DESCRIPTION

The PCA9536 is 8-pin CMOS devices that provides 4 bits of

General Purpose parallel Input/Output (GPIO) expansion for

family of I

@C I/O expanders. I/O expanders provides a simple

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

sensors, pushbuttons, LEDs, fans, etc.

The PCA9536 consists of a 4-bit Configuration register (Input or

Output selection); 4-bit Input register, 4-bit Output register and an

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 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.

The power-on reset sets the registers to their default values and

initializes the device state machine.
