Consumption comparison

The STM32L15/6xVD-X devices feature less dynamic consumption than the

STM32L15/6xxD devices, due to the advanced manufacturing technology. The power

consumptions in low-power modes are on similar levels.

Table 4 shows the differences in power consumption between the devices in the various

operating modes.
