A80386DX-20 Description

Short technical summary and product information.

The Intel 80386, also known as the i386, was a significant 32-bit microprocessor introduced by Intel in 1985. This specific model, the A80386DX-20, operates at a clock speed of 20 MHz and features a 32-bit architecture. It was one of the first microprocessors to implement 32-bit extensions to the 8086 architecture, forming the basis for the x86, IA-32, and i386 architectures still in use today.

 

With 275,000 transistors, the 80386 was the central processing unit for numerous personal computers and workstations. It was designed to be backward compatible, capable of executing most code intended for earlier 16-bit processors. While newer implementations have vastly increased performance, the 80386 architecture remains a common denominator.

 

Although largely obsolete as a personal computer CPU, the 80386 and its derivatives continue to be manufactured for embedded systems, particularly in aerospace technology. The A80386DX-20 is noted as RoHS3 Compliant, with an MSL of Level 1, and REACH Unaffected.
