External SIM Holder
SIM circuit reference design is as follows. The minimum value of Capacitor on SIMVCC is
1uF.
ADC Converter
The NL865H2-W1 is provided by two AD converters. They are able to read a voltage level
in the range of 0÷1.4 volts applied on the ADC pin input, store and convert it into 10 bit
word. The input lines are named as
ADC_IN1
and
ADC_IN2.
The following table is showing the ADC characteristics:
