TMS320DM642AZDKA5

Digital Signal Processor Dsp Overview

The TMS320DM642AZDKA5 is a video/imaging fixed-point digital signal processor based on the C64x+ DSP core. It operates at clock rates of 500, 600, or 720 MHz, delivering up to 5760 MIPS. The device features an advanced VLIW architecture with eight functional units and VelociTI.2 extensions for multimedia acceleration. On-chip memory includes 16 KB L1P cache, 16 KB L1D cache, and 256 KB unified L2 RAM/cache. Key peripherals include three configurable video ports, a 10/100 Mb/s Ethernet MAC, McASP, McBSP, PCI, and EMIF. It utilizes a 548-pin BGA package with 0.8-mm ball pitch.

Digital Signal Processor Dsp Procurement Notes

Verify component authenticity through authorized channels as this part number may be subject to obsolescence. Confirm specific speed grade suffixes (-500, -600, -720) match design requirements. Ensure RoHS compliance status aligns with current manufacturing data sheets. Check for availability of development tools compatible with the C6000 platform.

Digital Signal Processor Dsp Selection Notes

Select the appropriate speed grade suffix based on required instruction cycle time (2 ns, 1.67 ns, or 1.39 ns). Verify power supply requirements: 1.2 V core voltage for -500 grade, 1.4 V for A-500/-600/-720 grades. Ensure PCB layout supports the 548-pin BGA package with 0.8-mm ball pitch. Confirm peripheral pin multiplexing constraints for video and audio interfaces.

Digital Signal Processor Dsp Part Context

This device belongs to the TMS320C6000 DSP platform, specifically the DM64x series optimized for video and imaging applications. It is code-compatible with other C64x devices but offers enhanced VelociTI.2 extensions. The ZDK suffix indicates a specific package variant within the 548-pin BGA family designed for high-density mounting.
