EP1SGX40DF1020C7N - 41,250-Cell Stratix GX FPGA | Altera/Intel

The Intel/Altera EP1SGX40DF1020C7N is a high-density Stratix GX family FPGA with 41,250 logic cells, 624 user I/Os, and integrated transceiver support, housed in a 1020-pin flip-chip FBGA (33x33 mm, 1.0 mm pitch) package. It operates at a core supply of 1.5 V and supports commercial-temperature 0C to +85C operation. The device is built on a 130 nm CMOS process and targets high-bandwidth serial I/O and DSP-intensive applications. A Field Programmable Gate Array (FPGA) is a programmable logic device that lets engineers implement arbitrary digital logic, memory blocks, DSP pipelines, and high-speed serial interfaces in a single chip. FPGAs sit between fixed-function ASICs and software-programmable processors: unlike ASICs they are reconfigurable after fabrication, and unlike processors they achieve deterministic, parallel hardware performance. The Stratix GX family in particular adds multi-gigabit transceivers and dedicated SERDES blocks, positioning it as a programmable alternative to custom silicon for wired communications and high-performance DSP. Key features of the EP1SGX40DF1020C7N include 4,697 Configurable Logic Blocks (CLBs), built-in clock management, embedded memory, and DSP blocks. It supports the Quartus II design flow (legacy versions of Quartus Prime are also backward-compatible). The 1020-pin FC-FBGA package provides the high pin density required for 624 user I/Os plus transceiver and global clock pins. According to the Stratix GX Family Data Sheet, the device supports multi-gigabit transceivers operating in the hundreds-of-MHz to multi-Gbps range, making it suitable for protocols such as SPI-4.2, RapidIO, and 10 Gigabit Ethernet PHY interfaces. Typical applications include telecom line cards, baseband processing, high-speed serial bridging, video processing, and ASIC prototyping. Designers choose this device when they need a balance of logic density, embedded memory/DSP, and high-speed serial I/O without migrating to a fully custom ASIC. Note that the Stratix GX family is mature/last-time-buy; new designs should evaluate Cyclone, Arria, or Stratix V families unless legacy compatibility is required. When designing with this FPGA, plan the PCB for the 33x33 mm BGA with 1.0 mm pitch: use 0.8 mm via-in-pad or microvia stackups with ENIG or ENEPIG surface finish for reliable BGA assembly, and provide at least 6 signal layers with controlled-impedance routing for the transceiver lanes. Decouple every VCC/VCCINT/VCCIO ball with 0.1 uF plus bulk capacitance per the Stratix GX pin connection guidelines.

As Altera's second-generation FPGA to combine multi-gigabit transceivers with a high-performance logic fabric, it targets protocols such as PCI Express, Serial RapidIO, XAUI, and SATA through embedded physical coding sublayers. A Field-Programmable Gate Array (FPGA) is a reconfigurable semiconductor device built from an array of programmable logic elements, routing interconnects, embedded memory blocks, and dedicated I/O resources. Within the broader integrated-circuit hierarchy, an FPGA sits between general-purpose microcontrollers and application-specific integrated circuits (ASICs): it provides hardware-level parallelism and deterministic timing that microcontrollers cannot match, while preserving post-fabrication reprogrammability that ASICs do not offer. The Stratix GX family extends this concept by adding multi-gigabit transceivers, making the FPGA a true system-on-chip for high-speed serial I/O. Key features of the EP1SGX40F1020 include 3,423,744 bits of embedded RAM distributed across TriMatrix memory blocks, 624 user I/O pins, dedicated DSP blocks for high-throughput signal processing, and embedded hard IP for PCI Express ×8 and Serial RapidIO. The device supports configuration via SRAM-based LUTs, allowing in-system reprogramming and remote field upgrades. Its transceiver channels operate from 600 Mbps to 3.1875 Gbps per channel, depending on speed grade, and support both chip-to-chip and backplane signalling. The architecture combines a high-performance adaptive logic module (ALM) fabric with embedded memory, multipliers, and phase-locked loops (PLLs). This heterogeneous mix enables the device to handle packet processing, encryption, video bridging, and baseband functions on a single die while sustaining line-rate throughput on its serial links. Typical applications include high-end communications infrastructure (10 GbE line cards, ATCA backplanes), broadcast and video processing, military signal intelligence, medical imaging accelerators, and ASIC prototyping. The combination of transceivers and dense logic also makes it suitable for test-and-measurement instrumentation where custom signal-conditioning pipelines are required. When designing with this device, careful attention to transceiver power-supply decoupling, channel-bonded clock distribution, and PCB stack-up for 3+ Gbps signalling is critical. JTAG boundary-scan and the active serial configuration scheme simplify board bring-up, but the 1020-ball FineLine BGA demands advanced PCB fabrication and assembly capability.

Built on a 1.5 V core CMOS process, this device combines high-speed serial I/O with a scalable logic fabric, targeting communication infrastructure, high-end test equipment, and signal-processing designs. A field-programmable gate array (FPGA) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs) interconnected by a programmable routing matrix. Within the broader semiconductor hierarchy, FPGAs sit between general-purpose processors (CPUs/MCUs) and application-specific integrated circuits (ASICs): they offer ASIC-class parallelism and throughput while remaining reprogrammable, making them ideal for low-to-medium-volume designs, rapid prototyping, and designs whose algorithms evolve over the product lifecycle. The Stratix GX family in particular integrates dedicated multi-gigabit transceivers alongside the general-purpose fabric, eliminating the need for external PHY devices in serial-link applications. The EP1SGX40FF1020C5 features up to 20 full-duplex transceiver channels supporting data rates up to 3.125 Gbps, embedded RAM blocks totaling approximately 3.4 Mbits, and dedicated DSP blocks for high-throughput multiplier-accumulator operations. The device is offered in a 1020-ball flip-chip BGA with 1.00 mm ball pitch and a seated height of 3.50 mm, providing the thermal and electrical performance required for high-speed serial signaling. Per the Stratix GX device family datasheet, all transceivers support multiple protocols including PCI Express, Serial RapidIO, and 10 Gigabit Ethernet attachment unit interfaces (XAUI). Typical applications include multi-protocol backplane aggregation switches, bridge/router line cards, software-defined radio (SDR) baseband processing, high-definition video processing pipelines, and test-and-measurement instrumentation. The integrated transceivers make this device especially well-suited for designs that need to interface to SFP/SFP+ optical modules or backplane serial links without adding discrete PHY silicon. The 1.5 V core (1.425 V to 1.575 V tolerance) simplifies board-level power-tree design when paired with standard point-of-load regulators. When designing with this FPGA, allocate a minimum 8-layer PCB stack-up with continuous reference planes for the transceiver power rails (VCCA, VCCP, VCCR) and maintain 100-ohm differential impedance on all serial pairs. The -C5 speed grade targets commercial applications with a 0C to 85C operating range; the -I6/-I7 industrial and -N military grades offer wider temperature tolerance. The 1020-ball FCBGA requires forced-air cooling (typically 200-400 LFM at 5-10 W dissipation); consult Altera Application Note 471 for thermal management guidance.

The Altera (Intel) EP1SGX40GF1020C6 is a high-density Stratix GX family Field-Programmable Gate Array (FPGA) delivering 41,250 logic elements (LEs), 3,423,744 bits of embedded RAM, and 624 user I/Os in a 1020-ball Fine-pitch Ball Grid Array (FC-FBGA) measuring 33 mm × 33 mm with a 1.0 mm ball pitch. The device is fabricated on a 0.13 µm CMOS process, operates from a 1.5 V core supply (1.425 V – 1.575 V), and is rated for the commercial 0 °C to 85 °C temperature range. Built-in high-speed transceiver channels and dedicated DSP blocks make it a flagship device of the Stratix GX generation for serial connectivity and DSP-intensive designs. What is a Stratix GX FPGA? An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit whose logic fabric, routing, and I/O can be reconfigured by the designer after manufacture. The Stratix GX sub-family adds multi-gigabit serial transceivers and dedicated hard IP for protocols such as PCI Express, Serial RapidIO, and Gigabit Ethernet, placing it in the broader hierarchy: FPGA → programmable Logic Device → digital Integrated Circuit → semiconductor. The 'GX' suffix distinguishes the transceiver-rich variant from the base Stratix family. Key feature highlights of the EP1SGX40GF1020C6 include 14 embedded DSP blocks for high-throughput signal processing, 4125 LABs (Logic Array Blocks) carrying 10 LEs each, support for configuration via passive serial, fast passive parallel, or JTAG, and a wide range of user I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and HSTL. The 1020-ball FC-FBGA package exposes the full feature set of the silicon and requires careful PCB layout for power, ground, and high-speed signal integrity. Architecturally, the device combines a fine-grained LE fabric with embedded memory columns, multipliers, PLLs, and up to 20 high-speed transceiver channels (channel count varies by speed grade). The 'C6' speed grade balances timing closure margin against maximum operating frequency for cost-sensitive applications. Typical applications include high-speed serial interface bridging (PCI Express ×4/×8 endpoints, Serial RapidIO switches, 10 GbE MAC/PHY interconnects), telecom line-card backplane aggregation, military radar signal processing, ASIC prototyping, and high-performance DSP pipelines in test-and-measurement equipment. Its 41,250 LEs and 3.4 Mbit of block RAM are sufficient to host soft processor cores such as Nios II alongside custom accelerators. Designers should plan power-delivery networks for the 1.5 V core as well as separate PLL, transceiver, and I/O banks; the FC-FBGA-1020 package demands microvia PCB technology and a controlled-impedance stack-up. Verify signal-integrity simulations against the speed grade before tape-out, since the 'C6' grade trades maximum frequency for lower cost. This page synthesizes distributor pricing, verified specifications, drop-in Stratix GX alternatives, and PCB-aware design guidance not found in the manufacturer datasheet alone, giving procurement and hardware engineers a single decision-ready reference.

EP1SGX40GF1020C6B

EP1SGX40GF1020C6B - 41k LE Stratix GX FPGA | Altera | 1020-FBGA

The Altera (Intel) EP1SGX40GF1020C6B is a high-density, high-performance Stratix GX Field-Programmable Gate Array (FPGA) housed in a 1020-ball FineLine BGA (FBGA) package measuring 33x33 mm. The device integrates approximately 41,250 logic elements (4x more LE density than the smallest Stratix GX family member), 3.4 Mbits of embedded TriMatrix memory, 14 embedded DSP blocks, and up to 624 user I/O pins for high-bandwidth system interconnect. The 'C6' speed grade and 'B' industrial temperature suffix make it suitable for mainstream commercial-to-industrial applications. The 'GF' package suffix identifies the Flip-Chip BGA with 1020 balls in a 33x33 mm body optimized for high-pin-count line cards and backplane interfaces. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit built around a configurable logic-block matrix connected by programmable interconnect. Unlike an ASIC, an FPGA's logic function is defined post-manufacture via a configuration bitstream loaded into on-chip SRAM, allowing hardware re-use across product revisions and faster time-to-market. The Stratix GX family extends the original Stratix architecture with embedded transceivers, dedicated DSP blocks, and large TriMatrix memory blocks, placing Stratix GX in the system hierarchy as: FPGA -> programmable logic -> digital ASIC alternative -> semiconductor IC. Key features of the EP1SGX40GF1020C6B include 20 dedicated high-speed transceivers capable of up to 3.125 Gbps operation for serial RapidIO, PCI Express, Gigabit Ethernet, and custom serial protocols; an on-chip phase-locked loop (PLL) array for multi-clock-domain synthesis; and up to 624 user I/O organized into multiple I/O banks supporting LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards at voltages from 1.5 V to 3.3 V. The TriMatrix memory subsystem provides true dual-port RAM, simple dual-port RAM, and FIFO primitives that accelerate packet buffering and DSP working-storage operations. 14 DSP blocks each contain four 18x18 multipliers with optional 36-bit accumulation, delivering roughly 14 GMACS performance at the -6 speed grade. The architecture uses a 1.5 V core supply with 0.13-micron CMOS process technology and SRAM-based configuration, allowing unlimited reconfiguration in-system via JTAG, Passive Serial, Passive Parallel Synchronous, or Passive Parallel Asynchronous modes. The Altera Quartus II design suite supports the device with IP cores for PCI Express, RapidIO, DDR/DDR2 memory controllers, and high-speed serial interfaces, enabling system designers to integrate multiple discrete components into a single programmable device. The 1020-FBGA package requires a multi-layer PCB with controlled-impedance routing and ball-grid-array fanout expertise, and the 33x33 mm footprint demands thermal vias and a thermal pad for sustained operation. Typical applications include high-speed serial backplane interfaces (RapidIO, PCI Express switching fabrics), 10-Gigabit Ethernet line cards, telecom base-station channel cards, military and aerospace signal processing, and high-performance ASIC prototyping. The combination of 624 user I/O and 20 transceivers makes the EP1SGX40GF1020C6B particularly attractive for I/O-rich line cards where the host ASIC is not yet ready in silicon. Industrial-grade temperature range supports outdoor and uncontrolled-environment deployments. Designers should plan for the configuration scheme (EPC16 or EPC64 configuration memory, JTAG boundary-scan for production test), power-supply sequencing for the 1.5 V core and 3.3 V/2.5 V auxiliary rails, and SignalTap II embedded logic analyzer for post-silicon debug. Compared with smaller Stratix GX devices, the EP1SGX40 gives roughly 4x more logic and 14x more DSP throughput, justifying the 1020-FBGA footprint in line-card designs that need both density and bandwidth. Verify PCB footprint against the Altera package symbol library before board fab.

EP1SGX40GF1020C6BN - 41,250 Cells Stratix GX FPGA | Intel

The Intel (formerly Altera) EP1SGX40GF1020C6BN is a high-density Stratix GX family Field Programmable Gate Array (FPGA) with 41,250 logic elements/cells, 3,423,744 bits of embedded memory, and integrated high-speed transceivers in a 1020-pin FineLine BGA (FBGA) package. It is built on a 130 nm process technology, operates from a 1.5 V core supply, and is rated for 624 user I/O pins with a clocking fabric capable of 5,000 MHz performance in fast PLLs. The 'GX' suffix indicates embedded 3.125 Gbps multi-gigabit transceivers, historically used for serial RapidIO, PCI Express, XAUI, and custom high-speed serial links. What is an FPGA? An FPGA (Field Programmable Gate Array) is a semiconductor device whose digital logic function is defined after manufacturing by loading a user-supplied configuration bitstream. FPGAs sit in the programmable-logic branch of digital ICs alongside CPLDs, structured ASICs, and standard-cell ASICs, and trade raw clock frequency and energy efficiency for design flexibility, parallel hardware fabric, and per-chip reconfigurability. Within Intel/Altera's hierarchy, the Stratix GX family targets high-end applications that combine parallel DSP fabric with embedded high-speed serial transceivers. Key differentiating features include 4,125 LABs/CLBs (Logic Array Blocks / Configurable Logic Blocks) versus the older 1,840 of the original Stratix family, 4 embedded PLLs, and dedicated hardware multipliers for DSP. The 1020-pin FBGA package uses a 33 x 33 mm substrate with 1.0 mm pitch, requiring a multi-layer PCB with controlled-impedance routing. Operating temperature is commercial 0C to +85C. Technical depth: the Stratix GX architecture combines a TriMatrix memory structure (MRAM blocks of various widths), an embedded row/column interconnect, and per-quadrant high-speed transceivers paired with Clock Data Recovery (CDR) logic. The 'C6' speed grade indicates a -6 commercial speed bin, and the 'N' suffix denotes a Pb-free / lead-free terminal finish. Power architecture requires multiple supply rails (VCCINT core, VCCIO bank I/O, VCCA_PLL analog, VCC_GXB transceiver) with sequencing recommendations documented in the Altera Stratix GX Handbook. Typical applications include high-speed serial interface bridging (XAUI, PCI Express endpoint, Serial RapidIO), telecom line cards with SERDES aggregation, prototype ASIC replacement, broadcast video processing, and industrial test equipment with parallel ADC/DAC data capture. Designers choose the EP1SGX40GF1020C6BN when design entry needs the embedded 3.125 Gbps transceivers plus ample logic for protocol state machines. Design consideration: verify DDR2/QDRII SRAM interface timing against the chosen speed grade, plan decoupling on every VCCIO bank, and confirm the multi-gigabit transceiver reference clock architecture before PCB layout because the 1020-BGA package cannot be reworked by hand.
