11. ElectroStatic Discharge (ESD)
11.1 ESD protection
The pins that are connected to the USB connector (DP, DM, V_BUS and GND) have a
minimum of ±4 kV ESD protection. Capacitors 0.1 µF and 1 µF must be connected in
parallel from V_BUS to GND to achieve this ±4 kV ESD protection (see Figure 20).
Remark: Capacitors 0.1 µF and 1 µF are also required by Universal Serial Bus
Specification Rev. 2.0. For details on the requirements for C_VBUS, see Section 16.
