Revision
Changes
Features:
– Change minimum comparator supply voltage to 1.65 V.
– Updated current consumptions in Standby, Stop and Stop with
RTC ON modes.
Removed note related to preliminary consumption values in
Table 5: Functionalities depending on the working mode (from
Run/active down to standby).
Added number of fast and standard channels in Section 3.10:
Analog-to-digital converter (ADC).
Added baudrate allowing to wake up the MCU from Stop mode in
Section 3.16.2: Universal synchronous/asynchronous receiver
transmitter (USART) and Section 3.16.3: Low-power universal
asynchronous receiver transmitter (LPUART).

Changed V_DDA minimum value to 1.65 V in Table 20: General
operating conditions.
Added I_REFINT value for V_DD=1.8 V in Table 35: Peripheral
current consumption in Stop and Standby mode.
Section 6.3.15: 12-bit ADC characteristics:
– Table 57: ADC characteristics:
Distinction made between V_DDA for fast and standard
channels; added note 1.
Added note 4. related to R_ADC.
Updated t_S and t_CONV.
– Updated Table 58: RAIN max for fADC = 16 MHz for f_ADC =
16 MHz and distinction made between fast and standard
channels.
Added Table 66: USART/LPUART characteristics.
Added STM32L041E6 part number.
Added reference to optional marking or inset/upset marks in all
package device marking sections.
Removed note related to WLCSP25 preliminary ballout in
4
Table 15: Pin definitions. Changed aaa, bbb, ccc, ddd and eee
data from minimum to maximum values in Table 74: WLCSP25 -
2.097 x 2.493 mm, 0.400 mm pitch wafer level chip scale
mechanical data.
Added LQFP48 device marking, LQFP32 device marking,
UFQFPN28 device marking and TSSOP20 device marking.
