exist. The customers can select any one of them during the mass production stage, making
production much easier. With these flexibilities, the manufacturers can easily build
different products by using exactly the same components. The only place needs to be
changed on PCB is pin 35.
The USB Mass Storage Class compliance capability of SN11087 makes it a truly
“plug-and-play” device without vendor drivers under Windows 2000/ME/XP and Mac OS
9/10. SN11087 also provides PC boot up and data security function that exact the same as a
floppy disk (1.44M), which makes it an ideal replacement for the legacy floppy disk.
