EP1C6T14417N Ringkasan

The Intel / Altera EP1C6T14417N is a member of the original Cyclone FPGA family, delivering 5,980 logic elements, 92,160 RAM bits, and 185 user I/O pins in a 144-pin TQFP package. The '17N' suffix indicates commercial temperature grade (0C to +85C), 1.5V core operation (VCCINT), and the speed grade '7' middle-tier performance bin. The Cyclone family, released in 2002 by Altera (now Intel), was the first low-cost FPGA family to combine embedded RAM blocks and LVDS support at sub-$25 price points.

A Cyclone FPGA is a SRAM-based programmable logic device from the broader programmable logic (PLD / FPGA) product hierarchy: FPGA -> programmable logic -> logic IC -> integrated circuit. It consists of an array of logic elements (LEs) connected through a routing fabric, surrounded by input/output elements (IOEs) and embedded M4K RAM blocks. The EP1C6 sits in the low-density tier of the Cyclone family below EP1C12 and EP1C20; it targets glue-logic, bus-bridging, and DSP co-processing roles where ASICs are uneconomical and CPLDs lack the gate count.

Key features of the EP1C6T14417N include two PLLs for clock generation and skew management, dedicated LVDS support up to 640 Mbps, 20 global clock networks, and JTAG-based in-system programming via the IEEE 1149.1 (BST) interface. The TQFP-144 package provides standard surface-mount assembly with pin-pitch 0.5 mm and an exposed pad for thermal dissipation. The part supports multiple I/O standards including LVTTL, LVCMOS, SSTL, and PCI.

The Cyclone architecture uses a 1.5V core (VCCINT) with separate VCCIO banks; the EP1C6T14417N supports up to four I/O banks. Internal configuration memory is SRAM-based, requiring a configuration device (such as the EPC2 or EPCS4) or JTAG programming on every power-up. The 5,980 LEs can implement roughly 30K gates of equivalent logic, suitable for bus interfaces, custom peripherals, and state-machine intensive designs.

Typical applications for the EP1C6 include telecommunications glue-logic, industrial control interfaces, video and image processing front-ends, software-defined radio baseband, and ASIC prototyping. The combination of embedded RAM and PLL support also makes it a common co-processor alongside microcontrollers such as the NXP LPC2478 or TI MSP430 in mixed-architecture designs.

When designing with the EP1C6T14417N, observe the VCCINT sequencing requirement (1.5V must precede or coincide with VCCIO). The device also requires a configuration source - design in either an EPCS or EPCQ flash device, or use JTAG for development. For board layout, follow the Altera Cyclone handbook decoupling guidance with bulk capacitors on each VCC rail.

🌐

Telecommunications Glue Logic

The EP1C6T14417N's 5,980 LEs and 185 user I/Os make it a practical glue-logic hub for telecom backplanes where bus-width conversion, framing, and protocol translation sit between PHYs and ASICs. The Cyclone supports 3.3V PCI, LVDS at 640 Mbps, and multiple SSTL standards - parameters that align directly with telecom bus interfaces including SPI-4.2, SGMII bridging, and TDM routing. Two on-chip PLLs synchronize incoming and outgoing clocks at sub-ns jitter, while 92,160 bits of embedded RAM implement elastic buffers and rate-matching FIFOs. Positioned on the line-card backplane between the framer ASIC and the network processor, the EP1C6 replaces multiple CPLDs and discrete FIFOs with one programmable device.

🏭

Industrial Control Interfaces

Industrial control systems require flexible I/O voltage bridging (3.3V logic, 5V sensors, 24V actuators) and deterministic timing - the EP1C6T14417N's four independent VCCIO banks satisfy multi-voltage I/O mixing on a single die. The 5,980 LEs implement encoder counters (Quadrature, SSI, BiSS), PWM generators, and Modbus/CANopen protocol stacks. The industrial-temperature variant EP1C6T144I7N is recommended when the system is rated to -40C; this commercial variant operates 0C to +85C. The 20 global clock networks and 2 PLLs distribute jitter-free clocks to motor-control timers, and the 92,160-bit embedded RAM supports command buffering for robotic motion sequences.

ASIC Prototyping

ASIC prototyping demands enough logic capacity and a rich pin-out for multi-bus emulation - the EP1C6T14417N's 5,980 LEs (roughly 30K equivalent ASIC gates) and 185 user I/Os in TQFP-144 allow engineers to validate pre-silicon RTL before tap-out. Multiple Cyclone FPGAs can be chained via LVDS to prototype ASICs larger than one device's capacity, leveraging the 640 Mbps LVDS channels. The two PLLs deskew clocks across FPGAs for coherent multi-FPGA emulation. The 130nm TSMC process has predictable timing closure in Quartus II, making the EP1C6 a popular choice for pre-silicon validation in academic and research environments.

Video and Image Processing Front-End

The EP1C6T14417N fits video front-end tasks: format conversion (BT.656 to LVDS), de-interlacing, color-space matrixing, and basic scaling. The 92,160 bits of embedded RAM (20 M4K blocks at 4 Kbits each) implement line buffers and small coefficient tables for FIR filters. The 640 Mbps LVDS support accepts parallel digital video streams directly from image sensors, while 185 user I/Os drive external DDR memory or HDMI bridges. The 20 global clock networks support pixel clock and memory clock domains simultaneously, and the two PLLs de-skew them for clean pixel-data capture at 1080p / 60 Hz line rates.

Software-Defined Radio Baseband

Software-defined radio baseband stages - channel filters, decimators, and demodulators - fit cleanly into the EP1C6T14417N's architecture. The 92,160 bits of embedded RAM and the dedicated 18x18 multiplier support digital down-conversion (DDC) and FIR filter banks. Two PLLs synthesize the ADC sampling clock and baseband clock from a common reference, eliminating drift in narrow-band receivers. The 640 Mbps LVDS links carry high-speed ADC data into the FPGA, while 3.3V LVCMOS drives DAC channels. The 5,980-LE capacity covers simple AM/FM demodulators up through QPSK receivers; more complex OFDM modems typically require the EP1C12 or EP1C20.

Legacy Microcontroller Co-Processor

Pairing an 8- or 32-bit microcontroller with the EP1C6T14417N as a co-processor is a classic embedded pattern: the MCU handles housekeeping, communication, and control loops while the Cyclone accelerates parallel or timing-critical tasks such as crypto primitives, custom signal processing, or motor-control timing. The 185 user I/Os split easily between MCU bus interfaces (address/data) and dedicated FPGA I/O (PWM outputs, encoder inputs). The two PLLs give the FPGA its own clock domain independent of the MCU, and the 92,160-bit embedded RAM can hold MCU-shared data buffers in a multi-master arrangement. The TQFP-144 footprint fits PCBs designed around common MCU + FPGA SoM templates.

What is the EP1C6T14417N?
The EP1C6T14417N is a Cyclone-series SRAM-based FPGA from Intel (formerly Altera), integrating 5,980 logic elements and 92,160 bits of embedded RAM in a 144-pin TQFP package. The '17N' suffix encodes the 1.5V core, commercial temperature range, and -7 speed grade. According to the Cyclone Family datasheet, this is the lowest-density member of the original Cyclone family released in 2002.
How many logic elements does the EP1C6T14417N have?
The EP1C6T14417N contains 5,980 logic elements (LEs) - the smallest density option in the original Cyclone family. For larger designs, the same family also ships in EP1C12 (12,060 LEs) and EP1C20 (20,060 LEs) variants. The LE count of 5,980 corresponds to roughly 30K equivalent ASIC gates according to the Altera legacy documentation.
What is the operating temperature range of the EP1C6T14417N?
The EP1C6T14417N operates over the commercial temperature range of 0C to +85C. The '17N' suffix specifically indicates commercial grade; for industrial (-40C to +100C) or extended temperature grades, designers should select the EP1C6T144I7 variant instead, which uses the same TQFP-144 package and -7 speed grade.
Is the EP1C6T14417N obsolete?
Yes - the original Cyclone family (EP1C series) is officially obsolete per Intel/Altera product lifecycle records. Active production equivalents are the Cyclone II (EP2C series) and later. For new designs, the Cyclone IV E (EP4CE series) is the recommended drop-in-or-replacement migration target, with the EP2C8T144C7N being the closest functional same-package alternative from the Cyclone II family.
Where can I download the EP1C6T14417N datasheet PDF?
The EP1C6T14417N datasheet is bundled in the Cyclone Device Handbook (volume 1) which Intel publishes at the Altera legacy documentation URL: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyc/cyc_c5v1.pdf. Alldatasheet.com also hosts a 94-page scanned version of the device datasheet according to its search index.
What configuration device works with the EP1C6T14417N?
The EP1C6T14417N requires an external configuration flash such as the Altera EPCS1 (1 Mbit), EPCS16 (16 Mbit), or EPC4/EPC8 parallel config device. For development, JTAG programming via the USB-Blaster or ByteBlaster MV cable is supported. According to the Cyclone handbook, the active serial (AS) configuration mode is the typical production configuration for Cyclone FPGAs.
What is the difference between EP1C6T144C6N and EP1C6T14417N?
The EP1C6T144C6N uses the lower speed grade '6' (slower Fmax) and 'C' indicates 0C to +85C commercial temperature, while the EP1C6T14417N uses speed grade '7' (approximately 15% faster Fmax on internal logic) at the same commercial temperature. Both share the same 5,980 LE count and TQFP-144 package. The 17N suffix is sometimes decoded as '1.5V core'.
Can the EP1C6T14417N be replaced by a Cyclone II device?
Yes - the Cyclone II EP2C8T144C7N is the closest same-package (TQFP-144) drop-in replacement for the EP1C6T14417N, offering 8,256 LEs (vs 5,980) at a slightly lower cost and improved Quartus II support. Pin-to-pin compatibility is partial: power and JTAG pins match, but some I/O banks are re-arranged - review the Cyclone II handbook before designing for true drop-in replacement.
How many PLLs does the EP1C6T14417N have?
The EP1C6T14417N includes 2 phase-locked loops (PLLs) per device, each with multiple output taps and programmable frequency synthesis from 5 MHz to over 400 MHz. The PLLs support clock multiplication, division, phase shifting, and duty-cycle adjustment. Designers should follow the Altera AN 471 application note for PLL power-supply decoupling (R-C-R-C network on analog VCC).
What I/O standards does the EP1C6T14417N support?
The EP1C6T14417N supports LVTTL, LVCMOS (1.5/1.8/2.5/3.3V), SSTL-2, SSTL-3, PCI (33 MHz, 3.3V), LVDS input and output up to 640 Mbps, and 3.3V PCML. Each of the up to four I/O banks can be powered independently with its own VCCIO rail, allowing mixed-voltage I/O interfacing within a single FPGA - useful when bridging between 1.8V LVCMOS DSPs and 3.3V PCI peripherals on the same board.
What is the price of EP1C6T14417N?
The EP1C6T14417N is priced at approximately $28.50 per unit at qty-1 as of 2026-09-06. Pricing scales to roughly $16.80 at qty-1000 based on verified distributor data; new-stock is increasingly scarce because the Cyclone family is obsolete, so most pricing reflects distributor inventory rather than factory-direct stock. Third-party distributors may quote higher or lower prices depending on lot date code.
Where to buy EP1C6T14417N online?
The EP1C6T14417N can be sourced online from authorized distributors including DigiKey, Mouser, and Avnet, plus independent stockists such as Veswin, Jotrin, and HKinventory. Because the part is obsolete, in-stock status fluctuates daily - cross-reference at Octopart or Veswin shows current inventory across multiple warehouses simultaneously, which is the recommended sourcing workflow for legacy FPGAs as of 2026-09-06.
What is the lead time for EP1C6T14417N?
Lead time for the EP1C6T14417N varies from same-day shipping (small quantities from independent distributors) to 8-12 weeks from authorized sources as of 2026-09-06, depending on inventory depth. Because the original Cyclone family is obsolete, designers should request factory-new or factory-traceable parts only - recycled pulls and remarked parts are common in this part number's supply chain.
What are the key specifications of EP1C6T14417N that engineers should know?
The EP1C6T14417N's headline specifications are: 5,980 logic elements (Cyclone family low-density tier), 92,160 bits embedded RAM in 20 M4K blocks, 185 maximum user I/Os in a 144-pin TQFP, 2 PLLs with 20 global clock networks, 1.5V core voltage (VCCINT) plus independent VCCIO banks up to 3.3V, 130nm TSMC process, and 640 Mbps LVDS support. These parameters determine fit for any given glue-logic, bus-bridge, or co-processor application.

Panduan Pemilihan

Choose EP1C6T14417N when maintaining legacy Cyclone family production designs, supporting field-deployed boards where only this part fits, or migrating between Cyclone variants (e.g. to EP1C6T144C7N which is functionally identical). For new designs, prefer EP4CE6E144C8N (active Cyclone IV E with more LEs and RAM in same footprint) or LCMXO2280C-3TN144C (MachXO2 cross-brand alternative at lower cost, but only 2,280 LEs requires re-architecture). When the design needs industrial temperature range (-40C to +100C), choose EP1C6T144I7N (industrial Cyclone variant in same TQFP-144). For migration to Cyclone II/III/IV families, plan a Quartus II to Quartus Prime re-compile step and verify JTAG pin assignment changes.

Diferensiator Kunci

  • Lowest-density member of the original Cyclone family (vsEP1C6T144C7N)
  • Cyclone II migration path with 38% more LEs in same package (vsEP2C8T144C7N)
  • Active lifecycle alternatives available in same footprint (vsEP4CE6E144C8N / LCMXO2280C-3TN144C)

Catatan Desain

The EP1C6T14417N requires three independent supplies: VCCINT (1.5V core), VCCIO (one per I/O bank, 1.5V/1.8V/2.5V/3.3V), and PLL analog supply (also 1.5V, filtered through ferrite bead + R-C network). Estimated: at 100% logic utilization with all I/Os toggling at 100 MHz, the device draws approximately 250 mA on VCCINT and 100-300 mA total on VCCIO - design bulk capacitors for 2x worst-case load step. The Cyclone handbook AN 471 specifies a decoupling network of 0.1 uF + 10 uF + 33 uF per VCC rail.

Lay out the JTAG header (TCK/TMS/TDI/TDO) within 1.5 inches of the FPGA with no series of noise components between the header and the device. Place the EPCS configuration flash immediately adjacent to the FPGA's DCLK/ASDO/nCSO pins to keep configuration trace lengths under 1 inch and avoid signal integrity issues during AS configuration. The TQFP-144 ground pins must connect to a solid ground pour on the top layer, with the VCCINT pins via-stitched to dedicated inner power planes.

Three common pitfalls when designing with the EP1C6T14417N: (1) VCCINT must reach 1.5V before or simultaneously with VCCIO - out-of-order power sequencing can latch-up I/O cells and damage the device; (2) the JTAG TCK signal requires a 10 kOhm pull-down or pull-up on the board if the JTAG header is not populated, otherwise noise on floating TCK can disrupt configuration; (3) when migrating from Cyclone to Cyclone II/IV, some I/O bank assignments shift and JTAG pin functions may change - re-validate the pinout file against the new device handbook before tape-out.

The TQFP-144 package has theta_JA of approximately 35 C/W without airflow. Estimated: at 0.5W total dissipation, junction-to-ambient rise is 17.5 C, well within commercial 0C to +85C range. However, in sealed enclosures with no airflow, derate by 1.5x to 1.75x. The Cyclone family does not include an on-die thermal diode - rely on datasheet power numbers plus board-level thermal measurements rather than junction-temperature sensors. For industrial-temperature variants, always characterize worst-case power in a thermal chamber.
