EP4CGX50CF23C6N - Cyclone IV GX FPGA 50K LE 484-FBGA | Intel
The Intel (formerly Altera) EP4CGX50CF23C6N is a Cyclone IV GX field-programmable gate array (FPGA) with 49,888 logic elements, 2,562,048 bits of embedded memory, and 290 user I/Os, housed in a 484-ball FineLine BGA package (23 x 23 mm, 1.0 mm pitch). Built on a 60 nm low-power process, it integrates up to eight 3.125 Gbps transceivers and hardware multipliers, making it a strong fit for cost-sensitive, high-volume serial-interface designs. An FPGA is a reprogrammable logic device whose internal architecture consists of configurable logic blocks (CLBs), routing interconnects, embedded memory blocks, DSP blocks, and I/O cells. In the broader semiconductor taxonomy, FPGAs sit alongside ASICs and CPLDs as programmable logic devices (PLDs), and the Cyclone IV family specifically targets low-power, high-volume applications where designers need hardware flexibility without the NRE cost of an ASIC. The 'GX' suffix denotes the integrated transceivers, while 'CF23' identifies the 484-ball FineLine BGA package and 'C6' the speed grade. Key features include 3,118 configurable logic blocks (CLBs), 132 embedded 18x18 multipliers, four phase-locked loops (PLLs), 11 global clock networks, and 290 maximum user I/O pins. The device also provides up to eight 3.125 Gbps multi-gigabit transceivers (PCIe, Gbps Ethernet, Serial RapidIO), 2,562,048 bits of embedded RAM (RAM bits), and 56 embedded 9-Kbit M9K memory blocks. Core supply voltage is 1.2 V with separate VCCIO banks for multi-voltage I/O standards. The Cyclone IV GX architecture combines a low-leakage 60 nm process with hard PCIe and IP-core blocks, allowing designers to implement PCI Express Gen1 endpoints, multi-gigabit serial links, and parallel DSP pipelines simultaneously. The 484-ball FineLine BGA offers a 23 x 23 mm footprint with 1.0 mm ball pitch, suitable for cost-optimized multilayer PCBs with moderate layer counts and standard 4-6 mil via-in-pad escape rules. Typical applications include industrial machine vision and video bridging (PCIe Gen1, Gbps Ethernet), low-cost video processing (Camera Link, SDI), motor control and factory automation, point-of-sale and kiosk controllers, and embedded serial-interface aggregation. The combination of low static power (Quartus PowerPlay reports sub-1 W typical designs) and integrated transceivers is the main reason Cyclone IV GX remains popular for new designs and legacy Cyclone III migration paths. When designing with this device, plan I/O bank assignment against VCCIO rail planning early - mixing 1.5 V (DDR3) and 2.5 V (LVDS) banks on the same bank is not allowed. Transceiver reference clocks should use a low-jitter PLL-driven source, and JTAG chain tap-out must follow IEEE 1149.1 (JTAG) and IEEE 1532 in-system programming conventions. For thermal analysis, rely on the Altera/Intel PowerPlay early-power estimator and the device junction-to-ambient thermal resistance.

EP4CGX50CF23C7 - Cyclone IV GX FPGA 49.9K LE 484-FBGA | Intel
The Intel (formerly Altera) EP4CGX50CF23C7 is a member of the Cyclone IV GX family of low-power, high-volume Field-Programmable Gate Arrays (FPGAs) fabricated on a 60 nm process node. This device integrates 49,888 logic elements, 2,562,048 bits of embedded memory (113 Kbits per M9K block, 250 M9K blocks roughly), and a maximum of 49888 logic cells housed in a 484-ball FineLine BGA (FBGA) package. It is rated for commercial temperature operation (-0C to +85C) and supports a core supply voltage of 1.2 V with separate I/O bank voltages. An FPGA (Field-Programmable Gate Array) is a reconfigurable integrated circuit that allows designers to implement custom digital logic, signal-processing datapaths, and interface bridges after silicon fabrication. FPGAs sit within the broader category of programmable logic devices (PLDs) alongside CPLDs, and are typically deployed when time-to-market, parallel processing bandwidth, or hardware-revision flexibility outweigh the per-unit cost advantage of an application-specific standard product (ASSP). The Cyclone IV GX family specifically targets cost-sensitive, high-volume applications that still require integrated 3.125 Gbps transceivers and a rich DSP block count. Key features of the EP4CGX50CF23C7 include up to 290 user I/Os distributed across the FBGA ball grid, integrated 3.125 Gbps LVDS-capable transceivers (Cyclone IV GX branding), dedicated 18x18 hardware multipliers for DSP, and support for external memory interfaces including DDR2, DDR3, QDR II, and RLDRAM II. The 484-FBGA package provides a compact 1.0 mm ball pitch footprint with an exposed thermal pad, and the 60 nm process node delivers a typical static power figure optimized for fanless designs. The part also supports 8 channels of integrated SERDES on selected pin maps. Architecturally, the EP4CGX50CF23C7 is built on the proven Cyclone IV fabric with LABs (Logic Array Blocks) containing 16 Logic Elements per LAB, M9K embedded memory blocks supporting true dual-port operation, and dedicated DSP blocks for high-throughput multiplication. The transceiver sub-system and PLL count are binned by device density within the family, allowing this 50K-LE part to serve as a stepping stone between the smaller EP4CGX30 and the larger EP4CGX75/CGX150 density points. JTAG boundary-scan and active serial (AS) configuration modes are supported via dedicated configuration pins on the FBGA ball map. Typical applications for the EP4CGX50CF23C7 include industrial motor control, low-cost video processing and display bridging, automotive infotainment prototypes, communication protocol bridging (PCI Express Gen1 x1 root-complex or endpoint, GbE MACs), and embedded DSP front-ends for test & measurement. The integrated transceivers make it a popular choice for proprietary SERD links, while the DSP blocks accelerate FFTs and FIR filters in instrumentation. When designing with this part, plan the configuration scheme early - the MSEL pins select Active Serial (AS), Passive Serial (PS), JTAG, or Fast Passive Parallel (FPP) modes. Power-rail decoupling should follow the Quartus II Cyclone IV GX PowerPlay recommendations, with separate 1.2 V core, 2.5 V analog PLL, and per-bank VCCIO rails; never share ferrite beads between analog and digital 2.5 V domains. Signal-integrity closure for 3.125 Gbps channels requires controlled-impedance routing and AC-coupling capacitors at every transceiver pin pair.

EP4CGX50CF23C7N - Cyclone IV GX FPGA, 49K LE, 484-FBGA | Intel
The Intel (formerly Altera) EP4CGX50CF23C7N is a Cyclone IV GX field-programmable gate array (FPGA) built on a 60 nm low-power process, integrating 49,888 logic elements (LEs), 2,562,048 bits of embedded memory (RAM), and 290 user I/O pins in a 484-ball fine-pitch BGA (FBGA-484) package. The 'C7' speed grade and 'N' lead-free suffix place this device in the commercial, -40C to 85C operating range, while the embedded 3.125 Gbps transceivers make it a cost-optimized choice for low-cost serial connectivity in industrial, video, and wireless backhaul designs. A field-programmable gate array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs) connected via a programmable interconnect fabric, with embedded memory, DSP blocks, phase-locked loops (PLLs), and (in the Cyclone IV GX family) multi-gigabit transceivers (MGTs). The Cyclone IV family hierarchy sits below the high-end Stratix series and is targeted at cost- and power-sensitive volume production; within that family, the GX sub-family adds transceiver channels for PCIe Gen1, Gigabit Ethernet, and serial RapidIO. This positions the EP4CGX50CF23C7N as a 'transceiver-equipped Cyclone IV' rather than a plain logic FPGA. Key features of this OPN include 4 transceiver channels capable of 3.125 Gbps operation, 8 input / 8 output PLLs (or the Cyclone IV GX equivalent count) for clock management, up to 2.5 Mb of user RAM, and a 1.2 V core supply with 2.5 V/3.3 V-tolerant I/O. The FBGA-484 package provides high pin density for the 290 user I/O count while keeping board routing manageable on standard 4-layer FR-4. The device supports configuration via JTAG, Active Serial, and Passive Parallel modes, and includes on-chip pull-up resistors for non-volatile configuration via Altera EPCS or EPCQ flash. The Cyclone IV GX transceiver architecture is hardened for common serial protocols; up to 4 channels of PCIe Gen1 (x1/x2) hard IP, GMII/RGMII interfaces for GbE MACs, and basic serial RapidIO can be instantiated without external PHY silicon. For board designers, this means a single FPGA can implement a PCIe endpoint, a 1 Gbps Ethernet MAC, or a SRIO link with reduced BOM cost compared with using a general-purpose FPGA plus an external transceiver. Typical applications include industrial machine vision frame grabbers (using the transceivers for Camera Link HS or CoaXPress), low-cost PCIe data-acquisition cards, broadcast video processing (SDI/HDMI bridging), wireless small-cell backhaul, and prototyping of ASIC functions before tape-out. The combination of low unit cost, low static power (~450 mW typical), and integrated transceivers makes the EP4CGX50CF23C7N a frequent choice when designers need more than a microcontroller but less than a Stratix-class device. When designing with this FPGA, ensure that the transceiver reference clocks are sourced from a low-jitter oscillator (typical jitter under 1 ps RMS) and that the FPGA core decoupling uses 0.1 uF + 10 uF ceramic combinations per bank. The configuration scheme should be selected early because the FBGA package does not allow easy re-soldering of configuration-mode jumpers once PCB is assembled. This page synthesizes distributor pricing, package-level drop-in alternatives from the same Cyclone IV GX family, and practical design notes that go beyond the manufacturer datasheet to help engineers source and apply the EP4CGX50CF23C7N.

It is fabricated on a low-power 60 nm process and operates from a 1.2 V core supply. An FPGA (Field Programmable Gate Array) is a semiconductor device whose logic function is configured by the customer after manufacture, sitting in the hierarchy programmable logic device -> FPGA -> complex programmable logic device -> integrated circuit. Cyclone IV GX parts add up to eight 3.125 Gbps transceivers that handle protocols such as PCIe Gen1, Gigabit Ethernet, and CPRI, while the surrounding programmable fabric, embedded M9K memory blocks, and DSP blocks support glue logic, control planes, and signal processing. The Cyclone IV family is positioned as Intel's low-cost, low-power FPGA line for high-volume applications. Key features of the EP4CGX50CF23C8 include 49,888 logic elements (LEs), 3,118 configurable logic blocks (CLBs), 6.3 Mbits of embedded RAM distributed across M9K blocks, four PLLs, and eight 3.125 Gbps transceivers. The 1 mm pitch 484-pin FBGA (F23, 23 x 23 mm body) provides a thermally enhanced land-grid footprint suitable for industrial temperature operation and multi-layer PCB routing. Typical applications include industrial motor drive control planes, video surveillance and broadcast bridges, low-cost PCIe Gen1 endpoint cards, Gigabit Ethernet aggregation, and software-defined radio baseband processing. The combination of low static power, embedded transceivers, and a familiar Quartus Prime toolchain keeps total bill-of-materials cost low while shortening time-to-market for mid-volume designs. When designing with the EP4CGX50CF23C8, provide separate analog (VCCA) and digital (VCCINT) supplies with proper decoupling and ensure reference-clock jitter meets the transceiver specification for your chosen serial protocol. Quartus Prime supports the device for synthesis, place-and-route, and timing closure. This page synthesizes distributor pricing, same-family Cyclone IV GX alternatives, and PCB layout considerations not found in the manufacturer datasheet alone, giving engineers a single reference for evaluation and procurement.

An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and dedicated hard IP blocks that can be reprogrammed post-manufacturing to implement arbitrary digital logic. FPGAs occupy the middle ground between fixed-function ASICs and software-driven processors: they offer ASIC-level deterministic latency and parallelism while preserving the ability to iterate on hardware functionality in the field. The Cyclone IV GX family specifically targets cost-sensitive applications that require integrated transceivers without the power budget of high-end FPGAs. The EP4CGX50CF23C8N uses a 60 nm process node with a 1.2 V core supply, and supports both commercial and industrial temperature grades.

EP4CGX50CF23I7 - Cyclone IV GX FPGA, 49K LE, 484-FBGA | Intel
The Intel (formerly Altera) EP4CGX50CF23I7 is a Cyclone IV GX field-programmable gate array (FPGA) with 49,888 logic elements, 2,562,048 bits of embedded memory, and 290 user I/Os, housed in a 484-ball fine-pitch BGA package (F23, 23x23 mm). It is fabricated on a low-power 60 nm process, operates from a 1.2 V core supply, and integrates up to eight 3.125 Gbps transceivers for high-speed serial I/O, which is the defining feature of the Cyclone IV GX family. An FPGA (field-programmable gate array) is a semiconductor device built around an array of configurable logic blocks (CLBs), embedded memory blocks, programmable I/O cells, and a hierarchy of routed interconnects that can be reconfigured by the end user after manufacture. In a system hierarchy, an FPGA sits above general-purpose microcontrollers and below custom ASICs: it offers ASIC-class performance and parallelism for the data path while retaining the programmability of software-driven processors. The Cyclone IV GX family specifically targets cost-sensitive applications that need integrated multi-gigabit transceivers and moderate logic capacity without paying for a high-end Stratix-class device. Key features of the EP4CGX50CF23I7 include 50K equivalent logic elements, 220 multiplier blocks (18x18), six phase-locked loops (PLLs), and dual-configuration flash support through the Cyclone IV GX configuration subsystem. The integrated transceivers support common protocols such as PCIe Gen1, Gigabit Ethernet, CPRI/OBS, and serial RapidIO, with on-chip termination and 8B/10B encoding hardware. The architecture uses SRAM-based configuration cells loaded from external flash, JTAG, or Active Serial configuration, with built-in decompression and encryption options (AES-128). This makes the EP4CGX50CF23I7 well suited for applications that require both moderate DSP throughput and serial-link connectivity but do not need the largest Cyclone IV E variants. Typical applications include industrial video-broadcast equipment, low-end wireless baseband processing, machine-vision interfaces, PCIe endpoint cards, and protocol-bridging designs that translate between Gigabit Ethernet, CPRI, or OBSAI and a parallel backplane. Designers frequently pair the device with external DDR2/DDR3 SDRAM and serial flash for configuration. When designing with this device, pay close attention to the transceiver reference-clock routing and the decoupling network: each GXB lane requires its own AC-coupling capacitor and a clean 100 MHz or 156.25 MHz reference. The 484-FBGA package uses 1.0 mm pitch balls; PCB fabrication in at least 6 layers with micro-vias is recommended to fan out the transceiver signals without stub reflections.

EP4CGX50CF23I7N - 50K LE Cyclone IV GX FPGA, 484-FBGA | Intel
The Intel / Altera EP4CGX50CF23I7N is a Cyclone IV GX field-programmable gate array (FPGA) with 49,888 logic elements, 2,562,048 bits of embedded memory, and 3,118 configurable logic blocks (CLBs), housed in a 484-ball FineLine BGA package measuring 23 x 23 mm with 1.0 mm pitch. It is the industrial temperature variant of the EP4CGX50CF23 family and integrates 3.125 Gbps transceivers for high-speed serial I/O. An FPGA (Field-Programmable Gate Array) is a semiconductor device built from a matrix of configurable logic blocks (CLBs), embedded memory, DSP blocks, and programmable routing that the user defines after manufacture using a hardware description language. Within the power-management and digital-logic hierarchy, FPGAs sit between general-purpose microcontrollers (lower performance, fixed architecture) and application-specific integrated circuits (ASICs, highest performance, non-programmable). The Cyclone IV GX family specifically targets cost-sensitive, transceiver-rich applications such as industrial video, machine vision, and PCIe endpoint designs. Key features of the EP4CGX50CF23I7N include eight 3.125 Gbps transceiver channels, up to 290 user I/O pins, dedicated hardware multipliers for DSP, and a 1.2 V core supply. The device supports JTAG-based configuration through the standard Active Serial (AS), Passive Serial (PS), and JTAG modes, and is supported by the Quartus II / Quartus Prime design toolchain. Typical applications include industrial video bridges (Camera Link, HDMI, SDI), machine-vision frame grabbers, low-cost PCIe endpoint cards, motor-control and industrial automation interfaces, and wireless baseband pre-processing. Its transceiver-rich architecture makes it especially attractive wherever multiple multi-gigabit serial links must be aggregated without resorting to a more expensive Stratix-class device. When designing with this FPGA, careful attention must be paid to PCB layout for the transceiver channels: controlled-impedance differential pairs, length matching within the transceiver bank, and decoupling that meets Intel's reference-design guidelines are required to close the transceiver link reliably. The industrial temperature grade (-40C to +100C junction for I7 suffix) also means thermal design must assume operation up to that ambient. This page synthesizes distributor pricing, drop-in same-family and competitor alternatives, and practical design notes that go beyond the manufacturer datasheet.

Typical applications include industrial video surveillance with on-camera analytics, PCIe Gen1 endpoint cards in test equipment, broadcast video bridging (SDI to HDMI), wireless backhaul baseband processing, and motor control with high-speed feedback sampling. The combination of DSP blocks and transceivers makes the Cyclone IV GX particularly attractive for systems that previously required an FPGA plus an external transceiver PHY. When designing with this device, allocate sufficient PCB layers for power delivery - the core, PLL, transceiver, and I/O banks each require dedicated decoupling. Quartus II (or Intel Quartus Prime) software is required for synthesis, place-and-route, and bitstream generation, and the device is supported through the Cyclone IV device family in design tools.

EP4CGX50CF23I8N - 49,888 LEs Cyclone IV GX FPGA | Intel | FBGA-484
The Intel EP4CGX50CF23I8N is a Cyclone IV GX field-programmable gate array (FPGA) with 49,888 logic elements, 60nm process technology, 1.2V core supply, and a 484-pin fine-pitch BGA (FBGA-484) package. It integrates up to 8 transceiver channels capable of 3.125 Gbps operation for high-speed serial I/O, and embeds 3.4 Mbits of RAM for on-chip buffering. The device is part of the Cyclone IV GX family, targeting cost-sensitive applications requiring integrated transceivers. A Field-Programmable Gate Array (FPGA) is a semiconductor device whose digital logic, interconnects, I/O, and even analog blocks can be reconfigured by the end user after manufacturing. FPGAs sit between fixed-function ASICs (lower per-unit cost but no flexibility) and microcontrollers (software-defined but limited performance). The Cyclone IV GX family specifically targets low-power, transceiver-rich designs - bridging toward ASIC-like capability at FPGA-like NRE cost. Architecturally, the EP4CGX50CF23I8N contains logic array blocks (LABs), embedded RAM blocks, DSP blocks, and high-speed transceivers all wired through a programmable interconnect fabric. Key features include 49,888 logic elements, approximately 70 Mbits of embedded memory (per device family maximum), up to 290 user I/O pins, 8 integrated transceiver channels at up to 3.125 Gbps, support for PCI Express Gen1 x1/x2/x4 hard IP blocks, and integrated phase-locked loops (PLLs). The -I8N speed grade indicates an industrial temperature range (-40C to +100C junction) and an 8-speed-grade timing bin, balancing performance against power. Hard IP for PCIe, memory controllers, and transceivers removes soft-logic overhead, freeing fabric for application code. The Cyclone IV GX architecture uses a 60nm low-k dielectric process and supplies the core at 1.2V with separate I/O bank voltages (1.2V-3.3V) for flexible system integration. The 8-transceiver integration distinguishes the GX family from the E-only Cyclone IV GX siblings, making it preferred for protocols such as PCIe, Serial RapidIO, Gigabit Ethernet, and CPRI in wireless backhaul. JTAG-based configuration via Quartus Prime enables rapid iteration cycles. Typical applications include industrial video surveillance with on-board video analytics, low-cost PCIe endpoint cards for data acquisition, motor control and industrial automation with deterministic latency, telecommunications line cards with CPRI / OBSAI backhaul, and broadcast video bridging. The integrated transceivers also suit point-to-point microwave links and small-cell base stations where BOM minimization is critical. When designing with the EP4CGX50CF23I8N, allocate at least 6 PCB layers to manage BGA breakout, provide matched-length routing for the 3.125 Gbps transceiver channels, and respect the FPGA's recommended decoupling network (typically 0402-size ceramics near every VCC pin plus bulk tantalum or polymer capacitors). Quartus Prime design tools and Altera's HardCopy flow can migrate successful FPGA prototypes into structured ASICs for volume production.

EP4CGX50CF27C8N - Cyclone IV GX FPGA, 50K LE, FBGA-672 | Intel
The Intel (Altera) EP4CGX50CF27C8N is a member of the Cyclone IV GX family of low-power, high-functionality Field-Programmable Gate Arrays (FPGAs), offering 49,440 logic elements and integrated transceivers in a 672-ball FineLine BGA (FBGA-672) package. Built on TSMC's 60 nm low-power process, this device delivers an optimal balance of density, performance, and power for cost-sensitive applications requiring serial connectivity. The device features up to 3,118 Logic Array Blocks (LABs) and up to 310 user I/O pins, supporting a wide range of general-purpose and high-speed serial interfaces. A Field-Programmable Gate Array (FPGA) is a reprogrammable semiconductor device whose logic fabric, routing, and I/O can be configured by the end user after manufacture. FPGAs sit in the programmable-logic branch of the digital IC hierarchy: FPGA -> programmable logic -> digital IC -> integrated circuit -> semiconductor. Unlike fixed-function ASICs, FPGAs allow hardware iteration without respinning silicon, and unlike microcontrollers they implement logic in dedicated parallel hardware rather than running sequential firmware, achieving deterministic latency and high throughput. Key features of the EP4CGX50CF27C8N include 3,118 LABs, 310 user I/O pins, 2.5 Mb of embedded SRAM, integrated 3.125 Gbps transceivers for protocols such as PCIe Gen1, Gigabit Ethernet, and Serial RapidIO, hardware multipliers for DSP, and eight PLLs for clock management. The device supports configuration via passive serial, active serial, JTAG, and Fast Passive Parallel modes, enabling flexible boot options. Cyclone IV GX devices are designed for power budgets below 1.5 W in typical designs while still providing the high-speed serial capability that distinguishes the GX family from the Cyclone IV E non-transceiver variant. Architecturally, the Cyclone IV GX family shares the same core fabric as Cyclone IV E but adds 3.125 Gbps transceiver channels, 8B/10B encoders, PCIe hard IP, and a hard PCI Express Gen1 endpoint block. This integration makes the EP4CGX50CF27C8N attractive for designs that need both custom parallel logic and high-speed serial connectivity without resorting to a larger, more expensive transceiver-equipped FPGA such as Stratix. Typical applications include industrial video processing and broadcast bridging, automotive driver assistance interfaces, PCIe endpoint cards, low-cost software-defined radio front ends, motor control and industrial automation, and display controllers for medical imaging. The combination of transceiver support, moderate logic density, and low power makes the Cyclone IV GX 50 device a frequent choice for protocol bridging and I/O expansion roles. When designing with this device, ensure the FPGA power rails (VCCINT, VCCA, VCCD_PLL, VCCH_GXB for the transceivers) are sequenced per the datasheet to avoid latch-up, and that the transceiver reference clock meets the jitter requirements of the chosen protocol. Quartus II / Intel Quartus Prime is the primary toolchain, and the device is supported through Intel's Altera device legacy program since it is no longer recommended for new designs. This page synthesizes distributor pricing, package-level alternatives from the Cyclone IV GX family, and practical design notes not found in the manufacturer datasheet alone.
EP4CGX50DF23C6N - Cyclone IV GX FPGA 49,888 LE | Intel
The Intel (formerly Altera) EP4CGX50DF23C6N is a Cyclone IV GX family field-programmable gate array (FPGA) built on a low-power 60 nm process, integrating 49,888 logic elements, 3,118 configurable logic blocks (CLBs), and 2,340 Kbits of embedded RAM in a 484-ball plastic BGA (FBGA) package. It is rated for commercial temperature operation with a 1.2 V core supply and includes up to eight high-speed transceiver channels supporting data rates suitable for Gigabit Ethernet, PCIe Gen1, and Serial RapidIO protocols. A Cyclone IV GX FPGA is a programmable logic device that combines general-purpose fabric (look-up tables, flip-flops, routing, and block RAM) with hardened serial transceivers and PCIe IP, enabling cost-effective implementation of custom digital hardware, protocol bridges, and high-speed serial interfaces on a single chip. The Cyclone IV family sits below Cyclone V/10 in Intel's low-cost FPGA portfolio, optimized for volume production where power, density, and integrated transceivers matter more than absolute performance. Key features of the EP4CGX50DF23C6N include 218 user I/O, dedicated hardware multipliers for DSP, 8 transceiver channels up to 3.125 Gbps, support for external memory interfaces including DDR/DDR2/QDRII SDRAM, and JTAG-based configuration. Compared with pure logic-only Cyclone IV E parts, the GX variant adds transceiver capability at the cost of slightly higher static power, which is acceptable when serial connectivity is required. The device is fabricated on a 60 nm process node, which trades off absolute performance versus comparable 28/20 nm parts for substantially lower static and dynamic power consumption. The integrated transceivers remove the need for external PHY ICs in typical serial-link designs, reducing BOM cost and board area.

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.

EP4CGX50DF27I7 - Cyclone IV GX FPGA, 49,888 LE, 672-BGA | Intel
The Intel (formerly Altera) EP4CGX50DF27I7 is a Cyclone IV GX field-programmable gate array (FPGA) with 49,888 logic elements, 2,562,048 bits of embedded memory, and 310 user I/Os, housed in a 672-ball fine-pitch BGA (FBGA) package. 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.

EP4CGX50DF27I7N - Cyclone IV GX FPGA, 49,888 LE, 672-FBGA | Altera
The Altera (Intel) EP4CGX50DF27I7N is a low-power Cyclone IV GX field-programmable gate array (FPGA) housed in a 672-ball fine-pitch BGA package, integrating 49,888 logic elements, 2,562,048 bits of embedded memory, and 8 transceivers capable of up to 3.125 Gbps operation. It is built on a low-power 60 nm process and supports a core voltage of 1.2 V with I/O supply rails of 1.2 V to 3.3 V, delivering high functionality at the lowest static and dynamic power of any Cyclone generation to date. The device includes 310 maximum user I/O pins and supports a maximum internal clock frequency of 472.5 MHz. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing configurable logic blocks (CLBs), programmable interconnects, and dedicated hard IP blocks such as transceivers, PLLs, and memory controllers. FPGAs occupy the digital logic hierarchy between general-purpose microcontrollers (which run firmware on fixed hardware) and ASICs (which are application-specific and cannot be reprogrammed). Within Intel's portfolio, the Cyclone IV family sits below the high-end Stratix series and targets cost- and power-sensitive volume applications such as industrial control, video bridging, and wireless backhaul. Key features of the EP4CGX50DF27I7N include eight 3.125 Gbps transceiver channels, support for PCI Express Gen1 (x1, x2, x4) hard IP, dedicated DDR/DDR2/QDRII memory interfaces, and up to 129 DSP blocks for fixed- and floating-point acceleration. 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.
