11 / 87 page PIN DESCRIPTION Release 1.3 - January 29, 2002 11/87 This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice. 2. PIN DESCRIPTION 2.1. INTRODUCTION The STPC Elite integrates most of the functionalities of the PC architecture. As a result, many of the traditional interconnections between the host PC microprocessor and the peripheral devices are totally internal to the STPC Elite. This offers improved performance due to the tight coupling of the processor core and these peripherals. As a result many of the external pin connections are made directly to the on-chip peripheral functions. Figure 2-1 shows the STPC Elite external interfaces. It defines the main buses and their function. Table 2-1 describes the physical implementation listing signals type and their functionality. Table 2-2 provides a full pin listing and description of pins. Table 2-7 provides a full listing of pin locations of the STPC Elite package by physical connection. Note: Several interface pins are multiplexed with other functions, refer to Table 2-4 and Table 2-5 for further details Table 2-1.
