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:
  1. Wide temperature support with -20°C to +70°C operation / -30°C to +80°C storage

  2. 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.

  3. 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.

  4. 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.
