Overview
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 latc...
