GENERAL DESCRIPTION
The Am186äES/ESLV and Am188äES/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 are part of the AMD E86 family of embedded 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 common requi rements of embedded products 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.
