FEATURES
16x2 LCD has a large display area in a compact 108 mm x 43 mm (4.25" x 1.69") package.
Large, easy-to-read characters: 7.3 mm (0.287") character height.
19200/9600/4800/2400 baud RS-232 interface.
CFA632 is available in three popular choices.
CFA632-NFA-KS
Reflective, no backlight.
FSTN positive mode LCD (displays dark characters on light background—needs ambient light to be visible).
Sunlight readable.
CFA632-YFB-KS
Yellow-green array LED backlit with FSTN positive mode LCD (displays dark characters on light background).
Sunlight readable.
CFA632-YMC-KS
Yellow-green array LED backlit with STN blue negative mode LCD (displays illuminated yellow-green
characters on dark background).
Modules are thin:
CFA632-NFA (reflective) is 15.9 mm (0.626") including DB9 connector.
CFA632-YFB-KS and CFA632-YMC-KS (LED backlit) are 19.9 mm (0.783") including DB9 connector.
Software controlled contrast.
The CGROM is an enhanced version with many useful characters: numeric superscripts, icons, mathematical sym-
bols, some fractions, a great variety of arrows, many currency symbols, and more.
LCD characters are contiguous horizontally to allow the host software to display “gapless” bar graphs in horizontal
direction.
Software controlled terminal style automatic scrolling and line wrapping.
Unique scrolling marquee feature continuously scrolls a message across the display without host intervention.
Low speed "SPI" (F
clk max
= 18 KHz) and "Inverted TTL" RS-232 for embedded applications.
Buffered communication.
Single board construction—no connectors to fail.
Optional 5.25" half-height drive-bay
CFA632 Serial / USB LCD Mounting Bracket
available.
Nonvolatile memory capability (EEPROM) to customize the “power-on” display settings. 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.
Extended voltage (9-15 volts) and 5 volts power inputs standard on all modules for the controller. Backlight is 5 volts
only.
DB9 connector provided for simple RS-232 hookup.
Low power: non-backlight operation will self-power from the DTR and RTS lines of most serial ports.
RoHS compliant.
