Hi,

Thank you for using STMicroelectroinics products and website.

This forum is dedicated to ST7 microcontrollers.

Concerning non microcontroller products (like ST7540, ST7538x, ...), you will get a better support by contacting our technical support :

Hi, I'm using the ST7540 for a little system of 2 computers, after two weeks I finally accomplished read, write, and send information. But one day, the PA (Power amplifier) stop working, so, the control loops start to working and needs more and more voltage and current, I don't know how it damage, but The ST7540 Have two test pin and I want to test it, but there's no word in the datasheet about how work those pins (27 and 28), can you explain me how?.

Thanks a lot. Greetings from Venezuela.
