TTekmos 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 Tekmos 80C186 design has been carefully designed to duplicate the original 80C186 in all aspects except for co-processor support.
- TK80C186EB / TK80C188EB
80-pin QFP, 84-pin PLCC
- TK80C186EC / TK80C188EC
Tekmos has developed a 68HC705 design that can be used to replace many variations of the 68HC05 and 68705 microcontrollers. Our first part will be the TK68HC05B6, with 6K of ROM. Our second part will be the user programmable TK68HC705C8A / TK68HC705C9A devices. These parts will use flash memory as contrasted to the original part's One Time Programmable (OTP) EPROM. The 68HC705B16N and 68HC705B32 will be available with a longer lead time. The Tekmos 68HC05 design has been carefully designed to duplicate the original 68HC05 on a clock for clock basis. This guarantees complete compatibility with existing code. Even timing loops will work perfectly.
20-pin PDIP, 20-pin SOIC
Tekmos has developed a 68HC711 design that can be used to replace many variations of the 68HC11 and 68HC711 microcontrollers. The Tekmos 68HC711 design has been carefully designed to duplicate the original 68HC11 on a clock for clock basis. This guarantees complete compatibility with existing code. Even timing loops will work perfectly.

The TK68020 is a functional equivalent of the Motorola M68020 and they are pin-for-pin compatible. It is a full 32-bit implementation of the M68000 family of microprocessors from Motorola. The TK68020 is a full 32-bit implementation of the 68000 family of microprocessors from Motorola. The TK68020 is implemented with 32-bit registers and data paths, 32-bit addresses, a rich instruction set, and versatile addressing modes. The TK68020 is object-code compatible with earlier members of the 68000 family and has the added features of new addressing modes in support of high-level languages, an on-chip instruction cache, and a flexible coprocessor interface with full IEEE floating-point support available. The internal operations of this microprocessor operate in parallel, allowing multiple instructions to be executed concurrently. The asynchronous bus structure of the TK68020 uses a non-multiplexed bus with 32 bits of address and 32 bits of data. The processor supports a dynamic bus sizing mechanism that allows the processor to transfer operands to or from external devices while automatically determining device port size on a cycle-by-cycle basis. The dynamic bus interface allows access to devices of differing data bus widths, in addition to eliminating all data alignment restrictions.
