• High I/O count — 564 I/Os for extensive external interfacing and board-level connectivity.
• Stratix IV GX architecture — Family features include high-speed transceiver functionality, DSP blocks, PLLs, and clock networks as described in the Stratix IV device documentation.
• Power supply range — Core voltage specified between 870 mV and 930 mV for system power planning.
• Package and mounting — 1152-FBGA (35×35) package in a surface-mount form factor for compact, high-density board designs.
• Commercial temperature grade — Rated for 0 °C to 85 °C operating temperature and RoHS compliant.

Typical Applications

• High-bandwidth communications — Use the Stratix IV GX device for designs that leverage the family’s high-speed transceiver features and large I/O count to implement protocol interfaces and packet processing.
• Signal processing and DSP — The available DSP resources and significant on-chip RAM make the device suitable for filter banks, FFTs, and other DSP-intensive functions.
• External memory controllers — On-chip logic and memory combined with the architecture’s external memory interface support are applicable where FPGA-based memory controllers or buffering are required.
• Complex system integration — High logic density and I/O capability enable integration of multiple functions (control, data path, and protocol handling) into a single device.

Unique Advantages

• High integration density: 228,000 logic elements and substantial embedded memory reduce the need for discrete components and simplify board-level partitioning.
• Extensive external connectivity: 564 I/Os enable flexible interfacing to peripherals, memory devices, and high-pin-count connectors without external multiplexing.
• Architecture-level features: Stratix IV GX family capabilities such as high-speed transceivers, DSP blocks, and PLL/clock networks provide building blocks for communication and signal-processing applications.
• Compact package: 1152-FBGA (35×35) surface-mount package supports dense PCB layouts while maintaining a high pin count for system interconnects.
• Design predictability: Commercial operating range (0 °C to 85 °C) and specified core voltage window (870 mV–930 mV) assist in power and thermal planning for production designs.
• Environmental compliance: RoHS compliance supports regulatory and supply-chain requirements for lead-free assembly.
