The CFA632 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:
Large easy-to-read LCD in a compact size can display 16 characters x 2 lines. Overall module size is 108.00 mm width x 42.00 mm height x 19.90 mm depth (4.25" x 1.65" x 0.78"). Character height is 7.30 mm (0.29").
Optional PC CDROM mounting bracket with three choices of overlay for a single bay is available. Mounting dimensions are 5.25" (W) x 1" (H).
The CFA632 family has two colors choices:
- CFA632-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.
- CFA632-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.
Use any of six interfaces on any module in the CFA632 family by simply changing the interface selection in a command and using the appropriate jumper configurations.
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 command.
The modules have a RockWorks RW1067 controller.
.
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.

Product Update #10430: Parts bundled with, and options for WRUSBY11 will now be bundled with and have options for WRUSBY33.
Products Affected: CFA635-TFE-KU, CFA635-TMF-KU, CFA635-YYE-KU, CFA633-YYH-KU, CFA633-TMI-KU, CFA632-NFG-KU, CFA632-YFH-KU, CFA632-YDI-KU, CFA633-RDI-KU, CFA633-TFH-KU Date Issued: September 25, 2012 Summary: Parts bundled with, and options for WRUSBY11 will now be bundled with and have options for WRUSBY33. Description: The WRUSBY33 cable is replacing the WRUSBY11 cable as our standard offering for product bundles and cable options for an internal USB connection for our line of intelligent modules.
The WRUSBY11 has four individual connectors for +5v, -Data, +Data, and Ground. WRUSBY11 Product Page: https://www.crystalfontz.com/product/wrusby11-usb-motherboard-cable
Reason
Based on customer requests and feedback, the WRUSBY33 has a much simpler connection to the main board of a system with a 0.100" standard USB header. The mainboard end of the WRUSBY33 is a single piece 4 pin connector, vs the individual single pin connectors on the WRUSBY11.
The WRUSBY33 has a single connector for +5v, -Data, +Data, and Ground that follows the standard pin out configuration. WRUSBY33 Product Page:
https://www.crystalfontz.com/product/wrusby33-2mm-lcd-usb-cableReason: Based on customer requests and feedback, the WRUSBY33 has a much simpler connection to the main board of a system with a 0.100" standard USB header. The mainboard end of the WRUSBY33 is a single piece 4 pin connector, vs the individual single pin connectors on the WRUSBY11. Impact: The change should have no fit, form, or function change if the system board being used has a standard 0.100" four pin header for USB connectivity that follows the the standard pin out configuration.
Semi-Custom, or Defined Part (DP) numbers will not be affected.
Recommendation: Continue to order your parts with internal USB cable as normal.
If you currently use a Semi-Custom, or Defined Part (DP) number and would like to change to the WRUSBY33 for your part, please contact Engineering Services via support@crystalfontz.com and request the change.Availability: The WRUSBY33 will be replacing the WRUSBY11 effective 2012-09-25. Price Change: There is no price change associated with this product update notice. - text_snippet
Part Change Notice #10317: Minor PCB revision to accommodate longer life MLCC capacitors. Hardware and firmware updating to v2.4.
Products Affected: CFA632-NFG-KS, CFA632-YFH-KS, CFA632-YDI-KS, CFA632-NFG-KU, CFA632-YFH-KU, CFA632-YDI-KU Date Issued: February 1, 2011 Summary: Minor PCB revision to accommodate longer life MLCC capacitors. Hardware and firmware updating to v2.4. Last revision: Hardware v2.2, Firmware v2.2 Description: In a continuation of product improvement the CFA632 series has the following improvements:
- PCB changes to accommodate MLCC capacitors. This hardware revision to v2.4 impacts C7, C3, and C4.
- The firmware will be updated to v2.4 to reflect the new hardware version. No other changes to the firmware are being made.
Minor PCB revision to v2.4 to accommodate longer life MLCC capacitors. Firmware will be updated to v2.4 reflect hardware version.Reason: Manufacturing improvements allow for building the CFA632 series with MLCC capacitors. The MLCC have a longer life than the electrolytic capacitors currently being used. Impact: The new version is designed to be Fit, Form, and Function compatible with previous versions of the CFA632 series.
Please see the previous PCN form physical differences from previous versions:

Part Change Notice #10307: Update CFA632 series to firmware v2.2 and wide temperature LCD.
Products Affected: CFA632-YMC-KS, CFA632-NFA-KS, CFA632-YFB-KU, CFA632-YMC-KU, CFA632-NFA-KU, CFA632-NFG-KS, CFA632-YFH-KS, CFA632-YDI-KS, CFA632-NFG-KU, CFA632-YFH-KU, CFA632-YDI-KU Date Issued: January 10, 2011 Summary: Update CFA632 series to firmware v2.2 and wide temperature LCD. Last revision: Hardware v2.2, Firmware v2.0 Description: In a continuation of product improvement the CFA632 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 CFA632-YMC-KS and CFA632-YMC-KU (new CFA632-YDI-KS and CFA632-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 CFA632 series. Semi-Custom and Defined Parts will have updated part numbers. Recommendation: Engineering samples should be available by the end of Quarter 1, 2011.
