INTRODUCTION

The M80C286 is an advanced 16 bit CHMOS III microprocessor designed for multi-user and multi-tasking

applications that require low power and high performance. The M80C286 is fully compatible with its predeces-

sor the HMOS M80286 and object-code compatible with the M8086 and M80386 family of products. In

addition, the M80C286 has a power down mode which uses less power, making it ideal for mobile applications.

The M80C286 has built-in memory protection that maintains a four level protection mechanism for task isola-

tion, a hardware task switching facility and memory mangement capabilities that map 2 bytes (one gigabyte)

of virtual address space per task (per user) into 2 bytes (16 megabytes) of physical memory.

The M80C286 is upward compatible with M8086 and M8088 software. Using M8086 real address mode, the

M80C286 is object code compatible with existing M8086, M8088 software. In protected virtual address mode,

the M80C286 is source code compatible with M8086, M8088 software which may require upgrading to use

virtual addresses supported by the M80C286’s integrated memory management and protection mechanism.

Both modes operate at full M80C286 performance and execute a superset of the M8086 and M8088 instruc-

tions.

The M80C286 provides special operations to support the efficient implementation and execution of operating

systems. For example, one instruction can end execution of one task, save its state, switch to a new task, load

its state, and start execution of the new task. The M80C286 also supports virtual memory systems by providing

a segment-not-present exception and restartable instructions.
