EP3C5E144I7N - Cyclone III FPGA, 5K LE, 144-EQFP | Intel
MPN: EP3C5E144I7N ✓ Hoạt độngEP3C5E144I7N Tóm tắt
A Field-Programmable Gate Array (FPGA) is a semiconductor device whose digital logic is defined after manufacture by the user, belonging to the broader family of programmable logic devices (PLDs) and sitting alongside CPLDs, ASICs, and microcontrollers as the highest-density option for custom digital hardware. Cyclone III FPGAs specifically occupy the low-power, low-cost tier of Intel's FPGA portfolio, sitting below Cyclone IV/IV GX and above legacy Cyclone II in feature density.
Key features of the EP3C5E144I7N include up to 23 embedded 18×18 multipliers (suitable for DSP blocks), 4 PLLs for clock management, support for external memory interfaces including DDR/DDR2/QDRII SRAM, and a maximum internal clock frequency rating of approximately 437.5 MHz. The device supports JTAG (IEEE 1149.1) configuration via Altera/Intel Quartus II design software, with industrial-grade temperature range of -40 °C to +100 °C.
Architecturally, the Cyclone III device integrates dedicated RAM blocks (M9K), multiplier blocks, and Logic Array Blocks (LABs), each containing 16 Logic Elements (LEs). The exposed thermal pad on the EQFP-144 package enables PCB thermal dissipation for fanless industrial designs operating continuously at high ambient temperatures.
Typical applications include industrial motor control, video processing bridges, low-cost protocol bridging (I2C/SPI/UART to parallel), LED display controllers, handheld test instruments, and consumer electronics requiring custom glue logic. The 1.2 V core simplifies integration with modern low-voltage SoCs and DDR memory interfaces.
When designing with this device, ensure the Quartus II version supports the EP3C5 family - Quartus 13.0sp1 or later is recommended, with the older Quartus II Web Edition 9.1 still functional for low-utilization designs. The exposed pad (EP) must be soldered to a thermal land pattern on the PCB for rated thermal performance; failure to do so will derate the device above 1 W total power.

Handheld Test and Measurement Instrument
The EP3C5E144I7N's low 1.2 V core (under 0.75 W total power) makes it an ideal logic engine for battery-powered oscilloscopes, logic analyzers, and portable data-acquisition instruments. Its 94 user I/O pins accept multiple logic-probe inputs simultaneously, while the 4 PLLs generate the high-speed sampling clocks (up to 437.5 MHz internal). The 5,136 LEs implement protocol decoding for SPI, I2C, UART, and CAN in parallel. The exposed-pad EQFP-144 package is hand-solderable for prototype builds, simplifying small-batch manufacturing.
Được đề xuất
Custom Glue Logic for Industrial PCs
The EP3C5E144I7N replaces dozens of legacy 74-series logic packages and PAL/GAL devices on industrial PC motherboards, consolidating custom bus arbitration, address decoding, watchdog timing, and reset sequencing into a single programmable device. With 5,136 LEs and 94 user I/O pins, one Cyclone III replaces 15-20 discrete logic ICs, reducing BOM and PCB area. The industrial temperature grade and exposed-pad package support fanless industrial PCs operating in 24/7 continuous service. The 4 PLLs derive legacy clock rates from a modern 100 MHz PCIe reference.
Được đề xuất
Surveillance Camera Image Pipeline Pre-Processing
In IP camera and security camera designs, the EP3C5E144I7N serves as a pre-processing stage that performs Bayer demosaicing, lens distortion correction, and noise reduction before handing raw frames to a downstream SoC encoder. Its 23 embedded 18x18 multipliers accelerate the multiply-accumulate operations of fixed-point image filters, while 423,936 bits of embedded RAM buffer 2-3 full HD lines at a time. The 94 user I/O pins interface directly with CMOS image sensors (HiSPi/MIPI) via LVDS or sub-LVDS, plus parallel RGB output to the encoder. The industrial temperature grade supports outdoor IP66 enclosures.

Ghi chú thiết kế
The EP3C5E144I7N ships in an EQFP-144 package with an exposed thermal pad (pin 144, the underside of the package) that must be soldered to a PCB thermal land pattern. Without proper soldering to at least 9 thermal vias to an internal ground plane, junction-to-ambient thermal resistance (theta_JA) increases significantly, derating the device above approximately 0.5 W total power dissipation. For designs operating continuously at full logic utilization (~0.75 W), provision at least 1 square inch of 2 oz copper on the top layer connected to the EP.
The Cyclone III EP3C5E144I7N requires four separate supply rails: VCCINT (1.2 V core), VCCIO (per-bank, 1.2-3.3 V depending on I/O standard), VCCA (1.2 V PLL analog), and VCCD_PLL (1.2 V PLL digital). Decouple each VCCINT pin with a 0.1 µF ceramic cap placed within 100 mils of the pin, and bulk-decouple each VCCIO bank with one 4.7 µF ceramic. PLL supplies (VCCA, VCCD_PLL) must be filtered with ferrite beads and isolated from digital noise - sharing the VCCINT plane with PLLs is a common cause of PLL jitter problems.
When designing with the EQFP-144 package, follow Intel/Altera Cyclone III package guidelines: keep all 144 signal traces on top-layer escape routing with via-in-pad only if your fab supports it, and use the 0.4 mm pitch lead spacing to calculate minimum trace width (typically 0.15 mm / 6 mil). Differential pairs (LVDS) should be length-matched within 100 mil. Place the JTAG chain (TCK, TMS, TDI, TDO) on dedicated layers or route them as a group, and ensure 10 kohm pull-ups on nCONFIG and MSEL[3:0] configuration mode pins.
Common mistakes include: (1) using Quartus II versions later than 13.0sp1 without installing the Cyclone III legacy device support, leading to silent compile failures; (2) forgetting to enable the JTAG IDCODE check during multi-device configuration chains, causing the wrong bitstream to load; (3) omitting the AS configuration flash (EPCS4/EPCS16) reset pull-up, leaving the FPGA in undefined configuration state on power-up. Always verify the configuration scheme in the Quartus II Device & Pin Options before generating the programming file.
