S-Touch ™ series STMPE811QTR Alternative

We have checked the specifications for STMicroelectronics’ obsolete STMPE811QTR and suggest the below alternative and comparison between both.

There may be a suitable alternative to the discontinued item STMPE811QTR of the
S-Touch ™ series, so long as you use a SPI interface and not the original device’s I²C.

The manufacturer is unable to supply this device any longer. If it is urgently needed for an ongoing project, TI’s TSC2008IRGVR is a similar alternative. Please check the comparison table shown below - differences between the two ICs are bolded.
