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.
