80C186 Microprocessors

Tekmos has developed an 80C186 core design that can be used to replace many variations of the 80C186 microprocessors. The TK80C186EB / TK80C188EB, which replaces the Intel 80C186EB / 80C188EB microprocessors, is available now. The 80C186XL / 80C188XL replacement will be available in Q1.

The Tekmos 80C186 design has been carefully designed to duplicate the original 80C186 in all aspects except for co-processor support.

The TK80C186EB / TK80C188EB is available in the SQFP 80 package. Parts in the PLCC 84 package will be available in Q4. The PQFP 80 package is available on request.

Below is a list of 80C186 microprocessor variants that are either available immediately or under development. If you need a version not listed here then please contact us at This e-mail address is being protected from spam bots, you need JavaScript enabled to view it
