General description

The PCA9537 is a 10-pin CMOS device that provides 4 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 PCA9537 consists of a 4-bit Conﬁguration register (input or output selection),

4-bit Input Port register, 4-bit Output Port register and a 4-bit Polarity Inversion register

(active HIGH or active LOW operation). 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 Port or Output Port register. The polarity of the Input

Port register can be inverted with the Polarity Inversion register. All registers can be read

by the system master.

The PCA9537 open-drain interrupt output (INT) 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/initialization to occur without de-powering the device.

The I2C-bus address is ﬁxed and allows only one device on the same I2C-bus/SMBus.
