Initial release.

11-Jul-2014

Changed the document status to Datasheet - production

data.

Updated the following:

– Table: STM32F031x4/6 family device features and

peripheral counts,

– Figure: Clock tree,

– Figure: Power supply scheme,

– Table: Peripheral current consumption.

Replaced Table Typical current consumption in Run

mode, code with data processing running from Flash

and Table Typical current consumption in Sleep mode,

code running from Flash or RAM with Table: Typical

current consumption, code executing from Flash,

running from HSE 8 MHz crystal.

Added the LQFP32 package: updates in Section:

Description, Section: Pinouts and pin description and

Section: Package information.

Updated:

– Figure 9: STM32F031x6 memory map

– AF1 alternate functions for PA0, PA1, PA2, PA3 and

PA4 in Table 12: Alternate functions selected through

GPIOA_AFR registers for port A

– the footnote for VIN max value in Table 15: Voltage

characteristics

– the footnote for max VIN in Table 18: General

operating conditions

– Table 22: Embedded internal reference voltage with

the addition of tSTART parameter

– Table 50: ADC characteristics

– Table 53: TS characteristics: removed the min. value

for tSTART parameter

– the typical value for R parameter in Table 54: VBAT

monitoring characteristics

– the structure of Section 7: Package information.

Added:
