TMS320DM6433ZWTL

Digital Signal Processor Dsp Overview

The TMS320DM6433ZWTL is a digital media processor from the DaVinci family, featuring a C64x+ DSP core operating at 600 MHz. It integrates a Video Processing Subsystem (VPSS) with hardware resizing and VelociTI.2 extensions for video acceleration. The device includes 32 KB L1 program cache, 80 KB L1 data cache, and 128 KB unified L2 RAM. Power supplies are 1.2 V for the core and 1.8 V/3.3 V for I/O. It is housed in a 361-pin PBGA package (ZWT suffix) with a 0.8-mm ball pitch.

Digital Signal Processor Dsp Procurement Notes

Verify the -L suffix indicates a low-power variant with specific voltage requirements. Confirm the ZWT package designation matches the required 361-pin BGA footprint. Check current production status as this model may be subject to availability constraints or end-of-life notices.

Digital Signal Processor Dsp Selection Notes

Select this part for applications requiring fixed-point DSP processing combined with dedicated video encoding/decoding hardware. Ensure the design supports the 1.2 V core voltage and 1.8 V/3.3 V I/O levels. Verify that the 600 MHz speed grade meets the real-time processing requirements of the target video resolution.

Digital Signal Processor Dsp Part Context

This component belongs to the Texas Instruments TMS320DM643x series within the DaVinci architecture. It shares the C64x+ core and VPSS block with variants like the DM6435 and DM6437, differing primarily in clock speed and memory configuration. The ZWT suffix specifically denotes the 361-pin plastic BGA package.

Digital Signal Processor Dsp Replacement Considerations

Direct functional substitutes include other members of the TMS320DM643x family, such as the TMS320DM6435 or TMS320DM6437, provided pin compatibility and speed grades align with system requirements.
