Publication# 20002 Rev: B Amendment/0 Issue Date: February 1997 Am186TMES/ESLV and Am188TM ES/ESLV High Performance, 80C186-/80C188-Compatible and 80L186-/80L188-Compatible, 16-Bit Embedded Microcontrollers DISTINCTIVE CHARACTERISTICS n E86™ family 80C186-/188- and 80L186-/188- compatible microcontrollers with enhanced bus interface — Lower system cost with higher performance — 3.3-V ±0.3-V operation (Am186ESLV and Am188ESLV microcontrollers) n High performance — 20-, 25-, 33-, and 40-MHz operating frequencies — Supports zero-wait-state operation at 25 MHz with 100-ns static memory (Am186ESLV and Am188ESLV microcontrollers) and 40 MHz with 70-ns static memory (Am186ES and Am188ES microcontrollers) — 1-Mbyte memory address space — 64-Kbyte I/O space n Enhanced features provide improved memory access and remove the requirement for a 2x clock input — Nonmultiplexed address bus — Processor operates at the clock input frequency — On the Am186ES/ESLV microcontroller, 8-bit or 16-bit memory and I/O static bus option n Enhanced integrated peripherals provide increased functionality, while reducing system cost — Thirty-two programmable I/O (PIO) pins — Two full-featured asynchronous serial ports allow full-duplex, 7-bit, 8-bit, or 9-bit data transfers — Serial port hardware handshaking with CTS, RTS, ENRX, and RTR selectable for each port — Multidrop 9-bit serial port protocol — Independent serial port baud rate generators — DMA to and from the serial ports — Watchdog timer can generate NMI or reset — A pulse-width demodulation option — A data strobe, true asynchronous bus interface option included for DEN — Pseudo static RAM (PSRAM) controller includes auto refresh capability — Reset configuration register n Familiar 80C186/80L186 peripherals — Two independent DMA channels — Programmable interrupt controller with up to eight external and eight internal interrupts — Three programmable 16-bit timers — Programmable memory and peripheral chip-select logic — Programmable wait state generator — Power-save clock divider n Software-compatible with the 80C186/80L186 and 80C188/80L188 microcontrollers with widely available native development tools, applications, and system software n A compatible evolution of the Am186™EM and Am188 ™EM microcontrollers n Available in the following packages: — 100-pin, thin quad flat pack (TQFP) — 100-pin, plastic quad flat pack (PQFP) GENERAL DESCRIPTION T h e Am18 6 ™ES/ESLV and Am188™ES/ESLV microcontrollers are an ideal upgrade for 80C186/188 and 80L186/188 microcontroller designs requiring 80C186/188 and 80L186/188 compatibility, increased performance, serial communications, and a direct bus interface. The Am186ES/ESLV and Am188ES/ESLV microcontrollers ar e p a r t o f th e A M D E 8 6 fa mi l y o f em be dd e d microcontrollers and microprocessors based on the x86 architecture. The E86 family includes the 16- and 32-bit microcontrollers and microprocessors described on page 8. T he Am186 ES/ESL V and Am18 8ES/ESL V microcontrollers have been designed to meet the most co mm on r e qu ir em en ts o f em be dd ed p r od uct s developed for the office automation, mass storage, and communications markets. Specific applications include disk drives, hand-held and desktop terminals, set-top controllers, fax machines, printers, photocopiers, feature phones, cellular phones, PBXs, multiplexers, modems, and industrial controls. |
