2.1 Block Diagram
The GR-UT699 board provides the electrical functions and interfaces as represented in the
block diagram, Figure 2-1.
Figure 2-1: Block Diagram of GR-UT699 board
The Main PCB is of standard Double Eurocard format (233.35 x 160mm) and, in principle,
could be used 'stand-alone' on the bench-top simply using an external +5V power supply.
The board is fitted with a Compact PC front panel, and is compatible with mounting in a 6U
Compact PC rack.
2.2 UT699 A IC
The UT699RH ASC is packaged in a 352-pin Ceramic Quad Flatpack, and is soldered in to
the PCB.
Details of the interfaces, operation and programming of the UT699 AS C is given in the

2.3 Memory
The memory configuration installed on the board is shown in the figure below comprising of:
•80Mbit of SRAM memory, organised as 1 banks x 2Mword x 40 bits wide
(a second SRAM bank can be installed on the PCB, but is not fitted as standard)
•128Mbit of Flash PROM, organised as 1 bank x 4 Mword x 32 bits wide)
•D L 32 pin socket to allow 1Mbit of EEPROM organised as 1 bank x 128kByte x 8
bits wide) to be installed
Additionally, in order to allow users to install alternative memory configurations or devices, all
the signals of the memory interface are connected to memory expansion connectors. The
expansion connectors allow mezzanine boards to be added similar to those developed for
the existing GR-CPCI development boards.

User Manual
2.3.1 RAM
The GR-UT699 board is laid out with two SRAM memory banks but only has one bank
mounted as standard. Each bank is made up of five CY7C1069AV33. These devices are
16Mbit (2Mbyte x 8 bit devices with 10 or 12 ns access times.
The five devices provide (32 + 8) bit wide SRAM memory paths allowing EDAC operation.
These memory banks are mapped as RAMBANK0 and RAMBANK1.
n case the user wishes to disable the on board memory, this can be done by removing the
jumpers JP5 on the PCB.
2.3.2 FLA H
The GR-UT699 board has mounted as standard one FLASH memory bank, made up of two
ntel JS28F640J3 FLASH devices. These devices are 64Mbit (8Mbyte x 16 bit devices),
typically with 90ns access times. The data bus width to the Flash memory is 32 bits wide.
Note that, the PROM width and PROM EDAC conditions are set by the state of the
GP O[2..0] pins at power up of the Processor. Therefore the GP O[2..0] D P switches on the
PCB must be appropriately set for the correct operation of the PROM memory at start up of
the processor. For information on the GP O[2..0] settings refer to the Memory Configuration
documentation in the Leon3 User Manual, or RD-3.
2.3.3 EEPROM
The GR-UT699 board additionally has a D P32 socket suitable for mounting an EEPROM
device. The data bus width to the EEPROM device is 8 bits wide.
This socket is suitable for mounting an EEPROM device of the type AT28LV010, or
compatible, in D P32 package. The AT28LV010 is an ATMEL EEPROM, of 1Mbit capacity
organised as 128kByte x 8 bits.
Jumpers are provided to enable the user to select either the FLASH PROM device or the
EEPROM to operate as the ROMBANK0 device which appears at the initial memory location
of 0x00000000.
2.3.4 MEMORY EXPAN ION CONNECTOR
Access to the memory signals is provided by the connectors J9 and J11. This enables uses
to conceive their own mezzanine boards and functions. Please see section.2.12.5
2.4 CAN Interface
The board provides the electrical interfaces for two CAN bus interfaces, as represented in
the block diagram, Figure 2-4.
The CAN bus transceiver C's on this board are SN65HVD230 devices from Texas
nstruments which operate from a single +3.3V power supply.
The connector interfaces are male DSUB-9 connectors adhering to the standard pin-out for
this type of interface (ref. Table 4-6 And Table 4-5).

User Manual
2.4.1 Configuration of Bus Termination
The CAN interfaces on the board can be configured for either end node or stub-node
operation by means of the jumpers JP3 and JP4 for interface 1 and 2 respectively, as shown
in Figure 2-5.
For normal end-node termination with a nominal 120 Ohm insert jumpers in position 1-3.
However, if a split termination is desired (if required for improved EMC performance), insert
the jumpers in positions 1-2 and 3-4.
For stub nodes, if termination is not required, do not install any jumpers.

2.4.2 Configuration of lew Rate
The SN65HVD230 transceiver device used on the board has the facility to set the device into
STANDBY mode, by connecting an active high external signal to pin 8 of the device (refer to
the device data sheet). However, on this board this is tied to permanently 'low' to enable the
CAN bus Transceivers.
A further feature provided by the SN65HVD230 device is the capability to adjust the
transceiver slew rate. This can be done by modifying the values of resistors connected to pin
8 of the transceivers.
The default value of 0 ohms is compatible with 1Mbps operation.
From the data sheet the following resistor values give the following slew rates:
10kOhm => 15V/us
100kOhm => 2V/us
2.5 pacewire (LVD ) Interfaces
The UT699 AS C provides four Spacewire interfaces which are routed to the front panel of
the board.
2.5.1 PW interface circuit
Each Spacewire interface consists of 4 LVDS differential pairs (2 input pairs and 2 output
pairs), as shown in the figure below. As the Spacewire interface to the UT699 AS C is
LVTTL (3.3V logic), LVDS driver and receiver circuits are required on the PCB to interface
between the AS C and the external interface.
The PCB traces for the LVDS signals on the GR-UT699 board are laid out with 100-Ohm
differential impedance design rules and matched trace lengths.
100 Ohm Termination resistors for the LVDS receiver signals are mounted on the board
close to the receiver.

15 GR-UT699 Development Board
User Manual
The pin out and connector types for these Spacewire interfaces conform to the Spacewire
standard, as shown in Figure 2-6.
The inner shield pin (pin3 of the connector) is connected to DGND via a Zero-ohm resistor.
2.5.2 PWCLK
Configuration options on the board (jumpers, crystal socket and SMA coaxial connector)
allow this Spacewire clock to be provided from the following sources:
•Dedicated SPWCLK oscillator (if appropriate Oscillator X3 is mounted in socket and
jumper J17 is not installed)
•Main processor oscillator X1(if jumper J17 is installed)
•External clock input via SMA connector J16. (X3 and J17 not installed)
The default configuration is that the clock is supplied by the SPWCLK oscillator X3, and
jumper J17 is not installed. Do not install jumper J17 if an oscillator is installed in X3 socket
as this will unintentionally connect the outputs of oscillator X1 and Oscillator X3 together.

2.6 erial Interface
The UT699RH AS C, provides a single Serial port, with TXD/RXD pins, and the GR-UT699
board provides an RS232 driver/receiver chip and routes these signals to a front panel
connector.
The front panel connector type for the UART interface is Female D-Sub 9 pin type with a
standard pin-out for serial links.
2.7 Debug upport Unit (D U) erial Interface
The GR-UT699 unit provides a interface for Debug and control of the processor by means of
a host terminal via the DSU serial link to the UT699 AS C, as represented in Figure 2-8.
The board provides two possibilities for connecting to the processor's DSU interface:
1. USB MiniAB connector with USB to Serial interface chip
2. JTAG DSU interface
The baud rate of the serial link is specified by the host computer, and the DSU interface in
the UT699 AS C auto-detects and adjusts its baud rate to suit.
The DSUENable signal input to the processor is connected to a jumper on the PCB. n

2.9 Power upply and Voltage Regulation
The board operates from a single +5V DC power supply input. On board regulators generate
the following voltages:
•+3.3V for the UT699 /O voltage, memory chip and other peripherals
•+2.5V for UT699 Vcore voltage
All voltages +5V, +3.3V, ±12V are provided via the memory expansion connector interface
making feasible that user defined mezzanine boards can use these voltages.
f the Board is installed in a Compact PC rack, the board can be configured by means of
jumpers such that the +5V, +3.3V, +12V and -12V are provided from the Compact PC
backplane instead of the internal regulators.
2.10 Ethernet Interface
The UT699RH AS C device incorporates a Ethernet controller with support for M interface,
and the GR-UT699 Development Board has an ntel LXT971 10/100Mbit/s Ethernet PHY
transceiver and RJ45 connector are on board.
For more information on the registers and functionality of the Ethernet MAC+PHY device
please refer to the data sheet for the WJLXT971A device.
A 25MHz oscillator dedicated for this device is provided on the board.
The interrupt output of the Ethernet MD O interface is connected to the PIO[4] input to the
UT699 AS C. This can be disabled by removing jumper JP2 if necessary.
