Am186 and Am188

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

16-Bit Embedded Microcontrollers with RAM

— DMA to and from asynchronous serial port

DISTINCTIVE CHARACTERISTICS

— Synchronous serial interface allows half-duplex,

bidirectional data transfer to and from ASICs

n E86^TMfamily 80C186- and 80C188-compatible

microcontrollers with enhanced bus interface

— Reset configuration register

— Additional external interrupts

— Lower system cost with high performance

— 3.3-V ± 0.3-V operation with 5-V tolerant I/O

n Memory integration

— Hardware watchdog timer can generate NMI or

system reset

— 32 Kbyte of internal SRAM

— Pseudo static RAM (PSRAM) controller includes

auto refresh capability

— Internal SRAM provides same performance as

zero-wait-state external memory

n Familiar 80C186 peripherals with enhanced

n High performance

functionality

— 25-, 33-, 40- and 50-MHz operating frequencies

with 55-ns external memory

— Programmable interrupt controller with six

external interrupts

— 1-Mbyte memory address space

— 64-Kbyte I/O space

— Three programmable 16-bit timers

— Programmable memory and peripheral

chip-select logic

n Enhanced features provide faster access to

memory and various clock input modes

— Programmable wait state generator

— Power-save clock mode

— Nonmultiplexed address bus provides glueless

interface to external RAM and ROM

n Software-compatible with the 80C186 and

— Phase-locked loop (PLL) enables processor to

operate at up to four times clock input frequency

80C188 microcontrollers

n Widely available native development tools,

n Enhanced integrated peripherals

applications, and system software

— 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)

— Asynchronous serial port allows full-duplex, 7-bit

or 8-bit data transfers

GENERAL DESCRIPTION

The Am186^TMER and Am188^TMER microcontrollers are

part of the AMD E86™ family of embedded

microcontrollers and microprocessors based on the

x86 architecture. The Am186ER and Am188ER

microcontrollers are the ideal upgrade for designs

requiring 80C186/80C188 microcontroller

compatibility, increased performance, serial

communications, a direct bus interface, and integrated

memory.

(PIO) pins on one chip. Compared to the 80C186/

80C188 microcontrollers, the Am186ER and

Am188ER microcontrollers enable designers to reduce

the size, power consumption, and cost of embedded

systems, while increasing functionality and

performance.

The Am186ER and Am188ER microcontrollers have

been designed to meet the most common

requirements of embedded products developed for the

communications, office automation, mass storage, and

general embedded markets. Specific applications

include feature phones, cellular phones, PBXs,

multiplexers, modems, disk drives, hand-held terminals

and desktop terminals, fax machines, printers,

photocopiers, and industrial controls.

The Am186ER and Am188ER microcontrollers

integrate memory and the functions of the CPU,

nonmultiplexed address bus, timers, chip selects,

interrupt controller, DMA controller, PSRAM controller,

watchdog timer, asynchronous serial port,

synchronous serial interface, and programmable I/O
