M48T02-150PC1 Real-Time Clock (RTC) ICs by STMicroelectronics

5.0 V, 16 Kbit (2 Kb x 8) TIMEKEEPER® SRAM


The M48T02/12 TIMEKEEPER ® RAM is a 2 Kb x 8 non-volatile static RAM and real-time clock which is pin and functional compatible with the DS1642. A special 24-pin, 600 mil DIP CAPHAT ™ package houses the M48T02/12 silicon with a quartz crystal and a long life lithium button cell to form a highly integrated battery-backed memory and real-time clock solution. The M48T02/12 button cell has sufficient capacity and storage life to maintain data and clock functionality for an accumulated time period of at least 10 years in the absence of power over the operating temperature range. The M48T02/12 is a non-volatile pin and function equivalent to any JEDEC standard 2 Kb 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 WRITEs that can be performed.
