Product Descriptions

The Am186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 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 requirements 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.
