EP4CGX50DF27C6 - 50K LE Cyclone IV GX FPGA, 672-FBGA | Intel

The Intel (formerly Altera) EP4CGX50DF27C6 is a Cyclone IV GX field-programmable gate array (FPGA) delivering 49,888 logic elements, 2,562,048 bits of embedded memory, and 310 user I/O pins, housed in a 672-ball fine-pitch BGA (FBGA-672) package. Built on a low-power 60 nm process, this Cyclone IV GX variant integrates up to eight high-speed transceivers supporting data rates up to 3.125 Gbps, making it one of the lowest-cost FPGAs with multi-gigabit transceiver capability in its class. A field-programmable gate array (FPGA) is a semiconductor IC containing a matrix of configurable logic blocks (CLBs), programmable interconnect, and dedicated hard IP such as memory blocks, DSP blocks, PLLs, and (in GX variants) high-speed serial transceivers. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs) and, in modern systems, are typically compared against microcontrollers for software-driven sequential tasks and against ASICs for high-volume, fixed-function designs; FPGAs win when parallel processing, custom interfaces, or hardware-reconfigurable acceleration are required. Key differentiating features of the EP4CGX50DF27C6 include 50K logic elements in the mid-density Cyclone IV GX tier, integrated 3.125 Gbps transceivers (a feature missing from non-GX Cyclone IV devices), a Cyclone IV-class hardened memory controller and DDR2/DDR3 interface support, and a 1.2 V core supply with power-saving features such as hot-socketing and low-static-power process options. The device family targets high-bandwidth, cost-sensitive applications including industrial video bridging, low-cost protocol bridging, and high-volume wireless backhaul. Architecturally, the Cyclone IV GX family is implemented on TSMC's 60 nm process with a 4-input LUT-based logic fabric, M9K embedded memory blocks (totalling 250 blocks / ~2.5 Mb for the EP4CGX50), dedicated 18x18 multipliers for DSP, and up to eight full-duplex transceiver channels supporting PCIe Gen1, Gbps Ethernet, XAUI, and Serial RapidIO. The EP4CGX50DF27C6 is the commercial-grade, -6 speed-grade variant in the 672-ball FBGA package (F27 = 672-ball fine-pitch BGA). Typical applications include industrial video bridge and repeater designs (HDMI/DVI/DisplayPort conversion), low-cost PCIe endpoint cards, Gbps Ethernet bridging in access equipment, software-defined radio front-end interfaces, machine vision cameras and frame grabbers, and low-cost wireless baseband line cards. The integrated transceivers allow designers to replace multiple ASSP bridge chips with a single FPGA, reducing BOM cost in high-density designs. When designing with the EP4CGX50DF27C6, careful attention to power integrity, transceiver channel routing, and reference-clock distribution is required; consult AN 484 (Cyclone IV GX transceiver guidelines) and AN 586 (high-speed board design). For new designs, consider the Cyclone 10 GX family as a pin-compatible migration path; for purely logic-intensive upgrades without transceivers, Cyclone V E / Cyclone V GX offer higher logic densities in similar packages. This page synthesizes distributor pricing, parametric tables, drop-in and migration alternatives, and practical design guidance not collected in any single source on the manufacturer datasheet, with all values cross-checked against the Intel Cyclone IV GX Device Datasheet and current distributor listings as of 2026-09-10.

EP4CGX50DF27C6N

EP4CGX50DF27C6N - 50K LE Cyclone IV GX FPGA, 672-FBGA | Intel

The Intel (formerly Altera) EP4CGX50DF27C6N is a low-power, high-volume Cyclone IV GX field-programmable gate array (FPGA) with 49,888 logic elements, 2,562,048 bits of embedded memory, and integrated transceivers, housed in a 672-ball FineLine BGA package. The device operates from a 1.2V core supply with separate 2.5V/3.0V/3.3V auxiliary rails and supports the commercial -6 speed grade. The 672-FBGA package exposes 310 user I/O pins and up to eight integrated 3.125 Gbps transceivers, enabling cost-sensitive designs that require high-speed serial connectivity without the cost of a full transceiver-equipped Stratix-class device. A Field-Programmable Gate Array (FPGA) is a reconfigurable integrated circuit whose logic function is defined by user-supplied configuration bitstreams rather than by fixed metal-layer interconnect. Modern FPGAs sit at the top of the programmable-logic taxonomy: programmable logic device (PLD) -> CPLD -> FPGA -> SoC FPGA. They are typically used to implement custom glue logic, high-speed datapaths, parallel DSP, and interface bridging that cannot be served by fixed-function ASICs in low-to-mid volume. The Cyclone IV family is built on a 60 nm low-power process and was designed specifically for cost- and power-constrained applications. Key features of the EP4CGX50DF27C6N include 49,888 logic elements organized into 3,118 logic array blocks (LABs), 2,562,048 bits (~313 Kbytes) of embedded SRAM arranged as M9K blocks, 140 embedded 18x18 multipliers for DSP, four PLLs, and eight integrated 3.125 Gbps transceivers on the GX variant. The device also includes hard PCIe Gen1 IP cores, JTAG and serial configuration interfaces, and supports both passive and active configuration schemes through Altera/Intel EPCS/EPCQ configuration memories. Typical applications include industrial video and image processing, motor control and industrial Ethernet bridging, low-cost PCIe endpoint cards, low-rate serial backplane aggregation, handheld test and measurement equipment, and consumer video capture/display pipelines. The Cyclone IV GX is frequently selected where designers need genuine transceiver capability at a Cyclone-class price and power budget. When designing with the EP4CGX50DF27C6N, pay close attention to power-rail decoupling and to the JTAG chain, because the 672-ball 1.0 mm pitch FBGA requires reflow profiling per JEDEC J-STD-020 and careful escape routing. Quartus II or Intel Quartus Prime is required for synthesis, place-and-route, and bitstream generation. Designers migrating to newer device families should evaluate Cyclone 10 GX as a modern successor with similar logic density and improved transceivers.

Key features include 150 embedded 18x18 multipliers for DSP, support for external memory interfaces (DDR2, DDR3, LPDDR2, QDRII+), and eight full-duplex transceiver channels with integrated physical coding sublayer (PCS) and physical medium attachment (PMA). The device also provides 4 PLLs, 16 global clock networks, and 1.2 V core operation with on-chip voltage regulation. The Cyclone IV GX architecture separates low-power static logic from high-speed serial transceivers, allowing designers to keep dynamic power low for the majority of glue-logic and parallel-processing fabric while still leveraging multi-gigabit serial links. The 60 nm process provides mature, high-yield silicon and predictable timing closure. Typical applications include industrial video bridging, low-cost protocol bridging (PCIe Gen1, Gbps Ethernet, serial RapidIO), motor control and drive feedback, broadcast video processing, and point-to-point radio backhaul. The combination of transceivers and abundant logic makes it well-suited for ASIC prototyping and mid-volume production. Design consideration: PCB layout for the FBGA-672 package requires microvia or via-in-pad technology, controlled-impedance routing for the transceiver channels, and careful power-plane stitching. Decoupling capacitor placement close to the balls is critical for switching-noise suppression.

EP4CGX50DF27I6N

EP4CGX50DF27I6N - Cyclone IV GX FPGA, 49.9K LEs, 672-FBGA | Intel (Altera)

The Altera (now Intel) EP4CGX50DF27I6N is a low-power, high-volume Cyclone IV GX FPGA fabricated on a 60 nm process, integrating 49,888 logic elements into a 672-ball FineLine BGA (FBGA) package with 1.2 V core operation. Built around the Cyclone IV GX architecture, this device combines programmable logic fabric, embedded memory, and 3.125 Gbps transceivers to deliver an optimized cost/performance point for volume-driven serial-interface and parallel-processing designs. A Field-Programmable Gate Array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable interconnects, embedded memory, and hardened functional blocks such as transceivers and PLLs. FPGAs sit at the top of the programmable-logic taxonomy (FPGA -> programmable logic -> digital IC -> semiconductor), enabling engineers to implement custom digital circuits, glue logic, DSP pipelines, and high-speed serial interfaces without committing to a mask-programmed ASIC. Cyclone IV GX further specializes this class by adding 3.125 Gbps multi-gigabit transceivers (MGTs) targeted at protocols such as PCIe Gen1, Gigabit Ethernet, Serial RapidIO, and CPRI at very low static power. Key features of the EP4CGX50DF27I6N include up to 3.125 Gbps transceiver data rate, 8 transceiver channels, 49,888 logic elements, 2,502 Kbits of embedded RAM, 113 embedded 18x18 multipliers, four general-purpose PLLs, and 310 maximum user I/O pins. Transceiver channels support common serial standards including PCIe Gen1 x1/x2, Gigabit Ethernet, Serial RapidIO v1.3, and CPRI, while 3.3 V-tolerant LVTTL/LVCMOS and LVDS I/O accommodate mixed-voltage legacy buses. The device is offered in the industrial temperature grade (-40C to +100C junction), suiting outdoor, factory-floor, and uncontrolled-environment deployments. The Cyclone IV GX architecture pairs the transceiver-rich I/O ring with a fine-grained logic fabric, dedicated 9-Kbit M9K memory blocks, and DSP block multipliers. The static power consumption is typically below 1 W for most designs because the 60 nm low-power (LP) process minimizes leakage. Configuration is supported through Active Serial (AS), Passive Serial (PS), Fast Passive Parallel (FPP), and JTAG modes, with built-in optional 16-bit CRC and 128-bit AES encryption for design security. Typical applications include industrial motor control and drive interfaces, low-cost PCIe endpoint cards, video surveillance and broadcast bridging, software-defined radio front-ends, and factory-automation backplanes. The combination of low cost, integrated transceivers, and small FBGA footprint makes the EP4CGX50 family especially popular in volume production designs. When designing with this part, choose the F27 (672-ball FBGA) variant when higher I/O count and maximum transceiver availability are required; the F23 (484-ball) variant is the lower-pin-count alternative in the same family. Designers should follow Intel/Altera PCB guidelines for FBGA fan-out, signal-integrity simulation of transceiver channels, and reference decoupling on each VCC/VCCIO/VCCPT/VCCA supply rail.

Built on a low-power 60 nm process and operating from a 1.2 V core supply, it integrates up to eight 3.125 Gbps transceivers, making it suited for cost-sensitive serial-link applications. A field-programmable gate array (FPGA) is a semiconductor integrated circuit whose digital logic function is defined by the user after manufacturing. In the wider programmable-logic hierarchy, an FPGA sits above simple CPLDs (Complex Programmable Logic Devices) and below ASICs (Application-Specific Integrated Circuits), bridging the gap between low-density glue logic and high-volume custom silicon. The Cyclone IV GX family adds hardened multi-gigabit transceivers, which historically were reserved for higher-end Stratix devices, while keeping the Cyclone line's low static and dynamic power positioning. Key features include 49,888 logic elements, 2,562,048 bits (approximately 2.44 Mbit) of embedded RAM organized as 9 kbit M9K blocks, an on-chip 4 Kbit per-memory block, 56 embedded 18x18 multipliers, and up to eight 3.125 Gbps multi-gigabit transceivers (MGTs) for protocols such as PCIe Gen1, GigE, SRIO, and CPRI. The device also offers dedicated hard IP for PCI Express Gen1 (x1/x2/x4) and supports JTAG-based configuration via the 1.2 V core supply. The -I7 speed/temperature grade provides an industrial junction range from -40 C to +100 C and a faster speed grade than C7/C8 variants. The architecture combines an SRAM-based 4-input LUT fabric, embedded multipliers, and M9K memory blocks, all tied together by a multi-track interconnect with row and column routing. The hardened PCIe Gen1 controller and multi-gigabit transceivers enable direct interfacing to backplanes, SFP/SFP+ cages, and high-speed ADCs/DACs without requiring external PHY silicon, which simplifies board layout and reduces BOM cost. Typical applications include industrial video surveillance with image-sensor aggregation, low-cost PCIe endpoint cards, multi-protocol serial-link bridges (SRIO, CPRI, OBSAI), motor control and factory automation with FPGA co-processing, and small-form-factor software-defined radio (SDR) front ends. The -I7 industrial grade also makes it acceptable for outdoor or uncontrolled-temperature installations. Designers should note that a 672-ball FBGA requires Xilinx-class PCB fabrication: microvia stack-ups, laser-drilled blind vias, controlled-impedance routing for the 3.125 Gbps lanes, and decoupling density of approximately one 0.1 uF cap per five pins are recommended for signal integrity and power integrity.

The Cyclone IV GX family also integrates 2 PLLs per device quadrant and supports both commercial (0 C to 85 C) and industrial (-40 C to 100 C) operating temperature grades, of which the I7 suffix denotes industrial-grade. Architecturally, the EP4CGX50DF27I7N uses an SRAM-based configuration cell that loads its bitstream from external flash through passive serial, fast passive parallel, or JTAG modes. The 3.125 Gbps transceivers are hard IP blocks operating independently of the programmable fabric, providing deterministic latency and low jitter suitable for serial RapidIO, Gigabit Ethernet, SMPTE SDI, and PCIe Gen1 endpoint designs. Typical applications include industrial motor control, video surveillance and image processing, low-cost wireline bridges, wireless remote radio heads, USB 3.0/2.0 firmware bridges, and PCIe endpoint add-in cards. The combination of transceivers and DSP resources also makes the device suitable for software-defined radio (SDR) front-end signal conditioning and for smart-grid communication gateways. When designing with this part, pay close attention to PCB layout for the 672-ball FBGA: use microvia stack-ups on the top two layers, match BGA escape trace lengths within 25 mil, and provide four decoupling capacitor values (10 uF, 1 uF, 100 nF, 10 nF) per power pin group. The Quartus II / Quartus Prime design toolchain from Intel is required for synthesis, place-and-route, and bitstream generation.

FPGAs belong to the broader category of programmable logic devices (PLDs), which also include CPLDs and older SPLD architectures; they are used when deterministic parallel processing, custom I/O protocols, or hardware acceleration are required. Key features include 3.125 Gbps transceiver channels, 200 embedded 18 x 18 multipliers, 2,562,048 bits of user-accessible RAM distributed across 250 M9K blocks, 4 PLLs, and 20 global clock networks. The device supports PCI Express Gen1 x1/x2/x4 hard IP, external memory interfaces up to DDR2 SDRAM at 200 MHz, and hot-socketing capability. The I8 speed grade and -40 C to +100 C industrial temperature range make it suitable for harsh-environment designs. From an architectural perspective, the EP4CGX50DF27I8N uses an SRAM-based LUT fabric with 8-input fracturable look-up tables, dedicated routing channels, and hard IP blocks for memory controllers and transceivers. The 60 nm process delivers static power low enough for fan-less embedded platforms, while the transceiver PHY provides 8b/10b encoding, word alignment, and rate-matching logic. Typical applications include industrial video broadcast and image processing, telecom line cards with backplane SERDES, low-cost PCIe endpoint cards, motor control, and protocol-bridging mezzanines. The wide temperature range also suits outdoor industrial enclosures and test-and-measurement equipment. When designing with this FPGA, careful power-rail sequencing is required because the 1.2 V core and 2.5 V/3.3 V auxiliary supplies must ramp in a defined order to avoid in-rush latch-up. The transceiver reference clocks demand jitter-cleaner PLLs and well-decoupled analog supplies; isolate the analog and digital ground returns with a single tie-point under the BGA.

The Intel (formerly Altera) EP4CGX75CF23C6N is a Cyclone IV GX field-programmable gate array (FPGA) with 73,920 logic elements, 4,257,792 bits of embedded memory, and 290 user I/Os, packaged in a 484-ball FineLine BGA (FBGA). It is a commercial-temperature-grade variant of the EP4CGX75 family, integrating up to 8 integrated transceivers supporting data rates up to 3.125 Gbps, which makes it a strong fit for cost-sensitive PCIe Gen1/Gen2, Gigabit Ethernet, and Serial RapidIO applications. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and embedded memory and DSP resources. FPGAs sit in the programmable logic family, alongside CPLDs, and are used as glue logic, parallel processors, hardware accelerators, or rapid-prototyping platforms for ASIC designs. Compared with microcontrollers, FPGAs offer deterministic parallelism and far higher I/O throughput; compared with ASICs, FPGAs are reconfigurable in the field and ship with no NRE cost. The Cyclone IV GX family specifically targets low-power, transceiver-rich designs in the 1.0-3.125 Gbps data-rate range. Key features of the EP4CGX75CF23C6N include 73,920 logic elements (LEs), 4,257,792 bits (approximately 4.27 Mbit) of embedded SRAM, 150 embedded 18x18 multipliers, 4 PLLs, and 8 high-speed transceivers. The device is fabricated on a low-power 60 nm process and supports I/O standards including LVDS, LVTTL, LVCMOS, SSTL, HSTL, and PCIe. Designers can configure the FPGA via JTAG, Active Serial (AS), or Passive Serial (PS) configuration modes. The 484-ball FBGA package provides a compact footprint for high-density board designs. Architecturally, the EP4CGX75CF23C6N uses SRAM-based configuration cells, which means the device is volatile and must be reloaded on every power-up from a configuration memory such as the EPCS or EPCQ serial flash. Logic is organized into Logic Array Blocks (LABs) of 16 LEs each, with each LE containing a 4-input LUT, a register, and a carry chain. The transceiver blocks include physical coding sublayer (PCS) and physical medium attachment (PMA) layers hard-wired for protocols including PCIe, GIGE, and Serial RapidIO. Typical applications include low-cost PCIe endpoint cards, industrial vision and image processing, motor control and factory automation, protocol bridging (PCIe-to-Local Bus, GIGE-to-Memory), Software Defined Radio (SDR) baseband, and test & measurement equipment. The combination of built-in transceivers and large logic capacity makes this device particularly popular for embedded prototyping and small-volume production runs. A critical design consideration for the EP4CGX75CF23C6N is power-supply sequencing - the FPGA requires multiple rails (core VCC, VCCPD, VCCA, VCCD_PLL, and transceiver supplies VCCE_GXB and VCCH_GXB) ramped in the correct order to avoid device stress. Decoupling must follow the reference board guideline, with high-frequency decoupling placed as close to each ball as possible. Designers must also allocate sufficient configuration storage (EPCS or EPCQ flash) and select the correct configuration mode via MSEL pins.

EP4CGX75CF23C8 - Cyclone IV GX FPGA, 75K LE, 484-BGA | Intel

The Intel EP4CGX75CF23C8 is a Cyclone IV GX Field Programmable Gate Array (FPGA) from the Cyclone IV GX family, delivering 73,920 logic elements in a 484-ball FineLine BGA package with 290 user I/O pins. Built on a low-power 60 nm process, this device integrates 3.125 Gbps transceivers and a hard PCIe Gen1 IP block for cost-sensitive serial connectivity designs. According to the Cyclone IV Device Handbook, this OPN targets the F23 (484-ball) package with a commercial speed grade 8 rating. A Field Programmable Gate Array (FPGA) is a semiconductor device built around a matrix of configurable logic blocks (CLBs) connected via programmable interconnect. FPGAs belong to the broader category of programmable logic devices (PLDs), which sit between fixed-function ASICs and software-driven processors in the silicon design hierarchy. Cyclone IV GX FPGAs combine general-purpose logic fabric with embedded transceivers, allowing a single chip to implement glue logic, parallel bridges, video processing, and low-speed serial protocols. Key features of the EP4CGX75CF23C8 include 4,620 Configurable Logic Blocks (CLBs), 4,257,792 bits of embedded RAM (approximately 4.05 Mbit when measured in M9K blocks), eight 3.125 Gbps transceivers, two hard PCIe Gen1 IP cores, and 290 general-purpose I/O pins supporting LVDS, SSTL, and LVCMOS standards.

EP4CGX75CF23C8N - 73,920-Cell FPGA | Intel | Embedded

Intel EP4CGX75CF23C8N is a Cyclone IV GX field-programmable gate array with 73,920 logic cells, 290 I/O, and a 1.2 V core supply, housed in a 484-pin fine-pitch ball grid array package. The verified product listing describes 4,257,792 bits of embedded memory and identifies the device as a programmable-logic IC built using 60 nm technology. It belongs to the Cyclone IV GX family, combining general-purpose FPGA fabric with application-oriented programmable resources for embedded processing, communications, and custom digital hardware. A field-programmable gate array is a semiconductor device whose logic functions are configured after manufacturing. In the system hierarchy, an FPGA sits between fixed-function application-specific integrated circuits and software-driven processors: it provides hardware-timed parallel processing while remaining reconfigurable. The Cyclone IV GX family extends this programmable-logic foundation with resources intended for interface, signal-processing, and control functions. This combination allows designers to consolidate glue logic, protocol handling, state machines, and accelerators into one programmable device. The principal verified characteristics are 73,920 cells, 290 user I/O, 4,257,792 memory bits, and a 484-ball FBGA package. The 290-I/O count provides a substantial connection boundary for parallel buses, memory interfaces, control signals, and communications peripherals. The reported 4,257,792-bit embedded-memory capacity supports data buffering, lookup tables, packet storage, and other moderate-size on-chip functions without consuming all logic resources. The 60 nm process designation and 1.2 V supply place the device in a low-voltage, mature FPGA architecture. From an architectural perspective, the programmable fabric can implement concurrent datapaths and control logic directly in hardware. Unlike a processor that executes instructions sequentially, an FPGA can sustain multiple operations in parallel, making it useful for deterministic interface bridging and acceleration. Designers map a design into logic elements, route signals through programmable interconnects, and configure dedicated on-chip memory and I/O behavior. Configuration data therefore determines the final digital function while preserving the flexibility to revise the implementation. Typical applications include industrial automation controllers, communications equipment, real-time signal processing, and custom hardware acceleration. In industrial systems, the device can consolidate machine-control state machines, sensor interfaces, and communication bridges. In communications equipment, its parallel fabric can handle protocol conversion and packet-oriented logic. For signal processing, the same architecture supports high-speed fixed-function datapaths, while the embedded memory can hold coefficients or sample buffers. Design-in work must verify the exact ball map, supported I/O standards, transceiver capabilities, configuration interface, clocking resources, power rails, thermal limits, and speed-grade implications from the manufacturer documentation before release. PCB planning should accommodate all 484 balls, controlled-impedance connections where appropriate, decoupling near supply entry points, and rigorous signal-integrity review. The available verified data does not provide a complete electrical limit table or pin assignment. This page combines the verified ordering, logic, memory, I/O, process, supply, and package information with a conservative engineering review. Because the alternative search did not identify a verified same-footprint cross-brand drop-in replacement, no unverified equivalent is presented. That distinction protects procurement and PCB decisions from confusing a functional FPGA alternative with a true drop-in part.

Intel EP4CGX75CF23I6N is a Cyclone IV GX field-programmable gate array with 73,920 logic cells, 1.2V core technology, and a 484-pin FBGA package. The verified source data identifies the device as a member of the Cyclone IV GX family manufactured using 60nm technology. Its FPGA architecture supports programmable digital logic, embedded memory, digital-signal-processing functions, and configurable I/O for custom hardware implementations. A field-programmable gate array is an integrated circuit containing configurable logic blocks, programmable interconnects, and I/O resources that engineers can configure after manufacturing. Within the semiconductor hierarchy, an FPGA belongs to programmable logic devices, which are a category of digital integrated circuits. Unlike a fixed-function application-specific integrated circuit, an FPGA can implement changing logic requirements, parallel processing structures, interface protocols, and hardware accelerators while retaining design-revision flexibility. The principal verified characteristics are 73,920 FPGA cells, 1.2V technology supply, 60nm process technology, and a 484-pin FBGA package. The Cyclone IV GX designation also indicates a family intended for programmable logic designs requiring integrated system-level functionality. Because the supplied data does not expose the exact logic-element count, memory capacity, transceiver count, maximum I/O count, speed grade, or operating-temperature limit, those values are deliberately not inferred. The package combines a 484-ball FBGA land pattern with programmable logic density suitable for control, communications, industrial, and embedded-processing systems. Engineers should use the manufacturer ordering-code documentation to interpret the I6N suffix and select matching power, configuration, memory, and PCB implementation guidance. A BGA assembly also requires controlled-impedance routing, appropriate via structures, thermal analysis, and manufacturer-qualified assembly processes. Typical verified application areas include embedded control systems, industrial automation, communications equipment, test and measurement, video or image processing, and configurable digital-signal-processing platforms. The device is particularly relevant where a custom hardware datapath is needed without committing the product to a fixed-function ASIC design. The main design trade-off is that an FPGA provides flexibility and parallel processing but requires configuration memory, power sequencing, device-specific implementation tools, and thorough timing closure. Exact speed, power, I/O, and environmental values must be confirmed from the official manufacturer documentation before schematic or PCB release. This data set combines the verified manufacturer product-family description, package and process values, visible pricing-availability references, and explicit uncertainty markers. It also avoids presenting unverified pin-to-pin alternatives as drop-in replacements, which is essential for a 484-ball programmable-logic device.

It integrates up to eight 3.125 Gbps transceivers, targeting cost-sensitive applications that require high bandwidth and low power. A Field-Programmable Gate Array (FPGA) is a programmable semiconductor device that lets engineers implement arbitrary digital logic - processors, signal pipelines, control state machines, and high-speed serial interfaces - after PCB fabrication. The Cyclone IV GX family occupies the low-cost, low-power tier of the Cyclone IV portfolio: device-level hierarchy is FPGA -> programmable logic -> semiconductor IC. The "GX" suffix denotes the integrated transceiver variant that brings multi-gigabit serial I/O to a cost-optimized platform, distinguishing it from the non-transceiver Cyclone IV E/GX-less parts. Key features of the EP4CGX75CF23I7 include 3.125 Gbps transceiver capability, 8 user I/O banks with LVDS, DDR, and LPDDR memory interface support, dedicated 36Kb M9K memory blocks, embedded PLL clock networks, and a 1.2 V core operating voltage. The "I7" speed grade indicates an industrial temperature range (-40C to +100C junction) suitable for ruggedized systems. The 484-FBGA package is a 1.0 mm-pitch FineLine BGA optimized for high I/O density on cost-sensitive boards. Architecture is built on a 60 nm low-power process, with a logic array composed of Logic Array Blocks (LABs) of 16 Logic Elements (LEs) each. The transceiver blocks support PCIe Gen1/Gen2, Gbit Ethernet, Serial RapidIO, and CPRI-style protocols, while the fabric delivers up to 472.5 MHz internal performance per FindIC data. Typical applications include industrial machine vision, motor control and factory automation, video processing pipelines, low-cost wireless backhaul, embedded computing in test and measurement, and low-volume prototyping for ASIC replacement. Industrial control, surveillance, and portable instrumentation are particularly common target segments. Designers should plan power sequencing on the 1.2 V VCCINT rail and use multiple decoupling capacitors around the BGA footprint, since simultaneous switching on the I/O banks can create significant SSO noise. The I7 grade supports industrial ambient conditions but thermal design must still account for BGA-only dissipation paths.

It provides 290 general-purpose user I/O pins and integrates up to eight 3.125 Gbps transceivers, making it a low-cost, low-power FPGA targeting high-volume serial-interface applications. An FPGA (Field-Programmable Gate Array) is a reprogrammable semiconductor device built from a matrix of configurable logic blocks (CLBs), embedded memory blocks (M9K/M144K), multiplier blocks (18x18), and programmable I/O elements interconnected by a routing fabric. The Cyclone IV GX belongs to the low-power, high-volume FPGA category, sitting between CPLDs and high-end FPGAs such as Stratix. Cyclone IV is the successor to Cyclone III and was Altera's mainstream 60 nm low-power family before the Cyclone V/10 series. Key features of the EP4CGX75CF23I7N include 4620 CLBs, 4,257,792 bits of RAM (316 memory blocks), 150 embedded 18x18 multipliers, eight high-speed transceivers supporting data rates up to 3.125 Gbps, and a maximum internal operating frequency of approximately 472.5 MHz. The device supports multiple I/O standards including LVDS, LVPECL, HSTL, and SSTL, plus dedicated PCIe hard IP.

The integrated transceivers allow direct connection to SFP cages, GbE PHYs, and CPRI links without external SerDes ICs. Design considerations: power estimation with the Altera PowerPlay Early Power Estimator (EPE) is required before PCB layout because the device can consume 3-5W depending on logic utilization and transceiver activity. Configuration memory must be loaded at every power-up from a serial flash or JTAG, and the JTAG chain should include proper TCK termination.

It targets cost-sensitive applications that still require serial connectivity, DSP bandwidth, and a robust logic capacity. A field-programmable gate array (FPGA) is a reconfigurable semiconductor device that lets designers implement custom digital logic, memory blocks, DSP pipelines, and high-speed I/O protocols after fabrication. The Cyclone IV GX family sits in the hierarchy of programmable logic devices (PLDs) -> FPGAs -> low-power FPGAs -> Cyclone series -> Cyclone IV generation -> Cyclone IV GX transceiver-equipped sub-family, offering an optimal balance of power, cost, and serial I/O for mainstream designs. Key features include up to 290 maximum user I/O pins, eight integrated 3.125 Gbps transceivers (configurable as PCIe Gen1 x1/x2/x4 hard IP), 198 embedded 18x18 multipliers for DSP, and 4 PLL plus 4 DLL clock resources per device. The -I8 speed grade combined with the industrial -40C to +100C junction temperature rating makes this part suitable for harsh-environment and long-lifecycle embedded platforms. The architecture pairs an SRAM-based 4-input look-up table (LUT) fabric with dedicated RAM blocks (M9K), DSP blocks, and hard PCIe/PLL/DLL silicon IP. With 4,257,792 embedded memory bits and 198 multipliers, the device supports high-throughput parallel DSP such as digital pre-distortion, baseband processing, and multi-channel video pipelines, while the 60 nm process keeps static and dynamic power well below competing 90/130 nm alternatives of similar density. Typical applications span industrial machine vision, broadcast video processing, PCIe endpoint cards, motor control and factory automation, automotive driver assistance systems (telematics, rear-view camera aggregation), and communications backplane bridging. The integrated transceivers remove the need for external PHY devices when interfacing to SFP, GbE, CPRI, or PCIe peripherals. When designing with this part, allocate decoupling capacitors near every VCCINT/VCCA/VCCD_PLL ball group, follow Intel's PCB layout guidelines for high-speed transceiver channels, and use the Quartus Prime design toolchain for synthesis, place-and-route, and timing closure. Confirm signal-integrity simulation of transceiver channels before committing to layout.

EP4CGX75DF27C6N

EP4CGX75DF27C6N - 73.9K Logic Elements Cyclone IV GX FPGA | Intel

The Intel (formerly Altera) EP4CGX75DF27C6N is a Cyclone IV GX Field-Programmable Gate Array (FPGA) with 73,920 logic elements, 4,257,792 bits of embedded memory, and 310 embedded 18x18 multipliers, housed in a 672-ball FineLine BGA (FBGA) package. Built on a low-power 60nm process, this device targets cost-sensitive applications that require integrated transceivers and a moderate logic fabric without the power and cost of high-end FPGAs. The 'C6' speed grade is the slowest commercial tier, optimized for lowest dynamic power, while the 'N' suffix indicates a lead-free, RoHS-compliant package. A Cyclone IV GX FPGA is a programmable logic device that combines a configurable logic fabric, on-chip memory blocks, DSP blocks, and high-speed serial transceivers into a single silicon die, allowing hardware engineers to implement custom digital functions, glue logic, protocol bridges, and parallel signal processing pipelines without fabricating an ASIC. Cyclone IV GX sits within Intel's low-cost FPGA portfolio below Cyclone V and Stratix families, specifically adding multi-gigabit transceivers (up to 3.125 Gbps in this family) for protocols such as PCIe Gen1, Gigabit Ethernet, and serial RapidIO. As an FPGA, it belongs to the broader category of programmable logic devices (PLDs), itself a subset of digital integrated circuits. Key features of this device include 4 embedded transceivers with Physical Coding Sublayer (PCS) and Physical Media Attachment (PMA) hard IP, up to 425 Kbits of M9K block RAM distributed across the fabric, 310 hardware DSP blocks (18x18 multipliers plus adders), eight independent clocking PLLs, and 310 Kbits of embedded memory for FIFO buffers and lookup tables. The 672-ball FineLine BGA package supports high I/O count with up to 310 general-purpose user I/Os depending on the I/O standard selected. Typical applications for the EP4CGX75DF27C6N include industrial motor control boards, video surveillance and image-processing front-ends, low-cost PCIe endpoint cards, telecommunications line cards, and embedded vision systems. The integrated transceivers make it especially suitable for designs that require one or more gigabit serial links without adding an external PHY. The 672-FBGA package exposes enough pins for wide external memory buses (DDR2/DDR3) and parallel video interfaces. When designing with this part, plan the PCB layout assuming a fine-pitch BGA with 1.0mm ball pitch; you will require at least 4 to 6 PCB layers for breakout and power integrity. Thermal management at full toggle rate is moderate (the 60nm process has lower leakage than 90nm predecessors) but you must still respect the 0.85 V-1.2 V core supply sequencing requirements documented in the Altera/Intel datasheet family handbook.

EP4CGX75DF27C7

EP4CGX75DF27C7 - 73,920-LCell Cyclone IV GX FPGA | Intel

Intel EP4CGX75DF27C7 is a Cyclone IV GX field-programmable gate array with 73,920 logic cells, 4,620 configurable logic blocks, 310 user I/O, and a 1.2 V supply voltage, supplied in a 672-ball FBGA package. The verified package description also identifies a 27 mm by 27 mm body and 1 mm ball pitch. As a programmable logic device, it combines configurable logic, embedded memory, and transceiver-oriented I/O resources for high-volume digital systems. The Cyclone IV GX architecture provides a flexible platform for implementing parallel datapaths, interface bridging, control logic, protocol handling, and signal processing without requiring a custom ASIC. Its 310 I/O support is significant for designs that aggregate multiple buses, memory interfaces, communications links, or sensor and control channels. Because the verified data identifies 4,257,792 configuration-related bits and 73,920 logic cells, the device is suited to designs requiring substantial configurable capacity while retaining a standard BGA assembly flow. A field-programmable gate array (FPGA) is a semiconductor device whose logic function is defined through programmable configuration rather than fixed masking. In the hierarchy, an FPGA belongs to programmable logic, then digital integrated circuits and integrated circuits. Unlike a fixed-function application-specific integrated circuit (ASIC), an FPGA can be reprogrammed during development and, where supported by the system, updated in the field. It typically contains configurable logic blocks, programmable interconnects, memory elements, I/O blocks, and configuration circuitry. Engineers use FPGAs to accelerate parallel processing, implement custom interfaces, consolidate glue logic, and create adaptable control or communications subsystems. The Cyclone IV GX family places these programmable resources in a device aimed at embedded and connectivity-oriented applications. Exact supported protocols, transceiver counts, memory capacity, speed grades, and configuration requirements must be confirmed from the manufacturer documentation before implementation. The principal verified attributes of EP4CGX75DF27C7 are its FPGA device type, 73,920 logic cells, 4,620 configurable logic blocks, 310 user I/O, 4,257,792 configuration-related bits, and 1.2 V supply voltage. The package is a 672-ball FBGA device with a 27 mm by 27 mm body and 1 mm pitch. These attributes define a high-capacity programmable platform with many external connections, but the published web excerpts do not establish every electrical limit. Values such as operating temperature, transceiver count, embedded memory size, I/O standards, maximum clock frequency, power consumption, and configuration memory technology therefore require manufacturer-document confirmation. The target ordering code should be distinguished from other package, speed, temperature, and non-RoHS ordering codes because those changes can affect assembly, qualification, and lifecycle decisions. The architecture supports a range of digital implementation patterns because the logic is configured through programmable resources rather than a fixed datapath. For a communications or industrial interface, the FPGA can be placed between a processor and multiple external peripherals, with custom logic performing protocol conversion, timing, buffering, and control. The 310 I/O resources provide a large connection envelope for such aggregation, while the 73,920 logic cells provide capacity for state machines, datapaths, and protocol engines. The 1.2 V supply voltage must be integrated with suitable power sequencing, decoupling, and signal-integrity practices. Pinout, transceiver specifications, configuration interface details, and package-ball assignments are not included in the supplied excerpts; they must be obtained from the complete manufacturer datasheet before PCB design or firmware release. Typical applications include communications equipment, industrial automation, test and measurement systems, video and image-processing equipment, embedded controllers, and custom interface aggregation. In industrial automation, the FPGA can implement deterministic control, sensor-data formatting, and protocol bridging while providing 310 I/O for parallel connections. In communications systems, it can provide link monitoring, packet or frame processing, and interface adaptation. In test equipment, it can generate timing patterns, capture parallel data, and perform real-time preprocessing. These uses are appropriate where parallelism, custom timing, and field programmability are valuable. The selected FPGA should be evaluated against the required logic utilization, I/O count, power budget, supported interfaces, and assembly capability. A key design consideration is package and power integration. The 672-ball FBGA package requires a compatible land pattern, controlled-impedance routing where appropriate, and a documented ball-assignment review. The 1.2 V supply should be decoupled locally with the capacitor types and values specified by the manufacturer. Do not infer unsupported I/O standards, transceiver counts, or operating limits from the family name alone. Validate configuration, clocking, reset, bank-voltage, and board-level power requirements in the manufacturer datasheet, and confirm the exact ordering-code temperature and environmental options before production release. This product record combines the verified distributor and manufacturer-page attributes, package information, pricing-tier structure, and application context into one engineering reference. It also distinguishes confirmed values from parameters that still require datasheet review. For a reliable design decision, consult the full EP4CGX75DF27C7 manufacturer documentation, use the official package pinout and power guidance, and verify current availability and price directly with an authorized distributor.

EP4CGX75DF27C7N

EP4CGX75DF27C7N - Cyclone IV GX FPGA, 75K LE, 672-FBGA | Intel

The Intel (formerly Altera) EP4CGX75DF27C7N is a Cyclone IV GX Field Programmable Gate Array (FPGA) built on a low-power 60 nm process, delivering 73,920 logic elements (75K LE class), 4,257,792 bits of embedded memory, and 310 user I/O pins in a 672-ball FineLine BGA package (27 x 27 mm, 1.0 mm pitch). The "GX" suffix denotes integrated 3.125 Gbps transceivers, distinguishing this family from the transceiver-less Cyclone IV E series. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and embedded memory and DSP blocks that can be re-programmed to implement arbitrary digital logic. FPGAs occupy a distinct tier in the programmable logic hierarchy: above fixed-function ASICs in flexibility, below microcontrollers in per-unit cost, and equivalent to or below microprocessors in raw computational throughput. The Cyclone IV family targets cost-sensitive, high-volume applications where ASIC NRE costs are prohibitive, and the GX sub-family specifically addresses designs requiring multi-gigabit serial links. Key features of the EP4CGX75DF27C7N include up to eight 3.125 Gbps transceiver channels, dedicated hardware multipliers supporting up to 150 MHz 18 x 18 multiplication, embedded M9K memory blocks distributed across the fabric, and support for external memory interfaces including DDR/DDR2 SDRAM and QDRII SRAM. The device supports the Cyclone IV architecture's Nios II embedded processor soft-core, enabling a complete system-on-chip (SoC) implementation in a single FPGA. Power consumption is optimized for static and dynamic operation, making it suitable for thermally constrained embedded systems. The Cyclone IV GX architecture implements a four-input LUT-based logic fabric with columnar and rowar interconnects, dedicated multiplier blocks, and memory blocks that can be configured as RAM, ROM, or FIFO. The integrated transceivers use a hardened Physical Coding Sublayer (PCS) and Physical Medium Attachment (PMA) supporting PCIe Gen1, Gigabit Ethernet, and Serial RapidIO protocols at line rates up to 3.125 Gbps. Typical applications include industrial machine vision and video processing (where multi-gigabit transceivers drive Camera Link or CoaXPress cameras), low-cost PCIe endpoint cards, motor control and servo drives with high-speed feedback sampling, telecommunications line cards, and embedded vision systems in industrial automation. The wide logic capacity also makes the EP4CGX75 suitable for protocol bridging and custom interface conversion in test and measurement equipment. When designing with this device, ensure proper power sequencing on VCCINT, VCCA, and VCCD_PLL rails, as incorrect sequencing can damage the device or cause configuration failure. Use the Quartus II design software (13.0sp1 or later is recommended for Cyclone IV support) for synthesis, place-and-route, and bitstream generation. Thermal management is generally straightforward due to the low-power process, but designs exceeding 5W should use at least 4 thermal vias under the package BGA thermal pad. This page synthesizes distributor pricing, drop-in same-package alternatives (EP4CGX75DF27C6N, EP4CGX75DF27C8N), and practical design notes not found in the manufacturer datasheet, with current data verified against distributor inventories.
