Overview
SEMICONDUCTOR 80C286 March 1997 High Performance Microprocessor with Memory Management and Protection Features Description • Compatible with NMOS 80286 • Wide Range of Clock Rates - DC to 25MHz (80C286-25) - DC to 20MHz (80C286-20) - DC to 16MHz (80C286-16) - DC to 12.
5MHz (80C286-12) - DC to 10MHz (80C286-10) • Static CMOS Design for Low Power Operation - ICCSB = 5mA Maximum - ICCOP = 185mA Maximum (80C286-10) 220mA Maximum (80C286-12) 260mA Maximum (80C286-16) 310mA Maximum (80C286-20) 410mA Maximum (80C286-25) • High Performance Processor (Up to 19 Times the 8086 Throughput) • Large Address Space • 16 Megabytes Physical/1 Gigabyte Virtual per Task • Integrated Memory Management, Four-Level Memory Protection and Support for Virtual Memory and Operating Systems • Two 80C86 Upward Compatible Operating Modes - 80C286 Real Address Mode - PVAM The Harris 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.
The 80C286 is upwardly compatible with 80C86 and 80C88 software (the 80C286 instruction set is a superset of the 80C86/80C88 instruction set).
Using the 80C286 real address mode, the 80C286 is object code compatible with existing 80C86 and 80C88 software.
In protected virtual address mode, the 80C286 is source code compatible with 80C86 and 80C88 software but may require upgrading to use virtual address as supported by the 80C286’s integrated memory management and protection mechanism.
Both modes operate at full 80C286 perform...
