GPIO ICs Series  
GPIO Expander IC  
BU8272GUW  
No.09098EAT01  
Description  
GPIO expander is useful especially for the application that is in short of IO ports.  
It can  
1. Control GPIO output states by I2C write protocol.  
2. Know GPIO input states by I2C 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
