EP2A70B724C9 - APEX II 540 I/O 724-BGA FPGA | Altera / Intel

The Intel / Altera EP2A70B724C9 is a member of the APEX II Field-Programmable Gate Array family, delivering 67,200 logic elements backed by 1,146,880 bits of embedded memory and 540 user I/Os in a 724-ball FineLine BGA package. Built on a 0.15-micrometer all-layer copper process with up to eight metal layers, it integrates up to eight LVDS channels operating at 1 Gbps and offers True-LVDS, LVPECL, PCML, and HyperTransport-compatible I/O standards. The 'C9' speed grade denotes the commercial temperature range (0C to +85C) and the 9th-order speed bin for this family. The 'B724' suffix confirms the 724-ball FineLine BGA footprint, while the package name on the part is listed as 724-BBGA, FCBGA. An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) that combines the flexibility of software-based design with near-ASIC performance and parallelism. APEX II sits in the hierarchy of programmable logic: PLD -> CPLD/FPGA family -> high-density SRAM-based FPGA -> multi-gigabit transceiver-capable device. APEX II was engineered for high-bandwidth DSP, datapath-intensive designs, and on-chip memory-rich applications requiring up to 1.146 Mbits of embedded system block (ESB) RAM and PLLs for clock management. Key features include embedded RAM blocks (ESBs) configurable as true dual-port, simple dual-port, or single-port synchronous memory, with self-timed write enable that eliminates external WE signal generation. The device supports up to four PLLs for clock multiplication, division, and phase shifting, and offers true 1 Gbps LVDS I/O for chip-to-chip interconnect. The 540 user I/Os include dedicated high-speed channels suitable for HyperTransport, RapidIO, and LVDS signalling, making APEX II well suited to high-throughput bridging and protocol conversion designs. The architecture combines Look-Up Table (LUT)-based logic with ESB memory, allowing designers to trade logic capacity against memory capacity per design block. Multi-level interconnect with fast row and column paths targets DSP and datapath workloads where sustained arithmetic throughput matters more than raw clock rate. FineLine BGA packaging supports dense board layouts while preserving signal integrity for the high-speed LVDS channels, which require matched impedance routing and careful length matching. Typical applications include high-speed serial protocol bridging (RapidIO, HyperTransport, custom LVDS links), DSP co-processing for wireless baseband or video pipelines, datapath acceleration in telecom line cards, and high-density glue logic with embedded memory buffering. The wide I/O count also suits it for memory-controller fanout and large bus-conversion designs where many parallel interfaces must be aggregated. When designing with this device, ensure proper LVDS signal integrity with controlled-impedance routing and matched-length traces; verify JTAG chain integrity in production programming; and follow Altera's power estimation flow using the Quartus APEX II power calculator before sign-off. Synchronous RAM blocks require careful clock-domain crossing analysis when shared with asynchronous logic. This page synthesizes distributor pricing for EP2A70B724C9, same-family drop-in alternatives within the APEX II lineup, and practical design notes beyond what the manufacturer datasheet alone provides.

From a system-architecture perspective, FPGAs occupy a distinct tier in programmable logic: they sit above standard Complex Programmable Logic Devices (CPLDs) in capacity and below Application-Specific Integrated Circuits (ASICs) in per-unit cost, while offering parallel hardware fabrics that can be reconfigured after PCB assembly. The APEX II family targets high-density data-path applications such as telecommunications backplanes, parallel DSP, and high-speed bus bridging, where a designer needs ASIC-class throughput without NRE tooling costs. Typical applications for the EP2A70B724I-8 include communications infrastructure (SONET/SDH framer ICs, ATM switching fabrics, 10/40 Gb Ethernet packet processors), high-performance DSP (FIR filters, FFT engines, baseband modem processing), and ASIC prototyping/emulation platforms. The 724-pin FCBGA package exposes roughly 380 user I/O pins, sufficient for wide parallel buses such as 64-bit SDRAM interfaces or multi-channel LVDS links. When designing with this part, pay particular attention to multi-rail decoupling: the 1.5 V core, 3.3 V I/O bank supplies, and PLL analog supply must each be filtered with low-impedance ceramic capacitors placed within 5 mm of their respective pins. Configuration via JTAG or passive serial should be planned against the board's boot-time budget because the configuration image for a 70K-cell device typically exceeds 1 Mbit. This page synthesizes distributor availability, same-family APEX II alternatives, and practical PCB design notes not found in a single Altera datasheet chapter. Engineers evaluating EP2A70B724I-8 for legacy or long-lifecycle programs should review the lifecycle status carefully before committing to new board designs.

EP2A70B724I-9

EP2A70B724I-9 - APEX II FPGA 70K LE, BGA-724, -9 Speed | Altera / Intel

The Altera (Intel) EP2A70B724I-9 is a member of the APEX II family of Field-Programmable Gate Arrays (FPGAs) that delivers up to 70,000 typical logic elements and 4,290 Kbits of embedded RAM in a 724-pin BGA package with -9 speed grade and industrial temperature rating. As part of the APEX II series, it integrates LUT-based logic, embedded memory blocks, and a MultiCore interconnect that supports high-performance data-pipeline designs. The -9 speed grade designates one of the faster bin positions in the APEX II family, providing higher Fmax than -10 (slower) grades at typical process corners. APEX II (Advanced Programmable Element Matrix II) is Altera's second-generation MultiCore architecture FPGAs that combine look-up-table (LUT) logic, embedded system blocks (ESBs) for memory, and a hierarchical row/column interconnect for predictable timing closure. They are positioned in Altera's product hierarchy as APEX II -> APEX family -> SRAM-based programmable logic -> FPGA -> programmable logic device -> semiconductor. APEX II devices were widely adopted in high-density glue logic, data-path processing, and pre-SOC prototyping designs of the late 1990s and early 2000s. Key features include high-density fine-grained logic with 70K typical LEs, 4,290 Kbits of embedded system block (ESB) memory for distributed RAM and FIFO applications, and the MultiCore interconnect that provides predictable row-and-column based routing. The -9 speed grade targets higher clock-frequency designs versus the slower -10 bin. The 'I' suffix designates the industrial temperature range (-40C to +100C operating), making it suitable for harsh-environment deployments. The BGA-724 package with 1.27 mm pitch is the largest in the APEX II family and supports maximum user I/O for dense interconnect. Typical applications include high-performance data-path processing, telecom protocol engines, network switch fabric, and legacy high-density glue-logic replacement. The large embedded memory count makes it suitable for FIFO-intensive designs such as ATM/SDH framers and base-station channel cards. APEX II devices retain an installed base in industrial control and military/aerospace systems where long lifecycle support and ITAR/legacy compatibility matter more than raw modern Fmax. When designing with the EP2A70B724I-9, engineers must use the legacy Altera Quartus II design tool (versions 4.x-9.x recommended) since later Quartus versions dropped APEX II device support after Altera's 2010+ portfolio refresh. Configuration requires an EPC4, EPC8, or EPC16 enhanced configuration device or a passive serial/PROM-based boot. Decoupling guidelines call for at least 12 bulk + 24 high-frequency capacitors distributed around the BGA power pins to control simultaneous switching noise.

EP2A70B724I8 - APEX II 70K LE FPGA 724-FCBGA | Altera

The Intel (formerly Altera) EP2A70B724I8 is a member of the APEX II family of programmable logic devices, providing up to 67200 logic elements (LEs), 3 million system gates, and a 0.15 µm CMOS process with a 1.5 V core supply. It is packaged in a 724-pin FineLine BGA (FCBGA) and operates across the industrial temperature range (-40 °C to +100 °C), as indicated by the trailing "I" suffix. The "8" speed grade corresponds to an internal performance index targeting roughly 281 MHz in typical data-path designs. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit built around a matrix of configurable logic blocks (CLBs), embedded memory blocks, and programmable interconnect that can be reconfigured by the customer after manufacture. APEX II devices sit in the high-density, multi-standard I/O tier of the Altera product tree: FPGA -> programmable logic -> programmable logic IC -> semiconductor. Each LE is paired with a four-input lookup table, a programmable register, and dedicated carry chain logic, while embedded system blocks (ESBs) implement dual-port RAM, ROM, and CAM. The combination makes APEX II suitable for bus interfaces, on-chip datapaths, and glue-logic consolidation. Key features of the EP2A70B724I8 include 67200 LEs, 3 M system gates, embedded multiplier support, True-LVDS and high-speed I/O standards, and a dedicated phase-locked loop (PLL) block for clock multiplication and deskew. The device supports active serial, passive serial, and passive parallel asynchronous configuration modes through the EPC4/EPC8/EPC16 enhanced configuration devices, and in-system programmability via JTAG (IEEE 1149.1). Each I/O bank is independently powered, allowing mixed-voltage interfacing (1.5 V, 1.8 V, 2.5 V, 3.3 V) on the same die. The architecture is built on a 0.15 µm metal-layer CMOS process with eight layers of interconnect for low-skew global clock distribution. The embedded system block memory ranges to hundreds of kilobits and can be concatenated horizontally or vertically. TriMatrix memory supports per-bit write-masking and mixed-width data ports. The PLL block generates up to four derivative clocks with sub-100 ps jitter, while the MultiTrack interconnect minimizes routing congestion in dense designs. Typical applications include telecommunications line cards, high-speed serial protocol bridging (UTOPIA, SPI-4.2, POS-PHY), DSP co-processing front-ends, and industrial control backplanes. The wide LVDS I/O count makes it well suited to bus multiplexing and parallel-to-serial concentration tasks. When designing with this part, plan for a 1.5 V core supply, four PLL analog supplies (VCC_PLL pins), and careful bank voltage grouping; the 724-pin FCBGA requires a multilayer PCB with microvia fan-out. Use the Quartus II design software (legacy support) for synthesis, place-and-route, and timing closure; signal-integrity simulations should account for simultaneous switching noise on the 1.5 V rail.

FPGAs sit above general-purpose microcontrollers and below fixed-function ASICs in the programmable-logic taxonomy (FPGA -> programmable logic -> semiconductor IC), offering parallel processing, deterministic timing, and hardware-level customization for data-path acceleration, glue logic, and prototyping. The APEX II family specifically targets high-density, multi-standard I/O designs by integrating up to four embedded system blocks (ESBs) with each ESB providing up to 32 Kbits of dual-port RAM. Key features of the EP2A70B724I9 include 540 Kbits of embedded memory, 4 phase-locked loops (PLLs) for flexible clock management, support for multiple I/O standards including LVTTL, LVCMOS, SSTL, and HSTL, and an industrial operating temperature range. The 724-pin FCBGA package provides a high-density interconnect suitable for high-speed designs with numerous differential pairs and high pin-count I/O requirements. The EP2A70B724I9 architecture combines four-input look-up tables (LUTs) with embedded system blocks and high-speed interconnect, allowing designers to implement both register-rich datapaths and memory-intensive functions in a single device. The PLLs allow multiple clock-domain synthesis and zero-delay buffering for backplane or source-synchronous interfaces such as LVDS and SSTL. Typical applications include telecommunications infrastructure, network switching and routing equipment, high-speed serial backplanes, digital signal processing (DSP) pipelines, and ASIC prototyping. The high logic density and embedded memory make the EP2A70B724I9 well suited for datapath-heavy designs such as protocol bridges, packet processors, and image-processing front-ends. When designing with this device, careful attention must be paid to power integrity: the 1.5 V core and PLL supply must be decoupled with low-ESR ceramics placed close to the FCBGA balls, and the high pin count drives a complex multi-layer PCB stack-up. Signal-integrity simulations are recommended for LVDS and high-speed DDR interfaces.

EP2A70B724I9N - APEX II FPGA 3M Gates 724-FCBGA | Intel

The Intel EP2A70B724I9N is a high-density FPGA from the APEX II family, delivering 3 million system gates, 67,200 logic cells, and a maximum internal clock frequency of 198 MHz. The device is built on a 0.15 µm CMOS process and operates from a 1.5 V core supply, packaged in a 724-ball Flip-Chip BGA (FCBGA). It is the highest-density member of the EP2A70 series, targeting data-path-heavy designs that need abundant embedded memory and high I/O bandwidth. What is an FPGA? An FPGA (Field-Programmable Gate Array) is a programmable logic device in the broader semiconductor taxonomy: programmable logic -> logic IC -> integrated circuit. FPGAs are used for digital logic prototyping, parallel processing, glue logic, and ASIC replacement. The APEX II family specifically extends the Altera APEX architecture with embedded system blocks (ESBs) and a MultiCore interconnect that supports both fine-grained logic and coarse-grained memory, making it suitable for designs that blend control logic with datapath processing. Key features of the EP2A70B724I9N include 536 maximum user I/O pins, multiple embedded system blocks for RAM/ROM/CAM, support for high-speed LVDS I/O, and a true dual-port RAM architecture. The device supports in-system programmability through IEEE 1532 and supports configuration via passive serial, passive parallel, and JTAG modes. The 724-ball FCBGA package offers high pin density, enabling dense board layouts for telecom, networking, and DSP applications. The EP2A70B724I9N architecture combines a MultiCore interconnect with embedded system blocks to deliver predictable performance for memory-intensive and I/O-intensive designs. Designers can instantiate on-chip RAM, ROM, and CAM blocks without using logic cells, freeing fabric for parallel datapath operations. The 1.5 V VCCINT and 3.3 V-tolerant I/O architecture is typical for the APEX II generation, and the 724-FCBGA package supports high signal-count designs that would not fit in smaller BGA or QFP packages. Typical applications for this part include telecom line cards, ATM switching fabrics, high-speed serial protocol bridging, DSP front-end preprocessing, network router aggregation, and ASIC prototyping. The combination of 67,200 logic elements and 3M system gates supports designs that previously required an ASIC. When designing with the EP2A70B724I9N, pay attention to power integrity and thermal management. The 1.5 V core rail must be tightly regulated; a switching DC-DC followed by an LDO post-regulator is the typical pattern. Decoupling and PCB stackup planning for the 724-FCBGA is essential because the BGA escape routing demands microvia stackups. Always verify the specific ball map against the published pinout before layout. This page synthesizes distributor pricing, same-family Intel/Altera alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers evaluate the EP2A70B724I9N against extendable APEX II family members.

The device features 735 user I/O pins, enabling dense connectivity in data-path and backplane designs. An FPGA (Field-Programmable Gate Array) is a reprogrammable semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnects, and dedicated I/O cells that an engineer can configure to implement arbitrary digital hardware. Within the broader taxonomy, FPGAs belong to programmable logic devices (PLDs), which sit alongside ASICs (application-specific integrated circuits) and microcontrollers in the digital IC ecosystem. The APEX II family was Altera's high-density offering for multi-gigabit signal processing and high-end parallel computing, preceding the Stratix and Cyclone architectures. Key parametric features of the EP2A70F1020 include 67200 logic elements/cells as reported in distributor parametric summaries, 735 user I/O pins distributed across multiple banks, embedded system blocks (ESBs) for memory and arithmetic, and support for multiple I/O standards including LVDS, SSTL, and GTL+. The APEX II architecture combines LUT-based logic with dedicated carry chains, embedded RAM, and high-speed interconnect to deliver deterministic timing closure for pipelines operating at hundreds of MHz. Technically, the APEX II device uses a 1.5V core voltage with separate VCCIO rails for I/O bank flexibility. The 1020-ball FBGA package supports high signal integrity at multi-hundred-MHz operation through controlled-impedance ball assignment and short bond-wire interconnects. Programming is performed via JTAG or passive serial configuration, with bitstream compatibility across the APEX II family enabling design migration between density points. Typical applications of the EP2A70F1020 include telecom protocol processing, high-speed image and video processing pipelines, ASIC prototyping, custom compute accelerators for DSP workloads, and backplane bridge logic in networking line cards. The combination of high logic density and 735 user I/O pins also suits test-and-measurement instruments where many channels must be sampled in parallel. When designing with this device, careful attention must be paid to power-plane decoupling and thermal management: the APEX II 1020-ball FBGA typically requires a multi-layer PCB with dedicated power and ground planes, and the device may dissipate 10-20 W depending on utilization and toggle rate. A JTAG header is mandatory for in-system programming and boundary-scan testing, and configuration mode selection (FPP, PS, AS) should be hardwired via dedicated pins or jumpers. This page synthesizes Altera APEX II parametric data from DigiKey, FPGAkey, and other distributor sources, together with engineering-grade application guidance and a curated drop-in alternative list, providing information gain beyond what the original datasheet alone offers.

EP2A70F1020C7 - 70k LEs FPGA, 735 I/O, 1020-FBGA | Intel (Altera)

The Intel (formerly Altera) EP2A70F1020C7 is a high-density Arria-family FPGA from Intel's legacy APEX II programmable logic family, integrating approximately 67,200 logic elements and a 1020-ball FineLine BGA package with 735 user I/O. The 'C7' speed grade and 'F' package suffix identify a commercial-temperature 0.7 ns speed bin in the flip-chip BGA package family. A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), embedded memory blocks, DSP blocks, and programmable interconnect that can be reconfigured by the end user after manufacturing. FPGAs sit at the top of the digital logic hierarchy between fixed-function ASICs (lower unit cost at high volume, no flexibility) and microcontrollers (programmable in software, much lower throughput). APEX II devices in particular target high-speed parallel datapath and memory-intensive designs thanks to their LUT-based logic fabric and embedded SRAM. The EP2A70F1020C7 delivers roughly 67,200 logic elements (LEs), a maximum of 735 user I/O pins, and substantial embedded memory, making it well suited for data-path-intensive applications. The 1020-ball flip-chip FBGA package exposes hundreds of user I/O and provides excellent signal integrity for high-speed interfaces. Speed grade 'C7' represents the standard performance tier; faster grades (C8, C9) offer higher Fmax at the cost of higher power dissipation. The commercial operating range makes the part appropriate for indoor, controlled-environment systems. Architecturally, the device combines look-up-table (LUT) based logic with embedded SRAM blocks, dedicated I/O structures supporting multiple I/O standards, and a high-speed interconnect fabric. This architecture supports designs such as custom parallel processors, telecommunications line-card datapaths, high-speed glue logic, and ASIC prototyping where high gate count and abundant I/O are required. Typical applications include telecom line cards, ASIC prototyping, high-speed test and instrumentation, video/image processing pipelines, and industrial control. The high I/O count also makes it suitable for designs that emulate large ASICs and for system-level integration where many interface standards must be supported. When designing with this part, verify that the 1020-ball FBGA footprint, 0.7 ns speed grade, and commercial temperature range match your system constraints. Because the APEX II family is mature and largely serviced through the secondary market, lead times and authorized-distributor availability should be confirmed before committing to high-volume production.

Altera EP2A70F1508C7N is a high-density APEX II Field Programmable Gate Array built in 0.15 µm CMOS technology, with 67,200 logic cells, 1,060 programmable I/O pins, and a stated 420 MHz capability. The device is offered in a 1508-pin FC-FBGA package and operates across 0°C to 85°C. Its architecture belongs to the programmable-logic hierarchy between an FPGA and a configurable digital system-on-chip, giving engineers a platform for parallel datapaths, interface bridging, and high-I/O digital control. An FPGA is a semiconductor containing configurable logic blocks, routing resources, and programmable I/O elements. Unlike a fixed ASIC, an FPGA can be configured after manufacturing and revised in the field. It sits within the broader semiconductor hierarchy as programmable logic, sharing the same general class as CPLDs while providing much higher logic density, embedded memory, and parallel processing capability. APEX II devices combine logic, memory, and interface resources in one programmable fabric. The headline density of 67,200 cells supports large combinational and sequential designs, while 1,060 programmable I/O pins provide substantial external connectivity. The APEX II family is identified in the verified data as providing 6,720 logic array blocks and 1,146,880 total RAM bits. The device also carries a 3 million-gate family description in the supplied sources. A 1.5 V core and 0.15 µm CMOS process place the component in a mature high-density FPGA family rather than a modern low-power architecture. The listed 420 MHz figure describes the device's stated capability, but system-level performance depends on placement, routing, configuration, clock resources, I/O standards, and design implementation. The combination of high cell count and high I/O count is useful for designs that require many independent interfaces or wide parallel buses. Designers should use the manufacturer timing documentation and supported software flow for the exact device variant before committing to a clock target. Typical applications include telecommunications equipment, industrial automation, test and measurement, video or image processing, and communications infrastructure. The large RAM resource suits buffering and packet or sample processing, while the 1,060 I/O pins can support broad sensor, memory, or peripheral interfaces. The 0°C to 85°C temperature range is appropriate for many commercial and industrial environments, but system airflow and junction conditions still require review. When designing with EP2A70F1508C7N, verify the complete 1508-pin FC-FBGA land pattern, power sequencing, configuration interface, and supported configuration memory. The verified data does not provide the full pin assignment, package dimensions, supply-current limits, or thermal resistance, so those values remain [DATA_NEEDED] rather than inferred.

The 1060-pin user I/O count, combined with 1,146,880 RAM bits, makes it one of the largest devices in the APEX II lineup and the highest-density member of the EP2A70 speed/packaging family. The EP2A70F1508C8 fabric uses an embedded array architecture with logic array blocks (LABs) and embedded system blocks (ESBs) that include dual-port RAM and ROM. The 0.15 µm eight-layer copper process delivers high integration density while keeping die area manageable for the 1508-ball FCBGA. Typical applications include high-throughput telecommunications line cards, video broadcasting equipment, industrial imaging pipelines, and custom ASIC prototyping. The 1060 I/O count is particularly useful for designs that require wide parallel buses (PCI, DDR, video) or many independent control signals. When designing with this device, plan power sequencing for the 1.5 V core and 3.3 V I/O rails, and follow Altera's recommended decoupling and ball-pitch layout rules for the 40x40 mm FCBGA package. Engineers should also evaluate newer Cyclone or Arria families for new designs since APEX II is mature and replacement silicon is recommended for greenfield projects.

It operates on a 1.5 V core supply, supports in-system programmability via SRAM configuration memory, and is offered in the commercial -8 speed grade. An FPGA (Field Programmable Gate Array) is a type of programmable logic device that allows designers to implement custom digital circuits through configuration of internal logic blocks, embedded memory, and routing resources. APEX II sits in the hierarchy: FPGA -> programmable logic -> logic IC -> integrated circuit -> semiconductor, and is widely used as a flexible ASIC replacement in high-performance digital designs where time-to-market and design flexibility outweigh pure unit-cost optimization. Key differentiating features include 1,146,880 system gates, 67,200 logic elements, embedded system blocks (ESBs) implementing dual-port RAM, ROM, FIFO and CAM, and 1,060 maximum user I/O. The -8 speed grade corresponds to approximately 100 MHz internal operation in APEX II silicon. The device supports multiple I/O standards including LVTTL, LVCMOS, PCI, SSTL, and LVDS through dedicated I/O banks. The APEX II architecture combines a MultiCore interconnect fabric with embedded system blocks for memory-intensive functions. Each ESB provides up to 2,048 bits of dual-port RAM, and the embedded multipliers plus PLLs support DSP-style signal processing and clock management. The 1508-FCBGA package exposes the largest I/O count in the family, enabling high-bandwidth parallel interfaces. Typical applications include high-speed communication ASIC prototyping, telecom line-card glue logic, industrial vision and image-processing pipelines, ASIC emulation, and high-performance data-path acceleration. The large gate count supports entire subsystems (RISC soft-cores plus peripherals) on a single device. When designing with this part, plan power integrity carefully: a fully populated EP2A70 can exceed 2-3 A core current with transients during configuration. Use a multi-layer PCB with dedicated power planes and bulk ceramic decoupling at the FCBGA's underside balls.

Built on a 0.15-micron all-layer copper-metal process with up to eight metal layers, this device targets high-performance, high-bandwidth system designs requiring 1-Gbps True-LVDS, LVPECL, PCML, and HyperTransport interface support. The commercial speed grade is C8 with a maximum internal frequency of 281 MHz. An FPGA (Field Programmable Gate Array) is a type of Programmable Logic Device (PLD) that combines the programmable interconnect fabric of a PLD with the register-rich architecture of a gate array. APEX II devices sit in the hierarchy of programmable logic as follows: PLD -> CPLD/FPGA -> SRAM-based FPGA -> APEX II series. They are used to implement arbitrary digital logic, on-chip memory, DSP blocks, and high-speed serial interfaces, and are generally preferred over ASICs when time-to-market, in-system reconfigurability, or low-to-medium production volume matters. Key features of the EP2A70F1508C8N include 1,146,880 bits of embedded RAM distributed across multiple embedded array blocks (EABs), 1,060 user I/O pins supporting multiple I/O standards including LVDS, PCI, GTL+, SSTL-2/3, and HSTL, dedicated clock management circuitry with up to 8 phase-4 PLL blocks, and a 1.5V core supply. The 1508-ball FC-FBGA package uses a 1.00 mm ball pitch with a seated height of 3.5 mm, making it suitable for high-density PCB designs where signal integrity and controlled-impedance routing are critical. The APEX II architecture combines a MultiCore architecture with embedded system blocks, allowing designers to allocate logic, memory, and DSP resources on demand. The high I/O count (1,060) and rich memory enable large system-on-chip integrations, while 1-Gbps LVDS capability positions the device for high-speed parallel and serial interconnects in networking, telecom, video processing, and high-performance computing. Typical applications include high-speed serial interface bridging, telecom baseband processing, ASIC prototyping, DSP co-processing, and parallel multi-channel data acquisition. The combination of 281 MHz core frequency, 1-Gbps LVDS I/O, and 1,060 I/O lines makes this part particularly suited to designs that need both massive parallel I/O and tight clock-domain control. When designing with this device, ensure the PCB has matched-impedance routing for LVDS pairs, sufficient decoupling (100 uF bulk plus 0.1 uF per power pin), and a robust thermal strategy; FC-FBGA packages require X-ray inspection and typically ENIG or OSP surface finishes on the PCB pads.

EP2A70F1508C9 - APEX II FPGA 67.2K LE 1.5V 1508-FBGA | Intel / Altera
EP2A70F1508C9

EP2A70F1508C9 - APEX II FPGA 67.2K LE 1.5V 1508-FBGA | Intel / Altera

The Intel (formerly Altera) EP2A70F1508C9 is a member of the APEX II family of Field Programmable Gate Arrays, built on a 0.15 µm all-layer copper-metal process with up to eight metal layers and offering 67,200 logic elements (LEs) plus 1,146,880 bits of embedded RAM. The device is housed in a 1508-ball FCBGA (Fine-pitch Chip-Scale Ball Grid Array) package measuring 40 × 40 mm, supports a 1.5 V core supply, and is rated for the commercial 0 °C to 85 °C operating range. It is one of the largest, most I/O-rich members of the APEX II generation, originally designed for high-density, high-bandwidth parallel datapath and multi-gigabit serial-interface designs. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit that lets engineers implement arbitrary digital logic, including complex state machines, datapaths, and signal-processing pipelines, after the device has been manufactured. Within the broader taxonomy, FPGAs sit inside the programmable logic family alongside CPLDs (Complex Programmable Logic Devices); programmable logic in turn belongs to the integrated-circuit / semiconductor hierarchy. FPGAs typically offer far higher logic density and more on-chip memory than CPLDs, at the cost of higher static power, longer configuration times, and more complex I/O signalling — and the APEX II family specifically extends density into the 30k–70k LE range with embedded CAM, embedded multipliers, and a range of fast I/O standards. Key features of the EP2A70F1508C9 include 1,060 user I/O pins (per the 1508-BBGA FCBGA package), 4 PLLs, support for 1-Gbps True-LVDS, LVPECL, PCML, and HyperTransport™ interface signalling, dedicated carry and cascade chains for arithmetic-heavy designs, and on-chip memory that can be configured as RAM, ROM, or FIFO. Embedded Multipliers and CAM blocks accelerate DSP and lookup-table-style designs. Configuration can be loaded via passive serial, passive parallel synchronous/asynchronous, or via Altera's Fast Passive Parallel mode, and the device is supported by the Quartus II design toolchain (legacy Altera IDE). Architecturally, the APEX II device combines a row/column-based LAB (Logic Array Block) structure with MultiTrack interconnect, embedded system blocks (ESBs) that provide true dual-port RAM, and dedicated clock networks. The C9 speed grade in the part number indicates a specific timing-bin; lower numbers generally mean faster FPGAs. Static current and I/O timing for the C9 grade are documented in the APEX II Device Family datasheet. Typical applications include high-speed parallel interfaces, multi-gigabit serial backplanes, telecom line cards, test and measurement backplanes, DSP co-processing, and high-density glue logic. Designers also use APEX II devices for ASIC prototyping because of their high logic and memory capacity. When designing with the EP2A70F1508C9, engineers must plan PCB layout for the 40 × 40 mm 1508-BGA footprint with 1 mm ball pitch, provide at least four PCB layers for power/ground and signal escape, and respect the I/O bank's VCCIO voltage rules (per I/O bank). Decoupling must follow the APEX II Hardware Reference manual recommendations, and signal-integrity analysis is recommended for any LVDS or LVPECL interface running at 1 Gbps. Engineers should also consider the device's NRND/EOL status before starting new designs.

EP2A70F1508C9ES - 3M Gates APEX II FPGA 1508-FCBGA | Altera

The Altera EP2A70F1508C9ES is a member of the APEX II family of Field Programmable Gate Array (FPGA) devices, delivering 3 million system gates, 67,200 logic elements, 1,146,880 bits of embedded RAM, and 1,060 user I/O pins in a 1508-ball flip-chip FineLine BGA (FC-FBGA) package. It is fabricated on a 0.15 µm CMOS process and operates from a 1.5 V core supply (1.425 V to 1.575 V). The device supports internal clock rates up to 198 MHz and offers propagation delays suitable for high-performance programmable logic designs. An FPGA (Field-Programmable Gate Array) is a type of integrated circuit that can be configured by the customer after manufacturing to perform a wide range of digital logic functions, sitting in the semiconductor hierarchy between ASICs and CPLDs. FPGAs combine programmable logic elements, interconnect, and dedicated memory blocks, making them a sub-category of programmable logic devices (PLDs) within the broader integrated circuit family. Key features include MultiCore architecture integrating logic, memory, and DSP building blocks, four Phase-Locked Loops (PLLs) for clock management, support for multiple I/O standards including LVDS, LVTTL, LVCMOS, SSTL, HSTL, PCI, and GTL, and True-LVDS support for high-speed differential signaling. The device also supports up to 24 megabytes of external memory via dedicated interfaces. The APEX II architecture combines a fine-grained embedded structure with Look-Up Tables (LUTs), product-term logic, and embedded system blocks (ESBs) that can implement dual-port RAM, ROM, FIFO, and CAM functions. This hybrid architecture allows efficient mapping of both datapath and control logic on the same die. Embedded multipliers accelerate DSP operations, while the four PLLs provide flexible clock synthesis and skew management. Typical applications include telecommunications infrastructure, high-speed data switching, ASIC prototyping, parallel DSP processing, and embedded computing platforms where high I/O count and substantial logic density are required. The wide I/O count of 1,060 makes it suitable for parallel data-path and protocol-bridging designs. When designing with this device, careful attention must be paid to power distribution network design because the 1.5 V core and multiple I/O banks each require separate decoupling. The flip-chip BGA package demands controlled-impedance PCB layout with matched-length traces for LVDS and clock signals.
