TMS320C6748EZCE3

Digital Signal Processor Dsp Overview

The TMS320C6748EZCE3 is a fixed- and floating-point digital signal processor from Texas Instruments, featuring a C674x VLIW DSP core operating at 375 MHz. It delivers up to 3648 MIPS and 2746 MFLOPS performance. The device integrates a two-level cache architecture comprising 32KB L1P, 32KB L1D, and 256KB L2 unified RAM/cache, alongside 128KB of shared memory. Key peripherals include an EDMA3 controller with 64 channels, dual external memory interfaces (EMIFA and DDR2/mDDR), USB 2.0 OTG, Ethernet MAC, SATA, and multiple serial communication ports. It is housed in a 361-ball NFBGA package with a 0.65-mm ball pitch.

Digital Signal Processor Dsp Procurement Notes

Verify the ordering suffix 'ZCE' corresponds to the 361-ball NFBGA package with a 0.65-mm ball pitch and 13.00 mm x 13.00 mm body size. Confirm the temperature grade matches the required commercial, extended, or industrial specifications. Ensure the specific frequency variant (375 MHz) aligns with system timing requirements.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring high-performance DSP processing with integrated connectivity options like Ethernet and USB. The 375 MHz speed grade operates at a 1.2V core voltage. Consider the available pin count and peripheral multiplexing if interfacing with complex external buses or multiple storage devices simultaneously.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C6748 family within the TI C6000 platform. It combines the instruction set compatibility of C64x+ and C67x+ cores. The ZCE suffix specifically denotes the smaller 0.65-mm pitch PBGA package compared to the ZWT variant which uses a 0.80-mm pitch.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same package and pinout are limited within the C6748 family itself. Other C6000 series processors may offer code compatibility but require verification of peripheral availability and package dimensions.
