EPC1C3T144C8 - Cyclone FPGA 2,910 LEs 144-TQFP C8 | Intel
MPN: EPC1C3T144C8 ✗ Cuối đờiEPC1C3T144C8 Tóm tắt
A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, embedded memory, and I/O cells that can be re-programmed post-manufacturing to implement arbitrary digital functions. FPGAs sit hierarchically between fixed-function ASICs (highest performance, highest NRE) and microcontrollers (lowest flexibility, lowest unit cost at high volume), occupying the niche where parallelism, custom datapaths, and rapid design iteration are required. The Cyclone family was Altera's (now Intel FPGA's) low-cost, low-power answer to this niche, optimized for glue logic, consumer electronics, and industrial control.
The EPC1C3T144C8 features 2,910 logic elements backed by 13 embedded 18x18 multipliers and 59,904 bits of embedded RAM distributed across M4K memory blocks. It offers 104 user I/O pins supporting LVTTL, LVCMOS, SSTL, and differential I/O standards, four phase-locked loops (PLLs) for clock management, and a low-power 1.5V core operating from a 0.13um process. Configuration is via passive serial (PS), active serial (AS), and JTAG modes, supported by Altera EPCS configuration devices.
Architecturally, the Cyclone device combines a fabric of LABs (Logic Array Blocks, each containing 10 LEs) with row and column interconnects, an embedded memory array, and multiplier blocks adjacent to the RAM to enable DSP-style operations. The 1.5V core with I/O ring flexibility and four PLLs allow designers to synthesize multiple clock domains from a single reference, while the 13 multipliers support up to 13 concurrent 18-bit MAC operations.
Typical applications include audio/video processing front-ends, industrial motor control and glue logic, video bridging and format conversion, and embedded protocol bridging (I2C, SPI, UART, parallel interfaces) in consumer and industrial products. The 144-TQFP package supports conventional SMT assembly on 4-layer PCBs without requiring BGA-class PCB fabrication.
When designing with this device, use the Altera Quartus II design suite (the modern toolchain is Intel Quartus Prime) and select the EP1C3 device family. Plan for configuration memory with a serial configuration device such as EPCS4 or EPCS16, and validate timing closure with Quartus TimeQuest before committing the design to prototype.

Ứng dụng tiêu biểu
EPC1C3T144C8 phù hợp cho 6 Áp dụngs: Industrial Glue Logic Replacement, Video Format Conversion and Bridging, Motor Control and Drive Logic, Audio Processing and Mixing, Embedded Protocol Bridging, Low-Volume ASIC Replacement.
Industrial Glue Logic Replacement
The EPC1C3T144C8 is widely deployed as a replacement for clusters of 74-series TTL/CMOS glue logic in industrial control boards, where its 2,910 logic elements and 104 user I/O pins can absorb dozens of discrete logic chips into a single programmable device. The 144-TQFP package supports conventional SMT assembly without BGA-class PCB processes. With 4 PLLs, designers can synthesize multiple clock domains from one reference, and 59,904 bits of embedded RAM support small FIFO buffers for protocol bridging. This consolidation reduces BOM cost and PCB area while allowing field firmware updates.
Được đề xuất
Video Format Conversion and Bridging
The EPC1C3T144C8 is used in mid-range video bridging applications such as BT.656/BT.1120 to parallel RGB conversion, VGA timing generation, and low-resolution video scaling. Its 13 embedded 18x18 multipliers support real-time FIR filtering for chroma resampling, and 59,904 bits of embedded RAM hold line buffers and lookup tables. The 104 user I/O pins interface to video ADCs/DACs without external bus multiplexers. Cyclone's Quartus II IP library provides free reference designs for common video timing controllers, accelerating development versus discrete logic implementations.
Được đề xuất
Motor Control and Drive Logic
The EPC1C3T144C8 serves as the central control logic in industrial motor drives, implementing field-oriented control (FOC) state machines, PWM generation, and current-loop timing with deterministic latency. Its 2,910 LEs easily fit typical 3-phase PWM controllers and quadrature encoder interfaces, while the 13 multipliers support Clarke/Park transforms for sensorless control. The 144-TQFP package is rated for industrial-grade assembly and supports conventional thermal management. The 4 PLLs generate the high-frequency PWM carrier from low-frequency crystals.
Được đề xuất
Audio Processing and Mixing
The EPC1C3T144C8 is suitable for digital audio mixing consoles and effect processors where its 13 multipliers enable parallel biquad filter stages, and 59,904 RAM bits hold audio delay lines. The 104 user I/O pins interface to multiple I2S/TDM audio codecs simultaneously for multi-channel mixing. Cyclone's LVDS capability supports professional audio interfaces such as AES3/EBU. The Quartus II DSP Builder accelerates MAC-based filter design versus hand-coded HDL, shortening time-to-prototype for audio engineers new to FPGA development.
Được đề xuất
Embedded Protocol Bridging
The EPC1C3T144C8 is commonly used as a protocol bridge IC, converting between I2C, SPI, UART, parallel buses, and proprietary interfaces in industrial and consumer products. Its 104 I/O pins support multiple concurrent bus interfaces, while 59,904 bits of RAM buffer data between protocols of differing speeds. The Cyclone IP catalog provides free UART, I2C, and SPI controller cores. The 144-TQFP package simplifies field-replaceable module designs where legacy bus compatibility is required alongside modern peripheral connectivity.
Được đề xuất
Low-Volume ASIC Replacement
The EPC1C3T144C8 is widely used as an ASIC replacement in low-to-medium-volume products (typically below 50K units annual) where ASIC NRE costs cannot be amortized. Its 2,910 LEs and 144-TQFP package cover the complexity range of small custom ICs such as appliance controllers, instrument front-ends, and specialty industrial sensors. Designers benefit from zero NRE, instant prototype turnaround, and field-updatable logic. Migration to ASIC is straightforward later if volumes justify, since Quartus-synthesized netlists are portable to Altera HardCopy structured ASICs.

Ghi chú thiết kế
The EPC1C3T144C8 requires three separate supply rails: VCCINT (1.5V core), VCCA (2.5V PLL analog), and VCCIO (per bank, 1.5V/1.8V/2.5V/3.3V selectable). Use a low-dropout regulator such as the TI TPS7A4515 for VCCINT with a 22uF ceramic output capacitor placed within 5mm of the FPGA pins. Estimate core current at approximately 500 mA worst case with all RAM and multipliers active. Decouple every VCCIO pin with a 0.1uF X7R ceramic capacitor plus a 10uF bulk capacitor per bank.
The 144-pin TQFP package has 0.5mm lead pitch and 22mm x 22mm body size, allowing assembly on conventional 4-layer PCBs. Route all four PLL power pins (VCCA_PLL) with a guard ring of vias to a quiet ground island, and keep clock traces under 25mm with impedance-controlled 50-ohm routing. Provide four-layer stackup with continuous ground plane beneath the FPGA for return current and thermal dissipation. Avoid routing high-speed signals across the TQFP lead rows to minimize crosstalk.
Do not leave CONFIG_DONE or nSTATUS floating - the Cyclone family requires a 10k-ohm pull-up on each for reliable configuration. Failing to connect MSEL pins to the correct logic levels for the desired configuration mode is a frequent board bring-up issue: 00=AS, 01=PS, 10=JTAG-only, 11=fast AS. Verify with Quartus programmer before power-on. Also note that I/O bank voltages must not exceed 4.0V even momentarily during hot-plug events, as the absolute maximum diode clamp ratings are easily exceeded.
