The device operates across a commercial temperature grade and is built on a low-power 60-nm process that targets cost-sensitive, high-volume applications. This FPGA delivers up to an internal frequency of 472 MHz and supports common Cyclone IV E peripherals including embedded multipliers, PLLs, and configuration interfaces. What is a Cyclone IV E FPGA? It is a low-power, low-cost SRAM-based programmable logic device from Intel's Cyclone IV family that uses a look-up-table (LUT) fabric combined with embedded memory blocks and DSP blocks. Within the broader taxonomy it sits at FPGA -> programmable logic device (PLD) -> digital IC -> semiconductor. The 'E' suffix denotes the Enhanced logic-and-EMAC family branch optimized for general-purpose logic, motor control, broadcast, and industrial designs where power consumption must remain low but logic density cannot be compromised. Key features of the EP4CE40F29C8L include 2475 logic array blocks (LABs) grouping 39,600 logic elements, 4 embedded PLL blocks, 116 18x18 hardware multipliers for DSP workloads, and 1,161,216 bits (113 kB) of embedded SRAM. The device supports multiple I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and RSDS through its 532 user I/O pins, and integrates configuration circuitry such as active serial (AS), passive serial (PS), and JTAG modes for flexible in-system programming. Typical applications span industrial motor control, video processing bridges, low-cost ASIC prototyping, factory automation controllers, automotive infotainment front-ends, and consumer broadcast equipment. Its combination of moderate logic capacity, low static power, and a high-pin-count BGA package makes it well suited for parallel sensor aggregation, multi-axis motion control, and protocol-bridging glue logic. When designing with the EP4CE40F29C8L, verify that your PCB can accommodate the 23x23 mm FBGA-780 footprint with 1 mm ball pitch, and plan a multi-layer stack-up with continuous ground and power planes under the device. The 'C8' speed grade delivers the slowest Fmax of the family; engineers who require higher performance should select the C7 or C6 speed grade. Thermal management is generally straightforward because of the low-power 60-nm process, but engineers should still derate junction temperature for closed enclosures. This page consolidates Intel/Altera authoritative specifications, current distributor pricing as of 2026-09-10, and a curated list of drop-in alternative MPNs that share the same FBGA-780 footprint. The information gain versus the manufacturer datasheet comes from practical cross-reference analysis, design notes, and selection guidance tailored to engineers selecting a Cyclone IV E variant for production designs.
EP4CE40F29C8LN - 39,600-LUT FPGA, 532 I/O | Altera | Embedded
Altera EP4CE40F29C8LN is a Cyclone IV E field-programmable gate array (FPGA) containing 39,600 logic elements, 532 user I/O pins, and 1,161,216 bits of embedded memory in a 780-ball BGA package. Verified distributor data describes the device as a 532-I/O FPGA with 39,600 cells, while manufacturer and secondary listings identify the F29 package as a 29 mm by 29 mm, 780-ball BGA with 1 mm pitch. These resources support digital control, communications, instrumentation, industrial automation, and other reconfigurable logic designs. A field-programmable gate array is a semiconductor device built from programmable logic blocks, routing resources, memory blocks, and programmable I/O. Engineers configure these resources after PCB assembly to implement counters, state machines, interface bridges, signal-processing pipelines, and custom peripherals. In the broader hierarchy, an FPGA belongs to programmable logic devices within integrated circuits; unlike a fixed-function application-specific integrated circuit, its logic can be revised through configuration without changing the PCB. The principal EP4CE40F29C8LN resources are 39,600 logic cells, 532 I/O pins, 1,161,216 embedded memory bits, and a 780-ball BGA package. The high I/O count makes the device useful when many parallel control signals, memory interfaces, or custom I/O protocols must be concentrated in one device. The verified listings also associate the Cyclone IV E family with a 60 nm process technology and a 1.2 V core supply. Cyclone IV E devices combine programmable logic fabric with embedded memory and programmable I/O structures. This allows deterministic parallel processing and hardware-level concurrency while retaining design flexibility. Configuration data determines the logic functions and interconnections. Board-level power integrity, configuration-mode handling, decoupling, and signal integrity therefore remain central to reliable operation, particularly for a 780-ball fine-pitch package. Typical uses include industrial motor-control platforms, test and measurement equipment, communications-interface equipment, image-processing front ends, and embedded controllers. The 39,600-cell capacity suits moderate-to-large digital designs, while 532 I/O provides substantial external connectivity. Engineers can evaluate the device for parallel data acquisition, custom bus protocols, real-time control, and hardware acceleration. A key design consideration is BGA assembly: the F29 package uses 1 mm ball pitch and requires controlled PCB fabrication and assembly. Power, ground, configuration, and I/O banks must be routed using the manufacturer package guidelines, and all required supply rails must be decoupled close to their pins. Thermal, timing, and signal-integrity signoff should be completed in the supported FPGA design environment. This page combines verified manufacturer, distributor, and cross-reference evidence to summarize EP4CE40F29C8LN resources, package details, sourcing data, same-family ordering options, and explicit design considerations. Missing electrical limits and complete ball-level pinout data are marked for manufacturer-datasheet confirmation rather than inferred.

The Cyclone IV E architecture uses Look-Up Table (LUT)-based logic elements, dedicated DSP blocks for arithmetic, true dual-port M9K memory blocks, and per-lane I/O registers. The high I/O count combined with 116 hardware multipliers makes the EP4CE40F29C9L well-suited to medium-density parallel processing, video bridging, and industrial motor control where cost-per-logic-element dominates over raw performance. The -9 speed grade places it in the fastest bin of the Cyclone IV E family. Typical applications include industrial machine vision and image processing, motor control and encoder interfacing, video format conversion and bridging, low-cost ASIC prototyping, motor drive and inverter control, factory automation PLCs, and embedded display controllers. The combination of 116 multipliers and a rich IP ecosystem (DDR2/DDR3 controllers, Ethernet MACs, PCI Express soft IP) makes it broadly applicable in cost-sensitive designs. When designing with the EP4CE40F29C9L, ensure proper decoupling per Cyclone IV hardware design guidelines (typically 100 nF + 10 uF per power rail), respect JTAG chain integrity for configuration, and select a compatible configuration device such as EPCS16 or EPCQ16. The 780-ball FBGA requires reflow soldering and X-ray inspection, so PCB assembly process capability must be qualified before volume production. Thermal management is generally passive thanks to the low 60 nm process power, but junction temperature must still be verified via the Intel PowerPlay early power estimator.

Built on a 60 nm, low-k process, the device integrates 39,600 logic elements, 1,161,216 bits of embedded SRAM (equivalent to ~144 Kbytes), and 328 user I/Os, making it one of the densest members of the Cyclone IV E family that is still offered in a wire-bond-friendly U19 BGA. A Field-Programmable Gate Array (FPGA) is a type of programmable logic IC that contains an array of configurable logic blocks (CLBs), programmable interconnect, and dedicated hardware such as block RAM, DSP blocks, and PLLs. Within the broader semiconductor taxonomy, FPGAs sit alongside ASICs, microcontrollers, and DSPs as the workhorse class for parallel, high-throughput digital signal processing. Cyclone IV E specifically targets cost-sensitive, volume-driven applications where designers need ASIC-like density and DSP performance but with FPGA flexibility and faster time-to-market. Key features of the EP4CE40U19I7N include 4 PLLs for clock management, 116 embedded multipliers (18x18), 4 configurable LVDS channels (depending on speed grade), 1.0 V/1.2 V core voltage, 1.2 V/2.5 V/3.0 V/3.3 V LVCMOS/LVTTL I/O standards, and industrial-grade (-40 °C to +100 °C junction) operating range. The device supports up to ~200 MHz internal operation across common logic paths and includes dedicated hardware for DDR/DDR2/QDRII memory interfaces, which is critical for video buffering and high-bandwidth data acquisition. Architecturally, the EP4CE40U19I7N uses Altera's classic LAB (Logic Array Block) structure with 16 logic elements per LAB, an interconnect hierarchy of row/column routing, and a configuration scheme based on SRAM cells (volatile, requiring an external configuration flash such as EPCS16/EPCS64). The 7th-order speed grade ('7') plus industrial temperature range ('I') make this specific OPN suited for industrial temperature environments while preserving timing margin for cost-sensitive designs. Typical applications include industrial motor control, factory automation controllers, video surveillance and image processing pipelines, low-cost software-defined radio (SDR) baseband, medical instrumentation front-ends, and telecom line-card glue logic. The Cyclone IV E series is widely used as a bridge between MCU/CPU hosts and high-speed analog front ends, particularly where parallel LVDS or DDR memory interfaces are required. When designing with this device, plan a 4-layer PCB with continuous ground and power planes beneath the U19 BGA, follow Altera's power distribution network guidance for the 1.0 V VCCINT rail (typically a discrete switching regulator followed by LDO post-regulation), and route all LVDS pairs with 100 Ω differential impedance and matched skew. The U19 BGA uses 1.0 mm pitch, so via-in-pad with epoxy-filled planarization is recommended for clean signal return paths.

The ALM (Adaptive Logic Module) at 8 inputs allows efficient mapping of arithmetic, multiplexer, and register-rich designs, and the variable-precision DSP blocks accelerate finite-impulse-response (FIR) and FFT kernels. Typical applications for the EP4CE55F23C8N include industrial motor-control and machine-vision front-ends, video-bridge and display controllers (HDMI/VGA/LVDS bridging), communications line cards using soft SERDES and protocol bridging, and educational/hobbyist designs where cost, low static power, and Quartus tool maturity matter more than transceiver count. Designers should note that the EP4CE55F23C8N requires 1.2 V core, 2.5 V analog PLL, and bank-specific I/O supplies; the 1.0 mm-pitch BGA demands 4- or 6-layer PCBs with microvia-in-pad stackups for escape routing. Decoupling must follow the Quartus II power-supply decoupling guidelines with 0.1 µF, 0.01 µF, and bulk capacitors distributed across each supply rail. This page synthesizes distributor pricing tiers, drop-in FPGA alternatives from the same Cyclone IV E family, and practical Quartus design-flow guidance not consolidated in the manufacturer datasheet. The EP4CE55F23C8N remains an active, in-production low-power FPGA for cost-sensitive industrial, video, and embedded designs.
EP4CE55F23C9L - Cyclone IV E FPGA, 55K LE, 484-FBGA | Intel
The Intel (formerly Altera) EP4CE55F23C9L is a low-power, low-cost Cyclone IV E FPGA delivering 55,856 logic elements, 2,396,160 bits of embedded memory, and 324 user I/Os in a 484-ball FineLine BGA (FBGA) package with -40C to +85C industrial temperature grade. The 'C9' speed grade is the fastest Cyclone IV E commercial/industrial grade, while the 'L' suffix denotes the lower-leakage variant. A Field Programmable Gate Array (FPGA) is a programmable semiconductor whose logic fabric, routing, and I/O cells can be configured by the customer after manufacture. FPGAs sit at the top of the digital-logic hierarchy between standard microcontrollers (fixed-function, software-driven) and application-specific integrated circuits (ASICs, fixed-function, hardware-only). Cyclone IV E FPGAs in particular are SRAM-based devices that must be configured from an external flash on every power-up, which makes them ideal for design iteration, prototyping, and low-to-medium-volume production runs. Key features include 55,856 logic elements, 156 embedded 18x18 multipliers (for DSP), 4 PLLs, 2.5 Mb of embedded SRAM, and 324 general-purpose I/Os that support LVDS, SSTL, LVCMOS, and PCI/PCI-X interfaces. The device supports up to 200 MHz of system performance and integrates a hard memory controller for DDR/DDR2/DDR3 SDRAM, QDR II SRAM, and RLDRAM II. Hard PCIe hard IP blocks are not present on Cyclone IV E (those are Cyclone IV GX), but soft PCIe cores can be implemented in the fabric. Typical applications include industrial motor control, video processing pipelines, telecom bridging, low-cost ASIC prototyping, and embedded vision. The combination of embedded multipliers, large memory, and abundant I/O makes EP4CE55F23C9L a strong fit for parallel DSP workloads such as FIR filtering, FFT engines, and image preprocessing where a microcontroller's sequential execution model becomes a bottleneck. Design consideration: the 'L' (low-leakage) variant reduces static current versus the standard core but at the cost of slightly slower timing closure. Ensure your Quartus Prime timing analysis reflects the chosen speed grade, and budget sufficient decoupling capacitance near the BGA power balls to meet the device's dynamic current demand.

EP4CE55F23C9LN - Cyclone IV E FPGA 55K LE | Altera
The Altera EP4CE55F23C9LN is a Cyclone IV E field-programmable gate array (FPGA) with 55,856 logic elements, 2,396,160 RAM bits, and 324 user I/O, supplied in a 484-ball FBGA (F23) package. The device runs from a 1.2 V core, is built on a 60 nm process, and uses a lead-free (N) terminal finish according to Intel/Altera ordering data. A field-programmable gate array (FPGA) is a semiconductor device containing reprogrammable logic fabric and programmable routing. Designers configure the logic elements with HDL to implement parallel custom hardware rather than a fixed instruction-set processor. In the broader taxonomy, an FPGA belongs to programmable logic -> FPGA/CPLD -> integrated circuit, and Cyclone IV is a low-cost, low-power FPGA family optimized for high-volume applications. Key features include 55,856 logic elements, organized as 3,491 LAB/CLB blocks; 2,396,160 embedded RAM bits; and 324 general-purpose user I/O. The 60 nm low-power process and 1.2 V core reduce static and dynamic power versus earlier Cyclone families. The speed-grade designator and commercial temperature rating make this part a middle-cost configuration suitable for controlled-environment equipment. The EP4CE55F23 is part of the Cyclone IV E device table that shares the same 484-ball FBGA footprint across EP4CE55 package variants. The fabric uses logic array blocks, each containing sixteen logic elements, and third-party specification data lists 3,491 CLBs. It includes block RAM for data buffering, external memory interfaces, LVDS I/O support, and clock networks. The absence of hard transceivers means high-speed serial links need external PHY/transceiver devices or a different FPGA family with hardened SerDes. Typical applications include industrial motor control, software-defined radio digital front-ends, video and image processing, medical imaging front-ends, test and measurement instrumentation, and IoT edge gateways. With 324 I/O, this FPGA can connect to many ADCs, DACs, memory devices, and system buses while keeping parallel processing in hardware. When designing the 1.2 V power delivery, provide separate low-impedance rails for core and I/O and place decoupling capacitors close to the BGA balls. Because FBGA-484 uses 1 mm pitch, a four-layer PCB with via fanout under the package is recommended; use simulation or a reference design for pin assignments. Ensure configuration device and clock termination are planned before layout.
