M48T35Y-70PC1

Fabricant : STMicroelectronics

Description :
The M48T35/Y TIMEKEEPER®RAM is a 32 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 memory and real-time clock solution.The M48T35/Y is a non-volatile pin and function equivalent to any JEDEC standard 32 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. The 28-pin, 600 mil DIP CAPHAT™houses the M48T35/Y silicon with a quartz crystal and a long life lithium button cell in a single package. FEATURES Integrated, ultra low power SRAM, real-time clock, and power-fail control circuit BCD coded year, month, day, date, hours, minutes, and seconds More than 4 million Write cycles More than 200-years data retention Self-contained battery and crystal in the CAPHAT™DIP package
