07-May-2018

Updated Arm logo and added Arm word mark notice in Section 1:

Introduction.

Removed Cortex logo.

Updated Table 5: Functionalities depending on the working mode

(from Run/active down to standby) to change I2C functionality to

disabled in Low-power Run and Low-power Sleep modes.

Section 4: Pin descriptions:

– Changed PC14-OSC_IN into PC14-OSC32_IN in Figure 11:

STM32L071xx UFQFPN32 pinout.

– Extended Figure 6 to UFBGA64.

– Added UFBGA64 in Table 15: STM32L071xxx pin definition (same

pinout as TFBGA64

– Swapped E5 and E6 signals for UFBGA64/TFBGA64.

– Changed USARTx_RTS, USARTx_RTS_DE into

USARTx_RTS/USARTx_DE, and LPUART1_RTS,

LPUART1_RTS_DE into LPUART1_RTS/LPUART1_DE in

Table 15: STM32L071xxx pin definition and in all alternate function

tables.

Updated power dissipation (PD) in Table 25: General operating

conditions to add UFBGA64 package.

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

characteristics.

Added Section 7.4: UFBGA64 package information. Added

UFBGA64 in Table 89: Thermal characteristics and Figure 67:

Thermal resistance

Updated Figure 64: UFQFPN32 - 32-pin, 5x5 mm, 0.5 mm pitch ultra

thin fine pitch quad flat package outline and added note related to

exposed pad; updated Table 88: UFQFPN32 - 32-pin, 5x5 mm,

0.5 mm pitch ultra thin fine pitch quad flat package mechanical data.

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

profile fine pitch ball grid array package outline, Figure 50: TFBGA64

– 64-ball, 5 x 5 mm, 0.5 mm pitch, thin profile fine pitch ball ,grid

array recommended footprint and Figure 82: TFBGA64

recommended PCB design rules (0.5 mm pitch BGA).

31-Aug-2018

Updated Table 15: STM32L071xxx pin definition.

14-Nov-2019

Added UFQFPN48 package.

Removed R10K and R400K from Table 67: Comparator 1

characteristics.

Updated paragraph introducing all package marking schematics to

add the new sentence “The printed markings may differ depending

on the supply chain.”
