STC706P Datasheet | Unknown Manufacturer

eatures Introduction The STC706X/813X/708X family microprocessor (µP) supervisory circuits are targeted to improve reliability and accuracy of power-supply circuitry in µP systems. These devices reduce the plexity and number of ponents required to monitor powersupply and battery functions. The main functions are: 1. Asserting reset output during power-µp, powerdown and brownout conditions for µP system; 2. Detecting power failure or low-battery conditions with a 1.25V threshold detector; 3. Watchdog functions (not for STC708x). - Precision supply-voltage monitor - 4.63V (STC706L/705, 813L, 708L/707) - 4.38V (STC706M/706, 813M, 708M/708) - 3.08V (STC706T, 813T, 708T) - 2.93V (STC706S, 813S, 708S) - 2.63V (STC706R, 813R/706P, 708R) - 2.32V (STC706Z, 813Z, 708Z) - 2.20V (STC706Y, 813Y, 708Y) - 200ms reset pulse width - Debounced TTL/CMOS-patible manualreset input - Independent watchdog timer 1.6sec time-out (not available for STC707/708/708T/708S/R/Z/Y) - Reset output signal: - Active-low only (STC705/706/706T/S/R/Z/Y) - Active-high only (STC813L/M/T/S/R/706P) - Active-high and active-low (707/708/708T/S/R) - Voltage monitor for power-fail or low battery warning - Guaranteed RESET/RESET valid at VCC = 1.2V Applications - Power-supply circuitry in µP systems Ver1.0 Data Sheet STC705-706/706P-707-708-708T/S/R-813L µP Supervisor Circuits -------------------------------------------------------------------------------------------------------------------------------------------------------------------------..
