DS1210 Datasheet Nonvolatile Controller

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-6294; Rev 6/12 DS1210 Nonvolatile Controller Chip.

General Description

VCCO - RAM Supply VBAT1 - + Battery 1 TOL - Power Supply Tolerance GND - Ground CE - Chip Enable Input CEO VBAT2 VCCI NC - Chip Enable Output - + Battery 2 - + Supply - No Connect DESCRIPTION The DS1210 Nonvolatile Controller Chip is a CMOS circuit which solves the application problem of converting CMOS RAM into nonvolatile 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.

Key Features

  • Converts CMOS RAMs into Nonvolatile Memories.
  • Unconditionally Write Protects when VCC is Out-of-Tolerance.
  • Automatically Switches to Battery when Power-Fail Occurs.
  • Space-Saving 8-Pin PDIP or 16-Pin SO Packages.
  • Consumes.
