Product Summary

The M48T35Y-70PC1 is a 32Kb x8 non-volatile static RAM and real time clock. The monolithic chip is available in two special packages to provide a highly integrated battery backed-up memory and real time clock solution. The M48T35Y-70PC1 is a non-volatile pin and function equivalent to any JEDEC standard 32Kb x8 SRAM. The M48T35Y-70PC1 is 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.
