Description
The STM690/704/795/802/804/805/806 supervisors are self-contained devices which
provide microprocessor supervisory functions with the ability to non-volatize and write-
protect external LPSRAM. A precision voltage reference and comparator monitors the V
input for an out-of-tolerance condition. When an invalid V
output (RST) is forced low (or high in the case of RST). These devices also offer 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.
