4 Board Design
4.1 Board Block Diagram
The GR716-CPCI-DEV Board provides the electrical functions and interfaces as
represented in the block diagram Figure 4-1.
Note that not all features and interfaces are simultaneously available since the pins of
the GR716 microcontroller have multiple functions. The available interfaces depends on
the configuration and programming of the registers of the GR716 Microcontroller, and
on the connections made by the Interface Configuration Module.

4.3 GR716-BOARD and Expansion Boards
The GR716-CPCI-DEV provides two sites with two 2x32 pin headers to allow the board
to function as a carrier board for the GR716-BOARD (Figure 4-4).
The first set of headers (P1, P2) is intended for mounting the GR716-BOARD as shown
in Figure 4-3
The second set of headers connect with a one-to-one correspondence with the first set
and is intended for the mounting a GR716-TEST-MEMORY board (Figure 4-5), to
provide the GR716-BOARD with extended FLASH and SRAM external memory.
Alternatively, the second set of headers provides a convenient way for User Defined
interface boards to be developed and connected to the GR716-CPCI-DEV, if other
functions or features are to be demonstrated.

4.4 Interface Configuration Board
Since the GR716 microcontroller has pins with multiple functions, it is necessary to
have a way to route pins from the GR716-BOARD to the interface circuits in a way that
prevents signal and interface conflicts.
This is achieved on the GR716-CPCI-DEV board by means of Interface configuration
Boards as shown in Figure 4-6.
These boards can be configured by means of installing or removing solder bridges in
order to route connections from the GPIO pins of the GR716-BOARD to the interface
circuits on the GR716-CPCI-BOARD.
The organisation of the solder bridges corresponds with the organisation of the IO
Configuration Options shown in Table 7 of [RD1].
The Interface Configuration Board mounts on to the GR716-CPCI-DEV board
undernearth the Expansion Board, as shown in Figure 4-7.

4.5 GPIO
All 64 GPIO pins can be connected from the GR716-BOARD via the Expansion
Connector to the GR716-CPCI-DEV.
These 64 general Purpose Input Output signals (3.3V LVCMOS voltage levels) are
connected to a set of 0.1” pitch pin headers and from there via ribbon cable the front
panel of the GR716-CPCI-DEV board, thus allowing easy access to these signals, either
individually, or with a ribbon cable connection. A series protection resistor of 470 Ohm
is included on each signal at the front panel connector.
To indicate the state of the GPIO pins, LED indicators are provided on the front panel.
Note that the state of some of the GPIO pins are sampled at power-up or reset of the
processor in order to determine initial conditions of a number of internal features, as
listed in Table 22 of [RD1] and as described in section 4.15.
4.6 SPW
The GR-CPCI-DEV board provides LVDS transceivers to connect the dedicated
SpaceWire interface signals of the GR716 microcontroller to a 10 pin header J7. This
header is connected with wire tails to a MDM9S connector on the front panel to provide
a standard SpaceWire interface.

MMCX coaxial connectors J17 to J20.
The eight ADC voltage inputs to the GR716-BOARD are connected to a miniature
MMCX coaxial connectors J21 to J27 and J29.
4.15 Bootstrap Signals
A number of features of the GR716 microcontroller are required to be set at power-on of
the processor, by means of bootstrap pins. A number of GPIO and function pins are predefined for this purpose, according the definition Table 22 of [RD1].
To define the desired setting, an 8 pole, DIP switch (S1), is provided on the front panel
of the GR716-CPCI-DEV board to connect these signals to DGND or via pull-up to
3V3.
Note: A DIP switch for setting these Bootstrap signals also exists on the GR716-
BOARD ([RD5]). The DIP switches on the GR716-BOARD should be set to ‘float’ to
ensure that there is no conflict with the DIP switch settings on the front panel of the
GR716-CPCI-DEV board.

Program download and debugging to the processor is performed using the GRMON
Debug Monitor tool from Cobham Gaisler ([RD4]). The GR716 microcontroller
provides a UART based DSU interface for Debug and control of the processor by means
of a host terminal, as represented in Figure 4-10.
Four control signals from the Debug Support Unit interface to the processor are
implemented:
DSUTX Debug UART Transmit
DSURX Debug UART Receive
DSUEN This signal is pulled high on the board to enable Debugging
DSUBRE This signal is pulled low on the board
These signals are connected via the Expansion Connector interface from the GR716-
BOARD to an FTDI USB interface. This allows a USB connection to be made to a host
computer.

4.17 Oscillators and Clock Inputs
The GR716-CPCI-DEV Board provides four DIL sockets to allow an external oscillator
clocks to be connected to the following clock inputs of the GR716 microcontroller:
EXT_SYSCLK
EXT_SPWCLK
EXT_1553_CLK
EXT_PWMCLK
For more details of the internal Crystal Oscillator, PLL structure and clock gating
features of the GR716, please refer to sections 9 and 10 of [RD1].
4.18 Power Supply and Voltage Regulation
The power configuration is represented in Figure 4-11.
The main voltage supply input can be provided from one of the following sources:
1. VIN input supply via connector J33.
2. VIN input supply via connector J34.
3. VIN provided via CPCI Backplane connector
VIN is regulated on the GR716-CPCI-DEV board to with a local Point-of-Load DC/DC
converter to generate a +3V3 voltage supply for the local circuits on the GR716-CPCI-
DEV board.
VIN is also connected to the GR716-BOARD via the expansion connector P2, where it
is further regulated for the GR716 microcontroller, as described in [RD5].
The VIN voltage should have a nominal value of 12V. However, due to the wide input
voltage range capability of the POL DC/DC converters used, the input voltage may
range from 5V to 17V.
Note though that, due to the 15V transzorb protection diode on the GR716-CPCI-DEV
board, the input voltage on this board should not exceed 14.5V.

GR716-CPCI-DEV
4.19 Reset Circuit and Button
The GR716 microcontroller includes an internal RESET circuit with Brown-out detector
to reset the processor and its peripherals (see section 8 of [RD1]).
The resulting low reset signal is present on the microcontroller pin RESET_OUT_N.
This signal is connected to the expansion connector, P2.
A manual reset of the microcontroller can be generated using the RESET_IN_N signal.
This signal is present on the expansion connector P2, and can be driven from an
external circuity if required. A miniature push button switch is provided on the front
panel of the GR716-CPCI-DEV board to pull this signal low, when the button is pressed.

5 Setting Up and Using the Board
The board is provided with a default configuration set by bootstrap settings.
For additional information, refer to [RD2] and for information about the Bootstrap
signals, refer to section 4.15.
To operate the board stand alone on the bench top, install the power configuration
jumpers appropriately, and +12V supply to the board connector J32.
ATTENTION! To prevent damage to board, please ensure that the
correct power supply voltage and polarity is used with the board.
Do not exceed +14.5V at the power supply input, as this may
damage the board.
The POWER_3V3 power good LED on the front panel should be
illuminated indicating that the power supply is present and the
board is generating the supply voltages that it requires.
Upon power on, the Processor will start executing instructions beginning at the memory
location 0x02000000, which is the start of the external SPI Flash. If the SPI Flash is
'empty' or no valid program is installed, the first executed instruction will be invalid,
and the processor will halt with an ERROR condition.
To perform program download and software debugging on the hardware it is necessary
to use the Cobham Gaisler GRMON3 debugging software, installed on a host PC (as
represented in Figure 4-10). Please refer to the GRMON3 documentation for the
installation of the software on the host PC (Linux or Windows), and for the installation
of the associated hardware dongle.
To perform software download and debugging on the processor, a link from the Host
computer to the DSU interface of the board is necessary. As described in section 4.16
this is achieved via the FTDI USB interface.
Program download and debugging can be performed in the usual manner with
GRMON3. More information on the usage, commands and debugging features of
GRMON3, is given in the GRMON3 Users Manuals and associated documentation,
[RD4].
