1.2 About the MPS2 and MPS2+ FPGA Prototyping Boards
The MPS2 and MPS2+ FPGA Prototyping Boards are development platforms for Arm Cortex‑M
evaluation and development.
The MPS2 and MPS2+ FPGA Prototyping Boards provide the following:
Altera Cyclone FPGA and board powerup and configuration
The MPS2 FPGA Prototyping Board provides an Altera Cyclone 5CEA7 FPGA, and the
MPS2+ FPGA Prototyping Board provides an Altera Cyclone 5CEA9 FPGA, both speed grade
C8. Both boards support Arm Cortex‑M software evaluation and development. A Motherboard
Configuration Controller (MCC) supports board powerup and configuration. An on‑board
EEPROM stores board and file identification information and a microSD card stores FPGA and
software images and configuration files. You can access the microSD card to perform
configuration file editing and to update FPGA and software images.
Caution
Images that are created for the Altera Cyclone 5CEA7 FPGA are not compatible with the Altera
Cyclone 5CEA9 FPGA. Images that are created for the Altera Cyclone 5CEA9 FPGA are not
compatible with the Altera Cyclone 5CEA7 FPGA.
External user memory
On‑board external SSRAM and PSRAM connect to memory interfaces in the FPGA.
Access ports
The MPS2 and MPS2+ FPGA Prototyping Boards provide access through Ethernet,
general‑purpose UART, and SPI ports. A general‑purpose user expansion port supports user
expansion to extra signal or bus I/O.
Video and audio output
The MPS2 and MPS2+ FPGA Prototyping Boards provide video output through VGA and
CLCD ports. The CLCD port drives an LCD module that is configured for SPI graphics and I

touch screen. Input and output audio ports connect to a stereo audio codec which connects to an
I

S digital audio interface on the FPGA.
User LEDs and user switches
The MPS2 and MPS2+ FPGA Prototyping Boards provide user LEDs, an 8-way dip switch and
push buttons that connect to the FPGA and to the MCC. The meaning of these LEDs and push
buttons depend on the image that you implement in the FPGA.
System LEDs
The MPS2 and MPS2+ FPGA Prototyping Boards provide LEDs which denote Configuration
Complete, MCC Powered, Ethernet Duplex Link Established, Ethernet Link Operating at
100Mbs, Ethernet Link Established, and microSD Card Read or Write Access.
