AM4376: Parallel NOR Flash

Kanae

Part Number: AM4376

Hi Support Team,

I have a question from my customer who is checking the information on the following website posted about QSPI restrictions.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/984389/am4376-support-of-256mb-qspi-flash/3643133

Q. If I use Parallel NOR Flash Memory instead of Serial NOR Flash Memory with GPMC connection,
am I right in understanding that I can read and write to the entire 256Mbyte area?
(Because "Support 512M Bytes maximum addressing capability~" is mentioned in "9.1.1.1 GPMC Features" of TRM.)

I think it can be used without any problem, but please let me check just to be sure.

As for Parallel NOR Flash, we are considering Micron's MT28FW02GBBA1HPC-0AAT.

Kanae

Hi Sreenivasa,

Thank you for your reply.
I understand that there is no limitation as to the size, as stated in the TRM that 512MB is supported.
I will inform my customer to design according to the above TRM item.

Best Regards,
Kanae
