DESCRIPTION
The PCA9500 is an 8-bit I/O expander with an on-board 2-kbit
EEPROM.
The I/O expander’s eight quasi bidirectional data pins can be
independently assigned as inputs or outputs to monitor board level
status or activate indicator devices such as LEDs. The system
master writes to the I/O configuation bits in the same way as for the
PCF8574. The data for each Input or Output is kept in the
corresponding Input or Output register. The system master can read
all registers.
The EEPROM can be used to store error codes or board
manufacturing data for read-back by application software for
diagnostic purposes and is included in the I/O expander package.
The PCA9500 has three address pins with internal pull-up resistors
allowing up to 8 devices to share the common two-wire I2C software
protocol serial data bus. The fixed GPIO I2C address is the same as
the PCF8574 and the fixed EEPROM I2C address is the same as
the PCF8582C-2, so the PCA9500 appears as two separate devices
to the bus master.
The PCA9500 supports hot insertion to facilitate usage in removable
cards on backplane systems.
The PCA9501 is an alternative to the functionally similar PCA9500
for systems where a higher number of devices are required to share
the same I2C-bus or an interrupt output is required.
