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-  
value and keeping it asserted until V

resistor, allowing it to be left open if not used. This  
input can be driven with TTL/CMOS-logic levels or  
with open-drain/collector outputs. Connect a nor-  
mally open push-button switch from MR to GND to

output no longer sinks current, but becomes an  
open circuit. In most systems this is not a problem,  
as most MCUs do not operate below 1V. However,  
in applications where RST output must be valid  
down to 0V, a pull-down resistor may be added to  
hold the RST output low. This resistor must be  
large enough to not load the RST output, and still  
be small enough to pull the output to ground. A  
100Kresistor is recommended.  
Note: The same situation applies for the active-  
high RST of the STM810/812. A 100Kpull-up re-  
sistor to V  
should be used if RST must remain

MAXIMUM RATING  
Stressing the device above the rating listed in the  
Absolute Maximum Ratings” table may cause per-  
manent damage to the device. These are stress  
ratings only and operation of the device at these or  
any other conditions above those indicated in the  
Operating sections of this specification is not im-  
plied. Exposure to Absolute Maximum Rating con-  
ditions for extended periods may affect device  
reliability. Refer also to the STMicroelectronics  
SURE Program and other relevant quality docu-  
ments.

DC AND AC PARAMETERS  
This section summarizes the operating measure-  
ment conditions, and the DC and AC characteris-  
tics of the device. The parameters in the DC and  
AC characteristics Tables that follow, are derived  
from tests performed under the Measurement  
Conditions summarized in Table 4, Operating and  
AC Measurement Conditions. Designers should  
check that the operating conditions in their circuit  
match the operating conditions when relying on  
the quoted parameters.
