EP4SGX290FH29C2XN

The EP4SGX290FH29C2XN is a Stratix IV GX Field Programmable Gate Array (FPGA) IC from Intel, delivered in a 780-BBGA FCBGA package for surface-mount assembly. It combines a high logic element count with substantial on-chip memory and advanced I/O capabilities to address high-bandwidth, protocol-rich designs.

Targeted at commercial applications that require dense programmable logic, embedded memory and flexible I/O, this device is supported by the Stratix IV device handbook and associated architecture references for system integration, clocking and transceiver features.

Key Features

• Core Logic — 291,200 logic elements (cells) provide a high-density fabric for complex custom logic implementations.
• Embedded Memory — Approximately 17.66 Mbits of on-chip RAM (17,661,952 total RAM bits) for buffering, packet storage and local data handling.
• I/O Capacity — Up to 289 general-purpose I/O pins to support broad interfacing requirements and multiple external peripherals.
• High‑Speed Transceiver and I/O Features — Stratix IV GX series device handbook documents high-speed differential I/O, transceiver capabilities and features such as DPA and soft-CDR for protocol support and signal integrity.
• Clocking and PLLs — Device family documentation describes dedicated clock networks and PLL resources to support multi-clock systems and high-performance timing architectures.
• Package and Mounting — 780-BBGA (FCBGA) package, supplier device package listed as 780-HBGA (33×33), designed for surface-mount assembly.
• Power — Core voltage supply range specified at 870 mV to 930 mV to match platform power rails and regulator designs.
• Operating Conditions and Grade — Commercial grade with an operating temperature range of 0 °C to 85 °C and RoHS compliance.

Typical Applications

• High‑bandwidth Communications — Implement protocol engines, SERDES interfaces and packet-processing logic that leverage the device’s transceiver features and large logic fabric.
• Signal Processing and DSP — Use embedded memory and the Stratix IV DSP-oriented architecture elements for real-time filtering, encoding/decoding and media processing.
• External Memory Interfaces — Implement controllers and custom memory interfaces using available I/O resources and device clocking networks.
• Custom Accelerator Logic — Deploy compute- or offload-oriented accelerators that require high logic density and local RAM for intermediate data storage.

Unique Advantages

• High Logic Density: 291,200 logic elements enable integration of complex systems-on-FPGA without immediate need for multiple devices.
• Substantial On‑Chip Memory: Approximately 17.66 Mbits of embedded RAM reduces external memory dependence for many buffering and scratchpad needs.
• Rich I/O and Transceiver Support: 289 I/O pins paired with Stratix IV GX transceiver features support diverse protocol and interface requirements.
• Platform‑Level Clocking: Dedicated clock networks and PLL resources documented for the Stratix IV family help implement robust multi-clock designs.
• Commercial‑Grade Reliability: Specified operating range (0 °C to 85 °C) and RoHS compliance suit mainstream commercial applications and manufacturing processes.
• Compact, Surface‑Mount Package: 780-BBGA (33×33 supplier package) provides a high I/O footprint in a single, mountable package for compact system boards.
