Overview
The M48Z12-200PC1 is a 5 V, 16 Kbit (2 K x 8) ZEROPOWER® SRAM produced by STMicroelectronics. This non-volatile static RAM is pin and function compatible with the DS1220 and is housed in a special 24-pin, 600 mil DIP CAPHAT™ package. The package includes a long-life lithium button cell, providing a highly integrated battery-backed memory solution. This component maintains data functionality for at least 10 years in the absence of power over the commercial operating temperature range.
