[EOL] Six Interface 16x2 Character LCD

Part Number: CFA632-NFG-KS

CFA-632 Serial LCD 16x2, RoHS Compliant, No Backlight, FSTN Positive, Reflective -20°C to +70°C 6:00

The CFA632 can use any of SIX interfaces on any modules in the family by simply changing the interface selection using a command setting and making the appropriate jumper configurations. The interfaces are:

Large easy-to-read LCD in a compact size can display 16 characters x 2 lines. Overall module size is 108.00 mm width x 42.00 mm height x 19.90 mm depth (4.25" x 1.65" x 0.78"). Character height is 7.30 mm (0.29").

Optional PC CDROM mounting bracket with three choices of overlay for a single bay is available. Mounting dimensions are 5.25" (W) x 1" (H).

The CFA632 family has two colors choices:

  1. CFA632-YDI-Kx: Yellow-green array LED backlight with negative FFSTN transmissive mode LCD. Displays yellow-green characters on a dark (near-black) background. The display can be read in normal office lighting and in dark areas. May be difficult to read in direct sunlight.
  2. CFA632-YFH-Kx: Yellow-green array LED backlight with positive FSTN transflective mode LCD. Displays dark(near-black) characters on yellow-green background. The display can be read in normal office lighting, in dark areas, and in bright sunlight.

Use any of six interfaces on any module in the CFA632 family by simply changing the interface selection in a command and using the appropriate jumper configurations.

The displays have a 6 o’clock viewing angle (polarizer viewing direction)

Adjustable contrast. The module’s default contrast value will be acceptable for many applications. If necessary, you can adjust the contrast by using control command.

The modules have a RockWorks RW1067 controller.

.

Extended voltage (9-15 volts for interfaces using DB9 connector) and 5 volts power inputs standard for the controller. Backlight is 5 volts only.

Use the nonvolatile memory capability (EEPROM) to customize the “power-on” display settings.

Wide temperature range for operation is -20°C to +70°C.

RoHS compliant. You can download the Certificate of Compliance for ISO, RoHS, and REACH from the Doc/Files tab on the part number’s website page.

    Part Change Notice #10453: New v3.2 firmware to support CFA632 hardware v3.3 family of module
    Products Affected: CFA632-NFG-KS, CFA632-YFH-KS, CFA632-YDI-KS, CFA632-NFG-KU, CFA632-YFH-KU, CFA632-YDI-KU
    Date Issued: February 5, 2013
    Summary: New v3.2 firmware to support CFA632 hardware v3.3 family of module
    Last revision: FW v2.4
    Description: As part of our continuous improvement process, the CFA632 family of modules has been redesigned to fall more in line with our other Value Add families of intelligent modules.

    The new firmware for the CFA632 family of modules will retain the same stream based command structure.

    Changes:
    Control the Boot Screen – Ctrl+I (\009)
    This command has increased functionality to include, but not limited to;
    - Interface selection
    - Baud rate
    - Data normal / inverted
    - Splash screen

    Separate USB and Serial interface builds to support the on-board USB interface design.


    With the change from Samsung S6A0073 to Rockworks RW1067, the following commands and functionality are depreciated:

    + Show inverted blinking block cursor – Ctrl+G (\007)
    + Set Scrolling Marquee Characters - Ctrl+U (\021)
    + Enable Scrolling Marquee - Ctrl+V (\022)

    * Specifications are subject to change
    Reason: The firmware has been revised to support the hardware changes from the Samsung S6A0073 LCD controller to the Rockworks RW1067, and the Holtek HT48R30 one-time-programmable controller being replaced with the Cypress PSoC CY8C27443 for improved functionality
    Impact: This new firmware version has changes and depreciated commands and functionality.
    Recommendation: Engineering samples should be available Quarter 3, 2013. Please send an email to support@crystalfontz.com to work with our engineering and support team to assist you with the migration.
    Availability: Q3 2013 - Samples available
    End of Q3 / Beginning Q4 2013 - Transition to new version when previous version is exhausted
    Q1 2014 - All CFA632 shipments new hardware
    Price Change: We are anticipating an increase in pricing.
    New pricing is TBD.
