EP2C5T144I8N Présentation

The Intel (formerly Altera) EP2C5T144I8N is a low-cost Cyclone II Field-Programmable Gate Array (FPGA) housed in a 144-pin TQFP package, offering 4,608 logic elements (LEs) and 119,808 bits (approximately 117 Kbits) of embedded memory. Built on a 1.2 V, low-power SRAM process, it operates over the industrial temperature range (-40C to +85C) and features 89 user I/O pins with LVDS support in select banks, delivering a balance of density, performance, and cost for high-volume applications.

What is an FPGA? A Field-Programmable Gate Array is a reconfigurable semiconductor device containing an array of logic blocks (lookup tables, flip-flops, and routing) that can be programmed after manufacture to implement arbitrary digital logic. Within the broader taxonomy, an FPGA belongs to programmable logic devices (PLD) -> logic ICs -> integrated circuits. The Cyclone II family positioned FPGAs as affordable alternatives to ASICs in cost-sensitive designs, making programmable logic accessible to consumer, industrial, and communications markets where earlier FPGAs had been economically impractical.

Key features include 4,608 LEs, 119,808 RAM bits distributed across M4K memory blocks, 13 embedded 18x18 multipliers for DSP-style workloads, and support for multiple I/O standards including LVTTL, LVCMOS, PCI, and LVDS. The device supports configuration via serial (AS) or parallel (PS) modes and contains built-in JTAG boundary-scan for in-system programming. Eight global clock networks plus two PLLs per quadrant (when present) simplify timing closure for synchronous designs across the 144-pin footprint.

Architecturally, Cyclone II uses a 90 nm process with a Stratix-derived routing fabric adapted for low-cost positioning. Multipliers are wired to 9-Kbit memory blocks, enabling efficient DSP and FIFO implementations without consuming logic fabric. Internal configuration bits are stored in SRAM, requiring an external configuration flash or download cable on every power-up.

Typical applications include industrial motor control, low-cost video processing, protocol bridging, USB and Ethernet interface logic, educational FPGA development boards, and consumer electronics glue logic. The wide operating temperature range also supports outdoor industrial deployments.

When designing with this device, verify that the I/O bank voltage references match the chosen signaling standard; mis-referenced VCCIO rails are a common board-bring-up failure. Also confirm the configuration scheme (AS vs PS) supports your boot-time budget.

Applications typiques

EP2C5T144I8N convient pour 6 applications: Industrial Motor Control, Low-Cost Video Processing Bridge, Protocol Bridging (USB / Ethernet / UART), Educational FPGA Development Boards, Consumer Electronics Glue Logic, Test & Measurement Front-End Logic.

🏭

Industrial Motor Control

The EP2C5T144I8N fits industrial motor-control designs because its 4,608 LEs and 13 embedded 18x18 multipliers are sufficient for field-oriented control (FOC) algorithms, encoder decoding, and PWM generation on a single chip. The industrial -40C to +85C temperature range covers cabinet-mounted drives, and the 89 user I/O pins handle quadrature encoder inputs, Hall sensors, and gate-driver enable signals. Compared with a microcontroller, this FPGA can execute the control loop at much higher PWM frequencies (above 100 kHz), reducing audible switching noise and improving torque ripple. Power estimation per Cyclone II datasheet: 1.2 V core at typical 250 mA plus I/O bank current. Place bypass capacitors as close to each VCCIO and VCCINT pin pair as the 144-TQFP land pattern allows.

📺

Low-Cost Video Processing Bridge

The EP2C5T144I8N is widely used as a video-format bridge (BT.656 to parallel RGB, or HDMI input to LVDS output) in cost-sensitive consumer and prosumer products. The 4,608 LEs hold a line buffer plus color-space conversion, and the M4K memory blocks provide FIFO buffering of video lines. LVDS support in selected I/O banks permits direct connection to LVDS panels without external buffers. Engineers should budget 25-30% LE utilization for typical color-space conversion plus timing controller logic, leaving headroom for additional overlay or graphics processing. The 144-TQFP package is hand-solderable for prototype builds, which is unusual for an FPGA of this density.

🌐

Protocol Bridging (USB / Ethernet / UART)

When a host processor lacks a particular peripheral, the EP2C5T144I8N can implement glue logic that bridges between standards - for example, USB 2.0 high-speed to parallel FIFO, or 100 Mbit Ethernet MAC plus UDP offload. The device's JTAG interface enables in-field firmware updates, and 119,808 bits of embedded RAM comfortably hold packet buffers for typical industrial protocols. Designers should use Altera's soft IP cores (Nios II, Triple-Speed Ethernet, USB) with Quartus II 13.0sp1, the last version with full Cyclone II support. Power sequencing: bring up VCCINT (1.2 V) before VCCIO and CONF_DONE pin within 100 ms of configuration start.

🎓

Educational FPGA Development Boards

Universities and hobbyists favor the EP2C5T144I8N because it balances density, hand-solderability, and price. The 144-TQFP is the largest pitch that is still practical to hand-solder with a fine-tip iron, and 4,608 LEs is enough to teach a full RISC-V soft core, VGA controller, and audio pipeline simultaneously. Reference designs ship with EPCS4 configuration flash, 50 MHz clock, SRAM, LEDs, and pushbuttons, allowing students to focus on HDL rather than board bring-up. Quartus II Web Edition remains free and supports this device without a license, which keeps the total learning cost minimal.

📱

Consumer Electronics Glue Logic

In consumer products such as set-top boxes, printers, and home appliances, the EP2C5T144I8N replaces multiple discrete logic ICs by integrating level shifting, display timing, button debouncing, and LED control. Consolidation from 4-6 standard-logic chips to one FPGA reduces PCB area, BOM count, and assembly cost. The industrial temperature variant (this part) is preferred for products sold into global markets where warehouse and shipping conditions may briefly exceed commercial-grade limits. Estimated static power: ~50 mW at typical use; dynamic power depends on toggle rate and should be simulated with the Quartus PowerPlay tool.

🔧

Test & Measurement Front-End Logic

Test instruments and ATE fixtures use the EP2C5T144I8N to implement custom stimulus generation, response capture, and protocol-aware handshake logic between the device under test (DUT) and the host. The 13 embedded multipliers can compute CRC, checksum, or simple FFT pre-processing in-line with sample acquisition, while M4K blocks provide double buffering. With 89 user I/O pins the FPGA can directly drive up to 11 LVDS pairs (using LVDS in supported banks) or 89 single-ended signals, often sufficient to replace a mid-range ASIC in low-volume test gear.

What is the logic element count of EP2C5T144I8N?

The EP2C5T144I8N contains 4,608 logic elements (LEs) according to the Cyclone II Device Handbook. This entry-level density in the Cyclone II family makes it suitable for glue-logic, control, and low-throughput DSP tasks where higher-density FPGAs would be overkill.

How much embedded memory does EP2C5T144I8N have?

The EP2C5T144I8N provides 119,808 bits of embedded RAM organized into M4K memory blocks, equivalent to approximately 117 Kbits. Each M4K block can be configured as RAM, ROM, or FIFO and supports true dual-port operation for parallel data paths.

How many user I/O pins does EP2C5T144I8N provide?

The EP2C5T144I8N exposes 89 user I/O pins across 4 I/O banks in the 144-TQFP package, leaving 55 pins reserved for supply, ground, JTAG, and configuration. Bank-based VCCIO references allow mixing of I/O standards such as LVTTL, LVCMOS, PCI, and LVDS on the same device.

What is the operating temperature of EP2C5T144I8N?

The 'I' suffix in EP2C5T144I8N designates the industrial temperature range of -40C to +85C, making the device suitable for outdoor enclosures, factory automation, and automotive-cabin (non-powertrain) applications where commercial-grade parts would fail.

Is EP2C5T144I8N RoHS compliant?

Yes. The EP2C5T144I8N is RoHS compliant per Altera/Intel product declarations and uses lead-free finish suitable for reflow profiles up to 260C peak. The 144-TQFP package is MSL-3 rated, so dry-pack handling and floor-life tracking are required.

Where can I download the EP2C5T144I8N datasheet PDF?

The official Cyclone II Device Handbook (Volume 1, approximately 470 pages) covering the EP2C5T144I8N is available from the Altera/Intel literature archive. The most reliable mirror is the legacy Altera site at https://www.altera.com/literature/hb/cyc2/cyc2_handbook.pdf, which is the canonical datasheet referenced in this product page.

Although the Cyclone II family has been superseded by Cyclone IV and Cyclone 10, Intel continues to support existing customers and authorized distributors still hold meaningful inventory, including 18,528 pieces listed at Heisener.

What is the difference between EP2C5T144I8N and EP2C5T144C8N?

The EP2C5T144I8N (industrial, -40C to +85C) and EP2C5T144C8N (commercial, 0C to +85C) share identical logic resources, package, and pinout. The only difference is the operating temperature grade. Choose the I-grade variant for outdoor or industrial deployments; the C-grade is sufficient for benign indoor consumer and laboratory environments.

EP2C5T144I8N vs EP2C8T144C8N - which should I choose?

The EP2C5T144I8N offers 4,608 LEs and the EP2C8T144C8N offers 8,256 LEs in the same 144-TQFP package, so they are footprint-compatible. Choose EP2C5T144I8N when 4,608 LEs are sufficient for the design; choose EP2C8T144C8N when extra logic, more multipliers (18 vs 13), or additional I/O headroom are needed at a modest cost premium.

Can EP2C8T144I8N replace EP2C5T144I8N as a drop-in?

Yes, the EP2C8T144I8N in the same 144-TQFP package is a drop-in upgrade. The pinout is identical, core voltage is the same at 1.2 V, and the larger device offers 8,256 LEs versus 4,608 with 18 embedded multipliers versus 13. Existing bitstreams designed for EP2C5 must be recompiled because of resource-density differences, but no PCB rework is needed.

When should I choose EP2C5T144I8N over a newer Cyclone 10 LP?

Choose EP2C5T144I8N when cost is the dominant constraint and the design fits within 4,608 LEs, especially when an existing Cyclone II toolchain and IP are already in place. Choose a Cyclone 10 LP device for new designs needing lower static power, modern transceivers, updated IDE support, and a longer active lifecycle guarantee.

What is the best cross-brand replacement for EP2C5T144I8N?

There is no true cross-brand drop-in replacement for the EP2C5T144I8N because the pinout, configuration interface, and JTAG ID are Intel/Altera-specific. Cross-brand functional equivalents exist (e.g., Lattice iCE40 or Xilinx Spartan-6 in similar density), but they require PCB rework, tool-chain migration, and full re-verification of the bitstream.

Guide de sélection

Choose EP2C5T144I8N when you need an FPGA in the 4,608-LE density range with industrial -40C to +85C temperature support in a hand-solderable 144-TQFP package. It is the right pick for motor control, industrial glue logic, and educational boards that may be deployed in non-climate-controlled environments. If your design fits in 4,608 LEs and will only see indoor commercial temperatures, choose EP2C5T144C8N to save cost. If you anticipate resource growth, design the PCB for EP2C5T144I8N today and migrate to EP2C8T144I8N later - the footprint is identical. For new designs requiring long lifecycle guarantees and modern transceivers, evaluate Cyclone 10 LP instead.

Notes de conception

Estimated: Cyclone II core current at typical 4,608-LE utilization is roughly 200-300 mA from a 1.2 V VCCINT rail; each VCCIO bank adds up to 100 mA depending on toggle rate. Provide a 1.2 V LDO or switching regulator rated for at least 500 mA, and add 0.1 uF ceramic bypass capacitors within 5 mm of every VCCINT and VCCIO pin. Decoupling values: one 10 uF bulk + one 0.1 uF per pin pair is the conservative Cyclone II recommendation.

The 144-TQFP 22x22 mm package uses 0.5 mm pitch leads; route with 0.15 mm/6 mil traces and use a 4-layer PCB with continuous ground plane beneath the device for return-current control. All eight GND pins must be soldered to the ground plane with multiple vias to reduce inductance. Place the EPCS configuration flash within 25 mm of the FPGA, keep DCLK short, and add a 25-50 ohm series termination on DCLK if the trace exceeds 50 mm.

Configuration fails on first power-up if VCCINT and VCCIO rise-time relationships are violated: VCCINT must reach 1.0 V within 100 ms and VCCIO must follow within 100 ms afterward. Stratix II and Cyclone II use different MSEL pull-up/pull-down schemes; verify MSEL[2:0] against the Cyclone II handbook (not Cyclone III/IV) before board fab. Avoid leaving unused I/O pins floating - configure them as outputs driving low or as inputs with internal weak pull-up to prevent shoot-through during configuration.

Estimated: at maximum junction temperature +85C industrial limit, the 144-TQFP requires approximately 26 C/W theta_JA still-air thermal resistance to keep die temperature below 85C when dissipating 1 W. Cyclone II typically dissipates 0.5-1.5 W at moderate utilization, so no heatsink is needed but PCB copper area (at least 4 sq cm on top layer) is recommended for margin. Forced airflow is rarely required unless utilization exceeds 80%.
