Intersil X40035
The X40030, X40031, X40034, X40035 combine power-on reset control, watchdog timer, supply voltage supervision, second and third voltage supervision, and manual reset, in one package. This combination lowers system cost, reduces board space requirements, and increases reliability. This allows the power supply and system oscillator to stabilize before the processor can execute code.| Part No. | X40035 |
