2v5 Epcs

We have been using the ST Micro M25P16 as EPCS device for 3V3 designs. Is there a 2V5 equivalent flash chip or alternative? Thanks. The only relevant info I have found is Altera AN 523: Cyclo...

Apparently, there's no market for 2.5 V serial flash devices, otherwise the leading manufacturers surely would service it. So if you want to operate an FPGA with 2.5V VCCIO only, you have to provide an additional non-standard 2.7 - 3.0 V serial flash supply. I guess, that future serial flash will be rather using 1.8V, like some Atmel AT25DFxx types.
