Deviations Short description Errata occurs in device revision Device VCC is designed to operate between 3V3 and 5V Fault with internal 3V3 regulator. however with this errata the B supply should not be set below 4.3V for correct operation. During enumeration when load 3V3OUT does not start with load is connected to 3V3OUT no A, B, C and D output voltage is present Table 4 Electrical and Timing Errata Copyright © 2014 Future Technology Devices International Limited 3 TN_135 FT200XD Errata Technical Note Version 1.5 Document Reference No.: FT_000637 Clearance No.: FTDI# 281 3 Functional Problems of FT200XD 3.1 Revision A 3.1.1 USB Data Transfer Introduction: An issue has been identified where the transfer of data over USB stops unexpectedly. Problem: The device is put into suspend mode during a transfer of certain data patterns most notable with binary zeros. This can halt the data transfer in certain circumstances and will require the device to be reenumerated to recover. NB. It is the presence of this data pattern on the USB bus regardless of whether the data is intended for the FT200XD or other devices (e.g. a broadcast) on the bus that forces the suspend state. Workaround: This issue can be avoided by utilising the keep awake function of the chip. This will disable the USB suspend function of the chip and is therefore an intermediate workaround until revision D silicon is released with a permanent fix. NB. With the workaround the chip will never enter lower powered suspend. However the keep awake current will be approximately 3mA. To enable the keep awake function in the EEPROM, one of the CBUS pins needs to be configured as KeepAwake#. This pin then needs to be tied to ground on the PCB. The FT_Prog utility can be used to configure the CBUS pin. Package specific: The effected packages are listed in Table 5.

So far FTDI have identified ONE such host. Problem: Certain USB 3.0 Hosts exhibit reduced reset recovery times after a USB reset, which can at times be faster or close to the USB 2.0 specification limit. The USB 2.0 specification states a USB reset recovery time of 10ms and in general almost all hosts allocate a much longer period than this. The FT200XD device may not enumerate if the reset recovery time is reduced. This issue has been seen on one USB 3.0 Host controller and has not been seen on a USB 2.0 Host controller or other USB 3.0 Host controllers. Workaround: Reconnect the device to a USB 2.0 host. This issue has been seen only on one particular USB 3.0 Host controllers. Package specific: The effected packages are listed in Table 6.

Problem: During enumeration when a load is applied to the 3V3OUT pin, no output voltage is present. Workaround: The external circuitry must be powered off during enumeration of the FT200XD. A power Mosfet can be used in conjunction with the PWREN# pin. PWREN# is used to show enumeration has been successful and the external circuity can now be switched on. Package specific: The effected packages are listed in Table 11.

Package specific: The effected packages are listed in Table 12. Package Applicable (Yes/No) FT200XD Y Table 12 4.2.2 Internal 3V3 Regulator Introduction: The FT200XD uses an internal regulator to generate 3V3 from a 5V source (VCC). The source should be variable from 3V3 to 5V. Problem: The VCC supply to the regulator must not drop below 4.3V for the correct 3V3 regulated output to be produced. Workaround: VCC must not be supplied below 4.3V. This issue will be corrected at silicon revision C. Package specific: The effected packages are listed in Table 13.
