TMS320C6747DZKB3

Digital Signal Processor Dsp Overview

The TMS320C6747DZKB3 is a fixed- and floating-point digital signal processor based on the C674x VLIW architecture, operating at frequencies up to 456 MHz. It features a two-level cache memory system comprising 32 KB L1P, 32 KB L1D, and 256 KB L2 unified RAM/cache. The device includes 448 KB of total on-chip RAM, with an additional 128 KB shared memory accessible by other hosts. Key peripherals include a 10/100 Mbps Ethernet MAC, USB 2.0 OTG and USB 1.1 OHCI controllers, three McASPs, and a Programmable Real-Time Unit Subsystem (PRUSS). It is housed in a 256-ball PBGA package.

Digital Signal Processor Dsp Feature Summary

• C674x DSP core delivering up to 3648 MIPS and 2736 MFLOPS performance
• Integrated USB 2.0 High-Speed OTG controller with PHY and USB 1.1 OHCI host controller
• 128 KB dedicated shared RAM for non-DSP host access without affecting DSP performance
• Programmable Real-Time Unit Subsystem (PRUSS) with two independent PRU cores

Digital Signal Processor Dsp Applications

• A/V Receivers
• Automotive Amplifiers
• Soundbars
• Home Theatre Systems
• Professional Audio

Digital Signal Processor Dsp Procurement Notes

Verify the specific silicon revision and temperature grade required for the application. Confirm that the 256-ball PBGA package dimensions and thermal characteristics meet the PCB layout constraints. Ensure compatibility with existing software drivers for the EMAC, USB, and PRUSS subsystems before finalizing procurement.

Digital Signal Processor Dsp Selection Notes

Select this model over the TMS320C6745 if high-speed USB 2.0 OTG functionality, a second USB 1.1 host port, LCD controller support, or the 128 KB shared RAM are required. Verify that the 256-pin BGA package is suitable for the manufacturing process. Check if the 456 MHz operation at 1.3V core voltage fits within the system power budget compared to the 375 MHz option.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C674x family of low-power DSPs from Texas Instruments. It is code-compatible with the C6000 platform, supporting instructions from both C64x+ and C67x+ families. The DZKB suffix indicates the 456 MHz speed grade, ZKB package type (256-ball PBGA), and commercial temperature range.

Digital Signal Processor Dsp Replacement Considerations

TMS320C6745PTP: Equivalent performance but lacks USB 2.0 HS, LCD controller, and shared RAM; uses 176-pin QFP package.
