AWR1243: Alternate Flash Chip?

Fabian Schwartau

Part Number: AWR1243

Hello everyone,

is there somewhere a list of campatible flash chips for the AWR1243? In the reference design an S25FL116K0XNFV010 is used but this part is obsolete (and out of stock everywhere) and I cannot find a list of compatible parts or requirements the chip needs to fulfill.

Best Regards,

Fabian

Hi Fabian,

The S25FL116K0XNFV010 is a 2 MB, SPI Flash Memory rated for 3.0 Volts. Any suitable flash memory part that meets the same specs will be appropriate.

Follow this question, is there any other SPEC requirement for the SPI flash except 3.0V?
If I don't use Cypress, but other vendor like GigaDevice's GD25Q32C. Is this flash ok?

Jesse,

This is a very good question, I'm going to get in touch with one of our experts on board design and I'll get back to you. I'll make sure you're CC'd on that email.

Cheers,
Akash

Can you please keep me in the loop?

I tried the SST26VF016B-104I/SN but it did not work - no idea why.
