TMS320C6748 DSP Chips, Core & Development Boards
TMS320C6748 DSP: select the exact silicon or development platform
This collection centers on TMS320C6748-family digital signal processing components: loose 361-ball BGA ICs, compact core boards and larger development-board assemblies. C6748 is a C674x fixed- and floating-point processing platform used in embedded signal-processing work; a packaged IC, a populated core board and a development kit are different purchase types. The collection also currently contains a 28BYJ-48 stepper-motor kit and a multi-device chip listing with other TI processors. Neither should be mistaken for an automatically included C6748 accessory or chip. Start with the exact selected variant and its physical contents, then check the manufacturer's device documentation and the individual board schematic.
Loose C6748 DSP devices: suffix and BGA matter
Listings show single-piece TMS320C6748EZWTD4, TMS320C6748EZWT, TMS320C6748EZCEA3 and TMS320C6748BZWT order-code strings, frequently described as 361-ball LFBGA/NFBGA devices. The complete manufacturer orderable code, not the shorthand “C6748,” controls package, silicon/revision, speed and temperature details. Some source descriptions misclassify a C6748 part as a voltage regulator or generic logic device. Those supplier category tags do not change the underlying part identity, but the listing alone also does not validate every suffix or ball-map claim. Compare the exact marking and ordering guide, pin/ball assignment, land pattern, soldering process, power sequencing, boot modes, memory interfaces and applicable errata before assigning an IC to a PCB. A loose BGA requires a compatible PCB and assembly process; it is not a ready-to-run computer or an evaluation kit.
A separate “5PCS” listing displays TMS320C6748EZWT4, TMS320DM642AZDK6 and TMS320F28377DZWTT as alternative Color selections. Select the exact part you need: the listing headline does not establish that each order contains all three types, nor that a DM642 digital-media processor or F28377D C2000 controller can replace C6748. Its generic description cites a different TMS320C6657 model number, so treat that mismatch as a reason to verify the actual orderable code, selected pack count and supplied marking rather than assuming the details all describe the same chip. “Original,” “genuine,” “new” and claimed stock are upstream assertions, not independent traceability or authenticity checks.
Core boards: a processor plus the board's supporting circuit
Chuanlon industrial C6748 core-board options read “256mb 512mb nand,” “128mb 128mb lock,” and “128mb 128mb nand.” These strings appear to distinguish memory or configuration packages, but the listing provides no technical breakdown. In particular, “lock” is not a documented memory type here, and lowercase “mb” does not reliably distinguish megabits from megabytes. Confirm DDR capacity, flash technology, boot settings and whether a carrier is supplied for the exact option. Do not infer that all memory variants are pin-compatible or contain the same storage chips.
Another RK6748 core-board description claims a TMS320C6748 running up to 450 MHz, 1 Gbit DDR, 64 Mbit NOR flash, 128 Mbit SPI flash and 1 Gbit NAND flash, with a 60 × 45 mm six-layer PCB and 150 expansion pins. Its text also mentions camera/video, two audio streams, USB OTG, SD, 100-Mbit Ethernet, serial ports, I2C EEPROM, EMIF and GPIO, plus a 5 V interface and CCS 5.5 workflow. These are supplier-described board-level details, not guaranteed features of every C6748 chip or every core board here. Check a specific revision's schematic, connector map, fitted devices and supported software before planning a camera, audio or Ethernet design. A board's 5 V supply input does not make its DSP GPIO 5 V tolerant. An unelaborated “Core Board For Learning Image Audio Camera Processing” listing supplies no reliable board specification beyond its name; obtain the actual fitted chip and schematic before treating it as equivalent to RK6748.
Development boards and what a kit includes
Chuanlon and BoMaSChuanlon C6748 industrial development-board pages expose alternatives labeled “7inch lcd 800X480,” “128mb 128mb lock,” “256mb 512mb,” and “128mb 128mb”; one page also has a shipping-origin option. A screen-labeled option could represent a display rather than the same baseboard with an included screen. The listings do not unambiguously define each combination. Confirm whether the chosen option contains a C6748 core board, carrier board, power adapter, LCD, camera, cables or debug probe. Do not convert the listed memory numbers into guaranteed installed capacity without a bill of materials.
The RK6748 development-board listing is more explicit: supplier text describes a kit with core board, bottom board, 5 V supply, serial/network/USB OTG/USB mini/audio cables, and expressly excludes emulators, LCD screens and cameras. Its text cites up to 450 MHz and DDR/NOR/NAND/SPI flash resources, with audio/video, USB, SD, Ethernet, serial, EMIF and GPIO interfaces. Confirm the board revision, connector breakout and installed parts if these features are decisive. Another “1PCS original genuine development board/learning board” listing gives no usable device-level configuration; its 90-day returns and refund language is supplier copy, not a replacement for the store's own policy or technical validation.
Software, debugging and system integration
- Match the hardware stage: a loose 361-ball IC is for PCB assembly; a core board typically needs a compatible carrier or breakout to expose interfaces; a development board provides a wider set of onboard connectors. Neither a core board nor a development board should be described as a single unpackaged DSP chip.
- Check the exact electrical design: separate the external board supply from the processor's internal and I/O rails. Validate reset and power sequencing, clock source, boot straps, DDR timing, EMIFA/EMIF sharing, GPIO multiplexing, codec/converter voltage domains and protection against input overvoltage. Use the actual board schematic and current manufacturer specifications, not another seller's pinout.
- Plan the processing chain: camera, audio and image use cases require matching sensor/codec interfaces, data bandwidth, memory capacity and throughput, plus application software. The presence of uPP or EMIFA in a title is not proof those signals are wired to the connector or free from conflicts on a particular board.
- Validate development tools: supplier descriptions mention CCS 5.5 and support for multiple emulators. Verify the exact C6748 target, JTAG header and voltage, emulator firmware, driver, OS and current software support before ordering. A compatible debugger is not automatically included unless the selected product explicitly says so.
- Qualify manufacturing and sourcing: compare ordering suffix, footprint, moisture and handling requirements, date/lot marking and device documentation. Marketing claims of original stock or quality do not establish provenance, certifications or guaranteed lifecycle.
Related listings with different functions
The 28BYJ-48 + ULN2003 product is a 5 V stepper-motor and driver-board kit for a separate motion-control project, not a C6748 board. Its selector offers “3 set” versus “5 set,” while the description specifically lists five motors and five drivers; verify the selected three-set contents rather than assuming the five-set description applies to both. The TMS320DM642 and TMS320F28377D alternatives in the multi-chip listing belong to different processing families. Keeping those listings in this collection does not imply pin, firmware or development-tool interchangeability with C6748.
Frequently asked questions
Does a C6748 BGA listing include a breakout or programmer? No such bundle is established. The single-chip listings identify packaged ICs; check each product's stated contents for anything additional.
Are EZWTD4, EZWT, EZCEA3 and BZWT identical parts? Do not assume so. The full orderable suffix and manufacturer documentation determine the relevant package, grade and revision; do not choose by the shortened C6748 name alone.
Does “256mb 512mb nand” guarantee 256 MB DDR and 512 MB NAND? The option text does not define units or the installed memory bill of materials. Request the selected board's schematic or configuration table.
Is the 7-inch LCD included with every development board? No. It is a separate variant label on some pages, and the RK6748 development-kit text explicitly excludes LCD screens. Confirm selected package contents.
Does the RK6748 kit include an emulator or camera? Its description expressly excludes emulators, LCD screens and cameras. Check the product version and selected order before planning to debug or capture video.
Can I replace C6748 with DM642 or F28377D because they appear in one listing? No drop-in compatibility is established. These are alternative chip choices with different architectures, packages and intended software/hardware workflows.
Is the 28BYJ-48 motor kit a C6748 accessory? It is an unrelated stepper-motor/ULN2003 bundle. Its presence here does not guarantee electrical integration with any DSP board.
This guide reflects the current mixed collection without changing its product membership. For a production design, validate the exact selected device marking, current manufacturer datasheet and errata, board revision and BOM, and the purchased kit's explicitly listed contents.
