Using ADC Converter
Available in a next document revision.
DAC Converter
The ME310G1 provides a Digital to Analog Converter. The signal (named DAC) is available
on pin R16 of the ME310G1.
Enabling DAC

CTANK
The ME310G1 provides an internal supply domain pin for additional capacitance or pullup
reference to support only the specific use cases described in the ME310G1
documentation. The internal supply domain (named CTANK) is available on pin N4 of the
ME310G1.
The user’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 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 the firmware upgrade operation
and normally must be left open.
FORCED_USB_BOOT and CTANK pins must be available in the user application circuit
throught the test points for easy connection of 10K resistor.
