The LatticeSC/M (System Chip/MACO) family of FPGAs combines a high-performance FPGA fabric, 3.8Gbps SERDES and PCS, 2Gbps Parallel I/Os, low-power 1V Vcc option, large embedded RAM, and embedded ASIC blocks to provide the highest performing FPGA in the industry.
Designed with the needs of today's high-speed connectivity-based systems in mind, LatticeSC family delivers best in class solutions for high throughput standards like Ethernet, PCI Express, SPI4.2 and high speed Memory Controllers. LatticeSC is equipped with embedded memory, hierarchical clocking and clock management resources for high-end system designs. For low-cost, system-level integration, the LatticeSCM family offers MACO (Masked Array for Cost Optimization): up to 12 embedded structured ASIC blocks per device with a variety of pre-engineered IP blocks.

LatticeSC Evaluation Boards
Lattice has developed three platforms for evaluating the features and performance of the LatticeSC FPGA.
LatticeSC Communications Board: This board is an advanced communications platform that will help you explore how the LatticeSC performs to a variety of communications standards and specifications. Features of this board include a 300-pin MSA transponder interconnection to evaluation Single Data Rate (SDR) performance for SFI-4.1/XSBI applications, a Molex VHDM interconnection to system packet interface level 4-phase 2 (SPI-4.2), a 200-pin SODIMM socket supporting 64-bit 200-pin DDR-2 SDRAM, numerous SMA test points for high-speed SERDES and Clock I/O, and much more.
LatticeSC PCI Express x8 Evaluation Board: This board will help you evaluate the performance of the LatticeSC in additional application spaces. Key features of this board include a x8 PCIexpress edge connector / form-factor, on-board DDR2 Memory, BNC edge connectors for Digital Video Interface, SMA connectors for SERDES I/O, LVDS evaluation, and external clock I/O, and more.
LatticeSC PCI Express x1 Evaluation Board: Key features of this board include a x1 PCIexpress edge connector / form-factor, On-board QDR2 and RLDRAM2 Memory, SATA Host/Target, 1Gbe SFP, SMA connectors for SERDES I/O, LVDS evaluation, and external clock I/O, Tri-speed Ethernet PHY with RJ45 jack, RS-232 port, and more. |
The LatticeSC should finally silence the skeptics: this is a very high performance FPGA that will compete aggressively with Virtex and Stratix devices for sockets. With the simultaneous announcement of the low cost LatticeECP2 devices, Lattice now has the breadth and depth of FPGA products to become the third force in the FPGA market.
