EP4CGX50CF23I7NAA - Cyclone IV GX FPGA, 49.9K LE, F484 | Intel

The Intel (formerly Altera) EP4CGX50CF23I7NAA is a Cyclone IV GX FPGA delivering 49,888 logic elements, 2,562,048 bits of embedded memory, and integrated 3.125 Gbps transceivers in a 484-ball FineLine BGA (F23) package with industrial-grade -40C to +100C temperature support. The Cyclone IV GX family is a low-power, high-functionality programmable logic device line from Intel FPGA. As a field-programmable gate array (FPGA), it belongs to the broader hierarchy of programmable logic devices (PLDs) -> programmable logic ICs -> logic semiconductors -> integrated circuits. Cyclone IV GX FPGAs specifically target cost-sensitive applications requiring integrated transceivers and DSP blocks, making them a staple in video bridging, industrial connectivity, and wireless infrastructure designs. Key features include 49,888 logic elements (LEs) organized into 3,136 logic array blocks (LABs), 2,562,048 bits (~2.5 Mbit) of embedded SRAM configurable as RAM, ROM, or FIFO, 132 embedded 18x18 multipliers for DSP operations, and 4 phase-locked loops (PLLs). The integrated transceivers support data rates up to 3.125 Gbps, enabling protocols such as PCI Express Gen1, Gigabit Ethernet, Serial RapidIO, and CPRI. The device operates from a 1.2V core supply with separate transceiver and I/O voltages. The F484 package is a 1.0mm pitch FineLine BGA with 484 balls, providing high-density board integration while maintaining manufacturability with standard BGA assembly processes. The I7 speed grade designates an industrial temperature range, while the 8-transceiver configuration supports multiple high-speed serial interfaces simultaneously without external PHY devices. 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. This page synthesizes distributor pricing, drop-in same-package variants, and practical design notes not found in the manufacturer datasheet alone.

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. This page synthesizes distributor pricing, drop-in alternative Cyclone IV GX variants, and practical design notes not found in the manufacturer datasheet alone, providing an engineer-ready reference for selection and sourcing.

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.

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. Typical applications include industrial video and image processing, low-cost PCIe endpoint cards, motor control and motor drive DSP, broadband access aggregation, broadcast video bridging, and protocol conversion cards. Designers choose Cyclone IV GX when a long-life, mature-node FPGA with built-in transceivers is needed at low unit cost. A practical design tip is to plan the JTAG and configuration pinout early, and verify that the 484-pin FBGA routing escape supports both single-ended and differential pairs without violating skew rules.

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 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.

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.
