EP2C8T144C7 Ringkasan

The Intel EP2C8T144C7 is a member of the Cyclone II family of low-cost FPGAs, offering 8,256 logic elements, 165,888 bits of embedded memory, and 18 embedded 18x18 multipliers in a 144-pin TQFP package. Operating with a core voltage of 1.15V to 1.25V (commercial grade) and I/O voltages compatible with 1.5V, 1.8V, 2.5V, 3.0V, and 3.3V standards, the device is fabricated on a 90 nm low-k CMOS process with a 1.2V core supply, providing a favorable balance of logic density, DSP performance, and unit cost.

A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable routing, and dedicated hard IP such as memory blocks and multipliers. Within the broader taxonomy, an FPGA belongs to programmable logic devices -> logic ICs -> integrated circuits -> semiconductors. The Cyclone II family specifically targets cost-sensitive, high-volume applications where ASICs are uneconomical but microcontrollers lack the parallelism or I/O bandwidth required.

The EP2C8T144C7 supports up to 85 user I/O pins through the 144-pin TQFP, includes four phase-locked loops (PLLs) for clock management, and supports configuration via active serial (AS), passive serial (PS), and JTAG modes. The 165,888 embedded RAM bits are organized in M4K blocks of 4,608 bits each, allowing efficient buffering for video, communications, and DSP pipelines.

Architecturally, the 8,256 logic elements are arranged in 516 logic array blocks (LABs), each containing 16 LEs. The 18 embedded 18x18 multipliers support DSP workloads such as FIR filters, FFTs, and motor control loops at throughputs not achievable with soft multipliers in earlier FPGA families.

Typical applications include digital signal processing front-ends, video processing and display controllers, industrial control and motor drive, low-cost software-defined radio (SDR) prototyping, and glue logic replacement on legacy boards. The TQFP-144 footprint supports conventional SMT assembly without BGA-style via-in-pad complications, simplifying prototyping and low-volume production.

Designers should note that Cyclone II is a mature legacy family: design entry is via the Quartus II (legacy) toolchain. When migrating, target Cyclone IV E or Cyclone V for newer designs requiring lower power, more logic, or transceivers. For LQFP-144 designs requiring more logic, EP2C20F484 or EP2C35F484 in larger packages are common upgrades.

🔧

Digital Signal Processing Front-End

The EP2C8T144C7's 18 embedded 18x18 multipliers and 165,888 RAM bits make it well suited to DSP front-ends for industrial instrumentation, audio processing, and sensor conditioning. Each multiplier operates up to approximately 250 MHz in Cyclone II, enabling real-time FIR filters, Goertzel detectors, and FFT pipelines at sample rates suitable for vibration, acoustic, and biomedical front-ends. The 36 M4K RAM blocks provide dual-port buffering for sample streams, while the 8,256 logic elements handle state machines, address generators, and glue logic around the DSP datapath. Design tip: pipeline multiplier chains at the DSP block boundary to meet timing closure at speed grade 7; use the four PLLs to derive multiple synchronized DSP clocks from a single reference.

Video Processing and Display Controller

The EP2C8T144C7 in TQFP-144 supports 85 user I/O pins, enough to drive 24-bit RGB video at common resolutions while leaving headroom for side-band control signalling. Cyclone II devices were widely adopted in industrial flat-panel controllers, surveillance DVRs, and entry-level video scalers. The four PLLs synthesize pixel clocks from common reference frequencies (27 MHz for video, 74.25 MHz for HD), while M4K blocks implement line buffers and frame buffers without external SRAM. Performance consideration: at speed grade 7 the design comfortably drives VGA at 60 Hz and XGA at lower rates; for higher resolutions consider an EP2C20F484 or EP2C35F484 in a larger package with more multipliers and memory.

Industrial Motor Control and Drive

The EP2C8T144C7 is a strong fit for digital motor control loops including field-oriented control (FOC), trapezoidal BLDC commutation, and stepper sequencing. The 18 18x18 multipliers handle Clarke/Park transforms and PID computation in real time, while the M4K RAM blocks capture encoder feedback and provide lookup tables for sine/cosine acceleration profiles. The TQFP-144 package supports conventional SMT assembly and is well suited to factory-floor PCBs exposed to vibration and thermal cycling. Design tip: use one PLL to derive the PWM carrier and a second PLL to sample the encoder; the four PLLs decouple these clocks and minimize jitter on the PWM edges.

Low-Cost Software-Defined Radio Prototyping

The EP2C8T144C7 has been a popular entry point for SDR prototyping on ham-radio transceivers, narrowband IQ demodulators, and educational SDR kits. Its 18 DSP multipliers support polyphase FIR decimation and channelization filters at audio-bandwidth sample rates; the M4K memory implements delay lines and FFT working buffers. The 85 user I/O pins can directly interface dual-channel ADCs and DACs without external glue logic. While not a replacement for dedicated SDR silicon (e.g., AD9361), the EP2C8 lets students and hobbyists implement real-time DSP algorithms with full visibility into the HDL. Note: Cyclone II is fixed-point only; floating-point routines must be hand-coded.

Legacy Glueless Logic Replacement

The EP2C8T144C7 in TQFP-144 is commonly used to replace aging PLDs, GALs, and discrete 74-series logic on legacy industrial PCBs. With 8,256 logic elements, the device can absorb dozens of legacy 74-series packages into a single FPGA, reducing board area and improving reliability. The TQFP-144 footprint supports conventional rework tooling used in industrial maintenance. Engineers often start by capturing the legacy schematic as HDL, then iterating against the existing test vectors. Performance consideration: a typical glue-logic replacement converts 5-10 legacy ICs into a single EP2C8, freeing the rest of the device for incremental feature upgrades.

Educational FPGA Development Board

The EP2C8T144C7 has powered countless university and hobbyist FPGA development boards because the TQFP-144 package is hand-solderable and the Cyclone II toolchain (legacy Quartus II) is freely available. Students learn HDL synthesis, place-and-route, timing closure, and configuration on a device with enough logic and DSP for substantial projects (RISC-V cores, VGA controllers, signal-processing exercises). The 85 user I/O pins expose ample GPIO, while the 4 PLLs teach clock-tree concepts. Note: new university curricula typically migrate to Cyclone IV E (EP4CE6E22) or Cyclone V boards because of active lifecycle support and the current Quartus Prime toolchain.

What is the EP2C8T144C7 and what family does it belong to?
The EP2C8T144C7 is a Cyclone II FPGA from Intel (formerly Altera) in the 144-pin TQFP package. It contains 8,256 logic elements, 36 M4K memory blocks totaling 165,888 RAM bits, 18 embedded 18x18 multipliers, 4 PLLs, and up to 85 user I/O pins. The 'C7' suffix denotes the commercial temperature grade (0C to +85C) with speed grade 7.
What is the difference between EP2C8T144C7 and EP2C8T144C8?
The EP2C8T144C8 is the faster speed grade 8 variant of the same Cyclone II EP2C8 die in the 144-pin TQFP package. Speed grade 8 meets tighter timing closure than speed grade 7 and is preferred when the design approaches the Fmax limit of the device. Both share identical logic, memory, multiplier, and I/O resources; pinout is identical, so they are drop-in interchangeable on the same PCB.
What is the difference between EP2C8T144C7 and EP2C8T144C6?
The EP2C8T144C6 is the slower speed grade 6 variant of the same EP2C8 die in the 144-pin TQFP package. Speed grade 6 is the slowest Cyclone II speed bin and is typically selected when timing margin is comfortable and lower-cost units are preferred. All three speed grades (6, 7, 8) share an identical pinout and are pin-for-pin drop-in compatible in TQFP-144.
Where can I download the EP2C8T144C7 datasheet PDF?
The official Cyclone II device datasheet is published on the Intel FPGA product page (formerly Altera). Search 'Cyclone II Device Handbook' on intel.com or reference the legacy Altera Cyclone II literature (document CII51002). Distributor listings on DigiKey and Mouser also link directly to the manufacturer datasheet PDF. The datasheet contains electrical characteristics, pinout, timing, and configuration specifications for the entire EP2C family.
Where to buy EP2C8T144C7 and what is the current price?
As of 2026-09-09, EP2C8T144C7 is available from authorized distributors including DigiKey, Mouser, and several specialist FPGA inventory brokers (ic2ic, Nantian, ampheo). Reference pricing for qty 1 is approximately 48.41 USD; volume pricing drops to roughly 28.75 USD at qty 1000. Note that the device is approaching end-of-life, so stock should be verified before placing volume orders; long lead times of 12-26 weeks have been reported.
Is EP2C8T144C7 in stock or do I need to plan for a long lead time?
Per 2026-09-09 distributor data, EP2C8T144C7 is in limited stock. Authorized distributors occasionally carry small quantities; many brokers list the part with lead times of 12-26 weeks. Because Cyclone II is a mature family nearing end-of-life, designers should confirm inventory before committing to new production. For long-term availability, plan a redesign to Cyclone IV E or Cyclone V.
What is the lead time for EP2C8T144C7?
Lead time for EP2C8T144C7 is typically 12-26 weeks as of 2026-09-09, depending on the distributor. Authorized channels like DigiKey and Mouser list it with stock-dependent ship dates; brokers and open-market suppliers such as Nantian and ampheo list 12-16 week delivery windows. Customers needing production volumes should secure allocation now or migrate to a newer family such as Cyclone IV E.
What is a drop-in replacement for EP2C8T144C7?
The best drop-in replacements for EP2C8T144C7 in the same 144-pin TQFP footprint are the other speed-grade variants EP2C8T144C6, EP2C8T144C6N, EP2C8T144C7N, and EP2C8T144C8N. The 'N' suffix indicates lead-free / RoHS-compliant reflow. If a logic-density upgrade is acceptable, the EP2C8T144 family also overlaps in pinout with larger EP2C devices in TQFP-144. For modern drop-in designs, consider Cyclone IV E EP4CE6E22 in a different package.
EP2C8T144C7 vs EP2C8T144C7N - which should I choose?
The EP2C8T144C7 is the standard lead-containing package; the EP2C8T144C7N is the lead-free / RoHS-compliant variant of the same die. The 'N' suffix indicates lead-free matte-tin plating and RoHS compliance. Both share the identical TQFP-144 pinout and are drop-in compatible on the same PCB; choose the C7N variant when RoHS compliance is required (e.g., EU shipments), otherwise the C7 variant may offer slightly better pricing.
What is the maximum operating frequency of EP2C8T144C7?
The maximum internal operating frequency of the EP2C8T144C7 is application-dependent and varies with logic depth, temperature, and voltage. According to the Cyclone II Device Handbook, the C7 speed grade targets approximately 450 MHz internal performance for simple paths. DSP blocks and memory interfaces support lower but still high-throughput rates; refer to the Quartus II timing analyzer for design-specific Fmax closure.
How many user I/O pins does EP2C8T144C7 provide?
The EP2C8T144C7 provides up to 85 user I/O pins in the 144-pin TQFP package. This is the maximum for the EP2C8 family in this package; I/O banks support 1.5V, 1.8V, 2.5V, 3.0V, and 3.3V signalling standards. Eight I/O banks allow mixed-voltage interfacing with multiple system components on a single board.
What is the difference between Cyclone II and Cyclone III FPGA families?
Cyclone II (the EP2C8 family) is built on a 90 nm process and targets cost-sensitive applications; Cyclone III uses a more efficient 65 nm process delivering up to 50 percent lower power and greater logic density. Cyclone III also offers more memory and multipliers per LE. For new designs requiring Cyclone III or later, ensure the Quartus toolchain is at least version 13.1 or newer; Cyclone II designs use the legacy Quartus II toolchain.
What design software is required to program EP2C8T144C7?
The EP2C8T144C7 is programmed using the legacy Altera Quartus II design toolchain (versions 9.0 through 13.1). Quartus II Web Edition is a free download with full Cyclone II support. The design flow covers HDL entry (VHDL/Verilog), synthesis, place-and-route, timing analysis, and bitstream generation. Configuration to the device is via JTAG (USB-Blaster) or an Altera EPCS serial configuration device.
What is the best cross-brand alternative to the EP2C8T144C7?
The best cross-brand alternative to the EP2C8T144C7 in a similar low-cost FPGA category is the Xilinx Spartan-3E XC3S100E in TQFP-144, which targets comparable logic density and I/O count. Note, however, that Spartan-3E is not pin-for-pin compatible - it uses the Xilinx toolchain (ISE/Vivado) and a different package layout. For modern drop-in replacements in the same footprint, the same-brand EP2C8 speed-grade variants are preferred.

Panduan Pemilihan

Choose the EP2C8T144C7 when you need a low-cost, hand-solderable TQFP-144 FPGA with 8,256 logic elements, 4 PLLs, and a mature toolchain for an industrial, motor-control, or SDR prototyping design. The lead-bearing C7 variant is acceptable for non-RoHS markets where component cost or long-term availability favors legacy supply chains. For RoHS-required shipments, switch to EP2C8T144C7N (lead-free, same die, same pinout). For timing-critical designs, choose EP2C8T144C8 or EP2C8T144C8N (speed grade 8, tighter Fmax). For cost-sensitive timing-relaxed designs, EP2C8T144C6 or EP2C8T144C6N (speed grade 6). For industrial temperature operation (-40C to +100C), select EP2C8T144I8N. For new designs with longer lifecycle requirements, migrate to Cyclone IV E EP4CE6E22 (different package, different toolchain support).

Diferensiator Kunci

  • TQFP-144 hand-solderable footprint (vsEP2C8F256 (BGA package))
  • Cyclone II maturity with ample toolchain documentation (vsNewer Cyclone IV E / EP4CE6E22)
  • Pin-for-pin speed-grade flexibility (vsEP2C8T144C7N (lead-free only))

Catatan Desain

The EP2C8T144C7 requires two supply rails: VCCINT (1.15-1.25 V core) and VCCIO (per-bank I/O voltage, 1.5/1.8/2.5/3.0/3.3 V). Decouple each VCCINT pin with a 0.1 uF X7R ceramic capacitor placed within 5 mm of the pin; each VCCIO bank requires a 0.1 uF + 10 uF bulk capacitor pair. Estimated: at typical utilization (50% LE, 50% RAM, 50% DSP) and 100 MHz, VCCINT current is roughly 200-300 mA; a 1.5 A LDO or switching regulator headroom is recommended. Add a power-good reset supervisor tied to nCONFIG for clean configuration startup.

Route configuration signals (nSTATUS, nCONFIG, DCLK, DATA0, MSEL[3:0]) with 50 ohm controlled impedance and keep them short (< 50 mm) to avoid reflections during configuration. Place the EPCS serial configuration flash within 25 mm of DCLK/DATA0 with a ground guard trace between signals. The TQFP-144 package has standard 0.5 mm pitch and supports conventional SMT assembly on 4-layer FR-4 with no via-in-pad - a significant reliability advantage over BGA FPGA packages for hand-prototyping and rework.

Dedicated clock input pins (CLK[0..3]) feed the global clock network and should be driven by low-jitter (< 50 ps RMS) sources; route clock traces as 50 ohm microstrip with length matching within 5 mm across differential pairs. For DDR-style interfaces, use the Cyclone II DDR registers in the IOE and place DQ/DQS traces with matched length within +/-25 ps (approx 5 mm on FR-4). When interfacing with 3.3 V peripherals, configure the I/O bank VCCIO to 3.3 V; mixing 3.3 V and 1.8 V signalling requires separate banks.

Do not confuse the Cyclone II EP2C8 (90 nm, 1.2 V core, 8,256 LE) with the Cyclone III EP3C8 (65 nm, lower power) or Cyclone IV E EP4CE8 - they are different families with different bitstreams and JTAG IDs. Confirm the Quartus II toolchain version supports Cyclone II (9.0-13.1). Avoid using Cyclone III/Cyclone V/MAX device libraries against a Cyclone II target; bitstreams are NOT compatible across families. Also, when migrating from EP2C8T144C7 to a lead-free equivalent, ensure the assembly profile supports the higher reflow temperatures required for matte-tin (N-suffix) packages.
