Product Summary

The QU80386EXTC33 embedded processor is a highly integrated, 32-bit, fully static processor optimized for embedded control applications. With a 16-bit external data bus, a 26-bit external address bus, and Intel System Management Mode (SMM), the QU80386EXTC33 brings the vast software library of Intel386 architecture to embedded systems. It provides the performance benefits of 32-bit programming with the cost savings associated with 16-bit hardware systems.
