AM335x Synchronous NAND

Other Parts Discussed in Thread: AM3352, AM3517

I have a customer asking of the AM3352 supports Synchronous NAND (Micron G08ABCBBH1-12IT:B). 

I checked the forum postings and found the AM3517 does not.  I assume it is the same for the AM335x.  Additionally, I found in the AM335x TRM the following statements:

7.1.3.3.8.2.1 Supported Devices

The access protocol of each chip-select can be independently specified through the GPMC_CONFIG1_i[11-10] DEVICETYPE parameter for:

• Random-access synchronous or asynchronous memory like NOR flash, SRAM

• NAND flash asynchronous devices

For more information about the NAND flash GPMC basic programming model and NAND support, see Section 7.1.3.3.12 and Section 7.1.3.3.12.1.

I think the answer is "no" it does not support synchronous NAND, but I would like for you to confirm this.

    Hi Ignacio,

    If the part number is MT29F16G08ABCBBH1-12IT:B, then this NAND is asynchronous/synchronous. It supports both modes and is ONFI-compliant, so should work with the AM335X. Otherwise yes, AM335X does not support synchronous NAND devices.

    Please note that the Micron product page states that this device is "EOL pending".
