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 is in a marginal (out-of-tol-
erance) condition. When the power supply begins to
fail, the RAM is write-protected, and the device switch-
es to battery-backup mode.
