USB-FileSys
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.
