MC68SC302无源ISDN协议控制器应用开发系统结构及功

• MC68SC302 operating at 20.48Mhz.
• ISA half-card form factor modified with PCMCIA extender card.
• Host PC connection via either ISA Bus or PCMCIA bus.
• ISA Plug and Play Interface.
• Powered by the ISA or PCMCIA connectors with option to power from bench supply.
• The U interface transceiver MC145572 configurable to either NT or LT mode.
• The S/T interface transceiver MC145574 configurable to either TE or NT mode.
• Options to communicate with U and S/T transceivers via either the IDL/SCP bus or the GCI bus.
• Logic analyzer connectors to probe MC68SC302 and ISA/PCMCIA bus activity.
• 128-pin expansion connector providing access to the SC302 pins for customer daughter cards. This
includes access to the ISA/PCMCIA bus pins.
• Options for three types of serial EEPROM for the PCMCIA or ISA Configuration.
