CFA-634 USB LCD 20x4, White Edge LED Backlight, STN Negative, Blue, Transmissive -20°C to +70°C, 6:00

CFA634 USB Family

Full 634 v2.0 feature set: This USB version retains the entire feature set of the original 634 v2.0:

  • The LCD material for the positive displays is FSTN (Film compensated Super Twisted Nematic) instead of STN. FSTN gives better contrast, faster response and makes an all-around more readable display.
  • The display as the ability to store a customized boot screen of your design in its EEPROM. All features of the display are controlled: characters displayed, user-definable characters, backlight setting, contrast setting, cursor position, cursor style, "wrap" setting, "scroll" setting, and even the scrolling marquee.
  • The CGROM is an enhanced version with many more useful characters: numeric superscripts, icons, mathematical symbols, some fractions, a great variety of arrows, many currency symbols, and more.
  • Large, easy to read characters: 7.3mm (0.287") character height
  • Available with bright, even, software adjustable LED backlighting or in a low-power reflective model
  • Software controlled contrast
  • "Gapless" horizontal bargraphs
  • Software controlled terminal style automatic scrolling and line wrapping
  • Unique "Scrolling Marquee" feature continuously scrolls a message across the display without host intervention.
  • Buffered communication
  • Large display area in a compact 130mm x 63mm (5.12" x 2.48")package
  • Thin:
    • Reflective is 15.9mm (0.626") including DB-9 connector
    • LED Backlit is 19.9mm (0.783") including DB-9 connector
    The USB converter board and its compact connector does not add to the overall thickness of the module.
  • Negative voltage for contrast generated on board
  • Available in a LCD drive bay kit, (see mounting bracket photos)
  • Available with serial interface
For its USB connection, this module uses a non-standard 2mm low profile connector. USB cables with this type of connector are not readily available at retail, so if you do not have this type of cable and cannot build one, please choose to add one of our USB cables with the proper connector below. Without a cable, you will not be able to use this module or connect it to your host system.

Please make sure to order either a WRUSBY03 cable or a WRUSBY33 cable with a module of this type.
For reference only. For design purposes, please use the specifications in the datasheet.

Date Issued: February 6, 2013
Summary: New v3.1 firmware to support CFA634 hardware v3.1 family of module
Last revision: FW 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 new firmware for the CFA634 family of modules will retain the same stream based command structure.

Changes:
Control the Boot Screen – Ctrl+I (\009)
This command has increased functionality to include, but not limited to;
- Interface selection
- Baud rate
- Data normal / inverted
- Splash screen

Separate USB and Serial interface builds to support the on-board USB interface design.


With the change from Samsung S6A0073 to Rockworks RW1067, the following commands and functionality are depreciated:

+ Show inverted blinking block cursor – Ctrl+G (\007)
+ Set Scrolling Marquee Characters - Ctrl+U (\021)
+ Enable Scrolling Marquee - Ctrl+V (\022)

* Specifications are subject to change as


Reason: The firmware has been revised to support the hardware changes from the Samsung S6A0073 LCD controller to the Rockworks RW1067, and the Holtek HT48R30 one-time-programmable controller being replaced with the Cypress PSoC CY8C27443 for improved functionality.
Impact: This new firmware version has changes and depreciated commands and 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.

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

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:
  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.
    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.
