Questions and answers: IAR EWARM V5.20

and STM32F101xx/STM32F103xx medium-

density devices

Q1: How many revisions of the medium-density devices are there?

A1: Three revisions have been delivered to customers: Rev. B, Rev. Z and Rev. Y in

chronological order (Rev B -> Rev Z -> Rev Y).

Q2: Which revisions have compatibility issues with IAR EWARM V5.20?

A2: The compatibility issue is with Rev. B and Rev. Z of medium-density devices.

Q3: How can I tell which revision I am using?

A3: The revision letter is on the package. Its location is explained in the product errata sheet.

Q4: Is there any problem with my application developed with the previous

version of IAR and previous versions of STM32F101xx/STM32F103xx

medium-density devices?

A4: No, systems already developed, validated and delivered to the field with previous silicon

revisions are not affected.

Q5: Can I still use IAR EWARM V5.20 with Rev. Z or Rev. B of an

STM32F101xx/STM32F103xx medium-density device if everything works fine?

A5: No, we advise to use only Rev Y with IAR EWARM V5.20.

Q6: What are the STM32F101xx/STM32F103xx medium-density parts currently

available?

A6: Today, ST produces only Rev. Y devices, which correspond to the latest silicon revision.

Some distributors may still have stocks of previous revisions, but they are smoothly being

replaced by Rev. Y devices.

Q7: How am I sure to get only Rev. Y?

A7: The e-sampling process is explained at the beginning of the present document

(TN0067).
