EP4SGX360FF35C2X Overview

The Intel (formerly Altera) EP4SGX360FF35C2X is a high-density Stratix® IV GX Field-Programmable Gate Array with 353,600 logic elements, 14,144 adaptive logic modules (LABs), and 23,105,536 bits of embedded memory in a 1152-ball FCBGA package. The device is built on a 40 nm CMOS process and integrates 24 transceivers supporting data rates up to 8.5 Gbps, making it a drop-in member of the Stratix IV GX family optimized for high-speed serial I/O and DSP-intensive applications.

A Field-Programmable Gate Array (FPGA) is a reprogrammable semiconductor device that combines programmable logic blocks, configurable interconnects, and dedicated hardware resources such as block RAM, DSP slices, and high-speed transceivers. Within the broader taxonomy, FPGAs sit under programmable logic devices -> logic ICs -> integrated circuits -> semiconductors. The Stratix IV family specifically targets high-performance applications including wireline communication, military radar, and high-end broadcast video.

Key features of the EP4SGX360FF35C2X include 564 user I/O pins, embedded transceivers capable of 600 Mbps to 8.5 Gbps operation, up to 1,288 18x18 multipliers for DSP, and 32 global clock networks. The device operates over the commercial 0 °C to +85 °C junction temperature range and ships in a 35 x 35 mm, 1.0 mm pitch FCBGA. Compared with later Stratix V and Stratix 10 families, this device retains the same Quartus II design flow and pin-compatible footprint options across speed grades.

The 'C2' suffix indicates the speed grade (fastest in the Stratix IV GX family) and 'FF35' designates the 1152-ball FCBGA package with FineLine BGA ball pitch. Power estimation requires Quartus II PowerPlay and depends on toggle rate, logic utilization, and transceiver activity. The 'X' suffix at the end denotes the extended industrial / commercial lead-free shipping option.

Typical applications include 40G/100G wireline framer/mapper, software-defined radio baseband, ASIC prototyping, high-resolution video processing, and DSP co-processing in test and measurement. Designers transitioning to newer Intel FPGAs should evaluate Cyclone V GX or Arria 10 for cost-sensitive designs, or Stratix 10 for higher transceiver bandwidth.

Typical Applications

EP4SGX360FF35C2X is suitable for 6 applications: 40G/100G Wireline Framer / Mapper, Software-Defined Radio Baseband, ASIC Prototyping Platform, High-Resolution Video Processing, Test & Measurement Instrumentation, DSP Co-Processing / Accelerators.

🌐

40G/100G Wireline Framer / Mapper

The EP4SGX360FF35C2X is well-suited for 40G and 100G wireline framer and mapper designs where 24 transceivers at 8.5 Gbps deliver the high-speed serial bandwidth required for OTU4, CFP, and QSFP+ interfaces. With 353,600 logic elements, the device can implement full OTN framer/mapper, FEC (forward error correction) Reed-Solomon coding, and GFP mapping in a single device without external ASSPs. Designers using this part typically run the transceivers at 8.5 Gbps to feed a CFP module, with the C2 speed grade providing margin for the 100G OTU4 43.018 Gbps aggregate data path. The 1.0 mm pitch FCBGA package enables controlled-impedance routing for the 24 transceiver channels.

📻

Software-Defined Radio Baseband

The EP4SGX360FF35C2X serves as a high-density baseband processor for software-defined radio (SDR) platforms in military and commercial wireless infrastructure. Its 1,288 18x18 multipliers provide the DSP throughput needed for LTE, WiMAX, and proprietary modulation schemes, while 23 Mbits of embedded block RAM store intermediate FFT and channelization data. The C2 speed grade ensures that FFT engines running at hundreds of MHz meet timing closure in Quartus II. The 564 user I/Os connect to ADC/DAC mezzanine cards (FMC sites) for wideband RF sampling, and 8.5 Gbps transceivers link to digital front-end ASICs or backhaul Ethernet interfaces.

🖥️

ASIC Prototyping Platform

The EP4SGX360FF35C2X is widely used for ASIC prototyping thanks to its 353K logic elements which can emulate approximately 5-10 million ASIC gates depending on RTL style. The 564 user I/Os enable prototyping of ASICs with wide external buses (DDR2/3, LVDS, parallel ADC interfaces), and the embedded transceivers prototype high-speed SerDes that would otherwise be unavailable in standard ASIC prototyping platforms. Quartus II's incremental compilation and LogicLock regions let design teams partition a large ASIC design across multiple FPGAs. The C2 speed grade provides timing margin so that emulated ASIC paths still meet real-world frequency targets.

📺

High-Resolution Video Processing

Broadcast video processing equipment (e.g. 4K/UHD up-converters, motion-compensated frame rate converters, and HDMI 2.0 routers) deploy the EP4SGX360FF35C2X as the central video pipeline controller. The 8.5 Gbps transceivers carry SDI signals (3G-SDI, 6G-SDI, 12G-SDI) and HDMI 2.0 TMDS streams, while 353K logic elements implement chroma upsampling, scaling, and frame-buffer management. Embedded block RAM (23 Mbits) holds active video line buffers and motion vectors. The C2 speed grade allows the video pipeline to operate at pixel clock rates exceeding 297 MHz for 4K60 4:2:2 workflows.

📡

Test & Measurement Instrumentation

High-end oscilloscopes, logic analyzers, and arbitrary waveform generators use the EP4SGX360FF35C2X for signal conditioning, memory control, and display pipeline functions. The 24 transceivers at 8.5 Gbps capture high-speed serial buses (PCIe Gen3, SATA III, USB 3.0) for protocol-aware logic analysis. With 564 user I/Os, the FPGA aggregates multi-channel ADC data from high-bandwidth digitizers and routes it through DDR3 memory controllers into processing pipelines. The C2 speed grade and rich DSP blocks enable real-time FFT and trigger logic for spectrum-analyzer functionality.

🏭

DSP Co-Processing / Accelerators

High-performance compute systems deploy the EP4SGX360FF35C2X as a coprocessor for DSP-intensive workloads such as radar beamforming, seismic processing, and real-time image enhancement. The 1,288 18x18 multipliers can be cascaded into 36x36 multipliers and 18x18 complex multipliers, while the embedded memory bandwidth supports streaming FFT kernels. PCIe Gen2 x8 lanes (via transceivers) link the FPGA to a host CPU for coprocessor-style workload offload. Compared to GPU or DSP ASIC solutions, the EP4SGX360FF35C2X offers lower latency and per-watt efficiency for deterministic real-time signal processing.

What is the logic element count of the EP4SGX360FF35C2X?
The EP4SGX360FF35C2X contains 353,600 logic elements organized into 14,144 adaptive logic modules (LABs). According to the Altera Stratix IV Device Handbook, each LAB contains 16 adaptive logic modules (ALMs), each ALM holding up to two 4-input LUTs plus dedicated arithmetic and shift-register logic. This high logic density targets ASIC-replacement and high-end DSP designs.
How many transceivers does the EP4SGX360FF35C2X have?
The EP4SGX360FF35C2X includes 24 embedded transceivers supporting data rates from 600 Mbps to 8.5 Gbps. These transceivers support protocols such as PCIe Gen1/Gen2, XAUI, Serial RapidIO, and CEI-6G. They are arranged in transceiver banks around the device periphery with dedicated clocking and equalization circuitry per channel.
What package does the EP4SGX360FF35C2X use?
The EP4SGX360FF35C2X is packaged in a 1152-ball FCBGA with designation FF35 - meaning 35 mm x 35 mm body, 1.0 mm ball pitch. The FineLine BGA (FCBGA) substrate provides controlled-impedance signal paths for high-speed transceivers and a large thermal slug area for heat dissipation. PCB layout requires microvia/stacked-via technology for breakout.
What is the operating temperature range of EP4SGX360FF35C2X?
The EP4SGX360FF35C2X is specified for commercial-grade operation with a junction temperature range of 0 °C to +85 °C.

As of 2026-09-10, the EP4SGX360FF35C2X shows lead times ranging from 6 to 14 weeks at major distributors, depending on stock depth. Intel/Altera has transitioned most new Stratix IV GX designs to Stratix V/10, so the EP4SGX360FF35C2X is increasingly quote-only. Designers should plan ahead and request delivery commitments in writing before issuing POs.
EP4SGX360FF35C2X vs EP4SGX360FF35C3N - which is better?
The EP4SGX360FF35C2X uses the C2 (fastest) speed grade, while the EP4SGX360FF35C3N uses the slower C3 grade. For applications where Fmax is critical (high-speed transceivers at 8.5 Gbps, tight DSP timing), the C2 offers measurable margin. For lower-cost designs not pushing the speed envelope, the C3N variant can save 20-30% on unit cost.
EP4SGX360FF35C2X vs EP4SGX230KF40C2N - which is better for my application?
The EP4SGX360FF35C2X has 53% more logic elements (353K vs 228K) and 24 transceivers at 8.5 Gbps, while the EP4SGX230KF40C2N uses a different F780 FBGA package. Choose EP4SGX360FF35C2X when maximum logic and transceiver count are required. Choose EP4SGX230KF40C2N only if your design fits 780-ball pinout - they are NOT pin-compatible.
When should I choose EP4SGX360FF35C2X over newer Stratix V?
Choose the EP4SGX360FF35C2X when (1) you have a mature Quartus II design that does not benefit from 28 nm migration, (2) your FPGA footprint in PCB layout is fixed at FF35 1152-ball, or (3) long-term availability of proven silicon matters more than 14 nm power savings. Migrate to Stratix V/10 only if you need >12 Gbps transceivers or 28 nm power efficiency.
Is the EP4SGX360FF35C2X suitable for ASIC prototyping?
Yes - the EP4SGX360FF35C2X with 353K logic elements, 1,288 DSP blocks, and 564 user I/Os is well-suited for ASIC prototyping of mid-complexity ASICs up to ~5-10 million ASIC gates. Its 8.5 Gbps transceivers enable prototyping of ASICs with multi-Gigabit SerDes interfaces. Quartus II provides soft-core IP (Nios II) for control-plane prototyping.
What is the best drop-in replacement for EP4SGX360FF35C2X?
The best drop-in replacement for EP4SGX360FF35C2X is the EP4SGX360FF35C2XG - same die, same FF35 1152-ball FCBGA package, same C2 speed grade, with the only difference being the G-suffix denoting lead-free shipping compliance. Both parts share identical pinout, BSDL model, and Quartus II device programming files, requiring zero PCB or firmware changes.
Can EP4SGX360FF35I2X replace EP4SGX360FF35C2X?
The EP4SGX360FF35I2X is pin-to-pin compatible with the EP4SGX360FF35C2X - both use the same FF35 1152-ball FCBGA. The 'I' suffix denotes industrial temperature range (-40 °C to +100 °C junction) instead of commercial (0 to 85 °C). You can drop in the I-grade variant if your application requires wider temperature operation, but expect longer lead time and higher cost.

Selection Guide

Choose EP4SGX360FF35C2X when you need the fastest Stratix IV GX speed grade (C2) with 353,600 logic elements, 24 transceivers at 8.5 Gbps, and commercial temperature range, in the FF35 1152-ball FCBGA. This part is the right answer for 100G framer/mapper, ASIC prototyping, SDR baseband, and high-end DSP where every MHz of Fmax matters. Select EP4SGX360FF35C3N if your design has margin and you want 20-30% unit-cost savings. Choose EP4SGX360FF35I2X if your deployment is outdoor, military, or industrial-temperature - same pin-out, same logic, wider junction range. Migrate to a Stratix V GX (e.g. 5SGXEA7H) only if you need >12 Gbps transceivers, 28 nm power efficiency, or new PCIe Gen3/4 IP cores. Avoid the FF35 package if your board area cannot accommodate a 35 x 35 mm FCBGA - in that case the 780-ball FF23 variant (with smaller logic density) is more appropriate.

Key Differentiators

  • C2 speed grade provides highest Fmax in the Stratix IV GX family (vs EP4SGX360FF35C3N)
  • Full industrial temperature range option in identical FF35 footprint (vs EP4SGX360FF35I2X)
  • X-suffix indicates extended lead-free and pre-bake compliance (vs EP4SGX360FF35C2XG)

Design Notes

Estimated: The EP4SGX360FF35C2X in the 35 x 35 mm FCBGA can dissipate 20-30 W depending on transceiver activity and logic utilization. At a typical theta_JA of ~3-5 °C/W (with sufficient airflow and thermal via array), the device requires a forced-air heatsink for continuous operation. A 6x6 thermal via array in the central slug region with 0.3 mm drill and 1 oz copper plating is mandatory to meet thermal design power (TDP) targets.

The 1152-ball FCBGA with 1.0 mm pitch requires high-density interconnect (HDI) stack-up with microvia-in-pad technology. Use an 8-12 layer PCB stack-up with stripline routing for transceiver channels. Each transceiver channel requires 100 ohm differential impedance with skew <5 mil. Decoupling: place 0402 0.1 µF and 0201 0.01 µF capacitors as close as possible to every power pin; bulk 22 µF ceramic capacitors on each power rail within 200 mil.

Transceiver channels at 8.5 Gbps demand a continuous reference plane with no splits under the channel routing. Use HyperLynx or SiSoft QCD/QCS for pre-route simulation of channel loss (<-10 dB at 4.25 GHz Nyquist) and crosstalk. AC-coupling capacitors (0.01 µF 0402) must be placed within 200 mil of the FPGA balls. Receiver CTLE and transmit pre-emphasis / de-emphasis should be configured per Altera Stratix IV GX Transceiver User Guide.

Do not confuse the FF35 1152-ball FCBGA package with FF31 (1517-ball) or FF23 (780-ball) - the ballout and pinout are not compatible. Always verify the exact device temperature grade ('C' = commercial, 'I' = industrial) matches your environmental requirements. When migrating from C2 to C3 speed grade, expect approximately 15% Fmax reduction; re-run TimeQuest timing analysis after recompiling. Ensure Quartus II version is 13.1 or later for full Stratix IV GX support.

Power estimation requires Quartus II PowerPlay Analyzer. Inputs: toggle rate, logic utilization, transceiver count, clock frequency, I/O activity. For an early estimate, assume 0.5 mW per logic element at 250 MHz toggle rate, plus 200-400 mW per active transceiver channel at 8.5 Gbps. The device requires multiple supply rails: VCC (core), VCCAUX (auxiliary), VCCPD (I/O pre-driver), VCCPGM (configuration), and per-bank VCCIO. Sequence VCC before VCCAUX per datasheet ramp requirements.
