EP1C6T144I8 概要
What is a Cyclone FPGA? A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and dedicated hard IP such as block RAM, PLLs, and I/O serializers. Unlike fixed-function ASICs, FPGAs are programmed by the end user after manufacture, making them ideal for prototyping, low-volume production, and designs that must evolve in the field. The Cyclone family sits in the low-cost, low-power tier of the Intel FPGA portfolio - positioned below Cyclone II/III/IV/V and well below Stratix and Arria families. Within this hierarchy: Cyclone -> low-cost FPGA -> programmable logic -> semiconductor IC. The EP1C6 variant occupies the mid-density position in the original Cyclone lineup, between EP1C3 (smaller) and EP1C12/EP1C20 (larger).
Key features of the EP1C6T144I8 include 5,980 logic elements, 92,160 bits of embedded RAM (M4K blocks), 98 maximum user I/O pins, two analog PLLs with four outputs each, and support for LVTTL, LVCMOS, SSTL, and differential I/O standards. The 144-TQFP package offers a 1.0mm lead pitch and gull-wing leads compatible with standard SMT assembly and hand-rework, eliminating the need for fine-pitch BGA handling.
Technically, the EP1C6T144I8 is built on a 1.5V core with multi-voltage I/O banks supporting 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V interfacing. The device uses SRAM-based configuration memory, requiring a configuration flash or controller on every board. Configuration is via passive serial (PS), active serial (AS), or JTAG. The I8 suffix denotes the industrial temperature grade (-40C to +100C ambient, junction to +135C).
Typical applications include industrial motor control, video processing pipelines, custom peripheral expansion, glue logic replacement, software-defined radio front-ends, and educational/development platforms. The Cyclone I/O flexibility makes it well-suited for bridging legacy 5V buses to modern 3.3V processors.
When designing with this part, ensure the configuration scheme is selected (AS/PS/JTAG) and that a valid configuration clock source is present at power-up. Unused pins should be left floating per datasheet guidance; the TQFP-144 footprint simplifies prototype bring-up versus BGA alternatives.

主な用途
EP1C6T144I8 の用途: 6 件s: Industrial Motor Control and Drive Interfaces, Video Processing and Image Pipeline Front-Ends, Custom Peripheral Expansion and Glue Logic Replacement, Software-Defined Radio (SDR) Front-End Interfaces, Legacy Communication Protocol Bridges (RS-232/422/485, CAN, SPI, I2C), Educational Development Boards and FPGA Training Platforms.
Industrial Motor Control and Drive Interfaces
The EP1C6T144I8 is widely deployed in industrial motor-control boards where its 5,980 logic elements and 98 user I/O provide ample capacity for PWM generation, encoder feedback decoding, and CAN/RS-485 protocol bridging. The industrial temperature grade (-40C to +100C ambient) ensures reliable operation in factory-floor cabinets and outdoor enclosures where ambient temperatures swing widely. Designers use the two on-chip PLLs to derive precise PWM frequencies and to clock the encoder interface, while the 20 M4K RAM blocks hold commutation lookup tables. The TQFP-144 package is hand-reworkable in the field - a critical advantage when production boards must be serviced on-site. Cyclone I is mature and well-supported by legacy Quartus II design flows, making it ideal for long-lifecycle industrial products.
おすすめ
Video Processing and Image Pipeline Front-Ends
The EP1C6T144I8 handles ITU-R BT.656 and VGA-rate video pipelines up to 275 MHz internal logic, with the 92,160 bits of M4K RAM used as line buffers and chroma interpolators. Its 98 user I/O accept parallel video buses (8/16/24-bit) plus sync and clock signals, while the LVDS support enables direct connection to camera-link serializers. Designers implement de-interlacing, color-space conversion, and on-screen-display overlays entirely in fabric. The 144-TQFP package provides enough I/O for mid-resolution pipelines (up to 720p) while keeping the board single-sided for cost-sensitive consumer products. For designs that need HD-rate processing, the migration target is Cyclone IV E with 360 kbits of RAM.
おすすめ
Custom Peripheral Expansion and Glue Logic Replacement
The EP1C6T144I8 replaces multiple PALs, FPGAs, and discrete MSI logic in legacy industrial backplanes. The 5,980 logic elements can implement parallel-to-serial converters, custom bus arbiters, watchdogs, and timing generators that previously required dozens of 74-series TTL packages. The device's support for 5V-tolerant LVTTL and 3.3V LVCMOS in separate I/O banks lets a single FPGA bridge a 5V VME bus to a 3.3V processor without external level shifters. Active-serial configuration via an EPCS1 flash (typically 1 Mbit) holds the bitstream, allowing in-field firmware updates through JTAG. The TQFP-144 footprint simplifies through-hole rework on legacy boards that were not designed for BGA assembly.
おすすめ
Software-Defined Radio (SDR) Front-End Interfaces
The EP1C6T144I8 serves as the digital interface between an analog front-end (AFE) and a host DSP or processor in cost-sensitive software-defined radio designs. Its LVDS inputs accept high-speed ADC samples, while the on-chip PLLs generate the ADC sampling clock and the host interface clock from a single reference. The 20 M4K blocks (each 4 kbit) provide channelisation buffers and FIFO interfaces between the ADC and the host. With 5,980 LEs the device can implement channel filters, DDC stages, and protocol framing logic for narrow-band radios. The industrial temperature grade makes it suitable for outdoor and vehicular SDR installations. Power consumption is approximately 200-400 mW depending on toggle rate and clock speed.
おすすめ
Legacy Communication Protocol Bridges (RS-232/422/485, CAN, SPI, I2C)
The EP1C6T144I8 is often used as a multi-protocol bridge chip in industrial gateways, translating between RS-232, RS-422/485, CAN, SPI, and I2C buses. The 98 user I/O support multiple transceivers simultaneously, while the 5,980 LEs implement UART cores, SPI masters, and CAN controllers in soft IP. Industrial temperature grade ensures operation in substation, factory, and outdoor installations. Designers configure the device through JTAG during development and lock the bitstream into an EPCS flash for production. The TQFP-144 package is well-suited for through-hole-style repair in legacy equipment cabinets.
おすすめ
Educational Development Boards and FPGA Training Platforms
The EP1C6T144I8 is a staple on university and hobbyist FPGA development boards because its TQFP-144 package allows students to inspect solder joints and probe signals with standard 0.1-inch headers. The 5,980 LEs provide enough capacity for teaching CPU design, DSP algorithms, and digital communication concepts without overwhelming beginners. Quartus II Web Edition (free) supports the entire Cyclone family, so students can develop on EP1C6 boards and migrate the same code to Cyclone IV E or Cyclone 10 LP for their final projects. The part's low cost (relative to newer families) makes it ideal for classroom-laboratory budgets, and the mature toolchain has extensive tutorial materials available.

設計ノート
EP1C6T144I8 requires 3 separate supply rails: VCCINT at 1.5V for the core, VCCIO1-4 at 1.5V/1.8V/2.5V/3.3V for I/O banks, and an optional 2.5V PLL analog supply. Use low-ESR ceramic decoupling (0.1uF plus 10uF bulk) within 5mm of each VCC pin. According to the Cyclone datasheet, the device uses an internal linear regulator to derive core power, but VCCINT must still be supplied externally. Estimate ICCINT at ~100-300 mA depending on toggle rate and clock frequency; budget 500 mA total to be safe.
The 144-pin TQFP has a 1.0 mm lead pitch and 0.6 mm lead width - achievable with standard 4/4 mil (0.1/0.1 mm) SMT capability. Use a 4-layer PCB with a continuous ground plane under the device for signal integrity and thermal dissipation. JTAG and configuration pins (TMS, TCK, TDI, TDO, nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0, MSEL0-2) must be brought to test points or a JTAG header for in-circuit programming. Unused I/O pins should be left floating per Altera's recommendation; tying them low can increase ICCINT.
Three common pitfalls with EP1C6T144I8 designs: (1) Forgetting to connect MSEL[2:0] before power-up - the configuration mode is undefined and the device will not enumerate. (2) Driving JTAG signals from a 5V host when VCCIO is 3.3V - use a level shifter or set VCCIO to 3.3V and use 3.3V JTAG. (3) Using 5V signals directly on a 3.3V VCCIO bank - the absolute maximum I/O voltage is VCCIO+0.5V, so 5V on a 3.3V bank will damage the part. Use external level shifters (TXS0108E, SN74LVTH245) for 5V legacy interfaces.
LVDS pairs on the EP1C6T144I8 require 100-ohm differential termination between the LVDS pins. Route LVDS pairs with matched lengths (within 20 mil / 0.5 mm) and 100-ohm differential impedance. Avoid routing LVDS over plane splits - return path discontinuities cause common-mode noise that degrades signal integrity. For high-speed DDR interfaces using SSTL18 or SSTL2, follow the Altera Cyclone board design guidelines for skew matching (within 50 ps) and reference-voltage decoupling.
