Features

Introduction

• Precision supply-voltage monitor

- 4.63V (STC8xxL, STC634xL)

The STCxxx 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.

- 4.38V (STC8xxM, STC634xM)

- 3.08V (STC8xxT, STC634xT)

- 2.93V (STC8xxS, STC634xS)

- 2.63V (STC8xxR, STC634xR)

- 2.32V (STC8xxZ, STC634xZ)

The main functions are:

- 2.20V (STC8xxY, STC634xY)

• 200ms reset pulse width

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

down and brownout conditions for µP system;

2. Detecting power failure or low-battery conditions

with a 1.25V threshold detector;

3. Watchdog functions;

• Debounced CMOS-compatible manual-reset input

(811, 812, 823, 825, 6342-6344)

• Reset Output Signal for Watchdog and Power

Abnormal, Manual Reset

4. Manual reset.

• Reset Push-Pull output (STC809,811,823,

824,825,6342,6345)

Applications

• Reset Open-Drain output (STC803/6343)

• Voltage monitor for power-fail or low battery warning

• Guaranteed RESET/RESET valid at V_CC= 1.0V

• Power-supply circuitry in µP systems
