GENERAL DESCRIPTION
The Am186TMEM/EMLV and Am188TMEM/EMLV microcontrollers are the ideal upgrade for 80C186/188 and 80L186/188 microcontroller designs requiring 80C186/ 188 and 80L186/188 microcontroller compatibility, increased performance, serial communications, and a direct bus interface. The Am186EM/EMLV and Am188EM/EMLV microcontrollers increase the performance of existing 80C186/188 and 80L186/188 systems while decreasing their cost. The Am186EM/EMLV and Am188EM/EMLV microcontrollers are part of the AMD E86 family of embedded microcontrollers and microprocessors based on the x86 architecture. The E86 family includes the 16- and 32-bit microcontrollers and microprocessors described on page 8 The Am186EM/EMLV and Am188EM/EMLV microcontrollers integrate the functions of the CPU, nonmultiplexed address bus, timers, chip selects, interrupt controller, DMA controller, PSRAM controller, asynchronous serial port, synchronous serial interface, and programmable I/O (PIO) pins on one chip. Compared to the 80C186/188 and 80L186/188 microcontrollers, the Am186EM/EMLV and Am188EM/EMLV microcontrollers enable designers to reduce the size, power consumption, and cost of embedded systems, while increasing functionality and performance. The Am186EM/EMLV and Am188EM/EMLV microcontrollers have been designed to meet the most common requirements of embedded products developed for the office automation, mass storage, communications, and general embedded markets. Specific applications include disk drives, hand-held terminals and desktop terminals, fax machines, printers, photocopiers, feature phones, cellular phones, PBXs, multiplexers, modems, and industrial controls.
