EP1C6T144C8N - Cyclone FPGA 5980 LE 144-TQFP | Intel / Altera
MPN: EP1C6T144C8N ✓ פעילEP1C6T144C8N סקירה
An FPGA (Field Programmable Gate Array) is a reprogrammable semiconductor that lets engineers implement arbitrary digital logic - from simple state machines to soft processor cores - by configuring an on-chip array of look-up tables, flip-flops, and programmable interconnect. FPGAs sit in the broader taxonomy of programmable logic devices (PLD), above simple CPLDs in capacity and below ASICs in per-unit cost but with the crucial advantage of in-system reprogrammability. The Cyclone family specifically targeted low power and low cost per logic element, opening FPGAs to volume consumer and industrial markets previously served only by ASICs or microcontroller-based designs.
Key features of the EP1C6T144C8N include two PLLs for clock multiplication and phase shifting, dedicated 18x18 multipliers for DSP-style arithmetic, support for external memory interfaces including DDR SDRAM and FCRAM, and an active serial (AS) configuration interface compatible with low-cost EPCS configuration devices. The 144-TQFP package provides 98 usable I/O pins arranged in four I/O banks, allowing flexible mixed-voltage interfacing through bank-level VCCIO rails.
Typical applications include industrial control and factory automation backplanes, motor control and inverter drive boards, telecommunications line cards and protocol bridges, low-cost video processing pipelines, education and development kits, and replacement of legacy glue-logic ASICs where the original mask set is unavailable. Long product-life status and broad Quartus II tool support have made it a default choice for sustaining engineering.
When designing with the EP1C6T144C8N, engineers should plan for a 1.5 V core supply with separate VCCIO bank rails and observe the I/O bank voltage grouping rules documented in the Cyclone device handbook. Configuration memory must be loaded at every power-up from a non-volatile EPCS device or a JTAG/USB-Blaster programmer; the device does not retain configuration when powered down. Thermal management is straightforward thanks to the plastic TQFP package and modest static plus dynamic power dissipation.
This page synthesizes Cyclone family datasheet parameters, distributor stock and pricing snapshots, and drop-in same-footprint alternatives (C6/C7 speed grades, I-grade temperature variants, and 144-TQFP Cyclone I siblings) to help engineers compare, source, and sustain EP1C6T144C8N-based designs.

יישומים טיפוסיים
EP1C6T144C8N מתאים עבור 6 יישוםs: Industrial Motor Control, Telecommunications Line Cards and Protocol Bridges, Legacy Glue-Logic and ASIC Replacement, Education and FPGA Training Platforms, Low-Cost Video Processing Pipelines, Data Acquisition Front-Ends.
Industrial Motor Control
The EP1C6T144C8N fits industrial motor-control boards because its 5,980 logic elements, 2 PLLs, and 92 Kbits of embedded RAM provide enough capacity to host encoder decoding (QEP), PWM generation, and current-loop state machines in a single chip. The 98 user I/Os comfortably connect to multi-axis power-stage gate drivers, Hall sensors, and isolated communication transceivers. The Cyclone I 0.13 µm process keeps static power low, an important factor in always-on factory cabinets.
מומלץ
Telecommunications Line Cards and Protocol Bridges
In telecom line-interface cards, the EP1C6T144C8N serves as a low-cost protocol-bridging FPGA, mapping between legacy T1/E1 framers, I²S audio buses, and Ethernet MII/RMII PHYs. Its 275 MHz core plus 2 PLLs can drive 100 Mbps MII comfortably, while the 98 I/Os handle multiple serial streams with hardware-accelerated framing. The commercial 0°C to +85°C range suits controlled-environment central-office deployments where industrial-grade parts are unnecessary.
מומלץ
Legacy Glue-Logic and ASIC Replacement
The EP1C6T144C8N is a workhorse replacement for aging 144-TQFP ASICs and discrete 74-series glue logic in long-life industrial platforms. Its SRAM-based configuration lets engineers re-spin functionality in software without respinning the silicon, dramatically reducing sustaining-engineering cost. The Cyclone I family's decade-long production history and Quartus II Web Edition free toolchain support mean designs can be maintained without expensive software licenses.
מומלץ
Education and FPGA Training Platforms
Universities and FPGA training labs favor the EP1C6T144C8N because its 5,980 logic elements are large enough to host a Nios II soft processor and meaningful student projects, yet small enough that Quartus II Web Edition (free) can compile bitstreams within minutes. The 144-TQFP package is breadboard-friendly with 0.5 mm pitch adaptors, and the abundant EP1C6 development kit reference designs accelerate student onboarding. Long product-life assurance also lets universities stock lab kits with confidence.
מומלץ
Low-Cost Video Processing Pipelines
The EP1C6T144C8N supports entry-level video processing such as NTSC/PAL decoding, on-screen-display overlay, and color-space conversion in cost-sensitive consumer equipment. Its 98 I/Os accommodate parallel ITU-R BT.601 video buses plus control peripherals, and the 92 Kbits of block RAM buffer line-store memory without external SRAM. The 1.5 V core with 3.3 V-tolerant I/Os makes it easy to interface directly to legacy video ADCs and DACs.
מומלץ
Data Acquisition Front-Ends
The EP1C6T144C8N is a strong fit for multi-channel data-acquisition front-ends where it manages timing-critical ADC/DAC handshake logic, FIR filter pre-processing, and DMA transfers to a host MCU. The 2 PLLs generate multiple simultaneous sample clocks, while 92 Kbits of block RAM implement per-channel ping-pong buffers. The commercial temperature range suits benchtop and laboratory instruments, and the same PCB can host the EP1C6T144I7N industrial variant for field-deployed units.

הערות תכנון
The EP1C6T144C8N requires a regulated 1.5 V VCCINT rail capable of supplying transient currents up to ~500 mA during configuration, plus four independent VCCIO rails (1.5 V / 1.8 V / 2.5 V / 3.3 V) for I/O banks. Decouple each VCCINT pin with a 0.1 µF X7R ceramic placed within 5 mm of the pin, and bulk-decouple each VCCIO bank with 10 µF tantalum plus 0.1 µF ceramic. The PLL analog supply (VCCA_PLL) should be filtered through a ferrite bead and decoupled with 10 µF + 0.1 µF to suppress jitter.
Route JTAG (TCK, TMS, TDI, TDO) as a daisy-chain with 22 Ω series-termination resistors near the driver; keep the chain stub length under 25 mm to preserve signal integrity. Place the EPCS configuration flash within 50 mm of the ASDO/nCSO/DATA pins and use a 4-layer PCB with continuous ground plane under the TQFP footprint. Leave a 2 mm copper keep-out around the TQFP body for inspection access, and flood unused I/O bank area with VCCIO for shielding.
Do not leave MSEL[2:0] floating; tie them through 10 kΩ resistors to the correct configuration-mode logic level (AS mode = 000, JTAG-only = 101). The CONF_DONE and nSTATUS pins are open-drain and require external 10 kΩ pull-ups to VCCIO. Avoid using the EP1C6T144C8N in new designs requiring >85°C ambient operation - select EP1C6T144I7N (industrial) instead. Configuration failures on first prototypes are most often due to missing VCCA_PLL decoupling or incorrect MSEL strapping.
