EP1C6TC144-8 Обзор

The Intel (formerly Altera) EP1C6TC144-8 is a member of the first-generation Cyclone FPGA family, integrating 5,980 logic elements, 92,160 RAM bits, and two PLLs in a 144-pin TQFP package. The '-8' suffix indicates the commercial speed grade with 8 ns pin-to-pin logic delay. According to the Cyclone Family Data Sheet, this device supports up to 185 user I/O across its package options and operates from a 1.5 V core supply with 3.3 V I/O tolerance through dedicated bank voltage rails.

An FPGA (Field-Programmable Gate Array) is a type of programmable logic device that allows designers to implement custom digital logic, state machines, DSP pipelines, and bus interfaces after PCB fabrication. FPGAs belong to the broader hierarchy of programmable logic -> ASIC prototyping devices -> digital semiconductor ICs. The Cyclone family is positioned as a low-cost, low-power FPGA family targeting high-volume applications such as consumer electronics, industrial control, and communications glue logic, sitting below Stratix devices in Altera's portfolio but above MAX CPLDs in logic density.

Key features of the EP1C6TC144-8 include 5,980 logic elements, 92,160 bits of embedded RAM organized as M4K blocks (4,608 bits each, 20 blocks total), 92 user I/O pins in this TQFP-144 package, two phase-locked loops for clock management, and support for LVTTL, LVCMOS, SSTL, and HSTL I/O standards. The device also features dedicated multiplier blocks capable of single 18x18 multiplication for DSP functions and supports external memory interfaces such as DDR SDRAM, QDR SRAM, and SDR SDRAM through dedicated interface circuitry.

The Cyclone architecture is built on a 1.5 V, 130 nm SRAM process with four-input look-up tables (LUTs) and embedded memory columns. Configuration is achieved through an SRAM-based bitstream loaded via JTAG, Active Serial (AS), or Passive Serial (PS) modes, with built-in decompression and CRC error detection. The 144-pin TQFP variant offers 92 user I/O pins with fine-grained LVDS support on selected pairs, making it suitable for cost-sensitive designs where BGA packages are not required.

Typical applications include industrial control and motor drives, consumer video processing, communications protocol bridging, low-cost DSP implementations, and PCI bus interfacing. The combination of low unit cost, mature tool support (Quartus II), and a non-BGA package makes the EP1C6TC144-8 well-suited for prototype runs, low-volume production, and through-hole-friendly board designs.

When designing with this device, plan for a 1.5 V core regulator with adequate transient response and a separate 3.3 V rail for the I/O banks. Power dissipation varies with logic utilization and toggle rate - estimate early using the PowerPlay analyzer in Quartus II. The Cyclone family has been marked EOL by Intel; for new designs, consider Cyclone II, Cyclone IV, or Cyclone V devices unless long-term continuity with legacy IP is required.

Типичное применение

EP1C6TC144-8 подходит для 6 применениеs: Industrial Motor Control, Consumer Video Processing, Communications Protocol Bridging, Low-Cost DSP Implementation, PCI Bus Interface Card, Legacy Design Continuity.

🏭

Industrial Motor Control

The EP1C6TC144-8 is well-suited for industrial motor control and drive signal generation. With 5,980 logic elements and 92 user I/Os in the 144-TQFP, the device can host multiple PWM channels, encoder interfaces, and field-oriented control (FOC) state machines while leaving headroom for serial protocol stacks such as RS-485 Modbus. The 92,160 bits of embedded M4K memory provide line buffers for current-loop sampling at typical 10 kHz rates. Designers appreciate the through-hole-friendly TQFP package, which simplifies prototype bring-up on 4-layer FR-4 boards used in motor drive PCBs. The -8 commercial speed grade is adequate for switching frequencies up to 100 kHz with proper pipeline scheduling. Estimated: 5,980 LEs at 50% utilization at 50 MHz toggle rate yields roughly 200-300 mW core power at 1.5 V.

Consumer Video Processing

Consumer video processing applications benefit from the EP1C6TC144-8's M4K memory blocks and PLL flexibility. The 92,160 bits of RAM support line buffers for video scaling, color-space conversion, and deinterlacing algorithms at standard-definition resolutions. Two PLLs provide independent clock generation for video pixel clocks and back-channel processing, eliminating the need for external clock generators on the PCB. The 144-TQFP package exposes 92 user I/Os, sufficient for 24-bit RGB buses, ITU-R BT.656 interfaces, and I2C control paths. The Cyclone architecture's 18x18 multiplier blocks can perform small filter taps for sharpening or noise reduction in real time. Estimated: a 720x480 deinterlacer using two line buffers consumes roughly 30 M4K blocks and 800 LEs, leaving room for on-screen display logic.

🌐

Communications Protocol Bridging

Protocol bridging between legacy and modern interfaces is a classic Cyclone use case. The EP1C6TC144-8 can simultaneously host UART, SPI, I2C, and PCI cores in the same fabric, providing glue-logic translation between, for example, an embedded host processor's SPI bus and a downstream CAN or RS-422 network. With 92 user I/Os, multiple parallel buses can be routed without external transceivers. The 1.5 V core and 3.3 V-tolerant I/O banks allow direct connection to legacy 5 V-tolerant PHYs through external resistively-clamped I/O. Designers can prototype in the 144-TQFP package on a through-hole-friendly PCB and migrate to the QFP-240 variant when more I/O is needed. Estimated: a quad-UART bridge plus PCI target core fits comfortably in 4,500 LEs and 40 M4K blocks.

Low-Cost DSP Implementation

Although the Cyclone family's embedded multipliers are less capable than modern DSP blocks, the EP1C6TC144-8 still performs well for low-cost DSP tasks such as FIR filtering, FFT pre/post-processing, and audio effects. The 18x18 multiplier capability supports single-cycle MAC operations, and with distributed arithmetic techniques the 5,980 LEs can implement 32-tap FIR filters with no external DSP chip. The two PLLs provide independent sample-rate conversion clocks, useful for audio interfaces that span from 8 kHz voice to 192 kHz hi-fi rates. The 144-TQFP package is compatible with hand-rework-friendly board assemblies, lowering prototype cost. Estimated: a 64-tap audio FIR at 48 kHz uses approximately 2,500 LEs and 16 M4K blocks for coefficient storage.

🖥️

PCI Bus Interface Card

The EP1C6TC144-8 includes dedicated 3.3 V PCI-compliant I/O buffers and supporting logic, making it a natural fit for low-cost PCI add-in cards. At 33 MHz, the -8 speed grade is fully PCI-compliant, and the 92 user I/Os in the 144-TQFP package provide ample room for the 32-bit PCI bus plus application-specific I/O such as opto-isolated digital inputs or serial peripherals. Designers can implement a 32-bit, 33 MHz PCI target core in roughly 600-800 LEs with on-chip DMA engines, leaving the bulk of the device for the application logic. Estimated: a 33 MHz PCI target core with DMA occupies approximately 1,200 LEs and 12 M4K blocks; full card functionality fits within 4,000 LEs.

Legacy Design Continuity

Many long-life industrial, military, and avionics programs continue to require the original Cyclone family for proven IP cores and bitstream-level compatibility with deployed systems. The EP1C6TC144-8 provides that continuity - a verified 144-TQFP drop-in with the same 5,980-LE architecture and same Quartus II toolchain support that customers have used for over a decade. For programs that must demonstrate RoHS compliance, the EP1C6T144C8N variant offers the same die with Pb-free lead finish. The 144-TQFP package remains the preferred choice when legacy PCB layouts and through-hole assembly processes must be preserved. Estimated: legacy IP re-use typically requires zero LEs of recompilation overhead - only bitstream regeneration through Quartus II.

What is the logic element count of EP1C6TC144-8?

The EP1C6TC144-8 contains 5,980 logic elements per the Cyclone Family Data Sheet. Each logic element is built from a four-input look-up table, a programmable flip-flop, and dedicated carry-chain logic, which is sufficient for typical glue-logic, state-machine, and small DSP pipelines but well below the density of Cyclone II/IV devices.

Is the EP1C6TC144-8 still in production in 2026?

The Intel/Altera Cyclone (original) family has been formally discontinued and placed under Not Recommended for New Designs (NRND). According to the verified web data, distributor inventory exists in the tens of thousands of units, but for new designs Intel recommends migrating to Cyclone II, Cyclone IV, or Cyclone V families.

What is the difference between EP1C6TC144-8 and EP1C6T144C8N?

Both parts share the same 144-TQFP package and the same Cyclone die with 5,980 LEs; the suffix difference reflects commercial vs extended-temperature screening and Pb-free options. The EP1C6TC144-8 uses the -8 speed grade, while the EP1C6T144C8N is the standard speed-grade 8 commercial Pb-free variant. They are drop-in compatible on the same footprint.

How much embedded memory does the EP1C6TC144-8 have?

The EP1C6TC144-8 includes 92,160 bits of embedded RAM organized as 20 M4K blocks, each providing 4,608 bits (4 Kbits plus parity). M4K blocks can be configured as single-port, dual-port, or FIFO memory, making them suitable for small line buffers, lookup tables, and shift registers in DSP pipelines.

Can the EP1C6TC144-8 interface with DDR SDRAM?

Yes, the EP1C6TC144-8 supports dedicated external memory interfaces for DDR SDRAM, QDR SRAM, and SDR SDRAM. The Cyclone architecture includes dedicated DQS (data strobe) delay circuitry and DLL-based clock alignment, which simplifies PCB routing and timing closure for DDR memories in this density range.

What is the difference between speed grades -6, -7, and -8 on the Cyclone family?

The Cyclone family uses lower numerical speed-grade designations to indicate faster parts. The -8 grade is the slowest (8 ns pin-to-pin), the -7 grade is approximately 15% faster, and the -6 grade is the fastest (approximately 25% faster than -8). For most glue-logic and control applications the -8 grade is adequate and is the most cost-effective option.

Where can I buy EP1C6TC144-8 today?

According to the verified web data fetched on 2026-09-06, EP1C6TC144-8 (and its lead-free sibling EP1C6T144C8N) stock exists at distributors including Arrow, LCSC, and Heisener, with unit pricing around $23-45 USD depending on quantity and screening. Lead times are typically immediate for in-stock parts but can extend when only franchised-stock inventory remains.

What is the price of EP1C6TC144-8 as of September 2026?

Pricing for EP1C6T144C8N (the standard Pb-free equivalent) is approximately $23.07 USD at 1,000-piece quantity, $30.20 USD at 100 pieces, and $44.81 USD at single-piece, as listed on LCSC and aggregated on Octopart on 2026-09-06. The original EP1C6TC144-8 may carry a price premium due to date-code and screening differences.

What is the lead time for EP1C6TC144-8?

EP1C6TC144-8 vs EP1C6Q240C8 - which is better for a new design?

Both parts use the same 5,980-LE Cyclone die and the same speed grade, differing only in package: the 144-TQFP (EP1C6TC144-8) exposes 92 user I/Os, while the 240-PQFP (EP1C6Q240C8) exposes 185 user I/Os. For new designs with sufficient board area, the 240-PQFP offers more I/O headroom; choose the 144-TQFP only when board space is constrained or when pin compatibility with an existing 144-TQFP layout is required.

What is the best drop-in replacement for EP1C6TC144-8?

The best drop-in replacements are same-family Cyclone parts in the same 144-TQFP package: EP1C6T144C8 (standard speed grade 8), EP1C6T144C8N (Pb-free standard grade 8), and EP1C6T144C7 (faster speed grade 7). All share the 144-TQFP pinout, the same 5,980-LE die, and identical configuration bitstream support, requiring only a Quartus recompile to switch.

Where can I download the EP1C6TC144-8 datasheet PDF?

The Cyclone Family Data Sheet is available from multiple sources including the Intel FPGA legacy documents page, the Altera archive at alterasemi.com (PDF link verified in the web data), datasheets.com, alldatasheet.com, and distributor product pages such as Octopart. The document covers DC characteristics, AC timing, configuration, JTAG, and ordering information.

Is EP1C6TC144-8 RoHS compliant?

RoHS compliance for the EP1C6TC144-8 depends on the date code and the part suffix. The 'N' suffix variants such as EP1C6T144C8N are explicitly Pb-free and RoHS compliant. The original EP1C6TC144-8 may have date codes that pre-date RoHS or that use lead-containing lead finish; confirm with the supplier's Certificate of Conformance for each lot before declaring compliance for end-product certification.

Can EP1C6T144C8N replace EP1C6TC144-8 directly?

Yes, the EP1C6T144C8N can directly replace the EP1C6TC144-8 on the same 144-TQFP footprint with no PCB changes. Both use the same Cyclone die, the same 5,980-LE logic capacity, the same 92,160-bit embedded memory, and the same configuration bitstream format. The 'N' suffix only indicates Pb-free lead finish and minor marking differences.

What are the most important specifications of EP1C6TC144-8 for power estimation?

The three most important specifications for power estimation are the 1.5 V VCCINT core supply, the 92,160-bit embedded RAM capacity, and the 92 user I/O pins in the 144-TQFP package. Together with the design's toggle rate and logic utilization, these drive the core dynamic current; use the Quartus II PowerPlay analyzer for accurate post-fit power estimation rather than static spreadsheet models.

Руководство по выбору

Choose EP1C6TC144-8 for new low-cost designs requiring 5,980 logic elements and up to 92 user I/Os in a through-hole-friendly TQFP package. Choose EP1C6T144C8N if RoHS/Pb-free compliance is required. Choose EP1C6T144C7 or EP1C6T144C7N for designs that need approximately 15% higher Fmax than the -8 grade. Choose EP1C6T144C6N for the fastest available commercial speed grade. Choose EP2C5T144C8N (Cyclone II) for new designs requiring longer-term continuity, since the original Cyclone family is NRND. Avoid using this part for new high-reliability automotive or aerospace programs - the family lacks AEC-Q100 qualification and is past its lifecycle window.

Заметки по проектированию

The EP1C6TC144-8 requires a clean 1.5 V core supply at up to approximately 500 mA for full logic utilization. Use a low-dropout regulator with at least 20% current headroom above the maximum expected core current, and place decoupling capacitors (0.1 uF plus 10 uF bulk) within 5 mm of each VCCINT pin. VCCIO banks should each have their own decoupling; mixing bank voltages requires careful isolation to prevent latchup.

The 144-pin TQFP package uses 0.5 mm pitch leads - trace escape routing requires vias in the land pattern or dog-bone fanout. Use a 4-layer PCB with continuous ground and power planes for signal integrity; route all clock and DQS signals first with controlled impedance. Place the EPCS configuration memory adjacent to the FPGA with the DATA and DCLK traces kept short and matched within 25 mm.

Do not apply 3.3 V signals to a 1.5 V VCCIO bank - this damages the I/O buffers. Confirm that all banks supplying 5 V-tolerant interfaces use the 3.3 V VCCIO setting. The original Cyclone family does not support hot-socketing; ensure power rails ramp monotonically and that nCONFIG is held low until all supplies are stable.

Estimated: at full 5,980-LE utilization with 100% toggle rate on all 92 I/Os at 100 MHz, the EP1C6TC144-8 dissipates approximately 1.0-1.5 W from the 1.5 V core. The 144-TQFP package thermal resistance is approximately 30 C/W junction-to-ambient with standard 4-layer PCB layout, so the junction temperature rise above ambient stays below 45 C in normal lab conditions. No external heatsink is required, but ensure airflow in enclosed industrial enclosures.
