80C286/883

High Performance Microprocessor with Memory

Management and Protection

March 1997

Features

Description

• This Circuit is Processed in Accordance to MIL-STD- The Intersil 80C286/883 is a static CMOS version of the

883 and is Fully Conformant Under the Provisions of NMOS 80286 microprocessor. The 80C286/883 is an

Paragraph 1.2.1.

advanced, high-performance microprocessor with specially

optimized capabilities for multiple user and multi-tasking sys-

tems. The 80C286/883 has built-in memory protection that

supports operating system and task isolation as well as pro-

gram and data privacy within tasks. The 80C286/883

includes memory management capabilities that map 230

• Compatible with NMOS 80286/883

• Static CMOS Design for Low Power Operation

- ICCSB = 5mA Maximum

- ICCOP = 185mA Maximum (80C286-10/883)

- ICCOP = 220mA Maximum (80C286-12/883)

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

bytes (16 megabytes) of physical memory.

• Large Address Space

The 80C286/883 is upwardly compatible with 80C86 and

80C88 software (the 80C286/883 instruction set is a super-

set of the 80C86/80C88 instruction set). Using the 80C286/

883 real address mode, the 80C286/883 is object code com-

patible with existing 80C86 and 80C88 software. In pro-

tected virtual address mode, the 80C286/883 is source code

compatible with 80C86 and 80C88 software but may require

upgrading to use virtual address as supported by the

80C286/883’s integrated memory management and protec-

tion mechanism. Both modes operate at full 80C286/883

performance and execute a superset of the 80C86 and

80C88 instructions.

- 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

- 80C286/883 Real Address Mode

- Protected Virtual Address Mode

• Compatible with 80287 Numeric Data Co-Processor

The 80C286/883 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 segment-not-present excep-
