LatticeECP3 FPGAs offer a broad range of single-ended and differential system I/Os with data speeds up to 1Gbps. The I/Os are arranged in six general purpose I/O banks, as illustrated in the diagram. A variety of external memory interfaces are supported, such as QDR I & II, RLDRAM I & II, and DDR/DDR2/DDR3 at speeds up to 800Mbps. In addition, high speed source synchronous I/Os can be used to implement popular 7:1 LVDS, SPI 4.2, and parallel ADC/DAC interfaces.
