Description: The MCP23017 is capable of converting 16-bit parallel data to serial data of the IIC interface and converting each other. An internal integrated power-on reset (POR) circuit is reset to the device's default state. Two independent programmable interrupt source outputs. The polarity toggle register configures the GPIO input polarity and can also be configured as an output. It can be set to use a pull-up resistor, and the IO configured as an input can use the interrupt function. The IO port has strong driving capability, and the current sinking and pulling current can reach 25mA. Parameter Performance: Operating temperature range: -40 ° C ~ 85 ° C Working voltage 3.0V~5.5V IIC communication frequency: up to 1.7MHz Working current: 1uA Size: 65x19mm M3 mounting hole Pin Interface: IIC slave device address VCC: power supply pin; INTA: A port interrupt output; port interrupt can be set to low level interrupt, high level interrupt, level change interrupt INTB: B port interrupt output; port interrupt can be set to low level interrupt, high level interrupt, level change interrupt SCL: IIC clock signal line SDA: IIC data signal line /RESET: Low level reset device A0, A1, A2: IIC device address configuration pin, default 0100000x, IIC bus can expand 8 identical devices, realize up to 128 IO expansion GPA0~GPA7: A port 8-bit input and output pin (default input mode) GPB0~GPB7: B port 8-bit input and output pin (default input mode)
