Overview
The M48Z02-150PC1 is a non-volatile static RAM (SRAM) produced by STMicroelectronics. This component is part of the ZEROPOWER® RAM series, which integrates ultra-low power SRAM and power-fail control circuitry. It is pin and function compatible with the DS1220 and JEDEC standard 2 K x 8 SRAMs. The M48Z02-150PC1 features 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. This design ensures data functionality for at least 10 years in the absence of power over the commercial operating temperature range.
