EP1C6T144C8N 概述

The Intel (formerly Altera) EP1C6T144C8N is a low-cost Cyclone® Field Programmable Gate Array (FPGA) delivering 5,980 logic elements, 92,160 bits of embedded RAM, and 98 user I/O pins in a 144-pin TQFP package with a commercial 0°C to +85°C operating range. The device is built on a 1.5 V, 0.13 µm all-layer copper SRAM process and is offered in the -C8 speed grade targeting up to 275 MHz internal operation, making it a long-standing workhorse for cost-sensitive digital designs, glue logic, and legacy industrial platforms.

An FPGA (Field Programmable Gate Array) is a reprogrammable semiconductor that lets engineers implement arbitrary digital logic - from simple state machines to soft processor cores - by configuring an on-chip array of look-up tables, flip-flops, and programmable interconnect. FPGAs sit in the broader taxonomy of programmable logic devices (PLD), above simple CPLDs in capacity and below ASICs in per-unit cost but with the crucial advantage of in-system reprogrammability. The Cyclone family specifically targeted low power and low cost per logic element, opening FPGAs to volume consumer and industrial markets previously served only by ASICs or microcontroller-based designs.

Key features of the EP1C6T144C8N include two PLLs for clock multiplication and phase shifting, dedicated 18x18 multipliers for DSP-style arithmetic, support for external memory interfaces including DDR SDRAM and FCRAM, and an active serial (AS) configuration interface compatible with low-cost EPCS configuration devices. The 144-TQFP package provides 98 usable I/O pins arranged in four I/O banks, allowing flexible mixed-voltage interfacing through bank-level VCCIO rails.

Typical applications include industrial control and factory automation backplanes, motor control and inverter drive boards, telecommunications line cards and protocol bridges, low-cost video processing pipelines, education and development kits, and replacement of legacy glue-logic ASICs where the original mask set is unavailable. Long product-life status and broad Quartus II tool support have made it a default choice for sustaining engineering.

When designing with the EP1C6T144C8N, engineers should plan for a 1.5 V core supply with separate VCCIO bank rails and observe the I/O bank voltage grouping rules documented in the Cyclone device handbook. Configuration memory must be loaded at every power-up from a non-volatile EPCS device or a JTAG/USB-Blaster programmer; the device does not retain configuration when powered down. Thermal management is straightforward thanks to the plastic TQFP package and modest static plus dynamic power dissipation.

This page synthesizes Cyclone family datasheet parameters, distributor stock and pricing snapshots, and drop-in same-footprint alternatives (C6/C7 speed grades, I-grade temperature variants, and 144-TQFP Cyclone I siblings) to help engineers compare, source, and sustain EP1C6T144C8N-based designs.

典型应用

EP1C6T144C8N 适用于 6 应用s: Industrial Motor Control, Telecommunications Line Cards and Protocol Bridges, Legacy Glue-Logic and ASIC Replacement, Education and FPGA Training Platforms, Low-Cost Video Processing Pipelines, Data Acquisition Front-Ends.

🏭

Industrial Motor Control

The EP1C6T144C8N fits industrial motor-control boards because its 5,980 logic elements, 2 PLLs, and 92 Kbits of embedded RAM provide enough capacity to host encoder decoding (QEP), PWM generation, and current-loop state machines in a single chip. The 98 user I/Os comfortably connect to multi-axis power-stage gate drivers, Hall sensors, and isolated communication transceivers. The Cyclone I 0.13 µm process keeps static power low, an important factor in always-on factory cabinets.

🌐

Telecommunications Line Cards and Protocol Bridges

In telecom line-interface cards, the EP1C6T144C8N serves as a low-cost protocol-bridging FPGA, mapping between legacy T1/E1 framers, I²S audio buses, and Ethernet MII/RMII PHYs. Its 275 MHz core plus 2 PLLs can drive 100 Mbps MII comfortably, while the 98 I/Os handle multiple serial streams with hardware-accelerated framing. The commercial 0°C to +85°C range suits controlled-environment central-office deployments where industrial-grade parts are unnecessary.

🔧

Legacy Glue-Logic and ASIC Replacement

The EP1C6T144C8N is a workhorse replacement for aging 144-TQFP ASICs and discrete 74-series glue logic in long-life industrial platforms. Its SRAM-based configuration lets engineers re-spin functionality in software without respinning the silicon, dramatically reducing sustaining-engineering cost. The Cyclone I family's decade-long production history and Quartus II Web Edition free toolchain support mean designs can be maintained without expensive software licenses.

🧩

Education and FPGA Training Platforms

Universities and FPGA training labs favor the EP1C6T144C8N because its 5,980 logic elements are large enough to host a Nios II soft processor and meaningful student projects, yet small enough that Quartus II Web Edition (free) can compile bitstreams within minutes. The 144-TQFP package is breadboard-friendly with 0.5 mm pitch adaptors, and the abundant EP1C6 development kit reference designs accelerate student onboarding. Long product-life assurance also lets universities stock lab kits with confidence.

📺

Low-Cost Video Processing Pipelines

The EP1C6T144C8N supports entry-level video processing such as NTSC/PAL decoding, on-screen-display overlay, and color-space conversion in cost-sensitive consumer equipment. Its 98 I/Os accommodate parallel ITU-R BT.601 video buses plus control peripherals, and the 92 Kbits of block RAM buffer line-store memory without external SRAM. The 1.5 V core with 3.3 V-tolerant I/Os makes it easy to interface directly to legacy video ADCs and DACs.

🖥️

Data Acquisition Front-Ends

The EP1C6T144C8N is a strong fit for multi-channel data-acquisition front-ends where it manages timing-critical ADC/DAC handshake logic, FIR filter pre-processing, and DMA transfers to a host MCU. The 2 PLLs generate multiple simultaneous sample clocks, while 92 Kbits of block RAM implement per-channel ping-pong buffers. The commercial temperature range suits benchtop and laboratory instruments, and the same PCB can host the EP1C6T144I7N industrial variant for field-deployed units.

What is the EP1C6T144C8N and what logic capacity does it provide?
The EP1C6T144C8N is an Intel (formerly Altera) Cyclone® I FPGA in a 144-pin TQFP package, providing 5,980 logic elements, 598 LABs, and 92,160 bits of embedded RAM. According to the Cyclone device handbook, this density targets low-cost, low-power designs requiring moderate logic and DSP capability. The -C8 speed grade and 98 user I/O pins make it suitable for glue logic, motor control, and industrial bridging applications.
What is the maximum operating frequency of the EP1C6T144C8N?
The EP1C6T144C8N operates up to 275 MHz internal frequency in the -C8 commercial speed grade, per the manufacturer datasheet. Designers should consult the Quartus II timing analyzer for path-specific fMAX figures, which depend on logic depth, routing, and I/O standard. The two on-chip PLLs support clock multiplication, division, and phase shifting for system-clock synthesis.
What is the difference between EP1C6T144C8N and EP1C6T144C6N?
Both are 144-TQFP Cyclone I devices with identical 5,980 logic elements and 98 I/Os, differing only in speed grade: the EP1C6T144C8N is -C8 (slower) and the EP1C6T144C6N is -C6 (faster, higher fMAX). They are pin-to-pin drop-in replacements; choose C6 when timing margin is tight and C8 when cost is the primary constraint. Both share identical VCCINT, VCCIO, and configuration pinouts.
What is the difference between EP1C6T144C8N and EP1C6T144I7N?
The EP1C6T144C8N is the commercial-temperature variant (0°C to +85°C, -C8 speed grade), while the EP1C6T144I7N is the industrial-temperature variant (-40°C to +100°C, -C7 speed grade) in the same 144-TQFP package. Both are drop-in pin-compatible on the same PCB footprint, allowing a single layout to serve either grade. The I-grade version is preferred for outdoor, automotive, or harsh-environment deployments.
How do I configure the EP1C6T144C8N at power-up?
The EP1C6T144C8N loads its SRAM configuration at every power-up via Active Serial (EPCS1/EPCS4/EPCS16) using the dedicated ASDO/nCSO/DATA pins, or through JTAG using a USB-Blaster download cable. According to the Cyclone handbook, the MSEL[2:0] pins select the configuration scheme. Configuration time depends on bitstream size (roughly 1.2 Mbit for this device) and the EPCS clock rate, typically under 100 ms.
What is the core voltage and I/O bank supply requirement?
The EP1C6T144C8N requires VCCINT of 1.425 V to 1.575 V (nominal 1.5 V) and four independent VCCIO rails that can each be set to 1.5 V, 1.8 V, 2.5 V, or 3.3 V depending on the I/O standard used in each bank. The Cyclone device handbook specifies that all four banks share I/O rules driven by VCCIO; mixing voltage standards between banks is supported as long as each bank is supplied correctly. A clean PLL analog supply (VCCA_PLL) of 1.5 V is also required.
Where can I buy EP1C6T144C8N and what is the current price?
The EP1C6T144C8N is in stock at major distributors including DigiKey and Mouser as of 2026-09-06, with secondary inventory at Heisener (147,480 pieces reported), Win Source, and Semiconductors-IC.com. Typical single-unit pricing is around $23.07 USD, dropping to roughly $12.95 at the 1,000-piece break. Lead time is generally immediate from franchised distributors for the commercial-temperature variant.
What is the lead time for EP1C6T144C8N orders?
The lead time for the EP1C6T144C8N is generally immediate from franchised distributors such as DigiKey and Mouser, both of which list the part as 'ships today' in 2026. According to distributor inventory data, Heisener reports more than in stock with same-day shipping available. For production volumes above 5,000 pieces, requesting a quote from the distributor is recommended to confirm factory allocation.
Which Altera / Intel Cyclone parts are drop-in replacements for EP1C6T144C8N?
Drop-in pin-compatible alternatives in the same 144-TQFP footprint include the EP1C6T144C7N (faster -C7 grade), EP1C6T144C6N (fastest -C6 grade), EP1C6T144I7N (industrial temperature, -C7), and EP1C3T144C8N (smaller 3,000-LE device with extra unused I/O). All share identical pinout, VCCINT/VCCIO requirements, and configuration pin assignments, so a single PCB layout supports the entire Cyclone I 144-TQFP family.
Is EP1C6T144C8N the same as EP1C6T144C8?
The EP1C6T144C8N and EP1C6T144C8 refer to the same Cyclone I FPGA die and 144-TQFP package, with the trailing 'N' indicating lead-free / Pb-free terminal finish. Functionally they are identical, but the lead-free 'N' suffix is required for RoHS-compliant assemblies. Both are drop-in interchangeable in modern SMT production lines; legacy non-RoHS boards can use either variant.
What design tools support EP1C6T144C8N development?

选型指南

Choose the EP1C6T144C8N when you need a low-cost Cyclone I FPGA with 5,980 logic elements, 98 user I/Os, and 1.5 V core in a 144-TQFP package for commercial-temperature (0°C to +85°C) applications. Switch to EP1C6T144C6N or EP1C6T144C7N if timing closure fails at the C8 speed grade - both are pin-compatible drop-ins. Choose EP1C6T144I7N for industrial-temperature (-40°C to +100°C) deployments such as outdoor or factory-floor equipment. For designs requiring fewer logic resources, step down to EP1C3T144C8N (3,000 LEs) in the same 144-TQFP footprint to reduce per-unit cost. For higher I/O count, migrate to EP1C6F256C8N (256-FBGA, 185 I/Os) or EP1C6Q240C8N (240-PQFP, 185 I/Os). All Cyclone I 144-TQFP variants share configuration pinout and power requirements, so a single PCB layout can serve multiple part numbers across the family.

关键差异点

  • Sweet-spot density between EP1C3 and EP1C12 in Cyclone I family (对比 EP1C3T144C8N)
  • Industrial-temperature drop-in available for harsh-environment designs (对比 EP1C6T144I7N)
  • Faster C6/C7 speed grades enable tighter timing margins (对比 EP1C6T144C6N)

设计说明

The EP1C6T144C8N requires a regulated 1.5 V VCCINT rail capable of supplying transient currents up to ~500 mA during configuration, plus four independent VCCIO rails (1.5 V / 1.8 V / 2.5 V / 3.3 V) for I/O banks. Decouple each VCCINT pin with a 0.1 µF X7R ceramic placed within 5 mm of the pin, and bulk-decouple each VCCIO bank with 10 µF tantalum plus 0.1 µF ceramic. The PLL analog supply (VCCA_PLL) should be filtered through a ferrite bead and decoupled with 10 µF + 0.1 µF to suppress jitter.

Route JTAG (TCK, TMS, TDI, TDO) as a daisy-chain with 22 Ω series-termination resistors near the driver; keep the chain stub length under 25 mm to preserve signal integrity. Place the EPCS configuration flash within 50 mm of the ASDO/nCSO/DATA pins and use a 4-layer PCB with continuous ground plane under the TQFP footprint. Leave a 2 mm copper keep-out around the TQFP body for inspection access, and flood unused I/O bank area with VCCIO for shielding.

Do not leave MSEL[2:0] floating; tie them through 10 kΩ resistors to the correct configuration-mode logic level (AS mode = 000, JTAG-only = 101). The CONF_DONE and nSTATUS pins are open-drain and require external 10 kΩ pull-ups to VCCIO. Avoid using the EP1C6T144C8N in new designs requiring >85°C ambient operation - select EP1C6T144I7N (industrial) instead. Configuration failures on first prototypes are most often due to missing VCCA_PLL decoupling or incorrect MSEL strapping.
