Initial release.

09-Oct-2009

Document status promoted from Target specification to Preliminary

data.

In Table 6: STM32F20x pin and ball definitions:

– Note 4 updated

–VDD_SA and VDD_3 pins inverted (Figure 10: STM32F20x LQFP100

pinout, Figure 11: STM32F20x LQFP144 pinout and Figure 12:

STM32F20x LQFP176 pinout corrected accordingly).

Section 6.1: Package mechanical data changed to LQFP with no

exposed pad.

01-Feb-2010

LFBGA144 package removed. STM32F203xx part numbers removed.

Part numbers with 128 and 256 Kbyte Flash densities added.

Encryption features removed.

PC13-TAMPER-RTC renamed to PC13-RTC_AF1 and PI8-TAMPER-

RTC renamed to PI8-RTC_AF2.

13-Jul-2010

Renamed high-speed SRAM, system SRAM.

Removed combination: 128 KBytes Flash memory in LQFP144.

Added UFBGA176 package. Added note 1 related to LQFP176

package in Table 2, Figure 12, and Table 92.

Added information on ART accelerator and audio PLL (PLLI2S).

Added Table 5: USART feature comparison.

Several updates on Table 6: STM32F20x pin and ball definitions and

Table 8: Alternate function mapping. ADC, DAC, oscillator, RTC_AF,

WKUP and VBUS signals removed from alternate functions and

moved to the “other functions” column in Table 6: STM32F20x pin and

ball definitions.

TRACESWO added in Figure 4: STM32F20x block diagram, Table 6:

STM32F20x pin and ball definitions, and Table 8: Alternate function

mapping.

XTAL oscillator frequency updated on cover page, in Figure 4:

STM32F20x block diagram and in Section 2.2.11: External

interrupt/event controller (EXTI).

Updated list of peripherals used for boot mode in Section 2.2.13: Boot

modes.

Added Regulator bypass mode in Section 2.2.16: Voltage regulator,

and Section 5.3.4: Operating conditions at power-up / power-down

(regulator OFF).

Updated Section 2.2.17: Real-time clock (RTC), backup SRAM and

backup registers.

Added Note Note: in Section 2.2.18: Low-power modes.

Added SPI TI protocol in Section 2.2.23: Serial peripheral interface

(SPI).
