CCS/OMAPL137-HT: is ONFI supported

Alejandro Zepeda
Prodigy 10 points
Part Number: OMAPL137-HT
Other Parts Discussed in Thread: OMAP-L137,

Tool/software: Code Composer Studio

Hello.

In the datasheet for the OMAP-L137 figure 6-12 it clearly shows a flash connected to the processor's EMIFA using the open NAND flash interface (ONFI).

I am using the high-temperature version of this processor: OMAPL137-HT. Nowhere in the OMAPL137-HT datasheet is there any mention on ONFI support.

My question is: does the OMAPL137-HT also support ONFI?

And more generally, if I see something is supported by the OMAP-L137 is it safe to assume it is also supported by the OMAPL137-HT?

Thanks in advance,

Alejandro

    Hi,

    Both devices share the same TRM:
    www.ti.com/.../technicaldocuments
    The TRM itself is:
    www.ti.com/.../spruh92d.pdf

    So yes, regarding functionality, it should be the same. Regarding hardware parameters like electrical characteristics, timings, thermal characteristics, refer to the device specific Data Manual.

    My question is: does the OMAPL137-HT also support ONFI?

    Yes, it should support ONFI.

    Best Regards,
    Yordan

    Yes, this device has a EMIFA controller to interface with parallel NAND which supports all devices that are compatible with ONFI 1.0 standard. For additional information we provide NAND devices that have previously been used by customer/TI evaluation platforms:


    All technical peripheral and regsiter related documentation that is supported by OMAPL137 also applies to OMAPL137-HT.
    processors.wiki.ti.com/.../List_of_NANDs_devices_supported_by_TI_RBLs

    Alll device listed there have the same EMIFA peripheral so you can pick any one of the devices listed there. We recommend that before placing production orders for NAND parts that you evaluate this on smaller set of your custom hardware.

    Hope this helps.
