AMD-762™ System Controller Data Sheet

24416C—December 2001

Preliminary Information

This document describes the features and operation of the

AMD-762 system controller. For a description of the AMD-766

peripheral bus controller, see the AMD-766™ Peripheral Bus

Controller Data Sheet, order# 23167. For a description of the

AMD-768 peripheral bus controller, see the AMD-768™

Peripheral Bus Controller Data Sheet, order# 24467. Key features

of the AMD-762 system controller are provided in this section.
