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 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.

Key Features   Applications/Uses
  • Battery Backup
  • Memory Write Protection
  • 230µA Operating-Mode Quiescent Current
  • 2nA Backup-Mode Quiescent Current
  • Battery Freshness Seal
  • Optional Redundant Battery
  • Low Forward-Voltage Drop on VCC Supply Switch
  • 5% or 10% Power-Fail Detection Options
  • Tests Battery Condition During Power-Up
  • 8-Pin SO Available
