PCA9539; PCA9539R

16-bit I²C-bus and SMBus low power I/O port with interrupt

and reset

Rev. 7 — 15 April 2014

Product data sheet

1. General description

The PCA9539; PCA9539R is a 24-pin CMOS device that provides 16 bits of General

Purpose parallel Input/Output (GPIO) expansion with interrupt and reset for

I²C-bus/SMBus applications and was developed to enhance the NXP Semiconductors

family of I²C-bus I/O expanders. I/O expanders provide a simple solution when additional

I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc.

The PCA9539; PCA9539R 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

The PCA9539; PCA9539R 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, replacement of A2 with RESET and a different address range.

The PCA9539; PCA9539R 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. In the PCA9539, the RESET pin causes the same reset/default I/O input

configuration to occur without de-powering the device, holding the registers and I²C-bus

state machine in their default state until the RESET input is once again HIGH. This input

requires a pull-up to V_DD. In the PCA9539R however, only the device state machine is

initialized by the RESET pin and the internal general-purpose registers remain

unchanged. Using the PCA9539R RESET pin will only reset the I²C-bus interface should

it be stuck LOW to regain access to the I²C-bus. This allows the I/O pins to retain their last

configured state so that they can keep any lines in their previously defined state and not

cause system errors while the I²C-bus is being restored.

Two hardware pins (A0, A1) vary the fixed I²C-bus address and allow up to four devices to

share the same I²C-bus/SMBus.

2. Features and benefits

 16-bit I²C-bus GPIO with interrupt and reset

 Operating power supply voltage range of 2.3 V to 5.5 V

(5.0 V  10 % for PCA9539PW/Q900 AEC-Q100 compliant devices)

 5 V tolerant I/Os
