The Smart Reset TM devices provide 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 (t SRC ), 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 push-button 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 t SRC causes a hard reset of the processor through the reset output. The STM6519 has one Smart Reset input ( SR ) with preset delayed Smart Reset setup time (t SRC ). The reset output ( RST ) is asserted after the Smart Reset input is held active for the selected t SRC delay time. The RST output remains asserted either until the SR input goes to inactive logic level (i.e. neither fixed nor minimum reset pulse width is set) or the output reset pulse duration is fixed for t REC (i.e. factory-programmed). The device fully operates over a broad V CC range from 2.0 V to 5.5 V.
