μC/USB Device™ Universal Serial Bus Device Stack
DESCRIPTION
μC/USB Device is a USB device stack designed for embedded
systems equipped with a USB device controller. A hardware
abstraction layer makes it easy to port μC/USB-Device to new USB
controllers by simply modifying existing hardware access routines.
Drivers for several common device classes (Mass Storage, CDC, HID)
are offered, supplemented by a framework for easily developing new
class drivers. The stack can run with or without an RTOS.
μC/USB Device uses a modular architecture with three software
layers between the application and the hardware.

1 Micriμm data sheet for μC/USB Device™ (10/20/10)
Each target requires a Device Controller Driver to interface with
the device controller hardware to process interrupts, notify the
stack core of bus events, and receive and transmit packets.
The Device core controls packet reception and transmission and
responds to standard host requests during enumeration (the
process by which a host discovers the feature of a device).
The target provides its functionality to the host with one or more
class drivers (e.g. the Mass Storage Class driver). Each class
driver responds to class-specific requests and may provide an
API for controlling the feature or receiving and transmitting
information.

Limitation
Speed – Supports full-speed (12 Mbit/sec) and high speed (480
Mbit/sec) controllers. Better transfer rates are available with
high-speed controllers, yet most platforms do not reach
theoretical maximum (approximately 50 Mbytes/sec). A high-
speed
performance increase over a full-speed controller on a
comparable MCU/MPU.
Memory Footprint – μC/USB-Device’s footprint can be scaled to
con- tain only the features required for the application at hand.
Real-Time Kernel Support – μC/USB-Device can be used with or
with- out a Real-Time Kernel.
Start/Test Application – Simple target test applications are
provided for all USB device classes, in all significant
configurations. For bulk, mass storage, and HID classes, simple
Windows applications are included, constituting an end-to-end
demonstration of USB functionality.
