Appendix A Electrical Characteristics
A.1.7 Operating Conditions
This chapter describes the operating conditions of the devices. Unless otherwise noted those conditions
apply to all the following data.
NOTE
Instead of specifying ambient temperature all parameters are specified for
the more meaningful silicon junction temperature. For power dissipation
calculations refer to Section A.1.8, “Power Dissipation and Thermal
Characteristics”

1. The device contains an internal voltage regulator to generate the logic and PLL supply out of the I/O supply. The operating
conditions apply when this regulator is disabled and the device is powered from an external source.
Using an external regulator, with the internal voltage regulator disabled, an external LVR must be provided.
2. Some blocks e.g. ATD (conversion) and NVMs (program/erase) require higher bus frequencies for proper operation.
