ADC Converter
The ME310G1 is provided by one AD converter. It is able to read a voltage level in the range
of 0÷1.8 volts applied on the ADC pin input, store and convert it into 10 bit word.
The input lines are named as ADC (available on Pad B18).
The following table is showing the ADC characteristics:

Refer to SW User Guide or AT Commands Reference Guide for the full description of this
function.
DAC Converter
The ME310G1 provides a Digital to Analog Converter. The signal (named DAC) is available
on pin R16 of the ME310G1.

CTANK
The ME310G1 provides an internal supply domain pin for additional capacitance or pullup
reference to support only the specific use cases described in ME310G1 documentation.
The internal supply domain (named CTANK) is available on pin N4 of the ME310G1.
User application circuit should add a place-holder capacitor of 100uF 4V connected to pin
N4 of the ME310G1 to support an enhanced power loss recovering.
Forced USB boot
In some case of firmware upgrade FORCED_USB_BOOT pin must be set to 1.8V during
poweron of ME310G1.
The input current is very low so 10K resistor to CTANK (pin N4) can be used to keep this
pin in HI state.
FORCED_USB_BOOT pin must be connected only during firmware upgrade operation and
normally it has to be left open.
