EP4SGX360FH29I4 - Stratix IV GX FPGA 353K LE, 780-FCBGA | Intel
The Intel (formerly Altera) EP4SGX360FH29I4 is a high-density Stratix IV GX Field-Programmable Gate Array (FPGA) fabricated on a 40 nm process, integrating 353,600 logic elements and 14,144 LABs/CLBs into a 780-ball FCBGA (also listed as 780-HBGA, FC-HFBGA) package. The device delivers up to 289 user I/O pins and includes 23,105,536 bits of embedded memory, with a core voltage of 0.9 V and an industrial temperature grade (I4 = -40C to +100C junction). The 'GX' suffix denotes integrated transceivers optimized for high-speed serial I/O, making this FPGA suited for protocol bridging, DSP, and ASIC-prototyping workloads. A Field-Programmable Gate Array (FPGA) is a programmable logic device that lets designers implement arbitrary digital logic through configurable logic blocks (CLBs/LABs), routing fabric, and dedicated hard IP such as transceivers, memory controllers, and DSP blocks. Within Intel's programmable-logic hierarchy, the Stratix IV GX family sits in the high-performance mid-range tier above Cyclone but below Stratix V/Stratix 10 in process node and transceiver speed. The 40 nm node gives the EP4SGX360FH29I4 an attractive balance of logic density, power efficiency, and cost for established designs that do not need the newest transceivers. Key differentiating features include 353,600 logic elements (highest density in the Stratix IV GX family for this pin-out), integrated 8.5 Gbps multi-gigabit transceivers for PCI Express Gen2, Serial RapidIO, XAUI, CEI-6G, and CPRI links, and 14,144 LABs that map to roughly 28,000 adaptive logic modules (ALMs). Hard IP blocks for DDR3 memory controllers, embedded multipliers for DSP, and PCIe Gen2 x8 endpoints are standard. Architecturally, Stratix IV GX uses ALMs (8-input fracturable look-up tables plus dedicated arithmetic/logic), embedded 9-Kbit M9K and 144-Kbit M144K memory blocks, and per-transceiver Physical Coding Sublayer (PCS) and Physical Medium Attachment (PMA) blocks. The 0.9 V core and 1.1 V/1.5 V/1.8 V/2.5 V/3.0 V I/O banks draw power proportional to toggle rate and transceiver utilization; Quarts II power estimation should be used during design entry. Typical applications include high-speed serial interface bridging (e.g., 10G Ethernet MAC + PHY bridging), DSP accelerator cards for wireless baseband and radar, ASIC/ASSP prototyping, test-and-measurement equipment, military/aerospace signal processing, and broadcast video infrastructure where the integrated transceivers replace external PHYs. The 780-ball FCBGA supports high channel count while still permitting reflow on standard SMT lines. When designing with this part, allocate transceiver reference-clock quality carefully because jitter directly scales into output eye margins. Use Intel's Stratix IV GX Transceiver Toolkit for eye-diagram tuning and the ALTGX megafunction for protocol mapping. DDR3 interfaces should be length-matched within 25 mils of the target rank to meet tDS/tDH at 800 MHz.

When designing with this part, verify that the PCB footprint matches the 1517-ball FC-FBGA land pattern with proper microvia stack-up and that the transceiver reference clock architecture satisfies jitter requirements for the target protocol. Industrial-grade temperature range (-40C to +100C ambient, indicated by the I4 speed/temperature suffix) is appropriate for outdoor telecom and industrial deployments, but designers should review the power budgeting tool output to confirm thermal headroom under worst-case toggle rates.

EP4SGX360KF43C2 - 353K LE Stratix IV GX FPGA 880 I/O FCBGA | Intel
The Intel EP4SGX360KF43C2 is a high-density Stratix IV GX Field Programmable Gate Array (FPGA) delivering 353,600 logic elements, 14,144 LABs/CLBs, and 23,105,536 bits of embedded memory in a 1760-ball Fine-Pitch Chip-Scale Ball Grid Array (FCBGA) package rated at 0.9 V core. Built on a 40 nm low-power process, the device integrates 880 user I/O pins and high-speed transceivers optimized for serial connectivity, signal processing, and high-throughput data-path applications. An FPGA (Field Programmable Gate Array) is a semiconductor device built from configurable logic blocks (CLBs/LABs), programmable interconnect, and hardened IP such as memory blocks, DSP blocks, and high-speed transceivers. FPGAs sit within the broader hierarchy of programmable logic devices (PLDs), are classified alongside CPLDs, and occupy the high-performance tier of digital semiconductors. The Stratix IV family targets applications requiring maximum logic density combined with embedded transceivers and DSP bandwidth, bridging ASIC-class performance with field-programmable flexibility. Key features include 353,600 logic elements with adaptive logic modules (ALMs), embedded 18x18 multipliers for DSP pipelines, and dedicated transceivers capable of multi-gigabit serial protocol operation. The 1760-ball FC-FBGA package provides a very high I/O count for board-level connectivity, while 23 Mbit of on-chip RAM reduces external memory traffic for buffering and packet processing workloads. The 40 nm process delivers high core density at industry-acceptable static and dynamic power for this device class. The device architecture separates logic fabric, embedded memory, DSP blocks, and high-speed transceiver circuitry into independent columns, allowing designers to optimize floorplanning for their specific bandwidth, latency, and signal-integrity targets. PLL resources and clock networks distribute low-skew clocks across the die, and configuration is loaded via the standard Stratix IV active/passive modes including JTAG and serial configuration. Typical applications include high-speed serial protocol bridging (PCIe Gen2, SATA, XAUI, CEI-6G), digital signal processing for radar and beamforming, software-defined radio and test equipment, broadcast video processing, and high-density ASIC prototyping. The high I/O count and embedded transceiver bandwidth also make the EP4SGX360KF43C2 suitable for high-performance compute accelerators and network packet processing. When designing with this device, allocate the larger PCB area required for the 1760-ball FC-FBGA package. Use Intel's Quartus II design suite (with v13.0 or earlier service releases recommended for legacy Stratix IV support). Plan thermal dissipation carefully given the package size and core power; an adequate heatsink with thermal interface material is typically required for sustained workloads.

EP4SGX360KF43C2N - Stratix IV GX FPGA, 353K LE, 880 I/O | Intel
The Intel EP4SGX360KF43C2N is a high-density Stratix IV GX family field-programmable gate array (FPGA) fabricated on a 40 nm process node, integrating 353,600 logic elements, 23,105,536 bits of embedded memory, and 880 user I/Os in a 1760-ball flip-chip BGA (FCBGA-1760 / KF43) package. It is supplied from a 0.9 V core rail, supports industrial-grade temperature operation, and is a lead-free, RoHS-compliant device intended for high-performance digital logic, signal-processing, and serial-protocol designs. A Stratix IV GX FPGA is a programmable logic device that combines general-purpose logic fabric, dedicated DSP blocks, embedded SRAM, high-speed transceivers, and hard PCIe/clock IP into a single IC. Within the broader semiconductor hierarchy, the device sits at: FPGA -> programmable logic device -> logic IC -> integrated circuit. It belongs to the Stratix IV family and the GX transceiver sub-series, meaning the silicon integrates multi-gigabit transceivers (MGTs) capable of operating at line rates commonly used by PCIe Gen1/Gen2, Gigabit Ethernet, XAUI, Serial RapidIO, and Serial ATA, in addition to the user-programmable fabric. Key differentiating features of the EP4SGX360KF43C2N include 14,144 adaptive logic modules (ALMs) and approximately 720 DSP blocks (typical for the 360 variant), embedded transceivers supporting multiple industry-standard protocols, hard memory controllers, up to 880 user I/Os, and support for high-speed external memory interfaces such as DDR3, QDR II+, and RLDRAM II. The KF43 speed grade balances timing margin and Fmax for cost-sensitive, throughput-oriented systems. The 1760-ball FC-FBGA package uses flip-chip interconnect technology that minimizes inductance for the high-speed serial and parallel I/O. Typical applications include high-throughput digital signal processing (radar, beamforming, software-defined radio), ASIC prototyping, communication infrastructure line cards, PCIe Gen2 endpoint cards, broadcast video processing, and high-end test and measurement equipment. The combination of transceivers, large logic capacity, and substantial embedded memory allows one silicon platform to absorb functions that would otherwise require separate processors, ASSPs, and discrete memory. When designing with this FPGA, plan the power-rail network around the 0.9 V core, dedicated PLL/DSP supply pins, and the high-current transceivers separately; use the Quartus II design suite for synthesis, place-and-route, timing closure, and power estimation. The 1760-ball package requires multi-layer PCB stack-up with controlled-impedance routing for transceivers and matched-length pairs for the LVDS/DDR interfaces.
