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 Frontgrade 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, Brown-out
detection, LVDS transceivers, regulators to support for single 3.3V supply, ideally suited for
space and other high-rel applications.

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 over-
current 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.
Figure 4-1: GR716-CPCI-DEV Board Block Diagram
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.

4.2 Board Mechanical Configuration
The board (233.35 x 160mm) and can be used 'stand-alone' on the bench-top simply an
external +12V power supply connected to connector J32.
A 6U format, 2 slot sized CPCI front panel is fitted to allow the board to be installed in a
CPCI rack.
