TMS320C6746AZWT3

Digital Signal Processor Dsp Overview

The TMS320C6746AZWT3 is a fixed- and floating-point digital signal processor based on the C674x core, housed in a 361-ball NFBGA package with a 16.00 mm x 16.00 mm body size and 0.80-mm ball pitch. It operates at clock frequencies of 375 MHz (1.2 V) or 456 MHz (1.3 V). The device features a two-level cache architecture comprising 32 KB L1P, 32 KB L1D, and 256 KB L2 unified RAM/cache. Key peripherals include an EMAC, USB 2.0 OTG, PRUSS, and multiple serial interfaces.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., A3 for 375 MHz or A4 for 456 MHz) against the required operating frequency and voltage. Confirm the package variant matches the PCB footprint requirements. Check RoHS compliance status and moisture sensitivity level before assembly.

Digital Signal Processor Dsp Selection Notes

Select the 375 MHz version for 1.2 V core operation or the 456 MHz version for 1.3 V core operation. Ensure the design supports the required I/O voltage levels (1.8 V or 3.3 V LVCMOS). Verify that the available GPIO pins meet the multiplexing requirements for the selected peripheral set.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C674x family, which provides code compatibility with the C6000 DSP platform. It combines the performance of the C64x+ core with the floating-point capabilities of the C67x+ core, offering a low-power solution for mixed-signal processing applications.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6745 and TMS320C6743 are pin-compatible members of the same family. Verify peripheral availability differences, such as the presence of the PRUSS subsystem or specific memory sizes, when substituting these parts.
