DC Characteristics

Note: The embedded modules provide an on board supervisor circuit with a 2.93V (nominal) reset
threshold. When V
CC
falls to the threshold voltage, a reset pulse is issued, holding the
output in active state. When power rises above 2.88V, the reset remains for approximately
250 ms to allow the system clock and other circuits to stabilize.
Grounding Recommendation
It is recommended that you connect the tabs on the chassis of the Digi Connect ME / Wi-ME, and
the ground pins directly to the logic ground plane. It is also recommended that you connect the Digi
Connect ME / Wi-ME to the metal chassis of your enclosure. The idea is to provide the shortest path
or a path away from circuitry for ESD to travel to ground.
