EP1C3T100A8N - 2910-LE Cyclone FPGA | Altera
MPN: EP1C3T100A8N ✗ Cuối đờiEP1C3T100A8N Tóm tắt
A field-programmable gate array, or FPGA, is a semiconductor whose digital logic is configured after manufacture. An FPGA sits between fixed-function application-specific integrated circuits and software-programmable processors. Its configurable logic blocks, embedded memory and programmable I/Os allow one physical device to implement multiple control functions, accelerate parallel algorithms, or bridge dissimilar digital interfaces. The Cyclone I architecture targets designs requiring deterministic parallel operation without the complexity of a larger programmable logic device.
The EP1C3T100A8N combines 2,910 logic elements with 58 Kb of block RAM in a surface-mount TQFP-100 package measuring 14 mm by 14 mm. Its 65 I/Os provide connections for external clocks, control signals, memory interfaces and communications peripherals. The A8 designation identifies speed grade 8 within the EP1C3 device family, while the N suffix identifies the commercial termination and packaging configuration used for the specified ordering code.
The device uses a 130 nm process and a 1.5 V core supply, characteristics that reflect the architecture of the Cyclone I generation. Block RAM can store lookup tables, packet buffers, control tables or intermediate digital data without using external memory in many compact designs. The device's 275.03 MHz figure is a key timing specification, but achievable system performance also depends on the selected logic path, I/O standards, memory configuration, clocking, timing constraints and board implementation.
Typical uses include industrial control, communications adapters, instrumentation, embedded data acquisition, sensor processing and legacy peripheral expansion. The FPGA is particularly useful when several parallel state machines, protocol engines or fixed-width arithmetic pipelines must operate deterministically. It can also implement glue logic around microcontrollers, converters and memory devices while centralizing timing and control functions in programmable hardware.
A replacement design should account for discontinued-product availability, legacy supply risk and the effort required to preserve an existing 100-pin TQFP footprint. Signal integrity, decoupling, clock jitter, I/O voltage compatibility and configuration-system startup must be reviewed before substituting another FPGA. Device migration can also require a new bitstream, timing constraints, pin-placement rules and board-level validation.
This product overview combines the Cyclone I configuration with practical procurement, replacement and design guidance. It emphasizes verified electrical and packaging attributes, same-package alternatives and implementation considerations that help engineers determine whether legacy hardware can be maintained, cloned or redesigned with minimal disruption.

Ứng dụng tiêu biểu
EP1C3T100A8N phù hợp cho 6 Áp dụngs: Industrial Control and Automation, Communications Protocol Adapter, Data Acquisition and Signal Conditioning, USB Device Interface Bridging, Sensor Fusion and Edge Processing, Instrumentation and Test Equipment.
Industrial Control and Automation
The EP1C3T100A8N fits legacy industrial-control boards that combine several parallel state machines with fixed timing. Its 2,910 logic elements can implement sequencing, interlocks, pulse counting and machine-control logic, while 58 Kb of block RAM can hold lookup tables or short operating histories. The 65 I/Os provide connectivity for encoders, limit switches, relay drivers and digital sensors. Because the device is EOL, it is best suited to maintaining installed equipment or reusing a qualified 100-pin TQFP board design after confirming grade-specific temperature and timing requirements.
Được đề xuất
Communications Protocol Adapter
The Cyclone I EP1C3T100A8N is useful in legacy protocol adapters where parallel data must be framed, buffered or converted between unrelated interfaces. Its configurable logic blocks can run CRC generation, packet filtering and byte-level sequencing in parallel, while 58 Kb of block RAM can support FIFOs and short-frame buffering. The 275.03 MHz maximum frequency provides timing headroom for synchronous interfaces, although actual throughput depends on I/O standards and board-level timing. Verify legacy interface levels, clock topology and FPGA configuration retention before deploying the device in a new communications product.
Được đề xuất
Data Acquisition and Signal Conditioning
The EP1C3T100A8N can implement parallel digital acquisition control, triggering, sample indexing and sensor-data preprocessing. Two thousand nine hundred ten logic elements are sufficient for control pipelines, digital filtering or fixed-width arithmetic, and the 58 Kb of block RAM can buffer samples between acquisition stages. Its 65 I/Os allow connection to multiplexers, ADC control logic and synchronization signals. Use the 1.5 V core supply with appropriate I/O supply arrangement, and validate timing against the sampling clock rather than relying solely on the 275.03 MHz device figure.
Được đề xuất
USB Device Interface Bridging
The EP1C3T100A8N is appropriate for legacy USB interface bridging and peripheral-control designs where programmable logic must combine endpoint handling, FIFO control and a parallel processor interface. Block RAM can implement endpoint buffers, while programmable logic can manage bus request sequencing and status flags. The 100-pin TQFP package also supports established connector and routing layouts. Because the Cyclone I device is EOL, confirm USB electrical compliance, transceiver requirements, configuration behavior and long-term procurement before committing it to a new platform.
Được đề xuất
Sensor Fusion and Edge Processing
The EP1C3T100A8N can preprocess inputs from multiple sensors by combining parallel filters, threshold logic and event detection around a host processor. Its logic capacity supports deterministic digital pipelines, and its block RAM provides local storage for calibration coefficients, feature windows and synchronization buffers. The 65 I/Os can accommodate multiple sensor buses and interrupt lines. For a new IoT or edge-computing product, a currently supported FPGA or MCU family is generally preferable; use this device when maintaining an existing 100-pin board or when its legacy timing profile is already qualified.
Được đề xuất
Instrumentation and Test Equipment
The EP1C3T100A8N fits established instrumentation designs that require deterministic sequencing, parallel stimulus generation, measurement control or timing capture. Its 2,910 logic elements can implement multiple counters, trigger conditions and digital calibration paths, while block RAM can hold measurement records or waveform fragments. The 65 I/Os support instrument-control signals, display peripherals and data acquisition components. Engineers maintaining legacy test systems should preserve the original pin constraints and verify device speed grade against the shortest timing path rather than assuming another family suffix is electrically identical.

Ghi chú thiết kế
Do not treat a matching package name as proof of automatic substitution. EP1C3T100C8N and EP1C3T100I7N use the same 100-pin TQFP format as EP1C3T100A8N, but the ordering suffix affects speed grade and potentially temperature or qualification limits. Compare the manufacturer ordering guide, pin table, I/O standards and timing constraints. Preserve the original pin assignments unless the device documentation explicitly confirms equivalence, and recompile the bitstream after any justified device change.
Implement the 1.5 V core rail as a clean, low-noise supply and connect the I/O supply domains required by the selected bank and external interface levels. Place the regulator output capacitor and local core bypass capacitors close to their respective device pins, with the ground path returning directly to the appropriate power and ground pins. Check the manufacturer's recommended capacitor values, startup sequence and I/O operating rules before finalizing rail selection.
Route clocks and high-speed interfaces as controlled-impedance nets, with short return paths and continuous reference planes. The 275.03 MHz device figure does not guarantee 275.03 MHz operation in every implemented path; clock jitter, skew, I/O delay, logic depth and external load determine realized performance. Use the manufacturer timing analyzer to check setup and hold margins, and avoid relying on automatic placement for critical high-speed interfaces without post-route analysis.
A 100-pin TQFP footprint has fine-pitch leads that require careful land geometry, solder mask and paste control. Follow the exact manufacturer package drawing rather than scaling a generic TQFP footprint. Inspect leads for bridging after assembly and verify accessible test points for the 1.5 V core, configuration pins, clock inputs and selected user I/Os. Adequate via stitching beneath exposed power structures helps reduce return-path discontinuity on multilayer boards.
Thông tin tuân thủ
The device is identified as AEC-Q100 automotive-qualified. RoHS, REACH, lead-free, halogen-free and conflict-minerals status require confirmation for the exact ordering code and current supply condition.
