Table 33 ADC Characteristics
5.10.1
Using ADC Converter
Available in the next document revision.
5.11
DAC Converter
The Telit ME310G1 module includes a Digital Analog Converter. The signal (named DAC)
is available on pin R16 of the module.
5.11.1
Enabling DAC
Available in a next document revision.
5.12
CTANK
The Telit ME310G1 module includes an internal supply domain pin for additional
capacitance or pull up reference. It supports only the specific use cases described in the
Telit ME310G1 module documentation. The internal supply domain (named CTANK) is
available on pin N4 of the ME310G1.
The use
r’s
application circuit should add a place-holder capacitor of 100uF 4V connected
to pin N4 of the ME310G1 to support an enhanced power loss recovery.
5.13
Forced USB Boot
In some cases of firmware upgrade, the FORCED_USB_BOOT pin must be set to 1.8V
when power-on of the module.
The input current is very low, so 10K resistor to CTANK (pin N4) may be used to keep this
pin in the HI state.
FORCED_USB_BOOT pin must be connected only during the firmware upgrade operation.
It must be left open during normal operation.
FORCED_USB_BOOT and CTANK pins must be available in the user application circuit at
all test points for easy connection of the 10K resistor.
