EP3C5E144C8N Ringkasan

The Intel (formerly Altera) EP3C5E144C8N is a low-power, low-cost Cyclone III Field-Programmable Gate Array (FPGA) built on a 65 nm process, offering 5,136 logic elements, 423,936 bits of embedded memory, and 23 embedded 18x18 multipliers in a 144-pin LQFP exposed-pad package. It operates from a 1.15 V to 1.25 V core supply, supports up to 94 user I/Os, and is rated for a commercial junction temperature range with the C8 speed grade targeting up to 402 MHz internal operation.

What is a Cyclone III FPGA? An FPGA (Field-Programmable Gate Array) is a semiconductor device containing programmable logic blocks, interconnect, and I/O cells that engineers can configure after manufacture to implement custom digital circuits. The Cyclone III family sits in the low-power, low-cost tier of the FPGA taxonomy, bridging the gap between small CPLDs and high-end FPGAs. Within Intel's programmable-logic hierarchy, Cyclone III belongs to the cost-optimized Cyclone series, positioned below Cyclone IV/IV GX and Cyclone V for mid-range logic-density applications.

Key features of the EP3C5E144C8N include 5,136 vertically arranged logic elements (LEs), 414 Kbits of embedded RAM (M9K blocks), 23 dedicated 18x18 hardware multipliers for DSP, two general-purpose PLLs per device, and support for multiple I/O standards including LVDS, LVTTL, LVCMOS, SSTL, and PCI. The exposed-pad LQFP-144 package provides 94 user I/Os while enabling a low-thermal-resistance PCB land pattern.

Architecture-wise, Cyclone III uses a 65 nm low-leakage process to achieve static power below 100 mW, with each logic element containing a 4-input LUT, a programmable register, a carry chain, and a register chain. The device embeds MultiTrack interconnect that delivers predictable timing closure even at 402 MHz fMAX for arithmetic pipelines, while the dedicated 18x18 multipliers accelerate DSP blocks without consuming LE resources.

Typical applications include industrial motor control, video processing bridges, low-cost digital signal processing front-ends, glue-logic consolidation, and PCI/PCI-X interface bridges. Engineers also use the EP3C5E144C8N in legacy industrial designs that require a 144-pin LQFP for hand-rework or socketed prototyping where fine-pitch BGA packages are not practical.

When designing with this device, plan power sequencing so the 1.2 V VCCINT rail ramps before or simultaneously with the 2.5 V/3.3 V VCCIO rails. Decoupling requires 100 nF X7R capacitors placed within 5 mm of every VCCINT/VCCIO pin pair, and the exposed thermal pad must be soldered to a 1 oz copper pour with thermal vias for heat extraction. Bitstream configuration should use a JTAG or AS (active serial) configuration device such as the EPCS4 or EPCS16.
