https://community.nxp.com/t5/i-MX-Processors/PF8100EPES-EQES-OTP-issues/m-p/1345818#M180591 <P>Hi Sam</P> <P>&nbsp;</P> <P>seems there is some misunderstanding as PF8100EPES and PF8100EQES are already</P> <P>programmed parts and due to "OTP (One time programmable) memory for device configuration"</P> <P>as described in p.9 below datasheet, their configuration can not be changed.</P> <P><A

performance applications - Data sheet </STRONG></A></P> <P>For OTP burnning it is necessary to use MC33PF8100A0ES (Not programmed) part as</P> <P>described in Table 2. Ordering information.</P> <P>&nbsp;</P> <P>Best regards<BR />igor</P> Fri, 24 Sep 2021 11:12:42 GMT https://community.nxp.com/t5/i-MX-Processors/PF8100EPES-EQES-OTP-issues/m-p/1345818#M180591 igorpadykov 2021-09-24T11:12:42Z
