TMS320DM6433ZWT5

Digital Signal Processor Dsp Overview

The TMS320DM6433ZWT5 is a fixed-point digital media processor based on the C64x+ DSP core, operating at a 500 MHz clock rate. It delivers 4000 MIPS performance with an instruction cycle time of 2 ns. The device features 32 KB L1 program cache, 80 KB L1 data cache, and 128 KB L2 unified RAM. It integrates a Video Processing Subsystem (VPSS) with hardware resizing, OSD, and video encoding capabilities. Power supplies include 1.2 V for the core and 1.8 V/3.3 V for I/O. The component is housed in a 361-pin PBGA package.

Digital Signal Processor Dsp Procurement Notes

Verify the -5 suffix indicates a 500 MHz speed grade against official Texas Instruments documentation. Confirm the ZWT suffix corresponds to the 361-pin Pb-Free PBGA package with 0.8 mm ball pitch. Check current production status as this series may be discontinued or subject to design changes.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring 500 MHz C64x+ performance with integrated video output. Ensure power supply designs accommodate 1.2 V core and 1.8 V/3.3 V I/O rails. Verify that the 361-pin BGA footprint matches the PCB layout constraints.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320DM643x DaVinci family of digital media processors. It shares the C64x+ architecture with variants like the DM6433ZWT4 (400 MHz), DM6433ZWT6 (600 MHz), and DM6433ZWTQ6 (660 MHz). The ZWT suffix denotes the specific 361-pin BGA package type used across these speed grades.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same package and pinout include TMS320DM6433ZWT4 (400 MHz) and TMS320DM6433ZWT6 (600 MHz). Verify software compatibility and timing requirements when swapping between different speed grades.
