TMS320C6745DPTP4

Digital Signal Processor Dsp Overview

The TMS320C6745DPTP4 is a fixed- and floating-point digital signal processor based on the TMS320C674x DSP core, manufactured by Texas Instruments. It operates at maximum clock frequencies of 375 MHz (1.2V) or 456 MHz (1.3V). The device features a two-level cache architecture comprising 32KB L1 program RAM/cache, 32KB L1 data RAM/cache, and 256KB unified L2 mapped RAM/cache. It includes an Enhanced Direct Memory Access Controller 3 (EDMA3) with 32 independent channels. Key peripherals include a 10/100 Mbps Ethernet MAC, three UARTs, two SPIs, two I2C interfaces, two multichannel audio serial ports, and external memory interfaces for SDRAM and asynchronous memories.

Digital Signal Processor Dsp Procurement Notes

Verify the specific silicon revision and operating voltage requirements (1.2V for 375 MHz, 1.3V for 456 MHz) against the system design. Confirm that the HLQFP-176 package thermal characteristics meet the application's heat dissipation needs. Ensure compatibility with TI DSP/BIOS and Chip Support Library software tools for development.

Digital Signal Processor Dsp Selection Notes

Select this component when high-performance fixed- and floating-point processing is required in a low-power form factor. The TMS320C6745 is suitable for applications needing integrated connectivity like Ethernet and USB 2.0 Full-Speed, but lacks the LCD controller, HPI, and additional McASP found in the TMS320C6747 variant. Verify peripheral multiplexing constraints if multiple interfaces are used simultaneously.

Digital Signal Processor Dsp Part Context

The TMS320C6745DPTP4 belongs to the TMS320C674x family, which is code-compatible with the C6000 DSP platform. It combines the performance of the C64x+ core with the floating-point capabilities of the C67x+ core. The 'DPTP4' suffix indicates the specific speed grade, temperature range, and 176-pin PowerPAD TQFP package configuration.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6747 is a pin-compatible alternative within the same family that offers additional peripherals such as an LCD controller, Host Port Interface (HPI), and an extra McASP, along with higher-speed USB support. However, it uses a different 256-ball PBGA package.
