EP1C3T100C6N Présentation
A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that can be re-programmed after manufacture to implement arbitrary digital logic. Within the broader taxonomy, an FPGA sits at the intersection of programmable logic devices (PLDs) and application-specific integrated circuits (ASICs), offering hardware-level parallelism, reconfigurability, and faster time-to-market than ASICs while delivering higher logic density than CPLDs. Cyclone family parts specifically target cost-sensitive, high-volume applications where ASIC NRE costs cannot be justified.
Key features of the EP1C3T100C6N include 13 embedded 18x18 multipliers suited for DSP functions such as FIR filters and FFTs, one PLL providing clock multiplication, phase shifting, and duty-cycle control, and on-chip configuration memory with active serial (AS), passive serial (PS), and JTAG programming modes. The device supports up to 20 global clock networks and hardware multipliers that are essential for digital signal processing pipelines.
The Cyclone architecture uses 4-input look-up tables (LUTs) as the fundamental logic element, paired with embedded M4K RAM blocks that can be configured as single-port, dual-port, or FIFO memory. Each M4K block provides 4,608 bits with parity support. The device interfaces with external configuration devices such as the EPCS1/EPCS4 serial flash for active serial configuration, supporting in-system programmability through JTAG.
Typical applications include consumer video processing, industrial control logic, automotive infotainment prototypes, low-cost PCI bridging, and educational development platforms. The 100-TQFP package and commercial temperature grade make it especially suitable for prototype boards, evaluation kits, and university labs where through-hole-friendly footprints simplify bring-up.
When designing with this part, pay close attention to I/O bank voltage compatibility, as mixing LVTTL and LVCMOS standards requires careful VCCIO assignment per bank. Decoupling requires at least 0.1 µF capacitors near every VCC pin plus bulk capacitors on each supply rail. Unused pins should be configured as inputs with weak pull-ups to reduce inrush current during configuration.

Applications typiques
EP1C3T100C6N convient pour 6 applications: Industrial Motor Control Logic, Low-Cost Video Processing Pipeline, PCI Bridge / Interface Logic, Educational FPGA Development Platform, Consumer Audio Signal Routing, Automotive Infotainment Prototyping.
Industrial Motor Control Logic
The EP1C3T100C6N fits motor-control designs requiring deterministic state machines, encoder decoding, and PWM generation. Its 2,910 LEs and 13 embedded 18x18 multipliers handle closed-loop PID computation, SVPWM modulation, and field-oriented control (FOC) at low to mid switching frequencies. The single PLL generates the precise clock base needed for synchronized PWM edges and tachometer sampling, while the 65 user I/Os accommodate Hall-sensor inputs, quadrature encoder channels, and gate-driver outputs. Compared with a microcontroller, the FPGA parallelizes encoder decoding and current sampling without jitter, reducing torque ripple.
Recommandé
Low-Cost Video Processing Pipeline
The EP1C3T100C6N suits entry-level video processing tasks such as color-space conversion, de-interlacing, and on-screen display (OSD) overlay. The 59,904 bits of M4K RAM serve as line buffers, while the 13 multipliers accelerate color-matrix math. Its 65 user I/Os handle ITU-R BT.656 video buses, sync signals, and SDRAM control. The 1.5 V core plus separate VCCIO banks let designers mix 3.3 V LVCMOS and 5 V-tolerant TTL interfaces on the same board, simplifying connection to legacy video ADCs and DACs without level shifters.
Recommandé
PCI Bridge / Interface Logic
The EP1C3T100C6N is widely used as a glue-logic PCI bridge or custom bus interface. Its 65 I/Os and support for 3.3 V PCI signaling in dedicated banks make it well-suited for prototyping custom peripherals, cardbus interfaces, or local-bus to PCI translation logic. The on-chip M4K RAM blocks can implement small FIFOs for bus buffering, while the 4-input LUTs handle address decoding and protocol translation. Engineers often use this part as a low-volume PCI target before committing to a hard ASIC.
Recommandé
Educational FPGA Development Platform
The EP1C3T100C6N is a workhorse for university digital-logic labs and hobbyist development boards thanks to its TQFP-100 footprint that is easy to hand-solder and breadboard-friendly. Quartus II Web Edition supports the device for free, allowing students to design Verilog or VHDL projects, run ModelSim simulations, and program via JTAG or Altera USB-Blaster cables. With 2,910 LEs and 13 multipliers, it accommodates teaching examples such as UART controllers, VGA drivers, simple CPUs, and FIR filters without exhausting logic resources.
Recommandé
Consumer Audio Signal Routing
The EP1C3T100C6N supports custom digital-audio routers, sample-rate converters, and effects processors in consumer audio gear. Its 13 multipliers enable biquad filter cascades and basic reverb algorithms, while M4K RAM blocks provide audio buffer storage. The 65 user I/Os comfortably handle I²S, SPDIF, and parallel DAC interfaces simultaneously, and the PLL generates low-jitter MCLK frequencies needed for 192 kHz audio paths. The Cyclone architecture's deterministic timing also helps eliminate audio pops and clicks during stream switching.
Recommandé
Automotive Infotainment Prototyping
Although the EP1C3T100C6N is commercial grade, designers use it in pre-production automotive infotainment and telematics prototypes where the industrial variant (EP1C3T100I7N) handles production runs. The FPGA can implement CAN bus controllers, GPS pre-processing, and LCD-timing logic in parallel, drastically reducing bill-of-material count versus discrete microcontroller + CPLD solutions. The 65 user I/Os accommodate RGB LCD panels, touch-screen controllers, and automotive LIN/CAN transceivers, while Quartus IP cores provide pre-verified CAN and LIN protocol stacks.

Principaux différenciateurs
- Higher density headroom in same family (vs EP1C3T100C8N)
- Industrial-temperature option available (vs EP1C3T100I7N)
- Cyclone family scalability (vs EP1C12Q240C6N)
Notes de conception
The EP1C3T100C6N requires three power rails: 1.5 V VCCINT for the core logic and two or more VCCIO supplies (typically 3.3 V, 2.5 V, or 1.8 V) for each I/O bank. Decouple every VCCINT and VCCIO pin with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, and add 10 µF bulk capacitors on each supply rail near the FPGA. Inrush current during configuration can exceed 500 mA; ensure the regulator has sufficient headroom and a soft-start ramp.
Route all JTAG signals (TDI, TMS, TCK, TDO) with 50 Ω controlled impedance and length-matched to within 1 inch. Place the JTAG header within 2 inches of the FPGA to avoid signal-integrity issues, and add 10 kΩ pull-ups on TMS, TDI, and nCONFIG per Altera's configuration guidelines. The TQFP-100 footprint has 0.5 mm lead pitch; use a 4-layer PCB with a dedicated ground plane beneath the device to provide a low-impedance return path for high-speed signals.
Avoid leaving JTAG pins floating: TMS and TDI require 10 kΩ pull-ups to VCCIO, and TCK requires a pull-down to ground if not driven externally. Unused user I/Os should be configured as inputs with weak pull-ups to prevent oscillation and reduce inrush during configuration. Mixing 5 V and 3.3 V signaling on the same bank without proper VCCIO assignment will damage the I/O cells; always consult the Cyclone family datasheet for bank-voltage compatibility before finalizing pin assignments.
