High Performance, 80C186-/80C188-Compatible and

80L186-/80L188-Compatible, 16-Bit Embedded Microcontrollers

DISTINCTIVE CHARACTERISTICS

n E86 family 80C186-/188- and 80L186-/188-

compatible microcontrollers with enhanced bus

interface

— Multidrop 9-bit serial port protocol

— Independent serial port baud rate generators

— DMA to and from the serial ports

— Lower system cost with higher performance

— Watchdog timer can generate NMI or reset

— A pulse-width demodulation option

— 3.3-V ±0.3-V operation (Am186ESLV and

Am188ESLV microcontrollers)

— A data strobe, true asynchronous bus interface

option included for DEN

n High performance

— 20-, 25-, 33-, and 40-MHz operating frequencies

— Pseudo static RAM (PSRAM) controller includes

auto refresh capability

— Supports zero-wait-state operation at 25 MHz

with 100-ns static memory (Am186ESLV and

Am188ESLV microcontrollers) and 40 MHz with

70-ns static memory (Am186ES and Am188ES

microcontrollers)

— Reset configuration register

n Familiar 80C186/80L186 peripherals

— Two independent DMA channels

— Programmable interrupt controller with up to

eight external and eight internal interrupts

— 1-Mbyte memory address space

— 64-Kbyte I/O space

— Three programmable 16-bit timers

n Enhanced features provide improved memory

access and remove the requirement for a 2x clock

input

— Programmable memory and peripheral

chip-select logic

— Programmable wait state generator

— Power-save clock divider

— Nonmultiplexed address bus

— Processor operates at the clock input frequency

n Software-compatible with the 80C186/80L186

and 80C188/80L188 microcontrollers with widely

available native development tools,

— On the Am186ES/ESLV microcontroller, 8-bit or

16-bit memory and I/O static bus option

n Enhanced integrated peripherals provide

increased functionality, while reducing system

cost

applications, and system software

n A compatible evolution of the Am186 EM and

Am188 EM microcontrollers

— Thirty-two programmable I/O (PIO) pins

n Available in the following packages:

— 100-pin, thin quad flat pack (TQFP)

— 100-pin, plastic quad flat pack (PQFP)

— Two full-featured asynchronous serial ports allow

full-duplex, 7-bit, 8-bit, or 9-bit data transfers

— Serial port hardware handshaking with CTS,

RTS, ENRX, and RTR selectable for each port

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 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.

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.

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.
