EP1C6TC144 概要
A Field-Programmable Gate Array (FPGA) is a programmable logic device (PLD) that allows designers to implement custom digital logic, memory blocks, and I/O protocols by configuring an array of configurable logic blocks (CLBs), embedded RAM, and routing resources after PCB assembly. FPGAs sit hierarchically under programmable logic -> logic IC -> integrated circuit -> semiconductor. Unlike an ASIC, an FPGA is reprogrammable in-system, making it ideal for prototyping, low-volume production, and designs requiring frequent logic updates.
Key features of the EP1C6TC144 include up to 92,160 bits of embedded SRAM distributed in M4K blocks, dedicated 18x18 multipliers for DSP, four phase-locked loops (PLLs) for clock management, and support for LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards. Configuration can be loaded through passive serial (PS), active serial (AS), or JTAG modes. The device is built on a 0.13 µm SRAM process and operates from a 1.5 V core supply.
Architecturally, the Cyclone device uses a 2D row-and-column interconnect with embedded array blocks (EABs) repurposed as M4K memory blocks, a four-input look-up table (LUT)-based logic element, and dedicated multiplier blocks. The 144-pin TQFP package has 1.0 mm pitch and supports up to 98 user I/O with 3.3 V/2.5 V-tolerant banks. The silicon is identical to the EP1C6T144 variants - only the operating temperature and speed grade differ.
Typical applications include industrial control and motor-drive glue logic, low-cost video processing, consumer-electronics glue logic, communications protocol bridging, and educational/hobbyist digital-design platforms. The EP1C6TC144 is also widely used as a low-density prototyping target for designs that may later migrate to Cyclone II/III/IV or MAX-series devices.
Designers should budget roughly 80 mW of static core power plus dynamic power proportional to toggle rate, and follow Altera's recommended decoupling scheme (one 100 µF + multiple 0.1 µF + 1 nF per supply pin). Configuration data must be loaded from an EPCS serial configuration device or a microcontroller on every power-up because the SRAM configuration is volatile.

主な用途
EP1C6TC144 の用途: 6 件s: Industrial Control and Motor Drive Glue Logic, Low-Cost Video Processing and Image Pipeline, Consumer Electronics Glue Logic and Custom Controllers, Communications Protocol Bridging, Educational and Hobbyist Digital Design Platforms, ASIC Prototype and Logic-Replacement Designs.
Industrial Control and Motor Drive Glue Logic
The EP1C6TC144 fits industrial control and motor-drive applications because its 5,980 logic elements and 92 kbit embedded RAM provide ample capacity for glue-logic, encoder interfaces, and PWM generation without external MSI glue. The 144-pin TQFP package gives 98 user I/O - enough for typical multi-axis drives combining PWM, Hall-effect feedback, and a parallel host interface. Cyclone I industrial variants operate 0 C to +85 C (commercial) or -40 C to +100 C (industrial), making them viable for cabinet-mounted controls. The 1.5 V core plus 3.3 V I/O banks allow direct interfacing to legacy industrial 5 V logic through current-limiting resistors.
おすすめ
Low-Cost Video Processing and Image Pipeline
The EP1C6TC144 is well suited to low-cost video processing pipelines that require hardware-accelerated FIR filtering, deinterlacing, or color-space conversion. The 5,980 logic elements can implement a moderate-width image-processing datapath operating at video pixel rates, and the embedded M4K blocks can hold line buffers. The 144-pin TQFP supports enough I/O for 18-24-bit parallel video buses plus a control interface. Designers use the dedicated multipliers for video scaling and DCT blocks. For 1080p-class throughput, however, Cyclone II/III/IV devices with more logic and higher-speed LVDS I/O are typically required.
おすすめ
Consumer Electronics Glue Logic and Custom Controllers
Consumer-electronics designers use the EP1C6TC144 as cost-effective glue logic to replace several discrete MSI parts and microcontrol peripherals. The 5,980 logic elements fit custom protocol bridges, display timing controllers, and audio-stream multiplexers in a single 144-pin TQFP. The 1.5 V core plus 2.5 V/3.3 V I/O banks can interface directly to DDR memory, LCD panels, and audio codecs. The Cyclone I's commercial temperature range (0 C to +85 C) covers most indoor consumer environments, and the AS configuration mode allows standalone boot from a low-cost EPCS1 device - critical for cost-sensitive consumer designs.
おすすめ
Communications Protocol Bridging
The EP1C6TC144 bridges legacy and modern communications protocols by implementing serializer/deserializer (SERDES) functions in logic, UART/USB bridges, and simple MAC-layer state machines. With 5,980 logic elements and 98 user I/O, the device fits UART/SPI/I2C-to-parallel conversion, custom protocol framing, and timing-sensitive bit manipulation. The two PLLs provide clock generation for multiple baud rates or sample clocks from a single crystal. The TQFP-144 package supports the multiple voltage-domain banks required for level translation between 5 V legacy and 3.3 V/2.5 V modern interfaces.
おすすめ
Educational and Hobbyist Digital Design Platforms
The EP1C6TC144 has been a popular FPGA on educational and hobbyist boards because it offers 5,980 logic elements - enough for full CPU cores (e.g. Nios II, RISC-V soft cores) and modest peripherals - in a breadboard-friendly TQFP-144 footprint. The 92 kbit embedded RAM is sufficient for instruction caches and small data buffers. Low-cost JTAG programming via USB-Blaster and free Quartus II Web Edition software make it ideal for university labs. The commercial temperature range (0 C to +85 C) covers all classroom and hobbyist environments. Today, however, most new educational designs target the Cyclone IV EP4CE6 or Cyclone 10 LP 10CL006 because of active tooling support.
おすすめ
ASIC Prototype and Logic-Replacement Designs
The EP1C6TC144 is widely used as an ASIC prototyping target and for replacing EOL ASICs that are no longer available. Its 5,980 logic elements and 92 kbit embedded RAM are sufficient to emulate small-to-medium ASICs in the same 144-pin TQFP footprint as the original part. The SRAM-based configuration means engineers can iterate designs in minutes via JTAG without re-spinning masks. Two PLLs provide clock synthesis, and the LVCMOS/LVTTL I/O banks support the mixed-voltage interfaces common in legacy ASIC designs. For functional verification before ASIC tape-out, the same Quartus project can be retargeted to a larger Cyclone II/III/IV device on a separate board.

設計ノート
The EP1C6TC144 requires a tightly regulated 1.5 V core supply (VCCINT) with at least ±5 % tolerance and a separate 3.3 V or 2.5 V VCCIO supply per bank. According to the Cyclone Family Handbook Section I, decouple each VCCINT pin with one 0.1 µF ceramic and one 10 µF bulk capacitor placed within 5 mm of the package. Estimate: total core current is roughly 100 mA idle plus dynamic current of 5-15 mA per MHz of toggling logic, so a 500 mA LDO is appropriate for most designs.
Configuration is volatile - the SRAM bitstream must be reloaded on every power-up. The EP1C6TC144 supports PS (passive serial), AS (active serial from EPCS device), and JTAG configuration modes. According to the Cyclone Family Handbook, MSEL[1:0] pins select the mode and must be pulled up/down with 10 kΩ resistors. For production boards, use AS mode with an EPCS1 (1 Mbit) for designs under 1 Mbit of bitstream, or EPCS4/EPCS16 for larger designs.
The TQFP-144 package has 0.5 mm lead pitch (corrected from 1.0 mm) requiring fine-pitch PCB layout. According to Altera's Cyclone I layout guidelines, use 0.2 mm trace/space rules, micro-via fanouts for inner-row escape, and a continuous ground plane under the package for thermal dissipation. Estimated: thermal resistance θJA of the TQFP-144 is approximately 28 C/W on a 4-layer PCB with no airflow; at typical 1.5 V × 100 mA core plus I/O loading, junction temperature rise is ~5 C above ambient, well within commercial ratings.
Common pitfalls when designing with the EP1C6TC144 include (1) forgetting that nCONFIG must be held low during power-up to trigger reconfiguration, (2) leaving JTAG pins floating when not using JTAG - tie TDI/TMS to VCCIO via 10 kΩ pull-ups, and (3) mixing 3.3 V and 2.5 V I/O standards on the same bank - VCCIO is bank-wide and cannot be split. According to the Cyclone device errata sheet, the nCE pin must be tied low for single-FPGA configurations.
