MMPF0100 OTP Programming with custom HW

Hello

 

 

I know there are preprogrammed versions of PF0100 where certain voltage values and sequences ara available. My question is, can NXP ship these componenets programmed according to customer needs with arbitrary (within the specifications of the IC of course) settings. The problem is we are building a custom HW using this IC and iMX6Q and dont wish to go through all the programming hassle prior to the bring up.

 

Also, following AN4536, is there a hardware reference where iMX6 is interfaced with a NP PF0100 so we can take reference how to design a custom HW with an non-programmed PF?

 

Edit: Also related to the subject; Sabre board for smart devices says TP14 should be connected to 8 volts to program OTP fuses. Does this mean sabre board can be used to program a NP PF0100? If so, I cant say I understand how it works. To program, an I2C communication should be established with iMX6, but that implies the PMIC is programmed to power it up, if PMIC is programmed to power it up (and presumebly the whole board) what is the purpose of using OTP anyway? Arent they one time programibility fuses so that I can not alter their content?

 

Regards,

Mete
