TMS320F28P650DK: Project Design Review

Venkatesh R
Prodigy 10 points
Part Number: TMS320F28P650DK
Other Parts Discussed in Thread: TMS320F28377D-EP, LAUNCHXL-F28P65X, BOOSTXL-DRV8323RS

Tool/software:

I have designed three phase inverter for a military application, and in my design I used texas instrument Microcontroller (F28P650DK7PTP from the family TMS320F28P650DK) and few other TI components. Please support us by reviewing the hardware design and software design.

1. Whether this MCU can support for military application or any other similar MCU with mil grade available?

Please provide your support asap.

    For this class of device we don't currently have an "enhanced product or EP" variant.  The closest device we have is TMS320F28377D-EP, but it may not have several of the features of the F28P65x device you have already looked at.

    In terms of applicability, I would need to understand what the military requirement is in particular for the MCU.  Given the ASIL/SIL safety certificate, I would say that the device should be very robust in a military application, but that may not be the biggest concern you have.

    If there are such things as single source fab, or ability to order all devices from the same lot, etc, then this device will not meet that requirement.  We also see military/avionics require gold bond wire, which this device also does not have(the EP device does have this).

    So, in general, military customers would look to have a -EP device, as it typically satisfies the continuity of supply requirements that we see for military applications, in addition to the gold bond wire.  If these aspects are not necessary, then it really depends on the end application and if the ASIL/SIL aspects of this device translate to the system requirement for safety.

    Since it is a prototype development, we are not designing the hardware and testing the product with military grade components, but the application must be work on with our condition (Eg., Supplied current, supplied voltage, temperature, current sensing etc.,). Can we get the support for design verification and discuss the further updates based on TI components? If any details or procedure to follow, please give me the mail. so that I can follow the steps and it will help us for further development.

    We have selected the microcontroller TMS320F28P650DK (specifically the part number F28P650DK7PTP) for our motor control development and have already developed the firmware based on our application requirements.

    1. Development Kit Compatibility:
      Can we use the LAUNCHXL-F28P65X development kit for our firmware development and testing?
      Or is there a dedicated development kit specifically designed for the F28P650DK7PTP microcontroller? Alternatively, is this kit intended to support all members of the TMS320F28P65x family?

    2. Additional Support Boards:
      Beyond our custom driver board and control board, are there any other evaluation or support boards recommended or required for initial development or bench testing?

    3. Bench-Level Software Validation Setup:
      For bench-level software validation, would using BOOSTXL-DRV8323RS (motor driver board) along with the LAUNCHXL-F28P65X (control board) be sufficient for basic motor control testing?

    Thanks,

    Venkatesh R

    You are correct, the LAUNCHXL-F28P65X is intended to support all members of the P65x family.  Our strategy is to produce EVM kits with the superset part number that can be used to emulate the others.

    I will add, that by using the MCUCNF register https://www.ti.com/document-viewer/lit/html/SPRUIZ1B#GUID-0A8D381F-106E-46F5-820C-670FD305D89F/TITLE-SPRUIN7SPRUI339519 you can make a superset TMS320F28P650DK9 look like the F28P650DK7 so you can make sure the code will work correctly on the final part number

    The LaunchPad only supports a subset of the pins on this device.  I would check the pinout to make sure you can access all the signals that important for your end application.  Alternatively we also have our controlCARD platform https://www.ti.com/tool/TMDSCNCD28P65X which brings out most/all of the signals on the device.  If you need more than the Launch pad provides, or want to future proof your development the controlCARD would be the way to go, at least for HW development.  A possible strategy, since the controlCARD costs a bit more than the LP, would to have 1 controlCARD for the HW aspect, and a few LPs for SW development.

    Let me ask some of the other team members here, that BOOSTXL-DRV8323RS is one of our original motor booster packs, I want to make sure it will work well with the F28P65x.
