TMS320C6748BZCE3

Digital Signal Processor Dsp Overview

The TMS320C6748BZCE3 is a fixed- and floating-point digital signal processor based on the C674x VLIW architecture, housed in a 361-ball PBGA package with a 0.65-mm ball pitch. It operates at frequencies up to 456 MHz (at 1.3V core voltage) or 375 MHz (at 1.2V), delivering up to 3648 MIPS and 2746 MFLOPS. The device integrates a two-level cache memory system comprising 32KB L1P, 32KB L1D, and 256KB L2 unified RAM/cache. Key peripherals include an EDMA3 controller with 64 independent channels, USB 2.0 OTG and USB 1.1 OHCI interfaces, a 10/100 Mbps Ethernet MAC, SATA controller, and multiple serial communication ports.

• Machine Vision (Low-End)

Digital Signal Processor Dsp Procurement Notes

Verify the ordering suffix 'BZCE3' corresponds to the specific package variant (361-ball PBGA, 0.65-mm pitch) and temperature range defined in the datasheet. Confirm that the 'B' designation aligns with the intended commercial, extended, or industrial grade requirements for the application environment.

Digital Signal Processor Dsp Selection Notes

Select this component when high-performance floating-point processing is required alongside extensive connectivity options like SATA and USB 2.0. Ensure the design accommodates the 1.3V core voltage requirement for 456 MHz operation. Verify that the 361-ball BGA package fits the PCB layout constraints and thermal management strategy.

Digital Signal Processor Dsp Part Context

This part belongs to the Texas Instruments TMS320C6000 platform, specifically the C674x family. It combines the instruction set compatibility of C64x+ and C67x+ cores. The ZCE suffix indicates the 13 mm x 13 mm, 361-ball PBGA package with 0.65 mm pitch, distinct from the ZWT package which uses a 0.80 mm pitch.

Digital Signal Processor Dsp Replacement Considerations

Check for other C674x variants with different package pitches (e.g., ZWT for 0.80 mm pitch) if mechanical fitment differs. Ensure code compatibility with other C6000 series devices if migrating from older C64x or C67x models.
