PIN DESCRIPTION

2. PIN DESCRIPTION

2.1 INTRODUCTION

The STPC Consumer integrates most of the func-

tionalities of the PC architecture. As a result, many

of the traditional interconnections between the

host PC microprocessor and the peripheral devic-

es are totally internal to the STPC Consumer. This

offers improved performance due to the tight cou-

pling of the processor core and these peripherals.

As a result many of the external pin connections

are made directly to the on-chip peripheral func-

tions.

Figure 2-1 shows the STPC Consumer’s external

interfaces. It defines the main busses and their

function. Table 2-1 describes the physical imple-

mentation listing signal types and their functional-

ities. Table 2-2 provides a full pin listing and de-

scription. Table 2-3 provides a full listing of the

STPC Consumer pin locations of package by

physical connection. Please refer to the pin alloca-

tion drawing for reference.
