Verifying the SBCFS26 OTP Configuration

[Sivahari]

Hi Nxp,

I am using SBC MFS2613AMDA6. 

I am aware that OTP Configuration can be done using a separate tool by changing voltage in debug pin. Is it possible to read OTP Configuration as like reading the Failsafe registers?

If I could be able to read the OTP configuration then where i can refer the address of those registers?

Thanks for your support.

Hi,

For the MFS2613AMDA6, which is our standard pre‑programmed FS26 device, the OTP configuration is fixed at production.

The complete OTP configuration for this device is documented in the attached Configuration Report, which summarizes all OTP‑defined parameters.

Hi Tomas,

It is really good to read OTP Configurations manually and understand the threshold value for each fault like (OV, UV etc).

But Is it possible to read those configurations through SPI as like fail safe/main register?

Thanks for clarifications.

Hi,

The FS26 provides an OTP readback mechanism only in Test/OTP mode, using mirror registers. This mechanism is intended for manufacturing, ATE and OTP programming verification and is not available during normal operation.

As I mentioned earlier, for the MFS2613AMDA6 the OTP configuration is fixed and the authoritative reference is the provided Configuration Report.

BRs, Tomas
