Am186

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

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

DISTINCTIVE CHARACTERISTICS

GENERAL DESCRIPTION

T h e A m 1 8 6 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

ar e p ar t o f th e A MD E 8 6 fa mi l y o f em be dd e d

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.

E86

compatible microcontrollers with enhanced bus

interface

— Lower system cost with higher performance

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

High performance

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

— Supports zero-wait-state operation at 25 MHz

access and remove the requirement for a 2x clock

input

— Nonmultiplexed address bus

— Processor operates at the clock input frequency

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

Enhanced integrated peripherals provide

increased functionality, while reducing system

cost

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

— Two full-featured asynchronous serial ports allow

— Serial port hardware handshaking with CTS,

with 100-ns static memory (Am186ESLV and

Am188ESLV microcontrollers) and 40 MHz with

70-ns static memory (Am186ES and Am188ES

microcontrollers)

16-bit memory and I/O static bus option

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

RTS, ENRX, and RTR selectable for each port
