TMS320C6746BZWT4

Digital Signal Processor Dsp Overview

The TMS320C6746BZWT4 is a fixed- and floating-point digital signal processor from the C674x family, manufactured by Texas Instruments. It operates at clock rates of 375 MHz (1.2V core) or 456 MHz (1.3V core). The device integrates 32KB L1P cache, 32KB L1D cache, and 256KB L2 unified RAM/cache. Key peripherals include an EMAC, USB 2.0 OTG, PRUSS, and multiple serial interfaces. It is housed in a 361-ball NFBGA package with dimensions of 16mm x 16mm.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade (375 MHz vs 456 MHz) required for the design, as this dictates the core voltage settings (1.2V vs 1.3V). Confirm that the 16mm x 16mm NFBGA package footprint matches the PCB layout. Ensure compatibility with the 1.8V or 3.3V LVCMOS I/O standards, excluding USB and DDR2 interfaces which have different requirements.

Digital Signal Processor Dsp Selection Notes

Select the TMS320C6746BZWT4 when high-performance DSP processing is needed alongside rich connectivity options like Ethernet and USB OTG. The choice between 375 MHz and 456 MHz versions depends on computational throughput requirements and thermal management capabilities. Consider the PRUSS subsystem if deterministic real-time control tasks are required alongside DSP functions.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C674x series, designed as low-power applications processors. It combines the performance of the C64x+ core with the floating-point capabilities of the C67x+ core. The 'B' suffix typically denotes a specific temperature range or revision within the commercial/extended/industrial offerings, while 'ZWT' specifies the 361-ball NFBGA package type.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements within the same package may include other variants of the TMS320C6746 series (e.g., TMS320C6746ZCE for smaller package, or different speed grades). Cross-family migration to TMS320C667x requires significant architectural changes. Verify code compatibility with the C6000 platform when considering alternatives.
