PCA9671

Remote 16-bit I/O expander for Fm+ I

C-bus with reset

Rev. 01 — 20 December 2006

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 (I

C-bus) and is a part of the Fast-mode Plus

(Fm+) family.

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

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.

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

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, 200 V MM per

JESD22-A115, and 1000 V CDM per JESD22-C101

Latch-up testing is done to JEDEC standard JESD78 which exceeds 100 mA

Packages offered: SO24, SSOP24, QSOP24, TSSOP24, HVQFN24, DHVQFN24
