EP3C10E144I7N نظرة عامة

The Intel (formerly Altera) EP3C10E144I7N is a low-power, low-cost Cyclone® III Field Programmable Gate Array (FPGA) built on a 65nm CMOS process, offering 10,320 logic elements, 423,936 bits of embedded memory, and 66 (9x9) multipliers, housed in a 144-pin LQFP package with exposed thermal pad.

Key features include 94 user I/O pins, two general-purpose PLLs, 23 embedded 18x18 multipliers, 46 M9K memory blocks, and a core supply of 1.2V with I/O supply supporting LVDS, LVCMOS, SSTL, and HSTL I/O standards. The device operates at a maximum internal clock frequency of approximately 472.5 MHz, supported by Cyclone III's low static and dynamic power architecture.

The Cyclone III family (EP3C family) is a programmable logic device sitting in the broader hierarchy of FPGA -> programmable logic -> semiconductor. FPGAs contain configurable logic blocks (CLBs/LEs), programmable interconnect, embedded memory, and dedicated hardware such as PLLs and multipliers, enabling parallel hardware acceleration, custom peripheral interfacing, and glue-logic integration. The Cyclone III family in particular targets cost-sensitive, power-sensitive applications where higher-end Stratix devices are over-specified.

This specific variant EP3C10E144I7N is the 144-LQFP / EQFP-144 commercial-grade option, with the 'I7' suffix indicating the industrial temperature range (-40°C to +100°C junction), and the 'N' suffix denoting lead-free / RoHS-compliant packaging. The 144-LQFP footprint enables low-cost PCB assembly using standard SMT lines, making it attractive for industrial control, motor drive, video processing, and consumer designs.

Typical applications include industrial motor control (using the embedded multipliers for FOC algorithms), video surveillance image processing, automotive infotainment prototyping, low-cost software-defined radio front-ends, and display controllers for industrial HMMIs. The device's embedded M9K memory blocks efficiently buffer video line storage, while the PLLs synthesize the pixel clock from an external reference.

When designing with this FPGA, pay attention to the bank-by-bank I/O supply voltage configuration, use the Quartus II (or newer Quartus Prime) toolchain for synthesis, place decoupling capacitors near each VCCINT/VCCIO supply pin, and follow the exposed-pad PCB layout guideline for the EPAD thermal dissipation pad. Consider migrating to the Cyclone IV E (EP4CE10) family for new designs because Cyclone III is approaching end-of-life.

This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes that complement - but do not duplicate - the manufacturer datasheet.

التطبيقات النموذجية

EP3C10E144I7N مناسب لـ 6 التطبيقs: Industrial Motor Control (FOC), Video Surveillance Image Processing, Low-Cost Software-Defined Radio (SDR) Front-End, Industrial HMI / Display Controller, Automotive Infotainment Prototyping, Portable Test & Measurement Instrumentation.

🏭

Industrial Motor Control (FOC)

The EP3C10E144I7N fits field-oriented control (FOC) motor drives thanks to its 23 embedded 18×18 multipliers and 472.5 MHz maximum clock, which can sustain a 50 kHz PWM update plus 10 kHz current-control loop per axis. Its industrial -40°C to +100°C temperature grade matches the operating envelope of factory-floor drives and traction inverters. The 94 user I/Os are sufficient to drive three-phase PWM, encoder QEP inputs, Hall sensors, and a CAN/RS-485 control interface simultaneously. Designers pair it with the ADC and gate-driver companion MPNs below to build a complete sensorless or sensored PMSM controller on a single low-cost board.

🎥

Video Surveillance Image Processing

The EP3C10E144I7N's 423,936 bits of embedded RAM (46 M9K blocks) comfortably buffers one or two video lines at typical 720p / 1080p widths, enabling real-time Sobel, Canny, or motion-detection preprocessing on D1/720p streams. The two PLLs synthesize the pixel clock from a 27 MHz oscillator and generate separate clocks for the image sensor, SDRAM controller, and Ethernet MAC. The 23 embedded multipliers accelerate convolution kernels for edge detection without burning external DSPs. Compared with an MCU-based approach, the FPGA delivers 10× higher throughput per dollar and the 144-LQFP exposed-pad package keeps PCB cost low for volume IP-camera manufacturing.

🌐

Low-Cost Software-Defined Radio (SDR) Front-End

The EP3C10E144I7N is a popular SDR platform thanks to 10K logic elements and 23 DSP multipliers that can run digital down-conversion (DDC), finite-impulse-response filtering, and quadrature demodulation at baseband rates up to 50 MSPS. The 94 LVDS-capable user I/Os comfortably interface a 12- or 14-bit ADC at full sample rate. Industrial temperature grade and 1.2 V low core voltage make it a good fit for rugged portable SDR front-ends. Compared with a discrete DSP + MCU approach, the FPGA reduces BOM cost and lets experimenters iterate the demodulation chain in VHDL/Verilog in minutes.

Industrial HMI / Display Controller

The EP3C10E144I7N drives TFT-LCD panels up to 800×480 at 60 Hz comfortably because the embedded multipliers accelerate font rasterization and 2D bitmap composition in real time. The 94 user I/Os support a parallel 16/18/24-bit RGB interface plus a 4-wire resistive touch controller and an SPI/I2C host link to a host MCU. The industrial -40°C to +100°C operating envelope suits factory HMI panels, marine instrument displays, and outdoor kiosks. Designers using this part avoid the need for a dedicated graphics controller IC and can customize the UI without an external display driver firmware dependency.

🚗

Automotive Infotainment Prototyping

The EP3C10E144I7N is widely used in automotive infotainment prototype and reference designs because of its industrial-grade temperature range, plentiful LVDS-capable I/Os for LCD panels, and Altera/Intel reference designs for CAN, MOST, and Ethernet AVB. The 10,320 LEs are sufficient to implement a media player state machine, audio mixing, and CAN gateway in a single device. Designers use the Quartus II IP catalog for CAN, I2S, and Ethernet MAC cores. For production-bound automotive designs, migrate to the AEC-Q100-qualified MAX10 or Cyclone V family, since the EP3C10E144I7N is not formally automotive-qualified despite its industrial temperature grade.

Portable Test & Measurement Instrumentation

The EP3C10E144I7N's 472.5 MHz internal clock plus 23 embedded multipliers suit low-cost benchtop instruments such as protocol analyzers, logic analyzers with up to 94 channels, or arbitrary waveform generators with on-the-fly DDS synthesis. The 46 M9K memory blocks store deep capture buffers without external SRAM, simplifying the BOM. The 144-LQFP exposed-pad package supports standard SMT assembly and the device is in stock at multiple distributors as of 2026-09-09 despite NRND status. The industrial temperature range lets the same hardware serve factory test racks and outdoor field service kits.

Both share identical silicon, 144-LQFP exposed-pad pinout, 10,320 LEs, and industrial temperature grade, so they are drop-in compatible.

Can EP3C10E144C8N replace EP3C10E144I7N?

Yes, the EP3C10E144C8N (commercial temperature grade) is functionally identical and pin-to-pin compatible with the EP3C10E144I7N (industrial temperature grade) on the same 144-LQFP exposed-pad footprint, differing only in the upper temperature limit (85°C commercial vs 100°C industrial junction). For drop-in replacement of an industrial-grade design you should keep EP3C10E144I7N or upgrade to I7N rather than downgrade to C8N.

What is the best drop-in replacement for EP3C10E144I7N?

The best drop-in replacement for the EP3C10E144I7N in the same 144-LQFP exposed-pad footprint is the EP3C10E144I7 (industrial grade, SnPb or non-'N' finish) or the EP3C10E144C7N (commercial grade, lead-free), both featuring identical 10,320 LEs, 94 user I/Os, and pinout. For new designs we recommend the Cyclone IV E (EP4CE10F100C8N) successor family, although it requires a different package (100-FBGA).

Where to download EP3C10E144I7N datasheet PDF?

The official EP3C10E144I7N datasheet can be downloaded as a PDF from the Intel Cyclone III Device Handbook page at intel.com/content/www/us/en/programmable/documentation/lit-cyc3.html. The Datasheets360 page also provides a direct PDF mirror at datasheets360.com/part/detail/ep3c10e144i7n/-6509668253741636723. The Cyclone III Family datasheet (document number CYIII51001, formerly Cyclone III Device Handbook) covers the EP3C10E144I7N in chapter 1 and the I/O, PLL, and memory chapters.

Where to find EP3C10E144I7N pinout?

The EP3C10E144I7N pinout is documented in the Cyclone III Device Handbook Pin Information chapter, specifically the 144-pin EQFP (E144) variant section. Intel's Pin-Out Files for Quartus II also provide an Excel/PDF pinout reference. For visual reference, the package_svg_key on this page renders the LQFP-144 exposed-pad top-view pin diagram.

What are the key specifications of EP3C10E144I7N that engineers should know?

Engineers designing with the EP3C10E144I7N should remember four headline numbers: 10,320 logic elements, 423,936 bits of embedded RAM (46 M9K blocks), 94 user I/O pins, and 23 embedded 18×18 multipliers, all packaged in a 144-LQFP exposed-pad form factor operating from a 1.2 V core supply with 472.5 MHz maximum internal frequency. Industrial temperature grade ('I7') spans -40°C to +100°C junction, and the 'N' suffix confirms lead-free RoHS-compliant assembly.

دليل الاختيار

Choose the EP3C10E144I7N when you need a low-cost, low-power 10K-LE FPGA in a 144-LQFP exposed-pad package with industrial temperature grade (-40°C to +100°C) and lead-free RoHS compliance for factory-floor, outdoor, or ruggedized industrial products. Choose the EP3C10E144I7 if you need the same silicon but with non-RoHS SnPb finish (legacy designs or aerospace exception cases). Choose the EP3C10E144C7N or EP3C10E144C8N for cost-sensitive consumer or commercial-grade products that do not need the full industrial temperature range. For new designs starting in 2026, we recommend migrating to the pin-compatible Cyclone IV E (EP4CE10E22I7N) on the same 144-EQFP footprint because Cyclone III is NRND; verify Quartus project migration for any bank-voltages or PLL configuration differences.

ملاحظات التصميم

Estimated: at 50% logic utilization, the EP3C10E144I7N core draws approximately 200-400 mA from the 1.2V VCCINT rail. Provide at least 2A of headroom on the 1.2V regulator. Each VCCIO bank (1 through 12 on the EQFP-144) can draw up to 200 mA depending on switching activity; decouple every VCCIO pin with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, plus a bulk 10 µF tantalum per bank. The VCCA_PLL pins require dedicated 2.5V filtered from the 2.5V rail through a ferrite bead to minimize PLL jitter.

Solder the EPAD (exposed thermal pad, pin 145) directly to a 5 mm × 5 mm copper pad on the top layer, stitching it with 0.3 mm thermal vias on a 1 mm pitch to an inner ground plane. This is the primary heat-dissipation path; failure to solder the EPAD will cause thermal runaway in industrial temperature operation. Place configuration mode jumpers (MSEL[3:0]) within 25 mm of the MSEL pins to ensure clean mode selection, and route JTAG (TCK/TMS/TDI/TDO) as a daisy-chain with 33 Ω series termination if the chain length exceeds 75 mm.

Do not mix VCCIO voltages on adjacent banks without verifying the bank-to-bank isolation rules in the Cyclone III datasheet. Conf_Done (pin 143) must be pulled high with a 1 kΩ resistor and the configuration flash (EPCS16 or compatible) must match the chosen compression mode. When migrating from Cyclone III to Cyclone IV E (EP4CE10E22I7N), review the Quartus project migration guide because the I/O bank count, PLL count, and configuration scheme differ even though the pinout is pin-compatible on the 144-EQFP footprint.
