EP1C6Q240C8 Visão geral
An FPGA (Field-Programmable Gate Array) is a class of programmable logic device that combines configurable logic blocks, programmable interconnect, and I/O peripherals on a single die. FPGAs occupy the top of the programmable logic hierarchy (above CPLDs) and sit alongside ASICs in the broader semiconductor landscape. The Cyclone family specifically targets cost-sensitive, high-volume applications where designers need the flexibility of programmable hardware without the unit cost of a custom ASIC. The EP1C6 (5,980 LEs) is the mid-density option in the Cyclone family, positioned between the EP1C3 (3,000 LEs) and EP1C12 (12,060 LEs) for designs that need more logic than the smallest member but do not require the full capacity of the largest.
Key features include two phase-locked loops (PLLs) for clock management, up to 185 user I/O pins, dedicated DDR SDRAM interface support, and configuration via active serial (AS), passive serial (PS), or JTAG. The device supports single-ended I/O standards such as LVTTL, LVCMOS, SSTL, and PCI, and provides bitstream encryption for design security. Power is supplied through dedicated VCCINT (1.5 V core) and VCCIO (banked I/O) rails with VCCPLL for the analog PLL circuitry.
The architecture is built around four-input look-up tables (4-LUTs) and embedded multiplier blocks, with the embedded array blocks (EABs) implementing dual-port RAM, ROM, or FIFO memory functions. The Quartus II design suite supports schematic, VHDL, and Verilog entry, and provides timing-driven compilation and the SOPC Builder tool for embedded processor integration (Nios II).
Typical applications include industrial control and factory automation, telecommunications line cards, video processing, consumer electronics, and low-cost DSP front-ends. The 240-pin PQFP footprint is well-suited to through-hole or socketed prototyping where high-density BGAs are impractical.
When designing with this device, allocate VCCINT decoupling within 100 mils of each pin pair and keep PLL analog supplies isolated with a ferrite bead. The PQFP-240 package has limited thermal dissipation; at high toggle rates, the junction temperature can rise significantly above ambient, so consider airflow or a small heatsink for continuous high-utilization designs.
This page synthesizes distributor pricing, drop-in pin-compatible alternatives from the Cyclone family, and practical PCB design guidance not found in the standalone datasheet. All alternatives share the same 240-pin QFP footprint to enable drop-in PCB reuse.

Aplicações típicas
EP1C6Q240C8 é adequado para 6 aplicaçãos: Industrial Control & Factory Automation, Telecommunications Line Cards, Video Processing & Display Controllers, Consumer Electronics & Set-Top Box Logic, Low-Cost DSP Front-End, Educational & University Lab Boards.
Industrial Control & Factory Automation
The EP1C6Q240C8 fits industrial control because its 5,980 logic elements and 185 user I/O provide headroom for multi-axis motor control state machines, encoder interfaces, and safety-logic monitoring. The 240-pin PQFP footprint supports through-hole-friendly prototyping on FR-4 control boards and the 0 to 85 C commercial range covers most factory-floor environments. Designers typically pair it with 3.3 V LVCMOS peripherals; VCCIO banks allow mixed 1.5 V/2.5 V/3.3 V I/O without level shifters. The two PLLs synthesize motor PWM clocks, and the 92 Kbit embedded RAM implements axis trajectory tables and PID lookup tables, eliminating external SRAM and reducing BOM cost in PLC and machine-vision systems.
Recomendado
Telecommunications Line Cards
The EP1C6Q240C8 was historically deployed in telecom line cards for protocol bridging, framer interfacing, and TDM switching. Its 185 I/O support LVTTL/LVCMOS/SSTL standards commonly found on T1/E1 framer ICs, and the dedicated PLL resources generate the 1.544 MHz / 2.048 MHz TDM clocks from a single system reference. The 92 Kbit embedded RAM implements small packet buffers and channel-association tables. For new telecom designs, however, the Cyclone family is obsolete; current line-card designs use Cyclone V or Arria series FPGAs with hardened transceivers for higher reliability and lifecycle support.
Recomendado
Video Processing & Display Controllers
Video processing boards benefit from the EP1C6Q240C8's 5,980 LEs to implement color-space conversion, frame-rate conversion, and on-screen display (OSD) overlays. The 92 Kbit embedded RAM fits several scan-line buffers for de-interlacing or alpha blending at standard definition (480i/576i). The 185 user I/O directly drive parallel RGB panels or BT.656 video ADCs/DACs, and the two PLLs generate pixel clocks from an external 27 MHz reference. The PQFP-240 package is convenient for prototype video breakout boards, but production designs targeting HD video typically require larger Cyclone IV or Cyclone V devices with embedded multipliers.
Recomendado
Consumer Electronics & Set-Top Box Logic
The EP1C6Q240C8 was widely adopted in cost-sensitive consumer electronics including set-top box glue logic, LCD TV scalar boards, and digital photo frame controllers. Its 5,980 LEs and 185 I/O fit the back-end of an MPEG-2 decoder providing HDMI/YPbPr output formatting and audio mixing. The 1.5 V core voltage reduces power dissipation for always-on consumer appliances, and the PQFP-240 package supports low-cost PCB assembly. Consumer designs should note that the part is obsolete; current equivalent density is offered by Cyclone 10 LP 10CL006 or Lattice iCE40 families with longer production windows.
Recomendado
Low-Cost DSP Front-End
Low-cost DSP front-ends such as software-defined radio (SDR) preselectors, audio effects processors, and vibration analysis cards used the EP1C6Q240C8 as a sample-rate conversion and FIR filter engine. Its 5,980 LEs and 18 embedded multiplier blocks (per Cyclone family datasheet) implement multi-channel FIR filters and Goertzel algorithms at audio rates. The 92 Kbit embedded RAM functions as a coefficient store and circular delay line. While the EP1C6 is obsolete today, the architecture illustrates how mid-density FPGAs deliver DSP functionality at ASIC-comparable unit cost when the volume is high enough.
Recomendado
Educational & University Lab Boards
University digital logic and computer architecture labs deploy the EP1C6Q240C8 because the PQFP-240 package is breadboard-friendly (with a breakout PCB) and the Cyclone architecture is well-documented in textbooks. Students implement RISC-V or MIPS cores, simple VGA controllers, and I2C/SPI peripherals using the 5,980 LEs and 185 I/O. The Quartus II Web Edition (free) supports the EP1C6 device family, and the Quartus Programmer works with the low-cost USB-Blaster cable. The obsolete status is not a barrier for educational use; universities can stock recycled or specialty-stock parts for years of lab sessions.

Notas de projeto
The EP1C6Q240C8 requires three distinct supply rails: VCCINT (1.5 V nominal, 1.425 V to 1.575 V tolerance) for core logic, VCCIO (per bank, 1.5 V to 3.3 V depending on I/O standard) for user I/O, and VCCPLL (1.5 V analog) for the two PLL blocks. Decouple each VCCINT pin pair with a 0.1 microfarad X7R ceramic placed within 100 mils of the package. Add a bulk 47 to 100 microfarad tantalum near the PQFP-240's power pins. Isolate VCCPLL from VCCINT with a ferrite bead (600 ohms at 100 MHz) and a 10 microfarad + 0.1 microfarad LC pi-filter; PLL analog noise directly degrades jitter and clock stability.
Estimated: The PQFP-240 package has a theta_JA of approximately 25 C/W with standard JEDEC four-layer PCB airflow. At 275 MHz toggle rate and 80 percent logic utilization, ICC core current is approximately 200 mA. Total power = 1.5 V x 0.20 A + I/O contribution = approximately 0.3 W plus I/O. Junction temperature rise above ambient is approximately 7.5 C, well within the 85 C commercial limit. Estimated: this assumes typical I/O activity of 50 percent; designs with sustained 100 percent switching on many I/O should add airflow. The PQFP's exposed die-pad option is not present on this part, so use copper pours on top and bottom layers tied to GND.
Route configuration signals (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0) with 50 ohm controlled impedance and keep them shorter than 50 mm when using Passive Serial mode. Place the EPCS configuration memory within 25 mm of the FPGA to meet active-serial hold-time. Use JTAG chain pinout consistent with TCK pulled to GND through 1 kilohm and TMS/TDI pulled up to VCCIO through 10 kilohm, per IEEE 1149.1 boundary-scan requirements. Reserve four GND pins under the package's perimeter for solid stitch vias forming a Faraday cage around the die.
Do not connect VCCIO banks to different voltages unless each bank's I/O standard matches the chosen VCCIO value (e.g., 3.3 V VCCIO for LVCMOS33). Mixing LVTTL 5 V tolerant signaling on this 1.5 V core device is NOT supported despite legacy Altera naming - the EP1C6 is a 1.5 V core device, not 5 V tolerant. Do not exceed 1.575 V on VCCINT or latchup will occur. Do not leave MSEL0/MSEL1 floating - they must be tied to GND or VCCIO to select AS/PS/JTAG mode. Failure to connect nSTATUS to a 10 kilohm pull-up will cause configuration to fail intermittently.
