  Part Change Notice #10454: New v3.1 hardware version for CFA634 family of modules.

  Products Affected:	CFA634-NFA-KS, CFA634-TFB-KS, CFA634-NFA-KU, CFA634-TFB-KU, CFA634-NFG-KS, CFA634-TFH-KS, CFA634-TMI-KS, CFA634-YFH-KS, CFA634-YDI-KS, CFA634-NFG-KU, CFA634-TFH-KU, CFA634-TMI-KU, CFA634-YFH-KU, CFA634-YDI-KU
  Date Issued:	February 6, 2013
  Summary:	New v3.1 hardware version for CFA634 family of modules.
  Last revision:	HW v2.4
  Description:	As part of our continuous improvement process, the CFA634 family of modules has been redesigned to fall more in line with our other Value Add families of intelligent modules. The module is keeping the same dimensions, mounting points, and existing header locations. Changes: - LCD controller is changing from Samsung S6A0073 to Rockworks RW1067 - Holtek HT48R30 is being replaced by Cypress PSoC CY8C27443 - USB interface integrated on PCB using FTDI FT232RL - PCB layout changed to accommodate new LCD controller, new microcontroller, integrated USB interfaces - The following hardware functionality has been migrated to firmware control; - - Interface selection - - Data normal / Inverted - - Splash screen control - - Baud rate * Specifications are subject to change
  Reason:	Samsung S6A0073 LCD controller is EOL. Module has been redesigned to incorporate the Rockworks RW1067. The Holtek HT48R30 one-time-programmable controller replaced with the Cypress PSoC CY8C27443 for improved functionality.
  Impact:	This new hardware version is designed to be as fit and form compatible as possible with the current shipping hardware. There are major changes to the PCB layout due to the re-design of the CFA634 family. Existing header locations and mounting points are renaming the same. Additional header locations have been added for programming the PSoC and future functionality.
  Recommendation:	Engineering samples should be available Quarter 3, 2013. Please send an email to support@crystalfontz.com to work with our engineering and support team to assist you with the migration.
  Availability:	Q3 2013 - Samples available End of Q3 / Beginning Q4 2013 - Transition to new version when previous version is exhausted Q1 2014 - All CFA634 shipments new hardware
  Price Change:	We are anticipating an increase in pricing. New pricing is TBD

  Part Change Notice #10308: Update CFA634 series to firmware v2.3 and wide temperature LCD.

  Products Affected:	CFA634-YMC-KS, CFA634-NFA-KS, CFA634-TFB-KS, CFA634-TMC-KS, CFA634-YFB-KU, CFA634-YMC-KU, CFA634-NFA-KU, CFA634-TFB-KU, CFA634-TMC-KU, CFA634-NFG-KS, CFA634-TFH-KS, CFA634-TMI-KS, CFA634-YFH-KS, CFA634-YDI-KS, CFA634-NFG-KU, CFA634-TFH-KU, CFA634-TMI-KU, CFA634-YFH-KU, CFA634-YDI-KU
  Date Issued:	January 10, 2011
  Summary:	Update CFA634 series to firmware v2.3 and wide temperature LCD.
  Last revision:	Hardware v2.3, Firmware v2.0
  Description:	In a continuation of product improvement the CFA634 series has the following improvements: Wide temperature support with -20°C to +70°C operation / -30°C to +80°C storage The bezel changed from black painted metal to stainless steel. Stainless steel has lower environmental impact and improves ESD protection. If your design has the bezel exposed, it will show the silver color of the stainless steel rather than the previous painted black bezel. The previous CFA634-YMC-KS and CFA634-YMC-KU (new CFA634-YDI-KS and CFA634-YDI-KU) changed from STN to double negative (FFSTN) LCD for improved appearance. Firmware revision to match hardware revision and is now displayed on the boot screen
  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 CFA634 series. Semi-Custom and Defined Parts will have updated part numbers.
  Recommendation:	Engineering samples should be available by the end of Quarter 1, 2011. 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 Second Quarter 2011.
  Price Change:	No price change at this time
