MC68SC302 APPLICATION DEVELOPMENT SYSTEM

The MC68SC302 Application Development System (ADS) is a platform for developing a passive terminal

adaptor using the MC68SC302. In addition to being an ISA half-card form factor plug-in card, the MC68SC302

can also be plugged into a PC card slot for development of PC card applications. The board includes both an

MC145572 U interface transceiver and an MC145574 S/T interface transceiver along with the associated line

interface circuitry. A 128-pin expansion connector is onboard for customer specific circuits such as a POTs

interface or a modem datapump. Logic analyzer connectors provide convenient access to ISA and PCMCIA

bus signals. Figure 6 shows the ADS block diagram.
