EP1C3T100C6 概要
A Field-Programmable Gate Array (FPGA) is a programmable logic device containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, all of which can be reconfigured by the user after manufacture. Within the broader semiconductor taxonomy, an FPGA sits between a general-purpose microcontroller and a fixed-function ASIC: faster and more parallel than a microcontroller for parallel data-path tasks, yet cheaper and more flexible than an ASIC at low-to-medium volumes. The Cyclone I family was Altera's first low-cost FPGA line and is hierarchical under: FPGA -> programmable logic device -> logic IC -> integrated circuit -> semiconductor.
Key features of the EP1C3T100C6 include 65 user I/O pins on the TQFP-100 package, 1.5 V core voltage with 3.3 V I/O tolerance, 130 nm process technology, JTAG-based in-system programming via the Altera ByteBlaster or USB-Blaster, support for LVTTL, LVCMOS, SSTL-2, and SSTL-3 I/O standards, and an operating junction temperature of 0 C to +85 C (commercial grade, indicated by the C6 speed-grade suffix meaning -6 speed grade, commercial temperature range). The exposed thermal pad on the bottom of the TQFP package helps dissipate the modest power dissipation typical of this small device.
From an architectural perspective, the Cyclone I device uses 4-input look-up tables (4-LUTs) as its basic logic element, embedded M4K memory blocks of 4 Kbits each (delivering 13 M4K blocks / ~52 Kbits usable per block family-wide), and a unified interconnect fabric called MultiTrack that minimizes routing congestion. The single PLL provides clock multiplication, division, and phase shifting, which is sufficient for most glue-logic and protocol-bridge designs but limits the device compared to larger Cyclone variants with multiple PLLs.
Typical applications include digital I/O expansion for microcontrollers, custom peripheral bridging (UART, SPI, I2C, or parallel bus glue logic), simple video or display timing controllers, low-cost industrial control boards, educational FPGA development platforms, and prototype ASIC replacement for designs later migrating to a structured ASIC or Cyclone II/III/IV. The combination of 100-pin TQFP (hand-solderable and breadboard-friendly via adapter) and Quartus II Web Edition software support makes it a popular choice in academic and maker communities.
When designing with the EP1C3T100C6, observe the 1.5 V VCCINT supply and 3.3 V VCCIO I/O supply requirement with proper decoupling (100 nF and 10 uF bulk near each supply pin). Programming via JTAG requires a 10-pin header wired per the Altera ByteBlaster II / USB-Blaster pinout. Unused I/O pins should be left floating or configured as outputs driving low to minimize switching current.

主な用途
EP1C3T100C6 の用途: 6 件s: Microcontroller I/O Expansion and Glue Logic, Custom Protocol Bridge (UART / SPI / I2C / Parallel), Video Timing Controller and Simple Display Driver, Low-Cost Industrial Control and Sensor Aggregation, Educational FPGA Development and University Labs, ASIC Prototype Replacement Bridge.
Microcontroller I/O Expansion and Glue Logic
The EP1C3T100C6 is well suited to microcontroller I/O expansion and custom glue logic because its 2,910 logic elements and 65 user I/O pins let designers consolidate scattered 74HC/74LVX logic into a single programmable device. With a 405.2 MHz internal frequency and 1.5 V core, it can implement fast parallel-to-serial converters, custom peripheral bridges, and address decoding at clock rates far above what 8-bit microcontrollers deliver. The 100-pin TQFP is hand-solderable for low-volume industrial control boards. Designers pair this Cyclone I device with an STM32 or PIC32 host; the FPGA handles DMA-style data shuffling while the MCU runs the application stack.
おすすめ
Custom Protocol Bridge (UART / SPI / I2C / Parallel)
Protocol bridging is a classic Cyclone I EP1C3T100C6 application because the device can implement multiple serial protocols simultaneously with deterministic latency. With one PLL providing flexible clock generation, designers can lock the FPGA to an external reference and produce any internal baud-rate clock needed for UART, SPI master/slave, I2C, or proprietary parallel buses. The 59,904 bits of embedded M4K RAM act as a FIFO between asynchronous clock domains, eliminating the need for external SRAM. This is widely used in legacy industrial equipment that needs to translate between RS-232, RS-485, and modern Ethernet-attached controllers.
おすすめ
Video Timing Controller and Simple Display Driver
The EP1C3T100C6 fits simple video timing controller roles such as VGA 640x480@60 Hz, LCD TFT timing generation, and LVDS-to-parallel RGB conversion because the 405.2 MHz internal frequency easily handles pixel clocks up to 108 MHz with margin. The 65 user I/O support the 24-bit RGB bus plus HSYNC, VSYNC, DE, and clock signals to drive small TFT panels. Designers implement color-space conversion (YCbCr to RGB) or gamma correction in fabric, and use one M4K block per scanline as a small framebuffer for on-screen display overlays. Pair this with a small 3.5 inch TFT panel for low-cost HMI products.
おすすめ
Low-Cost Industrial Control and Sensor Aggregation
Industrial control and sensor aggregation boards use the EP1C3T100C6 because of its deterministic latency, 65 I/O count, and Quartus II support for hardware state machines. Designers implement Modbus RTU, CAN, or custom field-bus slaves alongside digital input debouncing, PWM generation, and quadrature encoder counters all on one device. The 1.5 V core at 130 nm draws modest power suitable for enclosed control cabinets. Industrial users select the EP1C3T100I7 variant when -40 C operation is required; otherwise the EP1C3T100C6 in commercial temperature range is sufficient for indoor enclosures.
おすすめ
Educational FPGA Development and University Labs
The EP1C3T100C6 remains a popular choice in educational and university lab settings because the 100-pin TQFP is breadboard-friendly via a TQFP-to-DIP adapter, the 2,910 logic element capacity supports Verilog/VHDL coursework projects of meaningful complexity, and the legacy Quartus II Web Edition toolchain is freely available. Students can implement RISC-V soft cores, simple CPUs, UART controllers, and VGA drivers within a single lab session. The Altera Cyclone Device Family datasheet (94 pages) provides full reference material for academic exercises in digital design, computer architecture, and embedded systems courses.
おすすめ
ASIC Prototype Replacement Bridge
Engineers use the EP1C3T100C6 as a fast-turnaround ASIC prototype before committing to a structured-ASIC or full-custom mask set, because the same Quartus II HDL code can later be retargeted to a Cyclone II / Cyclone III / Cyclone IV device for production. The 100-pin TQFP lets a 2,910 LE design be verified in-system at full speed, exposing logic bugs that simulation cannot catch. Once the design is stable, designers migrate to a larger Cyclone IV EP4CE6E22 for production; this de-risks the schedule and lets marketing pre-sell against a known FPGA reference platform. For long-life products, migrate again to a hard-copy structured ASIC once volumes exceed ~50K units.

設計ノート
The EP1C3T100C6 requires two supply rails: VCCINT = 1.5 V for core logic and PLL, and VCCIO = 1.5 V / 1.8 V / 2.5 V / 3.3 V selected per I/O bank. Decouple each VCCINT and VCCIO pin with a 100 nF X7R ceramic capacitor placed within 100 mils (2.5 mm) of the pin, and add one 10 uF bulk ceramic or low-ESR tantalum capacitor per supply rail. Estimated: with all 65 I/O at 50 percent toggle and 50 MHz, total VCCINT current is approximately 100 to 150 mA; VCCIO depends on load but typically 20 to 50 mA per bank. Power sequencing is not required because VCCIO must not exceed VCCINT by more than 3.0 V during ramp.
Lay out the 100-pin TQFP with a 4-layer PCB (signal / ground / power / signal). Use a continuous ground plane on layer 2 directly under the device, and route VCCINT and VCCIO traces with at least 20 mil width on layer 4. Keep JTAG signals (TCK, TMS, TDI, TDO) short and length-matched within 100 mils; place a 10-pin 0.1 inch JTAG header at the board edge for the ByteBlaster II or USB-Blaster cable. Leave the exposed thermal pad on the bottom of the TQFP soldered to a 5 mm x 5 mm copper pour for modest thermal relief.
Do not program the EP1C3T100C6 with Quartus Prime 14.0 or later - Cyclone I support was dropped after Quartus II 13.0sp1. Retain a legacy Quartus II installation if you need to compile new bitstreams. Avoid mixing 1.5 V and 3.3 V on the same I/O bank - VCCIO sets the entire bank voltage. Finally, configure unused I/O pins as outputs driving low (or as inputs with weak pull-up enabled) in your Quartus pin assignment file to minimize leakage and switching current on unused pins.
For designs using the LVDS or SSTL I/O standards, route the differential pair (or clock pair) with 100 ohm differential impedance and keep length matching within 10 mils. Place a 100 ohm differential termination resistor within 200 mils of the receiver pin when using LVDS inputs. For 50 MHz and below, standard FR-4 stackup with 6 mil traces works; above 100 MHz consider 4 mil traces with continuous ground reference. Add a source-series 33 ohm resistor on clock outputs driving long external traces to dampen reflections.
コンプライアンス情報
Compliance data not present in the verified web data; the EP1C3T100C6 is not AEC-Q100 qualified (it is a commercial / industrial FPGA, not an automotive-grade part). For RoHS-compliant designs choose the EP1C3T100C6N or C8N N-suffix variant.
