CFA634 Family

The CFA634 can use any of SIX interfaces on any modules in the family by simply changing the interface selection using a command setting and making the appropriate jumper configurations. The interfaces are:

  • USB
  • RS232
  • Logic Level Serial
  • Logic Level Serial inverted
  • I2C
  • SPI

  2. CFA634-TMI-Kx: White edge-lit LED backlight with negative STN transmissive mode LCD. Displays light (nearwhite) characters on a blue background. The display can be read in normal office lighting and in dark areas. Maybe difficult to read in direct sunlight.
  3. CFA634-YDI-Kx: Yellow-green array LED backlight with negative FFSTN transmissive mode LCD. Displays yellow-green characters on a dark (near-black) background. The display can be read in normal office lighting and in dark areas. May be difficult to read in direct sunlight.
  4. CFA634-YFH-Kx: Yellow-green array LED backlight with positive FSTN transflective mode LCD. Displays dark (near-black) characters on yellow-green background. The display can be read in normal office lighting, in dark areas, and in bright sunlight.
  • Large easy-to-read LCD in a compact size can display 20 characters x 4 lines. Overall module size is 130.00 mm, width x 63.00 mm height x 19.90 mm depth (5.12" x 2.48" x 0.78"). Character height is 7.30 mm (0.29").
  • Attractive stainless steel bezel.
  • Optional PC CDROM mounting bracket with three choices of overlay to fit two 5.25" wide bays is available.
  • The displays have a 6 o’clock viewing angle (polarizer viewing direction).
  • Adjustable contrast. The module’s default contrast value will be acceptable for many applications. If necessary, you can adjust the contrast by using control function.
  • The modules have a RockWorks RW1067 controller.
  • Robust packet based communications protocol with 16-bit CRC.
  • Extended voltage (9-15 volts for interfaces using DB9 connector) and 5 volts power inputs standard for the controller.
  • Backlight is 5 volts only.
  • Use the nonvolatile memory capability (EEPROM) to customize the “power-on” display settings.
  • Wide temperature range for operation is -20°C to +70°C.
  • RoHS compliant. You can download the Certificate of Compliance for ISO, RoHS, and REACH from the Doc/Files tab on the part number’s website page.

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 deprecated:

+ 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.

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.

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 -20C to +70C operation / -30C to +80C 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.
