Overview
The M48Z12-70PC1 is a non-volatile static RAM (SRAM) produced by STMicroelectronics. It is part of the M48Z02/12 ZEROPOWER® RAM series, which is pin and function compatible with the DS1220. This device is housed in a special 24-pin, 600 mil DIP CAPHAT™ package that includes a long-life lithium button cell, providing a highly integrated battery-backed memory solution. The battery has sufficient capacity to maintain data functionality for at least 10 years in the absence of power over the commercial operating temperature range.
