TMS320VC5421GGU200

Digital Signal Processor Dsp Overview

The TMS320VC5421GGU200 is a fixed-point digital signal processor based on the C54x core, manufactured by Texas Instruments. It features a dual-subsystem architecture with two independent DSP cores, each equipped with dedicated program and data spaces. The device operates at a maximum clock frequency of 200 MHz and utilizes a 16-bit data bus width. It includes on-chip memory comprising dual-access RAM (DARAM), single-access RAM (SARAM), and boot ROM. The component is housed in a 144-ball MicroStar BGA package and supports a host-port interface (HPI16) for external communication.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix 'GGU200' against the official SPRS098C datasheet to confirm the package type and speed grade. Confirm current production status and availability through authorized distributors, as older silicon revisions may have limited supply chains.

Digital Signal Processor Dsp Selection Notes

Select this model when a dual-core C54x DSP is required for high-throughput signal processing. Ensure the design accommodates the 144-ball BGA footprint and provides necessary power delivery for the 1.6 V core voltage. Verify that the 200 MHz performance meets the system timing requirements.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320VC5421 series within the Texas Instruments C54x family. It serves as an evolution of earlier single-core devices like the TMS320VC5420, providing enhanced computational density through its dual-subsystem design.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements include other variants within the TMS320VC5421 family with different speed grades or packages, such as the TMS320VC5421PGE. Cross-model migration from the TMS320VC5420 is supported via pin-compatible options.
