Description
The PCA9535 and PCA9535C are 24-pin CMOS devices that provide 16 bits of GeneralPurpose parallel
Input/Output (GPIO) expansion for I2C-bus/SMBus applications and wasdeveloped to enhance the N-X-P
Semiconductors family of I2C-bus I/O expanders. Theimprovements include higher drive capability, 5 V I/O
tolerance, lower supply current,individual I/O configuration, and smaller packaging. I/O expanders provide
a simplesolution 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 Outputselection), 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 tothe I/O configuration bits. The data for each input or output is
kept in the correspondingInput or Output register. The polarity of the read register can be inverted with the
PolarityInversion register. All registers can be read by the system master. Although pin-to-pin andI2C-bus
address compatible with the PCF8575, software changes are required due to theenhancements and are
discussed in Application Note AN469.
The PCA9535 is identical to the PCA9555 except for the removal of the internal I/Opull-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 arehigh-impedance open-drain
outputs.
The PCA9535 and PCA9535C open-drain interrupt output is activated when any inputstate differs from
its corresponding Input Port register state and is used to indicate to thesystem master that an input state
has changed. The power-on reset sets the registers totheir default values and initializes the device state
machine.Three hardware pins (A0, A1, A2) vary the fixed I2C-bus address and allow up to eightdevices
to share the same I2C-bus/SMBus.
The fixed I2C-bus address of the PCA9535and PCA9535C are the same as the PCA9555 allowing up to
eight of these devices in anycombination to share the same I2C-bus/SMBus.
