General Description
Cyclone III 3C120 Development Board Reference Manual © March 2009 Altera Corporation
The Cyclone III development board has the following main features:
■ High logic density to implement more functions and features
■ Embedded memory for high-bandwidth applications
■ Expandable through two Altera High-Speed Mezzanine Connectors (HSMCs)
■ 256-MB of dual channel DDR2 SDRAM with a 72-bit data width
■ Supports high-speed external memory interfaces including dual-channel DDR
SDRAM and low-power SRAM
