Memories and I/Os moved after Core in Features.

Table 2: Ultra-low-power STM32L071xx device features and

peripheral counts: changed number of USART for

LQFP32/UFQFPN32 and added note 3.

Removed column "I/O operation" from Table 3: Functionalities

depending on the operating power supply range and added note

related to GPIO speed.

In Section 5: Memory mapping, replaced memory mapping

schematic by reference to the reference manual.

Update note related to PA11/12 below Figure 3: STM32L071xx

LQFP100 pinout, Figure 4: STM32L071xx UFBGA100 ballout,

Figure 5: STM32L071xx LQFP64 pinout, Figure 6: STM32L071xx

UFBGA64/TFBGA64 ballout, Figure 7: STM32L071xx WLCSP49

ballout, Figure 8: STM32L071xx LQFP48 pinout and Figure 11:

STM32L071xx UFQFPN32 pinout.

Updated Figure 7: STM32L071xx WLCSP49 ballout.

Added mission profile compliance with JEDEC JESD47 in

Section 6.2: Absolute maximum ratings.

Removed CRS from Table 39: Peripheral current consumption in

Run or Sleep mode.

Updated minimum and maximum values of I/O weak pull-up

equivalent resistor (RPU) and weak pull-down equivalent resistor

(RPD) in Table 58: I/O static characteristics.

Updated minimum and maximum values of NRST weak pull-up

equivalent resistor (RPU) in Table 61: NRST pin characteristics.

Added note 2. related to the position of the external capacitor below

Figure 29: Recommended NRST pin protection.

Updated RAIN in Table 62: ADC characteristics.

Updated tAF maximum value for range 1 in Table 70: I2C analog filter

characteristics.

Removed Table 90: USART/LPUART characteristics.

NSS timing waveforms updated in Figure 34: SPI timing diagram -

slave mode and CPHA = 0 and Figure 35: SPI timing diagram - slave

mode and CPHA = 1(1).

Updated Figure 49: TFBGA64 – 64-ball, 5 x 5 mm, 0.5 mm pitch thin

profile fine pitch ball grid array package outline.

Added reference to optional marking or inset/upset marks in all

package device marking sections. Updated note below marking

schematics.
