DESCRIPTION

The DS1211 Nonvolatile Controller x 8 Chip is a CMOS circuit which solves the application problem of

converting CMOS RAMs into nonvolatile memories. Incoming power is monitored for an out-of-

tolerance condition. When such a condition is detected, the chip enables are inhibited to accomplish write

protection and the battery is switched on to supply RAMs with uninterrupted power. Special circuitry

uses a low-leakage CMOS process which affords precise voltage detection at extremely low battery

consumption.

By combining the DS1211 nonvolatile controller/decoder chip and lithium batteries, nonvolatile RAM

operation can be achieved for up to eight CMOS memories.

See the data sheet for the DS1212 Nonvolatile Controller x 16 Chip for electrical specifications and

operation.
