The DE2i-150 board has many features that allow users to implement a wide range of designed
circuits, from simple circuits to various multimedia projects.
The following hardware (FPGA System) is provided on the DE2i-150 board:
Altera Cyclone® IV 4CX150 FPGA device
Altera Serial Configuration device –EPCS64
USB Blaster (on board) for programming; both JTAG and Active Serial (AS) programming
modes are supported
Two 2MB SSRAM
Two 64MB SDRAM
64MB Flash memory
SD Card socket
4 Push-buttons
18 Slide switches
18 Red user LEDs
9 Green user LEDs
50MHz oscillator for clock sources
VGA DAC (8-bit high-speed triple DACs) with VGA-out connector
TV Decoder (NTSC/PAL/SECAM) and TV-in connector
Gigabit Ethernet PHY with RJ45 connectors
RS-232 transceiver and 9-pin connector

7
IR Receiver
2 SMA connectors for external clock input/output
One 40-pin Expansion Header with diode protection
One High Speed Mezzanine Card (HSMC) connector
16x2 LCD module
In addition to these hardware features, the DE2i-150 board has software support for standard I/O
interfaces and a control panel facility for accessing various components. Also, the software is
provided for supporting a number of demonstrations that illustrate the advanced capabilities of the
DE2i-150 board.
In order to use the DE2i-150 board, the user has to be familiar with the Quartus II software. The
necessary knowledge can be acquired by reading the tutorials “My_First_Fpga”. These tutorials are
provided in the directory DE2i_150_tutorials on the DE2i-150 System CD that accompanies the DE2i-150 kit and
can also be found on Terasic‟s DE2i-150 web pages.

Figure 1-3 gives the block diagram of the DE2i-150 board. To provide maximum flexibility for the
user, all connections are made through the Cyclone IV GX FPGA device. Thus, the user can
configure the FPGA to implement any system design.
