The verified source data identifies the package as 484-BGA and also describes a 1 mm ball pitch. It is an FPGA IC intended for configurable digital logic, interface bridging, control processing, and high-density embedded applications. A field-programmable gate array is a semiconductor device containing programmable logic blocks, routing resources, and configurable I/O. Engineers configure the FPGA after board assembly to implement digital functions without manufacturing a custom ASIC. Within the semiconductor hierarchy, an FPGA belongs to programmable logic and is used where parallel processing, fast development, field updates, or interface flexibility justify its configuration complexity. The headline density is 55,856 cells, with 3,491 configurable logic blocks and 324 I/O pins. The product listings also identify 2,396,160 embedded memory bits and a 472.5 MHz frequency. These figures place the device in a useful middle-density class for control planes, communication interfaces, test equipment, image processing, and custom accelerators. The high pin count supports multiple parallel external interfaces within one package. The part is associated with a 60 nm Cyclone IV E architecture according to the provided comparison result for another Cyclone IV E device. The I7 ordering suffix in the verified MPN denotes the identified industrial-grade ordering variant, but exact electrical limits should be confirmed from the manufacturer ordering information. The 484-BGA package is a surface-mount package family with a dense area-array interconnect and a 1 mm pitch. Typical applications include industrial automation, motor-control coordination, communication infrastructure, test and measurement, video and imaging, and embedded control. In these systems, the FPGA can consolidate deterministic control logic, timing, protocol handling, and data processing. The 324 I/O count is especially useful when the design must connect several sensors, converters, memory devices, or communications ports. Designers should allocate power, decoupling, clock distribution, configuration storage, and signal-integrity resources before routing. BGA assembly requires controlled fabrication, and every high-speed interface must be evaluated for impedance, crosstalk, and return-path continuity. Designers should also verify the exact supported transceiver, memory-interface, voltage, temperature, and speed-grade limits in the manufacturer documentation rather than infer them from family-level descriptions. This page combines the exact distributor and manufacturer values supplied for EP4CE55F23I7 with structured package mapping, practical integration guidance, and comparison data. Where the supplied sources do not establish a specification, the result is explicitly marked rather than estimated.

A Field-Programmable Gate Array (FPGA) is a reconfigurable semiconductor device whose logic, memory, and I/O blocks can be programmed by the end user to implement arbitrary digital functions. FPGAs sit in the programmable logic layer of the digital design hierarchy - above fixed-function ASICs and microcontrollers in flexibility, below them in per-unit cost at very high volumes. Cyclone IV E is positioned for high-volume, cost-sensitive applications such as industrial control, video processing, and communications infrastructure. Key features of the EP4CE55F23I7N include 3,491 configurable logic blocks (CLBs) arranged as logic array blocks (LABs), 56 embedded 18x18 multipliers for moderate DSP throughput, 4 phase-locked loops (PLLs) for flexible clock management, and an industrial temperature rating of -40C to +100C indicated by the "I7" speed/temperature grade suffix. The device supports a variety of I/O standards including LVDS, LVCMOS, SSTL, and HSTL, and offers dedicated DDR/DDR2/QDRII memory interfaces. Architecturally, the Cyclone IV E family uses a TSMC 60 nm low-power process with 1.2 V core operation, separate programmable I/O banks that each support a mix of single-ended and differential standards, and an on-chip configuration controller that supports JTAG, AS, PS, and FPP configuration modes. Hard IP blocks such as memory controllers and PLLs reduce soft-logic overhead and improve timing closure. Typical applications include industrial machine vision, video surveillance and broadcast infrastructure, motor and motion control, automotive infotainment prototypes, wireline/wireless bridge and aggregation equipment, and medical imaging front-ends. The combination of high logic density and a generous user-I/O count makes the EP4CE55F23I7N particularly suitable for mid-range digital signal aggregation designs. When designing with this part, plan thermal dissipation carefully - the 1.0 mm pitch FBGA requires a multi-layer PCB with via-in-pad and a solid ground/power plane stack-up. Quartus II (or the Quartus Prime Lite edition) is required for synthesis, place-and-route, and timing analysis. Configuration memory size must be sized appropriately for the chosen bitstream compression setting.

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

It is specified for commercial temperature grade (0C to +85C) and supports core operation from a 1.2 V supply. The device integrates 374 maximum user I/Os, 156 embedded 18x18 multipliers, and 4 PLLs, giving engineers a balanced compute-and-IO platform for cost-sensitive applications. What is a Cyclone IV E FPGA? Cyclone IV E is the non-transceiver member of Intel's Cyclone IV family, a low-cost, low-power FPGA line architected for high-volume, power-sensitive applications such as industrial control, video processing, and consumer electronics. As an SRAM-based programmable logic device, it sits in the broader hierarchy of programmable logic (FPGA -> programmable logic -> logic IC -> integrated circuit -> semiconductor), and bridges the gap between fixed-function ASICs and microcontrollers when deterministic parallel performance is required. Key differentiating features of the EP4CE55F29C8LN include 55,856 logic elements (the mid-density option in the family), 2,396,160 bits of embedded RAM for buffering and FIFO storage, 156 hardware 18x18 multipliers that accelerate DSP and video scaling pipelines, and 4 general-purpose PLLs for clock synthesis. The device supports multiple I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and HSTL, enabling direct interfacing with DDR/DDR2 memory and a wide range of peripherals without external translation. Technically, the Cyclone IV E architecture combines Logic Array Blocks (LABs) of 16 Logic Elements each, MLABs (Memory LABs) that double as distributed RAM, and embedded M9K memory blocks. Configuration is loaded via JTAG or Active Serial (AS) modes from EPCS or EPCQ flash, with built-in decompression for compressed bitstreams. The 1.2 V core is paired with on-chip voltage regulators that accept a single 3.3 V or 2.5 V supply, simplifying power-tree design on the PCB. Typical applications include industrial motor and motion control, video bridging and image processing, telecommunications line cards, broadcast equipment, and PCIe endpoint expansion.

A field-programmable gate array (FPGA) is a semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnect, and on-chip resources such as block RAM, PLLs, and (in some families) transceivers. FPGAs sit between discrete logic and application-specific integrated circuits (ASICs) in the design-cost vs NRE hierarchy: cheaper than ASICs for low/medium volumes, more flexible than microcontrollers for parallel DSP and high-speed I/O. The Cyclone IV E family is Intel's mainstream low-power FPGA line, succeeding Cyclone III with up to 30% lower power and additional hard memory blocks. Within the family, the EP4CE6 sits at the low end of the logic-density range, designed for I/O-rich designs that do not need massive fabric. Key features of the EP4CE6E22C6N include 6,272 logic elements (LEs), 270 Kbits (approximately 33.75 KBytes) of M9K embedded RAM, 15 embedded 18x18 multipliers (DSP blocks), 2 general-purpose PLLs, and 4 user I/O banks supporting LVDS, LVCMOS, SSTL, and HSTL I/O standards. The device also exposes a 50 MHz internal oscillator for simple boot designs and supports configuration via JTAG, Active Serial (AS), and Passive Serial (PS) modes from EPCS or EPCQ flash. Its 60 nm low-k process and 1.2 V core voltage (VCCINT) deliver static power roughly 25-50% lower than Cyclone III. Typical applications include industrial control and motor drive, low-cost video processing (consumer LCD/LED controllers), USB/Ethernet bridging, LED lighting controllers, automotive infotainment sub-modules, and education/hobby prototyping boards. The 144-pin EQFP package is also attractive for hand-solder-friendly prototypes and small-batch manufacturing where BGA packages are impractical. When designing with this device, ensure VCCINT decoupling uses 0.1 uF and 10 uF ceramics per bank, and respect VCCIO bank voltage grouping (1.2 V / 1.5 V / 1.8 V / 2.5 V / 3.0 V / 3.3 V) to avoid contention. For volume production, confirm lifetime supply status with Intel, since Cyclone IV E parts have transitioned from new product introduction to mature long-term-supply mode.

EP4CE6E22C7 - Cyclone IV E FPGA 6K LE, 144-LQFP | Intel/Altera
The Intel/Altera EP4CE6E22C7 is a low-power, low-cost Cyclone IV E Field-Programmable Gate Array (FPGA) with 6,272 logic elements (LEs), 91 user I/O pins, and 276,480 bits of embedded memory, housed in a 144-pin LQFP (EQFP-144) package with an exposed thermal pad. What is a Cyclone IV E FPGA? An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and embedded memory/IO blocks that the designer configures after manufacture. Cyclone IV E sits in the low-power, low-cost segment of the FPGA taxonomy (FPGA > programmable logic > logic IC > integrated circuit), making it suited to high-volume cost-sensitive applications. The EP4CE6E22C7 integrates 392 CLBs, 270 Kbits of RAM, and a rich set of embedded multipliers (15x18-bit DSP blocks) for low-end DSP workloads. Key features include 6,272 logic elements (LEs), 276,480 bits of embedded SRAM, up to 91 user I/Os with LVDS support, fifteen 18x18-bit hardware multipliers, four general-purpose PLLs, and Cyclone IV E's low-power 60 nm process. The part supports configuration via JTAG, Active Serial (AS), and Passive Serial (PS) modes, and offers commercial-grade temperature operation (0°C to +85°C junction) for the C7 speed grade. Technical depth: the EP4CE6E22C7 targets designers who need 4-6K LE density without paying for larger Cyclone IV E members (EP4CE10, EP4CE15, EP4CE22). Its four PLLs provide clock multiplication, phase shifting, and frequency synthesis; its LVDS I/O at up to 840 Mbps makes it compatible with low-speed MIPI and LVDS sensor/camera interfaces. The exposed-pad LQFP package supports both hand-soldering and reflow profiles, with 0.5 mm lead pitch. Typical applications include industrial control and factory automation, low-cost video processing pipelines, motor control and BLDC/PMSM drivers, IoT edge nodes, embedded display controllers, and low-density protocol bridges (UART/SPI/I2C to Ethernet or USB). The 91 user I/Os comfortably absorb typical glue-logic workloads and mid-density state machines. Design consideration: ensure the exposed thermal pad is soldered to a top-layer copper pour with multiple thermal vias to the ground plane, otherwise junction temperature can derate quickly at high toggle rates. For configuration, dedicate at least one 4-pin JTAG header for boundary-scan and reconfiguration.
