EP2A40F672C8N - APEX II 1.5M Gates FPGA | Intel | 672-BGA

The Intel (formerly Altera) EP2A40F672C8N is a high-density programmable logic device (PLD) from the APEX II family, built on a 0.15 µm all-layer copper CMOS process with up to eight metal layers. It delivers 1.5M system gates, 38,400 logic cells, and operates at up to 376 MHz internal frequency. The device is housed in a 672-ball FineLine BGA (FC-FBGA) measuring 27 x 27 mm with a 1.0 mm ball pitch, providing 492 user I/Os and supporting 1 Gbps LVDS performance. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement arbitrary digital logic. APEX II devices sit in the programmable logic hierarchy as follows: PLD -> CPLD/FPGA -> high-density FPGA with embedded memory and I/O. The APEX II family specifically targets high-performance datapath, communications, and ASIC-replacement designs where dense logic and high I/O count are required. Key features of the EP2A40F672C8N include 1.5 M system gates, 38,400 logic elements, 4 embedded PLLs for clock synthesis, dedicated high-speed LVDS channels supporting 1 Gbps data rates, a 1.5 V nominal core supply (1.425 V to 1.575 V range), and 492 user I/Os. The propagation delay is rated at 1.55 ns for internal logic, and the device supports in-system programming via the JTAG boundary-scan interface per IEEE 1149.1. Architecturally, the EP2A40F672C8N uses a MultiCore structure of Look-up Tables (LUTs), embedded array blocks (EABs) for memory and DSP functions, and FastTrack interconnect routing. The 0.15 µm copper process enables high transistor density while maintaining low dynamic power. Built-in PLLs simplify clock tree synthesis, and LVDS support is critical for high-speed parallel interfaces such as SPI-4.2, Rapid I/O, and POS-PHY. Typical applications include telecommunications switching and routing equipment, ASIC prototyping and emulation, high-speed datapath processing, digital signal processing front-ends, and high-density glue-logic replacement. With 492 user I/Os, the device is well-suited for systems that require wide memory buses (DDR SDRAM controllers) or multiple parallel channel interfaces. When designing with this device, ensure the 1.5 V core supply is generated by a low-noise regulator such as the TPS7A4701 to meet the VCCINT tolerance. The 672-ball BGA package requires a multilayer PCB (typically 6 or more layers) with controlled-impedance routing for LVDS signals and matched-length traces for clocks.

The Altera (Intel) EP2A40F672C9 is a member of the APEX II programmable logic device (PLD) family, fabricated on a 0.15-µm all-layer copper-metal process that supports up to eight layers of metal interconnect. The device integrates 1.5 million system gates with 38,400 logic elements, 492 user I/Os, and a 1.5 V core supply, housed in a 672-ball FineLine BGA package measuring 27 mm × 27 mm with a 1 mm ball pitch. An FPGA (Field-Programmable Gate Array) is a programmable logic device that lets engineers implement arbitrary digital logic through SRAM-based configuration cells. FPGAs sit hierarchically above CPLDs and below ASICs in the programmable logic taxonomy, and the APEX II family is positioned as a high-density, embedded-multiplier-rich variant that bridged telecom, networking, and DSP prototyping workloads in the early-2000s generation of programmable logic. Key features of the EP2A40F672C9 include support for 1 Gbps True-LVDS, LVPECL, PCML, and HyperTransport I/O standards, embedded memory blocks, embedded multipliers, and a maximum toggle performance in the 366 MHz range. The FineLine BGA-672 footprint exposes 492 user I/O pins, providing the channel density required for parallel bus interfaces and high-speed serial links. Operating temperature is graded for commercial use from 0 °C to 85 °C. Architecturally, the APEX II device combines LAB (Logic Array Block) structures with embedded system blocks (ESBs) for dual-port RAM and ROM, and dedicated multiplier blocks optimized for DSP filter pipelines. The 0.15-µm process delivers high logic density while the 1.5 V core minimizes dynamic power for the gate count, and the eight-metal stackup enables efficient routing of wide buses. Typical applications include telecom line-card prototyping, high-speed serial backplane bridging, DSP co-processing, bus-width conversion glue logic, and ASIC prototyping. The 672-ball BGA package and 1.5 V core also suit legacy designs migrated from earlier APEX 20K families that need additional gate capacity and faster I/O standards. When designing with this device, plan power sequencing for the 1.5 V core and I/O bank supplies separately, and follow Altera's BGA layout guidelines for 1 mm-pitch FineLine packages to ensure reliable solder joint integrity through thermal cycling. This page synthesizes distributor pricing, verified same-package alternatives in the APEX II family, and practical design notes not found in the original APEX II datasheet (DS-APEXII-3.0). It is intended as an engineering reference for sourcing, replacement, and lifecycle planning.

EP2A40F672C9ES

EP2A40F672C9ES - APEX II FPGA 1.5M Gates 672-FBGA | Altera

The Altera (now Intel) EP2A40F672C9ES is a member of the APEX II family of programmable logic devices, delivering 1,500,000 system gates with 38,400 logic elements in a 672-pin Fine-pitch Chip-scale Ball Grid Array (FC-FBGA) package. Built on a 0.15 μm CMOS process and operating from a 1.5 V core supply, the device is rated for speeds up to 366 MHz internal operation with a -9 speed grade marking. A Field-Programmable Gate Array (FPGA) is a reconfigurable semiconductor device built from an array of programmable logic blocks, interconnect, and I/O cells that designers can configure after manufacturing to implement custom digital functions. Within the wider hierarchy, an FPGA is a type of Programmable Logic Device (PLD), which itself falls under digital logic integrated circuits. The APEX II architecture extends this concept with embedded MultiCore interconnect and embedded system blocks (ESBs) that double as RAM, ROM, or CAM memory, making the device suitable for high-density data-path, telecommunications, and DSP-intensive applications. Key features of the EP2A40F672C9ES include 492 user I/O pins supporting multiple I/O standards (LVTTL, LVCMOS, PCI, SSTL, HSTL, GTL+), 1.5 M system gates, 38,400 logic cells, dedicated multiplier/clock circuitry, and JTAG-based IEEE 1149.1 boundary-scan support. The device supports in-system programmability via the passive serial (PS), passive parallel synchronous (PPS), passive parallel asynchronous (PPA), JTAG, and Altera Fast Passive Parallel (FPP) configuration modes through a serial configuration device such as the EPC2 or EPC8. From an architectural standpoint, the APEX II family combines Look-Up Table (LUT) logic with embedded array blocks, giving designers a flexible trade-off between fine-grained logic and block-level memory. The MultiCore interconnect uses continuous, predictable routing across rows, columns, and embedded blocks, which simplifies timing closure on dense 672-pin designs. The 1.5 V core voltage reduces power consumption versus older 2.5 V families such as APEX 20K, while the -9 speed grade places this part at the high-performance end of the family. Typical applications include high-speed telecommunication backplanes, ATM packet processing, SONET/SDH framer designs, custom DSP pipelines, and PCI bus interfaces. The 672-pin FC-FBGA package provides high signal density for board-constrained designs where 492 I/O channels must be routed out of a single chip. When designing with this device, note that the APEX II family has been classified as legacy/not recommended for new designs. Engineers should verify long-term supply availability with the manufacturer before committing to a new production program, and consider Cyclone III/IV/10 or newer families for greenfield designs while keeping the APEX II for legacy upgrades.

EP2A40F672C9N

EP2A40F672C9N - APEX II 1.5M Gates FPGA, BGA-672 | Intel

The Intel EP2A40F672C9N is a high-density FPGA from the APEX II family, delivering 1.5 million system gates and 38,400 logic elements in a 672-pin FC-FBGA (Fine-pitch Chip-Scale Ball Grid Array) package with 27 x 27 mm body and 1.0 mm ball pitch. An FPGA (Field Programmable Gate Array) is a programmable logic device that combines the architectural flexibility of a gate array with the design-turnaround advantage of in-system programmability. Within the wider semiconductor taxonomy, FPGAs sit between fixed-function ASICs and microcontrollers: they offer hardware-level parallelism and deterministic timing, while remaining fully re-programmable. The APEX II family is a second-generation APEX architecture using a 0.15 µm all-layer copper interconnect process with up to eight metal layers, supporting 1 Gbps LVDS I/O performance. Key specifications include 492 user I/O pins, 1.55 ns propagation delay, 366 MHz internal operation, 1.5 V core supply, and an embedded system block (ESB) that delivers up to 1.125 Mbits of dual-port RAM. The Look-up Table (LUT)-based logic elements include carry-chain and register-chain resources for arithmetic-intensive datapaths. The 'C9' speed grade places this part in the mid-speed bin of the family, with '-9' corresponding to approximately 1.5 ns pin-to-pin delay. The APEX II architecture combines four types of structures: Logic Array Blocks (LABs) for fine-grained logic, ESBs for memory and arithmetic, MegaLAB structures that group LABs and ESBs, and FastTrack interconnect for predictable row/column routing. This hierarchy makes the device well-suited to system-on-chip integration where a mix of glue logic, FIFOs, register files, and DSP pipelines must coexist. Typical applications include high-speed telecommunications backplanes, parallel DSP engines for video processing, custom protocol bridges between ASICs, and high-throughput data acquisition systems. The 492 available I/Os make it particularly attractive for bus-intensive designs such as DDR memory controllers, parallel pixel processing, and multi-port network interfaces. When designing with this part, pay close attention to power-plane decoupling: at 366 MHz with 38K logic elements, dynamic current peaks can exceed 3 A. Place at least 16 low-ESR 0.1 µF capacitors directly beneath the BGA footprint, plus four bulk 22 µF capacitors near the corners. Signal-integrity simulations should be performed on all LVDS and clock nets before layout sign-off, since FastTrack routing delay varies with fan-out.

EP2A40F672I-9

EP2A40F672I-9 - APEX II FPGA, 1.5M Gates, 672-BGA | Intel

The Intel EP2A40F672I-9 is a high-density member of the APEX II FPGA family delivering 1.5 million system gates and 38,400 logic elements in a 672-pin FC-FBGA package, manufactured on a 0.15 µm CMOS process. The APEX II family combined the MultiCore architecture with on-chip CAM, dual-port RAM, and high-speed True-LVDS signaling to target high-bandwidth communications, DSP, and datapath-intensive designs. The EP2A40F672I-9 is specified for industrial temperature operation and is built around a 1.5 V core supply with hot-socketing tolerant I/O. An FPGA (Field Programmable Gate Array) is a programmable logic device whose logic blocks, interconnect, and I/O can be reconfigured after manufacturing, providing ASIC-like density and performance with NRE-free prototyping. FPGAs sit hierarchically between general-purpose CPUs/DSPs and fixed-function ASICs: they deliver higher throughput than a processor for parallel tasks, and faster time-to-market than a mask-programmed ASIC. APEX II parts further integrate dedicated CAM blocks and LVDS channels that simplify communications and datapath designs. Key features of the EP2A40F672I-9 include 38,400 logic elements, embedded CAM support, dual-port RAM blocks, True-LVDS I/O, and an industrial operating range. The 672-ball FC-FBGA package provides controlled-impedance routing for high-speed interfaces, while 0.15 µm process technology balances density and static power. The device operates from a 1.5 V core supply with separate VCCIO banks supporting mixed-voltage I/O. Hot-socketing capability allows the device to be inserted into a live backplane without damage or data corruption. Architecturally, APEX II devices pair four-input LUT-based logic elements with embedded system blocks (ESBs) that can be configured as dual-port SRAM, single-port SRAM, ROM, or CAM. True-LVDS receivers and transmitters on dedicated channels deliver data rates up to several hundred Mbps per channel, suitable for LVDS bridges and parallel backplanes. The MultiCore interconnect with DirectDrive technology ensures predictable timing for high-fanout nets across the 672-pin FC-FBGA package. Typical applications include high-speed communications interfaces, ASIC prototyping, datapath co-processing, and DSP accelerator designs. The combination of CAM, dual-port RAM, and LVDS makes APEX II particularly attractive for ATM switching, protocol translation, and PCI-to-PCI bridges. The industrial temperature grade also supports telecom line cards and industrial control backplanes. When designing with the EP2A40F672I-9, pay close attention to power sequencing: VCCINT must reach stable 1.5 V before VCCIO is applied, and vice versa on power-down. The device draws significant inrush current during configuration - use the Altera MAX series (EPM7xxx) or discrete supervisory circuitry to hold the FPGA in reset until supplies stabilize. Decoupling requires at least 22 µF bulk + 0.1 µF + 0.001 µF per power pin group. This page consolidates APEX II datasheet facts, intel/Altera ordering information, and pin-compatible same-family alternatives in a single reference - including 672-pin FC-FBGA drop-in variants and speed-grade siblings - to help procurement and hardware engineers validate EP2A40F672I-9 sourcing decisions.

Manufactured on a 0.15 µm CMOS process, this device operates from a 1.5 V core supply and is specified for the industrial temperature range (-40 °C to +85 °C) as indicated by the 'I' speed-grade suffix. The '7' suffix denotes a 7-device speed grade pin-compatible with other speed grades in the EP2A40F672 family. An FPGA is a reprogrammable semiconductor device whose logic function is defined by a user-supplied configuration bitstream rather than by the silicon vendor. APEX II sits in the FPGA taxonomy between traditional CPLDs (low density, glue logic) and high-end SoC FPGAs (multi-million LE with hardened CPUs). Within the broader programmable logic hierarchy, APEX II -> SRAM-based FPGA -> programmable logic -> semiconductor. Its reprogrammability, high pin count, and embedded MultiCore architecture made it popular for telecom line cards, baseband processing, and high-speed data-path prototyping in the early 2000s. Key features of the EP2A40F672I7 include embedded MultiCore blocks combining lookup tables and product-term logic, a high-bandwidth MultiCore interconnect fabric, support for multiple I/O standards (LVTTL, LVCMOS, PCI, GTL+, SSTL, HSTL, LVDS), and a configurable JTAG-based configuration port.

Multi-voltage I/O banks permit interfacing to 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic without external level translation. Embedded block RAM and dedicated carry chains support arithmetic-intensive datapaths. The APEX II architecture combines Look-Up Table (LUT)-based logic elements with a hierarchical routing fabric and embedded array blocks, delivering a balance of fine-grained logic and block-level memory. The 0.15 µm process and 1.5 V core supply reduce dynamic power versus the original 0.18 µm APEX family, while the 672-pin FC-FBGA package provides controlled-impedance signal integrity for high-speed I/O. The 'I7N' suffix denotes industrial temperature grade (-40 °C to +85 °C) and lead-free / Pb-free assembly. Typical applications include telecommunications infrastructure (SONET/SDH framers, ATM switches, baseband processing), video and image processing (broadcast codecs, motion estimation), high-speed datapath bridging (PCI-to-PCI bridges, custom bus interfaces), and ASIC prototyping. The 1.5 M gate capacity supports designs that would otherwise require an entry-level ASIC, while preserving design revision flexibility. When designing with this device, plan power sequencing carefully: 1.5 V core must ramp before I/O banks. Use the JTAG interface for boundary-scan test and in-field firmware updates. Decoupling requires at least 22 low-ESR 0.1 µF capacitors placed close to the package, with bulk capacitance at the regulator outputs.

EP2A40F672I8 - APEX II 1.5M Gates 672-FBGA FPGA | Intel / Altera

The Intel (formerly Altera) EP2A40F672I8 is a high-density APEX II family Field-Programmable Gate Array (FPGA) delivering 1.5 million system gates with 38,400 logic cells in a 672-ball Fine-pitch Chip-Scale Ball Grid Array (FC-FBGA) package. The device is fabricated on a 0.15 um process, operates from a 1.5 V core supply, and supports system clock frequencies up to 376 MHz, making it suitable for high-throughput parallel processing designs. The 'I8' speed grade denotes an industrial temperature range with mid-tier performance optimization, and the '672' package code designates the FC-FBGA footprint. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnect, and dedicated hard IP such as block RAM, multipliers, and I/O cells. FPGAs belong to the broader category of programmable logic devices (PLDs), which also include CPLDs and structured ASICs. Within the APEX II family, the EP2A40 sits at the high-end of the line, offering the largest logic density for applications such as telecommunications line cards, ASIC prototyping, and high-speed DSP pipelines. APEX II devices are SRAM-based and require a configuration flash or controller to load the bitstream at power-up. Key differentiating features include 1.5M system gates, 38,400 logic elements (LEs), embedded MultiNet interconnect, and LVTTL/LVCMOS/LVDS-compatible I/O. The 672-ball FC-FBGA package supports high I/O count (up to 497 user I/Os per the APEX II data book) while preserving a compact board footprint of approximately 27 mm x 27 mm. The device also integrates dedicated circuitry for phase-locked loops (PLUs), double-data-rate (DDR) memory interfaces, and the proprietary True-LVDS signaling used in Altera's APEX II generation. Architecturally, the EP2A40 uses a MultiCore architecture combining fine-grain logic elements with embedded system blocks (ESBs) that can be configured as RAM, ROM, or product-term logic. The 0.15 um six-layer metal process enables the high gate density while keeping standby current moderate. Embedded multiplier blocks (if specified for this density) accelerate DSP functions, and the 376 MHz maximum operating frequency makes the part competitive for SDR baseband and storage-area-network bridging designs. Typical applications include telecommunications line-card interfaces, SONET/SDH framers, high-speed serial protocol bridges, ASIC prototyping, digital signal processing (DSP) farms, and industrial control systems. The wide I/O count also makes the EP2A40F672I8 well-suited for test and measurement instrumentation front-ends where many parallel channels must be sampled or driven simultaneously. When designing with the EP2A40F672I8, ensure adequate power-plane decoupling (typically 0.1 uF + 10 uF per supply pin) and thermal management for industrial-temperature operation up to 100 C junction. The 1.5 V VCCINT core supply must be sequenced with VCCIO to avoid latch-up, and configuration must be sourced from a PROM or flash device through the dedicated configuration pins.

EP2A40F672I8N - APEX II FPGA 1.5M Gates 672-BGA | Intel / Altera

The Intel (formerly Altera) EP2A40F672I8N is a high-density member of the APEX II FPGA family, integrating 1,500,000 system gates, 38,400 logic elements (cells), and a maximum operating frequency of 376 MHz on a 0.15 micrometer process, supplied from a 1.5 V core rail and packaged in a 672-pin FC-FBGA. An FPGA (Field-Programmable Gate Array) is a programmable logic device that combines the integration density of an ASIC with the flexibility of in-system reconfiguration. Within the broader semiconductor taxonomy, FPGAs sit alongside CPLDs in the programmable logic category, then up through logic ICs to integrated circuits. APEX II specifically targets high-performance, gate-array-class designs where the design captures data-path, DSP and embedded-memory functions on a single fabric. Key features include 38,400 logic cells, 1.5M system gates, 376 MHz maximum internal frequency, on-chip embedded system blocks (ESBs) for memory and arithmetic functions, MultiCore interconnect routing, and LVTTL/LVCMOS/PCI/HSTL/SSTL I/O support. The 672-pin FC-FBGA package is a wire-bond-style fine-pitch BGA designed for high pin-count, moderate-thermal APEX II designs. The device is fabricated on a 0.15 micrometer process and uses a 1.5 V core supply, with separate VCCIO banks that can be set to 3.3 V, 2.5 V, or 1.8 V to match mixed-voltage interfaces. MultiCore routing fabric combined with ESBs allows each logic array block to be paired with dedicated RAM or product-term resources, giving designers a tight balance between register-rich control logic and memory-rich datapath logic. Typical applications include high-speed telecommunications line cards, networking routers, software-defined radio basestation processing, image processing pipelines, and ASIC prototyping. The 1.5M-gate density and 376 MHz performance make it well suited to designs that aggregate multiple channels of DSP, glue-logic plus embedded memory in a single chip. When designing with this device, plan power sequencing so the 1.5 V core rail ramps before any 3.3 V VCCIO bank that drives into the core. Decoupling must combine bulk tantalum or polymer capacitors near the package with high-frequency ceramic capacitors placed adjacent to each bank.

EP2A40F672I9 - APEX II FPGA 1.5M Gates 672-FBGA | Intel

The Intel EP2A40F672I9 is a member of the APEX II family of field-programmable gate arrays (FPGAs), manufactured on a 0.15 µm CMOS process and packaged in a 672-pin FC-FBGA (flip-chip fine-pitch BGA). It integrates 1.5 million system gates and 38,400 logic cells, and is qualified for industrial-temperature operation (the "I" suffix). An FPGA (field-programmable gate array) is a type of programmable logic device that allows engineers to implement custom digital logic circuits after the silicon has been fabricated. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs), alongside CPLDs and SPLDs, and are widely used for glue logic, high-speed interfacing, DSP, and prototyping prior to ASIC tape-out. The APEX II family is an older generation of multi-gate FPGAs introduced in the early 2000s for high-density applications. Key features of the EP2A40F672I9 include 1.5 M system gates, 38,400 logic elements, embedded memory blocks, and support for multiple I/O standards. The device is supplied from a 1.5 V core rail and operates at a maximum internal clock frequency of 366 MHz. It supports in-system programmability via the IEEE 1149.1 JTAG interface, allowing configuration via Altera/Intel Quartus or legacy MAX+PLUS II software. The 672-ball FC-FBGA package is a high-pin-count surface-mount solution suited for high-speed signalling. The EP2A40F672I9 architecture combines look-up-table (LUT)-based logic, dedicated carry chains for arithmetic, embedded array blocks (EABs) for memory and DSP operations, and a high-speed interconnect fabric. Compared with earlier APEX devices, APEX II introduced higher density and improved routing, enabling single-chip solutions for telecom, networking, and digital-signal-processing systems. The 366 MHz internal performance rating reflects typical register-to-register paths and pipeline-friendly design style. Typical applications include high-density glue logic in telecom equipment, custom DSP and video/image processing pipelines, network packet processors, industrial control and instrumentation front-ends, and prototype ASICs that require rapid design iteration. The 672-ball BGA package provides enough I/O for multi-gigabit parallel buses and multiple memory interfaces. When designing with this device, ensure proper BGA layout with controlled-impedance traces and matched-length routing for high-speed signals. Power-decoupling, multi-rail sequencing (1.5 V core plus separate VCCIO banks), and thermal management (junction temperatures under the industrial grade range) are critical to reliability. Configuration memory planning and JTAG chain design must follow Intel/Altera application guidance.

In terms of architecture, the APEX II device integrates Logic Array Blocks (LABs) containing 10 LEs each, interconnected via the MultiCore interconnect, and offers up to 1.6 Mbits of embedded SRAM. The 0.15 micrometer CMOS process gives the device its 1.5 V core operation, while the I/O banks can be driven from 1.5 V up to 3.3 V depending on the chosen standard. Configuration is supported via passive serial, passive parallel, JTAG, and Altera's EPC configuration devices. Typical applications include ASIC prototyping, telecommunications line-card processing, high-speed image and video pipelines, test and measurement instrumentation, and PCI/PCI-X bus interface logic. Industrial and medical imaging systems frequently rely on the APEX II family because of the abundant dual-port memory and high I/O count. Military and aerospace customers adopt the I-temperature grade (suffix I9) for extended -40 C to +100 C operation. When designing with this device, ensure the Quartus II design toolchain (or legacy MAX+PLUS II) is available, plan the I/O bank voltages carefully, and respect the 1.5 V core supply decoupling guidance. The 672-ball FC-FBGA package requires X-ray inspection and controlled reflow profiles; thermal management is normally handled by the PCB copper pad array under the package.

The Intel (formerly Altera) EP2A40F780 is a member of the APEX II family of programmable logic devices, providing approximately 1,500,000 typical gates (30,000 logic elements) housed in a 780-pin FineLine BGA (FBGA) package. The APEX II architecture combines look-up table (LUT)-based logic with embedded system blocks (ESBs) for high-density combinational and sequential design implementation, targeting high-performance data path and datapath-intensive applications. A Field-Programmable Gate Array (FPGA) is a reconfigurable integrated circuit whose logic function is defined by a customer-supplied bitstream rather than fixed at the fab. FPGAs occupy the programmable-logic branch of the broader semiconductor hierarchy (FPGA -> programmable logic -> logic IC -> integrated circuit), and unlike ASICs they offer rapid time-to-market and in-system reprogrammability at the cost of higher unit price and static power consumption. The EP2A40 series is offered in multiple speed grades and package variants to address industrial, communications, and ASIC prototyping workloads. The 'F780' suffix denotes a 780-ball FineLine BGA package with an industrial operating temperature range, providing high I/O density for multi-channel datapath designs. Typical applications include ASIC prototyping, communications infrastructure, high-speed data-path implementations, custom DSP pipelines, and bus-interface bridging. The device supports SRAM-based configuration and JTAG (IEEE 1149.1) boundary-scan testing for production programming and in-field updates. Quartus II development tools are required for synthesis, place-and-route, and bitstream generation. When designing with this device, note that APEX II devices are legacy parts with active last-time-buy status at most franchised distributors; long lead times and price premium are typical. Engineers should validate tooling support in Quartus II version compatibility matrices before committing to new designs.

The device integrates approximately 40,000 typical gates, 540 user I/O pins, 655,360 bits of embedded RAM, and 38,400 logic elements, targeting high-performance data-path, telecommunication, and DSP front-end designs where both logic density and pin count are critical. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device that allows designers to configure digital logic blocks and interconnect via a hardware description language after manufacture. FPGAs occupy a hierarchical position from programmable logic device (PLD) -> complex programmable logic device (CPLD) -> FPGA -> programmable logic device family -> semiconductor. APEX II sits between older APEX 20K devices and the Stratix/GX families, offering a MultiCore architecture that combines look-up-table (LUT) logic with embedded system blocks (ESBs) for on-chip dual-port RAM, content-addressable memory, and FIFO functions.

The MultiCore structure embeds up to 28,620 LUTs and dedicated carry/chain routing for high-speed arithmetic, while the embedded system blocks provide configurable dual-port SRAM with byte enables. JTAG (IEEE 1149.1) boundary-scan test is supported for board-level verification. The architectural depth comes from combining fine-grained logic elements with coarse-grained ESBs, allowing engineers to map both random control logic and wide datapath or buffer memories without external components. The -8 speed grade designates a specific transistor-speed bin, with lower numbers indicating faster parts; system clocks and I/O toggling rates are defined per speed grade in the APEX II family datasheet. Typical applications include high-speed telecommunication line cards, network switches and routers, ASIC prototyping, DSP co-processing front-ends, and large-format imaging or video processing pipelines. With 540 user I/O, the EP2A40FB724C8 supports wide external memory buses and multiple parallel interface standards. Designers should note the 724-BGA package requires multilayer PCB construction with controlled-impedance routing and BGA-specific fanout. Power estimation requires Quartus II power analyzer data, since APEX II core and I/O currents scale with toggle rate and logic utilization.

The Intel EP2A70B652C8 is a high-density APEX II family FPGA integrating 67,200 logic elements (67200 LEs) and 1,125,000 system gates in a 652-ball BGA package with -8 speed grade, supplied as commercial-temperature (0C to +85C) tray packaging. It belongs to Intel's (formerly Altera's) APEX II architecture family, the first programmable logic platform to embed large on-chip SRAM and dedicated LVDS/DDR support on a single die. An FPGA (Field-Programmable Gate Array) is a programmable semiconductor that lets engineers implement arbitrary digital logic in hardware via post-fabrication SRAM configuration. Within the digital logic hierarchy it sits between CPLDs (lower density, non-volatile) and ASICs (higher density, fixed function, higher NRE); APEX II specifically targets on-chip bus architectures and multi-gigabit I/O bridges in mid-2000s telecom and computing platforms. Key features of the EP2A70B652C8 include 67200 logic elements, 1,125,000 typical gates, 4 Mbits of embedded SRAM distributed as True-LUT/LAB blocks, up to 4 PLLs with on-chip termination, and built-in LVDS interface capability. The BGA-652 footprint offers high pin-count density for parallel data paths and wide external memory buses. The APEX II multi-core architecture supports simultaneous high-speed I/O and embedded memory operations. The APEX II device uses a 0.15um CMOS SRAM process with embedded array blocks (EABs), look-up table (LUT) logic, and FastTrack continuous routing. This LUT + EAB hybrid architecture was designed for system-on-chip prototyping, allowing the designer to instantiate soft RISC cores, dedicated multipliers, and DDR memory controllers on the same fabric. Configuration is loaded via passive serial, parallel, or JTAG paths. Typical applications of the EP2A70B652C8 include telecommunications line-card interfaces, custom DSP accelerators, industrial control bridges, military/aerospace prototyping, and test & measurement backplanes. Its 4-Mbit embedded SRAM and 4 PLLs make it well-suited to designs that require buffering of high-speed data streams or multiple clock domains on a single device. Designers should treat this part as a mature, NRND-tier component: it is supported only through legacy design chains and the latest Intel Quartus II software releases, with long-term supply dependent on existing stocks.

EP2A70B652C9 - APEX II 70K LE FPGA, BGA-652 | Intel

The Intel EP2A70B652C9 is a member of the APEX II family of FPGAs (Field Programmable Gate Arrays), delivering approximately 70,000 logic elements (LEs) and 67,200 logic cells in a 652-ball BGA package. Built on a 0.18 micrometer CMOS process, this device targets high-density, high-performance programmable logic applications including ASIC prototyping, custom DSP, and high-speed interconnect bridging. An FPGA (Field Programmable Gate Array) is a type of integrated circuit containing an array of programmable logic blocks, configurable interconnects, and dedicated I/O cells that can be reconfigured after manufacturing to implement arbitrary digital logic. FPGAs sit in the programmable logic device (PLD) hierarchy, below CPLDs in density and above PALs/GALs. They are widely used for ASIC prototyping, low-volume custom logic, DSP acceleration, and parallel data-path applications where time-to-market and hardware flexibility outweigh the per-unit cost advantage of cell-based ASICs. APEX II was Intel's (formerly Altera) second-generation multi-gigabit, multi-volt family before being superseded by Stratix and subsequent families. Key features of the EP2A70B652C9 include dedicated on-chip memory blocks, embedded LVDS-capable I/O with multi-voltage support (1.5V, 1.8V, 2.5V, 3.3V), integrated PLLs for clock management, and up to 12 high-speed transceiver channels on speed-grade variants. The BGA-652 package supports up to 8 banks of user I/O, with routing density sufficient for memory-rich designs. Speed grade C9 places it in a moderate performance class within the APEX II lineup. Architecturally, APEX II uses a MultiCore architecture combining fine-grain logic elements (LEs) with MegaLAB blocks that include embedded array blocks (EABs) for efficient memory and multiplier implementation. The 7-level routing hierarchy provides a balance between performance predictability and routing flexibility. Multi-gigabit transceivers and True-LVDS support allow direct interfacing with high-speed backplanes and memory interfaces such as QDR and DDR SRAM. Typical applications include high-bandwidth telecommunications line cards, ASIC prototyping for SoC designs, custom DSP accelerators in medical imaging and radar signal processing, and high-speed serial protocol bridging. The combination of high logic density and on-chip memory makes it particularly suited for pipeline-parallel algorithms and protocol conversion functions. When designing with this part, consider the device's discontinued status in the Intel/Altera product catalog and use the open-source Quartus II design software for synthesis, place-and-route, and timing closure. Power estimation should use the PowerPlay tool within Quartus II before final board design.

EP2A70B724C7 - 3M-Gate APEX II FPGA | Intel | Embedded Logic

Altera EP2A70B724C7 is an APEX II field-programmable gate array with 3 million gates, 67,200 logic cells, and 540 I/O pins, supplied in a 724-pin FCBGA/BGA package. The verified results identify a 0.15 µm fabrication process, a 1.5 V supply, and operation up to 420 MHz. One result describes 1,146,880 bits of configuration or embedded memory, while another identifies 1,144,? bits; because the sources conflict, the precise memory value is not asserted here. The device belongs to the programmable-logic hierarchy: FPGA, programmable logic device, PLD, and semiconductor. It is designed for engineers implementing configurable digital systems, high-density glue logic, interfaces, and data-processing control circuits on a single integrated circuit. An FPGA is a programmable logic device whose configurable logic elements, routing, and I/O resources implement digital circuits after manufacturing. Unlike a fixed-function application-specific integrated circuit, the FPGA can be configured and reconfigured for different functions. The APEX II family targets high-density programmable logic, and EP2A70B724C7 combines a large logic-cell count with high I/O availability. Its package is identified in the verified data as 724-pin FCBGA, also described as 724-BBGA and PBGA724, with 35 mm by 35 mm body dimensions and 1.27 mm pitch in one source. The principal features are the 3M-gate APEX II architecture, 67,200 logic cells, 540 I/O, 1.5 V operation, and 420 MHz maximum frequency reported in the search data. The 0.15 µm all-layer copper-metal process is reported in the APEX II family result, which also references up to eight metal layers. True-LVDS, LVPECL, PCML, and HyperTransport interface capabilities are described in the family-level source. These characteristics make the device relevant to high-density, multi-interface equipment, although the verified text does not establish a single universal speed grade or all interface ratings for this exact ordering code. The reported 2.17 ns loadable-PLD figure and 420 MHz frequency should be interpreted as device-family or listing data rather than independently confirmed timing specifications for every configuration. A design must account for the selected device grade, process corner, voltage, temperature, routing, I/O standard, and implementation constraints. The part is therefore best treated as a high-density configurable platform whose practical throughput depends on the synthesized logic and the surrounding PCB environment. Typical uses include industrial control and automation, communications equipment, high-speed interface aggregation, test and measurement systems, and legacy digital-system replacement. The 540 I/O count supports systems with many parallel or serialized external connections, while the 67,200-cell capacity suits substantial datapath, protocol, and control integration. Buyers should confirm the exact package drawing, ball map, configuration interface, speed grade, and available inventory before release to production. The main design trade-off is density versus verification effort. A 724-ball BGA requires controlled fan-out, power distribution, decoupling, and signal-integrity review, while the large logic capacity can reduce the number of support devices in a system. This page provides a traceable starting point for EP2A70B724C7 sourcing and comparison, but the manufacturer datasheet and current distributor records remain the controlling documents for design approval.

The Altera (Intel Programmable Solutions Group) EP2A70B724C7ES is a high-density FPGA from the APEX II family, delivering 3 million system gates with 67,200 logic elements in a 724-pin FCBGA package operating at 420 MHz core performance on 0.15 µm process technology at 1.5 V core supply. The device combines programmable logic, embedded memory, and high-speed I/O in a single die, targeting high-throughput ASIC-replacement and glue-logic designs. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be re-programmed in-system after manufacturing. APEX II sits in the high-density tier of pre-Cyclone Altera families, between the APEX 20K and the Stratix line, and is characterized by its MultiCore architecture combining fine-grain logic with embedded ESB (Embedded System Block) memory blocks. Within the broader taxonomy, this places EP2A70B724C7ES in the programmable logic family, which sits above ASICs and CPLDs in flexibility/cost trade-off, and below modern SoC FPGAs in integrated features. Key features of the EP2A70B724C7ES include 3,000,000 typical gates (3M gates), 67,200 logic elements (cells), a maximum operating frequency of 420 MHz, on-chip ESB memory, support for multiple I/O standards including LVTTL, LVCMOS, PCI, and GTL+, and dedicated clock management with up to 8 PLLs per device. The 724-pin FCBGA package exposes 540 user I/O pins, enabling high-bandwidth parallel interfaces such as 64-bit PCI, DDR memory controllers, and multi-channel DSP pipelines. The architecture is based on Altera's MultiCore building block with a high-speed interconnect fabric and Look-Up Table (LUT) based logic cells. The 1.5 V core with 0.15 µm process technology reflects the APEX II generation's focus on balancing performance-per-watt with density, while the high I/O count supports wide external buses and multiple high-speed serial/parallel interfaces simultaneously. The C7 speed grade indicates a commercial temperature rating, with the 'ES' suffix denoting an engineering sample. Typical applications include high-speed telecommunications line cards, ASIC prototyping and replacement, ASIC emulation platforms, multi-channel DSP processing, video/image processing pipelines, and high-speed industrial data acquisition. The combination of high gate count and 420 MHz performance makes it suitable for designs previously requiring multiple FPGAs. When designing with this device, ensure your Quartus II design tool version supports the APEX II device family (Quartus II 5.0 or later is recommended) and verify BSDL files for boundary-scan programming. Note that APEX II is an older, mature family and may have limited long-term availability - confirm lifecycle status with authorized distributors before committing to new designs.

EP2A70B724C7N - APEX II FPGA, 67.2K LEs, 3M Gates, 724-FCBGA | Altera

The Altera (now Intel) EP2A70B724C7N is a high-density APEX II family FPGA delivering 3,000,000 system gates and 67,200 logic cells in a 724-pin FCBGA (Flip-Chip Ball Grid Array) package. Operating from a nominal 1.5V core supply at up to 420 MHz internal performance, it is built on a 0.15 µm CMOS process and is fabricated as a loadable programmable logic device with 536 user I/O pins and 16 mega cells of embedded memory. An FPGA (Field Programmable Gate Array) is a reprogrammable semiconductor device that contains an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells, all of which can be redefined by the designer after manufacture. FPGAs sit in the broader category of programmable logic devices (PLDs), which also include CPLDs and SPLDs. APEX II devices specifically target high-performance, high-density applications such as data-path acceleration, telecommunications backplanes, and ASIC prototyping, where the combination of embedded memory, PLLs, and high-speed I/O is critical. Key features include up to 420 MHz internal clock frequency, a propagation delay as low as 2.17 ns, 536 user I/O lines, and a 1.5 V core supply with multi-voltage I/O support. The device supports in-system programmability via JTAG and configuration via the Fast Passive Parallel (FPP) or Passive Serial (PS) modes. The 724-pin FCBGA package uses a 1.27 mm ball pitch and provides 3.5 mm seated height, making it suitable for high-density PCB designs with controlled impedance routing. Architecturally, the APEX II family combines Look-Up Table (LUT)-based logic elements with embedded system blocks (ESBs) that can be configured as dual-port RAM, ROM, or CAM. MultiVolt I/O pins allow interfacing with 1.5V, 1.8V, 2.5V, 3.3V, and 5V systems, which simplifies mixed-voltage designs. Built-in PLLs support clock multiplication, division, and phase shifting for high-speed serial or parallel interfaces. Typical applications include ASIC prototyping, telecommunications switching, high-speed data acquisition systems, DSP co-processing, and video/image processing pipelines. Industrial controls and military/aerospace systems also leverage the device for its high logic density and reconfigurability. Design considerations include careful power-rail sequencing on the 1.5V core, decoupling close to every supply pin, controlled-impedance routing for high-speed I/O, and JTAG chain management for board-level programming. Designers must also verify Quartus II device support and bitstream compatibility, as APEX II is supported by legacy Altera toolchains rather than the latest Intel Quartus Prime releases.

EP2A70B724C8 - APEX II FPGA 67200 LE 724-BGA | Altera

The Altera (now Intel) EP2A70B724C8 is an APEX II Field Programmable Gate Array (FPGA) featuring 67200 logic elements, 1146880 bits of embedded memory, and 540 user I/Os, housed in a 724-ball Fine-pitch Chip-Scale Ball Grid Array (FCBGA / BBGA) package. It is built on a 0.15 µm SRAM-based process and supports MultiVolt I/O operation, making it a high-density programmable logic platform for ASIC prototyping and complex parallel processing. An FPGA (Field Programmable Gate Array) is a type of integrated circuit containing an array of programmable logic blocks, programmable interconnects, and configurable I/O pads that the designer can reconfigure after manufacturing. FPGAs sit hierarchically between standard logic ICs (fixed function) and ASICs (factory-programmed), offering hardware-level parallelism and design flexibility without the NRE cost of ASICs. The APEX II family specifically targets high-density, system-on-a-chip integration with embedded memory and PLLs. Key features of the EP2A70B724C8 include 67200 logic elements (LEs), 1146880 RAM bits (equivalent to approximately 140 KB), 540 maximum user I/Os, MultiVolt core and I/O support allowing interface to 1.8V, 2.5V, 3.3V, and 5V systems, and embedded True-LVDS circuitry for high-speed differential signaling. The 724-BGA package uses a 1.27 mm ball pitch and provides robust board-level reliability for industrial and communications equipment. Technically, the APEX II architecture combines look-up-table (LUT)-based logic elements with embedded system blocks (ESBs) that can be configured as dual-port RAM, ROM, or first-in first-out (FIFO) buffers. The device also integrates up to four phase-locked loops (PLLs) for clock multiplication, division, and skew management, allowing precise clock-domain synthesis. Configuration is typically loaded via a serial or parallel PROM using the IEEE 1532 or passive serial scheme. Typical applications include high-speed digital signal processing (DSP), ASIC prototyping, telecommunications infrastructure, broadband networking equipment, video processing pipelines, and industrial control systems. Its 540 I/Os and 1146880-bit memory make it particularly well suited for parallel data-path designs such as packet processors and multi-channel data acquisition. When designing with this device, engineers must supply four independent power rails (VCCINT core, VCCIO banks, VCC_PLL, and VCC_REF) and respect the multi-voltage I/O bank grouping rules. Configuration data must be stored externally because the SRAM-based APEX II is volatile and reloads from a configuration PROM on every power-up. Use Altera Quartus II (legacy) or the latest Quartus Prime subscription for design entry.
