DS1210 - Nonvolatile Controller

DS1210 Description

19-6294; Rev 6/12 DS1210 Nonvolatile Controller Chip .
VCCO - RAM Supply VBAT1 - + Battery 1 TOL - Power Supply Tolerance GND - Ground CE - Chip Enable Input CEO VBAT2 VCCI NC - Chip Enable Outp.

DS1210 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

DS1210 Applications

* data integrity is paramount. In these applications it is often desirable to use two batteries to ensure reliability. The DS1210 controller provides an internal isolation switch which allows the connection of two batteries. During battery backup operation the battery with the highest voltage is sele
