TMS320C6746EZWT4

Digital Signal Processor Dsp Overview

The TMS320C6746EZWT4 is a fixed- and floating-point digital signal processor based on the C674x VLIW architecture, manufactured by Texas Instruments. It operates at clock rates of 375 MHz (1.2V core) or 456 MHz (1.3V core), delivering up to 3648 MIPS and 2746 MFLOPS. The device integrates 32KB L1P cache, 32KB L1D cache, and 256KB L2 unified RAM/cache within a 361-ball NFBGA package (16mm x 16mm). Core voltages range from 1.0V to 1.3V depending on frequency, with 1.8V or 3.3V I/O options.

Digital Signal Processor Dsp Feature Summary

• C674x DSP core supporting IEEE single and double precision floating-point operations alongside fixed-point arithmetic.
• Integrated PRU Subsystem with two independent 32-bit RISC cores for deterministic real-time control.
• Comprehensive peripheral set including EMAC, USB 2.0 OTG, DDR2/mDDR controller, and multiple serial interfaces.
• Enhanced Direct Memory Access Controller (EDMA3) providing 64 independent channels for high-throughput data movement.

Digital Signal Processor Dsp Applications

• Currency inspection systems
• Biometric identification devices
• Low-end machine vision applications

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade required for the design; the EZWT4 suffix denotes the 456 MHz variant in the 16x16 mm NFBGA package. Confirm that the system power supply supports the necessary 1.3V core voltage for maximum performance. Ensure compatibility with the 361-ball 0.80mm pitch footprint during PCB layout.

Digital Signal Processor Dsp Selection Notes

Select this component when both high-performance DSP processing and deterministic real-time control are required in a single chip. The integrated PRUSS allows offloading time-critical tasks from the main DSP core. Consider the 456 MHz operating point if maximum throughput is needed, noting the associated increase in core voltage requirements compared to the 375 MHz version.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C674x family, which provides code compatibility with the broader C6000 DSP platform. It combines the computational power of the C64x+ core with the floating-point capabilities of the C67x+ core. The ZWT package variant specifically utilizes a 16mm x 16mm body size with a 0.80mm ball pitch, distinguishing it from the smaller ZCE package.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6748EZWT4 serves as a higher-performance alternative within the same family, offering identical pinouts and software compatibility but with enhanced peripheral counts and potentially different memory configurations. Verify thermal dissipation requirements when upgrading to higher-speed variants.
