The Intersil 80C286/883 is a static CMOS version of the
NMOS 80286 microprocessor. The 80C286/883 is an
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
(one gigabyte) of virtual address space per task into 224
bytes (16 megabytes) of physical memory.
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.
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-
tion and restartable instructions.

NOTES:
2. IBHL should be measured after lowering VIN to GND and then raising to 1.0V on the following pins: 36-51, 66, 67.
3. IBHH should be measured after raising VIN to VCC and then lowering to 3.0V on the following pins: 4-6, 36-51, 66-68.
4. ICCSB should be tested with the clock stopped in phase two of the processor clock cycle. VIN = VCC or GND, VCC = 5.5V, outputs unloaded.
5. ICCOP measured at 10MHz for the 80C286-10/883 and 12.5MHz for the 80C286-12/883. VIN = 2.4V or 0.4V, VCC = 5.5V, outputs unloaded.
6. ISH should be measured after raising VIN to VCC and then lowering to 0V on pins 53 and 54.
