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
