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 µs (MRC pin left open) or more with external capacitor. The
delay is implemented by connecting the appropriately sized capacitor between the MRC pin
and V
Two of the three supplies monitored (V
factory-trimmed) thresholds (V
externally adjustable RSTIN threshold (0.626 V internal reference).
If any of the three monitored voltages drop below its factory-trimmed or adjustable
thresholds, or if MR is asserted to logic low, a RST is asserted (driven low). Once asserted,
RST is maintained at low for a minimum delay period (t
their respective thresholds and MR returns to high. These devices are guaranteed to be in
the correct reset output logic state when V
