  Part Change Notice #11246: Keypad LED, H1 Header, and Firmware Change

  Product Affected:	CFA835-TML
  Date Issued:	October 4, 2023
  Summary:	Keypad LED, H1 Header, and Firmware Change
  Description:	The keypad LEDs are changing to an alternative LED, H1 is has been changed by the manufacturer, and the FBSCAB header has been changed by the manufacturer. The polarizer is changing due to the manufacturer EOLing the existing material. The firmware is being updated to resolve an issue where packets could be dropped when polled too quickly. There is no visual difference for the LEDs and the headers still function the same. The firmware is changing from f1v6 to f1v7.
  Reason:	We are switching suppliers to improve the manufacturability of the LEDs. Hirose has changed the family of headers that are used on FBSCAB and H1 to address a packing change they made. The firmware change is a bug fix.

  Part Change Notice #11097: Display Controller Change

  Products Affected:	CFA735-TFK-KR, CFA735-TFK-KT, CFA735-TML-KR, CFA735-TML-KT, CFA835-TML, CFA835-TFK
  Date Issued:	August 4, 2021
  Summary:	Display Controller Change
  Description:	The display controller, UC1611, is no longer available in the form of bonding on the PCB which is how Crystalfontz has used it for this design. We are designing a drop-in replacement that uses the UC1611 heat seal package, which will continue to be supported, instead of the PCB bonding package. This component package change requires us to alter the PCB by moving some components around so that the heat seal tool can be used without causing damage to any components. Availability of the current hardware version is very limited due to the ongoing worldwide chip shortage. Contact sales@crystalfontz.com for availability and to stay updated for a more accurate ship date.
  Reason:	UC1611 is no longer supported in the PCB bondable package.
  Availability:	Fourth-quarter of 2021. If you would like samples when it becomes available, please contact sales@crystalfontz.com.
