Summary: Technical Bulletin TB01: Comparison of CFA533 and CFA633 Modules by Version Number
Description: The attached PDF file describes differences between our CFA633 v1.5x and CFA633 v2.0 intelligent display module series. We also list the CFA533 series as a comparison for customers who do not require the fan control available in the CFA633 series. Hardware version numbers are silkscreened on the back of the PCBs.

Date Issued: October 6, 2010
Summary: CFA633 hardware v2.0 / Firmware version 2.0 (called "s2.0" for serial modules and "u2.0" for USB modules)
Last revision: Hardware v1.5c / Firmware v1.9k
Description: In a continuation of product improvement the CFA633 will be moving to a new hardware layout with supporting firmware changes and improvements. Highlights include:
  • Serial and USB interfaces are build options - no more USB daughter board

  • Wide temperature support with -20°C ~ +70°C operation / -30°C ~ +80°C storage

  • Taller keypad
Reason: Improvements in design allow for better manufacturing, ESD protection, and appearance.
Impact: The new version is designed to be Fit, Form, and Function compatible with previous versions of the CFA633 series. Semi-Custom and Defined Parts will be migrated to new part numbers.
Recommendation: Engineering samples should be available by the end of Quarter 4, 2010. Please send an email to support@crystalfontz.com to work with our engineering and support team to assist you with the migration.
Availability: Volume availability First Quarter 2011
Price Change: No change at this time

Date Issued: August 12, 2010
Summary: We will be phasing in the CFA-633 hardware version v1.5c over the next few months as the inventory of v1.5a modules is exhausted.
Last revision: 1.5a
Description: The currently shipping version of the CFA-633 hardware is v1.5a.

Here is a list of the changes between v1.5a and v1.5c:

* Changed from black painted steel plated bezel to stainless steel bezel. Your front panel bezel should hide the bezel, so this change should not affect the appearance of your product. If your product design exposes part of the CFA-633's black bezel, that area will now show as stainless steel.
* Increased keep-out clearance on PCB around the mounting holes.
* Minor PCB layout changes.
* Some factory configuration jumpers have changed.

Please see the document linked here for photographs showing the difference:
CFA633_v1-5a_to_v1-5c_changes.pdf
Impact: The v1.5c should be a drop-in replacement for any v1.5a application.
Recommendation: If you currently have a semi-custom part number based on v1.5a, we will need to issue a new semi-custom part number based on the v1.5c platform.
Availability: 0-2 months

Date Issued: June 6, 2010
Summary: Keypad height change
Description: Over the next 6 months or so, we will be transitioning to a keypad that is 1.5mm taller than the keypad currently shipping on these modules.
Reason: We have found that in all cases that we are aware of, the keypad being 1.5mm taller will alleviate some customer difficulties.
Recommendation: If you need the keypad to remain the same height for your application, please email support@crystalfontz.com so that we can set aside some of the shorter keypads for your company's application.
Availability: ~0-6 months.
Price Change: None.
