EP2C5T144C8N - Cyclone II FPGA 4,608 LEs 89 I/O 144-TQFP | Intel
MPN: EP2C5T144C8N ✓ Hoạt độngEP2C5T144C8N Tóm tắt
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.

Ứng dụng tiêu biểu
EP2C5T144C8N phù hợp cho 6 Áp dụngs: 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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.
Được đề xuất
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.

Ghi chú thiết kế
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.
