This datasheet also covers the XRA1201 variant, as both devices belong to the same 16-bit i2c / smbus gpio expander family and are provided as variant models within a single manufacturer datasheet.
General Description
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 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 to be in a known state. In addition, the GPIOs on the XRA1201/1201P can individually be controlled and configured. As outputs, the GPIOs can be outputs that are high, low or in three-state mode. The three-state mode feature is useful for applications where the power is removed from the remote devices, but they may still be conne
