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. This page synthesizes current distributor stock levels, exact-spec drop-in alternatives from the Cyclone II family, and practical design notes not found in the bare manufacturer datasheet - intended for engineers evaluating legacy FPGA stock for production or redesign.

EP2C35F672C8N

EP2C35F672C8N - Cyclone II FPGA, 33K LEs, 672-BGA | Altera

The Altera (now Intel) EP2C35F672C8N is a Cyclone II family Field Programmable Gate Array (FPGA) fabricated on a 90 nm low-k process, delivering 33,216 logic elements (LEs), 483,840 total RAM bits, and 475 user I/O pins in a 672-ball FineLine BGA package. It targets cost-sensitive high-volume designs that need substantially more logic capacity than what first-generation Cyclone devices offered, while keeping the silicon cost low through 90 nm process scaling and an optimized LUT-based architecture. A Field Programmable Gate Array (FPGA) is a programmable logic device built from an array of configurable logic blocks (LUTs), programmable routing, and dedicated hard-IP blocks such as block RAM, multipliers, and I/O serializers. FPGAs sit in the broader hierarchy of programmable logic -> programmable logic devices -> digital semiconductor ICs, and are typically used when design flexibility, parallelism, and time-to-market outweigh the unit cost of an ASIC. The Cyclone II family specifically targets the low-cost FPGA segment and is the successor to the original Cyclone series, extending density up to 68,416 LEs and offering up to 1.1 Mbits of embedded memory across the family. The EP2C35F672C8N features 35 embedded 18x18 multipliers for DSP-style operations, four phase-locked loops (PLLs) for clock generation and conditioning, and 33216 logic elements backed by approximately 0.5 Mbit of on-chip RAM. It supports multiple I/O standards including LVTTL, LVCMOS, PCI, SSTL, and LVDS, making it broadly compatible with both legacy parallel buses and high-speed differential interfaces common in industrial and consumer designs. The device operates at a core voltage of 1.2 V with I/O supply rails configurable from 1.5 V to 3.3 V depending on the standard. Architecturally, the EP2C35F672C8N combines a four-input look-up table (LUT) logic fabric with dedicated M4K memory blocks, multiplier blocks, and a row/column interconnect optimized for the 90 nm node. The 672-ball FineLine BGA package exposes 475 usable I/O pins while leaving the remaining balls for power, ground, and configuration. The die is the same silicon used across speed grades, with the speed/grade suffix (C8N) defining timing closure limits rather than functional capability. This means the C7, C8, and C6 variants are typically drop-in alternatives differing only in maximum operating frequency. Typical applications include industrial motor and motion control, video processing pipelines, software-defined radio (SDR) baseband, low-cost ASIC prototyping, and embedded vision front-ends. The large user-I/O count (475) and generous memory bandwidth make it a popular choice for bridging parallel image sensors to processors, glue logic replacement, and education platforms that need to expose many pins for student projects. The wide distribution of the device across octopart-listed suppliers also makes it a familiar reference design for FPGA training boards. When designing with this device, observe the I/O bank grouping rules - each bank shares VCCIO and reference voltage constraints, so split-bus interfaces (e.g., 3.3 V and 1.8 V on the same bus) require careful bank planning. For high-toggle-rate outputs, derate the simultaneous-switching output (SSO) budget per the datasheet I/O chapter to keep ground bounce within spec, and use the Quartus II PowerPlay analyzer to estimate dynamic current before committing to a particular decoupling network.

A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit built around a matrix of configurable logic blocks (CLBs) connected via programmable interconnect. FPGAs occupy a unique position between general-purpose processors (CPUs/MCUs) and application-specific integrated circuits (ASICs): they offer hardware-level parallelism and deterministic timing like ASICs but remain re-programmable, making them ideal for prototyping, low-volume production, and designs requiring late-stage hardware changes. Within the broader taxonomy, the EP2C35 sits in the low-cost, high-volume Cyclone II family, which itself belongs to the programmable logic device (PLD) category of digital ICs. Key differentiating specifications include 4 embedded PLL blocks for clock management, support for multiple I/O standards (LVDS, LVTTL, LVCMOS, SSTL, HSTL, PCI), and a 1.2V core supply (1.15V to 1.25V) with a separate 3.3V I/O supply. The device operates across the industrial temperature range of -40C to +100C (the 'I' suffix) and the speed grade 6 designation places it in the mid-tier performance bucket. The 672-ball BGA package supports up to 322 user I/O pins, making the EP2C35 one of the densest members of the Cyclone II family. The Cyclone II architecture combines a low-k dielectric 90nm process with a logic structure optimized for DSP and consumer applications. Its 18x18 multiplier blocks enable single-cycle multiply-accumulate operations, while the M4K memory blocks can be configured as RAM, ROM, or FIFO with byte enables. This combination makes the EP2C35F672I6N particularly well-suited for parallel DSP pipelines where multiple MAC operations must complete in a single clock cycle. Typical applications include digital video processing, software-defined radio baseband, industrial motor control, low-cost ASIC prototyping, and embedded vision systems. The wide I/O count supports parallel data buses for SDRAM, SRAM, and video ADCs/DACs without external bus multiplexing. When designing with this part, pay close attention to the four PLL configuration constraints and bank-based I/O voltage grouping. The 672-ball BGA requires a 4-layer or better PCB stack-up with controlled-impedance routing and a solid ground pour beneath the device to meet signal-integrity requirements for LVDS interfaces.

The Cyclone II architecture uses a 90nm low-k dielectric CMOS process with a Look-Up Table (LUT) based logic fabric and column-based block RAM, giving designers a balance between density and signal integrity. Internal clock networks span the entire die, and the device supports source-synchronous interfaces up to 250 MHz on LVDS pairs, suitable for parallel ADC/DAC interfacing. Typical applications include industrial motor control and drives, video surveillance and image processing pipelines, automotive infotainment subsystems, telecom line cards requiring bridging logic, and PCI/PCI-Express endpoint implementations. The 484-FBGA package supports the high pin density required for parallel external memory and high-speed LVDS interfaces. When designing with this FPGA, engineers should follow Altera (now Intel) power-estimator and timing-analyzer flows in Quartus II to validate thermal and timing closure. The exposed die paddle requires thermal vias to a copper pour to keep junction temperature within commercial-grade limits.

The Altera (now Intel) EP2C35U484C8N is a Cyclone II family Field-Programmable Gate Array (FPGA) built on a 90 nm CMOS process, delivering 33,216 logic elements, 483,840 bits of embedded memory, and 322 user I/O pins in a 484-ball FineLine BGA package. The 'C8' speed grade corresponds to a commercial temperature range of 0 °C to 85 °C with a logic core voltage of 1.2 V, and the device supports internal operation up to approximately 500 MHz. A Field-Programmable Gate Array (FPGA) is a programmable logic device that combines configurable logic blocks, programmable interconnect, embedded memory blocks, and dedicated multipliers into a single silicon die. Cyclone II sits in the low-cost FPGA segment and is widely used in volume production as glue logic, video/display bridging, motor control, and industrial communications. Architecturally, an FPGA such as the EP2C35 belongs to the broader class of programmable logic devices (PLDs), which themselves sit above ASICs in design flexibility and below microcontrollers in per-unit cost for high-volume applications. Key features of the EP2C35U484C8N include 33,216 logic elements arranged into logic array blocks (LABs), 483,840 bits (roughly 60 Kbytes) of M4K embedded memory, 35 embedded 18 × 18 multipliers, up to 4 PLLs, and 322 general-purpose user I/O pins spread across 8 I/O banks that support a wide range of I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and PCI. Configuration is supported through active serial (AS), passive serial (PS), and JTAG modes. The Cyclone II architecture uses a four-input look-up table (LUT) per logic element, a true dual-port M4K memory block (4 Kbits plus 256 parity bits), dedicated hardware multiplier blocks to accelerate DSP operations, and a flexible multi-clock network. Combined with on-chip PLLs, the EP2C35 offers a balanced resource mix for parallel arithmetic, buffering, and protocol bridging. Typical applications for the EP2C35U484C8N include industrial motor control drives, video capture and display pipelines, telecom interface cards, factory automation controllers, and embedded system prototypes. The 322 user I/Os are sufficient for high-pin-count bridges between microcontrollers, memories, and parallel data buses. When designing with this device, pay close attention to the 1.2 V core supply decoupling scheme, the I/O bank VCCIO planning for mixed-voltage interfacing, and the JTAG chain topology for in-system programming. Always use the latest Altera Quartus II toolchain (or the Cyclone II device support in newer Intel Quartus releases) for synthesis, place-and-route, and timing closure.

EP2C35U484I8 - Cyclone II FPGA, 33K LEs, 484-FBGA | Altera/Intel

The Intel (formerly Altera) EP2C35U484I8 is a Cyclone II family Field-Programmable Gate Array (FPGA) built on a low-power 90-nm process, integrating 33,216 logic elements (LEs) into a 484-pin FineLine Ball-Grid Array (U484 / 484-FBGA, 19x19 mm). The device includes 483,840 bits of embedded RAM organized in M4K blocks, 35 embedded 18x18 hardware multipliers (33216 LEs equivalent shown in DigiKey title is the LE count, while Jotrin describes 2076 LABs / CLBs), and 4 phase-locked loops for clock management, with 322 general-purpose user I/O pins. An FPGA is a reprogrammable integrated circuit whose logic function is defined by user-loaded configuration bitstream rather than fixed mask geometry, allowing rapid prototyping, in-field upgrades, and hardware parallelism unmatched by microcontrollers or DSPs. Cyclone II sits in Altera's low-cost FPGA hierarchy: FPGA → programmable logic → programmable logic device (PLD) → semiconductor, optimized for high-volume cost-sensitive applications such as digital video, communications infrastructure, and industrial control. Cyclone II FPGAs established the cost-optimized FPGA category alongside Xilinx Spartan-3. Key features include 66 (4 per M4K block / RAM block) embedded 18x18 multipliers supporting DSP operations at up to ~250 MHz, support for LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards, hot-socketing capability for live insertion, and a -40C to +100C industrial junction temperature range. The industrial speed grade I8 selects the slowest industrial speed bin, while the U484 package designation identifies a wire-bond FineLine BGA. Configuration can be loaded via passive serial (PS), active serial (AS), or JTAG modes using EPCS serial configuration devices. Typical applications include low-cost video processing pipelines, telecom line-card glue logic, industrial motor-control co-processors, and PCI Express endpoint bridges (using soft IP). The high pin count and large logic capacity suit designs aggregating multiple interfaces such as USB 2.0, Ethernet MAC, DDR/DDR2 memory controllers, and Nios II soft-core embedded processors. When designing, ensure the PCB supports JTAG header (TCK/TMS/TDO/TDI/nCONFIG/nSTATUS) for configuration download, allocate decoupling capacitance per Quartus II power analysis, and verify I/O bank voltage compatibility when mixing LVDS and 3.3V LVCMOS signals.

EP2C35U484I8N - Cyclone II FPGA, 33K LE, 484-FBGA | Intel

The Intel (Altera) EP2C35U484I8N is a member of the Cyclone II family of low-cost FPGAs, fabricated on a 90 nm process and offered in a 484-ball FineLine BGA package. The device integrates 33,216 logic elements, 483,840 bits of embedded RAM, and 322 maximum user I/O pins, providing a high-density programmable fabric for cost-sensitive applications. A field-programmable gate array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs) interconnected via a programmable routing matrix. Cyclone II sits in the low-power, low-cost tier of the FPGA hierarchy between CPLDs (smaller, non-volatile) and high-end FPGAs such as Stratix. It is implemented in 90 nm CMOS technology and supports on-chip memory, embedded multipliers, and PLL-based clock management, making it a true system-on-chip programmable platform rather than a simple glue-logic device. Key features of the EP2C35U484I8N include 35 embedded 18x18 multipliers for DSP-style arithmetic, four PLLs for clock synthesis and skew management, and support for external memory interfaces including DDR/DDR2 SDRAM and QDRII SRAM. Configuration is typically loaded through JTAG or via an external serial/parallel flash, and the part is offered in the -I8N speed/temperature grade (industrial -40C to +100C junction, 8 ns timing). From an architectural perspective, the device is built around LABs (logic array blocks) of 16 LEs each, with a MultiTrack interconnect that minimises routing congestion. The 90 nm process gives a typical core voltage of 1.2 V with separate VCCIO banks for I/O standard flexibility (LVTTL, LVCMOS, SSTL, HSTL, LVDS, PCI). This makes the EP2C35 well suited to bridge legacy 5 V peripherals to modern 1.8 V/2.5 V cores in mixed-voltage systems. Typical applications include industrial motor control, video processing pipelines, telecommunications line cards, prototyping of ASIC designs, and embedded vision. Designers choose the EP2C35U484I8N specifically because it balances logic density, memory bandwidth, and price in a footprint that supports both parallel and serial high-speed interfaces. When designing with this device, pay close attention to the decoupling strategy (a 100 uF bulk plus 0.1 uF and 0.01 uF ceramics per VCC pin group is typical) and to I/O bank voltage planning, because mixing 3.3 V LVCMOS with 1.8 V SSTL on the same bank is not allowed.

EP2C50F484C6 - Cyclone II FPGA, 50K LEs, 484-FBGA | Intel

The Intel EP2C50F484C6 is a Cyclone II family Field-Programmable Gate Array (FPGA) built on a 90 nm CMOS process, delivering 50,528 logic elements and 294 user I/Os in a 484-ball FineLine BGA package. Operating from a 1.2 V core supply, the device supports up to 500 MHz internal operation and integrates 594 Kbit of embedded RAM across 3158 Configurable Logic Blocks (CLBs), giving designers ample headroom for glue-logic, bus-bridging, and DSP pre-processing tasks. The 'C6' speed grade targets commercial-temperature applications and pairs with Altera/Intel's Quartus II design suite for synthesis, place-and-route, and configuration generation. A Field-Programmable Gate Array (FPGA) is a semiconductor device whose logic function is defined by a user-supplied configuration bitstream rather than at the factory. Positioned in the taxonomy as: FPGA -> programmable logic device (PLD) -> integrated circuit -> semiconductor, FPGAs sit alongside microcontrollers, ASICs, and ASSPs in the wider system-on-chip ecosystem but offer the unique advantage of post-silicon hardware re-programmability. The Cyclone II family specifically targets cost-sensitive, high-volume applications where a low unit cost masks the NRE of an ASIC. Key features of the EP2C50F484C6 include 4 phase-locked loops (PLLs) for clock synthesis, dedicated 18-bit x 18-bit hardware multipliers for DSP, 8 Mb of total on-chip memory distributed in M4K blocks, and LVDS/LVTTL/LVCMOS I/O support. It supports configuration via JTAG, Active Serial (AS), Active Parallel (AP), and Passive Serial (PS) modes. The 484-pin FineLine BGA uses a 1.0 mm ball pitch and is footprint-compatible with other Cyclone II F484 devices of differing logic densities (EP2C8, EP2C20, EP2C35, EP2C50, EP2C70). From an architectural standpoint, the Cyclone II LAB (Logic Array Block) is built from 16 Logic Elements arranged in a column, with each LE containing a 4-input LUT, a programmable register, and carry chain logic. The M4K memory blocks (4 Kbit each) double as simple dual-port or single-port RAM, ROM, or shift registers, eliminating the need for external SRAM in many bus-interface designs. Typical applications include industrial motor control and factory automation front-ends, video/image processing pipelines, software-defined radio (SDR) baseband, telecommunications line cards, low-cost digital signal processing, and educational/development platforms. The combination of 50K logic elements, 8 Mb on-chip RAM, and 18-bit hardware multipliers makes it a sweet spot for mid-density control-plane and signal-conditioning designs. When designing with this part, plan your pin assignments against the four PLL-driven global clock networks early to avoid later place-and-route congestion. The C6' speed grade offers a balance of timing margin versus cost; if the timing closure is too tight, step up to the C7 or C8 grade in the same package without any PCB changes.

Built on a 90 nm low-k dielectric process, the device operates from a 1.2 V core supply with 1.5 V/1.8 V/2.5 V/3.3 V multi-voltage I/O support and is rated for commercial temperature operation (0 C to +85 C). The 'C6' speed grade and 'N' lead-free suffix indicate a commercial-grade silicon revision with Pb-free packaging. A Field-Programmable Gate Array (FPGA) is a semiconductor device containing a matrix of programmable logic cells, embedded memory blocks, and programmable routing that engineers can configure after manufacture to implement arbitrary digital logic. FPGAs sit hierarchically between discrete logic ICs (lower density, fixed function) and ASICs (higher volume, fixed mask-set), and they belong to the broader programmable logic device (PLD) family that also includes CPLDs and SPLDs. Cyclone II specifically targets cost-sensitive high-volume applications by combining low-power 90 nm geometry with embedded 18x18 multipliers and M4K RAM blocks, eliminating the need for external multipliers in DSP pipelines. Key features include 50,528 logic elements, 594,432 RAM bits, 129 embedded 18x18 multipliers for DSP workloads, and 4 PLLs for clock management. The device supports LVDS, SSTL, LVTTL, PCI, and LVCMOS I/O standards and offers up to 16 global clock networks. Embedded memory is organized into M4K blocks of 4 Kbits each, configurable as RAM, ROM, or FIFO. The Cyclone II architecture uses a Look-Up Table (LUT)-based logic element combined with a fine-grained routing interconnect, delivering a balance of logic density and predictable timing closure. The 90 nm process node positions this part between the older Cyclone (130 nm) family and the newer Cyclone III (65 nm) family, making the EP2C50 a cost-effective choice when low unit price matters more than absolute lowest power. Typical applications include industrial motor control, video processing, software-defined radio, embedded vision, and prototyping bridges to ASICs. Cyclone II is widely deployed in factory automation, broadcast equipment, and cost-sensitive consumer devices where 50K logic elements and embedded multipliers are sufficient. When designing with the 484-BGA package, allocate an even number of PCB layers for the BGA breakout (typically 6 to 8 layers), keep all decoupling capacitors within 100 mils of their balls, and follow Altera's recommended power sequencing to avoid latch-up. Engineers migrating to a newer device should evaluate Cyclone IV E or Cyclone V for active product longevity, while still using the EP2C50 for new cost-driven designs targeting the legacy Cyclone II silicon revision.

EP2C50F484C7 - Cyclone II FPGA, 50K LE, 484-FBGA | Intel

The Intel (Altera) EP2C50F484C7 is a Cyclone II family Field-Programmable Gate Array (FPGA) delivering 50,528 logic elements, 594,432 bits of embedded RAM, and 294 user I/O pins in a 484-ball FineLine BGA package. The device is fabricated on a 90 nm low-k dielectric process and operates from a 1.2 V core supply with hot-socketing and PCI Express-friendly I/O support, enabling both standalone and bus-resident designs. A Cyclone II FPGA is a SRAM-based programmable logic device that combines lookup-table-based logic blocks with embedded memory, embedded multipliers (DSP blocks), and phase-locked loops on a single die. In the broader system hierarchy, an FPGA sits below application-specific standard products (ASSPs) and above discrete logic gates, offering hardware-level parallelism that microcontrollers and DSPs cannot match. Designers use Cyclone II devices when time-to-market, design flexibility, or parallel signal processing outweigh the per-unit cost advantage of a hard-wired ASIC. Key features of the EP2C50F484C7 include 50,528 logic elements (LEs), 129 M4K RAM blocks (594 Kbit total), 86 embedded 18 x 18 multipliers, four PLLs, and 294 maximum user I/Os. The 484-FBGA package supports a wide range of single-ended I/O standards (LVTTL, LVCMOS, SSTL, HSTL) plus differential standards (LVDS, RSDS, mini-LVDS, LVPECL) on selected pins, giving designers flexibility to bridge legacy and modern ASIC/ASSP interfaces. The Cyclone II architecture uses a four-input LUT as the basic logic element, with a dedicated carry chain for fast arithmetic and a dedicated register per LE. Embedded multipliers are arranged in columns along the device, allowing DSP functions such as FIR filters and FFT butterflies to run at the full 402 MHz internal clock rate. The four PLLs provide clock multiplication, division, phase shifting, and duty-cycle control, which simplifies multi-clock-domain designs and reduces external clock-tree complexity. Typical applications include industrial motor control and factory-automation backplanes, video-processing and image-pipeline front-ends, telecom line cards, low-cost software-defined radio prototyping, and PCI Express endpoint bridging. The 484-FBGA package makes the part suitable for board designs that need the highest I/O count in the Cyclone II family without stepping up to the larger Cyclone III/IV generations. Designers should pay close attention to power-plane decoupling (multiple 0.1 uF and 10 uF caps near each VCC/GAT pair), JTAG chain ordering when multiple Altera/Intel devices share a bus, and configuration-mode selection between AS, PS, and JTAG. The device also requires a configuration flash or download cable for SRAM-based bitstream loading on every power-up.

Built on a low-power 90 nm process, the device targets cost-sensitive, high-volume applications requiring deterministic digital logic and parallel processing at clock rates that typically reach 250 MHz internally. The 'C7' speed grade corresponds to the commercial temperature range (0 °C to +85 °C) with a mid-tier performance bin, and the 'N' suffix indicates lead-free / Pb-free RoHS-compliant packaging. The device integrates four phase-locked loops (PLLs) for clock synthesis, up to 16 global clock networks, hardware multipliers (DSP blocks) for integer arithmetic, and dual-configuration flash memory interfaces for active serial (AS) and JTAG programming. What is an FPGA? A Field-Programmable Gate Array is a reconfigurable semiconductor whose logic blocks and interconnect are defined after manufacture by loading a user-supplied bitstream. FPGAs sit between fixed-function Application-Specific Integrated Circuits (ASICs) and software-driven microcontrollers: they offer hardware-timed parallelism and nanosecond latency like ASICs, while remaining reprogrammable in the field like microcontrollers. Within the broader taxonomy, FPGAs are programmable logic devices (PLDs) alongside CPLDs, and they are commonly used as glue logic, data-path accelerators, or as the main host processor for signal-processing pipelines. The Cyclone II family was Intel/Altera's 2004-vintage low-cost FPGA series and remains widely deployed in industrial, communications, and educational systems today. Key features of the EP2C50F484C7N include 50,528 logic elements (LEs), 594,432 bits of embedded RAM (M4K blocks of 4 Kbit each), 4 PLLs, 16 global clock networks, 250 MHz internal performance, and 294 user I/O pins compatible with multiple I/O standards (LVTTL, LVCMOS, PCI, SSTL, LVDS). The 1.0 V core supply is generated by an on-chip regulator from an external 1.5 V or 3.3 V rail, simplifying power-tree design. JTAG (IEEE 1149.1) boundary-scan support and a passive-serial or active-serial configuration interface allow bitstream loading from EPCS serial flash devices. Typical applications for the EP2C50F484C7N include motor-control and drive front-ends in industrial automation, glue-logic and protocol-bridging in telecom line cards, video-processing and image-pipeline pre-processing, low-cost software-defined radio (SDR) baseband implementations, and educational FPGA development boards. Its combination of moderate logic capacity (~50 KLE), generous block RAM, and 294 user I/Os makes it well suited to bridging parallel bus systems and performing DSP-style FIR/FFT filtering at modest sample rates. When designing with the EP2C50F484C7N, allocate at least eight PCB layers with continuous GND planes beneath the BGA array to maintain signal-integrity for LVDS and DDR-style interfaces. The configuration scheme must be defined in the Quartus II pin-assignment file; leaving MSEL pins floating is a common pitfall that prevents the device from recognizing any configuration source. Finally, observe the I/O bank VCCIO supply constraints - mixing 3.3 V and 1.8 V logic in the same bank will damage the I/O drivers.

The 484-pin FineLine BGA package exposes 8 LVDS pairs and 4 PLLs, allowing high-speed external memory interfaces (DDR/DDR2 SDRAM) and parallel data capture. Internal configuration is volatile SRAM, so an external configuration memory device (such as EPCS4 or EPCS16) is normally required for stand-alone operation. Typical applications include industrial motor control, video format conversion and scaling, software-defined radio front ends, PCI/PCI-X bridge glue logic, and ASIC prototyping for low-to-medium volume products. The wide industrial temperature range and proven 90 nm silicon make the EP2C50F484I8 well-suited to factory-floor and outdoor embedded systems. For new designs, designers should evaluate Intel Cyclone IV E/GX or Cyclone V families, as Cyclone II is a mature node; however the EP2C50F484I8 remains in active service in long-life industrial, military, and aerospace platforms where qualification re-work would be cost-prohibitive. When designing with this device, ensure the configuration scheme (Active Serial, Passive Serial, or JTAG) is selected before PCB layout, and that decoupling follows Altera's recommended capacitor count to suppress core and I/O rail transients during simultaneous-switching events on the large 484-ball BGA. When migrating from the EP2C50F484I8 to a RoHS-compliant alternative, the EP2C50F484I8N is the drop-in lead-free equivalent with identical pinout and electrical characteristics.

EP2C50F484I8N

EP2C50F484I8N - Cyclone II FPGA, 50K LEs, 484-FBGA | Intel / Altera

The Intel (formerly Altera) EP2C50F484I8N is a Cyclone II family Field-Programmable Gate Array (FPGA) delivering 50,528 logic elements, 594,432 RAM bits, and 294 user I/Os in a 484-ball FineLine BGA package, speed grade -8, industrial temperature range. Built on a 1.2V core CMOS process with 90nm technology, the EP2C50F484I8N targets cost-sensitive, high-volume designs where ASIC-class integration is impractical. A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable routing, and embedded memory and multiplier blocks that can be re-programmed in the field to implement arbitrary digital logic. FPGAs sit above microcontrollers and below ASICs in the design hierarchy, offering parallel processing throughput that microcontrollers cannot match while avoiding the NRE cost of ASICs. The Cyclone II family is Intel/Altera's low-cost FPGA line, optimized for consumer, industrial, and communications applications. Key features include 50,528 logic elements organized into 4,508 logic array blocks, 594 Kbits of embedded RAM arranged in M4K blocks, 150 embedded 18x18 multipliers, and 4 phase-locked loops (PLLs) for clock management. The device supports LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards across 8 I/O banks, with per-pin dynamic slew rate and drive strength control. Configuration is supported through passive serial (AS), active serial, and JTAG modes, with on-chip configuration bitstream decryption via the optional AES block. The Cyclone II architecture pairs a fine-grained 4-input LUT-based logic fabric with column-based M4K memory blocks and 18x18 multiplier blocks, enabling DSP-intensive functions such as FIR filters and FFTs without external multipliers. The 90nm process and 1.2V core deliver a favorable performance-per-watt ratio for its class, with typical static power below 200 mW and dynamic power dominated by switching activity on user I/O and clock trees. Typical applications include video processing and display controllers, motor control and industrial automation, software-defined radio baseband, low-cost ASIC prototyping, and PCI/PCI Express bridge designs. The Cyclone II's combination of abundant multipliers and block RAM makes it well-suited to DSP pipelines, while its high I/O count in 484-FBGA suits parallel bus-intensive designs. When designing with this device, plan I/O bank assignments early: each bank has its own VCCIO rail, and LVDS usage requires the dedicated reference-voltage pins. Decoupling must include both bulk capacitors and 0.1uF ceramics placed adjacent to every VCCINT/VCCIO pair, and the configuration mode pins (MSEL) must be hard-wired to select the desired configuration scheme at power-up.

EP2C50F672C6

EP2C50F672C6 - Cyclone II FPGA, 50K LE, 672-FBGA | Intel / Altera

The Intel (formerly Altera) EP2C50F672C6 is a Cyclone II series Field-Programmable Gate Array (FPGA) built on a 90 nm CMOS process, integrating 50,528 logic elements, 3158 Configurable Logic Blocks (CLBs), 594,432 bits of embedded RAM, and 450 maximum user I/O pins in a 672-ball FineLine BGA (FBGA) package. The die is fabricated on TSMC's 90 nm low-k dielectric process and operates from a 1.2 V core supply with 3.3 V/2.5 V/1.8 V/1.5 V LVCMOS/LVTTL I/O standards supported through dedicated I/O banks. Maximum internal clock frequency is rated up to 500 MHz with embedded 18x18 multipliers supporting DSP functions. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing an array of programmable logic blocks, interconnect, and I/O cells that engineers configure after manufacture using a hardware description language. FPGAs sit in the programmable logic hierarchy between ASICs (fully custom, NRE-heavy) and microcontrollers (fixed instruction set). Cyclone II specifically targets cost-sensitive, high-volume applications where the unit price of traditional FPGAs was historically prohibitive - it bridges the gap toward structured ASICs in the cost-performance trade-off curve. Key features of the EP2C50F672C6 include four phase-locked loops (PLLs) for clock synthesis, up to 450 user I/O pins distributed across multiple banks, support for external memory interfaces including DDR, DDR2, and QDRII SRAM, and up to 250 MHz performance on embedded multipliers. The device supports configuration via JTAG, Active Serial (AS), and Passive Serial (PS) modes using commodity EPCS configuration memories, enabling flexible in-system programming. The Cyclone II architecture separates logic, memory, and DSP into dedicated hardware blocks - LABs (Logic Array Blocks) for general logic, M4K memory blocks for variable-width RAM, and embedded multiplier blocks for DSP - avoiding the inefficiency of implementing these functions in soft logic. This hard-IP approach delivers predictable timing closure and competitive performance-per-watt. Typical applications include industrial motor control, video surveillance and image processing, automotive infotainment, telecom line cards, consumer display controllers, and software-defined radio front-ends. The combination of DSP blocks, memory, and flexible I/O makes the EP2C50F672C6 a strong fit for parallel processing tasks where microcontrollers run out of headroom. When designing with this device, pay close attention to decoupling strategy - place 0.1 uF and 10 uF capacitors adjacent to every VCCINT and VCCIO pin pair, and route all PLL analog supplies (VCCA_PLL) through a ferrite bead for noise isolation. Signal integrity on DDR interfaces requires matched-length traces and proper VTT termination; consult the Cyclone II External Memory Interface Handbook for the chosen memory standard. This page synthesizes distributor pricing snapshots from DigiKey/Mouser/Octopart, real drop-in alternatives drawn from the same Cyclone II and Cyclone III device families, and practical PCB-level design notes that complement the manufacturer datasheet's electrical tables.

EP2C50F672C7

EP2C50F672C7 - Cyclone II FPGA, 50K LE, 672-FBGA | Intel / Altera

The Intel / Altera (formerly Altera) EP2C50F672C7 is a member of the Cyclone II family of low-cost, high-volume field-programmable gate arrays (FPGAs), delivering 50,528 logic elements (LEs), 594,432 bits of embedded memory (RAM), and 450 user I/O pins in a 672-ball FineLine BGA package. Manufactured on a 90 nm low-k dielectric CMOS process, this device is offered in the -7 speed grade and the commercial (C) temperature grade (0C to +85C junction), with a core supply voltage of 1.2 V and I/O bank voltages configurable from 1.5 V to 3.3 V via dedicated VCCIO pins. What is a Cyclone II FPGA? It is a SRAM-based programmable logic device from the second-generation Altera Cyclone family, positioned between low-density CPLDs and high-performance FPGAs in the programmable-logic taxonomy (FPGA -> programmable logic -> logic IC -> integrated circuit). Cyclone II introduced 18x18 hardware multipliers, embedded M4K memory blocks, and PLL-based clock management, making it suitable for cost-sensitive DSP, video, and embedded control applications that do not require the serial transceivers of higher-end Stratix devices. Within the Cyclone II family, density scales from EP2C5 (~5K LE) through EP2C70 (~70K LE), with EP2C50 occupying the upper-middle density tier. Key features of the EP2C50F672C7 include 450 user I/O pins (the maximum available on Cyclone II), 4 phase-locked loops (PLLs) for clock synthesis, 86 embedded 18x18 multipliers (150 18x18 multipliers total per device family datasheet) for DSP operations, and 250 M4K memory blocks. The device supports configuration via passive serial (PS), active serial (AS), and JTAG modes using an external configuration device such as the EPCS4 or EPCS16 serial flash. Typical applications for the EP2C50F672C7 span industrial motor control, video processing and display controllers, telecommunications line cards, and embedded computing platforms where a balance of logic density, I/O count, and cost is required. The 672-FBGA FineLine BGA package provides high signal density suitable for multi-channel data acquisition systems. When designing with this device, note that the EP2C50F672C7 is a commercial-grade (C suffix) part in the -7 speed grade; for industrial temperature range (-40C to +100C junction), the EP2C50F672I7 variant should be selected. Configuration requires an external serial configuration device or JTAG download cable, and the Quartus II design software (version 13.0 or earlier for full Cyclone II support) is required for synthesis, place-and-route, and bitstream generation.
