DS1244/DS1244P
7 of 19
BATTERY LONGEVITY
The DS1244 has a lithium power source that is designed to provide energy for clock activity and clock
and RAM data retention when the V
CC
supply is not present. The capability of this internal power supply
is sufficient to power the DS1244 continuously for the life of the equipment in which it is installed. For
specification purposes, the life expectancy is 10 years at +25 C with the internal clock oscillator running
in the absence of V
CC
power. Each DS1244 is shipped from Dallas Semiconductor with its lithium energy
source disconnected, guaranteeing full energy capacity. When V
CC
is first applied at a level greater than
V
PF
, the lithium energy source is enabled for battery-backup operation. Actual life expectancy of the
DS1244 will be much longer than 10 years since no lithium battery energy is consumed when V
CC
is
present.
