带有复位的Fm I²C总线远程8位I/O扩展器

PCA9670D
停产

PCA9670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系列的一部分。

PCA9670是PCF8574的即用升级产品，提供更高的快速模式Plus (Fm+) 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（200 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。

PCA9670和PCF8574之间的区别是PCF8574上的中断输出由PCA9670上的1输入取代。

器件由8位准双向端口和I²C总线接口组成。PCA9670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)、硬件复位引脚(1)或软件复位序列引脚会将I/O初始化为输入。

This bus is called the Inter-IC or I2C-bus. Only two bus lines are required: a serial data line (SDA) and a serial clock line (SCL). Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 kbit/s in the Standard-mode, up to 400 kbit/s in the Fast-mode, up to 1 Mbit/s in the Fast-mode Plus (Fm+), or up to 3.4 Mbit/s in the High-speed mode.
