In an attempt to reduce power consumption and reduce the overall size of mobile devices [[AMD]] introduced the AMD286ZX/LX family of processors which essentially took all the logic functions and glue chips found on the original IBM PC-AT motherboard and incorporated them onto a single chip. The system on a chip used AMD's existing static CMOS core {{amd|Am286#Low-power CMOS models|from the Am286 family}} and incorporated a bus controller, DMA controller, interrupt controller, and clock generator. The chips were 100% compatible with the IBM PC-AT board. |
