Local Bus to USB 2.0 Hi-Speed Peripheral Controller
Description:
PLX Technology’s NET2272 Local Bus to Hi-Speed USB 2.0 Peripheral Controller is designed for low power and high performance applications.
The NET2272’s low power requirements (186mW active, 8.1µW standby) make it ideal for bus-powered or battery-powered applications. USB bus-powered devices are allowed to draw a maximum 500mA (according to the USB specification) of operating current from the PC through the USB cable. The NET2272’s low power makes this requirement easy to support. Furthermore, the NET2272’s variable I/O voltage (1.8V to 5V) makes it easy to connect to other low power components.
The NET2272 features the highest sustained data transfer speeds on USB – up to 40Mbytes/sec. An optional Split Bus mode allows for simultaneous DMA and CPU access to the NET2272. In this mode, the external DMA controller is connected to upper 8-bits of the data bus, while the local CPU is connect to the lower 8-bits of the data bus. While DMA transactions are taking place, the local CPU can simultaneously access any endpoint buffer not involving the DMA.
The NET2272’s Dynamic Virtual Endpoint Technology™ actualizes the maximum number of endpoints (30) allowed by the USB specification. This feature provides the flexibility for applications to route different data through different endpoints to improve quality of service and ease of design.
