The XRA1200/1200P is an 8-bit GPIO expander with an I²C/SMBus interface. After power-up, the XRA1200 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled. The XRA1200P have 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 XRA1200/1200P 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 connected to the GPIO expander.

As inputs, the internal pull-up resistors can be enabled or disabled and the input polarity can be inverted. The interrupt can be programmed for different behaviors. The interrupts can be programmed to generate an interrupt on the rising edge, falling edge or on both edges. The interrupt can be cleared if the input changes back to its original state or by reading the current state of the inputs.

The XRA1200 are enhanced versions of other 8-bit GPIO expanders with an I²C/SMBus interface. The XRA1200 is pin and software compatible with the CAT9534 and PCA9534. The XRA1200/1200P are also pin compatible with the PCA9554A and TCA9554A.

The XRA1200/1200P are available in 16-pin QFN and 16-pin TSSOP packages.
