TMS320DM643AZNZA5

Digital Signal Processor Dsp Overview

The TMS320DM643AZNZA5 is a video and 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 for high parallelism. 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 with a 1.0-mm ball pitch.

Digital Signal Processor Dsp Feature Summary

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

Digital Signal Processor Dsp Applications

• Video conferencing systems
• Network video surveillance
• Medical imaging processing

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (-A5 indicates 500 MHz) against design requirements. Confirm the 548-pin BGA package dimensions match the PCB footprint. Check RoHS compliance status as per the latest datasheet revision. Ensure availability aligns with production timelines.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high-performance fixed-point DSP processing with integrated networking and video interfaces. Compare the -500 (1.2 V core) and -600 (1.4 V core) variants based on power constraints and performance needs. Ensure sufficient external memory bandwidth supports the EMIFA interface requirements.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320DM64x series within the C6000 DSP platform. It shares architectural similarities with the DM642 but adds integrated Ethernet capabilities. The ZNZ suffix denotes the 548-pin BGA package with 1.0-mm ball pitch and big-endian support options.

Digital Signal Processor Dsp Replacement Considerations

The TMS320DM642 is a code-compatible alternative lacking the integrated Ethernet MAC. Other C64x devices may require significant peripheral redesign due to pinout and memory interface differences.
