Features:

– Change minimum comparator supply voltage to 1.65 V.

– Updated current consumptions in Standby, Stop and Stop with

RTC ON modes.

Updated number of GPIOs for STM32L031GxUxS in Table 2:

Ultra-low-power STM32L031x4/x6 device features and peripheral

counts.

Removed note related to preliminary consumption values in

Table 5: Functionalities depending on the working mode (from

Run/active down to standby).

Added number of fast and standard channels in Section 3.10:

Analog-to-digital converter (ADC).

Added baudrate allowing to wake up the MCU from Stop mode in

Section 3.15.2: Universal synchronous/asynchronous receiver

transmitter (USART) and Section 3.15.3: Low-power universal

asynchronous receiver transmitter (LPUART).

Changed VDDA minimum value to 1.65 V in Table 20: General

operating conditions.

Added IREFINT value for VDD=1.8 V in Table 35: Peripheral

current consumption in Stop and Standby mode.

Section 6.3.15: 12-bit ADC characteristics:

– Table 57: ADC characteristics:

Distinction made between VDDA for fast and standard

channels; added note 1.

Added note 4. related to RADC.

Updated tS and tCONV.

– Updated Table 58: RAIN max for fADC = 16 MHz for fADC =

16 MHz and distinction made between fast and standard

channels.

Added Table 66: USART/LPUART characteristics.
