XRA1404
8-BIT SPI GPIO EXPANDER WITH INTEGRATED LEVEL SHIFTERS
SEPTEMBER 2011
REV. 1.0.0
GENERAL DESCRIPTION
The XRA1404 is an 8-bit GPIO expander with an SPI
interface. After power-up, the XRA1404 has internal
100K ohm pull-up resistors on each I/O pin that can
be individually enabled.
In addition, the GPIOs on the XRA1404 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 XRA1404 is available in 16-pin QFN and 16-pin
TSSOP packages.
