1. General description
The PCA9539A is a low-voltage 16-bit General Purpose Input/Output (GPIO) expander
with interrupt and reset for I
simple solution when additional I/Os are needed while keeping interconnections to a
minimum, for example, in ACPI power switches, sensors, push buttons, LEDs, fan control,
etc.
In addition to providing a flexible set of GPIOs, the wide V
allows the PCA9539A to interface with next-generation microprocessors and
microcontrollers where supply levels are dropping down to conserve power.
The PCA9539A contains the PCA9539 register set of four pairs of 8-bit Configuration,
Input, Output, and Polarity Inversion registers.
The PCA9539A is a pin-to-pin replacement to the PCA9539, and other industry-standard
part numbers. A more fully featured part, PCAL9539A is also available with Agile I/O
features. See the respective data sheet for more details.
The PCA9539A open-drain interrupt (INT) 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.
INT can be connected to the interrupt input of a microcontroller. By sending an interrupt
signal on this line, the remote I/O can inform the microcontroller if there is incoming data
on its ports without having to communicate via the I
remain a simple slave device.
The device outputs have 25 mA sink capabilities for directly driving LEDs while consuming
low device current.
The power-on reset sets the registers to their default values and initializes the device state
machine. In the PCA9539A, the RESET pin causes the same reset/default I/O input
configuration to occur without de-powering the device, holding the registers and I
state machine in their default state until the RESET input is once again HIGH. This input
requires a pull-up to V
Two hardware pins (A0, A1) select the fixed I
to share the same I
