Part Number: DS90UB928Q-Q1


DS90UB928Q-Q1, does GPIO support PWM? How much frequency can it reach?

Soc I2C controls 928 through cable, connected to display,

Is that possible? Are there any problems or risks?


  • Hello Neal,

    Yes, this is possible.

    In the 928 datasheet, section "7.6 AC Electrical Characteristics", there is a minimum pulse width requirement for GPIOs, for forward channel and for back channel. Make sure you are meeting that min requirement when configuring your duty cycle.
