EP2C70F672C7 - Cyclone II FPGA 68K LE 672-BGA | Intel

The Intel (formerly Altera) EP2C70F672C7 is a member of the Cyclone II family of low-cost Field-Programmable Gate Arrays (FPGAs), delivering 68,416 logic elements, 4,276 Configurable Logic Blocks (CLBs), and 1,152,000 bits of embedded RAM in a 672-ball FineLine BGA package. Built on a 90 nm CMOS process, the device operates from a 1.2 V core supply and supports 422 user I/O pins across 8 I/O banks, with per-pin support for multiple I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and HSTL. An FPGA (Field-Programmable Gate Array) is a class of programmable logic device that allows designers to implement custom digital circuits using a matrix of configurable logic blocks (CLBs), embedded memory blocks, multipliers, and programmable interconnect. FPGAs sit between general-purpose microcontrollers and fixed-function ASICs in the design hierarchy: more flexible than an ASIC, but faster and more deterministic than a software-driven processor. The Cyclone II family specifically targets cost-sensitive, high-volume applications where designers need ASIC-like integration without the NRE mask charges. Key features of the EP2C70F672C7 include 150 embedded 18x18 multipliers (approximately 300 9x9 multipliers), four PLLs for clock management, and support for external memory interfaces such as DDR, DDR2, SDRAM, and QDRII SRAM. The device delivers up to 500 MHz internal performance per the manufacturer datasheet and supports configuration via passive serial (PS), active serial (AS), and JTAG modes, with built-in decompression and encryption for bitstream security. Architecturally, the Cyclone II device uses a lookup-table (LUT)-based logic fabric with embedded M4K memory blocks (each 4 Kbits, configurable as RAM, ROM, or shift register) and dedicated multiplier blocks for DSP functions. The 90 nm process balances cost, density, and static power, making it well suited for video processing, industrial control, and communications infrastructure designs. Typical applications include digital video surveillance, industrial machine vision, motor control, software-defined radio front-ends, protocol bridging in telecom equipment, and ASIC prototyping. The high logic density and embedded multipliers also make it suitable for image processing pipelines and low-to-mid complexity DSP workloads. When designing with this part, pay close attention to power sequencing: the 1.2 V VCCINT, 2.5 V VCCAUX, and I/O VCCIO rails must come up in a defined order to prevent I/O bus contention. Use the Altera/Intel Quartus II design software (legacy support) for synthesis, place-and-route, and timing closure. The 672-BGA package requires careful PCB layout with microvia or via-in-pad technology for reliable assembly.

The device integrates 68,416 logic elements, 250 M4K RAM blocks totaling approximately 1,152,000 bits of embedded memory, and 622 maximum user I/O pins, fabricated on a 90 nm low-k CMOS process. It is specified for commercial temperature operation (0C to +85C) and is supplied in lead-free (Pb-free) packaging. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs) connected by a programmable interconnect fabric. FPGAs occupy the highest tier of the digital logic hierarchy: gate array -> programmable logic device (PLD) -> complex programmable logic device (CPLD) -> FPGA -> SoC FPGA. Unlike microcontrollers that execute firmware sequentially, FPGAs implement true hardware parallelism, making them ideal for high-throughput DSP, custom interfacing, and prototyping ASICs. The Cyclone II family targets cost-sensitive, high-volume applications where ASIC NRE costs cannot be justified. Key features of the EP2C70F896C6N include 4,276 configurable logic blocks (CLBs), up to 150 embedded 18x18 multipliers, four phase-locked loops (PLLs) for clock management, and support for external memory interfaces including DDR, DDR2, SDR, and QDRII SRAM. Configuration is loaded via passive serial (PS), active serial (AS), or JTAG modes, with configuration data stored in an external serial configuration device. The architecture combines a four-input look-up table (LUT)-based logic element with embedded memory and multiplier blocks, allowing designers to balance logic, RAM, and DSP resources on a per-design basis. The 622 user I/O pins are organized into eight I/O banks, each supporting a mix of single-ended standards (LVTTL, LVCMOS, PCI, SSTL) and differential standards (LVDS, RSDS, mini-LVDS) at user-selectable voltages. Typical applications include industrial motor control and video processing, telecommunications line cards, automotive driver assistance prototypes, and educational or research platforms. The high logic density makes it well suited to mid-range ASIC prototyping and signal processing pipelines. The 896-ball BGA package, however, requires multi-layer PCB design and controlled-impedance routing, increasing board complexity. When designing with this device, pay close attention to the four PLL placement constraints: each PLL must reside in a corner of the die and supports only specific clock input pins. Thermal dissipation is moderate for an FPGA of this size, but designers should plan copper pour and thermal vias for production environments where ambient temperature may exceed 70C.

The Intel (formerly Altera) EP2C70F896C7 is a member of the Cyclone II FPGA family built on a 90 nm low-k dielectric CMOS process, offering 68,416 logic elements, 1,152,000 bits of embedded RAM, and 622 user I/O pins in a 896-ball FineLine BGA package. The 'C7' speed grade designates the commercial temperature range with the slowest speed bin, while the 'F896' suffix marks the 896-pin FBGA package. Cyclone II is positioned as a low-cost, high-volume programmable logic family targeting cost-sensitive applications where complex FPGAs are over-specified. A Field Programmable Gate Array (FPGA) is a semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnects, and dedicated hardware blocks such as multipliers and memory. FPGAs sit in the programmable logic hierarchy below ASICs and below their higher-end kin (Stratix, Arria, Cyclone V/10) for cost-optimized designs. Cyclone II devices are SRAM-based, meaning the configuration bitstream is loaded from an external flash at each power-up and can be re-programmed in-system indefinitely. Key features include 68,416 logic elements distributed across four- and six-input look-up tables (LUTs), 4,608 Kbits of M4K embedded memory blocks supporting true dual-port operation with parity bits, 150 embedded 18 x 18 multipliers for DSP operations, and 16 global clock networks with up to four PLLs per device. Each I/O pin supports multiple I/O standards including LVTTL, LVCMOS, PCI, SSTL, HSTL, LVDS, and RSDS. The configuration interface supports JTAG (IEEE Std 1149.1), Passive Serial (PS), Fast Passive Parallel (FPP), and Active Serial (AS) modes via the dedicated configuration pins. Cyclone II devices internally operate at 1.2 V core supply with separate VCCIO banks for I/O voltage flexibility, supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V interfacing. The 150 18 x 18 multipliers can be combined into larger multiplier structures such as 36 x 36 signed multipliers, enabling FIR filters, FFT butterflies, and image-processing pipelines without consuming general-purpose logic. PLLs provide clock multiplication, division, phase shifting, and duty-cycle control, simplifying board-level clock tree design. Typical applications include industrial motor control and servo drives, video surveillance and image processing, automotive infotainment, telecommunications line cards, low-cost prototyping of ASICs, and embedded control with soft processors such as Nios II. The 896-FBGA package with 622 user I/Os suits designs that demand high off-chip bandwidth, such as DDR/DDR2 memory controllers, video frame buffers, and multi-channel data acquisition. Cyclone II is a mature family often chosen for long-life-cycle industrial, medical, and military programs. When designing with this part, use the Quartus II design software (version 13.0 sp1 or earlier is the last fully-supported release). Plan power sequencing carefully because Cyclone II requires VCCINT (1.2 V) and VCCIO banks to ramp within datasheet-specified monotonicity, and confirm configuration mode and flash device selection before layout. Always use IBIS models for signal-integrity simulation of DDR2/LVDS links. This page consolidates distributor pricing, drop-in package-equivalent parts, and practical Quartus II design notes that complement the official Altera Cyclone II handbook.

FPGAs sit in the programmable-logic hierarchy between fixed-function ASICs (highest performance, highest NRE) and microcontrollers (lower performance, software-defined). The Cyclone II family in particular targets the low-cost segment, providing a balance of logic density, embedded multipliers, and block RAM for DSP, video, and embedded control designs. Key features of the EP2C70F896C7K include 68,416 logic elements, 4,488 Kbits (approximately 561 Kbytes) of embedded memory in M4K blocks, 150 embedded 18x18 multipliers, four phase-locked loops, and 622 maximum user I/O pins. The device supports configuration through passive serial, active serial, JTAG, and Altera Fast Passive Parallel modes, giving designers flexibility in production and field programming. Architecturally, the Cyclone II LE combines a 4-input look-up table (LUT) with a programmable register, feeding into a rich routing fabric with predictable timing. M4K memory blocks can be configured as true dual-port, simple dual-port, or single-port RAM, ROM, or shift registers, while embedded 18x18 multipliers enable single-cycle DSP operations at up to 250 MHz, which is well suited for video processing, motor control, and software-defined radio front ends. Typical applications include industrial automation controllers, video surveillance and image processing, automotive infotainment, communications infrastructure, and consumer electronics such as flat-panel displays and set-top boxes. The low static and dynamic power consumption of the 90-nm process also makes the EP2C70 a common choice for portable and thermally constrained designs. When designing with this FPGA, pay attention to I/O bank voltage grouping because mixing incompatible I/O standards in the same bank can cause contention. Plan the configuration scheme (AS, PS, JTAG) early, since the EPCS serial configuration device must be sized for the bitstream of the chosen design. Finally, verify power budgeting using the Altera PowerPlay Early Power Estimator before PCB layout.

The Intel (Altera) EP2C8AF256I8N is a low-cost Cyclone II Field Programmable Gate Array built on a 90 nm CMOS process, delivering 8,256 logic elements, 182 user I/O pins, and 165,888 bits of embedded RAM in a 256-ball FineLine BGA package with industrial temperature grade (-40C to +100C). The device is part of Intel's legacy Cyclone II family targeting high-volume, cost-sensitive digital logic integration. What is an FPGA? A Field Programmable Gate Array is a programmable logic device that lets engineers implement arbitrary digital circuits after PCB fabrication, in contrast to an ASIC (Application-Specific Integrated Circuit) whose function is fixed at the foundry. FPGAs sit in the broader taxonomy of programmable logic devices (PLDs) > FPGAs > SRAM-based FPGAs > low-cost FPGAs, alongside SPLDs and CPLDs. Cyclone II occupies the entry-level/low-density node of this hierarchy, optimized for cost-per-logic-element rather than raw performance. Key features include 36 embedded 18x18 multipliers (typical), up to 4 PLLs for clock management, support for external memory interfaces including DDR/DDR2/QDRII SRAM, and configuration via passive serial, active serial, or JTAG. The 1.2 V core supply with separate VCCIO banks (1.5 V / 1.8 V / 2.5 V / 3.3 V) allows mixed-voltage I/O without level shifters, which is a major advantage over older FPGAs with fixed I/O standards. The Cyclone II architecture combines a 2-D row/column interconnect with embedded multiplier blocks and M4K RAM blocks (4 Kbit each, true dual-port), enabling efficient DSP and buffer implementations. 90 nm process technology balances leakage and performance for the target industrial and consumer segments. Typical applications include industrial motor control, video processing bridges, low-cost PCIe endpoints, protocol bridging (UART/SPI/I2C aggregation), and LED display controllers. Designers choose Cyclone II when unit cost matters more than absolute logic density or transceiver speed. Design consideration: PCB layout for a 256-ball FBGA demands 4 to 6 layer stackups with matched-impedance routing for clock and high-speed I/O. The I suffix in the part number denotes the industrial temperature range, which is the appropriate selection for non-automotive applications operating between -40C and +100C.

It is built on a 90 nm low-k dielectric CMOS process, supports hot-socketing, and is offered in a commercial temperature grade, making it a flexible platform for high-volume cost-sensitive digital designs. The device also embeds up to 36 embedded 18x18 multipliers (typical Cyclone II EP2C8 configuration) for DSP-centric signal processing tasks. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device that allows engineers to implement arbitrary digital logic functions through a sea of configurable logic blocks, embedded memory, and routing resources that are post-fabrication programmed via an SRAM configuration bitstream. FPGAs sit between fixed-function ASICs (high NRE, low unit cost) and discrete logic (flexible but bulky), and within the broader semiconductor taxonomy they belong to programmable logic devices (PLDs) within the digital logic IC category. Cyclone II specifically targets the low-power, low-cost segment where FPGAs previously could not compete with microcontrollers or DSPs on price. Key features of the EP2C8F256C6 include 8,256 logic elements, 36 embedded 18x18 multipliers (typical), 165,888 RAM bits organized into M4K memory blocks, 182 user I/O pins distributed across multiple I/O banks, 4 phase-locked loops (PLLs) for clock management, support for LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards, and configuration via active serial (AS), passive serial (PS), or JTAG interfaces.

The Cyclone II architecture separates logic into Logic Array Blocks (LABs) of 16 logic elements each, with a 4-input look-up table (LUT), carry chain, and register per logic element. The embedded M4K memory blocks can be configured as SRAM, ROM, or FIFO, while the embedded multipliers accelerate DSP functions such as FIR filters without consuming general-purpose logic. Typical applications for the EP2C8F256C6 include industrial motor control, video processing and display bridging, low-cost DSP co-processing, glue logic replacement, communications protocol bridging (UART, SPI, I2C, PCIe soft cores), and educational/development platforms. The combination of moderate logic density, embedded multipliers, and abundant I/O makes it well suited to mid-complexity designs where a microcontroller lacks throughput but a high-end FPGA is over-spec and over-budget. When designing with this device, ensure that configuration mode (AS/PS/JTAG) is selected to match your system's boot topology, and verify I/O bank voltage compatibility for mixed-voltage interfaces. The 256-FBGA package requires a 1.0 mm or finer pitch PCB land pattern and reflow profile compliant with JEDEC J-STD-020 moisture sensitivity level handling.

The Intel (formerly Altera) EP2C8F256C7 is a low-cost Cyclone II field-programmable gate array (FPGA) built on a 90 nm CMOS process, offering 8,256 logic elements, 182 user I/Os, and 165,888 bits of embedded RAM in a 256-ball FineLine BGA (FBGA-256) package. The device operates across commercial temperature grades and supports up to 250 MHz internal operation with embedded multipliers and a four-phase PLL for clock management. An FPGA (Field-Programmable Gate Array) is a semiconductor device whose logic fabric, interconnect, and I/O are configured by the customer after manufacture. FPGAs sit in the broader hierarchy of programmable logic devices (PLD) alongside CPLDs, and they occupy the middle ground between fixed-function ASICs and software-driven processors — offering hardware parallelism, deterministic timing, and the ability to re-spin logic without respinning silicon. The Cyclone II family specifically targets cost-sensitive, high-volume applications where designers need the flexibility of FPGA fabric without paying the silicon-area premium of high-end FPGAs. Key features include 8,256 logic elements (LEs), 36 embedded 18x18 multipliers, 165,888 bits (about 20 Kbytes) of M4K embedded memory blocks, two PLLs for clock multiplication and phase shifting, and 182 maximum user I/O pins supporting LVDS, LVTTL, LVCMOS, SSTL, and PCI I/O standards. Configuration is supported through JTAG, Active Serial (AS), Passive Serial (PS), and Fast Passive Parallel (FPP) modes. The device is supported by the Quartus II design software. Architecturally, the Cyclone II family uses a 1.2 V core supply with separate VCCIO banks for mixed-voltage I/O, allowing the FPGA to bridge between 1.5 V, 1.8 V, 2.5 V, 3.3 V, and differential I/O domains on the same die. The fabric consists of 4-input look-up tables arranged in logic array blocks (LABs), with dedicated routing, embedded multiplier blocks for DSP, and M4K memory blocks that can be configured as RAM, ROM, or FIFO. The 'C7' speed grade denotes a specific Fmax bin relative to other Cyclone II speed grades. Typical applications include industrial motor and motion control, video processing and display bridges, telecommunications line cards, low-cost prototyping for ASIC replacement, and educational / DSP development kits. The 256-FBGA package provides sufficient I/O count for memory-bus and parallel-data interfaces while still being hand-solderable with reflow and hot-air rework for prototypes. Design considerations include careful decoupling of the 1.2 V core and VCCIO bank supplies, length-matched routing for LVDS pairs, and management of the four PLL power pins. The device is in the mature phase of its lifecycle — designers should verify long-term availability before committing to high-volume production.

EP2C8F256C7N - Cyclone II FPGA 8K LE 182 I/O | Altera

The Altera EP2C8F256C7N is a Cyclone II Field Programmable Gate Array (FPGA) that integrates 8,256 logic elements, 165,888 RAM bits, and 182 user I/Os in a 256-ball LBGA package. This Pb-free (N) version uses speed grade 7 and a commercial temperature grade, delivering a low-cost, low-power programmable platform for high-volume applications. An FPGA is an integrated circuit whose logic fabric can be reprogrammed after manufacturing, allowing hardware designers to implement custom digital functions, parallel processing datapaths, and glue logic without committing to an ASIC. FPGAs sit above simple programmable logic devices (CPLDs) and below custom silicon, offering flexibility and rapid iteration for communications, industrial, video, and test systems. Within the Altera programmable logic family, Cyclone II was optimized for cost-sensitive applications. The EP2C8F256C7N provides 8,256 logic elements for combinatorial and sequential logic, 165,888 bits of embedded RAM for FIFOs and buffers, and 182 user I/Os configurable for LVTTL, LVCMOS, and other I/O standards. The 256-ball FineLine BGA package keeps board area small while enabling 182 user I/O connections on a low-cost four-layer PCB. Its commercial temperature grade covers typical indoor/consumer installations, and the N suffix indicates lead-free, RoHS-friendly finish. Altera/Intel Cyclone II FPGAs use a predictable architecture with embedded memory, dedicated carry chains, global clocks, and configuration from external serial configuration devices. The speed grade 7 bin occupies a middle point in the family, offering adequate timing performance for mainstream control and DSP-oriented functions while reducing cost relative to faster -6 devices. This architecture is supported in Intel/Altera Quartus for synthesis, fitting, and timing analysis. Typical applications include industrial motor control, video frame capture, test-and-measurement front ends, and communication line cards. In an image-processing design, for instance, the 182 I/Os can interface with CMOS image sensors and memory buses while the embedded RAM buffers pixel lines for filtering. The high usable I/O count makes the EP2C8F256C7N a universal bridge between mixed-signal front ends and digital back ends. A key design consideration is the selection of power supplies: separate the core rails, I/O rails, and PLL supplies with adequate decoupling, and follow Intel/Altera pin-connection guidelines for the 256-LBGA ball map. If RoHS compliance is required, avoid the leaded-solder C7 variant and choose the N version featured here. This page provides distributor pricing, same-family drop-in alternatives, and practical FPGA design notes that supplement the manufacturer Cyclone II datasheet, helping engineers compare parts, verify availability, and plan configuration and power delivery.

EP2C8F256C8 - Cyclone II FPGA, 8K LEs, 256-LBGA | Intel (Altera)

The Intel (formerly Altera) EP2C8F256C8 is a low-cost Cyclone II Field Programmable Gate Array delivering 8,256 logic elements, 165,888 bits of embedded RAM, and 182 user I/O pins in a 256-ball FineLine BGA (LBGA) package. It is built on a 1.2 V, 90 nm SRAM process and supports commercial-temperature (C8) operation at 0 °C to +85 °C. A Field Programmable Gate Array (FPGA) is a semiconductor device whose digital logic, interconnect, and I/O behavior are defined by user-supplied configuration data rather than at the fab. FPGAs sit at the top of the programmable logic taxonomy: programmable logic -> PLD -> CPLD -> FPGA, and they are widely used as glue logic, accelerator fabric, and DSP co-processors alongside microcontrollers and ASICs. The Cyclone II family specifically targets cost-sensitive high-volume applications such as consumer electronics, industrial control, and display bridging. Key features of the EP2C8F256C8 include 8,256 logic elements (LEs), 165,888 bits (~20 Kbytes) of embedded M4K memory blocks, 36 embedded 18 x 18 multipliers for DSP operations, four phase-locked loops (PLLs) for clock management, and 182 maximum user I/O pins. The device supports multiple I/O standards including LVTTL, LVCMOS, PCI, SSTL, and LVDS, providing flexibility for mixed-voltage system designs. Configuration is via active serial (AS), passive serial (PS), or JTAG interfaces, allowing fast prototyping and field updates. Architecturally, Cyclone II FPGAs use 4-input look-up tables (LUT4) and a routing fabric optimized for the 90 nm process node. The M4K memory blocks can be configured as RAM, ROM, or FIFO with true dual-port capability, and the embedded multipliers handle DSP tasks such as FIR filters and FFT butterflies without burning logic resources. The four PLLs provide clock multiplication, division, phase shifting, and zero-delay buffering, which simplifies board-level clock tree design. Typical applications include industrial motor control, video processing and display bridges, automotive infotainment pre-processing, low-cost ASIC prototyping, communications line cards, and portable consumer devices. The wide I/O count and embedded DSP blocks make the EP2C8F256C8 especially well suited for parallel sensor aggregation and mid-density glue-logic functions. Designers should note that the Cyclone II family is a mature node - designers targeting new designs should evaluate the current Cyclone IV/V/10 families for active support. When designing with this device, ensure that the configuration mode pins are pulled to the correct state at power-up and that the JTAG chain is properly terminated to avoid boundary-scan failures. The 256-LBGA FineLine BGA package requires careful PCB layout to manage routing density and thermal dissipation. This page synthesizes distributor pricing, drop-in alternatives within the Cyclone II family, and practical design notes not found in the manufacturer datasheet alone.
