Getting started
A ZEUS Quickstart Manual is provided with each Development Kit to enable you to set up and start using the ZEUS board. Please read the relevant manual and follow the steps explaining how to set up the board. Once you have completed this task, and your ZEUS system is working, you can start adding further peripherals enabling development to begin.
This section explains how to set up and use some of the features of the ZEUS. For more detailed information on any aspect of the board see the section Detailed hardware description, page 18.
Using the ZEUS
Using the CompactFlash socket
The ZEUS is fitted with a Type I/II CompactFlash socket mounted on the solder side of the board. The socket is connected to Slot 0 of the PXA270 PC card interface. It supports 3.3V Type I and II CompactFlash cards, for both memory and I/O. The ZEUS supports hot swap changeover of the cards and notification of card insertion.
For more details see Expansion interfaces, page 38.
5V CompactFlash cards are not supported.
Using the serial interfaces (RS232/422/485)
The four standard serial port interfaces on the ZEUS are fully 16550 compatible. Connection to the serial ports is made via two DB9 connectors, a 20-way header and a simple 5 way header. The pin assignment of the 20 way header has been arranged to enable 9-way IDC D-Sub plugs to be connected directly to the cable. See the section J19 – Serial ports – COM3/4, page 88, for pin assignments and connector details.
See the section Serial COM ports, page 53, for further details.
Using the audio features
There are four audio interfaces supported on the ZEUS: amp out, line out, line in and microphone. The line in, line out and amp interfaces support stereo signals and the
microphone provides a mono input. The amplified output is suitable for driving an 8Ω load with a maximum power output of 250mW per channel.
Connections are routed to J11. See the sections Audio, page 49, and J4 – Audio connector, page 79, for further details.
Using the USB ports
The standard dual USB type ‘A’ connector is provided on the front panel. See the sections USB, page 51, and J8 – USB connector, page 81, for further details.

Using the Ethernet interface
The boot loader configures the Davicom DM9000A 10/100BaseTX Ethernet controller. Connection is made via a dual RJ45 connector. See the sections Ethernet, page 52, and J6 – Ethernet connector, page 80, for further details.
Using the PC/104 expansion bus
PC/104 modules can be used with the ZEUS to add extra functionality to the system. This interface supports 8/16 bit ISA bus style peripherals.
Eurotech Ltd has a wide range of PC/104 modules, which are compatible with the ZEUS. These include modules for digital I/O, analogue I/O and motion control. Please contact Eurotech Sales (see page 97) if a particular interface you require does not appear to be available as these modules are in continuous development.
In order to use a PC/104 board with the ZEUS it should be plugged into J12 for 8-bit cards and J12/J13 for 8/16-bit cards. See the sections ZEUS PC/104 interface details, page 41, and J12 & J13 – PC/104 connectors, page 84, for further details.
The ISA interface on the ZEUS does not support DMA, shared interrupts and some access modes. See the section PC/104 interrupts, page 42, for details about PC/104 interrupt use.
The ZEUS provides +5V to a PC/104 add-on board via the J12 and J13 connectors. If a PC/104 add-on board requires a +12V supply, then +12V must be supplied to the ZEUS power connector J2 pin 4. If –12V or –5V are required, these must be supplied directly to the PC/104 add-on board.
Using the ZEUS Modem Modules
The ZEUS Modem modules can be used with the ZEUS to add wireless and GPS functionality to the system. Various wireless modems are supported to provide packet data, circuit switched data and voice connectivity on a wireless network. A 12 channel GPS receiver is also available on the ZEUS Modem module. The ZEUS Modem module is fitted on the solder side of the ZEUS board (connector J23).
The FFUART serial port of PXA270 is used to communicate with the wireless modem, and STUART is used to communicate with GPS module. See the sections Wireless modem and GPS receiver, page 35, and J23 – Wireless modem/GPS module interface, page 91, for further details.
Using the ZigBee Module
The ZEUS ZigBee module can be used with the ZEUS to provide ZigBee (www.zigbee.org) and IEEE 802.15.4 compatible wireless connectivity. The BTUART serial port of PXA270 is used to communicate with the ZigBee module. The ZigBee module is fitted on the solder side of the ZEUS board (connector J21). For further details, see sections IEEE802.15.4 / ZigBee module, page 37.

PXA270 processor
The ZEUS board is based on a PXA270 processor. The PXA270 processor is an integrated system-on-a-chip microprocessor for high performance, low power portable handheld and handset devices. It incorporates the Intel XScale technology with on-the- fly voltage and frequency scaling and sophisticated power management.
The PXA270 processor complies with the ARM Architecture V5TE instruction set (excluding floating point instructions) and follows the ARM programmer’s model. The PXA270 processor also supports Intel Wireless MMX integer instructions in applications such as those that accelerate audio and video processing.
The features of the PXA270 processor include:
•Intel XScale core.
•Power management.
•Internal memory - 256KB of on-chip RAM.
•Interrupt controller.
•Operating-system timers.
•Pulse-width modulation unit (PWM).
•Real time clock (RTC).
•General-purpose I/O (GPIO).
•Memory controller.
•DMA controller.
•Serial ports:
-3x UART.
-Fast infrared port.
-I2C bus port.
-AC97 Codec interface.
-I2S Codec Interface.
-USB host controller (2 ports).
-USB client controller.
-3x synchronous serial ports (SSP).
•LCD panel controller.
•Multimedia card, SD memory card and SDIO card controller.
•Memory stick host controller.
•Mobile scalable link (MSL) interface.
•Keypad interface.
•Universal subscriber identity module (USIM) interface.
•Quick Capture camera interface.
•JTAG interface.
•356-pin VF-BGA packaging.

Detailed hardware description |
|
|
The design supports 520MHz, 416MHz and 312MHz speed variants of the PXA270 processor. The standard variant of the ZEUS board is fitted with the 520MHz version of PXA270. The maximum speed available for extended temperature versions of the ZEUS is 416MHz.
A 13MHz external crystal is used to run the PXA270 processor. All other clocks are generated internally in the processor.
The PXA270 processor family provides multimedia performance, low power capabilities and rich peripheral integration. Designed for wireless clients, it incorporates the latest Intel advances in mobile technology over its predecessor, the PXA255 processor. The PXA270 processor features scalability by operating from 104MHz up to 520MHz, providing enough performance for the most demanding control and monitoring applications.
PXA270 is the first Intel Personal Internet Client Architecture (PCA) processor to include Intel Wireless MMX technology, enabling high performance, low power multimedia acceleration with a general-purpose instruction set. Intel Quick Capture technology provides a flexible and powerful camera interface for capturing digital images and video. Power consumption is also a critical component. Wireless Intel SpeedStep technology provides the new capabilities in low power operation.
The processor requires a number of power supply rails. All voltage levels are generated on-board from either the DC/DC PSU or from the single +5V power input. The ZEUS uses a specialized Power Management IC to support Intel SpeedStep technology.
The PXA270 processor is a low power device and does not require a heat sink for operating temperatures up to 85°C (185°F).

On-Board GPIO expanders pin assignments
Two GPIO expanders (MAX7313) are used to provide additional GPIOs for use with different on-board peripherals. The GPIO expanders are connected to the I2C bus of PXA270 and are accessible through I2C bus addresses 0x21 and 0x22.
The following tables summarize the use of the 17 GPIO pins of MAX7313 on ZEUS board, and indicate their direction and active level.
