XRA1202
8-BIT I2C/SMBUS GPIO EXPANDER WITH RESET
SEPTEMBER 2011
REV. 1.0.0
GENERAL DESCRIPTION
The XRA1202 is an 8-bit GPIO expander with an I2C/
SMBus interface. After power-up, the XRA1202 has
internal 100K ohm pull-up resistors on each I/O pin
that can be individually enabled.
In addition, the GPIOs on the XRA1202 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 XRA1202 is an enhanced version of the
PCA9538. The XRA1202 is pin and software
compatible with the PCA9538 (note: software
registers are compatible to the PCA9538, but the I2C
slave address is different).
The XRA1202 is available in 16-pin QFN and 16-pin
TSSOP packages.
