FEATURES
Converts CMOS RAMs into nonvolatile
memories
Automatically selects +3.0V or +5.0V
operation
SOIC version is pin-compatible with the
Dallas Semiconductor DS1210S and
DS1610S NV Controllers
Unconditionally write protects all of memory
when VCC is out of tolerance
Write protects selected blocks of memory
regardless of VCC status when programmed
Automatically switches to battery backup
supply when power-fail occurs
Provides for multiple batteries
Consumes less than 100 nA of battery current
Test battery on power-up by inhibiting the
second memory cycle
Optional 5% or 10% power-fail detection
16-pin DIP or 16-pin SOIC surface mount
package or 20-pin TSSOP package
Low forward voltage drop on the VCC switch
with currents of up to 150 mA
Optional industrial temperature range of
-40°C to +85°C
