1. Keith & Koep GmbH offers two kinds of Trizeps modules. First one, in the following
called „Trizeps I“, based on the Intel StrongARM SA-1110 Microprocessor. The second
one, called „Trizeps II“, based on the PXA250 Microprocessor. Both processors work
very fast (270 Dhrystone 2.1 MIPS @ 206MHz for Trizeps I and 480 Dhrystone 2.1 MIPS
@ 400MHz for Trizeps II) and need very low power. Both Trizeps modules include also
the Philips UCB 1x00 (a single chip, integrated mixed signal audio and telecom codec).
The single channel audio codec is designed for direct connection of a microphone and a
speaker. The incorporated analog to digital converter and the touch screen interface provides complete control and read-out of an 4 wire resistive touch screen. The Trizeps offers
up to 16MByte Flash memory and up to 64MByte SDRAM.

Keith & Koep GmbH Preface
2.0 Preface
2.1 Getting started
The MT6N board is designed as a motherboard for Trizeps I and Trizeps II. The
first part of this chapter gives a physical description of the board and the second part
describes:
1. How to unpack the board and how to make a visual inspection.
2. How to power up the board for the first time.
3. How to connect the board to a host system
2.1.1 Physical description
The physical layout of the board is shown in figure 6 on page 23 (You’ll find details
on the last page). The dimensions of the board are 223 x 134 mm (LxW). You can
find all measures at figure 8 on page 49.
There are a number of header blocks on the board that accept 2-pin jumpers, allowing the board to be configured in different ways. Due to further header blocks it is
possible to connect an LCD-display with touch screen. A serial connection to a host
system is possible by using one of the RS232 interfaces. Furthermore the board contains an JTAG-interface for programming the Trizeps.
2.1.2 Unpacking the board
The MT6N contains electronic components that are susceptible to electrostatic discharge (static electricity). To avoid electrostatic damage the board is supplied in an
antistatic bag. When handling the card, risk of damage can be diminished by taking
a few simple precautions:
1. Do not remove the card from the bag unless you are working on an antistatic,
grounded surface and wearing an grounded antistatic wrist strap.
2. Keep the antistatic bag the card was supplied in; if you remove the card from a
system, store it in the bag.
Normally MT6N is supplied with a Trizeps in the SODIMM-socket. If the
SODIMM is not fitted with Trizeps when you receive your board, follow the next
instructions:
1. Slide the Trizeps into the socket taking account of the polarity mark. Do not
touch the gold contacts. You can see that there is a polarization mark cut in the
Trizeps; this ensures that the Trizeps is adjusted correctly. Put the Trizeps modul
carefully at an angle of about 30 degrees into the socket.
2. Support the underside of the board and push the Trizeps down into the socket. It
should click into its place with a gentle click.
Before you install and power up your MT6, you should perform a short visual
inspection:
1. Inspect the card for physical damage.
2. Ensure that each of the 2-pin jumpers is pushed down firmly onto its mounting
posts. If you move any of the jumpers, refer to Appendix A to ensure they are
replaced correctly.

Keith & Koep GmbH Functional specification
2.1.3 Powering up the first time
Use Appendix A to ensure the jumpers are set appropriately. If you need more
details on how to install the card or attach power supply, refer to Appendix A, too.
2.1.4 How to connect the board to host system
Use an RS232 null-modem cable to attach the serial interface on the board to an
RS232 port on a terminal or terminal emulator. For example, you could connect it to
a PC running Windows and use the Windows Terminal or Hyperterminal application. Configure the terminal to operate at 38 kbaud, 8-bit data, 1 stop bit, no parity,
no flow control. If you need more details on choosing an appropriate cable, refer to
appendix A.

3.1 Trizeps
The MT6 board is fitted out either with the Trizeps I or the Trizeps II module.
3.1.1 Trizeps I
The Trizeps board is based on the Intel StrongArm SA-1110 Microprocessor - a
highly integrated communications microcontroller that incorporates a 32-bit StrongArm Risc Processor core, system support logic, multiple communication channels,
an LCD controller, a memory and PCMCIA controller, and general-purpose I/O
ports.The SA-1110 is working very fast (150 Dhrystone 2.1 MIPS @ 133 MHz or
235 Dhrystone 2.1 MIPS @ 206 MHz) and needs very low power. Trizeps includes
also the Philips UCB 1200 (a single chip, integrated mixed signal audio and telecom
codec). The single channel audio codec is designed for direct connection of a microphone and a speaker. The built-in telecom codec can directly be connected to a
DAA and supports high speed modem protocols. The incorporated analog to digital
converter and the touch screen interface provides complete control and read-out of
an 4 wire resistive touch screen.
3.1.2 Trizeps II
The Trizeps II Module is based on the Intel® XScale™ core-based CPU (200, 300
and 400 MHz) PXA250 - ARM Architecture v.5TE compliant and application code
compatible with Intel® SA-1110 processor which is used on the Trizeps I module.
The CPU based on Intel® Superpipelined RISC technology utilizing advanced Intel
0.18µ process for high core speeds at low power (480K Dhrystone 2.1 per second
@ 400 MHz). Some features of the XScale: Integrated memory and PCMCIA/CompactFlash Controller with 100MHz Memory Bus, 16-bit or 32-bit ROM/Flash/
SRAM six banks, 16-bit or 32-bit SDRAM; System Control Module includes 17
dedicated general-purpose interruptible I/O ports, real-time clock, watchdog and
interval timers, power management controller, interrupt and reset controller, LCD
controller and two on-chip oscillators. Trizeps-II includes also the Philips UCB
1400, on a single chip it combines audio codec functions, a touch-screen controller
and power management interfaces. The incorporated A/D converter and the touch
screen interface provides complete control and read-out of a 4 wire resistive touch
screen.
3.2 Serial EEPROM (optional)
MT6N provides a serial EEPROM (X24C16- Xicor) to be used as a non-volatile
memory. It has a size of 16KBit and it is internal organized as 2048 x 8. The
X24C16 offers a serial interface and a software protocol allowing operation on a
simple two wire bus with I
of SA-1110). The EEPROM is optional and usually not placed.

3.3.1 PCMCIA
In the past memory expansion cards (specification 1.0) of the size of check cards
had just the purpose of providing memory. With the today generally valid specification 2.0 much of I/O units can be placed in a PCMCIA-slot. This includes for example SCSI-adaptation, Ethernet-Card or modem cards.
The PCMCIA-adaption connector on the board is designed on the basis of specification 2.0 (representative of this specification is the Personal Computer Memory
Card International Association)
The adjustment of the supply voltage and the programming voltage of the PCMCIA-card is to be effected by the Board Control Register.
3.3.2 CompactFlash
CompactFlash is a very small removable mass storage device. It provides complete
PCMCIA-ATA functionality and compatibility plus TrueIDE functionality compatible with ATA/ATAPI-4. At 43mm (1.7“) x 36mm (1.4“) x 3.3mm (0.13“), the
device’s thickness is less than one-half of a current PCMCIA Type II card. It is actually one-fourth the volume of a PCMCIA card. Compared to a 68-pin PCMCIA
card, a CompactFlash card has 50 pins (the connector is similar to the PCMCIA
card) but still conforms to PCMCIA-ATA specs. CompactFlash cards are designed
with flash technology, a non-volatile storage solution that does not require a battery
to retain data indefinitely. CompactFlash storage products are solid state, meaning
MT6N (MT606) 6 von 49
Keith & Koep GmbH Functional specification
they contain no moving parts, and provide users with much greater protection of
their data than conventional magnetic disk drives.
3.4 Board Control Register BCR
The MT6N board requires additional GPIO output functions, which are implemented in the Board Control Register (BCR) to control the Compact Flash, PCMCIA, display and something else.

With setting the data bus D04 the display control signal L_DISP can be switched.
The important thing about that is the power on/off timing of the display. Usually the
correct sequence is as followed:
1. Power Supply
2. Input signal
3. Contrast voltage
4. Display control signal L_DISP
If you use another display as delivered from Keith & Koep you should test the correctness of the power on/off sequences.
Resetting the data bus D05 switches the address and control-signals of the PCMCIA-buffer.
With setting the data bus D06 the serial interface driver is switched on.
With setting the data bus D07 a reset-signal is sent to the PCMCIA-slot.

3.5 Real Time Clock (RTC)
MT6N contains a Low-Power RTC from Philips, called PCF8593. This chip uses
the same two wire bus as the serial EEPROM, which is described in figure 2 on
page 5.

The RTC is either supplied from the onboard battery or from an external battery.
3.6 JTAG interfaces
The SA-1110 contains a JTAG port that allows test access to the I/O pins of the
device. The JTAG port is designed as a 10-pin header connector.
High order

With a second JTAG interface program the CPLDs on board. It is designed as a 6pin header.
3.7 Reset
There are two sources of reset on the MT6N:
1. Power-on Reset
2. Reset from the watchdog timer
Power-on reset is generated automatically when power is applied to the board. It
can also be initiated by a push button switch attached to a 2-pole 0.1-inch pitch connector on the board.
Resets generated by any of these methods are equivalent and indistinguishable.
3.8 Power Supply
Power supply is possible on several ways:
First: The Power supply of MT6N is accessible by a power connector by Phoenix
with part number PSC 1,5/3-M. Pin 1 is the positive one (+24V) and Pin 3 is
Ground.
Second: It is also possible to supply MT6N by an optional PCB where the TTL I/O
ports are electrically isolated. More information: http://www.keith-koep.com.
Third: Supply through a 2-pin connector by Phoenix, which is optional and usually
not placed.
MT6N (MT606) 9 von 49
Keith & Koep GmbH Functional specification
3.9 Power generation on board
+12V are generated from the +24V power supply using a DC-DC converter. This
voltage is just needed for some PCMCIA cards and for some kinds of backlight
inverter of the display.
The power supplies +5V and +3V3 are generated from the +12V power by two further DC-DC converters. The +5V are used by PCMCIA or CompactFlash cards,
CAN and for backlight inverter. The +3V3 are used by Trizeps, Ethernet, PCMCIA
or CompactFlash cards, serial interfaces and something else.
3.10 GPIO
Both (Trizeps I and Trizeps II) modules put GPIOs at free disposal.
3.10.1 GPIO (Trizeps I)
The SA-1110 provides 28 general purpose I/O port pins for use in generating and
capturing application specific input and output signals. Each pin is programmable
as an input or output and as an interrupt source. Most GPIO pins have an alternate
function which can be invoked to enable additional functionality within the SA-
1110. If a GPIO is used for this alternate function it cannot be used as a GPIO at the
same time. The table below shows each GPIO pin with the using on MT6N and its
corresponding alternate function.

3.10.2 GPIO (Trizeps II)
The PXA250 processor enables and controls its 81 general purpose I/O (GPIO) pins
through the use of 27 registers which configure the pin direction (input or output),
pin function, pin state (outputs only), pin level detection (inputs only), and selection
of alternate functions. The PXA250 processor provides 81 GPIO pins for use in
generating and capturing application specific input and output signals. Each pin can
be programmed as either an input or output.When programmed to be an input, a
GPIO can also serve as an interrupt source. If a GPIO is used for it alternate function it cannot be used as a GPIO at the same time. The table below shows each
GPIO pin with the using on MT6N and its corresponding alternate function.

3.11 Ethernet
The Ethernet Controller (LAN91C96 by SMSC) on the MT6N board supports the
IEEE 802.3 (ANSI 8802-3) Ethernet Standards. It is connected to a 10 Base-T filter
module. The Ethernet connector is of the type RJ45. The controller in the configuration of MT6N provides:
• 6K Bytes of On-Chip RAM
• Support of enhanced transmit queue management
• Direct interface to ISA buses with no wait states
• Fast access time (40ns)
• Pipelined data path
• Integrated 10Base-T Transceiver functions:
•Driver and receiver

• Two direct driven LEDs for diagnostics (transmit / receive indication)
3.12 Serial ports
The MT6 provides four kinds of serial ports:
• USB
• UART
• IrDA
• SPI
3.12.1 Serial port 0 - USB Device Controller
Serial port 0 is an universal serial bus device controller (UDC) that supports three
endpoints and can operate half-duplex at a baud rate of 12 Mbps (slave only, not a
host or hub controller).The UDC is USB-compliant and supports all standard device
requests is issued by the host. The external pins dedicated to this interface are
UDC+ and UDC-. The USB protocol uses differential signalling between the two
pins for half-duplex data transmission. A 1.5 KOhm pull-up resistor is connected to
the USB cable’s D+ signal to pull the UDC+ pin high when not driven. This signifies the UDC is a high-speed, 12 Mbps device and provides the correct polarity for
data transmission.
Serial port 0 is accessible by an SL1-4 (four pin header). However, the user should
refer to the Universal Serial Bus Specification, Revision 1.0
of the USB protocol and its operation.
3.12.2 Serial port 1 - UART
Serial port 1 is configured as an universal asynchronous receiver / transmitter
(UART) serial controller. A Maxim MAX3223 RS232 transceiver is used to manage the level conversion and line interface. The device has a power saving auto-

matic shutdown that powers down the chip if no valid RS232 levels are detected.
The component may also be forced off by the FORCEON signal. Serial port 1 is
accessible by the female serial port connector J18 (10-pin header). The external pins
dedicated to this interface are TXD1 and RXD1. Further GPIO 12 and 13 are used
as hand-shake signals RTS and CTS.
For the communication between the PC (DB9 male) and the MT6 a serial extension
cable is needed. Therefore the serial port J18 (10 pin header) is to be connected with
a short flat cable to a DB9 female connector (see figure 7 on page 36).
3.12.3 Serial port 2 - Infrared communications port
The infrared communications port (ICP) operates at half-duplex and provides direct
connection to commercially available Infrared Data Association (IrDA) compliant
LED transceivers. The ICP supports both the original IrDA standard with speeds up
to 115.2 Kbps as well as the newer 4-Mbps standard. Both standards use different
bit encoding techniques and serial packet formats. Low-speed IrDA transmission
uses the Hewlett-Packard Serial Infrared standard (HP-SIR) for bit encoding and an
UART as the serial engine; high-speed uses Four-Position Pulse Modulation
(4PPM) and a specialized serial packet protocol developed expressly for IrDA
transmission. Serial port 2 is accessible by a 10-pin header. The external pins dedicated to the ICP are TXD2 and RXD2.

Alternately you can use serial port 2 as an UART.
3.12.4 Serial port 3 - UART
Serial port 3 is configured as an universal asynchronous receiver / transmitter
(UART) serial controller. A Maxim MAX3243 RS232 transceiver is used to
manage the level conversion and line interface. The device has a power saving automatic shutdown that powers down the chip if no valid RS232 levels are detected.
The component may also be forced off by the FORCEON signal. Serial port 3 is
accessible by the male serial port connector J12 (DSUB9M). This port provides
RTS, CTS, DSR, DTR and DCD modem signals to support a serial IO port PC synchronous application.

3.12.5 Serial port 4 - SSP
The synchronous serial port (SSP) of the SA-1110 is used to interface to a variety of
analog-to-digital converters, audio and telecom codecs, memory chips, and keypad
controllers as well as other miscellaneous serial devices. The SSP supports the
National Microwire and Texas Instruments synchronous serial protocols as well as a
subset of the Motorola serial peripheral interface (SPI) protocol. Serial port 4 controls full-duplex synchronous serial transfer between the SA-1110 and off-chip
devices. The SSP functions as a master only and communicates to the off-chip slave
device by driving a serial bit rate clock ranging from 7.2 KHz to 1.8432 MHz along
with a frame synchronisation pulse to denote the start of each frame transfer, and
supports any data format between 4 and 16 bits. The external pins dedicated to this
interface are GPIO 10 to 13.

3.13 CAN interface
The CAN (Controller Area Network) is a serial bus system especially suited for networking “intelligent“ devices as well as sensors and actuators within a system or
subsystem. MT6 uses the SJA1000, a stand-alone CAN controller made by Philips.
It is used within automotive and general industrial environments. SJA1000 is the
successor of the PCA82C200 CAN controller (BasicCAN) from Philips Semiconductors. Additionally, a new mode of operation is implemented (PeliCAN) which
supports the CAN 2.0B protocol specification with several new features.
This controller offers the following features:
• PIN and Electrical compatibility to the PCA82C200 stand-alone CAN controller
• PCA82C200 mode (BasicCan mode is default)
• Extended receive buffer (64-byte FIFO)
• CAN 2.0B protocol compatibility
• Supports 11-bit identifier as well as 29-bit identifier
• Bit rates up to 1Mbits/s
• PeliCAN mode extensions:
•Error counters with read/write access
•Programmable error warning limit
•Last error code register
•Error interrupt for each CAN-bus error
•Arbitration lost interrupt with detailed bit position
•Single-shot transmission (no re-transmission)
•Listen only mode (no acknowledge, no active error flags)
•Hot plugging support (software driven bit rate detection)
•Acceptance filter extension (4-byte code, 4-byte mask)
•Reception of ’own’ messages (self reception request)
To use the can interface, please refer to the pinout description of the can connector
(J3 DB9 female) in table 12 on page 25.
3.14 TTL I/O
MT6 offers 16 TTL Inputs and 16 TTL Outputs. There are 2 I/O connectors called
J15 and J16 on the board. Both connectors comprise each 8 TTL Input ports and 8
TTL Output ports. The pinout is shown in table 24 on page 33 and table 25 on
page 34. The output signals (OUTPUT[00:15]) correspond with dataline signals
D[00:15], which are switched by a CPLD. They will be selected by addressing
0x19800000 (\CS_IO_OUT and \CS_IO_IN). The Inputs can be read as follows:
read = *(short *) ADR
The Outputs can be written as follows:
*(short *) portadr = value
Keith & Koep GmbH offers an optional circuit board with electrically isolated
ports, one which can be placed directly on J15 and another one that will be connected by a flat cable to J16. With this board it is possible to provide +24V for the
MT6N (MT606) 17 von 49
Keith & Koep GmbH Functional specification
MT6. You’ll find more information about the I/O board on our homepage
(www.keith-koep.com/trizeps.html)
3.15 Audio In/Out
The Trizeps board includes a single chip integrated mixed signal audio and telecom
codec (Philips UCB 1200). JJ2 and JJ3 on the MT6 give access to the speaker and
microphone signals. The pinout of JJ2 is shown in table 34 on page 39 and of JJ3 in
table 35 on page 39.
From MT6 Version 5 the board can be fitted out with an audio stereo connector.
3.16 Display connector and 4 wire Touch Panel
The SA-1110 on the Trizeps offers a 16 bit LCD-controller. The audio and telecom
codec (see chapter 3.15, "Audio In/Out" on page 18) provides also a 4 wire touch
screen interface. The relevant signals are accessible at J14 see table 23 on page 32.
The contrast voltage can be adjusted by an Digitally-Controlled Potentiometer by
Xicor. The device consists of a resistor array, wiper switches, a control section, and
nonvolatile memory. The wiper position is controlled by a three-wire interface.
The potentiometer is implemented by a resistor array composed of 99 resistive elements and a wiper switching network. Between each element and at either end are
tap points accessible to the wiper terminal. The position of the wiper element is controlled by the CS, U/D, and INC inputs. The position of the wiper can be stored in
nonvolatile memory and then be recalled upon a subsequent power-up operation.
