EP2C8F256C8N - 8K Logic Elements FPGA | Altera | Embedded Logic

Altera EP2C8F256C8N is a Cyclone II field-programmable gate array containing 8,256 logic elements, 165,888 memory bits, and 182 programmable I/O, supplied in a 256-LBGA package. Its configurable logic and embedded memory support digital control, interface bridging, protocol handling, and glue-logic applications where a fixed ASIC is unnecessary. The FPGA is identified as a 3.3 V device in available comparison information, and exact operating limits must be confirmed from the manufacturer datasheet before design release. A field-programmable gate array is an integrated circuit whose logic functions are defined through configuration rather than fixed wafer-level interconnect. Within the semiconductor hierarchy, the EP2C8F256C8N belongs to FPGA and CPLD devices, which are programmable logic ICs. An FPGA typically combines configurable logic blocks, routing resources, I/O elements, and embedded memory. This flexibility allows engineers to revise functionality, correct design errors, or consolidate several support functions into one device. The principal verified parameters are 8,256 logic elements and 165,888 bits of embedded memory. The device also exposes 182 I/O according to the DigiKey and Heisener listings. The 256-LBGA package provides a large, fine-pitch BGA interface suitable for board designs with substantial external connectivity. Configuration is nonvolatile in the deployment sense because the programmed logic is loaded into the device, but the supplied search data does not state the exact configuration interface, supported memory mode, or startup behavior. Cyclone II devices are suited to datapath, state-machine, communications-control, and embedded system integration functions. The 8,256-logic-element capacity is appropriate for medium-complexity logic, while the 182 I/O count supports multiple buses and peripheral interfaces. Exact logic performance depends on routing, implemented architecture, speed grade, I/O standards, and power supply conditions, none of which are fully specified in the supplied evidence. Typical uses include industrial control, test equipment, image-processing front ends, communications controllers, and educational or legacy FPGA platforms. Its value is strongest when programmability, rapid iteration, and interface consolidation matter more than the very highest logic density. Because the part belongs to an established legacy family, buyers should verify lifecycle status, available configuration support, and long-term supply requirements before new production commitments. Designers should validate the official pin assignment, configuration schematic, decoupling network, supported I/O standards, clock topology, and thermal layout against the manufacturer documentation. The available web material provides basic identity, capacity, I/O count, and package information but does not contain enough authoritative detail to safely invent all missing electrical characteristics. This page combines verified distributor facts, same-package cross-reference evidence, procurement signals, and practical selection guidance without presenting unsupported specifications as datasheet values.

It is a lead-free, RoHS-compliant variant of the EP2C8 family, providing up to 182 user I/O pins with 4 phase-locked loops and a maximum user flash memory of 0 Kbits. The device operates from a 1.15V to 1.25V core supply with 3.3V/2.5V/1.8V/1.5V LVCMOS/LVTTL I/O support. A field-programmable gate array (FPGA) is a semiconductor integrated circuit built around a matrix of configurable logic blocks (CLBs) connected by programmable interconnect. FPGAs belong to the broader category of programmable logic devices (PLDs), which sit within the integrated circuit (IC) hierarchy alongside ASICs, microcontrollers, and DSPs. Cyclone II FPGAs specifically target cost-sensitive, high-volume applications and represent the second generation of Altera's low-cost FPGA family. Key features of the EP2C8F256CXNAA include 8,256 logic elements at 90 nm process technology, 36 M4K RAM blocks (4,608 bits each) totaling 162 Kbits, 18 dedicated 18x18 hardware multipliers for DSP operations, and 4 PLLs for clock management. The device supports configuration via active serial (AS), passive serial (PS), and JTAG modes, with 0 Kbits of on-chip user flash memory. Its 256-ball FBGA package uses a 1.0 mm ball pitch and is RoHS compliant. Architecturally, Cyclone II FPGAs use a lookup-table (LUT)-based logic fabric with embedded memory columns and multiplier blocks distributed across the die. The four PLLs support clock multiplication, division, phase shifting, and external clock output, enabling complex multi-clock domain designs. The 18x18 multipliers accelerate DSP functions such as FIR filters, FFTs, and video processing without consuming general-purpose logic resources. Typical applications include digital signal processing, video processing pipelines, industrial control and factory automation, communications protocol bridging, motor control, and consumer electronics prototyping. The combination of low unit cost, moderate logic density, and integrated DSP blocks makes the EP2C8 ideal for glue logic replacement, custom peripheral interfacing, and parallel processing tasks. A specific use case is LED video wall controllers, where the 18 multipliers handle brightness/color scaling and the 162 Kbits of RAM buffer scan-line data. When designing with this part, pay close attention to the four independent PLL blocks - they require dedicated power pins (VCCA_PLL) and ground isolation, and each PLL has a dedicated analog supply of 1.2V. The 256-FBGA package is a wirebond BGA with 1.0 mm pitch, requiring PCB design with microvia technology (not compatible with 6/6 mil standard 2-layer boards).

EP2C8F256I6N

EP2C8F256I6N - Cyclone II FPGA, 8256 LEs, 256-BGA | Intel

The Intel (formerly Altera) EP2C8F256I6N is a Cyclone II family Field Programmable Gate Array (FPGA) housed in a 256-ball FineLine BGA (FBGA-256) package. The device integrates 8,256 logic elements organized into 540 logic array blocks (LABs), 165,888 bits of on-chip embedded RAM (M4K blocks), and up to 182 user I/O pins, all fabricated on a low-power 90 nm CMOS process with a 1.2 V core supply and a maximum internal clock frequency rated to 402 MHz. The "I6" speed grade in this datasheet designation denotes the industrial operating range (-40 °C to +100 °C junction), while the "N" suffix indicates a lead-free, RoHS-compliant package. What is an FPGA? An FPGA (Field Programmable Gate Array) is a semiconductor device whose digital logic fabric, routing, and I/O behavior are defined by a user-supplied configuration bitstream rather than at the factory. FPGAs sit at the top of the programmable logic hierarchy (FPGA -> programmable logic -> digital IC -> semiconductor) and are used wherever time-to-market, hardware parallelism, or in-field reconfigurability matters. The Cyclone II family was positioned as Altera's low-cost, high-volume FPGA, competing with Xilinx Spartan-3 in applications such as digital signal processing, video bridging, motor control, and glue-logic consolidation. Key features of the EP2C8F256I6N include 36 embedded 18 × 18 hardware multipliers that support DSP blocks at up to 250 MHz, four phase-locked loops (PLLs) for clock management, and support for external memory interfaces including DDR, DDR2, SDR, and QDRII SRAM. The 256-pin FBGA package provides a 1.00 mm ball pitch and uses the industrial temperature grade for harsher environments. Compared with newer Cyclone IV/V parts, the EP2C8F256I6N trades static power for low unit cost, making it attractive for cost-sensitive, proven designs. In practice the EP2C8F256I6N is used in industrial motor drives, video capture and display pipelines, software-defined radio front-ends, low-density ASIC prototyping, and embedded control boards that require parallel DSP. Its 165 Kbits of block RAM and 18 × 18 multipliers allow moderate-throughput FIR filters and FFTs without external memory for coefficient storage. Designers should review the I/O bank voltage and pin assignment tables in the Cyclone II Device Handbook before layout, since each of the eight I/O banks can be powered independently between 1.5 V and 3.3 V. Configuration modes include JTAG, Active Serial, and Passive Serial, and the Quartus II (or later) toolchain is required for synthesis, fitting, and bitstream generation.

The 'I' suffix denotes an industrial temperature range version and the '8' suffix identifies the speed grade. It is a low-cost, high-volume programmable logic device suited for communication, video, and industrial applications that require post-assembly logic changes and flexible I/O. An FPGA is a semiconductor device containing programmable logic blocks, embedded memory, and programmable interconnects that can be configured after manufacturing. The Cyclone II family sits in Intel/Altera's mainstream programmable logic portfolio between MAX CPLDs and high-end Stratix devices. In product hierarchy terms, EP2C8F256I8 is an FPGA -> programmable logic device -> integrated circuit. Engineers configure the logic array using hardware description languages such as Verilog or VHDL, then download a configuration bitstream through active serial, passive serial, or JTAG interfaces. EP2C8F256I8's 8,256 logic elements provide approximately 516 logic array blocks for custom logic functions. The 165,888 RAM bits are organized in M4K memory blocks and can implement FIFOs, small packet buffers, or dual-port memories for data path applications. The 182 user I/O balls support the flexible I/O levels commonly used for memory buses, backplane interfaces, and video data paths. The 256-ball FineLine BGA form factor keeps the design compact while preserving routing access for multiple I/O banks. Because this is a Cyclone II low-cost family device, it is often paired with serial configuration devices and external memories rather than used as a processor-centric SoC. The industrial temperature option is valuable for equipment installed in uncontrolled environments such as factory floors, base stations, and outdoor signage. The FPGA's reconfigurability also allows field updates through secure or partial reconfiguration flows, which reduces service cost over the product lifetime. Typical applications include industrial motor-control logic, video frame grabbers, protocol bridging between Ethernet and custom buses, and test instruments that need a flexible I/O front end. The 182 I/O pins make it practical to connect to multiple ADCs, DACs, memories, and transceivers in the same design. With 165,888 bits of on-chip RAM, moderate packet buffering and line-rate FIFO functions can be implemented without adding an external SRAM. When designing with EP2C8F256I8, pay attention to the core and I/O power supply rails, configuration voltage requirements, and bypass capacitor placement. The FPGA must be configured from an external configuration device or host after power-up; selecting AS or JTAG mode affects the bill of materials and manufacturing test flow. Keep the configuration clock and data signals clean and short to avoid bitstream corruption during production programming.

It contains 8,256 logic elements, 182 user I/O pins, 36 embedded 18x18 multipliers, and 165,888 bits of embedded RAM, providing a balanced resource mix for cost-sensitive programmable-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 engineers can reconfigure in the field using an HDL description. Within the broader taxonomy, FPGAs sit alongside CPLDs, microcontrollers, and ASICs as programmable-logic devices; FPGAs are distinguished by high logic density, on-chip memory, DSP blocks, and (in newer families) hardened transceivers. The Cyclone II family targets volume, low-static-power applications such as consumer electronics, industrial control, and display bridging. Key features of the EP2C8F256I8K include support for multiple single-ended I/O standards (LVTTL, LVCMOS, PCI, SSTL, LVDS), up to four PLLs with up to eight outputs for clock management, configurable JTAG boundary-scan, and on-chip bit-stream decryption for design IP protection. The device operates from a 1.2 V core supply with separate VCCIO banks for I/O flexibility, and its commercial-grade -40 °C to +100 °C junction temperature range suits industrial enclosures. Cyclone II devices are SRAM-based and require an external configuration memory, typically an EPCS or EPCQ serial flash. Typical applications include video processing bridges, motor and motion control, industrial protocol converters (RS-485, CAN, Modbus), low-density DSP pre-processing, LED display controllers, and education or evaluation platforms. The EP2C8F256I8K is also a popular choice for legacy design maintenance because it combines a familiar Quartus II development flow with abundant reference designs. When designing with this device, plan power sequencing for VCCINT (1.2 V) and VCCIO banks carefully and respect the 90 nm SRAM volatile-configuration requirement by selecting a robust serial configuration flash. For new designs, evaluate the Cyclone IV or Cyclone V families first for lower static power; for drop-in board reuse of an existing Cyclone II layout, the EP2C8F256I8K remains a reliable choice.

A field-programmable gate array (FPGA) is an integrated circuit whose digital fabric can be configured after manufacturing by loading a bitstream. Unlike a fixed-function ASIC or microcontroller, an FPGA lets a designer implement parallel hardware logic such as counters, state machines, buses, and DSP functions and revise that logic in the field. The EP2C8Q208C7 belongs to Altera's Cyclone II family, a low-cost SRAM-based FPGA line aimed at applications where logic density, I/O count, and unit price must be balanced. Key features that define the EP2C8Q208C7 include 8,256 logic elements, 138 available user I/Os, and 165,888 bits of on-chip RAM. The 208-pin BFQFP package occupies a conventional quad flat pack footprint and can be used in multilayer boards without BGA routing complexity. The suffix C7 indicates a commercial-temperature ordering grade and speed grade 7, and the non-N finish contains lead, so designs requiring RoHS compliance should select the lead-free N version or another green variant. Distributor pages also list the device at 450 MHz, making it appropriate for moderate-speed control and data-path applications. From an architecture perspective, the EP2C8Q208C7 is an SRAM-based FPGA with look-up-table-based logic blocks, embedded memory blocks, and programmable I/O buffers. Configuration data must be loaded into the device at power-up, and the FPGA can be programmed through JTAG or with an external configuration device. Because the device is part of the mature Cyclone II family, design support remains available through Altera/Intel Quartus software, but new designs should confirm tool-version compatibility and lifecycle support before committing. Typical applications include industrial control, protocol bridging, video and image capture, test equipment, and motor-control logic. The 138 user I/O pins allow multiple parallel buses, encoder interfaces, and low-speed communication ports to be connected in one device, while the embedded memory supports small FIFOs and look-up tables. One key design consideration is that the C7 version is not lead-free: if your manufacturing process or target market requires RoHS compliance, use EP2C8Q208C7N or an I-speed/N version. Also provide proper 0.1uF decoupling on all FPGA rails and load the configuration bitstream from the system controller or a serial configuration device. This page synthesizes distributor availability, pricing tiers, drop-in alternatives, and practical design notes for EP2C8Q208C7 with information drawn from Octopart, DigiKey, Mouser, LCSC, and other public sources, complementing the manufacturer Cyclone II documentation.

EP2C8Q208C7N - Cyclone II FPGA, 8256 Logic Elements | Altera

The Altera EP2C8Q208C7N is a Cyclone II field-programmable gate array (FPGA) with 8,256 logic elements, 165,888 total RAM bits and 138 user I/O pins, delivered in a 208-pin BFQFP (PQFP) surface-mount package. It is an SRAM-based programmable logic device intended for low-cost, medium-density systems where hardware functions can be updated in the field. An FPGA is an integrated circuit whose logic fabric is configured after manufacturing rather than being fixed at the factory. In the product hierarchy, the EP2C8Q208C7N is an FPGA, which is a subclass of programmable logic devices and integrated circuits. Designers describe digital logic in an HDL such as Verilog or VHDL, synthesize it, and load the resulting bitstream into the FPGA. Because the device is SRAM-based, the configuration data is lost at power-off and must be reloaded from an external memory or through a JTAG interface at every power-up. From the verified distributor data, the EP2C8Q208C7N provides 8,256 logic elements, 165,888 total RAM bits, and 138 user I/O pins. This resource level supports moderate combinational and sequential logic, small FIFOs, state machines, soft-core processors, and custom peripherals. The 208-BFQFP package gives design teams a reworkable QFP alternative for systems that do not require a fine-pitch BGA. The seven in the ordering code indicates speed grade -7, and the N suffix represents the lead-free package option used by Altera ordering nomenclature. Technically, the Cyclone II family is a 90 nm SRAM-based FPGA architecture. Its logic cells are suited to designs with modest density requirements, while the embedded memory bits allow on-chip buffering without always adding external SRAM. The 138 user I/O pins can be organized into banks for interfacing with standard logic families and bus interfaces. Exact supported I/O standards, PLL details, configuration pin behavior, and timing tables should be confirmed from the manufacturer datasheet; those silicon-level details are not included in the distributor snippets used on this page. Typical uses include industrial motor control, protocol bridging, small video and image-processing pipelines, LED display control, data acquisition, and medical monitoring front ends. Because of its low-cost QFP format and mature tool flow, it is also used in legacy industrial and communications systems where redesign is undesirable. For high-speed or memory-intensive applications, external SDRAM or higher-density FPGAs are more appropriate. When designing with this FPGA, budget a serial configuration device such as an EPCS flash or provide JTAG configuration during production test. Keep power supplies clean and decoupled close to the FPGA package, and verify the I/O bank voltage before connecting external logic. Treat Cyclone II as a mature product family: for new designs, confirm availability and Intel lifecycle support before committing to a production program. This page synthesizes distributor pricing, package and availability data, practical design notes, and drop-in alternatives that are not all stated on a single distributor page, providing a useful companion to the manufacturer datasheet.

Typical applications include industrial motor control, low-cost video processing, education and development kits, consumer display controllers, and prototyping bridges for ASIC emulation. Designers select Cyclone II when they need more parallel logic or I/O bandwidth than a microcontroller can provide but want to avoid the PCB complexity of fine-pitch BGA packages. Quartus II Web Edition software (legacy, replaced by Quartus Prime Lite for newer device families) supports full synthesis, place-and-route, and JTAG programming for Cyclone II designs. When designing with Cyclone II, observe that core 1.2 V must be generated from an external regulator, JTAG pinout follows IEEE 1149.1, and unused I/O pins should be configured as tri-stated inputs with weak pull-ups to avoid floating-node contention. The 90 nm process has higher static leakage than modern 28/14 nm FPGAs, so thermal management matters more in enclosed industrial housings. This page synthesizes distributor pricing, drop-in alternatives within the Cyclone II family, and practical design notes not found in the manufacturer datasheet.

EP2C8T144C8N - Cyclone II FPGA 8256 LE TQFP-144 | Intel

The Intel (formerly Altera) EP2C8T144C8N is a Cyclone II family Field-Programmable Gate Array (FPGA) with 8,256 logic elements, 165,888 bits of embedded RAM, and 85 user I/Os, packaged in a 144-pin TQFP. Built on a 90 nm process, it operates from a 1.15 V to 1.25 V core supply, supports up to two PLLs, and is rated for commercial (0C to +85C) operation. The Cyclone II family extends the original Cyclone low-cost FPGA density range to 68,416 LEs while preserving a low-cost silicon target suitable for high-volume applications. A Field-Programmable Gate Array (FPGA) is a programmable semiconductor device whose logic function is defined after manufacturing by a user-supplied bitstream. FPGAs sit in the broader taxonomy of programmable logic devices (PLDs) -> logic ICs -> integrated circuits -> semiconductors. They are chosen over application-specific integrated circuits (ASICs) when design revisions, parallel processing, or hardware-acceleration flexibility are required. Cyclone II FPGAs specifically balance cost, logic density, and embedded memory for cost-sensitive applications. Key features include 8,256 logic elements organized into 516 configurable logic blocks, 165,888 bits of embedded memory (M4K blocks), up to 182 usable I/O pins (package-limited to 85 on this 144-pin TQFP), embedded multipliers (18x18), two PLLs per device, and Cyclone II configuration via serial or parallel configuration schemes. The 90 nm process technology keeps unit cost low while supporting up to 1.1 Mbits of embedded memory at the family level. The EP2C8T144C8N supports up to 320 MHz internal operation with on-chip PLL clock management. The 144-pin TQFP package is a surface-mount plastic thin quad flat pack without an exposed pad, simplifying PCB assembly but limiting it to moderate thermal dissipation. This device is pin-compatible with the EP2C8T144I8N (industrial temperature grade variant), enabling a single PCB to serve multiple end-market grades. Typical applications include digital signal processing, video bridging, industrial control logic, low-cost ASIC prototyping, consumer electronics glue logic, and embedded display controllers. Designers also use Cyclone II FPGAs as a prototyping step before migrating to higher-density Cyclone III/IV/V parts. When designing with this device, ensure that all VCCINT and VCCIO rails have proper decoupling (0.1 uF plus bulk capacitors per Quartus II pin connection guidelines) and that JTAG configuration pins are accessible for in-system programming. Consider the EP2C5T144C8N for lower-density designs to reduce cost, or migrate upward to EP2C20F256C8N if logic density outgrows the EP2C8.

EP2C8T144I8 - Cyclone II FPGA, 8256 Cells, 144-LQFP | Intel

The Intel (formerly Altera) EP2C8T144I8 is a low-cost, low-power Cyclone II Field-Programmable Gate Array (FPGA) with 8256 logic elements, 165888 bits of embedded RAM, and 85 user I/Os, housed in a 144-pin LQFP (TQFP-144) surface-mount package. It is specified over the industrial temperature range (-40C to +85C, I8 speed grade) and supports a core supply of 1.2 V with multiple I/O bank voltages for mixed-voltage system integration. A Field-Programmable Gate Array (FPGA) is a reconfigurable semiconductor device built from an array of programmable logic blocks, programmable interconnect, and embedded memory blocks that can be customized by the end user after manufacturing. Cyclone II belongs to the low-cost programmable logic -> FPGA -> programmable logic device -> integrated circuit hierarchy, designed to deliver ASIC-like density at ASIC-like unit cost for high-volume applications. FPGAs occupy the same role in system architecture as an ASIC but offer in-field reconfigurability, parallel logic execution, and deterministic hardware timing. Key features of the EP2C8T144I8 include up to 402.58 MHz internal operation, 18 embedded 18x18 multipliers suitable for DSP functions, and up to 516 configurable logic blocks (CLBs) implemented using a 90-nm CMOS process. The device also supports up to 165888 RAM bits organized into M4K memory blocks, and offers four phase-locked loops (PLLs) for clock management and frequency synthesis. The 144-LQFP package uses plastic gull-wing leads and a 1.0 mm pitch, which is compatible with low-cost PCB manufacturing. Typical applications include industrial motor control, video processing pipelines, communication protocol bridging, low-cost DSP functions, and glue logic replacement. The Cyclone II family is widely used in cost-sensitive designs where designers want FPGA flexibility but must meet tight BOM targets. When designing with the EP2C8T144I8, ensure that all four PLL analog supply pins (VCCA_PLL) are properly decoupled and that the JTAG chain is accessible in production for in-system programming. Multiple I/O voltage banks allow mixed-voltage interfacing (3.3 V, 2.5 V, 1.8 V, 1.5 V) within the same device without external translator ICs.

EP2C8T144I8N - Cyclone II FPGA, 8K LEs, 144-TQFP | Intel

The Intel (formerly Altera) EP2C8T144I8N is a low-cost Cyclone II Field-Programmable Gate Array (FPGA) built on a 90 nm low-k dielectric process and offered in a 144-pin Thin Quad Flat Pack (TQFP) package. The device integrates 8,256 logic elements (LEs), 165,888 bits of embedded RAM organized as 36 M4K memory blocks, and 85 user I/O pins with support for multiple I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and PCI. An FPGA (Field-Programmable Gate Array) is a reconfigurable digital integrated circuit whose logic fabric, interconnect, and I/O can be customized by the end user after manufacture using a hardware description language such as Verilog or VHDL. Within the broader semiconductor taxonomy, FPGAs sit at the top of the programmable-logic hierarchy above CPLDs (Complex Programmable Logic Devices) and below fixed-function ASICs (Application-Specific Integrated Circuits). The Cyclone II family specifically targets low-density, cost-sensitive applications where ASIC non-recurring engineering cost is not justified. Key specifications include 36 embedded 18x18 multipliers supporting up to ~250 MHz DSP performance, two PLLs for clock management, configuration via active serial (AS), passive serial (PS), or JTAG, and an industrial temperature range of -40C to +100C. The 144-TQFP package exposes 85 user I/O pins and supports 1.2 V core operation with multi-voltage I/O banks at 1.5 V, 1.8 V, 2.5 V, or 3.3 V. The Cyclone II architecture pairs 4-input look-up tables (LUTs) with embedded memory blocks to implement logic, DSP, and simple microcontroller functions on a single chip. The part is supported by the Quartus II design toolchain, which provides synthesis, place-and-route, timing analysis, and bitstream generation for configuration via a JTAG header or EPCS configuration flash. Typical applications include industrial motor and motion control, video processing bridges, low-density communications glue logic, education and FPGA training platforms, and prototype ASIC replacement. Cyclone II devices were widely adopted in mid-2000s designs and remain useful for long-lifecycle industrial systems where re-qualification costs discourage migration to newer families. When designing with this part, ensure the core decoupling network follows the Cyclone II handbook guidelines - typically 0.1 uF and 10 uF capacitors near every VCCINT/VCCIO pin pair. Configuration mode selection via MSEL pins must match the configuration device in use, and unused I/O pins should be set to tri-state with weak pull-up via Quartus device options to minimize in-rush current during configuration.
