| 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 VSS(typical 4 s delay with a 3.3 μF capacitor). Two of the three supplies monitored (VCC1and VCC2) have fixed (customer-selectable, factory-trimmed) thresholds (VRST1and VRST2). The third voltage is monitored using an externally adjustable RSTIN threshold (0.626 V internal reference).
