EP2A40B724C7ES - APEX II 1.5M Gates 562MHz FPGA | Intel | 724-FCBGA

The Intel (formerly Altera) EP2A40B724C7ES is a member of the APEX II family of FPGAs, providing 1.5 million system gates, 38,400 logic elements, and a 562 MHz internal performance in a 724-pin FCBGA package. It is fabricated on a 0.15 µm process and operates from a 1.5 V core supply, designed for high-density, high-performance programmable logic applications. What is an FPGA? A Field-Programmable Gate Array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that engineers can program after manufacture. FPGAs sit in the broader hierarchy of programmable logic devices (PLD), which also includes CPLDs (Complex Programmable Logic Devices). Within Intel's portfolio, the APEX II family sits between the older APEX 20K and later Stratix families, targeting high-gate-count designs with embedded memory and a MultiCore architecture for parallel processing. Key features of the EP2A40B724C7ES include 38,400 logic cells, embedded system blocks (ESBs) for RAM/ROM, 4 Phase-Locked Loops (PLLs) for clock management, and LVTTL/LVCMOS/PCI I/O standards. The 724-ball Fine-pitch Chip-Scale BGA (FCBGA) package provides high I/O density and excellent signal integrity for multi-million-gate designs operating in the 100-200 MHz range. The 0.15 µm process and dedicated MultiCore routing fabric deliver deterministic timing closure for high-performance datapath and bus-interface applications. The architecture uses a MultiCore fabric of LUTs, product-term logic, and embedded memory that supports distributed and block RAM modes. With 562 MHz internal performance, the EP2A40B724C7ES targets designs that previously required ASIC-class integration at the cost of mask charges and NRE. The 1.5 V core supply reduces power versus 2.5 V FPGAs of equivalent gate count, and the 724-pin FCBGA supports up to 4 PLLs and high-speed LVDS I/O for parallel bus and memory interfaces. Typical applications include telecommunications line cards, ASIC prototyping, DSP co-processing, custom peripheral controllers, high-speed bus bridging (PCI, PCI-X, DDR memory interfaces), and broadcast-video processing. APEX II is particularly well suited for pre-silicon ASIC prototyping where gate count, embedded memory, and deterministic timing closure are critical. When designing with this FPGA, ensure proper power-plane integrity for the 1.5 V core rail and decoupling per the APEX II pin connection guidelines. The 724-FCBGA package requires PCB layer stack-up with controlled-impedance routing; signal-integrity simulation is recommended above 100 MHz. This page synthesizes distributor inventory, drop-in APEX II alternatives, and practical design notes not found in the manufacturer datasheet alone, giving engineers a single reference for sourcing and substitution.

EP2A40B724C7N - APEX II 1.5M Gates FPGA, 724-Pin FCBGA | Intel/Altera

The Intel (formerly Altera) EP2A40B724C7N is a high-density APEX II family Field-Programmable Gate Array (FPGA) delivering 1.5 million system gates, 38,400 logic elements, and 562 MHz maximum internal performance on a 0.15 um CMOS process. The device is housed in a 724-pin Fine-pitch BGA (FCBGA) package with 536 user I/O lines and operates from a 1.5 V core supply (1.425 V to 1.575 V). According to the verified distributor data, propagation delay is rated at 1.55 ns with a JESD-30 code of S-PBGA-B724, and the commercial temperature grade spans 0 C to 85 C. An FPGA is a reprogrammable digital integrated circuit whose logic function is defined by user configuration rather than fixed mask interconnect. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs) and are differentiated from CPLDs by their register-rich, fine-grained architecture, on-chip block RAM, dedicated DSP/multiplier blocks, and high-speed transceivers. The APEX II family targeted high-performance, gate-intensive designs including networking line cards, telecom bridges, and ASIC prototyping. Key specifications of the EP2A40B724C7N include 1.5M system gates, 38,400 logic cells, 536 user I/O, 1.5 V core supply, 0.15 um CMOS process, 1.55 ns propagation delay, 562 MHz internal performance, and 724-pin FCBGA packaging. The MACROCELL output function and LOADABLE PLD classification confirm its APEX II family membership, with embedded system blocks (ESBs) providing RAM and ROM functions configurable per design. Architecturally, the APEX II device combines lookup-table-based logic elements (LEs) with embedded system blocks that operate as dual-port RAM or content-addressable memory. The 1.5 V VCCINT supply and 0.15 um process were state of the art when the APEX II family launched, enabling lower dynamic power than earlier 0.18 um APEX devices while sustaining the family's high I/O count. The 724-pin FCBGA package supports the 536 I/O lines plus configuration, clock, and power pins. Typical applications include high-speed networking line cards, telecommunications bridges, ASIC prototyping and emulation, high-performance DSP pipelines, and legacy industrial control platforms. The 1.5M gates and 536 I/O lines make the EP2A40B724C7N well suited to designs that must aggregate multiple buses or implement wide datapaths. When designing with this legacy device, engineers should verify that the Altera Quartus II design tool (version supporting APEX II) is available and that any required IP cores have not been removed from current Quartus releases. The 0.15 um process and 1.5 V core imply careful power-plane design and decoupling, and the BGA package requires X-ray inspection during assembly. This page synthesizes distributor pricing, lifecycle status, and drop-in alternative notes that are not collated on any single manufacturer or distributor page, providing a consolidated reference for engineers maintaining or sourcing APEX II designs.

EP2A40B724C8 - APEX II FPGA 1.5M Gates 540 I/O 724-FCBGA

The Intel (formerly Altera) EP2A40B724C8 is a member of the APEX II field-programmable gate array (FPGA) family, providing approximately 1.5 million system gates, 38,400 logic elements (cells), and 655,360 bits of embedded RAM in a 724-ball Fine-pitch Chip-Scale Ball Grid Array (FCBGA). It operates from a 1.5 V core supply (1.425 V to 1.575 V) and supports up to 540 user I/Os, fabricated on a 0.15-µm all-layer copper process with up to eight metal layers. What is an FPGA? A Field-Programmable Gate Array (FPGA) is a programmable logic device (PLD) semiconductor whose logic fabric, routing, and I/O behaviour are defined by a user-supplied configuration bitstream after manufacture. FPGAs sit at the top of the programmable logic hierarchy (PAL/CPLD -> FPGA -> SoC FPGA) and are widely used to implement glue logic, custom datapaths, and high-throughput parallel signal processing. The APEX II family in particular combines fine-grained Look-Up Tables (LUTs) with embedded memory blocks and supports high-speed serial interfaces up to 1 Gbps, including True-LVDS, LVPECL, PCML, and HyperTransport signalling. Key features include 38400 logic cells, 540 user I/Os, 655360 bits of RAM, embedded True-LVDS I/O supporting 1 Gbps data rates, and high-speed LVPECL/PCML/HyperTransport support. The device also supports up to eight layers of copper interconnect, enabling high-fanout designs with predictable timing closure on long combinational paths. The EP2A40B724C8 is built on a 0.15 µm eight-layer copper CMOS process with a 1.5 V core. Its embedded memory blocks and dedicated high-speed I/O channels allow direct connection to DDR-style external memories and backplane serial links without an external PHY, which simplifies board layout in telecom and high-end industrial designs. Typical applications include telecommunications line cards, high-speed serial backplanes, ASIC prototyping, DSP co-processing, and high-density glue logic in networking equipment. The high I/O count also makes it suitable for industrial imaging and test-and-measurement instrumentation front-ends. When designing with the EP2A40B724C8, plan thermal dissipation carefully: at high toggle rates the 724-FCBGA can dissipate several watts, so a multi-layer PCB with thermal vias under the die is required for reliable operation. Power sequencing between the 1.5 V core and 3.3 V I/O rails must also be respected to avoid latch-up. This page synthesizes distributor pricing, drop-in alternatives from the same APEX II family, and practical design notes not found in the manufacturer datasheet, providing engineers with a complete view of the part's lifecycle position, pin-compatible substitutes, and key electrical parameters.

The Altera (Intel) EP2A40B724C9 is a high-density member of the APEX II Field Programmable Gate Array family, delivering 38,400 logic elements, 655,360 bits of embedded RAM, and 540 user I/Os in a 724-ball FineLine BGA (FCBGA) package measuring 35x35 mm. It is one of the largest devices in the APEX II family and is engineered for system-on-chip designs that require very wide parallel buses and substantial on-chip memory buffering. What is an FPGA? A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable routing, and dedicated hardware resources such as block RAM, DSP blocks, PLLs, and high-speed transceivers. FPGAs belong to the broader category of programmable logic devices (PLDs), which also includes CPLDs. Within the IC hierarchy, an FPGA sits between a microcontroller (sequential, software-driven) and a custom ASIC (fixed-function, masked): FPGAs deliver hardware-level parallelism with the flexibility of in-system reconfiguration. Key features of the EP2A40B724C9 include up to 1,600 Kbits of True Dual-Port RAM, MultiVolt I/O support for interfacing with 1.5V, 1.8V, 2.5V, and 3.3V logic families, and a core voltage of 1.5V (operating supply 1.425V to 1.575V). The 540 user I/O count makes it well-suited for memory-rich applications, ASIC prototyping, and parallel DSP pipelines. The APEX II architecture combines Look-Up Table (LUT)-based logic with embedded memory blocks, supporting both single-port and true dual-port RAM.

EP2A40B724C9ES

EP2A40B724C9ES - 1.5M-Gate 366MHz FPGA | Intel

Intel EP2A40B724C9ES is an APEX II family field-programmable gate array with 1.5 million gates, 38,400 logic cells, a 366 MHz operating-frequency rating, 0.15 µm process technology, a 1.5 V supply, and a 724-pin FCBGA package. The part belongs to a programmable-logic architecture designed to implement customizable digital systems through user-defined configuration rather than fixed application-specific logic. Its combination of high logic density and broad package capacity supports datapaths, control functions, interfaces, and multi-function digital processing on one programmable device. A field-programmable gate array, or FPGA, is a semiconductor device containing configurable logic blocks, routing resources, and programmable input/output structures. The FPGA hierarchy proceeds from configurable logic block to programmable logic device, programmable logic array, and ultimately to an integrated circuit used in digital system design. Unlike a fixed ASIC, an FPGA can be configured after manufacturing, making it suitable for evolving requirements, prototyping, production equipment, and applications where field updates are valuable. Intel represents the MPN in verified results as both an Altera-origin APEX II FPGA and an Intel programmable-logic product. The headline characteristics are 1.5 million gates, 38,400 cells, and a 366 MHz rating. The 1.5 million-gate figure indicates aggregate programmable logic capacity, while the 38,400-cell count provides a more direct device-resource indicator. The 0.15 µm process technology identifies the fabrication generation used for the APEX II family, and the 1.5 V supply indicates the part's core electrical operating point. The 724-pin FCBGA package supplies the high pin count required by a large programmable device and a dense surface-mount interconnection scheme. Within an FPGA architecture, configurable logic resources implement combinational and sequential functions, while programmable interconnects connect those functions and the I/O subsystem. Design software maps a hardware description or supported design entry into the device's configuration resources. Performance depends on the implemented logic, interconnect utilization, I/O timing, and power conditions; therefore, the 366 MHz figure is best interpreted as a published device characteristic rather than a guarantee for every possible design. Typical uses include communications equipment, industrial automation, test and measurement systems, and embedded digital-control platforms. The APEX II family can be appropriate when a design needs programmable interfaces, custom state machines, protocol handling, or parallel digital processing. The 1.5 million-gate and 38,400-cell resources provide substantial capacity for systems that would otherwise require multiple fixed-function components. Designers should verify configuration hardware, supported software versions, I/O assignments, clocking, power sequencing, thermal performance, and signal integrity against the manufacturer documentation before release. The legacy APEX II platform may impose migration and obsolescence-management considerations; use current authorized Intel support channels and the manufacturer datasheet before starting a new design. This page combines the verified web specification record, sourcing context, package information, and cautious engineering guidance to help engineers assess EP2A40B724C9ES without treating unverified values as confirmed facts.

An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that allows engineers to implement arbitrary digital logic through a sea of configurable logic blocks, programmable interconnect, and I/O cells. Within the broader taxonomy, FPGAs sit under programmable logic devices -> logic ICs -> integrated circuits -> semiconductors, complementing CPLDs (which target simpler glue logic) and ASICs (which are application-specific but not field-reprogrammable). The APEX II family specifically targets high-performance data-path, telecommunications, and DSP designs that require on-chip RAM and multipliers. Key features of the EP2A40B724C9N include 38,400 logic cells, a maximum propagation delay of 2.05 ns, 0.15 µm process geometry, 1.5 V core supply, and 536 user I/O lines for high-bandwidth external interfacing. The 724-ball FCBGA package uses a 1.270 mm ball pitch and supports surface-mount assembly on standard FR-4 PCB substrates with controlled-impedance routing. The device also integrates MultiVolt I/O support for interfacing with mixed-voltage rails common in telecom backplane designs. The APEX II architecture combines a Logic Array Block (LAB) fabric with Embedded System Blocks that provide true dual-port RAM, FIFO buffers, and dedicated multiplier blocks. This makes the EP2A40B724C9N particularly well-suited for high-throughput signal-processing pipelines where parallel arithmetic paths need simultaneous data storage and compute resources. The 366 MHz internal frequency enables 32-bit datapath designs in the 100-200 MHz operating range typical of communications infrastructure. Typical applications include telecommunications line-card processing, high-speed networking ASIC prototyping, DSP accelerator functions, and baseband signal processing. The wide I/O count (536 user I/O) and high pin density also make the device suitable for custom interface bridging and protocol conversion in industrial embedded systems. When designing with this FPGA, engineers must provide adequate decoupling on all VCCINT and VCCIO rails, follow Intel/Altera's Quartus II place-and-route tool flow, and respect the device's junction temperature envelope under industrial operating conditions. Because the APEX II family is a mature node, second-source supply and long-term availability should be verified before committing to new designs.

EP2A40B724I-8

EP2A40B724I-8 - APEX II FPGA, 38,400 LEs, 724-BGA | Altera

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. This page synthesizes sourced distributor inventory, APEX II family context, and drop-in family variants not consolidated in any single manufacturer datasheet, providing engineers with a single decision view for legacy redesign work.

EP2A40B724I-9

EP2A40B724I-9 - APEX II 40K LE FPGA, 724-BGA, Industrial | Intel

The Intel (formerly Altera) EP2A40B724I-9 is a member of the APEX II family of Field Programmable Gate Arrays (FPGAs), delivering approximately 40,000 logic elements, 655,360 bits of embedded SRAM, and 38400 logic cells in a 724-ball FineLine BGA package. 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.

The device combines Look-Up Table (LUT)-based logic, embedded system blocks (ESBs) for memory and specialized functions, and high-speed interconnect, targeting ASIC-replacement designs with hundreds of thousands of usable gates. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that engineers configure after manufacturing to implement arbitrary digital logic. Within the broader taxonomy, FPGAs belong to programmable logic ICs -> logic ICs -> integrated circuits -> semiconductors. APEX II is positioned within Altera's high-density, MultiCore architecture family; it sits above APEX 20K and below Stratix in the legacy Altera roadmap and is widely understood by engineers familiar with CPLD and FPGA design flows. The APEX II family also introduced built-in LVDS and high-speed SERDES-capable I/O, separating it from earlier FLEX/Acex devices. Key differentiating features of the EP2A40B724I7 include 1.5 M system gates, 38,400 logic cells, 562 MHz performance, an industrial temperature grade (-40 C to +100 C minimum), and a 724-ball FCBGA package. The combination of high logic density and embedded memory/ESB blocks enables on-chip implementation of FIFOs, dual-port RAM, and CAM structures without external components, simplifying board layout and BOM. 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 architecture combines MultiCore interconnect routing with dedicated carry chains and cascade chains, enabling efficient implementation of wide arithmetic functions, state machines, and bus bridges. Multi-voltage I/O lets portions of the device interface with 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V buses simultaneously without external translators. Typical applications include telecommunications line cards, high-speed data routers, PCI bridge and bridge/repeater designs, asynchronous transfer mode (ATM) switching fabrics, high-performance DSP pipelines, and graphics/AGP interfaces. The 724-pin FCBGA package supports the large I/O count required for these bus-intensive designs. When designing with this device, use the Quartus II design software (legacy support) and respect the LVTTL/LVCMOS drive-strength settings to keep SSO (Simultaneously Switching Outputs) noise within the IBIS-modeled limits. Decoupling requires low-impedance power planes with bulk, mid-frequency, and high-frequency ceramic capacitors distributed across the FCBGA footprint.

The Altera (Intel) EP2A40B724I8 is a high-density APEX II Field Programmable Gate Array (FPGA) delivering 40,000 logic elements, 655,360 bits of embedded RAM, and 540 user I/O pins in a 724-ball Fine-pitch Chip-Scale BGA (FCBGA) package measuring 35x35 mm. As part of the APEX II family, the EP2A40B724I8 combines Look-Up Table (LUT)-based logic with embedded memory blocks and is fabricated on a 0.18 µm CMOS process. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that allows designers to configure digital logic, memory blocks, and I/O behavior after manufacturing. Within the broader semiconductor hierarchy, FPGAs belong to the digital logic IC family, sitting between ASICs (application-specific, fixed-function) and general-purpose processors. FPGAs trade raw clock speed and per-unit cost for design flexibility, rapid prototyping, and parallel hardware execution - making them ideal for high-throughput data-path and interface-bridging applications. The EP2A40B724I8 integrates 38400 logic elements (LEs) distributed across four MegaLAB structures, each containing embedded system blocks (ESBs) that can be configured as RAM, ROM, or content-addressable memory. The device supports LVTTL, LVCMOS, SSTL, and HSTL I/O standards with multi-voltage operation (1.5 V, 1.8 V, 2.5 V, 3.3 V) on its 540 user I/O pins. Each LE contains a 4-input LUT, a programmable register, and dedicated carry and cascade chains for high-speed arithmetic and wide fan-in functions. Architecturally, APEX II uses a MultiCore architecture with embedded memory and dedicated high-speed interconnect (DirectDrive, MultiTrack). The 1.425 V to 1.575 V core supply and 540 I/O make this device suitable for high-bandwidth telecommunications, video processing, and parallel DSP functions where multiple clock domains and large amounts of on-chip buffering are required. Typical applications include high-speed data acquisition front-ends, ATM backbone switches, base-station channel cards, HDTV video processing, and protocol-bridging ASIC prototyping. Designers migrating from fixed ASICs use the EP2A40B724I8 to validate RTL early in the design cycle and reduce NRE risk. When designing with this device, pay particular attention to power-rail sequencing (core VCCINT before VCCIO), decoupling (low-ESL ceramics on every VCC/VSS pair), and the high-pin-count FCBGA land pattern which requires microvia PCB stack-ups and assembly under ENIG or immersion-silver surface finish for reliable solder joint formation.

Operating from a 1.5 V core supply with an internal propagation delay of 1.7-1.78 ns, the device supports up to 536 user I/O and an internal clock frequency rated up to 376 MHz, making it one of the largest members of the early-2000s APEX II line. An FPGA (Field Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), embedded memory, DSP blocks, and programmable I/O cells interconnected by a hierarchical routing fabric. After manufacturing, the device is customized by loading a configuration bitstream that sets each switch matrix and lookup-table content. APEX II devices in particular are built on a MultiCore architecture that combines fine-grained logic with embedded ESB (Embedded System Blocks) for RAM, ROM, and CAM functions, allowing single-chip implementation of complex glue logic, bus interfaces, and DSP datapaths. The hierarchy is: FPGA -> programmable logic device (PLD) -> loadable PLD -> logic IC -> integrated circuit -> semiconductor. Key features of the EP2A40B724I8N include 540 LABs/ESBs, 655,360 bits of embedded memory, 38,400 logic cells, 16 macrocells per LAB cluster (PLA-style grouping), a propagation delay of 1.7-1.78 ns, and 536 maximum user I/O. The device supports in-system programmability via the IEEE 1149.1 boundary-scan interface plus dedicated configuration ports (PS, AS, JTAG), and includes on-chip PLLs for clock multiplication and deskew. Its CMOS technology node and 1.5 V core make it suitable for high-density designs targeting telecom backplanes, video processing, and high-speed serial interfacing.

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.

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.

EP2A40F1020C7 - APEX II FPGA 1.5M Gates 1020-BGA | Altera

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.

EP2A40F1020C7ES

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.

EP2A40F1020C7N

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.

EP2A40F1020C8 - APEX II 1.5M Gates FPGA, 1020-FBGA | Intel / Altera

The Intel (formerly Altera) EP2A40F1020C8 is a member of the APEX II family of programmable logic devices (PLDs), delivering approximately 1.5 million system gates and 38,400 logic cells in a 1020-pin FineLine Ball-Grid Array (FC-FBGA) package measuring 33 x 33 mm with a 1.0 mm ball pitch. 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.
