Which touch screen controller can replace STMPE811QTR

[June Zhou]

Our device always use your STM32F413ZG and STMPE811QTR – Resistive touch screen controller, but recently, we found ST only produce one touch screen controller currently, the FTG2-SLP. I do not know you will no longer offer STMPE811QTR or temporarily stop producing it?

if you do not provide STMPE811QTR, do you think we can use FTG2-SLP? Is FTG2-SLP the same as STMPE811QTR, specially do they have the similar firmware (I2C bus, registers data, x,y positioning, calibration and registers data)?

if FTG2-SLP is not good for replacing, could you give us some suggestion which other touch screen controller is the best one to replace STMPE811QTR

Thanks.

The STMPE811 has unfortunately been discontinued without replacement for a long time, you can find more information e.g. in this thread.

The FTG2-SLP is a completely different component (not resistive, but capacitive touch screen controller) and not a direct replacement for the STMPE811 .

There used to be an SX8651 from Semtech that was a similar type to the STMPE811, required different driver software, but has probably also disappeared from the market.

We are very sorry, but we cannot recommend a replacement type.

If the problem is solved, please mark this thread as answered by selecting Select as best, as also explained here. This will help other users find that answer faster.
