3V Nonvolatile Controller with Lithium Battery Monitor

DS1314S-2+ DESCRIPTION

The DS1314S-2+ DS1314 Nonvolatile Controller with Battery Monitor is a CMOS circuit which solves the application problem of converting CMOS RAM into nonvolatile memory. Incoming power is monitored for an outof-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.

DS1314S-2+ FEATURES

 Converts CMOS SRAM into nonvolatile memory

 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 3.0V or 3.3V power supplies

 Space-saving 8-pin DIP and SOIC packages

 Optional 16-pin SOIC and 20-pin TSSOP versions reset processor when power failure occurs and hold processor in reset during system power-up

 Industrial temperature range of -40°C to +85°C
