EP3C10U256C7N - 10,320-Cell 437.5MHz FPGA | Altera
部品番号: EP3C10U256C7N ✓ 生産中EP3C10U256C7N 概要
A field-programmable gate array, or FPGA, is a reconfigurable semiconductor categorized within programmable logic devices, digital logic ICs, and semiconductors. Unlike a fixed-function application-specific integrated circuit, an FPGA combines programmable logic elements, memory resources, and I/O blocks in one device. Designers can implement control logic, signal processing, protocol handling, and hardware acceleration, then update the configuration to support design revisions or field adaptation.
The Cyclone III architecture provides 10,320 logic cells organized into 645 logic array blocks. With 182 available I/Os, the EP3C10U256C7N can support substantial external connectivity while retaining the low power consumption associated with a 1.15 V to 1.25 V supply range. The stated 437.5 MHz maximum frequency establishes the device's speed class, although achievable system clock rates depend on the selected logic, routing requirements, memory interface, I/O standards, and timing constraints.
This 256-LFBGA version is identified with the N suffix and uses a 256-ball surface-mount package. The package is intended for compact embedded boards where a large leaded package would be impractical. Because the density of programmable interconnect and power connections makes PCB layout and thermal design important, engineers should follow the manufacturer's pin-connection, decoupling, configuration, and PCB-layout guidance when creating a new carrier board.
Typical uses include industrial automation, data acquisition, communications infrastructure, test and measurement equipment, and embedded control systems. The combination of 10,320 logic cells and 182 I/Os suits parallel interface logic, state machines, protocol bridges, and custom signal-processing pipelines. The 1.2 V-class supply also helps reduce power requirements compared with higher-voltage programmable logic families.
The primary design consideration is configuration and power integrity. Follow the Cyclone III power-supply recommendations, place decoupling capacitors according to the manufacturer pin table, and route configuration signals away from sensitive high-speed inputs. Verify every BGA escape route, voltage level, and I/O standard before fabrication because package-level changes can invalidate an otherwise compatible design.
This product page combines the core device specifications, package constraints, application guidance, and verified same-footprint alternatives. It also highlights replacement decisions that require review of package construction, logic resources, I/O count, temperature grade, and configuration compatibility rather than relying on the family name alone.

主な用途
EP3C10U256C7N の用途: 6 件s: Industrial Data Acquisition, Programmable Logic Control, Communications Protocol Bridging, Test and Measurement Equipment, Embedded Signal Processing, Security and Access Control.
Industrial Data Acquisition
The EP3C10U256C7N fits multi-channel data-acquisition systems that require simultaneous digital control, buffering, and interface management. Its 182 I/Os provide substantial board-level connectivity, while 10,320 logic cells and 645 LABs can implement counters, acquisition state machines, trigger logic, data formatting, and communication engines. The 1.15 V to 1.25 V core range supports efficient power distribution in embedded systems. For implementation, assign I/O standards according to the external analog and digital interfaces, use the manufacturer’s configuration and power connections, and reserve board resources for the device’s full 256-LFBGA footprint.
おすすめ
Programmable Logic Control
The Cyclone III EP3C10U256C7N is appropriate for industrial control logic that combines sequencing, conditional branching, counters, and peripheral control. A 437.5 MHz device speed class provides substantial timing margin for parallel control paths, while 645 LABs and 10,320 logic cells can host several cooperating state machines. The 182 I/Os allow connection to sensors, actuators, counters, and field buses without external programmable logic. Designers should partition critical timing paths, constrain the clock domains, and verify each external interface's voltage and standard against the manufacturer pin table.
おすすめ
Communications Protocol Bridging
The EP3C10U256C7N can implement parallel-to-serial conversion, packet framing, state management, and buffer control for communications equipment. Its 10,320 logic cells allow multiple protocol engines and control blocks to operate concurrently, while 182 I/Os support parallel processors, transceivers, and memory interfaces. The 1.15 V to 1.25 V core supply helps limit system power in space-constrained equipment. Clock-domain crossings, I/O timing, and signal-integrity constraints must be reviewed carefully, while the 256-LFBGA layout should include clean power and ground distribution around the device.
おすすめ
Test and Measurement Equipment
The EP3C10U256C7N supports programmable counters, timing engines, stimulus sequencing, result processing, and display or communications control in test and measurement instruments. A 437.5 MHz speed class is useful for parallel timing logic, while 182 I/Os allow dense connection to converters, memories, relay drivers, and front-panel controllers. Its 256-LFBGA format also supports compact instrument designs, although assembly and rework processes must accommodate BGA inspection requirements. Validate timing margins, external voltage standards, and thermal performance at the highest operating frequency and I/O activity anticipated in the finished instrument.
おすすめ
Embedded Signal Processing
The EP3C10U256C7N can implement fixed-point filters, correlation functions, digital conversions, and custom data pipelines when static resources meet the design's requirements. Its 10,320 logic cells and 645 LABs provide parallel arithmetic and control blocks, while 182 I/Os support streaming data and accelerator peripherals. The 437.5 MHz device class permits pipelined implementations, although real throughput depends on logic depth, routing congestion, memory inference, and timing closure. Establish arithmetic throughput and latency targets before implementation, then confirm DSP, memory, and clock resources in the device compilation results.
おすすめ
Security and Access Control
The EP3C10U256C7N is suitable for access-control and industrial security controllers that require parallel I/O, protocol handling, event logging, and configurable logic. The 182 I/Os can connect card readers, sensors, displays, lock drivers, and network-interface components, while 10,320 logic cells support protocol state machines and control functions. The compact 256-LFBGA helps reduce board area, but security-critical designs require separate attention to access protection, configuration storage, fault handling, and lifecycle security. Validate these controls against the product's applicable system requirements rather than treating FPGA configuration alone as a security guarantee.

設計ノート
Design the board against the manufacturer’s 256-LFBGA footprint and verify every ball assignment against the EP3C10U256C7N pin-connection table. Pay particular attention to configuration pins, clock inputs, supply rails, and ground balls. Route each supply and ground connection directly to the corresponding plane or decoupling network with minimal loop area. Because a BGA footprint can look mechanically interchangeable while differing in ball-map details, do not approve the PCB until a net-by-net comparison is complete.
Follow the Cyclone III power-supply and decoupling guidance for the 1.15 V to 1.25 V core range and any auxiliary I/O rails. Place the required decoupling capacitance close to the device’s power balls and use a low-impedance distribution structure that separates noisy loads from sensitive core connections. Account for startup current, configuration-state demand, and the difference between quiescent and active power rather than sizing the supply only from average consumption.
Keep configuration, clock, and high-speed interface routes away from noisy switching nodes and maintain continuous ground references beneath signal paths. Apply the manufacturer’s recommended fanout and via rules for the 256-LFBGA, and check assembly clearances around the package. Differential or source-synchronous interfaces require length and impedance control based on the selected I/O standard. After PCB completion, compare the fabrication stack-up and BGA lands with the released package drawing to prevent footprint drift.
Do not treat a matching package name as proof that two FPGA ordering codes are interchangeable. Verify the logic-element total, LAB count, memory resources, multiplier resources, supported I/O standards, configuration method, pin definitions, timing specifications, and temperature grade. A replacement may require recompilation even when the PCB footprint is unchanged. For EP3C10U256C7N alternatives, document every suffix difference and approve the substitution before releasing the design for production.
コンプライアンス情報
No definitive RoHS, REACH, lead-free, halogen-free, or conflict-minerals declaration was identified for the exact ordering code. The N suffix alone was not treated as proof of lead-free status. AEC-Q100 is not applicable to this commercial Cyclone III FPGA ordering code.
