TMS320C6748BZCEA3E

Digital Signal Processor Dsp Overview

The TMS320C6748BZCEA3E is a fixed- and floating-point digital signal processor based on the C674x VLIW architecture. It operates at frequencies up to 456 MHz, delivering up to 3648 MIPS and 2746 MFLOPS. The device integrates a two-level cache memory structure comprising 32KB L1P, 32KB L1D, and 256KB L2 unified mapped RAM/cache. Key peripherals include an EDMA3 controller with 64 independent channels, a 10/100 Mbps Ethernet MAC, USB 2.0 OTG, SATA, and multiple serial interfaces. It features a 361-ball PBGA package with a 0.65-mm ball pitch.

Digital Signal Processor Dsp Procurement Notes

Verify that the ordering suffix 'BZCEA3E' corresponds to the specific package, temperature grade, and product status defined in the manufacturer's current documentation. Confirm the exact frequency rating (375 MHz or 456 MHz) associated with the voltage requirements for the specific unit received.

Digital Signal Processor Dsp Selection Notes

Select this component when high-performance DSP processing is required alongside direct connectivity to mass storage via SATA. Ensure the design accommodates the 361-ball PBGA package dimensions and utilizes the appropriate core supply voltage (1.2V for 375 MHz or 1.3V for 456 MHz). Verify peripheral pin multiplexing constraints if multiple interfaces are active simultaneously.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C6000 platform family, specifically the C674x series. It combines the instruction set compatibility of C64x+ and C67x+ cores. The 'ZCE' designation indicates the 13 mm x 13 mm, 361-ball plastic ball grid array package with a 0.65-mm pitch.

Digital Signal Processor Dsp Replacement Considerations

Check for code compatibility with other C6000 series processors such as the TMS320C6747 or TMS320C6745. Verify pin-to-pin compatibility if substituting within the same package type, noting differences in peripheral availability or clock speeds.
