SUMMARY DESCRIPTION
The STM809/810/811/812 MICROPROCESSOR
RESET Circuits are low-power supervisory devic-
es used to monitor power supplies. They perform
a single function: asserting a reset signal whenev-
er the V
CC
supply voltage drops below a preset
value and keeping it asserted until V
CC
has risen
above the preset threshold for a minimum period
of time (t
rec
). The STM811/812 also provide a
push-button reset input (MR).
