The USB5537B-5000AKZE is a 7-port SS/HS USB Hub Controller with the USB 3.0 Specification. It supports 5Gbps SuperSpeed (SS), 480Mbps Hi-Speed (HS), 12Mbps Full-Speed (FS) and 1.5Mbps Low-Speed (LS) USB signalling for complete coverage of all defined USB operating speeds. It supports legacy USB speeds through its USB 2.0 hub controller. The new SuperSpeed hub controller (available on 4 of the 7 ports) operates in parallel with the USB 2.0 controller, so the 5Gbps SuperSpeed data transfers are not affected by the slower USB 2.0 traffic. It supports battery charging on a per port basis. On battery charging enabled ports, the devices provide automatic USB data line handshaking. The handshaking supports USB 1.2 Charging Downstream Port (CDP), Dedicated Charging Port (DCP) and legacy devices. The controller is configured for operation through internal default settings, where custom configurations are supported through an on-chip OTP ROM, an external SPI ROM or SMBus.
