PCA8575

Remote 16-bit I/O expander for I²C-bus with interrupt

Rev. 01 — 30 November 2006

Objective data sheet

1. General description

The PCA8575 provides general purpose remote I/O expansion for most microcontroller

families via the two-line bidirectional I²C-bus (serial clock (SCL), serial data (SDA)).

The device consists of a 16-bit quasi-bidirectional port and an I²C-bus interface. The

PCA8575 has a low current consumption and includes latched outputs with high current

drive capability for directly driving LEDs.

The PCA8575 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) initializes the I/Os as

inputs.

2. Features

I 400 kHz I²C-bus interface

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 8 programmable slave addresses using 3 address pins

I Readable device ID (manufacturer, device type, and revision)

I Low standby current (10 µA max.)

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

I Packages offered: SO24, SSOP24 (QSOP24), TSSOP24, HVQFN24, DHVQFN24

3. Applications

I LED signs and displays

I Servers

I Industrial control
