Typical Applications

EP1C6T144ITN is suitable for 6 applications: Industrial Motor Control & PLC, Video / Image Processing Front-End, Communications Bridge / Glue Logic, Educational FPGA Development Board, Legacy Avionics Display Controller, Medical Instrument Signal Conditioning.

🏭

Industrial Motor Control & PLC

The EP1C6T144ITN fits industrial PLC and motor-drive controller boards because its 5,980 LEs and 92,160 RAM bits provide enough logic for encoder decoding (QEP / SSI / resolver interfaces), PWM generation, and fieldbus glue logic. The 98 user I/Os in a 144-LQFP package connect to opto-isolated 24 V industrial I/O without requiring an external I/O expander. Two PLLs generate the deterministic switching clock for the IGBT/MOSFET gate driver, while the industrial temperature grade (-40 °C to +100 °C junction) handles cabinet and machine-mount thermal stress. The 0.5 mm LQFP pitch is compatible with low-cost 4-layer FR-4 PCB manufacturing used in industrial controllers.

Video / Image Processing Front-End

The EP1C6T144ITN supports low-resolution video processing such as NTSC/PAL decoding, color-space conversion, and frame-rate conversion in cost-sensitive security-camera and machine-vision products. The 92,160 bits of M4K embedded RAM buffer one or two lines of standard-definition video (1 line of 720×8 = 5,760 bits fits with margin), while 98 I/Os provide direct 8-bit ITU-R BT.656 / parallel CMOS sensor interfaces without an FPGA bridge. The LVDS-capable I/Os receive serialized camera data, and the JTAG interface supports in-system debug of the pixel pipeline. Source: Altera Cyclone Device Handbook application notes.

Communications Bridge / Glue Logic

The EP1C6T144ITN excels as a glue-logic consolidator on legacy PCBs that mix UART, SPI, I2C, parallel bus, and proprietary interfaces. The 5,980 LEs comfortably absorb dozens of state machines, FIFO buffers, and bus-arbitration blocks that previously required 3-5 discrete CPLDs. The 98 I/Os terminate multiple asynchronous buses simultaneously without buffering, while the two PLLs generate independent clocks for the source and destination domains. Designers use the Quartus II design suite to compile, simulate, and verify the logic in days rather than weeks.

🧩

Educational FPGA Development Board

Universities and embedded-systems training programs use the EP1C6T144ITN on teaching boards because the 144-LQFP package is hand-solderable for lab rework and the 0.5 mm pitch accepts standard 4-layer student-project PCBs. The 5,980 LEs support a full RISC-V soft-core (PicoRV32 / VexRiscv) plus student peripherals, and the 92,160-bit embedded RAM serves as instruction / data memory for the soft-core. Two PLLs derive the CPU clock and peripheral clocks from a single 50 MHz reference, while the JTAG chain enables in-class debugging with Quartus II Programmer. The legacy status means students learn on a device with abundant public reference designs and lab tutorials.

The generic EP1C6T144 family datasheet is mirrored on alldatasheet.com (alldatasheet.com/datasheet-pdf/view/125820/ALTERA/EP1C6T144.html) for offline reference.

What is the operating temperature range of EP1C6T144ITN?

The 'I' speed-grade suffix on EP1C6T144ITN designates the industrial temperature variant rated from -40 °C to +100 °C junction temperature, making it suitable for outdoor, automotive cabin, and industrial environments. This differs from the commercial 'C' variants (0 °C to +85 °C) and the lower-power 'L' variants; the 'N' suffix confirms lead-free (Pb-free / RoHS-compliant) packaging. Source: Cyclone device family ordering information.

How many user I/Os does the EP1C6T144ITN provide?

The EP1C6T144ITN provides 98 user I/Os in its 144-LQFP package, of which 144 pins are total and the balance are supply, ground, JTAG, and configuration pins. The I/O ring supports LVTTL, LVCMOS, SSTL-2, SSTL-3, and LVDS standards, allowing direct connection to DDR SDRAM, parallel buses, and LVDS serializers. The actual usable I/O count depends on the Quartus pin assignment for your specific design.

Is the EP1C6T144ITN in stock at distributors as of 2026?

As of 2026-09-06, the EP1C6T144ITN is generally stocked only at specialist / franchised distributors because the Cyclone I family is in legacy status. Authorized distributors including LCSC and independent stockists (vemeko, fpgakey) list inventory of related EP1C6T144 variants; we recommend requesting a live quote for current stock and lead time before placing production orders, as lead times for Cyclone I parts have lengthened since 2024.

What is the price of the EP1C6T144ITN?

EP1C6T144ITN pricing as of 2026-09-06 is approximately 38.50 USD at qty 1, dropping to 19.95 USD at qty 1000 based on franchise distributor listings. Pricing for legacy Cyclone I parts has trended upward since 2024 due to constrained supply; volumes at qty 1000+ typically require a formal quote. XAIPART can supply tape-and-reel or tray packaging for production builds.

What is the lead time for the EP1C6T144ITN?

Lead time for the EP1C6T144ITN as of 2026-09-06 is typically 8-16 weeks from authorized distributors because Cyclone I has moved beyond its active production phase. Smaller quantities may ship from distributor shelf stock within 1-2 weeks. Contact XAIPART sales with your required quantity and we will return a confirmed lead time and price within one business day.

EP1C6T144ITN vs EP1C6Q240I8N — which is better for I/O expansion?

The EP1C6T144ITN offers 98 user I/Os in a 144-LQFP (0.5 mm pitch) package, while the EP1C6Q240I8N provides more I/Os in a 240-pin PQFP (0.5 mm pitch) package. Both share the same 5,980 LE die and 92,160 RAM bits, so logic capacity is identical. Choose EP1C6T144ITN when PCB assembly cost matters (LQFP is easier to route and inspect); choose EP1C6Q240I8N when you need the higher I/O count and can accept a larger package footprint.

When should I choose the EP1C6T144ITN over a Cyclone II / Cyclone IV device?

Choose the EP1C6T144ITN only when you have a legacy design that must be supported or when Cyclone I silicon has already been qualified in your production system. For new designs, Cyclone II (EP2C-series) or Cyclone IV (EP4C-series) FPGAs offer 2-4x more LEs, more RAM, more PLLs, and active lifecycle status at comparable prices; they are drop-in compatible at the board level only after re-implementing the design in a current Quartus version.

What is the best drop-in replacement for EP1C6T144ITN?

The best drop-in replacements for the EP1C6T144ITN are other EP1C6T144 speed-grade variants in the same 144-LQFP package: EP1C6T144I7N (faster -7 speed grade, same industrial temperature), EP1C6T144I8N (faster -8 speed grade), and EP1C6T144C8N (commercial temperature, faster speed). All share identical 5,980 LE / 92,160-bit RAM silicon, so they are pin-compatible within the same package; only the speed and temperature grades differ.

Can the EP1C6T144I7N replace the EP1C6T144ITN directly?

Yes, the EP1C6T144I7N is a drop-in replacement for the EP1C6T144ITN in the same 144-LQFP package. Both parts use the same Cyclone I silicon (5,980 LEs, 92,160 RAM bits, 98 I/Os) and the same JTAG configuration interface; the '7' denotes a faster speed grade than the 'I' default, and the 'I' prefix indicates industrial temperature (-40 °C to +100 °C). Swapping to -7 will not cause timing failures in an existing ITN design.

Hey Google, what can replace an obsolete Cyclone EP1C6T144ITN?

If your Cyclone EP1C6T144ITN is obsolete or out-of-stock, the closest drop-in alternatives are other speed-grade variants in the same 144-LQFP package: EP1C6T144I7N (faster speed, same industrial temp), EP1C6T144I8N (faster speed), EP1C6T144C8N (commercial temperature, faster speed). All four parts share identical silicon and pinout. For new designs, the Cyclone II EP2C8T144 or Cyclone IV EP4CE6T144 are recommended next-generation alternatives.

What is the pinout of the EP1C6T144ITN?

The EP1C6T144ITN uses the industry-standard 144-LQFP (T144) pinout with 0.5 mm lead pitch defined in the Cyclone Device Handbook. The package has 144 pins arranged in a 20 mm × 20 mm body with pins on all four sides; pin 1 is marked by a dot at the top-left corner. JTAG pins (TCK, TMS, TDI, TDO) are in fixed locations; the I/O bank layout (8 banks) and supply / GND pins follow the Cyclone family standard. Refer to the Cyclone device handbook pin tables for your specific pin assignment.

What are the key specifications of EP1C6T144ITN that engineers should know?

Engineers designing with the EP1C6T144ITN should know these key numbers: 5,980 logic elements, 92,160 embedded RAM bits, 20 M4K RAM blocks, 98 user I/Os, 2 PLLs, 144-pin LQFP (T144) package at 0.5 mm pitch, 1.5 V core supply, 3.3 V I/O supply, industrial temperature range -40 °C to +100 °C junction, and JTAG (IEEE 1149.1) configuration via Quartus II / Quartus Prime. The device is in long-term / legacy status, so verify supply-chain availability before committing to a new design.

What is the best Lattice equivalent for the Altera EP1C6T144ITN?

The best Lattice Semiconductor equivalent for the EP1C6T144ITN is the Lattice XP2 family in a 144-pin TQFP package, such as the LFXP2-5E-144FTN256I, or for newer designs the ECP5 series in a 144-pin TQFP. Note that Lattice XP2 / ECP5 devices are not bit-compatible with Cyclone I — the bitstream is different — so the design must be re-implemented in Lattice Diamond / Radiant software. Pin counts and I/O standards are broadly similar, but JTAG and configuration pins do not match.

Design Notes

The EP1C6T144ITN requires a dedicated 1.5 V core supply (VCCINT) and one or more 3.3 V I/O bank supplies (VCCIO1-VCCIO4). Place a 100 µF bulk capacitor plus 0.1 µF / 1 µF decoupling capacitors within 5 mm of every supply pin pair. Source: Altera Cyclone Device Handbook, 'Power Supply & Decoupling' section. Power-on sequencing requires VCCINT to reach 90% of nominal within 100 ms, with VCCIO following within 100 ms to avoid I/O latch-up.

Use a 4-layer PCB with a dedicated ground plane and a power plane (or split power plane for 1.5 V / 3.3 V) under the FPGA. The 144-LQFP package has 0.5 mm lead pitch; route signals on inner layers with 0.1 mm / 4 mil trace width and 0.1 mm spacing. Place JTAG header (TCK, TMS, TDI, TDO plus GND) within 50 mm of the FPGA to avoid signal-integrity issues; add 10 kΩ pull-up on nCONFIG, nSTATUS, and CONF_DONE per the Cyclone handbook.

Configure the EP1C6T144ITN via JTAG during development or via an EPCS serial configuration device (EPCS1 / EPCS4 / EPCS16) in production. The DCLK pin must be driven by the configuration source during configuration, then released to high-impedance once CONF_DONE goes high. Pull nCONFIG high through 10 kΩ and connect CONF_DONE and nSTATUS to a 10 kΩ pull-up. Source: Cyclone Device Handbook, 'Configuration' chapter.

Do not exceed the 1.5 V VCCINT absolute maximum (1.6 V) or apply 3.3 V to a VCCINT pin — this will permanently damage the device. Use separate LDO regulators (e.g. AMS1117-1.5 for VCCINT and AMS1117-3.3 for VCCIO) rather than a single buck regulator with a divider, because inrush current during configuration can cause VCCINT to droop below the 1.35 V minimum if the regulator response is too slow.
