DESCRIPTION
The PCA9539 is a 24-pin CMOS device that provide 16 bits of
General Purpose parallel Input/Output (GPIO) expansion with
interrupt and reset for I
to enhance the Philips family of I
provides a simple solution when additional I/O is needed for ACPI
power switches, sensors, pushbuttons, LEDs, fans, etc.
The PCA9539 consists of two 8-bit Configuration (Input or Output
selection); Input, Output and Polarity inversion (Active HIGH or
Active LOW operation) registers. The system master can enable the
I/Os as either inputs or outputs by writing to the I/O configuration
bits. The data for each Input or Output is kept in the corresponding
Input or Output register. The polarity of the read register can be
inverted with the Polarity Inversion Register. All registers can be
read by the system master.
The PCA9539 is identical to the PCA9555 except for the removal of
the internal I/O pull-up resistor which greatly reduces power
consumption when the I/Os are held LOW, repleacement of A2 with
RESET and different address range.
The PCA9539 open-drain interrupt output is activated when any
input state differs from its corresponding input port register state and
is used to indicate to the system master that an input state has
changed. The power-on reset sets the registers to their default
values and initializes the device state machine. The RESET pin
causes the same reset/sonfiguration to occur without depowering
the device.
Two hardware pins (A0, A1) vary the fixed I
to four devices to share the same I
