The MC68302 is a versatile one-chip processor that incorporates the main building blocks needed for the
design of a wide variety of networking and communications products. The MC68302 was the first device to
offer the benefits of a closely coupled, industry-standard, MC68000/MC68008 microprocessor core and a
flexible communications architecture. This multi-channel communications device may be configured to
support a number of popular industry-standard interfaces, including those for the Integrated Services Digital
Network (ISDN) basic rate and terminal adapter applications. Through a combination of architectural and
programmable features, concurrent operation of different protocols is easily achieved using the MC68302.
Data concentrators, modems, line cards, bridges, and gateways are examples of other suitable applications for
this versatile device. The MC68302 is an HCMOS device consisting of an MC68000/MC68008
microprocessor core, a system integration block (SIB), and a communications processor (CP).
