TMS320C6747BZKB3

Digital Signal Processor Dsp Overview

The TMS320C6747BZKB3 is a fixed- and floating-point digital signal processor based on the TMS320C674x DSP core. It operates at clock frequencies of 375 MHz (1.2V) or 456 MHz (1.3V), delivering up to 3648 MIPS and 2736 MFLOPS. The device features a two-level cache architecture with 32 KB L1P, 32 KB L1D, and 256 KB L2 unified memory, plus an additional 128 KB shared RAM. Key peripherals include a 10/100 Mbps Ethernet MAC, USB 2.0 OTG, USB 1.1 OHCI, three McASPs, and a Programmable Real-Time Unit Subsystem. It is housed in a 256-ball PBGA package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific silicon revision associated with the 'B' suffix against the manufacturer's documentation. Confirm that the required operating voltage (1.2V or 1.3V) matches the design constraints for the target clock frequency. Ensure the 256-ball PBGA package footprint aligns with the PCB layout specifications.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring high-performance DSP processing alongside extensive connectivity options like USB OTG and Ethernet. The inclusion of 128 KB shared RAM makes it suitable for systems where external processors need direct memory access without impacting DSP performance. Consider the thermal characteristics of the PBGA package for heat dissipation requirements.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C6745/C6747 family of low-power digital signal processors. The C6747 variant is distinguished by its larger memory capacity and additional peripherals compared to the C6745. The ZKB suffix indicates the 256-ball PBGA package type, while the B suffix typically denotes a specific silicon revision or temperature grade within the production data release.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same family include the TMS320C6745, though it lacks the 128 KB shared RAM, LCD controller, and some USB/Ethernet capabilities. Other C6000 series devices may offer higher performance but require significant architectural adaptation.
