Ultimate ECP5 Board

Key Features

• Largest ECP5; LFE5UM5G-85F
• PCIe 2.0 x2 card edge connector on two SERDES channels
• Remaining two SERDES channels muxed using high-speed mux:
  • 2-lane mini DisplayPort transmit and receive connectors
  • or USB type-C connector (with proper CC logic and ULPI PHY for USB 2.0)
  • Must have flexible SERDES clocking for a range of protocols with passive adapters (SFP, SATA, etc)
• 1GByte or 2GByte x32 DDR3, either chips or half SODIMM
• Dedicated HDMI output, probably using TFP410 serialiser for a simpler video output than DP
• Dual GbE connectors with RGMII PHYs
• USB-A 2.0 host connector with ULPI PHY
• 2nd USB-A connector directly connected to FPGA
• FT2232H for debug JTAG and UART/FIFO on second USB type-C connector also used for normal board power (up to 5V 3A)
• Optional PCIe 12V power input connector
• At least 8 user LEDs, 4 user buttons, 4 or 8 user DIP switches
• 128Mbit QSPI flash for boot and data
• microSD card connector
• Audio I/O with I2S codec
• Dual PMOD connector
• As many remaining IO as possible on high speed FFC connectors with a differential optimised pinout (at least 100-150 IO using this)

Layout

• PCIe card form factor
• At least Ethernet, 2x miniDP and 2x USB-C on exposed side when in a case used as a PCIe card
• Other connectors probably would have to be on other sides. FFC connectors probably on top so they can loop over to another card to form a 2-slot card (e.g. with ADCs/DACs for SDR/DAQ)

Possible accessories using high-speed FFC connectors

• MIPI DSI smartphone-style LCDs
• MIPI CSI-2 cameras
• High speed ADC/DAC
• HDMI in/out, direct or using serialiser chip
• LVDS video in/out for LCDs or block cameras
• Breakout board to dual or triple PMOD
