Description
GPIO expander is useful especially for the application that is in short of IO ports.
It can
1. Control GPIO output states by I2
C write protocol.
2. Know GPIO input states by I2
C read protocol.
Furthermore,it has the interrupt function that can release CPU from polling the registers in the GPIO expander.
GPIO expander are also equipped with Built-in power on reset, 3V tolerant input,and NMOS open-drain output.
Features
1) 400Kbps, 2-Wire serial interface
2) Interrupt output
3) 20-bit General purpose input/output interface
8-bit and 12-bit IO groups are designed for different power supply
voltages from the device core voltage supply
