STM6717/6718/6719/6720/STM6777/6778/6779/6780 1 Description The STM6717/18/19/20 and STM6777/78/79/80 supervisors are a family of low-voltage/low- supply current processor (micro or DSP) supervisors, designed to monitor two (or three) system power supply voltages. They are targeted at applications such as set-top boxes (STBs), portable, battery-powered systems, networking, and communication systems. All device options have a push-button-type manual reset input (MR). The STM6777/78/79/80 also includes an option which enables the user to delay the start of the manual reset process from 6 µ ...

... Interfacing to processors with bi-directional reset pins Most processors with bi-directional reset pins can interface directly to the open drain RST outputs (STM6717/19/77/79). Systems simultaneously requiring a push-pull RST output and a bi-directional reset interface can be in logic contention. To prevent this contention, connect a 4.7 kΩ resistor between RST and the processor’s reset I/O as ...
