The DS1210SN+ is a non-volatile controller chip in 16 pin WSOIC package. The non-volatile controller chip is a CMOS circuit which solves the application problem of converting CMOS RAM into non-volatile memory. Incoming power is monitored for an out of tolerance condition. When such a condition is detected, chip enable is inhibited to accomplish write protection and the battery is switched on to supply the RAM with uninterrupted power. Special circuitry uses a low-leakage CMOS process which affords precise voltage detection at extremely low battery consumption. By combining the DS1210 non-volatile controller chip with a CMOS memory and batteries, non-volatile RAM operation can be achieved.

• Supply voltage range is 4.5V to 5.5V
• Operating temperature range from -40°C to 85°C
• Unconditionally write protects RAM when VCC is out of tolerance
• Automatically switches to battery backup supply when VCC power failure occurs
• Tests battery condition on power up
• Provides for redundant batteries
• Low forward voltage drop on the VCC switch
• Consumes less than 100nA of battery current
