EP1C6T144C7 概要

The Altera (Intel) EP1C6T144C7 is a Cyclone family Field-Programmable Gate Array (FPGA) integrating 5,980 logic elements, 92,160 RAM bits, and 98 user I/O pins in a 144-pin TQFP/LQFP package. It is fabricated on a 130 nm process, operates from a 1.5 V core supply with 3.3 V I/O tolerance, and supports up to 320 MHz internal operation. The device belongs to the original Cyclone generation that introduced a low-cost FPGA architecture for high-volume applications.

A Field-Programmable Gate Array (FPGA) is a programmable logic device containing an array of configurable logic blocks (CLBs) interconnected via a programmable routing fabric. The Cyclone family sits within Altera's mid-density product hierarchy, between the smaller Cyclone II entry parts and the higher-end Stratix devices. FPGAs enable designers to implement custom digital logic, glue logic, and parallel processing functions that can be reconfigured after PCB assembly, making them distinct from fixed-function ASICs and from CPLDs that target simpler glue-logic tasks.

Key features include 5,980 logic elements distributed across 598 logic array blocks (LABs), 92,160 bits of embedded RAM, two phase-locked loops (PLLs) for clock management, and 98 user I/O pins supporting LVTTL, LVCMOS, SSTL, and differential I/O standards. The device integrates dedicated 18 x 18 hardware multipliers that support DSP functions such as FIR filters and video processing without consuming general-purpose logic.

The Cyclone architecture combines a four-input look-up-table logic element with embedded memory blocks, multiplier blocks, and PLL clock networks. The 130 nm process node balances cost and performance, with the TQFP-144 package providing a low-cost plastic platform suitable for prototype and moderate-volume production where BGA packages would be uneconomical.

Typical applications include industrial control, video processing, consumer electronics, communications glue logic, and educational prototyping boards. The combination of moderate logic capacity, embedded multipliers, and a low-cost TQFP package makes the EP1C6T144C7 particularly suitable for designs transitioning from discrete logic or CPLD-based implementations.

When designing with this device, ensure the Quartus II design software is used (legacy versions support the original Cyclone family), and verify that the 1.5 V core supply is well-decoupled with bulk and high-frequency ceramic capacitors placed close to the VCCINT pins.

This page synthesizes distributor pricing, same-family drop-in alternatives, and design notes that complement the original Altera datasheet for engineers maintaining legacy Cyclone I designs.

主な用途

EP1C6T144C7 の用途: 7 件s: Industrial Control and Factory Automation, Video Processing and Image Pipeline, Communications Glue Logic and Protocol Bridging, Educational FPGA Prototyping and Development Boards, Consumer Audio and Display Processing, Test and Measurement Instrumentation Front-End, Legacy Avionics and Aerospace Subsystems.

🏭

Industrial Control and Factory Automation

The EP1C6T144C7 is well suited to industrial control PLC and motion controller designs because its 5,980 logic elements plus 20 dedicated 18x18 hardware multipliers support encoder decoding, PID control loops, and stepper/servo drive interfaces within a single device. The 92,160 bits of embedded RAM buffer data tables and lookup waveforms without external SRAM. The 144-LQFP package withstands industrial thermal and mechanical stress while supporting hand-rework during prototyping. In a typical motion controller, the FPGA sits between the microcontroller and the power-stage gate drivers, offloading deterministic I/O scanning at microsecond rates. Compared with a CPLD-only approach, the EP1C6 adds multiplier-rich DSP capability for S-curve profiling and FFT vibration analysis on the same board.

📺

Video Processing and Image Pipeline

The EP1C6T144C7 fits entry-level video processing pipelines such as camera-link frame grabbers, NTSC/PAL video overlay generators, and VGA-format scalers. The 20 hardware 18x18 multipliers implement 2D FIR filters and color-space conversion (RGB to YCbCr) at real-time pixel rates, while the 92 Kbit embedded RAM serves as line buffers and lookup tables for gamma correction. The 98 user I/Os accommodate parallel video buses, sync signals, and I2C/SPI control channels. With a C7 speed grade the device sustains pixel clocks up to 320 MHz internal, sufficient for SXGA resolution timing. The 144-LQFP package simplifies thermal management because typical video designs run at moderate toggle rates with predictable junction temperatures.

🌐

Communications Glue Logic and Protocol Bridging

The EP1C6T144C7 is widely deployed as a glue-logic bridge between ASSP devices that lack compatible interfaces - for example, translating between SPI, I2S, UART, and parallel bus protocols in telecom and networking equipment. The 5,980 logic elements and 98 user I/Os easily handle multi-channel protocol converters with full state-machine and FIFO buffering. The two on-chip PLLs generate the multiple clock domains required when bridging asynchronous links at different rates. Compared with discrete 74-series logic, the FPGA replaces dozens of packages with a single 144-LQFP, reducing PCB area and improving testability. Cyclone family devices remain a popular choice for legacy telecom line cards where long-life-cycle component supply is essential.

🧩

Educational FPGA Prototyping and Development Boards

Universities and hobbyists use the EP1C6T144C7 in teaching labs because the 144-LQFP package supports 0.5 mm-pitch hand-soldering for student projects and breakout boards. The moderate 5,980-logic-element capacity is large enough to host classroom projects such as CPU cores (MIPS, RISC-V), custom peripherals, and signal-processing labs without overwhelming beginners. The 98 user I/Os connect to breadboard-compatible headers, LEDs, and switches, while the embedded 18x18 multipliers enable introductory DSP labs. The mature Quartus II 13.0sp1 toolchain provides extensive teaching materials and reference designs. The plastic TQFP package is also more forgiving than fine-pitch BGA for student assembly errors.

🎧

Consumer Audio and Display Processing

The EP1C6T144C7 handles consumer audio processing tasks such as multi-channel digital audio routing, sample-rate conversion glue, and HDMI/DisplayPort sideband-channel handling in mid-range A/V receivers and set-top boxes. The hardware multipliers accelerate audio DSP algorithms including parametric EQ and bass management, while the 92 Kbit RAM implements audio delay lines and FIFO buffers. The 98 user I/Os accommodate multiple I2S, SPDIF, and parallel display interfaces. The 1.5 V core and 3.3 V-tolerant I/Os are well suited to consumer 3.3 V power rails, simplifying the bill of materials. Cost-conscious consumer designs benefit from the Cyclone family's low unit pricing at moderate volumes.

🔧

Test and Measurement Instrumentation Front-End

The EP1C6T144C7 is used in benchtop test equipment such as logic analyzers, protocol exercisers, and programmable stimulus generators where its hardware multipliers implement waveform arithmetic and its 98 user I/Os drive or sample many channels in parallel. The two PLLs generate tunable clock sources for frequency-counter blocks, and the embedded RAM captures trace buffers of thousands of samples per channel. The 144-LQFP package simplifies prototype rework when front-end designs iterate. Engineers value the Cyclone family's mature IP library and the broad availability of reference designs for IEEE-488, SPI, I2C, and UART protocol decoding. Combined with its long-term supply status, the EP1C6T144C7 remains a reliable choice for instrument manufacturers.

✈️

Legacy Avionics and Aerospace Subsystems

Avionics subsystems with DO-254 design heritage requirements still qualify the EP1C6T144C7 for retrofit and line-replaceable unit production where re-certification of newer FPGAs would be costly. The 5,980 logic elements provide sufficient capacity for interface management, ARINC 429/653 bus bridging, and discrete-signal conditioning in flight-control adjuncts. The 144-LQFP package withstands the mechanical and thermal stress of aerospace environments while supporting conventional board-level assembly. Long-term supply programs and avionics-grade component traceability favor mature Cyclone I parts over newer families with shorter production histories. Designers must verify continued compliance with the latest avionics component obsolescence standards.

What is the logic capacity of the EP1C6T144C7?
The EP1C6T144C7 contains 5,980 logic elements organized in 598 logic array blocks (LABs), with 92,160 bits of embedded RAM and 20 dedicated 18x18 hardware multipliers. According to the Altera Cyclone family datasheet, this positions the EP1C6 in the mid-density tier of the original Cyclone product line, suitable for designs requiring moderate DSP and logic capacity at low cost.
What package does the EP1C6T144C7 use?
The EP1C6T144C7 ships in a 144-pin Low-profile Quad Flat Pack (LQFP/TQFP) measuring 22 x 22 mm with a 0.5 mm pin pitch. The plastic TQFP package is surface-mountable and supports hand-soldering for prototype work, unlike fine-pitch BGAs which require X-ray inspection of solder joints.
Is the EP1C6T144C7 still in production?
The EP1C6T144C7 is in obsolete/legacy lifecycle status. The original Cyclone family was superseded by Cyclone II, III, IV, and later families. Per distributor listings on DigiKey, the part is still available from authorized stock but is not recommended for new designs; consider EP1C6Q240C6 or EP1C6F256C6 same-family variants, or migrate to Cyclone IV E for new projects.

The part remains available despite obsolete status because of long-life-cycle industrial and aerospace programs.
EP1C6T144C7 vs EP1C6T144C6 - what is the difference?
The EP1C6T144C7 and EP1C6T144C6 differ only in the speed grade: the C7 device is rated to 320 MHz internal operation while the C6 device is rated to lower internal frequencies. Both share the same 5,980 logic elements, 92,160 RAM bits, 98 user I/Os, and identical 144-LQFP package, making them drop-in compatible when timing closure is achievable at the slower speed grade.
EP1C6T144C7 vs EP1C6T144C8 - which speed grade should I choose?
The C8 speed grade is faster than C7, with higher internal Fmax. For most designs the C7 is sufficient; choose C8 only if timing analysis shows the C7 cannot meet critical path requirements. Both share the same 144-LQFP package, but C8 typically commands a price premium of 20-30 percent over C7.
What is the best drop-in replacement for EP1C6T144C7?
The best drop-in replacement for the EP1C6T144C7 in the same 144-LQFP package is the EP1C6T144C7N (Pb-free version) or EP1C6T144C6 (slower speed grade). Both share identical pinout and logic resources, so existing PCB designs require no changes. For designs that can tolerate a footprint change, the EP1C6Q240C6 in PQFP-240 provides additional I/O.
What is the equivalent Altera/Intel part for EP1C6T144C7?
Intel (which acquired Altera) still manufactures the EP1C6T144C7 as a mature product for legacy customers. Within the same Cyclone I family, drop-in equivalents include EP1C6T144C6 (slower), EP1C6T144C7N (Pb-free), and EP1C6T144C8 (faster). Cross-brand equivalents from Xilinx such as the Spartan-3 XC3S200 in similar packages are not pin-compatible and require PCB redesign.
Where to download the EP1C6T144C7 datasheet PDF?
The EP1C6T144C7 datasheet can be downloaded from Alldatasheet.com (file size 1 MB, 94 pages) or from the official Altera/Intel documentation archive. The Cyclone family datasheet covers all density and speed-grade variants. According to the FindIC record, the document was originally published on 2008-05-20 by Altera Corporation.
Where can I find the EP1C6T144C7 pinout?
The pinout for the EP1C6T144C7 is documented in the Cyclone family datasheet, available as a PDF download from Alldatasheet.com. The 144-LQFP package has pins arranged in a 0.5 mm pitch quad configuration around the 22 x 22 mm body. We have summarized all 144 pins with names and descriptions in the pinout section of this product page for quick reference.
What is the operating voltage of EP1C6T144C7?
The EP1C6T144C7 operates from a 1.5 V core supply (VCCINT) with I/O banks that are 3.3 V tolerant. According to the Cyclone family datasheet, separate VCCIO pins configure I/O bank voltage (1.5 V, 1.8 V, 2.5 V, or 3.3 V) to interface with mixed-voltage logic. Proper power sequencing is recommended: VCCINT should ramp before or simultaneously with VCCIO.
Is the EP1C6T144C7 RoHS compliant?
RoHS compliance status for the EP1C6T144C7 varies by suffix: the standard EP1C6T144C7 is typically non-RoHS (contains lead), while the EP1C6T144C7N suffix denotes a Pb-free version. According to the JAK Electronics comparison record, both parts share identical logic and pinout but differ in terminal finish and RoHS classification. Always check the specific datasheet version for the suffix you are ordering.
What design software supports the EP1C6T144C7?
The EP1C6T144C7 is supported by Altera Quartus II design software versions up to 13.0sp1, which is the final release with original Cyclone family support. Modern Intel Quartus Prime does not include the original Cyclone I device library; users must maintain Quartus II 13.0sp1 or migrate designs to Cyclone IV E (EP4CE6) which is supported by current Quartus Prime editions.

選定ガイド

Choose the EP1C6T144C7 for new designs only if you require continued availability of a proven Cyclone I part with mature Quartus II toolchain support and you specifically need the C7 speed grade. For most new designs, migrate to Cyclone IV E (EP4CE6E22C8N) which is actively supported by current Quartus Prime. Among same-package drop-in alternatives: choose EP1C6T144C7N if your application requires RoHS compliance; choose EP1C6T144I7N if your design must operate across -40C to +100C industrial temperature range; choose EP1C6T144C6 if timing closure is achievable at lower speed grade for cost savings; choose EP1C6T144C8N only when critical paths exceed C7 capability. All seven drop-in alternatives listed share the 144-LQFP footprint, allowing zero-cost PCB reuse across speed grades, temp ranges, and compliance variants.

主な差別化要因

  • Mid-density Cyclone I original with 5,980 LEs in low-cost 144-LQFP (vs EP1C3T144C8 (smaller Cyclone I, 2,910 LEs))
  • Industrial-temperature variant available for harsh environments (vs EP1C6T144C7 (commercial 0C to +85C))
  • Pb-free terminal-finish option for modern compliance programs (vs EP1C6T144C7 (SnPb finish, non-RoHS))

設計ノート

The EP1C6T144C7 requires separate VCCINT (1.5 V core) and VCCIO (per-bank I/O supply at 1.5/1.8/2.5/3.3 V) rails. Recommended decoupling: one 100 uF bulk tantalum plus one 10 uF ceramic per rail, with 0.1 uF and 0.01 uF high-frequency ceramics placed within 5 mm of each VCCINT and VCCIO pin pair. Power sequencing: VCCINT must ramp to 90 percent of nominal before or simultaneously with VCCIO to prevent I/O latch-up. Estimated: total inrush current during configuration is approximately 200-400 mA peak; the bulk capacitor must sustain this until the on-die LDO stabilizes.

The 144-LQFP at 0.5 mm pin pitch requires a 4-layer PCB with continuous power and ground planes under the device to control return-current paths. All VCCINT and VCCIO pins must be tied to their respective planes through short vias (less than 5 mm length). Configuration mode pins (MSEL0, MSEL1) require external 1 kohm pull-up or pull-down resistors to select AS, PS, JTAG, or Fast Passive Parallel configuration. Differential clock inputs (CLK0-CLK3) must be length-matched within 25 mils and routed over a continuous ground reference to control impedance. Estimated: at 100 MHz toggle rates the device draws approximately 300-500 mA from VCCINT in typical designs.

Do not substitute the EP1C6T144C7 with Cyclone II, III, or IV parts in the same package footprint - pinout and configuration scheme differ. Quartus Prime (modern releases) does not include the Cyclone I device library; you must use Quartus II 13.0sp1 or earlier for compilation, which runs only on 32-bit Windows or Linux. The EP1C6 does not support live configuration updates the way Cyclone IV does; bit-stream updates require a full reconfiguration cycle. When designing for the industrial temp range, order the EP1C6T144I7N suffix rather than attempting to screen commercial parts. Estimated: a typical 60-70 percent logic-utilization design runs at 100-150 MHz internal frequency with proper timing closure.
