The MK48T08B-15 is a highly integrated Timekeeper® SRAM from STMicroelectronics, designed to provide a full-featured battery-backed clock and non-volatile memory solution for sophisticated electronic systems. This integrated circuit combines 8K x 8 bits of static RAM with a built-in real-time clock/calendar (RTC) and a power-fail control circuit, all in a single monolithic chip.

Key Features

• Memory Storage: 8Kb (8K x 8) of NV SRAM allows for quick and easy access to data with unlimited read/write cycles.
• Real-Time Clock: The integrated RTC tracks time in hours, minutes, and seconds, and the date in terms of day, month, year, and century with leap year compensation up to the year 2100.
• Battery Backup: An onboard battery input allows for data retention and clock operation when the primary power is lost, ensuring continuous timekeeping and data preservation.
• Power-fail DeSelect (PFD): The PFD feature automatically switches to the battery supply during a power failure, maintaining data and clock operations without interruption.
• Access Time: The device has a fast access time of 150 ns, allowing for swift data retrieval and storage.
• Package: Housed in a 28-pin, 600 mil DIP CAPHAT™ package, the MK48T08B-15 is designed for easy integration into a wide range of applications.
