Page 7: Introduction
GR716-BOARD Introduction Overview This document describes the GR716-BOARD Development Board. This equipment is intended to be used as a platform for the demonstration of the Cobham Gaisler GR716 RAD Hard Microcontroller. Furthermore, this board provides developers with a convenient hardware platform for the evaluation and development of software for the GR716 microcontroller. -
Page 8: Handling
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). GR716-BOARD-UM, May 2019, Version 0.1 www.cobham.com/gaisler... -

BOOTSTRAP/ CONFIGURATION CONFIGURATION Figure 4-1: GR716-BOARD Board Block Diagram Note that not all features and interfaces are available at the same time, and the configuration of on-board resistors plus programming of registers is required to access some of the features. -
Page 10: Board Mechanical Configuration
Figure .4-2: GR716-BOARD Board Dimensions The expansion connectors P1 and P2 of the GR716-BOARD are stacking style connectors having a socket on the bottom side and an extended pin on the top side. In a stand-alone configuration the pins on the top side allow easy access for Logic Analyser or Oscilloscope probing for all the functional microcontroller pins. -

Page 13: Gr716 Microcontroller
GR716-BOARD GR716 Microcontroller The Cobham Gaisler GR716 Microcontroller features a fault-tolerant LEON3 SPARC V8 processor, communication interfaces and on-chip ADC, DAC, Power-on-Reset, Oscillator, Brown-out detection, LVDS transceivers, regulators to support for single 3.3V supply, ideally suited for space and other high-rel applications. -
Page 14: Memory
These signals are connected from the GR716 microcontroller to the Expansion connector, P2. 100 Ohm Termination resistors and fail-safe resistors for the LVDS receiver signals are mounted on the board close to the receiver. GR716-BOARD-UM, May 2019, Version 0.1 www.cobham.com/gaisler... -
Page 15: Gpio
No current limiting or overvoltage protection components are included on the GPIO signals of the GR716-BOARD board. The signals are connected directly from the microcontroller to the 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. -
Page 16: Debug Support Unit Interfaces
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 4-9. -
Page 17: Oscillators And Clock Inputs
GR716-BOARD Oscillators and Clock Inputs The oscillator and clock scheme for the GR716-BOARD Board is shown in Figure 4-11. 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 crystal is required on the board which is connected to the Crystal oscillator interface for the GR716. -
Page 18: Power Supply And Voltage Regulation
INA219 Current/Power Monitor circuits with an I2C interface are incorporated on the board. The I2C signals (SDA, SCL) are connected to the Expansion connector P2 to allow the current/voltage to be measured using an I2C master circuit.

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 4-9). 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. -
