XM20C128S

The XM20C128S is a high speed nonvolatile RAM module.It is comprised of eight Xicor X20C16 high speed NOVRAMs,a high speed "ACT" decoder and decoupling capacitors mounted on a FR-4 substrate.The XM20C128S is configured 16K * 8 and is fully decoded.The moudle is a 36-pin SIP conforming to the industry standard pinout for SRAMS.The XM20C128S fully supports the AUTOSTORE feature,providing hands-off automatic storing of RAM data into E2PROM hands-off automatic string of RAM data into E2PROM when VCC falls below the AUTOSTORE theshold.The XM20C128S is a highly reliable memory component,supporting unlimited writes to RAM,a minimum 1,000,000 store cycles and a minimum 100 year data retention.

The XM20C128S has some absolute maximum ratings.When parameter is temperature under bias,the rating is -65 to +125.When parameter is storage temperature ,the rating is -65 to +125.When parameter is voltage on any pin with respect to ground,the rating is -1.0V to +7V.

Stresses above those listed under "absolute maximum ratings" may cause permanent damage to the XM20C128S.This is a stress rating only and the functional operation of the module at these or any other conditions above those indicated in the operational sections of this specification is not implied.Exposure to absolute maximum rating conditions for extended periods may affect module reliability.
