Part Number: DS15BR401

Hi Team,

We would like to know N/C pins of DS15BR401TSQ(WQFN PKG).

May I connect N/C pins to VDD(3.3V) or GND?

-1,17,18pins are GND

-19,22pins are VDD(3.3V)

I would like to mount DS15BR401TSQ on a board with DS90LV804TSQ layout.

Regards,

Hi Hide,

These pins should float meaning no connection to these pins. Please do not connect N/C to VDD or GND.

Hi Nasser-san,

Thank you for your prompt reply.

Are N/C pins connected to the internal circuit?

(For example, TI test(debug) circuit etc.)

We guess that N/C pins are not connected to the internal circuit so we can connect N/C pins to VDD or GND.

Could you please let us know if my guess is wrong?

Regards,

Hi Hide,

These pins are used during production testing. The product has not been characterized under the conditions you noted. Therefor we do not recommend connecting these pins to VDD or GND.
