... M48Z35, M48Z35Y 1 Description The M48Z35/Y ZEROPOWER power-fail deselect circuitry and battery control logic on a single die. The monolithic chip is available in two special packages to provide a highly integrated battery-backed memory solution. The M48Z35 non-volatile pin and function equivalent to any JEDEC standard SRAM. It also easily fits into many ROM, EPROM, and EEPROM sockets, providing the non-volatility of PROMs without any requirement for special WRITE timing or limitations on the number of WRITEs that can be performed ...
