... Rev 1; 3/96 _______________General Description The MXD1210 nonvolatile RAM controller is a very low- power CMOS circuit that converts standard (volatile) CMOS RAM into nonvolatile memory. It also continually monitors the power supply to provide RAM write protec- tion when power to the RAM marginal (out-of- tolerance) condition ...
