XRA1200/1200P
8-BIT I2C/SMBUS GPIO EXPANDER
SEPTEMBER 2011
REV. 1.0.0
GENERAL DESCRIPTION
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 XRA1200/1200P 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 XRA1200P is pin and
software
compatible
with
the
CAT9554
and
PCA9554.
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.
