MXD1210CPA+

MXD1210CPA+ non-volatile RAM controller is a very low power CMOS circuit that converts standard (volatile) CMOS RAM into non-volatile 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. Typical applications includes microprocessor systems, computers, embedded systems.

• 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
• 4.75V to 5.50V supply voltage at TOL = GND, 0.23mA typical supply current at VBATT1 = VBATT2 = 3V
• 0°C to +70°C temperature range, 8 PDIP package
