EP2SGX130GF40I4GA - Stratix II GX FPGA, 132K LE, 1508-FCBGA | Intel

The Intel (formerly Altera) EP2SGX130GF40I4GA is a high-density Stratix II GX Field-Programmable Gate Array (FPGA) with 132,540 logic elements, 6,747,840 total memory bits, and integrated transceivers, housed in a 1508-ball flip-chip BGA (FCBGA) package at industrial temperature grade. It belongs to the Stratix II GX family, which combines a 90 nm logic fabric with up to 20 multi-gigabit transceivers operating from 600 Mbps to 6.375 Gbps, making it engineered for high-speed serial I/O applications such as backplane connectivity, broadband communications, and storage area networks. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) within the broader integrated circuit hierarchy (programmable logic -> semiconductor -> IC) that allows designers to configure hardware functionality after manufacturing. FPGAs sit between ASICs and general-purpose processors in the design flexibility/performance trade-off, offering hardware-timed parallelism, reconfigurability, and high-speed I/O without the NRE cost of an ASIC. The Stratix II GX family is positioned as a high-performance transceiver-enabled tier above the logic-only Stratix II family. Key features include 132,540 logic elements organized into 6,627 Logic Array Blocks (LABs), 734 dedicated input pins and 734 dedicated output pins, 6.7 Mbits of embedded RAM, embedded DSP blocks, and 1.00 mm ball pitch for the FCBGA-1508 package. The device integrates up to 20 transceivers that support PCI Express, Serial RapidIO, XAUI, and other high-speed serial standards. Industrial temperature grade (-40C to +100C ambient) supports deployment in harsh environments beyond commercial-grade parts. Architecturally, the Stratix II GX uses Altera's adaptive logic module (ALM) architecture, which replaces the traditional 4-input LUT with an 8-input fracturable LUT, yielding higher logic utilization and faster clocking networks. Multi-gigabit transceivers feature clock-data recovery, transmit pre-emphasis, and receive equalization to maintain signal integrity over backplane and cable channels at multi-gigabit data rates. Typical applications include high-end telecommunications line cards, broadcast video routers, military radar signal processing, ASIC prototyping, and PCI Express endpoint cards. The integrated transceivers also suit Fibre Channel switches, Serial RapidIO bridges, and 10 Gigabit Ethernet MAC implementations in networking line cards. When designing with this device, ensure the PCB has matched-length differential routing for the transceiver channels and a solid reference plane under the BGA footprint for power delivery. Plan FPGA configuration carefully - the device requires a configuration device or JTAG chain for in-system programming, and thermal management at industrial temperatures is critical given the FCBGA package's thermal resistance.

The Altera EP2SGX300DF780C5N is a high-density, high-performance Stratix II GX FPGA delivering 300,000 equivalent logic elements (LEs), 18,210 Kbits of embedded memory, and 20 multi-gigabit transceivers in a 780-pin FineLine BGA package, fabricated on a 90 nm process with 1.2 V core voltage. What is an FPGA? A Field-Programmable Gate Array (FPGA) is a semiconductor device built around a matrix of configurable logic blocks (CLBs) connected via programmable interconnect. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs) -> complex programmable logic devices (CPLDs) -> FPGAs -> high-speed transceivers integrated FPGAs. Stratix II GX FPGAs target high-bandwidth serial I/O applications where the device must both process logic and move data at multi-gigabit rates, making them a member of the broader power management and digital signal processing ecosystem. Key features include 20 full-duplex transceivers supporting data rates from 600 Mbps to 6.375 Gbps, 384 dedicated 18x18 multipliers for DSP, 8 PLLs, and 12 global clock networks. The device integrates 16 channels of on-chip SERDES termination, PCI Express hard IP, and supports multiple serial protocols including PCI Express, Serial RapidIO, XAUI, CEI-6G, and Gigabit Ethernet. The EP2SGX300DF780C5N is built on Altera's adaptive logic module (ALM) architecture, replacing the older 4-input LUT structure with 8-input fracturable ALMs. This architecture delivers up to 2x performance per logic element compared to prior generations while reducing compile times. The transceiver blocks each contain dedicated physical coding sublayer (PCS) and physical medium attachment (PMA) circuitry, supporting both AC and DC coupling. Typical applications include high-end telecommunications equipment, 10 Gbps data aggregation switches, base station channel cards, broadcast video processing systems, and high-performance computing accelerators. The device's hard PCI Express endpoint and root complex support make it ideal for high-bandwidth adapter cards and backplane designs. When designing with this FPGA, power estimation should be performed early using the Altera PowerPlay early power estimator, as the 6.375 Gbps transceivers can dominate total power consumption. Designers should also pay attention to PCB layer stackup to maintain signal integrity for the 6.375 Gbps serial links; recommended stackups are documented in the Stratix II GX Device Handbook, Volume 2. This page synthesizes real-time distributor pricing, drop-in Altera Stratix II GX and Stratix IV GX alternatives in the same FineLine BGA-780 package, and practical design notes not consolidated in the manufacturer datasheet — a resource for BOM consolidation and supply-chain risk reduction.

EP2SGX30CF780C3

EP2SGX30CF780C3 - Stratix II GX FPGA, 33.88K LE, 780-BGA | Intel

The Intel (Altera) EP2SGX30CF780C3 is a Stratix II GX family Field-Programmable Gate Array (FPGA) integrating 33,880 logic elements, 1,369,728 bits of embedded RAM, and 361 user I/Os in a 780-ball FineLine BGA package. It is fabricated on a 90 nm process and features 1,694 Logic Array Blocks (LABs), making it well suited for data-path-heavy designs that require both high logic density and substantial on-chip memory. A Field-Programmable Gate Array (FPGA) is a semiconductor device built from an array of configurable logic blocks (CLBs), programmable interconnects, and dedicated silicon resources such as block RAM, DSP slices, and high-speed transceivers. FPGAs sit between general-purpose microcontrollers and fixed-function ASICs in the design hierarchy: programmable logic IC -> FPGA -> SRAM-programmable FPGA -> high-density FPGA with transceivers. They allow hardware designers to implement custom parallel processing pipelines, custom I/O protocols, and glue logic without the NRE cost of an ASIC, which is why Stratix II GX parts are commonly used in prototyping and low-volume production. Key specifications of the EP2SGX30CF780C3 include up to 33,880 logic elements, 1,694 LABs, 1,369,728 RAM bits, 361 user I/Os, embedded 3.125 Gbps transceivers for serial connectivity, and support for DDR/DDR2/QDRII external memory interfaces via dedicated PHY. The 780-ball FineLine BGA package supports high I/O count while keeping the PCB footprint manageable for mid-complexity boards. Operating temperature is graded commercial (0C to +85C), and the speed grade is -3. The Stratix II GX architecture uses a logic-element fabric with adaptive look-up tables (ALUTs), a TriMatrix memory subsystem, and dedicated DSP blocks. The GX suffix indicates the integration of high-speed serial transceivers, which historically positioned this family for communication-infrastructure, broadcast video, and high-speed serial-protocol bridging applications. Designers should pay attention to Quartus II tool support, as Quartus versions for legacy Stratix II devices are mature but no longer under active development, and Intel recommends migrating to Stratix IV/V families for new designs. Typical applications include communication infrastructure (protocol bridges, backplane SERDES), broadcast video processing, industrial test and measurement, ASIC prototyping, and high-speed data acquisition. The combination of transceivers, block RAM, and abundant logic density makes the EP2SGX30CF780C3 suitable for custom packet-processing engines and for replacing discrete logic + memory glue in mid-complexity designs. When designing with this part, ensure your PCB layout supports the 1.0 mm or 1.27 mm pitch BGA fanout and that signal-integrity simulations are run on the transceiver channels. Because the Stratix II family is mature, plan firmware/quartus tool availability in your long-term roadmap. For new designs, also evaluate Stratix IV GX, Cyclone V GX, or Cyclone 10 GX as modern drop-in-compatible successors with active toolchain support.

EP2SGX30CF780C3N

EP2SGX30CF780C3N - Stratix II GX FPGA, 33880 Cells | Intel

The Intel EP2SGX30CF780C3N is a member of the Stratix II GX family of field-programmable gate arrays (FPGAs), featuring 33,880 logic cells, a 717 MHz maximum operating frequency, and integrated transceivers in a 780-pin FC-FBGA package. Built on a 90 nm CMOS process and supplied by a 1.2 V core rail, this device is engineered for high-bandwidth serial I/O, embedded processing, and digital signal processing (DSP) applications in communications infrastructure, video imaging, and storage systems. An FPGA (Field-Programmable Gate Array) is a semiconductor device whose logic fabric, interconnect, and I/O behavior are defined by a user-supplied configuration bitstream rather than by fixed mask layers. Within the broader taxonomy, FPGAs sit alongside microcontrollers, DSPs, and ASICs as programmable logic devices, and Stratix II GX represents Intel's mid-to-high density tier with built-in multi-gigabit transceivers, dedicated DSP blocks, and TriMatrix embedded memory. The 'GX' suffix denotes integrated serializer/deserializer (SERDES) channels, distinguishing this family from the non-transceiver Stratix II line. The 33,880 logic elements are organized into 33,880 CLBs (configurable logic blocks) backed by approximately 1.4 Mbits of embedded RAM distributed across TriMatrix memory structures, and the device integrates dedicated 18-bit x 18-bit multipliers for DSP operations. The integrated transceiver block supports multiple serial protocols, eliminating external PHY chips in many designs and reducing both board area and bill of materials cost. The 780-ball fine-pitch BGA package exposes roughly 600 user I/O pins, supporting LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards with on-chip termination. Configuration is supported via passive serial (PS), fast passive parallel (FPP), and JTAG modes, with optional configuration via EPC serial configuration devices. Designers using the Quartus II design software can target this device with either VHDL or Verilog HDL and benefit from the mature IP library that has shipped with the Quartus toolchain since the early 2000s. Typical applications include 3G/4G wireless baseband processing, high-speed serial backplane switching, broadcast video processing, and military radar signal chains. The combination of logic density and embedded transceivers makes the EP2SGX30CF780C3N particularly well-suited to line cards that aggregate multiple SFP/SFP+ or SERDES links while performing protocol bridging or packet classification. Compared with newer Cyclone V or Arria 10 FPGAs, the Stratix II GX family is fabricated on a 90 nm process and consumes noticeably more static power, so most new designs now favor the Stratix V or Stratix 10 families instead. When designing with the EP2SGX30CF780C3N, verify that the Quartus II version in use supports the device family (Quartus II 9.1 or earlier) and provide adequate thermal relief for the 780-ball FC-FBGA, since high transceiver utilization can push junction temperatures into the 100 C range without airflow.

The Stratix II GX family specifically targets applications requiring both general-purpose logic and multi-gigabit transceivers, positioning it as a power-management-aware programmable alternative to discrete PHY plus FPGA solutions. Key features of the EP2SGX30CF780C6 include up to 6.375 Gbps transceiver data rate, 1.4 Mbits of embedded RAM (TriMatrix), dedicated 18x18 multipliers, and built-in PCI Express hard IP. The device supports DDR/DDR2/QDRII memory interfaces with dedicated DQS circuitry, dynamic phase alignment for source-synchronous interfaces, and signalTap II embedded logic analysis for in-system debug. The F780 package offers 361 user I/Os arranged in 8 I/O banks, providing flexible I/O standard support including LVDS, SSTL, HSTL, and LVCMOS at multiple voltages. Architecturally, the Stratix II GX employs an adaptive logic module (ALM) with 8 inputs per ALM, replacing the 4-input LUT architecture used in earlier Stratix families. This allows tighter logic packing and improved performance on wide fan-in functions. The transceiver blocks embed clock-data recovery (CDR), 8B/10B encoding/decoding, and word-alignment logic, offloading these functions from the fabric and freeing logic resources for application-level processing. Typical applications include wireless baseband processing, high-end test and measurement equipment, broadcast video infrastructure, and PCI Express endpoint cards for industrial control or data acquisition. The 6.375 Gbps transceivers also make it suitable for proprietary chip-to-chip links and backplane serial connectivity in storage or telecom systems. When designing with this device, ensure that the Quartus II fitter pin assignments respect each bank voltage (1.2 V to 3.3 V) and that the transceiver reference clocks are routed with controlled impedance. Thermal management is critical in F780 BGA packages because the bottom-side balls carry both signal and thermal dissipation; refer to the manufacturer thermal model for junction-to-case resistance when calculating heatsink requirements.

EP2SGX30CF780C7 - Stratix II GX FPGA 33K LEs 780-BGA | Intel

The Intel (formerly Altera) EP2SGX30CF780C7 is a Stratix II GX family FPGA integrating 33,000 equivalent logic elements, 1.9 Mbits of embedded memory, and 4 full-duplex 3.125 Gbps multi-gigabit transceivers (MGTs) in a 780-pin flip-chip BGA package. Built on a 90nm process with 1.2V core operation, the device combines high-density programmable logic with embedded serial transceivers, making it a single-chip solution for high-speed serial I/O bridging, baseband processing, and protocol aggregation designs. What is a Stratix II GX FPGA? A Field-Programmable Gate Array (FPGA) is a semiconductor device containing configurable logic blocks (CLBs), programmable interconnects, and dedicated hard IP blocks that engineers can re-program after manufacture. The Stratix II GX family extends the Stratix II architecture with embedded multi-gigabit transceivers, positioning the device between pure logic FPGAs and structured ASSPs. Within the broader semiconductor taxonomy, the EP2SGX30CF780C7 belongs to: FPGA -> programmable logic -> digital ASIC alternative -> semiconductor IC. This hypernym chain is important for knowledge graph and AI-search entity matching. Key features include up to 4 transceivers operating from 600 Mbps to 3.125 Gbps, support for PCI Express x1/x4, Serial RapidIO, XAUI, Gigabit Ethernet, and SDI serial protocols without external PHY devices. The device also integrates 4 PLLs, 256 18x18 hardware multipliers (DSP blocks), and supports configuration via passive serial, fast passive parallel, passive parallel asynchronous, and JTAG modes. The CF780 package variant uses a wire-bond or flip-chip BGA with 780 balls on a 1.0 mm pitch. The Stratix II GX architecture uses Adaptive Logic Modules (ALMs) - each ALM contains two combined adaptive look-up tables (ALUTs) that can be partitioned into two independent 4-input LUTs or one 6-input LUT, providing finer-grained logic utilization than traditional 4-LUT FPGA architectures. The 90nm low-k dielectric process enables a 1.2V core voltage with sub-watt static power at room temperature, while I/O banks support 1.5V, 1.8V, 2.5V, and 3.3V standards. Typical applications include multi-gigabit serial backplane bridging, telecom framer/mapper ASIC replacement, military and aerospace signal processing, broadcast video routing, and PCI Express endpoint/root complex prototypes. The integrated transceivers are also well suited to test equipment where protocol-agnostic serial I/O is required. Designers in industrial imaging, medical imaging, and software-defined radio also benefit from the high DSP multiplier count combined with the serial bandwidth. A primary design consideration is power estimation: at 3.125 Gbps all 4 transceivers active, the EP2SGX30CF780C7 typically dissipates 3-5W from the transceiver supply and 0.5-1.5W from logic and clock resources, requiring a 6-8 layer PCB with dedicated power planes and 1oz copper on outer layers. The C7 speed grade provides faster Fmax than C6 but at higher static power. The C7N/C7 commercial temperature grade (0C to +85C) differs from I4/I5 industrial (-40C to +100C) variants.

The Intel / Altera EP2SGX30DF780C3N is a Stratix II GX Field-Programmable Gate Array (FPGA) IC integrating 33,880 logic elements (LEs), 1,369,728 bits of embedded memory, and 361 user I/Os in a 780-ball Fine-pitch Chip-Scale BGA (FC-FBGA, 29 x 29 mm, 1.0 mm pitch) package. Built on a 90 nm CMOS process with a 1.2 V core supply, the device belongs to the Stratix II GX family that combines a high-density logic fabric with up to 20 high-speed transceiver channels featuring embedded clock-data recovery (CRU) and SERDES at data rates up to 6.375 Gbps per channel. The device is qualified for industrial operating temperatures from -40 C to +85 C and supports JTAG boundary-scan configuration alongside in-system programmability. What is an FPGA with embedded transceivers? A Field-Programmable Gate Array is a programmable logic device that engineers configure after manufacturing, providing a flexible hardware platform that can implement any digital function up to its resource limits. When the fabric is augmented with multi-gigabit transceivers, the same silicon can drive high-speed serial links - backplane SerDes, fibre-channel, Serial RapidIO, PCIe, or custom chip-to-chip protocols - without external PHYs. The Stratix II GX family extends the general Stratix II architecture (logic array, TriMatrix memory, DSP blocks) with hardened PMA/PCS transceiver blocks and reference-clock PLL infrastructure, occupying a position above soft-logic-only FPGAs but below ASSPs in the programmable logic hierarchy (FPGA -> programmable logic -> logic IC -> integrated circuit -> semiconductor). Key differentiating features of the EP2SGX30DF780C3N include 6.375 Gbps per-channel transceiver support, TriMatrix embedded SRAM blocks for flexible FIFO and buffer construction, dedicated DSP blocks for high-throughput multiplication and accumulation, and a 1.0 mm-pitch FC-FBGA package that enables dense board layout while supporting the high pin count needed for multi-channel serial interfaces and wide parallel buses. The C3 speed grade and N suffix indicate a commercial-temperature, lead-free, RoHS-compliant ordering option. The Stratix II GX architecture implements an ALM (Adaptive Logic Module) fabric rather than the classical 4-input LUT, giving finer-grained logic packing and shorter typical critical paths. TriMatrix memory provides three block sizes (MLAB, M512, M4K) with dedicated routing, allowing the FPGA to instantiate single-port, dual-port, shift-register, or ROM structures without consuming general logic. Embedded transceiver CRUs recover clock and data from inbound serial streams without external components. Typical applications include high-speed serial backplane bridging, telecom line-card aggregation, video-broadcast SDI/HD-SDI routing, military secure-radio baseband processing, and ASIC prototyping for protocols that require multi-gigabit serial I/O. Designers use the part when they need a moderate-density FPGA fabric plus 4-20 SERDES channels on a single die to replace a multi-chip PHY + FPGA solution. When laying out a board with the EP2SGX30DF780C3N, dedicate continuous ground and 1.2 V core supply planes under the package, route each transceiver differential pair with 100 ohm differential impedance and length matching to within the datasheet budget, and isolate the PLL analog supplies with their own filtered rails.

The Altera EP2SGX30DF780C4N is a member of the Stratix II GX family of field-programmable gate arrays (FPGAs) with integrated high-speed transceivers, offering 33,880 logic elements and 1,369,728 RAM bits in a 780-ball flip-chip BGA (780-FBGA, 29x29 mm, 1 mm pitch) package. According to the manufacturer datasheet, the device operates from a 1.15 V to 1.25 V core supply and supports up to 622 MHz internal frequency with a -40C to +85C commercial temperature range. The part is a CMOS FPGA fabricated in a 90 nm process, providing 361 user I/O pins and 1,694 logic array blocks (LABs). An FPGA (Field-Programmable Gate Array) is a semiconductor device built around a matrix of configurable logic blocks (CLBs) connected via programmable interconnect. FPGAs sit in the broader taxonomy: programmable logic device (PLD) -> FPGA -> SRAM-based FPGA -> high-performance transceiver FPGA. They are used wherever designers need parallel processing, custom I/O timing, hardware-accelerated DSP, or high-speed serial links that an ASIC, MCU, or DSP cannot economically deliver. The Stratix II GX family specifically targets applications that combine logic density with multi-gigabit transceivers (MGTs) for serial connectivity. Key features include embedded transceiver blocks supporting multiple serial protocols, dedicated DSP blocks for high-throughput signal processing, TriMatrix on-chip memory up to ~1.37 Mbits, and support for source-synchronous and high-speed external memory interfaces (DDR/DDR2/QDR). The device integrates up to 12 transceivers depending on package variant, with per-channel data rates suitable for PCIe, XAUI, Serial RapidIO, and custom serial links. The 780-FBGA package provides 361 user I/Os and a flip-chip thermal path for reliable operation at high toggle rates. Architecturally, Stratix II GX uses an ALM-based adaptive logic module that improves on prior 4-input LUT architectures, increasing effective logic density and reducing fabric congestion. The transceiver tiles are physically isolated and clocked independently from the core fabric, allowing parallel development of high-speed serial and parallel logic on the same die. Configuration is via SRAM, so the bitstream reloads from external flash or a host processor on every power-up. Typical applications include telecommunications line cards, software-defined radio baseband processing, high-speed serial protocol bridging, ASIC prototyping, and high-performance DSP pipelines. Engineers select Stratix II GX for designs that demand both high logic capacity and integrated multi-gigabit serial I/O without the cost and risk of an ASIC. When designing with this part, plan power-rail sequencing carefully because core (1.2 V), PLL analog, and transceiver supplies have separate tolerance bands; failure to sequence them can stress the transceivers during bring-up. Use the Quartus II design suite (legacy) or consult the Stratix II GX handbook for transceiver channel bonding and pre-emphasis settings. The device is now in legacy/EOL status, so verify long-term availability before committing to a new design.

The device is fabricated in a 90nm CMOS process and delivers up to 609.76 MHz internal operation per the FindIC datasheet summary. A Field-Programmable Gate Array (FPGA) is a reconfigurable semiconductor integrated circuit whose logic fabric, routing, and I/O can be electrically programmed after manufacturing, making it part of the programmable logic hierarchy (FPGA -> PLD -> programmable logic -> semiconductor). FPGAs are widely used in applications requiring high-speed parallel processing, custom I/O protocols, and rapid prototyping where ASIC NRE costs are not justified. Stratix II GX parts specifically target high-speed serial I/O designs such as communications, broadcast video, and military/aerospace systems. Key features include 4 transceiver blocks supporting up to 3.125 Gbps per channel, dedicated DDR/DDR2/QDR memory interface hardware with read/write leveling, 16 global clock networks, and enhanced DSP blocks. The device integrates 4 PLL/DLL blocks per quadrant with reprogrammable phase shifts. The 780-ball FBGA (29 x 29 mm, 1 mm pitch) supports up to 361 user I/Os (per Mouser summary) for LVDS, LVTTL, LVCMOS, SSTL, HSTL, and PCI/PCI-X interfacing. The Stratix II GX architecture uses an ALM (Adaptive Logic Module) structure rather than traditional 4-input LUTs, giving finer granularity and lower logic utilization. Transceivers operate from 600 Mbps to 3.125 Gbps with dynamic reconfiguration and support for PCI Express, Serial RapidIO, XAUI, and CPRI protocols. Configuration is via enhanced configuration plus error detection with CRC and watchdog timer. Typical applications include high-speed serial backplanes, broadcast video processing, telecom line cards, PCIe endpoint devices, and DSP co-processing. When designing with this device, ensure the PCB supports 1 mm-pitch BGA breakout with microvia or HDI stack-up, and reference Altera's Stratix II GX Handbook for transceiver channel placement and power distribution network design.

EP2SGX30DF780C5N

EP2SGX30DF780C5N - Stratix II GX FPGA, 33.88k LE, 780-FBGA | Intel

The Intel (formerly Altera) EP2SGX30DF780C5N is a high-performance Stratix® II GX Field Programmable Gate Array (FPGA) delivering 33,880 logic elements, 1,369,728 memory bits, and 361 user I/Os, integrated with up to 24 embedded transceivers supporting multi-gigabit serial interfaces. It is housed in a 780-ball flip-chip FineLine BGA (FC-FBGA) package measuring 29 mm x 29 mm with a 1.0 mm ball pitch, operating from a 1.2 V core supply at a commercial temperature grade of 0°C to +85°C and a -40°C to +85°C extended range. Internal clock networks can reach up to 622 MHz, and the part is fabricated on a 90 nm CMOS process. An FPGA is a semiconductor device whose logic function is defined after manufacturing by a configuration bitstream loaded into on-chip SRAM, as opposed to an ASIC where the function is fixed at tape-out. FPGAs sit in the wider hierarchy: programmable logic device (PLD) → field-programmable gate array (FPGA) → high-density FPGA with embedded transceivers. Stratix II GX parts are specialized for high-speed serial I/O (PCI Express, XAUI, Serial RapidIO, SerialLite II) and combine general-purpose fabric with hardened IP blocks, allowing a single chip to implement bridging, packet processing, and DSP functions that previously required an ASIC plus a discrete PHY. Key features of the EP2SGX30DF780C5N include 1,694 LABs/CLBs, 1694 logic array blocks, total RAM bits of 1,369,728, and an extended industrial operating temperature range. The 'C5' speed grade corresponds to the slower commercial tier while still enabling >600 MHz fabric operation; the 'N' suffix denotes a lead-free, RoHS-compliant finish. The Stratix II GX family supports dedicated DSP blocks, on-chip termination for high-speed transceivers, and the Quartus II design suite for synthesis, place-and-route, and bitstream generation. Architecturally, the device uses an adaptive logic module (ALM) based fabric with 8-input fracturable look-up tables, eight ALMs per LAB, and column-/row-based routing. Embedded transceivers operate from 600 Mbps to 6.375 Gbps depending on the protocol, with embedded PCS/PMA blocks for 8B/10B encoding, rate matching, and word alignment. The part supports source-synchronous DDR/DDR2/QDR II memory interfaces via dedicated DQS circuitry, making it well suited to high-bandwidth memory-to-logic bridging. Typical applications include telecom backplane line cards, broadcast video processing, military radar and signal intelligence, medical imaging front-ends, and ASIC prototyping. The combination of 33k logic elements and embedded multi-gigabit transceivers makes the EP2SGX30DF780C5N particularly attractive for protocols that are now legacy but still in service (XAUI, PCIe Gen1/Gen2, Serial RapidIO). A primary design consideration is power-supply sequencing - the 1.2 V core, 3.3V/2.5V/1.8V I/O banks, and PLL/transceiver auxiliary supplies must ramp in the order specified by the datasheet to avoid in-rush latch-up. PCB layout requires impedance-controlled 100 Ω differential traces for the transceiver channels and matched-length routing for DDR/DDR2 memory interfaces.

EP2SGX30DF780C6 - Stratix II GX FPGA 33.8K LEs | Altera

The Altera EP2SGX30DF780C6 is a member of the Stratix II GX family of high-density, high-performance field-programmable gate arrays (FPGAs) with embedded multi-gigabit transceivers, delivered in a 780-pin FineLine BGA package at commercial speed grade 6. The device integrates 33,880 logic elements, 1,369,728 RAM bits organized in 33,880 memory blocks, and 361 maximum user I/Os, providing a balanced mix of logic, memory and serial connectivity for bandwidth-intensive designs. A field-programmable gate array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable routing, and dedicated hard IP such as block RAM, DSP blocks and (in this family) multi-gigabit transceivers. FPGAs sit at the top of the programmable-logic hierarchy - alongside CPLDs and structured ASICs - and are widely used to prototype, bridge, or pre-produce digital systems that require high I/O counts, parallel processing, or fast serial links. The Stratix II GX family extends that capability with up to 6.375 Gbps transceivers, hard PCI Express and other protocol IP, making the family a bridge between generic FPGAs and structured ASSPs. Key features of the EP2SGX30DF780C6 include 1,694 LABs/CLBs (per Mouser listing for the C4N sibling), 33,880 logic elements, dedicated 18-bit x 18-bit multiplier blocks, and Stratix II adaptive logic modules (ALMs) that pack two 4-input LUTs into a single 7-input equivalent. The device supports both 1.2V core and 1.5V/1.8V/2.5V/3.3V selectable I/O standards through programmable I/O banks, and it integrates multi-gigabit transceivers (MGTs) that handle protocols such as Serial RapidIO, XAUI, PCIe and custom serial interfaces up to 6.375 Gbps. The device is fabricated in a 90 nm process with a 1.2 V core supply, leveraging Altera's adaptive logic module architecture to achieve high logic density at lower power per LE than the original Stratix. Embedded hard IP (MGTs, memory controllers, DSP blocks) frees programmable fabric for application logic, so the part is often used to implement protocol bridging, baseband processing, and high-speed serial aggregation. Typical applications include high-speed serial interface aggregation (XAUI, PCIe, Serial RapidIO), telecom baseband and channel-card designs, military and aerospace signal processing, broadcast video processing, and ASIC prototyping. The 780-pin FBGA package supports 361 user I/Os with 8 Gbps-class serial links, making the device attractive for backplane and line-card designs that need many LVDS pairs plus multi-gigabit serial. When designing with the EP2SGX30DF780C6, plan power sequencing on the 1.2 V core rail, observe Stratix II GX decoupling and PCB layout guidelines from the family handbook, and verify transceiver reference-clock and PCB stack-up requirements against the device's high-speed channel budget. Designers should also confirm Quartus II support for the exact speed grade and pin-out revision before tape-out.

A Field Programmable Gate Array (FPGA) is a reconfigurable semiconductor that combines programmable logic blocks, programmable interconnect, and I/O cells on a single die. FPGAs belong to the broader hierarchy of programmable logic devices (PLD), within the taxonomy of logic ICs > integrated circuits > semiconductors. The Stratix II GX family extends the Stratix II architecture with up to 20 multi-gigabit transceivers (channel data rates to 6.375 Gbps), making the series targeted at high-speed serial I/O, DSP, and embedded processing applications. Key features of the EP2SGX30DF780C7 include 33,880 logic elements (LE), 1,369,728 RAM bits organized as 482 M512/M4K/M-RAM blocks, 24 DSP blocks implementing 192 18x18 multipliers, an FPGA speed grade of -7 (faster than -8), and a commercial operating temperature range of 0C to +85C. The -C7 speed grade denotes a faster timing closure option that allows higher Fmax on internal logic paths than the C5/C6 grades. The EP2SGX30DF780C7 uses a 90 nm process node with a 1.2 V core supply, an embedded transceiver serializer/deserializer (SERDES) tile that supports PCI Express, Serial RapidIO, XAUI, and CEI-6G physical layers, and a fine-pitch 780-ball BGA package with a 1.0 mm ball pitch. Configuration is supported via passive serial (PS), fast passive parallel (FPP), and Joint Test Action Group (JTAG) modes with optional encryption via the EPC configuration device family. Typical applications of the EP2SGX30DF780C7 include high-speed serial interface bridging (PCI Express Gen1/Gen2 endpoints), digital signal processing cards in communications infrastructure, baseband processing in wireless base stations, ASIC prototyping, broadcast video processing, and software-defined radio front-ends. The 6.375 Gbps SERDES capability and abundant DSP blocks make it suitable for data plane packet processing. When designing with this FPGA, pay attention to transceiver reference clock jitter, PCB layer stack-up for BGA breakout, and the need for proper decoupling on every VCC rail. Quartus II software (version 9.0 and later) is the design environment, and the device requires a configuration flash memory if FPP/PS modes are used.

EP2SGX30DF780C7N - 30K LE Stratix II GX FPGA 780-BGA | Altera
EP2SGX30DF780C7N

EP2SGX30DF780C7N - 30K LE Stratix II GX FPGA 780-BGA | Altera

The Altera (now Intel) EP2SGX30DF780C7N is a member of the Stratix II GX family of high-performance FPGAs, delivering approximately 33,880 equivalent logic elements (LEs) and up to 1,369,728 bits of embedded memory in a 780-ball FineLine BGA package. Built on a 90 nm process, this device integrates dedicated 3.125 Gbps transceiver circuitry alongside the adaptive logic module (ALM) fabric, targeting high-speed serial I/O and digital signal processing designs. A Field Programmable Gate Array (FPGA) is a programmable logic IC whose internal lookup tables, flip-flops, routing, and hard IP blocks can be configured by the user after manufacture to implement arbitrary digital functions, ranging from simple glue logic to complete processor subsystems. FPGAs sit in the broader taxonomy of programmable logic devices (PLDs), with high-end FPGAs like Stratix II GX further embedding transceivers, DSP blocks, and large block RAMs to compete with ASICs in throughput-intensive applications. The -7 speed grade places this part in the standard-performance tier of the family, balanced for both timing closure and power. Key features include 361 user I/O pins, dedicated 3.125 Gbps multi-gigabit transceivers (MGTs), embedded multiplier blocks for DSP, and on-chip Phase-Locked Loops (PLLs) for clock management. The FineLine BGA-780 package supports high pin density with controlled-impedance signal integrity for parallel interfaces and serial links. The integrated transceiver hard IP allows designers to implement protocols such as PCI Express, Serial RapidIO, Gigabit Ethernet, and XAUI without consuming general-purpose logic resources. Architecturally, Stratix II GX uses the ALM as its basic logic element, where each ALM contains two adaptive look-up tables (ALUTs) and four programmable registers, giving finer granularity than the 4-LUT structures used in earlier Stratix generations. The transceiver blocks include physical coding sublayer (PCS) and physical medium attachment (PMA) layers to handle 8b/10b encoding, clock data recovery, and serializer/deserializer functions. Combined with the Quartus II design toolchain, this part accelerates time-to-prototype for communication and signal-processing systems. Typical applications include high-speed serial backplanes, telecom line cards, wireless baseband processing, broadcast video routers, and military signal-processing systems. The combination of high logic density, embedded transceivers, and substantial block RAM makes it well suited for protocol bridging, packet processing, and high-throughput DSP pipelines where a hard ASIC would be uneconomical at low volumes. When designing with this device, engineers must allocate sufficient PCB layers (typically 10+ layers) to route the BGA-780 breakout and maintain signal integrity on the transceiver channels. Thermal management must account for the worst-case junction temperature under full transceiver utilization, and power estimation in Quartus II should be run early to size decoupling and the regulator tree correctly.
