GPIO expanders

PCA9536/54/54A/55

These expanders provide a simple way to add I/O for ACPI

power switches, sensors, pushbuttons, LEDs, fans, and

functions, in a wide variety of I

The NXP PCA9554 and PCA9554A are 16-pin CMOS devices

that provide eight bits of parallel GPIO expansion. They

include four 8-bit registers: an 8-bit conﬁ guration register for

I/O selection, an 8-bit input register, an 8-bit output register,

and an 8-bit polarity-inversion register. The system master

can enable the I/O as inputs or outputs by writing to the I/O

conﬁ guration bits. Data for each input or output is kept in

the corresponding input or output register. The polarity of

the read register can be inverted using the polarity-inversion

two devices are identical except for a ﬁ xed address.

The NXP PCA9555 is a 24-pin CMOS device that provides

16 bits of parallel GPIO expansion. It has two sets of the

same 8-bit registers as the PCA9554.

The NXP PCA9536 is an 8-pin CMOS device that provides

4 bits of parallel GPIO expansion. It is identical to the PCA9554

except it uses only 4 bits of the 8-bit register space.
