Description

The STM6xxx supervisors are self-contained devices which provide microprocessor

(RST) is forced low (or high in the case of RST). These devices also offer a watchdog timer

(except for STM6322/6825) and/or a push-button (MR) reset input.

These devices are available in a standard 5-pin SOT23 package.
