EP1C6T144C8 概要
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.

主な用途
EP1C6T144C8 の用途: 6 件s: Industrial Motor Control, FPGA Prototyping and Education, Sensor and Protocol Bridging, Test and Measurement Instrument Control, Display and Imaging Interface, Communication Glue Logic and UART Expansion.
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.

設計ノート
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.
