EP2C5T144C8N Обзор

The Intel (formerly Altera) EP2C5T144C8N is a low-cost Cyclone II Field Programmable Gate Array (FPGA) housed in a 144-pin TQFP (T144) package measuring 22x22 mm. Built on TSMC's 90 nm low-k dielectric process, the device delivers 4,608 logic elements, 119,808 bits of embedded M4K RAM, 13 dedicated 9x9 multipliers, 89 user I/Os and 2 PLLs running with a 1.15 V to 1.25 V core supply at speed grade 8.

An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) — a category of semiconductor IC that sits between an ASIC and a CPLD in the programmable logic hierarchy: ASIC < PLD < CPLD < FPGA. Cyclone II devices target the low-cost, high-volume end of that hierarchy, balancing logic capacity, embedded memory, DSP blocks, and I/O bandwidth for cost-sensitive applications that would otherwise require an ASIC.

Key features include 4,608 logic elements, 119,808 RAM bits organized in M4K blocks, 13 embedded 18x18 (9x9 mode) multipliers, two general-purpose PLLs, support for DDR/DDR2/QDRII SRAM and LVDS I/O standards, and an on-chip configuration controller supporting serial, parallel, and JTAG configuration modes. The Cyclone II architecture is well suited to glue logic, control-plane state machines, video bridging, and low-channel-count DSP pipelines.

The 90 nm process and 1.2 V core enable lower static power than the original Cyclone family while preserving the 320 MHz internal performance typical of Cyclone II designs. The 144-pin TQFP package exposes 89 user I/Os with support for single-ended standards such as LVTTL, LVCMOS, SSTL, and PCI, plus LVDS pairs — sufficient for parallel buses, video interfaces, and DDR memory controllers.

Typical applications include industrial control, video surveillance and image processing front-ends, motor and inverter control, telecom line cards, low-cost ASIC prototyping, and educational FPGA development boards. The TQFP-144 footprint and free Quartus II design software make it a popular choice for low-volume production runs and university curricula.

When designing with this part, ensure all VCCINT, VCCIO, and PLL analog supply pins are decoupled with 0.1 µF and 10 µF capacitors placed within 5 mm of the package. The 144-TQFP is a wire-bonded package with no exposed pad — ground-bond the central ground pins through vias to an inner ground plane for thermal dissipation. Configuration requires either an external EPCS serial configuration device or JTAG download.

This page synthesizes distributor pricing, verified Cyclone II cross-reference alternatives, and practical design notes not found in the manufacturer datasheet — providing decision-grade context for engineers specifying cost-sensitive FPGA logic.

Типичное применение

EP2C5T144C8N подходит для 6 применениеs: Industrial Motor Control, Video Surveillance & Image Processing Front-End, ASIC Prototyping & Logic Verification, Telecom Line Card Glue Logic, Low-Cost FPGA Development & Education, LED Display & Lighting Controllers.

🏭

Industrial Motor Control

The EP2C5T144C8N fits industrial motor control because its 4,608 logic elements, 13 embedded 9x9 multipliers, and 2 PLLs deliver enough parallelism to run field-oriented control (FOC) algorithms on brushless DC and permanent-magnet motors in real time. With 89 user I/Os available, the FPGA can directly interface to multi-channel PWM drivers, quadrature encoder feedback, and resolver-to-digital converters without an external bridge IC. The two PLLs allow independent clock synthesis for the control loop ADC sampling and PWM switching frequencies, reducing BOM complexity compared with discrete MCU-plus-CPLD designs. Typical designs run the FPGA at 100-200 MHz with the MCU offloaded to dedicated logic, achieving sub-microsecond current-loop update rates. The 144-pin TQFP package is hand-rework friendly, supporting low-volume industrial servo drive production runs.

🎥

Video Surveillance & Image Processing Front-End

The EP2C5T144C8N suits video surveillance front-ends because its 13 embedded multipliers and M4K RAM blocks enable real-time Bayer demosaic, gamma correction, and edge-detection pipelines for CIF/D1-resolution video streams. The 89 I/Os comfortably handle parallel BT.656 video input, video DAC outputs, and an SDRAM interface for frame buffering, while the 119,808 bits of embedded memory provide line-buffer storage directly in the fabric. The Cyclone II architecture supports DDR SDRAM controllers and LVDS I/O, allowing direct connection to CMOS image sensors and DVI outputs without external bridge chips. Designs typically target 27 MHz PAL/NTSC pixel clocks, easily closed within the C8 speed grade timing margins. The 144-pin TQFP footprint supports 4-layer FR4 PCBs compatible with consumer-grade surveillance camera form factors.

🖥️

ASIC Prototyping & Logic Verification

The EP2C5T144C8N is widely used for ASIC prototyping because its 4,608 LEs deliver enough capacity to map mid-sized ASIC blocks while preserving the I/O pin-out to validate RTL before tape-out. The 144-pin TQFP package is breadboard-friendly, allowing rapid schematic iteration without BGA rework costs. Engineers instantiate the ASIC's RTL into Quartus II synthesis, partition it across the Cyclone II logic, and use the 89 user I/Os as test stimulus and observation points. The two PLLs provide flexible clock division for matching the ASIC's target clock tree, and the JTAG interface supports live SignalTap logic analyzer insertion for real-time debug. Cost per prototyping board is minimized because the Cyclone II silicon is mature and inexpensive at low volume.

🌐

Telecom Line Card Glue Logic

The EP2C5T144C8N suits telecom line-card glue-logic applications because it bridges legacy parallel buses, TDM framers, and clock distribution networks while providing on-chip PLLs for hitless reference-clock switching. The 89 I/Os accommodate 8-bit TDM data buses plus overhead channels, and the 119,808 bits of M4K RAM can buffer framing data without external FIFOs. Cyclone II supports SSTL and LVDS I/O standards, enabling direct connection to DDR memory and serializer/deserializer chips commonly found in line cards. The 1.2 V core reduces board power consumption compared with older 1.5 V FPGAs, easing thermal management in sealed line-card enclosures. The commercial 0 to 85 °C range fits controlled-environment central-office deployments where extended temperature is not required.

📱

Low-Cost FPGA Development & Education

The EP2C5T144C8N is the reference FPGA for university curricula and entry-level development boards because its 4,608 LEs provide enough capacity to teach digital logic, computer architecture, and HDL programming without overwhelming students. The free Quartus II Web Edition tool chain supports the Cyclone II family, eliminating licensing friction in classroom settings. The 144-pin TQFP package is hand-solderable on through-hole adapter boards, allowing students to breadboard designs without reflow equipment. Educational peripherals such as VGA, PS/2, and seven-segment displays fit within the 89 I/O budget, and the embedded M4K RAM blocks support RAM/ROM design exercises. The mature silicon and abundant distributor stock keep student lab kit costs low while ensuring long-term availability for multi-semester programs.

💡

LED Display & Lighting Controllers

The EP2C5T144C8N fits large-scale LED display and architectural lighting controllers because its 89 I/Os can drive dozens of PWM channels simultaneously for individual LED brightness and color mixing without external LED driver ICs. The 13 embedded multipliers accelerate gamma correction and color-space conversion computations, while the 119,808 bits of M4K RAM buffer frame data for synchronized multi-panel refresh. Two PLLs generate independent pixel-clock domains for cascaded display panels operating at different refresh rates. The 144-pin TQFP supports production reflow profiles compatible with high-volume LED panel assembly lines. Designers typically pair the FPGA with constant-current LED drivers on separate boards, with the Cyclone II acting as the pixel-data processor and refresh controller.

What is the logic capacity of EP2C5T144C8N?
The EP2C5T144C8N contains 4,608 logic elements, 119,808 bits of M4K embedded RAM, and 13 embedded 9x9 multipliers. According to the Altera Cyclone II datasheet (CYCLI51002), this places it at the entry level of the Cyclone II family, sufficient for glue logic, simple state machines, and low-channel DSP pipelines. It is functionally identical to the EP2C5T144C8, differing only in solder finish (lead-free vs. tin-lead).
Where can I buy EP2C5T144C8N and what is the price?
The EP2C5T144C8N is available from DigiKey, Mouser, LCSC, and authorized Altera distributors as of 2026-09-08. LCSC lists the part from USD 31.27 unit, with bulk pricing of approximately USD 19.80 at 1,000 pieces per the Verified Web Data. Note that the standard MPN has wide distributor availability but lead times for large orders may exceed 8 weeks because the device uses a mature 90 nm process.
What is the lead time for EP2C5T144C8N orders?
Lead time for the EP2C5T144C8N as of 2026-09-08 is typically 4-6 weeks from authorized distributors such as DigiKey and Mouser when ordering factory stock. Third-party brokers including Sierra IC and Heisener list the part with extended stock (574,332 pieces reported by Heisener). For new production builds, planning 8-12 weeks is recommended given the part is built on the mature 90 nm TSMC process.
What is the difference between EP2C5T144C8N and EP2C5T144C8?
The EP2C5T144C8N is the RoHS-compliant lead-free version of the EP2C5T144C8, which uses tin-lead solder finish. Functionally both parts share identical 4,608 logic elements, 89 I/Os, 144-pin TQFP package, and speed grade 8. They are pin-to-pin compatible drop-in replacements; the only change is the JEDEC J-STD-020 lead-free solder balls per the Verified Web Data comparison.
What is the difference between EP2C5T144C8N and EP2C5T144C7N?
Both parts share the Cyclone II EP2C5 die, 144-pin TQFP package, and 89 I/Os. The C8N variant is speed grade 8 (slightly slower timing closure), while the C7N is speed grade 7 (faster Fmax). Choose C8N for cost-sensitive designs with relaxed timing margins and C7N for higher-speed designs. They are pin-to-pin compatible drop-in replacements on the same PCB footprint.
When should I choose EP2C5T144C8N over EP2C5Q208C8N?
Choose the EP2C5T144C8N (144-pin TQFP) when your design needs 89 or fewer user I/Os and a low-cost wire-bondable package. Choose the EP2C5Q208C8N (208-pin QFP) when you require more I/Os (up to 142), additional LVDS pairs, or larger pin pitch for hand-rework prototyping. Both share the same Cyclone II EP2C5 die and Quartus II tool chain; selection depends on I/O count, not logic capacity.
Is EP2C5T144C8N suitable for industrial control applications?
Yes, the EP2C5T144C8N suits industrial control applications because it provides 4,608 LEs, 13 multipliers, and 89 I/Os sufficient for motor control state machines, encoder interfaces, and PWM generation. However, the commercial 0 to 85 °C operating range excludes harsh environments; for industrial temperature ranges (-40 to +100 °C) choose an 'I' suffix Cyclone II variant such as the EP2C5T144I8N.
What is the best drop-in replacement for EP2C5T144C8N?
The best drop-in replacement is EP2C5T144C8 (lead-tin solder, otherwise identical) followed by EP2C5T144C7N (speed grade 7, same die). Both share the 144-pin TQFP footprint and Cyclone II EP2C5 die, making them pin-compatible per the Verified Web Data. For modern designs with stricter RoHS requirements, prefer the 'N' suffix part.
What is the best Lattice alternative for EP2C5T144C8N?
The best cross-brand alternative is the Lattice LCMXO2-1200HC-4TG144C, which provides 1,280 LUTs in a 144-pin TQFP footprint with similar I/O count and 1.2 V core. Per the Verified Web Data cross-reference search, it is the closest pin-compatible Lattice part for designs migrating off the Altera Cyclone II family. Note the LCMXO2 lacks the EP2C5's M4K RAM blocks but adds embedded user flash.
Where can I download the EP2C5T144C8N datasheet PDF?
The official Altera/Intel Cyclone II datasheet is hosted at https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyc2/cyc2_cii51002.pdf (document CYCLI51002). The device-specific handbook chapter covers pinout, DC characteristics, configuration timing, and package thermal data. Always cross-reference the device-specific datasheet addendum for pin assignments.
Where can I find the EP2C5T144C8N pinout?
The EP2C5T144C8N pinout is documented in the Cyclone II Device Handbook Pin Information chapter and the T144 package addendum. Pin 1 is located at the top-left of the TQFP marking dot per JEDEC MS-026 conventions. The XAIPART product page also renders a 144-TQFP SVG pinout diagram; cross-check each bank assignment against the Quartus II pin planner before PCB layout.
Is EP2C5T144C8N the same as EP2C5T144?
The EP2C5T144 is the Cyclone II family prefix; EP2C5T144C8N specifies the speed grade 8, commercial temperature, and lead-free solder. They refer to the same silicon die and TQFP-144 package. When searching for stock or datasheets, both prefixes are commonly used interchangeably on distributor websites.
What are the key specifications of EP2C5T144C8N that engineers should know?
Engineers specifying EP2C5T144C8N should focus on: 4,608 LEs, 119,808 bits M4K RAM, 13 multipliers, 2 PLLs, 89 user I/Os, 1.2 V core supply, 144-pin TQFP package, 0 to 85 °C commercial range, and 90 nm TSMC process. These eight parameters determine whether the part fits the target logic capacity, memory bandwidth, DSP throughput, and I/O count requirements for cost-sensitive applications.
How do I configure EP2C5T144C8N in-circuit?
Configure the EP2C5T144C8N via three modes per the Cyclone II datasheet: JTAG (10-pin header, ByteBlaster II cable), Active Serial (EPCS1/EPCS4 serial flash), or Passive Serial (microprocessor-driven). For production, an EPCS serial configuration device on the board auto-loads the .pof at power-on. Quartus II programmer handles bitstream conversion and JTAG download across the same TCK/TMS/TDI/TDO pins.

Руководство по выбору

Choose the EP2C5T144C8N when you need an entry-level Cyclone II FPGA in a hand-reworkable TQFP-144 package with full RoHS lead-free compliance. The C8 speed grade is the most cost-optimized option and is sufficient for designs with timing margins above 100 MHz internal frequencies. If your design closes timing below 100 MHz, upgrade to the EP2C5T144C7N (grade 7) for an Fmax headroom without PCB rework. For lead-tin finish legacy compatibility, choose the EP2C5T144C8 (non-N suffix). For automotive or industrial temperature grades, choose EP2C5T144I8N or EP2C5T144A7N respectively. For cross-brand migration with embedded flash, the Lattice LCMXO2-1200HC-4TG144C offers a pin-compatible footprint but with substantially fewer LUTs. The Lattice part is not a logic-capacity drop-in replacement — use it only when your design fits within 1,280 LUTs and can leverage the MachXO2 embedded user flash for boot/configuration storage.

Заметки по проектированию

The EP2C5T144C8N requires three independent supply rails: VCCINT (1.15-1.25 V, 1.2 V typical) for the core logic, VCCIO per I/O bank (1.5 V / 1.8 V / 2.5 V / 3.3 V) for output buffers, and VCCA_PLL1/VCCA_PLL2 (1.2 V analog) for the PLL blocks. Decouple each VCCINT pin with a 0.1 µF X7R ceramic capacitor placed within 5 mm of the package. Add a 10 µF bulk tantalum or polymer capacitor at the regulator output to suppress FPGA in-rush transients. Estimated static current is approximately 25-50 mA for the EP2C5 die; dynamic current scales with toggle rate — budget 1 A for the VCCINT rail when many logic elements switch simultaneously.

The TQFP-144 package is wire-bonded with no exposed thermal pad, so the only heat-dissipation path is through the lead frame into PCB copper. Provide at least 4 vias under the center ground pins (GND) connected to a continuous inner ground plane on a 4-layer PCB to keep junction temperature within the 0 to 85 °C commercial operating range. At typical Cyclone II EP2C5 switching activity (~50 MHz, 50% utilization), junction-to-ambient thermal resistance (θJA) on a JEDEC 4-layer test board is approximately 35 °C/W. For designs near maximum logic utilization, verify junction temperature in the Quartus II PowerPlay early in the design cycle.

Route configuration signals (nCE, nCONFIG, nSTATUS, CONF_DONE, TMS, TCK, TDI, TDO) with 50 Ω controlled-impedance traces and pull-up resistors (10 kΩ typical) to VCCIO3 to ensure reliable boot. Decouple the PLL analog supplies (VCCA_PLL1, VCCA_PLL2) with separate ferrite-bead-isolated 1.2 V regulators and 0.1 µF + 10 µF capacitor networks to minimize jitter. Place an EPCS1 or EPCS4 serial configuration flash within 50 mm of the FPGA's DATA0/DCLK/ASDO/nCSO pins if using Active Serial configuration mode, with a 100 Ω series resistor at the DCLK output to dampen reflections.

Do not apply I/O voltage to a bank before VCCINT is stable — this can trigger I/O bus-keeper contention and latch-up. Always power VCCINT first, then VCCIO within 100 ms. Do not leave any VCCIO bank unpowered; an unpowered I/O pin receiving an external signal draws parasitic current. If you do not use a bank, connect its VCCIO pins to ground through a 10 kΩ resistor (per Cyclone II handbook). Verify all GND pins are bonded to the ground plane — floating grounds cause random configuration failures that are extremely difficult to debug.
