1 Introduction
The 78Q8430 STEM Demo Board (D8430T3B_STEM) is a design example for a 10/100BASE-TX
MAC+PHY ST Microelectronics STEM daughter card. The Demo Board plugs directly into STi5100 and
STi5514 Evaluation Systems. The network connection is provided by the 78Q8430 which is a single chip
auto-sensing, auto-switching (auto-negotiation or parallel detect modes and auto-MDIX) 10/100BASE-TX
Fast Ethernet transceiver with full duplex operation capability. The device is designed specifically for the
Audio/Visual (A/V) and Set Top Box (STB) markets and is easily interfaced to available A/V and STB core
processors.
The 78Q8430 is compliant with applicable IEEE-802.3 standards. MAC and PHY configuration and
status registers are provided as specified by IEEE802.3u. The integrated MAC is supported by an
internal 32KByte transmit and receive SRAM FIFO. The partition of transmit and receive queues are
configurable through software, allowing the 78Q8430 to be tuned for specific applications. The device
contains hardware support for TCP-IP checksum and ARC address recognition.
The 78Q8430 STEM Demo Board includes support for the following 78Q8430 hardware interface
features:
The system bus interface operates like external memory with an active low chip select.
A configurable bus interface with support for little endian and big endian formats.
Supports an asynchronous 100 MHz (max) bus clock for STi5100/5514 o peration.
Supports 32-bit, 16-bit and 8 bit wide data bus formats.
Optional EEPROM interface for configuration data.
Two programmable LED outputs for PHY status.
Single +3.3V power supply voltage with common ground plane.
A host processor interfaces directly to the FIFO via the GBI interface. The D8430T3B_STEM board is
configured for 16-bit big endian bus format by default. The bus can optionally be configured for 32-bit or
8-bit bus widths or little endian format. Figure 1 shows the 78Q8430 system interfaces.

This document describes the setup and configuration of the 78Q8430 STEM Demo Board. The demo
board requires operation with a +3.3V power supply sourced from the STEM bus interface on the STi5100
evaluation board. The 78Q8430 PHY interfaces to a CAT5 UTP cable via a 1:1 transformer.
The supplied software driver includes support for ST/OS-20. The included 78Q8430 Softwar e Driver
Development Guidelines and 78Q8430 Software User Guide for ST/OS-20 describe the software
interfacing requirements for quick driver integration and prompt system evaluatio n of the 78Q8430.
Use this document with those listed in the Related Documentation section.

2 Hardware Setup
2.1 Jumper and Dip Switch Settings
The 78Q8430 STEM Demo Board utilizes various jumpers (J5, J6, and J8) and dip switches (S3) for
establishing the startup configuration of the 78Q8430 device. Figure 2 shows the location of the jumpers
and dip switch. Table 1 and Table 2 describe the jumper and dip switch options. The jumper and switch
numbers and settings are printed on the demo board.
