7. Electrical Characteristics
7.1 I/Os DC Characteristics Referred to HVCC
Notes: 1. A 220nF ceramic capacitor is connected between the pin HVCC and the pin GND and closest to HVCC pin.
2. RPU1 Pull Up resistor is as per the ECN “Pull-up/pull-down resistors” published by the USB-IF. RPU1 value is betw een 900Ω
and 1575Ω when the bus is idle and between 1425Ω and 3090Ω when the upstream device is transmitting
3. RPU2 Pull Up resistor is as per the IC_USB1.0 published by the USB-IF. RPU2 value is between 1kΩ and 3kΩ to attach and
between 30kΩ and 150kΩ during idle.
7.2 I/Os DC Characteristics Referred to PVCC
Notes: 1. A 220nF ceramic capacitor is connected between the pin PVCC and the pin GND and closest to PVCC pin.
