Product Summary
The M48T59Y-70MH1 is an 8 Kb x 8 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 M48T59Y-70MH1 is a non-volatile pin and function equivalent to any JEDEC standard 8 Kb x8 SRAM. The M48T59Y-70MH1 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.
