  Part Change Notice #10853: CFA635 series Firmware revision 2.1.

  Products Affected:	CFA635-YYE-KS, CFA635-TMF-KS, CFA635-TFE-KS, CFA635-TMF-KL, CFA635-TFE-KU, CFA635-YYE-KL, XES635BK-TFE-KU, XES635BK-TMF-KU, XES635BK-YYE-KU, CFA635-TMF-KU, CFA635-YYE-KU
  Date Issued:	May 3, 2017
  Summary:	CFA635 series Firmware revision 2.1.
  Last revision:	2.0
  Description:	The CFA635 series of advanced display modules will be changing from the previous firmware revision of 2.0 to the new firmware revision 2.1.
  Reason:	As part of our continuous improvement, the firmware has been updated for use with the hardware v1.5.
  Impact:	The new firmware is designed with a priority of backward compatibility. The following commands will differ from earlier versions: Command 1 (0x01) - Get Hardware and Firmware Version This command will report the following strings: Serial Versions (KS) - CFA635: h1.5,f2.1 USB Versions (KU) - CFA635: h1.5 f2v1 Commands 18,19 and 20, which control the temperature sensors on the FBSCAB, have been limited to support the FBSCAB's maximum of 16 temperature sensors.
  Recommendation:	Design changes have been made to maximize backward compatibility. For most applications, the CFA635 hardware revision 1.5 will be a form and fit replacement. If your application uses ATX power supply control, fan control, or temperature measurement through the SCAB, you will need change to the equivalent FBSCAB components. We recommend testing the new version CFA635 in your system to verify compatibility.
  Availability:	CFA635 firmware version 2.1 will begin shipping installed in hardware version 1.5 in the second quarter of 2017 after the inventory of hardware version 1.2 is depleted.

  Part Change Notice #10852: CFA635 series Hardware revision 1.5

  Products Affected:	CFA635-YYE-KS, CFA635-TMF-KS, CFA635-TFE-KS, CFA635-TMF-KL, CFA635-TFE-KU, CFA635-YYE-KL, XES635BK-TFE-KU, XES635BK-TMF-KU, XES635BK-YYE-KU, CFA635-TMF-KU, CFA635-YYE-KU
  Date Issued:	May 3, 2017
  Summary:	CFA635 series Hardware revision 1.5
  Last revision:	1.2
  Description:	The CFA635 series of advanced display modules will be changing from the previous hardware revision 1.2 to the new hardware revision 1.5.
  Reason:	As part of our continuous improvement, the processor and PCB layout have been changed to improve availability, manufacturability, and quality
  Impact:	The revised CFA635 series has Wide Temperature (-20°C to +70°C) operating range. Part numbers have changed accordingly: TMF series modules will become TML series. TFE series modules will become TFK series. YYE series modules will become YYK series. The CFA635 series now supports a single FBSCAB. The SCAB is no longer supported: All four fans may be used on serial (-KS) and logic level (-KL) modules. Maximum temperature sensors is 16. ATX power supply control functions previously supported by J8 on the SCAB are now supported by H1 on the CFA-635. The power supply and backlight circuits have been improved: The backlight driver is a constant current design-the backlight current and brightness are now insensitive to supply voltage variations. The incoming power supply range is 2.5v to 5.5v, so the CFA635 can easily be used in 3.3v systems. The yellow backlight of the CFA635-YYK series is redesigned to improve brightness. ATX functions supported by J8 on the SCAB are now supported by H1. Command 1 (0x01) - Get Hardware and Firmware Version This command will report the following strings: Serial Versions (KS) - CFA635 h1.5,f2.1 USB Versions (KU) - CFA635 h1.5,f2.1 The command set, fan electrical specifications, temperature electrical specifications and mechanical dimensions are unchanged.
  Recommendation:	Design changes have been made to maximize backward compatibility. If your application uses ATX power supply control, fan control, or temperature measurement through the SCAB, you will need to change to the equivalent FBSCAB components. We recommend testing the new version CFA635 in your system to verify compatibility.
  Availability:	CFA635 hardware version 1.5 will begin shipping in the second quarter of 2017, after the inventory of version 1.2 is depleted.

  Date Issued:	September 25, 2012
  Summary:	Parts bundled with, and options for WRUSBY11 will now be bundled with and have options for WRUSBY33.
  Description:	The WRUSBY33 cable is replacing the WRUSBY11 cable as our standard offering for product bundles and cable options for an internal USB connection for our line of intelligent modules. The WRUSBY11 has four individual connectors for +5v, -Data, +Data, and Ground. WRUSBY11 Product Page: https://www.crystalfontz.com/product/wrusby11-usb-motherboard-cable Reason Based on customer requests and feedback, the WRUSBY33 has a much simpler connection to the main board of a system with a 0.100" standard USB header. The mainboard end of the WRUSBY33 is a single piece 4 pin connector, vs the individual single pin connectors on the WRUSBY11. The WRUSBY33 has a single connector for +5v, -Data, +Data, and Ground that follows the standard pin out configuration. WRUSBY33 Product Page: https://www.crystalfontz.com/product/wrusby33-2mm-lcd-usb-cable
  Reason:	Based on customer requests and feedback, the WRUSBY33 has a much simpler connection to the main board of a system with a 0.100" standard USB header. The mainboard end of the WRUSBY33 is a single piece 4 pin connector, vs the individual single pin connectors on the WRUSBY11.
  Impact:	The change should have no fit, form, or function change if the system board being used has a standard 0.100" four pin header for USB connectivity that follows the the standard pin out configuration. Semi-Custom, or Defined Part (DP) numbers will not be affected.
