Overview

X4003, X4005 CPU Supervisor NOc1NTo-8nOR8taE8Rc-CEItNOCoTMOuErMMRTMESeNIcELhDNonEDriDcEwaDFlwOSRwRuE.ipPnNpLtEeoArWrsCt iCElD.ceMEonSEmtIeNG/rTtNsacSt DATASHEET FN8113 Rev 2.00 June 30, 2008 These devices combine three popular functions; Power-on Reset Control, Watchdog Timer and Supply Voltage Supervision.

This combination lowers system cost, reduces board space requirements and increases reliability.

Applying power to the device activates the power-on reset circuit which holds RESET/RESET active for a period of time.

Key Features

Selectable watchdog timer - Select 200ms, 600ms, 1.4s, off.
Low VCC detection and reset assertion - Five standard reset threshold voltages nominal 4.62V, 4.38V, 2.92V, 2.68V, 1.75V - Adjust low VCC reset threshold voltage using special programming sequence - Reset signal valid to VCC = 1V.
Low power CMOS - 12µA typical standby current, watchdog on - 800nA typical standby current watchdog off - 3mA active current.
400kHz I2C interface.
1.8V to 5.5V po.
