Key Features

• Logic Capacity — 291,200 logic elements to support complex digital designs and large-scale integration needs.
• Embedded Memory — Approximately 17.66 Mbits of on-chip RAM for buffering, FIFOs, and memory-intensive logic functions.
• I/O Density — 564 device I/Os to enable broad peripheral and interface connectivity in high-pin-count systems.
• Series Architecture Features — Stratix IV GX series features referenced in the device handbook include high-speed transceiver support, DSP blocks, PLLs, clock networks, and external memory interface capability for demanding signal-processing and communications tasks.
• Power Supply — Core voltage range specified at 870 mV to 930 mV to match system power-rail requirements.
• Thermal and Environmental — Industrial-grade operation with an operating temperature range of −40 °C to 100 °C and RoHS compliance.
• Package and Mounting — Surface-mount 1152-ball BGA package (supplier device package: 1152-FBGA, 35×35), suitable for high-density PCB layouts.

Typical Applications

• High-bandwidth communications — Implements protocol-heavy and high-aggregate-bandwidth functions using the Stratix IV GX series transceiver and clocking features.
• Signal processing and DSP — Large logic capacity and embedded memory support complex digital signal processing pipelines and DSP block utilization.
• System integration and prototyping — High I/O count and flexible interfacing options enable aggregation of multiple peripherals and external memory interfaces for system-level designs.

Unique Advantages

• High integration density: 291,200 logic elements and substantial on-chip RAM reduce reliance on external logic and memory, simplifying board-level designs.
