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 I2C−bus/SMBus
applications.
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
register can be inverted with the Polarity Inversion register. All
registers can be read by the system master.
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.
Three hardware pins (AD0, AD1, AD2) vary the fixed I2C bus
address and allow up to 64 devices to share the same I2C−bus/SMBus.
The PCA9654EA has a different address map from the PCA9654E.

Device Address
Following a START condition, the bus master must send
the address of the slave it is accessing and the operation it
wants to perform (read or write). The address of the
PCA9654E/PCA9654EA is shown in Figure 5. Slave
address pins AD2, AD1, and AD0 choose 1 of 64 slave
addresses. To conserve power, no internal pull−up resistors
are incorporated on AD2, AD1, and AD0. Address values
can be found on Table 6 “PCA9654E Address Map” and
Table 7 “PCA9654EA Address Map”.
