Product Descriptions

The Intel386 DX Microprocessor is an entry-level 32-bit microprocessor designed for single-user applications and operating systems such as MS-DOS and Windows. The 32-bit registers and data paths support 32-bit addresses and data types. The processor addresses up to four gigabytes of physical memory and 64 terabytes (2** 46) of virtual memory. The integrated memory management and protection architecture includes address translation registers, multitasking hardware and a protection mechanism to support operating systems. Instruction pipelining, on-chip address translation, ensure short average instruction execution times and maximum system throughput. 

The Intel386 DX CPU offers new testability and debugging features. Testability features include a self-test and direct access to the page translation cache. Four new breakpoint registers provide breakpoint traps on code execution or data accesses, for powerful debugging of even ROM-based systems. 

Object-code compatibility with all 8086 family members (8086, 8088, 80186, 80188, 80286) means the Intel386 DX offers immediate access to the world’s largest microprocessor software base.
