It supports up to 38400 logic elements of effective logic capacity with high-speed LVDS, LVTTL, LVCMOS, PCI, and HSTL I/O standards, and integrates dedicated MultiCore Interconnect (MultiWire) routing fabric for predictable timing closure. An FPGA (Field Programmable Gate Array) is a programmable logic device that allows designers to implement arbitrary digital logic through a configurable array of logic elements, embedded memory blocks, multipliers, and routing. FPGAs belong to the broader hierarchy of programmable logic devices (PLD), sitting between simple CPLDs (Complex Programmable Logic Devices) and ASICs (Application Specific Integrated Circuits). APEX II is positioned as a high-density, system-on-chip-capable programmable platform in Intel/Altera's portfolio, optimized for parallel datapaths, on-chip memory intensive designs, and high-throughput I/O. Key features of the EP2A40B724CP include 40,000 typical logic elements, 655,360 RAM bits, support for multiple I/O standards, dedicated phase-locked loops for clock management, in-system programmability via JTAG, and hot-socketing support. The device operates on a 1.5V core supply with separate VCCINT and VCCIO planes for I/O bank flexibility. Embedded multiplier blocks and True-LVPECL/LVDS I/O enable high-speed serial datapath implementation directly in fabric. From an architectural standpoint, the APEX II family uses a MultiCore architecture with embedded system blocks (ESBs) that double as either dual-port RAM, ROM, or content-addressable memory (CAM). The MultiWire interconnect provides continuous routing across all hierarchy levels, which simplifies place-and-route closure versus older segmented FPGA fabrics. Each logic element includes a 4-input look-up table, a programmable register, and dedicated carry chain logic for arithmetic operations. Typical applications for the EP2A40B724CP include telecommunications backplane aggregation, high-speed protocol bridging, digital signal processing pre-processing, ASIC prototyping, and industrial control logic consolidation. Designers select the EP2A40B724CP when designs require more than 25K LEs, multiple high-speed I/O banks, and large on-chip memory for packet buffering or coefficient storage. When designing with the EP2A40B724CP, plan for 1.5V core decoupling with multiple bulk and ceramic capacitors near each VCCINT ball, and use the Quartus II design software for synthesis and place-and-route. Verify JTAG chain integrity before in-system programming to avoid configuration failures on production boards. Thermal management must account for the BGA package's thermal resistance under full I/O switching load.

The "I-7" suffix denotes the industrial operating temperature grade and the speed grade -7, optimized for high-performance processing with maximum clock frequencies in the 250-300 MHz internal range. The device integrates up to 1.5 Mbits of embedded SRAM organized into EAB blocks, plus four phase-locked loops (PLUs) for advanced clock management and on-chip termination support. An FPGA is a semiconductor device containing programmable logic blocks, programmable interconnects, and I/O pads that can be reconfigured after manufacturing to implement arbitrary digital circuits. FPGAs sit at the top of the programmable logic hierarchy alongside CPLDs (Complex Programmable Logic Devices) and are used for parallel processing, high-speed glue logic, and rapid prototyping of custom ASIC functionality. APEX II devices extend this concept with multi-core architecture (Lite, Fast, and I/O structures) suitable for high-bandwidth DSP and communications workloads. Key features of the EP2A40B724I-7 include 4 PLLs, embedded memory blocks, multi-voltage I/O support (1.5V, 1.8V, 2.5V, 3.3V LVTTL/LVCMOS), and 8 clock pins per device plus 16 dedicated clock inputs. The BGA-724 package provides a 33x33 mm footprint with 1.27 mm ball pitch, enabling high pin density for high-I/O applications. Configuration is supported via Altera enhanced configuration devices, supporting fast serial or parallel modes with decompression capability.

The Altera (now Intel PSG) EP2A40B724I-8 is a member of the APEX II programmable logic family, delivering 38,400 logic elements (LEs) and 655,360 bits of embedded system RAM in a 724-ball FineLine BGA package with 540 user I/O pins. As the largest member of the APEX II family, the EP2A40 targets high-density, high-performance system-on-chip integration, integrating up to 1,680 Kbits of True Dual-Port RAM and up to 1.05 Mbits of CAM. The -8 speed grade and industrial -I temperature rating place this part in the broader APEX II line's commercial-to-industrial envelope. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that combines the density of an ASIC with the flexibility of in-system reprogrammability. FPGAs sit higher in the programmable-logic hierarchy than simple CPLDs: they provide fine-grained look-up tables (LUTs), embedded RAM blocks, DSP multipliers, and high-speed I/O that together implement complex datapaths, protocol controllers, and even soft processor cores. The APEX II architecture, released in the late 1990s, pioneered MultiCore interconnect and combines LUT-based logic with embedded RAM and CAM blocks - the engineering lineage that ultimately evolved into today's Stratix, Cyclone, and Arria device families. Key features of the EP2A40 include 38,400 logic elements organized into 3,840 logic array blocks (LABs), a hierarchical memory architecture (ESBs - Embedded System Blocks) totaling 655 Kbits, and 540 user I/O pins enabling wide parallel buses and multiple high-speed interfaces. The device supports LVTTL, LVCMOS, PCI, GTL+, and other popular I/O standards, and integrates 4 PLLs for clock management. The 724-BGA FineLine BGA package is a surface-mount, wire-bond BGA with a fine-pitch ball grid suitable for high-I/O-count designs. The APEX II architecture uses a MultiCore interconnect that links LABs to ESBs via direct and row/column interconnect lines, supporting pipelined datapath operation at hundreds of MHz internally. The device operates from a 1.5 V core supply and supports multiple I/O voltage banks. Because APEX II predates modern serial transceivers, high-speed parallel I/O and external clocking are the standard integration path. Typical applications include telecommunications line cards and protocol engines, ASIC prototyping, custom DSP pipelines, high-speed data acquisition front-ends, and industrial control systems. The 540 user I/Os and large RAM/CAM blocks also make the EP2A40 attractive for deep-packet inspection and ATM/Sonet networking designs. When designing with this FPGA, verify the Quartus version compatibility: APEX II is supported by Quartus II (legacy toolchains), and Intel currently maintains it as a mature device for legacy re-designs. Power sequencing, decoupling, and JTAG configuration topology follow the standard Altera BGA guidelines in the device handbook.

The 'B724' suffix indicates the 724-pin FCBGA package, the 'I' suffix indicates an industrial temperature grade (-40C to +100C operating junction range typical of APEX II), and the '9' suffix denotes a speed grade designation consistent with Altera's APEX II speed bin system. Peak reflow temperature per the manufacturer profile is rated at 220 C. An FPGA (Field Programmable Gate Array) is a reprogrammable semiconductor device whose logic fabric, interconnect, and I/O routing are configured by a user-supplied bitstream, rather than fixed at the fab. APEX II sits in the hierarchy: programmable logic device (PLD) -> Complex Programmable Logic Device (CPLD)/FPGA -> high-density SRAM-based FPGA -> APEX II family, all under the broader class of programmable logic ICs. APEX II parts integrate Look-Up Tables (LUTs), Embedded System Blocks (ESBs) for dual-port RAM/ROM, and FastTrack interconnect, making them suitable for high-throughput datapath, memory-interface, and bus-bridge designs. Key features include 540 maximum user I/O pins (as observed in the closely related EP2A40B724C9 variant listed by Rochester Electronics on DigiKey), 655,360 embedded memory bits organized as 16-bit-wide ESBs, an embedded multiplier block architecture, support for multiple I/O standards (LVTTL, LVCMOS, PCI, SSTL), and 3.3 V core / multi-standard I/O operation with on-chip PLLs for clock conditioning. The device supports configuration via Altera serial/parallel configuration schemes using the dedicated JTAG or passive serial interface. Architecturally, the APEX II device combines a fine-grained LUT-based fabric with row/column FastTrack routing, dedicated carry chains for arithmetic, ESBs for distributed and block RAM, and PLL-based clock management. This combination yields a flexible platform for high-density datapath, telecom, and embedded processing subsystems. The B724 package exposes the full I/O count of the device, so the EP2A40 is the high-pin-count die option of the APEX II family. Typical applications include telecommunications line cards, network switching fabrics, industrial control and instrumentation, image and video processing pipelines, ASIC prototyping, and high-speed data acquisition front-ends. The high pin count and substantial on-chip memory also suit bus-bridge and protocol-translation designs where a parallel CPU or DSP bus is mapped to a high-throughput serializer. When designing with EP2A40B724I-9, ensure thermal analysis accounts for industrial-temperature corner cases, and verify signal integrity at full 540-pin I/O utilization. APEX II parts are NRND/EOL on Altera/Intel's roadmap, so lifecycle planning and pin-compatible Cyclone IV/V or Stratix migration should be evaluated for new designs. Compared with the EP2A40B724C9 (commercial grade, no '-I-' suffix), the EP2A40B724I-9 extends the operating range and is the correct choice when the design will see -40 C exposure.

Architecturally, the EP2A40B724I7 uses Altera's MultiCore fabric: each logic array block (LAB) contains multiple logic elements (LEs) built from 4-input LUTs, and rows of ESBs (Embedded System Blocks) provide 2 Kbit memory blocks that can be configured as RAM, ROM, or product-term logic. The device is configured via SRAM, allowing in-system reprogrammability through JTAG or passive/active serial modes. The 724-pin FCBGA gives the design hundreds of general-purpose I/O and dedicated clock pins, sufficient for high-speed parallel buses and source-synchronous interfaces. Typical applications include ASIC prototyping and emulation, telecom line-card glue logic, high-speed serial protocol bridging, industrial control and machine vision pipelines, and military/aerospace digital signal processing front-ends. Its large memory capacity and LVDS support make it well suited for video processing and image buffering subsystems. When designing with the EP2A40B724I7, observe 1.5 V core supply decoupling with low-ESR ceramic capacitors placed adjacent to the package, ensure JTAG chain integrity, and confirm the Quartus (or legacy MAX+PLUS II / Quartus II) toolchain supports the chosen pin assignments and I/O standards. APEX II devices are NRND/EOL at Intel; verify lifetime availability before new design commitment.

The trailing "I9" suffix denotes industrial temperature grade with speed grade 9 (slower but more robust timing margin). What is an FPGA? An FPGA (Field-Programmable Gate Array) is a reprogrammable semiconductor device built from an array of configurable logic blocks (LABs/MegaLABs), embedded memory, and programmable interconnect. FPGAs occupy a tier above CPLDs and below ASICs in the programmable-logic hierarchy: FPGA > CPLD > SPLD > PAL/GAL. APEX II was Altera's second-generation multi-gigabit-capable architecture, designed for high-speed communications, DSP, and processor-coprocessor emulation, before being succeeded by Stratix, Cyclone, and finally Agilex families. Key features of the EP2A40B724I9 include 38,400 logic elements, 655,360 bits of embedded SRAM distributed across multiple embedded array blocks (EABs), built-in support for LVDS, LVTTL, LVCMOS, PCI, SSTL, and GTL+ I/O standards, and up to 16 high-speed clock networks with dedicated PLL blocks for frequency synthesis and clock deskew.

Each EAB provides 2,048 bits of memory, and the embedded multiplier structure accelerates DSP building blocks such as FIR filters and FFT butterflies. Multi-gigabit transceivers and LVDS I/O support line rates up to several hundred Mbps per channel. Typical applications include high-speed serial protocol bridging (UTOPIA, POS-PHY, RapidIO), telecom line cards, base-station channel cards, image-processing pipelines, and ASIC prototyping. The large logic capacity also makes EP2A40B724I9 suitable for system-on-chip emulation of processor peripherals and bus architectures. Designers typically target the device with the Quartus II design suite (legacy) for synthesis, place-and-route, and timing closure. When designing with EP2A40B724I9, ensure adequate decoupling: 0.1 µF and 0.01 µF high-frequency ceramics must be placed within 100 mils of every power pin, plus bulk decoupling at the board level. The 1.5 V core supply requires tight regulation; a drop of more than 5 % can cause functional failure. Note that APEX II parts are legacy/EOL, so long-term production programs should validate second-source options or migration to Stratix/Agilex equivalents. This page consolidates distributor pricing, drop-in alternative candidates, package data, and design notes beyond the original datasheet, helping sourcing engineers and hardware designers evaluate the EP2A40B724I9 for both new designs and legacy board maintenance.
EP2A40B724I9N - APEX II 1.5M Gates FPGA, 724-FCBGA | Intel
The Intel EP2A40B724I9N is a high-density member of the APEX II family of programmable logic devices, fabricated on a 0.15 µm CMOS process and supplied in a 724-pin FineLine BGA (FCBGA) package. It integrates 1.5 million system gates, 38,400 logic elements, and embedded system blocks to support high-performance data-path and DSP-intensive designs up to 366 MHz internal operation. The device core operates at 1.5 V with multi-voltage I/O support, and the part is specified for the industrial temperature range (-40 °C to +100 °C), as denoted by the "I9" speed/temperature code. What is an FPGA? An FPGA (Field-Programmable Gate Array) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable interconnects, and embedded memory/DSP/multiplier blocks that can be rewired after manufacture to implement arbitrary digital logic. APEX II belongs to the PLD (Programmable Logic Device) hierarchy: PLD -> CPLD/FPGA -> high-density SRAM-based FPGA -> system-on-a-chip capable FPGA, and is used where ASIC-level integration is needed but flexibility is required for late-stage design changes or field upgrades. Key features of the EP2A40B724I9N include four-phase PLL clock management, embedded CAM blocks, True-LVDS support, multi-standard I/O with 3.3 V/64 mA drive strength, and dedicated multiplier blocks for DSP pipelines. The device supports configuration via passive serial (PS), passive parallel synchronous/asynchronous (PPS/PPA), and JTAG-based in-system programming, enabling remote bitstream updates in deployed systems. Hot-socketing capability allows board-level insertion without device damage. The architecture combines Look-Up Table (LUT)-based logic elements with embedded array blocks (EABs) that implement RAM, ROM, and CAM functions. Fast row/column interconnect, multi-tier pipelining, and dedicated carry chains deliver predictable timing closure for synchronous datapaths. The 1.5 V core reduces dynamic power versus 2.5 V predecessors by approximately 40 percent. Typical applications include high-speed telecom line cards, DSP-based baseband processing, RAID controllers, SONET/SDH framer/mapper ASIC replacements, and pre-silicon prototyping of ASIC designs. The 724-pin FCBGA package provides a 1.27 mm pitch, suitable for 8-layer or higher-density PCB stack-ups with controlled-impedance routing. Designers should plan power sequencing because the APEX II core requires 1.5 V before I/O ramp. Decoupling requires 0.1 µF and 0.01 µF capacitors within 5 mm of every VCC pin. For legacy replacement, verify bitstream compatibility against the Quartus II 4.2 or later development environment since the APEX II family is no longer actively recommended for new designs.

Key features include 1.6 million maximum system gates, 40,960 typical gates, embedded ESBs for dual-port RAM, FIFO, and content-addressable memory (CAM), four phase-locked loops (PLLs) for clock management, and MultiVolt I/O support for mixed-voltage interfacing. The device supports in-system programmability via the IEEE 1149.1 (JTAG) interface and Altera's passive serial, passive parallel, and passive asynchronous configuration schemes. Per Altera's APEX II datasheet (verified across distributor listings as of 2026-09-08), the part operates from a 1.8 V core supply with MultiVolt I/O that can interface to 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V systems. Architecture details: the APEX II family uses a row-and-column architecture with embedded system blocks replacing every four logic array blocks (LABs). Each ESB provides 2,048 bits of dual-port RAM or ROM, supports FIFO depths of 128x16 or 256x8, and includes dedicated carry chains for arithmetic. The four PLLs provide frequency synthesis, phase shifting, and clock de-skew, while the MultiVolt I/O structure allows the part to bridge legacy 5 V logic to modern low-voltage cores. Typical applications span high-speed telecommunications backplanes, ATM switching fabric control logic, SONET/SDH framer ICs replacement, large cache controllers, and ASIC prototyping. The EP2A40F1020C6 is also commonly used in industrial vision and imaging pipelines, where the embedded FIFO memory and dual-port RAM are leveraged to buffer high-bandwidth pixel streams. Designers should plan their thermal strategy around the FBGA-1020 package's junction-to-ambient thermal resistance (θJA), because the 1.6M-system-gate device can dissipate substantial power at high toggle rates. Designers should also review Altera's Quartus II (legacy APEX II support) or Quartus Prime toolchain compatibility, as the most recent Quartus versions are end-of-support for this legacy family.
EP2A40F1020C6N - APEX II 40K LE FPGA, 1020-FBGA | Altera
The Altera EP2A40F1020C6N is a member of the APEX II family of programmable logic devices, delivering 40,000 logic elements (LEs) and up to 735 user I/O pins in a 1020-ball fine-pitch BGA package (FBGA-1020). It combines high-density look-up table (LUT) logic with embedded dual-port RAM blocks, providing a flexible platform for ASIC prototyping, custom DSP pipelines, and high-throughput glue logic on 0.15 µm process technology. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device that lets designers implement arbitrary digital logic through a configuration bitstream rather than masked silicon. APEX II sits within the broader taxonomy of CPLD/FPGA > programmable logic > logic IC > integrated circuit. Compared with older CPLDs, FPGAs like the APEX II family provide register-rich datapaths and on-chip memory, while remaining reprogrammable in-system via JTAG. Key features include 40,000 logic elements, 655,360 bits of embedded RAM, dedicated MultiCore multipliers for DSP, and support for multiple I/O standards including LVTTL, LVCMOS, PCI, SSTL, and LVDS. The device is powered by a 1.5 V core supply and offers user-selectable I/O voltages, with hot-socketing support for live insertion applications. The APEX II architecture combines four types of structured ASIC blocks — LUTs, product-term logic, dual-port RAM, and high-speed MultiCore multipliers — on a single die. This heterogeneous fabric allows the EP2A40 to accelerate datapath-intensive designs (e.g., FFTs, FIR filters, packet processors) while still handling glue logic and state machines efficiently. The LUT-based elements operate at core speeds well into the 100+ MHz range in typical designs. Typical applications include high-speed telecom interface cards, ASIC prototyping, custom DSP front-ends, broadcast video processing, and industrial control systems requiring large I/O counts. Its 735 user I/O also suit backplane bridging, where many buses must be observed or driven simultaneously. Designers should plan for the 1020-ball FBGA as a fine-pitch (likely 1.27 mm or 1.0 mm pitch) package requiring multilayer PCB with buried vias, controlled-impedance traces, and matched-length routing for LVDS/clock pairs. Power-rail sequencing and decoupling follow standard Altera APEX II reference designs. This page consolidates distributor availability, APEX II same-family drop-in alternatives, and design considerations not found in the original 99-page Altera APEX II datasheet — useful when the original part is in tight supply.

Key features of the EP2A40F1020C7 include 2,560 macro cells, 735 user I/Os, and high-speed serial support through 1-Gbps True-LVDS, LVPECL, PCML, and HyperTransport interface signaling. The device exposes roughly 655 kbits of embedded memory for buffer, FIFO, and ROM/RAM functions, while dedicated clock management blocks (PLLs) and Double Data Rate (DDR) support address timing-critical sections of the design. Altera's Quartus II design suite is the canonical toolchain for synthesis, place-and-route, and bitstream generation. The 1020-pin FC-FBGA package uses a fine-pitch flip-chip ball grid to maximize signal escape density and minimize inductance on high-speed nets; it requires a multi-layer PCB with controlled-impedance routing and BGA-specific rework capability. Industrial-grade thermal and reliability grades make the part applicable to communications backplanes, ASIC prototyping, and DSP co-processing, where high gate count and rich I/O outweigh the cost premium. When designing with EP2A40F1020C7, ensure your PCB stack-up supports the FC-FBGA ball pitch and that power decoupling follows the APEX II reference design (multiple bulk and high-frequency ceramic capacitors per VCC rail). Use Quartus II pin planning tools early to validate I/O assignment against bank voltage requirements and LVDS pairing rules.

EP2A40F1020C8N - 1.5M-Gate APEX II FPGA | Intel | Industrial Logic
Intel EP2A40F1020C8N is a field-programmable gate array from the APEX II family, integrating 1.5 million gates and 38,400 logic cells in a 1,020-ball fine-pitch BGA package. Verified sources identify a nominal 1.5 V supply, 735 user I/O pins, and either 376 MHz or 562 MHz as the reported operating-frequency figure, depending on source and interpretation. A propagation delay of 1.78 ns is also listed, alongside a separate 1.55 ns value in another source; this discrepancy is preserved for validation rather than reconciled by assumption. The device is fabricated using a 0.15 µm all-layer copper process with as many as eight metal layers. A field-programmable gate array, or FPGA, is a semiconductor device whose logic architecture, interconnections, and I/O behavior can be configured after manufacture. FPGAs occupy the programmable-logic tier between fixed-function application-specific integrated circuits and software-defined processors. APEX II devices combine reusable logic resources, programmable routing, embedded memory, and high-speed differential I/O, making them suitable for parallel data processing, communications, and industrial control. Within the semiconductor hierarchy, EP2A40F1020C8N is an FPGA, programmable logic device, CMOS integrated circuit, and programmable semiconductor. Its principal engineering attributes include 1.5 million gates, 38,400 cells, 735 user I/Os, and 1,020 BGA terminals. The reported logic process is 0.15 µm, while the package is described as 1020-pin FC-FBGA or BGA-1020 with a 33 mm by 33 mm body and 1 mm pitch. A 1.425 V to 1.575 V operating-supply range surrounds the nominal 1.5 V rail. These characteristics support systems that need dense parallel logic and many external interfaces. The APEX II architecture combines programmable logic cells with routing resources and dedicated I/O structures. The verified APEX II family documentation also describes 1 Gbps True-LVDS, LVPECL, PCML, and HyperTransport capabilities. Such interfaces permit point-to-point high-speed connections, although implementation requires the configuration, termination, and timing rules in the manufacturer datasheet. The 735 user I/O count gives designers substantial interface capacity, but power integrity and simultaneous-signal performance depend on board-level implementation. Typical applications include industrial automation, communications equipment, high-speed digital signal processing, protocol bridging, and test or measurement systems. The FPGA can implement parallel datapaths and control functions in one device, while the high pin count accommodates numerous buses, differential links, and memory or peripheral interfaces. The commercial temperature grade is reported as 0 °C to 85 °C, so systems intended for wider ranges require qualification and may need another device. Designers should first resolve the conflicting frequency and propagation-delay values against the exact APEX II family datasheet and selected speed-grade data. A fine-pitch 1,020-ball package also demands controlled-impedance routing, robust power distribution, correct decoupling, thermal analysis, and manufacturer-recommended BGA assembly. The nominal 1.5 V rail must remain within the stated 1.425 V to 1.575 V range. This page combines verified device specifications, package and supply constraints, source traceability, and practical replacement guidance. Because the cross-reference search returned no verified pin-compatible alternatives, engineers should use the EP2A40F1020C8N ordering code and APEX II datasheet as the controlling records when evaluating substitutes or planning board redesigns.

From an architecture standpoint, the APEX II family combines a look-up table (LUT) based logic fabric with embedded array blocks, allowing designers to mix fine-grained logic with wide datapath functions in the same device. The 0.15-µm process with eight copper layers enables both high density (38,400 cells) and a 366 MHz core frequency, while the multi-standard I/O ring supports PCI/PCI-X, AGP, GTL+, and HSTL without external level shifters, simplifying board design. Typical applications include PCI/PCI-X bridge cards, high-speed serial protocol bridges, telecommunications backplane controllers, ASIC prototyping platforms, and high-density DSP or datapath engines. The 735 user I/Os and embedded memory make it attractive for designs that previously required multiple FPGAs plus a bridging ASIC. When designing with this part, validate the 1020-pin FC-FBGA land pattern and ensure PCB stack-up supports 1 mm BGA pitch with microvia or via-in-pad technology as required. Verify the speed grade C9 timing against your critical path before committing layout, and confirm Intel's Quartus/APEX support status since APEX II is a mature family.

FPGAs sit in the hierarchy of programmable logic devices -> CPLD -> FPGA -> programmable SoC, occupying the high-density end of the programmable logic spectrum. APEX II FPGAs in particular combine look-up-table based logic with embedded memory blocks (ESBs) and high-speed I/O, making them suitable for DSP, telecom, and parallel datapath implementations. Key features of the EP2A40F1020I7 include 38,400 logic cells, 1.5M system gates, embedded system blocks (ESBs) for memory and arithmetic, and 4 phase-locked loops (PLLs) for clock management. The device supports LVTTL, LVCMOS, PCI, and LVDS I/O standards, and provides multi-voltage I/O support for mixed-voltage system interfacing. Four high-speed clock networks and dedicated routing minimize skew across the die. The APEX II architecture combines coarse-grained look-up tables with dedicated carry chains, embedded RAM, and multipliers, allowing efficient implementation of both control logic and datapath-intensive DSP functions. The 1.5 V core voltage and 0.15 µm process balance performance against power dissipation, while the 1020-ball FC-FBGA package exposes the full I/O count needed for high-bandwidth memory and bus interfaces. Typical applications for the EP2A40F1020I7 include telecommunications infrastructure (SONET/SDH framers, base-station DSP), high-speed data acquisition systems, broadcast video processing, custom accelerator cards, and ASIC prototyping platforms. Industrial temperature grading extends usability into factory automation and outdoor equipment. When designing with this part, plan power sequencing for the 1.5 V core and the I/O supply rails, and provide adequate decoupling across the 1020 balls. Use Altera Quartus II (legacy) for synthesis, place-and-route, and timing closure; the device is now considered mature and may be best sourced through the secondary market.

It provides 735 user I/O pins and operates across an industrial temperature range of -40C to +85C, making it suitable for high-performance digital designs. An FPGA (Field-Programmable Gate Array) is a programmable logic device consisting of an array of configurable logic blocks (CLBs), programmable interconnect, and dedicated I/O cells. FPGAs sit at the top of the programmable logic taxonomy: FPGA -> programmable logic -> digital IC -> semiconductor. They are typically chosen over ASICs when designs require rapid prototyping, mid-volume production, or in-field reprogrammability, and over CPLDs when higher logic capacity, DSP throughput, or embedded memory bandwidth is needed. The EP2A40F1020I8 is built on a 0.18-micron process and offers embedded array blocks (EABs), high-speed True-LVDS support, and multi-level interconnect hierarchy.
