The Intersil 80C286 is a static CMOS version of the NMOS 80286 microprocessor. The 80C286 is an advanced, highperformance microprocessor with specially optimized capabilities for multiple user and multi-tasking systems. The 80C286 has built-in memory protection that supports operating system and task isolation as well as program and data privacy within tasks. A 25MHz 80C286 provides up to nineteen times the throughput of a standard 5MHz 8086. The 80C286 includes memory management capabilities that map 230 (one gigabyte) of virtual address space per task into 224 bytes (16 megabytes) of physical memory.
