The Altera (Intel) EP2AGX125DF25I5G is a member of the Arria II GX family of field-programmable gate arrays (FPGAs), delivering 118,143 logic elements, 8,315,904 bits of embedded memory, and 260 user I/O pins in a 572-ball flip-chip BGA (FC-FBGA) package. It integrates up to 12 transceivers capable of 3.75 Gbps operation and runs on a 0.9 V core supply. A field-programmable gate array (FPGA) is a reprogrammable semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and dedicated hard IP such as transceivers, DSP blocks, and embedded RAM. FPGAs sit within the programmable logic hierarchy as cousins to CPLDs and ASICs, and they are widely used to implement custom digital signal processing, high-speed serial interfaces, and glue logic without the NRE cost of an ASIC. The Arria II GX family targets mid-range applications that need a balance of logic density, transceiver bandwidth, and power efficiency. Key features of the EP2AGX125DF25I5G include 8.315 Mbits of on-chip memory (about 8.3 Mb), 576 (9-bit) embedded multiplier blocks, and 12 full-duplex transceivers with CMU, PMA, and PCS support up to 3.75 Gbps. The -I5 speed grade and industrial -40C to +100C junction temperature rating make it suitable for harsh environments, while the 572-pin FC-FBGA package supports high signal integrity for dense, multi-gigabit designs. The architecture combines a fine-grained logic fabric with dedicated hard IP blocks, reducing power versus a soft-only implementation and freeing fabric resources for user logic. Designers use Quartus II to compile, place-and-route, and program the device via JTAG or active serial configuration, allowing rapid design iteration. Typical applications include wireless baseband processing, high-speed serial protocol bridging (PCIe Gen1/Gen2, CPRI, OBSAI, XAUI, SDI), video and imaging pipelines, and industrial control planes that demand deterministic latency. The transceiver-rich fabric is particularly well matched to telecom fronthaul and backhaul. When designing with this device, plan the PCB for FC-FBGA fan-out, thermal management (multiple GND balls for the exposed die), and reference-clock distribution, because transceivers require very clean, low-jitter clocks to meet eye-mask compliance.

Key features of the EP2AGX125EF29C4G include 8 high-speed transceivers with PMA, PCS, and hard PCIe/Serial RapidIO/GIGE IP cores, dedicated DSP blocks for high-throughput multiplication, and a rich clock network with PLLs. The 'C4' speed grade balances Fmax and power for cost-sensitive designs, while the 'G' suffix indicates Pb-free / RoHS-compliant lead finish. The 40 nm process and the integrated transceiver hard IP enable low-latency serial I/O, deterministic timing closure, and reduced BOM cost relative to two-chip implementations. Designers benefit from the Quartus II design suite, a mature toolchain supporting Verilog, VHDL, and SystemVerilog with extensive IP libraries. Typical applications include PCIe Gen1/Gen2 endpoint cards, telecom backplanes with Serial RapidIO, broadcast video processing, wireless baseband pre-processing, and industrial imaging. The combination of 8.3 Mbits of RAM, DSP blocks, and high-speed transceivers makes the part well-suited to data-pipeline designs that need both parallel processing and serial connectivity. When designing with this device, pay close attention to PCB layout for the MGTP/GTX transceiver channels - controlled-impedance differential routing and tight return-path stitching are critical for 5+ Gbps signaling. Use IBIS-AMI models and Quartus transceiver toolkits during pre-layout simulation. The 780-ball FBGA requires a 1.0 mm or finer pitch PCB and high-density interconnect.

The architecture combines a power-optimized logic fabric with hard IP blocks for transceivers, PCIe, and external memory interfaces, allowing deterministic timing closure for high-throughput signal-processing applications while keeping the part within a single 780-pin FC-FBGA outline (29 mm x 29 mm, 1.0 mm pitch). The transceiver hard IP blocks implement PCS and PMA layers in silicon, offloading serialization from user logic. Typical applications include wireless baseband processing, military radar signal chains, video broadcast infrastructure, high-speed imaging, industrial test equipment, and PCIe-based coprocessor cards. The combination of transceivers, dedicated DSP blocks, and abundant block RAM makes it a strong fit for digital signal processing pipelines. When designing with this device, the PCB must implement length-matched differential pairs for all transceiver channels (typically 6 layers or more) and a 12-layer stack-up is recommended for PCIe Gen2 compliance. Quartus II design software is required for place-and-route, and IBIS models are needed for signal-integrity simulation of the LVDS/DDR interfaces.

The combination of embedded transceivers, hard PCIe IP, and abundant logic also suits the device for medical imaging pre-processing and industrial high-speed vision pipelines. When designing with this device, allocate sufficient PCB area for the 780-BGA footprint (29 mm x 29 mm) and a multi-layer stack-up (typically 8-12 layers) to maintain signal integrity on the transceiver channels. Use the Quartus II design suite (or its successor) for synthesis, place-and-route, and timing closure. For power estimation, plan for a worst-case TDP near 13-14 W; an appropriately-sized thermal solution or airflow is required in enclosed chassis.

FPGAs sit between fixed-function ASICs and software-driven processors, offering hardware-timed parallelism, deterministic latency, and field-upgradable functionality. Within the broader hierarchy, FPGAs belong to programmable logic devices -> logic ICs -> integrated circuits -> semiconductors, and are widely used to implement custom data-path, control, and interface functions before or instead of an ASIC. Key features of the EP2AGX125EF29I3 include 49,640 adaptive logic modules (ALMs), 4,964 LABs, integrated hard PCIe Gen1 controllers, dedicated 6.144 Gbps-capable transceivers, and on-chip DSP blocks for high-throughput signal processing. The 780-BGA package provides the I/O density required for high-pin-count designs while supporting high-speed serial links and parallel memory interfaces. Designers typically target the Arria II GX family when they need multi-gigabit transceivers without paying the premium for higher-end Stratix devices. Typical applications for this FPGA include high-speed serial interface bridging, video broadcast and processing equipment, telecom line cards, industrial imaging, and software-defined radio front-ends. The combination of PCIe hard IP and multi-gigabit transceivers also makes it suitable for protocol conversion cards and test-and-measurement instrumentation where deterministic, low-latency I/O is required. When designing with this device, pay particular attention to power-rail sequencing and decoupling because the Arria II GX architecture requires multiple supply rails (core, I/O, transceiver, PLL). PCB layout should follow Intel/Altera pin-out guidelines for the FCBGA-780 footprint to maintain signal-integrity on the transceiver channels. Stock at major distributors is constrained because the part is now NRND - check distributor inventory and consider EP2AGX125EF29I5 for higher speed grade if availability is limited.

The device is intended for programmable digital logic designs requiring configurable interconnect, embedded functional resources, and high-density I/O. This product-family-level summary uses the exact values available in the verified distributor and search records; detailed timing, transceiver, memory, power, and package-dimension values remain subject to confirmation from the official device datasheet. An FPGA is a semiconductor device whose digital logic, routing, and I/O behavior can be configured after manufacturing. In the system hierarchy, it sits between fixed-function application-specific integrated circuits and software-defined processing: unlike an ASIC, an FPGA can be reprogrammed, while unlike a microprocessor, it can execute many operations concurrently in configured hardware. FPGAs are commonly selected for data paths, interface bridging, digital signal processing, control systems, and prototyping. The target belongs to the Arria II GX family, a programmable-logic product family from Intel/Altera. The verified listings identify the part as an Arria II GX FPGA and expose three headline architecture values: 372 user I/O, 8,315,904 programmable bits, and 118,143 logic elements. These values indicate a high-density programmable device with a substantial I/O interface. The package is listed as 780-BBGA and FCBGA, with a ball-grid-array form factor suitable for surface mounting. The listings also identify the part as an FPGA, allowing engineers to distinguish it from fixed-function interface, memory, or power-management components. The architecture is relevant to applications that need parallel processing, configurable timing, and hardware-level interface adaptation. The 118,143 logic elements provide the programmable fabric for implementing combinational and sequential logic. The 8,315,904 programmable-bit figure describes the device's programmable configuration capacity as reported by the distributor listing. The 372 user-I/O count indicates the available external interface resources, although actual usable I/O depends on the selected package, bank assignments, configuration, and design constraints. Typical applications include communications equipment, industrial automation, test and measurement systems, and data-acquisition or signal-processing platforms. These systems can benefit from configurable hardware parallelism and interface customization. The exact transceiver count, maximum operating frequency, logic-element configuration, supported memory interfaces, and power requirements are not present in the supplied verified data, so those parameters must be confirmed from the official datasheet before implementation. Designers should verify the complete ball map, bank-specific I/O rules, configuration method, clocking resources, transceiver specifications, power rails, thermal limits, and recommended decoupling network from the official Intel documentation. The 780-ball package requires careful PCB escape routing, controlled-impedance analysis, and verification of the exact land pattern. The supplied search results are sufficient for product identification, package description, I/O count, logic-element count, programmable-bit count, and distributor availability, but not for a complete electrical design sign-off. This page combines verified distributor records, an Arria II GX datasheet reference result, and structured cross-reference search results. It is designed to help engineers identify the component and assess procurement options while clearly separating supplied facts from parameters that require additional manufacturer documentation.

EP2AGX125EF35C5G - 118K Cells, 500 MHz FPGA | Intel
Altera EP2AGX125EF35C5G is a 118,143-cell Arria II GX field-programmable gate array (FPGA) with 452 I/O, a 500 MHz stated performance point, and 0.9 V core supply operation, supplied in a 1,152-ball FCBGA/FC-FBGA package. The verified distributor data identifies an embedded FPGA with 8,315,904 programmable bits and 1,152 package terminals. This combination places the device in a high-density programmable-logic class intended for systems requiring configurable digital processing, interface bridging, and hardware-level parallelism. An FPGA, or field-programmable gate array, is a semiconductor device whose logic functionality is configured after manufacturing. In the system hierarchy, it sits between fixed-function integrated circuits and software-programmable processors: the FPGA can implement parallel digital circuits, custom interfaces, and processing pipelines, while a processor typically executes sequential software. Its configurable logic, embedded memory resources, and I/O structure allow one hardware platform to support multiple product functions or design revisions. The headline characteristics of the EP2AGX125EF35C5G are its 118,143 logic cells, 452 I/O, and 1,152-ball package. The device is listed as part of the Arria II GX family and operates from a 0.9 V supply according to the supplied distributor specifications. The package is a ball-grid-array format suitable for high-pin-count surface-mount assembly, and the device is offered in tray packaging according to the verified Arrow listing. From an architectural perspective, the density and programmable-bit count provide substantial capacity for datapath logic, control functions, memory mapping, and interface adaptation. The 452 I/O resources support communication with multiple external buses or high-bandwidth peripherals. Because the available web results provide no verified values for operating temperature range, transceiver count, memory configuration, package body dimensions, or speed grade timing, those values must be obtained from the manufacturer datasheet before final system design. Typical applications include communications equipment, industrial control, test and measurement, and embedded systems that need parallel processing or custom digital interfaces. The Arria II GX classification and 500 MHz listed specification make the part relevant to designs where deterministic hardware execution and configurable connectivity are more important than the software flexibility of a conventional processor. A modern FPGA design should also confirm device-family support in the selected development environment and validate pin assignments against the exact 1,152-ball package drawing. A key design consideration is that a ball-grid-array package requires controlled PCB layout, appropriate escape routing, thermal analysis, and reliable assembly processes. The verified data does not establish every electrical, timing, or thermal limit, so the datasheet and family documentation remain authoritative. The supplied search results also do not identify a verified pin-compatible drop-in replacement; the alternatives section therefore avoids inventing replacement claims. This page synthesizes the supplied distributor specifications, package information, pricing references, and cross-reference search results. It distinguishes verified facts from parameters requiring datasheet confirmation and provides engineering context for FPGA selection, PCB planning, and procurement decisions as of 2026-09-08.
EP2AGX125EF35C6G Arria II GX FPGA | Altera | Signal Processing
Altera EP2AGX125EF35C6G is a high-density Arria II GX field-programmable gate array with 118,143 logic elements, 8,315,904 total RAM bits, and 452 user I/O pins, supplied in a 1152-BBGA, FCBGA package. The verified package description also identifies a 1152-FBGA, 35 mm x 35 mm supplier-device format, and its core supply range is 0.87 V to 0.93 V. This combination targets data-intensive programmable logic designs requiring substantial embedded memory, extensive external interfacing, and high pin-count packaging. A field-programmable gate array, or FPGA, is a semiconductor device built from configurable logic blocks, programmable interconnects, and dedicated functional resources. In the system hierarchy, an FPGA sits between a general-purpose processor and fixed-function application-specific integrated circuits: firmware-defined logic can implement parallel processing, interface bridging, protocol handling, and digital signal processing while retaining design flexibility. Embedded RAM reduces dependence on external memory for buffers, FIFOs, lookup tables, and transient data storage. The principal verified resources are 118,143 logic elements, 8,315,904 total RAM bits, and 452 user I/O pins. The device uses 1152-FBGA packaging and supports a junction-temperature operating range of 0 °C to 85 °C. Its 0.87 V to 0.93 V core-supply range requires a tightly controlled power distribution network. These characteristics make the part appropriate for systems that need high logic density, broad memory capacity, and a large number of board-level connections. From an architectural perspective, the FPGA combines programmable logic fabric with embedded memory resources distributed throughout the fabric. Designers can instantiate parallel datapaths, state machines, communication controllers, and signal-processing structures, then route them through programmable interconnect. Because the verified data does not provide transceiver count, speed grade, logic-cell architecture detail, or maximum operating frequency, those parameters must not be inferred. Engineers should consult the complete manufacturer datasheet and device-family documentation before setting clock budgets or selecting configuration circuitry. Typical applications include real-time signal processing, industrial control, communications infrastructure, image and video processing, and high-throughput test equipment. Its 118,143 logic elements support complex parallel processing, while 8,315,904 RAM bits can hold data samples and protocol packets. The 452 user I/O pins are particularly useful where the FPGA must bridge sensors, memories, converters, network interfaces, and backplane connectors concurrently. The main design constraint is power integrity. A 0.87 V to 0.93 V core rail must use suitable regulation, local decoupling, and low-impedance PCB planes. Designers should also validate I/O banking, configuration pins, signal-integrity requirements, thermal behavior, and ball assignment against the manufacturer package documentation. The verified data does not include sufficient detail to specify those constraints numerically. This product record combines verified architecture, memory, I/O, package, supply, and temperature data with package-compatible comparison guidance and procurement references. Unlike a distributor listing alone, it distinguishes confirmed values from parameters requiring datasheet validation and avoids inventing unavailable electrical or mechanical details.

Architecturally, the Arria II GX family combines 8-input fracturable ALMs, M9K memory blocks, MLAB distributed RAM, and dedicated variable-precision DSP blocks. Hard IP for PCIe Gen2, 10/100/1000 Ethernet MACs, and external memory controllers reduces soft-logic utilization and simplifies timing closure. The 40 nm process balances static and dynamic power, and the 'I3' speed grade places timing performance between I4 and I5 within the Arria II family. Typical applications include high-speed serial protocol bridging (PCIe Gen2 endpoints, 1G/10G Ethernet MACs), video broadcast and processing pipelines, wireless baseband and digital IF, military radar signal processing, and industrial imaging.

The large 35x35 mm package mandates a high-performance PCB stack-up; thermal management relies on a heat spreader attached directly to the flip-chip lid rather than forced-air cooling alone. This page synthesizes distributor pricing snapshots, drop-in alternative FPGAs from the same Arria II GX family, and practical design notes not found in the manufacturer datasheet alone, giving procurement and engineering teams a single, decision-ready reference.
EP2AGX190FF35I3N - Arria II GX FPGA, 181K LE, 612 I/O, FCBGA-1152 | Intel
The Intel (Altera) EP2AGX190FF35I3N is a high-density Arria II GX Field-Programmable Gate Array (FPGA) fabricated on a 40 nm low-power process, delivering 181,165 logic elements, 7,612 Logic Array Blocks (LABs), and up to 612 user I/O pins in a 1152-ball FineLine Ball-Grid Array (FC-FBGA / FCBGA) package. Operating at a core voltage of 0.9 V with embedded transceivers up to 500 MHz, the device combines high logic density with on-chip serial transceivers targeting cost-sensitive mid-range applications. What is an FPGA? A Field-Programmable Gate Array is a programmable logic device that engineers configure after manufacturing using a hardware description language (HDL) such as Verilog or VHDL. FPGAs occupy the middle ground between fixed-function ASICs (high NRE cost, high volume) and microcontrollers (software-defined, lower throughput). The Arria II GX family sits in the "mid-range transceiver-equipped" tier of the Altera/Intel portfolio, between Cyclone (low-cost) and Stratix (high-performance), and is commonly used when a design needs integrated multi-gigabit transceivers without paying for full Stratix-class fabric. Key features include integrated PCI Express Gen1/Gen2 hard IP blocks, up to 8.6 Gbps transceivers, dedicated DSP blocks for high-speed arithmetic, and on-chip memory with 9 Kbit M20K blocks. The device also provides hard memory controllers for DDR3 SDRAM and high-speed serial connectivity. Programmable logic resources reach 181,165 logic elements (LEs), supported by 1,036,800 bits of dedicated RAM. Arria II GX architecture combines an 8-lane adaptive logic module (ALM) per LAB with rich DSP and memory resources, allowing efficient implementation of DSP pipelines and parallel processing. The 40 nm process provides a favorable logic-to-power ratio compared with the 65 nm Stratix IV generation, making the part attractive for power-constrained applications where transceiver throughput remains critical. Typical applications include wireless baseband processing, broadcast video infrastructure, military radar and signal intelligence, medical imaging equipment, and high-speed serial protocol bridging. The combination of mid-range logic density and integrated transceivers makes it a common choice for PCI Express endpoint designs and proprietary backplane interfaces. Designers should plan for an industrial temperature grade (-40 °C to +100 °C junction) and ensure a robust decoupling network on the 0.9 V core and 1.1 V/2.5 V/3.3 V auxiliary rails. Use the Quartus II design suite (latest service pack for Arria II GX) for synthesis, place-and-route, and timing closure; bitstream encryption and remote update via the dedicated configuration block are recommended for production.

EP2AGX190FF35I5 - Arria II GX FPGA, 181165 LE, 612 I/O | Intel
The Intel (formerly Altera) EP2AGX190FF35I5 is a high-density Arria II GX Field-Programmable Gate Array fabricated on a 40 nm process, integrating 181165 logic elements, 10177536 bits of embedded memory, and 612 user I/Os in a 1152-ball flip-chip BGA (FC-FBGA) package. Built around the Arria II GX transceiver architecture, the device combines a rich general-purpose FPGA fabric with multi-gigabit transceivers, making it a drop-in fit for high-throughput serial-interface designs. An FPGA (Field-Programmable Gate Array) is a class of programmable logic device that lets designers configure arbitrary digital circuits through SRAM-based configuration memory. Within the broader semiconductor taxonomy, FPGAs sit alongside ASICs and CPLDs as the main forms of hardware-level programmable logic; Arria II GX is positioned as Intel's mid-range, transceiver-rich family that bridges between Cyclone V (low-cost) and Stratix IV (high-performance) families, aimed at cost-sensitive applications that still require multi-gigabit serial links. Key features of the EP2AGX190FF35I5 include integrated transceivers supporting multi-gigabit serial protocols, hard PCIe Gen1/Gen2 IP blocks, embedded memory blocks totaling 10.18 Mbits, dedicated DSP blocks for high-throughput signal processing, and a large user-I/O count (612) which supports wide parallel interfaces to external memories such as DDR2/DDR3 SDRAM, QDRII+ SRAM, and RLDRAM II. The industrial-grade speed-grade 5 designation means timing closure is rated for -40 C to +100 C ambient operation, which is suitable for telecom, industrial imaging, and military/aerospace subsystems. The 40 nm process node provides a useful balance between static and dynamic power consumption; the -I5 speed grade is the slowest in the Arria II GX family, trading peak Fmax for lower quiescent power and improved timing margin. The 1152-ball FC-FBGA package uses flip-chip BGA technology with a land-grid pitch suited to high-density PCB designs that require multiple signal layers and a continuous ground/power plane beneath the device. Typical applications for the EP2AGX190FF35I5 include wireless baseband processing, high-definition video broadcast equipment, medical imaging pipelines, military radar and signal-intelligence front-ends, and PCIe Gen2 host-bus adapter cards. Designers typically pair the part with external DDR3 SODIMMs, Flash configuration memories (EPCS), and clock-generation PLLs to form a complete embedded signal-processing subsystem. When designing with this FPGA, plan PCB stack-up carefully: 1152 balls at fine pitch demand microvia technology, a 1 oz copper power plane, and matched-length trace tuning for the transceiver channels. Use Intel Quartus II as the design entry, synthesis, place-and-route, and timing-analysis tool; Quartus II is mandatory for transceiver IP configuration and pin planning on Arria II GX devices. This page synthesizes distributor pricing snapshots, same-package alternatives, and practical Quartus II design-flow notes that go beyond the device datasheet, helping procurement and FPGA engineers make informed sourcing and substitution decisions.
