... ISA PNP interface and a PCMCIA slave interface. The MC68SC302 is a descendant of the popular MC68302 Integrated Multiprotocol Processor. The microcoded RISC communications processor from the 68302 was modified to form the core of the 68SC302. The 68000 core and many related system integration features were removed to further optimize the device for passive ISDN card applications ...
