Green 16x2 Character I2C LCD Display
Part Number: CFA533-YYH-KC
I2C LCD With Keypad – Dark On Yellow-Green
The CFA533-***-KC series is a 16x2 I2C LCD with keypad. The I2C interface allows you to use just two lines (SDA & SCL) to have bi-directional communication with the I2C LCD. Other devices can also share those two I2C control lines with the LCD. Only 4 wires are needed to connect this I2C LCD: power, ground, SDA (I2C Serial DAta) and SCL (I2C Serial CLock).
The CFA533 can run on 3.3v to 5.0v directly, with no changes needed, so you do not need to do any level translation between your embedded processor and the I2C LCD. Simply power the CFA533 from the same supply as your processor and the I2C signal levels will match up.
Using only one address on your I2C bus, you can add all the elements that you need for your front panel. The CFA533 I2C LCD can also read up to 32 DS18B20 digital temperature sensors, giving you an easy way to integrate temperature sensing over the I2C bus. No additional firmware or pins are needed on the host system.
This CFA533-YYH variant shows crisp, dark letters against a yellow-green backlit background. The keypad is backlight in a matching yellow-green. Since the LCD is a backlit positive STN, the CFA533-YYH I2C LCD is easily viewable in all lighting conditions, from direct sunlight to a completely dark room.

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. |
Part Change Notice #10351: CFA533 family hardware revision v1.1
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-YYH-KI, CFA533-TFH-KU, CFA533-TFH-KS, CFA533-TFH-KL, CFA533-TFH-KC |
Date Issued: | August 2, 2011 |
Summary: | CFA533 family hardware revision v1.1 |
Last revision: | v1.0 |
Description: | The CFA533 v1.1 hardware changes are as follows:
|
Reason: | As part of our continuous improvement process, the CFA533 family is being revised to hardware v1.1. This was done based on customer feedback to improve the functionality and appearance of the CFA533 family. |
Impact: | Hardware v1.1 should be a drop in replacement for most applications. No form or fit changes have been implemented. The exception may be with the YYH variants. Due to the increased number of yellow-green LEDs in the LCD backlight, the current profile of these variants has increased. |
Recommendation: | Participate in discounted pricing for first run CFA533 v1.1 hardware based modules through September 30, 2011. |
Availability: |
|
Price Change: | No price change is scheduled at this time. Pricing will be reviewed Q1 2012. |
