STOTG04E Electrical characteristics
7/26
(1) Transmitting and receiving at 12Mbit/s, loads of 50pF on D+ and D- pins, no capacitive loads on VP and VM pins
(2) Not tested in production; characterization only
(3) Except D+ pin in the I2C mode where this pin is open-drain with internal pull-up resistor
(4) See paragraph 6.7.1
