This commercial-grade device is suited to applications that require dense logic, abundant I/O, and embedded memory while operating within standard commercial temperature and voltage ranges.

Key Features

• Logic Capacity — 813,050 logic element cells provide a large programmable fabric for complex digital designs.
• Configurable Logic Blocks (CLBs) — 32,522 CLBs enable structured placement of logic resources across the device.
• Embedded Memory — Approximately 34 Mbits of embedded memory (34,093,056 total RAM bits) for on-chip data buffering, FIFOs, and local storage.
• I/O Density — 1,120 I/O pins support high pin-count interfacing and parallel connectivity to external devices.
• High‑Speed Transceiver and I/O Features — Stratix IV family documentation highlights high-speed differential I/O, transceiver features including DPA and Soft-CDR, and broad protocol support for high aggregate data bandwidth.
• DSP and System Blocks — Device handbook references digital signal processing (DSP) blocks and rich clock/PLL resources for timing, synchronization, and numeric processing tasks.
• Package and Mounting — 1760-FCBGA package (listed as 1760-BBGA, FCBGA / supplier package 1760-FCBGA (42.5x42.5)); surface-mount device for high-density board designs.
• Power and Temperature — Supply voltage range listed as 870 mV to 930 mV; commercial operating temperature range 0°C to 85°C.
• Compliance — RoHS compliant.

Typical Applications

• High-Bandwidth Communications — Use where high aggregate data throughput and robust high-speed transceiver features are required for protocol handling and data aggregation.
• Digital Signal Processing — Leverage on-chip DSP blocks and abundant logic to implement filtering, transforms, and numeric pipelines.
• Memory-Intensive Interfaces — The device’s embedded memory and external memory interface support are suited for buffering, frame storage, and wide-data-path interfacing.
• System Integration and Prototyping — Large logic capacity and high I/O count make this FPGA useful for integrating multiple subsystems and validating complex designs in hardware.

Unique Advantages
