DS1210+

The DS1210+ is a non-volatile Controller Chip features unconditionally write protects when VCC is out-of-tolerance. The 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.

• Converts CMOS RAMs into non-volatile memories
• Automatically switches to battery when power-fail occurs
• Consumes <lt/>100nA of battery current
• Tests battery condition on power up
• Provides for redundant batteries
• Low forward voltage drop on the VCC switch
