NOTE:
Please refer to the temperature rating of the device (C, V, M) with regards to the
ambient temperature T_A and the junction temperature T_J. For power dissipation
calculations refer to Section A.1.8 Power Dissipation and Thermal
Characteristics.

NOTES:
1. The device contains an internal voltage regulator to generate the logic and PLL supply out of the I/O supply. This
applies when this regulator is disabled and the device is powered from an external source.
2. Some blocks e.g. ATD (conversion) and NVMs (program/erase) require higher bus frequencies for proper oper-
ation.
3. See bus speed option at Table 0-1 Derivative Differences
4. Please refer to Section A.1.8 Power Dissipation and Thermal Characteristics for more details about the rela-
tion between ambient temperature T_A and device junction temperature T_J.
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:
TJ = TA + (PD • Θ_JA)
TJ = Junction Temperature, [°C ]
TA = Ambient Temperature, [°C ]
