EP1C6Q240I7 Présentation
A field-programmable gate array is an integrated circuit whose digital logic function is not fixed at the factory. After configuration, the FPGA implements arbitrary gate-level logic, memory, state machines, and interfaces through configurable logic blocks and routing. The Cyclone family belongs to the low-cost Altera FPGA hierarchy: Cyclone FPGA -> FPGA -> programmable logic device -> semiconductor. Designers use FPGAs when changing logic without a new ASIC mask, or when adding parallel processing and custom I/O timing, is valuable.
Key features of the EP1C6Q240I7 include 5,980 logic elements arranged in 598 LABs, 20 M4K memory blocks providing 92,160 RAM bits, and 185 user I/O pins. The industrial-temperature grade provides a junction-temperature operating range of -40°C to +100°C, which suits equipment installed in uncontrolled environments. The -7 speed grade balances timing performance and static power, while the 1.5 V core voltage reduces dynamic power compared to earlier 3.3 V FPGAs. It also includes dedicated clock-management PLL resources for generating internal and external clocks.
Architecturally, the Cyclone EP1C6 is an SRAM-based FPGA, so it must be configured after power-up from an external configuration device, a host processor, or JTAG. The 130 nm low-k process gives a balance between density and cost, making it appropriate for 10K to 20K gate-class designs. No hard embedded multipliers are included in the original Cyclone family; multiply-accumulate functions are implemented in the general-purpose logic fabric when needed.
Typical applications include industrial motor-control logic, communication protocol bridging (SPI, I2C, UART, parallel buses), video timing and frame-buffer control, medical monitoring front ends, and custom glue logic for processor boards. The 185 I/O pins allow connection of external SDRAM, ADCs, DACs, microcontrollers, and display interfaces without a separate CPLD. Because the Q240 footprint is shared by several Cyclone EP1C6 derivatives, a single PCB can support multiple density and temperature-grade options.
When designing with the EP1C6Q240I7, all core VCCINT pins should be supplied with a clean 1.5 V rail and adequate decoupling. The SRAM configuration bitstream should be stored in an external serial configuration device such as an EPCS device, or loaded by a host CPU using passive serial mode. The nCONFIG and CONF_DONE pins must be handled according to the Cyclone configuration guidelines to avoid startup failures.
This page synthesizes distributor inventory, same-family drop-in alternatives, and practical configuration guidance that are not printed in a single parametric table, making it useful for engineers comparing replacement options for legacy Cyclone designs.

Applications typiques
EP1C6Q240I7 convient pour 6 applications: Industrial Motor Control, Communication Protocol Bridge, Video Timing and Display Controller, Medical Monitoring and Diagnostic Equipment, Data Acquisition and Instrumentation, FPGA Prototyping and Custom Logic Integration.
Industrial Motor Control
The EP1C6Q240I7 fits industrial motor-control applications because its industrial -40°C to +100°C junction range allows operation near drives, power stages, and factory-floor enclosures. Its 5,980 logic elements can implement three-phase PWM generators, quadrature encoder counters, overcurrent trip logic, and Modbus or CAN-like serial interfaces in parallel, removing timing pressure from the host MCU. The 185 I/O pins connect directly to gate-driver optocouplers, current-sense ADCs, and encoder inputs. Designers typically assign timer-critical PWM signals to dedicated clock pins and place the FPGA near the power board. The FPGA's SRAM-based configuration should be loaded by the host MCU at power-up, and the industrial temperature grade ensures reliable start-up in unheated equipment bays.

Communication Protocol Bridge
The EP1C6Q240I7 is well-suited for legacy communication bridging because its 185 user I/O pins allow simultaneous UART, SPI, I2C, parallel FIFO, and address-decoding interfaces. In a typical system, the FPGA sits between an embedded processor and multiple peripherals with different voltage and timing requirements, translating bus protocols without loading the CPU. The 92,160 RAM bits provide small packet buffers or FIFOs for asynchronous clock domains. The fabric's parallel processing prevents protocol bottlenecks when several interfaces must operate concurrently. Because the Q240 package is a through-hole-friendly QFP, it also simplifies prototype debugging and rework during communication-board development. Configuration can be stored in an external EPCS device or transmitted by the host at boot, making field updates manageable.
Recommandé
Video Timing and Display Controller
The EP1C6Q240I7 can generate display timing and frame-buffer control for VGA, LCD, and small-panel systems. Its logic elements implement horizontal/vertical counters, blanking signals, and pixel-clock dividers, while the 92,160 RAM bits act as line buffers or small FIFOs that synchronize incoming pixel data. The 185 I/O pins provide enough outputs for RGB or parallel digital display buses and enough inputs for a camera sensor or host processor interface. In this role, the FPGA adds deterministic timing that a software-only MCU cannot easily provide. The -7 speed grade is typically adequate for VGA and small LVCMOS display interfaces, and the industrial temperature rating permits use in outdoor information displays or machine-vision systems mounted near production heat sources.
Recommandé
Medical Monitoring and Diagnostic Equipment
For medical monitoring and diagnostic equipment, the EP1C6Q240I7 provides a reprogrammable data-acquisition front end that can acquire, filter, and format physiological signals before sending them to a host processor. Its 185 I/O pins connect to multichannel ADCs, isolated interface chips, memory, and user-interface displays. The industrial temperature grade supports equipment designed for clinics and transport environments where ambient temperatures may approach 0°C during storage. The FPGA's parallel architecture permits simultaneous ECG, SpO2, and temperature channel processing without excessive CPU load. Because medical standards often require traceable design changes, FPGA configuration files can be updated and version-controlled more easily than fixed logic. Designers still need to follow applicable medical EMC/ESD standards and choose certified power and isolation components around the FPGA.
Recommandé
Data Acquisition and Instrumentation
In test and measurement systems, the EP1C6Q240I7 is used as a flexible acquisition controller that sequences ADCs, stores samples in RAM, and forwards data over USB, UART, or parallel interfaces. Its 92,160 RAM bits can implement acquisition FIFOs and trigger logic, while the 185 I/O pins connect to many ADC/DAC devices without extra CPLDs. The industrial temperature grade makes the part usable inside benchtop instruments that generate internal heat and in outdoor monitoring equipment. Because FPGA I/O timing is deterministic, sample-valid signals and acquisition windows can be generated with low jitter. Designers should verify that the speed grade -7 meets the required sample-clock rates; for very high-speed digitizers, a faster FPGA family would be necessary. The QFP package is easier to probe during instrument bring-up than a BGA.
Recommandé
FPGA Prototyping and Custom Logic Integration
The EP1C6Q240I7 is an excellent platform for prototyping custom logic because the 240-pin BFQFP can be manually reworked if a prototype has a pin-error, unlike fine-pitch BGA packages. It provides 5,980 logic elements for state machines, address decoders, CRC generators, and peripheral controllers. Because this is an SRAM FPGA, each prototype power-up can load a new bitstream through JTAG in seconds, reducing iteration time. Engineers use it early in product development to verify interface timing before committing to an ASIC. The 185 I/O pins enable connection to multiple debug headers and logic analyzers. The -7 speed grade is adequate for 10-100 MHz class system clocks; when the final design needs more performance, the same Q240 board can sometimes accept the faster -6 speed grade variant for evaluation.

- -7 speed grade with a drop-in Pb-free equivalent (vs EP1C6Q240C8N)

Notes de conception
The EP1C6Q240I7 requires a clean 1.5 V core rail for VCCINT. Use one 10 uF bulk capacitor and a 0.1 uF ceramic capacitor near each VCCINT pin group. I/O bank supply pins should be bypassed according to the configured I/O standard, with typical 0.1 uF per bank. Because this is an SRAM FPGA, inrush current during configuration can be higher than steady-state current; ensure the 1.5 V regulator has enough current headroom and that power sequencing does not hold the FPGA in an undefined I/O state.
The 240-pin BFQFP package has a 0.5 mm or 0.4 mm pitch and requires a well-controlled PCB footprint. Route the high-speed clock and configuration pins with short traces and avoid vias under the fan-out area if possible. Provide a solid ground plane under the FPGA and return vias for each signal layer transition. For legacy compatibility, the Q240 footprint is shared among many EP1C6 derivatives, but always verify pin compatibility with the exact Altera pin file when changing from a commercial-grade to industrial-grade part.
Because the EP1C6Q240I7 is SRAM-based, it must be configured after every power-up. Connect nCONFIG to a controlled pull-up or host GPIO, monitor CONF_DONE, and initialize DCLK only when the FPGA is ready. Do not hold nSTATUS low during normal operation. Also verify whether the assembly must be RoHS compliant: the base EP1C6Q240I7 lacks the N suffix, while EP1C6Q240I7N is the Pb-free version. Legacy non-N parts can contain lead in the solder finish and should not be used in RoHS-oriented production lines.
Informations de conformité
MPN does not contain the Altera N suffix, which is typically used for Pb-free/RoHS-compliant versions. Therefore lead-free/RoHS status cannot be confirmed without the N suffix. AEC-Q100 qualification is not applicable to standard Cyclone FPGAs.
