3.1 Overview

USB 2.0, also known as hi-speed USB, is an updated version of USB 1.0/1.1 with improved functionality and increased data speeds. USB 2.0 has a 4-wire interface: VBUS for power, D+ and D- for differential data signals, and a ground pin. The pin configuration for USB 2.0 is shown in Figure 3-1 for a Type-A connector. USB 2.0 is able to support Low Speed (1.5Mbps), Full Speed (12Mbps), and High Speed (480Mbps).

USB 2.0 is a common interface still used today across a range of devices and applications. Since the connector is exposed to the outside world, the system is at risk of a high voltage strike. This transient event can cause damage to the downstream components in the system. The following sections discuss the ESD protection requirements and the system-level design for USB 2.0.
