MPN: EP1C6Q240I7N ⚠ Lần mua cuốiEP1C6Q240I7N Tóm tắt
A Field Programmable Gate Array (FPGA) is a type of integrated circuit that can be configured by the customer or designer after manufacturing to implement arbitrary digital logic functions, ranging from simple glue logic and bus bridges up to full processor subsystems. FPGAs belong to the broader hierarchy of programmable logic devices (PLDs), which include CPLDs (Complex Programmable Logic Devices) and ASIC alternatives. Cyclone family FPGAs occupy the low-power, low-cost tier of the Altera (now Intel) programmable logic lineup and are typically used in volume applications where cost-per-logic-element matters as much as raw performance.
Key features of the EP1C6Q240I7N include two phase-locked loops (PLLs) for clock management, support for multiple I/O standards (LVTTL, LVCMOS, PCI, SSTL, LVDS), dedicated multiplier blocks for DSP operations, and configuration via serial or parallel configuration schemes. The device supports up to 240 Kbits of embedded RAM distributed across M4K memory blocks, allowing efficient on-chip data buffering without consuming general-purpose logic resources.
Typical applications for this Cyclone FPGA include industrial control and factory automation, telecommunications line cards and bridges, automotive body electronics, consumer audio/video processing, and embedded DSP or motor control. Its combination of low cost, low static power, and sufficient logic capacity makes it a long-running choice for legacy designs and for new designs in the low-density logic market.
When designing with the EP1C6Q240I7N, ensure that I/O bank supply voltages match the logic-level requirements of downstream components. Use Quartus II design software for synthesis, place-and-route, and timing closure; legacy project files may need migration to a newer Quartus version to remain compatible with current OS releases.

Ứng dụng tiêu biểu
EP1C6Q240I7N phù hợp cho 6 Áp dụngs: Industrial Control and Factory Automation, Telecommunications Line Cards and Bridges, Automotive Body Electronics, Consumer Audio and Video Processing, Embedded DSP and Motor Control, Test and Measurement Instrumentation.
Industrial Control and Factory Automation
The EP1C6Q240I7N is well-suited to industrial control and factory-automation applications requiring custom glue logic, real-time I/O expansion, or protocol bridging. Its 5,980 logic elements comfortably host medium-complexity state machines, soft processors (such as the Altera Nios II/e or Nios II/s), and standard industrial protocols such as Modbus RTU, CAN, or RS-485 framing. The industrial temperature grade (-40C to +85C) and 185 user I/Os are sufficient for connecting to multiple sensor/actuator buses, HMI displays, and motor-driver feedback lines in a typical PLC or distributed I/O node. Two integrated PLLs allow deterministic clock synthesis for time-critical encoder or fieldbus interfaces without external clock-generation ICs.

Telecommunications Line Cards and Bridges
Telecom line cards and protocol-bridge designs leverage the EP1C6Q240I7N for TDM/serial aggregation, low-density packet processing, and clock-domain crossing between line-side and backplane interfaces. The 92,160 embedded RAM bits accommodate small FIFOs and lookup tables for traffic shaping or protocol conversion, while the dual PLLs can recover clocks from multiple serial bitstreams (E1/T1, SPI, I2S). LVDS support enables direct connection to high-speed serializers on legacy backplanes without external transceivers. The QFP-240 package simplifies rework and prototype bring-up compared to BGA alternatives, which is valuable in low-volume telecom equipment and field upgrades.

Automotive Body Electronics
Automotive body-electronics modules use the EP1C6Q240I7N for consolidating multiple low-speed body-control functions such as lighting controllers, door-module logic, and HVAC interfaces into a single programmable device. The 185 user I/Os and I/O-bank flexibility allow direct interfacing with 12V automotive buses through external level shifters and high-side drivers. The industrial temperature grade covers most passenger-compartment environments, though under-hood applications typically require AEC-Q100-qualified parts. Built-in multipliers are useful for sensor-signal conditioning of wheel-speed, throttle-position, or temperature-sensor inputs.

Consumer Audio and Video Processing
Consumer audio/video equipment such as A/V receivers, set-top boxes, and digital signage controllers use the EP1C6Q240I7N to implement HDMI/DVI bridge logic, audio-sample-rate conversion, video scaling pipelines, and custom OSD overlays. The embedded M4K memory blocks serve as line buffers for video upscaling/downscaling, while the dedicated multiplier blocks accelerate FIR filters and audio DSP operations. The low static-power design of Cyclone I fits consumer-electronics thermal constraints, and the QFP-240 package accommodates hand-rework during prototype development. JTAG-based configuration supports field firmware updates.
Được đề xuất
Embedded DSP and Motor Control
Motor-control and embedded DSP applications such as BLDC driver controllers, servo amplifiers, and power-converter digital controllers use the EP1C6Q240I7N to implement PWM generation, PID loops, field-oriented control (FOC), and ADC sampling synchronization. The 92 Kbits of embedded RAM accommodate lookup tables for sine/cosine and SVPWM, while the hardware multiplier blocks accelerate Clarke and Park transforms. Two PLLs provide precise switching-frequency synthesis and ADC-clock alignment for current-sense sampling. The 185 user I/Os connect to multiple gate-driver channels, encoder inputs, and analog-front-end signals.
Được đề xuất
Test and Measurement Instrumentation
Test and measurement instruments such as bench-top oscilloscopes, logic analyzers, data-acquisition systems, and protocol analyzers use the EP1C6Q240I7N for timing control, trigger sequencing, custom display rendering, and protocol-decoding pipelines. The dual PLLs can be locked to multiple reference clocks for synchronized sampling of asynchronous signals, and the LVDS I/O capability interfaces directly with high-speed ADCs. The 5,980 logic elements support a soft processor (Nios II) for instrument control and human-interface logic, while the 92 Kbits of RAM buffer pre-trigger acquisition data. The QFP-240 package is well-suited to low-volume, hand-reworkable instrumentation designs.

Ghi chú thiết kế
The EP1C6Q240I7N core operates at 1.5V and requires a low-noise regulator such as a dedicated LDO (e.g., LT1963 or TPS7A45) for the VCORE rail. I/O bank supplies (VCCIO) can be set independently per bank in the 1.5V-3.3V range; use separate decoupling capacitors (0.1 uF ceramic plus 10 uF bulk) on each VCCIO pin and the VCORE pin. Estimated quiescent current is typically 100-300 mA depending on logic utilization and switching activity; for accurate budgeting use the PowerPlay Early Power Estimator in Quartus II before final layout.
Place configuration device (EPCS or EPCQ serial flash) within 2 inches of the FPGA DATA0/DCLK/nCONFIG/nCS pins and route the configuration traces with matched lengths to minimize skew. Keep JTAG TCK, TMS, TDI, TDO away from clock and high-speed I/O traces to avoid coupling. Use a continuous ground plane on layer 2 directly under the QFP-240 to provide a low-impedance return path; route all single-ended signals over this plane. Leave at least 4 vias in the central exposed pad area if migrating to BGA-256 variants in the same family.
Do not assume Cyclone I is supported in the latest Quartus Prime releases - it requires Quartus II 13.0sp1 or 13.1 service packs as the final supporting version. When migrating from Cyclone I to Cyclone II (e.g., EP1C6Q240I7N to EP1C12Q240I7N) the core voltage drops from 1.5V to 1.2V, requiring a regulator change; verify power-rail tolerance before reusing the PCB. Also confirm configuration-device compatibility: Cyclone I uses EPCS1/EPCS4 while Cyclone II requires EPCS16 or larger depending on bitstream size.
