32-Bit Microprocessor FACET Board



The 32-Bit Microprocessor module builds on the student’s knowledge of digital circuitry gained in Digital Logic Fundamentals, Model 91014, and Digital Circuit Fundamentals 1 and 2, Models 91015 and 91016. The 80386DX CPU can be used as a stand-alone unit or in conjunction with the FACET base unit to demonstrate microprocessor, memory, and I/O concepts, and communication with analog systems via A-to-D and D-to-A converters.

A keypad and a 2-line x 16-character alphanumeric LCD display allow direct interaction with the CPU. All address, data, and control signals are connected to headers for easy access and expansion to off-board circuits. Additional hardware features include 32-kbyte static RAM, 16-kbyte ROM with monitor, RS-232 serial port, 8-bit parallel port, and LED indicators for address and data buses.

An on-board logic probe, single bus cycle execution mode, and the practical, hands-on approach of the courseware guide students in the analysis and troubleshooting of 32-bit microprocessor systems. The circuit board may be used in the FACET base unit or as a stand-alone trainer.

- When used in the FACET base unit, the course can be performed through the interactive Learning Management System (LMS) format.

- When used as a stand-alone trainer, the course is performed in a conventional way by using the provided student manual and instructor guide. In that case, a power pack (provided with the stand-alone trainer) must be used to supply power to the circuit board if it is used without a base unit.
