UCODE I2C Reference Design

Question asked by Jon Ledwith on Oct 14, 2019

I am looking for a reference design for the UCODE I2C device SL3S4011FHK. I have designed it into a product from the system level but now need to have proper schematic implementation. The areas of concern are the power connections and the I2C interface. The antenna/antenna connections are self explanatory based on the antenna reference design/ App note AN11180. 

 

Is there anyone that has used this device in a design? (silly question)

Do I need a diode from my system power to VDD such that the device will not power my circuitry when being interrogated?

What kind of filtering is recommended on VDD?

 

Any help would be welcome!

 

Thanks.
