The Altera (Intel) EP2C20F256C7N is a Cyclone II Field Programmable Gate Array (FPGA) with 18752 logic elements (LEs), 152 maximum user I/O pins, and 239616 bits of embedded memory, housed in a 256-ball FineLine BGA (FBGA) package. It is fabricated on a 90 nm low-k dielectric CMOS process, operates from a 1.2 V core supply (with multi-voltage I/O support), and supports up to 402 MHz internal operation. What is a Cyclone II FPGA? An FPGA (Field Programmable Gate Array) is a programmable logic device whose logic, interconnects, and I/O cells are defined by user configuration bits rather than hard-wired at the foundry. FPGAs sit in the broader taxonomy of programmable logic devices (PLDs) -> FPGAs -> SRAM-based FPGAs -> Cyclone family -> Cyclone II family. Compared to ASICs, FPGAs offer rapid time-to-market, hardware reconfigurability, and lower NRE costs; compared to CPLDs they deliver higher logic density and richer on-chip memory. Key features include 52 embedded 18x18 multipliers (approx. 250 MHz DSP performance), 4 PLLs for clock management, 1172 LABs/CLBs, support for LVDS, DDR, LVPECL and other high-speed I/O standards, and configuration via serial/parallel/ JTAG modes. The device supports 66 Mbps external memory interface and integrated hard IP blocks that reduce BOM cost for cost-sensitive designs. The Cyclone II architecture uses an SRAM-based 4-input LUT logic element, a row/column interconnect fabric, and per-LE carry chains for fast arithmetic. The 90 nm process and 1.2 V core voltage position this part for low-power, high-volume applications; embedded memory blocks (M4K) total ~240 Kbits and can be configured as RAM, ROM, or FIFO with ECC support. Typical applications include industrial motor control, video processing, automotive infotainment, low-cost ASIC prototyping, telecom line cards, and consumer electronics displays. Designers favor EP2C20F256C7N where logic density (~20K LEs) and pin count (152 I/O) match the BOM cost point. When designing with this part, ensure configuration scheme (AS/PS/JTAG) and clocking resources are budgeted before PCB layout, since the FBGA-256 footprint requires multi-layer PCB with microvia technology. Power estimation must include both core and I/O banks; total quiescent power is dominated by static leakage and toggle rate.

Built on a 90 nm low-k CMOS process, it delivers 18,752 logic elements organized into 1,172 Configurable Logic Blocks (CLBs), along with 239,616 bits of embedded RAM. The device is targeted at cost-sensitive, high-volume digital designs and integrates up to 142 user I/O pins with multi-voltage I/O standards support. A Field-Programmable Gate Array (FPGA) is a reprogrammable semiconductor device that uses configurable logic blocks (CLBs), programmable interconnect, and I/O cells to implement arbitrary digital circuits. FPGAs sit at the top of the programmable logic hierarchy, above CPLDs and discrete logic, and below ASICs in terms of per-unit cost vs. flexibility. Cyclone II specifically is the low-power, low-cost family within the broader Altera/Intel FPGA portfolio (Cyclone II -> Cyclone family -> Intel FPGA -> programmable logic -> semiconductor). Key features include 4 phase-locked loops (PLLs) for clock management, dedicated 18x18 multipliers, and on-chip memory blocks of M4K type (4,608 bits per block, 52 blocks total). The device supports LVDS, LVTTL, LVCMOS, PCI, and SSTL I/O standards, making it compatible with virtually any digital interface. Dual-purpose configuration pins allow JTAG-based in-system programming via the standard Active Serial (AS) or Joint Test Action Group (JTAG) modes using the Quartus II design software. Cyclone II FPGAs use a 4-input look-up table (LUT) architecture with embedded SRAM configuration cells. The silicon is fabricated in a 90 nm process, providing a balance between logic density, static power, and dynamic performance. The 'C8' speed grade corresponds to a -8 internal commercial speed rating with a maximum internal clock frequency around 402.5 MHz per the device family. Typical applications include digital video processing, industrial motor control, automotive infotainment prototypes, custom peripheral expansion, and glue-logic replacement. The 256-FBGA package with 1.0 mm ball pitch is suitable for reflow-solder assembly on standard 4-layer PCBs.

The Intel (formerly Altera) EP2C20F256C8N is a low-cost Cyclone II Field-Programmable Gate Array (FPGA) featuring 18,752 logic elements (LEs), 239,616 bits of embedded RAM, and 152 embedded 18x18 multipliers, packaged in a 256-ball FineLine BGA (FBGA-256) at 1.2 V core. According to manufacturer material referenced on the Cyclone II device handbook, the device is built on a 90 nm process and supports up to 315 user I/O pins (device-package dependent) with on-board configuration via serial/parallel flash and JTAG. The 'C8' speed grade targets approximately 402 MHz internal operation, while the 'N' suffix indicates lead-free / Pb-free termination. The EP2C20F256C8N extends the Cyclone II family mid-density range between EP2C8 and EP2C35, making it a strong fit for cost-sensitive high-volume designs. What is a Cyclone II FPGA? A Field-Programmable Gate Array (FPGA) is a semiconductor IC whose logic function is defined after manufacturing via a hardware description language (HDL) bitstream. The Cyclone II family sits in the low-cost (non-volatile configuration, external SRAM-based) tier of programmable logic, hierarchically classified as: FPGA -> programmable logic -> logic IC -> integrated circuit -> semiconductor. Compared with CPLDs (which are typically non-volatile and smaller), FPGAs offer higher logic density, embedded multipliers, and block RAM, but require an external configuration memory at power-up. Key features include 18,752 four-input look-up tables (4-input LUTs), 52 M9K memory blocks (~ 52 x 9 Kbit = 468 Kbit raw, with parity overhead yielding 239,616 usable RAM bits), 152 dedicated 18 x 18 hardware multipliers for DSP, four phase-locked loops (PLLs) for clock management, and support for external memory interfaces including DDR/DDR2 SDRAM and QDRII SRAM. The 256-ball FBGA package exposes the device's high-I/O capability with fine-pitch surface-mount routing. Architecture-wise, the Cyclone II device uses a 90 nm CMOS process, 1.15 V to 1.25 V core (VCCINT), and separate VCCIO banks that allow mixed-voltage I/O (1.5 V, 1.8 V, 2.5 V, 3.3 V) on the same die. Embedded multipliers are physically arranged in column blocks adjacent to the LAB (Logic Array Block) rows, enabling deterministic DSP performance independent of routing congestion. The four PLLs support clock multiplication, division, phase shifting, and external feedback for zero-delay buffering. Typical applications include industrial motor control, video processing pipelines, low-cost software-defined radio, consumer display controllers, factory automation, and educational / prototyping platforms. The mid-density 18,752 LE capacity makes it well suited to designs that outgrow CPLDs but do not require the cost of higher-density Cyclone IV or Cyclone V devices. When designing with this device, plan for an external EPCS or EPCQ configuration flash to load the bitstream at power-up, provide proper decoupling on every VCCINT and VCCIO pin per the pin connection guidelines, and verify the package thermal envelope against expected toggle activity. Quartus II Web Edition (legacy) or the latest Quartus Prime Lite Edition supports Cyclone II device compilation. The part is widely available on the secondary market; new designs targeting Intel's modern portfolio should evaluate Cyclone IV E, Cyclone 10 LP, or MAX 10 instead. This page synthesizes distributor pricing, drop-in alternatives from the same Cyclone II family (EP2C20F256C6N, EP2C20F256C7N, EP2C20F256C8) plus verified web-data cross-references (EP2C20F484C6N, EP2C20F484C8), and practical design notes that go beyond the manufacturer handbook.

EP2C20F256I8

EP2C20F256I8 - Cyclone II FPGA 18,752 LE, 256-BGA | Altera

The Altera EP2C20F256I8 is a Cyclone II Field-Programmable Gate Array (FPGA) with 18,752 logic elements, 239,616 bits of embedded RAM, and 152 user I/O pins, delivered in a 256-ball FBGA (256-LBGA) package. It runs from a 1.2 V core supply and is implemented in 90 nm CMOS technology. The "I" in the ordering code denotes industrial temperature grade and the "8" denotes speed grade 8, making this a low-to-mid-density programmable logic device for systems requiring wider operating-temperature margins. An FPGA is an integrated circuit whose logic fabric is configured after manufacturing by loading a configuration bitstream. Instead of executing sequential software, it creates parallel hardware datapaths: designers write HDL, synthesize logic into logic elements, routing and I/O blocks, and configure the device in-system. Cyclone II FPGAs are SRAM-based, so they are volatile and need to reload their bitstream at power-up from flash, a host processor, or an Altera configuration device. In product hierarchy, this part is an FPGA -> SRAM-based FPGA -> mid-range Cyclone II -> Altera programmable logic family. Headline features include 18,752 logic elements, 239,616 RAM bits, and 152 user I/O pins. The 1.2 V core logic family is CMOS, and the 256-ball BGA has a moderate footprint that suits parallel bus designs and controlled-impedance board layouts. The industrial-temperature suffix widens the allowable ambient operating range compared with commercial C-grade siblings. The device supports JTAG and active/passive serial configuration modes, allowing flexible factory programming and in-field updates. Architecturally, Cyclone II places logic in logic array blocks together with embedded memory blocks, and connects the fabric through programmable routing to I/O banks. The 90 nm low-cost process balances density, power, and unit price for cost-sensitive systems. Since Cyclone II is SRAM-based, the non-volatile configuration solution must be selected early; typical choices include an EPC-series configuration device or a host microcontroller that loads the .rbf/.pof image at power-on. Typical applications include industrial control and motor-drive interfaces, communication bridging, video/image preprocessing, test instrumentation, and IoT edge gateways. The 152 I/O pins give designers enough flexibility to connect memories, ADCs, DACs, transceivers, and human-machine-interface peripherals. The 239,616 RAM bits are useful for FIFOs, small line buffers, and coefficient tables, reducing the need for external SRAM in moderate-size designs. Designers should decouple the 1.2 V core rail thoroughly and follow Altera Cyclone II board-layout guidance for the F256 BGA. Because exact current and thermal figures were not included in the fetched distributor data, use the official Cyclone II power calculator and the device handbook to size regulators and heatsinking before production. This page adds distributor context, ordering-code alternatives, and practical design guidance beyond the bare datasheet, helping engineers complete sourcing and design triage more quickly.

FPGAs sit in the programmable logic hierarchy between discrete microcontrollers and fixed-function ASICs, offering hardware-level parallelism for DSP, glue logic, and high-speed interface bridging. The Cyclone II architecture provides four-input look-up tables (LEs), embedded M4K RAM blocks (total 239,616 bits / approximately 117 kbytes), dedicated 18x18 hardware multipliers (up to 52), and four phase-locked loops (PLLs) for clock management. The device supports LVDS, LVTTL, LVCMOS, SSTL, and differential I/O standards, and includes a passive serial, JTAG, or active serial configuration interface. Typical applications include industrial motor control, video processing pipelines, low-cost DSP front-ends, telecom line cards, and consumer electronics prototyping. The Cyclone II family is the second-generation low-cost Altera/Intel FPGA, optimized for high-volume price-sensitive designs where millions of gates are needed but the absolute performance of a Stratix is not required. When designing with this FPGA, attention must be paid to the multi-rail power sequencing (1.2 V core, 2.5 V or 3.3 V PLL analog, and I/O voltage). The 256-FBGA package requires a multi-layer PCB with controlled-impedance traces for high-speed LVDS pairs and proper decoupling to meet signal-integrity requirements. The Quartus II design software (legacy) supports Cyclone II; newer Quartus versions also retain Cyclone II support through device family add-ons.

EP2C20Q240C8

EP2C20Q240C8 - Cyclone II FPGA, 18,752 LE | Intel

The Intel EP2C20Q240C8 is a Cyclone II Field Programmable Gate Array with 18,752 logic elements, 239,616 bits of embedded RAM, 142 user I/O pins, a 1.2 V core supply, 90 nm CMOS technology, and a maximum internal clock frequency around 402.58 MHz, supplied in a 240-pin PQFP (240-BFQFP) surface-mount package. A field-programmable gate array (FPGA) is an integrated circuit whose logic fabric can be configured after manufacturing; the Cyclone II family is Altera/Intel's low-cost, high-volume FPGA line built for logic-intensive but cost-sensitive applications. It sits hierarchically under programmable logic devices and integrates configurable logic blocks, embedded RAM, and I/O elements. Understanding Cyclone II as an FPGA rather than a fixed-function ASIC helps designers recognize that the same EP2C20Q240C8 can be reconfigured in-system for motor control, video processing, or communications bridging simply by loading a new bitstream. Key differentiating specifications of EP2C20Q240C8 include 18,752 logic elements, 239,616 bits of embedded memory, and 142 user I/O pins configured in the 240-pin PQFP. DigiKey and FindIC parametric listings identify a typical internal operating frequency of about 402.58 MHz and a 1.2 V core supply. The Cyclone II family also provides enough logic capacity for soft processors and DSP datapaths while maintaining a low-cost footprint. Because this is a commercial-temperature part, the device is rated for 0°C to +85°C and is intended for equipment that does not require extended industrial temperature operation. The EP2C20Q240C8 is fabricated on a 90 nm CMOS process, which was the mainstream low-cost process node of the Cyclone II generation and accounts for the device's moderate static and dynamic power compared with later families. The part is a member of the 18,752-logic-element Cyclone II density tier; it uses a conventional SRAM-based FPGA architecture that must be configured at power-up from an external configuration device, typically an Altera/Intel EPCS serial flash. The architecture includes row and column routing, I/O buffers, and embedded memory blocks that provide the 239,616 bits used for FIFOs and small buffers. Typical applications include industrial motor control, video and image processing, communications line bridging, and test-and-measurement front ends. In each case, the 18,752 LEs can absorb moderate combinational logic and state machines, while the 142 I/O pins let the FPGA connect to sensors, ADCs, DACs, memory devices, and backplane buses. The 1.2 V core keeps power manageable in fan-cooled or naturally ventilated enclosures, and the commercial temperature range suits many indoor equipment installations. From a design standpoint, budget for a clean 1.2 V core supply, one or more I/O-bank supplies, and a configuration device because EP2C20Q240C8 is usually configured from an EPCS serial flash or through JTAG. Because no N suffix appears in the part number, the package finish is not explicitly identified as lead-free in the available listings; choose EP2C20Q240C8N when lead-free/RoHS assembly is required. This page synthesizes distributor stock and pricing, drop-in same-family alternatives, application guidance, and practical power/configuration notes that are not all collected in the manufacturer datasheet.

It operates from a 1.2 V core supply and is specified for the 0 °C to +85 °C commercial temperature range. The -8 speed grade provides a commonly quoted maximum clock frequency around 402.58 MHz. An FPGA, or field-programmable gate array, is a programmable logic device whose internal logic blocks, routing resources, and I/O elements can be configured after manufacturing to implement arbitrary digital hardware. In the hierarchy of semiconductor logic, an FPGA belongs to programmable logic devices (PLDs), sitting above simple CPLD products and below custom ASICs in capacity and design flexibility. Cyclone II is Altera/Intel's low-cost FPGA family, optimized for cost-sensitive applications that need thousands of reconfigurable logic elements without the non-recurring engineering cost of a custom chip. Key features of the EP2C20Q240C8N include 18,752 logic elements, 239,616 total RAM bits, and a commercial 0 °C to 85 °C operating range. The 240-pin PQFP package provides 142 user I/O pins, which is practical for moderate bus widths, control interfaces, and bridging applications. As a speed-grade -8 device, it targets main-stream cost-optimized designs rather than the fastest timing closure. The 1.2 V core voltage allows low dynamic power, while I/O banks support common single-ended standards such as LVCMOS and LVTTL. The Cyclone II architecture is based on 4-input look-up-table logic elements grouped into logic array blocks, complemented by embedded memory blocks and dedicated clock networks. The 90 nm process and 1.2 V core helped make mid-density FPGAs affordable for industrial and communications equipment during Cyclone II's production life. The EP2C20Q240C8N is configured through SRAM cells, so it requires an external configuration device such as an EPC or EPCS serial device or a JTAG download cable at power-up. Typical applications include industrial motor/motion control, image and video preprocessing, communication bridging, medical front-end processing, and digital-prototyping boards. In these systems, the EP2C20Q240C8N provides deterministic parallel processing and flexible I/O at a lower cost than a larger FPGA. Its QFP package also supports simpler PCB inspection and rework than fine-pitch BGA alternatives. A critical design consideration is the need for clean 1.2 V core power, separate I/O bank voltages, and a proper configuration scheme chosen by the MSEL pins. Because this is a legacy FPGA family, new designs should verify device lifetime, configuration-device availability, and distributor stock before committing to production. This page synthesizes distributor pricing, same-package drop-in alternatives, application guidance, and practical design notes not found in a simple parametric listing.

The device is fabricated on a 90nm low-k CMOS process. Typical applications include video surveillance and image processing pipelines, industrial motor control and factory automation controllers, low-cost wireline/wireless baseband processing, PCI/PCI-X bridge designs, and display controllers. The combination of high logic density, embedded multipliers, and broad memory interface support makes the EP2C35F484C8 particularly well-suited to mid-complexity DSP and control-plane designs. Design consideration: Successful PCB layout requires careful attention to the 484-ball BGA fanout, power distribution (VCCINT 1.2V, VCCIO banked 1.5V/1.8V/2.5V/3.3V), and decoupling. Use a multi-layer PCB with dedicated power and ground planes; place 0.1uF and 10uF decoupling capacitors close to each power pin. The Cyclone II datasheet provides reference board layouts and signal-integrity guidelines that should be followed.

EP2C35F484C8N

EP2C35F484C8N - Cyclone II FPGA, 33K LEs, 484-FBGA | Intel

The Intel (formerly Altera) EP2C35F484C8N is a low-cost Cyclone II family FPGA delivering 33,216 logic elements, 483,840 bits of embedded memory (M4K blocks), and 322 user I/Os in a 484-pin FineLine BGA package. Built on a 90 nm process, it operates from a 1.2 V core supply and supports up to four phase-locked loops with performance rated up to 402 MHz internal operation. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit whose logic function is defined after manufacturing through user programming. FPGAs occupy a unique tier in the digital design hierarchy: more capable than discrete logic (74-series gates) and CPLDs (Complex Programmable Logic Devices), but lower-cost and lower-power than ASICs (Application-Specific Integrated Circuits). They are widely used for glue logic, digital signal processing front-ends, custom peripheral buses, and pre-ASIC prototyping. Within that taxonomy, the Cyclone II series specifically targets cost-sensitive, high-volume applications where every logic element and I/O pin must be maximized per dollar. Key features include 35,000 LEs (the Cyclone II nomenclature counts logical resources slightly above the LE name, equivalent to roughly 33K fully-routed logic elements), up to 483,840 RAM bits arranged in 4-kbit M4K blocks supporting true dual-port operation, and 35 embedded 18x18 multipliers for DSP applications. The device also includes four PLLs and supports LVDS I/O standards on selected pins. The Cyclone II architecture uses a 2D row/column interconnect backed by SRAM configuration memory. Its 90 nm process allows high logic density at low static power. Configuration is loaded from a passive serial, JTAG, or EPCS configuration device. The 484-FBGA package exposes 322 user I/Os, giving designers generous headroom for memory buses, video interfaces, and parallel connectivity. Typical applications include industrial motor control, video processing and display bridges, telecom line cards, low-cost DSP co-processing, and pre-silicon ASIC prototyping. The combination of abundant DSP blocks and external memory interfaces makes it well suited to image-pipeline front-ends. Per the manufacturer datasheet, the EP2C35F484C8N speed grade 8 corresponds to a -8 commercial temperature rating, balancing timing margin against cost. When designing with this device, plan a multi-rail power tree for 1.2 V VCCINT, 3.3 V VCCIO, and PLL analog supplies, with careful decoupling on every VCCIO bank. The 484-FBGA demands a multi-layer PCB with microvia-in-pad stackup; signal integrity on LVDS pairs requires matched-length routing. Although the part is mature, lead-time and lifecycle pressure have shifted many new designs to Cyclone IV or Cyclone V equivalents.

EP2C35F484I6N

EP2C35F484I6N - 33K LE Cyclone II FPGA, 484-FBGA | Intel

The Intel EP2C35F484I6N is a low-cost Cyclone II field-programmable gate array (FPGA) from the Altera Cyclone II device family, delivering 33,216 logic elements, 484 maximum user I/O pins, and 1.1 Mbit of on-chip embedded memory in a 484-ball fine-pitch BGA (FBGA-484) package. Built on a 1.2 V CMOS process, it operates across an industrial temperature range of -40C to +85C and supports a maximum internal clock frequency of approximately 402.5 MHz. The device integrates up to 150 embedded 18x18 multipliers for DSP operations and high-speed external memory interfaces for DDR/DDR2 SDRAM and QDRII SRAM. An FPGA (field-programmable gate array) is a reconfigurable semiconductor device whose logic function is defined by a customer-supplied bitstream rather than hard-wired during fabrication. The Cyclone II family sits within the broader programmable logic taxonomy: FPGA -> programmable logic -> logic IC -> integrated circuit -> semiconductor. Unlike microcontrollers which execute sequential firmware, FPGAs implement parallel hardware logic that can be updated in the field, making them ideal for prototyping, low-volume production, and applications where hardware parallelism outperforms software. The EP2C35 specifically targets the mid-density segment with 33K logic elements, balancing cost per logic element against capability. Key features of the EP2C35F484I6N include 2,100 Logic Array Blocks (LABs) organized in 33,216 logic elements (LEs), 483,840 bits of embedded RAM (M4K blocks), 4 phase-locked loops (PLLs) for clock management, and 315 embedded 18x18 multipliers in the Cyclone II family (the EP2C35 provides 35 embedded multipliers per Cyclone II datasheet). The device supports multiple I/O standards including LVDS, SSTL, HSTL, PCI, and PCI-X through configurable user I/O banks. Its 1.2 V core voltage with 1.2 V/2.5 V/3.3 V I/O supplies enables mixed-voltage system design. The Cyclone II architecture uses a 4-input look-up table (LUT) based logic element with a dedicated carry chain, distributed M4K memory blocks, and embedded multiplier blocks. This heterogeneous fabric allows efficient implementation of arithmetic DSP pipelines, FIFO buffers, and state-machine control logic without external components. The PLLs provide clock multiplication, division, phase shifting, and duty-cycle correction for interfacing with external memory and high-speed peripherals. Typical applications for the EP2C35F484I6N include industrial motor control, video processing and image filtering, telecommunications line cards, software-defined radio DSP front-ends, and automotive driver-assistance prototypes. Designers choose the EP2C35 when they need a balance of logic density, DSP performance, and BGA packaging for high-pin-count systems. The 484-ball FBGA package supports the maximum user I/O count of the device, enabling wide parallel buses and multiple high-speed serial interfaces simultaneously. When designing with this device, engineers should follow Intel/Altera board layout guidelines for BGA fanout, power-plane decoupling, and PLL analog supply isolation. The Quartus II design suite (now Intel Quartus Prime) provides synthesis, place-and-route, and timing analysis for the Cyclone II family. Because the EP2C35F484I6N is a mature part originally launched circa 2005, engineers should verify current lifecycle status before new design starts. This page synthesizes distributor pricing, drop-in pin-compatible alternatives from the Cyclone II family, and practical board-level design notes not found in the manufacturer datasheet alone. It is intended for engineers evaluating mid-density FPGAs for cost-sensitive parallel-processing designs.
