M48T18-100PC1 ST TIMEKEEPER® SRAM | 28-PCDIP, CAPHAT® | 64Kb, 100ns

Product Overview

The STMicroelectronics M48T18-100PC1 is a 64Kb (8Kb x 8) TIMEKEEPER® SRAM with an integrated battery and quartz crystal in a CAPHAT® package. It combines a low-power SRAM with a real-time clock (RTC) and a power-fail control circuit, ensuring data retention and timekeeping for over 10 years in the absence of external power. The device operates from a single 4.5V to 5.5V supply and features a 100ns access time. The 28-pin PCDIP package with CAPHAT® provides a compact, reliable solution for non-volatile memory and timekeeping in industrial and telecommunications applications.
