EP2SGX90FF40C5NES - 90nm Stratix II GX FPGA 90,960 Cells | Altera
The Altera (now Intel) EP2SGX90FF40C5NES is a high-density Stratix II GX Field-Programmable Gate Array built on a 90 nm CMOS process, integrating 90,960 logic cells (4,828 Configurable Logic Blocks) with embedded transceivers and 1.2 V core operation in a 1,508-pin flip-chip BGA (FC-FBGA) package. It targets high-speed serial I/O and DSP-intensive applications, delivering up to 609.76 MHz core performance, multi-gigabit transceivers, and on-chip memory suitable for wireline, wireless backhaul, and high-end ASIC prototyping designs. The 1.2 V core supply, together with dedicated PLL and I/O banks, allows deterministic performance for clock-sensitive data-path logic. A Field-Programmable Gate Array (FPGA) is a reconfigurable integrated circuit whose logic fabric, routing, and I/O cells are defined at design-time by the user's bitstream rather than at wafer fab. Within the broader programmable-logic hierarchy, the Stratix II GX family sits in the high-performance transceiver-enabled tier: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit -> semiconductor. The 'GX' suffix denotes integrated multi-gigabit transceivers, distinguishing the family from transceiver-less Stratix II 'E' variants and positioning the device above CPLD and low-density FPGA families such as Cyclone II in both logic capacity and serial bandwidth. Key features include 90,960 equivalent logic elements, 4,828 CLBs, embedded transceiver channels capable of multi-gigabit serial rates, dedicated DSP blocks for high-throughput arithmetic, and 90 nm process technology. The Stratix II GX architecture introduces an 'adaptive logic module' (ALM) that combines adaptive LUT and register structures, giving roughly 50 percent greater logic efficiency than previous-generation ALMs. The 1,508-pin FC-FBGA package provides high signal and power-pin density, which is essential for routing the parallel I/O, transceiver lanes, clock tree, and power rails without compromising signal integrity. Architecturally, the device combines a logic fabric of ALMs, embedded M512/M4K/M-RAM memory blocks, and DSP blocks arranged in columns. Multi-gigabit transceivers (CMU channels) sit on the periphery, supporting standard serial protocols and reference-clock forwarding, while PLLs generate the on-chip clocking backbone. The 90 nm process enables higher integration and lower dynamic power per MHz than older 130 nm or 180 nm nodes, although static power at 1.2 V core is non-negligible in dense designs. Typical applications include high-speed serial interface bridging (PCI Express, Serial RapidIO, XAUI, Fibre Channel), wireless baseband signal processing, high-definition video processing, and ASIC prototyping. It is also widely used in telecom line cards, military/aerospace signal processing, and test-and-measurement instrumentation where reconfigurable logic with on-chip transceivers reduces bill of materials. When designing with this device, plan for a robust multi-rail power architecture: 1.2 V core, dedicated PLL analog supply, transceiver supply, and reference-clock supply each require low-noise LDOs and decoupling. Use Altera's Quartus II design suite for synthesis, place-and-route, and timing closure, and consult the Stratix II GX Device Handbook for transceiver PCB layout guidelines. This page consolidates distributor pricing, package-level information, and design guidance for engineers evaluating the EP2SGX90FF40C5NES, including drop-in alternatives from the Stratix II GX family and comparable high-density FPGAs.

It is built on a 90 nm process and features adaptive logic modules (ALMs) that replace the older 4-input LUT architecture, delivering finer-grained logic packing and higher effective logic density per die area. A Field-Programmable Gate Array (FPGA) is a reconfigurable integrated circuit containing programmable logic blocks, routing interconnect, and embedded hard IP such as transceivers, block RAM, and DSP blocks. FPGAs sit within the semiconductor hierarchy as programmable logic devices -> reconfigurable digital ICs -> integrated circuits, and are used for prototyping, signal processing, and ASIC replacement where high parallelism, deterministic latency, or post-fabrication design changes are required. Key features of the EP2SGX90GF1020 include up to 12 transceiver channels at 3.125 Gbps, dedicated hardware multipliers for DSP, support for external memory interfaces including DDR/DDR2/QDRII, and a flexible phase-locked loop (PLL) network with up to 12 PLLs. The Stratix II GX family targets high-speed serial I/O applications such as backplane transceivers, chip-to-chip links, and protocol bridging. Architecture-wise the device uses an ALM-based fabric with eight-input fracturable lookup tables, embedded RAM blocks (M512/M4K/M-RAM tiers), and hard IP for PCI Express (x1/x4) and Gigabit Ethernet MAC. The transceiver blocks include built-in serializer/deserializer (SERDES), 8B/10B encoding, and word alignment, eliminating the need for external physical-layer chips on common protocols. Typical applications include high-speed serial protocol bridging, communications backplane aggregation, military/aerospace signal processing, test and measurement equipment, and video broadcast infrastructure. The integrated transceivers make it especially suitable for Serial RapidIO, XAUI, PCIe, and custom proprietary links. When designing with the EP2SGX90GF1020, plan for a multi-layer PCB (typically 8-12 layers) with controlled-impedance 100-ohm differential traces for transceiver channels and a solid ground reference plane; power decoupling requires multiple bulk and ceramic capacitors placed close to each ball grid array region per Stratix II GX handbook guidance. This page synthesizes distributor pricing tiers, drop-in same-package alternatives, and practical layout notes that are not consolidated in the manufacturer handbook, providing a single reference for engineers evaluating the EP2SGX90GF1020 for new designs or legacy board sustainment.
EP3C10E144C7 - 10K LLE Cyclone III FPGA | Altera Corporation
The Altera Corporation EP3C10E144C7 is a Cyclone III field-programmable gate array with 10,320 logic elements, 94 user I/O, 423,936 embedded-memory bits, and a 144-LQFP exposed-pad package. It combines programmable digital logic, embedded memory, PLL support, DSP-oriented embedded multipliers, and serial connectivity in a low-power FPGA platform for industrial, communications, and embedded control systems. The EP3C10E144C7 is programmed through the Quartus II design environment and supports the DSP Builder workflow for designs interfacing with MathWorks Simulink and MATLAB. A field-programmable gate array, or FPGA, is a programmable semiconductor whose digital logic and interconnect resources can be configured after manufacture. An FPGA belongs to the broader logic-device hierarchy and can function as a configurable parallel processor, interface controller, data acquisition engine, or embedded signal-processing system. Unlike a fixed-function application-specific integrated circuit, an FPGA allows logic, memory interfaces, and peripheral behavior to be updated by loading a configuration bitstream. The supplied manufacturer and distributor records identify 10,320 logic elements, 94 I/O, 423,936 embedded-memory bits, and the 144-LQFP exposed-pad package as the principal device characteristics. The exposed pad provides a direct thermal path from the FPGA to the PCB copper when the package is properly assembled. Its 94 I/O support connections to external memory, sensors, communications transceivers, converters, and control peripherals, while the embedded multipliers accelerate suitable DSP operations. Cyclone III devices combine configurable logic with on-chip memory resources and dedicated clock-management functions. PLL specifications are described in the Cyclone III device documentation, while the embedded multipliers support DSP applications. Programmable logic allows engineers to implement parallel data acquisition, protocol conversion, state machines, filtering, and control functions in one device instead of combining several fixed-function components. Typical uses include industrial automation, communications infrastructure, embedded instrumentation, video and image processing, digital signal processing, and control systems. The same EP3C10E144C7 can serve as a controller beside external DDR memory, as an interface between sensors and a host processor, or as a dedicated DSP accelerator. Quartus II and DSP Builder provide the design, compilation, and simulation workflow for these systems. A critical implementation consideration is exposed-pad soldering and thermal design. The pad should be connected to a grounded copper area using the manufacturer-recommended land pattern and assembly process. Signal integrity also depends on controlled-impedance routing for external memories and high-speed interfaces, with input/output placement and clock planning performed in the FPGA design tools. This page combines the verified distributor specification, the manufacturer datasheet link, sourcing information, drop-in family comparisons, and practical FPGA implementation guidance. It distinguishes confirmed EP3C10E144C7 data from parameters that require confirmation in the manufacturer device documentation before schematic release or production procurement.

FPGAs sit hierarchically between ASICs (Application-Specific Integrated Circuits) and CPLDs (Complex Programmable Logic Devices), offering higher density than CPLDs and far lower NRE cost than ASICs - making them ideal for low- to mid-volume designs, prototyping, and time-to-market-critical applications. Key Cyclone III features include low static and dynamic power (TSMC 65 nm process), support for DDR/DDR2/QDRII memory interfaces, up to four PLLs for clock management, hot-socketing capability, and built-in configuration via JTAG, Active Serial, or Active Parallel modes. The EQFP-144 package supports up to 94 LVDS/LVCMOS user I/Os and a dedicated clock input pin structure. Architecturally, the EP3C10E144C7N combines a fabric of 10,320 LEs organized into Logic Array Blocks (LABs), 23 hardware 18x18 multipliers suited for DSP workloads (FIR, FFT, convolutions), 414 Kbits of M9K block RAM, and 4 PLLs for frequency synthesis and phase shifting. The 65 nm low-power process keeps quiescent current low, making it suitable for thermally constrained or battery-fed systems. Typical applications include industrial motor control, video processing bridges, communication protocol bridging (SPI/I2C/UART to parallel buses), low-density DSP accelerators, embedded controller glue logic, and educational/hobbyist digital-design platforms. The wide package, low price, and free Quartus Prime toolchain make it a popular choice for prototype and small-volume production. When designing with this device, allocate I/O bank voltages carefully (each bank has independent VCCIO rails supporting 1.2V/1.5V/1.8V/2.5V/3.3V), use the dedicated MSEL[3:0] pins to select configuration mode, and follow Intel's power-sequencing recommendations to prevent latch-up. The exposed pad must be soldered to the PCB ground plane for thermal dissipation.

EP3C10E144C8 - 10K-Cell Cyclone III FPGA | Altera | 144-Lead
Altera EP3C10E144C8 is a Cyclone III FPGA with 10,320 logic elements, 94 user I/O, and a 144-lead exposed-pad LQFP package. The device is manufactured on a 65 nm CMOS process and is designed for low-power, cost-sensitive embedded applications requiring programmable logic, parallel interfaces, control, and moderate signal-processing capability. The verified distributor information identifies the EP3C10E144C8 as a Cyclone III Field Programmable Gate Array in a 144-LQFP Exposed Pad package, with 10,320 logic cells and 94 I/O. One distributor listing reports an operating frequency of 472.5 MHz, while another technical listing reports 402 MHz; the available data does not establish the exact speed-grade context for each figure. A field-programmable gate array is a semiconductor whose digital logic and connectivity are configured after fabrication. FPGAs belong to the programmable-logic device hierarchy, combining configurable logic elements, programmable interconnect, memory resources, and user I/O in one device. Compared with a fixed-function microcontroller, the EP3C10E144C8 allows hardware parallelism, custom interface timing, and logic behavior to be changed without changing the PCB. Compared with an application-specific integrated circuit, it offers a shorter path to a customized implementation for prototypes and moderate-volume products. The Cyclone III family combines 10,320 logic elements with a package offering 94 user I/O according to the verified distributor specification. The EP3C10E144C8 includes an exposed thermal pad in the 144-lead package, which requires attention to PCB thermal design and soldering. The device uses 65 nm CMOS technology and is specified as an FPGA with 10,320 cells. Its performance and I/O characteristics make it appropriate for industrial control, communications, instrumentation, consumer electronics, and embedded processing systems. Typical uses include programmable control logic, data acquisition, protocol bridging, sensor aggregation, motor and machine control, and low-cost embedded systems. The parallel structure of an FPGA can reduce dependency on multiple discrete logic devices and can simplify timing-constrained interface designs. Designers should select the correct Cyclone III device, pin assignment, configuration source, and I/O standard for the target board. The key design consideration is that replacing an FPGA is not automatically a drop-in substitution. A candidate must use the same physical package and meet the voltage, configuration, I/O, timing, and pin-mapping requirements of the original design. The EP3C10E144C8 should therefore be evaluated as a board-level device, not merely by logic-cell count. Verify the exact pinout, exposed-pad layout, power rails, decoupling, and configuration scheme against the manufacturer documentation before layout release. This product page consolidates verified distributor specifications, source links, package details, pricing observations, and practical replacement criteria. It also distinguishes confirmed EP3C10 family candidates from candidates whose resource count or grade differs, helping engineers narrow a drop-in replacement without overlooking FPGA-specific compatibility constraints.
EP3C10E144C8N - 10K LE Cyclone III FPGA, 144-LQFP | Intel / Altera
The Intel / Altera EP3C10E144C8N is a low-cost, low-power Cyclone III Field-Programmable Gate Array (FPGA) providing 10,320 logic elements, 423,936 bits of embedded memory, and 94 user I/O in a 144-pin LQFP Exposed Pad package. Operating at the commercial speed grade 8 with a commercial (0C to +85C) junction temperature rating, this device leverages a 65 nm TSMC process and targets cost-sensitive, high-volume designs where board space, power budget, and unit cost dominate the trade-off matrix. The 'C8' suffix denotes the speed grade, while the 'N' indicates a lead-free, RoHS-compliant package finish, and the '144' prefix specifies the LQFP-144 pin count. Cyclone III FPGAs occupy the entry-to-mid tier of the Altera/Intel programmable logic family hierarchy, sitting below the Cyclone IV and Cyclone V families in process node and absolute performance, but offering an unusually competitive dollar-per-logic-element ratio. The EP3C10E144C8N specifically is positioned for glue logic, custom peripheral interfacing, LED and video signal conditioning, motor control coprocessors, and mid-complexity DSP pipelines. Its built-in 18x18 multipliers, embedded RAM blocks, and PLL-based clock management make it well suited to small signal-processing farms where the flexibility of an FPGA outperforms a fixed-function MCU. The 144-pin LQFP with exposed pad provides a robust thermal path for the device's sub-watt typical power envelope and supports hand-solderable prototyping on 0.5 mm-pitch PCBs. Integrated features include 66 (7 for 9-bit) embedded 18x18 multipliers, two PLLs, and up to 414 Kbits of M9K block RAM distributed across the fabric. Designers benefit from Quartus II / Quartus Prime support, a mature IP library, and reference designs covering Nios II soft-core integration. Typical applications include industrial control and machine vision front-ends, low-cost video processing (e.g., LCD timing controllers and HDMI bridge boards), consumer electronics requiring custom I/O expansion, low-bandwidth software-defined radio front-ends, and educational / university FPGA training platforms. The exposed-pad LQFP package is especially useful for designs that need a 1.0 mm-pitch SMT footprint without the routing complexity of fine-pitch BGA alternatives. When designing with this part, allocate adequate copper area under the exposed pad for thermal dissipation and ensure I/O bank voltages match the 1.2 V / 2.5 V / 3.3 V supported standards. Engineers migrating from Cyclone II should note the 65 nm process change and updated configuration scheme, which requires a fresh Quartus project compilation. According to the Altera Cyclone III Device Handbook, configuration is supported via JTAG, Active Serial (EPCS), or Passive Serial modes, with dedicated MSEL[3:0] strap pins selecting the mode at power-up.
EP3C10E144I7 - Cyclone III FPGA, 10K LE, 144-LQFP | Intel
The Intel (formerly Altera) EP3C10E144I7 is a low-cost Cyclone III FPGA delivering 10,320 logic elements, 423,936 bits of embedded memory, and 23 embedded 18x18 multipliers in a 144-pin EQFP/LQFP-Exposed-Pad package. Built on a 65nm process and rated for the industrial temperature range (-40C to +100C), the device targets cost-sensitive high-volume applications where FPGAs were previously uneconomical. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be reconfigured after manufacturing. Within the broader semiconductor taxonomy, FPGAs sit alongside ASICs, microcontrollers, and DSPs in the programmable logic domain, which itself belongs to the larger class of logic ICs and integrated circuits. Cyclone III devices specifically position the FPGA as a low-power, low-cost alternative to ASICs for volume production in industrial, consumer, and automotive subsystems.

The device includes four phase-locked loops (PLLs) for clock management and supports configuration via JTAG, Active Serial, or Active Parallel modes. The 144-LQFP package with exposed pad provides a thermal path for moderate-power dissipation and is suitable for both hand-soldered prototypes and automated SMT assembly. Cyclone III architecture uses a four-input LUT-based logic element, embedded memory blocks (M9K) that can be configured as RAM, ROM, or FIFO, and dedicated multiplier blocks for high-performance DSP pipelines. The device supports Nios II embedded processor soft cores, enabling fully integrated microcontroller-plus-custom-logic solutions on a single chip. Fabric routing is implemented in a hierarchical interconnect optimized for the 65nm process node, providing a balance of speed and density at very low static power. Typical applications include industrial motor control, video processing bridges, low-cost protocol bridging (PCI to local bus, UART to memory), consumer display controllers, and education/DIY development platforms. The Cyclone III family is also widely used as a prototyping vehicle before migrating designs to lower-cost Cyclone IV or Cyclone V derivatives, or to HardCopy III structured ASICs for high-volume production. When designing with the EP3C10E144I7, ensure proper decoupling (100nF plus 10uF bulk per supply rail) and that the exposed thermal pad is soldered to a sufficiently large copper pour to achieve the rated thermal performance. Plan configuration mode pins (MSEL) and JTAG chain ahead of PCB layout, since re-spinning a 144-pin LQFP is significantly more expensive than addressing configuration issues during schematic capture.

Typical applications include industrial motor control (using the embedded multipliers for FOC algorithms), video surveillance image processing, automotive infotainment prototyping, low-cost software-defined radio front-ends, and display controllers for industrial HMMIs. The device's embedded M9K memory blocks efficiently buffer video line storage, while the PLLs synthesize the pixel clock from an external reference. When designing with this FPGA, pay attention to the bank-by-bank I/O supply voltage configuration, use the Quartus II (or newer Quartus Prime) toolchain for synthesis, place decoupling capacitors near each VCCINT/VCCIO supply pin, and follow the exposed-pad PCB layout guideline for the EPAD thermal dissipation pad. Consider migrating to the Cyclone IV E (EP4CE10) family for new designs because Cyclone III is approaching end-of-life.

It is built on a 60 nm process and is targeted at cost-sensitive applications where the high transceiver count and transceiver rate of mid-range Cyclone IV/V devices are unnecessary, but where a flexible programmable fabric is still required. A Field Programmable Gate Array (FPGA) is a type of programmable logic device that allows designers to configure the device's logic blocks, routing, and I/O behavior after manufacture. Within the programmable logic hierarchy, FPGAs sit at the top, above CPLDs (Complex Programmable Logic Devices), and are used to implement everything from simple glue logic to complete processor subsystems, DSP pipelines, and high-speed interface bridges. Key features of the EP3C10F256C6 include 23 embedded 18x18 multipliers, 2 PLLs for clock management, support for LVDS, LVCMOS, SSTL, and HSTL I/O standards, and a core voltage range that enables operation from typical 1.15 V to 1.25 V supplies with I/O voltages scalable to 3.3 V. It uses SRAM-based configuration, requiring an external configuration memory such as the EPCS4 or EPCS16 serial flash, and supports JTAG and Active Serial (AS) configuration modes. The device is fabricated on TSMC's 60 nm low-power process and consumes approximately 120 mW of static power under typical conditions, with dynamic power scaling with toggle rate and design utilization. Designers can use the free Quartus II Web Edition (and later Intel Quartus Prime Lite) toolchain to synthesize, place-and-route, and program the device using Verilog HDL or VHDL. Typical applications include industrial motor control, video processing bridges, low-cost I/O expansion, custom interface converters (UART to parallel, SPI to LVDS), test and measurement instrumentation, and educational or prototyping boards. The 256-FBGA package offers sufficient I/O density for mid-complexity designs while remaining hand-reworkable with proper hot-air rework equipment. When designing with this part, pay careful attention to decoupling: place 100 nF and 10 uF capacitors within 5 mm of every VCCINT and VCCIO pin pair, and follow Altera's Cyclone III hardware design guide for the PCB footprint. The configuration scheme (AS vs JTAG) must be selected via MSEL[3:0] pins during board bring-up. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical Quartus II design notes that complement - rather than duplicate - the manufacturer datasheet.
EP3C10F256C6N - Cyclone III FPGA, 10K LE, 256-BGA | Intel / Altera
The Intel (formerly Altera) EP3C10F256C6N is a Cyclone III family low-power Field-Programmable Gate Array (FPGA) housed in a 256-ball FineLine BGA package. It integrates 10,320 logic elements (LEs), 423,936 bits of embedded memory, and 182 user I/O pins, delivering a balanced logic/memory ratio for cost-sensitive programmable logic designs. The device is fabricated on TSMC's 65 nm low-power process and targets static power consumption roughly 25 percent lower than the previous Cyclone II generation, making it well suited to thermally constrained embedded systems. 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 blocks such as block RAM, DSP multipliers, and high-speed transceivers. The FPGA occupies the top of the programmable logic hierarchy, sitting between fixed-function ASICs and software-driven microcontrollers. FPGAs belong to the broader category of programmable logic devices (PLDs), which also include older CPLD architectures; an FPGA provides finer-grained logic, more embedded memory, and parallel DSP capability, while a CPLD delivers faster, deterministic non-volatile boot. In a complete embedded system, an FPGA typically handles parallel data-path processing, custom interface bridging, or hardware acceleration alongside a host processor. Key features of the EP3C10F256C6N include 182 maximum user I/Os supporting LVTTL, LVCMOS, SSTL, and differential LVDS signalling, two PLL blocks for flexible clock synthesis, and an on-chip configuration controller that supports JTAG (IEEE 1149.1), Active Serial (AS), and Active Parallel (AP) configuration modes. The device also provides up to 46 embedded 18x18 multipliers for DSP, supporting common fixed-point filtering and FFT workloads without external arithmetic accelerators. Architecturally, the Cyclone III device is built around LABs (Logic Array Blocks) containing 16 LEs each, routed through a multi-level interconnect with predictable timing closure. Hard IP blocks include M9K memory blocks (each 9 Kbit) that can be cascaded to implement FIFO, ROM, RAM, or dual-port buffers. Two dedicated PLLs provide frequency synthesis, phase shifting, and clock de-skew, simplifying board-level clock-tree design for protocols such as DDR/DDR2 SDRAM. Typical applications include industrial control and motor-drive interfaces, video/display bridging and image preprocessing, low-cost software-defined radio (SDR) baseband blocks, ASIC prototyping, and custom peripheral expansion for microcontrollers. The wide I/O count also makes it suitable for parallel data acquisition, custom bus bridges, and educational development boards. When designing with the EP3C10F256C6N, supply all four VCCINT/VCCIO banks with properly decoupled bulk and ceramic capacitors, and route configuration signals (nCONFIG, nSTATUS, CONF_DONE) carefully away from switching I/O to avoid false reconfiguration. Leave at least 30 percent of logic utilization free for place-and-route closure, and verify pin assignments in Quartus II pin-planner before layout sign-off. This page synthesises distributor pricing as of 2026-09-09, drop-in alternative candidates, and practical design notes not collated in the manufacturer datasheet, giving procurement and design engineers an AEO-optimised reference in one place.
EP3C10F256C7 - 10,320-L Logic Element Cyclone III FPGA | Altera
Altera EP3C10F256C7 is a Cyclone III field-programmable gate array with 10,320 logic elements, 423,936 memory bits, and 182 user I/O in a 256-LBGA package. It operates from a 1.15 V to 1.25 V supply and supports operation from -40 C to +125 C, making it suitable for industrial, communications, control, and embedded-processing systems. An FPGA is a programmable digital integrated circuit containing configurable logic, memory, and I/O blocks. Unlike a fixed-function application-specific integrated circuit, a Cyclone III FPGA allows designers to implement parallel processing, interface bridging, protocol handling, and custom control logic in one device. The EP3C10F256C7 belongs to the Cyclone III product family, positioned between small CPLDs and larger FPGAs. Principal device attributes include 10,320 logic elements, a listed 402 MHz switching-rate figure, 182 I/O, embedded PLL capability, and 423,936 memory bits. Its 256-LBGA package provides a dense surface-mount footprint for multilayer printed circuit boards. The listed operating-temperature range of -40 C to +125 C supports temperature-tolerant industrial deployments when the complete board, power system, and external components are also qualified. Programming and configuration determine the logic implemented in the FPGA's programmable fabric. Designers should verify power sequencing, configuration interface timing, bank-supply requirements, clocking, and I/O standards against the complete Cyclone III device documentation for the selected density, speed grade, and package. Because a BGA package does not expose a conventional lead-by-lead schematic symbol, board layout, via-in-pad requirements, solder-mask design, and assembly profiles should be validated against the official package data. Typical uses include industrial control and data acquisition, communications line cards, parallel sensor aggregation, embedded video or image processing, protocol bridges, and programmable logic for test equipment. The 182 available I/O permit simultaneous connections to external converters, memories, transceivers, and microcontrollers, while the internal logic and memory blocks support parallel pipelines and state-machine-intensive designs. A critical design consideration is that logic, memory, PLL, and I/O resources must be verified against the target clock rate before schematic capture. Engineers should also confirm configuration flash or cable compatibility, provide decoupling close to each supply ball, and plan thermal and via routing for the 256-ball footprint. This product page consolidates verified distributor specifications, source-linked pricing, same-package replacement candidates, and practical FPGA integration considerations that are not presented together in a single manufacturer datasheet.
EP3C10F256C8 - 10,320-Cell FPGA, 182 I/O | Intel | Industrial
The Intel EP3C10F256C8 is a Cyclone III field-programmable gate array (FPGA) with 10,320 logic elements, 182 user I/O, and a 256-LBGA package. It is manufactured on 65 nm technology and is associated with a 402 MHz device performance figure and a 1.2 V core supply in the verified comparison data. A field-programmable gate array is a reconfigurable digital semiconductor that belongs to the FPGA family of programmable logic devices. An FPGA sits within the broader hierarchy of programmable logic ICs, semiconductor integrated circuits, and digital logic devices. Unlike a fixed application-specific integrated circuit, an FPGA allows engineers to implement digital logic, interfaces, and parallel processing functions through a programmable configuration rather than a custom ASIC layout. The EP3C10F256C8 combines 10,320 logic elements with 182 I/O in a compact 256-LBGA package. These figures make it suitable for systems requiring a substantial programmable-logic resource count without moving to a larger FPGA. The 65 nm process generation reflects the Cyclone III family’s emphasis on power efficiency and moderate system cost. The listed 402 MHz performance and 1.2 V core voltage provide concrete references for clocking and power-design planning. The 182-I/O configuration is particularly useful for parallel buses, data converters, memory interfaces, industrial control logic, and communication peripherals. Because the device is supplied in a ball-grid-array package, PCB layout must include escape routing, via-in-pad considerations, and thermal analysis. Its 256 terminals provide the physical connection density required by a high-I/O device, although the exact function assigned to each ball is determined by the completed design and pin assignment. Typical Cyclone III FPGA applications include industrial automation, embedded control, networking infrastructure, communications equipment, and test-and-measurement systems. The device can consolidate control logic, interface adaptation, and parallel processing that might otherwise require several programmable or fixed-function devices. Engineers must still confirm whether a specific protocol, memory interface, clocking arrangement, and I/O standard are supported by the selected Cyclone III variant. A key design consideration is that the 1.2 V core requirement must be separated from any external interface supplies required by the board. Decoupling, clock jitter, I/O standards, configuration storage, and thermal performance should be validated against the manufacturer datasheet before layout release. Because the verified data does not provide a complete pricing table, detailed timing grades, or the complete 256-ball pin map, those values should be confirmed with the manufacturer or an authorized distributor before procurement.

Cyclone III is the third-generation low-power FPGA family from Altera/Intel fabricated on a 60 nm process, sitting in the broader taxonomy of programmable logic devices (PLD) -> field-programmable gate array (FPGA) -> low-power FPGA -> SRAM-based FPGA -> semiconductor IC. It is engineered specifically for low static and dynamic power dissipation while integrating sufficient logic, memory and DSP resources to displace ASICs and ASSPs in volume production. Key features of the EP3C10F256C8N include 23 embedded 18 x 18 multipliers (about 0.5 M Gates of equivalent logic), support for external memory interfaces such as DDR/DDR2/QDRII SRAM, embedded PLL-based clock management, Nios II soft-core processor compatibility, and the standard Altera Quartus II design flow. The device is RoHS-compliant, lead-free, and operates over the commercial 0 C to 85 C junction temperature range. Technically, the EP3C10F256C8N integrates 10,320 logic elements organized into 645 LABs, 414 Kbits of embedded RAM (M9K blocks), 23 dedicated 18 x 18 multipliers for DSP, and four PLLs. The 256-pin FineLine BGA provides 182 general-purpose user I/Os supporting LVDS, LVCMOS, SSTL and other single-ended and differential I/O standards with hot-socketing capability and configurable drive strength. Typical applications include industrial motor control, video processing and display bridges, automotive infotainment (non-safety), consumer electronics control planes, communications line cards, and cost-optimized ASIC replacement. Its low power and high logic density at sub-$30 unit pricing make it suitable for both prototyping and volume production. When designing with this part, plan the power distribution network around the 1.2 V core and per-bank I/O supplies, and use the Altera Quartus II development environment for synthesis, place-and-route, and timing closure. Ensure the PCB BGA layout follows Intel's recommended 1 mm pitch escape routing and that decoupling capacitors are placed as close to the package as possible. This page synthesizes distributor pricing, verified cross-references within the Cyclone III family, and practical design notes not consolidated in the manufacturer datasheet, giving engineers a faster path to selection.

The device is supplied in an industrial temperature grade covering -40°C to +125°C and uses a lead-free surface-mount configuration. It combines programmable logic, embedded RAM, and configurable I/O in one package for compact digital control, communications, signal processing, and embedded-system designs. An FPGA is a semiconductor device whose digital logic and interconnect resources are configured after manufacture. In the product hierarchy, the EP3C10F256I7 belongs to the FPGA and CPLD class, combines with programmable logic and fixed-function blocks to form a programmable digital IC, and ultimately falls within the broader semiconductor category. Cyclone III devices support parallel hardware implementation for designs that require deterministic operation, flexible pin assignment, and field-updatable configurations.

The lead-free construction and surface-mount form also align the part with modern electronics manufacturing requirements, although complete environmental and qualification declarations must be confirmed from current manufacturer documentation. Architecturally, the part consolidates combinational and sequential programmable logic with embedded memory resources. This allows designers to implement parallel datapaths, control logic, protocol bridges, and fixed-function digital blocks without relying exclusively on a microcontroller. Compared with a soft processor implemented entirely in programmable logic, the dedicated 10,320 logic-cell and 182-I/O resource set allows the FPGA fabric to be allocated according to the target workload. Typical applications include industrial automation controllers, communications infrastructure, sensor and motion-control systems, embedded video processing, and general-purpose digital prototyping. The 182-I/O count is particularly useful for designs requiring multiple buses, parallel data acquisition, or mixed control and communication interfaces. The -40°C to +125°C industrial grade also makes the device suitable for temperature-ruggedized equipment where appropriate system-level qualification is performed. Design planning must include PCB layout for all 256 package balls even though the verified device specification identifies 182 I/O pins. Signal-integrity review, decoupling, power-supply sequencing, configuration-data implementation, and thermal analysis should follow the relevant Cyclone III hardware guidance. Confirm the exact power rails, supported I/O standards, configuration requirements, and absolute maximum ratings in the current Intel datasheet before schematic release. This product record consolidates verified distributor and manufacturer-page information with package, procurement, and engineering-selection context. It also highlights where additional data is required so engineers can distinguish confirmed EP3C10F256I7 characteristics from parameters that still require validation against the applicable device documentation.

The EP3C10U256C6 combines a reconfigurable FPGA fabric with embedded fixed-function resources, making it suitable for industrial control, communications, instrumentation, consumer electronics, and embedded processing systems. An FPGA is a semiconductor device whose digital logic and interconnect structure can be programmed after manufacture. The Cyclone III family occupies the FPGA and CPLD hierarchy within programmable logic devices, offering a practical balance between logic capacity, I/O availability, power consumption, and design cost. Unlike a fixed-function application-specific integrated circuit, an FPGA can be updated during development to add interfaces, revise control sequences, or consolidate several supporting functions into one device. The verified device data identifies 10,320 logic cells, 500 MHz operation, 65 nm fabrication, and a 1.2 V core supply. Its 256-LFBGA package provides 256 external terminals and supports compact board-level integration where routing density is important. The LFBGA form factor can also make inspection and prototype rework more demanding than a leaded package, so land-grid alignment, assembly capability, and package documentation should be checked before layout release. Cyclone III devices are commonly used where design flexibility matters more than the very highest programmable logic capacity. Typical logic blocks can implement state machines, bus controllers, data acquisition logic, protocol interfaces, and peripheral bridges. Because the exact pin assignment, memory configuration, supported I/O standards, and bank power requirements are not included in the supplied verified data, they must be confirmed against the manufacturer device documentation before schematic capture or PCB layout. The EP3C10U256C6 is appropriate for industrial automation modules, compact communications equipment, test and measurement products, video-processing interfaces, and embedded control systems. It is particularly attractive when multiple fixed functions need consolidated logic or when a late design change must be implemented without changing the PCB. Quartus compilation, pin assignment, timing closure, and programming-file generation should be performed using the supported Altera or Intel FPGA toolchain for the selected device. Power, decoupling, and pin planning are critical in a 256-ball BGA implementation. Follow the manufacturer power-supply and decoupling guidance, route each supply plane carefully, and validate signal integrity and heat dissipation on the assembled PCB. Do not infer I/O voltage limits, pin names, or power-up requirements from the abbreviated distributor listings; obtain the complete device and package documentation before design release. This product page consolidates the verified 10,320-cell, 500 MHz, 65 nm, 1.2 V, and 256-LFBGA attributes with sourcing links, application guidance, package considerations, and documented data gaps. It is intended to accelerate initial device selection while clearly separating verified specifications from information that still requires manufacturer documentation.

It is manufactured using 65 nm FPGA technology with a 1.2 V core supply. The device combines programmable logic, dedicated memory resources, and configurable I/O in one compact surface-mount package, making it suitable for embedded control, communications, industrial automation, and general-purpose programmable logic designs. A field-programmable gate array, or FPGA, is a semiconductor whose digital logic can be configured after manufacture. An FPGA belongs to the programmable-logic device hierarchy and provides a flexible alternative to application-specific integrated circuits. Designers combine lookup-table-based logic, flip-flops, block RAM, multipliers, and I/O standards in software, allowing functional revisions and product differentiation without changing the underlying silicon or PCB layout. The EP3C10U256C7 provides 10,320 logic elements and 423,936 bits of embedded memory for state machines, control logic, data buffering, packet handling, and interface bridging. Its 182 user I/O provide substantial connectivity for external memories, communications transceivers, converters, and display or industrial-control peripherals. The 256-LFBGA package supports compact surface-mount assembly while preserving high pin and I/O density. The device uses 65 nm Cyclone III FPGA technology and a 1.2 V core voltage, combining a relatively large programmable logic capacity with low-voltage operation. Because FPGA performance depends on the selected clock, I/O standard, memory configuration, and design constraints, designers should evaluate timing with their actual Quartus II implementation rather than relying on device capacity alone. The verified cross-reference data identifies the commercial EP3C10U256C6 and industrial EP3C10U256I7N as package-compatible family alternatives. Typical applications include industrial automation controllers, protocol bridges, data-acquisition systems, embedded communications equipment, motor-control interfaces, and general digital signal-processing front ends. Its 182 I/O make it especially useful where an FPGA must connect multiple sensors, converters, memories, and communication transceivers while performing real-time control or filtering in parallel. PCB design should account for the 256-ball package, power and ground distribution, decoupling near the supply pins, and high-speed routing constraints. Designers should use the manufacturer’s pin and package documentation to confirm ball assignments, voltage requirements, supported I/O standards, and exposed thermal or power-management connections before layout. This page consolidates distributor inventory, verified family cross-references, package information, pricing references, and practical replacement guidance. It is intended to help engineers identify genuine same-package alternatives while clearly separating verified facts from parameters that still require confirmation from the manufacturer datasheet.
EP3C10U256C8 - 10,320-Cell Cyclone III FPGA | Intel
The Intel EP3C10U256C8 is a Cyclone III embedded field-programmable gate array with 10,320 logic elements, 182 I/O, a 472.5 MHz maximum stated frequency, and a 256-LFBGA package measuring 14 x 14 mm with 0.80 mm pitch. The device is manufactured using 65 nm CMOS technology and operates from a 1.2 V core supply, according to the verified distributor and datasheet-index records. A field-programmable gate array is a semiconductor in which the digital logic, memory blocks, and I/O assignments are configured after fabrication. An FPGA belongs to the broader programmable-logic hierarchy, combining parallel programmable logic with fixed or configurable input/output resources. The EP3C10U256C8 therefore provides a compact platform for parallel data processing, control, interface bridging, embedded protocol handling, and general-purpose digital logic. The principal verified features are 10,320 logic elements, 182 I/O, a 65 nm CMOS process, and a 472.5 MHz frequency figure. The 256-LFBGA package also supports compact board layouts, although its 0.80 mm pitch requires fine-pitch assembly and inspection. The C8 ordering code distinguishes this configuration from other speed, temperature, and package variants, so engineers should confirm the complete ordering information before substituting related MPNs. The supplied records inconsistently describe the package terminology as LFBGA, PBGA, and UBGA while consistently identifying a 256-pin, 14 x 14 mm device with 0.80 mm pitch. The 182-I/O count describes usable signal assignments rather than the total physical ball count. Exact architecture details, memory capacity, embedded hard IP, supported interfaces, power ratings, and AC timing data were not present in the verified excerpts and are therefore not inferred here. Typical uses include industrial control, communications infrastructure, test equipment, embedded video, and general embedded processing. The device can be selected when a design needs substantially more parallel logic than a small microcontroller while retaining post-fabrication field programmability. A board-level design must also account for configuration storage, power sequencing, signal conditioning, and programming-chain implementation. The most important design precaution is to preserve the exact footprint, ball assignment, core voltage, configuration method, and speed-grade requirements. Related Cyclone III devices may share the family and 256-ball format, but a similar bill of materials does not prove that every pin, timing specification, or operating grade is interchangeable. This page consolidates verified distributor specifications, package details, sourcing links, family alternatives, and engineering-oriented selection guidance. It distinguishes verified values from missing technical fields so procurement and hardware teams can evaluate the EP3C10U256C8 without confusing near-family MPNs with guaranteed drop-in replacements.

Unlike a fixed-function microcontroller, an FPGA can implement parallel data paths, protocol bridges, signal processing, control logic, and hardware acceleration in one configurable device. The Cyclone III name identifies Intel's low-cost FPGA family. The verified device information identifies 10,320 logic cells and 182 user I/O, providing a substantial parallel-logic resource for industrial control, communications, image processing, and embedded systems. The device includes 423,936 RAM bits for buffers, lookup tables, packet storage, and data-path state. Its 437.5 MHz maximum frequency supports high-speed digital logic, although practical system performance also depends on the selected design, I/O standard, memory interface, and timing constraints. The EP3C10U256I7 uses a 65 nm process and a 1.2 V core voltage, combining a relatively compact logic implementation with a large ball-grid package. The 256-LFBGA package provides 256 physical balls and a square footprint intended for surface-mount assembly. Because the supplied source describes the package as LFBGA while another search result describes the device as UBGA, engineers should confirm the exact ball map, ball-pitch dimensions, and mechanical drawing against the manufacturer documentation before releasing a PCB footprint. Typical applications include industrial control modules, programmable logic controllers, networking interfaces, motor-control systems, data-acquisition equipment, and embedded video or image-processing designs. The 182 I/O count can support multiple external interfaces, while the logic-element and RAM resources allow parallel control and buffering functions to be consolidated into a single FPGA. PCB design should account for all 256 package balls, including power, ground, configuration pins, and user I/O. The design must provide clean 1.2 V core power, suitable I/O voltage domains, decoupling, and a compatible configuration interface. Signal-integrity, thermal, and board-layout decisions should follow the official Cyclone III device documentation rather than distributor summaries alone. This product record combines verified distributor pricing, device attributes, package information, and application-oriented engineering guidance. It also distinguishes a documented no-lead package option from broader FPGA alternatives that use different packages, densities, or architectures and therefore are not treated as drop-in replacements.

An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that allows designers to configure digital logic blocks, interconnect, and I/O after fabrication. FPGAs sit within the broader hierarchy: programmable logic -> logic IC -> integrated circuit -> semiconductor, occupying the same engineering space as CPLDs, but offering far higher logic density, embedded RAM/DSP blocks, and high-speed transceivers in larger devices. Cyclone III specifically targets cost-sensitive, power-conscious volume applications such as video processing, motor control, automotive driver assistance, and industrial communication. Key features of the EP3C120F780C7AD include 119,088 logic elements (LEs), 3,981 Kbits (approximately 498 Kbytes) of embedded RAM organized as M9K blocks, 288 18x18 hardware multipliers for DSP, and four PLLs. The device supports LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards across up to 20 global clock networks, with user I/O counts in the 400+ range depending on package pinout. Configuration is supported through JTAG, Active Serial, and Passive Serial modes, with on-chip encryption (AES) for design security. The Cyclone III architecture uses a logic-element fabric with 8-input adaptive look-up tables (ALUTs), each capable of implementing any 6-input function or two independent 4-input functions. Embedded M9K memory blocks support true dual-port, simple dual-port, and single-port modes with parity bits, enabling efficient buffering, FIFO, and shift-register implementations. The DSP blocks natively support 18x18 multiplication with optional add/subtract/accumulate, eliminating the need for soft-multiplier inference in DSP pipelines. Typical applications for the EP3C120F780C7AD span HD video bridging and image processing, industrial motor control and servo drives, automotive infotainment and driver-assistance modules, telecommunications line cards, software-defined radio (SDR) baseband, and embedded industrial protocols such as EtherCAT, PROFINET, and EtherNet/IP. The combination of high logic count, on-chip DSP, and low power also makes it suitable for portable medical instrumentation and handheld test equipment. When designing with the EP3C120F780C7AD, plan the power budget across core, I/O, and PLL rails. Use the Quartus II PowerPlay early power estimator before layout to size decoupling and rail sequencing. Maintain controlled-impedance PCB traces for high-speed LVDS links, and route clock and PLL analog supplies through dedicated ferrite filters to minimize jitter.
EP3C120F780C7N - 119K Logic Element Cyclone III FPGA | Intel / Altera
The Intel (formerly Altera) Cyclone III EP3C120F780C7N is a high-density, low-power Field Programmable Gate Array (FPGA) built on a 65 nm low-k dielectric process, delivering 119,088 logic elements, 3,981,312 bits of embedded memory, and 531 hardware multipliers inside a 780-pin FineLine BGA (FBGA) package. The 'C7' speed grade supports a core clock rate up to 437.5 MHz while operating from a 1.2 V core supply, and the 'N' suffix denotes lead-free / Pb-free terminations compliant with RoHS. Cyclone III positioned the family for cost-sensitive, high-volume applications where Cyclone II was too small and Stratix families were over-spec. A field-programmable gate array (FPGA) is a type of programmable logic device (PLD) that lets designers implement arbitrary digital logic, memory blocks, and DSP functions by loading a configuration bitstream after PCB assembly. Within the broader semiconductor taxonomy, the EP3C120F780C7N sits inside the hierarchy programmable logic -> FPGA -> SRAM-based FPGA -> low-cost FPGA. Unlike ASICs, FPGAs can be reconfigured in the field, enabling rapid prototyping, late-stage design changes, and hardware reuse across product variants without respinning silicon. Key features of the EP3C120F780C7N include up to 531 embedded 18x18 multipliers for DSP, 4 PLLs with multiple outputs, support for external memory interfaces including DDR, DDR2, and QDR II SRAM, and 8 phase-locked clock networks. The device exposes up to 429 user I/O pins depending on configuration scheme and supports hot-socketing, joint Test Action Group (JTAG) boundary-scan, and Active Serial / Fast Active Parallel configuration modes via the dedicated configuration pins. Cyclone III also introduced dedicated hard IP for PCIe Gen1 soft cores implemented in fabric. Technically, the Cyclone III architecture uses 4-input look-up tables (LUT4) clustered into logic array blocks (LABs), with embedded M9K memory blocks that can be configured as RAM, ROM, or shift registers. The 65 nm process and 1.2 V core reduce dynamic power consumption versus the prior Cyclone II generation while increasing logic density roughly 4x. The device supports LVDS, LVCMOS, SSTL, and HSTL I/O standards and provides on-chip termination (OCT) for signal-integrity-critical interfaces. Typical applications include industrial motor control and machine vision, automotive driver-assistance ADAS prototypes, video processing and broadcast equipment, software-defined radio (SDR) baseband, low-cost DSP front ends, and PCI Express endpoint cards. Designers select the EP3C120F780C7N when they need Stratix-class capacity at Cyclone-class pricing and power budgets. When designing with this part, note that 780-pin FBGA requires high-density PCB routing with microvia stack-ups, the dedicated configuration pins (nCONFIG, nSTATUS, CONF_DONE, MSEL[3:0]) must be pulled correctly for the chosen configuration mode, and unused I/O banks must be powered and grounded per the datasheet to prevent floating inputs. This page synthesizes distributor inventory data, parametric drop-in candidates, and practical layout notes that complement the official Cyclone III Device Handbook rather than replace it.
