This datasheet also covers the X4003 variant, as both devices belong to the same cpu supervisor family and are provided as variant models within a single manufacturer datasheet.
General Description
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.
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.
