EP1C6T144ITN 개요

The Altera (Intel) EP1C6T144ITN is a Cyclone-family Field-Programmable Gate Array (FPGA) featuring 5,980 logic elements, 92,160 RAM bits, and 98 user I/Os, packaged in a 144-pin LQFP (T144). It is the industrial-temperature (I) and lead-free (N) speed-grade variant of the EP1C6T144, designed for cost-sensitive, logic-intensive embedded applications.

A Cyclone FPGA is a low-cost SRAM-based programmable logic device from the original Altera Cyclone family (now owned by Intel) that integrates configurable logic blocks (LEs), embedded M4K RAM blocks, and a flexible I/O ring into a single die. Cyclone fits into the programmable-logic hierarchy above simple CPLDs and below high-performance Stratix families, occupying the low-power / low-cost tier of the FPGA taxonomy. The EP1C6 sits at the entry-mid level of Cyclone, offering roughly twice the LE count of the EP1C3 while remaining pin-compatible with the 144-LQFP EP1C3 footprint in many designs, giving engineers a migration path between density points.

Key features include 5,980 LEs, 92,160 embedded RAM bits organized into 20 M4K blocks, two PLLs for clock management, and support for LVDS, LVTTL, SSTL-2, and SSTL-3 I/O standards. The device is fabricated in a 0.13 µm process, operates from a 1.5 V core supply with 3.3 V I/O, and supports JTAG (IEEE 1149.1) configuration via the Altera Quartus II / Quartus Prime design suite. The industrial temperature grade spans -40 °C to +100 °C junction.

Typical applications include industrial control and motor-drive interfaces, low-cost video processing, glue-logic consolidation on legacy PCBs, communication bridging, and educational / development platforms. The 144-LQFP package enables low-cost PCB manufacturing with standard 1.0 mm pitch and eliminates the need for fine-pitch BGA assembly.

When designing with the EP1C6T144ITN, plan for a 1.5 V core rail and 3.3 V I/O rail, place decoupling within 5 mm of each supply pin, and use the JTAG chain for both configuration and in-system debug. Note that the Cyclone family is now in long-term / legacy status, so long-life-cycle programs should confirm availability and consider Cyclone II / Cyclone IV as successors.

🏭

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 EP1C6T144ITN contains 5,980 logic elements (LEs), making it the mid-density point of the Cyclone I family. Per the Altera Cyclone Device Handbook, the 5,980 LEs are supplemented by 92,160 embedded RAM bits organized as 20 M4K blocks and 2 PLLs for clock management, providing a balanced logic/memory ratio for control-plane and glue-logic designs.

Where can I download the EP1C6T144ITN datasheet PDF?

The official datasheet for the EP1C6T144ITN is part of the Altera Cyclone Device Handbook (cyclone-handbook.pdf), available via the Altera / Intel FPGA support documentation portal. The handbook covers DC/AC switching characteristics, I/O standards, configuration modes, and JTAG timing. 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.

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.

Choose the EP1C6T144ITN when you need a Cyclone I FPGA with 5,980 logic elements, 98 user I/Os, and industrial temperature grade (-40 °C to +100 °C junction) in a hand-solderable 144-LQFP package. It is the right part when your design fits within the logic capacity, you need industrial-temperature operation, and you can accept the legacy / last-time-buy supply status. Choose EP1C6T144I7N or EP1C6T144I8N when you need faster speed grades; choose EP1C6T144I8 or EP1C6T144I7 (no 'N') only when you require SnPb finish for non-RoHS processes. Choose EP1C6Q240I7N / EP2C8 / EP4CE6 for new designs that need higher logic capacity, more I/Os, or active lifecycle status.

설계 노트

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.
