DET_TMONI3
Analog
Output
Monitor 3
Monitoring internal signals (Converted to
analog / in User Test )
At no use, open this pin.
Notice:
In User Test, Supply at least 3 V to
COM_VDD pin to monitor the signal.
Lower voltage supply causes an incorrect
monitoring.

Enable Pin
Select to enable (In SPI Mode)
Address Setting (In EEPROM Mode)
Set a start address to read memory data.
Notice:
Do not supply higher voltage than the
level of COM_VDD. (For example, in the
case of too low / no power supply.) That
causes overcurrent at this pin, as the
ESD protection elements insertion
between the pin and the voltage source.

Input
Supply Voltage Selector
Select supply voltage. Connect power
supply for 5V use. / Ground for 3V use.
Notice:
Do not supply higher voltage than the
level of COM_VDD. (For example, in the
case of too low / no power supply.) That
causes overcurrent at this pin, as the
ESD
