TMS320DM643AZNZ6

Digital Signal Processor Dsp Overview

The TMS320DM643AZNZ6 is a video/imaging fixed-point digital signal processor based on the C64x DSP core. It operates at clock rates of 500 MHz or 600 MHz, delivering up to 4800 MIPS. The device features VelociTI.2 extensions with eight functional units and 64 general-purpose registers. On-chip memory includes 16 KB L1P cache, 16 KB L1D cache, and 256 KB L2 unified RAM/cache. Core voltage is 1.2 V for the -500 variant and 1.4 V for the -600 variant, with 3.3 V I/O. It utilizes a 548-pin BGA package (27 x 27 mm) with a 1.0-mm ball pitch.

Digital Signal Processor Dsp Feature Summary

• C64x DSP core with VelociTI.2 extensions providing up to 4800 MMACS performance
• Integrated 10/100 Mb/s Ethernet MAC (EMAC) with MDIO module
• Two configurable video ports (VP1, VP2) supporting multiple video standards
• Multichannel Audio Serial Port (McASP0) with S/PDIF transmitter support

Digital Signal Processor Dsp Applications

• Digital media processing systems
• Video codec implementations
• Networked video transmission endpoints
• Imaging applications requiring high-performance fixed-point processing

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (-500 or -600) required for the target clock frequency, as this determines the internal core voltage (1.2 V vs 1.4 V). Confirm that the GNZ/ZNZ package designation matches the required pinout configuration for big-endian support if applicable. Ensure compatibility with existing board designs regarding the 548-pin BGA footprint and thermal requirements.

Digital Signal Processor Dsp Selection Notes

Select the -500 variant for 500 MHz operation requiring 1.2 V core voltage, or the -600 variant for 600 MHz operation requiring 1.4 V core voltage. The ZNZ suffix indicates a 548-pin BGA package with 1.0-mm ball pitch and supports big-endian mode. Verify peripheral multiplexing constraints, particularly between VP1 and McASP0 data pins, when designing the hardware interface.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C6000 DSP platform, specifically the DM643 series designed for video and imaging applications. It is code-compatible with other C64x devices. The device integrates specialized peripherals like EMAC and Video Ports alongside the standard C64x computational engine, distinguishing it from generic C64x processors by its multimedia-focused peripheral set.
