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:
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.
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.
X86 software compatibility—80C186/188-com-
patible and upward-compatible with the other mem-
bers of the AMD E86 family.
