TMS320C6748BZCED4

Digital Signal Processor Dsp Overview

The TMS320C6748BZCED4 is a fixed- and floating-point digital signal processor based on the C674x VLIW architecture, operating at frequencies up to 456 MHz. It delivers up to 3648 MIPS and 2746 MFLOPS performance. The device integrates a two-level cache memory system comprising 32KB L1P, 32KB L1D, and 256KB L2 unified mapped RAM/cache. Key peripherals include an Enhanced Direct Memory Access Controller 3 (EDMA3) with 64 independent channels, a 10/100 Mbps Ethernet MAC, USB 2.0 OTG, SATA, and multiple serial interfaces. It features a Programmable Real-Time Unit subsystem with two PRU cores and supports secure boot via AES-128 encryption.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade and voltage configuration required for the application. The 'B' suffix in the part number typically denotes a specific temperature range or speed bin; confirm this against the manufacturer's current ordering guide as specifications may vary between commercial, extended, and industrial grades. Ensure the 0.65-mm pitch PBGA package compatibility with the target PCB footprint.

Digital Signal Processor Dsp Selection Notes

Select this component when high-performance DSP processing is required alongside real-time control capabilities provided by the PRU subsystem. The device is suitable for applications needing robust connectivity options such as Ethernet, USB 2.0 OTG, and SATA. Consider the available 448KB of on-chip RAM and the flexible L2 cache partitioning for memory-intensive algorithms.

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 the C64x+ and C67x+ families. The ZCE package indicates a 361-ball plastic ball grid array with a 0.65-mm ball pitch, measuring 13.00 mm x 13.00 mm.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6748ZWT is a pin-compatible alternative using a 16.00 mm x 16.00 mm package with a 0.80-mm ball pitch. Other members of the TMS320C6000 platform may offer code compatibility but differ in peripheral sets and performance metrics.
