OPERATION
The DS1380 performs exactly to the specifications of
the DS1381 with the exception of an external battery
connection. The V
BAT
pin is designed for a battery input
voltage between 2.7 volts and 3.5 volts and requires a
current of 100 nA at 25
°
C and 1
μ
A at 60
°
C. If battery
backup operation is not required, the V
BAT
input must be
grounded. With the external battery connected, the
DS1380 is nonvolatile and retains data in the absence of
power. When the V
BAT
input is grounded, the DS1380 is
volatile and will not retain data without V
CC
. For detailed
operation and electrical specifications consult the
DS1381 data sheet.
