NET2272REV1A-LF Datasheet PDF - Broadcom

●The NET2272REV1A-LF is a local bus to USB 2.0 high-speed Peripheral Controller for low power and high performance applications. The NET2272 is 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 is low power makes this requirement easy to support. Furthermore, the NET2272 is variable I/O voltage (1.8 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 40MBps. 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-bit of the data bus, while the local CPU is connect to the lower 8-bit of the data bus.
