XRA1200P

8-Bit I²C/SMBus GPIO Expander

Description

The XRA1200P is an 8-bit GPIO expander with an I²C/SMBus interface. 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 XRA1200P 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 XRA1200P are enhanced versions of other 8-bit GPIO expanders with an I2C/SMBus interface. The XRA1200P is pin and software compatible with the CAT9554 and PCA9554. The XRA1200P are also pin compatible with the PCA9554A and TCA9554A.

The XRA1200P are available in 16-pin QFN and 16-pin TSSOP packages.
