Clarification on STM32F722IEK6 (UFBGA176+25) Pinout and Power Supply Scheme

shubham_patayane · ‎2025-04-27

Hi everyone,

I'm currently designing a custom board based on the STM32F722, and I came across something I need clarification on.
According to the STM32F722 datasheet, there is no device listed in the UFBGA176+25 package. However, when searching online (Buy STM32F722IEK6 - ST Online Store), I found a part labelled STM32F722IEK6.

Unfortunately, I can't seem to find a dedicated pinout or ballout diagram for this specific part.
I'm assuming that since the package is UFBGA176+25, the pinout would be similar (or identical) to that of the STM32F723xx series with the same package.

If that assumption is correct, would it also mean that the power supply scheme should follow the STM32F723 diagrams? (i.e., including pins like VDD12OTGHS, OTG_HS_REXT, etc., which are not shown in the STM32F722 typical power scheme?)

I just want to make sure before proceeding with the design.
If anyone has worked with the STM32F722IEK6 in UFBGA176+25 or can confirm if it mirrors the STM32F723xx pinout and power supply design, I would really appreciate your input!

Thanks in advance for the help!

Hello,

That will be reported internally. Internal ticket number 208701 was submitted (not accessible by the community members).

F723 UFBGA176 Pinout is provided in the figure 25. So figure 24 is specific to F722 UFBGA176.

The STM32F722 datasheet shows this pinout. The datasheet is shared with the F723.

Datasheet - STM32F722xx STM32F723xx - Arm<Sup>®</Sup> Cortex<Sup>®</Sup>-M7 32b MCU+FPU, 462DMIPS, up to 512KB Flash 256+16+4KB RAM, USB OTG HS/FS, 18 TIMs, 3 ADCs, 21 com IF

There is no VDD12OTGHS or OTG_HS_REXT pin on the F722.

Can you please point me to the correct page number? I can't find STM32F722XX UFBGA176 Pinout.

Table 10 has the pinout. I suspect figure 24 is mislabeled and is F722xx specific.

Thanks for the update. I will use Figure 24 as STM32F722 UFBGA176 pinout.
