EP1C6T144I6N Обзор

The Altera (now Intel Programmable Solutions Group) EP1C6T144I6N is a member of the first-generation Cyclone FPGA family, delivering 5,980 logic elements in a 144-pin Thin Quad Flat Pack (TQFP) package. It is fabricated on a 1.5V, 130 nm CMOS process, operates at an internal core clock up to 405.2 MHz, and is targeted at cost-sensitive, high-volume digital logic designs that previously used discrete gate arrays or CPLDs. The 'I6' speed/temperature grade indicates an industrial temperature range (-40 C to +100 C) with a -6 speed bin, while the 'N' suffix indicates a lead-free, RoHS-compliant assembly.

A field-programmable gate array (FPGA) is a semiconductor integrated circuit that can be configured by the customer after manufacture to implement arbitrary digital logic. The Cyclone family sits in the taxonomy: FPGA -> programmable logic device (PLD) -> digital logic IC -> semiconductor. FPGAs bridge the gap between fixed-function ASICs (low unit cost, no flexibility) and microcontrollers (flexible, but limited performance for parallel workloads). Cyclone devices contain an array of configurable logic blocks (LABs), embedded memory (M4K blocks), phase-locked loops (PLLs), and programmable I/O, all interconnected by a programmable routing fabric.

Key features of the EP1C6T144I6N include approximately 5,980 logic elements, around 90 Kbits of embedded RAM (M4K blocks), two PLLs for clock multiplication and phase shifting, and 100+ user I/O pins. The device supports a wide range of I/O standards including LVTTL, LVCMOS, PCI, SSTL, and LVDS, making it interoperable with common microprocessors, memories, and bus interfaces. Configuration is typically loaded from an external EPC serial configuration device or via JTAG, enabling in-system reprogrammability for field upgrades.

The Cyclone architecture uses a 1.5V core with separate VCCIO banks that can be powered at 1.5V, 1.8V, 2.5V, or 3.3V to interface with mixed-voltage peripherals. Its built-in multipliers and dedicated routing make it well suited to DSP-style data paths, while the abundant M4K blocks provide efficient on-chip buffering for FIFOs, lookup tables, and small frame stores.

Typical applications include industrial control and machine vision glue logic, motor control co-processors, low-cost software-defined radio front-end controllers, communication bridges (UART/SPI/I2C aggregation), LED video wall scan-and-refresh drivers, and education/hobby digital design platforms. The 144-TQFP package has generous pitch (0.5 mm) that is friendly to hand-soldering and four-layer prototype boards.

When designing with this part, plan for a stable 1.5V core supply, a separate VCCIO rail per bank, and a configuration mode (AS, PS, JTAG). Decouple every VCC/VCCIO pin with 0.1 uF and 10 uF bulk capacitors placed as close to the package as possible. The Cyclone handbook (Altera Cyclone Device Handbook) provides reference schematics and Quartus II pinout files for the 144-pin TQFP.

This page synthesizes distributor availability, drop-in same-package alternatives within the Cyclone family, and practical design notes not found in the manufacturer datasheet, helping engineers quickly evaluate the EP1C6T144I6N for both new designs and legacy board re-spins.

Типичное применение

EP1C6T144I6N подходит для 6 применениеs: Industrial Control & PLC Logic, Motor Control Co-Processor, Communication Bridge & Protocol Aggregator, LED Video Wall Scan & Refresh Driver, Software-Defined Radio Front-End Controller, Education & Hobby Digital Design Platform.

🏭

Industrial Control & PLC Logic

The EP1C6T144I6N fits industrial control and small PLC designs because its industrial -40 C to +100 C temperature range handles factory-floor thermal swings, while 5,980 logic elements are enough for ladder-logic-equivalent state machines, PID loops, and PWM generators. The two on-chip PLLs synthesize precise servo and motor-drive clocks from a low-cost crystal, and the LVDS-capable I/O bank interfaces to noise-immune industrial sensor buses without external transceivers. Use it to consolidate discrete 74-series glue logic and replace aging CPLDs with more headroom.

🏭

Motor Control Co-Processor

For multi-axis motor control co-processing, the EP1C6T144I6N delivers 5,980 logic elements capable of running several independent field-oriented-control (FOC) state machines in parallel, offloading the host MCU. Its 20 M4K memory blocks provide deterministic cycle buffers for current and speed feedback, and two PLLs generate the high-resolution PWM carrier and quadrature-encoder sample clocks. The 144-TQFP package exposes enough user I/O to drive 6-8 half-bridges via external gate drivers, with margin for encoder, Hall-sensor, and CAN-style feedback lines.

🌐

Communication Bridge & Protocol Aggregator

The EP1C6T144I6N excels as a protocol-aggregation bridge that fans out UART, SPI, I2C, and parallel buses to a host processor, because its 100+ I/O pins map easily to multi-drop sensor arrays and the 5,980 logic elements implement hardware FIFOs and CRC engines without CPU intervention. LVDS I/O support enables robust differential signalling across noisy backplanes up to several metres, while the 405.2 MHz internal fabric sustains multi-megabit serial streams. Industrial temperature grade allows deployment in outdoor enclosures, rack-mounted base stations, and vehicle gateways.

💡

LED Video Wall Scan & Refresh Driver

For LED video walls the EP1C6T144I6N's M4K memory blocks act as dual-port line buffers holding scan data while the previous frame is being shifted out, while the 5,980 logic elements implement gamma correction, refresh scheduling, and brightness modulation in parallel. Up to 100 user I/O pins drive several high-speed shift-register chains of LEDs simultaneously, and the PLLs synthesize the precise pixel clock from any standard video reference. Industrial temperature grade allows the controller to live inside the display cabinet without active cooling.

📻

Software-Defined Radio Front-End Controller

The EP1C6T144I6N is well-matched to SDR front-end controllers because its 5,980 logic elements implement CIC and FIR decimation filters, gain control loops, and IQ imbalance correction at baseband sample rates up to 80-100 MSPS. Two PLLs generate the ADC sampling clock and a phase-aligned LO offset, while LVDS pairs deliver parallel ADC data into the fabric without skew. The 144-TQFP footprint is hand-solderable on 4-layer prototype boards, accelerating experimental radio design cycles.

🧩

Education & Hobby Digital Design Platform

The EP1C6T144I6N is ideal for university and hobbyist digital design courses because the 144-pin TQFP at 0.5 mm pitch is friendlier than BGA for hand-soldering and rework, while the 5,980 logic elements fit typical class projects (RISC CPUs, graphics pipelines, signal processors). It is fully supported by the free Quartus II / Quartus Prime Web Edition toolchain, enabling students to learn VHDL/Verilog without licence cost. Industrial temperature tolerance and lead-free assembly mean lab boards survive handling and reflow practice.

What is the EP1C6T144I6N and what does the suffix code mean?
The EP1C6T144I6N is a first-generation Altera Cyclone FPGA in a 144-pin TQFP package, providing 5,980 logic elements on a 130 nm, 1.5V process. The suffix breaks down as: 'EP1C6' = Cyclone family, 6K logic elements; 'T144' = TQFP-144 package; 'I6' = Industrial temperature range with -6 speed grade; 'N' = lead-free, RoHS-compliant assembly. It operates with a core clock up to 405.2 MHz per the manufacturer datasheet.
What is the operating temperature range of EP1C6T144I6N?
The EP1C6T144I6N is specified for an industrial temperature range of -40 C to +100 C junction temperature, denoted by the 'I' in the suffix code. This makes it suitable for industrial, automotive interior, and outdoor equipment applications. For commercial (0 C to +85 C) versions, look at the EP1C6T144C6N variant instead.
How many user I/O pins does EP1C6T144I6N have?
The EP1C6T144I6N exposes roughly 100 user I/O pins across four I/O banks in the 144-pin TQFP package. The exact count depends on the I/O standard and bank voltage configuration; Quartus II pin planning reports the precise count after compilation. The package reserves pins for JTAG (TCK, TMS, TDI, TDO), configuration (MSEL, nCE, nCONFIG, nSTATUS, CONF_DONE), clock (CLK0/1/2/3), and PLL supplies.
Where can I buy EP1C6T144I6N and what is the lead time?
As of 2026-09-06, the EP1C6T144I6N is in last-time-buy status from Intel/Altera, so authorized distributors carry very limited stock. Independent distributors such as Octopart, Avnet, and brokers list the part at premium pricing in the USD 17-30 range. Lead time from authorized channels is generally 12-20 weeks for last-time-buy orders; obsolete/EOL stock prices climb sharply above that window.
What is the price of EP1C6T144I6N in production quantities?
As of 2026-09-06, distributor pricing on Octopart places the EP1C6T144I6N at roughly USD 28.50 at qty 1, USD 22.10 at qty 100, and USD 17.60 at qty 1000 in the broker/independent channel. Because the part is in last-time-buy, expect price volatility and minimum-order-quantity constraints; consider migrating to Cyclone II or Cyclone IV E equivalents for new designs.
Is EP1C6T144I6N still in production or obsolete?
The EP1C6T144I6N is in last-time-buy (LTB) status per the Altera/Intel Product Discontinuance notices; orders are accepted through a final deadline and the part will subsequently be classified obsolete. Customers with active designs should place last-time-buy orders now or migrate to Cyclone II EP2C6T144 or Cyclone IV E EP4CE6E22 devices in similar packages.
What is a drop-in replacement for EP1C6T144I6N?
Drop-in same-package alternatives for the EP1C6T144I6N are limited to other Cyclone family members in the same TQFP-144 footprint, namely the EP1C6T144C6N (commercial temp, -6 speed grade) and the EP1C6T144C7N / EP1C6T144C8N for higher speed bins. All share the same 144-pin TQFP package and identical pinout, allowing direct board swap with no PCB rework. Cross-brand true drop-ins do not exist because the Cyclone bitstream is Altera-proprietary.
Where to download EP1C6T144I6N datasheet PDF?
The Altera/Intel Cyclone Device Handbook (Cyclone Family datasheet) is the primary datasheet for the EP1C6T144I6N; download it from https://www.intel.com/content/www/us/en/programmable/documentation/lit-cyc/lit-cyclone.html. For pinout specifics, refer to the Cyclone Pin-Out File for the TQFP-144 package, distributed with Quartus II design software. Third-party archives such as Alldatasheet and Datasheets.com also host PDF copies.
What is the pinout of EP1C6T144I6N?
The EP1C6T144I6N uses a 144-pin TQFP package with 0.5 mm pin pitch and a 22 mm x 22 mm body. The complete pin assignment - including dedicated JTAG (TCK, TMS, TDI, TDO), configuration (MSEL[2:0], nCE, nCONFIG, nSTATUS, CONF_DONE), clock inputs (CLK0-CLK3), PLL analog supplies, and 100+ user I/O across four banks - is documented in the Cyclone Device Handbook Pin Information chapter and the Quartus II pinout file.
EP1C6T144I6N vs EP1C6T144C6N - which is better?
The EP1C6T144I6N is specified for industrial temperature range (-40 C to +100 C) while the EP1C6T144C6N targets commercial (0 C to +85 C). Both share the same -6 speed grade, identical 144-pin TQFP package, and same 5,980 logic element die, so they are fully pin-compatible drop-ins.

EP1C6T144I6N vs EP2C6T144C6N (Cyclone II) - is Cyclone II a drop-in upgrade?
The EP2C6T144C6N (Cyclone II) is a pin-compatible upgrade for the EP1C6T144I6N: same 144-pin TQFP package, same Quartus II toolchain, but built on a 90 nm process with 6K logic elements and more M4K memory. However, Cyclone II is NOT a true drop-in because the I/O bank structure and core voltage differ (Cyclone II uses 1.2V core), so existing 1.5V rails must be redesigned. Use it for new designs, not legacy board rework.
What is the best Altera equivalent for EP1C6T144I6N?
The best same-brand same-package equivalent for the EP1C6T144I6N is the EP1C6T144C6N (commercial temperature, identical -6 speed grade) for a true drop-in. For a higher-performance replacement in the same TQFP-144 footprint, use the EP1C6T144C8N (-8 speed grade) which is the fastest Cyclone silicon. For new designs the recommended modern migration is the Cyclone IV E family in TQFP-144 or EQFP-144 packages, supported by current Quartus Prime.
Can EP1C6T144I6N be used for industrial control applications?
Yes, the EP1C6T144I6N is well-suited for industrial control applications thanks to its industrial -40 C to +100 C temperature range, 5,980 logic elements for glue logic and state machines, two PLLs for precise motor and servo timing, and LVDS support for noise-immune communication to industrial sensors. The 144-pin TQFP package is hand-solderable, simplifying prototype assembly. For harsher environments with sustained high vibration, use the EP1C6F256I6N ball-grid-array package instead.
What are the key specifications of EP1C6T144I6N that engineers should know?
The key EP1C6T144I6N specifications are: 5,980 logic elements, 130 nm process, 1.5V core supply, 405.2 MHz maximum internal frequency, 144-pin TQFP package, 100+ user I/O across four banks, 20 M4K memory blocks (approximately 92 Kbits total), 2 PLLs, support for LVTTL/LVCMOS/PCI/SSTL/LVDS I/O standards, JTAG and AS/PS configuration, industrial -40 C to +100 C operating temperature, and lead-free RoHS assembly. The part is in last-time-buy status as of 2026-09-06.

Руководство по выбору

Choose the EP1C6T144I6N when designing industrial-grade Cyclone FPGA systems that must operate from -40 C to +100 C and require RoHS-compliant assembly. For new designs, prefer the EP1C6T144C7N (faster -7 speed grade, same package) for timing margin headroom, or migrate to Cyclone IV E EP4CE6E22 for long-term supply continuity. The EP1C6T144I6N remains the right choice for legacy board re-spins, repair, and last-time-buy stockpile of proven designs where exact silicon identity matters.

Заметки по проектированию

Estimated power budget for a 50%-utilization Cyclone design at 100 MHz: roughly 0.5-1.0 W from VCCINT (1.5V) plus I/O current of 10-20 mA per bank at 3.3V LVTTL. Place one 0.1 uF ceramic decoupling cap adjacent to every VCCINT, VCCIO, and PLL analog supply pin, and add two to four 47-100 uF bulk aluminium-polymer or tantalum capacitors near the package. Power-on sequence: VCCINT must reach 1.5V before VCCIO banks to avoid I/O latch-up; use a supervisor IC or sequenced LDO pair. Estimated input current at 1.5V x 0.6 A = 0.9 W typical.

Route JTAG (TCK, TMS, TDI, TDO) and configuration pins (MSEL, nCE, nCONFIG, nSTATUS, CONF_DONE) as short, parallel traces no longer than 50 mm to avoid signal-integrity issues; add 4.7 kohm pull-ups on nCE, nCONFIG, and CONF_DONE to VCCIO. Keep differential pair (LVDS) lengths matched within 0.5 mm. Provide a 4-layer stack-up with continuous ground plane under the TQFP-144 footprint and stitch vias every 5 mm along the perimeter. The TQFP-144 thermal pad (exposed pad, if present in the package variant) must be soldered to a ground-copper pour 10-10 mm minimum for heat spreading.

Do not leave configuration mode pins MSEL floating - tie them high or low to select AS (active serial, MSEL[2:0]=000), PS (passive serial, MSEL[2:0]=100), or JTAG-only (MSEL[2:0]=101) configuration. The nCONFIG pin must see a clean rising edge at power-up or the device will not configure; debounce any mechanical reset pushbutton with a 100 nF cap. Mixing 3.3V and 1.5V on the same I/O bank is illegal - group pins by voltage into the four VCCIO banks before PCB layout.
