Getting started
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 17.
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 36.
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 80, for pin assignments and connector details.
See the section Serial COM ports, page 47, 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 45, and J4 – Audio
connector, page 71, 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 46, and J8 – USB connector, page 73, for further details.

ZEUS user manual
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 47, and
J6 – Ethernet connector, page 72, 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 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 125) 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 38, and J12 & J13 – PC/104 connectors, page 76, 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 39, 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 34, and J23 – Wireless modem/GPS module interface,
page 83, 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 35.

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).

Detailed hardware description
Real time clock
The ZEUS uses an external real time clock (RTC) (Intersil ISL1208) to store the date and
time, and provide power management events. The RTC is connected to the I2C bus of
the PXA270 processor and is accessible through I2C bus address 0x6F. The RTC is
battery backed.
The accuracy of the RTC is based on the operation of the 32.768 KHz watch crystal. The
calibration tolerance is ±20ppm, which provides an accuracy of +/-1 minute per month
when the board is operated at an ambient temperature of +25°C (+77°F). When the
board is operated outside this temperature the accuracy may be degraded by
-0.035ppm/ °C² ±10% typical. The watch crystal’s accuracy will age by ±3ppm max in the
first year, then ±1ppm max in the year after, and logarithmically decrease in subsequent
years.
The Intersil ISL1208 RTC provides the following basic functions:
•
Real time clock/calendar:
- Tracks time in hours, minutes and seconds.
- Day of the week, day, month and year.
•
Single alarm:
- Settable to the second, minute, hour, day of the week, day or month.
- Single event or pulse interrupt mode.
•
2 bytes battery-backed user SRAM.
•
I2C interface.
PXA270 has an internal real time clock, which doesn’t keep time after hardware reset,
and should only be used as a wake-up source from deep-sleep.

ZEUS user manual
Watchdog timer
The ZEUS uses an external watchdog timer (MAX6369) which can be used to protect
against erroneous software. This is a programmable watchdog timer that can be adjusted
for timeout periods of 1ms, 10ms, 30ms, 100ms, 1s, 10s and 60s. The board is reset
when timeout occurs. The MAX6369 watchdog timer can be programmed using the WD
setup register provided within the CPLD. The register is memory mapped (accessible
through CS5#). The WDT is disabled upon reset, and remains so until enabled by the
software.
The following table shows the WD setup register bit definitions:

WDI: Watchdog Input. If WDI remains either high or low for the
duration of the watchdog timeout period (tWD), WDT triggers a reset
pulse. The internal watchdog timer clears whenever a reset pulse is
asserted or whenever WDI sees a rising or falling edge.

The ZEUS has four types of memory fitted:
•
32 or 64MB resident Flash disk containing:
- Boot loader to boot operating system.
- Operating system.
- Application images.
•
64, 128 or 256MB of SDRAM for system memory.
•
Static RAM, as follows:
- 256KB of SRAM internal to PXA270.
- 256KB of SRAM external to PXA270 (battery backed).
•
32
128 bytes of configuration EEPROM on the I²C bus.

Detailed hardware description
Flash memory
The ZEUS supports 32MB or 64MB of Spansion (AMD) MirrorBit Flash memory for the
boot loader, OS and application images. The Flash memory is arranged as 128Mbit x 16bit (32MB device) or as 256Mbit x 16-bit (64MB device).
The Flash memory array is divided into equally sized symmetrical blocks that are
64-Kword in size (128KB) sectors. A 256Mbit device contains 256 blocks, and a 512Mbit
device contains 512 blocks.
Whenever the Flash memory is accessed the ‘Flash’ access LED is illuminated.
SDRAM
There are two standard memory configurations supported by the ZEUS: 64MB or 128MB
of SDRAM located in banks 0 and 1. The SDRAM is configured as 16MB x 32-bit
(64MB), or 32MB x 32-bit (128MB). 64MB configuration is using 2 devices, and 128MB
configuration is using 4 devices, each with 4 internal banks of 4MB x 16-bit. Optional
256MB configuration is using 4 devices, each with 4 internal banks of 8MB x 16-bit.
These are surface mount devices soldered to the board. The size of memory fitted to the
board is detected by software to configure the SDRAM controller accordingly.
The SDRAM memory controller is set to run at frequency of 104MHz.
Static RAM
The PXA270 processor provides 256KB of internal memory-mapped SRAM. The SRAM
is divided into four banks, each consisting of 64KB.
The ZEUS also has an external 256KB SRAM device fitted, arranged as 256Kbit x 8-bits.
Access to the device is on 16-bit boundaries, whereby the least significant byte is the
SRAM data and the 8-bits of the most significant byte are ‘don’t care’ bits. The reason for
this is that the PXA270 is not designed to interface to 8-bit peripherals. This arrangement
is summarized in the following data bus table:
Most significant byte

Don’t Care
Least significant byte

SRAM Data
The external SRAM is non-volatile while the on-board coin cell battery is fitted.
Configuration EEPROM
The configuration EEPROM is interfaced directly to PXA270’s I2C controller. It is a
Microchip 24AA01 1Kbit EEPROM organized as one block of 128 x 8-bit memory.
The configuration EEPROM is addressable at I²C serial bus address 0x50 and is
accessed in fast-mode operation at 400KB/s.

ZEUS user manual
PC/104 interface
The ZEUS PC/104 interface is emulated from the PXA270 PC card interface to support
8/16 bit ISA bus style signals. As the interface is an emulation, the ZEUS does not
support some PC/104 features. Please refer to the section Unsupported PC/104 interface
features on page 40 for specific details.
Add-on boards can be stacked via the PC/104 interface to enhance the functionality of
the ZEUS. Eurotech has an extensive range of PC/104 compliant modules and these can
be used to quickly add digital I/O, analogue I/O, serial ports and motion control.
The ISA bus is based on the x86 architecture and is not normally associated with RISC
processors. It is generally necessary to modify standard drivers to support any third party
PC/104 modules.
Any PC/104 add-on board attached to the ZEUS is accessible from the PC card memory
space socket 1. The memory map is shown in the following table:

ZEUS PC/104 interface details
The PC/104 bus signals are compatible with the ISA bus electrical timing definitions.
All signals between the PXA270 and the PC/104 are buffered. When the PC/104 bus is
not in use, all output signals with the exception of the clock signals are set to their
inactive state.
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.
The reset signal applied to the PC/104 bus is combination of the RESET_OUT# pin of
PXA270 and an additional circuit that monitors +5V supply.
Due to the specific power management requirements of the PXA270, there is no reset
generated to PXA270 if the +5V supply is below its limits. If the reset is generated to the
PC/104 bus by the +5V monitoring IC, an interrupt can be asserted to PXA270 on
GPIO20.

Detailed hardware description
PC/104 interrupts
The PC/104 interrupts are combined together so that any interrupt generated on the
PC/104 interface generates a single interrupt on the GPIO17 pin of the PXA270
processor.
Reading the PC104_IRQ register located at the address 0x12800000 can identify the
PC/104 interrupting source. The registers indicate the status of the interrupt lines at the
time the register is read. The relevant interrupt has its corresponding bit set to ‘1’. The
PXA270 is not designed to interface to 8-bit peripherals, so only the least significant byte
from the word contains the data.

Once the PXA270 microprocessor has serviced a PC/104 interrupt, the corresponding bit
in the PC104_IRQ register has to be cleared by writing a ‘1’ to it. Clearing the
corresponding bit in the PC104_IRQ register will bring GPIO17 level to logic ‘0’ and make
the interrupt logic ready for the next PC104 interrupt. When one or more other PC104
IRQs are asserted while the driver is processing PC104 IRQ, the new PC/104 IRQ
source has to wait for the current IRQ to be processed. This situation is shown in the
following diagram:
Delay:
250-375ns

Driver processing IRQ3

due to priority over IRQ6
Driver clears IRQ3 at source
and in PC104_IRQ register
PC104_IRQ6
PC104_IRQ4
There is a delay of 250-375ns between the de-assertion of the GPIO17 IRQ signal and
its new assertion due to the pending PC104 interrupt. This delay is introduced into the
ZEUS hardware implementation to accommodate for the minimum inactive time of GPIO
signals required by a PXA270 processor (154ns).

ZEUS user manual
Unsupported PC/104 interface features
The ZEUS does not support the following PC/104 bus features:
•
PC/104 IRQ9, IRQ14 and IRQ15 are not available.
•
DMA is not supported. Therefore, AEN signal is set to a constant logical zero.
•
Bus mastering is not supported. Therefore, do not connect any other master add-on
board to the ZEUS PC/104 interface.
•
Shared interrupts are not supported. Do not connect more than one add-on board to
the same interrupt signal line.
•
BALE signal is set to a constant logical one as the address is valid over the entire
bus cycle. Add-on PC/104 boards that implement transparent latch on address lines
LA17-LA23 are compatible with the ZEUS implementation of BALE.
•
The PXA270 PCMCIA memory controller does not support 8-bit memory read
accesses for common memory space.
•
The PXA270 PCMCIA memory controller does not support PC/104 MEMCS#
signalling, so there is no support for dynamic bus sizing.
Flat panel display
The PXA270 processor contains an integrated LCD display controller. It is capable of
supporting both colour and monochrome single- and dual-scan display modules. It
supports active (TFT) and passive (STN) LCD displays up to 800x600 pixels.
The PXA270 can drive displays with a resolution up to 800x600, but as the PXA270 has
a unified memory structure, the bandwidth to the application decreases significantly. If the
application makes significant use of memory, such as when video is on screen, you may
also experience FIFO under-runs causing the frame rates to drop or display image
disruption. Reducing the frame rate to the slowest speed possible gives the maximum
bandwidth to the application. The display quality for an 800x600 resolution LCD is
dependant on the compromises that can be made between the LCD refresh rate and the
application. The PXA270 is optimized for a 640x480 display resolution.
A full explanation of the graphics controller operation can be found in the Intel PXA27x
Processor Family Developer’s Manual included on the Development Kit CD.
The ZEUS-FPIF interface board allows the user to easily wire-up a panel using pin and
crimp style connectors (see page 114). Contact Eurotech Sales (see page 125) for
purchasing information. Alternatively, the display interface is connected to an LVDS
interface (see the section LVDS interface, page 44). This may be useful when driving
displays located more than 300mm (12") from the ZEUS.
The following tables provide a cross-reference between the flat panel data signals and
their function when configured for different displays.

LCD logic and backlight power
The display signals are +3.3V compatible. The ZEUS contains power control circuitry for
the flat panel logic supply and backlight supply. The flat panel logic is supplied with a
switched 3.3V (default) or 5V supply (for details see the section JP3 – LCD logic supply
selection, page 86). The backlight is supplied with a switched 5V supply for the inverter.
The power switches (TPS2033D) for flat panel logic and backlight have the currentlimiting (1.5A) and thermal protection features which eliminates the need for the fuses.
The PXA270 GPIO101 pin (LCDEN signal) controls the supply voltage to the LCD

ZEUS user manual
LCD backlight brightness control
GPIO16 of the PXA270 processor is used for backlight brightness control (signal PWM0
on the J14 connector). The control of the backlight brightness is dependent upon the type
of backlight inverter used with the display. Some inverters have a ‘DIM’ function, which
uses a logic level to choose between two levels of intensity. If this is the case then
GPIO16 (Alternative Function 0) is used to set this. Other inverters have an input suitable
for a pulse-width modulated signal or analogue voltage control. In this case GPIO16
should be configured as PWM0 (Alternative Function 2).
Signal PWM0 is also routed through a low-pass filter on the ZEUS to enable analogue
voltage control of backlight brightness (signal BRT_CTRL on connector J24 – Backlight
power - see page 84). The voltage range of BRT_CTRL is 0-2.5V.
STN bias voltage
The ZEUS provides a negative and a positive bias voltage for STN type displays (turned
on by the PXA270 GPIO101 pin). The negative and positive bias voltages are factory set
to -22V and +22V respectively. Pin connections for these can be found in the section J14
– LCD connector, page 77. Please contact Eurotech Technical Support (see page 125)
for details of other bias voltages.
Do not exceed 20mA load current.
LVDS interface
There is an optional Low-Voltage Differential Signalling (LVDS) interface available on the
ZEUS. LVDS combines high data rates with low power consumption. The benefits of
LVDS include low-voltage power supply compatibility, low noise generation, high noise
rejection and robust transmission signals.
The National Semiconductor transmitter DS90C363 is used to convert 16-bits of LCD
data signals into three LVDS data streams. A phase-locked transmit clock is transmitted
in parallel with the data streams over a fourth LVDS link. The LVDS signals are routed to
the connector J16. For the connector details see the section J16 – LVDS connector, page
78.
The LVDS transmitter is enabled using the signal LVDS_EN (GPIO21 on PXA270).

A Wolfson WM9712L AC’97 audio CODEC is used to support the audio features of the
ZEUS. Audio inputs supported by the WM9712L are stereo line in and a mono
microphone input.
The WM9712L provides a stereo line out that is amplified by a National Semiconductor
LM4880 250mW per channel power amplifier, suitable for driving an 8Ω load. The
WM9712L AC’97 codec may be turned off if it is not required. See the section Audio
power management, page 63, for details.

Touchscreen controller
The ZEUS supports 4-wire and 5-wire analogue resistive touchscreens using the
controller available within the Wolfson WM9712L audio CODEC. The touchscreen
controller supports the following functions:
•
X co-ordinate measurement.
•
Y co-ordinate measurement.
•
Pen down detection with programmable sensitivity.
•
Touch pressure measurement (4-wire touchscreen only).
The touchscreen can be used as a wake-up source for PXA270 from sleep mode.
The touchscreen interface is broken out on the header J1. For details see J1 –
Touchscreen connector, page 69.
USB
There are two USB host interfaces on the ZEUS. These comply with the Universal Serial
Bus Specification Rev. 1.1, supporting data transfer at full-speed (12Mbit/s) and lowspeed (1.5Mbit/s).
There are four signal lines associated with each USB channel: VBUS, DATA+, DATA-,
GND. The USB host ports are connected to a dual USB connector, type A (J8).
A USB power control switch controls the power and protects against short-circuit
conditions. If the USB voltage is short-circuited, or more than 500mA is drawn from either
supply, the switch turns the power supply off and automatically protects the device and
board. The VBUS power supply is derived from the ZEUS +5V supply. To switch the
VBUS1 and VBUS2 power on, use the PXA270 GPIO89 and GPIO22 respectively (set
them to logic ‘1’).
USB port 2 can be configured as a client port internally within the PXA270 USB
controller, and is connected to 5-pin header J10.
For details of connector pinouts, see the sections J8 – USB connector, page 73, and J10
– USB client header, page 74.
More information about the USB bus and the availability of particular USB peripherals
can be found at www.usb.org.
Host port 2 on J8 and client port on J10 can only be used one at a time. DO NOT
connect both devices at the same time.

Ethernet
The ZEUS SBC provides two 10/100-BaseTX interfaces with MAC and complies with
both the IEEE802.3u 10/100-BaseTX and the IEEE 802.3x full-duplex flow control
specifications.
Two single 10/100-BaseTX Ethernet controllers, Davicom DM9000A, are used to
implement Ethernet interfaces on ZEUS. DM9000A device provides an embedded PHY
and MAC and connects to 10/100-BaseTX magnetics. DM9000A also supports AUTOMDIX feature. Configuration data and MAC information are stored in an external serial
EEPROM (93LC46).
The DM9000A devices are connected to the PXA270 data bus (16-bit), and are memory
mapped. Connection to the ZEUS Ethernet ports is via dual RJ45 connector, J6, with
speed and link/activity status LEDs. For pin assignment and connector details, see J6 –
Ethernet connector, page 72.
The link/activity LED (yellow) is illuminated when a 10/100-BaseTX link is made, and
when there is Tx/Rx activity. The speed LED (green) is illuminated when 100MB/s speed
is selected.
Serial COM ports
There are seven serial communications ports available on the ZEUS. Three are provided
by the PXA270 and are used for the optional wireless modem, GPS and IEEE802.15.4 /
ZigBee ports.
There are four additional high-speed, 16550 compatible serial UARTs implemented by an
EXAR ST16C554Q Quad UART device. Two of these channels (COM1, COM2) can be
used as standard RS232 serial interfaces, COM3 can be configured as RS232 or
RS485/422, and COM4 can be configured as RS422 or RS485. The table below provides
a summary of the four additional serial ports.

Further details about the RS422 and RS485 interfaces are provided below.
RS422
The RS422 interface provides full-duplex communication. The signals available are TX+,
TX-, RX+, RX- and ground. The maximum cable length for an RS422 system is 1200m
(4000ft). It supports one transmitter and up to ten receivers.
RS485
This is a half-duplex interface that provides combined TX and RX signals (TX+/RX+ and
TX-/RX-). A ground connection is also required for this interface. The maximum cable
length for this interface is the same as RS422 - 1200m (4000ft), but RS485 supports up
to 32 transmitters and receivers on a single network. Only one transmitter should be
switched on at a time. The ZEUS uses the RTS# signal to control transmission. When
this signal is at logic 1, the driver is switched off and data can be received from other
devices. When the RTS# line is at logic 0, the driver is on. Any data transmitted from the
ZEUS is automatically echoed back to the receiver. This enables the serial
communications software to recognize that all data has been sent, and disable the
transmitter when required.

CAN bus
A Microchip MCP2515 CAN 2.0B protocol compatible controller and MCP2551
transceiver are used on the ZEUS to provide Controller Area Network (CAN) bus
connectivity. CAN is a high-integrity serial data communications bus for real-time
applications. It operates at data rates of up to 1 Mbit/s and has excellent error detection
capabilities. A 16MHz clock is supplied to the CAN controller.
The MCP2515 controller connects to the SPI serial interface of the PXA270 processor. A
MCP2551 transceiver is opto-isolated from the rest of the circuit (3.75kV isolation
voltage), but an external isolated 5V supply needs to be provided to supply the
transceiver and the opto-isolators. Alternatively, non-isolated operation is available
through a factory fit option. Contact Eurotech Technical Support (see page 125) for
details.
The CAN bus interface is broken out to the header J17. For connector details see the
section J17 – CAN bus, page 79.
Jumpers JP5, JP6 can be used to connect 62Ω termination resistors when the ZEUS is
at the end of the network. Split termination concept is used on ZEUS (see figure below).

Fast-mode devices are downward compatible and can communicate with standard-mode
devices in a 0 to 100KB/s I²C bus system. As standard-mode devices, however, are not
upward compatible, they should not be incorporated in a fast-mode I²C bus system as
they cannot follow the higher transfer rate and unpredictable states would occur.
The I²C interface does not support the hardware general call, 10-bit addressing,

Quick Capture camera interface
The Quick Capture camera interface is a component of Intel Quick Capture technology
which provides a connection between the PXA270 processor and a camera image
sensor. The Quick Capture interface is designed to work primarily with CMOS-type image
sensors and supports up to 4 Megapixel resolution. However, it may be possible to
connect some CCD-type image sensors to the PXA27x processor (PXA27x processor),
depending on a specific CCD sensor’s interface requirements.
The Quick Capture interface acquires data and control signals from the image sensor,
and performs the appropriate data formatting prior to routing the data to memory, using
direct memory access (DMA). A broad range of interface and signalling options provides
direct connection. The image sensor can provide raw data through a variety of parallel
and serial formats. For sensors that provide pre-processing capabilities, the Quick
Capture interface supports several formats for RGB and YCbCr colour space.
2
The Quick Capture interface signals are connected to the header J9. The I C interface is
available on the same header since most of the camera image sensors require an I2C
control interface. For I2C bus address map on the ZEUS, see the section I²C bus on the
previous page. For connector details, see the section J9 – Camera interface connector,
page 74.
External General purpose I/O
A Maxim MAX7313 I²C I/O Expander provides sixteen general purpose input/output lines
on the header J7. Each I/O port can be individually configured as either an open-drain
current-sinking output rated at 50mA with10K pull-up to 5V, or a logic input with transition
detection. The I/O Expander inputs are 5V tolerant.
The I/O Expander is addressable at I²C serial bus address 0x20 and is accessed in fastmode operation at 400 kbps. On power-up all control registers are reset and the
MAX7313 enters standby mode. Power-up status makes all ports into inputs, so the state
of all 17 ports (P0-P16) is logic high (through 10K pull-up to 5V).
See the section J7 – GPIO connector, page 73, for connector pinout and mating
connector details. The signals on J7 correspond to the pin names of the MAX7313
(P0-P15).

Temperature sensor
There is a Philips LM75A temperature sensor on the ZEUS. The LM75A is a temperatureto-digital converter using an on-chip band-gap temperature sensor and sigma-delta A-toD conversion technique. The device is also a thermal detector providing an overtemperature detection output (OVERTEMP signal on GPIO96 of PXA270). The accuracy
of LM75A is ±2 °C (at -25 °C to 100 °C), and ±3 °C (at -55 °C to 125 °C). LM75A is
connected to the I2C bus of PXA270 processor, and is accessible at I2C bus address
0x48.
JTAG and debug access
Debug access to the PXA270 processor is via the JTAG connector J5. A standard ARM
20-pin header is used for the JTAG interface. See J5 – JTAG connector, page 71, for
details.
Jumper JP7 needs to be inserted to enable the JTAG interface for PXA270 debug. See
section JP7 - JTAG Enable, page 88 for details.
The Macraigor Wiggler (see www.macraigor.com/wiggler.htm) and usb2Sprite (see
www.macraigor.com/usb2sprite.htm) probes have been used to debug the PXA270
processor on the ZEUS. There are many other debug tools that can be interfaced to the
ZEUS for access to the JTAG Interface of the PXA270 processor.
In addition to the PXA270, there are two CPLDs (XC9536XL-CS48 and
XC9572XL-CS48) in the JTAG chain on the ZEUS. The BSDL files can be found
on the www.xilinx.com web site.

Power and power management
Power supplies
The ZEUS is designed to operate from a single +5V±5% (4.75V to +5.25V) input or the
onboard 10V to 30V DC/DC PSU.
DC input voltage (10-30V)
DC input voltage (10-30V) is connected through a front panel locking DC jack J3 (see the
section J3 – Power connector (10-30V), page 70). When operating from the 10 to 30V
input, the 5V connector (J2) is NOT fitted. The input rails are protected from overcurrent,
overvoltage, undervoltage and reverse battery conditions, and include transient
suppression to achieve compatibility with vehicle power supplies. The on-board DC/DC
converter can provide a maximum current of 5A at 5V at a temperature range of 0-70°C
(32-158°F).
For vehicle-based applications, the supervisory circuit monitors the auxiliary ignition
supply input (Vig), and provides feedback of ignition status to the PXA270 (IG_FAIL
signal at GPIO115). If the Vig falls below 9.2V, IG_FAIL becomes logic ‘1’. This can be
used to instigate an orderly shutdown or to store ignition status data.
5V only operation
For 5V only operation, the ATX style connector J2 is used as the main power input for the
ZEUS. In this case, connector J3 and the entire DC/DC PSU circuit is depopulated. The
power connector J2 has a +12V connection too, but it is not required for the ZEUS under
normal operation. It can be used to supply +12V to the PC/104 stack if required. For
details of the 5V power connector see the section J2 – Power connector (5V option),
page 70. Contact Eurotech Sales (see page 125) for details.
If a CompactFlash and an LCD display are used, ensure the total current
requirement on the 3.3V rail does not exceed 900mA. Please check the
datasheets of the devices you are using.

VCC_PER, VCC_MODEM and +3V3 supply rails are controlled by SYS_EN signal of the
PXA270. They are switched off when PXA270 is in deep-sleep mode.
VCC_PER rail is also monitored, and reset will be generated to the PC/104 interface if
the voltage falls below 4.63V. This can also generate an interrupt on pin GPIO20 of the
PXA270.
Power management IC
The Linear Technology device LTC3445 is used to provide the power supply for the
PXA270. It is specifically designed for the PXA27x family of microprocessors.
The LTC3445 contains a high efficiency buck regulator (VCC_CORE), two LDO
regulators (VCC_PLL, VCC_SRAM), a PowerPath controller and an I2C interface. The
buck regulator has a 6-bit programmable output range of 0.85V to 1.55V. The buck
regulator uses either a constant frequency of 1.5MHz, or a spread spectrum switching
frequency. Using the spread spectrum option gives a lower noise regulated output, as
well as low noise at the input. In addition, the regulated output voltage slew rate is
programmable via the Power Management I2C interface of the PXA270.

respectively. Reliable operation below these minimum voltages cannot be
guaranteed.
Processor power management
First available in the PXA270 processor, Wireless Intel SpeedStep Technology
dynamically adjusts the power and performance of the processor based on CPU
demand. This can result in a significant decrease in power consumption.
In addition to the capabilities of Intel Dynamic Voltage Management, the Intel XScale
micro architecture of the PXA27x family incorporates three new low power states. These
are deep idle, standby and deep sleep. It is possible to change both voltage and
frequency on the fly by intelligently switching the processor into the various low power
modes. This saves additional power while still providing the necessary performance to
run rich applications.
Wireless Intel SpeedStep technology includes the following features:
58
•
Five reset sources: power-on, hardware, watchdog, GPIO and exit from sleep and
deep-sleep modes (sleep-exit).
•
Multiple clock-speed controls to adjust frequency, including frequency change, turbo
mode, half-turbo mode, fast-bus mode, memory clock, 13M mode, A-bit mode and
AC ’97.
•
Switchable clock source.
•
Functional-unit clock gating.
•
Programmable frequency-change capability.
•
One normal-operation power mode (run mode) and five low power modes to control
power consumption (idle, deep-idle, standby, sleep and deep-sleep modes).
•
Programmable I2C-based external regulator interface to support changing dynamic
core voltage, frequency change and power mode coupling.

Wake-up sources
The PXA270 offers two sleep modes:
•
Sleep mode offers lower power consumption by switching off most internal units. There
is no activity inside the processor, except for the units programmed to retain their state
in the PSLR register, the real time clock and the clocks and power manager. Because
internal activity has stopped, recovery from sleep mode must occur through an external
or internal real time clock event. External wake-up sources are GPIO<n> edge detects
(they are listed in the section PXA270 GPIO pin assignments, page 22).

Deep-sleep mode offers the lowest power consumption by powering most units off.
There is no activity inside the processor, except for the real time clock (RTC) and the
clocks and power manager. Because internal activity has stopped, recovery from deepsleep mode must be through an external event or an RTC event. In deep-sleep mode,
all the PXA270 power supplies (VCC_CORE, VCC_SRAM, VCC_PLL, VCC_IO
excluding VCC_BATT) are powered off for minimized power consumption. On the
ZEUS, the main +3.3V rail supplies the VCC_IO power domain of the PXA270. Since
the +3.3V supply is switched off in deep-sleep mode, all the on-board peripherals are
powered off and it is not possible to use external wake-up sources. In this situation,
recovery from deep-sleep mode must be through an internal RTC event.
For more information on PXA270 power management, see section 3.6 in the Intel
PXA27x Processor Family Developer’s Manual, included on the Development Kit CD.

CompactFlash power management
The power supply to the CompactFlash interface is controlled via software, and supports
hot swap card insertion and CompactFlash power down states. GPIO97 on the PXA270
(signal CF_PWEN) is used to control the power supply switch. Setting this line to logic ‘0’
switches off the power to the CompactFlash interface. The current-limiting (1A) and
thermal protection features of the power switch eliminate the need for the fuse. The
power supply to the CompactFlash is derived from 3.3V supply.

Wireless modem power management
The power supply to the wireless modem interface (VCC_MODEM) is controlled by
SYS_EN signal of the PXA270, and is switched off when PXA270 is in deep-sleep mode.
The current-limiting (2A) and thermal protection features of the power switch eliminate
the need for the fuse. VCC_MODEM power supply is derived from the ZEUS +5V supply.
GSM_ON and GPS_ON control signals are provided on the ZEUS Modem connector
(J23). They are controlled by on-board GPIO expander (see On-Board GPIO expanders
pin assignments, page 29). For details on how to use these signals, and other power
management features of the specific wireless and GPS devices, please consult the
datasheet of the device used.
USB power management
A USB power control switch controls the power, and protects against short-circuit and
over-current conditions, on USB host ports.
If the USB voltage VBUSx is short-circuited, or more than 500mA is drawn from any
VBUSx supply, the switch turns off the power supply and protects the device and board
automatically. The VBUSx power supplies are derived from the ZEUS +5V supply.

Power and power management
Ethernet power management
The Ethernet controllers (Davicom DM9000A) incorporate a number of features to
maintain the lowest power consumption.
The device can be put into a power-reduced mode by setting the PHY control register bit
16.4. In power-reduced mode, the device transmits the fast link pulses with minimum
power consumption. It also monitors the media for the presence of a valid signal and, if
detected, the device automatically wakes up and resumes normal operation. The power
consumption in power-reduced mode (without the cable) is 31mA.
The PHY can be put into a sleep mode by setting the PHY control register bit 16.1, which
powers down all the circuits except the oscillator and clock generator circuit.
The PHY can be put into a power-down mode by setting the PHY control register bit 0.11,
which disables all transmit and receive functions but not access to PHY registers. The
power consumption in power-down mode is 63mW. The system clock can be turned off,
by using the SCCR register (bit 0) of DM9000A, to further reduce the power consumption
to 22mW.
For more information about power management, refer to the DM9000A datasheet on the
Development Kit CD.
Audio power management
The audio CODEC (Wolfson WM9712L) supports the standard power down control
register defined by AC’97 standard (26h). In addition, the individual sections of the chip
can be powered down through register 24h. Significant power savings can be achieved
by disabling parts of WM9712L that are not used.
Shutting down all the clocks and digital and analogue sections can reduce WM9712L
consumption down to near zero (1.65μW).
For more information about power management, refer to the WM9712L datasheet on the
Development Kit CD.
LVDS power management
If not used, the DS90C363 LVDS transmitter can be placed in power down mode by
applying a low-level to GPIO21 of PXA270 (signal LVDS_EN). The power consumption in
power down mode is 180μW.

CAN bus power management
The Microchip MCP2515 CAN bus controller has an internal sleep mode that is used to
minimize the current consumption of the device. The SPI interface remains active for
reading even when the MCP2515 is in sleep mode, allowing access to all registers. To
enter sleep mode, the mode request bits are set in the CANCTRL register
(REQOP<2:0>).
When in internal sleep mode, the wake-up interrupt is still active (if enabled) which
means that upon detecting activity on the bus, it can be used as a wake-up source for
PXA270. When in sleep mode, the MCP2515 stops its internal oscillator. The MCP2515
will wake up when bus activity occurs, or when the PXA270 sets the CANINTF.WAKIF bit
to ‘generate’ a wake-up attempt, via the SPI interface. The power consumption in sleep
mode is near zero (15μW).
The transceiver device (MCP2551) may be placed in sleep mode by applying a high-level
to GPIO2 of Expander 2 (I2C address 0x22, signal CAN_SHDN). In sleep mode, the
transmitter is switched off and the receiver operates at a lower current. The receive pin
on the controller side (RXD) is still functional but will operate at a slower rate. The power
consumption in sleep mode is 1.8mW.

For more information about power management, refer to the MCP2515 and MCP2551

Clock generator power management
Two clock synthesizer IC’s (Cypress CY22381) can be placed in low power mode by
shutting down the clock outputs in case the corresponding interfaces are not used. You
can do this by applying a low-level to the GPIO0 pin on the Expander 2 (I2C address
0x22, signal CLK_SHDOWN#). The following clocks are affected:
•
ST16C554Q UART 14.7456MHz clock.
•
Ethernet PHY 25MHz clock.
•
PC/104 8MHz and 14MHz clocks.
•
CAN bus 16MHz clock.
•
Audio clock 24.576MHz.
This can reduce the power consumption of each clock generator IC down to 66 μW.

RS232 transceivers can be placed in low power mode in case they are not used. This
can reduce the power consumption of each RS232 transceiver down to 33 μW. GPIO
pins 3 and 4 of Expander 2 (I2C address 0x22) are used to shut down COM1 and COM2.
GPIO pin 1 of Expander 1 (I2C address 0x21) is used to shut down COM3.

Temperature sensor power management
The LM75A device can be set to operate in two modes: normal or shut-down. In normal
operating mode, the temp-to-digital conversion is executed every 100ms and the Temp
register is updated at the end of each conversion. In shut-down mode, the device
becomes idle, data conversion is disabled and the Temp register holds the latest result.
However, the device I2C interface is still active and register write/ read operation can be
performed. The device operating mode is controllable by programming bit B0 of the
configuration register. The temperature conversion is initiated when the device is
powered-up or put back into normal mode from shut-down. The power consumption in
shut-down mode is near zero (11.5μW).
For more information about power management, refer to the LM75A datasheet on the
Development Kit CD.
I/O expander power management
When the serial I2C interface is idle and the PWM intensity control is unused, the
MAX7313 automatically enters standby mode. If the PWM intensity control is used, the
operating current is slightly higher because the internal PWM oscillator is running. The
power consumption in standby mode (with PWM disabled) is near zero (4μW).
Configuration PROM power management
When the serial I2C interface is idle the 24AA01 automatically enters standby mode. The
power consumption in standby mode is near zero (3.3μW).

When mounting the ZEUS use only M3 (metric) or 4-40 (Imperial) screws.
The mounting pad is 6.35mm (0.25") and the hole is 3.175mm (0.125"), so
ensure any washers fitted are smaller than the pad.
Using oversized screws and washers, or tooth locking washers, can cause
short circuits and over-voltage conditions.
We recommend that you use a Loctite screw thread lock or a similar product
over tooth locking washers.
