DESCRIPTION

The PCA9535 is a 24-pin CMOS device that provide 16 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C/SMBus applications and was developed to enhance the Philips

family of I2C 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, pushbuttons, LEDs, fans, etc.

The PCA9535 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 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 PCA9535 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 address and allow up to eight devices to share the same I2C/SMBus. The fixed I2C address of the PCA9535 is the same as the PCA9554 allowing up to eight of these devices in any combination to share the same I2C/SMBus.
