GENERAL DESCRIPTION

The XRA1200/1200P is an 8-bit GPIO expander with

an I

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.

different

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 XRA1200/1200P are enhanced versions of other

8-bit GPIO expanders with an I

The XRA1200 is pin and software compatible with the

CAT9534 and PCA9534. The XRA1200P is pin and
