CFA533-TMI-KC, CFA533-TMI-KC 16x2 I2C Serial Character LCD Display Module with keypad a

CFA533-TMI-KC

The CFA533-TMI-KC is truly an embedded interface solution, not just an LCD module. Designed to fit in a 1U server enclosure, it is by no means confined to one. This display can be used to drive LEDs using the GPIOs provided, can be used as the interface to configure headless servers, or as a wired remote from your home theater PC with the right software.

The CFA-533 series has four directional buttons, an enter (check) key, and cancel ('x') key. Instead of using a corruptible stream-based communication protocol, it uses a 16-bit CRC protected packet-based protocol to communicate with its host, meaning that line noise, environmental interference, etc., won't cause the display to start a critical and unprepared process without being initiated by the user. With the included backlight for the keypad and for the LCD, you can use this display in low-light conditions.

The CFA-533 series is backward compatible with the CFA-633 series for its communication interface, but has added features such as 3.3v to 5v operating range, ability to change the brightness of the keypad backlight separate from the LCD backlight, stainless steel bezel, and uses a single supply voltage for both logic and backlighting. Voltage compensated single-supply 3.3v to 5.5v operation allows the CFA-533 to easily work with a wide variety of power supplies. The CFA-533 series is the logical progression for any application already using the CFA-633 series, but not utilizing the fan functionality. The CFA-533 is perfect to be the display component and user interface for your next project requiring an LCD and keypad but no fan control functionality.

We provide a Windows compatible test / demonstration program and source that works with TotalPhase Aardvark I2C adapters.

Compact and fully integrated user interface for "Communication Appliance" applications
Wide power supply voltage range (VDD = +3.3v to +5.0v) is perfect for embedded systems.
The contrast and backlights are fully compensated over the supply voltage range. No adjustments are needed to be made to the contrast setting or backlight brightness over the full range of power supply input voltage.
Only a single supply is needed.
LED backlit STN 16x2 LCD
Integrated LED backlit 6-button translucent silicon keypad with screened legend
RS-232 serial, 0-5v serial, or USB interface versions available
Robust packet based communications protocol with 16-bit CRC
Compact size: fits in a 1U rack mount case (35mm overall height)
ATX power supply control functionality allows the buttons on the CFA-533 to replace the "power" and "reset" buttons on your system, simplifying your front panel design
Temperature monitoring: up to 32 channels at up to 0.5 deg C absolute accuracy. Ready-to-use WRDOWY17 Dallas Semiconductor 1-Wire temperature sensors are optional. Alternatively, you can create your own sensors using DS1822 or DS18B20 parts and the tutorial on creating temperature sensors. (Specify when ordering)
Non-volatile memory ("EEPROM") capability: Customize the "power-on" display settings plus a 16-byte "scratch" register for storing IP, netmask, system serial number, etc.

Date Issued:	June 6, 2010
Summary:	Keypad height change
Description:	Over the next 6 months or so, we will be transitioning to a keypad that is 1.5mm taller than the keypad currently shipping on these modules.
Reason:	We have found that in all cases that we are aware of, the keypad being 1.5mm taller will alleviate some customer difficulties.
Recommendation:	If you need the keypad to remain the same height for your application, please email support@crystalfontz.com so that we can set aside some of the shorter keypads for your company's application.
Availability:	~0-6 months.
Price Change:	None.

Summary:	Change in CFA-533 I2C part number.
Description:	CFA533-TMI-KI changed to CFA533-TMI-KC CFA533-YYH-KI changed to CFA533-YYH-KC
Reason:	KI as a suffix indicating I2C was sometimes confused with KL. We will now use KC as a suffix to indicate I2C
Impact:	Part number change only.
Recommendation:	Please update your part numbers for I2C parts as follows: CFA533-TMI-KI is now CFA533-TMI-KC CFA533-YYH-KI is now CFA533-YYH-KC
Availability:	No change to availability.
