STM6519AHARUB6F

STM6519AHARUB6F is a single-pin, push button Smart Reset™ device. It provides a useful feature that ensures that inadvertent short reset push-button closures do not cause system resets. This is done by implementing an extended Smart Reset input delay time, which ensures a safe reset and eliminates the need for a specifically dedicated reset button. This reset configuration provides versatility and allows the application to distinguish between a software generated interrupt and a hard system reset. When the input pushbutton is connected to the microcontroller interrupt input, and is closed for a short time, the processor can only be interrupted. Application includes mobile phones, smartphones, PDAs, e-books, MP3 players, games, portable navigation devices, any application that requires delayed reset push-button response for improved system stability.
