High Performance Microprocessor with Memory Management and Protection

The Intersil is a static CMOS version of the NMOS 80286 microprocessor. The is an advanced, high-performance microprocessor with specially optimized capabilities for multiple user and multi-tasking systems. The 80C286/883 has built-in memory protection that supports operating system and task isolation as well as program 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 superset of the 80C86/80C88 instruction set). Using the 80C286/ 883 real address mode, the 80C286/883 is object code compatible with existing 80C86 and 80C88 software. In protected 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 protection 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 exception and restartable instructions.

2. IBHL should be measured after lowering VIN to GND and then raising 1.0V on the following pins: IBHH should be measured after raising VIN to VCC and then lowering 3.0V on the following pins: 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 or 0.4V, VCC = 5.5V, outputs unloaded. 6. ISH should be measured after raising VIN to VCC and then lowering 0V on pins 53 and 54.
