Cover page: changed LQFP32 size, updated core speed, added

minimum supply voltage for ADC, DAC and comparators.

ADC now guaranteed down to 1.65 V.

Updated list of applications in Section 1: Introduction. Changed number

of I2S interfaces to one in Section 2: Description.

Updated Table 2: Ultra-low-power STM32L052x6/x8 device features

and peripheral counts.

Updated RTC/TIM21 in Table 6: STM32L0xx peripherals interconnect

matrix.

Updated Table 3: Functionalities depending on the operating power

supply range.

Splitted LQFP32/UFQFPN32 pinout schematics into two distinct

figures: Figure 7 and Figure 8. Added note related to WLCSP36

package in Table 16: STM32L052x6/8 pin definitions.

Updated Section 3.4.1: Power supply schemes.

Updated VDDA in Table 25: General operating conditions.

Splitted Table Current consumption in Run mode, code with data

processing running from Flash into Table 29 and Table 30 and content

updated. Splitted Table Current consumption in Run mode, code with

data processing running from RAM into Table 31 and Table 32 and

content updated. Updated Table 33: Current consumption in Sleep

mode, Table 34: Current consumption in Low-power run mode,

Table 35: Current consumption in Low-power sleep mode, Table 36:

Typical and maximum current consumptions in Stop mode, Table 37:

Typical and maximum current consumptions in Standby mode, and

added Table 38: Average current consumption during Wakeup.

Updated Table 39: Peripheral current consumption in Run or Sleep

mode and added Table 40: Peripheral current consumption in Stop and

Standby mode.

Updated Table 47: HSI48 oscillator characteristics. Removed note 1

below Figure 21: HSE oscillator circuit diagram.

Updated tLOCK in Table 50: PLL characteristics.

Updated Table 52: Flash memory and data EEPROM characteristics

and Table 53: Flash memory and data EEPROM endurance and

retention.

Updated Table 61: I/O AC characteristics.

Updated Table 63: ADC characteristics.

Updated Figure 56: Thermal resistance and added note 1.
