EP1C6Q240C6 Descripción general
A field-programmable gate array is a reconfigurable integrated circuit whose logic fabric and interconnects are programmed after manufacturing instead of being fixed in the silicon. FPGA sits inside the programmable logic hierarchy: FPGA -> programmable logic device -> integrated circuit -> semiconductor. Unlike a microcontroller, an FPGA executes massively parallel gate-level functions; unlike a CPLD, it achieves much larger logic capacity and typically uses SRAM-based configuration with an external boot device. The EP1C6Q240C6 belongs to the first-generation Cyclone family, designed for cost-sensitive applications that need hundreds of I/O pins and thousands of logic elements without ASIC NRE costs.
Key features of the EP1C6Q240C6 include 598 LABs representing 5,980 logic elements, 185 user I/O pins, 92,160 total RAM bits, 1.5 V core supply, and a 240-pin PQFP package with gull-wing terminals. The C6 suffix designates commercial temperature grade and speed grade 6. According to the Altera Cyclone datasheet and aggregate parametric listings, the device can sustain an internal clock frequency of 405.2 MHz, and it runs from a lower 1.5 V core rail than older 5 V/3.3 V programmable logic.
Technically, the EP1C6Q240C6 is built on a 130 nm low-cost process and is one of several density variants in the Cyclone family. The 240-pin PQFP package is a relatively large but board-friendly package for high-I/O FPGAs, offering 185 usable user I/O pins and a square footprint. Since the device is SRAM-based, it must be configured at every power-up from an external configuration device such as an Altera EPC or EPCS serial device, or be loaded through JTAG. It does not contain high-speed serial transceivers, but that is acceptable for parallel bus, control, and data-path applications.
Typical applications for the EP1C6Q240C6 include industrial control glue logic, protocol bridging between parallel buses, test instrumentation front-end logic, and teaching or prototyping platforms. Its 5,980 LEs and 185 I/O pins enable implementation of soft microcontrollers, address decoders, PWM generators, interface converters, image-sensor timing logic, and digital signal processing helper circuitry.
A key design consideration is that the FPGA core requires a clean 1.5 V rail with adequate decoupling. Equally important, because it is an SRAM FPGA, the configuration bitstream must be loaded immediately after power-up; using an EPCS configuration device or JTAG during development is mandatory. For new designs, verify the exact I/O-voltage standards and PLL resources against the full pinout tables before PCB release.

Aplicaciones típicas
EP1C6Q240C6 es adecuado para 6 aplicacións: Legacy Industrial I/O and Glue Logic Replacement, Parallel Bus Protocol Bridging, Parallel Sensor and Data Acquisition Front End, Parallel Video Timing and Image Sensor Interface, FPGA Development, Teaching and Design Reuse, Test and Measurement Instrument Logic.
Legacy Industrial I/O and Glue Logic Replacement
The EP1C6Q240C6 can replace multiple 74-series logic, small PALs, and early CPLDs in industrial controls because its 5,980 logic elements are sufficient for address decoding, bus arbitration, interlock logic, and parallel I/O expansion. The 185 user I/O pins can connect directly to optocouplers, relay drivers, and legacy buffers, while the 1.5 V core and 130 nm process reduce dynamic power compared with older 5 V logic. The 240-pin PQFP package is more reworkable and inspectable than a high-pin-count BGA, which matters for maintenance and field repair. An EPCS4SI8N serial configuration device can store the SRAM bitstream, allowing deterministic power-up. For higher ambient temperature environments, select the industrial EP1C6Q240I7N variant.
Recomendado
Parallel Bus Protocol Bridging
Cyclone FPGAs are often used to bridge parallel buses with different timing and data widths, and the EP1C6Q240C6 has enough I/O and logic for such interfaces. A designer can map an 8-bit legacy microcontroller bus to a 16-bit DSP bus, generate chip selects, insert wait states, and perform address remapping in a single device. The 185 distinguishable user I/O pins exceed the needs of most parallel bridges, leaving spare pins for status LEDs, test headers, and handshake lines. Because the device supports operation up to 405.2 MHz internally, even a moderate-speed bridge is far below the timing ceiling, reducing the risk of setup/hold violations. Use synchronous design techniques and register all crossing signals for reliable operation in noisy industrial backplanes.
Recomendado
Parallel Sensor and Data Acquisition Front End
The EP1C6Q240C6 fits into data acquisition front ends where a system must sample multiple parallel ADCs, deserialize LVCMOS sensor data, or time-stamp digital events. With 598 LABs, it can implement small FIFOs, trigger logic, counters, and a soft SPI or parallel interface to a processor. The 92,160 bits of RAM help buffer short bursts of data before transfer. The 1.5 V core voltage is comfortable for a mixed-signal board that already has 1.5 V or 1.8 V rails, but level shifting is required to drive legacy 3.3 V ADC backplanes. Use a low-jitter external oscillator for sample clocks and pay attention to simultaneous switching outputs on the 185 I/O pins by placing series resistors and limiting slew rates.
Recomendado
Parallel Video Timing and Image Sensor Interface
The EP1C6Q240C6 can implement timing generation, line buffering, and pixel preprocessing for parallel video interfaces such as legacy CMOS image sensors and VGA/XGA controllers. A typical design consumes only a few thousand logic elements for line counter, pixel clock enable, blanking generation, and small FIFOs, leaving the remaining resources for image-processing functions like thresholding or Bayer interpolation. The 185 I/O pins are enough for a 16-bit parallel sensor data bus plus sync and control signals. Because the FPGA is SRAM-based, the video timing patterns are fully re-configurable without changing PCB hardware. For video clock speeds above 100 MHz, controlled impedance traces and matched group routing are recommended, although the 240-pin PQFP package inherently has larger parasitics than a modern BGA.
Recomendado
FPGA Development, Teaching and Design Reuse
The EP1C6Q240C6 is often used in university laboratories and legacy development boards because 5,980 logic elements are enough to teach combinational logic, finite state machines, counters, and simple soft processor cores. Students can observe internal signals on the 185 I/O pins using logic analyzers, and the 240-pin PQFP permits easy hand soldering during repair or experimentation. Configuration can be loaded through JTAG for interactive development or from an EPCS device for stand-alone demos. The part is not recommended for new large-scale designs, but it remains useful as a low-cost entry point if the laboratory already owns Cyclone I tooling and boards. Modern Intel/Altera Quartus software may still support older families, but verify the tool version during setup.
Recomendado
Test and Measurement Instrument Logic
For benchtop instrumentation, the EP1C6Q240C6 provides flexible digital logic for pattern generators, bit-error testing, logic analyzer trigger circuits, and bus emulation. The 5,980 logic elements can implement edge detectors, data generators, and simple sequencers, while the 185 I/O pins connect to front-end comparators and backplane interfaces. The high 405.2 MHz internal frequency enables time-interleaved counters and fine-resolution digital delay lines when constrained by an external high-frequency clock. Because test equipment often runs continuously, thermal management is important: verify the package heat dissipation under an estimated 1.5 V core current of perhaps several hundred milliamps, and provide a small airflow or copper pour if the ambient temperature is high. Add remote JTAG for production calibration updates.

Notas de diseño
The EP1C6Q240C6 core operates from a 1.5 V supply. Because it is an older 130 nm FPGA, the exact current consumption depends on logic utilization and toggle rate; a typical 5,980 LE design can draw from several hundred mA to near 1 A in the worst case. Estimated: use a supply capable of at least 1.5 A with 1.5 V output, and decouple with a 10 uF bulk capacitor plus multiple 100 nF ceramic capacitors distributed near the FPGA power pins. Separate the 1.5 V core plane from I/O banks and place ferrite beads only if I/O noise isolation is required. Confirm all unused I/O banks are tied to an appropriate voltage and not left floating.
The 240-pin PQFP has a 24 mm square body with 0.5 mm pitch, which demands careful fan-out and adequate via placement. Use a four-layer or larger board with solid ground and power planes under the package. Add bypass capacitors as close to the VCC and GND pins as possible, ideally within 5 mm of each power pin group, and use short vias to coplanar planes. For the 185 user I/O pins, keep high-speed trace lengths matched and avoid routing parallel bus lines directly under the crystal or switching regulators. If the design uses JTAG, place a 10 kOhm pull-up on TMS and TDO as recommended by Altera configuration guidelines.
Because EP1C6Q240C6 is SRAM-based, it will not operate until the configuration image is loaded. Never omit the configuration circuit or rely on an unprogrammed device during power-on. Use an EPCS serial configuration device or program through JTAG in production. Also confirm that the configuration voltage and I/O voltage standards match your selected PROM and level shifters; legacy Cyclone devices support multiple I/O standards but the bank voltage must be correct. Finally, for new designs verify that the Quartus/Quartus II software version still includes the Cyclone family, because newer tool releases may drop support for mature FPGA families.
Información de cumplimiento
The verified web data does not explicitly list RoHS/REACH status for EP1C6Q240C6. Altera's legacy N suffix normally designates lead-free/RoHS finish; this part lacks the N suffix, so its compliance is marked unknown until a material declaration or datasheet confirmation is obtained.
