Compatible external flash chips

Hello everyone,

If possible I’d like some recommendations on some compatible flash chips to interface to our 9P 9215 modules.

I’m aware that the on-module flash was changed from 4MB Spansion to an ST Micro M29W32OEB70N6, due to obsolescence. We would like to add an external 128MB flash chip but are nervous about whether the new chip will interface seamlessly, after the changes needed form the change made above.

Can anyone help point me in a suitable direction?
