Typical Applications
EP1C6Q240I7 is suitable for 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.
Recommended
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.
Recommended
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.
Recommended
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.
Recommended
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.
Recommended
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.

Key Differentiators
- Industrial temperature range in the 240-pin Q240 package (vs EP1C6Q240C7N)
- -7 speed grade with a drop-in Pb-free equivalent (vs EP1C6Q240C8N)
- Legacy 240-BFQFP package is easier to route and rework than BGA Cyclone variants (vs EP1C6F256I7N)
Design Notes
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.
Compliance Information
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.
