Description
Monitor 2
Monitoring internal signals (digital), use
for system control
At no use, open this pin.
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:
Input
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.
Monitor 4
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.
Supply Voltage Selector
Select supply voltage. Connect power
supply for 5V use. / Ground for 3V use.
Notice:
Input
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
between the pin and the voltage source.
