Description

Oxford Semiconductor’s TDUHC122 is a two-port, single chip USB host controller that is specifically designed for embedded systems, mobile communications, and consumer products. It is a non-PCI controller that supports full speed(12Mb/s) and low-speed (1.5Mb/s) USB devices. Low interrupt rates, low CPU overhead and low software overhead are essential criteria for embedded designs, and the TDUHC122 excels at all three metrics. It can be interfaced to CISC or RISC microprocessors, microcontrollers, or digital signal processors (DSPs) and is ideal for providing USB host functions to a wide range of applications including mobile devices, cell phones, PDAs, point-of-sale systems, test equipment, internet appliances, as well as serving as an interface for USB to Bluetooth controllers.
