Description

STM32WB55xx STM32WB35xx

The STM32WB55xx and STM32WB35xx integrate a high efficiency SMPS step-down

converter with automatic bypass mode capability when the VDD falls below VBORx (x=1, 2, 3,

4) voltage level (default is 2.0 V). It includes independent power supplies for analog input for

ADC and comparators, as well as a 3.3 V dedicated supply input for USB.

A VBAT dedicated supply allows the devices to back up the LSE 32.768 kHz oscillator, the

RTC and the backup registers, thus enabling the STM32WB55xx and STM32WB35xx to

supply these functions even if the main VDD is not present through a CR2032-like battery, a

Supercap or a small rechargeable battery.

The STM32WB55xx offer four packages, from 48 to 129 pins. The STM32WB35xx offer one

package, 48 pins.
