CFAF320240F-035T

This is a 320xRGBx240, 3.5 inch diagonal, full-color QVGA graphic TFT display module. Several interfaces such as SPI, and 18/16/9/8 bit parallel, allow compatibility with many different microcontroller configurations. It has an integrated SSD2119 or compatible display controller. The white LED backlight has anode and cathode pins brought out on the FPC connector. The 50 pin FPC mates with standard 0.5mm ZIF sockets such as HFJ150CT-ND and HFK150CT-ND, both readily available from Digi-Key.

Part Change Notice #10403

Products Affected:	CFAF320240F-035T, CFAF320240F-035T-TS, CFAF320240F-035T-CB, CFAF320240F-035T-TS-CB
Date Issued:	February 24, 2012
Summary:	Glass characteristics change requiring single command initialization change for optimal contrast.
Description:	PCN for CFAF320240F family of products due to a change in panel vendors.
Reason:	In order to maintain uninterrupted supply of this module, we changed vendors for the LCD panel so that lead times would not be affected.
Impact:	Because of the slightly different characteristics of the panel, a single command in the initialization of the module should be changed so that optimal contrast can be achieved. No other changes are necessary.
Recommendation:	Change the following registers from: write_command(0x001E); // Power Control 5 write_data(0x00B7); // Page 53 of SSD2119 datasheet to write_command(0x001E); // Power Control 5 write_data(0x00BE); // Page 53 of SSD2119 datasheet and contrast should be optimal for the display.
Availability:	Immediately for non-touchscreen modules, with a cut-in for the modules with a touchscreen over the next several months.
Price Change:	Pricing is not affected by this change.

Tech Bulletin #10335

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.
