1 Introduction

The ETX approach of custom carrier combined with off the shelf system core is an excellent
solution when you need to customize but lack the time or quantity for a complete redesign. It fits
most system integration projects with production volumes from 500 to 10,000 pcs per year. The
ETX concept has a great many advantages over full custom designs. It reduces engineering
complexity, lowers the threshold for total project quantity and last but not least brings your
product to the market in no time. The average time to design a carrier board is less than half the
time of a full custom OEM board.

ETX-Proto is a standard ATX size carrier board.Together with the ETX module of your choice and
off the shelf add-on cards, you can quickly emulate the functionality of your desired end
product for software development and hardware verification.

To build a functional prototype of your target system you will need:

f ETX module
f ETX-Proto
f ISA, PCI or Mini PCI add-on cards
f Storage or Flash disk solution

ETX Proto supports up to 4 PCI add-on cards and 3 ISA cards.
In addtion to the functions on the ETX module, ETX-Proto adds the following:

f Secondary I/O for COM3/4 and LPT2
f Secondary hardware monitor
f PCI based debug display for POST code readout
f I2C based GPIO
f Audio amplifier

Page 7ETX-Proto User’s Manual

2 Special Functions

2.1 Secondary Super I/O

ETX-Proto uses the SMSC FDC37C669, an ISA based Super I/O chip to provide COM3,
COM4, LPT2 and FDD2 in addtion to the primary Super I/O on the ETX module. Support for
this secondary I/O is included standard in the BIOS of all ETX modules that support the ISA
bus.

2.2 Carrier Hardware Monitor

A W83782D Winbond H/W monitoring IC provides addtional hardware monitor functions. The
W83782D can be used to monitor several critical hardware parameters of the system that cannot
be monitored by the hardware monitor on the ETX module such as power supply voltages on
the carrier board, fan speeds, and system temperatures.

2.3 Integrated Debug Port

ETX-Proto supports an integrated debug port on board. The port 80 function is implemented with
two CPLD chips on the PCI bus interface.

2.4 Audio Power Amplifier

The onboard stereo audio power amplifier contains two identical amplifiers capable of delivering
6 W per channel of continuous average power into a 4-W load at 10% THD+N or 5 W per channel
at 1% THD+N. The gain of each channel is fixed at 20 dB. The amplifier features a mute/standby
function for power-sensitive applications.

2.5 General Purpose I/O

The F75111R is a low power general purpose IO chip providing 20 GPIO.
Most GPIO pins can be programmed to be power LEDs. Level or pulse modes can be

programmed by registers. Two power-down modes (Manual or Smart) can be selected to
save power and control the total consumption to under 10uA.

The F75111R also includes two sets of watchdog timers. One watchdog timer’s timeout unit
is set to seconds with a range of 0 to 127 seconds. The other Watchdog timer is set to
seconds or minutes and the range is 0 to 256 seconds or minutes.

2.6 I2C and SMBus Devices

The SMBus (I2C bus) controller is integrated in the ETX core module. There are several
slave devices that reside on the SMBus (I2C bus) of the ETX-Proto. The addresses are as
follows:

6.2 Pin-Out Compatibillity

All pin-outs on X1, X2, X3 and X4 on the ETX-Proto comply with pin-out and signal descrip­tion used in the original “ETX Specification ver 2.6”. This document includes a description of
pin-outs, signal descriptions and mechanical characteristics of the ETX formfactor.

An addtional document called “ETX Design Guide” is a general introduction to carrier board
design for ETX core modules.
