Updated number of SPIs on cover page and in Table 1: Ultra-low-power

STM32L053x6/x8 device features and peripheral counts.

Changed minimum comparator supply voltage to 1.65 V on cover page.

Added number of fast and standard channels in Section 3.12: Analog-

to-digital converter (ADC).

Changed LCD_VLCD1 into LCD_VLCD2 in Section 3.13.2: VLCD

voltage monitoring.

Updated Section 3.19.2: Universal synchronous/asynchronous receiver

transmitter (USART) and Section 3.19.4: Serial peripheral interface

(SPI)/Inter-integrated sound (I2S) to mention the fact that USARTs with

synchronous mode feature can be used as SPI master interfaces.

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

Section 3.19.2: Universal synchronous/asynchronous receiver

transmitter (USART) and Section 3.19.3: Low-power universal

asynchronous receiver transmitter (LPUART).

In Section 6: Electrical characteristics, updated notes related to values

guaranteed by characterization.

Section 6.3.15: 12-bit ADC characteristics:

– Table 62: ADC characteristics:

Distinction made between VDDA for fast and standard channels;

added note 1

Added note 4 related to RADC.

Updated fTRIG. and VAIN maximum value; added VREF+.

Updated tS and tCONV.

– Updated equation 1 description.

– Updated Table 63: RAIN max for fADC = 16 MHz for fADC = 16 MHz

and distinction made between fast and standard channels.

Updated RO and added Note 2 in Table 65: DAC characteristics.

Added Table 72: USART/LPUART characteristics.

Updated Figure 45: LQFP48 marking example (package top view).
