TMS570 NAND FLASH

Other Parts Discussed in Thread: TMS570LC4357, HALCOGEN

Hi Everyone,

I am using TMS570LC4357,and I want drive a nand flash(K9WAG08U1B-PIB0)。 Is there an example?

Regards.

  • Hi,

    You can use the available asynchronous memory chip selects (EMIF_nCS2, 3, 4) to access the external NAND flash memory. There are some constraints to keep in mind though:

    - The EMIF does not control the "Write Protect" pin on the NAND flash. This must be controlled using a general-purpose I/O pin and managed by software.
    - The EMIF does not support NAND flashes that require the chip sleect to stay low during the data transfer time (tR).

    We don't have a ready example for you for interfacing a NAND flash memory using the EMIF on LC4357. The part number for the NAND flash memory you referred to has been EOL'ed and no documentation is readily available.

    Regards,

  • Hi Sunil,

    Thank you for your commentary.

    That means I can not drive the nanf flash K9WAG08U1B-PIB0 by TMS570LC4357.And do you mean TMS570LC4357 has been EOL'ed? But the page display it is preview.

    I also need todrive a SRAM IDT70T3539M.I use the SDRAM to test it,but I failed.Are there other points to note except the"CS0" pin?

    Regards,

  • I meant that the NAND flash part number is EOL'ed. The 570 is still in Preview, as indicated.

    How is the SDRAM connected? Can you provide a connection diagram as well as your software that configures the EMIF?

    Regards, Sunil

  • Got it.

    Thank you!

    The attached one is the connection diagram and the code is the example.

    In addition, I would like to ask how to enable the PLL1.I configured the parameters in HALCOGEN,but Idid not find changes.

  • I took a look at the IDT70T3539M datasheet. It is not a SDRAM and TMS570LC4357 EMIF does not support this type of memory.

    Thanks and regards,
