Publication# 20732 Rev: D Amendment/0 Issue Date: June 2000 DRAF T Am186 and Am188 High-Performance, 80C186- and 80C188-Compatible, 16-Bit Embedded Microcontrollers with RAM DISTINCTIVE CHARACTERISTICS n E86TM family 80C186- and 80C188-compatible microcontrollers with enhanced bus interface — Lower system cost with high performance —3.3-V ± 0.3-V operation with 5-V tolerant I/O n Memory integration — 32 Kbyte of internal SRAM — Internal SRAM provides same performance as zero-wait-state external memory n High performance — 25-, 33-, 40- and 50-MHz operating frequencies — Supports zero-wait-state operation at 50 MHz with 55-ns external memory — 1-Mbyte memory address space — 64-Kbyte I/O space n Enhanced features provide faster access to memory and various clock input modes — Nonmultiplexed address bus provides glueless interface to external RAM and ROM — Phase-locked loop (PLL) enables processor to operate at up to four times clock input frequency n Enhanced integrated peripherals — Thirty-two programmable I/O (PIO) pins — Asynchronous serial port allows full-duplex, 7-bit or 8-bit data transfers — DMA to and from asynchronous serial port — Synchronous serial interface allows half-duplex, bidirectional data transfer to and from ASICs — Reset configuration register — Additional external interrupts — Hardware watchdog timer can generate NMI or system reset — Pseudo static RAM (PSRAM) controller includes auto refresh capability n Familiar 80C186 peripherals with enhanced functionality — Two independent DMA channels — Programmable interrupt controller with six external interrupts — Three programmable 16-bit timers — Programmable memory and peripheral chip-select logic — Programmable wait state generator — Power-save clock mode n Software-compatible with the 80C186 and 80C188 microcontrollers n Widely available native development tools, applications, and system software n Available in the following packages: — 100-pin, thin quad flat pack (TQFP) — 100-pin, plastic quad flat pack (PQFP) GENERAL DESCRIPTION The Am186TMER and Am188TMER microcontrollers are par t of the A M D E86™ f amil y of embedded microcontrollers and microprocessors based on the x86 architecture. The Am186ER and Am188ER microcontrollers are the ideal upgrade for designs r e q u ir ing 80C 186/ 80C 188 micr oco n tr ol ler co mpa tibi li ty, i n c r ea se d per for m anc e , se r i al communications, a direct bus interface, and integrated memory. 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 hdog tim e r, asynchr o n ous se r i al por t, synchronous serial interface, and programmable I/O (PIO) pins on one chip. Compared to the 80C186/ 80C18 8 mic r ocon tr o lle r s, th e Am1 86ER an d Am188ER microcontrollers enable designers to reduce the size, power consumption, and cost of embedded sy stems , whil e inc r easi ng functional ity and performance. The Am186ER and Am188ER microcontrollers have be en design ed to meet th e m o st co mmon 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.
