The
G
denotes specifications which apply over the full operating
temperature range.
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2:
All voltage values are with respect to GND.

Note 3:
The output pins SRST and RST have weak internal pull-ups to
V
CC3
of 6
μ
A typ. However, external pull-up resistors may be used when
faster rise times are required.
Note 4:
The V
CC5
reset override voltage is valid for an operating range less
than approximately 4.15V. Above this point the override is turned off and
the V
CC5
pin functions normally.
