-
-
-
-
maximum value is determined by the voltage
drop on PSW_N caused by leakage into
PSW_N and the external supply control pin
-
-
used to avoid floating input on the XTAL1 pin
C
C
used to AC couple the input square wave to
the XTAL1 pin
STPS0520Z; Schottky rectifier
Remark: Adding Schottky diode will bring
down the V
depending on the load current. However, it is
still within the requirement of Universal Serial
Bus Specification Rev. 2.0.
