Description
The Smart Reset™ devices provide a useful feature that ensures that inadvertent short
reset push-button closures do not cause system resets as the extended Smart Reset™
delay setup periods are implemented. Once the valid Smart Reset™ input levels and setup
delay are met, the device generates an output reset pulse for a fixed timeout period (tREC).
The typical application hookup shows that either a single Smart Reset™ input, or both reset
inputs can be connected to the applications interrupt and control both the interrupt pin and
the hard reset functions. If the push-button is closed for a short time, the processor is only
interrupted. If the system still does not respond properly, holding the push-button(s) for the
extended setup time (tSRC) causes a hard reset of the processor. The Smart Reset™
feature helps significantly increase system stability and eliminates the need for a dedicated
reset button.
The STM65xx family of Smart Reset™ devices consists of low-current microprocessor reset
circuits targeted at applications such as MP3 players, portable navigation or mobile phones,
generally any application that requires delayed reset push-button(s) response for improved
system stability. The devices in the STM65xx Smart Reset™ family include various
combinations of useful features for the targeted applications.
The STM6522 has two combined Smart Reset™ inputs (SR0 and SR1) with delayed reset
setup time (tSRC) programmed by an external capacitor on the SRC pin.
