EP1C6T144C8 개요

The Altera EP1C6T144C8 is a Cyclone family field-programmable gate array integrating 5,980 logic elements, 92,160 RAM bits, and 98 user I/Os in a 144-pin TQFP (commonly listed as 144-LQFP) package. It operates from a 1.5 V core supply and is built on a 0.13 μm all-layer copper SRAM process, targeting low-cost, high-volume applications with commercial temperature-grade ordering options.

A field-programmable gate array is an integrated circuit whose logic fabric can be configured after manufacturing. Unlike fixed-function ASICs, it contains programmable logic elements, embedded memory, and I/O blocks whose interconnects are set by SRAM configuration bits. In the device hierarchy, an FPGA is a programmable logic device within the broader category of integrated circuits; it offers hardware-like parallelism with software-like reconfigurability. Cyclone devices belong to Altera's low-cost FPGA family, positioned for applications that need dense parallel logic but do not require high-end transceivers or hardened processors.

The EP1C6T144C8 provides 5,980 logic elements, 92,160 bits of on-chip RAM, and 98 user I/O pins, making it suitable for glue logic, bus interfaces, and modest state machines. The 1.5 V core and 130 nm copper SRAM process deliver lower dynamic power than older 2.5 V FPGAs. The 144-pin TQFP package is a conventional surface-mount form factor with exposed leads that ease inspection and rework compared to fine-pitch BGA packages. The device supports JTAG boundary-scan testing and in-system configuration.

Internally, Cyclone FPGAs consist of logic array blocks containing multiple logic elements, embedded memory blocks, and clock management resources; however, exact M4K block and PLL counts for EP1C6 were not enumerated in the retrieved data and should be confirmed in the Cyclone FPGA Family Data Sheet. The architecture is SRAM-based, so configuration data is volatile and must be loaded from an external configuration device or host at every power-up. The I/O ring supports multiple single-ended interface standards, and the JTAG interface is used for both boundary-scan and configuration.

Typical applications include motor-control interface logic, display and sensor bridging, protocol conversion between UART/SPI/I2C and parallel buses, test equipment sequencing, and low-cost prototyping for students and hardware engineers. The large I/O count and 5,980 LEs are enough for state machines and data-path glue, while the TQFP package allows two-layer PCBs in many designs.

When designing with this device, verify the configuration scheme early. Because Cyclone FPGAs have no internal flash, they require an EPCS serial configuration device or a configuration host holding the SRAM bitstream; the selected scheme affects board area and BOM cost.

This data page synthesizes distributor availability, lead-free and speed-grade drop-in alternatives, package comparison data, and practical design guidance not stated in the bare datasheet extract, giving engineers a single-source decision reference for the legacy Cyclone family.

🏭

Industrial Motor Control

The EP1C6T144C8 fits industrial motor-control PCBs because its 98 user I/Os are sufficient for Hall-sensor inputs, quadrature encoder decoding, PWM signals, fault monitoring, and a host communication interface. With 5,980 logic elements, the FPGA can execute a state-machine-based current loop and external host handshaking without burdening a small microcontroller. The 1.5 V core and commercial temperature option keep cost low for indoor variable-frequency drives and servo controllers. Because the TQFP-144 package has leads, it is practical for modest multilayer boards that need cost-effective inspection. Place the FPGA beside an EPCS serial configuration device and isolate the noisy power stage; the FPGA can then concentrate on deterministic I/O timing rather than running software.

FPGA Prototyping and Education

For engineering education and early prototyping, the EP1C6T144C8 provides an approachable 144-pin TQFP platform with enough resources to teach combinational logic, state machines, memory access, and JTAG configuration. It contains 5,980 logic elements and 92,160 RAM bits, which are adequate for simple CPU cores, UARTs, and LED/switch interfaces. The package can be socketed or soldered on low-cost development boards, and the Cyclone family datasheet documents the JTAG configuration chain clearly. For a student board, use a USB-Blaster-compatible download cable and a small EPCS configuration device so the design can be loaded at power-up. The commercial C8 temperature range is acceptable for laboratory environments where the board is not exposed to extreme temperatures.

🧩

Sensor and Protocol Bridging

The EP1C6T144C8 is well suited for sensor and protocol bridging because its programmable logic can convert between parallel buses, SPI, I2C, UART, and arbitrary timing protocols without a dedicated protocol chip. With 5,980 LEs and 98 I/Os, the FPGA can monitor several digital sensors, assemble frames, buffer samples in on-chip RAM, and present them over a single serial link to a processor. The TQFP-144 package provides enough pins to attach multiple sensor headers and LEDs. Designers should pay attention to I/O voltage compatibility: the FPGA core is 1.5 V, so level translators are often needed when interfacing 3.3 V or 5 V sensors. The high configurability reduces board re-spins when the sensor protocol changes late in development.

Test and Measurement Instrument Control

Laboratory and production test equipment can use the EP1C6T144C8 to implement deterministic digital control for relays, switches, ADC strobes, DAC updates, and measurement sequences. The FPGA's 5,980 logic elements are enough for a flexible timing generator that produces non-real-time-independent pulse trains without CPU latency. Its 92,160 RAM bits can hold calibration coefficients or small waveform lookup tables, while 98 user I/Os connect to front-panel controls and data converters. Because many instruments run from a 1.5 V core with 3.3 V I/O, careful I/O-bank decoupling is critical when the FPGA drives long cables. The TQFP package and commercial temperature grade suit benchtop equipment in controlled indoor environments.

Display and Imaging Interface

The EP1C6T144C8 can serve as an interface bridge between image sensors or display timing signals and a host processor, thanks to its 5,980 logic elements and 98 I/Os. It can generate or decode pixel clocks, HSYNC, VSYNC, data-enable signals, and simple parallel data streams. The on-chip RAM provides small line buffers for synchronizing between asynchronous clock domains. The 144-pin TQFP package offers enough pins for camera modules, memory, and host connectors while remaining manufacturable on cost-sensitive boards. Memory-bandwidth limitations should be evaluated early because 92,160 bits is a line buffer rather than a large frame store; keep the FPGA role limited to timing conversion, cropping, or serial-to-parallel bridging rather than heavy image processing.

Communication Glue Logic and UART Expansion

EP1C6T144C8 enables deterministic communication glue logic such as UART expansion, SPI-to-parallel conversion, Manchester encoding, and simple bus arbitration. With 5,980 LEs, the FPGA can instantiate multiple soft UARTs or SPI controllers while leaving resources for status registers and watchdog timers. The 98 user I/O pins can split into multiple characteristically independent I/O banks, allowing the device to interface 1.8 V logic on one side and 3.3 V peripherals on another if the bank voltages are configured correctly. This part is particularly useful in legacy industrial equipment where an FPGA absorbs protocol translation that would otherwise require several ASSPs. Use controlled-impedance traces for high-speed clock outputs, but the TQFP package is forgiving for moderate-speed UART and SPI buses.

Where can I buy EP1C6T144C8 online?

EP1C6T144C8 is listed by distributors and aggregators such as DigiKey, Octopart, Fusion Worldwide, and FPGAkey. As of 2026-09-06, verified stock and checkout availability were not confirmed in the retrieved listings, so for this legacy Cyclone FPGA the normal purchasing path is a quote request to an independent distributor. The DigiKey product page identifies the functional parameters as 98 I/O, 92,160 RAM bits, and 5,980 logic elements in a 144-LQFP package.

What is the price of EP1C6T144C8?

No verified public unit price for EP1C6T144C8 was returned in the 2026-09-06 distributor data. Because this Altera Cyclone FPGA is an older-generation, largely obsolete product, most remaining inventory is sold on a quote basis and pricing varies with source, quantity, and condition. Engineers should request current quotes from distributors or brokers rather than relying on dated catalog prices.

What is the lead time for EP1C6T144C8?

Verified lead time for EP1C6T144C8 is not available from the retrieved data as of 2026-09-06. The part is from Altera's original Cyclone family built on 0.13-um technology, and most authorized distributors no longer carry fresh production stock. Buyers should treat this as an obsolete-sourcing item and ask the specific distributor for stock availability, condition, and delivery schedule before placing an order.

EP1C6T144C8 vs EP1C6T144C8N - which is better for new designs?

EP1C6T144C8N is the more assembly-friendly choice for new designs because the N suffix indicates the lead-free version of the same Cyclone FPGA. According to the Cyclone FPGA Family Data Sheet ordering scheme, both variants share the same 144-pin TQFP footprint, 5,980 logic elements, 92,160 RAM bits, and 98 user I/Os. The only primary difference is the package finish, so C8N is the closer drop-in for modern RoHS-sensitive manufacturing processes.

What is the difference between EP1C6T144C8 and EP1C6T144C7?

The difference is speed grade: EP1C6T144C8 is a speed grade 8 device while EP1C6T144C7 is one timing bin faster at grade 7. Both are Altera Cyclone FPGAs in the same 144-pin TQFP package with 5,980 LEs, 92,160 RAM bits, and 98 I/Os. Exact Fmax increase depends on the design, routing, and I/O standard, so a design should be re-timed with the -7 timing model if a performance upgrade is intended.

When should I choose EP1C6T144C8 over EP1C6T144I8?

Choose EP1C6T144C8 when your application operates only in a commercial temperature range and you do not need the industrial-temperature grade. EP1C6T144I8 is the industrial-temperature version of the same speed grade, still pin-compatible in the same 144-TQFP package. If the final product will be used outdoors, in an enclosure without climate control, or in an automotive-adjacent environment, selecting the I8 variant provides more operating margin.

Is EP1C6T144C8 suitable for motor-control applications?

Yes, EP1C6T144C8 is suitable for motor-control logic because its 98 user I/Os and 5,980 logic elements can implement PWM generation, encoder decoding, current-loop state machines, and host-interface logic. The 144-pin TQFP package is easier to route than a BGA on a two-layer motor-drive board. A configuration device such as an EPCS serial flash must be added because Cyclone devices are SRAM-based and have no internal nonvolatile configuration memory.

What is the best drop-in replacement for EP1C6T144C8?

The most direct drop-in replacement for EP1C6T144C8 is EP1C6T144C8N, which is the same Cyclone die in the same 144-pin TQFP package with the same speed grade and pinout, differing mainly in lead-free finish. For a faster timing bin, EP1C6T144C7 is also pin-compatible. For industrial-temperature operation, EP1C6T144I8 preserves the speed grade while extending the environmental rating. No verified cross-brand package-compatible FPGA equivalent was found in the retrieved web data.

Where can I download the EP1C6T144C8 datasheet PDF?

EP1C6T144C8 technical documentation is contained in the Cyclone FPGA Family Data Sheet, which is mirrored on sites such as alterasemi.com, alldatasheet.com, and datasheets.com. The retrieveable PDF at alterasemi.com covers feature definitions, architecture, configuration, JTAG boundary-scan testing, DC operating conditions, AC timing parameters, power references, and ordering information for Cyclone devices.

Is EP1C6T144C8 the same as EP1C6T144C7?

No, EP1C6T144C8 and EP1C6T144C7 are not identical: C8 indicates speed grade 8 and C7 indicates speed grade 7, with the lower number generally providing a faster device. Functionally they share the same Cyclone architecture, package, logic size, memory, and pinout, so they are board-compatible drop-in alternatives. A design intended for C8 can often be assembled with C7 after timing re-verification to gain additional clock margin.

What are the key specifications of EP1C6T144C8 that engineers should know?

EP1C6T144C8 is an Altera Cyclone FPGA with 5,980 logic elements, 92,160 RAM bits, and 98 user I/Os in a 144-pin TQFP package. It uses a 1.5 V core supply and is fabricated with a 0.13-um, all-layer copper SRAM process. The device is volatile and must be configured at power-up. It supports JTAG boundary-scan and is available with a C8 speed-grade commercial ordering suffix.

What is the best non-Altera equivalent for EP1C6T144C8?

No verified non-Altera drop-in equivalent for EP1C6T144C8 was found in the cross-reference data retrieved on 2026-09-06. Although several FPGA competitors make devices with similar logic density, none was confirmed as pin-compatible with the Altera 144-pin TQFP footprint. Engineers needing a replacement from another brand should compare pin tables and perform a PCB redesign rather than assume a mechanical or electrical cross-reference.

What FPGA architecture is used in EP1C6T144C8?

EP1C6T144C8 uses Altera's Cyclone FPGA architecture, an SRAM-based programmable fabric built with a 1.5 V, 0.13-um, all-layer copper process. The family datasheet divides the architecture into logic array blocks, embedded memory, I/O elements, clock networks, and JTAG circuitry. Exact numbers for PLLs and dedicated memory blocks in this specific density were not enumerated in the retrieved text and should be confirmed from the Cyclone family data sheet.

What configuration methods does EP1C6T144C8 support?

EP1C6T144C8 supports SRAM-based configuration, meaning its bitstream must be loaded at every power-up. Cyclone devices typically support JTAG configuration and serial configuration from external Altera configuration devices or a host processor. Because the retrieved data does not include the detailed configuration chapter, confirm the exact active/passive serial modes and pin connections in the Cyclone FPGA Family Data Sheet before finalizing the PCB.

선택 가이드

Choose EP1C6T144C8 when you need an Altera Cyclone FPGA with 5,980 LEs, 92,160 RAM bits, and 98 user I/Os in a commercial temperature-grade, 144-lead TQFP that is easy to prototype and rework. If the manufacturing line requires lead-free components, select EP1C6T144C8N as the direct drop-in. If timing closure demands additional margin, use EP1C6T144C7; if the equipment will be exposed to a wider temperature environment, choose EP1C6T144I8. For exact drop-in needs, all of these share the same TQFP-144 pinout and board footprint. Because no verified cross-brand pin-compatible FPGA equivalent was identified, moving to another vendor will require a pin map review and a new PCB layout.

설계 노트

EP1C6T144C8 requires a 1.5 V core supply, but exact current consumption depends on logic utilization, clock frequency, and I/O load. Estimated: a small design using 50% of 5,980 LEs at 100 MHz may draw a few hundred milliamps from the 1.5 V rail, so use a low-dropout regulator or buck converter sized with margin; place 100 nF ceramic decoupling caps near each VCC pin and add a bulk 10 uF capacitor per power pin group. The exact recommended power-up sequence and ramp rates should be taken from the Cyclone FPGA Family Data Sheet.

Because this is a 144-pin TQFP with a nominal 0.5 mm or 0.65 mm lead pitch, use stencil-printed solder paste and avoid hand-soldering large production volumes. Provide a solid ground plane under the FPGA and keep bypass capacitors within a few millimeters of their corresponding VCC pins. The package has no exposed center pad on standard TQFP construction, so thermal relief occurs through leads and planes; ensure the PCB has copper pours beneath the part to help spread heat even though the primary cooling path is through convection.

Do not assume EP1C6T144C8 contains nonvolatile configuration memory. It is SRAM-based and will lose its bitstream at power-off; the design must include an EPCS device, configuration host, or download cable. Also verify I/O bank voltages before connecting peripheral devices, because the FPGA core is 1.5 V but I/O supplies are typically 1.8 V, 2.5 V, or 3.3 V depending on the I/O bank configuration. Connecting a 5 V logic signal directly to a 3.3 V bank without a series resistor can damage the input structure.
