EP1S30F780C7 - Stratix 32K LE FPGA, 780-FBGA | Altera / Intel
The Altera (now Intel) EP1S30F780C7 is a member of the original Stratix FPGA family, integrating 32,470 logic elements, 597 user I/O pins, and dedicated DSP and memory blocks into a 780-ball fine-pitch BGA package. It is fabricated on a 1.5 V core, 0.13 µm CMOS process and supports up to 3,317,184 bits of embedded SRAM organized in TriMatrix memory blocks. A Field-Programmable Gate Array (FPGA) is a programmable logic device whose logic, routing, and I/O behavior are defined by configuration SRAM. FPGAs occupy the position of ASIC prototyping, hardware acceleration, and reconfigurable computing in the broader digital IC hierarchy: programmable logic -> logic IC -> integrated circuit -> semiconductor. Stratix-class FPGAs specifically target high-performance DSP and telecommunications signal chains. Key features include 3,240 Kbits of embedded memory, dedicated DSP blocks supporting up to 224 18x18 multipliers, 12 transceiver channels (Rocket I/O) at up to 3.125 Gbps, and support for external DDR SDRAM and QDR II SRAM memory interfaces. The device also integrates a high-speed LVDS interface and a hard PCI-X core for direct bus connectivity in communication equipment. Architecturally, the EP1S30F780C7 uses a logic-array-block (LAB) structure with each LAB containing 10 logic elements (LEs). Configuration is stored in SRAM, allowing in-system reprogrammability through JTAG or passive/active serial schemes. The 780-pin FCBGA package provides 597 usable I/O pins, organized into banks supporting multiple I/O standards including LVTTL, LVCMOS, SSTL, HSTL, LVPECL, and LVDS. Typical applications include wired and wireless telecom baseband processing, high-speed serial interface bridging (XAUI, Fibre Channel, SONET), video and imaging pipelines, and ASIC prototyping for DSP and communications algorithms. The combination of dedicated multipliers and high-bandwidth memory makes this device especially well suited for OFDM and FFT-based designs. Designers should pay close attention to power-supply sequencing, decoupling, and the 1 mm pitch BGA layout (29x29 mm body). Because configuration SRAM is volatile, an external configuration PROM such as an EPC16 or EPCS device is required for stand-alone boot. Static supply currents should be evaluated against the Stratix handbook power estimator spreadsheet. This page synthesizes distributor pricing, drop-in equivalents from the same Stratix family, and practical board-design guidance not collected in any single datasheet — giving procurement and engineering teams one trustworthy decision point for this legacy but still-quotable device.
EP1S30F780C7AA - Stratix 32K LE FPGA, 597 I/O, 780-FBGA | Intel
The Intel EP1S30F780C7AA is a member of the original Stratix FPGA family, delivering 32,470 logic elements, 3,317,184 bits of embedded memory, and 597 user I/O in a 780-ball FineLine BGA package with a -7 speed grade. It is built on a 0.13 µm SRAM-based process and integrates dedicated DSP blocks, TriMatrix memory, and high-speed serial transceiver support, making it suitable for high-performance digital signal processing, telecommunications infrastructure, and data acquisition systems. An FPGA (Field-Programmable Gate Array) is a programmable logic device that lets designers implement arbitrary digital circuits after PCB fabrication. Within the broader semiconductor taxonomy, FPGAs sit between ASICs and general-purpose processors: more flexible than fixed-function ASICs yet offering deterministic hardware-level parallelism that microcontrollers cannot match. The Stratix family occupies Intel's (formerly Altera's) high-performance tier, above Cyclone and Arria in logic density and transceiver capability, and below Agilex in process node and DSP throughput. The EP1S30 specifically targets mid-density applications where designers need rich logic, embedded multipliers, and flexible I/O without paying for the largest Stratix devices like EP1S80. Key electrical and packaging attributes include 597 maximum user I/O pins, 1.5 V core voltage with multi-voltage I/O support (LVTTL, LVCMOS, LVDS, LVPECL, PCI, PCI-X), embedded DSP blocks delivering up to 2.1 GMACS at -7 speed grade, and TriMatrix memory totaling approximately 3.3 Mbits. The device is offered in a 780-ball FCBGA with a 29x29 mm or similar footprint and is specified for the commercial 0°C to +85°C operating range. Power is supplied through dedicated VCCINT, VCCIO banks, VCCA_PLL, and VCCPD pins with extensive decoupling guidance in the Stratix Device Handbook. Architecturally, the EP1S30 uses logic array blocks (LABs), each containing ten logic elements (LEs), interconnected by a multi-tiered routing fabric. Embedded multiplier blocks support 9x9, 18x18, and 36x36 signed/unsigned multiplication in a single cycle, enabling DSP-heavy designs without consuming general-purpose logic. The PLLs provide clock synthesis and skew management across up to 16 dedicated clock pins. Configuration is supported through passive serial, fast passive parallel, and JTAG modes, with optional EPC16 or EPCS serial configuration devices from Intel. Typical applications include high-end telecommunications line cards, radar and beam-forming front-ends, medical imaging pre-processors, broadcast video processing, ASIC prototyping, and military/aerospace signal processing. The combination of 597 I/O and approximately 3.3 Mbits of embedded memory makes it a flexible platform for system-on-chip prototyping where designers need to validate complex IP blocks before committing to a mask-programmed ASIC. When designing with the EP1S30F780C7AA, pay close attention to the Stratix Device Handbook pin connection guidelines: each VCCIO bank must be decoupled with 0.1 µF and 0.01 µF capacitors placed close to the balls, unused I/O must be tri-stated and tied to a defined logic level, and JTAG TCK should be pulled to a known state to avoid inadvertent boundary-scan events. Thermal management is generally passive for commercial-temperature designs but requires attention if I/O switching activity is high.

Housed in a 780-ball FC-FBGA package measuring 29 x 29 mm with 1 mm pitch, this industrial-temperature-grade device operates at a core voltage of 1.5 V. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement arbitrary digital logic. FPGAs sit at the top of the programmable-logic hierarchy: FPGA -> CPLD -> programmable logic -> digital IC -> semiconductor. They are distinguished from Application-Specific Integrated Circuits (ASICs) by re-programmability and from CPLDs by their greater logic density, embedded RAM blocks, DSP blocks, and high-speed transceiver support. The Stratix family in particular was Altera's first generation to embed TriMatrix memory blocks, DSP blocks, and high-speed I/O structures optimized for parallel processing and communications infrastructure. Key features of the EP1S30F780C7N include embedded RAM of 3,317,184 bits distributed across TriMatrix memory blocks, four phase-locked loops (PLLs) for clock management, support for multiple I/O standards (LVTTL, LVCMOS, PCI, LVDS, SSTL, HSTL), and a dedicated JTAG boundary-scan interface conforming to IEEE 1149.1. The device supports both passive serial (PS) and fast passive parallel (FPP) configuration schemes using an Altera-enhanced configuration device. Architecturally, the Stratix family combines a sea-of-LEs fabric with column-based DSP and memory blocks, allowing engineers to implement wide datapath operations, packet processing, and high-throughput DSP functions on a single chip. The embedded memory enables First-In-First-Out (FIFO) buffers, lookup tables, and dual-port RAM; the DSP blocks provide dedicated multipliers and adders for FIR filters, FFTs, and video processing. Compared with the older APEX family, Stratix moved to 130 nm and added true LVDS support and dedicated high-speed transceivers in higher-density members. Typical applications include telecommunications backplane switching, network interface cards, high-speed serial protocol bridging (UTOPIA, SPI-4.2, SFI-4, 10 GbE MAC), digital video broadcasting, and high-performance DSP prototyping. Industrial 0 C to 85 C operation makes the part suitable for thermally-controlled telecom and computing equipment. When designing with this part, allocate sufficient decoupling (typically 100 nF plus bulk 10-100 uF near each VCC/GND pair) and follow Stratix power-up sequencing requirements to keep VCCINT and VCCIO rails within the recommended ramp rates. Quartus II (or Quartus Prime in later releases) is the primary development environment; legacy Quartus II 9.0 is the latest version with full support for this Stratix silicon.

EP1S30F780C8 - 32,470 LEs Stratix FPGA, 597 I/O, 780-FBGA | Intel
The Intel EP1S30F780C8 is a member of the original Stratix FPGA family built on a 130 nm CMOS process, offering 32,470 logic elements, 597 user I/O pins, and a top internal operating frequency of approximately 357 MHz, all integrated into a 780-ball FineLine BGA (FC-FBGA) package measuring 29 mm × 29 mm with a 1.0 mm ball pitch. A Field-Programmable Gate Array (FPGA) is a reconfigurable semiconductor device that combines programmable logic fabric, an interconnect matrix, and dedicated silicon IP (block RAM, DSP blocks, PLLs, transceivers) on a single die. Stratix sits in the hierarchy programmable logic device (PLD) → FPGA → high-performance FPGA, and was Intel/Altera's first family to combine embedded TriMatrix memory, embedded DSP blocks, and high-speed I/O on a 1.5 V core supply. Key features of the EP1S30F780C8 include embedded TriMatrix memory blocks for distributed and true-dual-port RAM/ROM, embedded DSP blocks for high-throughput fixed- and floating-point math, support for external memory interfaces such as DDR, DDR2, QDR, and ZBT SRAM, and dedicated high-speed I/O supporting LVDS, LVPECL, PCI, PCI-X, and HSTL signalling. The device also includes up to 12 dedicated clock pins with on-chip PLLs for fine-grained clock management, plus configuration via passive serial (PS), passive parallel synchronous/asynchronous (PPS/PPA), fast passive parallel (FPP), and JTAG. Architecturally, the EP1S30F780C8 uses Altera's Logic Array Blocks (LABs) interconnected by a multi-level routing fabric, with embedded memory columns interleaved with DSP block columns to maximise data-path throughput. The 1.5 V core, 130 nm process and flip-chip FC-FBGA package together deliver the speed and signal-integrity margins required for parallel DSP, ASIC prototyping, and high-bandwidth glue-logic designs at industrial 0–85 °C operating temperatures. Typical applications include ASIC prototyping, telecom line-card processing, high-speed image and video pipelines, communications infrastructure such as DSLAM and protocol bridges, and military/aerospace signal processing. Engineers also adopt EP1S30F780C8 for production-bound designs where time-to-market outweighs the unit-cost advantage of a structured ASIC, and as a software-compatible migration path to the larger Stratix II (EP2S) family. When designing with the EP1S30F780C8, plan power sequencing carefully: the 1.5 V core, I/O banks and auxiliary supplies must ramp in the order specified in the Altera Stratix device handbook to avoid in-rush latch-up. The 780-ball FC-FBGA demands reflow profile matching IPC/JEDEC J-STD-020 MSL-3 conditions, and high-speed LVDS traces must be length-matched to within the datasheet tolerance to meet the supported 840 Mbps data rate. This page synthesises distributor pricing, FFF-verified drop-in alternatives, and practical board-design notes not found in the manufacturer datasheet, helping sourcing engineers and FPGA designers plan a Stratix BOM with confidence.

Configuration is supported via Altera's passive serial, fast passive parallel, passive parallel asynchronous, and JTAG modes. Architecturally, the EP1S30F780C8N uses SRAM-based configuration cells with lookup-table (LUT)-based logic elements, carry chains for arithmetic, and dedicated routing. The embedded TriMatrix memory supports true dual-port, simple dual-port, and single-port RAM/ROM in various depths and widths, while DSP blocks provide hardware multipliers for filter and FFT structures. PLL blocks provide clock multiplication, division, and phase shifting for system timing. Typical applications include telecom baseband processing, high-speed image and video pipelines, test-and-measurement instrumentation, DSP co-processing cards, and communications line cards. Designers commonly pair this device with external DDR SDRAM, Flash configuration memory, and high-speed ADCs/DACs. For new designs, designers are advised to evaluate Stratix II EP2S30 or Cyclone IV/MAX 10 families as modern alternatives because Stratix (original) is a mature generation.

Typical applications include ASIC prototyping for networking line cards, telecom baseband preprocessing, military/defense signal processing, broadcast video switching fabrics, and high-performance DSP co-processing. Its combination of high logic density and embedded memory also made the part popular for early Software Defined Radio (SDR) and image processing pipelines. When designing with this part, allocate generous PCB routing layers for the 1.27 mm-pitch BGA, use multiple decoupling capacitor values (0.1 µF, 1 µF, 10 µF) per power pin, and verify signal-integrity on high-speed LVDS and clock traces. The legacy -6 speed grade indicates slower timing closure than -7/-8 grades; budget 15-25 % additional timing margin. Engineers should consult the official Stratix Device Handbook for transceiver and PLL block-level schematics before tape-out.

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.

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.

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 - 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.

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.

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.

FPGAs sit in the programmable-logic branch of the broader semiconductor taxonomy (FPGA -> programmable logic -> digital IC -> integrated circuit) and are commonly deployed as hardware accelerators, prototyping platforms, and glue-logic bridges between processors and high-speed peripherals. Key device features for the EP1S40F1020C7N include 3,423,744 embedded RAM bits distributed across TriMatrix memory blocks, embedded DSP blocks with hardware multipliers, and support for multiple I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and HSTL through dedicated I/O banks. 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. The combination of block RAM, embedded multipliers, and high I/O count makes the part particularly well-suited to wide datapath designs and parallel processing. When designing with this part, ensure the PCB uses controlled-impedance routing for high-speed I/O banks, follow Intel Stratix hardware reference design guidelines for power-plane decoupling, and verify the configuration scheme (PS, AS, JTAG) against the chosen configuration memory density. This page synthesizes distributor pricing, same-family drop-in alternatives, lifecycle observations, and practical design notes not found in the original Stratix datasheet, providing a single reference for engineers evaluating the EP1S40F1020C7N for new designs or as a long-term replacement target.

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. This page synthesises distributor pricing, drop-in alternatives drawn from the Stratix family, and practical design notes not found in the manufacturer datasheet alone.

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 device operates at a core voltage of 1.5 V across a commercial 0 to 85 C junction range and provides 773 user I/Os through its 1020-pin FC-FBGA (33 x 33 mm, 1 mm pitch) interface. An FPGA (Field-Programmable Gate Array) is a programmable semiconductor that lets designers implement custom digital logic, memory, and DSP blocks after manufacture. FPGAs sit at the top of the programmable logic hierarchy - alongside CPLDs - and are classified as integrated circuits (ICs) within embedded computing. The Stratix family specifically targets high-performance signal processing, telecommunications, and ASIC prototyping workloads where logic density, on-chip memory bandwidth, and DSP throughput matter most. Key features of the EP1S40F1020I6N include 4125 LABs grouped into the Stratix Logic Array architecture, embedded TriMatrix memory blocks totaling approximately 3.4 Mbits, dedicated DSP blocks for fixed-point arithmetic, and high-speed I/O supporting LVDS, LVTTL, SSTL, and other common signaling standards. The device also supports multiple configuration schemes including passive serial, passive parallel, and JTAG, allowing flexible in-system programming. On the architectural side, the EP1S40F1020I6N uses SRAM-based configuration memory with dedicated routing resources optimized for timing closure. Embedded PLLs provide clock synthesis and skew management across the die. The integrated DSP blocks can be cascaded for high-throughput FIR filters and FFT engines, while the TriMatrix memory (MLAB, M512, M4K blocks) offers flexible on-chip buffering for streaming data paths. Typical applications include ASIC prototyping and emulation, software-defined radio (SDR), high-speed image and video processing, telecom baseband processing, and military/aerospace signal processing. The 1020-BGA package supports dense board layouts while providing adequate signal integrity for multi-hundred-MHz parallel buses. When designing with this part, plan power sequencing carefully - the Stratix family typically requires a 1.5 V core plus separate VCCIO banks, VCCPD, and VCCAUX rails. A multi-rail controller is recommended to ensure proper power-up and configuration hand-off. Thermal management should account for the BGA's thermal resistance under full DSP utilization.

EP1S40F1508C6NGA - Stratix FPGA, 41250 LEs, 1508-BGA | Intel
Intel EP1S40F1508C6NGA is a Stratix family Field-Programmable Gate Array (FPGA) housed in a 1508-ball FineLine BGA package (FCBGA-1508) and built on a 0.13 µm process. It integrates 41,250 logic elements, 822 user I/O pins, and approximately 3,423,744 bits of embedded RAM, delivering high-density programmable logic for demanding signal processing and datapath applications. A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and dedicated hard IP such as block RAM, DSP blocks, and high-speed transceivers. FPGAs sit in the broader programmable-logic taxonomy between CPLDs (smaller, non-volatile glue logic) and ASICs (mask-programmed custom silicon), offering hardware-reconfigurable parallelism for compute-intensive workloads. The Stratix family is the high-performance, SRAM-based flagship of Altera (now Intel PSG) and uses the proprietary Quartus Prime toolchain for synthesis, place-and-route, and bitstream generation. Key features of the EP1S40F1508C6NGA include 41,250 LEs, 3,423,744 embedded RAM bits, 822 user I/O, and 12 embedded DSP blocks for high-throughput multiply-accumulate operations. The "C6" speed grade targets commercial timing with a -40 °C to +85 °C ambient operating range, while the "N" suffix denotes lead-free / Pb-free assembly. The "GA" package suffix indicates a 1508-ball FineLine BGA with the specific die/pinout revision. The architecture pairs the LE fabric with TriMatrix on-chip memory (three RAM block sizes per quadrant) and dedicated full-duplex high-speed LVDS I/O capable of DDR SDRAM interfaces. The device supports multiple I/O standards including LVTTL, LVCMOS, SSTL, HSTL, LVPECL, LVDS, and PCI/PCI-X, and includes up to 12 PLLs for clock synthesis and skew management. Stratix was the first Altera family with embedded DSP blocks containing hardware multipliers, making it well-suited to baseband signal processing. Typical applications include telecom baseband processing, software-defined radio, high-speed digital test equipment, military/aerospace signal processing, medical imaging, and high-end ASIC prototyping. The combination of 822 I/O and 12.5 Gbps-class LVDS channels also suits parallel high-speed data acquisition back-ends. Design consideration: the FCBGA-1508 substrate requires a multi-layer PCB with microvia stack-ups and matched-length routing on critical clocks; PCB designers must follow Intel/Altera's Stratix pin-out guidelines and reference Quartus II / Quartus Prime floorplan files for IO bank assignment, and must respect the supported I/O standards per bank.

Key features of the EP1S40F780C include 4× clock multiplier PLL blocks, support for external DDR and QDR memory interfaces, and a 4-Mbit embedded memory fabric configurable as RAM, ROM, or FIFO. The 780-pin BGA exposes 615 user I/O pins distributed across multiple I/O banks supporting LVDS, LVTTL, LVCMOS, SSTL, and HSTL standards. The 'C' suffix denotes the commercial temperature grade (0°C to +85°C), while the 'F780' package code indicates the 780-ball FBGA. The EP1S40F780C uses a 1.5V core supply with 0.13 µm process technology, balancing performance with reasonable dynamic power consumption. High-speed transceivers operate independently of the core logic, simplifying PCB routing for gigabyte-per-second serial links. The architecture supports partial reconfiguration via the JTAG interface, allowing live hardware updates in deployed systems. Typical applications include high-end router/switch fabric, baseband processing, radar signal acquisition, video broadcast encoders, and high-performance DSP accelerators. Commercial-grade parts are typically deployed in temperature-controlled environments such as central offices and laboratory instrumentation. When designing with this device, careful PCB layout for the 780-ball BGA, decoupling strategy, and high-speed signal integrity analysis are critical. JTAG configuration via a standard ByteBlaster or USB-Blaster cable is required for programming.
