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.
Split 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 V
DDA
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. Split
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 20: HSE oscillator circuit diagram.
Updated t
LOCK
in Table 50: PLL characteristics.
