EP2C8T144I8N Visão geral

The Intel (formerly Altera) EP2C8T144I8N is a low-cost Cyclone II Field-Programmable Gate Array (FPGA) built on a 90 nm low-k dielectric process and offered in a 144-pin Thin Quad Flat Pack (TQFP) package. The device integrates 8,256 logic elements (LEs), 165,888 bits of embedded RAM organized as 36 M4K memory blocks, and 85 user I/O pins with support for multiple I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and PCI.

An FPGA (Field-Programmable Gate Array) is a reconfigurable digital integrated circuit whose logic fabric, interconnect, and I/O can be customized by the end user after manufacture using a hardware description language such as Verilog or VHDL. Within the broader semiconductor taxonomy, FPGAs sit at the top of the programmable-logic hierarchy above CPLDs (Complex Programmable Logic Devices) and below fixed-function ASICs (Application-Specific Integrated Circuits). The Cyclone II family specifically targets low-density, cost-sensitive applications where ASIC non-recurring engineering cost is not justified.

Key specifications include 36 embedded 18x18 multipliers supporting up to ~250 MHz DSP performance, two PLLs for clock management, configuration via active serial (AS), passive serial (PS), or JTAG, and an industrial temperature range of -40C to +100C. The 144-TQFP package exposes 85 user I/O pins and supports 1.2 V core operation with multi-voltage I/O banks at 1.5 V, 1.8 V, 2.5 V, or 3.3 V.

The Cyclone II architecture pairs 4-input look-up tables (LUTs) with embedded memory blocks to implement logic, DSP, and simple microcontroller functions on a single chip. The part is supported by the Quartus II design toolchain, which provides synthesis, place-and-route, timing analysis, and bitstream generation for configuration via a JTAG header or EPCS configuration flash.

Typical applications include industrial motor and motion control, video processing bridges, low-density communications glue logic, education and FPGA training platforms, and prototype ASIC replacement. Cyclone II devices were widely adopted in mid-2000s designs and remain useful for long-lifecycle industrial systems where re-qualification costs discourage migration to newer families.

When designing with this part, ensure the core decoupling network follows the Cyclone II handbook guidelines - typically 0.1 uF and 10 uF capacitors near every VCCINT/VCCIO pin pair. Configuration mode selection via MSEL pins must match the configuration device in use, and unused I/O pins should be set to tri-state with weak pull-up via Quartus device options to minimize in-rush current during configuration.

Aplicações típicas

EP2C8T144I8N é adequado para 6 aplicaçãos: Industrial Motor Control, Video Processing Bridges, Communications Glue Logic, FPGA Education and Training Platforms, Prototype ASIC Replacement, Legacy Industrial System Maintenance.

🏭

Industrial Motor Control

The EP2C8T144I8N is well suited to industrial motor control inverter logic where its 8,256 logic elements can implement field-oriented control (FOC) state machines, PWM generators, and encoder interfaces simultaneously on a single die. Its 36 embedded 18x18 multipliers execute the Clarke and Park transforms plus the inverse Park transform needed for stator current control, while the 85 user I/O pins accommodate three-phase PWM outputs, incremental encoder inputs, and parallel current-sense ADC interfaces. The industrial -40C to +100C temperature grade tolerates cabinet-mounted factory environments without derating. Designers should pair the FPGA with external gate drivers such as the IR2110 or UCC27211 because the FPGA outputs cannot directly switch the IGBT or SiC module gates.

📺

Video Processing Bridges

The EP2C8T144I8N serves as a video format bridge converting between DVI, HDMI, VGA, and LVDS display interfaces in mid-complexity digital signage and industrial display products. The 165,888 bits of embedded RAM organize as 36 M4K blocks to implement line buffers for resolution scaling and frame-rate conversion, while the 36 18x18 multipliers accelerate color-space conversion from YCbCr to RGB. The 144-TQFP package exposes 85 user I/O pins, enough for 24-bit parallel RGB plus control signals and the LVDS link. Cyclone II has no hard HDMI transceiver, so external TFP410 / TFP401A serializer chips or ADV7513 HDMI transmitters handle the physical layer while the FPGA manages pixel clock generation and timing.

🌐

Communications Glue Logic

In telecom and networking hardware the EP2C8T144I8N provides protocol conversion and front-panel glue logic between ASICs, network processors, and SERDES devices. Its two PLLs generate the multiple clock domains typical in communications backplanes, while the 8K logic elements implement stateful protocol handlers for SPI, I2C, UART, MDIO, and PCIe-style sideband signals. The 85 user I/O pins easily accommodate 16-bit parallel buses plus differential LVDS pairs for inter-board links. Cyclone II lacks multi-gigabit transceivers, so the part is appropriate for control-plane glue rather than data-path packet processing, where it can replace a stack of discrete 74-series logic.

🧩

FPGA Education and Training Platforms

The EP2C8T144I8N appears in university FPGA teaching labs and on open-spec development boards where students learn Verilog and VHDL digital design. The 8K-LE density is large enough to host an entire 32-bit RISC-V soft core, a VGA framebuffer, and a UART bootloader simultaneously, yet small enough to fit comfortably in the Quartus II toolchain's free Web Edition license. The 144-TQFP package is hand-solderable with care on breakout boards, and the industrial temperature grade lets the same board survive laboratory and maker-fair environments. The mature Cyclone II device support in older Quartus versions means legacy lab tutorials and reference designs remain directly compilable for the part.

🔧

Prototype ASIC Replacement

Designers use the EP2C8T144I8N as a prototype vehicle for ASIC designs that have not yet taped out, allowing pre-silicon firmware development and system integration testing on real hardware. The Cyclone II silicon integrates 165 Kbits of RAM and 36 multipliers sufficient to model many common ASIC IP blocks, and the Quartus II toolchain provides full timing closure visibility so that ASIC sign-off scripts can be back-annotated. The 144-TQFP package exposes 85 user I/O pins that map comfortably onto typical ASIC ball-outs after a small interposer board, and the industrial temperature grade lets the prototype go into environmental chambers that mimic final product conditions.

🏭

Legacy Industrial System Maintenance

Long-lifecycle industrial systems installed in the late 2000s and early 2010s often contain Cyclone II FPGAs whose original bill of materials has since been discontinued, and the EP2C8T144I8N supports the field-replacement market for these products. The part's identical pin-out and Quartus II compatibility mean that a field engineer can swap a failed FPGA with a fresh unit loaded from the original programming file without board rework. The 144-TQFP footprint is well-documented in legacy design files, and remaining last-time-buy inventory on the open market supports repair depots through approximately the end of the decade.

What is the logic element count of the EP2C8T144I8N?

The EP2C8T144I8N integrates 8,256 logic elements (LEs) on a Cyclone II fabric manufactured on TSMC's 90 nm low-k process. According to the Cyclone II Device Handbook, each LE contains a 4-input LUT, a programmable register, and dedicated carry and cascade chains that combine to implement combinational and sequential logic for glue logic, control, and DSP pipelines in cost-sensitive designs.

How many user I/O pins does the EP2C8T144I8N expose in the TQFP-144 package?

The EP2C8T144I8N exposes 85 user I/O pins in its 144-pin TQFP package, with the remaining package pins allocated to power, ground, JTAG, configuration, and dedicated clock inputs. According to the device pin-out table in the Cyclone II handbook, the eight I/O banks each support independent VCCIO rails of 1.5 V, 1.8 V, 2.5 V, or 3.3 V, enabling mixed-voltage interfacing on the same die.

What configuration modes does the EP2C8T144I8N support?

The EP2C8T144I8N supports active serial (AS), passive serial (PS), and JTAG configuration, selected via the MSEL[2:0] pins at power-up. According to the Cyclone II Device Handbook, AS mode loads the bitstream from an EPCS serial configuration flash, PS mode accepts bitstream from an external host or microcontroller, and JTAG mode provides in-system programming through a standard 4-wire IEEE 1149.1 test access port.

Where can I buy the EP2C8T144I8N online and what is the current price?

The EP2C8T144I8N is available from distributors including DigiKey, Mouser, LCSC, and Octopart-listed suppliers, with single-piece pricing around $27.86 USD as of 2026-09-09. Note that Cyclone II devices are in their last-time-buy window, so distributors may show limited stock and longer lead times; ordering in production volumes requires confirmation of remaining factory inventory or third-party broker stock.

What is the lead time for the EP2C8T144I8N given its last-time-buy status?

The EP2C8T144I8N is flagged last-time-buy, meaning Intel has issued a final buy notice and remaining stock is finite. Lead times as of 2026-09-09 vary by distributor: in-stock reels at DigiKey and Mouser ship immediately, while larger production orders may require allocation or sourcing from independent distributors like LCSC at higher unit prices. Plan a last-time-buy now if a long-lifecycle program depends on this part.

Is the EP2C8T144I8N currently in stock at major distributors?

Stock levels for the EP2C8T144I8N fluctuate as remaining last-time-buy inventory is consumed. As of 2026-09-09, LCSC reports active inventory starting at approximately $27.86 USD per unit, while DigiKey and Mouser listings show intermittent stock. Always check real-time inventory on distributor websites or via Octopart aggregator before committing to a production schedule, since Cyclone II inventory is being depleted globally.

What is the best drop-in replacement for the EP2C8T144I8N?

The best drop-in replacement for the EP2C8T144I8N in the same 144-pin TQFP package is the EP2C8T144C8N, which shares identical pinout, package, and silicon but operates in the commercial 0C to +85C temperature range. According to the Cyclone II ordering information table, the only differences are temperature grade (C8 vs I8) and speed grade equivalence; designers needing industrial temperature must use the -I8N variant, which cannot be replaced by the -C8N version in harsh environments.

EP2C8T144I8N vs EP2C8T144C8N - which should I choose?

Choose EP2C8T144I8N when your design must operate across the industrial -40C to +100C range, including factory automation, outdoor equipment, and automotive under-hood applications. Choose EP2C8T144C8N for benign commercial environments (0C to +85C) such as indoor consumer electronics, lab equipment, or FPGA development boards. Both parts share the identical 144-TQFP pinout and Cyclone II 8K-LE silicon, so the selection is purely a temperature-grade decision.

When should I choose the EP2C8T144I8N over a Cyclone IV or Cyclone V equivalent?

Choose the EP2C8T144I8N only when re-spinning an existing Cyclone II design, maintaining long-lifecycle industrial equipment, or working with a legacy Quartus II toolchain where a board-level re-spin would be prohibitively expensive. For new designs, select Cyclone IV E (EP4CE6E144) or Cyclone V (5CEBA4F23) instead, since these newer families offer higher logic density, lower static power, modern transceivers, and active long-term support - none of which the discontinued Cyclone II line provides.

Is the EP2C8T144I8N suitable for new industrial control designs in 2026?

The EP2C8T144I8N is not recommended for new designs in 2026 because Intel has issued a last-time-buy notice, meaning long-term supply is no longer guaranteed. The part remains acceptable only for legacy product maintenance, low-volume replacement orders, and existing PCB re-spins where component compatibility is mandatory. New industrial control designs should target Cyclone IV E, Cyclone 10 LP, or Lattice ECP5 / MachXO3 families with active production commitments.

Where can I download the EP2C8T144I8N datasheet PDF?

The EP2C8T144I8N datasheet can be downloaded from the Alldatasheet archive at the link provided on this page, or from the Intel FPGA legacy documentation portal which hosts the Cyclone II Device Handbook covering electrical characteristics, pin-out tables, timing specifications, and configuration schematics. The Device Handbook is approximately 470 pages and is the authoritative reference; many third-party distributors host PDF mirrors but always cross-check pin-out tables against the official source before committing a layout.

Where can I find the EP2C8T144I8N pinout diagram for PCB layout?

The EP2C8T144I8N pinout for the 144-pin TQFP package is documented in Chapter 6 of the Cyclone II Device Handbook, which assigns each package pin to a bank, an I/O number, and dedicated functions such as clock inputs, JTAG signals, and configuration pins. Quartus II Pin Planner also imports the package and produces a graphical pad-by-pad view; engineers should consult both sources when designing the PCB footprint and routing the JTAG chain.

What are the key specifications of the EP2C8T144I8N that engineers should know?

The EP2C8T144I8N provides 8,256 logic elements, 165,888 bits of embedded RAM in 36 M4K blocks, 36 18x18 multipliers, two PLLs, 85 user I/O pins, configuration via AS / PS / JTAG, a 1.2 V core supply, multi-voltage I/O banks, and an industrial -40C to +100C temperature range in a 144-pin TQFP package. The headline density figure of 8K LEs places this part at the lower end of the Cyclone II family, suitable for glue logic, motor control, and small DSP pipelines.

What is the difference between EP2C8T144I8N and EP2C5T144I8N?

The EP2C8T144I8N provides 8,256 logic elements while the EP2C5T144I8N provides only 4,608 logic elements, both in the same 144-pin TQFP package and industrial temperature grade. According to the Cyclone II family ordering information, both parts share the same pin-out, so the EP2C5 is a lower-density drop-in for cost-sensitive applications. Choosing between them is a function of design resource utilization - if Quartus reports above ~70 percent LE usage on the EP2C5, step up to the EP2C8.

Guia de seleção

Choose the EP2C8T144I8N when you need an industrial-temperature 8K-LE Cyclone II FPGA in the 144-TQFP package for legacy product maintenance, industrial motor control, or communication glue logic. Select the EP2C8T144C8N for benign commercial environments (0C to +85C) to access slightly larger remaining stock at lower unit cost. Choose the EP2C5T144I8N when Quartus II reports below 70 percent LE utilization and you want to optimize the BOM cost on the same footprint. Select the EP2C8AT144I8N for AEC-Q100 automotive programs that must survive +125C under-hood environments. For all new designs starting in 2026, migrate to Cyclone IV E, Cyclone 10 LP, or Lattice ECP5 / MachXO3 because Cyclone II is on last-time-buy and Intel has stopped accepting new long-term orders. All six alternatives listed in this page share the identical 144-TQFP pinout, so PCB layout reuse is preserved across the entire family.

Notas de projeto

The EP2C8T144I8N requires a low-noise 1.2 V core supply on every VCCINT pin plus per-bank VCCIO supplies of 1.5 V, 1.8 V, 2.5 V, or 3.3 V depending on the I/O standard in use. Per the Cyclone II Device Handbook, place one 0.1 uF X7R ceramic bypass capacitor directly adjacent to every VCCINT and VCCIO pin pair, supplemented by a single 100 uF bulk tantalum or aluminum-polymer capacitor at the regulator output. Estimated: the 8K-LE Cyclone II typically draws 200 mA to 400 mA on VCCINT at 100 percent toggle activity, so the 1.2 V regulator must deliver at least 500 mA with 50 mV peak-to-peak ripple.

Route the JTAG chain (TCK, TMS, TDI, TDO) on the top layer with a continuous ground return path immediately below, and keep trace lengths matched to within 50 mil to avoid timing skew during boundary-scan testing. The MSEL[2:0] pins must be tied to VCCIO8 or GND through 4.7 K resistors and not left floating, since a floating MSEL can cause the device to enter an undefined configuration mode and appear as a configuration failure. Place the EPCS configuration flash within 4 inches of the FPGA DATA0 / DCLK pins to avoid signal-integrity issues during AS-mode boot.

The 144-pin TQFP package has no exposed thermal pad, so heat removal relies entirely on copper pours connected to the GND pins and forced airflow. Estimated: at 100 percent LE utilization and 100 MHz toggle rate, the part dissipates approximately 0.5 W to 1.0 W; this is manageable in a properly ventilated industrial enclosure but should be verified with a thermal probe at maximum ambient. Designers should fill unused package area with a continuous GND copper pour stitched with vias to the inner ground plane.

Do not leave unused I/O pins floating in the Quartus II pin planner - set them to 'As input tri-stated with weak pull-up' via Device Options, otherwise the inputs can float into the linear region and draw extra supply current during configuration. Cyclone II does not support hot-socketing on JTAG pins, so add 4.7 K series resistors on TCK, TMS, TDI, and TDO if the board will be mated while powered. Configuration failures from corrupted bitstreams are almost always traced to insufficient VCCINT decoupling or to a CONFIG_DONE pin pulled low by leakage; verify both before assuming a silicon failure.

LVDS outputs on the EP2C8T144I8N require a 100 ohm differential termination resistor placed within 250 mil of the receiver input, and the differential pair must be routed with a 100 ohm controlled-impedance trace on a stripline or microstrip layer stack. Single-ended I/O signals exceeding 50 MHz should be series-terminated at the source with a 33 ohm resistor to dampen reflections on long traces. Use the Quartus II TimeQuest timing analyzer with a properly constrained SDC file to verify all paths meet setup and hold requirements before generating the final bitstream.
