Product Overview

The DS1314S+ is a 3V non-volatile controller with lithium battery monitor in 16 pin WSOIC 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
