retain data. During power-up, when V
CC
rises above approximately 3.0V, the power switching circuit
connects external V
CC
to RAM and disconnects the lithium energy source. Normal RAM operation can
resume after V
CC
exceeds 4.75V for the DS1258AB and 4.5V for the DS1258Y.
FRESHNESS SEAL
The DS1258 devices are shipped from Dallas Semiconductor with the lithium energy sources
disconnected, guaranteeing full energy capacity. When V
CC
is first applied at a level greater than V
TP
, the
lithium energy source is enabled for battery backup operation.
