GENERAL DESCRIPTION
The XRA1201/1201P is a 16-bit GPIO expander with
an I
XRA1201 has internal 100K ohm pull-up resistors on
each I/O pin that can be individually enabled. The
XRA1201P has 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 XRA1201/1201P 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 XRA1201/1201P are enhanced versions of other
16-bit GPIO expanders with an I
The XRA1201 is pin and software compatible with the
PCA9535, TCA9535 and MAX7312. The XRA1201P
is pin and software compatible with the CAT9555,
PCA9555, TCA9555, MAX7311 and MAX7318.
The XRA1201/1201P are available in 24-pin QFN
and 24-pin TSSOP packages.
