Stmicroelectronics (M48T08-100PC1) RTC, Timekeeper NVSRAM, Parallel

RTC, Timekeeper NVSRAM, Parallel, 4.75 V to 5.5 V, DIP-28

Product Overview
The M48T08-100PC1 is a 5V, 64Kbit (8Kb x 8) TIMEKEEPER non volatile static RAM and real time clock in 28 pin DIP package. This real time clock is pin and function compatible with DS1643. It provides highly integrated battery backed memory and real time clock solution. The M48T08-100PC1 is a non volatile pin and function equivalent to any JEDEC standard 8K 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 number of WRITEs that can be performed.

Integrated ultra low power SRAM, real time clock, power fail control circuit and battery
