PCF8575CTS: I2C总线远程16位I/O扩展器

该器件是一款硅CMOS电路。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。

器件由16位准双向端口和I²C总线接口组成。PCF8575C具有低电流消耗且包含具备高电流驱动能力的锁存输出,用于直接驱动LED。还具有中断线路(INT),可连接至微控制器的中断逻辑。通过在此线路发送中断信号,远程I/O可通知微控制器其端口上是否存在输入数据而无需通过I²C总线通信。这表示该器件是一款I²C总线从发送器/接收器。

每个来自PCF8575C的数据传输必须由偶数字节组成,第一个字节可以是P07至P00而第二个字节可以是P17至P10。第三个可以是P07至P00,等等。
