Product Summary
The m48T08-150pc1 is an 8K x 8 non-volatile static RAM and real time clock which is pin and functional compatible with the DS1643. The m48T08-150pc1 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. The m48T08-150pc1 is available in two special packages to provide a highly integrated battery backed-up memory and real time clock solution.
