Extended operating temperature range to 125 °C.

Updated minimum ADC operating voltage to 1.65 V.

Changed number of I2S interface from 1 to 0 in Table 2: Ultra-low-

power STM32L052x6/x8 device features and peripheral counts.

Replaced USART3 by LPUART1 in Table 16: STM32L052x6/8 pin

definitions and LPUART by LPUART1 in Table 17: Alternate function

port A, Table 18: Alternate function port B, Table 19: Alternate function

port C, Table 20: Alternate function port D and Table 21: Alternate

function port H. Updated PA6 in Table 17: Alternate function port A.

Updated temperature range in Section 2: Description, Table 2: Ultra-

low-power STM32L052x6/x8 device features and peripheral counts.

Updated PD, TA and TJ to add range 3 in Table 25: General operating

conditions. Added range 3 in Table 53: Flash memory and data

EEPROM endurance and retention, Table 90: STM32L052x6/8

ordering information scheme. Update note 1 in Table 29: Current

consumption in Run mode, code with data processing running from

Flash, Table 31: Current consumption in Run mode, code with data

processing running from RAM, 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

Table 41: Low-power mode wakeup timings. Updated Figure 56:

Thermal resistance and removed note 1. Updated Figure 16: IDD vs

VDD, at TA= 25/55/ 85/105/125 °C, Low-power run mode, code running

from RAM, Range 3, MSI (Range 0) at 64 KHz, 0 WS, Figure 17: IDD

vs VDD, at TA= 25/55/ 85/105/125 °C, Stop mode with RTC enabled

and running on LSE Low drive, Figure 18: IDD vs VDD, at TA=

25/55/85/105/125 °C, Stop mode with RTC disabled, all clocks off.

Updated Table 37: Typical and maximum current consumptions in

Standby mode.

Updated SYSCFG in Table 39: Peripheral current consumption in Run

or Sleep mode.

Updated Table 40: Peripheral current consumption in Stop and Standby

mode and Table 41: Low-power mode wakeup timings.

Updated ACCHSI16 temperature conditions in Table 46: 16 MHz HSI16

oscillator characteristics. Changed ambient temperature range in note

1 below Table 47: HSI48 oscillator characteristics.

Updated VF(NRST) and VNF(NRST) in Table 62: NRST pin characteristics.

Updated Table 63: ADC characteristics and Table 65: ADC accuracy.

Added range 3 in Table 90: STM32L052x6/8 ordering information

scheme.
