1. All values are obtained by calculation based on measurements done without SMPS and using following parameters:

SMPS input = 3.3 V, SMPS efficiency = 85%, VDD12 = 1.10 V

2. Reduced code used for characterization results provided in Table 25, Table 27, Table 29.

Table 33. Typical current consumption in Run, with different codes running from Flash,

ART enable (Cache ON Prefetch OFF) and power supplied by external SMPS

(VDD12 = 1.00 V)
