PCA9535A

Low-voltage 16-bit I²C-bus I/O port with interrupt

Rev. 1 — 11 September 2012

Product data sheet

1. General description

The PCA9535A is a low-voltage 16-bit General Purpose Input/Output (GPIO) expander

with interrupt and reset for I²C-bus/SMBus applications. NXP I/O expanders provide a

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_DDrange of 1.65 V to 5.5 V

allows the PCA9535A to interface with next-generation microprocessors and

microcontrollers where supply levels are dropping down to conserve power.

The PCA9535A contains the PCA9535 register set of four pairs of 8-bit Configuration,

Input, Output, and Polarity Inversion registers.

The PCA9535A is a pin-to-pin replacement to the PCA9535 and other industry-standard

devices. A more fully featured device, the PCAL9535A, is available with Agile I/O

features. See the respective data sheet for more details.

The PCA9535A 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 I²C-bus. Thus, the PCA9535A can

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.

Three hardware pins (A0, A1, A2) select the fixed I²C-bus address and allow up to eight

devices to share the same I²C-bus/SMBus.

2. Features and benefits

 I²C-bus to parallel port expander

 Pin and function compatible with PCA9535

 Operating power supply voltage range of 1.65 V to 5.5 V
