TMS320DM643AGDK6

Digital Signal Processor Dsp Overview

The TMS320DM643AGDK6 is a video/imaging fixed-point digital signal processor based on the C64x DSP core with VelociTI.2 extensions. It operates at clock rates of 500 MHz or 600 MHz, delivering up to 4800 MIPS. The device features eight independent functional units and 64 general-purpose registers. On-chip memory includes a 16-KByte L1P cache, a 16-KByte L1D cache, and a 256-KByte unified L2 RAM/cache. Key peripherals include two configurable video ports, a 10/100 Mb/s Ethernet MAC, McASP0, McBSP, I2C, and an EMIFA. It utilizes a 548-pin BGA package with a 0.8-mm ball pitch.

Digital Signal Processor Dsp Feature Summary

• C64x DSP Core: 500-MHz or 600-MHz clock rate with VelociTI.2 extensions for quad 8-bit and dual 16-bit operations.
• Memory Architecture: 16-KByte direct-mapped L1P cache, 16-KByte 2-way set-associative L1D cache, and 256-KByte flexible L2 RAM/cache.
• Video Interface: Two configurable video ports (VP1, VP2) supporting multiple resolutions and standards like CCIR601 and ITU-BT.656.
• Connectivity: Integrated 10/100 Mb/s Ethernet MAC (EMAC), MDIO, VCXO Interpolated Control Port (VIC), and Multichannel Audio Serial Port (McASP0).

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'GDK6' against official documentation, as standard listings typically reference 'GDK'. Confirm availability status, as this component may be discontinued. Ensure compliance with RoHS requirements and check for lead-free specifications in the final datasheet revision.

Digital Signal Processor Dsp Selection Notes

Select the -500 variant for 1.2-V internal core voltage or the -600 variant for 1.4-V internal core voltage. The GDK suffix indicates a 548-pin BGA package with a 0.8-mm ball pitch. Verify pin multiplexing configurations for EMAC/HPI and VP1/McASP0 if both are required simultaneously.

Digital Signal Processor Dsp Part Context

The TMS320DM643 belongs to the C6000 DSP platform and is code-compatible with other C64x devices. It shares architectural similarities with the DM642 but offers enhanced peripheral integration for video and imaging tasks. The device supports both little-endian and big-endian modes.

Digital Signal Processor Dsp Replacement Considerations

Consult the TMS320DM642 Technical Overview (SPRU615) for compatibility details with other C64x devices. No direct public substitute part numbers are confirmed for this specific model.
