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 and 4-wire resistive touch panel. The white LED backlight has the 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. The touch screen FFC/FPC (Flat Flexible Cable / Flexible Printed Circuit) mates with standard 4-position,1.00 mm pitch ZIF (Zero Insertion Force) connectors such as WM3749CT-ND (top contacts) or WM7937CT-ND (bottom contacts), which are available from Digi-Key.
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
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.
The part number is all that is changing, there are no other changes to the parts, so there should be no significant impact.
The transition period should be about six months from the date of this bulletin.
