STM32L452xx
Electrical characteristics
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%, V_DD12 = 1.10 V
2. Reduced code used for characterization results provided in Table 26, Table 28, Table 30.
Table 34. Typical current consumption in Run, with different codes running from Flash,
ART enable (Cache ON Prefetch OFF) and power supplied by external SMPS
(V_DD12 = 1.05 V)
