PCA9554/54A/55

8- and 16-bit I

C and

SMBus I/O Port with Interrupt

Part Type Description

The PCA9554 and PCA9554A are 16-pin CMOS devices that provide

8 bits of General Purpose parallel Input/Output (GPIO) expansion for

C/SMBus applications. These I/O expanders provide a simple solu-

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

pushbuttons, LEDs, fans, etc. The parts consist of an 8-bit Configura-

tion register (Input or Output selection); 8-bit Input register, 8-bit

Output register and an 8-bit Polarity inversion register (Active high or

Active low operation). The PCA9555 is a 24-pin CMOS device, which

provides 16 bits of GPIO and consists of two 8-bit Configuration,

Input, Output and Polarity inversion registers.

The system master can enable the PCA9554/54A/55 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

Polarity Inversion Register. All registers can be read by the system mas-

ter. Although pin to pin and I

C address compatible with the PCF857X

series, software changes are required due to the enhancements and are

discussed in Application Note AN469. The PCA9554/54A/55 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. If an external hardware

reset is needed, the PCA9556/57 should be used.

Three hardware pins (A0, A1, A2) vary the fixed I

C address and allow

up to eight devices to share the same I

C/SMBus. The PCA9554A is

identical to the PCA9554 except that the fixed I

C address is different

allowing up to sixteen of these devices (eight of each) on the same

C/SMBus. The fixed I

C address of the PCA9555 is the same as the

PCA9554 allowing up to eight of these devices in any combination to

share the same I

C/SMBus.

The PCA9554/54A/55 were developed to enhance the Philips family

of I

C I/O expanders. The improvements include higher drive capability,

5V I/O tolerance, lower supply current, individual I/O configuration,

400 kHz clock frequency, and smaller packaging.
