GENERAL DESCRIPTION
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, w a t c h d o g t i m e r, a s y n c h r o n o u s s e r i a l p o r t , synchronous serial interface, and programmable I/O © Copyright 2000 Advanced Micro Devices, Inc. All rights reserved. D R A T F (PIO) pins on one chip. Compared to the 80C186/ 8 0 C 1 8 8 m i c r o c o n t r o l l e r s, t h e A m 1 8 6 E R a n d 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 ter minals, fax machines, printers, photocopiers, and industrial controls.
