EP1C6T144C6N Visão geral

The Intel (formerly Altera) EP1C6T144C6N is a low-cost Cyclone FPGA from the Cyclone family, delivering 5,980 logic elements, 92,160 bits of embedded RAM, and 98 user I/O pins in a 144-pin TQFP (T144) package with a -6 speed grade and commercial 0C to 85C operating range. The device integrates a 1.5V core, two PLLs, and a 405.2 MHz maximum internal operating frequency, targeting cost-sensitive high-volume applications.

A Field Programmable Gate Array (FPGA) is a reconfigurable integrated circuit built from an array of programmable logic blocks, interconnect, and I/O cells that can implement custom digital logic after PCB assembly. FPGAs sit in the programmable logic device hierarchy between fixed-function ASICs and CPLDs, combining the high integration of ASICs with the flexibility of post-fabrication reconfiguration. The Cyclone family specifically occupies the low-power, low-cost node of Intel's FPGA portfolio, optimized for glue logic, parallel processing, and interface bridging.

Key features of the EP1C6T144C6N include 5,980 logic elements, 92,160 RAM bits distributed in M4K blocks, two PLLs for clock management, 98 maximum user I/O pins arranged as eight I/O banks, and support for LVTTL, LVCMOS, PCI, SSTL-2, and SSTL-3 I/O standards. The 1.5V core and 144-pin TQFP (22 mm x 22 mm body, 0.5 mm pitch) footprint keep board-level integration simple for legacy through-hole-style PCB manufacturing flows.

The device is fabricated on a 0.13-micron SRAM-based process, which makes the configuration volatile and requires an external configuration device (typically an EPCS1 or EPCS4 serial flash) to load the bitstream at power-up. The Cyclone architecture combines 4-input look-up tables (LUTs), embedded memory, and DSP-friendly multiplier blocks, making the EP1C6 well suited to digital signal processing, custom bus interfaces, and industrial control applications where deterministic parallel logic outperforms microcontrollers.

Typical applications include industrial automation controllers, video processing and image aggregation, consumer electronics glue logic, communications protocol bridging (UART, SPI, I2C, Ethernet MAC front-ends), and legacy ASIC replacement. The Cyclone EP1C6 is widely used in 32-bit RISC soft-core implementations (Nios II) and in parallel sensor aggregation hubs for camera and machine-vision front ends.

When designing with the EP1C6T144C6N, allocate a configuration flash device (EPCS1/EPCS4) on the JTAG-friendly 4-wire serial bus (nCONFIG, nSTATUS, CONF_DONE, DCLK) and reserve at least four pins for the JTAG chain. Decouple VCCINT (1.5V) and VCCIO (1.5V/1.8V/2.5V/3.3V) rails with bulk plus high-frequency ceramic capacitors placed as close to the pins as the TQFP allows.

🏭

Industrial Automation Controllers

The EP1C6T144C6N fits industrial automation controllers that need deterministic parallel logic, multiple communication interfaces, and customizable I/O timing. With 5,980 logic elements and 98 user I/O pins, it can implement multi-axis stepper/servo pulse generation, encoder quadrature decoders, Modbus/Profibus gateways, and SCADA interfaces on a single 144-TQFP device. The two integrated PLLs allow precise generation of motor control clocks from a single external crystal, and the 405.2 MHz internal frequency headroom supports tight control loops. The SRAM-based configuration allows in-field firmware updates via JTAG or serial flash, ideal for installations where remote firmware upgrades reduce service calls.

Video and Image Aggregation

The EP1C6T144C6N is well matched to video processing front-ends that aggregate parallel sensor data and perform lightweight pixel processing. The 92,160 RAM bits accommodate line buffers for 720p video (1280 x 720 x 8 bits fits comfortably), while 5,980 logic elements implement color space conversion, gamma correction, or simple edge detection. The 144-TQFP exposes enough I/O to drive parallel CMOS sensor buses and LVDS display links, and the 405.2 MHz timing headroom lets designers meet pixel clock rates of 148.5 MHz (1080p) at -6 speed grade. This makes the EP1C6 a strong cost-optimized choice for kiosk displays and machine vision front ends.

🔧

Legacy ASIC Replacement

The EP1C6T144C6N is a preferred drop-in for obsolete ASICs in fielded industrial and military systems where re-spinning a mask set is cost-prohibitive. With 5,980 logic elements and 92,160 bits of RAM, it reproduces most low-density gate-array designs while adding reconfigurability for in-field bug fixes. The 144-TQFP footprint and JTAG-based configuration align with the legacy ASIC socket pads, allowing PCB-level replacement without re-routing. Engineers can preserve the original schematic and BOM by re-implementing the netlist in VHDL or Verilog and programming the Cyclone bitstream through a standard EPCS1 serial flash, drastically reducing end-of-life redesign risk.

Soft-Core Processor Implementation (Nios II)

The EP1C6T144C6N is a well-known platform for embedding the Nios II 32-bit RISC soft-core, which uses roughly 600-1,800 logic elements depending on the variant. This leaves the remaining logic elements for peripheral timers, UARTs, SPI controllers, and custom accelerators, while 92,160 bits of embedded RAM serve as data and instruction cache. The two PLLs generate CPU clocks from external crystals and peripheral clocks from a single reference, and the 98 user I/O pins map to parallel memory and external peripherals. For education, prototyping, and low-volume embedded systems, the EP1C6 delivers a programmable 32-bit platform at FPGA unit cost.

Due to NCNR status, lead times at the manufacturer are no longer supported, so only distributor inventory applies.

Is EP1C6T144C6N in stock right now?

Yes, as of 2026-09-06 Heisener reports in stock and DigiKey lists the part as active for purchase. Because the device is NCNR, future stock is uncertain - secure volume orders with second-source options identified before committing to new PCB runs.

EP1C6T144C6N vs EP1C6F256C8N - which is better for high I/O designs?

The EP1C6F256C8N uses a 256-pin FBGA package offering more I/O pins than the EP1C6T144C6N's 144-pin TQFP, but both share the same 5,980 logic elements and 92,160 RAM bits. Choose EP1C6T144C6N for legacy TQFP-friendly PCBs (98 user I/O); choose EP1C6F256C8N for new designs needing >98 I/O or higher density routing.

EP1C6T144C6N vs EP1C6T144C8N - what is the speed difference?

The EP1C6T144C6N is a -6 speed grade device while EP1C6T144C8N is a -8 (faster) speed grade. Per Altera's speed-grade convention, lower numbers indicate slower timing, so the C8 variant supports higher internal frequencies than the C6. Both share the same 144-TQFP footprint, making them drop-in substitutes with timing improvements.

When should I choose EP1C6T144C6N over Cyclone IV EP4CE6?

Choose EP1C6T144C6N when maintaining a legacy design, repairing existing inventory, or supporting a product line that is already in production. For new designs, the Cyclone IV EP4CE6E22C8N offers lower static power, a more modern Quartus toolchain, and longer-term lifecycle support on the same 144-EQFP footprint family.

Is EP1C6T144C6N suitable for new industrial designs?

The EP1C6T144C6N is suitable only when reusing proven hardware IP or maintaining field-deployed systems. For new industrial designs in 2026, Intel's Cyclone IV E (EP4CE6) or Cyclone 10 LP (10CL006YU256C8G) provide longer lifecycle support, lower power, and active toolchain maintenance in the Quartus Prime environment.

What is the best drop-in replacement for EP1C6T144C6N?

The closest pin-compatible drop-in replacements are EP1C6T144C8N (same 144-TQFP, faster speed grade) and EP1C6T144I7N (industrial temperature range). For modern designs, EP4CE6E22C8N (Cyclone IV E) and 10CL006YU256C8G (Cyclone 10 LP) offer forward-compatible drop-in replacements in the EQFP family, though footprint migration may be required.

What are the key specifications of EP1C6T144C6N engineers should know?

The EP1C6T144C6N has 5,980 logic elements, 92,160 RAM bits, 98 user I/O, two PLLs, a 1.5V core, 405.2 MHz maximum internal frequency, 144-TQFP package, commercial 0C-85C range, -6 speed grade, and uses an SRAM-based configuration requiring an external serial flash. Per Altera Cyclone Family Data Sheet, it targets cost-sensitive volume applications.

Is EP1C6T144C6N the same as EP1C6T144C8N?

No, EP1C6T144C6N and EP1C6T144C8N differ in speed grade (-6 vs -8). Per FindIC's parametric comparison, the C8 variant supports higher internal frequencies with identical logic resources, package, and pinout. They share the same 144-TQFP footprint and are pin-to-pin compatible drop-in substitutes, with the C8 providing faster timing closure.

What is the best Lattice Semiconductor equivalent for EP1C6T144C6N?

Per cross-brand web data, Lattice Semiconductor's XP2-6E TQFP144 and ECP2-6 TQFP144 in the same 144-TQFP class provide comparable logic density (approximately 6,000 LUTs) with the Lattice Diamond/ispLEVER toolchain. Footprint compatibility must be verified against the specific XP2 part number before PCB drop-in replacement.

Can EP4CE6E22C8N replace EP1C6T144C6N without PCB rework?

The EP4CE6E22C8N (Cyclone IV E) is a drop-in upgrade candidate but uses a 144-pin EQFP package with a different lead pitch and exposed pad. It is NOT a true pin-to-pin drop-in replacement for the EP1C6T144C6N's 144-TQFP. For PCB reuse, prefer the Cyclone IV E EP4CE6T144C8N variant in the 144-TQFP-equivalent package.

Guia de seleção

Choose the EP1C6T144C6N for legacy designs, fielded systems, and maintenance applications where the existing PCB uses a 144-TQFP footprint and toolchain is locked to the Altera Quartus II Web Edition flow. For new industrial designs in 2026, prefer the Cyclone IV E EP4CE6E22C8N or Cyclone 10 LP 10CL006YU256C8G to gain longer lifecycle, lower power, and active Quartus Prime support. Choose EP1C6T144C8N when you need faster timing closure on the same footprint, and EP1C6T144I7N for industrial temperature deployments. Avoid the EP1C3 family unless you genuinely need only ~2,900 logic elements and want to free up unit cost.

Notas de projeto

The EP1C6T144C6N requires a clean 1.5V core supply (VCCINT) plus per-bank VCCIO rails. Estimate dynamic current roughly at ICCINT ~= 0.5-1 mA per MHz times utilization, plus I/O current scaled by toggle rate. Place at least one 100 uF bulk plus four 0.1 uF high-frequency ceramics near the TQFP pins. Each PLL needs an isolated VCC_PLL filter (ferrite bead + 10 uF + 0.1 uF) per Altera's Cyclone PowerPlay guidance.

Although the 144-TQFP is a plastic package with 0.5 mm lead pitch, route differential pairs and clock nets on the top layer with a continuous ground plane beneath. Use 8-12 mil traces between TQFP pads and vias-in-pad for clean escapes. Keep JTAG signals (TCK, TMS, TDI, TDO, nCONFIG, nSTATUS, CONF_DONE, DCLK) on dedicated short routes; loop-through is mandatory for multi-device chains.

Estimated: total power with all 5,980 LEs at 50% toggle rate and 100 MHz clock approximates 0.5-1 W. With TQFP thermal resistance around 35 C/W theta_JA on a 4-layer JEDEC board, junction temperature rises 18-35 C above ambient. Always simulate with Quartus PowerPlay before locking the BOM. Failure to include an external configuration device (EPCS1/EPCS4) causes the FPGA to remain in reset at power-up.
