By integrating USB2.0 host and On-The-Go controllers in a single two-port package, Oxford Semiconductor’s OXU210HP provides portable consumer electronics designers with the means to enhance product connectivity. Operating at up to 480Mbit/s, high-speed USB2.0 delivers a 40x improvement in data rate over full-speed USB2.0. With an optimised host controller and transaction translator, the OXU210HP offers complete backwards compatibility with full-speed (12Mbit/s) and low-speed (1.5Mbit/s) USB devices. Enabling a non-PC product to act as host and sync or transfer files with a high-speed USB peripheral, the OXU210HP also gives the product the ability to act as a peripheral in order to sync with a PC or other host device. Where space is at a premium, the chip’s On-The-Go controller provides both host and peripheral connectivity through a single mini port.

For added system flexibility, the chip offers simultaneous operation of both ports. The OXU210HP is supported with USB device drivers and the Oxford Semiconductor USBLink product suite, which includes USBLink host, peripheral and On-The-Go stacks ported to a wide variety of RTOS. In addition, low-level controller drivers for other native USB stacks, such as Windows and Linux, are available. Providing 16-bit and 32-bit processor interfaces, the OXU210HP is compatible with a wide range of CPUs. The integration of 72Kbytes of SRAM provides data transfer buffer space to help reduce interrupts and minimise CPU overhead. Power management features include multiple clock domains and three power states. Sampling now, the OXU210HP is available in 128-pin LQFP and 84-ball BGA packages and is priced at $5.5 USD in 10K volumes.
