TMS320VC5420ZGU200

Digital Signal Processor Dsp Overview

The TMS320VC5420ZGU200 is a dual-core fixed-point digital signal processor from the TMS320C54x family, manufactured by Texas Instruments. It integrates two independent C54x subsystems capable of up to 200-MIPS performance per core. The architecture features a 40-bit ALU with a barrel shifter and accumulators, alongside a 17x17-bit parallel multiplier for single-cycle MAC operations. Each core includes dedicated address generators, CSSU logic, and exponent encoders. The device utilizes a modified Harvard architecture with separate program and data buses, supporting 16-bit data widths. It operates on dual power supplies: 1.8 V for the core and 3.3 V for I/O, housed in a 144-pin BGA package.

Digital Signal Processor Dsp Feature Summary

• Dual-CPU Architecture: Two independent C54x subsystems with interprocessor communication via internal FIFOs.
• High-Performance Arithmetic: 40-bit ALU, 17x17-bit multiplier, and single-cycle MAC operations.
• On-Chip Memory: Total of 192K x 16 dual/single-access RAM distributed across both cores.
• Peripheral Integration: Includes six McBSPs, twelve DMA channels, and a 16-bit Host Port Interface (HPI16).

Digital Signal Processor Dsp Applications

• Multichannel audio processing and codec applications
• Modems and telecommunications equipment
• Industrial control systems requiring high-speed DSP
• Software-defined radio implementations

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'ZGU' against official documentation to confirm package type and temperature range. Confirm that the '200' designation aligns with the required clock frequency specifications. Ensure compatibility with existing board layouts for the 144-pin BGA footprint. Check for end-of-life status or alternative sourcing requirements as this component belongs to an older generation of processors.

Digital Signal Processor Dsp Selection Notes

Select this model when dual-core processing is required within the C54x ecosystem. Ensure the design supports the 1.8 V core and 3.3 V I/O voltage domains. Verify that the 144-pin BGA package fits the mechanical constraints of the target enclosure. Consider the pin multiplexing capabilities if external memory interfaces are needed alongside host port access.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320VC5420 series, which extends the standard single-core C54x architecture into a dual-subsystem configuration. It shares architectural similarities with other C54x devices but offers increased throughput through parallel processing. The ZGU suffix specifically denotes the 144-pin MicroStar BGA package variant available in commercial temperature ranges.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements include other TMS320VC5420 variants such as TMS320VC5420GGU200 or TMS320VC5420PGE200, depending on package preference. Single-core alternatives like the TMS320VC5416 may be considered if dual-core functionality is not strictly required.
