture with a maximum clock frequency of 200 MHz when operating at a core voltage (CVDD) of 1.6 V. The device integrates on-chip dual-access RAM (DARAM) and read-only memory (ROM). Key peripherals include three Multichannel Buffered Serial Ports (McBSP), a Direct Memory Access (DMA) controller, an I²C interface, and an Enhanced Host-Port Interface (EHPI). It supports boundary scan testing via JTAG and operates within a specified temperature range.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix ZAY against the manufacturer's official nomenclature guide to confirm package type and temperature grade. Ensure compatibility with existing board designs regarding pin assignments for the GHH or PGE packages as applicable. Confirm RoHS compliance status through current datasheet revisions before procurement.

Digital Signal Processor Dsp Selection Notes

Select this component based on required clock speed and voltage constraints. A 200 MHz performance requires a 1.6 V core supply, while lower speeds allow reduced voltage operation for power savings. Verify that the integrated memory sizes meet application requirements and that peripheral interfaces like McBSP and EHPI align with system connectivity needs.

Digital Signal Processor Dsp Part Context

This device belongs to the TMS320VC5503 series within the broader C5000 DSP family. It shares architectural similarities with other C55x processors but offers specific memory configurations and peripheral sets tailored for cost-sensitive, low-power applications. The ZAY suffix typically denotes a specific package and temperature rating variant within this product line.

Digital Signal Processor Dsp Replacement Considerations

Consult the official cross-reference list for direct replacements. Potential alternatives within the same family may include other C55x variants with compatible pinouts and similar memory/peripheral configurations. Verify electrical characteristics and software compatibility before substitution.
