TMS320C6746BZWT3

Digital Signal Processor Dsp Overview

The TMS320C6746BZWT3 is a fixed- and floating-point digital signal processor based on the C674x VLIW architecture, manufactured by Texas Instruments. It operates at clock frequencies of 375 MHz (1.2V core) or 456 MHz (1.3V core). The device integrates 32 KB L1 program cache, 32 KB L1 data cache, and 256 KB L2 unified mapped RAM/cache. Key peripherals include a 10/100 Mbps Ethernet MAC, USB 2.0 OTG, PRU subsystem with two cores, and multiple serial interfaces such as UART, SPI, I2C, McASP, and McBSP. It utilizes a 361-ball PBGA package.

Digital Signal Processor Dsp Feature Summary

• Biometric Identification
• Low-End Machine Vision

Digital Signal Processor Dsp Procurement Notes

Verify the ordering suffix 'BZWT3' against the manufacturer's current datasheet to confirm specific package dimensions, temperature grade, and tape-and-reel specifications. Ensure compatibility with the required core voltage (1.2V for 375MHz or 1.3V for 456MHz) and I/O voltage levels (1.8V or 3.3V LVCMOS).

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring high-performance DSP processing alongside real-time control via the PRU subsystem. Consider the 361-ball BGA package constraints for PCB layout. Verify that the available GPIO pins meet interface requirements, as some peripherals share pin multiplexing resources.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C6746 family, which is code-compatible with the broader C6000 DSP platform. It combines the performance of the C64x+ core with the floating-point capabilities of the C67x+ core. The device is designed for low-power applications compared to other members of the TMS320C6000 platform.

Digital Signal Processor Dsp Replacement Considerations

Check for direct pin-to-pin replacements within the TMS320C6746 series, such as different speed grades or package variants (e.g., ZCE vs. ZWT). Ensure any substitute maintains the same C674x instruction set compatibility and peripheral configuration.
