EP2A40B724I9 - APEX II FPGA, 1.5M Gates, 724-FCBGA | Intel / Altera
The Intel / Altera EP2A40B724I9 is a high-density member of the APEX II (Advanced Programmable Embedded Matrix) FPGA family, providing 1,500,000 system gates and 38,400 logic elements in a 724-pin FineLine BGA (FCBGA) package. Built on a 0.15 µm CMOS process, the device supports a core voltage of 1.5 V with industry-standard I/O standards, and operates across the industrial temperature range of -40 °C to +100 °C. 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. The device also integrates up to four phase-locked loops (PLLs) for clock multiplication and jitter control. The APEX II architecture combines look-up-table (LUT)-based logic with embedded system blocks (ESBs) that can each be configured as dual-port RAM, ROM, FIFO, or CAM. 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.

EP2A40F1020C6 - APEX II FPGA, 40k LE, FBGA-1020 | Intel / Altera
The Intel (formerly Altera) EP2A40F1020C6 is a member of the APEX II programmable logic device family, providing up to 40,000 typical gates of high-density logic in a 1020-ball FineLine BGA package. Built on a 0.15 µm CMOS process with embedded system blocks (ESBs) for memory and fast carry chains, this device targets system-on-a-chip (SoC) designs where high integration, predictable timing, and embedded memory bandwidth are required. 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 the user defines after manufacture via a configuration bitstream. Within the broader taxonomy, the APEX II family sits between conventional CPLDs and high-end FPGAs: APEX II = FPGA + embedded system block memory + PLLs, all part of the larger Programmable Logic Device (PLD) hierarchy that also includes SPLDs, CPLDs, and modern SoC FPGAs. The EP2A40F1020C6 specifically delivers high logic density (40k typical gates, ~1.6M system gates) and 655,360 bits of embedded SRAM distributed across embedded system blocks. 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.

The Altera EP2A40F1020C7 is a member of the APEX II family of Field-Programmable Gate Arrays (FPGAs), fabricated on a 0.15 micrometer all-layer copper-metal process with up to eight metal layers. The device integrates 1.5 million system gates and 38,400 logic cells in a 1020-ball Fine-pitch Chip-Scale BGA (FC-FBGA) package, delivering up to 562 MHz core performance from a 1.5 V core supply. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), embedded memory, and programmable I/O, all interconnected by a programmable routing fabric. APEX II sits in the high-density programmable logic hierarchy as: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit. APEX II devices combine Look-Up Table (LUT)-based logic with embedded array blocks (EABs), making them suitable for both register-rich datapath and memory-intensive designs on a single die. 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. This page synthesizes distributor inventory, same-family Altera drop-in alternatives, and practical FPGA bring-up notes that complement the manufacturer's datasheet, providing information gain beyond a single product listing.
EP2A40F1020C7ES - APEX II 1.5M Gates FPGA, 1020-FBGA | Intel
The Intel (formerly Altera) EP2A40F1020C7ES is a high-density FPGA from the APEX II device family, manufactured on a 0.15 µm all-layer copper process supporting up to eight metal layers. It integrates 1.5 million system gates, 38,400 logic elements, and 655,360 bits of embedded memory in a 1020-pin FC-FBGA package with 735 user I/O pins, optimized for 1.5 V core operation at system speeds up to 562 MHz. What is an APEX II FPGA? APEX II (Advanced Logic Element Matrix, second generation) is a programmable logic device family from Altera that combines look-up table (LUT) based logic, embedded system blocks (ESBs) for memory and arithmetic, and high-speed I/O on a single die. APEX II devices sit in the FPGA hierarchy above CPLDs and below ASICs, between simple programmable logic devices (SPLDs/CPLDs) and structured ASICs. They belong to the broader class of programmable logic devices (PLDs) and are typically deployed when design flexibility, high gate count, and parallel signal processing are required before committing to an ASIC tape-out. Key features include up to 1.5 million typical gates, 38,400 logic elements (LEs), 655,360 bits of embedded RAM, and 1 Gbps True-LVDS, LVPECL, PCML, and HyperTransport interface support. The 1020-pin FC-FBGA package exposes 735 user I/Os, enabling wide parallel buses and high-pin-count data acquisition. MultiVolt I/O allows interfacing to 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic levels without external level shifters. The device uses a hierarchical routing architecture with embedded array blocks (EABs) and logic array blocks (LABs), allowing efficient implementation of large multipliers, FIFOs, and dual-port RAM. True-LVDS support at 1 Gbps makes the part suitable for high-speed serial links and parallel chip-to-chip interconnect. Internal Phase-Locked Loops (PLLs) provide clock multiplication, division, and phase shifting across up to eight clock domains. Typical applications include high-performance data acquisition, ASIC prototyping, telecommunications infrastructure, parallel DSP pipelines, and high-speed image or video processing. The high I/O count makes it well-suited for bus-intensive bridging and protocol conversion designs. When designing with EP2A40F1020C7ES, follow Altera's power and thermal decoupling guidance carefully; a 1020-pin FC-FBGA demands multi-layer PCB with continuous power planes and a controlled-impedance stack-up. The 'ES' suffix indicates an enhanced speed grade, so verify timing closure with the Altera Quartus II design tool before tape-out. This page synthesizes distributor pricing, drop-in alternatives from the same APEX II family, and practical design notes not found in the manufacturer datasheet alone.
EP2A40F1020C7N - APEX II 1.5M Gates FPGA, 735 I/O, FC-FBGA-1020 | Intel
The Intel (formerly Altera) EP2A40F1020C7N is a high-density APEX II family FPGA delivering 1.5 million system gates and 38,400 logic elements on a 0.15 µm all-layer copper-metal process with up to eight metal layers. The device operates from a 1.5 V core supply (1.425 V to 1.575 V), supports True-LVDS, LVPECL, PCML, and HyperTransport™ I/O standards, and is packaged in a 1020-ball fine-line FC-FBGA measuring 33 × 33 mm with a 1.0 mm ball pitch. It offers 735 user I/O pins, four phase-locked loops, embedded system blocks (ESBs), and a 1 Gbps True-LVDS capability that made it a leading communications-edge device when introduced in 2002. An FPGA (Field-Programmable Gate Array) is a semiconductor device whose logic, interconnect, and I/O behaviour are defined by user-supplied configuration data rather than fixed at the fab. Within the programmable-logic hierarchy, FPGAs sit below ASICs in NRE cost but above CPLDs in capacity. The APEX II architecture is the second-generation APEX (Advanced Programmable eXtended Element) family, combining look-up-table-based logic elements with embedded array blocks for memory and arithmetic, making it suitable for high-throughput datapath and protocol-bridging designs. Key specifications of the EP2A40F1020C7N include 38,400 logic elements, 1.5 M system gates, 562 MHz maximum internal performance, 1.55 ns propagation delay, 735 user I/Os, 4 PLLs, and 12 clock networks. The fine-pitch FC-FBGA-1020 package uses flip-chip bumps for low inductance, allowing the high I/O count and 1 Gbps LVDS to coexist in a single 33 × 33 mm footprint without internal bond wires. The APEX II architecture combines distributed look-up tables with Embedded System Blocks (ESBs) that double as RAM, ROM, or product-term logic, giving designers 504 Kbits of embedded memory and dedicated carry chains for arithmetic. The four PLLs and twelve low-skew clock networks simplify multi-domain clocking in large protocol-bridge designs, while on-chip termination and controlled-impedance drivers support 1 Gbps LVDS interfaces directly without external resistors. Typical applications include high-speed serial protocol bridging (RapidIO, POSPHY, Utopia), telecommunications backplane aggregation, baseband signal processing, and parallel-to-serial data conversion in legacy telecom line cards. The combination of 38,400 logic elements and 1 Gbps LVDS made it a strong fit for 10 Gbps channelised interfaces when split across multiple LVDS lanes. When designing with this device, ensure the PCB uses microvia or via-in-pad technology to fan out the 1.0 mm-pitch FC-FBGA, and follow Altera's application-note guidelines for power-plane decoupling and thermal relief of the 33 × 33 mm fine-line BGA. Expect to consume Quartus II design software version 4.x or later for bitstream generation, as legacy APEX II support has been removed from newer Quartus releases. This page synthesises distributor inventory, FPGA family positioning, and design-toolchain notes for engineers evaluating the EP2A40F1020C7N in long-lifecycle telecom and industrial systems, complementing the manufacturer datasheet with information not found in a single source.

The device is fabricated on a 0.15 µm all-layer copper-metal CMOS process (up to eight metal layers) and operates from a 1.5 V core supply with a maximum internal clock frequency of 376 MHz. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), embedded memory, routing interconnects, and programmable I/O cells. FPGAs belong to the broader category of programmable logic devices (PLDs), which sit alongside ASICs (Application-Specific Integrated Circuits) in the digital logic hierarchy. APEX II devices combine Look-Up Table (LUT)-based logic with embedded system blocks (ESBs) that provide dual-port RAM, ROM, and CAM functions, enabling high-density datapath and memory-intensive designs. Key features of the EP2A40F1020C8 include 735 user I/O pins, 2,560 macro cells, a propagation delay of approximately 1.55 ns, MultiVolt I/O support for interfacing with 1.5 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V buses, and embedded LVDS-capable channels for high-speed differential signalling. The 1020-ball FC-FBGA package provides excellent signal and power integrity for designs requiring hundreds of I/Os and high pin-count board integration. The APEX II architecture combines four types of structured ASIC-like blocks (megaLAB, LAB, ESB, and FastTrack interconnect) to deliver predictable timing and high utilisation. The 1.5 V VCCINT core plus separate VCCIO banks allow mixed-voltage system design without external level shifters. The device supports in-system programmability via JTAG and Altera serial configuration schemes. Typical applications include high-speed telecommunications line cards, multi-channel data acquisition systems, RAID controllers, high-density glue-logic replacement, and protocol bridging ASICs. The 735 available user I/Os make it suitable for parallel bus interfaces and SDRAM controller implementations in embedded and industrial systems. When designing with the EP2A40F1020C8, allocate at least six PCB layers for power/ground planes and signal routing to maintain signal integrity for the 1.5 V core. Use the Altera Quartus II design suite (legacy 32-bit versions 4.x and earlier remain the recommended toolchain because APEX II predates Cyclone/Stratix support) for synthesis, place-and-route, and timing closure. Note that the APEX II family is now in mature lifecycle status - verify long-term availability before new design starts. This page synthesises distributor pricing, drop-in alternative ordering options, and practical board-level design considerations that are not consolidated on a single manufacturer page.
EP2A40F1020C8ES - APEX II FPGA 1.5M Gates 1020-BGA | Intel
The Intel EP2A40F1020C8ES is a member of the Altera APEX II family of programmable logic devices, delivering approximately 1,500,000 system gates and 40,960 logic elements in a 1020-ball FCBGA package. It provides 655,360 bits of embedded RAM, 735 user I/O pins, and operates from a 1.425 V to 1.575 V core supply with commercial 0 °C to 85 °C temperature grade. The C8 speed grade indicates an 8 ns pin-to-pin logic delay tier, targeting mid-performance embedded and communications designs. An FPGA (Field-Programmable Gate Array) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable interconnect, embedded memory, and hardened I/O serializers. Modern FPGAs sit at the same architectural tier as microcontrollers and DSPs in embedded systems, but offer hardware-level parallelism: instead of executing instructions sequentially, custom digital circuits are synthesized directly into the silicon fabric. APEX II devices belong to the broader category of programmable logic devices (PLDs), which also includes CPLDs, and historically descended from PAL/GAL architectures. Key features of the EP2A40F1020C8ES include 655,360 RAM bits distributed across embedded memory blocks, a high I/O count of 735 supporting a wide mix of single-ended and differential signaling standards, and APEX II's signature Look-Up Table (LUT) plus embedded memory dual-function architecture. The device supports in-system programmability via JTAG and configuration via passive serial, and integrates PLLs for clock management. Technically, the APEX II architecture uses a MultiCore interconnect matrix combining row and column routing with embedded memory blocks (ESBs), enabling efficient implementation of large datapaths and FIFOs. The 1020-BGA FCBGA package offers high signal density and thermal performance suitable for high-utilization designs; engineers should observe controlled-impedance routing and proper decoupling when laying out the PCB. Typical applications for this part include telecom line cards, industrial control and instrumentation, high-speed data acquisition front-ends, and ASIC prototyping. The high gate count makes it well-suited for designs requiring parallel processing pipelines, custom bus interfaces, or hardware acceleration. When designing with this FPGA, allocate sufficient PCB area for decoupling capacitors near each supply pin and follow Intel/Altera's recommended footprint and stack-up guidelines for fine-pitch BGA packages. Thermal management via thermal vias under the die and copper pours is recommended at high utilization.

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.
EP2A40F1020C9 - APEX II FPGA 1.5M Gates 38400 Cells 1020-FBGA | Intel
The Intel (formerly Altera) EP2A40F1020C9 is a high-density APEX II family FPGA with 1.5 million system gates, 38,400 logic elements, and a maximum internal clock frequency of 366 MHz, fabricated on a 0.15-micrometer all-layer copper-metal CMOS process with up to eight metal layers and housed in a 1020-pin FineLine BGA (FC-FBGA) package. The device integrates 2,560 macrocells, 735 user I/Os, and supports multiple I/O standards including LVTTL, LVCMOS, PCI/PCI-X 32/64-bit at 33/66/133 MHz, AGP, CTT, SSTL-2/SSTL-3 Class I & II, GTL+, and HSTL Class I & II, making it suitable for high-performance bridging and bus-interface applications.

The -8 speed grade specifies the slowest of three offered grades, which provides cost advantages for non-timing-critical designs. Moisture Sensitivity Level is MSL 3 per JEDEC J-STD-020, with a peak reflow temperature rating of 220C. EP2A40 devices combine four logic element groups, each containing ten LogicArray blocks, plus up to 1.125 Mbit of dual-port RAM implemented via embedded system blocks. Typical applications include PCI bus interfaces, high-speed DSP datapaths, telecommunications backplane bridging, and parallel coprocessing blocks. The 672-ball FBGA provides the I/O density required for wide datapath and external memory interfaces. When designing with this device, ensure MSL 3 handling procedures are followed during PCB assembly, as the plastic BGA absorbs moisture and requires a controlled bake-out before reflow. The -8 speed grade should be reserved for designs where timing margins exceed the slowest timing specifications. Use the Quartus II or MAX+PLUS II toolchain for synthesis, fitting, and timing analysis.
EP2A40F33C-9 - APEX II 40K FPGA, F33 FBGA-672 | Intel / Altera
The Intel / Altera EP2A40F33C-9 is a member of the APEX II family of programmable logic devices, providing up to 1.6 million equivalent system gates and 65 Kbytes of embedded RAM in a 672-ball FineLine BGA (F33) package with commercial temperature grade and -9 speed grade. According to manufacturer naming convention decoded by multiple distributors, the part is built on a 0.15 micrometer CMOS process with multi-core architecture supporting up to 1,690 Kbits of dedicated RAM and 16 high-speed LVDS channels. An FPGA (Field Programmable Gate Array) is a reprogrammable integrated circuit that contains an array of configurable logic blocks (CLBs), programmable interconnect, and embedded memory blocks, all of which can be reconfigured by the designer after manufacturing. FPGAs sit at the boundary between general-purpose processors and ASICs: unlike microcontrollers they execute logic in hardware parallelism, and unlike ASICs they ship as blank silicon that customers customize in minutes rather than months. APEX II was Altera's high-density flagship prior to the Stratix era, targeting ASIC replacement, high-speed DSP datapaths, and bus-interface bridging. Key features of the EP2A40F33C-9 include 1.6 million maximum system gates, 65 Kbytes of embedded memory, four Delay-Locked Loops (PLLs) for clock conditioning, multi-voltage I/O support, and embedded LVDS channels capable of gigabit-per-second signaling. The F33 FineLine BGA package provides 672 balls on a 1.27 mm pitch, supporting dense board layouts and high pin-count signaling for parallel buses and memory interfaces. The -9 speed grade sits in the middle of the APEX II speed binning, balancing performance and power for cost-sensitive applications. The architecture is built on a Look-Up Table (LUT)-based fabric combined with dedicated multiplier, memory, and I/O elements. Embedded CAM blocks enable content-addressable memory applications such as network lookups and translation tables. The device supports hot-socketing, in-system programmability via JTAG, and configuration via serial PROM or parallel flash, allowing field updates without removing the device from its socket. Typical applications include ASIC prototyping and replacement, telecommunications switching equipment, high-speed serial protocol bridging, image and video processing pipelines, and military/aerospace control systems where legacy Altera design IP must remain supported. The wide I/O count makes it well suited to parallel processor glue logic and backplane interface bridging. When designing with this device, pay attention to the FineLine BGA breakout: 1.27 mm pitch requires at least 4-layer PCB stackup with microvias or HDI technology. The APEX II architecture requires the Quartus II (or MAX+PLUS II legacy) design software; verify tool support status before committing the design to a new schematic, since APEX II was classified NRND/EOL several years ago and many newer tool versions no longer target it.

EP2A40F33I-7 - APEX II FPGA 33FBGA, Intel / Altera, Industrial
The Intel / Altera EP2A40F33I-7 is a high-density APEX II family Field Programmable Gate Array (FPGA) housed in a 33-ball Fine-pitch Ball Grid Array (FBGA) package, rated for industrial temperature range. It belongs to the APEX II programmable logic device family designed for high-performance, system-on-chip integration with embedded logic, memory, and high-speed interconnect. An FPGA (Field Programmable Gate Array) is a type of programmable logic device containing an array of configurable logic blocks (CLBs), embedded memory, DSP blocks, and programmable I/O that can be reconfigured by the designer after manufacturing. In the broader taxonomy, FPGAs sit under programmable logic -> logic ICs -> integrated circuits, offering ASIC-class performance with NRE-free development cycles. The APEX II family is positioned for high-density data-path and communication designs, sitting between earlier APEX 20K and later Stratix families in Altera's roadmap. Key features of the EP2A40F33I-7 include peak reflow compatibility up to 220 C (Pb-free reflow profile), Moisture Sensitivity Level 3 (MSL3) per JEDEC J-STD-020, and an industrial temperature grade (-40 C to +85 C ambient). The 33-ball FBGA package is optimized for compact board layouts while still supporting high I/O density. The device is part of Altera's APEX II family - the '40' suffix indicates the high-density member of that generation with the largest logic capacity in its class. Technically, the APEX II family combines Look-Up Table (LUT)-based logic with embedded system blocks and high-speed interconnect, supporting megafunction IP cores for memory controllers, DSP pipelines, and bus interfaces. Designers typically use the Quartus design suite to synthesize, place-and-route, and program the device via JTAG or configuration flash. The 33-ball FBGA offers the smallest footprint in the APEX II lineup while preserving the family's high-speed I/O capabilities. Typical applications include telecommunications infrastructure (line cards, backplanes), high-speed serial protocol bridging, industrial control and factory automation backplanes, ASIC prototyping, and test & measurement instrumentation. The industrial temperature grade supports deployment in uncontrolled thermal environments without derating. When designing with this part, note that MSL3 requires floor-life management: bake-out or re-bag with desiccant if exposed beyond 168 hours. Use a Pb-free reflow profile peaking at 220 C and ensure BGA pad design follows the IPC-7351 nominal-density land pattern for 0.8 mm-pitch FBGA to avoid joint defects.
