STM6519：Single push-button Smart Reset
The Smart ResetTM 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 (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 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 tSRCcauses 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 (tSRC). The reset output (RST) is asserted
after the Smart Reset input is held active for the selected tSRCdelay time. The
RSToutput remains asserted either until the
SRinput 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 tREC (i.e.
factory-programmed). The device fully operates over a broad VCCrange from 2.0 V to
5.5 V.
