USB-FileSys

Driver-free USB embedded file system (Previously USB-Config)

USB-FileSys is a low cost USB FAT file system. Its memory area is easily accessed by a host controller using SPI commands, and, when plugged into a USB port, simultaneously appears on a PC like a file system on a removable disk.

For low duty configuration and diagnostic applications, USB-FileSys can use its own on-board pre-formatted flash memory area. For large file storage and transfer applications, USB-FileSys can be interfaced to SD™ cards, and integrated circuits with SD™ card interfaces, of up to 1GB.

USB-FileSys uses the Mass Storage Device (MSD) USB profile. It works without drivers on PCs running Windows (ME or later), Mac (OS 9 or later) or Linux (4.0 or later). It is available pre-programmed as a 28-pin DIL package and a 20 pin SSOP package.   It was previously known as USB-Config.
