Product Overview

The DS1312S+ is a non-volatile controller with lithium battery monitor in 16 pin WSOIC package. This non-volatile controller with battery monitor is a CMOS circuit which solves 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. In addition to battery backup support device performs important function of monitoring remaining capacity of lithium battery and providing a warning before battery reaches end of life.
  • Supply voltage range is 4.5V to 5.5V, voltage tolerance of 10%
  • Operating temperature range from -40°C to 85°C
  • Converts CMOS SRAM into non-volatile 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
  • Space saving package
  • Resets processor when power failure occurs, hold processor in reset during system power-up
