The Intel (formerly Altera) EP2C20F484C8 is a member of the Cyclone® II family of low-cost FPGAs fabricated on a 90 nm process. The device integrates 18,752 logic elements, 239,616 bits of embedded RAM organized into M4K memory blocks, and 315 user I/Os in a 484-ball FineLine BGA package. Core operating voltage is 1.2 V with support for multiple I/O standards across 8 I/O banks. What is an FPGA? A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be reconfigured by the designer after manufacturing. FPGAs sit between discrete logic and application-specific integrated circuits (ASICs): unlike ASICs they require no fabrication masks, and unlike microcontrollers they implement logic in dedicated parallel hardware rather than sequential firmware. FPGAs are widely used for digital signal processing, glue logic, video/display bridging, and prototype ASIC emulation. Key Cyclone II features include up to 150 embedded 18×18 multipliers, four phase-locked loops (PLLs) for clock management, and support for external memory interfaces including DDR/DDR2 SDRAM and QDRII SRAM. The Cyclone II architecture provides a low-power, cost-optimized platform that was a popular choice in the late-2000s era for consumer, industrial, and communications designs. The 484-FBGA package exposes a high I/O count while maintaining a small PCB footprint suitable for high-density designs. Typical applications include digital video processing pipelines, motor control and industrial automation, telecommunications line cards, test and measurement equipment, and embedded control systems. The combination of embedded multipliers and dedicated memory blocks also makes the EP2C20 well suited for soft-core processor implementations such as Nios II, which Altera provides royalty-free for this family. Designers should consult Altera's Quartus II design software (legacy versions still in use) and the Cyclone II Device Handbook for pin assignments, timing closure, and configuration schemes (AS, PS, JTAG). The EP2C20F484C8 is in production but is positioned as a mature, cost-down device - engineers building new designs should evaluate Cyclone IV or Cyclone V/10 families unless an exact Cyclone II replacement is required for board-level compatibility. This page synthesizes distributor pricing, drop-in package-compatible alternatives, and practical design notes that are not aggregated in a single place on the manufacturer datasheet. Engineers evaluating this part for new designs or maintenance of legacy Cyclone II hardware will find the alternatives and comparison data here particularly useful.

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. The data was last verified on 2026-09-08 from distributor and cross-reference listings, giving engineers a single decision point for legacy Cyclone II designs.

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. It helps engineers make faster sourcing and migration decisions for legacy Cyclone II sockets.

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 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.

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.

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.

The device integrates up to 150 embedded 18 x 18 multipliers, supporting high-performance yet low-cost DSP implementations. A Field Programmable Gate Array (FPGA) is a semiconductor device built around a matrix of configurable logic blocks (CLBs) connected via programmable interconnect. Within the broader hierarchy, FPGAs sit under programmable logic devices (PLDs) and digital ICs, complementing ASICs by offering hardware re-programmability, fast time-to-market, and parallel DSP capability for signal-processing and control-plane workloads. Key features of the EP2C35F484I7N include 33,216 logic elements organized into 2,100 logic array blocks, 35 embedded M9K memory blocks (483,840 RAM bits total), up to 150 18 x 18 hardware multipliers for DSP, and 4 phase-locked loops for clock management.

EP2C35F484I8 - 33,216-Cell, 1.2V Cyclone II FPGA | Intel
Intel EP2C35F484I8 is a Cyclone II field-programmable gate array with 33,216 logic cells, 483,840 bits of embedded memory, 322 user I/Os, and a 1.2 V supply in a 484-ball FBGA package. Verified distributor data identifies the device as a 484-BGA FPGA, while Arrow additionally specifies a 402.58 MHz frequency and tray packaging. The I8 ordering-code data indicates an industrial operating-temperature grade, and DigChip gives an operating range of 0 °C to 85 °C. Exact package dimensions, configuration-memory size, embedded multiplier count, PLL count, speed grade, I/O-bank count, and supported I/O standards are not present in the supplied excerpts and therefore require datasheet verification. A field-programmable gate array is a programmable semiconductor containing configurable logic blocks, routing resources, and specialized functional blocks. Unlike a fixed application-specific integrated circuit, an FPGA can implement changing digital logic, interface protocols, control functions, and signal-processing datapaths through a user-generated configuration. Within programmable logic, the hierarchy is FPGA, programmable logic IC, configurable logic device, and integrated circuit. The Cyclone II family combines high logic capacity with embedded memory resources for cost-sensitive digital systems. The headline capacity of 33,216 logic cells supports substantially larger state machines, parallel datapaths, and multi-interface bridges than smaller programmable devices. Its 483,840 memory bits provide on-chip storage for FIFOs, lookup tables, buffers, and control records. A 322-I/O budget permits connection to numerous external memories, data converters, communications peripherals, and control signals. The 1.2 V core supply and 484-FBGA package are central to power-distribution, signal-integrity, and board-layout decisions. The EP2C35 device architecture is configured after board assembly through an external configuration process; exact supported configuration modes and pins must be obtained from the complete manufacturer datasheet before schematic release. The supplied datasheet excerpt states that the EP2C35 I/O count includes 16 dedicated clock pins that can also be used as data inputs. Clock planning therefore should distinguish package I/O capacity from general-purpose user-I/O requirements rather than treating all 322 pins as identical. Typical applications include industrial automation controllers, communications-interface equipment, test and measurement systems, and digital-video or display controllers. These systems benefit from parallel processing, reconfigurable interfaces, and the device's 33,216-cell capacity, 483,840 embedded memory bits, and 322 I/Os. Designers must still validate timing closure, configuration circuitry, termination, decoupling, and signal integrity against the target speed grade and complete Cyclone II datasheet. The most important procurement concern is that the supplied search identifies this mature Cyclone II device but provides no explicit lifecycle statement. Treat lifecycle status as unknown until confirmed from an official Intel product record. No verified cross-reference result establishes a pin-compatible drop-in replacement, so alternatives are limited rather than padded with functional or cross-package devices. This data synthesis adds verified purchasing links, package-aware replacement analysis, application guidance, and clearly marked datasheet gaps beyond a typical distributor listing. Prices are quoted as of 2026-09-08 from the only supplied unit-price snippet, while stock and lead time remain source-specific.

What is an FPGA? A Field Programmable Gate Array (FPGA) is a programmable logic device whose architecture is built from an array of configurable logic blocks (CLBs), embedded memory blocks, multiplier/DSP blocks, and a programmable interconnect fabric. In the electronic component hierarchy, an FPGA sits between a microcontroller and a custom ASIC: like a microcontroller it is software-configurable and low-NRE, but like an ASIC it can run truly parallel logic at multi-hundred-MHz clock rates. The Cyclone II family targets cost-sensitive high-volume applications such as digital signal processing, video bridging, and custom peripheral interfaces. Key features include 4 embedded PLL blocks for clock synthesis and skew management, 35 embedded 18×18 multipliers for DSP workloads, a 4-Mbit on-chip RAM subsystem, and support for external memory interfaces including DDR/DDR2 SDRAM and QDRII SRAM. The LVDS / LVTTL / SSTL / HSTL I/O bank architecture supports single-ended and differential signalling up to 475 I/O, with per-bank reference voltage support.

Quartus II design software (legacy; current support is via Intel Quartus Prime with Cyclone II device support) is used for synthesis, place-and-route, and timing closure. Typical applications include industrial motor control, video surveillance and image processing, low-cost protocol bridging (PCI to local bus, Ethernet MAC), consumer audio/video processing, and telecom line-card glue logic. The 672-BGA FineLine package provides a 27 x 27 mm footprint with 1.0 mm ball pitch, suitable for multi-layer PCBs using standard BGA assembly processes. When designing with this part, plan a multi-rail power tree (1.2 V core, 2.5 V/3.3 V analog PLLs, I/O bank voltages), respect simultaneous switching output (SSO) limits per bank, and provide decoupling per Cyclone II handbook guidelines. The Cyclone II family is in mature production but has been surpassed by Cyclone IV/V/10 LP for new designs; sourcing risk should be evaluated for long-life programs.

EP2C35F672C8 - Cyclone II FPGA, 33K LEs, 672-BGA | Altera
The Altera EP2C35F672C8 is a member of the Cyclone II family of low-cost, low-power Field-Programmable Gate Arrays (FPGAs), fabricated on a 90 nm process and offered in a 672-pin FineLine BGA package. The device integrates 33,216 logic elements, 483,840 bits of embedded RAM organized as M4K blocks, and 35 embedded 18x18 multipliers, making it well-suited for high-volume digital logic, DSP, and embedded control applications. The 'F' in the part number denotes the 672-ball FineLine BGA, while the 'C8' speed grade indicates a commercial 8 ns pin-to-pin logic delay tier. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that can be rewired by the end user after manufacture. FPGAs sit in the broader category of programmable logic devices (PLDs) and bridge the gap between fixed-function ASICs and software-driven microcontrollers, offering hardware-level parallelism for DSP, protocol bridging, and custom interface designs. Within Altera's (now Intel) portfolio, Cyclone II occupies the low-cost, low-power tier beneath Cyclone III/IV/V and the high-performance Stratix families. Key features of the EP2C35F672C8 include support for up to 475 user I/O pins, four phase-locked loops (PLLs) for clock management, dedicated DDR/DDR2 memory interfaces with integrated data strobe (DQS) pins, and support for multiple I/O standards including LVDS, SSTL, and LVTTL. The 90 nm process delivers a favorable core dynamic-power profile compared with older Cyclone generations, and the 672-BGA package exposes the maximum I/O count for the EP2C35 die. Architecturally, the device is built around LABs (Logic Array Blocks) of 16 LEs each, columns of M4K memory blocks, and DSP blocks for multiply-accumulate operations. Configuration is loaded through the active serial (AS), passive serial (PS), or JTAG interface, and the bitstream is stored in industry-standard EPCS configuration devices. The four PLLs provide frequency synthesis, phase shifting, and clock de-skew for system-level timing closure. Typical applications include industrial motor control, video processing, software-defined radio (SDR) baseband, embedded vision, and low-cost ASIC prototyping. Designers frequently target the EP2C35F672C8 when they need 30K+ LEs with a rich DSP and memory mix at the lowest unit price in the Cyclone II lineup, and where the 672-BGA's high I/O count supports wide external memory buses and multi-standard I/O. When designing with this device, attention must be paid to power distribution across the multiple VCCINT, VCCIO, and PLL supply rails, and to the 672-BGA PCB escape routing - the 1.0 mm pitch demands either microvia or laser-drilled via technology. Designers upgrading to Cyclone III/IV should expect pinout and supply-rail changes, so the EP2C35F672C8 is rarely a drop-in swap for newer families.

EP2C35F672C8ES - Cyclone II FPGA 33K LE, 672-FBGA | Intel/Altera
The Intel (formerly Altera) EP2C35F672C8ES is a member of the Cyclone® II family of low-cost FPGAs fabricated on a 90nm CMOS process, housed in a 672-ball FineLine BGA (FBGA) package. It delivers 33,216 logic elements, 483,840 bits of embedded RAM, and 35 embedded 18x18 multipliers, with up to 475 user I/O pins. The device is pin-compatible with the broader EP2C family, enabling designers to migrate up or down the logic-density range without PCB rework. A Field Programmable Gate Array (FPGA) is a programmable logic device that contains an array of configurable logic blocks (CLBs), interconnect, memory, and hard IP blocks such as PLLs, multipliers, and transceivers. FPGAs sit between general-purpose microcontrollers and ASICs in the system hierarchy: microcontrollers execute software sequentially, ASICs implement fixed logic, while FPGAs offer parallel, hardware-defined functionality that can be reconfigured at any point. Cyclone II specifically targets cost-sensitive, high-volume applications in the FPGA & CPLD product category within the broader Programmable Logic IC family. This part carries the commercial 0°C to 85°C operating range and supports core supply voltages around 1.2V, with PLL and I/O banks powered independently. Key features of the EP2C35F672C8ES include support for LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards across 4 I/O banks, four general-purpose PLLs, and configuration via JTAG, serial passive, or Altera enhanced configuration devices. The Cyclone II architecture embeds Multiplier blocks that deliver up to 250 MHz DSP performance, along with M4K RAM blocks each supporting dual-port operation and FIFO mode. Dedicated per-pin signal integrity features such as on-chip termination (OCT) simplify board layout. From a design perspective, the EP2C35F672C8ES is commonly used in industrial control, automotive infotainment, video processing, and communications infrastructure. Its 35 embedded 18x18 multipliers make it suitable for moderate-throughput DSP such as FIR filters or video scaling. Designers should note that the 'ES' suffix on the original MPN denotes an engineering sample - production builds typically use the EP2C35F672C8 (without ES). For new designs, confirm commercial-grade availability and lifecycle status. When designing with this FPGA, ensure all four PLL supply pins (VCCA, VCCD_PLL) are properly decoupled with ferrite beads and bulk capacitance. The 672-ball FBGA requires 26mm x 26mm PCB area and microvia stack-up for reliable assembly. Use the Quartus II design software (latest service pack for legacy device support) for synthesis and place-and-route, and verify timing with the TimeQuest timing analyzer.
