EP1C6T144I-7 개요

The Altera (now Intel) EP1C6T144I-7 is a member of the Cyclone family of low-cost Field Programmable Gate Arrays (FPGAs) fabricated on a 130 nm process. It integrates 5,980 logic elements, 92,160 bits of embedded RAM organized in M4K blocks, and two PLLs into a 144-pin LQFP package (TQFP, 0.5 mm pitch). The device is rated for an industrial operating temperature range of -40 °C to +100 °C and supports a core supply voltage of 1.5 V with I/O banks tolerant of common logic standards.

A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs) connected via programmable interconnect, allowing designers to implement arbitrary digital logic, glue logic, DSP pipelines, and parallel processing engines after PCB assembly. Within the power-management and embedded-system hierarchy, the Cyclone family belongs to the low-cost SRAM-based FPGA category, positioned below high-performance Stratix devices and above CPLDs in terms of density and DSP capability. The 130 nm CMOS process and 1.5 V core make EP1C6T144I-7 a mature, low-power entry point.

Key features of the EP1C6T144I-7 include 5,980 logic elements, 92,160 embedded RAM bits (twenty M4K blocks of 4,608 bits each), a maximum internal clock frequency up to 320 MHz (speed grade -7), two general-purpose PLLs with four output taps each, and 98 maximum user I/O pins. The device also integrates a JTAG boundary-scan interface, supports configuration via passive serial, active serial, or JTAG modes, and is supported by the Quartus II / Quartus Prime design toolchain. The '-7' speed grade denotes one of the faster Cyclone tiers.

Architecturally, the Cyclone device pairs four-input look-up tables (LUTs) with small embedded memory blocks, enabling efficient shift-register, FIFO, and DSP-style FIR filtering implementations without external memory. The two PLLs provide on-chip clock multiplication and phase shifting, eliminating many external clock-generator ICs. Combined with the LVDS, LVTTL, SSTL, and PCI I/O standards supported, EP1C6T144I-7 is engineered for high-volume cost-sensitive applications that require integration density beyond discrete CPLDs.

Typical applications include industrial control and instrumentation, motor-control front-ends, consumer-electronics glue logic, embedded video processing for legacy CCTV and digital signage, telecommunications line-card glue logic, and educational / FPGA-training platforms. The 144-pin LQFP package allows hand-soldering and rework on 2-layer prototype boards, which is a key reason this part persists in low-volume production despite newer Cyclone generations.

When designing with EP1C6T144I-7, note that the part contains lead (Pb) and is not RoHS compliant - for RoHS designs, use EP1C6T144I7N or newer Cyclone devices. The 1.5 V core requires a dedicated LDO regulator, and all four PLL analog supply pins (VCCA_PLL) must be decoupled with 0.1 µF and 10 µF capacitors per the datasheet typical application circuit.

This page synthesizes distributor pricing, drop-in same-brand alternatives from the Cyclone family, and practical design notes not found in the bare manufacturer datasheet.

일반적인 애플리케이션

EP1C6T144I-7 적합 용도: 6 애플리케이션s: Industrial Control & Automation, Motor Control Front-End, Consumer Electronics Glue Logic, Embedded Video Processing, Telecom Line-Card Glue Logic, FPGA Education & Training Platforms.

🏭

Industrial Control & Automation

The EP1C6T144I-7 fits industrial control applications because its 5,980 logic elements and 92,160 bits of embedded RAM can implement multiple protocol bridges (Modbus, RS-485, CAN glue logic) plus a soft CPU core such as Nios II on a single device. The industrial -40 °C to +100 °C temperature range covers factory-floor ambient conditions, and the 144-LQFP package is hand-solderable for prototyping. Two integrated PLLs provide deterministic clock generation for deterministic motor-control loops.

🏭

Motor Control Front-End

For motor-control front-ends the EP1C6T144I-7 generates PWM signals with sub-microsecond resolution using its 320 MHz internal clock divided through the on-chip PLLs. The 92 Kbits of M4K RAM allow implementation of sine-lookup tables and field-weakening curves without external memory. With 98 user I/O pins the device can simultaneously drive three-phase PWM, capture encoder feedback, and interface an HMI display - all on the same 1.5 V core with the 144-LQFP package enabling 2-layer prototype PCBs.

📱

Consumer Electronics Glue Logic

The EP1C6T144I-7 is well-suited to consumer glue logic because its 5,980 LEs can replace dozens of discrete 74-series logic ICs, shrinking BOMs and reducing PCB area. Typical designs integrate I2C/SPI bridges, LCD controllers, key-scan matrices, and audio sample-rate converters on one chip. The 144-LQFP hand-solderable package supports small production runs, and the 1.5 V core keeps power dissipation low. Lead-free N-suffix variants (EP1C6T144I7N) are mandatory for consumer products sold in RoHS jurisdictions.

📺

Embedded Video Processing

For embedded video applications the EP1C6T144I-7 implements ITU-R BT.656 capture pipelines, color-space converters (YCrCb to RGB), and on-screen-display overlays in a single FPGA. The 92 Kbits of M4K RAM serve as line buffers for de-interlacing and scaling, while the 320 MHz clock supports real-time processing of SD video (27 MHz pixel clock). With 98 user I/O the device can also drive an LCD panel directly, eliminating an external graphics controller IC for legacy CCTV and digital signage designs.

🌐

Telecom Line-Card Glue Logic

Telecom line cards use the EP1C6T144I-7 for HDLC framing, E1/T1 transceiver interfaces, and time-slot switching across TDM buses. The two PLLs synthesize the 2.048 MHz E1 and 1.544 MHz T1 clocks from a single 8 kHz backplane reference, eliminating dedicated clock-generator ICs. The 92 Kbits of embedded RAM provide elastic stores for clock-rate adaptation, and the industrial temperature grade covers central-office and outside-plant enclosures. LVTTL/LVCMOS I/O standards interface directly to legacy framer ASICs.

🧩

FPGA Education & Training Platforms

Educational labs and FPGA training kits use the EP1C6T144I-7 because the 144-LQFP package is hand-solderable, allowing students to assemble and rework development boards. 5,980 LEs is enough to teach combinational logic, sequential logic, finite state machines, soft CPU cores, and basic DSP all on one chip. The Cyclone family is supported by Quartus II Web Edition (free) which provides simulator, synthesizer, and programmer. Tutorials written for the Cyclone EP1C6 are still in circulation at most universities.

What is the maximum operating frequency of EP1C6T144I-7?
The Altera EP1C6T144I-7 supports a maximum internal operating frequency of 320.1 MHz at speed grade -7. According to the Cyclone family datasheet, this figure represents the maximum toggle rate of internal logic; achievable Fmax for any specific user design depends on routing, logic depth, and I/O standard. Designers should run Quartus II fitter reports to confirm system-level performance.
How many logic elements and RAM bits does EP1C6T144I-7 contain?
The EP1C6T144I-7 integrates 5,980 logic elements (4-input LUTs plus associated registers) and 92,160 bits of embedded RAM arranged as 20 M4K blocks of 4,608 bits each. The M4K blocks can be configured as single- or dual-port RAM, ROM, or shift registers, supporting FIFO, lookup-table, and small DSP buffer applications without external memory.
What package and pin count does EP1C6T144I-7 use?
The EP1C6T144I-7 ships in a 144-pin LQFP package (also referred to as TQFP) with a 0.5 mm lead pitch and 22 mm × 22 mm body size. The 144-LQFP package provides 98 maximum user I/O pins after subtracting power, ground, JTAG, and configuration pins. The exposed lead-frame enables hand-soldering and rework, which is ideal for prototype builds.
Is EP1C6T144I-7 RoHS compliant?
No. The EP1C6T144I-7 contains lead (Pb) in its lead finish and is not RoHS compliant. According to the Cyclone family datasheet, for RoHS-compliant designs the recommended drop-in alternative is EP1C6T144I7N (lead-free) or migrating to a newer Cyclone generation. The lead-bearing variant persists for legacy industrial and military programs where lead-based solder is mandatory.
Where can I buy EP1C6T144I-7 and what is the current price?
As of 2026-09-06, the EP1C6T144I-7 is listed at DigiKey, Arrow, and Octopart-indexed distributors, primarily as obsolete / last-time-buy stock. Qty-1 unit pricing is approximately $38.50; qty-100 drops to roughly $27.95; qty-1000 is around $18.75 per unit. Stock is limited because the part is end-of-life - check each distributor for current inventory before placing orders.
What is the lead time for EP1C6T144I-7 orders?
Lead time for EP1C6T144I-7 varies by distributor because the part is obsolete and only inventory remains. As of 2026-09-06, DigiKey lists the part with same-day shipping where stock exists; Arrow and authorized resellers typically ship within 1-3 business days. For large orders, expect lead times of 2-6 weeks if sourcing from secondary-market inventory.
What is the best drop-in replacement for EP1C6T144I-7?
The best drop-in replacement for EP1C6T144I-7 in the same 144-LQFP package is EP1C6T144I7N, which is the lead-free RoHS-compliant version of the same die. Functionally, EP1C6T144I8N (speed grade -8, slightly slower) is also a drop-in option. For new designs consider migrating to Cyclone II EP2C5T144 or Cyclone III EP3C5E144, though those are not pin-compatible.
EP1C6T144I-7 vs EP1C6T144I7N - what is the difference?
The EP1C6T144I-7 and EP1C6T144I7N are functionally identical die in the same 144-LQFP package. The only meaningful difference is lead finish: EP1C6T144I-7 contains lead (Pb) and is not RoHS compliant; EP1C6T144I7N is lead-free and RoHS compliant. All electrical and timing specifications are identical, making EP1C6T144I7N a true drop-in replacement for new designs.
What software is needed to program EP1C6T144I-7?
The Altera Quartus II design software (versions 4.x through 13.0) supports EP1C6T144I-7 bitstream generation. Newer Quartus Prime releases no longer include the Cyclone (original) device family, so designers must retain Quartus II 13.0 or earlier. Programming is performed via JTAG using a USB-Blaster, ByteBlaster, or compatible download cable with .pof or .sof files.
Where can I download the EP1C6T144I-7 datasheet PDF?
The EP1C6T144I-7 datasheet is hosted as part of the Altera Cyclone Family datasheet on Alldatasheet.com and Intel's legacy Altera support page. A 94-page PDF covering all Cyclone family devices is available at the Alldatasheet URL listed in the data sources of this page. For configuration, pinout, and timing specifications refer to the Cyclone Device Handbook.
What is the core voltage and how should EP1C6T144I-7 be powered?
EP1C6T144I-7 requires a 1.5 V core supply (VCCINT) with typical tolerance of ±5%, plus a separate 3.3 V supply for the I/O banks (VCCIO) which can be set per bank. The two PLL analog supplies (VCCA_PLL1, VCCA_PLL2) require a clean 1.5 V derived through an LC or ferrite-bead filter from VCCINT. Designers should use a dedicated LDO such as an LT1761 or TPS7A45 to generate VCCINT from a 3.3 V or 5 V rail.
What is the difference between Cyclone and Cyclone II FPGAs?
Cyclone (original, EP1C) is the 130 nm first-generation family with up to 20,060 LEs and 288 Kbits of RAM. Cyclone II (EP2C) is the 90 nm successor with up to 68,416 LEs, 1.1 Mbits of RAM, and embedded 18×18 multipliers for DSP. Cyclone II parts are not pin-compatible with original Cyclone - any migration requires PCB redesign. For new designs with EP1C6-class density needs, Cyclone III or later is recommended.
How many PLLs does EP1C6T144I-7 have and what are they used for?
EP1C6T144I-7 contains 2 general-purpose PLLs, each with 4 clock output taps. PLLs are used for clock multiplication, division, phase shifting, and duty-cycle adjustment, allowing designers to derive multiple frequencies from a single low-frequency crystal or oscillator. The PLL outputs can drive global clock networks or be routed to general-purpose interconnects. VCCA_PLL pins must be filtered per the datasheet typical application circuit.
Is EP1C6T144I-7 suitable for new product designs in 2026?
EP1C6T144I-7 is not recommended for new product designs in 2026 because the part is obsolete, not RoHS compliant, and supported only by legacy Quartus II 13.0 toolchains. Engineers building new products should migrate to Cyclone IV E (EP4CE6E144) or Cyclone 10 LP (10CL006E144) in compatible footprints. EP1C6T144I-7 remains relevant only for maintaining legacy equipment, replacement spares, and educational training on classic FPGA architectures.

선택 가이드

Choose EP1C6T144I-7 only when you are maintaining or replicating a legacy industrial design that was qualified with the lead-bearing variant, or for educational platforms where legacy non-RoHS components are acceptable. For new industrial designs select EP1C6T144I7N - identical die, same 144-LQFP package, but lead-free and RoHS compliant. For cost-sensitive commercial products choose EP1C6T144C7N (commercial temp grade, lower cost). For designs requiring more I/O than 98 pins, migrate to EP1C6Q240I7N (240-PQFP, 185 I/O) - but note this is a footprint change. For all new products in 2026, recommend migrating to a current-generation FPGA such as Cyclone IV E EP4CE6E144 or MAX 10 10M02SCE144, which are pin-compatible successors with active lifecycle status.

설계 노트

EP1C6T144I-7 requires a clean 1.5 V core (VCCINT) with a tolerance of ±5% (1.425 V - 1.575 V). Use a dedicated LDO regulator such as a TPS7A4533 or LT1761-1.5 to generate VCCINT from a 3.3 V or 5 V rail. The two PLL analog supply pins (VCCA_PLL1, VCCA_PLL2) must each be filtered with a ferrite bead and decoupled with 0.1 µF + 10 µF capacitors per the Cyclone datasheet typical application circuit. VCCIO for each I/O bank can be set independently to 1.5 V, 1.8 V, 2.5 V, or 3.3 V for mixed-voltage interfacing.

Decoupling capacitor placement is critical for Cyclone FPGAs. Place one 0.1 µF ceramic capacitor per VCCINT pin within 100 mil (2.5 mm) of the pin, plus bulk 33 µF tantalum or 100 µF aluminum-polymer capacitors on the board for transient load handling. GND should use a continuous low-impedance plane; avoid split ground planes under the FPGA. JTAG signals (TCK, TMS, TDI, TDO) should be routed with 4-mil traces and a ground reference on the adjacent layer.

Although the 144-LQFP package has a relatively high thermal resistance (θJA ≈ 35 C/W), Cyclone EP1C6 typical quiescent current is only 250 mA at 1.5 V (≈ 0.4 W), so additional heatsinking is rarely required. Under full logic utilization at 320 MHz the device can draw up to 1 A (≈ 1.5 W). Estimated: at 1.5 W dissipation in still air the junction temperature rises about 52 C above ambient - within industrial 100 C limit. Forced-air cooling is recommended only in sealed enclosures.

Three common pitfalls: (1) EP1C6T144I-7 is lead-bearing - do not use it in RoHS-compliant products; choose EP1C6T144I7N instead. (2) Configuration Flash (EPCS1/EPCS4) must be programmed with .pof file generated by Quartus II - .sof files are RAM-only and lost on power cycle. (3) Original Cyclone is supported only by Quartus II versions up to 13.0; Quartus Prime 14.0+ removed device support. Retain the legacy toolchain or migrate to Cyclone IV E.
