Wireless USB Device Controller
HCL has developed the Device controller for wireless USB which converts the wired USB2.0 device packets to wireless packets based on WUSB specification Rev1.0 thereby maintaining the backward compatibility .It also supports the standard MAC-PHY interface .
Its basic functional block includes - protocol adaptation layer, AES 128-CCM encryption and decryption logic and supports the distributed reservation protocol mentioned by the WUSB standards.
HCLT WUSB Device Controller has been built on the Wired USB 2.0 protocol, so it can work seamlessly with Device Controllers designed for USB 2.0.
It supports an AMBA Interface on the device Controller side which is used for configuration of registers and for converting AMBA packets into USB 2.0 protocol. The Device Controller supports standard UWB PHY Interface on the PHY end.
