Ultimate ECP5 Board
Key Features
- Largest ECP5; LFE5UM5G-85F
- PCIe 2.0 x2 card edge connector on two SERDES channels
- Remaining two SERDES channels on SATA connectors
- 1GByte x32 DDR3 chips
- Dedicated HDMI output, probably using TFP410 serialiser
- 1000BASE-T GbE connector with RGMII PHY
- USB-A 2.0 host connector with ULPI PHY
- 2nd USB-A connector directly connected to FPGA
- FT2232H for debug JTAG and UART/FIFO with micro-B connector
- PCIe or external 12V power input
- 12 user LEDs, 4 user buttons, 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 (4x 24 IO + ...). Selectable 1.8V/2.5V/3.3V
Layout
- PCIe card form factor
- At least Ethernet, USB-A, micro-USB 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
