PIN DESCRIPTIONS
See
Figure 2., Logic Diagram
and
Table 2., Signal
Names
for a brief overview of the signals connect-
ed to this device.
Active-Low RST Output (Push-pull).
Pulses
low when V
CC
drops below V
RST
, and stays low as
long as V
CC
is below the reset threshold. It re-
mains low for t
rec
after V
CC
rises above the reset
threshold.
Active-Low RST Output (Open Drain).
Pulses
low when V
CC
drops below V
RST
, and stays low as
long as V
CC
is below the reset threshold. It re-
mains low for t
rec
after V
CC
rises above the reset
threshold. RST output has an internal 5.5k
pull-
up resistor.
Active-high RST Output (Push-pull).
Pulses
high when V
CC
drops below V
RST
, and stays high
as long as V
CC
is below the reset threshold. It re-
mains high for t
rec
after V
CC
rises above the reset
threshold.
Active-Low RST Output (Open Drain with inter-
nal 5.5k
pull-up) with Manual Reset Detect.
Pulses low when V
CC
drops below V
RST
, or RST
is externally pulled low for at least 1.5μs. It re-
mains low for t
PBRST
after V
CC
rises above the re-
set threshold, or after the external manual reset is
released (see
Figure 10., page 8
). RST output has
an internal 5.5k
pull-up resistor.

Ground, is the reference for the power sup-
ply. It must be connected to the system ground.
