TMS320C6747BZKB4

Digital Signal Processor Dsp Overview

The TMS320C6747BZKB4 is a fixed- and floating-point digital signal processor based on the TMS320C674x DSP core. It operates at clock rates of 375 MHz (1.2V) or 456 MHz (1.3V). The device features a two-level cache architecture with 32 KB L1P, 32 KB L1D, and 256 KB L2 memory, plus an additional 128 KB shared RAM. It includes a PRU subsystem, USB 2.0 OTG, Ethernet MAC, and multiple serial interfaces. The component is housed in a 256-ball PBGA package measuring 17 mm x 17 mm.

Digital Signal Processor Dsp Feature Summary

• TMS320C674x VLIW DSP core supporting up to 3648 MIPS and 2736 MFLOPS
• Two external memory interfaces: EMIFA and EMIFB for SDRAM/NOR/NAND
• Programmable Real-Time Unit Subsystem (PRUSS) with two independent cores
• USB 2.0 OTG controller with integrated PHY and USB 1.1 OHCI host

Digital Signal Processor Dsp Applications

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

Digital Signal Processor Dsp Procurement Notes

Verify silicon revision and voltage grade against design requirements. Confirm package dimensions match the 17 mm x 17 mm 256-ball PBGA specification. Check for RoHS compliance status as manufacturing updates may occur. Ensure supply chain sources provide valid production data documentation.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high-performance DSP processing alongside real-time control via PRU cores. The 456 MHz variant requires a 1.3V core voltage, while the 375 MHz version uses 1.2V. Verify peripheral availability, as some functions are multiplexed. Ensure sufficient external memory bandwidth through EMIFA and EMIFB interfaces.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C674x family, which also includes the TMS320C6745. The C6747 distinguishes itself with a larger memory footprint (448 KB total RAM vs 320 KB), additional peripherals like LCD controller and RTC, and a higher pin count BGA package compared to the C6745's QFP package.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same family include other speed grades or package variants of the TMS320C6747. Verify compatibility if switching between 375 MHz and 456 MHz versions due to voltage differences.
