The function of VPP and FSOURCE pins provide the program indicate voltage (VPP = +1.85V, FSOURCE = +3.70V Typical) while 64-bit EFUSE burnt on-going. Otherwise, keeps FSOURCE pin floating or tiers to ground for EFUSE read operation or standby mode. Issue: The FSOURCE pin has an issue that it doesn’t support EFUSE programming on the FT90x series Revision B. Workaround: There is no workaround for this revision, will try to be fixed on next version. Hardware reference design: 1) No need change any PCB design. Keep original design for next fixed version to drop-in. Package specific: The effected packages are listed in Table 5.
