Maxim Integrated MXD1210
The MXD1210 nonvolatile RAM controller is a very lowpower CMOS circuit that converts standard (volatile) CMOS RAM into nonvolatile memory. It also continually monitors the power supply to provide RAM write protection when power to the RAM is in a marginal (out-of-tolerance) condition. When the power supply begins to fail, the RAM is write-protected, and the device switches to battery-backup mode.| Part No. | MXD1210 |
