EP4S40G2F40I2NAB

The EP4S40G2F40I2NAB is an Intel Stratix IV GT field-programmable gate array supplied in a 1517-BBGA (1517-FBGA, 40×40) surface-mount package. It combines a high count of logic elements with substantial on-chip RAM and a large I/O complement to address high-bandwidth digital processing and serial communication applications.

Designed for industrial-grade deployments, this device provides 228,000 logic elements, approximately 17.5 Mbits of embedded memory, and support for high-speed transceivers in the Stratix IV GT family—making it suitable for demanding communications, networking, and DSP-centric systems while operating across a broad temperature and voltage range.

Key Features

• Core Logic  228,000 logic elements for implementing complex FPGA fabrics and custom logic functions.
• Embedded Memory  Approximately 17.5 Mbits of on-chip RAM to support large buffering, packet storage, and FPGA-based memory structures.
• Transceivers & Serial Interfaces  Part of the Stratix IV GT family that supports full-duplex CDR-based transceivers with data rates up to 11.3 Gbps, and dedicated circuitry for common serial protocols.
• DSP Capability  Family-level support for high-speed DSP blocks and full-precision multipliers for signal processing (as documented for the Stratix IV family).
• I/O and Packaging  654 user I/O pins in a 1517-BBGA (1517-FBGA, 40×40) FCBGA package, delivered as a surface-mount device for dense board integration.
• Power and Operating Range  Core voltage supply from 920 mV to 980 mV and industrial operating temperature range from −40 °C to 100 °C.
• Standards & Protocol Support  Family-level support for physical-layer functionality for protocols such as PCI Express, Gigabit Ethernet, Serial RapidIO, SONET/SDH, XAUI/HiGig, SD/HD/3G-SDI, Fibre Channel and others.
• Regulatory  RoHS compliant.

Typical Applications

• High-speed Networking  Implements packet processing, switching and interconnect logic for networking equipment using the device’s high I/O count and GT transceivers.
• Telecom and Broadcast Transport  Supports physical-layer implementations for SONET/SDH, SD/HD/3G-SDI and Fibre Channel with on-chip RAM for buffering and protocol handling.
• PCI Express and Server Infrastructure  Enables PCIe PHY and protocol offload and custom I/O expansion in server or storage controllers using family-level PCIe support.
• High-speed Serial Protocol Bridges  Suitable for bridging and protocol conversion tasks requiring multigigabit serial links and programmable equalization/pre-emphasis.

Unique Advantages

• High Logic Density: 228,000 logic elements enable large-scale custom logic implementations and complex system integration on a single device.
• Substantial Embedded Memory: Approximately 17.5 Mbits of on-chip RAM reduces external memory dependence for buffering and large LUT-based structures.
• High-Speed Serial Capability: GT transceivers supporting up to 11.3 Gbps deliver the bandwidth required for modern serial links and protocol stacks.
• Extensive I/O: 654 I/O pins provide flexibility for multiple interfaces, wide buses, and system-level integration without external multiplexing.
• Industrial Temperature Range: −40 °C to 100 °C rating supports deployment in industrial environments where thermal resilience is required.
• Low-Voltage Core Operation: Narrow core supply range (920 mV–980 mV) that aligns with power-optimized system designs.
