EP1C6Q240C7N 概述
A field-programmable gate array is an integrated circuit whose logic fabric can be configured after manufacturing, unlike a fixed-function ASIC or standard logic device. The FPGA is the most flexible member of the programmable logic family, sitting above CPLDs in capacity and below high-end 28 nm and 16 nm FPGAs in complexity. Designers use FPGAs when time-to-market, reconfigurability, or parallel processing requirements outweigh the per-unit cost advantages of a fixed ASIC. In a typical system hierarchy, an FPGA belongs to “Programmable Logic ICs > FPGA > SRAM-based FPGA,” and the EP1C6 is one of the small-to-medium members of that category.
Key verified specifications from distributor and datasheet-index data include 5,980 logic elements, 92,160 RAM bits, and 185 user I/O pins in a 240-BFQFP package. As a Cyclone EP1C6 part, it provides the architectural balance of look-up-table logic, embedded memory, and multiple I/O banks. The -7 speed grade is the mainstream commercial speed option in this family, while the “N” suffix indicates a RoHS-compliant lead-free assembly. The 240-pin PQFP package has a relatively large pitch and wide availability of low-cost testing sockets, making it practical for prototype and low-to-medium volume applications.
Architecturally, the Cyclone EP1C6 uses an SRAM-based configuration fabric and must be loaded from an external configuration device or host at power-up. The device includes dedicated clock networks and multiple I/O banks, though the verified web snippets do not provide exhaustive details about PLL count, core voltage, or special transceivers. The 185 user I/O count allows a wide parallel bus to be brought out to the PCB, which is useful for SDR, motor control, and simple video capture. The 92,160 RAM bits support shallow FIFOs and line buffers, while the 5,980 logic elements implement modest state machines and datapaths.
Typical applications include industrial motor-control interfaces, video image capture and display, communication protocol bridges, and low-cost test-and-measurement controllers. Because this is an older Cyclone family, it is not recommended for new high-performance designs, but it remains relevant for legacy product sustainment, educational projects, and designs already qualified around the 240-pin BFQFP footprint. Designers evaluating it should confirm supply, thermal, and configuration requirements from the official Cyclone device handbook before committing a board.
The main design consideration for EP1C6Q240C7N is that SRAM-based FPGAs require a configuration source and a controlled power-up sequence. Use a compatible serial configuration device or host interface, and verify the core and I/O voltage rails before layout completion. Also remember that Cyclone I FPGAs are near or past end-of-life, so lifetime-buy planning is essential for production systems.

典型应用
EP1C6Q240C7N 适用于 6 应用s: Industrial Motor Control, Communication Protocol Bridge, Video Image Capture and Display, Medical Monitoring Front-End, Test and Measurement Controller, Embedded Instrumentation and Data Acquisition.
Industrial Motor Control
The EP1C6Q240C7N fits industrial motor-control systems where moderate logic density and 185 user I/O enable parallel encoder interfaces, PWM generation, and fault logic in a single FPGA. Its 5,980 logic elements implement the resolver parsing, current-loop state machines, and safe-torque-off interlock logic that would otherwise require many discrete standard-logic parts. The 92,160 RAM bits are useful for FIFO buffering between an ADC and a host microcontroller. Placed on a 240-pin BFQFP, the device can route 3.3 V control signals directly to gate-driver optocouplers without a full BGA escape pattern. The -7 speed grade is usually sufficient for PWM frequencies below a few hundred kilohertz. Industrial designers should confirm the operating-temperature grade because the standard C7N is not the extended-temperature option; choose an I-grade variant when the cabinet ambient exceeds the commercial limit.
推荐
Communication Protocol Bridge
The EP1C6Q240C7N is well suited to low-cost communication protocol bridging because it provides 185 user I/O pins for parallel buses and multiple voltage banks. Many legacy systems use the Cyclone EP1C6 to translate between FIFO-style parallel interfaces, SPI, UART, and memory-mapped buses. The 92,160 RAM bits allow modest packet FIFOs, and the 5,980 logic elements are enough to implement framing, CRC checking, and simple state-machine protocol control. The 240-BFQFP package simplifies board routing for wide buses compared to high-density BGA alternatives. The -7 speed grade supports typical bridge clock rates in the tens to low hundreds of megahertz, depending on the design. Because the verified data does not include exact I/O standard support, engineers should check the device handbook for the target voltage banks before assigning pins.
推荐
Video Image Capture and Display
In video image capture and display applications, the EP1C6Q240C7N can act as the glue logic between a CMOS image sensor, a display controller, and an external memory interface. The 185 user I/O pins can accept a parallel RGB or YUV bus plus clock and sync signals, while the 92,160 RAM bits create small line buffers for cropping or resolution conversion. The 5,980 logic elements implement timing generation, blanking insertion, and pixel formatting for simple VGA or lower-resolution displays. This FPGA is a practical choice for legacy machine-vision products that already use a 240-pin QFP layout. The -7 speed grade can handle pixel clocks in the moderate range, but the verified data does not specify maximum clock frequency, so timing should be simulated with the actual netlist before manufacturing.
推荐
Medical Monitoring Front-End
Medical monitoring equipment often uses an FPGA to time-multiplex sample streams from multiple physiological sensors before sending data to a processor. The EP1C6Q240C7N provides 5,980 logic elements and 92,160 RAM bits, enough to collect ADC samples, average signals, and detect simple alarm thresholds in real time. Its 185 user I/O lines can connect many parallel ADC channels, which is useful for multi-lead ECG or multi-parameter patient monitors. The 240-BFQFP package is easier to inspect under X-ray than BGA devices, a factor for medical PCB quality control. For medical designs, the standard C7N commercial-temperature version is typically intended for controlled indoor environments; verify system-level safety and lifecycle plans, and note that Cyclone I is not recommended for new medical equipment requiring long-termsupply.
推荐
Test and Measurement Controller
The EP1C6Q240C7N works well as a controller and timing engine in benchtop instruments such as logic analyzers, signal generators, and dataloggers. The 185 user I/O pins can connect to front-panel LEDs, rotary encoders, trigger inputs, and an acquisition ADC without adding large CPLDs. The 5,980 logic elements handle trigger detection, sequence state machines, and deep counter circuits. The 92,160 RAM bits provide small acquisition buffers or capture pre-trigger samples. For instruments with a fixed 240-pin PCB layout, the QFP package offers easy probing and revork. The -7 speed grade is usually sufficient for moderate instrument clocks; however, the verified product data does not specify timing parameters, so refer to the Intel/Altera Cyclone handbook for exact FMAX and input setup time values.
推荐
Embedded Instrumentation and Data Acquisition
For embedded data acquisition, the EP1C6Q240C7N can integrate ADC interface, sample-rate counters, and DMA-like handshaking into one programmable device. Its 5,980 logic elements can implement multichannel sequencers and simple DSP functions such as FIR filters, while the 92,160 RAM bits support local DMA descriptors or ring buffers. The 185 user I/O pins simplify connection to parallel SAR ADCs, DACs, and a host microcontroller bus. Because FPGAs perform many operations concurrently, sample acquisition, triggering, and host communication can occur without CPU overhead in the main processor. The 240-BFQFP package is convenient for two-layer boards if routing is carefully managed. For new data-acquisition designs, confirm whether remaining Cyclone I inventory meets long-term availability or plan a socket-compatible upgrade within the Cyclone family.

设计说明
Estimated: Cyclone EP1C6 FPGAs are SRAM-based and require a core supply rail plus I/O bank supplies. The exact voltage and power sequencing values were not included in the harvested distributor data, so refer to the Intel/Altera Cyclone device handbook before selecting regulators. In legacy designs, EP1C6 devices typically use a lower-voltage core rail with separate VCCIO supplies for each bank. Plan for separate decoupling capacitors near the four package sides and verify that the configuration device has the same supply domain to avoid brown-out during startup.
The EP1C6Q240C7N uses a 240-pin BFQFP package with leads on four sides. Unlike BGA packages, PQFP footprints allow visual inspection and manual rework, but fine pitch still requires careful solder-paste stencil design and pad shape matching. Place the FPGA so that all 185 user I/O signals can fan out without excessive vias, and keep the dedicated configuration pins routed to a header or configuration connector. If matching the exact package diagram is needed, the XAIPART package-svg library currently does not contain a 240-QFP key, so the 'default' package diagram is used and the physical footprint should be confirmed from the manufacturer drawing.
Do not treat an FPGA as a drop-in replacement without checking configuration and pin assignments: EP1C6 devices from different package families have different pinouts even when the density is identical. The Q240 package is pin-compatible within the same 240-BFQFP footprint, but not with EP1C6F256 BGA variants. Also verify that the unused pins are configured correctly in Quartus so they do not float to unexpected logic levels. Because the part is obsolete, include a lifetime-buy plan or a board-level migration strategy before using EP1C6Q240C7N in a new production product.
合规信息
The N suffix in the Intel/Altera ordering code indicates a lead-free/RoHS-compliant finish. Detailed REACH, halogen-free, and conflict minerals declarations were not present in the verified web data and should be requested from the manufacturer for the specific date code.
