Voltage of I2C

Hello forum,

I am new here, and it is my first project using a Dialog component. I am using the model SLG46826, but we will not be able to program the chip and then solder it to the PCB.

Searching, I found the In-circuit programming device (still not sure about its part numer, if it is SLG4DVKGSD or SLG4DVKISP), and important information such as it´s connection and voltage for the I2C. It would help a lot if I had in hands its datasheet.

See.. I am worried because my main MCU it's connected also to the I2C, and it will damage when voltage is more than 3.6V.

Can someone help me to confirm: (1) the correct part number for the In-circuit programming device?
(2) Voltage range of I2C connection?

提前谢谢!

Hello Rafaela,

Thanks for reaching out to us.

SLG46826 is the GPAK part with In-System Programmability, hence you will be able to program the part after soldering. SLG4DVKGSD is the part number for the Serial Debugger board (http://www.silego.com/buy/index.php?main_page=product_info&cPath=66_74&products_id=727) which used to be previously SLG4DVKISP. Please find attached a datasheet for the 46826 part. Also since the I2C line voltage is common for every device, even if the device is supplied with a different voltage, the I2C line voltage remains the same.

Hope this helps. Please let me know if you have further questions

Kind Regards

Shivani

Hi Shivani, thanks for the help with issue (1).

Item (2) I wish to know the voltage of I2C from the side of SLG4DVKGSD.. maybe a datasheet or schematics of this part would help. Its possible to have those information?
