Product Brief  
Passive ISDN Protocol Engine  
The MC68SC302 Passive ISDN Protocol Engine (PIPE) is a communication controller optimized for ISDN  
passive cards, with an 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. The serial  
communication channels (SCC) have been optimized for supporting a full ISDN basic rate interface. The three  
SCCs support two 64kbit per second B-channels and one 16kbit per second D-channel. The 68SC302 connects  
gluelessly to Motorola’s MC145572 U transceiver or MC145574 S/T transceiver and, as an added bonus,  
eliminates the need for a second oscillator for the transceiver chip.  
MC68SC302 KEY FEATURES  
• ISA Bus Interface  
ISA Plug and Play Interface  
Glueless Connections to ISA  
24mA Buffers for ISA Bus Pins  
Full Support of Plug and Play Standard  
All Chip Registers Accessed from ISA Bus.  
Support for 8- or 16-bit I/O or Memory ISA Cycles  
11 Selectable Interrupt Output Pins to ISA Bus.  
Additional Chip Select Allows Another Device to Be Accessed from the ISA Bus.  
2
Plug and Play Register Settings Stored in External Low Cost E PROM.  
• PCMCIA Interface  
PC Card 95 Compatible  
Two CIS Storage Options:  
2
• CIS stored in Serial E PROM and Downloaded At Runtime to Internal Dual Port RAM  
2
• CIS Optionally Stored in Parallel E PROM on the PC Card Bus with Dedicated Chip Select, Saving  
Dual Port RAM Buffer Space and Always Available for PC Accesses.
