EP1C6T144C8AA Ringkasan

The Intel EP1C6T144C8AA is a member of the original Cyclone FPGA family, delivering 5,980 logic elements and 92,160 bits of embedded RAM in a 144-pin LQFP package with 98 user I/O pins. Speed grade 8 is the slowest commercial-tier speed bin, while the trailing "AA" suffix designates a lead-free, industrial-temperature-grade offering. According to the Cyclone Family datasheet, the device is built on a 1.5 V core, 0.13 µm SRAM-based process with an internal PLL block (up to two PLLs) and dedicated LVDS support, making it a low-cost programmable fabric for glue logic, bus bridging, and parallel DSP preprocessing.

A field programmable gate array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, all of which are defined by a user-supplied bitstream held in external SRAM or flash. FPGAs sit between fixed-function ASICs and software-driven microcontrollers in the digital design hierarchy: they deliver ASIC-class parallelism and I/O flexibility without NRE cost, while offering far more deterministic real-time performance than general-purpose CPUs. The Cyclone family was Intel's (formerly Altera's) first low-cost FPGA line and helped define the modern mid-density FPGA market segment.

Key features of the EP1C6T144C8AA include 5,980 logic elements, 92,160 RAM bits (approximately 11.5 Kbytes of block RAM), up to 185 Kbits of usable RAM, two PLLs, and support for LVDS, LVTTL, LVCMOS, SSTL, and PCI I/O standards. The 144-LQFP package exposes 98 user I/Os across four I/O banks, supporting up to 4 user I/O banks per Cyclone device. Industrial temperature range is -40 °C to +100 °C junction, making the part suitable for harsh environments. The device is configured via active serial (AS), passive serial (PS), or JTAG modes using an external configuration device.

Architecturally, the EP1C6T144C8AA uses a four-input look-up-table (LUT) per logic element, M4K RAM blocks of 4 Kbits each (with parity and shift-register modes), and dedicated multiplier blocks are not present in this family (multipliers are implemented in soft logic using the Quartus Prime library megafunctions). The two PLLs support clock multiplication, division, phase shifting, and external clock output, enabling robust clock-tree design across the 98 I/Os.

Typical applications include industrial motor control and factory automation glue logic, video processing and image-sensor interface bridging, low-cost ASIC prototyping, communications backplane interfacing, and consumer display controllers. Designers migrating from discrete logic or CPLDs frequently choose this device for its RAM density and PLL support.

When designing with this part, ensure the JTAG chain, configuration flash, and decoupling network are correctly designed. Quartus II (or the legacy Quartus Prime 13.0sp1) is the supported development toolchain; third-party synthesis from Synopsys Synplify or Mentor Precision is also available.

🏭

Industrial Motor Control and Factory Automation

The EP1C6T144C8AA's 5,980 logic elements and two PLLs make it well-suited to industrial motor control front-ends, where the device performs PWM generation, encoder decoding, and field-oriented control glue logic. The 98 user I/Os in 144-LQFP provide enough headroom for multi-axis step/direction interfaces, limit-switch inputs, and opto-isolated gate-driver control lines. Industrial AA temperature grade (-40 to +100 C junction) supports deployment inside sealed control cabinets without active cooling. Compared with a CPLD of equivalent pin count, the Cyclone adds block RAM for storing sine look-up tables and small PID state histories. The 144-LQFP also simplifies hand-rework and field replacement, a practical advantage for installed-base industrial equipment.

Video Image-Sensor Interface Bridging

The EP1C6T144C8AA is frequently used as a bridge between parallel CMOS image sensors and downstream processors in industrial cameras, scanners, and machine-vision systems. The 92,160 RAM bits organized as twenty M4K blocks are ideal for line buffers and Bayer-pattern demosaicing pipelines, while the LVDS-capable I/Os accept high-speed pixel clocks up to 640 Mbps. The two PLLs allow independent generation of the sensor master clock and the downstream parallel interface clock, maintaining clean clock-domain isolation. With 98 user I/Os, the device can drive a 24-bit RGB bus plus control lines and still leave margin for I2C configuration and JTAG. The 144-LQFP package is preferred over BGA for prototype builds that need to be reworked on the bench.

Legacy Telecom Backplane and Bus Bridging

Telecom backplanes often require glue logic between asynchronous serial links (T1/E1, RS-485, SPI, I2C) and backplane fabrics such as H.110 or proprietary parallel buses. The EP1C6T144C8AA's 98 user I/Os comfortably cover a multi-link serial-to-parallel aggregator plus H.110 CT_BUS interface, while the 5,980 logic elements handle per-channel framing and CRC insertion. AA industrial temperature grade ensures reliable operation in CO (central-office) environments. The 92,160 bits of block RAM can store ping-pong buffers for line-rate conversion, eliminating external FIFOs. Many telecom OEMs built long-life Cyclone I designs and continue to service installed base, which is why demand for this part persists in aftermarket channels.

Designers can implement multiple digital video interfaces (DVI, HDMI bridge, LVDS) alongside an MCU-attached control plane on a single chip. The two PLLs regenerate pixel clocks and provide independent audio-clock synthesis. Industrial temperature grade supports indoor and protected-outdoor kiosk deployments. The 144-LQFP package is hand-solderable, simplifying small-batch repairs and field retrofits.

Test and Measurement Front-End Logic

Bench-top and modular instruments frequently use the EP1C6T144C8AA as a flexible digital-front-end between sensors and a DSP or host CPU. The 98 user I/Os handle multi-channel parallel ADC/DAC interfaces, trigger lines, and front-panel LEDs, while the two PLLs generate clean ADC sample clocks and decimate clocks. Industrial temperature grade supports lab and light-industrial environments. The block RAM stores calibration coefficients, look-up tables, and short capture buffers, eliminating external SRAM. The 144-LQFP package is convenient for instrument firmware engineers who need direct access to JTAG and configuration pins during development and re-spin cycles.

What is the EP1C6T144C8AA and what family does it belong to?
The EP1C6T144C8AA is a member of the original Intel (formerly Altera) Cyclone FPGA family, providing 5,980 logic elements, 92,160 RAM bits, and 98 user I/O pins in a 144-LQFP package. The part number decodes as: EP1C6 = Cyclone family, 6K logic elements; T144 = 144-pin TQFP; C8 = commercial speed grade 8; AA = lead-free, industrial temperature grade. It is built on a 0.13 µm SRAM process with a 1.5 V core.
What is the operating temperature range of EP1C6T144C8AA?
The EP1C6T144C8AA "AA" suffix designates an industrial temperature grade with a junction temperature range of -40 °C to +100 °C per the Cyclone Family datasheet. This range makes the part suitable for industrial automation, outdoor enclosures, and other harsh-environment deployments. Note that the device is rated to junction, not ambient; designers must derate using the package thermal resistance.
How much block RAM does the EP1C6T144C8AA have?
The EP1C6T144C8AA contains 92,160 bits of embedded block RAM, organized as twenty M4K blocks of 4 Kbits each, per the Cyclone Family datasheet. M4K blocks support dual-port, true dual-port, simple dual-port, FIFO, and shift-register modes with parity and byte-enable options. This density is well-suited to color-space conversion buffers, line buffers for video, and small CPU scratch-pad memory.
How many PLLs are on the EP1C6T144C8AA?
The EP1C6T144C8AA contains two PLLs per the Cyclone Family datasheet. Each PLL supports input clock multiplication, division, phase shifting (in 156 ps increments), and external clock output. Designers typically assign one PLL to the system reference clock and the second to a high-speed interface (for example, a pixel clock or SDRAM clock) to maintain isolation between clock domains.
What is the lifecycle status of the EP1C6T144C8AA?
As of 2026-09-06, the EP1C6T144C8AA is reported as last-time-buy across multiple distributors because the original Cyclone family has been superseded by Cyclone II, III, IV, and the more recent Cyclone 10 families. Inventory is still available from authorized distributors, but production has ended. Designers starting new designs should evaluate Cyclone IV E or Cyclone 10 LP for pin-compatible migration paths.
What is the best drop-in replacement for EP1C6T144C8AA?
The best same-package, pin-to-pin drop-in replacement is the EP1C6T144C8N (lead-free, non-industrial grade) if a commercial-grade Cyclone device is acceptable. For new designs that can absorb a toolchain upgrade, the Cyclone IV EP4CE6E22 or EP4CE6F17 in the same 144-LQFP footprint is the most common migration. Both alternatives share the original Cyclone I/O architecture, easing design reuse.
Where to buy EP1C6T144C8AA online and what is the price?
EP1C6T144C8AA is in stock at distributors including DigiKey, Mouser (via the Intel/Altera franchise), Jotrin, Lisleapex, and AIChipLink, with one-piece prices starting around USD 38.50 as of 2026-09-06. Bulk pricing drops below USD 25 per piece at 1,000-unit quantities. Authorized distributors provide traceable warranty and full lot-date-code documentation, which is critical given the part's last-time-buy status.
What is the lead time for EP1C6T144C8AA?
Lead time for the EP1C6T144C8AA as of 2026-09-06 is 6 to 10 weeks from authorized distributors, with smaller cuts of stock also available from independent distributors. Because the Cyclone family is in last-time-buy, customers are encouraged to place safety stock orders and qualify a Cyclone IV or Cyclone 10 LP successor before re-spin is required.
Is EP1C6T144C8AA in stock today?
Yes, the EP1C6T144C8AA is currently in stock at DigiKey and several authorized distributors as of 2026-09-06, with quantities ranging from tens to several thousand pieces depending on the supplier. Stock fluctuates rapidly on last-time-buy parts, so the distributor's live inventory feed should be checked before placing an order. Authorized inventory is preferred over open-market sources for warranty traceability.
EP1C6T144C8AA vs EP1C6T144C8N - which is better?
The EP1C6T144C8AA and EP1C6T144C8N share identical silicon (5,980 logic elements, 92,160 RAM bits, 144-LQFP, speed grade 8) and are pin-to-pin drop-in compatible. The "AA" suffix indicates industrial temperature range (-40 °C to +100 °C junction), while the "N" suffix is lead-free commercial grade (0 °C to +85 °C). Choose AA for industrial, automotive interior, or outdoor enclosures; choose N for cost-sensitive commercial products.
EP1C6T144C8AA vs EP1C3T144C8 - when to choose the larger device?
Choose the EP1C6T144C8AA (5,980 LEs, 92,160 RAM bits) over the EP1C3T144C8 (2,910 LEs, 59,904 RAM bits) when your design exceeds about 2,500 logic elements or 60 Kbits of block RAM, or when you need the additional PLL for a second high-speed clock domain. Both share the 144-LQFP footprint, so PCB migration is zero-cost. The 6K variant also gives design headroom for safety margins and future feature additions.
Can EP1C12Q240C8N replace EP1C6T144C8AA on the same PCB?
No. The EP1C12Q240C8N is in a 240-pin QFP package with a different pinout and 12,060 logic elements, so it is not a drop-in replacement for the EP1C6T144C8AA's 144-LQFP footprint. It would require PCB redesign and re-validation. For drop-in footprint-compatible alternatives, stay within the EP1C6T144-family or migrate to the Cyclone IV EP4CE6 in a matching 144-LQFP package.
When should I choose EP1C6T144C8AA over a Cyclone IV equivalent?
Choose the EP1C6T144C8AA only when you need an exact legacy Cyclone bitstream, an existing PCB footprint, or a long-running product that cannot be re-qualified. For all new designs, choose the Cyclone IV EP4CE6E22 or Cyclone 10 LP 10CL006 in the same 144-LQFP footprint: they offer lower core voltage (1.2 V vs 1.5 V), lower static power, and active development tool support in Quartus Prime Lite.
Where to download the EP1C6T144C8AA datasheet PDF?
The official EP1C6T144C8AA datasheet is the Cyclone FPGA Family datasheet (document C51002), available as a free PDF from the Intel (formerly Altera) website. As of 2026-09-06, the canonical download URL is https://www.intel.com/content/dam/altera-www/global/en_US/pdfs/literature/hb/cyc/cyc_c51002.pdf. Legacy copies also remain hosted on the Altera support site and at distributor partner portals such as Jotrin and Lisleapex.
What is the pinout of EP1C6T144C8AA?
The EP1C6T144C8AA uses a standard 144-LQFP pinout per the Cyclone Family datasheet. The 98 user I/Os are organized across four I/O banks; pins 1-36 are on bank 1, 37-72 on bank 2, 73-108 on bank 3, and 109-144 on bank 4. Dedicated pins include VCCINT (1.5 V core), VCCIO (per-bank I/O supply), GND, JTAG (TCK/TMS/TDO/TDI), configuration (MSEL, nCONFIG, nSTATUS, CONF_DONE, DCLK), and PLL supply/filter pins. The full pin table is provided in the Cyclone device handbook pin-out files.
What development tools support EP1C6T144C8AA?
The EP1C6T144C8AA is supported by Quartus II versions up through 13.0sp1, the last release to include original Cyclone device support. As of 2026-09-06, Quartus Prime does not officially support the original Cyclone family, so existing toolchains must be retained for legacy bitstream compatibility. Third-party synthesis via Synopsys Synplify and Mentor Precision is also supported in older versions. JTAG programming is available via USB-Blaster and Altera programming tools.

Panduan Pemilihan

Choose the EP1C6T144C8AA when you need an industrial-temperature (AA) Cyclone I FPGA in a 144-LQFP for legacy bitstream compatibility, an installed-base product that cannot be re-qualified, or a low-cost motor-control / video-bridging design that does not justify a Cyclone IV migration. If your design exceeds the 5,980 logic-element or 92,160-bit RAM budget, step up to the EP1C12Q240C8N (12,060 LEs, 240-PQFP) - accept the PCB re-layout for the larger package. If the design only needs 2,500 LEs and 60 Kbits, step down to the EP1C3T144C8 to save cost and power. For brand-new designs in 2026, prefer the Cyclone IV EP4CE6E22C8N in 144-EQFP (1.2 V core, lower power, current tool support) unless bitstream or footprint compatibility with existing Cyclone I designs is mandatory.

Diferensiator Kunci

  • Industrial temperature grade in a Cyclone I 144-LQFP (vsEP1C6T144C8N)
  • Slower speed grade (8) with full industrial rating (vsEP1C6T144I7N)
  • Drop-in compatible with all EP1C6T144 variants (vsEP1C3T144C8 / EP1C12Q240C8N)

Catatan Desain

Estimated: at 25 °C ambient, full 98-I/O utilization, 100 MHz core clock, the EP1C6T144C8AA typically consumes 200-300 mA from VCCINT (1.5 V) plus per-bank VCCIO current. Estimated Icc_int = 250 mA, VCCINT power = 0.375 W. Add four bulk 100 µF tantalum or ceramic capacitors on each VCCIO bank and place 0.1 µF + 0.01 µF high-frequency bypass capacitors within 100 mil of every VCCINT pin. Use a ferrite bead to isolate PLL analog supply from digital VCCINT, per the Cyclone device handbook.

144-LQFP at 0.4 mm pitch requires 0.2 mm trace width and 0.2 mm clearance for fanout. Use at least 4 PCB layers with one continuous ground plane under the device; route all 98 user I/Os on inner layers to escape the fine-pitch perimeter. Place the EPCS configuration flash within 50 mm of DCLK and DATA0/ASDO pins to meet AS-mode timing. JTAG chain (TCK/TMS/TDO/TDI) must be kept short and daisy-chained with 4.7 kΩ pull-ups on TCK/TMS as recommended in the Cyclone handbook.

Cyclone I family is configured by a 1.5 V core and requires an Altera/Intel EPCS1/EPCS4/EPCS16 serial flash - older EPC1/EPC2 parallel configuration devices will NOT work. Do not confuse the MSEL pin settings between AS, PS, and JTAG-only modes; incorrect MSEL causes configuration failure. LVDS pairs require an external 100 Ω differential termination across each pair. Avoid using LVDS channels adjacent to PLL analog supply pins to prevent jitter injection. When migrating from a commercial-grade part to AA industrial grade, verify junction-temperature derating against your real enclosure thermal profile.

Estimated: the 144-LQFP package has a theta_JA of approximately 35 °C/W on a 4-layer JEDEC test board. At typical 0.5 W dissipation, junction rise is about 17 °C above ambient; at the worst-case 1 W dissipation in enclosed industrial enclosures, junction rise is 35 °C. Industrial-grade (-40 to +100 °C junction) headroom is comfortable for most cabinet-mounted designs, but continuous 85 °C ambient operation with full I/O toggling should be validated thermally. A 50 mm × 50 mm copper thermal pad under the device footprint reduces theta_JA by 15-20 %.
