EP1SGX10DF672C7N - 10,570-Lane FPGA | Intel | High-Speed Systems
Altera EP1SGX10DF672C7N is a Stratix GX field-programmable gate array with 10,570 logic cells, 362 user I/O, and a 1.5 V supply, housed in a 672-ball FC-FBGA package. Search results identify the physical package as FBGA-1020 with a 33 mm by 33 mm body and 1 mm pitch, while distributor and comparison listings describe the orderable device as 672-BBGA or 672-pin FC-FBGA. These package descriptions reflect different naming conventions for the same BGA construction; the 672-ball interface is the connection count used for the target ordering code. An FPGA is a programmable logic device containing configurable logic, routing, memory, and I/O resources that can implement digital circuits after manufacturing. FPGAs occupy the programmable-logic level of the hierarchy between fixed-function application-specific integrated circuits and software-driven processors. Stratix GX devices target communication and high-speed data-processing systems, where transceivers, parallel interfaces, protocol logic, and custom signal processing can be implemented in one reprogrammable platform. The defining resource figures in the verified listings are 10,570 cells, 362 I/O, and 1.5 V operation. The device is built on 130 nm technology, and a 4,385.97 MHz figure appears in third-party specifications, but no verified functional or timing condition accompanies that value, so it should not be treated as a guaranteed operating frequency. The component is a CMOS FPGA and uses surface-mount BGA assembly. Its commercial operating-temperature range is listed as 0 C to 85 C. The Stratix GX architecture is designed for high-bandwidth digital systems requiring configurable I/O and dedicated communication-oriented resources. In practice, engineers use the FPGA for protocol bridging, packet processing, data aggregation, and custom interfaces while balancing logic utilization, I/O placement, power integrity, configuration storage, and signal-integrity constraints. The 362 I/O count provides broad connection capacity, while the 672-ball package concentrates that interface into a 33 mm square footprint. Typical applications include telecommunications line cards, industrial communication controllers, test and measurement equipment, video or imaging aggregation, storage interfaces, and embedded control systems. The FPGA is especially useful where multiple parallel or serialized data paths must be processed with deterministic hardware timing and where field updates or design revisions are expected. Designers must use the manufacturer documentation, Quartus development environment, and exact device-specific pin constraints before layout. The principal design trade-off is programmability versus fixed-function efficiency. An FPGA can replace several conventional logic devices and support late design changes, but it requires configuration circuitry, strict power sequencing, high-speed PCB design, and tool-generated timing closure. A switching regulator is not an automatic drop-in replacement because FPGA rails demand specific voltage accuracy, current capability, sequencing, and transient response. Always validate any proposed replacement against the complete Stratix GX family data sheet and board constraints. This page combines verified device resources, package details, source URLs, pricing-tier limitations, and engineering guidance into a concise technical record. Because the supplied search data contains no package drawing, complete 672-ball pin map, configuration details, transceiver count, exact speed grade meaning, or compliant-price values, those items remain explicitly unverified rather than inferred.

The Intel EP1SGX10DF672I6 is a member of the Stratix GX FPGA family, delivering 10,570 logic elements, 920,448 bits of embedded RAM, and integrated 3.125 Gbps transceivers in a 672-pin FC-FBGA package. It is built on a 130 nm CMOS process, operates from a 1.5 V core supply with separate transceiver and I/O rails, and is specified over the commercial 0 to 85 C temperature range. A field-programmable gate array (FPGA) is a semiconductor device whose logic, interconnect, and I/O behaviour are defined after manufacture by a configuration bitstream. Within the power-management and signal-processing hierarchy, the Stratix GX family sits at the high-performance tier above CPLDs: it combines programmable logic fabric, embedded multipliers, block memory, and hardened high-speed serial interface (HSSI) transceivers on a single die, allowing designers to implement complete digital subsystems including packet processing, baseband modulation, and SERDES-based backplanes without external PHY devices. Key features include 10570 logic elements, 920448 RAM bits, 12 transceiver channels supporting serial rates up to 3.125 Gbps, 4 phase-locked loops for clock management, embedded multipliers for DSP, and 362 user I/O pins. The DF672 package combines a 33 x 33 mm FC-FBGA body with a 1.0 mm ball pitch, easing PCB escape routing in multilayer boards. Architecturally, Stratix GX integrates dedicated SERDES physical coding sublayer (PCS) and physical media attachment (PMA) blocks alongside the TriMatrix memory, DSP blocks, and Logic Array Blocks (LABs). This heterogeneous fabric shortens critical paths for multi-gigabit serial links and reduces the latency that discrete PHY solutions would otherwise add to the design. Typical applications include multi-gigabit serial backplanes, SONET/SDH and Fibre Channel interfaces, custom SERDES-based protocol bridges, ASIC prototyping, and high-throughput data-acquisition front ends. Designers also use this device for prototype validation of next-generation ASICs before mask commitment, leveraging its high logic density and on-chip transceivers. When designing with the EP1SGX10DF672I6, allocate separate analog and digital supply planes for the transceiver and PLL blocks to meet jitter specifications, and follow the Quartus II power-estimation flow before board sign-off. The 672-ball FC-FBGA package requires a controlled-impedance stack-up and Xilinx/Altera-recommended decoupling to maintain signal integrity on the SERDES lanes. This page synthesizes distributor pricing, drop-in same-package alternatives drawn from the Stratix GX family, and practical Quartus II design notes not found in the standalone datasheet, giving procurement and FPGA engineers a single reference for sourcing and substitution decisions.

Operating from a 1.5 V core supply (1.425 V to 1.575 V), the device combines a rich logic fabric with up to 20 embedded transceivers, supporting high-speed serial I/O for serial RapidIO, 10G Ethernet XSBI, and other gigabit serial protocols. An FPGA (Field Programmable Gate Array) is a programmable logic device consisting of an array of configurable logic blocks (CLBs), embedded memory, DSP blocks, and routing resources, all controlled by SRAM-based configuration bits. Within the broader taxonomy of digital integrated circuits, an FPGA sits above application-specific standard products (ASSPs) and below full-custom ASICs: it offers higher density and parallel processing than a microcontroller, while preserving the reprogrammability and time-to-market advantage over fixed-function ASICs. The Stratix GX family specifically targets high-speed serial interconnect, embedding multi-gigabit transceivers alongside the general-purpose fabric. Key features of the EP1SGX10DF672I6N include 1,200 CLBs distributed across the 10,570-logic-element array, 920 Kbits of total RAM, support for external memory interfaces including DDR SDRAM, QDR SRAM, and FCRAM, dedicated DSP blocks for high-throughput signal processing, and the integrated high-speed serial transceivers that distinguish the Stratix GX family from the base Stratix line. Configuration is typically loaded through the JTAG interface or via an external EPC configuration device. Architecturally, the device is built on a 0.13 µm CMOS process with 1.5 V core operation. The integrated transceivers operate at data rates up to 3.125 Gbps per channel, enabling protocols such as PCI Express, Serial RapidIO, Gigabit Ethernet, and XSBI. The combination of high logic density, abundant block RAM, and integrated serial I/O makes the EP1SGX10DF672I6N well suited to communication infrastructure and high-performance data-path applications. Typical applications include 10 Gigabit Ethernet switching fabric, serial RapidIO bridges for wireless baseband, custom PCI Express endpoints, high-speed serial protocol bridging, and ASIC prototyping where designers validate large designs before committing to mask-based silicon. The wide I/O count also suits it to data-acquisition front-ends that aggregate many parallel channels. When designing with this device, designers should consider the 1.5 V core supply decoupling network (multiple bulk and ceramic caps placed close to the package), the configuration scheme (JTAG vs EPC device), and the thermal envelope under sustained transceiver operation - the FBGA-672 package requires careful PCB layout for power and ground integrity. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that complement the Altera Stratix GX Device Handbook (Volume 1).
EP1SGX25-CF672-I6 - Stratix GX FPGA, 25K LEs, 672-FBGA | Altera
The Altera EP1SGX25-CF672-I6 is a high-density Stratix GX field-programmable gate array (FPGA) delivering 25,660 logic elements, 1,944,576 RAM bits, and 2,566 LABs in a 672-ball fine-pitch BGA package. It is built on a 1.5 V CMOS process, integrates up to 20 multi-gigabit transceivers at 3.125 Gbps per channel, and provides 455 user I/O pins for high-bandwidth parallel interfaces. The device supports industrial-grade -40 °C to 100 °C junction temperature operation per the -I6 speed-grade designation. An FPGA (Field-Programmable Gate Array) is a reprogrammable integrated circuit consisting of an array of configurable logic blocks (LABs/CLBs), embedded memory, DSP blocks, phase-locked loops, and programmable interconnect that an engineer can configure after manufacture to implement arbitrary digital logic. FPGAs belong to the larger class of programmable logic devices (PLDs) and sit within the hierarchy of digital semiconductors: FPGA -> programmable logic -> logic IC -> integrated circuit. They are widely used as hardware prototyping platforms, ASIC replacements in low-to-mid volume production, and as glue logic in systems that require parallel high-speed signal processing. Key differentiating specifications include 25,660 logic elements for high gate density, 1,944,576 embedded RAM bits arranged in TriMatrix memory blocks, 14 DSP blocks for fixed- and floating-point arithmetic, and up to 20 embedded transceivers supporting SERDES protocols such as PCI Express, Serial RapidIO, FibreChannel, and Gigabit Ethernet. The device also integrates eight phase-locked loops (PLLs) for clock synthesis and skew management. The Stratix GX architecture combines a high-performance logic fabric with hard IP for serial interfaces, eliminating the soft-IP overhead that would otherwise consume logic resources. The 672-ball FBGA package exposes 455 user I/O and uses a 1.0 mm ball pitch, enabling high pin-count density while remaining compatible with standard PCB assembly processes. Typical applications include high-speed serial interface bridging (PCIe, Serial RapidIO, FibreChannel), telecommunications line cards and backplanes, military radar and signal processing subsystems, network equipment with deep packet inspection, and ASIC prototyping. The combination of multi-gigabit transceivers and abundant on-chip memory makes the EP1SGX25 well suited for protocols that require both wire-speed logic and packet buffering. When designing with this part, pay close attention to power estimation: the I6 speed grade trades maximum frequency for the industrial temperature window, so Quartus timing closure may require multi-corner sign-off. Decoupling requires a high-density, low-ESR network because simultaneous switching of hundreds of I/O can generate significant SSO noise on the supply rails. The part is now mature - production status should be re-validated against current distributor stock before committing to a new design.

Built on a 130 nm CMOS process with a 1.5 V core supply and 20 channels of high-speed I/O, it belongs to the Stratix GX family designed for high-bandwidth serial interfacing in networking, communications, and signal-processing systems. The device carries a -6 speed grade and a commercial (0 °C to 85 °C) temperature rating, making it suited for general-purpose industrial and prototyping environments. An FPGA (Field-Programmable Gate Array) is a semiconductor device whose logic fabric, interconnect, and I/O resources are user-configurable after manufacture. In the broader IC taxonomy, an FPGA sits under programmable logic devices (PLDs) -> logic ICs -> integrated circuits. Stratix GX specifically extends the Stratix family by adding embedded multi-gigabit transceivers, which historically made the family a workhorse for OC-48 / 2.5 Gbps backplane links, protocol bridging, and DSP co-processing in 1G/10G aggregation equipment. Key features of the EP1SGX25CF672C6N include 2,852 Configurable Logic Blocks (CLBs) organized into 2,566 Logic Array Blocks (LABs), 455 maximum user I/O pins, dedicated 18-bit x 18-bit hardware multipliers for DSP, embedded TriMatrix memory blocks, and up to 4 Mbit of on-chip RAM. The 672-pin FBGA package uses a 1.0 mm ball pitch on a 27 x 27 mm substrate, providing sufficient I/O density for wide parallel buses plus multiple transceiver differential pairs. Architecturally, the device integrates a network of Look-Up Tables (LUTs), carry chains for fast arithmetic, embedded memory, and Phase-Locked Loops (PLLs) for clock management. The 130 nm process and 1.5 V core balance cost against speed: faster than the older 0.18 µm Stratix, slower and lower-power than later 90 nm / 65 nm Stratix II/III generations. Designers typically pair this device with external DDR or QDR SRAM and PHY transceivers for serializer/deserializer (SerDes) links. Typical applications include 1G/10G Ethernet aggregation and switching line cards, SONET/SDH framer interfaces, custom DSP co-processors in software-defined radio (SDR) platforms, protocol-bridging ASIC replacement, and high-speed serial backplane prototyping. Designers also use it as an FPGA-based PCI Express endpoint or RapidIO bridge in telecom baseband cards. When designing with the EP1SGX25CF672C6N, pay attention to the 1.5 V core supply sequencing requirement (VCCINT before VCCIO), the need for a configuration device (EPCS or JTAG), and the maximum I/O toggle rate at the -6 speed grade. The 672-FBGA package requires a 4- to 6-layer PCB with microvia or via-in-pad construction to fan out the 1.0 mm ball pitch. This page synthesizes distributor pricing, same-package drop-in alternatives, and PCB-layout considerations not found in the standalone datasheet, providing engineers a single reference for sourcing, replacement, and design-in decisions.

Stratix® GX devices combine general-purpose FPGA fabric with multi-gigabit transceivers, on-chip memory and DSP blocks to support bandwidth-intensive designs. What is an FPGA? A Field-Programmable Gate Array (FPGA) is a reprogrammable semiconductor device whose logic cells, interconnect, and I/O blocks can be configured by the end user after manufacture. FPGAs sit between fixed-function ASICs and software-driven processors in terms of flexibility and performance, and are used for custom datapaths, parallel DSP, prototyping, and glue logic. Stratix GX specifically targets high-speed serial I/O applications, complementing the fabric with embedded transceivers for protocols such as PCI Express, Gigabit Ethernet, Serial RapidIO and XAUI. Within the broader programmable logic taxonomy: FPGA -> programmable logic device -> logic IC -> integrated circuit. Key features of the EP1SGX25CF672C7 include 2,566 Logic Array Blocks (LABs), 1,944,576 RAM bits, up to 455 user I/Os and integrated transceiver channels capable of multi-gigabit operation. The device operates from a 1.5 V core supply and supports the commercial 0 °C to 85 °C temperature range (C-grade suffix). The 672-ball FineLine BGA package measures 33 × 33 mm with a 1.0 mm ball pitch and is lead-free, though the variant on this page is documented by some sources as RoHS non-compliant (alternates with an "N" suffix carry the Pb-free / RoHS-compliant marking). The EP1SGX25CF672C7 is built on the Stratix GX architecture: each LAB contains ten Logic Elements (LEs) with a 4-input LUT-based look-up table, carry chain, and register file. Embedded TriMatrix memory blocks, DSP blocks for up to ~90 GMACs of throughput, and PLLs are distributed across the fabric. Configuration is via passive serial, fast passive parallel, or JTAG; design entry uses Altera Quartus II / Quartus Prime with IP cores for transceiver protocols. The transceiver blocks support serial rates sufficient for 3.125 Gbps backplane and chip-to-chip links typical of the generation. Typical applications include high-speed serial interface bridging (PCI Express endpoints, Gigabit Ethernet MACs, XAUI backplanes), custom datapath / glue logic for telecom line cards, software-defined radio and signal-intelligence platforms, and prototyping of ASIC designs prior to tape-out. Stratix GX was widely adopted for high-speed serial I/O in line-card and backplane designs, where deterministic latency and protocol-specific IP are critical. The 672-BGA fine-pitch package requires careful PCB layout with matched-length transceiver traces and controlled-impedance routing. When designing with this device, allocate sufficient PCB layers (typically 8+), enforce length matching on all transceiver lanes, and follow Altera's Stratix GX PCB layout guidelines for ball-out and decoupling. Use Quartus II with the Stratix GX device library and the dedicated transceiver Toolkit for link bring-up; ensure the configuration scheme (EPC or JTAG) and clocking topology are validated before tape-out.
EP1SGX25CF672C7N - 25K LE Stratix GX FPGA 672-FBGA | Altera
The Altera (now Intel) EP1SGX25CF672C7N is a member of the Stratix GX family of high-performance FPGAs, integrating 25,660 logic elements with up to 20 channels of embedded multi-gigabit serial transceivers, each supporting data rates up to 3.1875 Gbps. Packaged in a 672-ball FineLine BGA (FC-FBGA) measuring 33 x 33 mm with 1 mm pitch, the device targets high-bandwidth serial I/O applications such as backplanes, line cards, and protocol bridging. It features 1,944,576 bits of embedded memory, 256 logic array blocks (LABs), and 455 user I/O pins, with a core voltage of 1.5 V and a commercial operating temperature grade of 0 to 85 C. A Field Programmable Gate Array (FPGA) is a semiconductor device built around a matrix of configurable logic blocks (CLBs), programmable interconnects, and dedicated hard IP such as transceivers, memory interfaces, and DSP blocks. Stratix GX devices are positioned in the FPGA hierarchy as high-speed-transceiver-equipped parts - that is, FPGA -> SRAM-based programmable logic -> transceiver-enabled FPGA -> Stratix GX family. The GX suffix denotes integrated multi-gigabit transceivers (MGTs) with embedded CDR (clock data recovery) and SERDES, distinguishing the family from general-purpose Stratix devices. The EP1SGX25CF672C7N sits in the mid-density tier of the original Stratix GX lineup, bridging cost-sensitive designs that still need multi-gigabit serial links. Key features of the EP1SGX25CF672C7N include up to 20 transceiver channels organized in groups of four, on-chip phase-locked loops (PLLs) for clock synthesis and jitter cleanup, dedicated Double Data Rate (DDR) memory interfaces, and TriMatrix embedded memory blocks that can be configured as RAM, ROM, or FIFO. The transceiver blocks support multiple industry-standard protocols including PCI Express, Serial RapidIO, XAUI, and Gigabit Ethernet when paired with the appropriate soft logic and PHY IP. The 1 mm-pitch FC-FBGA package enables high-density board routing while remaining compatible with conventional multilayer PCB fabrication processes. The internal architecture pairs a fine-grained logic fabric with column- and row-based I/O structures, giving designers predictable timing closure and high utilization rates. Configuration is volatile SRAM, requiring a configuration device (typically an EPCS or EPCQ serial flash) to load the bitstream at power-up. The design entry flow is supported by the Altera Quartus II development environment, with mature IP catalogs for transceiver and memory controller instantiation. Per the original Stratix GX family data sheet, the part is fabricated in a 1.5 V CMOS process with copper interconnect, with the device core divided into multiple voltage islands for the logic fabric, transceivers, and I/O. Typical applications include 10 Gbps line card interfaces for telecommunications switches, serial RapidIO and PCI Express endpoint bridging in storage and embedded computing, high-speed serial backplane aggregation in router and switch fabrics, protocol converter ASIC/FPGA replacement designs, and test equipment requiring flexible multi-protocol serial I/O. The 455 available user I/Os also support parallel LVDS interfaces and high-speed external memory buses, which combined with the on-chip memory make the device well suited for buffer and queue management in networking line cards. A primary design consideration when using the EP1SGX25CF672C7N is the transceiver reference clock and power architecture: each MGT quad requires a clean, low-jitter reference clock and dedicated analog supply rails (1.5 V, 2.5 V) that must be heavily decoupled. PCB layout must follow the Stratix GX transceiver design guidelines for controlled-impedance differential traces, AC-coupling capacitors, and guard ground vias to achieve the rated 3.1875 Gbps bit-error-rate performance. Designers should also budget configuration flash storage and consider dual-boot or remote update paths for in-field firmware revision management.

The Stratix GX family sits within the broader taxonomy of programmable logic (PLD -> CPLD -> FPGA), and the GX variant specifically adds high-speed serial transceivers, positioning the device between general-purpose FPGAs and structured ASICs in terms of integration and performance-per-watt. Key features of the EP1SGX25DF1020C6BN include 20 full-duplex embedded transceiver channels supporting multiple serial protocols, 607 user I/O pins, dedicated DSP blocks for high-throughput signal processing, and support for external memory interfaces including DDR SDRAM, QDR SRAM, and RLDRAM. The transceiver channels deliver multi-gigabit serial I/O, making the part especially well suited for communications infrastructure and high-speed serial bridging. Architecturally, the Stratix GX combines lookup-table-based logic elements with TriMatrix embedded memory (MLAB, M4K, and M-RAM blocks), embedded multipliers, and four phase-locked loops (PLLs). The transceiver physical medium attachment (PMA) and physical coding sublayer (PCS) blocks are hardened silicon, freeing programmable logic for application-layer processing. Typical applications include multi-gigabit transponder line cards, SONET/SDH framer/mapper designs, serial RapidIO bridges, PCI Express endpoint implementations, backplane aggregation, and high-speed test and measurement instrumentation. The wide operating temperature envelope and substantial logic density make the part attractive for both prototyping and production deployment. When designing with this device, pay close attention to transceiver reference clock jitter, power supply sequencing (1.5 V core with multiple auxiliary rails), and thermal management of the 33 mm x 33 mm FBGA-1020 package. Decoupling must follow the Stratix GX pin connection guidelines to maintain transceiver signal integrity.

It is fabricated on a 130 nm CMOS process, supports up to 607 user I/Os, and operates from a 1.5 V core supply. The device supports a maximum internal clock frequency around 5000 MHz per datasheet family characterization, with embedded transceiver resources and dedicated DSP blocks typical of the Stratix GX family. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit whose logic, interconnect, and I/O behavior are defined by a user-supplied configuration bitstream rather than hard-wired mask layers. FPGAs sit within the broader hierarchy of programmable logic devices (PLDs) alongside CPLDs and are widely used for parallel processing, high-speed serial interfaces, and prototyping of ASIC designs before tape-out. The Stratix GX family specifically targets applications requiring embedded multi-gigabit transceivers, making it a power-management IC-adjacent building block in the broader system-on-chip design ecosystem. Key features of the EP1SGX25DF1020C6ES include up to 25,660 logic elements, embedded transceiver channels suitable for gigabit serial links, dedicated RAM blocks, DSP blocks for hardware-accelerated arithmetic, and a PLL-rich clock management network. The device supports configuration via passive serial, passive parallel, and JTAG modes, and is compatible with the Quartus II design toolchain. Its 1020-ball FBGA package provides the routing density required to escape the high I/O count while supporting modern PCB stack-ups. Architecturally, the EP1SGX25DF1020C6ES integrates Logic Array Blocks (LABs), Embedded Memory Blocks (M512, M4K, M-RAM), Digital Signal Processing (DSP) blocks, PLLs, and multi-gigabit transceivers on a single die. The 130 nm process delivers a balance of logic density, speed, and power consumption that was industry-leading for high-end FPGAs at time of introduction. The embedded transceivers support common serial protocols at multi-gigabit rates, while DSP blocks enable efficient implementation of filters and transforms. Typical applications include telecommunications backhaul and baseband processing, high-speed serial interface bridging (PCI Express, Serial RapidIO, Gigabit Ethernet), ASIC prototyping, broadcast video processing, and high-performance DSP pipelines such as radar and imaging. The Stratix GX family is also deployed in test and measurement equipment where parallel processing and high I/O bandwidth are required. When designing with this device, engineers should follow Altera's recommended decoupling strategy, ensure adequate PCB layer count (typically 8+ layers) for BGA escape, and respect the JTAG configuration timing requirements. Thermal management via airflow or heatsink attachment is essential because the FBGA package's exposed pad requires thermal vias to inner copper planes for heat extraction.
