DESCRIPTION  
The DS1210 Nonvolatile Controller Chip is a CMOS circuit which solves the application problem of  
converting CMOS RAM into nonvolatile 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.  
The 8-pin DIP package keeps PC board real estate requirements to a minimum. By combining the  
DS1210 Nonvolatile Controller Chip with a CMOS memory and batteries, nonvolatile RAM operation  
can be achieved.
