Updated number of SPIs on cover page and in Table 2: Ultra-low-

power STM32L052x6/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 3.11: Analog-

to-digital converter (ADC).

Updated Section 3.18.2: Universal synchronous/asynchronous receiver

transmitter (USART) and Section 3.18.4: 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 3.18.2: Universal synchronous/asynchronous receiver

transmitter (USART) and Section 3.18.3: Low-power universal

asynchronous receiver transmitter (LPUART).

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

guaranteed by characterization.

Updated Table 58: I/O current injection susceptibility.

Updated Figure 6: STM32L052x6/8 WLCSP36 ballout, Figure 8:

STM32L052x6/8 UFQFPN32 pinout removing grey PA11, PA12 pins

and removing note 2.

Updated Table 55: EMI characteristics.

Changed temperature condition in Table 8: Internal voltage reference

measured values and Table 27: Embedded internal reference voltage

calibration values.

Section 6.3.15: 12-bit ADC characteristics:

– Table 63: ADC characteristics:

Distinction made between VDDA for fast and standard channels;

added note 1.

Added note 4. related to RADC.

Updated fTRIG..

Updated tS and tCONV.

– Updated equation 1 description.

– Updated Table 64: 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 66: DAC characteristics.

Added Table 73: USART/LPUART characteristics.

Updated Figure 47: LQFP48 marking example (package top view).
