FM3580
5-Bit VID Controller with PC Security Element
General Description
The FM3580 is an standard 5-bit VID controller with an integrated
a Security controller. FM3580 extends the typical VID feature to a
PC motherboard by offering a security function which deters
cloning of PC motherboards.
FM3580’s Security block generates a new pseudo-random code
each time one of its internal registers is read. The PC BIOS is
programmed to poll pseudo-random code from the FM3580 at
frequent intervals. If the appropriate code is not read, the system
shuts down, or refuses to boot at power-up. The VID controller
portion of FM3580 is identical to FM3560 and is pin compatible
with FM3560.
FM3580 is designed using low power CMOS technology.
