I am currently updating an old design that uses a obsolete Numonyx (Micron) PF48F3000P0ZBQ0 128Mb NOR flash memory.  Is there an active Cypress part that would be a suitable replacement for this obsolete part?

Hi,

Thank you for contacting Cypress Community.

The suggested replacement for PF48F3000P0ZBQ0 is S29WS128P0PBFW000.

The pin out and command sets are different. This Micron device is a dual die stack. Cypress does not offer 3V VIO for 1.8V Vcc devices.

Thanks and Regards,

Apurva
