Integrierte Schaltung für Karten anwendbar in Systemen mit verschiedenen Bitzahlen.

摘要

In accordance with the present invention, provided is a card type integrated circuit for a 8-bit system and a 16-bit system which includes one or more circuit devices (16) loaded on a substrate (14) and a plurality of terminals (15) connected to the circuit devices (16) through an I/O bus system to input and output data from and to external equipment, and a connector which includes a guide section (28) having a guide groove (28a) for guiding the card type integrated circuit and a housing section (29) having contact pins (30) for connecting to the terminals (15) of the card type integrated circuit. In the layout and assignment of the terminals (15) and the contact pins (30), the terminals for signals common to the 8-bit system and the 16-bit system are arranged on the central portion and the other terminals (15) for signals dedicated to the 16-bit system are arranged on both end portions. Consequently, it is possible to use a single kind of connector in common for connecting to either of the 8-bit system card or the 16-bit system card.
