This is I2C serial interface 16 bit I/O Expander Serial Module.

MCP23017 can convert 16-bit parallel data into serial data of IIC interface and convert each other.

Internal integrated power-on reset (POR) circuit reset to device default state.

Two opposite programmable interrupt source outputs.

Polarity flip register configures GPIO input polarity.
