OPT3101: Handling of unused pins

Hidekazu Someno

Part Number: OPT3101

Hi Team,

How should each pin be handled when the following pins are not used?

(Leaving it open or pull-up to any?)

- GP1(11 pin)

- GP2(12 pin ) - I/O

- /RST_MS(17 pin) - Input

Best regards,

Hi Someno-san,

RST_MS is active low and has no internal pull up so this will need a pull up. GP1 and 2 can be left alone if they are not used.

Best,

Alex

Thank you for your comments.

Do you have any recommended resistance for a pull-up resister on RST_MS pin to IOVDD?

Hi Someno-san,

Anywhere from 4.4k to 8k should work fine.

Best,

Alex
