GR716-CPCI-DEV
3 Introduction
3.1 Overview
This document describes the GR716-CPCI-DEV Development Board.
Together with the GR716-DEV 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, and allows
the GR716-DEV board to be installed in a CPCI rack for further integration with other
development equipment.
The GR716 Microcontroller features a fault-tolerant LEON3 SPARC V8 processor,
communication interfaces and on-chip ADC, DAC, Power-on-Reset, Oscillator, Brownout detection, LVDS transceivers, regulators to support for single 3.3V supply, ideally
suited for space and other high-rel applications.

The board contains the following main items as detailed in section 4 of this document:
• CPCI 6U format (233.35 x 160mm)
• two sites for plug on modules with two 2x32 pin stackable 0.1” headers
• plug on board for configuration of interface routing to peripherals
• connector for single VIN power input (+5V to +12V)
• front panel with
◦ 0.1” header connectors for 64 GPIO signals (plus ground)
◦ LED’s as status indicators for GPIO signals
◦ two Spacewire connecotrs (MDM9S)
◦ connector for SPI4Space interface (MDM9S)
◦ DIP switch for bootstrap settings
◦ mini USB connector for FTDI-USB interface
◦ LED indicators for Power and ResetOut status
◦ RESET_IN and DSUBREAK push button switches
• on-board headers for ribbon cable connection to
◦ Packetwire interface
◦ CAN interface
◦ DSU plus UART interfaces
◦ MIL1553 interface
◦ SPI peripherals
• miniature coax connectors for 8 x ADC and 4 x DAC analog signals
• jumpers for power supply configuration
• on-board regulators converting from VIN to 3.3V & 1.8V
• sockets for optional on-board oscillator s for
◦ SYSCLK
◦ SPWCLK
◦ MIL1553CLK
◦ PWMCLK

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 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.
