EP2SGX90EF1152I4 Overview

The Intel (formerly Altera) EP2SGX90EF1152I4 is a high-density Stratix II GX family FPGA combining 90,960 logic elements, 4,520,448 bits of embedded memory, and integrated transceivers in a 1152-ball FC-FBGA package. It operates across an industrial temperature range (-40C to +100C ambient, I4 grade) and supports up to 558 user I/O pins. Built on a 90 nm process with a 1.2 V core supply, the device runs at a maximum internal clock frequency of 732.1 MHz, targeting high-throughput serial and parallel DSP workloads.

An FPGA (Field-Programmable Gate Array) is a programmable logic device that consists of an array of configurable logic blocks (LABs/CLBs), embedded memory blocks, DSP blocks, routing interconnects, and I/O cells - all of which can be reconfigured by the customer after manufacture. FPGAs sit between general-purpose microcontrollers and ASICs in the design flexibility-vs-performance trade-off, with Stratix II GX specifically positioned for high-speed serial connectivity (multi-gigabit transceivers) and DSP-intensive designs.

Key features of the EP2SGX90EF1152I4 include 4,548 LABs/CLBs, 452 user I/O pins, dedicated multiplier blocks and DSP hardware, 12 embedded transceivers supporting multi-gigabit serial protocols (PCI Express, Serial RapidIO, Gigabit Ethernet, XAUI), and dedicated PLL clock management blocks. The 1152-ball flip-chip BGA exposes the high I/O count and transceiver channels required for high-bandwidth parallel and serial interfaces.

The device architecture combines look-up table (LUT)-based logic with on-chip TriMatrix memory (MRAM blocks), variable-precision DSP blocks, and clock networks. The 90 nm process permits the 90K-LE density in this BGA while still meeting timing closure at hundreds of MHz, making the part a workhorse for high-end communications infrastructure, video broadcast, and defense signal-processing platforms.

Typical applications include high-speed serial protocol bridging (PCIe Gen1/Gen2 endpoints, Serial RapidIO switches, XAUI/10G Ethernet MACs), software-defined radio baseband, ASIC prototyping, ASIC and ASSP emulation, video and image processing pipelines, and high-performance DSP coprocessors. The industrial temperature grade (I4) makes it suitable for telecom, industrial, and ruggedized embedded platforms.

Designers should plan for JTAG-based configuration with the EPCS or enhanced-configuration device, use Intel Quartus II for synthesis and place-and-route, and budget careful attention to multi-gigabit transceiver PCB layout (controlled-impedance differential routing, decoupling, and ground-plane stitching). The large BGA also requires careful thermal design: expect a multi-layer PCB with at least four dedicated supply/ground planes and dozens of thermal vias under the package.

This page synthesizes distributor pricing, drop-in same-family variants, and practical design notes that complement the manufacturer datasheet. Engineers evaluating EP2SGX90EF1152I4 should review the Stratix II GX Family Datasheet and the Stratix II GX Device Handbook for full transceiver and memory interface specifications.

The industrial temperature grade (I4) supports telecom and industrial backplane deployments.

πŸ“»

Software-Defined Radio Baseband

The EP2SGX90EF1152I4 is widely deployed in SDR baseband signal processing chains because of its 90K logic elements, dedicated DSP blocks, and integrated transceivers for ADC/DAC digital interfaces or RF front-end links. The 4.5 Mbit embedded memory is sufficient for sample buffering and FFT windowing, while the high I/O count lets the FPGA interface to multi-channel ADC/DAC pairs in parallel. The 732.1 MHz internal clock rate supports wideband demodulation. The I4 industrial temperature grade is essential for outdoor or ruggedized SDR deployments in tactical and cellular infrastructure.

πŸ–₯️

ASIC Prototyping and Emulation

The EP2SGX90EF1152I4 with 90,960 logic elements is sized to map large ASIC blocks for hardware/software co-verification, often used in arrays of two or four FPGAs for million-gate ASIC prototypes. The 558 user I/O pins provide the inter-FPGA and chip-to-chip channels needed to partition a large design across multiple devices. The integrated transceivers support high-speed serial links between prototyping boards. Quartus II provides the design partitioning and pin-multiplexing tools required to map ASIC RTL onto Stratix II GX FPGAs efficiently.

🌐

High-Speed Serial Protocol Bridging

The EP2SGX90EF1152I4 supports Serial RapidIO, XAUI, 10G Ethernet MAC, and other multi-gigabit protocols using its integrated transceivers.

The EP2SGX90EF1152I4 is suited for multi-stream HD video processing because of its high DSP block count, embedded memory bandwidth, and 558 user I/O that can carry multiple DVI/HDMI/SDI data paths into the device. Real-time video scaling, deinterlacing, color space conversion, and compression (H.264/MPEG) can be implemented in logic plus DSP. The 4.5 Mbit embedded memory is used for line buffering. Industrial temperature grade (I4) supports broadcast and surveillance deployments where ambient temperatures vary widely.

🏭

Telecom and Industrial Control

The EP2SGX90EF1152I4 fits telecom line cards and industrial control systems where deterministic, low-latency logic and DSP are required alongside high-speed serial backplane links. The 90K logic elements accommodate complex state machines, protocol stacks, and DSP filters, while the integrated transceivers connect to backplane fabrics (XAUI/SFI). The I4 industrial temperature grade (-40C to +100C) meets telecom NEBS and industrial cabinet environmental specs. The 1152-FBGA is designed for high-density line-card PCB layouts.

⚑

High-Performance DSP Coprocessor

The EP2SGX90EF1152I4 can be paired with a host CPU as a DSP coprocessor for FFT, FIR, matrix multiply, or video codec acceleration, using its dedicated DSP blocks and embedded memory bandwidth. The 732.1 MHz internal clock supports sustained gigabit-rate processing. The integrated transceivers enable high-throughput host links (PCIe, Serial RapidIO) without external bridge chips. The industrial temperature grade (I4) allows deployment in outdoor or factory-floor coprocessor cards.

EP2SGX90EF1152I4 vs EP2SGX130GF1508I4 - which should I choose?
The EP2SGX130GF1508I4 offers 130K logic elements versus 90K on the EP2SGX90EF1152I4, but in a different package (1508-FBGA vs 1152-FBGA). They are NOT pin-compatible. Choose the EP2SGX130 for larger logic capacity if your PCB can accommodate the bigger package; choose the EP2SGX90 if you need a 1152-ball layout with sufficient logic for ASIC emulation. The 130-device sits in the same Stratix II GX family.
When should I choose the EP2SGX90EF1152I4 over the EP2S90F1020I4?
Choose the EP2SGX90EF1152I4 when you need integrated multi-gigabit transceivers (PCIe, RapidIO, XAUI), since it is part of the Stratix II GX family. Choose the EP2S90F1020I4 (Stratix II, non-GX) when you only need logic, memory, and parallel I/O, and are willing to use external PHY devices for high-speed serial. Both share 90K logic elements but differ in transceiver availability.
What is the best drop-in replacement for the EP2SGX90EF1152I4?
The best drop-in replacement is the EP2SGX90EF1152I3 (industrial I3 grade, same 1152-FBGA footprint). Both share identical logic, memory, and I/O resources. Other variants in the same package include EP2SGX90EF1152I2N and the EP2SGX90EF1152C5/C4/C3 commercial-grade parts. Because the part is NRD, Stratix IV GX (EP4SGX230) is the recommended migration path if a longer-lifecycle device is required.
Can the EP2SGX90EF1152I4N replace the EP2SGX90EF1152I4?
Yes. The EP2SGX90EF1152I4N is the RoHS-compliant variant of the EP2SGX90EF1152I4 in the same 1152-FBGA package, with identical 90,960 logic elements and 558 user I/O. The N suffix indicates lead-free / RoHS compliance. Either part can be used as a drop-in replacement when mechanical and thermal characteristics match the original footprint and PCB land pattern.
Where to download the EP2SGX90EF1152I4 datasheet PDF?
The official datasheet can be downloaded from Intel's Stratix II GX documentation archive at intel.com (search the litarchives/sgx2gx directory). Third-party mirrors such as GlobalSpec, FPGAkey, Veswin, and YIC Electronics also host PDF copies of the datasheet. Per Intel's documentation policy, the Stratix II GX Family Datasheet and Stratix II GX Device Handbook are the primary reference documents.
Where to find the EP2SGX90EF1152I4 pinout?
The full pinout for the 1152-ball FC-FBGA package is published in the Stratix II GX Device Handbook, Chapter 7 (Pin-Outs for Stratix II GX Devices). The 1152-FBGA is a high-density flip-chip BGA with 558 user I/O, multiple supply/ground balls, and dedicated transceiver channels. Use the Quartus II Pin Planner to assign pins, since manual reading of the BGA ball map is error-prone.

The EP2SGX90EF1152I4 is the I4 grade, with an industrial temperature range of -40C to +100C ambient (junction up to +125C). This covers most telecom, industrial, and ruggedized embedded applications. For commercial environments (0C to +85C), use the EP2SGX90EF1152C5/C4/C3 variants. The I4 grade is not AEC-Q100 qualified; this part is not intended for automotive under-hood applications.
What is the difference between EP2SGX90EF1152I4 and EP2SGX90EF1152C4?
The EP2SGX90EF1152I4 is the industrial (I4) temperature grade and the EP2SGX90EF1152C4 is the commercial (C4) temperature grade. Both share identical 90,960 logic elements, 4,548 LABs, 4,520,448 memory bits, and the same 1152-FBGA package. The only differences are the operating temperature range and any subtle timing/voltage-characterization differences between industrial and commercial silicon. They are pin-compatible drop-in replacements within their respective temperature windows.
Does the EP2SGX90EF1152I4 support PCI Express?
Yes, the Stratix II GX family integrates multi-gigabit transceivers that natively support PCI Express Gen1 (x1, x4, x8 endpoints and root ports) along with Serial RapidIO, Gigabit Ethernet, XAUI, and other serial protocols. The number of transceiver channels and maximum data rate depend on the device variant; the EP2SGX90EF1152I4 supports the standard Stratix II GX transceiver feature set.
Hey Google, what is the difference between Stratix II GX and Stratix II FPGAs?
The Stratix II GX family adds integrated multi-gigabit transceivers to the Stratix II architecture. The base Stratix II (e.g. EP2S90F1020I4) provides logic, memory, DSP, and parallel I/O but no transceivers, requiring external PHY chips for protocols like PCIe or XAUI. The Stratix II GX (e.g. EP2SGX90EF1152I4) integrates those transceivers on-die, simplifying PCB layout and reducing BOM cost for high-speed serial designs.
What are the key specifications of the EP2SGX90EF1152I4 that engineers should know?
Per Intel's Stratix II GX documentation: the EP2SGX90EF1152I4 contains 90,960 logic elements across 4,548 LABs, 4,520,448 bits of embedded TriMatrix memory, 558 user I/O, integrated multi-gigabit transceivers, a 1.2 V core supply, 90 nm process, 732.1 MHz maximum internal clock, and is housed in a 1152-ball FC-FBGA. Industrial temperature grade is -40C to +100C (I4).
What is the best Xilinx equivalent for the EP2SGX90EF1152I4?
Cross-brand equivalents are limited because the Stratix II GX family integrates multi-gigabit transceivers with a proprietary architecture. The closest Xilinx equivalents are from the Virtex-5 LXT/SXT family (e.g. XC5VLX110T, XC5VSX95T), which offer similar logic density, integrated GTX transceivers, and BGA packaging. NOTE: cross-brand FPGAs are NOT drop-in compatible at the pin level - PCB redesign is required.
What design software supports the EP2SGX90EF1152I4?
The EP2SGX90EF1152I4 is supported by Intel Quartus II (or Quartus Prime) design software, version 7.2 or later (newer Quartus versions continue to back-support Stratix II GX for legacy designs). The design flow includes synthesis (Quartus Synthesis or third-party tools like Synplify), place-and-route, simulation (ModelSim-Questa), and configuration via JTAG or EPCS configuration devices.

Engineering reference data for EP2SGX90EF1152I4 β€” comparison, design guidance, and compliance information.

Selection Guide

Choose the EP2SGX90EF1152I4 when you need a 90K-logic-element Stratix II GX FPGA with integrated multi-gigabit transceivers in the 1152-FBGA package for telecom, industrial, or ruggedized deployments where the industrial I4 temperature grade (-40C to +100C) is required. Choose the EP2SGX90EF1152C5N for commercial-temperature builds with RoHS compliance in the same footprint. Choose the EP2SGX60EF1152I4 when 60K logic elements suffice and the lower unit cost matters. Choose the EP2SGX130GF1508I4 when you need more than 90K logic elements but can accommodate the larger 1508-FBGA package. Avoid the EP2S90F1020I4 unless you specifically need the non-GX (transceiver-less) variant with external PHYs. Because the device is NRD, plan migration to Stratix IV GX or Stratix V GX for new designs.

Design Notes

The 1152-ball FC-FBGA requires a multi-layer PCB (typically 8 to 12 layers) with dedicated ground and supply planes under the package. Use a 1.0 mm or 1.27 mm pitch BGA land pattern per JEDEC MS-026. Escape routing on the top layer must fan out at 45-degree angles from each row, with via-in-pad recommended for inner rows. A minimum 4-layer stackup (SIG/GND/PWR/SIG) is acceptable for lower-speed designs, but transceiver channels require at least 6 to 8 layers with continuous ground reference planes beneath all high-speed traces.

Estimated: at full logic utilization (~80%) and 558 active I/O switching at moderate frequency, the EP2SGX90EF1152I4 dissipates roughly 5 to 8 W. The FC-FBGA package exposes the die directly to a thermal lid; use a heat sink with thermal interface material or a high-performance thermal pad. Place at least 30 thermal vias in a 1.0 mm grid under the central die area, stitching to internal ground planes. Without adequate thermal relief, junction temperature may exceed 100C in sealed enclosures.

Multi-gigabit transceiver channels require 100-ohm differential controlled-impedance routing, length matching within the transceiver-pair tolerance (typically under 5 mil), and continuous reference ground beneath each trace. Use AC-coupling capacitors at the transmitter output as required by the protocol. Decouple each transceiver supply pin with 0.1 uF and 10 uF capacitors placed within 100 mil. Avoid routing signals across plane splits near the transceiver channels, and use stitching vias every lambda/20 along the edges of the differential pairs.

The Stratix II GX device requires multiple supply rails: VCCINT (1.2 V core), VCCIO (per-bank I/O voltage, 1.2 V to 3.3 V), VCCPD (3.3 V or 2.5 V pre-driver), VCCA (2.5 V analog PLL/transceiver), VCCD_PLL (1.2 V PLL digital). Each rail must be decoupled close to its pin with bulk and bypass capacitors. Power-on sequencing requires VCCINT before VCCIO; consult the Stratix II GX Device Handbook Power Management chapter for the required sequencing and ramp rates to avoid long-term reliability issues.

Common pitfalls include (1) forgetting to release the nCONFIG pin to logic high after power-up, causing the device to remain in configuration reset; (2) omitting the JTAG chain TMS pull-up, which leaves the device in an undefined state; (3) using the wrong configuration mode (AS, AP, PS, FPP) for the EPCS device; (4) leaving unused I/O pins floating instead of setting them to tri-state with weak pull-up; (5) mixing Stratix II and Stratix II GX configuration schemes. Always verify the Quartus II device programmer recognizes the part before attempting to load a design.
