Fabricated on a 65 nm TSMC low-power process, it operates from a 1.1 V core supply and supports internal clock frequencies up to 500 MHz, making it a flagship device for high-throughput DSP, serial connectivity, and embedded processing subsystems. An FPGA (Field Programmable Gate Array) is a programmable semiconductor containing an array of configurable logic blocks (CLBs), dedicated DSP slices, embedded memory, high-speed transceivers, and a programmable interconnect fabric. FPGAs sit between microcontrollers and ASICs in the silicon hierarchy: microcontroller -> microprocessor -> programmable logic -> FPGA -> ASIC. They are selected when designers need hardware-level parallelism and deterministic latency but cannot justify the NRE cost of a custom ASIC, and they are widely used in telecommunications infrastructure, high-performance computing, test and measurement, and aerospace/defense applications. The EP3SE80F780C3 integrates 3,200 Logic Array Blocks, up to 1,440 Kbits of MLAB memory, 270 embedded 18x18 multipliers, and Stratix III's signature Programmable Power Technology that dynamically lowers supply voltage on quiescent logic tiles. Hard IP blocks include PCI Express Gen1/Gen2 endpoints, multi-gigabit transceivers (per package variant), external memory interfaces supporting DDR/DDR2/QDRII, and dedicated PLL/DLL clock management. Designers target the device with Altera's Quartus II design suite, which provides IP cores, timing analysis, and the PowerPlay power optimization flow. Typical applications span high-speed serial protocol bridging, digital video broadcast head-ends, software-defined radio baseband processing, military radar front-end preprocessing, ASIC prototyping, and high-end medical imaging pipelines. Its 488 user I/O pins and abundant vertical migration paths within the Stratix III E family also make it a strong fit for production systems that previously used multiple smaller FPGAs to reach equivalent logic density. When designing with the EP3SE80F780C3, allocate sufficient PCB layers (typically 12+ layers with dedicated power and ground planes) to route the 780-ball FineLine BGA at 1.0 mm pitch, follow Altera's Stratix III pin connection guidelines for unused transceiver and clock pins, and use the Quartus II Early Power Estimator before board layout to validate thermal budgets. Stratix III E devices are also NRND - confirm lifetime-buy options with Intel/Altera before starting new designs. This page consolidates distributor pricing, drop-in vertical-migration alternatives within the Stratix III E family, and practical Quartus II design notes not found in the standalone datasheet, giving engineers a single reference for sourcing, replacement, and bring-up decisions.

The Intel (formerly Altera) EP3SE80F780C3N is a high-density, low-power Field Programmable Gate Array (FPGA) from the Stratix III family, integrating 80,000 logic elements, 3200 Logic Array Blocks (LABs), and 488 user I/Os in a 780-pin FineLine Ball-Grid Array (FBGA-780) package. Built on a 40 nm TSMC process, this device targets performance-critical applications requiring transceiver-rich I/O, on-chip memory, and DSP blocks at commercial 0°C to 85°C operating temperature. What is an FPGA? A Field Programmable Gate Array is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and dedicated hard IP blocks (memory, DSP, transceivers, PLLs) that can be reconfigured by the designer after manufacture. FPGAs sit between general-purpose microcontrollers (sequential, software-defined) and Application-Specific Integrated Circuits (ASICs) (fixed-function, high-volume) in the programmable-logic hierarchy: PLD -> CPLD -> FPGA -> SoC FPGA. They are widely used for hardware acceleration, high-speed signal processing, and prototyping ASICs. Key features include up to 488 user I/Os, embedded TriMatrix memory blocks, dedicated DSP blocks for high-throughput arithmetic, MultiTrack interconnect for predictable timing closure, and support for high-speed external memory interfaces including DDR3. The 'C3' speed grade places this device in the mid-tier performance bin, and 'N' suffix indicates lead-free / Pb-free assembly. Internal logic-array frequency is rated to 800 MHz in this family, and fabric performance scales with design and routing constraints. Typical applications include high-speed networking line cards, wireless baseband processing, military radar and electronic-warfare signal chains, medical imaging accelerators, ASIC prototyping, and high-performance computing offload engines. The large logic capacity and abundant I/O make it well suited to data-path-heavy designs that would otherwise require multiple smaller FPGAs. When designing with this part, plan power-rail sequencing carefully - Stratix III requires multiple supply rails (VCC, VCCPD, VCCPT, VCCA, VCCH, VCCL) with strict monotonic-ramp requirements. Use the Quartus II PowerPlay early-power estimator before PCB layout to avoid thermal redesigns late in the cycle. JTAG, MSEL, and configuration-pin planning should follow the Stratix III Handbook reference schematics verbatim for first-pass board success.
EP3SE80F780C4 - Stratix III E 80K LE FPGA, 488 I/O, FCBGA-780 | Altera
The Altera (Intel) EP3SE80F780C4 is a high-density Stratix III E family Field Programmable Gate Array (FPGA) housed in a 780-pin FC-FBGA (FCBGA-780) package.

A Field Programmable Gate Array (FPGA) is a programmable semiconductor device that allows engineers to implement arbitrary digital logic through configurable logic blocks (CLBs/LABs), programmable interconnect, block RAM, DSP blocks, and high-speed transceivers. FPGAs occupy the highest flexibility tier of the programmable logic taxonomy: programmable logic → programmable logic device → semiconductor IC. Stratix III devices added Altera's Programmable Power Technology, allowing unused logic blocks to consume less power while active blocks run at full speed, addressing the historical ASIC-vs-FPGA trade-off. Key features of the EP3SE80F780C4 include 80,000 logic elements, 488 user I/Os (largest I/O count in the Stratix III E family 780-package options), 6.5 Mbit embedded memory, and selectable core voltage for low-power operation. The device supports up to 8 PLLs and multiple high-speed I/O standards including LVDS, making it suitable for high-throughput parallel interfaces. Operating temperature grade is commercial (0C to +85C), denoted by the C4 speed/temperature code. The architecture uses a tiered interconnect (HyperFlex-equivalent not present in Stratix III) combined with DSP blocks and TriMatrix on-chip memory to deliver high DSP throughput. Programmable Power Technology combined with selectable core voltage (1.1 V nominal, optionally 0.9 V for lower power) gives the lowest static power in its class for 65 nm high-performance FPGAs. Typical applications include high-performance digital signal processing, telecom baseband and packet processing, ASIC prototyping, high-end test and measurement instrumentation, broadcast video processing, and high-bandwidth data acquisition systems. The 488 I/O count supports wide parallel buses, multi-channel LVDS interfaces, and memory-rich designs. When designing with this FPGA, pay close attention to the large BGA thermal envelope and PCB stack-up requirements - 780-pin FC-FBGA requires microvia stack-up and controlled-impedance routing. Use Altera/Intel Quartus II software with the Stratix III device support to compile, simulate, and configure the device via JTAG or active serial configuration schemes.

EP3SE80F780C4L - 80K LE Stratix III E FPGA 780-FCBGA | Intel
The Intel (formerly Altera) EP3SE80F780C4L is a Stratix III E family Field-Programmable Gate Array (FPGA) housed in a 780-ball Fine-pitch Chip-Scale Ball Grid Array (FC-FBGA) package, fabricated on a 65 nm process node and supplied at 0.9 V core. It delivers 80,000 logic elements, 6,843,392 bits of embedded memory, and 488 maximum user I/O pins, with a maximum internal clock frequency of 375 MHz. The 780-FCBGA package exposes 24 full-duplex transcever lanes operating up to 6.375 Gbps for high-speed serial connectivity. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), embedded memory, DSP blocks, and programmable interconnect, all of which an engineer can reconfigure after manufacture to implement any digital circuit. FPGAs sit hierarchically between general-purpose microcontrollers (fixed architecture, software-driven) and application-specific integrated circuits (ASICs, fixed function), offering hardware-level parallelism and the ability to ship a generic silicon platform that is customized per end-product. The Stratix III E family targets high-performance, high-bandwidth applications such as wireline telecom, high-end DSP, and ASIC prototyping. Key differentiating features include 3200 Logic Array Blocks (LABs), 4 phase-locked loops (PLLs), 8.34375 Gbps maximum transceiver data rate, 488 user I/Os, and hard memory controllers. The device also integrates dedicated DSP blocks, high-speed transcevers, and the Adaptive Logic Module (ALM) architecture, which delivers roughly twice the logic capacity per LUT compared with the prior Stratix II generation. This combination of logic density and high-speed serial I/O targets throughput-intensive designs. Architecturally, the Stratix III E ALM is an 8-input adaptive structure that can be split into smaller LUTs, providing superior logic packing versus fixed 4-input LUTs. The transceiver tiles support multiple protocol Physical Coding Sublayers (PCS) including PCI Express Gen1/Gen2, Serial RapidIO, XAUI, CEI-6G, and SDI, removing the need for external PHY chips. The 65 nm process and 0.9 V core supply minimize dynamic power, while programmable power-rail gating lets unused logic cut quiescent draw, enabling the E family to hit higher performance at lower watts than Stratix II. Typical applications include high-speed serial protocol bridging (PCIe, XAUI, SRIO), ASIC and SoC prototyping, telecommunications line cards, military radar signal processing, broadcast video processing, and high-performance DSP accelerators. The 488 I/O pins and 24 transceiver channels also suit it to multi-port packet processors. Designers building high-throughput parallel pipelines benefit from the combination of ALM logic density, embedded RAM, and hard DSP blocks. Designers using this part must observe Stratix III E power-on sequencing (1.0 V, then VCCPD, then VCCAUX, then core VCC), ensure transceiver reference-clock jitter meets the protocol requirement, and respect FPGA-JTAG configuration timing during board bring-up. The device ships in the C4 (commercial, speed grade 4, enhanced power) variant with the C4L suffix denoting a lead-free / RoHS-compliant FC-FBGA package. This page synthesizes distributor pricing, drop-in alternatives drawn from the same Stratix III E family and pin-compatible cross-brand FPGAs, and practical design notes that go beyond what the manufacturer datasheet alone provides.
EP3SE80F780C4LN - 80K LE Stratix III E FPGA, 488 I/O, FCBGA-780
The Intel (formerly Altera) EP3SE80F780C4LN is a high-density Stratix III Enhanced family Field-Programmable Gate Array (FPGA) delivering 80,000 logic elements, 3,200 Logic Array Blocks (LABs), and 6,843,392 bits of embedded memory in a 780-ball Fine-pitch Chip-Scale BGA (FC-FBGA) package. Operating on a 0.9 V core supply and fabricated on a 65 nm process node, the device supports up to 488 user I/O pins and is rated for the commercial temperature grade. The "C4" speed grade and "LN" lead-free, RoHS-compliant suffix identify a specific performance/reliability bin aimed at cost-sensitive high-volume designs. An FPGA is a programmable logic device that allows hardware designers to implement arbitrary digital circuits using a matrix of configurable logic blocks (CLBs), embedded memory, DSP blocks, and high-speed transceivers, all wired together by programmable routing. FPGAs sit alongside microcontrollers, ASICs, and ASSPs in the broader semiconductor/programmable logic taxonomy and are typically chosen when design requirements include high parallelism, evolving standards, or low-volume customization that cannot be cost-justified on a custom ASIC. The Stratix III generation introduced the Programmable Power Technology, allowing unused logic and routing tiles to be powered down to reduce dynamic consumption. Key features include a maximum internal operating frequency of 375 MHz, six independent I/O bank groups, support for multiple I/O standards (LVDS, LVTTL, LVCMOS, SSTL, HSTL), and dedicated 18x18 hardware multipliers. The device integrates 18x18 multipliers, embedded memory blocks (M9K/M144K), and an extensive configuration infrastructure (active serial, passive parallel, fast passive parallel) tailored to high-throughput compute and signal-processing workloads. Hardware support for PCI Express Gen1, Gigabit Ethernet, and DDR2/DDR3 external memory interfaces is enabled through hard IP blocks. The EP3SE80F780C4LN is built on TSMC's 65 nm low-power process and is part of the broader Stratix III E family that scales from ~40K to ~120K logic elements. Compared with later Stratix IV/V families it lacks the higher transceivers-per-cm² density and the dedicated variable-precision DSP blocks, but it remains a low-cost option for legacy industrial, test & measurement, and prototyping platforms where the Quartus II design environment still fits the engineering workflow. Typical applications include high-speed digital signal processing (DSP), telecom baseband/protocol bridging, ASIC prototyping, industrial control and machine vision, and high-performance data-acquisition front ends. The 488 I/Os also make it a strong fit for display controller glue logic and broadcast video processing. When designing with this device, allocate sufficient PCB area for the FCBGA-780 footprint (29 mm × 29 mm body, 1.0 mm ball pitch), follow Intel's power-decoupling reference design, and validate the chosen speed grade against worst-case timing in Quartus II.

EP3SE80F780C4N - Stratix III E FPGA 80K LE 780-FBGA | Intel
The Intel (formerly Altera) EP3SE80F780C4N is a high-density Stratix III E Field Programmable Gate Array (FPGA) with 80,000 logic elements, 3,200 Logic Array Blocks (LABs) and 488 user I/Os, fabricated on a 65 nm process and supplied in a 780-ball FineLine BGA (FC-FBGA) package with 0.9 V core and 1.1 V I/O operation. A Field Programmable Gate Array (FPGA) is a programmable logic device (PLD) whose logic fabric, routing and I/O are configured by the user after manufacture. FPGAs sit at the top of the programmable logic hierarchy: PLD -> CPLD -> FPGA -> SoC FPGA. They are used wherever application-specific logic, DSP, or high-speed serial I/O must be implemented without the cost and lead-time of an ASIC. The Stratix III E family, of which EP3SE80F780C4N is a member, targets high-end DSP, communication and signal-processing designs. Key features of the EP3SE80F780C4N include 80,000 logic elements, 6,843,392 bits of embedded memory (M9K/M144K TriMatrix blocks), 3,200 LABs, up to 488 user I/Os, and integrated transceivers/multipliers typical of the Stratix III E family. The 65 nm process enables higher density and lower static power than previous Stratix generations, while the 780-ball FC-FBGA supports dense board layouts with controlled-impedance signal routing for memory and LVDS interfaces. The architecture combines a logic fabric based on Adaptive Logic Modules (ALMs) with TriMatrix interconnect, dedicated DSP blocks, embedded memory and a flexible clock network. This allows the EP3SE80F780C4N to implement wide datapath designs such as baseband processing, video pipelines and protocol bridging while maintaining deterministic timing closure through the Quartus II timing analyser. Typical applications include wireless baseband and backhaul, high-performance digital signal processing, military radar and SDR prototyping, ASIC prototyping, test and measurement instrumentation, and high-speed memory interfaces. The wide I/O count and high logic density make it a common choice where multiple processor cores, memory controllers and custom logic must coexist on one silicon device. When designing with this device, allocate sufficient PCB area for power decoupling and use Altera's Stratix III power-estimator early in the schematic phase, because dynamic current at high toggle rates can exceed the conservative spreadsheet value. Vertical migration within the 780-pin BGA is supported, which lets designers reuse the same PCB layout across EP3SE50, EP3SE80, EP3SE110 and similar devices. This page synthesises distributor pricing, vertical-migration drop-in alternatives in the Stratix III E family and design notes not found in the standalone datasheet.
EP3SE80F780I3 - 80K Logic Elements FPGA | Altera | Digital Systems
Altera EP3SE80F780I3 is a Stratix III E field-programmable gate array with 80,000 logic elements, 6,843,392 memory bits, and 488 user I/O pins, supplied in a 780-ball FCBGA package. The verified distributor listing identifies the device as an FPGA, while secondary specification data reports an internal frequency of 800 MHz, 0.9 V supply voltage, and a 0°C to 85°C operating-temperature range. These values should be confirmed against the original Altera datasheet before design release. A field-programmable gate array is a programmable semiconductor containing configurable logic, memory resources, interconnect, and input/output blocks. FPGA devices sit within the broader hierarchy of programmable logic devices, digital integrated circuits, and semiconductors. Unlike a fixed-function application-specific integrated circuit, an FPGA can be configured after manufacturing, allowing designers to implement changing digital functions, interfaces, and data-processing pipelines without fabricating a new silicon device. The headline capacity of EP3SE80F780I3 is its 80,000 logic elements, supported by 6,843,392 memory bits and 488 user I/O pins. The large I/O count is significant for parallel data acquisition, communications equipment, industrial controllers, and test systems that need many external connections. The 780-ball FCBGA package provides a high-density surface-mount solution, but it also requires controlled PCB assembly, exact land-pattern compliance, and careful signal-integrity planning. The reported 800 MHz internal frequency indicates substantial digital processing capability, although the achievable system clock depends on the selected configuration, logic implementation, routing, and timing constraints. The 0.9 V supply voltage is consistent with a low-voltage, high-performance FPGA architecture. Designers must use the manufacturer power guidelines and perform board-level decoupling, distribution, and thermal analysis rather than assuming that the stated internal frequency can be sustained in every design. Typical applications include high-performance digital signal processing, communications infrastructure, industrial automation, video and imaging interfaces, test and measurement equipment, and reconfigurable computing. Its 488 user I/Os make it particularly relevant when a design must bridge many buses, converters, memories, or control interfaces. The 80,000 logic elements and reported 6,843,392 memory bits provide a useful resource baseline for partitioning datapaths, control logic, packet processing, and protocol bridges. A key design trade-off is package and power complexity. The 780-ball FCBGA footprint may create routing constraints, assembly yield concerns, and demanding power-delivery requirements. Engineers should validate pin assignments, configuration circuitry, clock distribution, decoupling, and thermal performance against the manufacturer documentation before beginning PCB layout. Secondary sources report an FBGA-1152 designation for the same search result, which conflicts with the primary distributor listing of 780-BBGA/FCBGA; the package designation must therefore be resolved from the official ordering information and package drawing. This page combines verified distributor identification, package and capacity details, application context, and explicit uncertainty markers. It does not infer missing timing, transceiver, voltage, or compliance specifications. Engineers can use the comparison and design sections to organize validation work, while the official manufacturer datasheet remains the controlling source for pinout, electrical limits, timing, configuration, and assembly requirements.

The combination of 80K logic elements and 6.8 Mbit embedded RAM enables large packet buffers and FFT scratchpad memories without external SRAM, while the 488 I/O support enables direct connection to DDR/DDR2/QDR II memories and parallel ADC/DAC interfaces. When designing with this FPGA, ensure power-rail sequencing respects the 1.1 V core / auxiliary supply relationship defined in the datasheet, and that the board's decoupling network meets the transient current demands of simultaneous logic-switching events. Programming via JTAG or the active serial configuration scheme requires a Quartus II-supported configuration device.

According to the Stratix III Device Handbook, this device belongs to the performance-optimized E family targeting high-speed parallel processing, DSP-intensive designs, and memory-rich applications, with a maximum core clock performance of approximately 717 MHz. A Field-Programmable Gate Array (FPGA) is a programmable semiconductor device built around a matrix of configurable logic blocks (CLBs), programmable interconnects, and dedicated hardware blocks such as DSP slices, block RAM, PLLs, and high-speed transceivers. FPGAs sit at the top of the programmable logic hierarchy above CPLDs, enabling system architects to implement custom processor pipelines, hardware accelerators, and interface bridges that would otherwise require ASIC-level integration. The Stratix III family specifically uses a 40 nm process node and a programmable power technology that dynamically scales voltage and frequency per logic region to balance throughput and leakage. Key features of the EP3SE80F780I4L include 3200 LABs (Logic Array Blocks), 488 user I/Os, six full-duplex clock PLLs, 384 embedded multipliers (18x18), and support for external memory interfaces such as DDR3, DDR2, QDRII+, and RLDRAM II via dedicated PHY circuitry.

Architecturally, the Stratix III E family uses Altera's adaptive logic modules (ALMs) - each ALM contains an 8-input fracturable look-up table, two dedicated adders, and shared arithmetic carry chains - which roughly double the effective logic capacity per LAB compared with prior generation Stratix II devices. The 780-FCBGA package provides high signal integrity for parallel memory buses and backplane connectivity, and supports industrial temperature operation (the I4L suffix denotes industrial-grade, low-power, speed grade 4). Typical applications include high-performance computing (HPC) nodes, software-defined radio (SDR) baseband processing, high-resolution video broadcast routers, ASIC prototyping emulators, 10G/40G line-card packet processing, and military/aerospace image processing platforms. The combination of 80K LEs and 6.8 Mbits of block RAM makes the EP3SE80F780I4L a strong fit for designs that need large on-chip buffering without external SRAM. When designing with this FPGA, allocate at least 10 layers of PCB stack-up with dedicated ground and power planes around the 780-ball BGA to control simultaneous-switching-noise on the 488 user I/Os. Use the Quartus II PowerPlay early power estimator before pin assignment to verify thermal envelopes - a fully utilized Stratix III E can reach 15 W without transceivers, exceeding the 780-FCBGA thermal limit without enhanced bottom-side thermal management. This page synthesizes distributor pricing, same-family Stratix III drop-in alternatives, and practical design notes not found in the manufacturer datasheet.

Architecturally, the Stratix III E family uses Altera's adaptive logic module (ALM) building block, an 8-input fracturable LUT that can be reconfigured to implement any 7-input LUT or two independent 4-input LUTs. Combined with dedicated 18x18 multipliers, MLAB memory, and high-speed serial transceivers, the EP3SE80 enables DSP-intensive designs, memory-rich packet processing, and protocol bridging without external logic. The 780-FCBGA package provides ample signal integrity for high-speed DDR/DDR2/QDR II memory interfaces and LVDS-based chip-to-chip links. Typical applications for the EP3SE80F780I4LN include wireline telecommunications line cards, military and aerospace signal processing, high-performance DSP prototyping, broadcast video processing, and ASIC prototyping for system architects who need >70 KLE in a single device. The industrial temperature range also suits ruggedized computing and test-and-measurement platforms. When designing with this part, pay careful attention to power-rail sequencing for the 0.9 V core, 1.1 V PLL, and 1.8/2.5/3.3 V I/O banks, and follow Altera's Stratix III PowerPlay guidelines to estimate junction temperature with the device's thermal model. Designers new to Stratix III should use the Quartus II design software for synthesis, place-and-route, and timing closure.

EP3SE80F780I4N - Stratix III E FPGA 80K Cells 780-FCBGA | Intel
The Intel EP3SE80F780I4N is a high-performance, low-power Field Programmable Gate Array from the Stratix® III E family, integrating 80,000 logic elements, 488 user I/Os, and up to 6,843,392 bits of embedded memory in a 780-ball FineLine Ball-Grid Array (FCBGA). Manufactured on a 65 nm process node with a 1.1 V core supply, the device targets throughput-critical applications where deterministic performance, abundant DSP blocks, and high-speed transceivers are required. The part operates across the industrial temperature range and is rated for speeds up to 450 MHz fabric operation. A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and dedicated hard-IP blocks such as memory, DSP slices, PLLs, and high-speed transceivers. FPGAs belong to the broader class of programmable logic devices (PLDs), which sit between fixed-function ASICs and software-defined processors in the design hierarchy. The Stratix III E family specifically targets high-end digital signal processing, wireline communications, and military/aerospace systems where Stratix III GX-style transceiver-equipped cousins are not required. Key features include 3,200 Logic Array Blocks (LABs), 488 user I/Os, 6.8 Mbit embedded RAM, embedded DSP blocks for fixed- and floating-point arithmetic, programmable power technology that dynamically scales voltage and frequency per tile, and a comprehensive hard-memory controller subsystem. The 780-ball FCBGA package offers dense board integration with controlled-impedance signal escape, suitable for high-speed parallel interfaces such as DDR3, QDRII+, and RLDRAM II. Multi-gigabit transceivers are absent on the -E sub-family; designs requiring 6 Gbps+ serial links should evaluate Stratix III GX or Stratix IV parts instead. Architecturally, Stratix III E uses the Altera Adaptive Logic Module (ALM) - an 8-input fracturable LUT that can be partitioned into smaller LUTs to improve logic utilization. Combined with the programmable power technology and 65 nm low-power process, the family delivers high DSP throughput at substantially lower dynamic power than the preceding Stratix II. The device supports configuration via passive serial, fast passive parallel, and JTAG, with on-chip decompression and encryption via the advanced encryption standard (AES). Typical applications include high-performance digital signal processing for radar and electronic warfare, wireline backplane aggregation, test and measurement instrumentation, ASIC prototyping, and high-end image processing pipelines. Industrial and defense integrators value the combination of large logic capacity, abundant DSP resources, and military-grade temperature support. When designing with this device, pay close attention to power integrity - the FCBGA requires a multi-layer PCB with dedicated power and ground planes, and decoupling must follow the Stratix III Power Distribution Network design guidelines. Configuration scheme and pin assignments must be locked early in the design cycle because the 780-ball BGA footprint limits PCB rework options.

EP3SL110F1152C4N - Stratix III L FPGA, 107.5K LE, 1152-FCBGA | Intel
The Intel EP3SL110F1152C4N is a high-density Stratix III L Field Programmable Gate Array (FPGA) delivering 107,500 logic elements and 4,992,000 bits of embedded memory, housed in a 1152-ball FineLine Ball Grid Array (FCBGA) package. Operating at core speeds up to 500 MHz with 744 user I/O pins, the part is fabricated on a TSMC 65 nm low-power process and is rated for commercial temperature operation. An FPGA (Field Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and dedicated hard IP such as block RAM, DSP blocks, and high-speed transceivers. Stratix III L is positioned in the Stratix III family hierarchy below the Stratix III E and above the Cyclone III families; it targets mid-density logic designs with low-power focus, with Stratix III E optimized for memory-rich applications and Cyclone III for cost-sensitive low-density designs. Key specifications include 744 maximum user I/O, 4,992,000 embedded RAM bits distributed across M9K and M144K blocks, 432 DSP blocks for fixed- and floating-point arithmetic, and 12 phase-locked loops (PLLs) supporting multiple clock domains. The device supports LVDS, LVTTL, LVCMOS, and SSTL I/O standards across 24 I/O banks, and integrates twelve 3.125 Gbps transceivers for high-speed serial connectivity. The Stratix III L architecture combines 65 nm process geometry with a programmable power technology that enables fine-grained power gating of unused logic, fabric, and transceivers. This results in static power roughly 50% lower than the prior Stratix II generation. The device integrates hard memory controllers, PCIe hard IP, and 8-input adaptive logic modules (ALMs) that implement any 6-input LUT plus two registers, maximizing logic utilization at the highest density. Typical applications include high-performance DSP for wireless baseband, radar and imaging signal processing, high-speed protocol bridging (PCI Express, Serial RapidIO, Gigabit Ethernet), ASIC prototyping, and test and measurement instrumentation. The device is widely used in defense, aerospace, and high-performance computing domains where logic density and signal-integrity performance outweigh power and unit cost. When designing with this part, ensure PCB layout follows Intel's FCBGA escape routing guidelines for the 1.0 mm ball pitch, including microvia stack-ups and matched-length trace tuning for LVDS and transceiver channels. Thermal management requires attention because 65 nm Stratix III devices under heavy utilization can exceed 10 W dissipation and demand a thermal relief copper pour under the package.
