The ebay listing provided by Axk above includes the following blurb:
"Lichee Tang uses Anlogic Technologies' EG4S20 as the core unit, 20K logic unit (LUT4/LUT5 hybrid architecture), approximately 130KB
S RAM, built-in 32bit bit width 64MBit SDRAM, rich LVDS pin, built-in 12-bit 1MSPS ADC. "
Offhand that does not resemble any lattice product does it? especially the LUT4/LUT5. I am however not that familiar with the full breadth of the lattice line.
