EP4CE40F29I8LN - 39.6K LE Cyclone IV E FPGA, 780-FBGA | Intel

The Intel (formerly Altera) EP4CE40F29I8LN is a Cyclone IV E Field-Programmable Gate Array (FPGA) featuring 39,600 logic elements, 1,161,216 bits of embedded memory, and 532 maximum user I/O, packaged in a 780-ball FineLine BGA (FBGA) and fabricated on a low-power 60 nm process. It operates from a 1.2 V core supply with hot-socketing support and is rated for the industrial temperature range of -40 °C to 100 °C with speed grade 8. A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and dedicated hardware such as block RAM, DSP blocks, PLLs, and high-speed transceivers. FPGAs sit in the programmable-logic tier of the broader digital IC hierarchy between ASICs (higher NRE, higher performance) and microcontrollers (lower performance, software-driven), enabling hardware-level parallelism, deterministic latency, and field upgradability for applications where general-purpose processors cannot meet throughput or timing requirements. Key features of the EP4CE40F29I8LN include 4 input look-up tables (LUTs), 113 18x18 hardware multipliers, four general-purpose PLLs, 116 Kbits of distributed RAM, and 532 maximum user I/O pins routed through eight I/O banks supporting LVDS, LVCMOS, SSTL, and HSTL I/O standards. The device also integrates dedicated configuration logic supporting passive serial (PS), active serial (AS), and JTAG configuration modes. The Cyclone IV E architecture balances logic density, embedded memory, and DSP capability with low static and dynamic power, achieved through the 60 nm process and per-bank I/O voltage scaling. The 780-FBGA package exposes the maximum I/O count of the EP4CE40 device family, enabling high-bandwidth parallel interfaces to external memory and high-speed peripherals. Typical applications include industrial motor control and drive systems, factory automation controllers, video processing and display pipelines, telecommunications line cards, and military/aerospace avionics subsystems. The wide industrial temperature range and robust logic capacity make the EP4CE40F29I8LN well-suited to designs that require deterministic real-time performance with hardware parallelism. When designing with this device, plan I/O bank assignments carefully to avoid VCCIO bank supply conflicts, and follow the Quartus II / Quartus Prime power-up and configuration sequencing recommendations. Because the 780-FBGA package is large and BGA-routed, PCB stack-up, microvia design, and thermal management must be addressed in the early schematic/layout phase.

Typical applications for the EP4CE55F23A7N span industrial motor control, video bridging and image processing, automotive driver-assistance and infotainment pre-processing (AEC-Q100 grade), low-cost ASIC prototyping, and communications line-card glue logic. Designers choose this part when they need mid-range logic capacity (around 50K LEs), generous DSP throughput, and a wide I/O count in a proven, mature, low-power node. When designing with this device, pay attention to power-rail sequencing: VCCINT (1.2 V core) must ramp before or simultaneously with VCCA (2.5 V analog PLL supply), and VCCIO banks can be powered independently. Use the Quartus II / Quartus Prime design suite (Cyclone IV E device support) for synthesis, place-and-route, and timing closure - older Quartus II 13.0sp1 / 13.1 is the last officially supported version.

The Intel (formerly Altera) EP4CE55F23C8 is a Cyclone IV E field-programmable gate array (FPGA) with 55,856 logic elements, 2,340 Kbits of embedded M9K SRAM, 154 embedded 18x18 multipliers, and 4 PLLs, fabricated on a 60 nm low-power process and housed in a 484-ball FineLine BGA package. It integrates 324 user I/O pins, supports a 1.2 V core supply, and is built for high-volume, cost-sensitive applications that need a balance of logic density, on-chip memory, and DSP capability. An FPGA (Field-Programmable Gate Array) is a semiconductor device built from a matrix of configurable logic blocks (CLBs) connected via programmable interconnect. FPGAs sit above microcontrollers and fixed-function ASICs in the design hierarchy: unlike an MCU they execute logic in dedicated hardware rather than software, and unlike an ASIC they are re-programmable after manufacture. The Cyclone IV E family specifically targets low-power, low-cost, transceiver-free applications that still require substantial parallel processing and DSP throughput. Key features include 55,856 logic elements, 2,340 Kbits of embedded memory arranged in M9K blocks, 154 dedicated 18x18 hardware multipliers for DSP, 4 phase-locked loops (PLLs) for clock management, and 324 maximum user I/O pins. The 1.2 V core voltage and 60 nm process enable low static power consumption, while the 484-ball FineLine BGA package exposes the full I/O count plus dedicated configuration, clock, and JTAG pins. Architecturally, EP4CE55F23C8 uses SRAM-based configuration cells organized into Logic Array Blocks (LABs), with each LAB containing 16 logic elements. Embedded M9K memory blocks can be configured as RAM, ROM, shift registers, or FIFO buffers, while the 18x18 multipliers can be paired to form 36x36 signed multipliers. The four PLLs support clock multiplication, division, phase shifting, and zero-delay buffering, enabling complex multi-clock domain designs. Typical applications include industrial motor control, video processing pipelines, automotive infotainment pre-production, prototyping for ASIC designs, test and measurement equipment, and embedded DSP subsystems. The combination of low unit cost, integrated memory, and hardware multipliers makes EP4CE55F23C8 well suited for parallel processing tasks that would otherwise require a DSP or microcontroller plus external logic. When designing with this part, ensure the JTAG chain is properly terminated and that configuration is sourced from a supported mode (AS, PS, JTAG, or fast passive parallel). The 484-FBGA package requires careful PCB layout with controlled-impedance traces for high-speed differential pairs, and thermal management must account for the device's worst-case power dissipation under sustained switching activity.

EP4CE55F23C8L - Cyclone IV E FPGA, 55K LEs, 484-FBGA | Intel

The Intel EP4CE55F23C8L is a Cyclone IV E field-programmable gate array (FPGA) built on a low-power 60 nm process, integrating 55,856 logic elements, 2,396,160 bits of embedded memory, and 324 general-purpose I/Os into a 484-ball fine-pitch BGA (FBGA) package with 1.2 V core operation. The "L" suffix designates an industrial-grade temperature range, while the "C8" speed grade places it in the mid-speed tier of the Cyclone IV E family, balancing logic throughput against static and dynamic power consumption. A field-programmable gate array (FPGA) is a class of programmable logic device that lets designers implement arbitrary digital logic through a sea of configurable logic blocks (CLBs), routing switches, and dedicated hard IP such as multipliers and memory blocks. Within the broader taxonomy, FPGAs sit between application-specific integrated circuits (ASICs) (fixed function, high NRE) and microcontrollers (software-defined, lower throughput). The Cyclone IV E family specifically targets cost-sensitive, high-volume, low-power applications that need moderate logic density and on-chip memory. Key features of the EP4CE55F23C8L include 55,856 logic elements, 2,396,160 bits (approximately 2,340 Kb) of embedded SRAM, 156 hardware 18x18 multipliers for DSP functions, up to 4 PLLs for clock management, and support for external memory interfaces including DDR/DDR2 SDRAM and QDRII+ SRAM. The 484-FBGA package exposes 324 user I/Os, providing ample connectivity for parallel buses, LVDS links, and memory interfaces while keeping board area reasonable for industrial designs. Architecturally, the device uses Altera/Intel's classic 4-input look-up table (LUT-4) logic fabric paired with M9K memory blocks and 18x18 multiplier blocks, all stitched together by a hierarchical routing architecture. Configuration is loaded from a serial or parallel flash device through the standard passive-serial, active-serial, or JTAG paths, and Cyclone IV E devices support both volatile and non-volatile configuration schemes. The 60 nm process and 1.2 V core voltage translate into low static power relative to the prior Cyclone III generation. Typical applications include industrial motor control and machine vision, video processing and broadcast equipment, automotive infotainment prototypes, communications line cards, and embedded control systems. The 55K-LE density is well matched to mid-complexity designs such as multi-channel data acquisition, custom protocol bridging, and image processing pipelines. Because it supports Nios II soft-core processors, the device can also host Linux or bare-metal firmware for system-on-chip designs. When designing with this part, pay close attention to power sequencing on VCCINT (1.2 V) and VCCA (2.5 V) rails: VCCA must not lag VCCINT by more than a few milliseconds, and all I/O banks must be powered before signals are applied. Proper decoupling, a clean reference clock routed with controlled impedance, and adherence to the Quartus II pin connection guidelines are essential for first-pass board bring-up.

It delivers 55,856 logic elements, 2,396,160 bits of embedded memory, and 324 maximum user I/Os in a 484-pin FineLine BGA (FBGA-484) package at 23 x 23 mm with 1.0 mm ball pitch. A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and dedicated hard IP such as multipliers, memory blocks, and transceivers. FPGAs sit within the broader category of programmable logic devices (PLDs), which in turn belong to the digital logic integrated circuit family. Unlike fixed-function ASICs, FPGAs are reconfigured at design time to implement arbitrary digital signal processing, glue logic, control state machines, or even soft-processor subsystems. Key features of the EP4CE55F23C8LN include 156 embedded 18x18 multipliers supporting DSP-intensive designs, 4 PLLs for flexible clock synthesis, and 20 global clock networks. The device operates from a 1.2 V core supply with separate VCCPD and VCCIO banks for mixed-voltage I/O standards such as LVDS, SSTL, and LVCMOS up to 3.3 V. Its hard memory controller and PCIe interface (when available in the family) accelerate common system functions. The "N" suffix confirms lead-free / Pb-free termination consistent with RoHS. Architecturally, Cyclone IV E uses an SRAM-based look-up table (LUT) fabric with 4-input LUTs feeding adjacent registers, and dedicated carry chains for arithmetic. Logic elements are grouped into Logic Array Blocks (LABs); the EP4CE55F23C8LN contains 3,491 LABs. The 484-FBGA package exposes the maximum user-I/O count of the family for this die, ideal for high-pin-count designs. Typical applications include industrial motor control, video processing and display bridging, factory automation controllers, low-cost software-defined radio front-ends, test and measurement instrumentation, and protocol bridging between legacy and modern interfaces (UART/SPI/I2C to Ethernet/PCIe). The combination of DSP blocks and PLLs also suits motor drive encoder interpolation and multi-axis servo control loops. Design consideration: the FBGA-484 package requires careful PCB layout with microvia stack-ups and controlled-impedance traces; ensure reference schematics from the Cyclone IV E handbook are followed for decoupling and bank-power sequencing.

Built on a low-power 60 nm process, it integrates 324 maximum user I/O pins and supports core voltages of 1.2 V with commercial-grade 0 to 85 C junction temperature operation. The F23 package designation indicates the 484-ball 1.0 mm pitch FineLine BGA, while C8 denotes the commercial speed grade 8 and N a lead-free (Pb-free) finish. A Field-Programmable Gate Array (FPGA) is a semiconductor device built around a matrix of configurable logic blocks (CLBs), embedded memory blocks, multipliers, and programmable I/O cells interconnected by a programmable routing fabric. FPGAs belong to the broader class of programmable logic devices (PLDs) and occupy the high-performance tier above CPLDs, enabling hardware-level parallelism for digital signal processing, custom interfaces, and glue-logic consolidation. Cyclone IV E is a low-power, cost-optimized family within Intel's Cyclone IV portfolio, positioned for high-volume, cost-sensitive applications. Key differentiating features include the dedicated 18x18 multipliers supporting DSP applications at up to 200 MHz, embedded memory blocks (M9K) totaling 2,340 Kbits for FIFO and buffer designs, up to four general-purpose PLLs per device for clock synthesis, and support for external memory interfaces including DDR/DDR2 SDRAM and QDRII SRAM. The 324 user I/O pins support LVDS, SSTL, and LVCMOS I/O standards for direct interface to modern memory and high-speed peripherals. The Cyclone IV E architecture combines the 60 nm process with a low-leakage SRAM cell to deliver low static and dynamic power consumption, typically 30 percent lower than the prior Cyclone III generation. This makes the EP4CE55F23C8N well suited for thermally constrained or fanless industrial enclosures where the 31x31 mm FBGA package offers efficient board area utilization with full signal-integrity performance. Typical applications span industrial motor control and factory automation (PLL-driven encoder feedback), video processing and image-pipeline preprocessing, communication protocol bridging (PCI Express endpoint, Ethernet MAC, UART/SPI bridges), test and measurement instrumentation (custom trigger logic, high-speed data acquisition), and display controllers for industrial HMI panels. The 55K LE capacity also supports DSP co-processing for audio codecs and software-defined radio front-ends. When designing with this device, plan FPGA I/O bank voltage assignment carefully; the EP4CE55F23C8N supports up to eight I/O banks each requiring independent VCCIO rails. For DDR2 interfaces, observe the 1.8 V VCCIO constraint and place decoupling capacitors per the Cyclone IV Device Handbook recommendations. Quartus Prime design software is the primary development toolchain.

EP4CE55F23C8N - Cyclone IV E FPGA, 55K LEs, 484-BGA | Intel

The Intel (formerly Altera) Cyclone IV EP4CE55F23C8N is a low-cost, low-power FPGA built on a 60 nm process, integrating 55,856 logic elements (LEs) and 2,396,160 bits of embedded memory into a 484-ball FineLine BGA package. The device operates from a 1.2 V core supply and offers enhanced 8B/10B-capable transceivers up to 3.125 Gbps in some Cyclone IV GX variants; the EP4CE55F23C8N is the non-transceiver Cyclone IV E member with 343 user I/O and 4 PLLs. Speed grade C8 indicates a commercial temperature range (0 °C to 85 °C) and the F23 package is a 484-pin FineLine BGA (23 mm × 23 mm body, 1.0 mm pitch). A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs) connected via programmable interconnect, allowing designers to implement arbitrary digital logic, signal-processing pipelines, and soft processor cores after PCB fabrication. FPGAs sit in the broader category of programmable logic devices (PLDs), between fixed-function ASICs and software-defined microcontrollers; their value lies in rapid prototyping, low NRE cost, and parallel hardware acceleration. Key features of the EP4CE55F23C8N include 55,856 LEs, 2,396,160 bits of RAM (312 Kbytes M9K blocks), 156 embedded 18 × 18 multipliers, four general-purpose PLLs, 343 maximum user I/O pins, and support for external memory interfaces including DDR/DDR2/DDR3, QDR II, and RLDRAM II. The device also offers 1.2 V LVCMOS/LVTTL/LVDS I/O standards with on-chip termination (OCT). Architecturally, the Cyclone IV E family delivers up to 50% lower static power than the previous Cyclone III generation through a low-k dielectric process and selectable logic-array speed versus power trade-offs, while maintaining the same Quartus II design-flow compatibility. The ALM (Adaptive Logic Module) at 8 inputs allows efficient mapping of arithmetic, multiplexer, and register-rich designs, and the variable-precision DSP blocks accelerate finite-impulse-response (FIR) and FFT kernels. Typical applications for the EP4CE55F23C8N include industrial motor-control and machine-vision front-ends, video-bridge and display controllers (HDMI/VGA/LVDS bridging), communications line cards using soft SERDES and protocol bridging, and educational/hobbyist designs where cost, low static power, and Quartus tool maturity matter more than transceiver count. Designers should note that the EP4CE55F23C8N requires 1.2 V core, 2.5 V analog PLL, and bank-specific I/O supplies; the 1.0 mm-pitch BGA demands 4- or 6-layer PCBs with microvia-in-pad stackups for escape routing. Decoupling must follow the Quartus II power-supply decoupling guidelines with 0.1 µF, 0.01 µF, and bulk capacitors distributed across each supply rail. This page synthesizes distributor pricing tiers, drop-in FPGA alternatives from the same Cyclone IV E family, and practical Quartus design-flow guidance not consolidated in the manufacturer datasheet.

The Intel (formerly Altera) EP4CE55F23C9L is a low-power, low-cost Cyclone IV E FPGA delivering 55,856 logic elements, 2,396,160 bits of embedded memory, and 324 user I/Os in a 484-ball FineLine BGA (FBGA) package with -40C to +85C industrial temperature grade. The 'C9' speed grade is the fastest Cyclone IV E commercial/industrial grade, while the 'L' suffix denotes the lower-leakage variant. A Field Programmable Gate Array (FPGA) is a programmable semiconductor whose logic fabric, routing, and I/O cells can be configured by the customer after manufacture. FPGAs sit at the top of the digital-logic hierarchy between standard microcontrollers (fixed-function, software-driven) and application-specific integrated circuits (ASICs, fixed-function, hardware-only). Cyclone IV E FPGAs in particular are SRAM-based devices that must be configured from an external flash on every power-up, which makes them ideal for design iteration, prototyping, and low-to-medium-volume production runs. Key features include 55,856 logic elements, 156 embedded 18x18 multipliers (for DSP), 4 PLLs, 2.5 Mb of embedded SRAM, and 324 general-purpose I/Os that support LVDS, SSTL, LVCMOS, and PCI/PCI-X interfaces. The device supports up to 200 MHz of system performance and integrates a hard memory controller for DDR/DDR2/DDR3 SDRAM, QDR II SRAM, and RLDRAM II. Hard PCIe hard IP blocks are not present on Cyclone IV E (those are Cyclone IV GX), but soft PCIe cores can be implemented in the fabric. Typical applications include industrial motor control, video processing pipelines, telecom bridging, low-cost ASIC prototyping, and embedded vision. The combination of embedded multipliers, large memory, and abundant I/O makes EP4CE55F23C9L a strong fit for parallel DSP workloads such as FIR filtering, FFT engines, and image preprocessing where a microcontroller's sequential execution model becomes a bottleneck. Design consideration: the 'L' (low-leakage) variant reduces static current versus the standard core but at the cost of slightly slower timing closure. Ensure your Quartus Prime timing analysis reflects the chosen speed grade, and budget sufficient decoupling capacitance near the BGA power balls to meet the device's dynamic current demand.

The device runs from a 1.2 V core, is built on a 60 nm process, and uses a lead-free (N) terminal finish according to Intel/Altera ordering data. A field-programmable gate array (FPGA) is a semiconductor device containing reprogrammable logic fabric and programmable routing. Designers configure the logic elements with HDL to implement parallel custom hardware rather than a fixed instruction-set processor. In the broader taxonomy, an FPGA belongs to programmable logic -> FPGA/CPLD -> integrated circuit, and Cyclone IV is a low-cost, low-power FPGA family optimized for high-volume applications. Key features include 55,856 logic elements, organized as 3,491 LAB/CLB blocks; 2,396,160 embedded RAM bits; and 324 general-purpose user I/O. The 60 nm low-power process and 1.2 V core reduce static and dynamic power versus earlier Cyclone families. The speed-grade designator and commercial temperature rating make this part a middle-cost configuration suitable for controlled-environment equipment. The EP4CE55F23 is part of the Cyclone IV E device table that shares the same 484-ball FBGA footprint across EP4CE55 package variants. The fabric uses logic array blocks, each containing sixteen logic elements, and third-party specification data lists 3,491 CLBs. It includes block RAM for data buffering, external memory interfaces, LVDS I/O support, and clock networks. The absence of hard transceivers means high-speed serial links need external PHY/transceiver devices or a different FPGA family with hardened SerDes. Typical applications include industrial motor control, software-defined radio digital front-ends, video and image processing, medical imaging front-ends, test and measurement instrumentation, and IoT edge gateways. With 324 I/O, this FPGA can connect to many ADCs, DACs, memory devices, and system buses while keeping parallel processing in hardware. When designing the 1.2 V power delivery, provide separate low-impedance rails for core and I/O and place decoupling capacitors close to the BGA balls. Because FBGA-484 uses 1 mm pitch, a four-layer PCB with via fanout under the package is recommended; use simulation or a reference design for pin assignments. Ensure configuration device and clock termination are planned before layout.

The verified source data identifies the package as 484-BGA and also describes a 1 mm ball pitch. It is an FPGA IC intended for configurable digital logic, interface bridging, control processing, and high-density embedded applications. A field-programmable gate array is a semiconductor device containing programmable logic blocks, routing resources, and configurable I/O. Engineers configure the FPGA after board assembly to implement digital functions without manufacturing a custom ASIC. Within the semiconductor hierarchy, an FPGA belongs to programmable logic and is used where parallel processing, fast development, field updates, or interface flexibility justify its configuration complexity. The headline density is 55,856 cells, with 3,491 configurable logic blocks and 324 I/O pins. The product listings also identify 2,396,160 embedded memory bits and a 472.5 MHz frequency. These figures place the device in a useful middle-density class for control planes, communication interfaces, test equipment, image processing, and custom accelerators. The high pin count supports multiple parallel external interfaces within one package. The part is associated with a 60 nm Cyclone IV E architecture according to the provided comparison result for another Cyclone IV E device. The I7 ordering suffix in the verified MPN denotes the identified industrial-grade ordering variant, but exact electrical limits should be confirmed from the manufacturer ordering information.

The 324 I/O count is especially useful when the design must connect several sensors, converters, memory devices, or communications ports. Designers should allocate power, decoupling, clock distribution, configuration storage, and signal-integrity resources before routing. BGA assembly requires controlled fabrication, and every high-speed interface must be evaluated for impedance, crosstalk, and return-path continuity. Designers should also verify the exact supported transceiver, memory-interface, voltage, temperature, and speed-grade limits in the manufacturer documentation rather than infer them from family-level descriptions. This page combines the exact distributor and manufacturer values supplied for EP4CE55F23I7 with structured package mapping, practical integration guidance, and comparison data.

EP4CE55F23I8LN - 55K FPGA, 484-BGA | Altera | Embedded Logic

Altera EP4CE55F23I8LN is a Cyclone IV E field-programmable gate array with 55,856 logic elements, 2,396,160 bits of embedded memory, and 324 maximum user I/O pins. The device is fabricated using a 60 nm process and is supplied in a 484-ball plastic/epoxy BGA package identified as F23/484-BGA. The verified ordering-code details identify an industrial temperature-grade device, while exact supported I/O standards, logic-element count nomenclature, and configuration features should be confirmed in the current manufacturer ordering information. A field-programmable gate array is a semiconductor device containing programmable logic blocks, programmable interconnects, and configurable I/O cells. Unlike a fixed-function application-specific integrated circuit, an FPGA can be configured after manufacturing to implement combinational logic, sequential state machines, interfaces, digital signal processing, and bus controllers. Within the semiconductor hierarchy, it belongs to programmable logic, then digital logic, then integrated circuits. Cyclone IV E devices are positioned as low-cost, low-power FPGAs for high-volume and cost-sensitive systems. The headline capacity of EP4CE55F23I8LN includes 55,856 logic elements, 2,396,160 bits of embedded memory, and 324 maximum user I/O pins. The 60 nm process and 1.2 V supply value are reported in the supplied specification data. The 484-BGA package provides a high-density surface-mount interface for complex designs, but its fine-pitch ball array requires controlled PCB fabrication, assembly, inspection, and power-delivery design. The MPN suffix I8 indicates the industrial ordering variant, although complete electrical and environmental limits are not included in the provided snippets. Cyclone IV E architecture is suitable for designs requiring flexible logic, embedded memory blocks, configurable I/O, and hardware parallelism. The device can implement custom bridges, control logic, test fixtures, and low-to-moderate throughput signal processing without requiring a mask revision. The supplied data does not expose operating frequency, transceiver count, block RAM organization, phase-locked-loop count, or exact I/O bank assignments; those values are marked as needed elsewhere rather than inferred from the family name. Typical applications include industrial control and automation, communications infrastructure, video or image-interface bridging, test and measurement equipment, and custom embedded controllers. Its 55,856 logic elements provide capacity for parallel datapaths and multiple peripheral controllers, while 324 maximum user I/O pins support wide external interfaces. Designers must partition logic carefully, verify memory and timing resources, and confirm that the selected package, ball map, configuration interface, and I/O voltage requirements match the PCB. A primary design trade-off is density versus verification effort. Increasing FPGA utilization can improve integration, but reduces timing margin, routing freedom, power headroom, and design headroom. Review the manufacturer documentation, Intel/Altera device-support resources, configuration schematic, and PCB escape routing before release to fabrication. The exact package drawing and full pinout should be taken from the manufacturer data because the provided web data confirms 484 balls but does not provide a reliable per-ball table. This page combines verified MPN capacity, package, process, memory, I/O, stock, and datasheet information with application guidance, selection constraints, and a drop-in-alternative review. It distinguishes the 484-BGA EP4CE55F23I8LN from parts with different packages, densities, temperature grades, or speed grades that cannot safely be treated as direct replacements.

EP4CE55F29C6

EP4CE55F29C6 - Cyclone IV E FPGA, 55K LEs, 780-BGA | Intel

The Intel (formerly Altera) EP4CE55F29C6 is a member of the Cyclone IV E family of low-cost, low-power FPGAs fabricated on a 60 nm process. It integrates 55,856 logic elements, 239,6160 bits of embedded memory (234 Kb), and 374 user I/O pins into a 780-ball FineLine BGA package. Core logic operates from a 1.2 V supply with PLL and I/O banks fed from separate rails, supporting commercial temperature grade operation. A Field-Programmable Gate Array (FPGA) is a semiconductor device containing configurable logic blocks (CLBs), routing interconnects, and I/O cells that designers program after manufacture to implement custom digital circuits. FPGAs occupy a unique position in the silicon hierarchy - more flexible than an ASIC or microcontroller, more deterministic than a software-defined CPU. The Cyclone IV E family sits between low-density CPLDs and high-end Stratix FPGAs, targeting cost-sensitive applications such as industrial control, video bridging, motor control, and I/O expansion. Key features of the EP4CE55F29C6 include 4 phase-locked loops (PLLs) for clock synthesis, 156 embedded 18x18 multipliers for DSP and signal processing, support for external memory interfaces including DDR/DDR2 SDRAM and QDR II SRAM, and dedicated LVDS pairs on every I/O bank. Configuration is supported through JTAG, Active Serial (AS), Active Parallel (AP), and Passive Serial (PS) modes, with optional AES-128 bitstream encryption on security-sensitive builds. The Cyclone IV E architecture combines an FPGA fabric with hard IP blocks such as memory controllers, multipliers, and PLLs. Compared with the previous Cyclone III generation, Cyclone IV E offers higher logic density, lower static power, and up to 150 MHz performance on internal logic with up to 200 MHz on external memory interfaces. The fabric uses 8-input adaptive logic modules (ALMs) and supports M9K memory blocks with true dual-port capability. Typical applications include industrial machine vision and factory automation controllers, motor drive and encoder interfaces, video format conversion (HDMI/VGA/DisplayPort bridging), telecommunications line cards, USB/Ethernet interface bridges, embedded soft-core processors (NIOS II / RISC-V), and educational/development platforms. The 780-ball FBGA package supports high pin counts required by parallel external memory buses, multiple LVDS channels, and GPIO-heavy designs. When designing with this device, careful attention must be paid to power sequencing, decoupling, and thermal dissipation. The 780-FBGA package has a junction-to-ambient thermal resistance in the range of typical high-density BGA packages, so sufficient PCB copper and airflow are required for high-utilization designs. Quartus II / Quartus Prime development tools are required for synthesis, place-and-route, and timing closure. This page synthesizes distributor pricing, same-family drop-in alternatives, and practical board-level design notes not consolidated on any single manufacturer or distributor page.

What is an FPGA? An FPGA (field-programmable gate array) is a reprogrammable digital IC that combines configurable logic, embedded memory blocks, and DSP slices on a single die. FPGAs sit alongside microcontrollers and ASICs in the digital IC hierarchy, and within the Intel/Altera portfolio the Cyclone IV E series targets cost-sensitive, high-volume, low-power applications with a 60 nm process and logic densities from about 6K to 114K logic elements. Cyclone IV E specifically excludes transceivers, distinguishing it from the Cyclone IV GX family. Key features of the EP4CE55F29C6N include up to 472.5 MHz maximum operating frequency, support for LVDS, LVCMOS, SSTL, and HSTL I/O standards, up to 4 PLLs, and configuration via JTAG, passive serial, or Altera EPCS configuration devices. The device supports both 1.2 V core and 2.5 V/3.3 V I/O banks, with embedded 9 Kbit memory blocks (M9K) configurable as RAM, ROM, or FIFO. Architecturally, the EP4CE55F29C6N is built on a TSMC 60 nm low-power process, with 4 input look-up tables (LUTs) per logic element, dedicated carry chains, and embedded multiplier blocks optimized for DSP workloads. The device includes 4 PLLs and 20 global clock networks, enabling complex clock-domain designs. The 780-BGA package provides ample I/O for high-pin-count applications while maintaining a moderate footprint for the logic density offered. Typical applications include industrial motor control, video processing and image pipelines, communications infrastructure (bridges and protocol converters), test and measurement instrumentation, and embedded computing where parallel processing outperforms microcontrollers. The combination of DSP blocks and embedded RAM also suits software-defined radio (SDR) front-end processing. When designing with the EP4CE55F29C6N, pay close attention to power sequencing - core voltage (1.2 V) must ramp before I/O voltages, and proper decoupling per Altera's Cyclone IV handbook is critical for signal integrity. JTAG chain ordering matters when multiple devices share a configuration bus.

The device integrates 3,491 configurable logic blocks (CLBs), 156 embedded 18x18 multipliers, and 4 phase-locked loops (PLLs), supporting up to 472.5 MHz maximum operating frequency. Core logic operates at 1.2 V with multi-voltage I/O banks supporting 1.2 V to 3.3 V interfacing. A Cyclone IV E FPGA is a programmable logic device that sits in the broader hierarchy of programmable logic -> FPGA -> SRAM-based FPGA -> low-power FPGA family. Cyclone IV E targets cost-sensitive, power-conscious applications by replacing discrete logic, microcontrollers, and ASSPs with a single reprogrammable silicon platform that can implement custom parallel processing pipelines, DSP blocks, and custom peripheral bridges. The 'E' variant emphasizes logic density and DSP capability while keeping static power low for volume production. Key features include 55,856 logic elements, 2,396,160 embedded memory bits (arranged in M9K blocks), 156 embedded multipliers, 4 PLLs, and 20 global clock networks. The device supports up to 374 user I/O pins across multi-voltage I/O banks, with LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards supported. Peripherals include JTAG boundary-scan, configuration via serial/parallel flash, and a dedicated Active Serial (AS) configuration interface. The Cyclone IV E architecture uses a 60 nm process node and a logic-array-block (LAB) structure, with each LAB containing 16 logic elements. Embedded multiplier blocks support DSP applications including FIR filters, FFT engines, and video processing without consuming general-purpose logic. Configuration is stored in SRAM, requiring an external configuration device such as the EPCS or EPCQ series flash. Typical applications include industrial motor control, video processing and image aggregation, software-defined radio (SDR) baseband, test and measurement equipment, automotive driver assistance and infotainment subsystems, and PCI Express endpoint bridges. The combination of high logic density, DSP multipliers, and PLLs makes Cyclone IV E particularly suited to parallel data-path designs where microcontrollers cannot meet throughput requirements. When designing with the EP4CE55F29C7, ensure adequate decoupling on every power rail (VCCINT, VCCA, VCCIO banks) and follow Intel's recommended configuration scheme for the selected configuration device. The 780-FBGA package requires fine-pitch PCB layout with 1 mm ball pitch - a 4-6 layer stack-up with dedicated ground and power planes is recommended to maintain signal integrity at LVDS rates. This page synthesizes distributor pricing across nine channels, lists drop-in same-family variants, and provides PCB layout and configuration guidance not consolidated on the manufacturer datasheet front page.

EP4CE55F29C7N - 55K LE Cyclone IV E FPGA, 780-FBGA | Intel

The Intel (formerly Altera) EP4CE55F29C7N is a Cyclone IV E family Field-Programmable Gate Array (FPGA) delivering 55,856 logic elements, 2,396,160 RAM bits, and 374 user I/Os in a 780-ball FineLine BGA (FBGA) package with 1.0 mm ball pitch. It targets cost-sensitive applications that need more logic density than Cyclone IV E entry-level devices, with 3,491 configurable logic blocks (CLBs) and embedded 18x18 multipliers suitable for DSP and signal-processing pipelines. An FPGA (Field-Programmable Gate Array) is a programmable logic device composed of an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, all of which the designer configures after manufacture using an HDL (Hardware Description Language) such as Verilog or VHDL. FPGAs sit at the same level of the programmable-logic hierarchy as CPLDs (Complex Programmable Logic Devices) but offer vastly greater logic capacity and embedded memory, and they belong to the broader semiconductor family of programmable logic ICs. The Cyclone IV E sub-family is Intel's low-power, low-cost line of SRAM-based FPGAs optimized for volume production in industrial, consumer, and automotive markets. Key features include 2,396,160 bits of embedded SRAM organized as M9K blocks, up to 374 user I/O pins supporting multiple I/O standards (LVDS, LVTTL, LVCMOS, SSTL, HSTL), and up to 4 PLLs (Phase-Locked Loops) for clock management. The device supports Nios II embedded processor soft cores, allowing designers to integrate a 32-bit RISC microcontroller directly into the FPGA fabric. Configuration is via JTAG, Active Serial, or Passive Parallel modes, with built-in decompression and encryption engines protecting design IP. Typical applications include industrial motor control and robotics, video processing and image pipelines, automotive driver-assistance subsystems, communications infrastructure, and consumer electronics that require custom logic, DSP, or high-speed parallel interfaces. The -7 speed grade (C7) places it in the mid-performance tier of the Cyclone IV E family, balancing timing margin against cost for mainstream designs. When designing with this device, ensure PCB layout accommodates the 1.0 mm-pitch FBGA with appropriate microvia stack-up and decoupling strategy. Power estimation with the Intel Quartus Prime Early Power Estimator is strongly recommended before final pin assignment, since core and I/O supply currents vary significantly with logic utilization and toggle rates.
