PRELIMINARY

Am186 EM/EMLV and Am188 EM/EMLV

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

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

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

DISTINCTIVE CHARACTERISTICS

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

or 8-bit data transfers

— Synchronous serial interface allows half-duplex,

bidirectional data transfer to and from ASICs

microcontrollers with enhanced bus interface

— Lower system cost with higher performance

— Pseudo static RAM (PSRAM) controller includes

auto refresh capability

— 3.3-V ±.3-V operation (Am186EMLV and

Am188EMLV microcontrollers)

— Reset configuration register

n Familiar 80C186/80L186 peripherals

— Two independent DMA channels

n High performance

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

— Supports zero-wait-state operation at 25 MHz

with 110-ns static memory (Am186^TMEMLV and

Am188^TMEMLV microcontrollers) and 40 MHz

with 70-ns static memory (Am186^TMEM and

Am188^TMEM microcontrollers)

— Programmable interrupt controller with six

external interrupts

— Three programmable 16-bit timers—timer 1 can

be used as a watchdog interrupt timer

— Programmable memory and peripheral

chip-select logic

— 1-Mbyte memory address space

— 64-Kbyte I/O space

— Programmable wait state generator

— Power-save clock divider

n New features provide faster access to memory and

remove the requirement for a 2x clock input

n Software-compatible with the 80C186/80C188

— Nonmultiplexed address bus

and 80L186 /80L188 microcontrollers

— Phase-locked loop (PLL) allows processor to

operate at the clock input frequency

n Widely available native development tools,

applications, and system software

n New integrated peripherals provide increased

n Available in the following packages:

— 100-pin, thin quad flat pack (TQFP)

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

functionality while reducing system cost

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

GENERAL DESCRIPTION

The Am186^TMEM/EMLV and Am188^TMEM/EMLV micro- controller, DMA controller, PSRAM controller, asynchro-

controllers are the ideal upgrade for 80C186/188 and nous serial port, synchronous serial interface, and pro-

80L186/188 microcontroller designs requiring 80C186/ grammable I/O (PIO) pins on one chip. Compared to the

188 and 80L186/188 microcontroller compatibility, in- 80C186/188 and 80L186/188 microcontrollers, the
