PCA9675  
Remote 16-bit I/O expander for Fm+ I2C-bus with interrupt  
Rev. 01 — 1 February 2007  
Product data sheet  
1. General description  
The PCA9675 provides general purpose remote I/O expansion for most microcontroller  
families via the two-line bidirectional bus (I2C-bus) and is a part of the Fast-mode Plus  
family.  
The PCA9675 is a drop in upgrade for the PCF8575 providing higher Fast-mode Plus  
(Fm+) I2C-bus speeds (1 MHz versus 400 kHz) so that the output can support PWM  
dimming of LEDs, higher I2C-bus drive (30 mA versus 3 mA) so that many more devices  
can be on the bus without the need for bus buffers, higher total package sink capacity  
(400 mA versus 100 mA) that supports having all 25 mA LEDs on at the same time and  
more device addresses (64 versus 8) are available to allow many more devices on the bus  
without address conflicts.  
The device consists of a 16-bit quasi-bidirectional port and an I2C-bus interface. The  
PCA9675 has a low current consumption and includes latched outputs with high current  
drive capability for directly driving LEDs.  
It also possesses an interrupt line (INT) which can be connected to the interrupt logic of  
the microcontroller. By sending an interrupt signal on this line, the remote I/O can inform  
the microcontroller if there is incoming data on its ports without having to communicate via  
the I2C-bus. The internal Power-On Reset (POR) or software reset sequence initializes  
the I/Os as inputs.  
2. Features  
I 1 MHz I2C-bus interface  
I Compliant with the I2C-bus Fast and Standard modes  
I SDA with 30 mA sink capability for 4000 pF buses  
I 2.3 V to 5.5 V operation with 5.5 V tolerant I/Os  
I 16-bit remote I/O pins that default to inputs at power-up  
I Latched outputs with 25 mA sink capability for directly driving LEDs  
I Total package sink capability of 400 mA  
I Active LOW open-drain interrupt output  
I 64 programmable slave addresses using 3 address pins  
I Readable device ID (manufacturer, device type, and revision)  
I Low standby current  
I −40 °C to +85 °C operation  
I ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per  
JESD22-A115, and 1000 V CDM per JESD22-C101  
I Latch-up testing is done to JEDEC standard JESD78 which exceeds 100 mA
