SUMMARY 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, batterypowered systems, networking, and communication systems.
FEATURES SUMMARY
■ PRIMARY SUPPLY (VCC1) MONITOR.
FIXED (FACTORY-PROGRAMMED) RESET
THRESHOLDS: 4.63V TO 1.58V
■ SECONDARY SUPPLY (VCC2) MONITOR
(STM6717/18/19/20/77/78).
FIXED (FACTORY-PROGRAMMED) RESET
THRESHOLDS: 3.08V TO 0.79V
■ TERTIARY SUPPLY MONITOR (USING
EXTERNALLY ADJUSTABLE RSTIN):
0.626V INTERNAL REFERENCE
■ RST OUTPUTS (PUSH-PULL OR OPEN
DRAIN); STATE GUARANTEED IF VCC1 OR
VCC2 ≥ 0.8V
■ RESET DELAY TIME (trec) ON POWER-UP:
– 210ms (typ)
■ MANUAL RESET INPUT (MR)
■ OPTIONAL DELAYED MANUAL RESET
INPUT (MRC) WITH EXTERNAL
CAPACITOR (STM6777/78/79/80)
■ LOW SUPPLY CURRENT - 11µA (TYP),
VCC1 = VCC2 = 3.6V
■ OPERATING TEMPERATURE:
–40°C to 85°C (Industrial Grade)
