SUMMARY DESCRIPTION
The STM690/704/795/802/804/805/806 Supervi-
sors are self-contained devices which provide mi-
croprocessor supervisory functions with the ability
to
non-volatize
and
LPSRAM. A precision voltage reference and com-
parator monitors the V
CC
input for an out-of-toler-
ance condition. When an invalid V
CC
condition
occurs, the reset output (RST) is forced low (or
high in the case of RST). These devices also offer
write-protect
external
a watchdog timer (except for STM704/795/806) as
well as a power-fail comparator (except for
STM795) to provide the system with an early
warning of impending power failure.
These devices are available in a standard 8-pin
SOIC package or a space-saving 8-pin TSSOP
package.

Note: 1. For STM804/805, reset output is active-high and open
drain.
