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