GPIO Expander IC
BU1850MUV
No.09098EAT02
●Description GPIO expander is useful especially for the application that is in short of IO ports. It can 2 1. Control GPIO output states by I C write protocol. 2 2. Know GPIO input states by I 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) An 8-Port General purpose input/output interface 150kΩPull-down resistance. 2) NMOS Open-drain output interrupt controller with up to 1us pulse noise filter and bit mask function for individual GPIO port.
