AM186ED 16-Bit Embedded Microcontrollers

The Am186TMED/EDLV microcontrollers are part of the AMD E86TM family of embedded microcontrollers and microprocessors based on the x86 architecture. The Am186ED/EDLV microcontrollers are the ideal upgrade for 80C186/188 designs requiring 80C186/188 compatibility, increased performance, serial commu.
