Cyclone® III FPGAs offer an unprecedented combination of low power, high functionality, and low cost. The architecture consists of up to 120K vertically arranged logic elements (LEs), 4 Mbits of embedded memory arranged as 9-Kbit (M9K) blocks, and 200 18x18 embedded multipliers. Cyclone III LS FPGAs have a memory-rich and multiplier-rich floorplan consisting of up to 200K logic elements, 8.2 Mbits of embedded memory, and 396 embedded multipliers.
Both architectures include highly efficient interconnect and low-skew clock networks, providing connectivity between logic structures for clock and data signals. The logic and routing core fabric is surrounded by I/O elements (IOEs) and phase-locked loops (PLLs), as shown in Figure 1.
