Key Features
- Combined fixed-point and floating-point arithmetic engine in a single 32-bit DSP core, enabling both integer signal processing and real-number algorithm execution without external FPU hardware
- 16-bit external data bus with 23-bit address bus, providing access to up to 8 MB of external memory for DSP firmware and data buffers in embedded signal processing systems
- Boundary scan (JTAG) support for in-system testing and debugging, reducing board bring-up time and enabling production test coverage of all 361-ball NFBGA connections
- Compact 361-ball NFBGA package balancing I/O density and PCB footprint for DSP-intensive embedded computing boards in industrial and communications applications
Applications
TMS320C6748EZWT4 is well-suited for embedded real-time signal processing tasks such as audio processing, motor control algorithms, and software-defined radio modem functions in industrial and communications equipment. Its combined fixed/floating-point DSP core allows engineers to run both integer filtering stages and floating-point FFT routines on the same device, reducing system component count in instrumentation and test equipment. The JTAG boundary scan capability also makes it a strong fit for production-testable boards in medical imaging, radar front-ends, and telecommunications infrastructure.

Frequently Asked Questions
What arithmetic formats does TMS320C6748EZWT4 support, and how does this affect DSP algorithm flexibility?
TMS320C6748EZWT4 supports both fixed-point integer and IEEE 754 floating-point arithmetic within its 32-bit DSP core. This dual-format capability allows developers to run fixed-point FIR filters at maximum efficiency alongside floating-point FFT routines in the same firmware image, avoiding the need for a separate FPU coprocessor or two-chip solution—an important cost and board-area advantage for embedded signal processing designs.
What external memory interface does TMS320C6748EZWT4 provide, and how much external memory can it address?
TMS320C6748EZWT4 offers a 16-bit external data bus paired with a 23-bit address bus, enabling direct connection to up to 8 MB of external SRAM, Flash, or SDRAM. For DSP applications that require large coefficient tables or audio sample buffers—such as 48 kHz multi-channel audio processing or multi-band equalizer firmware—this external memory interface provides the capacity needed without off-chip address decoders.
How does JTAG boundary scan support on TMS320C6748EZWT4 benefit high-volume PCB production testing?
The built-in JTAG boundary scan (IEEE 1149.1) capability allows automated test equipment to drive and sense all 361 BGA pins through the scan chain without physical probe access, detecting opens, shorts, and solder defects in production. This can reduce board test time by up to 50% compared to in-circuit test probing on densely packed BGA assemblies, and it supports firmware debug and in-system programming through the same 4-wire JTAG interface.
For a software-defined radio modem requiring floating-point FFT processing, how does TMS320C6748EZWT4 compare to a pure fixed-point DSP?
A pure fixed-point DSP requires manual Q-format scaling and dynamic range management for floating-point FFT algorithms, typically adding 20–30% more development time. TMS320C6748EZWT4's native floating-point engine processes 32-bit IEEE 754 values directly, allowing standard C math libraries and MATLAB-generated code to run without manual scaling—reducing modem firmware development cycles while maintaining real-time throughput at the device's 30 MHz maximum clock.
