EP1C3T100C8 - Cyclone FPGA 2,910 LEs TQFP-100 | Intel | EOL
MPN: EP1C3T100C8 ✗ Cuối đờiEP1C3T100C8 Tóm tắt
A field-programmable gate array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable routing, and dedicated hard IP such as block RAM, PLLs, and I/O serdes. FPGAs occupy the middle ground between fixed-function ASICs and software-driven microcontrollers: the silicon is generic, but designers define every flip-flop, LUT, and interconnect at compile time using HDL bitstreams. Within the broader taxonomy, the EP1C3T100C8 sits at FPGA & CPLD > programmable logic > semiconductor IC.
Key specifications include 13 M4K RAM blocks (4 Kbits each, plus 512 parity bits) totaling 59,904 memory bits, one general-purpose PLL for clock synthesis and phase shifting, embedded multipliers are not present on EP1C3 devices, and 65 LVDS-pair-capable or 3.3 V-tolerant user I/Os. Configuration is supported via active serial (AS), passive serial (PS), and JTAG modes, allowing the device to boot from low-cost EPCS configuration memories or be programmed in-circuit through the JTAG header.
Architecture-wise, the Cyclone I family uses 4-input look-up tables (LUT4) per logic element with a dedicated register and carry chain for arithmetic, plus per-LAB control signals. The 0.13 µm process with copper interconnect minimizes dynamic power, while the 1.5 V core VCCINT keeps static leakage low for cost-sensitive, high-volume applications. Die size and routing density are tuned for designs in the 2K-3K LE range such as glue logic, I/O expansion, custom peripherals, and protocol bridges.
Typical applications include industrial control glue logic, low-cost I/O expansion and bridging (UART/SPI/I2C to parallel), legacy peripheral replacement, motor-control co-processors, educational and prototyping boards, video/display formatting front-ends, and consumer-electronics glue functions where a small, deterministic logic device replaces discrete 74-series logic. The EP1C3T100C8 is also widely used as a firmware-controlled test fixture controller in production lines.
Designers should note that this device is EOL with last-time-buy status per Intel PDN1810; new designs are directed to Cyclone IV, Cyclone V, or Cyclone 10 families. For existing production, ensure the 1.5 V core is generated by a low-noise LDO and that JTAG chain integrity is verified before in-system programming. I/O bank VCCIO must be matched to the driven/receiving logic level (1.5 V, 1.8 V, 2.5 V, or 3.3 V) to prevent bus contention and long-term reliability issues.

Ứng dụng tiêu biểu
EP1C3T100C8 phù hợp cho 6 Áp dụngs: Industrial Glue Logic Replacement, Custom Peripheral Bridge (UART/SPI/I2C to Parallel), Legacy Peripheral Replacement and Form-Fit-Function Drop-In, Educational and Prototyping Boards, Motor-Control Co-Processor, Production Test Fixture Controller.
Industrial Glue Logic Replacement
The EP1C3T100C8's 2,910 LEs and 100-pin TQFP footprint make it a one-chip replacement for entire boards of 74-series glue logic in industrial controllers. Its 65 user I/Os handle address decoding, bus arbitration, and interrupt steering at deterministic sub-25 ns propagation delays, while the 1.5 V core keeps power dissipation under 200 mW for fanless DIN-rail enclosures. Designers can migrate legacy discrete logic schematics into a single Quartus II project, cutting PCB area by 60-80% and BOM lines by dozens. The commercial 0C to +85C temperature range covers most indoor factory environments when paired with industrial-grade peripheral ICs.

Custom Peripheral Bridge (UART/SPI/I2C to Parallel)
With 59,904 bits of M4K block RAM and 8 global clock networks, the EP1C3T100C8 is well suited as a multi-protocol peripheral bridge that converts UART, SPI, and I2C traffic into a parallel bus for legacy microcontrollers. The 13 M4K blocks implement 16-byte-deep FIFOs per channel, while the 1 PLL derives domain-crossing clocks for each interface. JTAG-based in-system programming simplifies field firmware updates over the same JTAG header used for boundary-scan. Cyclone I's 0.13 µm process gives deterministic timing that ASIC replacement designs require when emulating discrete UARTs (16550) or SPI peripherals in industrial PCs.

Legacy Peripheral Replacement and Form-Fit-Function Drop-In
The EP1C3T100C8 is widely used as a firmware-driven replacement for obsolete peripheral ICs whose original silicon is no longer available. Its 100-pin TQFP and 65 user I/Os match many 1990s-era peripheral footprints, allowing drop-in board replacements where only the FPGA bitstream is rewritten. Designers can replicate custom ASIC functions, video sync separators, or proprietary bus controllers while keeping the original PCB. The 1.5 V core plus selectable VCCIO banks (1.5/1.8/2.5/3.3 V) ensures compatibility with both legacy 5 V-tolerant buses via external resistors and modern 1.8 V LVCMOS peripherals on the same board.

Educational and Prototyping Boards
University digital-logic labs and FPGA training courses have long standardized on the EP1C3T100C8 because the 100-pin TQFP is hand-solderable for student assembly and the 2,910 LE capacity is large enough for full RISC-V or MIPS soft-core implementations, yet small enough to fit in low-cost Altera/Intel DE-series and Terasic training boards. The free Quartus II Web Edition supports the entire Cyclone I family, removing licensing barriers for coursework. With 13 M4K RAM blocks and 1 PLL, students can implement UARTs, VGA controllers, and simple CPUs in a single device while learning HDL design flows.

Motor-Control Co-Processor
The EP1C3T100C8 serves as a deterministic co-processor next to a microcontroller in BLDC and stepper motor drives, offloading PWM generation, encoder quadrature decoding, and field-oriented control loops at sub-microsecond jitter. Its 1 PLL multiplies the encoder reference clock to the PWM switching frequency (typically 20-100 kHz), while 13 M4K blocks store sine tables and current-loop history. The 65 user I/Os accommodate 3-phase gate drivers, Hall sensors, and RS-485 feedback without an I/O expander. Industrial-temperature grade (-40C to +100C) variants like the EP1C3T100I7N are preferred for under-hood and outdoor motor installations.

Production Test Fixture Controller
In-circuit test (ICT) and functional test fixtures use the EP1C3T100C8 as a flexible pattern generator and boundary-scan controller. The 65 user I/Os drive test pins directly, while JTAG mode enables live reconfiguration of test patterns per SKU without changing fixture hardware. The 1.5 V core and 8 global clocks provide deterministic timing critical for sub-microsecond test windows, and the LVDS-capable I/Os support high-speed differential probing. Engineers can store hundreds of test patterns in external EPCS flash and load them on-the-fly via the JTAG or AS configuration port.

Ghi chú thiết kế
The EP1C3T100C8 requires a clean 1.5 V VCCINT supply with a tolerance of +/-5% and a 3.3 V, 2.5 V, 1.8 V, or 1.5 V VCCIO per bank. Use a low-dropout regulator (e.g., TI TPS7A4515 or equivalent) for VCCINT, and place 0.1 µF + 10 µF decoupling capacitors within 5 mm of each VCCINT pin per the Cyclone I datasheet decoupling recommendations. Estimated: with all 65 user I/Os toggling at 100 MHz, dynamic current peaks can reach 300-400 mA on VCCINT; budget the LDO for at least 500 mA. For PLL supplies (VCCA_PLL, VCCD_PLL), use a pi-filter (ferrite bead + 10 µF + 0.1 µF) to isolate PLL noise from the core supply.
Route configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, MSEL0, MSEL1, DATA0) away from switching I/O signals to prevent corruption during configuration. Place the EPCS configuration memory within 25 mm of the FPGA DATA0/DCLK traces for AS mode and keep those traces impedance-controlled to 50 Ω. The 100-pin TQFP has a 0.5 mm pitch; use 0.15 mm trace/space rules and a 4-layer PCB with a dedicated ground plane for return paths. JTAG chain integrity should be verified with the Quartus II programmer before any production programming step.
Do not mix 5 V signals directly with the EP1C3T100C8 I/O banks - the absolute maximum VCCIO is 4.6 V and any over-voltage will permanently damage the device. Use a level translator (e.g., SN74AVC8T245) for 5 V-to-3.3 V interfacing, or a resistive divider with 10 kΩ / 20 kΩ for low-speed inputs. Avoid driving JTAG TCK faster than 25 MHz; higher rates can cause boundary-scan failures on long JTAG chains. When migrating from EP1C3T100C8 to EP1C3T100I7N, verify the temperature range in the design specification - industrial parts may require a different thermal pad layout and copper-pour sizing.
For 100-pin TQFP (14x14 mm, 0.5 mm pitch), use a 4-layer stack-up with signal-top, GND-plane, power-plane, signal-bottom to provide continuous return paths for high-speed LVDS and clock traces. Place VCCIO and VCCINT decoupling as a 0.1 µF X7R capacitor directly under each power pin and a 10 µF bulk capacitor within 10 mm. Route clock inputs (CLK0-CLK1) as microstrip with 50 Ω impedance and length-matched to within 200 mils if used as a differential pair. Keep PLL analog supplies (VCCA_PLL, VCCD_PLL) on a quiet island of the power plane, separated from digital VCCINT by at least 3 mm.
