DS1212 Overview
Drawings Section DESCRIPTION The DS1212 Nonvolatile Controller x16 Chip is a CMOS circuit that solves the application problem of converting CMOS RAMs into nonvolatile memories. Ining power is monitored for an out-oftolerance condition. When such a condition is detected, the chip enables are inhibited to acplish write protection and the battery is switched on to supply the RAMs with uninterrupted power.
