USB-FileSysTM
Driver-free USB embedded file system (Previously USB-Config)
Summary
USB-FileSys is a low cost USB FAT file system. Its
memory area is 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-chip pre-formatted
8kByte flash memory area. For moderate file storage
and transfer, USB-FileSys can be interfaced to
Microchip 25AA1024 EEPROM for 128kByte storage.
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 1GBbyte.
(Internal and SD options for 28-pin devices only.)
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.
Features
FAT12 / FAT16 file system, no licensing needed
True MSD plug and play, no drivers required
Works with internal flash memory, 25AA1024
external memory (128Kbyte) and SD compatible
cards and integrated circuits up to 1GB.
Partial support for long file names
USB 2.0 compatible
