I would like to ask whether the SFS2620HMBGBAD has undergone OTP programming. It should not be a blank die, right? Can it be used directly? Is it only the A0 revision that is a blank die and must go through OTP programming before it can be used?
Yes, the SFS2620HMBGBAD is a standard production FS2620 device that ships with OTP already programmed and can be used directly in an application. Only the A0 revision devices are blank OTP dies requiring OTP programming before use.
