MXD1210CPA+

The MXD1210CPA+ from Maxim Integrated Products is a non-volatile RAM controller in 8 pin DIP package. This non-volatile RAM controller is a very low power CMOS circuit that converts standard (volatile) CMOS RAM into non-volatile memory. It also continuously monitors power supply to provide RAM write protection when power to the RAM is in a marginal (out of tolerance) condition. When power supply begins to fail RAM is write protected and device switches to battery backup mode. It is used in microprocessor systems, embedded systems and computers.

• Supply voltage range is 4.5V to 5.5V
• Operating temperature range from 0°C to +70°C
• Battery backup

• 230µA operating mode quiescent current
• 2nA backup mode quiescent current
• Battery freshness seal
• Optional redundant battery, tests battery condition during power-up
• Low forward voltage drop on VCC supply switch
• 5% or 10% power fail detection options
