  CERN makes ex­ten­sive use of the World­FIP field-bus in­ter­face in the LHC and other ac­cel­er­a­tors in the pre-in­jec­tors chain. Fol­low­ing the de­ci­sion of the provider of the com­po­nents to stop the de­vel­op­ments in this field and fore­see­ing the po­ten­tial prob­lems in the sub­se­quent sup­port, CERN de­cid­ed to pur­chase the de­sign in­for­ma­tion of these com­po­nents and in-source the fu­ture de­vel­op­ments using this tech­nol­o­gy. The first in-house de­sign con­cerns a re­place­ment for the Mi­croFIP chip whose last ver­sion was man­u­fac­tured in an IC fea­ture size found to be more vul­ner­a­ble to ra­di­a­tion of high en­er­gy par­ti­cles than the pre­vi­ous ver­sions. NanoFIP is a CERN de­sign based on a Flash FPGA im­ple­ment­ing a sub­set of the func­tion­al­i­ty al­lowed by the com­mu­ni­ca­tion stan­dard, fit­ting the re­quire­ments of the dif­fer­ent users and in­clud­ing the ro­bust­ness against ra­di­a­tion as a de­sign con­straint. The de­vel­op­ment pre­sent­ed in­volved sev­er­al groups at CERN work­ing to­geth­er in the frame­work of the Open Hard­ware Repos­i­to­ry col­lab­o­ra­tion, and aim­ing at max­i­miz­ing the in­ter­op­er­abil­i­ty and re­li­a­bil­i­ty of the final prod­uct.
