SDRAM
The DRAM resides in two synchronous DRAM devices soldered directly to the
board. This architecture supports SDRAM memory capacities from 32Mbytes up
to 128Mbytes. The 32-bit SDRAM interface operates at 133MHz.
Flash
The Flash resides in one or two J3 Intel StrataFlashdevices soldered directly to
the board. This architecture supports Flash memory capacities from 8Mbytes up
to 32Mbytes. The 16-bit Flash interface operates at 33MHz.
CompactFlash
The GW2345 supports a single CompactFlash socket located on the rear of the
board. The CompactFlash socket accepts small removable mass storage cards
with storage capacities up to 4Gbytes.
Mini-PCI Sockets
Mini-PCI is a small form factor PCI card that uses the same signal protocol,
electrical specifications, and configuration definitions as conventional PCI. There
are up to four Mini-PCI sockets available on the GW2345. There are a wide
variety of Mini-PCI cards available for expanding the networking functionality of
the GW2345.
Ethernet
The GW2345 includes a Micrel KS8995MA 5-port 10/100 managed switch
connected as a 1-port WAN and a 4-port LAN. The switch supports tag/port-
based VLAN, QoS priority, management, MIB counters and a dual MII interface.
The switch includes five 10/100 transceivers, a high-speed non-blocking switch
fabric, a dedicated address lookup engine, and frame buffer memory. Both
10Base-T and 100Base-TX architectures are supported. The WAN port is
available through a single RJ45 connector. The LAN ports are available through
a 1x4 gang RJ45 connector. All RJ45 connectors have two integrated status
lights. The green status light indicates link and activity. The light is on for link and

blinking for activity. The yellow status light indicates speed. The light is on for
100Mbps and off for 10Mbps.
EEPROM
The Philips PCF8594C is an Electrically Erasable Programmable Read Only
Memory (EEPROM) with 4Kbits of storage. The 4kbits of storage is organized in
a 512 x 8-bit configuration. Additional features include 1,000,000 erase/write
cycles and a 10-year minimum data retention time. Data is transmitted to and
from the EEPROM over the processor I2C bus. The I2C clock frequency is 0 to
100KHz. The I2C 7-bit base address is 50 and 51 hex.
Real Time Clock
The Dallas Semiconductor DS1672 is designed to count seconds and can be
used to derive time-of-day, week, month, and year using software. A battery
ensures uninterrupted operation when the main power supply drops below the
battery voltage. The battery capacity is 35mAH. The real time clock requires
0.425 microamps typical and 1 microamp maximum for backup operation. This
results in a battery life of 4 years minimum and more than 9 years typical. Data is
transmitted to and from the Real Time Clock over the processor I2C bus. The I2C
clock frequency is 0 to 100KHz. The I2C 7-bit base address is 68 hex.
Temperature and Voltage Monitor
The Analog Devices AD7418 provides temperature and voltage monitoring
capability. The GW2345 operating temperature is monitored through this device.
The temperature accuracy is 1C at 25C and 2C over the entire temperature
range of -40C to +125C. The GW2345 input voltage is also monitored through
this device. A resistor divider is used to scale the input voltage. This means that
the monitored value must be multiplied by 23.1 to get the actual input voltage.
Data is transmitted to and from the Temperature and Voltage Monitor over the
processor I2C bus. The I2C clock frequency is 0 to 100KHz. The I2C 7-bit base
address is 28 hex.
Serial I/O
The GW2345 includes two RS232 serial I/O ports. One serial I/O port is available
through a 10-pin header and the other is available through a 9-pin female Dshell
connector. The serial ports are 16550-compliant UARTs with additional depth for
both the transmit and receive buffers. The interface supports transfer rates from
1200bps up to 120Kbps.
Digital I/O
The IXP processor includes a 16 bits of digital I/O. Some of these signals are
used for controlling and monitoring the status of devices local to the GW2345
and some of them are available on a 10-pin header for application use. The
function of each digital I/O signal is described in Section 2, Configuration and
Installation.

USB
The GW2345 includes a version 1.1 Device Controller interface. The interface
operates as a half-duplex, slave-only device at a baud rate of 12Mbps. The
interface does not operate as a USB host. A standard USB Type B connector is
provided on the board.
JTAG Port
A JTAG debug port is available to facilitate program download directly into Flash
memory. See Section 2.7 for instructions on using the Gateworks JTAG
Programmer
Status LED and Push Button Reset
The GW2345 includes a status LED and a push button reset. The LED is
connected to the digital I/O and can be controlled by software. See Section 2,
Configuration and Installation for the mapping of the LED.
DC/DC Converter
A switching DC/DC converter is used to supply power to the GW2345. This
allows the board to support a wide input voltage range and low power operation.
The DC/DC has a minimum input voltage of 6VDC and a maximum of 28VDC.
DO NOT EXCEED THE 28VDC INPUT MAXIMUM OR DAMAGE MAY OCCUR
TO THE BOARD. Also note that if a power over Ethernet injector is used to
power the board, there will be voltage loss due to the resistance of the Ethernet
cable. This should be taken into account when sizing the voltage supply.

2.6. JTAG Programming
The GW2345 Flash memory is programmed through the JTAG port. Gateworks
offers a low cost GW16102 JTAG programmer that enables the developer to
program or recover the Flash image through a standard PC parallel port.
Gateworks also offers a GW16013 JTAG gang programmer for simultaneously
programming up to 16 GW2345 processors in a production environment.
The following are the steps required to use the GW16012 JTAG programmer.
1. Connect the GW16012 JTAG programmer to a PC parallel port using the
standard DB25 cable included with programmer.
2. Connect the 10-pin IDC female from the GW16012 dongle to the GW2345
JTAG connector.
3. Create a bootable DOS floppy with the FLASH.EXE program and the
binary image. The FLASH.EXE program is a DOS program, which must
be run from a DOS prompt, it cannot be run from a Windows DOS box.
The development kit CDROM contains both the FLASH.EXE program and
the default factory programmed image.
4. Insert the DOS bootable floppy, with the FLASH.EXE program and binary
image into the PC’s floppy drive and boot to DOS.
5. Run the FLASH.EXE program with the following syntax
CC:> flash image.bin {p} {v} where p=program, v=verify and image.bin is
the binary image.
Examples:
C:> flash gw2345.bin p
Program the Flash with the gw2345.bin image
C:> flash gw2345.bin v
Verify that the Flash matches the gw2345.bin image
C:> flash gw2345.bin pv
Program and verify the Flash with the gw2345.bin image
2.7. Getting Started
The GW2345 is factory configured with Redboot v1.92 and a uCLinux port
programmed into Flash memory. The software is configured to use the J13 serial
port for a serial console. To get started, connect a serial cable from J13 to
another computer running a terminal software application such as Windows
HyperTerminal. Configure the terminal program for 115,200 baud, 8 data bits, 1
stop bit, no parity and no flow control. For software support, see the IXP4XX
Open Source Linux Developers Guide - http://ixp4xx-osdg.sourceforge.net/ and the
Avila SBC Linux Development Software CDROM included with the development
kit.
