Dark 16x2 Character USB Display Module
Part Number: CFA632-YDI-KU
16x2 USB character LCD module, Yellow-Green LED Backlight, FFSTN Negative (Black), Transmissive, -20°C to +70°C operation, 6:00 viewing angle.
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").
- The CFA632 can use any of SIX interfaces on any CFA632 module by simply changing the interface selection using a command setting and making the appropriate jumper configurations.
- Optional PC CDROM mounting bracket with overlay for a single bay is available after adding a display module to cart. Mounting dimensions are 5.25" (W) x 1" (H).
- 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.
- 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.

Description: Starting August 1, 2015 the "Drive Bay Kit Configurator" located at https://www.crystalfontz.com/products/select_kit.html will no longer be functional for ordering one of our Serial or USB displays (CFA533, CFA631, CFA632, CFA633, CFA634, CFA635, and CFA735) in a bracket or SLED. This functionality is being moved to the Customize and Add to Cart process when checking out. This will allow for further customization by our customers to better fit their needs.
This change will eliminate the current "kits", but will add options not previously available such as pre-configured ATX functionality, and ALL the currently available interfaces will be orderable in a drive bay bracket or SLED.
The new part numbers will have the bracket / SLED and overlay type as a PREFIX to the configured part number. The choice for bracket / SLED to a display order will be via the cart options. Our CFA835 displays were introduced with these configuration options.
To see how the new options will look, and what the new part numbers will look like, please see one of our CFA835 parts:
https://www.crystalfontz.com/cart/addtocart.php?product_id=2277&qty=1
NOTE: The SLED is only available for the CFA635, CFA735, and CFA835 products.
Reason: As part of our continuous improvement process, we are integrating the ordering of displays in drive bay and SLED kits as part of the display ordering process. Impact: Drive bay kits in their current configuration will no longer be available. Recommendation: Place orders prior to 2015-08-01 for upcoming production needs via our website or by contacting our logistics department via email: sales@crystalfontz.com, or by calling 1-888-206-9720 (International call +1-509-892-1200).
After the 2015-08-01, please contact our engineering department via support@crystalfontz.com to assist you with ordering your bracket / SLED kits.
Availability: Starting 2015-08-01, the bracket and SLED options for our serial and USB display will be part of the ordering process for the displays Price Change: Pricing bracket / SLED configurations will reflect manufacturing costs. - text_snippet

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

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.
