TMS320DM642AZNZA6

Digital Signal Processor Dsp Overview

The TMS320DM642AZNZA6 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 parallel processing. It includes 16 KB L1P cache, 16 KB L1D cache, and 256 KB configurable L2 memory. Key peripherals include three configurable video ports, a 10/100 Mb/s Ethernet MAC, McASP, I2C, McBSP, and a 64-bit external memory interface.

Digital Signal Processor Dsp Feature Summary

• C64x+ DSP Core: 8 independent functional units (6 ALUs, 2 multipliers) supporting quad 8-bit/dual 16-bit operations via VelociTI.2 extensions.
• Memory Architecture: 16-KByte L1P direct-mapped cache, 16-KByte L1D 2-way set-associative cache, and 256-KByte flexible L2 RAM/cache.
• Video Interface: Three configurable video ports (VP0–VP2) providing glueless interfaces to common video codecs.
• Connectivity: Integrated 10/100 Mb/s Ethernet MAC (EMAC), Multichannel Audio Serial Port (McASP), and PCI master/slave interface.

Digital Signal Processor Dsp Applications

• Digital multimedia applications requiring high-performance video compression/decompression
• Video surveillance and security systems
• Medical imaging and industrial machine vision
• Telecommunications equipment

Digital Signal Processor Dsp Procurement Notes

Verify the suffix 'A' indicates a specific speed grade or revision within the DM642 family. Confirm package dimensions match the 548-pin BGA specifications (23x23 mm or 27x27 mm depending on pitch). Ensure development tools are compatible with the C6000 platform.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring up to 5760 MIPS performance. Verify power supply requirements: 1.2 V core voltage for -500 variants or 1.4 V for A-500/-600/-720 variants. Check peripheral availability as some pins are multiplexed between EMAC, PCI, HPI, and Video Ports.

Digital Signal Processor Dsp Part Context

The TMS320DM642 belongs to the Texas Instruments C6000 DSP platform. It is code-compatible with other C64x devices but adds specialized hardware for video and imaging. The 'Z' in the part number typically denotes a specific package type and pin pitch configuration within the BGA family.

Digital Signal Processor Dsp Replacement Considerations

TMS320DM643 series offers higher performance and integrated ARM9 cores. TMS320DM644 provides similar DSP capabilities with different peripheral sets. Direct pin-to-pin replacements may require schematic review due to peripheral multiplexing differences.
