EP1C6Q240I8N Übersicht
What is a Cyclone FPGA? A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs) connected by programmable interconnect. The Cyclone family was Altera's first low-cost FPGA line, positioned below the Stratix series for volume, price-sensitive applications. Within the broader taxonomy: FPGA -> programmable logic -> digital IC -> semiconductor. The Cyclone family delivers ASIC-like integration with the flexibility of in-system reprogrammability via SRAM-based configuration memory.
Key features of the EP1C6Q240I8N include 5,980 logic elements, 92,160 RAM bits (20 M4K blocks of 4,608 bits each), two phase-locked loops (PLLs) for clock management, up to 185 user I/O pins, and support for LVTTL, LVCMOS, SSTL, and LVDS I/O standards. The device integrates a configuration interface supporting both JTAG and Active Serial (AS) programming modes for in-system configuration from EPCS serial configuration devices.
Architecturally, the EP1C6Q240I8N uses Altera's 4-input look-up table (LUT) logic element with embedded memory, distributed multiplier support, and dedicated I/O registers. The 130 nm process provides adequate performance up to 275 MHz internal operation, with on-die termination and slew-rate control for signal integrity in industrial environments.
Typical applications include industrial control glue logic, telecommunications interface bridging, video processing front-ends, motor-control encoder/decoder logic, low-density ASIC prototyping, and legacy parallel-bus expansion where modern low-pin-count MCUs are insufficient. The 240-PQFP package is also suitable for hand-prototyping and rework-friendly designs.
Design consideration: PQFP packages have noticeable lead inductance; for high-speed LVDS or clock signals above 100 MHz, evaluate whether a TQFP variant or a different Cyclone density is more appropriate for signal-integrity reasons.

Typische Anwendungen
EP1C6Q240I8N ist geeignet für 6 Anwendungs: Industrial Control Glue Logic, Telecommunications Interface Bridging, Video Processing Front-End, Motor Control Encoder/Decoder, Legacy Parallel-Bus Expansion, Low-Density ASIC Prototyping.
Industrial Control Glue Logic
The EP1C6Q240I8N is well-suited to industrial glue-logic integration where multiple discrete 74-series logic devices must be consolidated into a single programmable device. Its 5,980 logic elements and 185 user I/Os allow replacement of dozens of discrete gates, latches, and counters on a control board, while the industrial -40C to +100C temperature grade handles factory-floor thermal stress. The 130 nm CMOS core at 1.5 V provides reliable operation in motor-control cabinets and PLC backplanes. Engineers use Cyclone I for encoder decoding, PWM generation, and protocol translation between RS-485 and SPI peripherals.

Telecommunications Interface Bridging
In telecom line cards and base-station auxiliary boards, the EP1C6Q240I8N bridges between legacy TDM buses (E1/T1 framers, HDB3 codecs) and modern packet interfaces. Its 185 user I/Os and LVDS support enable direct connection to telecom framer ICs without external transceivers, while the two on-die PLLs synthesize the 2.048 MHz / 8.192 MHz telecom clocks from a system reference. The 240-PQFP package is hand-prototype-friendly for low-volume telecom equipment still in service. LVTTL/LVCMOS compatibility also allows direct interface to legacy 5 V-tolerant bus drivers with external clamping.
Empfohlen
Video Processing Front-End
The EP1C6Q240I8N is widely used as a video front-end processor for industrial camera and machine-vision systems where it captures ITU-R BT.656 or parallel RGB video streams, performs color-space conversion, and drives a TFT controller. The 20 M4K RAM blocks (92 Kbits) provide line-buffer memory for deinterlacing and scaling operations. At 275 MHz internal Fmax, the device can process standard-definition video (27 MHz pixel clock) with substantial headroom for filtering and OSD overlay generation. The 240-PQFP exposes enough pins for 24-bit RGB, sync, and I2C control to the panel.
Empfohlen
Motor Control Encoder/Decoder
Servo drives and stepper motor controllers use the EP1C6Q240I8N for quadrature encoder decoding, commutation table lookup, and PID control loop execution. The Cyclone I's hardware multipliers (embedded in the LE structure) handle the 16-bit multiply-accumulate operations needed for digital filtering of the position feedback loop, while the dual PLLs synthesize the high-resolution PWM carrier clocks. The industrial temperature grade supports motor-drive ambient temperatures up to +100C without thermal throttling. The PQFP-240 footprint also enables manual rework during prototyping of custom drive firmware.
Empfohlen
Legacy Parallel-Bus Expansion
Modern microcontrollers often lack enough parallel I/O for legacy industrial peripherals (ISA bus, PC/104, Centronics, IEEE-488). The EP1C6Q240I8N serves as a bus-expansion companion to a low-pin-count MCU, providing 185 user I/Os and 5,980 logic elements for protocol translation, address decoding, and timing generation. The JTAG interface allows in-field firmware updates on legacy equipment. The 240-PQFP exposes 4-5 separate I/O banks (VCCIO groups) so it can interface simultaneously to 3.3 V MCUs and 5 V peripherals without level shifters.
Empfohlen
Low-Density ASIC Prototyping
Engineers use the EP1C6Q240I8N as an FPGA prototype for low-density ASICs before committing to NRE charges. With 5,980 LEs and 92 Kbits of block RAM, it accurately models ASICs in the 30k-50k gate range. The Quartus II design flow supports ASIC migration handoff via the HardCopy II structured ASIC family. The 240-PQFP's hand-solder-friendly gull-wing leads make bring-up board revisions easy during prototype iteration. Once the ASIC is fabricated, the same PQFP footprint allows for a HardCopy II structured-ASIC drop-in replacement.

Wichtigste Unterscheidungsmerkmale
- Industrial temperature grade (-40C to +100C) (vs. EP1C6Q240C8N)
- Same PQFP-240 footprint allows density upgrade (vs. EP1C12Q240I8N)
- Speed grade -8 provides ~10-15% higher Fmax than speed grade -7 (vs. EP1C6Q240I7N)
Designhinweise
Estimated: at typical industrial utilization of 60-70% LEs toggling at 100 MHz, the EP1C6Q240I8N draws approximately 250-400 mA from the 1.5 V VCCINT rail. Use a low-noise LDO (e.g., TPS7A4501) or a switching regulator with adequate output filtering to provide VCCINT. The VCCIO banks should be powered from 3.3 V or 2.5 V depending on connected peripherals. Decouple each VCCINT pin with 0.1 uF X7R ceramic plus 10 uF bulk tantalum within 5 mm of the lead.
PQFP-240 with 0.5 mm pitch requires careful PCB layout: use 0.2 mm wide traces, 0.4 mm via pads with 0.2 mm via drills, and a 4-layer stack-up with dedicated ground and 1.5 V power planes. Place a continuous ground plane under the entire device footprint to provide low-impedance return paths. The exposed lead frame on PQFP is not electrically connected to GND - unlike QFN, do not rely on it for thermal dissipation. Use external copper pours on top and bottom layers for thermal relief.
Do not confuse the EP1C6Q240I8N with the EP1C6F256I8N (256-FBGA) or EP2C5F256I8N (Cyclone II in FBGA-256) - the PQFP and FBGA packages are not pin-compatible and require entirely different PCB layouts. Also note that Cyclone I uses 1.5 V VCCINT, while Cyclone II uses 1.2 V - mixing these on the same PCB will damage the device. Always verify the package code in the part number suffix before PCB assembly.
For Active Serial (AS) mode configuration, connect an Altera EPCS1, EPCS4, or EPCS16 serial configuration device to the DCLK, ASDO, nCSO, and DATA0 pins. Verify the configuration bitstream size does not exceed the EPCS capacity (EPCS1=1Mbit, EPCS4=4Mbit, EPCS16=16Mbit). JTAG chain ordering is critical if multiple devices share the JTAG bus - use Quartus II's JTAG chain debugger to verify IDCODE scan results during bring-up.
Compliance-Informationen
