描述 Description
The MC68302 is a versatile one-chip processor that incorporates the main building blocks needed for thedesign 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 anda flexible communications architecture. This multi-channel communications device may be configured tosupport a number of popular industry-standard interfaces, including those for the Integrated ServicesDigital Network (ISDN) basic rate and terminal adapter applications. Through a combination of architecturaland programmable features, concurrent operation of different protocols is easily achieved using theMC68302. Data concentrators, modems, line cards, bridges, and gateways are examples of other suitableapplications for this versatile device. The MC68302 is an HCMOS device consisting of anMC68000/MC68008 microprocessor core, a system integration block (SIB), and a communications processor (CP).This device is still recommended for new designs.
