Pin Descriptions
SPI chip select bar input pin. In the SPI communication mode, this pin functions as the slave select input. In the I
communication mode, this pin is not used and should be tied to V
Serial data out pin. In the SPI communication mode, this pin functions as the serial data output. In the I
mode, this pin is not used in the default configuration. It is always in the high impedance state. If Auth signaling is enabled,
then this pin functions as the AuthO output. (See Section J.5)
No connect pin. This package pin is not used and can be left open by the user.
Ground
Serial data in pin. In SPI communication mode this pin functions as the serial data input. In I
functions as the serial data I/O.
Serial clock input pin. In both SPI and I
No connect pin. This package pin is not used and can be left open by the user.
