80C286

High Performance Microprocessor

with Memory Management and Protection

March 1997

Features

• Compatible with NMOS 80286

• Wide Range of Clock Rates

Description

The Intersil 80C286 is a static CMOS version of the NMOS

80286 microprocessor. The 80C286 is an advanced, high-

performance microprocessor with specially optimized capa-

bilities for multiple user and multi-tasking systems. The

80C286 has built-in memory protection that supports operat-

ing system and task isolation as well as program and data

privacy within tasks. A 25MHz 80C286 provides up to nine-

teen times the throughput of a standard 5MHz 8086. The

80C286 includes memory management capabilities that

- 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)

map 2 (one gigabyte) of virtual address space per task

into 2 bytes (16 megabytes) of physical memory.

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 Operat-

ing Systems

• Two 80C86 Upward Compatible Operating Modes

- 80C286 Real Address Mode

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 performance and execute a

superset of the 80C86 and 80C88 instructions.

- PVAM

The 80C286 provides special operations to support the effi-

cient 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 80C286 also supports virtual

memory systems by providing a segment-not-present excep-

tion and restartable instructions.

• Compatible with 80287 Numeric Data Co-Processor

• High Bandwidth Bus Interface (25 Megabyte/Sec)

• Available In

- 68 Pin PGA (Commercial, Industrial, and Military)

- 68 Pin PLCC (Commercial and Industrial)
