EP2C5T144C6N Présentation
A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose digital logic functionality is defined after manufacturing by the customer, via a configuration bitstream. FPGAs sit in the broader taxonomy: programmable logic device (PLD) -> FPGA -> SRAM-based FPGA -> Cyclone II family. They differ from ASICs by offering rapid prototyping, field re-programmability, and lower NRE cost, while trading off per-unit cost and absolute performance against fixed-function ASICs. Cyclone II is positioned in the low-density, low-power tier below the Cyclone III/IV/V families.
Key features include up to 89 user I/O pins across 4 I/O banks, embedded 18x18 multipliers (13 total) for DSP-style arithmetic, dual-purpose configuration pins, and JTAG boundary-scan (IEEE 1149.1) for in-system programming and boundary test. The device supports multiple configuration modes including AS, PS, JTAG, and FPP, enabling flexible boot from EPCS serial flash or microprocessor hosts. The 144-pin LQFP package is plastic and surface-mount with 0.5mm pitch, suited to standard SMT assembly lines without requiring BGA-grade inspection.
Cyclone II FPGAs use a logic element (LE) granularity built around 4-input look-up tables (LUT4), each with an associated carry chain and register. The M4K embedded RAM blocks (13 blocks of 4,608 bits each) deliver true dual-port operation up to 250 MHz and can be configured as RAM, ROM, or FIFO buffers. Phase-locked loops (PLLs) provide clock multiplication, division, and phase shifting across the 2-4 PLLs available per device.
Typical applications include industrial motor control front-ends, low-density protocol bridges (UART/SPI/I2C to Ethernet), LED display controllers, video processing front-ends, educational development boards, and low-cost DSP pipelines. The Cyclone II is well-suited to designs where pin count and logic density demand exceed microcontrollers but ASIC NRE cannot be amortized.
When designing, plan for JTAG access (TCK/TMS/TDO/TDI pulled appropriately), 2.5V/3.3V bank voltage compatibility, decoupling per power pin, and configuration storage via EPCS1/EPCS4 serial flash. The LQFP-144 package benefits from generous copper pours and routed differential pairs for LVDS signals where jitter budget matters.

Applications typiques
EP2C5T144C6N convient pour 7 applications: Industrial Motor Control FPGA, Legacy Protocol Bridge (UART/SPI to Ethernet), LED Video Wall Controller, Educational FPGA Development Platform, Video Processing Front-End (CVBS / HDMI Capture), Low-Cost DSP Pipeline (FIR / FFT), Automotive Infotainment Auxiliary Logic.
Industrial Motor Control FPGA
The EP2C5T144C6N fits industrial motor control front-ends because its 89 user I/O across 4 banks support direct interfacing to multi-axis encoder inputs (QEP, Hall sensors), PWM outputs, and isolation-barrier GPIO. The 13 embedded 18x18 multipliers and 4,608 logic elements handle real-time field-oriented control (FOC) loops with adequate headroom for sinusoidal commutation and current-loop PI controllers. With 2 PLLs available, multiple PWM carrier frequencies can be synthesized cleanly from a single crystal reference.
Recommandé
Legacy Protocol Bridge (UART/SPI to Ethernet)
In low-volume industrial gateways, the EP2C5T144C6N bridges UART/SPI/I2C peripherals to Ethernet MAC interfaces (MII/RMII) using soft IP cores. Its 119,808 bits of embedded RAM provide FIFO buffering for packet reassembly, while 89 I/O pins accommodate multiple serial ports plus an external PHY connection. The Cyclone II architecture supports soft-core processors (NIOS II) at clock rates sufficient for Modbus, Profibus, or MQTT translation.
Recommandé
LED Video Wall Controller
The EP2C5T144C6N drives entry-level LED video walls by combining HUB75-style parallel LED outputs with simple refresh-rate timing logic. Its 4 I/O banks can supply independent 3.3V and 2.5V signaling for mixed logic levels between LED driver ICs and host controllers. Embedded M4K RAM blocks serve as scan-line buffers, and the 89 I/O count maps to moderate-resolution panels (typically up to 256x64 pixels) at 60Hz refresh.
Recommandé
Educational FPGA Development Platform
Cyclone II EP2C5T144C6N has long been a teaching workhorse in university digital logic labs because of its 144-pin LQFP hand-solderable footprint, balanced logic density (4,608 LEs), and free Quartus II Web Edition support. Students learn HDL synthesis, timing analysis, and peripheral interfacing on a chip that is forgiving but representative of real FPGA design flow. The T144 package is breadboard-adapter friendly with break-out PCBs.
Recommandé
Video Processing Front-End (CVBS / HDMI Capture)
The EP2C5T144C6N handles composite video (CVBS) decoding, color-space conversion, and scaling for low-cost video recorders. Its 4,608 LEs can host ITU-R BT.601 processing pipelines, and LVDS pairs in the LQFP-144 package support HDMI/DVI receiver interface ICs (e.g., TFP401). M4K RAM blocks implement line buffers for deinterlacing and frame-rate conversion at standard-definition resolutions.
Recommandé
Low-Cost DSP Pipeline (FIR / FFT)
Cyclone II FPGAs implement moderate-density DSP functions via their 13 embedded 18x18 multipliers and 4-input LUTs. The EP2C5T144C6N can host FIR filters (up to 13 taps parallel at full speed), FFT butterflies, or audio-bandwidth DDC chains for software-defined radio front-ends. Its 2 PLLs support sample-rate clock synthesis alongside logic-clock domains.
Recommandé
Automotive Infotainment Auxiliary Logic
The AEC-Q100 qualified EP2C5AT144A7N variant in the same T144 footprint supports automotive infotainment subsystems where it manages CAN/LIN routing, button-debouncing logic, and LCD segment timing. Automotive-grade qualification is the key parameter here, justifying use of the EP2C5AT144A7N over the commercial EP2C5T144C6N despite both sharing the same LQFP-144 pinout.

Principaux différenciateurs
- Standard timing class in the Cyclone II family (vs EP2C5T144C8N)
- Commercial temperature range (vs EP2C5T144I7N)
- 144-pin LQFP hand-solderable footprint (vs XC3S50A-4TQG144I)
Notes de conception
The EP2C5T144C6N requires a 1.15V to 1.25V VCCINT core supply and per-bank VCCIO supplies at 1.5V, 1.8V, 2.5V, or 3.3V. Estimated: at typical 25C ambient and 50% toggle rate, the EP2C5 core draws approximately 70-150 mA from VCCINT depending on utilization; place 0.1uF ceramic decoupling caps adjacent to every VCCINT pin and bulk 100uF tantalum on the supply plane. Power-on sequencing requires VCCINT to ramp before or simultaneously with VCCIO; failure to do so can cause I/O latch-up per the Cyclone II Device Handbook.
The LQFP-144 package has a 0.5mm pitch; per Altera layout guidelines, route all signals on inner layers and place via-in-pad for ground stitching beneath the package. For LVDS pairs used in clock or video I/O, maintain 100 ohm differential impedance with length matching of +/- 10 mils. Estimated: copper pour area of at least 1 square inch on the top layer is recommended to dissipate the 0.5-2W typical dissipation of an EP2C5 design without dedicated thermal relief.
Do not leave MSEL pins floating - they configure the boot mode (AS, PS, JTAG) and incorrect setting prevents bitstream loading. Pull-ups on nCONFIG and pull-downs on nSTATUS as documented in the Cyclone II handbook are mandatory. Configuration bitstream storage should use EPCS1 or EPCS4 serial flash; legacy EPC2 parallel flash is no longer recommended. The T144 package does not include an exposed thermal pad - thermal management relies on copper pour area and ambient airflow.
Decouple each VCCIO bank with at least one 0.1uF ceramic capacitor per pin pair and one bulk 10uF tantalum per bank. JTAG signals (TCK, TMS, TDI, TDO) must be routed with 50 ohm controlled impedance if traces exceed 25 mm; route TMS and TDI with pull-ups to VCCIO of the bank they belong to. Configuration clock DCLK must be clean - any glitches on DCLK during AS mode will cause configuration failure and require power cycling.
Informations de conformité
