TMS320DM643AZDK6

Digital Signal Processor Dsp Overview

The TMS320DM643AZDK6 is a video/imaging fixed-point digital signal processor from the DaVinci family, manufactured by Texas Instruments. It features a C64x DSP core with VelociTI.2 extensions, operating at clock rates of 500 MHz or 600 MHz. The device utilizes a 0.13-µm CMOS process and includes 16 KB L1P cache, 16 KB L1D cache, and 256 KB L2 unified RAM/cache. Key peripherals include two configurable video ports (VP1, VP2), a 10/100 Mb/s Ethernet MAC, McASP0, McBSP, I2C, and an EMIFA. It is housed in a 548-pin BGA package with a 0.8-mm ball pitch.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (-500 or -600) required for the design, as the base model number does not specify the clock frequency. Confirm that the ZDK6 suffix corresponds to the 548-pin BGA package with 0.8-mm ball pitch and industrial temperature range if applicable, based on the official datasheet definitions for the DM643 series.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring high-performance fixed-point DSP processing with integrated video and networking capabilities. Ensure the system design supports the 1.2 V or 1.4 V internal core voltage and 3.3 V I/O requirements. Consider the multiplexed pin configurations between VP1, McASP0, and HPI when designing the PCB layout.

Digital Signal Processor Dsp Part Context

This device belongs to the TMS320DM64x series within the C6000 DSP platform. It is code-compatible with other C64x devices but offers enhanced peripheral integration specifically for video and imaging applications, distinguishing it from standard C64x processors.

Digital Signal Processor Dsp Replacement Considerations

Check for direct replacements within the TMS320DM64x family, such as the TMS320DM6437 or TMS320DM6446, ensuring compatibility with the 548-pin BGA package and peripheral set. Verify software compatibility with the C64x instruction set.
