USB LCD Displays
16x2 Character Display Module
Part Number: CFA533-TFH-KU
The CFA-533 is an intelligent 16x2 character USB LCD with a keypad. The USB interface allows you to easily connect the CFA-533 LCD to your host device using a USB cable. You can change the text displayed on the LCD, and read the keypad through the USB. The USB interface is implemented using a genuine FTDI FT232RL USB UART with rock-solid WHQL signed Windows drivers and is fully supported under Linux. The LCD's USB interface is exposed as a COM port, new software is easy to write and legacy applications are easy to support.
This CFA533-TFH variant features crisp, dark letters against a white, backlit background. The keypad has a matching white LED backlight. Since the LCD is a backlit positive FSTN, the CFA533-TFH USB LCD is readable in direct sunlight, as well as complete darkness.
The CFA-533 solves your entire front panel requirements in one simple, proven device. The 2x16 LCD display allows showing critical error or status messages, and the keypad can be used to interact with the user, all over the single USB connection. The CFA-533 USB display fits easily in the front panel of a 1U appliance.
The CFA-533 USB LCD can also reset your system as well as power it on and off using its ATX power supply control functionality. This way the CFA-533 can replace the ubiquitous power and reset switches while cleaning up the front panel design and simplifying your BOM and assembly.
With the CFA-533 USB LCD, you also get the great (and free) support that Crystalfontz is known for.

Part Change Notice #10725: CFA533 serial and USB firmware revision 1.1 to 1.2
| Products Affected: | CFA533-YYH-KS, CFA533-TMI-KS, CFA533-TMI-KU, CFA533-YYH-KL, CFA533-TMI-KL, CFA533-TFH-KU, CFA533-TFH-KS, CFA533-TFH-KL |
| Date Issued: | July 8, 2016 |
| Summary: | CFA533 serial and USB firmware revision 1.1 to 1.2 |
| Last revision: | 1.1 |
| Description: | The CFA533 series of advanced display modules will be changing from the current serial and USB firmware version 1.1 to version 1.2. Firmware changes support hardware design changes; no functional changes were made or added. Firmware version 1.2 requires Hardware version 1.4 or newer. |
| Reason: | As part of our continuous improvement, firmware has been updated for use with updated hardware for the CFA533 series of advanced display modules. |
| Impact: | Command 1 (0x01): Get Hardware & Firmware Version This command will now report the following strings Serial versions (-KL and -KS suffix): "CFA533:h1.4,s1v2" USB version (-KU suffix): "CFA533:h1.4,u1v2" |
| Recommendation: | CFA533 firmware version 1.2 is considered a fit and form replacement. Testing of new firmware is recommended when the new hardware version 1.4 is available |
| Availability: | CFA533 hardware version 1.4 should begin shipping Q4 2016. Engineering samples for testing / validation of the firmware version 1.2 will be available during this same time frame. |
| Price Change: | No price change is currently scheduled. |
Part Change Notice #10724: CFA533 series Hardware revision 1.1 to 1.4
| Products Affected: | CFA533-YYH-KS, CFA533-YYH-KU, CFA533-TMI-KS, CFA533-TMI-KU, CFA533-YYH-KL, CFA533-TMI-KL, CFA533-YYH-KC, CFA533-TMI-KC, CFA533-TFH-KU, CFA533-TFH-KS, CFA533-TFH-KL, CFA533-TFH-KC |
| Date Issued: | July 8, 2016 |
| Summary: | CFA533 series Hardware revision 1.1 to 1.4 |
| Last revision: | 1.1 |
| Description: | The CFA533 series of advanced display modules will be changing from the current hardware version 1.1 to version 1.4. Design changes were made for backwards compatibility. Hardware version 1.4 requires firmware version 1.2 or newer. |
| Reason: | As part of our continuous improvement, design changes have been made to the hardware of the CFA533 series of advanced display modules for improved manufacturability, improved quality, and a lower current profile. |
| Impact: | Factory default configuration has no functional changes. Standard and custom configurations are not affected by the new hardware layout. CFA533 hardware version 1.4 should replace the previous version of the CFA533 with no physical changes and is considered a fit and form replacement. Six 0 ohm resistors have been added as factory default for closing the following jumpers: JPGPIO1 -> RJPGPIO1 JPUSBPWR -> RJPUSBPWR JP2 -> RJP2 JP4 -> RJP4 JP6 -> RJP6 JP8 -> RJP8 Solder jumpers are still in place for configuration after jumper resistor removed. Jumpers will appear open. Configuration changes not performed by Crystalfontz America, Inc. will need to make note of this manufacturing change. |
| Recommendation: | CFA533 hardware version 1.4 is considered a fit and form replacement. Testing of new hardware is recommended when available. |
| Availability: | CFA533 hardware version 1.4 should begin shipping Q4 2016. Engineering samples for testing / validation will be available during this same time frame. |
| Price Change: | No price change is currently scheduled. |

| Date Issued: | July 1, 2015 |
| Summary: | Deprecation of "Drive Bay Kit Configurator" / New part numbers for drive bay kits. |
| 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. |
