Am286ZX/LX was a family of system on chips based on the Am286 (80286) architecture designed by AMD and introduced in late 1990. These chips integrated the CMOS core from the Am286 family along with all the logic functions found in the original IBM PC-AT motherboard. These chips provided a clear advantage for mobile devices and laptops by providing lower-power, smaller space, and higher performance at a cheaper price.

History[edit]
By 1990 just over 2.2 million laptops/notebooks were sold and they were projecting that number to increase to 4.6 by 1993.[1]. In an attempt to reduce power consumption and reduce the overall size of mobile devices AMD introduced the AMD286ZX/LX family of SoCs 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 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.
Members[edit]
AMD offered two slightly different versions: Am286ZX and Am286LX.
Am286ZX[edit]
The Am286ZX offered the base features, which is the entire SoC with all of its basic functions.

Am286LX[edit]
The Am286LX chips offered everything found in the Am286ZX but included a number of other power saving features such as CPU shutdown mode, system shutdown mode, staggered DRAM refresh, and slow-refresh DRAM support
