EP2A70B652C7 - 67200 LEs FPGA BGA-652 | Intel (Altera)
The Intel (formerly Altera) EP2A70B652C7 is a high-density Field-Programmable Gate Array (FPGA) from the APEX II family, integrating approximately 67200 logic elements (LEs) and 1140000 typical gates into a 652-ball FineLine BGA (BGA-652) package. It supports embedded system-on-chip (SoC) designs with on-chip memory blocks and supports multiple I/O standards including LVTTL, LVCMOS, SSTL, and LVDS through dedicated I/O banks. The device operates from a 1.8V core supply with separate VCCIO rails for I/O bank configuration. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit that contains an array of programmable logic blocks, configurable interconnects, and embedded resources such as memory blocks, DSP blocks, and high-speed transceivers. FPGAs sit in the programmable-logic segment of the digital IC hierarchy (FPGA -> programmable logic -> ASIC alternative -> digital integrated circuit -> semiconductor). Unlike fixed-function ASICs, FPGAs are post-fabrication reconfigured by the designer using HDL synthesis and place-and-route tools, accelerating prototyping and time-to-market for high-complexity designs. Key features of the EP2A70B652C7 include up to 336 user I/O pins distributed across multiple I/O banks, embedded SRAM blocks totaling several megabits, dedicated PLL clock management blocks for frequency synthesis and skew control, and support for high-speed LVDS signaling on selected pins. The APEX II architecture combines look-up-table (LUT) based logic with dedicated routing and memory resources to balance logic density, speed grade, and predictable timing closure in mid-to-large designs. The device uses a multi-voltage I/O structure with separate VCCIO banks, allowing mixed-voltage interfacing (1.5V, 1.8V, 2.5V, 3.3V) on the same die. It also supports in-system programmability via JTAG and passive serial configuration, enabling rapid board-level bring-up. The BGA-652 FineLine package provides a compact 27x27 mm footprint suitable for high-density PCB layouts in telecom, networking, and industrial control applications. Typical applications include high-throughput data-path processing in telecommunications line cards, glue-logic and protocol bridging in industrial controllers, image and video preprocessing for surveillance systems, and DSP co-processing in test and measurement instruments. The APEX II family was EOL'd by Altera/Intel and is now widely sourced through authorized distributors for legacy system support. When designing with this device, verify that your Quartus II design toolchain version supports the APEX II device family and that the chosen speed grade (C7 = commercial, 7th speed grade) meets timing closure requirements. Plan for thermal management because high utilization at elevated toggle rates can dissipate several watts; refer to the APEX II datasheet thermal management section for θJA values. Also confirm configuration memory and JTAG chain compatibility before board bring-up.

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. Plan verification cycles using Quartus II 9.1 or earlier service packs, as APEX II support was discontinued in later Quartus versions.

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 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.

The 3 M system-gate rating positions the EP2A70 well above mid-range FPGAs in capacity and below high-end Stratix-class devices. Typical applications include telecommunications line cards, ASIC prototyping, high-speed image processing pipelines, network switches/routers, and DSP co-processing. The 724-pin FCBGA package supports dense I/O layouts required by parallel bus architectures and high-pin-count memory interfaces. APEX II devices are commonly deployed in designs migrated from APEX 20KE families where higher logic density or extended I/O is needed. When designing with this part, ensure robust 1.5 V core power decoupling with low-ESR ceramic capacitors placed adjacent to every VCC/VCCIO pin pair. The FCBGA-724 package requires controlled-impedance PCB stack-up and microvia technology; reflow profile must respect the 724-ball mass and the moisture sensitivity level (MSL) preconditioning. Signal integrity at 198 MHz operation demands matched-length routing and proper termination on LVDS pairs.

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.

Key features of the EP2A70F1020C8 include dedicated hardware multipliers for DSP, on-chip True-LVT RAM blocks up to 1.125 Mbits total, MultiVolt I/O supporting 1.5V, 1.8V, 2.5V, and 3.3V interface levels, and Altera's SignalTap embedded logic analyzer interface. The 1020-FBGA FineLine BGA package provides a 33 mm × 33 mm footprint with 1.27 mm ball pitch, optimized for high-density board designs using standard BGA assembly processes. Architecturally, the APEX II device combines LUT-4 based logic elements with embedded system blocks (ESBs) that double as either dual-port RAM or FIFOs. The MultiVolt I/O ring lets the core run at 2.5V while driving 3.3V peripherals directly, simplifying mixed-voltage board designs. Internal phase-locked loops (PLLs) and a global clock network support designs with multiple synchronous clock domains at speeds up to 350 MHz on critical paths. Typical applications for the EP2A70F1020C8 include telecommunications line-card processing, high-speed serial protocol bridging, ASIC prototyping, custom DSP pipelines, and industrial control systems that need 100K+ LE of logic with abundant I/O. The 1020-ball BGA exposes enough I/O for parallel bus expansion, multiple LVDS channels, and external memory interfaces (DDR, QDR SRAM). When designing with this part, pay close attention to power sequencing (2.5V VCCINT before VCCIO), BGA PCB escape routing for the 1.27 mm pitch, and thermal management — at full utilization the part can dissipate 5W or more. Use the Altera Quartus II design suite (version 6.0 or later with APEX II device support) for synthesis, place-and-route, and timing closure.

The Intel (formerly Altera) EP2A70F1020C9 is a high-density APEX II family FPGA delivering approximately 70,000 typical gates of programmable logic in a 1020-ball FineLine BGA package. It exposes 735 user I/O pins for high-bandwidth system integration and supports a commercial operating temperature grade with a -9 speed grade designation. The device is part of Intel's mature APEX II programmable logic family that targets high-performance parallel processing and multi-gigabit interconnect. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that belongs to the broader semiconductor and integrated circuit hierarchy. FPGAs contain configurable logic blocks (CLBs), programmable interconnect, and dedicated I/O resources that engineers can reconfigure post-manufacturing to implement custom digital circuits, processors, or signal-processing pipelines. The APEX II family specifically targets high-density designs with embedded multipliers and memory blocks, making it suitable for DSP, communications, and parallel computing applications. Key features of the EP2A70F1020C9 include 1020-ball FBGA packaging, 735 user I/O pins for high pin-count designs, and APEX II architecture supporting embedded multipliers and high-speed interconnect. The device also offers JTAG-based configuration, support for multiple I/O standards, and ample on-chip memory resources typical of the 70K-gate density tier. The APEX II architecture integrates embedded array blocks (EABs), logic array blocks (LABs), and FastTrack interconnect to balance distributed logic with block memory and DSP operations. This makes the EP2A70F1020C9 suitable for designs requiring a mix of glue logic, datapath arithmetic, and FIFO or buffer memory. Typical applications include telecommunications infrastructure (SONET/SDH framer, packet processor backplanes), high-speed image and video processing pipelines, industrial test and measurement equipment, and military/aerospace digital signal processing subsystems. Designers also deploy APEX II devices in ASIC prototyping platforms where the 1020-ball BGA provides ample I/O for realistic I/O modeling. When designing with this device, ensure the PCB has a microvia-compatible stack-up for the 1.27 mm pitch FBGA and that thermal vias are placed under the package thermal pad. Power sequencing and decoupling follow APEX II family guidelines: separate VCCINT, VCCIO, and VCCPD rails with bulk and high-frequency ceramic decoupling placed close to each power pin cluster.
EP2A70F1508C6 - APEX II FPGA, 70K LE, 1508-BGA | Altera
The Altera EP2A70F1508C6 is a high-density member of the Altera APEX II programmable logic family, integrating approximately 70,000 logic elements (specifically 18,460 logic elements per the APEX II product family count) into a 1508-ball FineLine BGA package. It belongs to the APEX II device family, which combines look-up-table (LUT) based logic with embedded system blocks (ESBs) and a high-speed interconnect fabric for ASIC-replacement density at lower NRE cost. The 1508-BGA package provides 426 user I/O pins for high-bandwidth parallel interfaces in networking, DSP, and high-performance prototyping applications. A field-programmable gate array (FPGA) is a type of programmable logic device (PLD) that allows the designer to configure logic blocks, interconnect, and I/O behavior after PCB assembly. FPGAs sit hierarchically under programmable logic -> logic ICs -> integrated circuits -> semiconductors, and are commonly used to implement custom datapaths, glue logic, and parallel processing that would otherwise require an ASIC or a bank of discrete logic ICs. Key features of the EP2A70F1508C6 include 1,846 logic array blocks / configurable logic blocks (LABs/CLBs), 1,669,248 bits of total embedded SRAM distributed across ESBs, multi-standard I/O support, and in-system programmability via a JTAG interface or passive serial configuration. The APEX II family supports LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards, enabling direct interface to DDR memory and high-speed parallel ADCs/DACs without external level translation. Architecturally, the APEX II device combines a MegaLAB structure - groups of LABs sharing local interconnect - with a FastTrack Interconnect that provides predictable, compiler-driven routing across the die. This architecture makes the EP2A70F1508C6 suitable for high-fanout datapaths such as multi-channel DSP pipelines, protocol bridge ICs, and bus-conversion glue logic, where deterministic timing closure matters as much as raw gate count. Typical applications include telecommunications line cards, multi-channel baseband processing, high-speed serial protocol bridging, and ASIC prototyping. The 426 user I/O count makes the device attractive for memory-intensive designs where the designer must connect to multiple parallel DDR SDRAM banks or wide data-converter buses concurrently. When designing with the EP2A70F1508C6, pay attention to the package's thermal performance and the high pin density of the 1508-BGA - PCB stack-up, BGA fanout routing, and decoupling strategy all become critical. Use Altera's Quartus II design software (legacy version) for place-and-route and static timing analysis.
