35. Electrical Characteristics
35.1 Absolute Maximum Ratings*
Notes: 1. 5V tolerant pins, see Section ”Peripheral Multiplexing on I/O lines” on page 10
2. V
VDD
corresponds to either V
VDDIN
or V
VDDIO
, depending on the supply for the pin. Refer to Section on page 10 for details.
35.2 Supply Characteristics
The following characteristics are applicable to the operating temperature range: T
A
= -40°C to
85°C, unless otherwise specified and are valid for a junction temperature up to T
J
= 100°C.
Please refer to Section 6. ”Supply and Startup Considerations” on page 39.
Table 35-1. Absolute Maximum Ratings
Operating temperature..................................... -40C to +85C
*NOTICE: Stresses beyond those listed under
“Absolute Maximum Ratings” may cause
permanent damage to the device. This is
a stress rating only and functional opera-
tion of the device at these or other condi-
tions beyond those indicated in the
operational sections of this specification is
not implied. Exposure to absolute maxi-
mum rating conditions for extended peri-
ods may affect device reliability.
