DS1314S-2+T&R

The DS1314S-2+T&R is a 3V non-volatile controller with lithium battery monitor in 8 pin NSOIC package. The non-volatile controller with battery monitor 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.

• Supply voltage range is 2.7V to 3.6V
• Operating temperature range from -40°C to 85°C
• Unconditionally write protects SRAM when VCC is out of tolerance
• Automatically switches to battery backup supply when VCC power failure occurs
• Monitors voltage of a lithium cell and provides advanced warning of impending battery failure
• Signals low battery condition on active low battery warning output signal
• Automatic VCC power-fail detection for 3V or 3.3V power supplies
