EP1C6TC144-8 - Cyclone FPGA, 5980 LEs, 144-TQFP | Intel
MPN: EP1C6TC144-8 ✗ Cuối đờiEP1C6TC144-8 Tóm tắt
An FPGA (Field-Programmable Gate Array) is a type of programmable logic device that allows designers to implement custom digital logic, state machines, DSP pipelines, and bus interfaces after PCB fabrication. FPGAs belong to the broader hierarchy of programmable logic -> ASIC prototyping devices -> digital semiconductor ICs. The Cyclone family is positioned as a low-cost, low-power FPGA family targeting high-volume applications such as consumer electronics, industrial control, and communications glue logic, sitting below Stratix devices in Altera's portfolio but above MAX CPLDs in logic density.
Key features of the EP1C6TC144-8 include 5,980 logic elements, 92,160 bits of embedded RAM organized as M4K blocks (4,608 bits each, 20 blocks total), 92 user I/O pins in this TQFP-144 package, two phase-locked loops for clock management, and support for LVTTL, LVCMOS, SSTL, and HSTL I/O standards. The device also features dedicated multiplier blocks capable of single 18x18 multiplication for DSP functions and supports external memory interfaces such as DDR SDRAM, QDR SRAM, and SDR SDRAM through dedicated interface circuitry.
The Cyclone architecture is built on a 1.5 V, 130 nm SRAM process with four-input look-up tables (LUTs) and embedded memory columns. Configuration is achieved through an SRAM-based bitstream loaded via JTAG, Active Serial (AS), or Passive Serial (PS) modes, with built-in decompression and CRC error detection. The 144-pin TQFP variant offers 92 user I/O pins with fine-grained LVDS support on selected pairs, making it suitable for cost-sensitive designs where BGA packages are not required.
Typical applications include industrial control and motor drives, consumer video processing, communications protocol bridging, low-cost DSP implementations, and PCI bus interfacing. The combination of low unit cost, mature tool support (Quartus II), and a non-BGA package makes the EP1C6TC144-8 well-suited for prototype runs, low-volume production, and through-hole-friendly board designs.
When designing with this device, plan for a 1.5 V core regulator with adequate transient response and a separate 3.3 V rail for the I/O banks. Power dissipation varies with logic utilization and toggle rate - estimate early using the PowerPlay analyzer in Quartus II. The Cyclone family has been marked EOL by Intel; for new designs, consider Cyclone II, Cyclone IV, or Cyclone V devices unless long-term continuity with legacy IP is required.

Ứng dụng tiêu biểu
EP1C6TC144-8 phù hợp cho 6 Áp dụngs: Industrial Motor Control, Consumer Video Processing, Communications Protocol Bridging, Low-Cost DSP Implementation, PCI Bus Interface Card, Legacy Design Continuity.
Industrial Motor Control
The EP1C6TC144-8 is well-suited for industrial motor control and drive signal generation. With 5,980 logic elements and 92 user I/Os in the 144-TQFP, the device can host multiple PWM channels, encoder interfaces, and field-oriented control (FOC) state machines while leaving headroom for serial protocol stacks such as RS-485 Modbus. The 92,160 bits of embedded M4K memory provide line buffers for current-loop sampling at typical 10 kHz rates. Designers appreciate the through-hole-friendly TQFP package, which simplifies prototype bring-up on 4-layer FR-4 boards used in motor drive PCBs. The -8 commercial speed grade is adequate for switching frequencies up to 100 kHz with proper pipeline scheduling. Estimated: 5,980 LEs at 50% utilization at 50 MHz toggle rate yields roughly 200-300 mW core power at 1.5 V.
Được đề xuất
Consumer Video Processing
Consumer video processing applications benefit from the EP1C6TC144-8's M4K memory blocks and PLL flexibility. The 92,160 bits of RAM support line buffers for video scaling, color-space conversion, and deinterlacing algorithms at standard-definition resolutions. Two PLLs provide independent clock generation for video pixel clocks and back-channel processing, eliminating the need for external clock generators on the PCB. The 144-TQFP package exposes 92 user I/Os, sufficient for 24-bit RGB buses, ITU-R BT.656 interfaces, and I2C control paths. The Cyclone architecture's 18x18 multiplier blocks can perform small filter taps for sharpening or noise reduction in real time. Estimated: a 720x480 deinterlacer using two line buffers consumes roughly 30 M4K blocks and 800 LEs, leaving room for on-screen display logic.
Được đề xuất
Communications Protocol Bridging
Protocol bridging between legacy and modern interfaces is a classic Cyclone use case. The EP1C6TC144-8 can simultaneously host UART, SPI, I2C, and PCI cores in the same fabric, providing glue-logic translation between, for example, an embedded host processor's SPI bus and a downstream CAN or RS-422 network. With 92 user I/Os, multiple parallel buses can be routed without external transceivers. The 1.5 V core and 3.3 V-tolerant I/O banks allow direct connection to legacy 5 V-tolerant PHYs through external resistively-clamped I/O. Designers can prototype in the 144-TQFP package on a through-hole-friendly PCB and migrate to the QFP-240 variant when more I/O is needed. Estimated: a quad-UART bridge plus PCI target core fits comfortably in 4,500 LEs and 40 M4K blocks.
Được đề xuất
Low-Cost DSP Implementation
Although the Cyclone family's embedded multipliers are less capable than modern DSP blocks, the EP1C6TC144-8 still performs well for low-cost DSP tasks such as FIR filtering, FFT pre/post-processing, and audio effects. The 18x18 multiplier capability supports single-cycle MAC operations, and with distributed arithmetic techniques the 5,980 LEs can implement 32-tap FIR filters with no external DSP chip. The two PLLs provide independent sample-rate conversion clocks, useful for audio interfaces that span from 8 kHz voice to 192 kHz hi-fi rates. The 144-TQFP package is compatible with hand-rework-friendly board assemblies, lowering prototype cost. Estimated: a 64-tap audio FIR at 48 kHz uses approximately 2,500 LEs and 16 M4K blocks for coefficient storage.
Được đề xuất
PCI Bus Interface Card
The EP1C6TC144-8 includes dedicated 3.3 V PCI-compliant I/O buffers and supporting logic, making it a natural fit for low-cost PCI add-in cards. At 33 MHz, the -8 speed grade is fully PCI-compliant, and the 92 user I/Os in the 144-TQFP package provide ample room for the 32-bit PCI bus plus application-specific I/O such as opto-isolated digital inputs or serial peripherals. Designers can implement a 32-bit, 33 MHz PCI target core in roughly 600-800 LEs with on-chip DMA engines, leaving the bulk of the device for the application logic. Estimated: a 33 MHz PCI target core with DMA occupies approximately 1,200 LEs and 12 M4K blocks; full card functionality fits within 4,000 LEs.
Được đề xuất
Legacy Design Continuity
Many long-life industrial, military, and avionics programs continue to require the original Cyclone family for proven IP cores and bitstream-level compatibility with deployed systems. The EP1C6TC144-8 provides that continuity - a verified 144-TQFP drop-in with the same 5,980-LE architecture and same Quartus II toolchain support that customers have used for over a decade. For programs that must demonstrate RoHS compliance, the EP1C6T144C8N variant offers the same die with Pb-free lead finish. The 144-TQFP package remains the preferred choice when legacy PCB layouts and through-hole assembly processes must be preserved. Estimated: legacy IP re-use typically requires zero LEs of recompilation overhead - only bitstream regeneration through Quartus II.

Ghi chú thiết kế
The EP1C6TC144-8 requires a clean 1.5 V core supply at up to approximately 500 mA for full logic utilization. Use a low-dropout regulator with at least 20% current headroom above the maximum expected core current, and place decoupling capacitors (0.1 uF plus 10 uF bulk) within 5 mm of each VCCINT pin. VCCIO banks should each have their own decoupling; mixing bank voltages requires careful isolation to prevent latchup.
The 144-pin TQFP package uses 0.5 mm pitch leads - trace escape routing requires vias in the land pattern or dog-bone fanout. Use a 4-layer PCB with continuous ground and power planes for signal integrity; route all clock and DQS signals first with controlled impedance. Place the EPCS configuration memory adjacent to the FPGA with the DATA and DCLK traces kept short and matched within 25 mm.
Do not apply 3.3 V signals to a 1.5 V VCCIO bank - this damages the I/O buffers. Confirm that all banks supplying 5 V-tolerant interfaces use the 3.3 V VCCIO setting. The original Cyclone family does not support hot-socketing; ensure power rails ramp monotonically and that nCONFIG is held low until all supplies are stable.
Estimated: at full 5,980-LE utilization with 100% toggle rate on all 92 I/Os at 100 MHz, the EP1C6TC144-8 dissipates approximately 1.0-1.5 W from the 1.5 V core. The 144-TQFP package thermal resistance is approximately 30 C/W junction-to-ambient with standard 4-layer PCB layout, so the junction temperature rise above ambient stays below 45 C in normal lab conditions. No external heatsink is required, but ensure airflow in enclosed industrial enclosures.
