HOW TO USE THIS DOCUMENT
Even though it has a 16-bit external data bus, the
embedded ULP Intel486 GX processor has charac-
teristics similar to the 32-bit Intel486 SX processor.
This document describes the new features of the
embedded ULP Intel486 GX processor. Some
Intel486 SX processor information is also included to
minimize the dependence on the reference
documents.

The tables and figures show “no-connects” as “N/C.”
These pins should always remain unconnected.
Connecting N/C pins to V
, V
, V
, or any other
signal pin can result in component malfunction or
incompatibility
with
