A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable routing, and dedicated I/O cells that can be re-programmed in-system to implement arbitrary digital logic. FPGAs sit at the top of the programmable logic hierarchy alongside CPLDs, and are widely used as prototyping vehicles, glue logic, DSP accelerators, and pre-silicon verification platforms. The Cyclone family occupies the low-cost end of that hierarchy, optimized for ASIC replacement in volume production.
Key features of the EP1C3T100CB include 2,910 logic elements, 13 embedded 4-Kbit M4K RAM blocks (totalling 59,904 RAM bits), one PLL for clock management, and a flexible I/O structure supporting LVTTL, LVCMOS, SSTL-2, and SSTL-3 standards. Configuration is loaded through an industry-standard passive-serial, active-serial, or JTAG interface, enabling fast in-system programming. The 100-pin TQFP (1.0 mm pitch, 14 × 14 mm body) provides a 65-pin user I/O count after subtracting JTAG, configuration, power, and ground pins.
The architecture is based on a four-input look-up table (LUT) fabric with embedded multiplier-free DSP-style logic and dedicated carry chains for arithmetic. Embedded RAM blocks can be configured as simple dual-port, true dual-port, or FIFO memory, supporting buffer and small-packet processing tasks. The Cyclone series pioneered Altera's low-cost FPGA positioning that later evolved into the Cyclone II, III, IV, and V families on finer process nodes.
Typical applications include industrial control logic, low-density glue logic, communications protocol bridging, consumer electronics display controllers, and pre-silicon ASIC prototyping. The 100-TQFP package makes it suitable for through-hole-friendly prototyping boards and low-volume production assemblies that do not require BGA-level integration.
When designing with this part, note that it is in production but classified as a mature-product line; new designs should compare it against Cyclone II, III, or Cyclone IV equivalents for long-term availability. Configuration data must be loaded at every power-up from an external flash memory or download cable.

典型應用
EP1C3T100CB 適用於 6 應用s: Industrial Control Logic, Communications Protocol Bridging, Consumer Display Controllers, ASIC Pre-Silicon Prototyping, Glue Logic Replacement, Educational FPGA Trainer Boards.
Industrial Control Logic
The EP1C3T100CB suits industrial control logic applications where 2,910 logic elements provide enough capacity for state-machine-driven motor control, sensor aggregation, and HMI scanning without an external ASIC. Its 100-TQFP package with 1.0 mm pitch is friendly to two-layer industrial PCBs that avoid BGA assembly cost. The on-chip PLL generates deterministic clocks for encoder sampling, and the 59,904 bits of embedded RAM buffer command queues between the FPGA and downstream MCUs. According to the Cyclone datasheet, the 65 user I/Os support LVTTL and 24 mA drive strength, sufficient for direct opto-coupler interfacing in 24 V industrial environments.
推薦
Communications Protocol Bridging
The EP1C3T100CB acts as a low-latency protocol bridge between legacy and modern interfaces such as UART-to-SPI, I2C-to-parallel, or CAN-to-Ethernet, thanks to its flexible I/O standard support and 2,910 logic elements. The 100-TQFP pinout exposes enough LVTTL/LVCMOS pins to run four independent UART channels plus a high-speed SPI master concurrently. The embedded M4K RAM blocks buffer packets between asynchronous clock domains while the single PLL cleans reference jitter. Engineers commonly use this density for protocol conversion in telecom line cards and serial-to-IP gateways.
推薦
Consumer Display Controllers
Consumer display controllers built on the EP1C3T100CB can drive small TFT panels, character LCDs, or LED matrices through PWM generators implemented in the 2,910 logic elements. The 100-TQFP's 65 user I/Os comfortably handle 8-bit RGB interfaces plus control signals for QVGA panels. Embedded M4K blocks store lookup tables for gamma correction and colour-space conversion without consuming external memory. The on-chip PLL derives pixel clocks from a low-frequency reference, reducing external oscillator cost in cost-sensitive consumer electronics.
推薦
ASIC Pre-Silicon Prototyping
Pre-silicon ASIC prototyping on the EP1C3T100CB allows engineers to validate register-transfer-level designs on real hardware before committing to mask costs, especially when the target ASIC falls within the 2,910-LE complexity envelope. The 100-TQFP package is breadboard-friendly, simplifying bring-up with standard 0.1-inch headers. Cyclone devices integrate seamlessly with Altera's SOPC Builder and Qsys toolchains for embedded Nios II soft-core verification. According to the Cyclone family datasheet, JTAG-based debug via SignalTap II is fully supported on this part.
推薦
Glue Logic Replacement
Replacing discrete 74-series glue logic with the EP1C3T100CB consolidates dozens of small logic packages into a single programmable device, simplifying PCB layout and reducing BOM count. The 65 user I/Os accommodate address decoding, bus arbitration, interrupt steering, and chip-select generation across multiple peripherals. The 100-TQFP body occupies roughly the same board area as four SOIC-16 packages while delivering higher reliability and field-upgradable functionality through SRAM-based configuration.
推薦
Educational FPGA Trainer Boards
Educational FPGA trainer boards built around the EP1C3T100CB expose students to real Verilog or VHDL design flows using a low-cost 100-TQFP part that is easy to solder and rework. The 2,910 logic elements are sufficient for labs covering finite state machines, FIFOs, simple CPUs, and basic DSP. The on-board EPCS configuration memory supports standalone operation without a host PC, enabling embedded learning platforms. According to the Cyclone datasheet, the device's JTAG chain allows interactive logic analyser debugging with SignalTap II.

設計說明
The EP1C3T100CB requires three separate supply rails: VCCINT (1.5 V core), VCCIO1-4 (per-bank I/O voltage, typically 3.3 V or 2.5 V), and a common GND. Decouple each VCCINT pin with a 0.1 µF ceramic capacitor placed within 5 mm of the package, and add a 10 µF bulk tantalum or ceramic capacitor near each VCCIO bank. Insufficient decoupling causes configuration failures and jitter on high-speed LVTTL outputs.
Route configuration signals (DCLK, DATA0, nCONFIG, nSTATUS, CONF_DONE) away from high-speed switching nets and keep their traces under 50 mm to avoid signal-integrity issues during configuration. The MSEL0 and MSEL1 pins must be tied to VCCIO or GND through 1 kΩ resistors; floating MSEL pins cause the device to power up in an undefined mode and fail to configure.
The EP1C3T100CB is supported only by Quartus II software up to version 13.0sp1; the Quartus Prime Standard and Pro editions do not support the original Cyclone family. Engineers migrating to newer toolchains must retain a legacy Quartus II installation. Additionally, this part is SRAM-based and loses configuration when power is removed — always pair it with an Altera EPCS serial configuration device for standalone operation.
Place the JTAG header (TDI, TMS, TCK, TDO) at the board edge for easy programming access, and add 4.7 kΩ pull-ups on TMS, TDI, and TCK plus a 4.7 kΩ pull-up on nCONFIG per the Cyclone handbook reference design. Keep JTAG traces short (<100 mm) and avoid routing them next to switching power or clock lines to prevent debug probe noise coupling.
