Updated all pinout/ballout schematics to highlight pin/ball supplied

through VDD_USB.

Updated current consumption in Run mode in Section : Features.

Renamed BOOT1 into nBOOT1.

Changed USARTx_RTS into USARTx_RTS_DE and LPUARTx_RTS

into LPUARTx_RTS_DE.

Updated VLCD in Section 3.12: Analog-to-digital converter (ADC)

ADC no more available in Low-power run and Low-power Sleep modes

in Table 4: Functionalities depending on the working mode (from

Run/active down to standby).

Updated Figure 3: STM32L053x6/8 LQFP64 pinout - 10 x 10 mm,

Figure 4: STM32L053x6/8 TFBGA64 ballout - 5x 5 mm and Figure 5:

STM32L053x6/8 LQFP48 pinout - 7 x 7 mm. Changed I/O structure for

PC5 and modified E5 and E6 signals for TFBGA64 in Table 15:

STM32L053x6/8 pin definitions.

Added ΣIVDD_USB and updated ΣIIO(PIN) in Table 22: Current

characteristics

Updated VDD_USB in Table 22: Current characteristics.

Changed temperature condition in Table 7: Internal voltage reference

measured values and Table 26: Embedded internal reference voltage

calibration values.

Updated TCoeff in Table 27: Embedded internal reference voltage.

Added note related to Standby mode in Table 39: Peripheral current

consumption in Stop and Standby mode.

Updated Figure 14: 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 15: IDD vs VDD, at TA= 25/55/ 85/105/125 °C,

Stop mode with RTC enabled and running on LSE Low drive and

Figure 16: IDD vs VDD, at TA= 25/55/85/105/125 °C, Stop mode with

RTC disabled, all clocks OFF.

Updated Table 40: Low-power mode wakeup timings.

Updated MSI oscillator temperature frequency drift in Table 48: MSI

oscillator characteristics.

Updated Table 62: ADC characteristics, Table 54: EMI characteristics

and Table 55: ESD absolute maximum ratings.

Added tUP_LDO in Table 62: ADC characteristics.

Updated Table 57: I/O current injection susceptibility, Table 58: I/O

static characteristics (Ilkg) and Table 60: I/O AC characteristics.

Section : I2C interface characteristics: updated introduction and

Table 71: I2C analog filter characteristics.

Updated Figure 31: SPI timing diagram - slave mode and CPHA = 0.

Added Section : Device marking for LQFP64, updated Figure 42:

TFBGA64 marking example (package top view) and Figure 45:

LQFP48 marking example (package top view) as well as notes below

schematics.
