The ADLLX8PC uses an AMD LX8 Geode processor, which operates at a 500MHz clock frequency, but BIOS settings on this board allow the CPU frequency to be set as low as 300MHz. This option can also be hard-wired into the board as a special factory modification. Please contact your sales rep for details.
Although we occasionally receive requests for CPUs with slower 66MHz clock speeds, many of these older processors are not supported by our chip vendors anymore, so as a result, we do not currently offer any 66MHz or 133MHz processors to replace these legacy PC/104 systems. ADL Embedded Solutions remains committed to helping developers create new designs using modern processors that are faster, more reliable, and use less power.
