The TK80C186EC Microprocessor

The TK80C186EC microprocessor, the Tekmos version of the 80C186EC, is now in production by Tekmos. The TK80C186EC is available in 100 pin PQFP package and, using an adapter card, the 100 pin BQFP.

The 80C186 was originally an Intel design. Since its inception, a number of companies have made different versions the 80C186. Tekmos developed an 80C186 core design that can be used to replace many variations of the 80C186. The Tekmos 80C186 design was carefully designed to duplicate the original 80C186 in all aspects except for co-processor support.

One variation of the 80C186 is the 80C186EB. Tekmos offers this as the TK80C186EB / TK80C188EB which directly replaces the Intel 80C186EB / 80C188EB microprocessors. They are available from Tekmos in the 80 pin SQFP package and the 84 pin PLCC 84. The 80 pin PQFP package is available on request.

The TK80C186EC is a direct replacement for the Intel 80C186EC, another variation of original 80C186. Tekmos added a DMA controller, an interrupt controller, and more parallel ports in developing this current version. It is available in a 100 pin PQFP and adapted 100 pin BQFP. While the actual 100 pin BQFP package is not available, Tekmos has made an adapter card version which directly fits the 100 pin BQFP footprint and outline. Look for the Tekmos article on how Tekmos adapter cards circumvent the problem of obsolete packages.
