176x220 Parallel Color TFT

Part Number: CFAF176220M-T

176xRGBx220 262K full-color graphic TFT module. This 2" diagonal TFT display has an integrated controller, and can take images formatted as 18 (262K color), 16(65K color), 12(4K color) bits per pixel.

  • 176xRGBx220 Full color graphic TFT module
  • Built-in Sitronix ST775R Controller
  • 8-bit parallel interface
  • Wide Temperature Range
  • RoHS Compliant
  • The connector on the CFAF176220U-020T is a flex tail mated with a "COG" (chip on glass) display construction. This style of connector is designed to be soldered directly to corresponding pads on your PCB by using a hot-bar soldering machine. High volume contract manufacturers will be familiar with this type of construction and its assembly methods. There are hot-bar soldering machines made that are designed for prototype, rework or repair work of TAB connections.

Product Update #10335: Change in TFT part numbers

Products Affected: CFAF240320K-T-TS, CFAF176220M-T, CFAF240320E-T, CFAF128160C-T, CFAF240320P-T, CFAF320240F-T, CFAF320240F-T-TS, CFAF240400D-T, CFAF128160C-018T, CFAF176220U-020T, CFAF240400D-030T, CFAF320240F-035T
Date Issued: March 29, 2011
Summary: Change in TFT part numbers
Description: We are changing our TFT part numbers to have them better describe the parts being ordered. The change should be complete for all TFT modules shipping within the next six months.

Part numbers will change as follows:
CFAF128160C-T will change to CFAF128160C-018T
CFAF176220M-T will change to CFAF176220U-020T
CFAF240320E-T will change to CFAF240320H-022T
CFAF240320K-T-TS will change to CFAF240320K-024T-TS
CFAF240320P-T will change to CFAF240320S-032T
CFAF240400D-T will change to CFAF240400D-030T
CFAF320240F-T will change to CFAF320240F-035T
CFAF320240F-T-TS will change to CFAF320240F-035T-TS
Reason: There are many TFT modules with the same logical dimensions (resolution) with considerably different sizes. In order to help ease any confusion, we have decided to add the diagonal dimension to the part number.
Impact: The part number is all that is changing, there are no other changes to the parts, so there should be no significant impact.
Availability: The transition period should be about six months from the date of this bulletin.

Part Change Notice #10020: Part change notification for CFAF176220M-T series of TFT LCD modules

Product Affected: CFAF176220M-T
Date Issued: September 30, 2009
Summary: Part change notification for CFAF176220M-T series of TFT LCD modules
Last revision: 1.0
Description: Revised datasheet, minor changes to non-controller related information.
Reason: Sitronix ST7773 not being used any longer, display is now using an Orise Tech OTM2201A.
Impact: Because of the LCD controller change, a change to the initialization and functional code (write / read code changes, also CGRAM write, etc.) minor changes will be required.

This change is pin-compatible with the previous version of this display, no change to the circuit will be necessary.
Recommendation: Use code found on page as an example for the new controller.
Availability: 2009/09/30
