'''NG286LX-12''' was a {{arch|16}} [[system on chip]] designed by [[AMD]] and introduced in late 1990. This chip, which incorporated the {{amd|N80C286-12}} core operating at 12 MHz integrated with all the other components typically found on an IBM PC AT motherboard (e.g. [[Interrupt Controller]], [[Clock Generator]], [[Bus Controller]],  and [[DMA Controller]]). This model is an enhanced version of the {{\\|NG286ZX-12}} which added a few more power saving features.
