PCA9654E, PCA9654EA

8-bit I/O Expander for I²C

Bus and SMBus with

Interrupt

The PCA9654E/PCA9654EA provides 8 bits of General Purpose

parallel Input/Output (GPIO) expansion for I C−bus/SMBus

applications.

MARKING

The PCA9654E/PCA9654EA consists of 8−bit Configuration

(Input or Output selection), Input, Output and Polarity Inversion

(active HIGH or active LOW operation) registers. The system master

may set 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

registers can be read by the system master.

CASE 751B

The PCA9654E/PCA9654EA open−drain interrupt (INT) 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.

CASE 948F

Three hardware pins (AD0, AD1, AD2) vary the fixed I C bus

address and allow up to 64 devices to share the same I C−bus/SMBus.

The PCA9654EA has a different address map from the PCA9654E.
