TMS320DM6433ZWTQ5

Digital Signal Processor Dsp Overview

The TMS320DM6433ZWTQ5 is a fixed-point digital media processor based on the C64x+ DSP core, operating at a maximum clock rate of 500 MHz. It delivers 4000 MIPS performance with an instruction cycle time of 2 ns. The device features a two-level cache architecture comprising 32 KB L1 program memory/cache, 80 KB L1 data memory/cache, and 128 KB L2 unified mapped RAM/cache. It includes 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 Feature Summary

• Video Processing Subsystem (VPSS): Hardware resizer supporting 1/4x to 4x scaling, On-Screen Display (OSD), and Video Encoder (VENC) with four 54-MHz DACs.
• Memory Architecture: 32 KB L1P, 80 KB L1D, and 128 KB L2 memory; supports DDR2 SDRAM via 32-bit controller and asynchronous EMIF.
• Peripherals: Includes 10/100 Mb/s Ethernet MAC (EMAC), Multichannel Audio Serial Port (McASP0), McBSP, I2C, UART, PCI, and up to 111 GPIO pins.

Digital Signal Processor Dsp Applications

• Digital media processing
• Networked media decode
• Video surveillance systems

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix Q5 indicates the 500 MHz speed grade against the official datasheet. Confirm the ZWT package designation corresponds to the 361-pin Pb-Free PBGA with 0.8-mm ball pitch. Ensure compatibility with required voltage levels (1.2 V core, 1.8 V/3.3 V I/O) during design validation.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring 500 MHz C64x+ performance with integrated video processing. Compare with -Q6 (660 MHz) or -L (low power) variants if higher throughput or reduced power consumption is needed. Verify that the 361-pin BGA footprint matches the PCB layout constraints.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320DM643x Digital Media MegaModule family within the DaVinci series. It shares the C64x+ core and VPSS architecture with other variants like the DM6437 and DM6435, differing primarily in clock speed and package options. The ZWT suffix specifically denotes the plastic ball grid array package type.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same family include TMS320DM6433ZWTQ6 (660 MHz) and TMS320DM6433ZWTQ4 (400 MHz). For lower power requirements, consider the TMS320DM6433ZWT-L variant. Package-compatible alternatives may exist in the DM6437 series if pinouts are identical.
