XRA1201P - 16-BIT I2C / SMBUS GPIO EXPANDER
The XRA1201/1201P is a 16-bit GPIO expander with an I2C/SMBus interface.
After power-up, the XRA1201 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled.
The XRA1201P has the internal pull-up resistors enabled upon power-up in case it is necessary for the inputs
