PCA9671 2 Remote 16-bit I/O expander for Fm+ I C-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 2 families via the two-line bidirectional bus (I C-bus) and is a part of the Fast-mode Plus (Fm+) family. 2 The PCA9671 is a drop in upgrade for the PCF8575 providing higher I C-bus speeds (1 MHz versus 400 kHz) so that the output can support PWM dimming of LEDs, higher 2 I C-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. 2 The device consists of a 16-bit quasi-bidirectional port and an I C-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 2 1MHz I C-bus interface 2 Compliant with the I C-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, DHVQFN24PCA9671 NXP Semiconductors 2 Remote 16-bit I/O expander for Fm+ I C-bus with reset 3.
