Product Summary

The N80C186XL12 is a high integration embedded processor. Unless specifically noted, all references to the N80C186XL12 apply to the 80C188XL. References to pins that differ between the N80C186XL12 and the 80C188XL are given in parentheses. The following Functional Description describes the base architecture of the N80C186XL12. The N80C186XL12 is a very high integration 16-bit microprocessor. It combines 15±20 of the most common microprocessor system components onto one chip. The N80C186XL12 is object code compatible with the 8086/8088 microprocessors and adds 10 new instruction types to the 8086/8088 instruction set. The N80C186XL12 has two major modes of operation, Compatible and Enhanced. In Compatible Mode the N80C186XL12 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 (80C186XL only).
