Optimized for Power and Performance
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.
Add Hi-Speed USB 2.0 to Your Device
The NET2272 can be used to easily add a USB 2.0 peripheral port to any local bus
based embedded system. The local bus interface of the NET2272 can often connect

gluelessly because
its interface looks
like an 8 or 16-bit
SRAM. Most
CPUs and DSPs
already have these
memory interfaces
integrated.
The NET2272’s
asynchronous bus
makes it frequency
independent.
Accessing the
NET2272’s
registers is as
simple as accessing
memory.
