• I/O Count & Standards  301 user I/O pins and support for LVTTL, LVCMOS, SSTL-2, SSTL-3 I/O standards enable broad system interfacing options.
• High-speed Serial and Parallel I/O  Supports high-speed LVDS (up to 640 Mbps) and RSDS (311 Mbps) interfaces; supports 66- and 33-MHz, 64- and 32-bit PCI signaling for peripheral connectivity.
• Clocking Resources  Up to two PLLs per device with multiple global clock resources to implement clock multiplication and phase shifting for complex timing domains.
• Memory and External Interfaces  Architecture supports external memory interfaces including DDR SDRAM, FCRAM, and SDR SDRAM for systems requiring expanded external storage.
• Package & Mounting  400-ball FineLine BGA (400-FBGA, 21×21) surface-mount package balances pin count and board-area efficiency for compact systems.
• Power & Operating Range  Voltage supply range from 1.425 V to 1.575 V and commercial operating temperature from 0 °C to 85 °C.
• Compliance  RoHS compliant for lead-free manufacturing environments.

Typical Applications

• Data-path Processing  Use the device’s large logic density and embedded RAM to implement packet processing, stream alignment, and custom datapath pipelines.
• Memory Interface and Buffering  Implement DDR SDRAM or SDRAM controllers and local buffering utilizing the device’s on-chip RAM and external-memory support.
• High-speed I/O Bridging  Leverage 301 I/Os and LVDS support to realize high-speed board-level interfaces, SERDES-less data links, and parallel-to-serial bridging.
• Custom Peripheral and Bus Logic  Implement PCI-compatible interfaces, glue logic, and custom peripheral controllers that require flexible I/O standards and abundant logic resources.

Unique Advantages

• High Logic Density:  With up to 20,060 logic elements, the device supports complex RTL implementations without external glue logic.
• Substantial On-chip Memory:  Approximately 0.295 Mbits of embedded RAM reduces reliance on external memory for small buffers and state storage.
• Flexible I/O and Signaling:  301 I/O pins and support for multiple I/O standards, LVDS, and PCI signaling simplify integration with a wide range of peripherals and boards.
• Integrated Clocking:  Dual PLLs and multiple global clock resources enable robust multi-domain clock architectures and timing adjustments on-chip.
• Compact Surface-mount Package:  The 400-FBGA (21×21) package provides high pin density in a compact footprint for space-constrained PCBs.
• Design Migration and Tool Support:  Cyclone family features facilitate device migration across densities and are supported by vendor design flows and IP cores documented in the device handbook.
