Smart resets eliminate dedicated reset buttons

The STM65xx family of smart reset ICs provides dual-assert

manual-reset (push-button) inputs called smart reset

inputs that make it possible to reliably resolve a system

hang or freeze condition.

Dual-assert manual-reset inputs require the user to

assert two inputs simultaneously to initiate the system

reset function (except the STM6504 which is edge

triggered). This dual-key approach is more advanced

than conventional single push-button resetting because it

prevents the system from accidentally resetting.

The STM65xx smart reset ICs allow the designer to use

existing buttons to reset a device and eliminates the need

for an unsightly reset access hole or a dedicated reset

button.

Applications

and prevent accidental resets

MP3 players

Portable navigation devices

Mobile/smartphones

Any application that requires

1 or 2 delayed push buttons
