NOTE
Operation is guaranteed when powering down until low voltage reset
assertion.
A.1.8
Power Dissipation and Thermal Characteristics
Power dissipation and thermal characteristics are closely related. The user must assure that the maximum
operating junction temperature is not exceeded. The average chip-junction temperature (T
J
) in
C can be
obtained from:
The total power dissipation P
D
can be calculated from the equation below.
below lists the power
gives an overview of the supply currents.
1
Normal operating range is 6.0V - 18V. Continuous operation at 40V is not allowed. Only transient conditions (Load Dump)
single pulse t
max
<400ms. Operation down to 3.5V is guaranteed without reset, however some electrical parameters are
specified only in the range above 4.5V.
2
The flash program and erase operations must configure f
NVMOP
as specified in the NVM electrical section.
3
Refer to f
ADCCLK
for minimum ADC operating frequency. This is derived from the bus clock.

Please refer to
Section A.1.8, “Power Dissipation and Thermal Characteristics”
