Overview

The Nios Development Board, Stratix II Edition, provides a hardware

platform for developing embedded systems based on Altera

Stratix II

devices. The Nios Development Board, Stratix II Edition provides the

following features:

■ A Stratix II FPGA with more than 13,500 adaptive logic modules

(ALM) and 1.3 million bits of on-chip memory

■ 16 MBytes of flash memory

■ 2 MBytes of synchronous SRAM

■ 32 MBytes of double data rate (DDR) SDRAM

■ On-board logic for configuring the FPGA from flash memory

■ On-board Ethernet MAC/PHY device and RJ45 connector

■ Two 5V-tolerant expansion/prototype headers each with access to 41

FPGA user I/O pins

■ CompactFlash connector for Type I CompactFlash cards

■ 32-bit PMC Connector capable of 33 MHz and 66 MHz operation

■ Mictor connector for hardware and software debug

■ RS-232 DB9 serial port

■ Four push-button switches connected to FPGA user I/O pins

■ Eight LEDs connected to FPGA user I/O pins

■ Dual 7-segment LED display

■ JTAG connectors to Altera devices via Altera download cables

■ 50 MHz oscillator and zero-skew clock distribution circuitry

■ Power-on reset circuitry

General

Description

The Nios development board comes pre-programmed with a Nios II

processor reference design. Hardware designers can use the reference

design as an example of how to build systems using the Nios II processor

and to gain familiarity with the features included. Software designers can

use the pre-programmed Nios II processor design on the board to begin

prototyping software immediately.

This document describes the hardware features of the Nios development

board, including detailed pin-out information, to enable designers to

create custom FPGA designs that interface with all components on the

board. A complete set of schematics, a physical layout database, and

GERBER files for the development board are installed with the Nios II

development tools in the <Nios II EDS install path>/documents directory.
