However, the only unique chip identifier I found so far is the 64-Bit long "<SPAN style="font-size: 10pt; line-height: 1.5em;">Device Unique ID" in the fuses</SPAN> (OCOTP_CFG0 and OCOTP_CFG1). Is there another unique ID or is the feature set wrong about the length of this unique chip identifier?</P><P></P><P>--</P><P>Stefan</P></BODY></HTML> Fri, 27 Mar 2015 09:47:20 GMT https://community.nxp.com/t5/Vybrid-Processors/128-bit-unique-chip-identifier/m-p/357253#M3664 falstaff 2015-03-27T09:47:20Z Re: 128-bit unique chip identifier https://community.nxp.com/t5/Vybrid-Processors/128-bit-unique-chip-identifier/m-p/357254#M3665 <HTML><HEAD></HEAD><BODY><P>Hi Stefan,</P><P>there is "only" 64-bit unigue ID on the Vybrid (OTP Bank 0 word 1 and 2). 128 bit can be achieved by combining this and some unused space in OTP block.</P><P>But generally just 64 unigue ID from the factory.</P><P>/Jiri</P></BODY></HTML> Tue, 31 Mar 2015 07:09:29 GMT https://community.nxp.com/t5/Vybrid-Processors/128-bit-unique-chip-identifier/m-p/357254#M3665 jiri-b36968 2015-03-31T07:09:29Z Re: 128-bit unique chip identifier https://community.nxp.com/t5/Vybrid-Processors/128-bit-unique-chip-identifier/m-p/357255#M3666 <HTML><HEAD></HEAD><BODY><P><STRONG>Vybrid Security manual <EM>Table 6-2.
