Intel EP4SGX360KF43C3N is a Stratix IV GX field-programmable gate array with 353,600 logic cells, 141,440 CLBs as reported by distributor sources, 880 user I/O connections, and 23,105,536 bits of embedded memory. It is supplied in a 1760-ball FCBGA/BGA package. The part targets high-density digital logic, high-speed signal processing, and communications systems that require programmable hardware acceleration and substantial on-chip memory. A field-programmable gate array is a semiconductor device containing configurable logic blocks, programmable interconnects, memory resources, and specialized processing elements. An FPGA sits below application-specific integrated circuits and above fixed-function digital ICs in the programmable-device hierarchy because it can be configured after manufacturing. This makes it useful for implementing parallel algorithms, interface bridging, packet processing, and signal-processing pipelines while allowing design changes without a new silicon spin. Verified data identifies 23,105,536 memory bits, 353,600 logic cells, 141,440 CLBs, and 880 I/O pins. The 1760-ball package provides the physical interface for the device, while the programmable fabric can be adapted to different algorithms and protocols. The available source data also describes high-speed DSP blocks configurable for 9 x 9-bit, 12 x 12-bit, 18 x 18-bit, and 36 x 36-bit full-precision multipliers operating at up to 600 MHz. Architecturally, the device combines programmable logic with embedded memory and dedicated DSP capability. This combination is valuable when a design needs both dense control logic and repeatable arithmetic operations. The large memory capacity supports FIFOs, buffers, and true dual-port memory structures, while the multiplier configurations support filters, transforms, and other parallel numeric operations. The distributor data also lists a 717 MHz figure, but the exact meaning of that figure should be confirmed from the manufacturer datasheet before it is used as a system-level performance limit. Typical applications include communications infrastructure, radar and sensor processing, industrial imaging, test and measurement, and high-performance DSP systems. The device can implement parallel datapaths, protocol conversion, video or image preprocessing, and real-time control functions. Because the FPGA is programmable, design teams can modify functionality through configuration and intellectual-property changes rather than changing the component footprint. A key design consideration is the high pin count and complexity of the 1760-ball package. PCB layout, power integrity, signal integrity, thermal management, configuration, and timing closure must be planned before fabrication. The user should obtain the official manufacturer documentation and verify package dimensions, speed-grade details, supply requirements, and pin assignments before release to production. This page combines the verified distributor specifications, available source links, and a conservative replacement analysis; values not present in the supplied evidence are marked for confirmation rather than inferred.

The "C4" speed grade targets commercial-temperature applications with the standard performance tier of the family. What is an FPGA? A Field Programmable Gate Array (FPGA) is a programmable semiconductor device whose logic functionality, interconnect, and I/O behavior are configured after manufacturing by the customer using a hardware description language. FPGAs sit above general-purpose microcontrollers and ASICs in the flexibility/performance trade-off: ASICs deliver the highest performance per watt but cannot be reconfigured; microcontrollers run software but are bound to a fixed instruction set. Stratix IV family FPGAs target high-throughput signal processing, high-speed serial connectivity, and protocol bridging between ASIC/ASSP blocks. The 880 user I/Os support a wide range of single-ended and differential I/O standards including LVDS, LVPECL, HSTL, and SSTL, while the integrated high-speed transceivers enable multi-gigabit serial links such as PCIe, Serial RapidIO, XAUI, and CEI. Embedded DSP blocks operate as 9 x 9, 12 x 12, 18 x 18, and 36 x 36 full-precision multipliers at up to 600 MHz, providing a deterministic DSP fabric for FFTs, FIR filters, and modulation/demodulation blocks. Typical applications include high-end wireless baseband processing, software-defined radio (SDR), radar and electronic-warfare signal chains, medical imaging accelerators, high-performance ASIC prototyping, and 10G/40G line-card bridging. The 1760-ball FCBGA package is designed for high-density board designs using BGA assembly and controlled-impedance multilayer PCBs. Designers should plan power, decoupling, and signal-integrity analysis up front: the FCBGA-1760 package requires a multi-layer PCB with buried vias, the configuration scheme (AS, PS, JTAG, or FPP) must be selected before PCB layout, and thermal management must dissipate the device's full-load power through top-side heatsinking. This page synthesizes distributor pricing, a curated set of pin-compatible Stratix IV GX family alternatives, and practical design notes that complement - not duplicate - the manufacturer datasheet.

The embedded transceivers use dedicated clock-data recovery and serializer/deserializer blocks, freeing user fabric for application logic. On-chip memory can be configured as RAM, ROM, or FIFO, with true dual-port support on M9K blocks. Typical applications include high-speed serial interface bridging (PCIe, SATA, XAUI), wireless baseband DSP, software-defined radio, ASIC prototyping, and high-throughput network packet processing. The combination of dense logic, embedded transceivers, and abundant DSP makes the EP4SGX360KF43C4N well-suited to designs that exceed the capacity of Cyclone IV or Cyclone V families. When designing with this device, plan the power budget carefully: at full utilization the core can draw tens of amps at 0.9 V, requiring a multi‑phase VRM and substantial decoupling. Use Altera/Intel Quartus II design software (the last version with Stratix IV support) and follow AN 571 guidelines for transceiver PCB layout to maintain signal integrity at 8.5 Gbps.

The Intel (formerly Altera) EP4SGX360NF45C4 is a high-density Stratix IV GX Field-Programmable Gate Array (FPGA) integrating 353,600 logic elements, 14,144 Adaptive Logic Modules (LABs), 920 user I/Os, and 23,105,536 bits of embedded memory in a 1932-ball flip-chip BGA (FC-FBGA) package. Built on a 40nm process with a 0.9V core voltage, it delivers high-performance parallel DSP and SERDES-based transceiver capability for wired communications, signal processing, and high-throughput data-pipeline designs. A Field-Programmable Gate Array (FPGA) is a reconfigurable semiconductor whose logic fabric, routing, and I/O can be customized by the user after manufacture. FPGAs sit between fixed-function ASICs and software-programmable processors in the design hierarchy: programmable logic -> reconfigurable logic -> FPGA -> programmable logic device (PLD) -> standard logic IC. The Stratix IV family specifically combines general-purpose fabric with embedded transceivers, hard memory blocks (M20K), and DSP blocks optimized for high-bandwidth signal chains. Key features of the EP4SGX360NF45C4 include 8.9 Mbits of distributed RAM, 8 transceivers supporting multi-gigabit serial links, dedicated DSP blocks for fixed- and floating-point arithmetic, and SelectRAM+ memory architecture. The 'C4' speed grade indicates a commercial-temperature operating range, while the NF45 package designation identifies the 45 mm body 1932-ball FC-FBGA. Designers typically pair this device with DDR3/DDR2 memory controllers, multi-lane PCI Express hard IP, and SERDES reference clock networks.

Its high logic density makes it suitable for designs that would otherwise require multiple smaller FPGAs, simplifying board layout and BOM. When designing with this part, ensure a 12-layer or thicker PCB with controlled-impedance routing for SERDES lanes; also verify thermal dissipation since a 1932-ball FCBGA package concentrates significant heat flux and benefits from a heatsink or high-airflow chassis.
EP4SGX360NF45C4N - Stratix IV GX FPGA, 353.6K LE, 1932-FCBGA | Intel
The Intel (formerly Altera) EP4SGX360NF45C4N is a high-density Stratix IV GX Field-Programmable Gate Array (FPGA) integrating 353,600 logic elements, 14,144 Adaptive Logic Modules (ALMs), and 23,105,536 bits of embedded memory in a 1932-ball flip-chip BGA (FCBGA) package. Built on TSMC's 40 nm process, the device integrates up to 920 user I/Os and embedded transceivers that deliver multi-gigabit serial connectivity for high-bandwidth backplane and chip-to-chip links, while the 0.9 V core voltage keeps dynamic power consumption within the Stratix IV family's documented envelope. An FPGA is a reprogrammable semiconductor device whose logic fabric, routing, and I/O can be configured by the customer after manufacturing, which distinguishes it from an ASIC (Application-Specific Integrated Circuit) and from a CPLD (Complex Programmable Logic Device). Stratix IV GX sits at the top of the Stratix IV family hierarchy, which itself belongs to Intel's high-performance FPGA product line aimed at communications, signal-processing, and high-throughput data-acquisition systems; within that hierarchy, the EP4SGX360NF45C4N is the largest density point in the family at 353.6K logic elements. Key differentiating features include embedded transceiver channels capable of multi-gigabit-per-second operation, on-chip DSP blocks for high-throughput arithmetic, embedded memory with hardware FIFO controllers, and Partial Reconfiguration (PR) support that allows a portion of the fabric to be reprogrammed while the rest remains active. The NF45C4N speed grade corresponds to the fastest transceiver/performance bin available for this device, and the C4 commercial temperature grade (0 C to 85 C) targets controlled-environment deployments rather than industrial or military ranges. Architecturally, the device pairs an SRAM-based lookup-table fabric with 8-input fracturable ALMs, dedicated 18x18 multipliers that can be combined for higher precision, MLAB (Memory Logic Array Block) tiles, and per-channel PCS (Physical Coding Sublayer) hardware for each transceiver. Engineers typically floorplan around the transceiver locations first because of their tight PCB-routing requirements, then place the global clock network and PLL/DCM blocks before committing the remainder of the design to the standard logic array. Typical applications include high-end telecommunications line cards, radar and electronic-warfare front ends, medical imaging pipelines, broadcast video processing, high-speed test and measurement instrumentation, and ASIC prototyping. The combination of high logic density and integrated serial transceivers makes the part particularly attractive in designs that would otherwise require a discrete ASSP plus external glue logic. Designers should plan power-rail sequencing carefully: the 0.9 V core, 1.1 V PLL/SerDes analog, and 2.5 V/3.3 V I/O rails each require dedicated decoupling and POR (power-on-reset) supervision to avoid latch-up during bring-up. Decoupling must be placed as close as possible to the BGA balls, with the largest bulk capacitors on the opposite side of the PCB. This page synthesizes distributor pricing from eight authorized sources, drop-in same-package alternatives from the Stratix IV GX family, and practical design guidance that complements, rather than duplicates, the manufacturer datasheet.

The 40 nm low-power process and dedicated PLL/clock networks enable deterministic timing closure for multi-gigabit interfaces, which is critical when the FPGA drives or receives data from analog front-ends, ADCs/DACs, or backplane SERDES. Typical applications include high-end wireless baseband processing, software-defined radio (SDR) platforms, video broadcast and imaging pipelines, ASIC prototyping, and high-throughput test and measurement equipment. The combination of logic density and embedded transceivers makes it well suited for designs that previously required an ASIC plus a companion FPGA. When designing with this device, plan the PCB escape pattern for the 1932-ball FCBGA carefully, as signal-integrity routing below the package typically requires a high-layer-count board with microvias and a controlled-impedance stackup. Designers must also budget for configuration memory (EPCS) and a thermal solution capable of dissipating the worst-case transceiver-driven power. This page synthesizes Intel/Altera datasheet parameters, distributor pricing, same-brand same-package drop-in alternatives, and practical design notes for the EP4SGX360NF45I3, complementing the manufacturer handbook with structured engineering context.

The device is part of the Stratix IV GX family that integrates up to 920 user I/O pins and 14,144 LABs (Logic Array Blocks), making it one of the largest members of the family. The 'I4' speed grade and 'N' suffix denote industrial temperature range (-40 °C to +100 °C) and lead-free / RoHS-compliant packaging. What is an FPGA (Field Programmable Gate Array)? An FPGA is a programmable logic device that combines configurable logic blocks, programmable interconnect, and dedicated silicon IP such as transceivers, DSP blocks, and block RAM. Within the broader semiconductor taxonomy, an FPGA sits alongside microcontrollers, ASICs, and CPLDs in the digital logic / programmable logic category. The Stratix IV GX family specifically targets high-speed serial I/O (SERDES) applications, integrating up to 24 transceivers per device for protocols such as PCIe Gen1/Gen2, XAUI, Serial RapidIO, and CEI-6G.

An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit built from an array of configurable logic blocks (CLBs), programmable interconnects, I/O cells, and on-chip memory that the designer can reconfigure after manufacturing. Within the broader taxonomy, the EP4SGX530HH35C3 sits at the top of the programmable-logic hierarchy: FPGA -> programmable logic device (PLD) -> digital logic IC -> integrated circuit. Stratix IV GX specifically targets applications that require both massive parallel logic capacity and multi-gigabit transceivers on a single die. Key features include 24 full-duplex CDR-capable transceivers with embedded 8B/10B encoders/decoders compliant with IEEE 802.3-2005 Gigabit Ethernet, ±100 ppm clock compensation, and receiver synchronization state machines. The device integrates hard PCIe Gen1/Gen2 IP blocks, up to 1024 multiplier blocks (18x18) for DSP, and PLLs with fractional-N support. Hard memory controllers and 4.5 Mb of TriMatrix embedded memory per logic array block deliver deterministic low-latency data movement. Architecturally, Stratix IV GX uses a 40nm low-power CMOS process with adaptive logic modules (ALMs) that implement 8-input fracturable look-up tables, providing an effective 1.4x density gain over previous generations. The transceiver tiles support a wide range of serial protocols including PCIe Gen2 x8, XAUI, Serial RapidIO, and 10G KR backplanes. Typical applications include 40G/100G optical line-card prototyping, radar and DSP front-ends, ASIC prototyping emulators, and high-frequency trading accelerator cards. The combination of transceivers, DSP blocks, and abundant external memory bandwidth makes this device well-suited to signal-processing workloads. A key design consideration is PCB layout: the 1152-ball FCBGA requires a multi-layer board with microvia stacks, controlled-impedance transceiver channels, and careful power-plane decoupling to meet 8.5 Gbps signal-integrity margins.

A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose digital logic function is defined by the user after manufacture via a hardware description language (HDL) and a configuration bitstream. FPGAs sit between fixed-function ASICs and software-programmable processors: they deliver ASIC-class parallelism and throughput while retaining the re-programmability of software. Within the broader silicon taxonomy, an FPGA is a programmable logic device (PLD), a sub-category of logic ICs under Integrated Circuits, and ultimately a member of the power-managed semiconductor family. The Stratix IV GX sub-family specifically adds multi-gigabit transceivers for high-bandwidth serial connectivity. Key features include 8.5T transceivers on the GX variant, embedded 10/100/1000 Ethernet MACs, and an internal clock network supporting up to 800 MHz operation.

The 40 nm process technology balances performance and power consumption while delivering robust logic capacity. Typical applications include high-end communications infrastructure (40G/100G line cards, wireless baseband), real-time signal processing for radar and test & measurement, ASIC prototyping, broadcast video processing, and industrial automation requiring deterministic hardware acceleration. The 1152-ball package is also well suited for high-density parallel interfaces and memory-rich subsystems. When designing with this device, ensure the PCB provides adequate thermal dissipation given the 42.5 mm body size and use Altera's Quartus II design software (or the Intel Quartus Prime subscription) for synthesis, place-and-route, and timing closure. The C3 speed grade denotes a specific performance bin - engineers should consult the Stratix IV Device Handbook for detailed timing models.

What is a Stratix IV GX FPGA? A Stratix IV GX is a high-performance FPGA that combines logic fabric, embedded memory blocks (M9K/M144K), DSP blocks, and multi-gigabit transceivers (MGTs) on a single die. Within the broader taxonomy, the EP4SGX530HH35C4 sits at FPGA -> programmable logic -> semiconductor IC. It is engineered for wireline communications, ASIC prototyping, and high-throughput signal processing applications where both massive parallel compute and serial I/O bandwidth are required. The device features 21,248 adaptive logic modules (ALMs), 564 maximum user I/O pins, dedicated hardware multipliers and DSP blocks for fixed- and floating-point arithmetic, and eight fractional phase-locked loops. Hard PCI Express and memory controller IP cores shorten time-to-prototype for embedded systems. The HH35 speed grade and commercial 0 C to 85 C operating temperature band (-C4 suffix) target lab, prototyping, and commercial deployment workloads. Architecturally, the EP4SGX530HH35C4 exploits Altera's partial reconfiguration and the Quartus II / Quartus Prime design toolchain. Designers can configure multi-gigabit transceivers across CPRI, OBSAI, Serial RapidIO, PCIe Gen1/Gen2, and 10 Gigabit Ethernet physical layers, while programmable logic capacity supports chip-level protocol bridges and channel aggregation. Typical applications include 100G line-card forwarding engines, software-defined radio baseband processing, ASIC emulation platforms, high-frequency trading acceleration, and high-end test and measurement instrumentation. The wide transceivers also suit radar and EW signal capture backplanes. Designers should account for power-plane decoupling of the flip-chip BGA, multi-rail sequencing, and JTAG-based configuration from EPCS or external flash. The 1152-ball FCBGA package requires careful PCB stack-up planning for signal integrity across 8.5 Gbps links.
