TMS320C6747CZKB4

Digital Signal Processor Dsp Overview

The TMS320C6747CZKB4 is a fixed- and floating-point digital signal processor from the TMS320C674x family, manufactured by Texas Instruments. It integrates a high-performance C674x VLIW DSP core operating at clock rates up to 456 MHz, delivering up to 3648 MIPS and 2736 MFLOPS. The device features a two-level cache architecture with 32 KB L1P and 32 KB L1D caches, alongside a shared 256 KB L2 memory space. Key peripherals include a 10/100 Mbps Ethernet MAC, three McASP interfaces, multiple UARTs, and external memory interfaces (EMIFA and EMIFB). It is housed in a 256-pin FBGA package.

Digital Signal Processor Dsp Feature Summary

• Integrated 10/100 Mbps Ethernet MAC with MDIO module for network connectivity
• Three multi-channel audio serial ports (McASP) with FIFO buffers for audio applications
• Shared 256 KB L2 memory configurable as cache or mapped RAM

Digital Signal Processor Dsp Applications

• High-performance audio processing and codec design
• Industrial motor control and power conversion systems
• Medical imaging and ultrasound signal processing
• Wireless infrastructure baseband processing

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'CZKB4' against the official datasheet to confirm pinout, temperature range, and packaging details. Ensure compatibility with existing board layouts regarding the 256-BGA footprint and voltage requirements (1.2V core, 3.3V I/O). Check for end-of-life status or recommended replacements if sourcing new production units.

Digital Signal Processor Dsp Selection Notes

Select this component when a balance of high computational throughput and rich peripheral integration is required. The C6747 variant offers additional shared RAM compared to the C6745. Consider the 456 MHz maximum frequency for latency-sensitive applications. Verify that the software ecosystem, including CSL and BIOS support, aligns with the development environment.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C674x series, designed as a low-power alternative to the C6000 platform while maintaining high performance. It shares architectural similarities with other C674x devices but differs in memory size and specific peripheral configurations. The C6747 model specifically includes extra shared RAM accessible by host processors without impacting DSP performance.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the same family include the TMS320C6747BZKBD4 and TMS320C6747DZKBD4. These variants may differ in speed grades, packaging revisions, or manufacturing lots. Verify functional equivalence and pin compatibility before substitution.
