ADC Interface*
UC200T-EM module provides two analog-to-digital converters (ADC). In order to improve the accuracy of
ADC, the trace of ADC should be surrounded by ground.
Table 16: Pin Definition of the ADC Interface
The following table describes the characteristic of the ADC function.
Table 17: Characteristic of the ADC
1.
“*” means under development.
2.
It is prohibited to supply any voltage to ADC pins when VBAT is removed.
3.
It is recommended to use resistor divider circuit for ADC application.

Network Status Indication
The network indication pins can be used to drive network status indication LEDs. The module provides
two pins which are NET_MODE and NET_STATUS. The following tables describe pin definition and logic
level changes in different network status.
