PCA9671  
Remote 16-bit I/O expander for Fm+ I2C-bus with reset  
Rev. 3 — 29 September 2011  
Product data sheet  
1. General description  
The PCA9671 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  
(Fm+) family.  
The PCA9671 is a drop in upgrade for the PCF8575 providing higher 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) to allow many more devices on the bus without address conflicts.  
The difference between the PCA9671 and the PCF8575 is that the interrupt output on the  
PCF8575 is replaced by a RESET input on the PCA9671.  
The device consists of a 16-bit quasi-bidirectional port and an I2C-bus interface. The  
PCA9671 has a low current consumption and includes latched outputs with 25 mA high  
current drive capability for directly driving LEDs. The internal Power-On Reset (POR),  
hardware reset pin (RESET) or software reset sequence initializes the I/Os as inputs.  
2. Features and benefits  
1 MHz I2C-bus interface  
Compliant with the I2C-bus Fast-mode and Standard-mode  
SDA with 30 mA sink capability for 4000 pF buses  
2.3 V to 5.5 V operation with 5.5 V tolerant I/Os  
16-bit remote I/O pins that default to inputs at power-up  
Latched outputs with 25 mA sink capability for directly driving LEDs  
Total package sink capability of 400 mA  
Active LOW reset input  
64 programmable slave addresses using 3 address pins  
Readable device ID (manufacturer, device type, and revision)  
Low standby current  
40 C to +85 C operation  
ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per  
JESD22-C101  
Latch-up testing is done to JEDEC standard JESD78 which exceeds 100 mA  
Packages offered: SO24, TSSOP24, HVQFN24, DHVQFN24
