16 / 340 page  Description STM32L552xx 16/340 DS12737 Rev 6 - USB device FS - USB Type-C / USB power delivery controller The devices operate in the -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C junction) temperature ranges from a 1.71 to 3.6 V power supply. A comprehensive set of power-saving modes allows the design of low-power applications. Some independent power supplies are supported like an analog independent supply input for ADC, DAC, OPAMPs and comparators, a 3.3 V dedicated supply input for USB and up to 14 I/Os, which can be supplied independently down to 1.08 V. A VBAT input allows the backup of the RTC and the backup of the registers. The STM32L552xx devices offer seven packages from 48-pin to 144-pin. Table 2.
