The APEX II architecture combines a LUT-based logic fabric with dedicated carry chains, hardware multipliers, and dual-port RAM blocks, allowing system-on-chip integration that would otherwise require multiple discrete components. Designers use VHDL or Verilog with the Quartus II design suite (versions 2.x through 5.x supported the APEX II family) to implement synthesis, place-and-route, and bitstream generation. Typical applications include telecommunications baseband processing, multi-channel DSP filtering, image and video preprocessing pipelines, ASIC prototyping, and high-speed serial protocol bridging where flexible I/O standards and parallel datapath performance matter most. Designers should plan for a 1.8V/3.3V multi-rail power architecture and ensure thermal vias beneath the FineLine BGA thermal pad; a -6 speed grade typically corresponds to roughly 50% higher Fmax than the slowest -7 grade and is often the volume-production choice.

FPGAs sit above CPLDs in the programmable logic taxonomy and below fixed-function ASICs in per-unit cost, occupying the sweet spot where high logic density, parallel processing, and reconfigurability are required. Within Intel's portfolio, the Arria II GX family targets mid-range applications that need integrated transceivers, embedded transceivers, and PCI Express hard IP without migrating to the higher-cost Stratix series. Key features of the EP2AGX125EF29C6G include up to 8.315 Mbits of embedded SRAM, embedded 18x18 multipliers for DSP, up to 8 high-speed transceivers per device family, hard PCI Express Gen1/Gen2 controllers, and a comprehensive clock management network with PLLs. The device supports JTAG (IEEE 1149.1) and passive/active configuration schemes including fast passive parallel (FPP) and active serial (AS). The 780-BGA package exposes 372 user I/O and provides the signal integrity needed for DDR2/DDR3 external memory interfaces running up to 533 MHz. The Arria II GX architecture uses adaptive logic modules (ALMs) rather than legacy 4-input LUTs, delivering finer-grained packing efficiency. The transceiver blocks support data rates up to 6.375 Gbps, enabling protocols such as PCIe Gen2, Serial RapidIO, and CPRI. The on-chip PLLs (up to 8 per device) support fractional-N synthesis, simplifying multi-frequency clock trees common in wireless baseband and video broadcast infrastructure. Typical applications include wireless baseband processing, video broadcast and contribution encoders, high-speed test and measurement backplanes, military signal processing cards, and PCI Express Gen2 endpoint/root-port designs. 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.

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 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.

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.

When designing with this device, allocate sufficient PCB layers (at least eight) and proper BGA fanout for the 780-ball FCBGA. Plan power-rail decoupling per the Altera Early Power Estimator (EPE) tool before schematic capture. This page synthesizes distributor stock, drop-in alternatives from the same Intel/Altera Arria II family, and practical design notes that complement the manufacturer datasheet.

Background: An FPGA (Field-Programmable Gate Array) is a programmable logic device that allows designers to implement custom digital circuits after manufacturing. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs) -> logic ICs -> integrated circuits -> semiconductors. Arria II GX family FPGAs specifically target mid-range applications requiring transceiver-based serial connectivity, such as broadband, wireless infrastructure, and broadcast equipment. Key features include 372 user I/O pins, on-die termination (OCT), and a wide operating temperature range suited for industrial environments. The 'C5G' suffix denotes commercial temperature grade with -5 speed grade silicon. The device supports multiple I/O standards including LVDS, LVTTL, LVCMOS, and high-speed serial protocols. Technical depth: The Arria II GX architecture employs adaptive logic modules (ALMs) instead of traditional 4-input LUTs, providing improved logic utilization. Hard memory controllers and DSP blocks accelerate common operations while reducing soft logic overhead. The transceiver blocks support multiple protocols including PCIe Gen2 x1/x4, XAUI, CEI-6.0, and Serial RapidIO. Typical applications include wireless baseband processing, HD-SDI video processing, high-speed data acquisition, and PCIe Gen2 endpoint cards. When designing with this device, ensure proper power sequencing for the 0.9V, 1.1V, 1.5V, 2.5V, and 3.3V rails and adequate thermal dissipation via the exposed die.

EP2AGX190EF29C6G - Arria II GX FPGA 190K LE, 780-FCBGA | Intel
The Intel (formerly Altera) EP2AGX190EF29C6G is a high-density Arria II GX Field Programmable Gate Array (FPGA) with 190,000 logic elements, 10,177,536 RAM bits (12,144 Kbit), 181,165 adaptive logic modules (ALMs), and a 780-ball Flip-Chip BGA (FCBGA) package rated for the -6 commercial speed grade. It targets mid-range, transceiver-rich applications requiring high logic density, embedded memory, and multi-gigabit serial I/O. An FPGA (Field Programmable Gate Array) is a programmable logic device that combines configurable logic blocks, programmable interconnect, and dedicated hardware blocks (transceivers, DSP slices, embedded RAM, PLLs) on a single die. FPGAs sit between generic microcontrollers and fixed-function ASICs in the silicon hierarchy: programmable logic -> configurable logic -> semiconductor. Arria II GX specifically bridges Cyclone (low-cost) and Stratix (high-performance) families by offering transceivers up to 6.375 Gbps with a balanced logic-and-transceiver fabric. Key features include 372 maximum user I/O pins, integrated PCI Express hard IP, multiple high-speed transceivers supporting 600 Mbps to 6.375 Gbps data rates, 8-input fracturable ALMs, dedicated DSP blocks, and on-chip PLLs for clock management. The device is built on a 40 nm process and supports 1.0 V, 1.1 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V single-ended I/O standards via bank-based configuration. The Arria II GX architecture separates logic resources (ALMs, M9K/M144K memory blocks, MLABs) from transceiver resources, allowing the same device to address protocols such as PCIe Gen1/Gen2, CPRI/OBSAI, Serial RapidIO, XAUI, and SGMII without external PHY chips. Hard IP blocks reduce soft-logic overhead and deterministic latency, critical for protocol bridging in wireless baseband and broadcast video. Typical applications include wireless base-station digital front-end, broadcast video processing and switching, PCIe Gen2 add-in cards, communications infrastructure line cards, and high-speed serial protocol bridging. The -6 commercial speed grade targets designs operating in 0C to 85C ambient with default speed margin. When designing with EP2AGX190EF29C6G, ensure power-rail sequencing follows Altera's POR guidelines and that transceiver reference clocks meet the +/-100 ppm jitter spec. Quartus II design software (13.0 and later service packs) is the required development environment.
