STM65xx Smart Reset ICs

STMicroelectronics' STM65xx family of Smart Resets™ consists of low power microprocessor reset circuits designed to provide an extended input delay period on single or dual Smart Reset inputs. A reset is asserted when valid Smart Reset input conditions (combined push button press) and set up time delays are met, with the aim of ensuring a safe reset and eliminating the need for a dedicated reset button. In a typical application, the Smart Reset inputs are connected to the interrupt lines, to allow the control of both the interrupt and the hard reset function. A short push sends an interrupt to the micro, a push longer than the setup time causes a hard reset.
