Hi,

What is the value of the internal pull-up or pull-down resistor connected to the SDHN, STB, and TXD pins?

Best Regards,

Hi Nishie,

It ensure the input pins are not floating and keeps the device in a lower power mode by default, thanks.

Best Regards,

Michael.

Hi Michael-san,

Thank you for your support.

I am sorry that my English is insufficient.

I would like to know the specification (xOhm) of built-in resistance value, not the role of resistance.

Best Regards,

Nishie

Hi Nishie-san,

This may be estimated using their respective IIL spec (R = V / IIL). I.e., TXD -200 to 20 uA implies 18k to 180k ohms, STB -20 to 2 uA estimates 180k to 1.8M ohms and SHDN -2 to 2 uA estimates 1.8 M ohms, thanks.

Best Regards,

Michael.
