TMS320DM6433ZDU4

Digital Signal Processor Dsp Overview

The TMS320DM6433ZDU4 is a fixed-point digital media processor from the DaVinci family, featuring a C64x+ DSP core operating at 400 MHz. It delivers up to 3200 MIPS performance with an instruction cycle time of 2.5 ns. The device integrates a Video Processing Subsystem (VPSS) with hardware resizing and output capabilities, including four 54-MHz DACs for analog video. Key peripherals include a 10/100 Ethernet MAC, VLYNQ interface, PCI master/slave, and multiple serial ports. It utilizes a 376-pin Plastic BGA package (ZDU suffix) with 1.0-mm ball pitch, supporting 1.2-V core voltage and 1.8-V/3.3-V I/O levels.

Digital Signal Processor Dsp Feature Summary

• C64x+ DSP Core: 400 MHz clock rate, 8 independent functional units, VelociTI.2 extensions.

Digital Signal Processor Dsp Applications

• Digital Media Processors
• Networked Media Decode

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade (-4 suffix indicates 400 MHz) and package type (ZDU indicates 376-pin Plastic BGA) against project requirements. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure development tools such as C compilers and debuggers are compatible with the C64x+ architecture for software implementation.

Digital Signal Processor Dsp Selection Notes

Select this model when a 400 MHz processing speed is sufficient for the application. The ZDU package requires PCB layout support for a 376-pin BGA with 1.0-mm pitch. Consider the 1.2-V core voltage requirement for power supply design. Verify that the integrated VPSS meets video encoding/decoding needs without external processors.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320DM643x series of Digital Media Processors. It shares the same C64x+ core architecture and peripheral set as other variants in the DM643x family, differing primarily in maximum clock frequency and package options. The ZDU4 designation specifically identifies the 400 MHz speed bin within the 376-pin Plastic BGA form factor.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same package and speed grade may include other -4 speed bins in the ZDU package if available. Higher speed variants like ZDU5 or ZDU6 require verification of thermal and power constraints. Cross-family migration to newer DaVinci processors requires architectural review.
