• Embedded Memory  Approximately 2.70 Mbits of on-chip RAM for FIFOs, buffers and local data storage.
• I/O and Packaging  488 user I/Os in a modular I/O bank structure; supplied in a 780-BBGA / 780-FBGA (29×29) surface-mount package.
• Core Voltage Range  Selectable core voltage operation from 0.86 V to 1.15 V to balance performance and power.
• Clocking and PLLs  Support for multiple clock domains with up to 16 global clocks, 88 regional clocks and 116 peripheral clocks, plus up to 12 PLLs for clock synthesis and dynamic phase control.
• High-speed DSP Support  Stratix III family DSP features include dedicated multiplier blocks and multiply-accumulate resources suitable for signal processing workloads (series-level capability documented in the device family handbook).
• Memory Interface Support  Series-level support for external memory interfaces including DDR, DDR2, DDR3, RLDRAM II, QDR II and QDR II+ (documented in the device family material).
• Security and Reliability  Device-family features include optional 256-bit AES volatile and non-volatile configuration key support, CRC for configuration memory error detection and ECC for on-chip memory protection.
• Operating Range and Compliance  Commercial-grade device with an operating temperature range of 0 °C to 85 °C and RoHS-compliant status.

Typical Applications

• High-performance logic and DSP systems  Implement compute-intensive algorithms and signal processing chains using the device's logic capacity and DSP resources.
• Memory controller and interface bridges  Use the device's memory-interface support and abundant I/O to implement DDR/DDR2/DDR3 and other high-speed memory controllers.
• Networking and communications  Leverage multiple clocks, PLLs and modular I/O banks to build protocol engines, packet processors and high-speed communication endpoints.
• Prototyping and ASIC replacement  Programmable logic density and embedded memory make this device suitable for prototyping or as a programmable alternative to custom ASICs for complex systems.

Unique Advantages

• High logic density: 67,500 logic elements give designers room for complex state machines, custom pipelines and DSP logic without immediate migration.
• Significant on-chip RAM: Approximately 2.70 Mbits of embedded memory reduces external memory dependence for many buffering and storage needs.
• Extensive I/O flexibility: 488 user I/Os and modular bank architecture simplify routing of multiple high-speed interfaces and mixed I/O standards.
• Power and voltage flexibility: Selectable core voltage range (0.86–1.15 V) supports trade-offs between performance and power consumption at the system level.
• Security and data integrity: Built-in support for AES configuration keys, CRC and ECC provides mechanisms for protecting and validating configuration and user data.
• Commercial-grade reliability: Surface-mount 780-FBGA packaging and documented operating range (0 °C to 85 °C) align with typical commercial embedded system requirements.
