STM32 external SRAM memory compatibility

[FlorentNapoleoni]

Hello,

As part of a board re-design due to obsolescence,I need to find a replacement for the existing microprocessor and my choice is the STM32F429.

Because of its 32-bit flexible memory controller (FMC). I wanted to know if there is a document specifying which memory references are compatible with the STM32F429 memory controller.

If not, I wanted to know whether the following reference might be compatible with the FMC : CY7C1041G30-10ZSXI

My question concerns SRAM memory read/write times.

Thank you for your help.

 

Best Regards,

CY7C1041G30-10ZSXI size is 4 Mbit = 512 KBytes.

While waiting for useful replies, have you considered other STM32 models that have more than 512KB *internal* SRAM? Save on the SRAM chip, board space and lot of pins for the FMC.
