1. USB MSD Reference Design Hardware Overview — Silicon Laboratories AN282|
Among the USB device classes natively supported by popular operating systems, the USB Mass Storage Device (MSD) class is one of the most widely supported device classes.
A USB device that supports this class can use the built-in drivers provided by the operating system, without the need to install or maintain any custom device drivers.
The USB MSD Reference Design utilizes this widespread support by providing device firmware for Silicon Laboratories USB microcontrollers that complies with the MSD class specification.
This USB MSD Reference Design Programmer's Guide describes in detail the various components of the device firmware. The USB-MSD-RD Reference Design Kit User's Guide includes demonstration instructions and information about the kit contents.
The MSD reference design hardware consists of two boards — C8051F340-TB Target Board and CF, SD, MMC Memory Expansion Board (AB5). These are contained in the kits C8051F340DK and USB-MSD-RD, respectively.
See the USB-MSD-RD User's Guide for details on the contents of these kits. Figure 1 shows these two boards connected via the expansion connector. Figure 2 shows a block diagram with the connections between the hardware components.
Refer to the USB-MSD-RD User's Guide for detailed pin connections, schematic, and bill of materials of the evaluation board. 22 pages.
