GENERAL DESCRIPTION
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.
This document contains information on a product under development at Advanced Micro Devices. The information
is intended to help you evaluate this product. AMD reserves the right to change or discontinue work on this proposed
product without notice.

connects to the data inputs and outputs, and the chip
selects connect to the memory chip-select inputs.
The RD output connects to the SRAM Output Enable
(OE) pin for read operations. Write operations use the
byte-write enables connected to the SRAM Write
Enable (WE) pins.
The example design uses 2-Mbit memory technology
(256 Kbytes) to fully populate the available address
space. Two flash PROM devices provide 512 Kbytes of
nonvolatile program storage, and two static RAM
devices provide 512 Kbytes of data storage area.
COMPARING THE ES TO THE 80C186
Figure 1 shows an example system using a 40-MHz
Am186ES microcontroller. Figure 2 shows a
comparable system implementation with an 80C186.
Because of its superior integration, the Am186ES
microcontroller system does not require the support
devices that are required on the 80C186 example
system. In addition, the Am186ES microcontroller
provides significantly better performance with its 40-
MHz clock rate.

COMPARING THE ES TO THE EMTABLE1
Compared to the Am186EM and Am188EM
microcontrollers, the Am186ES and Am188ES
microcontrollers have the following additional features:
n Two full-featured asynchronous serial ports
n The ability to use DMA to and from the serial ports
n Two additional external interrupt signals
n Enhancements to the watchdog timer to improve its
security and functionality
n A pulse width demodulation option
n A data strobe bus interface option for DEN
n ARDY functionality is changed to allow both edges
of ARDY to be asynchronous to the clock
n An option to have all MCS space asserted through
MCS0
n On the Am186ES microcontroller, static bus sizing
allows UCS space to use a 16-bit data bus, while
LCS space can be either 8-bit or 16-bit. All non-
UCS and non-LCS memory and I/O accesses can
be 8-bit or 16-bit. This capability is available only on
the Am186ES microcontroller; the Am188ES micro-
controller has a uniform 8-bit access width.
n The synchronous serial interface is removed
n On the ES, row addresses are not driven on DRAM
refreshes
Two Asynchronous Serial Ports
The Am186ES and Am188ES microcontrollers have
two identical asynchronous serial ports. Each serial
