The M48T35Y-70PC1 is a 32kb x 8 TIMEKEEPER? Non-volatile Static RAM and Real-time Clock. The monolithic chip is to provide a highly integrated battery-backed memory and real-time clock solution. The RAM is a non-volatile pin and function equivalent to any JEDEC standard 32kb x 8 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 write that can be performed. The 28-pin, 330mil SOIC provides sockets with gold plated contacts at both ends for direct connection to a separate SNAPHAT? housing containing the battery and crystal.
