— 1451k logic cells.
— Four UARTs (connected to a USB to serial hub for connection to the host computer).
— Support for encrypted FPGA images and Partial Reconfiguration.
• User memory system:
— Up to 8MB internal BRAM.
— microSD card interface.
— 8MB external QSPI flash.
— 4GB, 64‑bit external DDR4 SODIMM.
— 16GB, 8‑bit external eMMC.
• Motherboard Configuration Controller (MCC) that controls the MPS3 board, and supports board
configuration at powerup or reset:
— FPGA configuration.
— Board configuration.
— Supervises user update of the board configuration files in the configuration microSD card.
— Two hardware reset buttons, both labeled PBRST, and two On/Off soft reset buttons, both labeled
PBON.
• Ethernet 10/100 port and Ethernet controller that connects to the Static Memory Controller (SMC)
interface in the FPGA.
• HDMI port and HDMI controller:
— Inputs 24‑bit RGB data from the HDLCD controller in the FPGA.
— Configured over I
2
C directly from FPGA.
— Supports an I
2
S audio connection to the FPGA.
— Drives the HDMI connector.
• Audio codec:
— Provides stereo Line In, stereo Line Out, and stereo Microphone Input In to the stacked stereo
jack audio interface.
— Configured over I
2
C from the I
2
C controller in the FPGA.
— I
2
S audio connection to the I
2
S in the FPGA.
• Shield expansion:
— Two Arduino expansion interfaces for Shields for custom peripherals or off‑the‑shelf sensor
interfaces such as WiFi, Bluetooth, Proximity detectors, or Gyro sensors.
— Each interface connects: 16 × digital 3V3 I/O or 16 × digital 5V I/O, voltage references, and six
analog inputs from each Shield.
• Peripheral Module (Pmod) interface expansion:
— Four Pmod expansion connectors that use the same I/O on an interface that is shared with the
Shield connectors, Type 2A/3/4 support.
— Requires Pmod adapters that provide 8 × analog 3V3 I/O, or 8 × analog 5V I/O.
• FMC‑HPC expansion:
— Connector to enable fitting of an FPGA Mezzanine Card (FMC) High Pin Count (HPC)
expansion card to the MPS3 board.
— A 14‑pin FMC configuration connector and configuration EEPROM to enable configuration of
Arm FMC boards.
• User switches, LEDs, and push buttons that connect directly to GPIO in the FPGA:
— One 8‑way user DIP switch.
— Ten user LEDs.
— Two user push buttons.
• System LEDs:
— Green 12V OK LED.
— Orange 3V3 OK LED.
— Green PWR ON LED.
— Green FPGA configuration LED.
— Green MCC active LED.
— Orange Debug USB active LED.
