SPI Mode
I
SPI I/F Chip Select N Pin
During power-down state or when μP I/F are not in use, leave this pin “H”
level.
I²C Mode
I I²C I/F Chip Address N Pin
This pin must be pulled up or pulled down.
O
Serial Data Output Pin for SPI I/F
This pin outputs “Hi-Z” during power-down state.
I/O
Serial Data In/Output Pin for I²C I/F
This pin outputs “Hi-Z” during power-down state.
I Serial Data Clock Input Pin for SPI I/F
I Serial Data Clock Input Pin for I²C I/F
I Serial Data Input Pin for SPI I/F
I²C I/F Mode Select Input Pin
I
I2CFIL = “L”: Fast Mode (400kHz)
I2CFIL = “H”: Fast Mode Plus (1MHz) (should be fixed to TVDD2)
Power-down N Pin
I Use this pin to power down the AK7738.
The PDN pin should be held “L” when power is supplied.
LDO Output Pin
O Connect a 2.2uF ceramic capacitor between this pin and DVSS3.
Do not connect this pin to an external circuit.
- Digital Core Power Supply Pin 3.0~3.6V (typ.3.3V)
- Digital Ground 3 Pin 0V (Substrate potential)
