EP1C6Q2408N 概要
A field-programmable gate array is a semiconductor device containing a fabric of configurable logic blocks, embedded memory, and programmable I/O that can be reconfigured to implement arbitrary digital logic. FPGAs are a subclass of programmable logic devices and sit above simpler CPLDs in the digital logic hierarchy. The Cyclone family was introduced by Altera as a low-cost, high-volume FPGA platform, and this EP1C6 member is used when a design needs moderate logic density, flexible I/O standards, and parallel hardware execution without the non-recurring cost of an ASIC.
Key features of this device include 5,980 logic elements, a 1.5 V core supply optimized for the 130 nm process, and availability in a 240-pin PQFP well suited to board-level prototyping and legacy production designs. The N suffix indicates a lead-free finish in Altera ordering. As a first-generation Cyclone FPGA, the device uses SRAM-based configuration and therefore requires external configuration memory or a host controller at power-up.
From an architectural perspective, the EP1C6Q2408N integrates the Cyclone logic array, embedded RAM blocks, and programmable clock networks. The family datasheet reports a typical family speed of 275.03 MHz, with actual achievable clock rates dependent on speed grade, logic placement, and I/O standards. Because the device is SRAM-based, bitstream loading through JTAG, passive serial, or active serial configuration interfaces must be planned as part of the system design.
Typical applications include industrial motor control, factory automation, medical monitoring and imaging, display bridging, and test equipment where FPGA flexibility and deterministic hardware timing are valuable. The 240-pin PQFP allows moderate I/O counts for parallel buses, encoders, ADCs, and communication interfaces.
A key design consideration is the 1.5 V core supply: users should generate this rail with a clean regulator and place adequate decoupling close to the FPGA. Verify the exact user I/O count, RAM bits, PLL count, and temperature grade from the manufacturer pin list before finalizing the schematic because the fetched web data did not enumerate them.
This page synthesizes distributor pricing, drop-in Cyclone-family alternatives, and practical design notes not found in a single manufacturer datasheet, making it useful for engineers replacing or maintaining mature Altera Cyclone designs.

主な用途
EP1C6Q2408N の用途: 6 件s: Motor Control, Industrial Automation and PLC Replacement, Medical Imaging and Monitoring, Video and Display Bridging, Test and Measurement Instruments, Embedded Prototyping and Legacy FPGA Replacement.
Motor Control
The EP1C6Q2408N fits motor control because it provides 5,980 hardware logic elements for implementing PWM state machines, dead-time generators, and quadrature encoder counters with deterministic timing. Parallel FPGA logic can generate multi-phase PWM signals without CPU jitter, reducing vibration and audible noise compared to software timing. The 1.5 V core and 240-pin PQFP allow direct connection to gate-driver interface logic, current-sense ADCs, and encoder inputs while keeping board routing manageable. Designers should include an external configuration device such as an Altera EPCS serial flash because the FPGA is SRAM-based. The main performance benefit is low-latency loop response: the FPGA can react to overcurrent or encoder limit signals in a few clock cycles, while a processor would need interrupt latency and firmware execution time.
おすすめ
Industrial Automation and PLC Replacement
In factory automation, the EP1C6Q2408N can serve as a soft PLC or protocol-bridging engine where multiple serial buses, sensor inputs, and actuator outputs must be handled concurrently. Its 5,980 logic elements provide enough capacity for UART/SPI cores, simple fieldbus state machines, and parallel I/O expansion without burdening a host processor. The 1.5 V core and lead-free PQFP-240 package make it compatible with conventional industrial PCB manufacturing. A key benefit is design reuse: because the FPGA is reprogrammable, one board can support multiple I/O maps and protocol variants by loading a different bitstream. Practical considerations include supplying clean 1.5 V and 3.3 V rails, adding decoupling near each power pin, and verifying that the selected industrial temperature grade meets the equipment's operating range.
おすすめ
Medical Imaging and Monitoring
Medical imaging and patient monitoring front ends often need parallel signal acquisition and low-latency data preprocessing before a DSP or application processor handles image formation. The EP1C6Q2408N can implement digital filtering, decimation, frame synchronization, and sensor timing generation in programmable logic. Its 5,980 logic elements are sufficient for small ultrasound beamforming, optical coherence tomography control, or ECG/EEG channel multiplexing designs that do not require massive DSP blocks. The 240-pin PQFP provides enough I/O to connect multiple high-speed ADCs and memory devices. Because medical designs may require long product life, verify the device's lifecycle and stock availability, and maintain a configuration file backup. The FPGA's parallel architecture keeps deterministic timing for sensor sampling, reducing data skew between channels.
おすすめ
Video and Display Bridging
The EP1C6Q2408N can implement simple video bridging functions such as frame capture from a parallel camera interface, pixel clock generation, color-space conversion, and output timing to a VGA or TTL LCD panel. With 5,980 logic elements, designs can include line buffers for cropping and scaling, as well as control registers accessed by an embedded microcontroller through a parallel bus. The 1.5 V core and 240-pin QFP allow moderate pin-count memory interfaces and video connector signals on one layer-friendly package. A practical performance advantage is the FPGA's ability to generate pixel counters and sync signals in hardware, eliminating artifacts caused by CPU timing jitter. Designers should account for external configuration memory and ensure the I/O banks are powered at the correct voltage for the camera sensor and display interface.
おすすめ
Test and Measurement Instruments
Test and measurement equipment benefits from FPGA-based pattern generation, data capture, trigger logic, and protocol decoding. The EP1C6Q2408N can provide parallel data acquisition from high-speed ADCs, implement digital down-conversion filters, and manage deep acquisition memory interfaces. Its 5,980 logic elements are enough for moderate instrument designs such as logic analyzers, data loggers, or arbitrary waveform generators. The FPGA's deterministic timing allows precise trigger windows and timestamping that would be difficult to achieve with interrupt-driven processors. Because this is an older Cyclone FPGA, test equipment makers should secure sufficient lifetime stock or plan for a qualified same-family replacement. Good PCB practice includes controlled-impedance traces for high-speed I/O, bypassing every supply domain, and using the JTAG chain for board-level programming and boundary-scan testing.
おすすめ
Embedded Prototyping and Legacy FPGA Replacement
Engineers maintaining or prototyping with legacy Altera Cyclone designs often choose the EP1C6Q2408N because it fits an existing PQFP-240 board and preserves the 1.5 V core power architecture. The device can be used to prototype control logic, interface bridges, or custom peripheral controllers before committing to an ASIC. Its flexible I/O and SRAM-based reconfiguration make it easy to iterate on register maps, bus timing, and pin assignments during development. However, because this first-generation Cyclone is regarded as obsolete for new high-volume production, prototypes should be designed with the option to move to a fully compatible family variant such as EP1C6Q240C8N or to a newer low-cost FPGA if future supply risk is unacceptable. The lead-free N finish supports standard RoHS-oriented assembly lines.

設計ノート
The EP1C6Q2408N requires a 1.5 V core supply and separate I/O bank supplies. Use a low-noise voltage regulator sized for the total FPGA current plus configuration current. Estimated: for a medium-density Cyclone design, budget at least 300-500 mA for the 1.5 V rail, but verify from the power estimator because use. Place 0.1 uF ceramic capacitors close to each core power pin and bulk capacitors around the package perimeter.
The PQFP-240 package has leads on all four sides and is usually assembled with 0.5 mm pitch. Maintain solder mask and copper spacing per the board house capability, and follow the manufacturer's land pattern dimensions from the Cyclone packaging datasheet. For 275 MHz-class global clocks, keep clock inputs on dedicated clock pins and route differential clocks with controlled impedance. Avoid routing high-speed I/O edges near configuration pins because the FPGA can be disturbed during programming.
This is an SRAM-based FPGA, so verify the configuration source and scheme before board bring-up. A common pitfall is forgetting the MSEL strap pins or using the wrong JTAG voltage translation, causing the device to appear unconfigured. Also, because the EP1C6 is an older part, confirm the actual temperature grade, date code, and lifecycle status with the supplier. Do not assume that every EP1C6Q2408N-listed device has identical speed or temperature specifications if the ordering code is ambiguous.
コンプライアンス情報
