3.2 Handling
ATTENTION: OBSERVE PRECAUTIONS FOR
HANDLING ELECTROSTATIC SENSITIVE DEVICES
This unit contains sensitive electronic components which can be damaged by
Electrostatic Discharges (ESD). When handling or installing the unit observe
appropriate precautions and ESD safe practices.
When not in use, store the unit in an electrostatic protective container or bag.
When configuring the jumpers on the board, or connecting/disconnecting cables, ensure
that the unit is in an un-powered state.
When operating the board in a 'stand-alone' configuration, the power supply should be
current limited to prevent damage to the board or power supply in the event of an overcurrent situation.
This board is intended for commercial use and evaluation in a standard laboratory
environment, nominally, 20°C. All devices are standard commercial types, intended for
use over the standard commercial operating temperature range (0 to 70ºC).

4.8 Analog Signals
The GR716-MINI board provides four micro-miniature (MMCX) coaxial connectors to
allow access to up to 4 ADC inputs or 4 DAC outputs of the GR716 microcontroller.
As shown in Figure 4-11, depending on which resistors are installed, each MMCX
connector can be either an ADC input or a DAC output.
Access to the ADC/DAC configurable from software via configuration registers, and for
further information please refer to [RD1]
The nominal input range for the ADC inputs is 0 – 2.0V
The DAC outputs are current outputs with a full-scale range of 0 – 4mA.
No current limiting or overvoltage protection components are
included on the GPIO/Analog signals of the GR716-MINI board.
The signals are connected directly from the microcontroller to the
coaxial/expansion connector. Care must therefore be taken to
ensure that any external circuitry connected does not exceed the
allowable voltage limits for the input/output pins.

4.10 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.
Either the pull-up or the pull-down resistor should be installed to defined the desired
setting, according the definition Table 22 of [RD1].

4.11 Debug Support Unit Interfaces
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 4-12.
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
The DSUTX and DSURX signals are connected to the FTDI UART to USB converter
chip, allowing easy connection to a host PC using a USB cable.

4.12 Oscillators and Clock Inputs
The oscillator and clock scheme for the GR716-MINI Board is shown in Figure 4-13.
Two oscillator inputs are required: CLK for the main system clock, and SPW_CLK for
the SpaceWire clock of the microcontroller
To allow the GR716 Microcontroller to operate in a stand alone manner a soldered
20MHz crystal is installed on the board which connected to the Crystal oscillator
interface for the GR716.
This generates a 20MHz output clock, XO_OUT, which is connected to the CLK and
SPW_CLK inputs with zero-ohm resistors.
In an alternative scenario, it may be preferred to have a separate CLK or SYS_CLK to
allow different frequencies to be used. In this case the 0R resistors can be removed, and
instead the 'not-fitted' resistors be placed with zero-ohms to allow an external 3.3V
LVCMOS oscillator input to provided via the expansion connector.
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].
A separate 12 MHz crystal is required for the FTDI interface IC.

4.13 Power Supply and Voltage Regulation
The power configuration is shown in Figure 4-14.
On this board, the microcontroller is configured to operate from a single +3.3V power
rail. The VDD_CORE (1.8V) is generated by a LDO regulator inside the GR716 itself.
To allow the board to be powered from the +5V supply provided on a standard USB
connector/cable, a LMZ21701 micro Point-of-Load regulator is included on the board
which generates the 3.3V for the rest of the GR716-MINI board.
In an alternative scenario, when the GR716-MINI board is installed on an Expansion
board or Motherboard, it is intended that the Motherboard should generate a regulated
3.3V supply and provide this via the Expansion connector.
In this configuration, the jumper JP1 should be removed to disconnect the USB cable
voltage, and the regulator is disabled by pulling its Enable signal low with the MB pin
on the expansion connector
Note: it is not the intention that the on-board POL regulator is used to provide
significant current toward other loads on the Expansion Board/Motherboard.

4.14 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, P1.
To provide a manual reset of the microcontroller, a miniature push button switch, S1, is
provided on the PCB which connects to the RESET_IN_N signal.
This signal is also present on the expansion connector P1, and can be driven from an
external circuity if required.
4.15 Watchdog
The GR716 microcontroller includes an internal Watchdog timer function which can be
used for the purpose of generating a system reset in the event of a software malfunction
or crash. Please refer to [RD1].

5 Setting Up and Using the Board
The board is provided with a default configuration set by bootstrap resistors. These
define the configuration at power on of the board
Other configurations may be defined by the user, by installing/removing the bootstrap
resistors.
For additional information, refer to [RD2] and for information about the Bootstrap
signals, refer to section 4.10.
There is one miniature jumper on the board as shown in Table 5.
Jumper Comment
JP1 Install to allow 5V supply from USB cable to provide power to the board.
Remove if board is installed on a motherboard and +3V3 power is provided
from the carrier board via connector P1
Table 5: Default Setting of Jumpers
To operate the board stand alone on the bench top, connect the board with a Micro USB
cable to a USB port on a host computer/laptop. This provides +5V supply to the board.
ATTENTION! To prevent damage to board, please ensure that the
correct power supply voltage and polarity is used with the board.
Do not exceed +17V at the power supply input, as this may damage
the board.
The POWER LED should be illuminated indicating that the power
supply is present and the board is generating the +3.3V it requires.
Upon power on, the Processor will start copy a ASW container from 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 4-12). 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 4.11
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].
