PCA9500  
8-bit I2C-bus and SMBus I/O port with 2-kbit EEPROM  
Rev. 4.1 — 5 May 2017  
Product data sheet  
1. General 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 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  
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 eight  
devices to share the common two-wire I2C software protocol serial data bus. The fixed  
GPIO I2C-bus address is the same as the PCF8574 and the fixed EEPROM I2C-bus  
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.  
2. Features and benefits  
Eight general purpose input/output expander/collector  
Drop-in replacement for PCF8574 with integrated 2-kbit EEPROM  
Internal 256 8 EEPROM  
Self timed write cycle  
4 byte page write operation  
I2C-bus and SMBus interface logic  
Internal power-on reset  
Noise filter on SCL/SDA inputs  
Three address pins allowing up to eight devices on the I2C-bus/SMBus  
No glitch on power-up  
Supports hot insertion  
Power-up with all channels configured as inputs  
Low standby current
