KEY FEATURES AND BENEFITS

The Am186ED/EDLV microcontrollers extend the AMD

family of microcontrollers based on the industry-stan-

dard x86 architecture. The Am186ED/EDLV microcon-

trollers are a higher-performance, highly integrated

version of the 80C186/188 microprocessors, offering

an attractive migration path. In addition, the Am186ED/

EDLV microcontrollers offer application-specific fea-

tures that can enhance the system functionality of the

Am186ES/ESLV and Am188ES/ESLV microcontrol-

lers. Upgrading to the Am186ED/EDLV microcontrol-

lers is an attractive solution for several reasons:

n Programmable DRAM controller—Enables sys-

tem designers to take advantage of low-cost DRAM

and fully utilize the performance and flexibility of the

x86 architecture. The DRAM controller supports

zero wait-state performance with 50-ns DRAM at 40

MHz, or, if required, can be programmed with wait

states. The Am186ED/EDLV microcontrollers pro-

vide a CAS-before-RAS refresh unit.

n Minimized total system cost—New and en-

hanced peripherals and on-chip system interface

logic on the Am186ED/EDLV microcontrollers re-

duce the cost of existing 80C186/188 designs.

n X86 software compatibility—80C186/188-com-

patible and upward-compatible with the other mem-

bers of the AMD E86 family.
