Part Number: DS90UB925Q-Q1

Hi experts,

My customer try to use DS90UB925 (master) and DS90UB926 (Slave).

Can we communicate serial communication between Ser and Des?

Through Master's I2C pins and Slave's I2C pin, they want to control other system (e.g. touch panel. LED)

Is it possible?

Thanks and best regards,

Ryo Akashi

Hi Akashi,

yes, the functions listed above can be done by UB925/926.

Regarding the I2C operation, I2C master is linked with 925, and can control the I2C slave (such as touch controller) linked to UB926. This is called as remote I2C control. For details, pls refer to below app. note.
