PCA9535; PCA9535C

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

Rev. 05 — 15 September 2008

Product data sheet

1. General description

The PCA9535 and PCA9535C are 24-pin CMOS devices that provide 16 bits of General

Purpose parallel Input/Output (GPIO) expansion for I²C-bus/SMBus applications and was

developed to enhance the NXP Semiconductors family of I²C-bus I/O expanders. The

improvements include higher drive capability, 5 V I/O tolerance, lower supply current,

individual I/O conﬁguration, and smaller packaging. I/O expanders provide a simple

solution when additional I/O is needed for ACPI power switches, sensors, push buttons,

LEDs, fans, etc.

The PCA9535 and PCA9535C consist 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. Although pin-to-pin and

I²C-bus address compatible with the PCF8575, software changes are required due to the

enhancements and are discussed in Application Note AN469.

The PCA9535 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.

The PCA9535C is identical to the PCA9535 except that all the I/O pins are

high-impedance open-drain outputs.

The PCA9535 and PCA9535C 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.

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

devices to share the same I²C-bus/SMBus. The ﬁxed I²C-bus address of the PCA9535

and PCA9535C are the same as the PCA9555 allowing up to eight of these devices in any

combination to share the same I²C-bus/SMBus.

I 5 V tolerant I/Os
