EP3C5E144C7 - Cyclone III FPGA, 5K LEs, 144-LQFP | Intel

The Intel (formerly Altera) EP3C5E144C7 is a Cyclone III low-cost FPGA delivering 5,136 logic elements, 423,936 bits of embedded memory, and 94 user I/O pins in a 144-pin LQFP exposed-pad package. Manufactured on a 65nm TSMC low-power process, it operates from a 1.2V core supply and supports up to 437.5 MHz internal operation. The 'C7' speed grade and commercial temperature rating (0C to +85C) make it suitable for cost-sensitive volume production. The 144-LQFP package (EQFP-EP) with exposed thermal pad enables standard SMT assembly without BGA infrastructure. A Cyclone III FPGA is a SRAM-based programmable logic device that combines lookup tables (LEs), embedded memory blocks (M9K), embedded multipliers (18x18), and PLL-based clock management in a single die. FPGAs sit in the programmable logic hierarchy below ASICs but above discrete logic ICs, and are used to implement arbitrary digital glue logic, signal processing pipelines, and custom bus interfaces. Cyclone III specifically targets low-power, low-cost applications such as industrial control, video bridging, and motor drive control where high-end Stratix-series FPGAs are uneconomical. Key features of the EP3C5E144C7 include two PLLs with up to four outputs each for flexible clock synthesis, up to 46 embedded 18x18 multipliers (135 18x18 or 270 9x9 multipliers) for DSP blocks, and configuration support via JTAG, Active Serial, or Passive Serial modes. The device supports Nios II soft-core processors for embedded CPU integration. Embedded memory is organized as 9-Kbit blocks (M9K), totaling 46 blocks. The Cyclone III architecture separates I/O banks into four groups supporting multiple I/O standards including LVTTL, LVCMOS, SSTL, HSTL, PCI, and LVDS on selected pins. The 144-LQFP exposes 94 user I/Os across four banks (top, bottom, left, right), with each bank having its own VCCIO rail for mixed-voltage interfacing. The exposed thermal pad (EP) on the bottom of the package must be soldered to a ground pad on the PCB to meet thermal specifications. Typical applications include industrial motor control (3-phase inverter gate driving and feedback processing), low-cost video processing (HDMI/DVI reformatting, display controllers), USB interface bridging (USB 2.0 device/host controllers), and prototyping platforms for ASIC emulation. Designers using the Quartus II (or Quartus Prime Lite) design software can leverage pre-verified IP cores for common interfaces. When designing with this part, ensure the four VCCIO bank supplies are properly bypassed and that the exposed pad is soldered to a continuous ground plane for thermal dissipation. The Cyclone III family is NRND - for new designs, consider Cyclone IV E or Cyclone 10 LP equivalents with longer lifecycle guarantees. Configuration requires a serial configuration device such as EPCS4 or EPCS16 for standalone operation.

EP3C5E144C7N - Cyclone III FPGA, 5K LE, 144-LQFP | Intel / Altera

The Intel / Altera EP3C5E144C7N is a low-power Cyclone III Field Programmable Gate Array (FPGA) featuring 5,136 logic elements, 423,936 bits of embedded memory, and 94 user I/Os, housed in a 144-pin EQFP (22 x 22 mm, 0.5 mm pitch) package with exposed thermal pad. Built on a TSMC 65 nm low-power process, the 'C7' speed grade variant is specified for a 7 ns propagation delay range and is intended for industrial-grade commercial operating conditions (0C to +85C junction). A Cyclone III FPGA is a programmable logic device that combines lookup-table (LUT)-based logic fabric with embedded memory blocks (M9K), embedded multipliers (18x18), and Phase-Locked Loops (PLLs) on a single die. In the broader taxonomy, the EP3C5E144C7N belongs to the SRAM-based programmable logic family, sitting alongside Cyclone IV (next-generation low-power FPGA), Cyclone V (28 nm successor), and MAX series CPLDs. The device is non-volatile-of-configuration: bitstreams are loaded from external flash or JTAG into on-chip SRAM configuration cells, enabling unlimited re-programmability for prototyping, NPI, and field-upgradable end products. Key features include 5,136 logic elements organized into 290 logic array blocks (LABs), 46 embedded M9K memory blocks (414 Kbits), 46 embedded 18x18 multipliers, and up to 4 PLLs with 4 dedicated clock outputs. The device supports configuration schemes including Active Serial (AS), Passive Serial (PS), Fast Passive Parallel (FPP), and JTAG, and includes Cyclone III architectural primitives such as high-speed LVDS I/O, on-chip termination (OCT), and the Altera remote update IP for in-field bitstream swapping. The 144-pin EQFP package provides a thermal resistance of approximately 22 C/W with a properly soldered exposed pad. The Cyclone III architecture targets cost-sensitive high-volume applications where the previous-generation Cyclone II could not deliver sufficient logic density, DSP bandwidth, or low static power. The 65 nm process enables typical static power in the milliamp range while retaining deterministic timing closure at 200+ MHz for common logic functions and 250 MHz for DSP blocks. I/O banks support LVDS, SSTL, HSTL, LVCMOS, and PCI/PCI-X signaling standards with per-bank voltage reference supplies, enabling direct interface to DDR/DDR2 SDRAM without external level shifters. Typical applications include industrial motor control and PLC logic, video surveillance and image-processing front ends, portable medical instrumentation, low-cost software-defined radio (SDR) baseband, and consumer audio/video processing. The combination of low static power, moderate logic capacity, and a small footprint package makes the EP3C5E144C7N a strong fit for space-constrained, cost-driven designs that still need hardware-accelerated DSP or parallel sensor aggregation. When designing with this device, allocate at least an 8-layer PCB stack-up with continuous GND planes for signal integrity on LVDS pairs, and use the Quartus II / Quartus Prime design suite (13.0 or later recommended for final bitstream) with the Cyclone III device library installed. Decoupling must include 0.1 uF and 10 uF capacitors placed within 5 mm of every VCCIO/VCCINT ball pair, and the exposed thermal pad must be soldered to a 1 sq. inch copper pour to keep junction temperature within the C7 commercial rating.

EP3C5E144C8

EP3C5E144C8 - Cyclone III FPGA, 5K LE, 144-EQFP | Intel

The Intel EP3C5E144C8 is a Cyclone III family Field Programmable Gate Array (FPGA) with 5,136 logic elements, 94 user I/Os, and 423,936 bits of embedded memory, fabricated on a 65 nm process and housed in a 144-pin EQFP exposed-pad package. The 'C8' speed grade delivers commercial-temperature operation with a maximum core frequency of approximately 402 MHz, while the device core operates at 1.2 V. An FPGA (Field Programmable Gate Array) is a programmable logic device that combines configurable logic blocks (CLBs), programmable interconnect, and dedicated I/O cells on a single silicon die. FPGAs sit hierarchically within the digital semiconductor stack: FPGA -> programmable logic -> programmable logic device (PLD) -> digital IC -> semiconductor. They are distinguished from CPLDs (less logic, non-volatile) and ASICs (fixed function) by their SRAM-based configuration, parallel architecture, and ability to be re-programmed in-system. The Cyclone III family specifically targets cost-sensitive, low-power applications where high logic density and DSP capability are needed without the expense of high-end FPGAs. Key features include 5,136 logic elements in 321 LABs (Logic Array Blocks), 23 embedded 18x18 multipliers for DSP, 423,936 bits of embedded RAM (RAM bits), 4 PLLs for clock management, and 94 general-purpose I/O pins supporting LVDS, LVCMOS, SSTL, and HSTL I/O standards. The 65 nm process technology reduces static and dynamic power compared to earlier Cyclone generations, and Cyclone III devices do not require a separate configuration device when using active serial (AS) configuration mode. Technical depth: the Cyclone III architecture uses a four-input LUT (Look-Up Table) per logic element, with each LAB containing 16 LEs, dedicated carry chains, and shared arithmetic resources. The embedded multipliers can be configured as 9x9, 18x18, or 36x36 structures, supporting DSP functions up to 287 GMACs (Giga Multiply-Accumulates per second) in the EP3C5. Configuration is supported via JTAG, Active Serial (AS), Active Parallel (AP), and Passive Serial (PS) modes, with Quartus II as the primary design tool. Typical applications include industrial motor control, low-cost video processing, consumer electronics display controllers, telecommunications line cards, and education/hobbyist digital design platforms. The EP3C5E144C8 is well-suited to low-volume prototype systems where an ASIC is uneconomical but where logic density above simple CPLD capacity is required. Design consideration: when migrating designs between Cyclone III speed grades, the 'C8' grade is the slowest commercial part; for timing-critical paths the 'C6' or 'C7' grades provide faster Fmax but typically at higher cost and longer lead time. Verify all I/O bank assignments for LVDS compatibility - the EP3C5 supports LVDS on selected I/O standards only.

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.

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.

EP3C5F256C7 - Cyclone III FPGA, 5,136 LE | Altera

The Altera EP3C5F256C7 is a Cyclone III FPGA that integrates 5,136 logic elements, 423,936 RAM bits and 182 user I/O pins in a 256-ball LBGA package. Built on a 65 nm process with a 1.2 V core supply, it is rated for a listed 437.5 MHz internal clock frequency and is intended for low-cost, high-volume logic integration in commercial equipment. An FPGA, or field-programmable gate array, is a reconfigurable integrated circuit whose logic fabric, routing and I/O behavior are defined after manufacturing by a configuration bitstream. Inside an FPGA hierarchy, the EP3C5F256C7 belongs to FPGA -> programmable logic -> integrated circuit, sitting above CPLDs in density but below high-end transceiver-rich FPGAs. Designers use FPGAs when requirements change after production or when parallel, low-latency custom datapaths are more efficient than a microcontroller or ASIC. The Cyclone III family specifically targets low-power, cost-sensitive applications. Key features include 5,136 logic elements for implementing state machines, counters and datapath logic; 423,936 RAM bits for FIFO and line buffers; 182 user I/O configured to various voltage levels and I/O standards; and a 256-ball BGA enabling compact routing. The 1.2 V core and 65 nm process reduce static and dynamic power relative to older 90 nm FPGAs. The commercial C7 ordering grade balances speed and temperature for standard equipment. At the architecture level, the 65 nm fabric uses logic array blocks connected by programmable routing; embedded memory and I/O elements are fixed resources surrounding the core. Designers compile HDL with Intel/Altera Quartus II or Quartus Prime, which maps logic, performs placement and routing, and generates bitstreams stored in EPCS or EPCQ serial configuration devices. The 437.5 MHz figure from distributor data indicates the internal clock performance achievable for speed grade 7 in favorable designs; final Fmax depends on placement, fanout and I/O standard. The 256-ball LBGA package is square with ball terminals, allowing four-layer board integration. Typical applications include motor-control platforms requiring flexible I/O mapping, low-cost video processing where parallel pixel data is manipulated, industrial communication bridges, and test instruments. Its 5,136 logic elements fit compact soft processors, custom serial interfaces and real-time control.

EP3C5F256I7 - Cyclone III FPGA 5136 LE 256-BGA | Intel

Intel EP3C5F256I7 is a Cyclone III field-programmable gate array (FPGA) containing 5,136 logic elements, 423,936 RAM bits, and up to 182 user I/O pins in an industrial-temperature 256-ball FineLine BGA (FBGA-256) package. It is used in cost-sensitive applications that need reprogrammable parallel logic rather than a fixed-function ASIC or MCU. An FPGA is an integrated circuit whose digital logic can be configured by the designer after manufacturing. In the component hierarchy, an FPGA is a programmable logic device (PLD) under the broader integrated circuit category, and it differs from a microcontroller by implementing parallel hardware logic instead of sequential software instructions. The EP3C5F256I7 is part of Intel's Cyclone III family, a mid-capacity low-cost FPGA line that balances logic density, memory, I/O count, and package size for industrial and communications systems. The EP3C5F256I7 combines 5,136 logic elements with 423,936 bits of embedded RAM, 182 user I/O pins, and a 256-ball FBGA package. This capacity allows small state machines, UART/SPI bridges, FIFO buffers, image line buffers, motor-control logic, and communication protocol engines to be implemented in a single device. The industrial-temperature ordering option indicates the device is intended for extended-temperature equipment rather than consumer-only environments. The device uses a square, ball-terminated FBGA-256 package with a lead-free finish according to the verified distributor listing. The high user-I/O count exposes most internal signals to board-level interfaces, making the FPGA practical as a glue-logic, pre-processing, or interface bridging element in a larger electronic system. Because Cyclone III devices are SRAM-based FPGAs, they require an external configuration device or host controller to load the bitstream after power-up. Typical applications include industrial motor and PLC control, machine-vision image preprocessing, Ethernet and serial protocol bridging, data-acquisition front ends, and medical monitoring equipment. The 182 user I/O signals can connect to ADCs, DACs, sensors, memory buses, transceivers, and parallel LCD or LED interfaces. When designing with the EP3C5F256I7, plan for BGA fanout and adequate power decoupling, and verify that the external configuration-source choice is compatible with required boot time and update flow. Use Intel Quartus software for pin assignment validation against the target board footprint. The package and pin count are significant PCB layout constraints. This page adds practical value beyond a datasheet by combining distributor sources, same-family drop-in alternatives, estimated pricing, design guidance, and application context that helps engineers confirm the EP3C5F256I7 fits before committing to a layout.

EP3C5U256C7 - Cyclone III FPGA, 5K LE, 256-UBGA | Altera

The Intel (formerly Altera) EP3C5U256C7 is a low-power Cyclone III Field-Programmable Gate Array (FPGA) built on a 65nm low-k process, delivering 5,136 logic elements, 423,936 bits of embedded memory, and 182 maximum user I/O pins in a 256-ball Ultra FineLine BGA (UBGA) package. It operates across a commercial 0C to 85C junction temperature range with a -7 speed grade, targeting cost-sensitive, power-aware volume production. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit whose logic functionality is defined by the user after manufacturing, rather than at the fab. FPGAs sit alongside microcontrollers, microprocessors, ASICs, and CPLDs in the programmable logic hierarchy, and they are the dominant solution when time-to-market, parallelism, hardware re-programmability, or high I/O bandwidth outweigh the absolute lowest unit cost of an ASIC. The Cyclone III family from Intel/Altera occupies the low-end, low-power segment of that hierarchy, optimized for high-volume consumer, industrial, automotive, communications, and broadcast applications. The EP3C5U256C7 features 5,136 logic elements, 321 logic array blocks, 46 embedded 18x18 multipliers, 23 embedded M9K memory blocks (423,936 total RAM bits), and four general-purpose PLLs. Its 256-ball UBGA package provides 182 available user I/Os arranged in eight I/O banks supporting multiple I/O standards including LVDS, LVTTL, LVCMOS, PCI, and SSTL. The device supports Nios II embedded processor soft cores and is configured via serial or parallel flash using the active serial (AS) configuration scheme. Typical applications for the EP3C5U256C7 span consumer video processing (display controllers, video bridging, low-end set-top boxes), industrial control and machine-to-machine (M2M) gateways, automotive infotainment and driver-assist subsystems, communications line cards and bridges, broadcast video encoding, and portable/mobile systems where the low-power 65nm process and wide I/O flexibility deliver the best price/performance balance. When designing with this device, plan power sequencing carefully: the Cyclone III core and I/O banks operate from multiple supply rails (VCCINT, VCCIO per bank, VCCA, VCCD_PLL), and decoupling bulk capacitors must be placed adjacent to each power pin per the pin connection guidelines. Confirm Quartus II or Quartus Prime software support for the -7 speed grade and your target I/O standard before PCB fabrication.

EP3C5U256C7N - Cyclone III FPGA 5K LE 256-BGA | Intel / Altera

The Intel / Altera EP3C5U256C7N is a Cyclone III low-power Field Programmable Gate Array (FPGA) containing 5,136 logic elements (LEs), 423,936 bits of embedded memory, and 182 user I/Os, housed in a 256-ball FineLine BGA (UBGA) package. Built on a 60 nm TSMC low-power CMOS process, the Cyclone III family targets cost-sensitive applications that require moderate logic density, generous block memory, and flexible DSP blocks without the power budget of competing families. A Field Programmable Gate Array is a programmable integrated circuit whose logic fabric, interconnect, and I/O cells are configurable through SRAM-based configuration memory. Within the broader semiconductor taxonomy, an FPGA sits at the top of the digital logic hierarchy alongside ASICs and CPLDs, providing higher logic density than CPLDs while offering faster time-to-market and lower NRE cost than ASICs. Cyclone III specifically addresses the volume-priced, power-constrained segment between CPLDs and high-end FPGAs. Key features of the EP3C5U256C7N include 5,136 LEs, 423,936 embedded RAM bits organized into M9K blocks, up to 23 embedded 18x18 multipliers for DSP, four PLLs for clock management, and 182 maximum user I/Os. The device operates from a 1.15 V to 1.25 V core supply and supports commercial temperature grades. Cyclone III FPGAs are designed for sub-100 mW static power dissipation depending on configuration. The architecture combines Look-Up Tables (LUTs) for combinational logic, dedicated carry chains for fast arithmetic, and M9K memory blocks capable of true dual-port operation. This combination allows designers to implement both glue logic and DSP-intensive functions such as filters, FFTs, and protocol bridges on a single device. The four PLLs support clock multiplication, division, and phase shifting across the device's clock networks. Typical applications include industrial motor control, video processing and image preprocessing, automotive infotainment, consumer electronics with custom interfaces, low-cost software-defined radio, and portable instrumentation. Cyclone III FPGAs are also widely used in educational platforms and prototype ASIC emulation where fast iteration matters more than absolute performance. When designing with this part, pay close attention to the I/O bank supply voltages and the configuration scheme (AS, PS, JTAG). Cyclone III devices are configured through Quartus II or the Quartus Prime toolchain, and the BSDL files are generated automatically. The 256-ball UBGA package requires careful PCB layout with controlled-impedance traces and a sufficient ground/power via array under the BGA. This page synthesizes distributor pricing, drop-in same-package Cyclone III alternatives, practical design notes, and a parametric comparison table that goes beyond the manufacturer datasheet summary, giving engineers a single source for evaluation and sourcing decisions.
