PCA9671: 带有复位的Fm+ I2C总线远程16位I/O扩展器
PCA9671通过两路双向总线（I²C总线）为大多数微控制器系列提供通用远程I/O扩展且是快速模式Plus (Fm+)系列的一部分。
PCA9671是PCF8575的直接升级产品，提供更高的I²C总线速度（1 MHz相对400 kHz）以使输出能够支持LED的PWM调光；提供更高的I²C总线驱动（30 mA相对3 mA）以使总线上可存在更多的器件而无需进行总线缓冲；提供更高的总封装灌电流能力（400 mA相对100 mA）以支持同时打开所有的25 mA LED以及提供更多可用的器件地址（64相对8）以允许总线上存在更多器件而不会发生地址冲突。
PCA9671和PCF8575之间的区别是PCF8575上的中断输出由PCA9671上的RESET输入取代。
器件由16位准双向端口和I²C总线接口组成。PCA9671具有低电流消耗且包含具备25 mA高电流驱动能力的锁存输出，用于直接驱动LED。内部上电复位(POR)、硬件复位(RESET)或软件复位序列引脚会将I/O初始化为输入。
