STC705-706/706P-707-708-708T/S/R-813L

µP Supervisor Circuits

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Features

Introduction

• Precision supply-voltage monitor

- 4.63V (STC706L/705, 813L, 708L/707)

- 4.38V (STC706M/706, 813M, 708M/708)

- 3.08V (STC706T, 813T, 708T)

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 complexity and

number of components required to monitor power-

supply and battery functions.

- 2.93V (STC706S, 813S, 708S)

- 2.63V (STC706R, 813R/706P, 708R)

- 2.32V (STC706Z, 813Z, 708Z)

- 2.20V (STC706Y, 813Y, 708Y)

The main functions are:

• 200ms reset pulse width

1. Asserting reset output during power-µp, power-

down and brownout conditions for µP system;

2. Detecting power failure or low-battery conditions

with a 1.25V threshold detector;

• Debounced TTL/CMOS-compatible manual-

reset input

• Independent watchdog timer 1.6sec time-out (not

available for STC707/708/708T/708S/R/Z/Y)

• Reset output signal:

3. Watchdog functions (not for STC708x).

- 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 V_CC= 1.2V

Applications

• Power-supply circuitry in µP systems
