PCA9501

8-bit I²C-bus and SMBus I/O port with interrupt, 2-kbit

EEPROM and 6 address pins

Rev. 04 — 10 February 2009

Product data sheet

1. General description

The PCA9501 is an 8-bit I/O expander with an on-board 2-kbit EEPROM.

The I/O expandable 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 conﬁguration bits in the same way as for the

PCF8574. The data for each input or output is kept in the corresponding input or output

The EEPROM can be used to store error codes or board manufacturing data for

read-back by application software for diagnostic purposes and are included in the I/O

expander package.

The PCA9501 active LOW open-drain interrupt output is activated when any input state

differs from its corresponding input port register state. It is used to indicate to the system

master that an input state has changed and the device needs to be interrogated.

The PCA9501 has six address pins with internal pull-up resistors allowing up to

64 devices to share the common two-wire I²C-bus software protocol serial data bus. The

ﬁxed GPIO address starts with ‘0’ and the ﬁxed EEPROM I²C-bus address starts with ‘1’,

so the PCA9501 appears as two separate devices to the bus master.

The PCA9501 supports hot insertion to facilitate usage in removable cards on backplane

systems.
