EP2S130F1508I4N - Stratix II FPGA, 132K LE, 1508-FBGA | Intel

The Intel (formerly Altera) EP2S130F1508I4N is a high-density Stratix II family Field-Programmable Gate Array (FPGA) delivering 132,540 logic elements, 6,747,840 bits of embedded RAM, and 1126 user I/Os in a 1508-ball FCBGA measuring 40 x 40 mm with a 1.0 mm ball pitch. Built on a 90 nm CMOS process with 1.2 V core supply, the device integrates 6,627 Logic Array Blocks (LABs) and supports up to 717 MHz internal operation across the industrial temperature range (-40C to +100C). An FPGA (Field-Programmable Gate Array) is a reconfigurable semiconductor containing an array of configurable logic blocks (CLBs/LABs), programmable routing, and dedicated hard-IP blocks such as memory, DSP, and high-speed transceivers. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs), which in turn belong to logic ICs and ultimately the integrated circuits (semiconductors) hierarchy. Stratix II devices specifically target high-performance digital signal processing, telecom, and ASIC-prototyping workloads where the combination of high logic density, abundant embedded memory, and a generous user-I/O count is essential. Key features of the EP2S130F1508I4N include 12 on-chip PLLs for clock synthesis and skew management, dedicated 18-bit x 18-bit hardware multipliers arranged as DSP blocks, support for multiple I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and HSTL, and a hard Nios II embedded processor soft-core option. The 1508-FCBGA package provides a large thermal pad for low thermal resistance, while the 1126 user I/Os offer ample connectivity for parallel memory buses, high-speed serial links via serializer/deserializer (SERDES) on companion Stratix II GX devices, and external PHY interfaces. Architecturally, the Stratix II family introduced the Adaptive Logic Module (ALM) - an 8-input fracturable LUT that delivers approximately 40 percent higher performance and 25 percent lower logic area than previous generations. Combined with the TriMatrix embedded memory architecture (three distinct RAM block sizes), this makes the EP2S130 the highest-density Stratix II variant, suitable for prototyping mid-to-large ASIC designs, high-end DSP pipelines, multi-channel telecom baseband processing, and high-throughput data acquisition systems. Typical applications include ASIC prototyping, multi-channel telecom infrastructure (SDH/SONET, OTN), high-speed data acquisition, software-defined radio (SDR) baseband processing, and high-end video/image processing systems. Designers choose this part when maximum logic density and embedded memory in a single device outweigh the need for the latest transceivers. When designing with the EP2S130F1508I4N, ensure a 4-layer or better PCB with continuous power planes and adequate decoupling on the 1.2 V VCCINT and 3.3 V VCCIO rails - the device draws significant inrush current during configuration. Industrial-grade temperature (the I4 suffix) is verified for -40C to +100C ambient operation. This page synthesizes distributor pricing, drop-in alternatives, design notes, and parametric comparisons that complement the Intel Stratix II Device Handbook, helping engineers source, qualify, and select the right Stratix II variant for production and prototype builds.

EP2S130F1508I4RB - Stratix II FPGA, 132K LEs, 1508-FCBGA | Intel

The Intel EP2S130F1508I4RB is a high-density Stratix II family Field-Programmable Gate Array (FPGA) integrating 132,540 logic elements, 6,747,840 bits of embedded memory, and 1,126 user I/O pins in a 1508-ball FineLine BGA (FCBGA) package, targeted at high-performance logic, DSP, and memory-intensive designs. The device is the industrial temperature grade variant and ships on tape-and-reel (suffix RB), making it production-line-ready for high-volume assembly. The Stratix II family is built on a 90 nm process and uses an adaptive logic module (ALM) architecture that delivers up to 50 percent higher performance and 40 percent lower power than the prior Stratix generation. An FPGA is a programmable logic device that engineers configure after manufacturing to implement arbitrary digital circuits, replacing fixed-function ASICs while providing faster time-to-market, in-system re-programmability, and integrated hard IP blocks such as transceivers, memory controllers, and DSP blocks. The Stratix II sits in the high-end of the Altera/Intel FPGA portfolio, between the Cyclone II cost-optimized family and the Stratix III mid-range, and is commonly used in telecom line cards, military signal processing, and ASIC prototyping. Key features include 132,540 equivalent logic elements (LEs), 6,747,840 embedded RAM bits organized in M512/M4K/M-RAM blocks, 1,126 user I/O pins with support for multiple I/O standards (LVDS, LVTTL, LVCMOS, SSTL, HSTL, PCI, PCI-X), 12 dedicated clock pins, up to 1 Gbps LVDS performance, and embedded multiplier blocks for DSP. The 1508-FCBGA package uses Intel's flip-chip BGA technology for low-inductance power distribution and high pin count at modest board area (40 mm x 40 mm typ.). The Stratix II architecture introduces the ALM (8-input fracturable look-up table) which can be split into two independent 4-input LUTs, increasing effective logic utilization versus older 4-input LUT architectures. Each ALM also contains two dedicated adders and registers, enabling high-speed arithmetic paths without consuming general routing. TriMatrix memory provides three block sizes (M512, M4K, M-RAM) so that small FIFOs and large buffers share the same fabric with predictable timing. Typical applications include high-speed digital signal processing, ASIC prototyping, telecom line-card packet processing, military radar and signal intelligence, broadcast video processing, and high-throughput data-acquisition front-ends. The device is well matched to designs that need hundreds of DSP multipliers and megabits of on-chip buffering on a single die. When designing the PCB, allocate a continuous GND reference under the BGA, use at least 8 PCB layers with dedicated VCCINT/VCCIO planes, and decouple every 6-10 balls with 100 nF X7R capacitors plus bulk tantalum or polymer capacitors near the package. Configuration can be loaded via fast passive parallel (FPP), passive serial (PS), or JTAG, and the EP2S130 supports remote upgrade through the dedicated AS/PS configuration flash port.

EP2S130F780C4

EP2S130F780C4 - Stratix II FPGA 132K LE 534 I/O FBGA | Intel / Altera

The Intel / Altera EP2S130F780C4 is a high-density Stratix II family field-programmable gate array (FPGA) housed in a 780-ball fine-pitch BGA (FC-FBGA) package measuring 40 x 40 mm with 1 mm ball pitch. The device integrates approximately 132,540 logic elements across 6,627 logic array blocks (LABs) and exposes 534 user I/O pins, with internal performance hardened to 717 MHz and built on a 90 nm CMOS process with a 1.2 V core supply. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs), programmable interconnect, and dedicated hard-IP blocks such as block RAM, DSP multipliers, PLLs, and high-speed transceivers. FPGAs occupy the highest tier of the programmable logic hierarchy, above CPLDs (smaller, non-volatile, simpler architecture) and below ASICs (custom-fabricated, lowest per-unit cost at scale). Within Altera's Stratix product tree, the Stratix II family specifically targets high-end DSP, telecom, and high-throughput data-pipeline applications using an adaptive logic module (ALM) architecture that delivers higher effective logic density than previous-generation 4-input LUT designs. The EP2S130F780C4's headline feature is its very large embedded memory and DSP multiplier count, which together enable designers to implement wide, parallel data paths without external memory. The device also integrates dedicated high-speed serial interfaces suited to backplane and chip-to-chip links, and its 780-pin FC-FBGA package provides sufficient I/O for parallel memory buses and multiple standard interfaces. The 'C4' speed grade and 'F' package code designate the commercial temperature range and the flip-chip BGA pinout, respectively. Typical applications include high-speed digital signal processing (radar, software-defined radio, video transcoding), ASIC prototyping, telecom line-card glue logic, high-throughput data acquisition, and embedded computing platforms that require parallel compute resources. Designers usually pair the device with external DDR/DDR2 memory and dedicated PHY companions to exploit its on-chip memory bandwidth. When designing with this FPGA, plan power-rail sequencing carefully - the 1.2 V core typically requires a multi-phase buck regulator, while the I/O and auxiliary supplies need separate rails. Thermal management is critical at full utilization: ensure adequate airflow or a heatsink attached to the 40 x 40 mm substrate, since FC-FBGA packages rely primarily on the PCB for heat dissipation.

An FPGA (Field-Programmable Gate Array) is a programmable logic device belonging to the wider semiconductor hierarchy of programmable logic -> logic IC -> integrated circuit. FPGAs sit between fixed-function ASICs and software-driven processors: they implement arbitrary digital logic in configurable look-up tables (LUTs), programmable interconnect, and dedicated hard IP such as block RAM, PLLs, transceivers, and DSP blocks, allowing rapid design iteration without the mask costs of an ASIC. Key features of the EP2S130F780C4N include up to 717 MHz internal clock frequency, embedded TriMatrix memory supporting dual-port and FIFO modes, up to 12 dedicated PLL blocks for clock synthesis and management, and support for external memory interfaces such as DDR, DDR2, QDR, and RLDRAM. The device supports multiple I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and HSTL through dedicated I/O buffers with on-chip termination. Architecturally, the Stratix II family introduced an innovative adaptive logic module (ALM) topology that gives roughly 40% higher performance per area than the prior Stratix architecture, and the EP2S130F780C4N integrates up to 16 global clock networks plus regional clock trees. The 780-pin FC-FBGA package uses a 1 mm pitch on a 29x29 mm substrate, enabling dense PCB routing while supporting industrial temperature grades through ordering options. Typical applications include high-speed digital signal processing in radar and software-defined radio, ASIC prototyping, video processing and broadcast equipment, telecom line cards, industrial control and machine vision, and PCIe-based accelerator cards. The wide DSP block count and ample on-chip memory allow designers to push large FFT/fir pipelines at hundreds of MSPS without external memory round-trips. When designing with this device, careful attention must be paid to power integrity because Stratix II devices can exceed 25 W dynamic power under heavy utilization. Designers must follow Intel/Altera's power-supply decoupling guidance with bulk, mid-frequency, and high-frequency capacitors placed close to the dedicated VCCINT, VCCIO, and GND balls, and a multi-layer PCB stackup with dedicated power/ground planes is required for signal integrity at LVDS and DDR2 rates. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that go beyond what is found in the manufacturer datasheet, providing engineers with a single reference for sourcing, replacement planning, and PCB-level design considerations.

Architecture: The Stratix II family uses an adaptive logic module (ALM) architecture that combines 8 inputs into a single lookup-table-equivalent resource, providing roughly 25% higher logic utilization versus traditional 4-input LUT families. The TriMatrix memory subsystem provides three block RAM sizes (M512, M4K, M-RAM) for flexible buffering, and the embedded DSP blocks deliver 36 x 36 bit multiplication natively, supporting signal-processing pipelines at hundreds of MHz. Typical applications include high-performance digital signal processing in telecommunications base stations, ASIC prototyping, industrial vision and image processing pipelines, broadband network switches, and test and measurement equipment. The 780-FBGA package and 534 I/Os make it well suited for designs requiring wide external memory buses (DDR/DDR2) and many parallel interfaces. Design considerations: Stratix II devices require two supply rails (1.15-1.25 V core, 3.3 V I/O) and careful decoupling with 0.1 µF and 0.01 µF ceramic capacitors near every power pin. The 780-FBGA 29 x 29 mm package uses a 1 mm ball pitch and demands a 4-to-6-layer PCB with microvia or via-in-pad technology for reliable manufacturing; signal integrity analysis is mandatory for DDR interfaces.

Architecturally, Stratix II introduced the TriMatrix memory hierarchy with three block RAM sizes (M512, M4K, M-RAM) and a row-based architecture that places memory and DSP columns adjacent to the logic array. This provides predictable timing for high-throughput data paths in applications such as wireless baseband, video processing, and high-speed serial interfaces. The 90 nm process node combined with a 1.2 V core voltage gives the device a balance of performance and power efficiency for mid-density designs. Typical applications include telecommunications infrastructure, software-defined radio, high-speed imaging and video pipelines, ASIC prototyping, and industrial control. The device is also frequently used in test and measurement equipment where its DSP blocks and large memory are well matched to real-time signal processing. When designing with this FPGA, engineers must supply multiple voltage rails (core, PLL, I/O banks) and observe strict PCB layout requirements for the FBGA substrate, including microvia or via-in-pad construction to break out the 1.0 mm pitch BGA. Quartus II is the canonical design toolchain for programming and configuring this device family.

The C3 speed grade and industrial temperature profile make it a workhorse for medium-density, high-throughput digital designs that need embedded DSP and TriMatrix memory. A field programmable gate array (FPGA) is a semiconductor device whose logic fabric, interconnect, and I/O cells are configured after manufacture via a configuration bitstream, allowing the same silicon to implement almost any digital function from glue logic to fully featured processors. Within the broader taxonomy, the EP2S15 sits as an FPGA under programmable logic, which sits under digital logic ICs, which sit under integrated circuits. Stratix II was Intel's second-generation high-end FPGA, succeeding Stratix I with a refined 90 nm logic architecture and adaptive look-up tables (ALUTs) that improved performance per LE relative to its predecessor. Key features include 15,600 logic elements, 419,328 RAM bits organized into TriMatrix memory blocks, dedicated DSP blocks for high-speed multiply-accumulate operations, up to 12 PLLs for clock management, and support for external memory interfaces including DDR, DDR2, SDRAM, QDR, and RLDRAM. The device exposes 342 user I/Os across multiple I/O banks supporting LVDS, LVTTL, LVCMOS, SSTL, HSTL, and PCI/PCI-X signaling. Configurable logic capacity is complemented by 15600 equivalent LEs, an internal configuration scheme, JTAG boundary scan, and active serial/parallel configuration modes. Typical applications include telecom line cards, high-speed serial protocol bridging (SPI 4.2, SFI, UTOPIA), DSP co-processing for radar and imaging, broadcast video processing, and PCI/PCI-X bus expansion. The combination of embedded multipliers and TriMatrix memory also suits software-defined radio front-end datapaths and ASIC prototyping. When designing with the EP2S15F484C3N, pay attention to power integrity on the 484-ball BGA - the Stratix II datasheet recommends a multi-layer PCB with dedicated power and ground planes and at least six PCB layers for signal integrity at DDR2 rates. Decoupling must follow Intel's reference decoupling network. Configuration scheme selection (AS, PS, JTAG, or Fast Passive Parallel) must be planned early because it affects pin allocation.

The Altera (Intel) EP2S15F484I4 is a Stratix II family Field Programmable Gate Array (FPGA) with 15,600 logic elements, 419,328 bits of embedded RAM, and 342 user I/Os, housed in a 484-ball FineLine BGA (FBGA) package at industrial temperature grade (-40C to +100C). Built on a 90 nm process node with a 1.2 V core supply, it integrates up to 12 transceiver blocks and dedicated DSP blocks for high-throughput signal processing in a single device. The 484-pin FBGA package provides high I/O density for memory-rich and transceiver-heavy designs. A Field Programmable Gate Array (FPGA) is a type of programmable logic device that lets engineers configure digital logic, memory blocks, and I/O after manufacturing. Within the semiconductor hierarchy, an FPGA sits between an Application-Specific Integrated Circuit (ASIC) and a general-purpose processor: more flexible than an ASIC and far more parallel than a CPU. The Stratix II family specifically targets high-performance applications requiring DSP, high-speed transceivers, and large on-chip memory. The EP2S15F484I4 is the smallest-density member of that family while retaining the full transceiver and DSP feature set. Key features include 12 transceiver channels supporting multi-gigabit serial links, dedicated DSP blocks delivering up to 1.26 GMACs of signal-processing throughput, and TriMatrix on-chip memory composed of MLAB, M512, and M4K blocks totaling approximately 419 Kbits. Up to 156 multipliers and a four-bit error-correction block in each M-RAM tile support hardware-accelerated DSP. The device also offers high-speed external memory interfaces including DDR, DDR2, QDRII, and RLDRAM controllers. Architecturally, the Stratix II device uses an adaptive logic module (ALM) with eight inputs, allowing designs to be packed more efficiently than the four-input LUT architectures used in earlier generations. Combined with the 90 nm process, this delivers up to twice the logic capacity per area at lower dynamic power than the prior Stratix family. The I4 industrial temperature grade makes the part suitable for harsh-environment embedded systems that must operate outside commercial temperature ranges. Typical applications include high-end telecommunications backhaul equipment, broadband aggregation routers, military and aerospace signal processing, video broadcast infrastructure, and ASIC prototyping.

Designers can implement PCI Express, Gigabit Ethernet, DDR memory controllers, and custom DSP pipelines using the embedded transceivers, multipliers, and I/O resources. When designing with this device, attention must be paid to BGA fan-out and routing density, as well as power plane design for the multiple internal voltage rails (core, I/O, PLL auxiliary). The 672-ball FineLine BGA package requires multi-layer PCB fabrication with via-in-pad or dog-bone fanout patterns to escape all signals without requiring additional PCB area.

It is specified at -40C to +85C industrial temperature range and features a 1.2V core supply for low-power, high-density programmable logic. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that engineers can configure after manufacturing. FPGAs sit between custom ASICs and fixed-function ICs in the design hierarchy: PLD -> CPLD -> FPGA -> ASIC, and are widely used for digital signal processing, glue logic, high-speed interfacing, and prototyping. The Stratix II family specifically targets high-performance applications with embedded multipliers, DSP blocks, and high-speed transceivers. Key features include 15,600 logic elements (LEs), 419,328 RAM bits (approximately 52 KB), 156 embedded multipliers, dedicated DSP blocks, and support for external memory interfaces including DDR/DDR2 SDRAM and QDRII SRAM. The 672-BGA package provides high I/O density for complex system designs requiring many parallel interfaces. The EP2S15F672C4N is fabricated in a 90 nm CMOS process with a 1.2V core voltage, and supports configuration via JTAG, passive serial, or active serial modes. The architecture is built around the Adaptive Logic Module (ALM), which improves logic utilization efficiency compared to traditional 4-input LUT architectures. Typical applications include high-speed digital signal processing, telecommunications infrastructure, video and image processing, military/aerospace systems, ASIC prototyping, and high-bandwidth data acquisition. The high logic density and embedded multipliers make it particularly suited for DSP-intensive designs such as FFT engines and video codecs. When designing with this part, pay careful attention to power sequencing: the 1.2V core supply must ramp before I/O voltages to avoid latch-up. Use the Quartus II design software (legacy) or the modern Intel Quartus Prime with Stratix II device support for synthesis, place-and-route, and bitstream generation. This page synthesizes distributor pricing across 16+ sources, parametric drop-in alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers evaluate this legacy Stratix II part for new designs or long-term support scenarios.

EP2S15F672I4 - 15K LEs Stratix II FPGA 672-FBGA | Intel / Altera
EP2S15F672I4

EP2S15F672I4 - 15K LEs Stratix II FPGA 672-FBGA | Intel / Altera

The Intel (formerly Altera) EP2S15F672I4 is a Stratix II family Field Programmable Gate Array (FPGA) with 15,600 logic elements, 419,328 bits of embedded memory, 156 embedded 18x18 multipliers, and 366 user I/Os, housed in a 672-ball FineLine BGA (FBGA) package with industrial temperature grade (-40C to +100C). It is fabricated on a 90 nm process and targets high-performance digital signal processing, telecommunications, and embedded compute applications. A Field-Programmable Gate Array (FPGA) is a programmable logic device consisting of an array of configurable logic blocks (LABs), embedded memory, DSP blocks, and programmable interconnect. FPGAs belong to the broader hierarchy of programmable logic devices -> ASIC prototyping platforms -> digital semiconductor ICs. Stratix II FPGAs sit in the high-performance tier of the Altera/Intel portfolio, integrating hard DSP blocks, transceivers, and large on-chip RAM for compute-intensive designs. Key features of the EP2S15F672I4 include up to 6.3 Gbps embedded transceivers on certain Stratix II variants, dedicated 18x18 multipliers totaling 156 DSP blocks, TriMatrix embedded memory architecture supporting true dual-port and FIFO operation, and support for external DDR/DDR2/QDR memory interfaces via dedicated PHY blocks. The device supports configuration via passive serial (PS), fast passive parallel (FPP), and JTAG, with built-in error detection/correction on configuration RAM. The Stratix II architecture separates the routing switch into a heterogeneous multi-tier network with dedicated paths between LABs, M512/M4K/M-RAM blocks, and DSP blocks. This reduces critical-path delay and improves timing closure compared to earlier Stratix generations. The 672-FBGA package exposes 366 user I/Os, which is the maximum for this die size in the Stratix II family. Typical applications include high-throughput DSP pipelines (radar, beamforming, video codec acceleration), wire-speed packet processing in networking line cards, ASIC prototyping, military/aerospace signal processing, and industrial machine-vision controllers. The combination of 156 multipliers and 419 Kbits of block RAM enables high FIR/FFT throughput without external memory bottlenecks. Design consideration: Stratix II devices require a 1.2 V core supply plus multiple I/O bank supplies (1.5 V, 1.8 V, 2.5 V, 3.3 V selectable per bank). Power estimation should use the Quartus II PowerPlay Early Power Estimator before PCB layout, since the 672-FBGA has limited heat dissipation and high-density Stratix II designs typically require forced-air cooling or a thermal management plan. This page synthesizes real-time distributor pricing, drop-in same-package alternatives, and engineering design notes not found in the manufacturer datasheet alone, giving procurement and design engineers a single decision-ready reference for the part.
