DS1314 Datasheet 3v Nonvolatile Controller

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-6307; Rev 6/12 DS1314 3V Nonvolatile Controller with Lithium Battery.

General Description

VCCI VCCO VBAT - Power Supply Input - SRAM Power Supply Output - Backup Battery Input CEI - Chip Enable Input CEO TOL BW - Chip Enable Output - VCC Tolerance Select - Battery Warning Output (Open Drain) RST GND NC - Reset Output (Open Drain) - Ground - No Connection DESCRIPTION The 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.

Key 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 packa.
