Product Summary

The A80386DX25 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 of virtual memory. The A80386DX25 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.
