1 Maximum leakage current occurs at maximum operating temperature. Current decreases by approximately one-half for each
8ËC to 12ËC in the temperature range from 50ËC to 125ËC.
2 Refer to Section A.1.4, âCurrent Injectionâ, for more details
3 Parameter only applies in STOP or Pseudo STOP mode.
A.1.10 Supply Currents
This section describes the current consumption characteristics of the device as well as the conditions for
the measurements.
