Description

CFA-632 USB LCD 16x2, Yellow/Green LED Backlight, FSTN Positive, Transflective 0°C to +50°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 #10579: Reverted the SPI functionality to Crystalfontz CFA632 legacy implementation.

Products Affected: CFA632-YMC-KS, CFA632-NFA-KS, CFA632-YFB-KU, CFA632-YMC-KU, CFA632-NFA-KU, CFA632-NFG-KS, CFA632-YFH-KS, CFA632-YDI-KS, CFA632-NFG-KU, CFA632-YFH-KU, CFA632-YDI-KU, CFA632-YDI-KL, CFA632-YDI-KN, CFA632-YDI-KC, CFA632-YDI-KP, CFA632-YFH-KL, CFA632-YFH-KN, CFA632-YFH-KC, CFA632-YFH-KP
Date Issued: December 20, 2013
Summary: Reverted the SPI functionality to Crystalfontz CFA632 legacy implementation.
Last revision: v3.2.5
Description: Reverted the SPI functionality to Crystalfontz CFA632 legacy implementation where the SPI_BUSY line is used as a busy indicator instead of the module's unused transmit line. Firmware will migrate from v3.2.5 to v3.2.6
Reason: To maintain legacy functionality.
Impact: Impact to customers utilizing SPI functionality only.
Recommendation: For questions please contact Technical Service at 1-888-206-9720.

Part Change Notice #10307: Update CFA632 series to firmware v2.2 and wide temperature LCD.

Products Affected: CFA632-YMC-KS, CFA632-NFA-KS, CFA632-YFB-KU, CFA632-YMC-KU, CFA632-NFA-KU, CFA632-NFG-KS, CFA632-YFH-KS, CFA632-YDI-KS, CFA632-NFG-KU, CFA632-YFH-KU, CFA632-YDI-KU
Date Issued: January 10, 2011
Summary: 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:
  1. Wide temperature support with -20°C to +70°C operation / -30°C to +80°C storage

  2. 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.

  3. 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.

  4. 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.
Availability: Volume availability Second Quarter 2011.
Price Change: No price change at this time
