Ultimate ECP5 Board

WIP - Rev 1.0 prototypes currently under test...

Key Features

• Largest ECP5; LFE5UM5G-85F
• PCIe 2.0 x2 card edge connector on two SERDES channels
• Remaining two SERDES channels on M.2 E-key connector
• 1GByte x32 DDR3L (two x16 chips)
• Dedicated HDMI output, using TFP410 serialiser
• 1000BASE-T GbE connector with RGMII PHY
• USB-A 2.0 host connector with ULPI PHY
• FT2232H for debug JTAG and UART/FIFO with type-C connector
• PCIe, external 12V or USB power input
• 12 bicolour (tristate) user LEDs, 4 user buttons, 8 user DIP switches
• 128Mbit QSPI flash for boot and data
• microSD card connector
• Dual PMOD connector with extra "middle" IO pins
• As many remaining IO as possible on high speed FFC connectors with a differential optimised pinout (3x 24 IO). Selectable 1.8V/2.5V/3.3V

Layout

• PCIe card form factor
• At least Ethernet, USB-A, USB type-C power/debug and HDMI out
• 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
