STM6519ACARUB6F

STM6519ACARUB6F is a single-pin, push button Smart Reset™ device provides a useful feature which 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 (tSRC), which ensures a safe reset and eliminates the need for a specific 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. If the system still does not respond properly, continuing to keep the push-buttons closed for the extended setup time tSRC causes a hard reset of the processor through the reset output. Typical applications include mobile phones, smartphones, PDAs, e-books, MP3 players, games and portable navigation devices.
