TMS320C6748EZWTD4

Digital Signal Processor Dsp Overview

The TMS320C6748EZWTD4 is a fixed- and floating-point digital signal processor from Texas Instruments, based on the C674x VLIW architecture. It operates at clock frequencies up to 456 MHz when supplied with a core voltage of 1.3 V, delivering up to 3648 MIPS and 2746 MFLOPS. The device integrates a two-level cache memory system comprising 32 KB of L1 program RAM/cache, 32 KB of L1 data RAM/cache, and 256 KB of unified L2 mapped RAM/cache. Additionally, it includes 128 KB of shared RAM accessible by other system hosts. The component utilizes a 361-ball plastic ball grid array (PBGA) package with a 0.80-mm ball pitch.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'T4' indicates tape-and-reel packaging configuration as per manufacturer standards. Confirm the operating temperature range corresponds to the commercial or industrial grade required for the target application environment. Ensure power supply rails match the specified 1.2V–1.0V core and 1.8V/3.3V I/O requirements during board design.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high-performance DSP processing with integrated connectivity options like Ethernet and USB. The ZWT package variant is suitable for designs accommodating a 16x16 mm footprint. Consider the 456 MHz speed grade if maximum computational throughput is necessary, noting the associated 1.3 V core voltage requirement compared to the 375 MHz 1.2 V variant.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C6748 family, which combines a C674x DSP core with an ARM926EJ-S processor in some system configurations, though the DSP core itself is the primary processing unit described here. It is part of the TMS320C6000 platform, offering code compatibility with C64x+ and C67x+ instruction sets. The device supports secure boot features using SHA-1/SHA-256 and AES-128 for intellectual property protection.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6748EZWT4 is a pin-compatible alternative within the same package family. Other speed grades such as the 375 MHz version are available but require different core voltage settings. Verify peripheral availability as pin multiplexing may restrict simultaneous use of all interfaces depending on the specific configuration.
