EP4CE55F29C8 - Cyclone IV E FPGA, 55K LE, 780-BGA | Altera

The Intel (Altera) EP4CE55F29C8 is a Cyclone IV E family field-programmable gate array (FPGA) delivering 55,856 logic elements, 2,396,160 bits of embedded memory, and 374 maximum user I/Os in a 780-ball FineLine BGA package. Built on a low-power 60 nm process, the device targets cost-sensitive, high-volume applications that need mid-range logic density without sacrificing signal integrity or I/O bandwidth. Operating from a 1.2 V core supply with separate 2.5 V/3.0 V/3.3 V I/O banks, the EP4CE55F29C8 is rated for the commercial 0 C to +85 C temperature range and supports in-system programming via JTAG or Active Serial configuration. A Field-Programmable Gate Array (FPGA) is a reconfigurable integrated circuit that lets designers implement custom digital logic, memory blocks, and I/O protocols in silicon after fabrication. FPGAs sit alongside ASICs, microcontrollers, and CPLDs in the broader programmable logic taxonomy, with mid-range devices like the Cyclone IV E family balancing logic density, DSP capability, and unit cost for mainstream designs. Cyclone IV E extends the earlier Cyclone III architecture with higher logic element counts, more embedded multipliers (18x18), and a hardened memory controller, making it well-suited to bridging and control-plane tasks rather than high-end DSP. Key features of the EP4CE55F29C8 include 156 embedded 18x18 multipliers for DSP pipelines, 4 PLLs per device for clock management, and 66 embedded memory blocks (M9K) for efficient on-chip buffering. The FineLine BGA-780 package provides high-density board integration while exposing 8 transceiver-free LVDS-capable I/O lanes. Configuration is supported through JTAG (IEEE 1149.1), Active Serial (AS), and Passive Serial (PS) modes, and Quartus II Web Edition handles synthesis, place-and-route, and bitstream generation at no additional licensing cost. The Cyclone IV E architecture uses 4-input look-up tables (LUTs) feeding a high-performance interconnect, with each logic element combining an LUT, register, and carry chain for arithmetic paths. Logic-array blocks (LABs) cluster 16 logic elements plus local routing, enabling efficient pipelined designs. The 60 nm process and 1.2 V core reduce dynamic power roughly 25% versus Cyclone III, while clock-network gating further cuts quiescent consumption in standby states. Typical applications for the EP4CE55F29C8 include industrial motor control and machine vision front-ends, video bridging (BT.656, BT.1120, DisplayPort), PCIe Gen1 endpoint controllers, and consumer electronics requiring mid-density glue logic. The 780-BGA footprint is a common reference design for industrial vision and factory-automation boards where board space is at a premium but raw I/O count matters. With its large embedded memory, the device is also used as a digital signal front-end in software-defined radio (SDR) and instrumentation. When designing with the EP4CE55F29C8, pay close attention to decoupling strategy on the 1.2 V core (recommend 100 nF plus 10 uF bulk per bank) and to I/O bank voltage grouping to avoid level-shift penalties. The 780-BGA's thermal pad should be soldered to a continuous ground plane for low-impedance return paths and effective heat spreading at high toggle rates.

It integrates 156 embedded 18x18 multipliers and supports DDR/DDR2/QDRII/QDRII+/RLDRAM II external memory interfaces, making it well suited for cost-sensitive digital logic, motor control, video bridging, and industrial Ethernet designs. Background knowledge: A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that can be reconfigured by the customer after manufacture to implement arbitrary digital circuits. The Cyclone IV E family sits in Intel's low-cost, low-power FPGA portfolio, optimized for high-volume applications where designers need DSP blocks, embedded RAM, and SERDES-free general-purpose I/O without the cost of a high-end SoC FPGA. Key differentiating features of the EP4CE55F29C8L include 4 PLLs for clock synthesis, 20 global clock networks, support for LVDS, LVPECL, SSTL, HSTL and other high-speed I/O standards, and a core voltage of 1.2 V with hot-socketing capability. The 'L' suffix designates the lower-power speed grade variant operating in the commercial 0C to 85C junction temperature range, while the 'C8' speed grade places it in the middle of the Cyclone IV E speed bin. Architecturally, the device uses SRAM-based configuration memory that must be loaded from an external flash at power-up, supports JTAG (IEEE 1149.1) boundary-scan, and integrates 4 configuration schemes including AS, PS, JTAG, and FPP. Designers can use the Quartus Prime design software (Lite/Standard/Pro editions) for synthesis, place-and-route, and timing closure. Compared with the smaller EP4CE40 in the same family, the EP4CE55 adds 25% more logic and embedded memory for medium-density designs. Typical applications include industrial machine vision, factory automation controllers, motor drive interfaces, video processing and conversion, software-defined radio baseband, and telecommunications line cards. The 780-ball FBGA gives enough I/O and SERDES-free high-speed differential pairs for bridging between parallel CMOS buses and LVDS links. When designing with the EP4CE55F29C8L, pay close attention to power-rail sequencing (1.2 V core before 2.5 V/3.3 V I/O), use the recommended decoupling scheme from the Pin Connection Guidelines, and verify the IBIS model for signal-integrity simulations on LVDS and DDR traces. This page synthesizes distributor pricing, drop-in alternatives from the same Altera/Intel Cyclone IV family, and practical Quartus Prime design notes not found in the manufacturer datasheet alone.

It is specified for commercial temperature grade (0C to +85C) and supports core operation from a 1.2 V supply. The device integrates 374 maximum user I/Os, 156 embedded 18x18 multipliers, and 4 PLLs, giving engineers a balanced compute-and-IO platform for cost-sensitive applications. What is a Cyclone IV E FPGA? Cyclone IV E is the non-transceiver member of Intel's Cyclone IV family, a low-cost, low-power FPGA line architected for high-volume, power-sensitive applications such as industrial control, video processing, and consumer electronics. As an SRAM-based programmable logic device, it sits in the broader hierarchy of programmable logic (FPGA -> programmable logic -> logic IC -> integrated circuit -> semiconductor), and bridges the gap between fixed-function ASICs and microcontrollers when deterministic parallel performance is required. Key differentiating features of the EP4CE55F29C8LN include 55,856 logic elements (the mid-density option in the family), 2,396,160 bits of embedded RAM for buffering and FIFO storage, 156 hardware 18x18 multipliers that accelerate DSP and video scaling pipelines, and 4 general-purpose PLLs for clock synthesis. The device supports multiple I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and HSTL, enabling direct interfacing with DDR/DDR2 memory and a wide range of peripherals without external translation. Technically, the Cyclone IV E architecture combines Logic Array Blocks (LABs) of 16 Logic Elements each, MLABs (Memory LABs) that double as distributed RAM, and embedded M9K memory blocks. Configuration is loaded via JTAG or Active Serial (AS) modes from EPCS or EPCQ flash, with built-in decompression for compressed bitstreams. The 1.2 V core is paired with on-chip voltage regulators that accept a single 3.3 V or 2.5 V supply, simplifying power-tree design on the PCB. Typical applications include industrial motor and motion control, video bridging and image processing, telecommunications line cards, broadcast equipment, and PCIe endpoint expansion. The 780-ball FBGA package with 1.0 mm ball pitch suits boards where moderate IO count, mid-range logic density, and reliable manufacturability are required simultaneously. When designing with this device, plan power sequencing so the 3.3 V analog supply ramps before the 1.2 V core, and use Intel's PowerPlay early-power estimator (EPE) before final pin assignment to verify thermal envelopes. Pin migration from the C7/C9 speed grades is straightforward, but PCIe hard IP availability should be re-validated in Quartus II 13.1 or later. This page synthesizes distributor pricing, drop-in alternative MPNs sharing the F29 780-FBGA footprint, and practical design guidance that goes beyond the Cyclone IV Device Handbook content.

According to the Cyclone IV Device Handbook, the device operates from a 1.2 V core supply with separate 1.2 V/2.5 V/3.3 V bank I/O supplies and provides 374 maximum user I/O pins. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit built around a matrix of configurable logic blocks (CLBs), programmable interconnect, and dedicated hard IP such as block RAM, DSP blocks, and PLL/IO controllers. Unlike an ASIC, an FPGA's logic function and routing are defined after manufacturing by loading a user bitstream into SRAM configuration cells. FPGAs sit at the top of the programmable logic hierarchy: programmable logic device (PLD) > CPLD > FPGA > SoC FPGA, with Cyclone IV E positioned as Intel's lowest-power, lowest-cost Cyclone generation, optimized for high-volume cost-sensitive designs. Key Cyclone IV E features include up to 15,408 Kbits of embedded memory, hardware DSP blocks for high-throughput arithmetic, eight PLLs per device for flexible clock synthesis, and support for external memory interfaces including DDR, DDR2, and QDRII SRAM. The 8 in the suffix indicates a commercial temperature grade (0 C to +85 C) and speed grade 8, while F29 denotes the FBGA-780 package code. The Cyclone IV E architecture combines a 4-input ALM-based logic fabric with embedded M9K memory blocks and 18x18 hardware multipliers. This balance of fabric and hard IP delivers strong DSP throughput at low static and dynamic power, and allows the same silicon to serve cost-driven control planes and moderate-throughput signal-processing pipelines. Typical applications include industrial motor control and PLCs, video surveillance and image processing front-ends, automotive infotainment and driver-assist prototypes, portable medical instrumentation, and low-cost ASIC prototyping. The wide operating temperature range and proven Quartus Prime II tool support make EP4CE55F29C8N a frequent choice for production designs migrated from larger Cyclone III devices. Designers should be aware that Cyclone IV E is in NRND/EOL status; pin-compatible migration paths include Cyclone IV GX (with transceivers), Cyclone V E (28 nm, lower power), and MAX 10 for non-transceiver cost reduction. Always validate Quartus software support before starting a new design. This page consolidates current distributor pricing, same-family drop-in variants, and design considerations not found in a single datasheet - including a comparison of all FBGA-780 Cyclone IV E density and speed-grade options.

Manufactured on a 60 nm low-k process, this device is specified over the commercial 0°C to 85°C junction temperature range (the trailing 'N' suffix denotes lead-free, Pb-free terminal finish) and operates from a 1.2 V core supply with 2.5 V/3.0 V/3.3 V tolerant I/O banks. An FPGA (Field-Programmable Gate Array) is a programmable logic device that allows engineers to implement arbitrary digital logic using configurable logic blocks (CLBs), routing interconnects, and dedicated silicon such as block RAM, DSP blocks, and PLLs. Within the broader semiconductor taxonomy, an FPGA sits below an ASIC in NRE cost but above a discrete microcontroller in logic density, and the Cyclone IV E family targets cost-sensitive, high-volume applications that previously used ASICs or ASSPs. The EP4CE55 sits in the mid-range of the family between the smaller EP4CE30 and the larger EP4CE75/EP4CE115. Key features include 4 PLLs for clock management, up to 8 user I/O banks with LVDS support, hard memory controllers, and on-chip configuration memory. The 780-FBGA FineLine BGA package supports high I/O count with a small board footprint of approximately 29 mm × 29 mm. The 60 nm process enables typical core power well under 1 W in static and a few watts when fully utilized with moderate toggle rates. The Cyclone IV E architecture is built around a sea-of-LABs (logic array blocks) fabric with 4-input look-up tables, fast carry chains, and adjacent M9K block RAM tiles. Each M9K block provides 9 Kbit of SRAM configurable as true dual-port or single-port RAM, FIFO, or ROM. The 374 18×18 multipliers enable cost-effective DSP functions such as FIR filters and FFT butterflies without burning logic resources, and the 4 PLLs support fractional-N synthesis, dynamic phase shifting, and spread-spectrum clocking. Typical applications include industrial machine vision, motor control, video bridging, USB 3.0 protocol bridging, LED video walls, telecom line cards, and portable instrumentation. The combination of mid-range logic density, generous DSP and memory resources, and low static power makes the EP4CE55 well suited to mid-volume embedded designs that need parallel processing or custom high-speed I/O beyond what microcontrollers can offer. When designing with this device, allocate sufficient decoupling on every VCCINT, VCCA, and VCCD_PLL rail. Use at least one 100 µF bulk cap per PCB plus 0.1 µF and 0.01 µF ceramics close to every ball, and follow the IBIS model for SI simulations on LVDS and DDR2/DDR3 edges.

EP4CE55F29I7 - Cyclone IV E FPGA, 55K LEs, 780-BGA | Intel / Altera

The Intel (formerly Altera) EP4CE55F29I7 is a Cyclone IV E field-programmable gate array (FPGA) containing 55,856 logic elements, 2,396,160 bits of embedded memory, and 374 user I/Os, housed in a 780-ball FineLine BGA (FBGA) package with industrial temperature grade (-40C to +100C). It is built on a low-power 60 nm process and targets cost-sensitive, high-volume applications where designers need substantial logic capacity without the cost of a high-end FPGA. What is an FPGA? A Field-Programmable Gate Array is a semiconductor IC whose digital logic function is defined after manufacturing by loading a user-supplied configuration bitstream into on-chip SRAM. Unlike an ASIC (Application-Specific Integrated Circuit), an FPGA can be re-programmed many times, allowing rapid prototyping, in-field upgrades, and hardware acceleration. Within the broader taxonomy, the EP4CE55 belongs to the low-power CPLD/FPGA segment of programmable logic, positioned below high-performance Stratix devices but above MAX series CPLDs. Key features include 55,856 logic elements (LEs), 2,396,160 bits (approximately 2.39 Mbit) of embedded SRAM arranged into M9K blocks, 156 hardware multipliers (18x18), four general-purpose PLLs, and 374 user I/O pins supporting LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards. The device supports configuration via JTAG, active serial (AS), and passive serial (PS) modes. Eight user-controllable clock networks and 20 global clock networks distribute clock signals across the die. Architecturally, Cyclone IV E devices implement an LUT-based fabric (each LE contains a 4-input LUT, a programmable register, and a carry chain) and dedicated memory blocks. The 60 nm process and 1.0 V/1.2 V core voltage yield low static and dynamic power, making this family attractive for power-constrained designs. Per the Cyclone IV Device Family Overview, the I-series temperature grade is rated for industrial ambient operation. Typical applications include industrial motor control and factory automation, video processing and broadcast equipment, automotive driver-assistance subsystems, telecommunications line cards, and PCI Express endpoint bridging. The 780-BGA package provides ample signal pins for high-bandwidth interfaces, while industrial-grade silicon supports deployment in harsh environments. Design consideration: thermal management on a 780-BGA requires attention to PCB stack-up and via-in-pad thermal arrays. Engineers should follow the Altera AN 484 (FPGA Thermal Management) recommendations for footprint and copper-pour design.

The Intel (formerly Altera) EP4CE55F29I8L is a low-power, high-volume Cyclone IV E FPGA featuring 55,856 logic elements, 2,396,160 bits of embedded memory, and 374 user I/Os in a 780-ball FineLine BGA package. Built on a 60nm low-power process, the device targets cost-sensitive, high-volume applications across industrial, automotive, communications, and consumer segments. A Field-Programmable Gate Array (FPGA) is a reconfigurable semiconductor whose logic, memory, and I/O resources are defined by a user-programmed configuration bitstream rather than at the factory. Within the broader programmable-logic taxonomy (FPGA -> programmable logic -> semiconductor), the Cyclone IV E family sits at the entry-level/low-power node, below the higher-density Cyclone IV GX (with transceivers) and the high-end Stratix families. Cyclone IV E devices use a 4-input look-up table (LUT) fabric, dedicated 18x18 multipliers, embedded M9K RAM blocks, and a PLL clock network, offering a balanced logic/memory/DSP mix for mainstream designs. Key differentiating features of the EP4CE55F29I8L include: 55,856 logic elements, 2,396,160 embedded RAM bits organized in 4 M9K/K9K block columns, 156 embedded 18x18 hardware multipliers, 4 general-purpose PLLs, 20 global clock networks, and 374 maximum user I/Os. The 780-FBGA package (F29) supports high pin-count connectivity in a 29x29 mm footprint, while the industrial temperature grade (I8 = -40C to +100C junction, 8 = speed grade 8) suits harsh-environment deployments. Architecturally, the Cyclone IV E family achieves up to 60% lower static power than Cyclone III at comparable performance and integrates configuration options including passive serial, fast passive parallel, active serial, and JTAG. The device operates from a 1.0V/1.2V/2.5V/3.3V multi-rail scheme and supports hot-socketing on user I/O pins. Configuration bitstream is stored in serial NOR flash, EPCS, or downloaded over JTAG using tools such as Intel Quartus Prime Lite Edition (free) or Quartus II Web Edition. Typical applications for the EP4CE55F29I8L span video/image processing pipelines (display controllers, surveillance DVRs), industrial motor control and machine interfaces, motor drive encoder/decoder logic, low-cost software-defined radio (SDR) front-ends, telecom line cards and bridging, and ASIC prototyping. The 55K LE capacity maps well to designs requiring tens of thousands of LUT-equivalents, several megabits of buffering, and moderate DSP throughput without crossing into the Stratix V-class cost band. When designing with the EP4CE55F29I8L, attention to power integrity is essential: a minimum of four 0.1 uF decoupling capacitors must be placed within the BGA power/ground pin grid, and the 1.2V VCCINT must ramp before the 2.5/3.3V VCCAUX/VCCIO rails per the Intel Power-On Reset (POR) sequence. Use the Quartus PowerPlay early-power estimator before RTL freeze to avoid thermal surprises.

An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit whose digital logic functionality is defined after manufacturing via a configuration bitstream. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs), occupying the high-density end above older CPLDs (Complex Programmable Logic Devices). The Cyclone IV E series is a low-cost, low-power family fabricated on a 60 nm process, positioning it between traditional CPLDs and high-end FPGAs for cost-sensitive applications where mid-range logic density is required. Key features include 4 input look-up tables (4-input LUTs) as the basic logic element, embedded 18x18 hardware multipliers for DSP operations, M9K memory blocks distributed throughout the fabric, and up to 8 PLLs for clock management. The device supports LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards and provides 374 user I/O pins. Configuration can be performed through JTAG, AS (Active Serial), PS (Passive Serial), or FPP (Fast Passive Parallel) modes. The Cyclone IV E architecture integrates hard IP blocks including PCIe Gen1 hard IP (in selected variants), external memory interface controllers, and on-chip termination (OCT) calibration, while remaining pin-compatible with Cyclone II designs for migration. The 60 nm process node keeps static and dynamic power low relative to comparable FPGAs, with multiple power modes (normal, fast, slow, standby) that designers can leverage in quiescent states.

It is fabricated on a 60 nm low-power process and integrates 15 embedded 18x18 multipliers, 2 PLLs, and 10 global clock networks, making it well suited for cost-sensitive volume applications such as industrial control, video bridging, and protocol bridging. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs) connected via programmable interconnect. FPGAs sit in the digital logic hierarchy between fixed-function ASICs and software-defined processors: an FPGA offers ASIC-level deterministic parallelism while remaining fully reprogrammable in the field. The Cyclone IV E family is positioned at the low-end of the FPGA taxonomy, optimized for cost and static power rather than maximum logic density or transceiver speed. Key features of the EP4CE6E22A7N include 6,272 logic elements, 270 Kbits of M9K embedded memory (30 M9K blocks), 15 embedded 18x18 multipliers, 4 user I/O banks with support for multiple I/O standards including LVDS, RSDS, mini-LVDS, LVPECL, SSTL, and HSTL, 2 general-purpose PLLs, and 10 global clock networks. The device operates from a 1.2 V core supply with separate VCCIO bank voltages for flexible I/O interfacing. Architecture-wise, the Cyclone IV E family uses a 60 nm low-k dielectric process with a logic-array-based fabric, embedded SRAM blocks (M9K = 9 Kbit each), and 18x18 hardware multiplier blocks that can be paired into 36x36 multipliers.

Configuration is supported through JTAG (IEEE 1149.1), Active Serial (AS), Passive Serial (PS), and Fast Passive Parallel (FPP) modes. Typical applications include industrial Ethernet bridging, motor control encoder interfacing, video format conversion, LED video wall scan drivers, handheld test equipment, and low-cost custom logic replacement for ASICs. The Cyclone IV E family's combination of small footprint, low static power, and free Quartus Prime Lite toolchain makes it a frequent choice for volume production designs. Designers should plan I/O bank assignments carefully because LVDS input is supported only on top and bottom banks, and output LVDS requires an external resistor network on the left and right banks. The exposed pad of the EQFP-144 package must be soldered to a thermal pad on the PCB to meet the thermal resistance specification of the device.

Architecturally, the Cyclone IV E family uses a 60 nm process node with a Look-Up Table (LUT) based logic element, dedicated multiplier blocks, and per-LAB control signals. The device supports hot-socketing, I/O banking with multiple voltage standards (LVTTL, LVCMOS, PCI, SSTL), and 8 Kbits of user flash memory for on-chip non-volatile storage. The exposed thermal pad is electrically tied to the ground plane, providing a low thermal resistance path suitable for convection-cooled industrial enclosures. Typical applications include industrial motor control and drive signal conditioning, consumer video processing bridges, USB/ethernet protocol bridging, low-cost ASIC prototyping, and portable instrumentation front-ends. Designers also use the EP4CE6 in firmware-defined sensor aggregation nodes and LED video wall controllers where deterministic latency is more important than raw throughput. When designing with this device, allocate at least 1 oz copper pour across the exposed pad and stitch it to a low-impedance ground plane; this is the primary heat-dissipation path for LQFP packages. Use the Quartus Prime Lite or Standard edition for synthesis and pin planning, and verify all I/O bank voltage compatibility before PCB layout because mixed-voltage I/O standards share a common VREF within each bank. This page consolidates distributor pricing, drop-in compatible alternatives, and practical design guidance not found in the bare manufacturer datasheet, giving engineers a single reference for sourcing and substituting the EP4CE6E22C8N.

The Intel EP4CE6E22C9LN is a member of the Cyclone® IV E FPGA family, providing 6,272 logic elements, 276,480 bits of embedded memory, and 392 configurable logic blocks (CLBs) in a 144-pin EQFP (22x22mm, 0.5mm pitch) package with exposed thermal pad. Built on a 60nm low-power process, this Cyclone IV E device operates from a 1.2V core supply and offers a maximum user I/O count of 91 with up to 15 embedded 18x18 multipliers for moderate DSP workloads. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose digital logic functionality is defined after manufacturing by the end user via a hardware description language (HDL). FPGAs sit within the broader programmable logic hierarchy (CPLD -> FPGA -> SoC FPGA) and belong to the programmable logic device (PLD) family of integrated circuits. They are used to implement glue logic, custom state machines, parallel DSP, video processing pipelines, and communication protocol bridges where ASSPs cannot meet unique timing or interface requirements. Key features of the EP4CE6E22C9LN include 270 Kbits of distributed RAM, 30 Kbits of M9K block RAM, 4 PLLs, 20 global clock networks, and support for DDR/DDR2/QDRII+ external memory interfaces via soft IP. The device supports LVDS, LVPECL, SSTL, and HSTL I/O standards with hot-socketing capability for in-system programming and field upgrades. An exposed thermal pad on the EQFP-144 package provides a low-resistance thermal path for industrial temperature designs. The Cyclone IV E architecture combines a logic array, embedded memory, embedded multipliers, and per-LAB routing into a fabric where every LAB (logic array block) contains 16 logic elements. This architecture balances logic density, DSP throughput, and power efficiency, making the Cyclone IV E series a popular low-cost alternative to ASICs in volume production from 5K to 1M logic gates. Typical applications include industrial motor control, video surveillance IP cameras, LED video walls, handheld medical instrumentation, factory automation controllers, and embedded vision. Designers use the Quartus® Prime design suite to compile VHDL/Verilog into a bitstream loaded into the on-chip configuration memory via JTAG, AS, or PS modes. When designing with this part, ensure the 1.2V core rail and 2.5V/3.3V I/O rail decoupling network follows Intel's reference board layout, and use the exposed pad with a thermal via array to keep junction temperature within the 100C industrial limit.

EP4CE6E22I7

EP4CE6E22I7 - 6.3K LE Cyclone IV E FPGA, 144-EQFP | Intel

The Intel (formerly Altera) EP4CE6E22I7 is a low-cost, low-power Field Programmable Gate Array from the Cyclone IV E family, built on a 60 nm process and offering 6,272 logic elements (47 Kbits of embedded memory) in a 144-pin EQFP package with exposed thermal pad. It targets high-volume, cost-sensitive applications where the flexibility of programmable logic is required without the expense of high-density FPGAs. A Field Programmable Gate Array (FPGA) is a type of programmable logic device that allows engineers to configure digital logic blocks and interconnects after manufacturing. FPGAs sit in the broader taxonomy of programmable logic -> programmable logic devices -> integrated circuits -> semiconductors. Unlike ASICs (Application-Specific Integrated Circuits), FPGAs can be re-programmed in the field, enabling rapid prototyping, design iteration, and field upgrades. The Cyclone IV E family is positioned in Intel's low-power, cost-optimized portfolio, below the Cyclone V and above the legacy Cyclone III families. Key specifications include 6,272 logic elements, 270 Kbits of embedded RAM (split into M9K blocks), 15 embedded 18 x 18 multipliers, 2 PLLs, 91 user I/O pins, and 8 clock networks. The device operates from a 1.2 V core supply with multi-rail I/O support (LVTTL, LVCMOS, LVDS, SSTL, and HSTL), and total internal SRAM is up to 276,480 bits. The Cyclone IV E family delivers up to 60% lower power than the previous Cyclone III generation at the same performance level. Architecture details: the logic element contains a 4-input LUT that can implement any 4-variable function, combined with a programmable register and a dedicated carry chain for fast arithmetic. The M9K memory blocks support single-port, dual-port, and FIFO modes with true dual-port capability up to 250 MHz. The I/O structure includes dynamic on-chip termination (OCT), slew-rate adjustment, and bus-hold circuitry. Typical applications include industrial control and motor drive, automotive infotainment and driver assistance prototypes, low-cost video bridging and display controllers, machine vision pre-processing, education and university digital logic labs, and consumer electronics glue logic. The 144-pin EQFP package makes hand-prototyping and reflow soldering on 4-layer FR-4 boards straightforward. Design consideration: route the two PLL analog supplies (VCCA_PLL) with a quiet filtered rail and keep the PLL loop filter components close to the pins; for high-speed DDR memory interfaces, use the dedicated DQS delay chains and follow the pin-pair guidelines in the device handbook to avoid setup/hold violations. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found on DigiKey or Mouser product pages - including explicit guidance on EQFP PCB layout and PLL power decoupling.
