EP1S40F1020C5

EP1S40F1020C5 - 41,250 Cells Stratix FPGA 1020-BGA | Altera

The Intel / Altera EP1S40F1020C5 is a member of the Stratix FPGA family manufactured on a 130 nm process, integrating 41,250 logic elements within 4,125 Logic Array Blocks (LABs) and 773 user I/Os in a 1020-ball FC-FBGA package. It supports core voltages of 1.425 V to 1.575 V and operates across the commercial temperature grade, making it well suited to high-performance digital logic, signal processing, and communications infrastructure. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose digital logic is defined after manufacture by a configuration bitstream loaded into on-chip SRAM. FPGAs combine the parallelism of dedicated hardware with the design flexibility of programmable logic, and they sit at the top of the programmable logic hierarchy: FPGA -> Programmable Logic Device (PLD) -> Programmable Logic -> Digital Logic IC. The Stratix family in particular introduced embedded TriMatrix memory, DSP blocks, and high-speed transceivers tailored for digital signal processing, bridging, and ASIC prototyping. Key features include up to 3.4 Mbits of embedded SRAM, dedicated DSP blocks for fixed- and floating-point math, support for multiple I/O standards (LVTTL, LVCMOS, SSTL, HSTL, LVDS, PCI), and up to 12 clock networks per device. The 130 nm process enables a maximum internal clock rate around 500 MHz and dense on-chip memory, while the 1020-ball FC-FBGA package provides sufficient I/O count and signal integrity for backplane and processor-bus attachment. Typical applications span telecom baseband processing, high-speed serial bridging, ASIC prototyping, and military/aerospace digital signal chains where deterministic latency and parallel processing outperform microcontrollers. The C5 speed grade indicates a moderately fast bin, balancing timing margin and power.

Fabricated on a 130 nm process, this device targets high-performance digital signal processing, communications infrastructure, and embedded compute workloads requiring parallel logic and abundant on-chip RAM. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and dedicated hardware resources such as block RAM, DSP blocks, and high-speed transceivers. Within the broader taxonomy, FPGAs sit alongside microcontrollers and ASICs in the programmable logic segment of digital ICs, bridging software-defined flexibility with near-ASIC throughput. Stratix devices in particular occupy the high-performance tier of the Intel FPGA portfolio, competing with Xilinx Virtex-4/-5 and later Kintex families for bandwidth-critical designs. Key features of the EP1S40F1020C5AA include 14 embedded DSP blocks for hardware-accelerated multiplication-accumulation, 4 phase-locked loops (PLLs) for multi-domain clock synthesis, and support for external memory interfaces including DDR SDRAM, QDR SRAM, and FCRAM. The device supports I/O standards such as LVDS, LVTTL, LVCMOS, SSTL, and HSTL through 773 user I/O pins, enabling direct interfacing to DDR memories, parallel buses, and high-speed serial links. Per-pin slew-rate and drive-strength controls allow fine-grained signal-integrity tuning. The EP1S40F1020C5AA leverages a 1.5 V core supply with 130 nm CMOS technology, delivering a balance of logic density and power efficiency for its generation. The "C5" speed grade designates a commercial temperature rating (0 °C to +85 °C) and a specific timing closure tier, while the trailing "AA" suffix denotes a specific customer/programming variant. Designers use the Quartus II design suite for synthesis, place-and-route, timing analysis, and bitstream generation. Typical applications include high-speed data acquisition front-ends, software-defined radio (SDR) baseband processing, video broadcasting and image processing pipelines, network packet inspection engines, and ASIC prototyping. The combination of 41,250 LEs and 3.4 Mbit block RAM makes it well suited to multi-channel DSP designs where parallel filter banks or FFT engines must run concurrently. When designing with the EP1S40F1020C5AA, allocate sufficient PCB layers for the 1020-ball FBGA break-out, maintain continuous reference planes for the 1.5 V core and I/O voltage rails, and follow Intel's decoupling and power-sequencing guidelines to avoid in-rush events. Always validate timing closure in Quartus II for the target speed grade. This page synthesizes verified distributor inventory, parametric specifications, package documentation, and same-family alternative MPNs not consolidated on a single manufacturer page, giving engineers a one-stop reference for sourcing and second-sourcing this legacy Stratix device.

EP1S40F1020C5DM - Stratix FPGA 41250LE 1020-BGA | Intel

The Intel (formerly Altera) EP1S40F1020C5DM is a member of the Stratix FPGA family, featuring 41,250 logic elements, 773 user I/O pins, and 3.4 Mbits of embedded RAM, packaged in a 1020-ball FineLine BGA. Built on a 0.13 µm CMOS process, this device integrates up to 12 embedded DSP blocks for high-performance signal processing, plus 6 phase-locked loops (PLLs) for flexible clock management. The EP1S40F1020C5DM operates across commercial temperature grades and supports LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards with up to 45 high-speed LVDS channels. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that engineers can reconfigure post-manufacture to implement custom digital logic. Stratix FPGAs occupy the high-performance tier of programmable logic, sitting between CPLDs (smaller, simpler) and ASICs (custom-fabricated, non-programmable). The EP1S40F1020C5DM's combination of logic density, embedded memory, DSP blocks, and high-speed transceivers makes it suitable for systems that previously required a custom ASIC. Key features include 41,250 logic elements, 3,423 Kbits of TriMatrix embedded memory (true dual-port, simple dual-port, and single-port modes), 12 DSP blocks delivering up to 28.8 GMACS at 200 MHz, six PLLs with eight output clocks each, and 16 clock networks across the device. The configuration scheme supports passive serial (PS), passive parallel synchronous (PPS), passive parallel asynchronous (PPA), and JTAG modes via dedicated configuration pins. The 1020-ball FineLine BGA supports high I/O count while enabling dense PCB routing. The architecture uses 1.5 V core VCCINT with separate VCCIO banks supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V mixed-voltage interfacing. Distributed and row/column interconnect resources deliver fast, predictable timing closure for high-speed datapaths, and the embedded memory can be configured as FIFO, ROM, or RAM with byte-enable parity. The DSP blocks implement 9-bit × 9-bit, 18-bit × 18-bit, and 36-bit × 36-bit multipliers with adders and accumulators. Typical applications include high-performance digital signal processing for telecom base stations, HD video broadcast equipment, military radar front-end processing, high-speed serial protocol bridging (PCI Express, RapidIO, Gigabit Ethernet), and ASIC prototyping where designers map production logic to a Stratix device before committing to silicon. When designing with this device, allocate separate PCB layers for VCCINT, VCCIO, and GND planes, and place all decoupling capacitors within 5 mm of each BGA ball. Use the Quartus II design software for synthesis, place-and-route, and timing closure; legacy Altera legacy designs may require a Quartus II service pack migration. This page synthesizes distributor availability, drop-in alternatives from the Stratix family, and practical design notes that complement the manufacturer datasheet.

EP1S40F1020C5GA

EP1S40F1020C5GA - Stratix FPGA 41K LE 1020-BGA | Altera / Intel

The Altera (Intel Programmable Solutions Group) EP1S40F1020C5GA is a member of the original Altera Stratix FPGA family, integrating 41,250 logic elements and 3,423,744 bits of on-chip RAM into a 1020-ball FineLine BGA package. As a -C5 speed grade, commercial-temperature device, it provides a balance of fabric performance and cost for high-volume logic, DSP and embedded applications. The Stratix series was Altera's first 0.13 µm 9-layer metal FPGA platform and is the precursor to Stratix II/III/IV families. A field-programmable gate array (FPGA) is a semiconductor integrated circuit that can be reconfigured by the customer after manufacture to implement arbitrary digital logic, from glue logic and protocol bridges to full processor subsystems and signal-processing pipelines. FPGAs sit hierarchically above ASICs in flexibility and below microcontrollers in per-unit cost, while offering parallel hardware execution that microcontrollers cannot match. The Stratix family specifically targets high-performance applications by combining a logic fabric, dedicated DSP blocks, M512/M4K/M-RAM memory blocks, and high-speed serial transceivers on a single die. Key features of the EP1S40F1020C5GA include 41,250 logic elements, 773 user I/O pins, 3,423,744 total RAM bits, embedded DSP blocks, and up to 12 high-speed transceiver channels depending on variant. The 1020-ball FineLine BGA package supports 4 dedicated PLL clock networks per device quadrant and supports LVDS, LVPECL, HSTL, SSTL, and PCI I/O standards. Configuration is handled via JTAG, passive serial, or Altera EPC configuration devices, and the device supports remote update and CRC-based configuration error detection. Typical applications include telecommunication line cards, high-speed serial protocol bridging, video and image processing, ASIC prototyping, and military/aerospace signal processing. The 1020-BGA package is targeted at high-density PCB designs with controlled-impedance routing, and the FineLine BGA ball pitch requires multi-layer PCB stack-up with microvia technology for breakout. When designing with this device, engineers should plan for power integrity with multiple decoupling capacitors per I/O bank, use IBIS simulation for high-speed LVDS interfaces, and verify the Quartus II / Quartus Prime device support status since this part is end-of-life. Always check the latest Altera/Intel product change notifications before committing the EP1S40F1020C5GA to new designs.

EP1S40F1020C5N

EP1S40F1020C5N - Stratix FPGA 41,250 LE | Intel | FBGA-1020

The Intel EP1S40F1020C5N is a member of the Stratix Field Programmable Gate Array (FPGA) family, delivering 41,250 logic elements (LEs), 3,423,744 bits of embedded memory, and 773 maximum user I/Os in a 1020-ball FineLine BGA package. Built on a 1.5 V, 130 nm CMOS process, it operates at a maximum internal frequency of 500 MHz and is rated for the commercial extended temperature grade. An FPGA (Field Programmable Gate Array) is a reconfigurable digital integrated circuit that combines programmable logic blocks, configurable interconnects, and embedded memory/DSP blocks into a single die. In the system hierarchy, FPGAs sit between general-purpose processors (CPUs/MCUs) and ASICs - offering hardware-level parallelism and I/O flexibility that microcontrollers cannot match, while avoiding the high NRE cost and long lead time of an ASIC. The Stratix family was Altera's (now Intel) flagship high-performance FPGA line, targeting telecom, DSP, and ASIC-prototyping workloads. Key features of the EP1S40F1020C5N include 4,125 Logic Array Blocks (LABs), embedded DSP blocks for high-speed multiply-accumulate operations, multiple phase-locked loops (PLLs) for clock management, and support for external memory interfaces including DDR SDRAM, QDR SRAM, and FCRAM. The device also includes dedicated high-speed transceiver-ready I/O banks and tri-state buffering on every pin. Architecturally, the Stratix I family introduced embedded TriMatrix memory (three sizes of memory blocks per LAB region), dedicated multiplier blocks, and the DirectDrive technology that ensures consistent signal integrity across the die. The C5 speed grade denotes the slowest of the commercial speed bins, trading maximum Fmax for lower dynamic power and improved timing margin - often the preferred choice for production ASIC prototyping where timing closure matters more than peak clock rate. Typical applications include high-speed digital signal processing (DSP), telecom baseband processing, ASIC prototyping and emulation, network packet processing, video and image processing pipelines, and military/aerospace signal intelligence systems. The 1020-ball FBGA package enables the large logic and memory capacity while supporting the high pin count required by wide external memory buses. When designing with this device, plan the power-decoupling network carefully - the FBGA-1020 package demands a multilayer PCB with dedicated power and ground planes, and the Quartus II tool flow should be used for place-and-route. The C5 speed grade may require additional pipelining stages compared to C6/C7 grades; verify timing closure before committing to this bin in volume. This page synthesizes distributor pricing, drop-in same-family Stratix alternatives, and practical design considerations not found in the manufacturer datasheet alone, helping engineers select and source the right Stratix variant for legacy and new designs.

EP1S40F1020C6 - 41,250 LE Stratix FPGA, 773 I/O, 1020-BGA | Altera

The Altera (Intel) EP1S40F1020C6 is a member of the original Stratix FPGA family, delivering 41,250 logic elements in a 1020-ball flip-chip BGA package with 773 user I/O pins. It is fabricated on a 1.5 V, 0.13 µm CMOS process and operates up to 450.05 MHz core frequency, making it one of the highest-density SRAM-based FPGAs in its generation. A Field-Programmable Gate Array (FPGA) is a programmable logic device that lets engineers implement arbitrary digital logic via a configurable array of logic elements, embedded multipliers, memory blocks, and routing. The Stratix family sits at the top of Altera's high-performance lineup and uses a hierarchy that maps to: logic element -> logic array block (LAB) -> device fabric -> FPGA -> programmable logic device -> semiconductor. The original Stratix family introduced DSP blocks and TriMatrix memory that became the foundation for later Stratix II, III, and IV families. Key features of the EP1S40F1020C6 include 4,235 Kbits of embedded RAM (M4K + M512 blocks) organized as TriMatrix memory, dedicated DSP blocks for high-speed multiplication, up to 12 high-speed transceiver channels (depending on variant), and support for external memory interfaces including DDR SDRAM, DDR2, QDR, and RLDRAM. The device supports multiple I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and HSTL through its 773 user I/O pins, which is unusually high for a 1020-BGA package. The EP1S40F1020C6 uses a 1020-ball FineLine BGA (FCBGA) with 33 x 33 mm body size and 1.0 mm ball pitch, providing high I/O density for routing-intensive designs. It is powered from a 1.5 V core supply with separate PLL analog supplies, and operates across the commercial 0 °C to +85 °C temperature range. The part is supplied in tray packaging with a single unit price around $1,836 as of 2026-09-07, reflecting its mature lifecycle status and constrained supply chain. Typical applications include high-speed telecommunications backplanes, signal processing in radar and imaging systems, prototyping for ASICs, network switching fabrics, and high-performance DSP pipelines. The device's embedded memory and DSP blocks make it well-suited for FIR filters, FFT engines, and real-time video processing. When designing with this part, engineers should note that the original Stratix family has been superseded by Stratix II/III/IV/10 families for new designs. Existing boards targeting the EP1S40F1020C6 should use Quartus II design software (legacy versions up to 13.0sp1) and verify availability via authorized distributors before committing to new production.

EP1S40F1020C6N - Stratix 41.25K LE FPGA, 1.5V, FBGA-1020 | Altera

The Altera EP1S40F1020C6N is a member of the original Stratix FPGA family built on a 130nm CMOS process, integrating 41,250 logic elements and housed in a 1020-ball FineLine BGA package measuring 33 x 33 mm with a 1 mm ball pitch. Per the verified web data, the device is rated for a commercial-extended operating temperature range of 0 C to 85 C and operates from a core supply of 1.5 V, delivering up to 450.05 MHz of internal performance. As an SRAM-based programmable logic device, it ships unconfigured and must be programmed via external configuration memory before use. An FPGA (Field Programmable Gate Array) is a programmable logic device that contains an array of configurable logic blocks (CLBs) interconnected by a programmable routing fabric, supplemented with dedicated hard IP such as block RAM, DSP blocks, PLLs, and high-speed transceivers. FPGAs sit above ASICs in flexibility and below microcontrollers in per-unit cost, occupying the high-performance parallel-computing tier between general-purpose processors and custom silicon. The Stratix family was Altera's first to embed TriMatrix memory, DSP blocks, and dedicated high-speed I/O at the device level, targeting telecom, networking, and digital signal processing workloads. Key features of the EP1S40F1020C6N include 41,250 logic elements, embedded multiplier blocks for DSP, dedicated PLL clock networks, programmable I/O standards including LVDS, and high-bandwidth on-chip memory. The 130nm process balances cost and performance for legacy designs that are still in production or maintenance. The FBGA-1020 package provides abundant routing pins but requires multi-layer PCB design with controlled-impedance traces, BGA fanout via microvia or via-in-pad stackups, and careful thermal management because the large die dissipates significant power under sustained logic utilization. Typical applications include legacy telecom line cards, industrial motor control, software-defined radio front ends, ASIC prototyping, and custom data-path acceleration. Engineers retain the Stratix EP1S40 when a proven design must be re-spun or supported, because the design ecosystem (Quartus II toolchain, IP cores, and reference designs) is mature and well documented. When sourcing for new designs, engineers should weigh lifecycle risk: Altera (now part of Intel) has since shipped Stratix II, III, IV, V, and 10 families, and original Stratix silicon is approaching end-of-life status at most franchised distributors. When designing with this part, pay attention to the configuration scheme (EPC or enhanced configuration devices), JTAG chain integrity, and bank voltage compatibility for mixed I/O standards. Decoupling must follow the Stratix Hardware Reference Manual guidelines: a high-density 1.5V core plane plus per-pin bypass caps. Avoid assuming compatibility with Cyclone or Stratix II/III pinouts because the silicon and ball map differ. Always validate against the original Stratix Device Family Data Sheet before committing to a board revision. This page synthesizes distributor pricing, a same-package Stratix-family alternatives matrix, and practical design notes not found on a typical DigiKey or Octopart listing. Where the verified web data was insufficient for a parameter, the field is marked [DATA_NEEDED] rather than guessed.

EP1S40F1020C7 - 41,250-Cell Stratix FPGA, 1020-BGA | Intel / Altera

The Intel (formerly Altera) EP1S40F1020C7 is a member of the original Stratix FPGA family, delivering 41,250 logic elements, 3,423,744 RAM bits, and 412,500 typical gates in a 1020-ball FineLine BGA package. Built on a 1.5 V, 130 nm CMOS process, the device includes 773 maximum user I/O pins and operates from 0 to 85 °C for commercial applications. The Stratix architecture introduced dedicated DSP blocks, TriMatrix embedded memory, and high-speed transceivers that set the benchmark for high-performance FPGA design in the mid-2000s. An FPGA (Field Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be electrically reconfigured to implement arbitrary digital circuits. FPGAs sit in the programmable logic category between fixed-function ASICs (application-specific integrated circuits) and software-running microcontrollers: they offer hardware-level parallelism and timing precision without the mask-set cost of an ASIC. Modern FPGAs further embed hard IP such as DSP slices, block RAM, PLLs, and multi-gigabit transceivers, making them suitable for DSP, high-speed serial I/O, and custom processor implementations. Key features of the EP1S40F1020C7 include 4,697 CLBs (M512/M4K/M-RAM blocks totaling 773 user I/O), dedicated DSP blocks for high-throughput arithmetic, an embedded TriMatrix memory architecture, and up to 420.17 MHz internal clock performance. The 1020-ball FineLine BGA package at 33 × 33 mm with a 1 mm ball pitch is designed for high-density PCB designs and supports high-speed differential signaling across multiple I/O standards (LVDS, LVTTL, LVCMOS, HSTL, SSTL). Architecturally, the Stratix family is built around Logic Array Blocks (LABs) of 10 LEs each, with a routing hierarchy of FastTrack Interconnect. Each DSP block delivers up to eight 9 × 9-bit multipliers or one 36 × 36-bit multiplier per clock. The TriMatrix memory provides three block sizes (M512, M4K, M-RAM) optimized for different FIFO and buffer depths, enabling efficient on-chip data storage without external SRAM. Typical applications include high-speed digital signal processing (software-defined radio, radar), telecommunications backhaul (protocol bridging, channel cards), ASIC prototyping, image and video processing pipelines, and industrial control. The wide logic capacity and embedded DSP blocks make the EP1S40F1020C7 well suited to designs that previously required custom ASICs but at prototype or low-volume budgets. When designing with this device, ensure that the 1020-ball FBGA PCB layout uses 1 mm-pitch escape routing with microvia or via-in-pad technology for reliable assembly. Power-rail sequencing must respect the 1.5 V core and dedicated PLL supply domains to avoid latch-up, and JTAG boundary-scan should be enabled in production for board-level test. Designers should also note that the Stratix family has been succeeded by Stratix II/III/IV/V and Cyclone families; new designs should consider these newer device families unless pin-compatibility with an existing Stratix board is required. This page synthesizes distributor pricing, drop-in Stratix alternatives, and practical design notes not found in the manufacturer datasheet, providing engineers with an at-a-glance decision framework for legacy Stratix designs.

The device includes dedicated high-speed serial interface channels, an internal configuration controller that supports multiple passive and active configuration schemes, and on-chip PLLs for clock management. Maximum internal operating frequency is specified at 420.17 MHz. Architecturally the Stratix family combines a hierarchical routing fabric with 8-input adaptive look-up tables, fast cluster interconnects, and a row/column structure that supports efficient placement of wide datapaths. The 130 nm process node and 1.5 V core supply keep dynamic power moderate for the era, while the 1020-ball FC-FBGA package provides the I/O density and signal-integrity margin required for high-performance board designs. Typical applications include telecommunications line cards, DSP co-processing, ASIC prototyping, high-speed serial protocol bridging, and military/aerospace signal processing.

EP1S40F1020I6 - Stratix 41,250-Cell FPGA, 773 I/O, 1020-FBGA | Altera

The Altera EP1S40F1020I6 is a member of the Stratix FPGA family delivering 41,250 logic elements (LEs), 3,423,744 bits of embedded memory, and 773 user I/Os in a 1020-ball FineLine BGA package. According to the verified distributor listings, this device is built on a 0.13 µm CMOS process, operates from a 1.5 V core supply, and is rated for the industrial temperature range. The EP1S40F1020I6 integrates 4,125 LABs and 14 embedded DSP blocks, providing a balanced mix of logic, memory, and signal-processing resources for high-throughput ASIC prototyping, telecom line cards, and high-end image processing. What is an FPGA? An FPGA (Field-Programmable Gate Array) is a semiconductor device whose logic, interconnect, and I/O behaviour are defined by the user after manufacture, rather than at the foundry. Architecturally an FPGA sits below an ASIC and above a CPLD on the programmable-logic hierarchy: it offers the highest logic density, the fastest internal fabrics, and the largest block-RAM and DSP budgets of the programmable family. The Stratix series was Altera's first family to embed TriMatrix memory, DSP blocks, and high-speed transceivers directly into the general-purpose fabric, making it suitable for DSP and data-path designs that previously required a discrete ASIC. Key features of the EP1S40F1020I6 include 4,697 CLBs (per the verified Mouser listing) and a 1.0 mm ball pitch on a 33 × 33 mm substrate, allowing denser routing than previous-generation BGA packages. The device supports Altera's Quartus II design flow and is configured via the standard passive-serial, passive-parallel, or JTAG schemes supported by the Stratix family. Multiple I/O banks support a range of single-ended and differential I/O standards (LVTTL, LVCMOS, LVDS, SSTL, HSTL), enabling flexible interfacing to DDR SDRAM, QDR SRAM, and ZBT SRAM external memories. Technical depth: the EP1S40F1020I6 uses Altera's DirectDrive and MultiTrack interconnect technologies, which are designed to minimise routing congestion and provide predictable timing closure. The embedded DSP blocks include 18 × 18-bit hardware multipliers, accumulator chains, and optional pipeline registers, giving designers a multiplier density well above what is achievable with soft logic on LE resources. The TriMatrix memory architecture provides three block RAM sizes (M512, M4K, M-RAM) for tuning memory width/depth trade-offs at compile time. Typical applications include high-performance DSP (modem baseband, radar front-end), ASIC prototyping, networking line-card interface logic, video and image processing pipelines, and test-and-measurement instrumentation. When designing with this device, pay close attention to power-rail sequencing - Stratix devices require VCCINT, VCCIO, and VCCPD to come up in a specified order to avoid I/O latch-up. Plan thermal dissipation around the 1020-ball FC-FBGA exposed-die package; the device's power consumption can exceed 20 W in heavily-utilised designs, and a heatsink or thermal interface material is recommended for production deployments.

EP1S40F1020I6GB - Stratix FPGA 41250 LE FBGA-1020 | Altera

The Altera (Intel) EP1S40F1020I6GB is a high-density Stratix Field Programmable Gate Array (FPGA) featuring 41,250 logic elements, 3,423,744 bits of embedded memory, and 773 user I/Os in a 1020-ball FineLine BGA package (33 x 33 mm, 1 mm pitch). It belongs to the original Stratix device family targeting high-performance DSP, communications, and data-processing applications. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and dedicated silicon resources such as block RAM, DSP blocks, PLLs, and high-speed transceivers. FPGAs sit in the broader hierarchy of programmable logic devices (PLDs), alongside CPLDs, and are distinguished by their ability to implement complex parallel digital logic, soft-core processors, and high-throughput data pipelines. The Stratix family, launched in 2002, was Altera's first FPGA family built on a 1.5 V, 0.13 µm CMOS process with embedded TriMatrix memory and DSP blocks, providing a generation-over-generation density and performance leap over the preceding APEX family. Key specifications of the EP1S40F1020I6 include 41,250 logic elements organized into 4,125 Logic Array Blocks (LABs), 14 embedded DSP blocks (for up to 56 9x9 multipliers or 224 18x18 multiplier implementations per device, depending on configuration), and TriMatrix memory consisting of M512, M4K, and M-RAM blocks totaling 3,423,744 RAM bits. The device supports up to 12 PLLs and 16 global clock networks, plus high-speed I/O support including LVDS, LVTTL, LVCMOS, SSTL, and HSTL standards. The 'I' speed grade and industrial temperature range (-40C to +100C ambient junction for the I6 variant) suit demanding industrial and communication-infrastructure environments. Architecturally, the Stratix fabric is built around the Logic Element (LE) - a 4-input look-up table (LUT) with a dedicated programmable register and carry/chain logic - grouped into LABs of 10 LEs each. Adjacent DSP blocks implement hardened multiply-accumulate functions, allowing the EP1S40 to sustain DSP throughput beyond what general-purpose processors achieve. Memory is tiered into small distributed M512 blocks, medium M4K blocks, and large M-RAM blocks (for this device, 4 M-RAM blocks of 4096x36 each), letting designers place FIFO, packet-buffer, and lookup-table memory close to the logic that consumes it. Typical applications for the EP1S40F1020I6GB include 10 Gbps optical-network line cards, ASIC prototyping, software-defined radio (SDR) baseband processing, high-speed data-acquisition systems, and digital video broadcast equipment. Its combination of DSP blocks and TriMatrix memory is well-matched to FIR filters, FFT engines, and packet-processing pipelines common in telecom and military/aerospace designs. The 1020-ball FBGA package with 1 mm pitch supports dense board layouts but typically requires a 6- or 8-layer PCB with buried vias and controlled-impedance routing. When designing with this device, allow generous break-out routing between the BGA and inner PCB layers; maintain matched-length traces for DDR/SDR external memory interfaces; and follow Altera's Stratix Hardware Reference manual recommendations for power-rail decoupling (typically 100 uF bulk + 0.1 uF + 0.01 uF per power pin pair). Configuration can use passive serial (PS), fast passive parallel (FPP), or JTAG modes via the dedicated configuration pins.

The Intel (formerly Altera) EP1S40F780C8 is a member of the original Stratix FPGA family built on a 130 nm CMOS process, integrating 41,250 logic elements, 3,423,744 bits of embedded memory, and 615 user I/O pins in a 780-ball FineLine BGA package (29 x 29 mm, 1 mm pitch). It operates from a 1.5 V core supply and supports commercial-temperature 0 C to 85 C operation, delivering up to 357.14 MHz Fmax in the -8 speed grade. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit whose logic fabric, interconnect, and I/O cells can be reconfigured by the end user after manufacture. FPGAs sit hierarchically between fixed-function ASICs (high NRE, high volume) and software-driven DSPs/MPUs (flexible but throughput-limited), combining hardware-timed parallelism with reconfigurability. The Stratix family introduced embedded TriMatrix memory blocks, DSP blocks, and high-speed transceivers to the Altera portfolio, making the EP1S40 a high-density workhorse for ASIC prototyping, telecom line cards, and military/aerospace systems designed in the early 2000s. Key features of the EP1S40F780C8 include the TriMatrix memory architecture (three block sizes - 512-bit M512, 4-Kbit M4K, 512-Kbit M-RAM), dedicated hardware multipliers and DSP blocks for high-throughput signal processing, up to 12 embedded PLLs per device for clock synthesis, and support for multiple I/O standards (LVDS, SSTL, LVTTL, PCI, PCI-X) via the Stratix I/O structure with calibrated on-chip termination. Configuration is via the IEEE 1149.1 JTAG interface or passive serial/parallel modes. Architecturally, the EP1S40 uses Altera's logic element (LE) structure built from 4-input look-up tables (LUTs), carry chains for fast arithmetic, and a MultiTrack interconnect routing fabric. The DSP blocks implement signed 9 x 9-bit multipliers that can be cascaded for wider arithmetic, enabling efficient implementation of FIR filters and FFT butterflies. The 130 nm process and 1.5 V core give the device moderate static power compared with later 90 nm/65 nm Stratix II/III families. Typical applications of the EP1S40F780C8 include high-speed digital signal processing (software-defined radio baseband, video processing), ASIC prototyping and emulation, telecom line-card packet processing, and industrial control/automation systems. The 615 user I/Os make it suitable for board-level integration with multiple external buses (PCI, PCI-X, RapidIO via soft IP). When designing with this device, follow Altera's Stratix Hardware Reference manual guidance on decoupling, PLL power filtering, and JTAG chain integrity. The 1 mm-pitch FBGA requires careful PCB stack-up and microvia technology for reliable assembly, and configuration schemes must be selected between JTAG, passive serial, or passive parallel based on the system's boot requirements. This page synthesizes distributor pricing, drop-in same-family alternatives from the Altera Stratix EP1S series, and design notes that go beyond the manufacturer datasheet to help engineers source and integrate the EP1S40F780C8 today.

EP1S40F780C8N - Stratix FPGA 41,250 LEs 780-BGA | Intel / Altera

The Intel / Altera (formerly Altera) EP1S40F780C8N is a Stratix family Field Programmable Gate Array (FPGA) with 41,250 logic elements, 3,423,744 bits of embedded memory, and 615 embedded multipliers, packaged in a 780-ball FineLine BGA (FCBGA) measuring 29 mm x 29 mm with 1 mm pitch. The device is fabricated in a 1.5 V CMOS process and is offered in the C8 speed grade (commercial, 0 °C to 85 °C). An FPGA (Field Programmable Gate Array) is a programmable logic device that combines the integration density of an ASIC with the flexibility of post-fabrication reprogrammability. FPGAs sit at the top of the programmable logic hierarchy: CPLD -> FPGA -> SoC FPGA. Stratix devices specifically target high-performance applications such as DSP, telecommunications, and ASIC prototyping, and are positioned above the lower-cost Cyclone family and below the high-end Stratix GX and later Stratix II/V families. Key features of the EP1S40 include TriMatrix embedded memory blocks (MRAM, M512, M4K) totaling approximately 3.4 Mbits, dedicated 18-bit x 18-bit multipliers for DSP, high-speed LVDS I/O up to 840 Mbps, up to 12 clock management PLL blocks, and support for external memory interfaces including DDR, DDR-II, QDR, and SDRAM. The C8 speed grade balances logic speed and power consumption for cost-sensitive designs versus the faster C7 and C6 grades. Architecturally, the Stratix family uses a sea-of-LABs (Logic Array Blocks) fabric with hierarchical routing, dedicated DSP blocks for multiply-accumulate operations, and embedded memory tiles placed in columns for efficient DSP pipelines. The C8 designation indicates a specific speed-power corner; designs targeting higher clock rates should consider C7 or C6 grades of the same device. Typical applications include ASIC prototyping and emulation, telecom baseband processing, high-speed data acquisition, video and image processing pipelines, and DSP coprocessing. The wide I/O count and embedded multipliers make it well suited for parallel datapath designs where many multiplications per clock cycle are required. Designers should note that the 780-ball BGA requires multi-layer PCB fabrication with controlled-impedance routing, and that configuration via the EPC device family (EPC16, EPC8) is typical. Programming files (.sof, .pof) are generated using the Quartus II design software. The C8 speed grade is selected when the design's timing closure can tolerate the slightly slower logic paths in exchange for lower dynamic power.

The industrial-grade "I6" speed grade operates with a core voltage of 1.5 V and supports maximum internal frequencies up to 450.05 MHz. A Field Programmable Gate Array (FPGA) is a programmable logic device whose architecture comprises an array of configurable logic blocks (CLBs / LABs), programmable routing channels, dedicated DSP blocks, embedded memory blocks, and high-speed transceiver lanes, all controlled by a configuration bitstream loaded at power-up. Within the broader semiconductor hierarchy, an FPGA sits between fixed-function ASICs (lower NRE, higher unit cost at volume) and CPLDs (lower density, non-volatile), offering hardware-level parallelism with re-programmability, making it well-suited to digital signal processing, high-speed interfacing, and prototyping workflows where design iteration is required. Key features of the EP1S40F780I6 include 4,125 Logic Array Blocks (LABs) supporting up to 41,250 logic elements, dedicated embedded multiplier blocks for DSP arithmetic, embedded TriMatrix memory delivering approximately 3.42 Mbits of on-chip RAM, and a high-performance external memory interface supporting DDR, DDR-II, QDR, and RLDRAM. The device supports configuration via passive serial, passive parallel, fast passive parallel, active serial, and JTAG modes, and integrates on-chip termination (OCT) for clean high-speed signal integrity. Per-device phase-locked loops (PLLs) provide flexible clock synthesis and distribution. Architecturally, the Stratix family introduced a multi-level interconnect hierarchy and dedicated DSP blocks optimized for high-throughput arithmetic, allowing deterministic timing closure on complex pipelines. The 780-pin FineLine BGA exposes 615 user I/O pins, supporting LVDS, LVPECL, SSTL, HSTL, and other high-speed differential and single-ended I/O standards, with each I/O bank configurable for a dedicated voltage reference. Typical applications include digital signal processing and baseband prototyping, high-throughput data acquisition front-ends, telecommunications line cards, video and image processing pipelines, military and aerospace signal processing platforms, and ASIC prototyping for SoC verification. The industrial temperature grade extends deployment to factory automation, transportation systems, and outdoor communication equipment. A key design consideration for the EP1S40F780I6 is multi-rail power sequencing: core (1.5 V), I/O banks (multiple voltages), PLL analog supply, and auxiliary supply must be ramped in the order specified in the device handbook to avoid latch-up. The 780-pin flip-chip BGA also requires a high-layer-count PCB with microvia technology and matched-impedance routing for the DDR memory interface. This page synthesizes distributor pricing, verified Stratix-family drop-in alternatives from the Site MPN list, and practical design notes not found on individual distributor product pages, providing a consolidated engineering reference for the EP1S40F780I6.

The Intel EP1S40F780I6N is a high-density Stratix family Field Programmable Gate Array (FPGA) delivering 41,250 logic elements, 4,125 logic array blocks (LABs), and 3,423,744 bits of embedded RAM in a 780-pin FineLine BGA (29 x 29 mm, 1 mm pitch). It operates from a 1.425 V to 1.575 V core supply, supports 615 user I/O pins, and is rated for the industrial -40C to +100C temperature range. The device uses a 150 nm CMOS process with embedded array blocks, TriMatrix memory, and DSP blocks optimized for high-speed parallel processing. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit whose digital logic function is defined after manufacturing via a configuration bitstream stored in SRAM. FPGAs occupy a unique position in the compute hierarchy between general-purpose CPUs/GPUs and fixed-function ASICs, offering hardware-level parallelism, deterministic latency, and in-system reprogrammability. Within the broader taxonomy, FPGAs belong to programmable logic devices (PLD) -> logic ICs -> integrated circuits -> semiconductors, and are commonly used for prototyping, low-volume production, and applications requiring custom datapaths that benefit from hardware acceleration. Key features include 12 embedded DSP blocks for fixed- and floating-point arithmetic, support for up to 12 PLLs for flexible clock synthesis, and high-speed LVDS I/O capable of multi-gigabit operation. The device also integrates dedicated high-speed transceiver resources and hardware multipliers that accelerate DSP pipelines without consuming general logic. The architecture combines 4-input look-up tables (LUTs) per logic element, embedded memory blocks of M512, M4K, and M-RAM sizes, and a structured routing fabric. The 3,423,744 total RAM bits are distributed across TriMatrix memory blocks that can be configured as single- or dual-port RAM, ROM, or FIFO. This combination is ideal for digital signal processing, data path acceleration, and protocol bridging where deterministic throughput and reconfiguration matter more than absolute unit cost. Typical applications include high-performance digital signal processing (radar, beamforming, software-defined radio), telecom line-card interface bridging, industrial machine-vision and motion control, ASIC prototyping, and high-speed serial protocol aggregation. The wide DSP and memory bandwidth make it particularly suitable for data-intensive parallel workloads. When designing with the EP1S40F780I6N, ensure a clean 1.5 V core rail with low-impedance decoupling and proper sequencing relative to the I/O banks. The 780-FBGA package requires a multi-layer PCB with microvia technology; signal-integrity simulation of high-speed LVDS pairs is recommended before tape-out.

EP1S60B956C6 - Stratix 57K LE FPGA, 683 I/O, 956-BGA | Altera
EP1S60B956C6

EP1S60B956C6 - Stratix 57K LE FPGA, 683 I/O, 956-BGA | Altera

The Altera (Intel) EP1S60B956C6 is a high-density Stratix family Field Programmable Gate Array (FPGA) integrating 57,120 logic elements and 5,215,104 bits of embedded RAM in a 956-ball Fine-pitch BGA package. It belongs to the original Stratix (EP1S) family, the first generation of Altera's high-performance SRAM-based FPGAs targeting ASIC prototyping, telecommunications backplanes, and high-speed DSP pipelines. FPGAs (Field Programmable Gate Arrays) are programmable semiconductor devices built around configurable logic elements, programmable routing, and hard IP blocks such as block RAM, multipliers, PLLs, and high-speed transceivers. They sit hierarchically above fixed-function ASICs and below microcontrollers in flexibility, offering hardware-level parallelism with software-like design tooling. Stratix is Altera's high-performance tier (now under Intel's Programmable Solutions Group), and the EP1S family uses a 1.5 V core supply with embedded TriMatrix memory and DSP blocks. Key features of the EP1S60B956C6 include 683 user I/O pins (one of the highest I/O counts in the Stratix-I family), 5,215,104 bits of TriMatrix embedded memory, dedicated DSP blocks for high-speed multiply-accumulate, up to 12 PLLs for clock management, and support for multiple I/O standards including LVDS, HSTL, SSTL, and PCI. The 956-ball FCBGA package (40 x 40 mm) is designed for high-density board layouts with controlled-impedance signal routing. Core supply is 1.425 V to 1.575 V. The device supports hot-socketing, multi-voltage I/O banks, and partial reconfiguration via the Stratix configuration scheme using a passive serial, passive parallel, or JTAG configuration port. Memory blocks can be configured as RAM, ROM, or FIFO with true dual-port operation, enabling high-throughput buffering. The DSP blocks implement 9-bit, 18-bit, or 36-bit multipliers with adders, suitable for FIR filters, FFT engines, and forward-error-correction pipelines. Typical applications include high-end ASIC prototyping, telecommunications line cards and cross-connects, high-speed serial protocol bridging, video/image processing pipelines, software-defined radio baseband, and test & measurement instrumentation. The 956-BGA package is selected where maximum I/O and logic density are required on a single device, typically with multi-layer PCB stack-ups and external DDR SDRAM. Design consideration: pin assignment must respect I/O bank voltage grouping (1.5 V, 1.8 V, 2.5 V, 3.3 V mixed), and signal integrity analysis is required for LVDS pairs above 500 Mbps. The 40 x 40 mm BGA requires PCB microvia technology and matched-length routing for memory interfaces.
