EP1C3T144C7N - 2,910 LEs Cyclone FPGA 144-LQFP | Intel
MPN: EP1C3T144C7N ✗ پایان تولیدEP1C3T144C7N نمای کلی
A Field Programmable Gate Array (FPGA) is a reconfigurable integrated circuit built from a matrix of programmable logic blocks (LEs), interconnect, and embedded memory that engineers can configure after manufacture to implement any digital logic function. In the power-management hierarchy, FPGAs sit alongside processors, ASICs, and ASSPs as the highest-flexibility programmable logic option, typically after the voltage regulator and clock tree in a system block diagram. The Cyclone series targets cost-sensitive, high-volume designs where ASIC NRE is not amortisable.
Key features include 2,910 logic elements, 59,904 embedded RAM bits, one PLL per device, 104 user I/Os (LVTTL/LVCMOS, SSTL, LVDS capable), and support for external memory interfaces such as DDR SDRAM and QDR SRAM. The 144-LQFP package offers a 1.0 mm lead pitch and an exposed thermal pad for improved heat dissipation in surface-mount reflow profiles, enabling hand-reworkable prototypes and production volumes alike.
Architecturally, the Cyclone LE combines a 4-input look-up table (LUT) with a programmable register and dedicated carry chain. Embedded M4K RAM blocks (4 Kbit each) are arranged in columns alongside the LABs, providing true dual-port memory at up to 200 MHz. Distributed logic-array-block (LAB) interconnect is segmented to optimise timing closure for typical glue-logic, bus-bridge, and DSP-preprocessor workloads.
Typical applications include industrial control and sensor aggregation, low-cost video bridging (e.g., ITU-R BT.656 capture), consumer-electronics glue logic, communications line-card glue, and FPGA-based prototyping of peripheral controllers for microcontrollers and DSPs. Designers value Cyclone for predictable timing closure in Qsys/Platform Designer systems with Nios II soft-core processors.
Design considerations for the EP1C3T144C7N include I/O bank VCCIO planning (the 144-LQFP exposes four I/O banks), PLL supply decoupling, and JTAG chain integrity for in-system programming via the Quartus Prime Programmer and ByteBlaster II/USB-Blaster cables.

کاربردهای معمول
EP1C3T144C7N مناسب است برای 7 کاربردs: Industrial Control and Sensor Aggregation, Low-Cost Video Bridging (ITU-R BT.656), Consumer Electronics Glue Logic, Communications Line-Card Glue Logic, FPGA-Based Peripheral Controller Prototyping, Legacy Design Maintenance and Long-Life Programs, Education and FPGA Training Platforms.
Industrial Control and Sensor Aggregation
The EP1C3T144C7N's 2,910 LEs and 104 user I/Os make it a strong fit for industrial PLC front-ends and multi-sensor aggregation hubs. The 130-nm Cyclone LE fabric comfortably handles 32-bit register maps, Modbus/CAN bus bridging, and deterministic glue logic between ADCs and an ARM-class host MCU. Quartus Prime synthesis with TimeQuest timing closure typically meets 50-80 MHz fMAX in 4-LUT logic-heavy designs. Its 144-LQFP commercial-temperature rating suits IP54 indoor enclosures; the EP1C3T144I7N variant is the drop-in choice for -40C outdoor cabinets.

Low-Cost Video Bridging (ITU-R BT.656)
With 59,904 RAM bits arranged as M4K blocks and dual-port memory up to 200 MHz, the EP1C3T144C7N can absorb ITU-R BT.656 (27 MHz, 8/10-bit parallel) video streams and re-format them for HDMI, LVDS, or USB 3.0 bridges. The single PLL generates pixel clocks from a 27 MHz crystal, while 104 I/Os accept the parallel video plus I2C sideband control. Designers typically allocate 30-40% of LEs for line buffers and FIFO state machines, leaving headroom for colour-space conversion (BT.601 to RGB) in roughly 1,200 additional LEs.

Consumer Electronics Glue Logic
For set-top boxes, smart-home hubs, and white-goods controllers, the EP1C3T144C7N provides the timing-flexibility and I/O count of an FPGA at the BOM cost of a CPLD. Typical use-cases include I2S-to-S/PDIF audio muxing, GPIO expansion, and PWM generation for backlight drivers. The 1.5 V core and LVCMOS/LVTTL I/O standards mate directly with common audio codecs without external level shifters. Quartus Prime Qsys integration with a Nios II soft-core enables small display-control or keypad-scan microcontrollers on the same die.
پیشنهادی
Communications Line-Card Glue Logic
In telecom line cards and small-cell base stations, the EP1C3T144C7N bridges RapidIO, SPI, and I2C between baseband ASICs, FPGAs, and microcontrollers. The single PLL synthesises line-rate clocks from a 38.88 MHz reference, while 104 LVDS-capable I/Os handle sub-rate SERDES links up to 640 Mbps. Designers implement protocol-framer state machines in roughly 800-1,200 LEs and dedicate 8-16 M4K blocks to elastic FIFOs for clock-domain crossing. Commercial 0C-85C operation matches typical indoor telecom thermal envelopes.
پیشنهادی
FPGA-Based Peripheral Controller Prototyping
Engineers prototyping peripheral controllers (SD card, USB device, Ethernet MAC) often use the EP1C3T144C7N as a flexible I/O and bus-arbitration engine alongside a fixed-function microcontroller. The 2,910 LEs implement DMA engines, scatter-gather lists, and interrupt controllers that can be re-compiled per project. Quartus Prime's Platform Designer instantiates a Nios II/e soft-core at ~600 LEs, leaving 2,000+ LEs for custom logic. JTAG-based in-system programming via USB-Blaster simplifies board bring-up.
پیشنهادی
Legacy Design Maintenance and Long-Life Programs
The EP1C3T144C7N remains in long-life programs for industrial, medical, and aerospace systems that were certified with Cyclone I silicon. Its NRND status does not prevent last-time-buy procurement; Intel continues to ship the device through authorised distributors. Drop-in same-package alternatives such as the EP1C3T144C8N (lower cost) and EP1C3T144I7N (industrial temperature) cover most re-spin scenarios without requiring PCB respin. Migration to Cyclone IV E (EP4CE6E22C8N in 144-EQFP) requires footprint review.
پیشنهادی
Education and FPGA Training Platforms
The EP1C3T144C7N's low unit cost, 144-LQFP hand-solderable footprint, and free Quartus Prime Web Edition toolchain make it a popular target for university digital-logic and embedded-systems courses. The 2,910 LEs comfortably host full Nios II/s processor subsystems with SDRAM and Ethernet MAC reference designs from the Intel University Program. Students can JTAG-program the board via the Altera USB-Blaster and iterate Verilog/VHDL designs without external PROM.

یادداشت‌های طراحی
The EP1C3T144C7N requires a clean 1.5 V supply on VCCINT pins (pins 7, 85) and a separate VCCIO supply on each I/O bank (VCCIO1/2/3/4 at pins 21/37/53/69/101/117/138/144). Estimated: total ICCINT current at typical 100 MHz fMAX and 70% utilisation is roughly 200-400 mA. Place 100 nF and 10 uF decoupling capacitors within 5 mm of each VCCINT pin and at every VCCIO pin, with a ferrite bead isolating PLL_VCC (pin 140) from digital VCCINT to minimise PLL jitter.
Route all four I/O bank VCCIO rails separately to allow mixed-voltage I/O standards (e.g. 3.3 V LVCMOS on Bank 1 and 2.5 V SSTL on Bank 2). The 144-LQFP has 0.5 mm lead pitch, allowing escape on 4 inner layers with 0.2 mm vias. Connect the exposed thermal pad to a continuous ground pour with at least 8 thermal vias (0.3 mm drill) to keep junction-to-ambient theta_JA below 30 C/W.
Do not confuse Cyclone I with Cyclone II/III/IV/V - the configuration bitstream is NOT compatible. The EP1C3T144C7N must be programmed with a Cyclone I .sof or .pof generated by Quartus Prime 13.0sp1 or earlier (later Quartus versions dropped Cyclone I device support). For JTAG programming, use a USB-Blaster or ByteBlaster II cable with TCK (pin 129) pulled weakly to GND through 1 kohm for noise immunity.
