TMS320DM643AGNZ6

Digital Signal Processor Dsp Overview

The TMS320DM643AGNZ6 is a video/imaging fixed-point digital signal processor from the DaVinci family, manufactured by Texas Instruments. It features a C64x DSP core operating at up to 600 MHz with VelociTI.2 extensions, delivering 4800 MIPS. The device utilizes a 0.13-µm CMOS process and includes 16 KB L1P cache, 16 KB L1D cache, and 256 KB L2 unified memory. Key peripherals include two configurable video ports (VP1/VP2), a 10/100 Mb/s Ethernet MAC, McASP0, and an EMIF. The GNZ suffix indicates support for big-endian mode and a 27 x 27 mm 548-pin BGA package with 1.0-mm ball pitch.

Digital Signal Processor Dsp Feature Summary

• C64x DSP Core: 600 MHz clock rate, 4800 MIPS performance, and VelociTI.2 extensions for video acceleration.
• Memory Architecture: 16 KB L1P direct-mapped cache, 16 KB L1D 2-way set-associative cache, and 256 KB L2 unified RAM/cache.
• Video & Audio Interfaces: Two configurable video ports supporting multiple standards; McASP0 with integrated S/PDIF transmitter.
• Connectivity: Integrated 10/100 Mb/s Ethernet MAC (EMAC) with MDIO module and Host-Port Interface (HPI).
• Package & Power: 548-pin BGA (27 x 27 mm, 1.0-mm pitch); 1.4 V internal core voltage for -600 speed grade.

Digital Signal Processor Dsp Applications

• Digital media processing and video surveillance systems.
• Network video recorders (NVRs) and IP cameras.
• Medical imaging equipment requiring high-performance fixed-point processing.
• Industrial automation and security applications.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade (-500 or -600) required for the application, as this determines the internal core voltage (1.2 V vs. 1.4 V). Confirm that the GNZ suffix matches the necessary endianness configuration (Big Endian support) and physical package dimensions (27 x 27 mm BGA). Ensure compatibility with existing board layouts regarding the 1.0-mm ball pitch.

Digital Signal Processor Dsp Selection Notes

Select the TMS320DM643AGNZ6 when Big Endian operation is required alongside high-speed video processing capabilities. Compare against the ZNZ suffix variant if Little Endian is preferred but the same package size is needed. Evaluate the -600 speed grade for maximum throughput (600 MHz) versus the -500 grade (500 MHz) based on thermal and power constraints.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320DM64x series within the DaVinci platform. It is code-compatible with other C6000 DSP devices like the TMS320DM642. The GNZ suffix specifically denotes the 27 x 27 mm 548-pin BGA package with 1.0-mm pitch and Big Endian capability, distinguishing it from the GDK/ZDK variants which use a 23 x 23 mm package.
