ABSTRACT:
A microcomputer includes dedicated output transistors for driving a bus for access to an external memory. The output transistors are smaller in size than transistors for other input/output ports. The microcomputer and the external memory are interconnected through a double-sided printed-circuit board forming a multi-chip module (MCM). The module has pin assignments substantially the same as those of a single-chip microcomputer. Selector circuits are included in the module to test specifically the external memory connected to the selectors.
