The OXCFU950 is a low-cost, synchronous 16-bit PC Card (PCMCIA) or CompactFlash/CF+ to UART and USB host controller. It combines the high performance of Oxford Semiconductor OX16C95x UART technology with USB host capabilities. The inclusion of both a UART and USB make the OXCFU950 ideal for wireless data cards. The OXCFU950 integrates an OHCI-based USB host controller, which supports a single USB port via the integrated transceiver. An 8-Kbyte memory provides an efficient interface for buffer and control structures between the USB controller and the device driver. The attribute memory, UART and USB registers can be programmed via the internal EEPROM during power up or hard/soft reset, allowing different card manufacturers to customize information contained in the attribute memory or UART/USB registers, for example PC Card ID value.
