3.20.2
SCF5250 includes an on-chip crystal oscillator. The crystal should be connected between CRIN and
CROUT. An externally generated clock signal can also be used and should be connected directly to the
CRIN pin.
3.21
To exit power down mode, apply a LOW level to the WAKE_UP/GPIO21 input pin.
3.22
The SCF5250 includes an on-chip linear regulator. This regulator provides an 1.2 V output which is
intended to be used to power the SCF5250 core. Three pins are associated with this function.
LININ, LINOUT and LINGND. Typically LININ would be fed by the I/O (PAD) supply (3.3 V) with
separate filtering recommended to provide some isolation between the I/O and the core.
In portable solutions this linear regulator may not be efficient enough and in this case we would expect the
1.2 V supply to be generated externally, possibly by a highly efficient DC-DC convertor.
If not used leave pins not connected.
