TMS320DM642AGDKA6

Digital Signal Processor Dsp Overview

The TMS320DM642AGDKA6 is a video and 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 VelociTI.2 extensions for quad 8-bit and dual 16-bit parallel processing. Key peripherals include three configurable video ports, a 10/100 Mb/s Ethernet MAC, an EMAC, McASP0, I2C, McBSPs, timers, GPIO, and a PCI interface. It utilizes a 0.13-µm CMOS process with 3.3-V I/O and 1.4-V internal core voltage. The component is housed in a 548-pin BGA package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., A600) against the required operating frequency. Confirm the package type matches the design footprint, as the DM642 family includes both 0.8-mm and 1.0-mm pitch variants. Ensure compatibility with existing development tools and compiler versions for the C6000 platform.

Digital Signal Processor Dsp Selection Notes

Select the appropriate speed grade based on the target instruction throughput requirements. The 'A' prefix indicates a 1.4-V core voltage, distinct from the 1.2-V '-500' variant. Consider peripheral multiplexing constraints; certain pins are shared between Video Ports, McBSPs, and other interfaces, requiring careful pin configuration during hardware design.

Digital Signal Processor Dsp Part Context

This device belongs to the Texas Instruments TMS320C6000 DSP platform, specifically the DM64x series optimized for digital media. It is code-compatible with other C64x devices like the TMS320C6416 and TMS320C6421. The DM642 integrates application-specific hardware logic for video and imaging, distinguishing it from general-purpose C64x processors.
