Product Summary
The M48T08-150PCI is a 8K x 8 non-volatile static RAM and real time clock which is pin and functional compatible with the DS1643. The monolithic chip is available in two special packages to provide a highly integrated battery backed-up memory and real time clock solution. The M48T08-150PCI is a non-volatile pin and function equivalent to any JEDEC standard 8K x 8 SRAM. The M48T08-150PCI is also easily fits into many ROM, EPROM, and EEPROM sockets, providing the non-volatility of PROMs without any requirement for specia WRITE timing or limitations on the number of WRITEs that can be performed.
