Function
I Serial Data Input Pin 1 (for SRC)
I Serial Data Input Pin 3
O
Data Write Ready Output Pin for Microprocessor Interface
This pin outputs RDY, and outputs “H” during initial reset.
Microprocessor Interface Write Request Pin (I2CSEL pin = “L”)
I When initial reset state and Microcomputer interface are not in use, leave
RQN pin= “H”.
I I²C Bus Address Setting Pin 1 (I2CSEL pin = “H”)
I Serial Data Clock Pin for Microprocessor Interface (I2CSEL pin = “L”)
When SCLK is not used, tie the SCLK pin = “H”.
I I²C Bus Data Clock Pin (I2CSEL pin = “H”)
I Serial Data Input Pin for Microprocessor Interface (I2CSEL pin = “L”)
When SI is not used, tie the SI pin = “L”.
I I²C Bus Address Setting Pin 0 (I2CSEL pin = “H”)
O
Serial Data Output Pin for Microprocessor Interface
Outputs “L” during initial reset.
O I2CSEL pin = “L”
Leave this pin Open. SDA outputs “L”.
I/O I²C Bus Data Clock Pin (I2CSEL pin = “H”)
Outputs “Hi-z” during initial reset.
- Digital Power Supply Pin 3.0~3.6V
- Ground Pin 0V
O
Clock Output Pin
This pin outputs “L” during initial reset.
O
