Electrical Specification Deviation Errata of FT90x
3.1 Revision B
3.1.1 FSOURCE Pin issue
Introduction:
The FT90x series has dedicated VPP and FSOURCE input pins as 64-bit EFUESE program source inputs.
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.
