Product Summary

The following Functional Description describes the base architecture of the A80C186XL20. The A80C186XL20 is a very high integration 16-bit microprocessor. It combines 15±20 of the most common microprocessor system components onto one chip. The A80C186XL20 is object code compatible with the 8086/8088 microprocessors and adds 10 new instruction types to the 8086/8088 instruction set. The A80C186XL20 has two major modes of operation, Compatible and Enhanced. In Compatible Mode the A80C186XL20 is completely compatible with NMOS 80186, with the exception of 8087 support. The Enhanced mode adds three new features to the system design. These are Power-Save control, Dynamic RAM refresh, and an asynchronous Numerics Coprocessor interface (A80C186XL20 only).
