Description
The TS68C000 reduced power consumption device dissipates an order of magnitude
less power than the HMOS TS68000. The TS68C000 is an implementation of the
TS68000 16/32 microprocessor architecture. The TS68C000 has a 16-bit data bus
and 24-bit address bus while the full architecture provides for 32-bit address and data-
buses. It is completely code-compatible with the HMOS TS68000, TS68008 8-bit data
bus implementation of the TS68000 and the TS68020 32-bit implementation of the
architecture. Any user-mode programs written using the TS68C000 instruction set will
run unchanged on the TS68000, TS68008 and TS68020. This is possible because the
user programming model is identical for all processors and the instruction sets are
proper sub-sets of the complete architecture.

Introduction
This detail specification contains both a summary of the TS68C000 as well as detailed set of
parametrics. The purpose is twofold to provide an instruction to the TS68C000 and support for
the sophisticated user. For detail information on the TS68C000, refer to "68000 16-bit micropro-
cessor user’s manual".
