FSTN (Film compensated Super Twisted Nematic) LCD glass on on NFG and YFB models. FSTN gives better contrast, faster response, and makes an all-around more readable display than STN.
FFSTN (Fast Film compensated Super Twisted Nematic) LCD glass on YDI models. The double film gives superior contrast and brightness when compared to STN or FSTN glass.
Bright, even, software-adjustable LED backlight on YFB and YDI models.
Low-power reflective polarizer on NFG models.
The display has the ability to store a customized boot screen of your design in its EEPROM. All features of the display are controlled: characters displayed, user-definable characters, backlight setting, contrast setting, cursor position, cursor style, "wrap" setting, "scroll" setting, and even the scrolling marquee.
Terminal style automatic scrolling and line wrapping, controlled in software. Unique "Scrolling Marquee" feature continuously scrolls a message across the display without host intervention.
Enhanced CGROM version with many useful characters: numeric superscripts, icons, mathematical symbols, some fractions, a great variety of arrows, many currency symbols, and more.
The processor's reset circuit can handle a wide range of slow-turn-on power supply conditions.
Negative voltage for contrast generated on board.
Extended voltage (9-15v) and 5v power inputs standard on all modules for this controller. Backlight (on models other than NFG) is 5v only.
Optional 1" x 5.25" drive bay bracket with choice of attractive overlays. See Kit Configurator.
Large, easy-to-read characters are 7.3 mm (0.287") high
Large display area in a compact 108 mm x 42 mm (4.25" x 1.65") package.
Thin: Depth of 15.9 mm (0.626") on non-backlit models (NFG), and 19.9 mm (0.783") on others.
Wide temperature (except YFB)
Stainless steel bezel (except black painted metal on YFB)
"Gapless" horizontal bar graphs.
Buffered communication.
Single board construction. No connectors to fail.
RoHS compliant.
Other Features:
Supports 19200, 9600, 4800 and 2400 baud rates.
DB9 connector provided for simple RS-232 hookup.
Low speed "SPI" (Fclk max=18KHz) and "Inverted TTL" RS-232 for embedded applications.
Low power: Non-backlight operation will self-power from the DTR and RTS lines of most serial ports.
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 accomodate 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:
Engineering samples should be available by the end of Quarter 1, 2011. Please send an email to support@crystalfontz.com to work with our engineering and support team to assist you with the migration.
Availability:
Volume availability Second Quarter 2011.
Price Change:
The CFA632 series has incurred a slight pricing increase.
Tech Bulletin #10310
New Product:
CFA632-NFG-KS
Date Issued:
January 11, 2011
Summary:
New Product in Intelligent Serial LCD Modules: CFA632-NFG-KS
Description:
CFA-632 Serial LCD 16x2, RoHS Compliant, No Backlight, FSTN Positive, Reflective -20°C to +70°C 6:00
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. Please send an email to support@crystalfontz.com to work with our engineering and support team to assist you with the migration.
