PRELIMINARY

Am186 ED/EDLV

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

16-Bit Embedded Microcontrollers

DISTINCTIVE CHARACTERISTICS

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

– Serial port hardware handshaking with CTS,

microcontroller with enhanced bus interface

RTS, ENRX, and RTR selectable for each port

– Lower system cost with higher performance

– 3.3-V ± 0.3-V operation (Am186EDLV

microcontrollers)

– Improved serial port operation enhances 9-bit

DMA support

– Independent serial port baud rate generators

– DMA to and from the serial ports

n Programmable DRAM Controller

– Supports zero-wait-state operation with 50-ns

DRAM at 40 MHz, 60-ns @ 33 MHz, 70-ns @ 25

MHz

– Includes programmable CAS-before-RAS

refresh capability

– Watchdog timer can generate NMI or reset

– A pulse-width demodulation option

access and remove the requirement for a 2x clock

input

– Nonmultiplexed address bus

– Processor operates at the clock input frequency

– 8-bit or 16-bit programmable bus sizing including

8-bit boot option

n Software-compatible with the 80C186 and

80C188 microcontrollers with widely available

native development tools, applications, and

system software

n Enhanced integrated peripherals

n A compatible evolution of the Am186EM,

– 32 programmable I/O (PIO) pins

Am186ES, and Am186ER microcontrollers

– Two full-featured asynchronous serial ports allow

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

n Available in the following packages:

– 100-pin, thin quad flat pack (TQFP)

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

GENERAL DESCRIPTION

The Am186^TMED/EDLV microcontrollers are part of the

AMD E86^TMfamily of embedded microcontrollers and mi-

croprocessors based on the x86 architecture. The

Am186ED/EDLV microcontrollers are the ideal upgrade

for 80C186/188 designs requiring 80C186/188 compat-

ibility, increased performance, serial communications, a

direct bus interface, and more than 64K of memory.

sizing, and programmable I/O (PIO) pins on one chip.

Compared to the 80C186/188 microcontrollers, the

Am186ED/EDLV microcontrollers enable designers to

reduce the size, power consumption, and cost of em-

bedded systems, while increasing reliability, functional-

ity, and performance.

The Am186ED/EDLV 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

PBXs, multiplexers, modems, disk drives, hand-held

and desktop terminals, fax machines, printers,

photocopiers, and industrial controls.

The Am186ED/EDLV microcontrollers integrate a com-

plete DRAM controller to take advantage of low DRAM

costs. This reduces memory subsystem costs while

maintaining SRAM performance.The Am186ED/EDLV

microcontrollers also integrate the functions of a CPU,

nonmultiplexed address bus, three timers, watchdog

timer, chip selects, interrupt controller, two DMA control-

lers, two asynchronous serial ports, programmable bus
