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.
Features
■ 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,
900ms (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)
