EP1C6T144LI6 - Cyclone FPGA 6K LE, 144-LQFP, Industrial | Altera
MPN: EP1C6T144LI6 ⚠ Lần mua cuốiEP1C6T144LI6 Tóm tắt
A Field Programmable Gate Array (FPGA) is a semiconductor device whose digital logic fabric, interconnect, and I/O cells can be reconfigured after manufacture by loading a user-defined bitstream into on-chip SRAM configuration memory. FPGAs sit above microcontrollers in the digital logic hierarchy, providing massively parallel hardware execution with deterministic timing, and below ASICs in terms of unit cost. Cyclone was Altera's first family optimized for low-power, low-cost applications such as consumer electronics, automotive infotainment, and industrial control, displacing CPLDs and small gate arrays in many designs. The 'T144' suffix denotes the TQFP-144 package, the 'L' suffix indicates a lead-free finish, the 'I' indicates industrial temperature range, and the '6' indicates speed grade 6.
Key features include support for up to 185 user I/O pins across four I/O banks, two dedicated phase-locked loops for clock synthesis, embedded 4-Kbit RAM blocks (M4K) for distributed buffering, support for LVDS, LVTTL, LVCMOS, SSTL-2, SSTL-3, and PCI I/O standards, and configuration via serial configuration devices, JTAG, or passive serial modes. The Cyclone architecture is built around a sea-of-LABs (Logic Array Blocks) structure with fine-grained interconnect, delivering predictable timing for synchronous designs.
The Cyclone architecture uses 4-input look-up tables (LUTs) grouped into Logic Elements (LEs), with each LE containing a register and carry chain logic for arithmetic operations. The 5,980 LEs of the EP1C6 make it suitable for moderate-complexity state machines, glue logic, bus bridges, and protocol conversion. On-chip memory of 92,160 bits is distributed across 20 M4K blocks, each capable of operating in single-port, simple dual-port, or true dual-port modes at up to 200 MHz.
Typical applications include industrial motor control, video processing front-ends, automotive telematics, consumer set-top box glue logic, telecommunications line cards, and low-cost DSP front-end processing. The combination of low unit price and high logic density made the Cyclone family a popular choice for prototyping and pre-production builds before ASIC migration.
When designing with this device, ensure that I/O bank VCCIO voltages match the signal-standard requirements (3.3V, 2.5V, 1.8V, or 1.5V) and that the dual-purpose configuration pins are correctly assigned. Use Quartus II (version 13.0 or earlier for full Cyclone support) for synthesis, place-and-route, and bitstream generation, and verify timing with TimeQuest.

Ứng dụng tiêu biểu
EP1C6T144LI6 phù hợp cho 6 Áp dụngs: Industrial Motor Control, Video Processing Front-End, Automotive Infotainment Glue Logic, Consumer Set-Top Box Interface Bridge, Telecommunications Line Card Glue Logic, Low-Cost DSP Pre-Processing Front-End.
Industrial Motor Control
The EP1C6T144LI6 fits industrial motor-control boards because its 5,980 LEs comfortably host PWM generation, Hall-sensor decoding, and PI/DTC control loops for a single 3-phase BLDC or stepper drive, while the 185 user I/O pins of the TQFP-144 package accommodate gate-driver interfaces, encoder inputs, and fault-monitoring signals. Two PLLs derive the PWM switching clock (typically 20-50 kHz) and the control-loop sample clock from a single 50 MHz crystal, eliminating the need for multiple oscillators on the PCB. Compared with an MCU-based design, the parallel hardware execution of the FPGA allows deterministic sub-microsecond loop times, which directly improves torque ripple and current-loop bandwidth. Industrial temperature grade (-40 to +100 °C TJ) supports factory-floor operation without derating. Companion parts include the EPC3 EPCS configuration memory and the IR2104 gate driver.
Được đề xuất
Video Processing Front-End
The EP1C6T144LI6 is well matched to video front-end tasks such as NTSC/PAL decoding, image scaling, de-interlacing, and on-screen display overlay, where 5,980 LEs and 92,160 bits of on-chip RAM are sufficient for one or two video pipelines. The M4K blocks configured as line buffers hold a full video line of pixel data, eliminating external SRAM for many designs. LVDS input support on the FPGA's differential pairs (in TQFP-144) allows direct interface to digital camera or HDMI front-end receivers without external deserializers. Quartus II reference designs and Altera application notes provide ready-to-use IP for color-space conversion and gamma correction. Companion parts include the ADV7180 video decoder and the EPCS16 configuration memory.
Được đề xuất
Automotive Infotainment Glue Logic
The EP1C6T144LI6 served as cost-effective glue logic in automotive infotainment head units, bridging I2S audio buses, CAN/LIN vehicle networks, SPI display controllers, and custom keypad matrices. With 5,980 LEs and 185 I/O pins, the FPGA absorbs protocol-translation, format conversion, and timing-management tasks that would otherwise require multiple CPLDs and bus-switch ICs, reducing BOM cost and PCB area. Two PLLs generate the audio-master clock (commonly 12.288 MHz for 48 kHz sample rates) and the display pixel clock from a single reference. Industrial temperature grade was sufficient for cabin-mounted head units in early 2000s designs. Companion parts include the TJA1050 CAN transceiver and the PCM5101A audio DAC.
Được đề xuất
Consumer Set-Top Box Interface Bridge
The EP1C6T144LI6 implements bus-format bridges in set-top boxes, converting between parallel processor buses, IDE/ATA storage interfaces, and serial transport streams such as DVB or ATSC. Its 5,980 LEs are sufficient for TS demultiplexing, PID filtering, and encryption key insertion at line rates. On-chip M4K RAM blocks provide the small packet-buffer FIFOs needed between MPEG and host-CPU interfaces, removing the need for external SRAM. Low unit cost made Cyclone the dominant choice for mid-volume consumer STB designs from 2003-2008. Companion parts include the M29W320DB flash memory and the LNBH23 LNB supply controller.
Được đề xuất
Telecommunications Line Card Glue Logic
The EP1C6T144LI6 acts as timing-and-control glue logic on telecom line cards, providing TDM bus formatting, framing, alarm-collection, and clock-distribution functions for 4-8 E1/T1 or 1-2 E3/DS3 ports. Two PLLs derive multiple clock rates (2.048 MHz E1, 8.192 MHz, 44.736 MHz DS3) from a single board reference oscillator with sub-ppm jitter. LVTTL/LVCMOS I/O standards and high pin count of the TQFP-144 package accommodate backplane interface needs. Quartus II timing closure with TimeQuest analysis supports the deterministic sub-microsecond framing and slip-buffer requirements of telecom equipment. Companion parts include the DS21348 LIU and the IDT72V36100 FIFO.
Được đề xuất
Low-Cost DSP Pre-Processing Front-End
The EP1C6T144LI6 implements the FPGA co-processor pattern widely used in mid-2000s DSP systems, off-loading FIR filters, FFT pre-processing, and data-rate conversion from a host DSP such as the TI TMS320C6000 series. With 5,980 LEs, the Cyclone can host a 32-tap FIR at 100 MHz sample rate, or a 256-point radix-2 FFT pipeline, while the 92,160 bits of M4K memory hold coefficient and twiddle tables without external ROM. The dual-port RAM mode of M4K blocks enables simultaneous coefficient read and data write operations required for streaming DSP. Quartus II MegaWizard plug-ins (now Platform Designer) generate ready-to-use FIR and FFT IP. Companion parts include the TMS320C6713 DSP and the AD9244 ADC.

Ghi chú thiết kế
Estimated: total power consumption for the EP1C6T144LI6 typical application is approximately 0.5-1.5 W depending on utilization and toggle rate. Use the Altera PowerPlay Early Power Estimator (EPE) spreadsheet with assumed parameters (LEs used: ~70%, RAM blocks: ~50%, toggle rate: 12.5%, clock frequency: 100 MHz) to refine the budget. Decouple VCCINT (1.5 V) with one 100 µF bulk + four 0.1 µF ceramic capacitors placed adjacent to package power pins (141, plus distributed across the die area) to limit switching-noise ripple below 50 mV peak-to-peak.
Do not omit pull-up resistors on the open-drain configuration pins CONF_DONE (pin 37) and nSTATUS (pin 38); both require 10 kΩ pull-ups to VCCIO of the bank containing the configuration pins. Failure to pull these up causes configuration failure on power-up with the typical Active Serial (AS) or Passive Serial (PS) configuration schemes. Also verify that dual-purpose configuration pins (DATA0, DCLK) are assigned correctly in the Quartus II pin planner so that they revert to user I/O when configuration completes.
The TQFP-144 package of the EP1C6T144LI6 requires a 4-layer PCB minimum, with one continuous ground plane beneath the package and a VCCINT island on the top layer for direct capacitor attachment. Trace impedance for high-speed I/O (such as LVDS inputs or memory interfaces) should be controlled to 50 Ω single-ended or 100 Ω differential. Maintain 3W spacing between high-speed signals (clocks, DCLK, DATA[7:0] in PS mode) and adjacent user I/O traces to minimize crosstalk; Altera application note AN224 provides detailed Cyclone layout guidelines.
