TMS320C5515 Compatible with MT29C1G12MAACAEAMD-6 IT

Other Parts Discussed in Thread: TMS320C5515

Hello, I'm not to experienced with evaluating data sheets if someone with experience and knowledge could give me insight on whether Micron MT29C1G12MAACAEAMD-6 IT is compatible with the TMS320C5515 DSP, and if it isn't compatible please give me feedback on why its not compatible.

Thank you

  • Hi Lucas,

    Interesting part - a LPSDR and a NAND flash in same package. To me it looks like it will be compatible with C5515.

    The LPSDR looks just like a mobile SDRAM - supported by C5515 EMIF - mode register and extended mode regiister match those of a part known to be compatible.

    And the NAND looks ordinary..

    Are you planning to bootload from the NAND? There are additional bootloader requiremnets of the NAND flash. I will also forward this post to the bootloader guys.

    See SPRABD7B - Using the TMS320C5515/14/05/04 Bootloader

    2.2.2 NAND Flash
    The bootloader supports booting from a NAND Flash attached to any of the four EMIF chip-selects. The
    NAND Flash must use an 8-bit data bus, and its chip-enable and ready/busy signal must be connected to
    the C5515/14/05/04. The bootloader supports both small-block and large-block NAND Flash devices.
    The NAND Flash must use the SSFDC format. The bootloader reads the Boot Image Page Pointer (BIPP)
    from each of the first 256 physical pages until a non-0 value is found. If the BIPP on page-0 is 0, all other
    pages must start with the 3-byte signature 0xE9 0x00 0x00 in order to use the BIPP from that page. The
    BIPP is located in bytes 0xC4 through 0xC6 of the page.
    Once a valid BIPP is found, this value is used by the bootloader to determine which page contains the
    boot-image to load. Note that the boot-image cannot reside on the same page as the BIPP.
    See Table 2 for a list of supported NAND Device Ids.

    See Micron datasheet - Table 11: READ ID Parameters for Address 00h

    F1h, A1h, B1h IDs

    Keep in mind that the C5515 EMIF chip selects can address between 1MB and 8MB.

  • Hello Mark,

    Thank you for the information regarding this flash memory.

    We have built a prototype using this part and the NAND seems to be working fine as the boot device. We are on the verge of creating the release version for this device and I came across your post.

    Were you able to verify with the bootloader guys that in deed this NAND is recommend for boot?

    Thank you,

    Pedro
