EP3C16F256C8 - 15,408-L Logic Cell Cyclone III FPGA | Altera
부품 번호: EP3C16F256C8 ✗ 단종EP3C16F256C8 개요
A field-programmable gate array, or FPGA, is a programmable semiconductor that combines configurable logic blocks, memory, and input/output resources on one integrated device. An FPGA belongs to the broader programmable-logic hierarchy alongside CPLDs, while its parallel fabric supports higher logic density and more sophisticated clocking, signal processing, and communications designs than a conventional microcontroller or fixed-function logic device.
The EP3C16F256C8 provides 516,096 embedded memory bits and 15,408 logic elements. Its 168 I/O pins support interfaces and board-level connections, while the C8 suffix identifies a commercial speed-grade configuration. The specified commercial junction-temperature range is 0 °C to 85 °C. The 256-LBGA package uses ball-grid-array interconnects and surface-mount assembly, supporting compact designs with many external connections.
Its 65 nm Cyclone III architecture is intended for cost-sensitive programmable logic applications where flexible configuration, parallel processing, and moderate logic capacity are more important than the very high performance or power density associated with newer FPGA families. The advertised 402 MHz figure provides a concise indicator of the device's maximum performance class, but individual interfaces and designs operate according to their own timing constraints.
Typical uses include industrial control, communications, instrumentation, embedded processing, and general-purpose digital logic. Its 15,408 logic elements make it suitable for control architectures requiring parallel datapaths, state machines, protocol handling, and local buffering. The 504 Kb of block RAM can support moderate data buffering, packet storage, or lookup tables without relying exclusively on external memory.
Designers should verify every power rail, I/O standard, pin constraint, and timing requirement against the manufacturer datasheet before layout or programming. A 256-ball BGA also requires careful escape routing, layer-transition planning, clean supply distribution, and assembly-process control. Configuration, clocking, decoupling, and unused-pin treatment must be included in the complete design verification plan.
This page combines verified Cyclone III resource, package, speed-grade, pricing, and sourcing information with application guidance, comparison tables, and practical FPGA design notes. It also distinguishes catalog substitutions from same-package alternatives and highlights which procurement and technical details still require manufacturer-datasheet confirmation.

일반적인 애플리케이션
EP3C16F256C8 적합 용도: 6 애플리케이션s: Industrial Automation Controllers, Communications and Protocol Bridging, Data Acquisition and Instrumentation, Embedded Control and Parallel Processing, Video and Image Processing, Programmable Signal Conditioning.
Industrial Automation Controllers
EP3C16F256C8 fits industrial automation logic that needs parallel control paths, local buffering, and numerous board-level signals. Its 15,408 logic elements can implement state machines, machine sequencing, interlocks, counters, and communication-control logic, while 504 Kb of block RAM can retain operating data or packet buffers. The 168 I/O pins provide substantial connectivity for encoders, sensors, actuators, and field-bus transceivers. In a controller operating from 0 °C to 85 °C junction, the commercial C8 grade is suitable. Designers should use industrial-temperature alternatives when the calculated junction temperature can exceed that range and verify timing, I/O standards, isolation requirements, and power-supply sequencing against the manufacturer data.

Communications and Protocol Bridging
The EP3C16F256C8 is suitable for communications equipment requiring programmable protocol handling and multiple external interfaces. Its 15,408 logic elements can support parallel framing, filtering, clock-domain crossing, and packet-buffer control, while the 504 Kb of block RAM provides local storage for moderate data streams. The 168 available I/O pins allow implementation of multiple narrow interfaces or tightly integrated parallel buses when board-level timing is properly constrained. The 402 MHz maximum-frequency rating makes the device appropriate for demanding parallel datapaths, but actual interface rates depend on the selected speed grade, I/O standards, routing, and timing closure. Power, termination, clock jitter, and signal-integrity design remain critical in high-speed communication equipment.
추천
Data Acquisition and Instrumentation
EP3C16F256C8 can serve as the programmable control fabric in data-acquisition and instrumentation systems where multiple channels must be sampled, filtered, buffered, and transferred under real-time constraints. The 15,408 logic elements allow parallel acquisition control, digital filtering, calibration logic, and interface conversion to run concurrently. Its 504 Kb of embedded RAM is useful for staging samples or implementing deterministic FIFO structures, reducing pressure on external memory for moderate workloads. The 168 I/O pins support wide parallel buses and multiple sensor or converter connections. Designers must establish acquisition timing, input thresholds, clock distribution, and analog-interface isolation outside the FPGA, while using the device’s 1.2 V core supply and verified I/O requirements within the board power architecture.
추천
Embedded Control and Parallel Processing
EP3C16F256C8 is appropriate for embedded systems that benefit from deterministic parallel hardware rather than a software-only processor architecture. Fixed-function logic blocks can execute acquisition, motion, waveform, or event-processing tasks concurrently, while 15,408 logic elements provide room for configurable control pipelines and state machines. The 504 Kb of block RAM can support local instruction storage, data tables, or buffered traces without making every operation dependent on external memory latency. Its 168 I/O pins make the device practical for mixed peripheral, communication, and timing-control connections. A successful design should partition hard real-time functions from noncritical work, document timing assumptions, and verify configuration startup behavior so the system has a defined state after power application or reconfiguration.
추천
Video and Image Processing
EP3C16F256C8 can support modest parallel image-processing pipelines where deterministic pixel transport, filtering, thresholding, or frame buffering is required. The 15,408 logic elements are suitable for concurrent datapaths and control logic, and the 504 Kb of block RAM may support line buffers, lookup tables, or small frame stores. The 168 I/O pins provide enough parallel connectivity for source interfaces, memory interfaces, and control signals when the target video standard does not demand higher-resolution throughput beyond the device’s timing capabilities. Designers must treat the 402 MHz figure as a device-class maximum rather than guaranteed pixel or video-frame throughput. External memory bandwidth, color depth, resolution, and clocking must be included in timing analysis, with signal-integrity routing handled according to the selected interface standard.
추천
Programmable Signal Conditioning
EP3C16F256C8 is useful in programmable signal-conditioning systems that require parallel filters, counters, pulse processing, and interface adaptation. Logic elements can implement fixed- or configurable decision paths, while the 504 Kb of block RAM supports sample history, correlation windows, or threshold tables. With 168 I/O pins, the FPGA can connect multiple converters, timing references, and communication devices in a compact instrument. The 65 nm Cyclone III implementation provides a cost-focused programmable-logic platform for designs that do not require a newer device’s higher density or power efficiency. Engineering validation should include input-slew assumptions, clock-jitter analysis, output drive settings, and thermal checks. Commercial operation is limited to the verified 0 °C to 85 °C junction range unless an industrial-temperature variant is selected.

설계 노트
Treat the F256 256-LBGA as a high-density escape-routing problem rather than copying a generic FPGA land pattern. Confirm the official ball map, pitch, solder-mask definition, and recommended footprint against the package drawing before PCB release. Preserve access to power, ground, configuration, clock, and user I/O balls; incorrect escape sequencing can create long differential or high-speed nets even when the schematic is correct. Also verify the assembly process, via-in-pad policy, X-ray inspection requirement, and board coplanarity before authorizing volume assembly.
The verified 1.2 V value identifies the core supply, but it is not a complete board-power specification. Use the manufacturer power tables to estimate core and I/O consumption at the actual speed grade, clock rate, utilization, and I/O activity. Provide separate, adequately decoupled supplies for core, auxiliary, and I/O rails if required by the device. Place the required bulk and high-frequency decoupling capacitors at the associated supply balls, minimize plane transitions, and verify sequencing, voltage tolerances, ripple, startup, and current limits rather than treating all rails as interchangeable.
Plan clock distribution and sensitive interfaces before placing the general-purpose logic. Use the shortest practical clock path, preserve symmetry where recommended, provide dedicated return paths, and isolate high-speed or switching nodes from precision timing and configuration circuitry. Although the EP3C16F256C8 has 168 user I/O pins, available banks, voltage standards, and legal combinations remain design constraints. Constrain every external pin and verify the selected I/O standard, drive strength, slew, pull-up or pull-down, and timing constraints in the compilation environment.
Do not treat the advertised 402 MHz maximum frequency as guaranteed performance for every design, and do not infer a drop-in substitution solely from matching the F256 package. Speed grade, temperature class, I/O standards, timing margins, power behavior, and configuration compatibility can all change the outcome. Before replacing EP3C16F256C8 with an EP3C16F256C7N, EP3C16F256I7N, or another listed suffix variant, compare the official ordering information and recompile the complete design with the candidate device selected.
규정 준수 정보
The verified product listing identifies EP3C16F256C8 as lead free. Explicit RoHS, REACH, halogen-free, and conflict-minerals statements were not present in the supplied excerpts, so those fields remain unknown. AEC-Q100 is treated as not applicable because this is an FPGA rather than an automotive-qualified discrete device, but project-specific automotive requirements still require separate qualification review.
