DLP4500: Question about VID&PID and Flash Device ID

Part Number: DLP4500
Other Parts Discussed in Thread: DLPC350

Dear TI experts,

        I have few questions regarding the VID&PID, as well as the Flash Device ID.

       1. Is the VID and PID unique for every single DLP4500 EVM?

        2. I notice that in DLPC350_api.cpp, there is a function called DLPC350_GetFlashDevID, is that flashDevID an unique number for DLP4500EVM?

Thanks,

Raymond

  • Hello Raymond,

    Welcome to DLP forum and thank you for your interest in DLP technology.

    For  DLP4500 EVM, the USB Vendor ID (VID) is 0x0451 and the Product ID (PID) is 0x6401. It is not unique for each EVM.

    I will get back to you on flashDevID.

    regards,

    Vivek

  • Hi Raymond, 

    The FlashDevID depends on the Parallel Flash Chip that is used on the LCR4500. A particular model of Parallel Flash Chip will have a particular FlashDevID across all the copies made. So yes, multiple LCR4500s should have the same FlashDevID, unless & until the flash chip used is different. 

    Thanks & Regards,
    Hirak.
