DLPC350: Compatibility with external parallel flash memory

Hi,

I am asking this question on behalf of another engineer so I hope I don't forget any information.

We have used the DLPLCR4500EVM as our reference design, but with the NOR memory being scarce, we have decided to change the external parallel flash memory.

In the DLPC350 datasheet:

The DLPC350 controller provides two external program memory chip selects:

• PM_CS_1 is mandatory CS for boot flash device (Standard NOR Flash ≤ 128 Mb).
• PM_CS_2 is available for an optional flash device (≤128 Mb).

The flash access timing is fixed at 100.5 ns for read timing, and 154.1 ns for write timing. In standby mode, these values change to 803.5 ns for read timing and 1232.1 ns for write timing.

Here is are our questions:

1. Can we use any NOR flash as long as the access times are respected? (100.5ns for read and 154.1ns for write)
2. Does the external flash page size matter?

Regards
