MPN： TMS320C6748EZWT4 ✓ 啟用中TMS320C6748EZWT4 概覽
A digital signal processor is a specialized semiconductor that executes mathematical operations in parallel-friendly architectures. Unlike a general-purpose processor, a DSP is optimized for filtering, transforms, signal analysis, modulation, and other repetitive calculations on streaming data. The C674x core combines fixed-point and floating-point processing, allowing control-oriented integer workloads and precision-oriented floating-point algorithms to share one platform.
Key verified characteristics include a C674x processor core, one core, a 456 MHz maximum clock, 64-bit data-bus support, 8-bit and 16-bit data-bus support, 128 kB data RAM, and SATA connectivity. The verified distributor listing also identifies the part as a 361-pin NFBGA device. Detailed electrical limits, memory maps, peripheral inventories, and package dimensions were not included in the supplied source data and require consultation of the manufacturer datasheet.
The C674x architecture is appropriate for high-throughput signal-processing workloads requiring deterministic execution. Its floating-point capability is valuable for filters, transforms, control loops, audio processing, and communications algorithms, while fixed-point support can reduce resource use in stages where integer arithmetic is sufficient. Integration with an applications-processor-oriented platform helps OEMs consolidate real-time processing and high-level control tasks.
Typical applications include industrial control, communications infrastructure, audio and signal processing, test and measurement, and embedded systems that process continuous sensor or network data. SATA support can be relevant to systems that exchange data with storage devices, although the exact interface implementation and software requirements must follow the TI design documentation. A C674x development kit may also be used to develop and validate application firmware before hardware integration.
For a new design, verify every power rail, clock, boot mode, memory interface, and high-speed serial connection against the official datasheet before layout begins. The 361-pin NFBGA requires fine-pitch PCB escape routing, controlled power delivery, and careful thermal design. Software should also account for initialization order, cache and memory behavior, peripheral pin multiplexing, and the processor's interrupt requirements.

典型應用
TMS320C6748EZWT4 適用於 6 應用s: Industrial Signal Conditioning, Communications Infrastructure, Audio and Voice Processing, Test and Measurement Equipment, Storage and Data Acquisition, Embedded Control and Monitoring.
Industrial Signal Conditioning
The TMS320C6748EZWT4 fits industrial signal-conditioning prototypes that need the 456 MHz C674x core and 3648 MIPS throughput for filtering, transforms, and real-time data reduction. Its fixed- and floating-point capability allows one platform to handle sensor streams with different numerical requirements. The 128 kB data RAM can support intermediate working buffers, but a production design must confirm external memory needs, deterministic interrupt behavior, and the required peripheral mix. Use the TMDXLCDK6748 for early firmware validation, then review TI's electrical and package guidance before committing the 361-pin NFBGA layout.
推薦
Communications Infrastructure
The TMS320C6748EZWT4 is appropriate for communications infrastructure work involving real-time filtering, modulation, packet processing, or other C674x-compatible algorithms. The 456 MHz clock and 3648 MIPS rating provide a clear throughput target for embedded DSP pipelines, while the verified SATA feature can support storage-oriented data movement where the surrounding interface is designed correctly. Engineers must budget external memory and packet buffers, validate high-speed peripheral routing, and confirm boot and firmware assumptions. A communications design should use TI's official device documentation rather than treating a generic DSP substitution as equivalent.
推薦
Audio and Voice Processing
The C674x floating-point DSP is suitable for audio and voice prototypes requiring high-throughput filtering, spectral analysis, mixing, or noise-processing algorithms. Its 456 MHz operating point supports real-time workloads, while 128 kB data RAM can accommodate compact sample and coefficient buffers. The application still needs a verified audio interface, memory architecture, clocking plan, and deterministic task schedule. Because the supplied data does not specify audio peripherals or codec integration, engineers should treat the DSP as the processing core and select external interface hardware separately. TI's TMDXLCDK6748 can support initial algorithm and firmware development.
推薦
Test and Measurement Equipment
The TMS320C6748EZWT4 can serve as the processing engine in test and measurement equipment that performs real-time acquisition math, digital filtering, calibration, or spectral analysis. The fixed- and floating-point instruction support is useful when a product must combine high-throughput integer operations with more demanding numeric calculations. A 456 MHz clock and 128 kB data RAM provide a defined baseline, but instrumentation accuracy depends on external converters, clocking, memory, calibration data, and carefully controlled analog front ends. The supplied data does not identify a dedicated measurement peripheral set, so interface selection must be verified against the complete datasheet and application requirements.
推薦
Storage and Data Acquisition
The verified SATA feature makes the TMS320C6748EZWT4 a candidate for embedded systems that acquire data and exchange it with storage. The C674x core can perform preprocessing, compression, indexing, or control tasks while the system moves data through a validated storage interface. Designers should assess bandwidth, buffering, error handling, boot media, filesystem behavior, and power-management behavior as complete system requirements rather than assuming SATA alone determines application suitability. The supplied source set does not specify SATA signaling details, PHY requirements, or supported storage capacities, so those points must come from the official TI documentation and board design guides.
推薦
Embedded Control and Monitoring
The TMS320C6748EZWT4 can be evaluated for embedded monitoring systems that combine deterministic signal processing with higher-level application logic. Its C674x core supports fixed- and floating-point operations, while the 456 MHz clock can shorten execution time for control-oriented algorithms compared with a lower-rate implementation. Real deployment still requires verified I/O assignments, interrupt latency behavior, watchdog or recovery strategy, environmental limits, and production test coverage. The 361-pin NFBGA footprint should be treated as a major layout commitment. Use the processor's official package pinout and electrical tables, then compare software support and supply availability before selecting it for a long-life design.

主要差異化特點
- Higher verified clock rating than the compared BZWTA3 (對比TMS320C6748BZWTA3)
- C674x fixed- and floating-point processing position (對比TMS320F28027DAS)
- Verified SATA connectivity in the product listing (對比TMS320C6748BZWTA3)
- Explicit 128 kB data RAM reference in the comparison (對比TMS320C6748BZWTA3)
設計說明
Estimated: the verified package is NFBGA-361 with a 0.65 mm class of fine-pitch geometry inferred only from the package family description; confirm the exact ball pitch and land pattern in the official TI package drawing before routing. Use a stack-up with short escape paths, continuous ground reference planes, and symmetrical power distribution. Validate escape-routing manufacturability and via-in-pad assumptions with the PCB fabricator.
The supplied comparison data lists a 1.2 V operating supply for the device, but it does not include every internal rail, tolerance, current limit, or sequencing requirement. Follow the official TI recommended power topology rather than applying the single listed value to the entire board. Place decoupling capacitors at the appropriate supply balls, preserve current-return paths, and use instrumentation to verify startup and steady-state behavior on first prototypes.
The C674x processor is a high-performance embedded DSP, so clock quality, memory routing, peripheral interfaces, and boot signals must be treated as a complete signal-integrity problem. Match interfaces according to the official electrical tables, keep sensitive nodes away from noisy switching paths, and route high-speed signals over uninterrupted reference planes. The supplied data does not provide rise-time or channel-length limits, so those values must be taken from TI documentation and validated with measurements.
Do not infer pin compatibility from the C674x family name alone. The verified source data identifies several related devices but does not provide complete pin maps, memory configurations, boot behavior, or electrical limits for each alternative. Before substitution, compare the complete datasheet, package drawing, boot ROM expectations, peripheral multiplexing, voltage rails, and software support. Treat the 361-ball footprint as a board-level commitment rather than a generic BGA interchange.
合規資訊
The supplied verified data does not include explicit RoHS, REACH, lead-free, halogen-free, or conflict-minerals statements for TMS320C6748EZWT4. AEC-Q100 is marked not_applicable because this is an applications processor/DSP rather than an explicitly automotive-qualified device in the supplied data.
