MPN： EP1C6Q240C7 ✓ 啟用中EP1C6Q240C7 概覽
An FPGA is an integrated circuit whose logic fabric can be configured after manufacturing. In the device hierarchy, an FPGA belongs to programmable logic devices and sits above discrete glue logic in design flexibility. The Cyclone I FPGA is SRAM-based, so it must load a configuration bitstream from an external configuration device, a host processor, or a JTAG cable at power-up. Unlike an ASIC, the EP1C6Q240C7 can be reprogrammed in-system, enabling late design changes, protocol updates, and shorter development schedules for medium-volume boards.
Key features visible in verified distributor data include 5,980 logic elements, 598 logic array blocks, 92,160 total RAM bits, and 185 user I/O pins. The core logic is fabricated on a 130 nm process and operates from a 1.5 V supply, helping reduce dynamic power compared with older 2.5 V FPGAs. The 240-pin BFQFP package provides a manageable quad flat pack layout for cost-sensitive boards and manual or reflow assembly.
The device architecture consists of logic elements grouped into LABs, embedded memory blocks for distributed buffering, and programmable interconnect that connects I/O pins to the core. With 598 LABs, designers can implement counters, state machines, decoders, small soft processors, and parallel bus interfaces. The 92,160 RAM bits support FIFOs, small packet buffers, and register files without adding external SRAM. The 185 user I/Os allow a high pin count for parallel busses and chip-to-chip interfaces.
Typical applications include industrial controller I/O expansion, protocol bridging, data acquisition front ends, custom video timing generation, and FPGA prototyping. Because the part is an SRAM FPGA, it is particularly useful when the exact logic function is still evolving or when the same board must support multiple interface standards by changing only the configuration bitstream.
One important design consideration is that the core requires a clean 1.5 V supply and a valid configuration source before user I/O can operate. Designers must handle power-up sequencing, strap the mode-select pins for the intended configuration scheme, and provide a configuration clock to the EPCS or download cable. Unused I/O pins should be assigned as inputs with weak pull-ups or driven to defined levels in the Quartus project to avoid floating nodes.
This page synthesizes distributor stock signals, drop-in Intel/Altera family alternatives, comparison data, and practical design notes that are not all found in the brief distributor snippets. It is intended to help engineers quickly evaluate EP1C6Q240C7 for legacy FPGA designs and define the fastest safe migration path within the same 240-pin package.

典型應用
EP1C6Q240C7 適用於 6 應用s: Industrial Control and Automation I/O, Protocol Bridge and Serial Aggregation, Test and Measurement Data Acquisition, Medical Device Digital Interface Logic, Display and Video Timing Generation, FPGA Prototyping and Education.
Industrial Control and Automation I/O
EP1C6Q240C7 suits industrial control subsystems where designers need wide parallel I/O and deterministic hardware timing. Its 185 user I/Os can connect to 32-bit sensor busses, quadrature encoders, and multiple PWM outputs while the central CPU is relieved from real-time pin toggling. The 5,980 logic elements implement soft counters, state machines, and dead-band generators; 92,160 RAM bits provide FIFOs or small buffers for flow control between ADCs and host interfaces. The 240-pin BFQFP package simplifies board routing in industrial controllers. Best results come from registering all external inputs and avoiding asynchronous external clocks; synchronous enable signals reduce metastability and improve timing closure.
推薦
Protocol Bridge and Serial Aggregation
In protocol converters and serial aggregation boards, EP1C6Q240C7 provides a flexible fabric for UART, SPI, I2C, and parallel bus bridging. With 185 user I/Os, the FPGA can monitor several parallel processors or ASICs while creating a consolidated output stream. The 5,980 logic elements are enough for multiple serializer/deserializer state machines and FIFO controllers. Its 92,160 RAM bits can store small packet headers or status history without external SRAM. Since the core runs from 1.5 V and is SRAM-based, the same board can support different protocol personalities by loading a new configuration file, which is valuable when field upgrades must change interface behavior.
推薦
Test and Measurement Data Acquisition
For oscilloscopes, logic analyzers, and data-acquisition front ends, EP1C6Q240C7 can generate acquisition timing, trigger logic, and memory addressing in hardware. The 5,980 logic elements allow fast comparators and simple DSP functions such as digital filtering and peak detection. The 92,160 RAM bits can implement circular buffers or small waveform memories, while 185 user I/Os connect to ADCs, DACs, and host controllers. Because timing is implemented in the FPGA rather than in software, trigger latency remains deterministic. The design should use dedicated clock pins for ADC sample clocks and synchronous enables for all measurement channels to avoid channel-to-channel skew.

Medical Device Digital Interface Logic
Non-implantable medical equipment such as patient monitors, infusion pumps, and diagnostic instruments often needs a moderate amount of custom glue logic. EP1C6Q240C7 provides 185 user I/Os for connecting sensors, graphics controllers, and host processors with deterministic hardware behavior. The commercial-temperature C7 variant is appropriate only for environments within its rated temperature range; designers requiring wider ambient must select EP1C6Q240I7N. The SRAM configuration means a corrupted bitstream can halt the device until reload, so medical designs should include robust configuration monitoring and a failsafe reload path using EPCS configuration memory.
推薦
Display and Video Timing Generation
EP1C6Q240C7 can generate custom LCD/TFT timing signals including horizontal sync, vertical sync, blanking, and pixel-clock dividers. The 5,980 logic elements are sufficient for line counters, timing generators, resolution converters, and simple dithering blocks. The 92,160 RAM bits can store small scanline buffers or gamma tables, reducing the need for external video memory. With 185 I/Os, the FPGA can connect to parallel RGB interfaces, LVDS transmitters, and host processors. Timing should be generated from a clean pixel clock source, and unused video signals must be terminated correctly to avoid EMI or display artifacts.
推薦
FPGA Prototyping and Education
EP1C6Q240C7 is useful for FPGA prototyping, lab experiments, and logic design courses because it offers a usable amount of logic and I/O in a through-hole-friendly quad flat pack. The 5,980 logic elements support finite state machines, counters, simple soft-core processors, and peripheral emulation exercises. The 92,160 RAM bits let students build FIFOs and register files. Because the device is SRAM-based, a JTAG download cable can reconfigure it repeatedly without programming extra nonvolatile memory. For a classroom environment, use a board with a configuration device and provide a known-good Quartus project so the FPGA boots reliably even when the host is not connected.

設計說明
The EP1C6Q240C7 core operates from a 1.5 V supply according to family-level verified data, but the exact current consumption depends on the configured design, I/O loading, and clock activity. Provide low-impedance 1.5 V power with adequate bulk capacitance and place high-frequency ceramic capacitors near each VCC pin. Because the FPGA is SRAM-based, power must reach valid levels before configuration starts. Estimated power should be calculated with the Intel/Altera power estimator, not from a fixed datasheet current value.
This Cyclone I FPGA is volatile: it is blank after power-up until a configuration bitstream is loaded. Ensure the nCONFIG and nSTATUS pins are handled correctly, strap the MSEL pins for the desired configuration scheme, and connect an EPCS configuration device or provide a JTAG download path. Do not leave unused I/O pins undriven; in the Quartus assignment editor set unused pins to input with weak pull-up or as driven outputs to avoid floating inputs. Incorrect configuration straps are a common cause of boards that do not boot.
Because the exact 240-BFQFP land pattern is not in the XAIPART package SVG library, the page uses the default package key, and no automated pinout diagram is rendered. For schematic and layout, use the Intel/Altera Cyclone pin files and the official footprint. Place pin 1 according to the manufacturer package drawing, mirroring for bottom-side view if needed. Use multiple ground vias around the package, keep the 1.5 V core power plane continuous, and avoid routing high-speed signals directly under the FPGA unless a solid ground reference is maintained.
With 185 user I/Os, simultaneous switching outputs can cause ground bounce if many outputs switch at the same time. Register output enables and use programmable slew-rate and drive-strength settings in Quartus for each I/O standard. Keep clock pins isolated from noisy output rows and use dedicated clock input pins for the system clock. For parallel bus interfaces, adjust per-pin output delay to reduce setup and hold skew. Add series termination resistors when trace lengths exceed roughly one inch or when the datasheet I/O standard recommends source termination.
合規資訊
Compliance status is not stated in the verified web data. The absence of an N suffix in EP1C6Q240C7 suggests it may not be the lead-free variant; choose EP1C6Q240C7N or EP1C6Q240I7N when RoHS compliance is required.
