SRAM....Volatile or Non-Volatile
« on: April 25, 2017, 03:22:49 pm »
Is there a way to find out from the part number whether a SRAM component is volatile or non-volatile? In particular, a Cypress component.

Thanks for any help.

SRAM is volatile unless there is a battery attached to supply power 100% of the time.  That part has no built-in battery so you'd have to look at the rest of the board.

Cypress makes some nonvolatile SRAM which does not require a battery or external power but the CY62137 is just a normal low standby power SRAM.
