型號： EV-TD122-UHC124-PCI

類別： 集成電路

描述： The EV‐TD122‐UHC124‐PCI evaluation board is a system for TD122 and UHC124 customer evaluations and internal software development in the PC environment. The evaluation board allows the user to install and use the TD122 or UHC124 in any PCI based computer. Application software running on the system has access to the TD122 or UHC124 via the PCI memory space. The evaluation board can be used without the PCI bridge board, the PCI104. The evaluation board is a two board combination (An EV‐TD122‐UHC124 evaluation board with 2 or 4 USB host ports and A 33MHz, 32bit PCI bridge board, the PCI104). The PCI104 bridge board contains the PCI9030 PCI bridge chip that bridges the PCI bus to the TD122 or UHC124. Power and control signals to the PCI bus are maintained by the PCI bridge chip, while initialization and configuration of the PCI bridge chip is maintained by the on board serial EEPROM. . High performance USB host controller with 4 ports and integrated analog transceivers . Supports USB Specification 2.0 compliant full speed (12Mb/s) and low speed (1.5Mb/s) USB devices . Standard 8bit microprocessor bus interface. 2Kbyte data memory . Supports all four types of USB transfers . Supports batch processing of up to 16 USB transactions without generating an MCU interrupt . Supports double buffering for all USB transfers . Hardware generated start of frame (SOF) . 6MHz crystal/oscillator to reduce cost and EMI . Single 3.3V power supply . Power management with host suspend, remote wakeup, and power saving modes
