1 INTRODUCTION
1.1 Scope of the Document
This document is a Quick Start Guide for the GR-CPCI-GR716-DEV Development Board.
The purpose of this document is to get users quickly started using the board.
For a complete description of the board please refer to the GR-CPCI-GR716-DEV Development
Board User's Manual.
The GR716 system-on-chip is described in the GR716 Data sheet and User's Manual.
This quick start guide does not contain as many technical details and is instead how-to oriented.
However, to make the most of the guide the user should have glanced through the aforementioned
documents and should ideally also be familiar with the GRMON debug monitor.
This document establishes the Quick Start Guide for the GR-CPCI-GR716-DEV development
board. This document provides example and guides for connecting external interface circuits to the
GR716-BOARD using the GR-CPCI-GR716-DEV Development board for more see [RD2] or
contact support@gasiler.com.

2 OVERVIEW
The GR-CPCI-GR716-DEV Development board provides a comprehensive and rapid prototyping
platform for the GR716 fault tolerant micro controller. The PC/104 style stackable headers (2 x 64
pin) allow for easy expansion, accessibility and integration. Along with the possibility to fit the
microcontroller board GR716-BOARD, the subject board supports following options:
Baseline design for interface application board:
• GR716-BOARD engineering board in dedicated slot
◦ Multiple slots for possibility to attach multiple GR716 engineering boards
• Expansion slot for memory or user defined functions (e.g. SRAM, ADC/DAC)
• Socketed oscillators for system, SpaceWire, Mil-Std-1553B and PWM clocks
• Configuration of front panel functions
• Front panel interfaces
◦ MDM9S for fixed SpW (LVDS) interface
◦ MDM9S for configurable SpW/SPI4S (LVDS) interface
◦ GPIO (64 pins on standard 0.1" connectors)
◦ LED indicators (64) for GPIO pins
◦ DIP switch for bootstrap options
◦ Reset and DSU Break push-button switches
◦ LEDs for power and reset status
◦ FTDI USB interface
▪ GRMON3 debug I/F via Debug UART
▪ 2x UART interfaces, 1x I2C interface
• Power from external supply (range +5V to +12V) or via cPCI backplane connector (+5V)
• Expansion through accessory boards
◦ 6x UARTs using GR-CPCI-6U-UART
◦ CAN, Mil-Std-1553B, SPI using GR-CPCI-GR740
◦ PacketWire using GR-TMTC-PW
◦ Analog frontpanel for 4 ADC connections + 4 DAC connections.
The board has the dimension of 233mm x 160mm, 6U cPCI format, 2 slot wide front panel
