PCA9672  
Remote 8-bit I/O expander for Fm+ I2C-bus with interrupt and  
reset  
Rev. 3 — 27 May 2013  
Product data sheet  
1. General description  
The PCA9672 provides general-purpose remote I/O expansion via the two-wire  
bidirectional I2C-bus (serial clock (SCL), serial data (SDA)).  
The devices consist of eight quasi-bidirectional ports, 1 MHz 30 mA drive I2C-bus  
interface, three hardware address inputs and a reset input operating between 2.3 V and  
5.5 V. 1 MHz I2C-bus Fast-mode Plus (Fm+) can support PWM dimming of LEDs, and  
higher I2C-bus drive 30 mA allows more devices to be on the bus without the need for bus  
buffers. The quasi-bidirectional port can be independently assigned as an input to monitor  
interrupt status or keypads, or as an output to activate indicator devices such as LEDs.  
The system master can read from the input port or write to the output port through a single  
register.  
The low current consumption of 2.5 A (typical, static) is great for mobile applications and  
the latched output ports have 25 mA high current sink drive capability for directly driving  
LEDs.  
The PCA9672 has two hardware address pins, allowing sixteen of each device to be on  
the same I2C-bus without the need for bus buffers, so there can be supporting up to  
128 I/Os (for example, 128 LEDs).  
The active LOW open-drain interrupt output (INT) can be connected to the interrupt logic  
of the microcontroller and is activated when any input state differs from its corresponding  
input port register state. It is used to indicate to the microcontroller that an input state has  
changed and the device needs to be interrogated without the microcontroller continuously  
polling the input register via the I2C-bus.  
The internal Power-On Reset (POR) and active LOW hardware reset pin (RESET)  
initialize the I/Os as inputs with a weak internal pull-up 100 A current source.  
2. Features and benefits  
I2C-bus to parallel port expander  
1 MHz I2C-bus interface (Fast-mode Plus I2C-bus)  
Operating supply voltage 2.3 V to 5.5 V with 5.5 V tolerant I/Os held to VDD with  
100 A current source  
8-bit remote I/O pins that default to inputs at power-up  
Latched outputs with 25 mA sink capability directly drive LEDs  
Total package sink capability of 200 mA  
Active LOW reset input  
Active LOW open-drain interrupt output
