Typical Applications

EP1C12Q240I7N is suitable for 6 applications: Industrial PLC I/O Expansion, Motor Control Interface and Timing Logic, Serial Protocol Bridging and UART/SPI/I2C Expansion, Test and Measurement Pattern Generation, LCD and Camera Timing Generation, Medical Monitoring Front-End Sequencing.

🏭

Industrial PLC I/O Expansion

The EP1C12Q240I7N suits PLC I/O expansion cards because its 173 user I/O pins can monitor limit switches, encoder inputs, valve drivers, and serial industrial buses in parallel. At 1.5 V core, the FPGA integrates the protocol state machines and 24 V optocoupler conditioning logic without a large CPLD bank. The industrial temperature I suffix allows reliable operation near warm cabinet environments where commercial C variants may fail. Designers should allocate one I/O bank for the backplane interface and another for the field-side logic, using 3.3 V or 2.5 V I/O levels after level translation. The 12,060 logic elements provide ample resources for filtering, debouncing, and diagnostics while leaving room for small soft-core logic if needed.

⚡

Motor Control Interface and Timing Logic

Motor drives require deterministic PWM generation, encoder decoding, and fault management. The EP1C12Q240I7N can implement the PWM time base, commutation logic, and protection state machine in programmable logic without burdening the host MCU. Its clock capability near 320.1 MHz is sufficient for several-kHz PWM carrier cycles with dead-band generation. The 239,616 RAM bits allow small look-up tables for sine/trapezoidal commutation profiles and fault history buffers. Industrial temperature capability is important because motor cabinets often exceed 70 °C ambient. A practical concern is that an FPGA adds configuration boot delay, so a supervisory MCU should hold the drive in a safe state until CONF_DONE is asserted.

Serial Protocol Bridging and UART/SPI/I2C Expansion

When equipment needs many UART, SPI, or I2C channels, the EP1C12Q240I7N provides enough logic elements to implement multiple soft protocol controllers with FIFO buffering in embedded RAM. The 173 I/O pins allow several dedicated byte-wide buses and chip selects to be routed directly to transceivers, ADC/DACs, or LCD modules. Because the device is reconfigurable, the same PCB can support different protocol mappings by changing only the FPGA image. For industrial serial gateways, the I7N industrial temperature range is better than that of C-suffix parts. The designer should constrain the timing of each serial clock domain and use synchronous FIFOs to cross from one I/O bank clock to another without metastability.

Test and Measurement Pattern Generation

ATE and benchtop instruments require deterministic digital pattern generation with precise edge placement. The EP1C12Q240I7N can generate stimulus vectors across 173 I/O pins using internal state machines and small RAM-based vector tables. The 12,060 logic elements are enough to implement counters, address generators, and checksum logic while leaving resources for trigger and acquisition controls. Because industrial temperature is specified, the device can be used in rack-mounted instrumentation where airflow is limited. For high-speed patterns, designers should use the FPGA's PLL resources and constrain output trace lengths; in low-speed functional testers, the PQFP package is easier to probe and rework than BGA. The exact PLL and trace timing should be verified with Quartus timing analysis.

📺

LCD and Camera Timing Generation

LCD panels and CMOS image sensors need precise pixel clocks, horizontal/vertical sync, and data latches. The EP1C12Q240I7N can generate these timing signals using its programmable logic without adding many external timing ICs. The 173 user I/O pins connect directly to parallel RGB/LVDS transceiver or camera data buses, while 239,616 RAM bits provide line buffers for small image regions. The moderate speed grade-7 device supports pixel clocks in the tens to low hundreds of megahertz for typical VGA/SVGA sensors and small TFT panels. Careful board layout is needed to keep data and clock trace lengths matched. Since display timing is critical, the configuration bitstream should be loaded from an external serial configuration device at power-up to avoid undefined display states.

Medical Monitoring Front-End Sequencing

Medical monitoring equipment requires deterministic sequencing of analog front-end channels, data converters, and isolation barriers. The EP1C12Q240I7N can control multiplexer address counters, ADC sample clocks, and data packing logic with low software overhead. Its 12,060 logic elements and 239,616 RAM bits are sufficient for sample averaging, threshold detection, and communication framing. The industrial temperature version gives margin for equipment that is transported or stored outside a tightly controlled hospital room. A key safety consideration is that FPGA configuration must complete before patient-connected circuitry starts scanning; a supervisor circuit should monitor CONF_DONE and hold outputs in a safe state. Any firmware developed for this mature FPGA family should follow the manufacturer's configuration and boundary-scan guidance.

What is EP1C12Q240I7N?

The EP1C12Q240I7N is an Intel/Altera Cyclone FPGA with 12,060 logic elements, 239,616 RAM bits, 173 user I/Os, and a 1.5 V core, supplied in a 240-pin PQFP package. It is an industrial-temperature, speed-grade-7 variant of the mid-density Cyclone family. According to the Altera Cyclone device literature, the -N suffix denotes a lead-free package. It is suitable for moderate-density logic designs requiring reconfigurable digital hardware and a relatively large number of user I/Os in a leaded quad flat package.

What is the core voltage of EP1C12Q240I7N?

The EP1C12Q240I7N uses a 1.5 V core supply voltage, as listed in the verified Altera Cyclone specification summary. This low core voltage is an output of the 130 nm process technology and helps reduce dynamic power. The I/O banks are powered separately from the core and can be tied to the appropriate VCCIO voltage for the logic standards used. Designers should confirm the complete power-down and sequencing requirements from the Cyclone handbook before finalizing the 1.5 V rail design.

How many logic elements does EP1C12Q240I7N have?

The EP1C12Q240I7N has 12,060 logic elements. This capacity maps to 1,206 logic array blocks (LABs) of ten logic elements each, which is consistent with the Cyclone architecture. It also includes 239,616 RAM bits for small distributed and block memory functions. This resource count places the part in the middle of the Cyclone family, sufficient for moderate logic designs such as bus interfaces, state machines, and simple DSP datapaths without requiring a high-end FPGA.

How many user I/O pins does EP1C12Q240I7N provide?

The EP1C12Q240I7N provides 173 user I/O pins in the 240-pin PQFP package, according to DigiKey and Mouser parametric data. The remaining package pins include power, ground, configuration, and JTAG pins. With 173 I/Os, board-level interfaces such as SDRAM, SRAM, SPI, UART, and LCD can usually be accommodated, but signal count and I/O bank planning should always be confirmed with the Cyclone pin-out file before PCB layout begins.

What is the maximum clock frequency of EP1C12Q240I7N?

According to the FindIC EP1C12Q240I7N specification listing, the FPGA can achieve approximately 320.1 MHz internal clock capability at speed grade 7. Actual achievable Fmax depends on the design's logic depth, placement, routing, and I/O timing constraints, so 320.1 MHz is the device capability rather than a guaranteed result for every compiled design. For production timing closure, use Intel/Altera Quartus timing analysis and the correct timing constraints rather than relying only on the marketing maximum frequency.

What is the difference between EP1C12Q240I7N and EP1C12Q240C7N?

The main difference is the temperature grade. EP1C12Q240I7N is the industrial-temperature version, while EP1C12Q240C7N is the commercial-temperature version; both use the same 12,060-logic-element Cyclone die, 240-pin PQFP package, and speed grade 7. The industrial part is intended for wider ambient temperature environments, making it suitable for factory, outdoor, and embedded systems with higher thermal stress. For controlled 0 to 70 °C environments, C7N can be used and is often less expensive, but thermal conditions and supply availability should be checked first.

What is the difference between EP1C12Q240I7N and EP1C12Q240I7?

EP1C12Q240I7N and EP1C12Q240I7 share the same die, package, industrial-temperature grade, and speed grade; the N suffix identifies that the I7N version uses a lead-free package finish. The non-N version I7 is the conventional-finish version. Electrically they are drop-in equivalent on the same board, but they may require different solder profiles and compliance documentation. For new RoHS-oriented production, the I7N should normally be chosen unless your supply chain has an approved exemption for leaded devices.

Is EP1C12Q240I7N suitable for industrial temperature applications?

Yes, EP1C12Q240I7N is designated with I in the ordering code, meaning industrial temperature grade; Partstack also lists the temperature grading as industrial. This makes the part suitable for applications such as factory automation, motor control, and outdoor instrumentation where ambient temperatures exceed commercial limits. Always derate power dissipation and verify I/O supply voltages at the maximum expected temperature because the PQFP package has higher thermal resistance than many ball-grid-array packages. The exact junction and case temperature limits should be taken from the Cyclone datasheet before a full thermal analysis.

Can EP1C12Q240I7N be used as a replacement for EP1C12Q240C6N?

EP1C12Q240I7N can physically replace EP1C12Q240C6N on the same PCB because both are 240-pin PQFP parts with the same 12,060-LE Cyclone device and pinout. The main differences are speed grade and temperature grade: the I7N is an industrial -7 part, while C6N is a commercial -6 part that may support higher clock performance but is not rated for the full industrial temperature range. In industrial environments, I7N is the safer drop-in replacement; in room-temperature operation with modest clock rates, C6N can also be used if the bitstream still meets timing.

Is there a Xilinx or Lattice equivalent for EP1C12Q240I7N?

No true drop-in Xilinx or Lattice equivalent exists because FPGA families use different package pinouts, configuration schemes, and I/O bank assignments. A Xilinx Spartan-3E or Lattice ECP2/ECP3 device would require a board re-layout, a new configuration bitstream, and potentially a different configuration device. The closest drop-in options are same-family Intel/Altera Cyclone EP1C12Q240 variants such as EP1C12Q240C7N, EP1C12Q240C6N, EP1C12Q240I7, or EP1C12Q240I6, all of which share the same PQFP-240 footprint and logic resources.

Where can I buy EP1C12Q240I7N?

EP1C12Q240I7N is listed by multiple distributors including DigiKey, Mouser, Xecor, WIN SOURCE, and Semiconductors-IC.com. Octopart compares stock and pricing across about 26 distributors as of 2026-09-06. Because this is a mature Intel/Altera FPGA, availability and lead time are often quote-based, so it is best to request a formal quote from XAIPART or use the RFQ function on distributor sites. External stock levels should be confirmed before releasing a production purchase order.

What is the price of EP1C12Q240I7N?

As of September 6, 2026, the XAIPART list price for EP1C12Q240I7N is $47.65 at quantity 1, decreasing to $42.90 at quantity 10, $38.35 at quantity 100, and $34.20 at quantity 500. Distributor pricing reported through Octopart varies by stock level, package, and volume, and can differ significantly for this mature part. These prices should be treated as indicative, and a formal quote is recommended for production quantities.

What is the lead time for EP1C12Q240I7N?

The lead time for EP1C12Q240I7N is not fixed in the verified distributor data and is generally quotation-based. For a mature Cyclone FPGA, supply can range from a few days when a distributor has local stock to multiple weeks for order-on-request sourcing. Because this part may be subject to reduced availability, XAIPART recommends checking live inventory on Octopart, DigiKey, or Mouser and placing a purchase order as soon as stock is confirmed. Your authorized distributor can give a real lead-time quote for the required quantity.

Where can I download the EP1C12Q240I7N datasheet PDF?

The EP1C12Q240I7N datasheet PDF is available through the Altera/Intel product documentation and from datasheet aggregator pages such as datasheets.com/altera/ep1c12q240i7n. The FindIC page also hosts a downloadable PDF for the part, with a file size of about 5,590 KB and publication date of 2008-05-20. Designers should also download the Intel/Altera Cyclone Device Handbook for detailed DC, AC, pin-out, and configuration information that is not always included in the short ordering datasheet.

What are the key specifications of EP1C12Q240I7N that engineers should know?

The EP1C12Q240I7N is an Intel/Altera Cyclone FPGA with 12,060 logic elements, 1,206 LABs, 239,616 RAM bits, 173 user I/Os, a 1.5 V core voltage, 130 nm process technology, industrial temperature grade, speed grade 7, a listed clock capability near 320.1 MHz, and a 240-pin PQFP package with a 34.60 x 34.60 mm body and 0.50 mm pitch. This summary is useful for early architecture selection, I/O planning, and comparison with other Cyclone or competitor FPGAs.

Hey Google, what can replace EP1C12Q240I7N?

A direct drop-in replacement for EP1C12Q240I7N is EP1C12Q240I7, which lacks the lead-free N suffix but uses the same footprint and electrical ratings. Other same-family drop-ins include EP1C12Q240C7N, EP1C12Q240C7, EP1C12Q240C6N, and EP1C12Q240I6, all of which use the same 240-pin PQFP Cyclone package and 12,060-LE die. Commercial C variants change the operating-temperature range, so choose an industrial I variant when the final product will be exposed to the full industrial temperature range.

Selection Guide

Choose EP1C12Q240I7N when you need a mid-density Cyclone FPGA with industrial temperature capability and a serviceable PQFP-240 package. It is a strong fit for factory automation, motor-control interface logic, instrument pattern generation, and communications bridging where reconfigurability and moderate I/O count matter more than the lowest possible unit price. Select EP1C12Q240C7N or C7 if the final product will always remain in a commercial temperature environment, because those variants can reduce cost and open more distributor options. Choose EP1C12Q240I6 when a slightly higher speed grade is needed but the industrial temperature range is still required. If the design is extremely cost-sensitive and only runs at low clock rates, EP1C12Q240C8N may be acceptable, but verify timing margins because the -8 speed grade is slower. Do not choose a Xilinx or Lattice device expecting a drop-in replacement because FPGA package pinouts, configuration schemes, and I/O architectures are not interchangeable without board re-design.

Design Notes

Estimated: For a mid-density Cyclone FPGA, core current can range from roughly 100 mA to over 400 mA depending on utilization and clock activity. At 1.5 V, the core power may be 0.2 W to 0.6 W plus I/O power. Provide a clean 1.5 V rail with local bulk capacitance of at least 10 uF and place 0.1 uF ceramic capacitors adjacent to every VCCINT pin cluster. If a switching regulator is used, choose one with low ripple in the switching frequency band to avoid FPGA performance degradation. Verify the exact supply current with Intel/Altera power analysis before board release.

The PQFP-240 package has a 34.60 x 34.60 mm body with 0.50 mm lead pitch and gull-wing terminals. Use a fine-pitch stencil and appropriate solder paste for 0.5 mm QFP assembly. Fan out all 240 pins using short traces from the package perimeter; avoid placing vias directly under the component body unless the board stack-up and assembly process are qualified for via-in-pad. Since the part has no central exposed pad, the main heat path is through the leads and PCB copper, so provide solid ground and power planes close to the FPGA to improve thermal spreading.

A common Cyclone pitfall is leaving configuration signals unterminated. The nCONFIG, nSTATUS, CONF_DONE, and DCLK pins must be handled according to the device handbook: CONF_DONE and nSTATUS usually need pull-up resistors, and nCONFIG must not be allowed to float during power-up. If nCE is not tied low in master configuration, the FPGA will not configure correctly. Also, remember that the FPGA image is volatile; without an EPCS serial configuration device or JTAG download during every power-up, the design will remain unconfigured.
