About ADUM2250 I2C isolator logic level

Hi there, I have concerns about connecting ADUM2250 with MCU device such as RL78.

In case of Vdd=3.3V for RL78(MCU), ADUM2250 VoL(0.9V) is higher than ViL(0.2*Vsupply,0.66V at 3.3V) for RL78

Please tell me if there are any good solutions to solve this concern?

The block is just following:


Best regards,
