GENERAL DESCRIPTION
T h e A m 1 8 6 ™ES/ESLV and Am188™ES /ESLV microcontrollers are an ideal upgrade for 80C186/188 and 80L186/188 microcontroller designs requiring 80C186/188 and 80L186/188 compatibility, increased performance, serial communications, and a direct bus interface. The Am186ES/ESLV and Am188ES/ESLV microcontrollers ar e p ar t o f th e A MD E 8 6 fa mi l y o f em be dd e d microcontrollers and microprocessors based on the x86 architecture. The E86 family includes the 16- and 32-bit microcontrollers and microprocessors described on page 8. The Am186ES/ESLV and Am188ES/ESLV microcontrollers have been designed to meet the most c om mo n r eq ui r e me nt s of e mb ed de d pr o du c ts developed for the office automation, mass storage, and communications markets. Specific applications include disk drives, hand-held and desktop terminals, set-top controllers, fax machines, printers, photocopiers, feature phones, cellular phones, PBXs, multiplexers, modems, and industrial controls.
