How to Design an Embedded System with USB Flash Drive Support
The removable USB flash drive is a key technology in the embedded computing world. Among other things, it can be used to store and transfer logged data, back up a device’s settings, or be a vehicle to update a deployed device’s firmware. When you need to transfer data from an embedded system to a PC (or vice versa), using a portable memory device, like a USB flash drive, is a convenient method, especially when transferring data over a network is not possible or desirable.
Although USB flash drives are easy to use, designing an embedded system that supports the use of these devices can be a challenging task.
Memory experts Datakey have produced a 17-page free white paper which gives an overview of USB and highlights several USB host design options that will support the use of a USB flash drive. The paper discusses some of the design considerations for the USB connectors, power supplies and PCB. It is full of links to helpful resources to make sure your embedded system design will successfully communicate with USB flash drives so that they can be used for a host of applications.
