BU9929FV
ROHM’s GPIO is a general-purpose IO that contains I²C BUS interface. It also contains monitoring function that conveys
a change of the signal level in terminal to the host system via interrupt terminal or I²C BUS.
!Applications
Notebook PC, PC, VCR, TV etc. and other systems with I²C BUS.
!Features
1) I²C BUS interface
2) General purpose I/O port 16bits
3) State monitoring function to monitor all terminals
4) State detection signal serial output by I²C BUS master function
5) Output port of state detection signal
6) State detection ON/OFF setting input port during the default status
7) 32.768kHz clock input
8) Power supply voltage 3.3V / 5.0V
