EP1C3T100C7N - Cyclone I FPGA, 2,910 LEs, 100-TQFP | Intel
The Intel EP1C3T100C7N is a member of the Cyclone I family of low-cost FPGAs, featuring 2,910 logic elements, 13 M4K RAM blocks (58,896 RAM bits), and one PLL, housed in a 100-pin TQFP package with 65 user I/O pins. Built on a 0.13 µm SRAM process, this device operates from a 1.5 V core supply with a commercial 0 °C to +85 °C junction temperature range and a speed grade of -7. A field-programmable gate array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs) connected via programmable interconnect. FPGAs sit in the programmable-logic hierarchy between simple PLDs and ASICs: they offer higher logic density and richer I/O than CPLDs, while remaining far cheaper and faster to prototype than full-custom ASICs. The Cyclone I family targets cost-sensitive, low-to-mid-volume designs where an MCU is too rigid and an ASIC is uneconomical. Key features of the EP1C3T100C7N include 2,910 logic elements, 58,896 bits of embedded RAM, 1 phase-locked loop for clock management, and support for LVDS, LVTTL, LVCMOS, SSTL-2, and SSTL-3 I/O standards. The 100-pin TQFP package is a thin, plastic surface-mount format with a 0.5 mm lead pitch, well-suited to hand-prototyping, low-speed production runs, and educational platforms where fine-pitch BGA handling is impractical. The architecture pairs four-input look-up tables (LUTs) with embedded memory, allowing each LE to be configured as either combinational logic or a small shift register. The single PLL supports clock multiplication, division, and phase shift, enabling reliable timing closure on designs up to roughly 100 MHz system clock. The device is SRAM-based, so configuration must be reloaded at every power-up from a serial configuration flash such as the EPCS1 or EPCS4. Typical applications for the EP1C3T100C7N include industrial control glue logic, legacy MRO replacement of obsolete ASICs, education and training boards, low-volume I/O expansion bridges, and protocol conversion such as UART-to-SPI or parallel-to-LVDS. The 100-TQFP package makes it a popular choice on dev kits and university lab cards where through-hole-friendly QFP footprints simplify rework. When designing with this part, note that the Cyclone I family is mature: Intel recommends migrating to Cyclone IV or Cyclone V for new designs, but the EP1C3T100C7N remains widely available in the distribution channel for sustaining legacy products. Always load the configuration bitstream from an external serial flash at every power-up; the FPGA has no built-in non-volatile memory. This page synthesizes distributor pricing, drop-in Cyclone I alternatives, and practical design notes - including JTAG chain and configuration flash guidance - that go beyond the datasheet bullet list to support engineers sustaining legacy Cyclone I designs.
EP1C3T100C8 - Cyclone FPGA 2,910 LEs TQFP-100 | Intel | EOL
The Intel (formerly Altera) EP1C3T100C8 is a member of the original Cyclone FPGA family built on a 1.5 V core, 0.13 µm SRAM process, delivering 2,910 logic elements and 59,904 RAM bits in a 100-pin TQFP package with 65 user I/O pins. The device runs at an internal speed grade of -8 (commercial, slowest of the Cyclone I speed grades), and supports LVTTL, LVCMOS, SSTL-2, SSTL-3, LVDS, and RSDS I/O standards for flexible digital interfacing. A field-programmable gate array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable routing, and dedicated hard IP such as block RAM, PLLs, and I/O serdes. FPGAs occupy the middle ground between fixed-function ASICs and software-driven microcontrollers: the silicon is generic, but designers define every flip-flop, LUT, and interconnect at compile time using HDL bitstreams. Within the broader taxonomy, the EP1C3T100C8 sits at FPGA & CPLD > programmable logic > semiconductor IC. Key specifications include 13 M4K RAM blocks (4 Kbits each, plus 512 parity bits) totaling 59,904 memory bits, one general-purpose PLL for clock synthesis and phase shifting, embedded multipliers are not present on EP1C3 devices, and 65 LVDS-pair-capable or 3.3 V-tolerant user I/Os. Configuration is supported via active serial (AS), passive serial (PS), and JTAG modes, allowing the device to boot from low-cost EPCS configuration memories or be programmed in-circuit through the JTAG header. Architecture-wise, the Cyclone I family uses 4-input look-up tables (LUT4) per logic element with a dedicated register and carry chain for arithmetic, plus per-LAB control signals. The 0.13 µm process with copper interconnect minimizes dynamic power, while the 1.5 V core VCCINT keeps static leakage low for cost-sensitive, high-volume applications. Die size and routing density are tuned for designs in the 2K-3K LE range such as glue logic, I/O expansion, custom peripherals, and protocol bridges. Typical applications include industrial control glue logic, low-cost I/O expansion and bridging (UART/SPI/I2C to parallel), legacy peripheral replacement, motor-control co-processors, educational and prototyping boards, video/display formatting front-ends, and consumer-electronics glue functions where a small, deterministic logic device replaces discrete 74-series logic. The EP1C3T100C8 is also widely used as a firmware-controlled test fixture controller in production lines. Designers should note that this device is EOL with last-time-buy status per Intel PDN1810; new designs are directed to Cyclone IV, Cyclone V, or Cyclone 10 families. For existing production, ensure the 1.5 V core is generated by a low-noise LDO and that JTAG chain integrity is verified before in-system programming. I/O bank VCCIO must be matched to the driven/receiving logic level (1.5 V, 1.8 V, 2.5 V, or 3.3 V) to prevent bus contention and long-term reliability issues. This page synthesizes distributor pricing, parametric alternatives from the same Cyclone I family, and practical EOL-avoidance guidance not consolidated on any single manufacturer or distributor page.
EP1C3T100C8N - Cyclone FPGA, 2910 LEs, 65 I/O, TQFP-100 | Intel
The Intel (formerly Altera) EP1C3T100C8N is a low-cost Cyclone FPGA from the first-generation Cyclone family, delivering 2,910 logic elements, 59,904 RAM bits, and 65 user I/Os in a 100-pin TQFP package. Manufactured on a 130-nm CMOS process, the device operates from a 1.425 V to 1.575 V core supply and supports up to 275 MHz internal operation with embedded PLL clock management. What is a Cyclone FPGA? The Cyclone family is Intel FPGA's low-cost, high-volume programmable logic series, positioned below the Stratix high-performance family in the FPGA hierarchy: FPGA -> SRAM-based programmable logic -> programmable logic device (PLD) -> digital logic IC. Cyclone parts target glue-logic, bus bridging, and DSP pre/post-processing in cost-sensitive designs where the high-end Stratix I/O bandwidth and transceivers are unnecessary. The 'N' suffix indicates lead-free, RoHS-compliant packaging. Key features include 2,910 logic elements organized into 291 logic array blocks (LABs), 13 embedded 4-Kbit M4K RAM blocks totaling ~60 Kbits, one PLL per device with up to four output taps, support for LVDS, LVTTL, LVCMOS, SSTL, and PCI I/O standards, and in-system programmability through the passive serial (PS), fast passive parallel (FPP), or JTAG configuration interfaces. The TQFP-100 footprint simplifies PCB layout for low-density designs. Architecturally, the EP1C3T100C8N uses a 4-input look-up table (LUT) based logic element with embedded carry chains for arithmetic and dedicated M4K memory blocks. The single PLL provides clock multiplication, division, and phase shift for up to three or four output clocks, sufficient for basic DDR memory interfaces and standard video/serializer timing. Typical applications include low-cost video processing, industrial control logic, consumer electronics glue logic, education and prototyping platforms, and serial protocol bridging (UART, SPI, I2C). The part is widely used in legacy designs that pre-date Cyclone II/III/IV migration; many production designs still rely on the EP1C3 due to its low unit cost and long-term Intel supply commitment. Design consideration: The EP1C3 uses a 1.5 V core and requires a separate configuration memory or download cable for in-system programming. Plan for the 1.5 V regulator (e.g., a small LDO) and a JTAG header on the PCB. Signal integrity at 100+ MHz requires impedance-controlled traces on the LVDS pairs.

EP1C3T100CB - Cyclone FPGA 2,910 LEs, 100-TQFP | Altera
The Altera (Intel) EP1C3T100CB is a member of the first-generation Cyclone FPGA family fabricated on a 0.13 µm SRAM process, delivering 2,910 logic elements in a 100-pin TQFP package. It integrates 59,904 bits of embedded RAM and provides up to 65 user I/O pins, targeting cost-sensitive applications where PLD-level logic density is required without the cost of high-end FPGAs. A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable routing, and dedicated I/O cells that can be re-programmed in-system to implement arbitrary digital logic. FPGAs sit at the top of the programmable logic hierarchy alongside CPLDs, and are widely used as prototyping vehicles, glue logic, DSP accelerators, and pre-silicon verification platforms. The Cyclone family occupies the low-cost end of that hierarchy, optimized for ASIC replacement in volume production. Key features of the EP1C3T100CB include 2,910 logic elements, 13 embedded 4-Kbit M4K RAM blocks (totalling 59,904 RAM bits), one PLL for clock management, and a flexible I/O structure supporting LVTTL, LVCMOS, SSTL-2, and SSTL-3 standards. Configuration is loaded through an industry-standard passive-serial, active-serial, or JTAG interface, enabling fast in-system programming. The 100-pin TQFP (1.0 mm pitch, 14 × 14 mm body) provides a 65-pin user I/O count after subtracting JTAG, configuration, power, and ground pins. The architecture is based on a four-input look-up table (LUT) fabric with embedded multiplier-free DSP-style logic and dedicated carry chains for arithmetic. Embedded RAM blocks can be configured as simple dual-port, true dual-port, or FIFO memory, supporting buffer and small-packet processing tasks. The Cyclone series pioneered Altera's low-cost FPGA positioning that later evolved into the Cyclone II, III, IV, and V families on finer process nodes. Typical applications include industrial control logic, low-density glue logic, communications protocol bridging, consumer electronics display controllers, and pre-silicon ASIC prototyping. The 100-TQFP package makes it suitable for through-hole-friendly prototyping boards and low-volume production assemblies that do not require BGA-level integration. When designing with this part, note that it is in production but classified as a mature-product line; new designs should compare it against Cyclone II, III, or Cyclone IV equivalents for long-term availability. Configuration data must be loaded at every power-up from an external flash memory or download cable.

The Altera (Intel Programmable Solutions Group) EP1C3T100CN8 is a member of the original Cyclone FPGA family, delivering 2,910 logic elements in a 100-pin TQFP package with up to 65 user I/O pins and 59,904 RAM bits. Operating from a 1.5 V core supply, the device is built on a 0.13 µm SRAM-based FPGA fabric and is offered in a commercial 0 °C to 85 °C temperature grade with -8 speed bin performance. What is an FPGA? An FPGA (Field-Programmable Gate Array) is a semiconductor device containing programmable logic blocks, configurable interconnect, and programmable I/O cells that engineers can configure after manufacturing to implement custom digital circuits. FPGAs occupy the tier between CPLDs (smaller, non-volatile) and ASICs (custom, high-NRE), making them ideal for prototyping, low-volume production, and applications requiring hardware-level parallelism. The Altera Cyclone family sits in the low-cost, high-volume segment, optimized for price-sensitive designs. Key features of the EP1C3T100CN8 include two PLLs for clock management, dedicated 18×18 multipliers (originally marketed under the DSP block branding), and support for LVTTL, LVCMOS, SSTL-2, and SSTL-3 I/O standards. The device supports configuration via passive serial (PS), JTAG, and Altera-specific configuration schemes, and integrates Altera's Quartus II design suite for synthesis, place-and-route, and timing closure. Technically, the Cyclone architecture pairs 4-input look-up-tables (LUTs) with embedded memory blocks (M4K blocks) and distributed multiplier resources. The 100-pin TQFP package provides moderate I/O count with surface-mount manufacturability but limits total pin count compared to BGA-packaged Cyclone variants, so it is typically chosen for I/O-light glue logic, control planes, and industrial interface bridging. Typical applications include industrial control and bridging, low-cost video processing front-ends, peripheral expansion in embedded systems, glue logic replacing discrete MSI parts, and education/hobby platforms. Designers choose the EP1C3T100CN8 over larger Cyclone devices when logic requirements fit within 3K LEs and the TQFP package simplifies assembly. Design consideration: this part is NRND/EOL per Intel PSG's Cyclone legacy notice — verify lifetime-buy windows and consider modern Cyclone IV/V/10 equivalents for new designs. Always validate timing closure at the chosen speed grade against target fMAX. This page synthesizes distributor inventory, drop-in same-package alternatives, and practical design context that goes beyond the manufacturer datasheet front matter, helping engineers source and apply the EP1C3T100CN8 quickly.

The Intel EP1C3T100I7 is a low-cost Cyclone FPGA from the Cyclone I family, integrating 2910 logic elements, 59904 bits of embedded RAM, and 65 user I/Os in a 100-pin TQFP package. Built on a 130 nm process with a 1.5 V core supply, the device supports up to 320.1 MHz internal operation and is offered in an industrial temperature grade (-40C to +100C). The EP1C3T100I7 carries the speed grade 7 designation, indicating a balance of timing margin and power consumption suitable for general-purpose logic integration. A Cyclone FPGA belongs to the field-programmable gate array (FPGA) family, a class of programmable logic devices (PLDs) that allow designers to configure digital logic, memory blocks, and I/O behavior after PCB fabrication. Within the system hierarchy, an FPGA sits between a microcontroller (fixed instruction set, software-defined behavior) and an ASIC (fully custom silicon, no post-fabrication changes). The Cyclone I family was introduced by Altera (later acquired by Intel) in 2002 as a low-cost alternative to the Stratix family, targeting consumer, industrial, and communication applications where deterministic parallel logic was preferred over software execution. Key features include 2910 logic elements distributed across 291 LABs (Logic Array Blocks), 13 embedded M4K RAM blocks totaling 59904 bits, one PLL for clock management, and 65 user I/Os. The device supports LVTTL, LVCMOS, SSTL-2, and SSTL-3 I/O standards, and is configured via a serial configuration device such as the EPC2 or EPCS family. The 100-pin TQFP package provides a 1.0 mm lead pitch suitable for standard 4-layer PCB designs with no need for microvia or HDI processes. Architecture-wise, the Cyclone I uses a 4-input look-up table (LUT) based logic fabric with embedded multiplier support for DSP operations, although the EP1C3T100I7 has a limited number of 9x9 multipliers. The device is configured from an external flash memory at power-up, after which it operates deterministically according to the loaded bitstream. The I7 industrial speed grade and -40C to +100C operating range make it suitable for factory automation, motor control, and protocol bridging in environments beyond commercial temperature ranges. Typical applications include glue logic replacement, custom interface bridging (UART to SPI, I2C to parallel), low-density video processing, industrial sensor aggregation, and education/hobby designs. The wide Quartus II tool support and abundant reference designs make it accessible for prototyping. When designing with the EP1C3T100I7, allocate configuration flash memory (EPCS1 or larger) and respect the 1.5 V core / 3.3 V I/O supply separation. Note that this part is part of an older generation; long-term availability should be confirmed before new designs. This page synthesizes distributor pricing, drop-in same-family alternatives (such as the EP1C3T100I7N and EP1C3T100C8N), and practical design considerations not collected on any single datasheet or distributor listing.
EP1C3T100I7N - Cyclone I FPGA, 2910 LE, 100-TQFP | Intel
The Intel (Altera) EP1C3T100I7N is a low-cost Cyclone® I Field Programmable Gate Array (FPGA) containing 2,910 logic elements, 59,904 RAM bits, and 65 user I/Os in a 100-pin TQFP package. Built on a 0.13 µm SRAM process, it operates with a core voltage of 1.5 V and supports industrial temperature ranges, making it a proven entry-level programmable logic device for cost-sensitive designs. A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, allowing hardware engineers to implement custom digital circuits after fabrication. FPGAs sit hierarchically between ASICs (fixed-function, high-NRE) and microcontrollers (software-defined, lower throughput), offering hardware-level parallelism with no NRE cost. Cyclone I is Intel's (formerly Altera's) first-generation low-cost FPGA family, optimized for volume production in consumer, industrial, and communications applications. Key specifications include 2,910 logic elements organized into 291 Logic Array Blocks (LABs), 13 embedded 18×18 multipliers, one PLL per device, and 59,904 bits of embedded SRAM arranged as M4K blocks. The 100-pin TQFP package exposes 65 user I/Os that support multiple I/O standards including LVTTL, LVCMOS, SSTL, and PCI, and the device supports both 3.3 V/64-bit and 66 MHz PCI standards. A single enhanced configuration block supports multiple boot modes including JTAG, Active Serial, and Passive Serial. The Cyclone I architecture employs a four-input look-up table (LUT) logic element with a dedicated carry chain for arithmetic operations and a register that can be configured as D, T, JK, or SR flip-flop. Multipliers are implemented as hard 18×18 blocks to accelerate DSP functions such as FIR filters and FFT butterflies. Embedded M4K RAM blocks each provide 4 Kbits of true dual-port memory at up to 200 MHz operation. Typical applications of the EP1C3T100I7N include consumer electronics glue logic, industrial control interfaces, low-resolution video processing, I/O expansion and bridging, and digital signal processing front-ends. The combination of small logic density, low unit cost (around $21 USD on the open market as of 2026-09-06), and a 100-pin TQFP that is hand-solderable and breadboard-friendly makes it especially well suited to prototype and legacy production designs. When designing with this device, allocate the global clock network carefully because Cyclone I has only one or two PLLs and eight global clock lines; for multi-clock designs, use regional clock resources or instantiate a clock divider in the fabric. The 100-pin TQFP exposes no high-speed transceiver (no LVDS SERDES), so high-bandwidth serial links must be implemented in soft logic. This page synthesizes distributor pricing, drop-in Cyclone I alternatives from the same Intel/Altera family, and PCB design notes not consolidated in the original Cyclone I datasheet.

The device operates from a 1.5 V core supply with PLL support for clock multiplication, and supports LVTTL, LVCMOS, SSTL-2, and SSTL-3 I/O standards, making it suitable for SDRAM and generic parallel interfaces. Industrial temperature grade (-40C to +100C) and the lead-free TQFP-100 package support both commercial and industrial end products. The Cyclone architecture uses SRAM-based configuration cells and 4-input look-up tables (LUTs). Each logic element contains one 4-input LUT, a programmable register, and a carry chain for fast arithmetic. Embedded M4K memory blocks (4 Kbits each, plus 512 parity bits) deliver true dual-port operation at up to 200 MHz, enabling on-chip buffering for FIFOs, packet headers, and DSP coefficient storage. Typical applications for the EP1C3T100I8N include video/image processing front-ends, communication protocol bridging, and industrial motor-control signal conditioning. The PLL combined with abundant I/O makes it attractive for glue logic that replaces multiple 74-series TTL parts and CPLDs on legacy boards. When designing with this device, ensure configuration data is loaded from a compatible EPC serial configuration device, and respect the 1.5 V VCCINT requirement. The 100-pin TQFP package is lead-free and supports standard SMT reflow; use JTAG (10-pin header) for in-system programming and boundary-scan test.

EP1C3T144C6 - Cyclone I FPGA, 2,910 LEs, 144-TQFP | Altera
The Altera (Intel) EP1C3T144C6 is a Cyclone I family Field-Programmable Gate Array (FPGA) housed in a 144-pin TQFP package with 104 user I/Os, built on a 1.5 V core, 0.13 µm SRAM process. It contains 2,910 logic elements arranged in 291 logic array blocks (LABs), supported by 59,904 bits of embedded RAM and a single embedded 18-bit x 18-bit multiplier block. The device is offered in the commercial -6 speed grade and is qualified for 0 °C to +85 °C operation. An FPGA (Field-Programmable Gate Array) is a reprogrammable logic device that bridges the gap between fixed-function ASICs and discrete glue logic. Architecturally, an FPGA sits within the programmable logic hierarchy as: programmable logic device (PLD) -> FPGA -> SRAM-based FPGA -> Cyclone family. The Cyclone I family specifically targets low-cost, high-volume applications such as digital signal processing bridges, custom peripheral controllers, and protocol converters, offering ASIC-like integration with the design flexibility of in-system programmability. Key features that distinguish EP1C3T144C6 include 13 M4K RAM blocks (each 4 Kbit plus parity), a configuration scheme supporting JTAG, Active Serial (AS), and Passive Serial (PS) modes with the EPC2 configuration device family, and dual-purpose clock pins that can drive up to 8 global clock networks. The PLLs are not available on the smallest Cyclone I members, and this device contains zero embedded PLLs, so all clock management is handled by global clock trees and dedicated clock pin inputs. I/O standards supported include LVTTL, LVCMOS, SSTL-2, SSTL-3, and PCI, with the TQFP-144 package providing the largest 104-I/O option in the EP1C3 density. Typical applications span digital video processing front-ends, industrial motor-control state machines, custom bus bridges (e.g., legacy-to-PCI bridging), and prototype ASIC replacement. The Cyclone I architecture is also widely used in cost-sensitive education platforms and reference designs where Quartus II design flow is already in place. The -6 speed grade is the fastest commercial speed grade in the family, suiting timing-critical glue logic. When designing with the EP1C3T144C6, ensure the 1.5 V core supply is decoupled with 0.1 µF and 10 µF capacitors placed as close to each VCCINT/VCCIO pair as the 144-TQFP pinout allows. JTAG chain integrity must be preserved during in-system programming by buffering TCK with a series resistor to suppress reflections. Designers should verify I/O bank voltage compatibility before assigning pins because the EP1C3T144 has four I/O banks, each capable of supporting a different I/O standard independently.
EP1C3T144C6N - Cyclone 2910-LE FPGA, 144-pin TQFP | Intel
The Intel EP1C3T144C6N is a Cyclone FPGA from the Cyclone I family with 2910 logic elements, 59904 total memory bits, and 104 user I/Os, packaged in a 144-pin TQFP (T144). It is built on a 130 nm process technology, runs at up to 405.2 MHz internal operation, and operates from a 1.5 V core supply. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing. FPGAs sit in the programmable logic device (PLD) hierarchy above simple PLDs and CPLDs because they contain programmable logic blocks, programmable interconnects, and configurable I/O cells. The Cyclone family specifically targets low-cost, high-volume applications where ASIC-like performance is needed without the NRE costs of an ASIC. Key features include 2910 logic elements, 59904 bits of embedded memory, 104 user I/O pins, and 13 embedded 18x18 multipliers for DSP functions. The part supports configuration via serial configuration devices or JTAG, and includes phase-locked loops for clock management. Operating temperature range spans 0C to +85C in the commercial grade (C6 speed grade) variant. The Cyclone I architecture uses a 4-input lookup table (LUT) per logic element, embedded memory blocks (M4K) configurable as RAM, ROM, or FIFO, and dedicated multiplier blocks for digital signal processing. The 130 nm process delivers low static power consumption while still supporting high toggle rates, and the TQFP-144 package provides easy prototyping with standard solder reflow processes. Typical applications include industrial control logic, consumer electronics glue logic, video processing pipelines, communications protocol bridging, and educational FPGA development platforms. Its combination of moderate logic density and low unit cost makes it well-suited for moderate-complexity glue logic and low-volume ASIC replacement designs. When designing with this device, plan for an external configuration device (EPCS) or JTAG programmer. The TQFP-144 footprint allows hand-soldering and breadboard-style prototyping on through-hole adapter boards, which is ideal for lab and educational work. For new designs, however, consider newer Cyclone IV or Cyclone V families because Cyclone I is in mature lifecycle and may carry supply constraints. This page consolidates distributor pricing, drop-in package alternatives, and design guidance not found in the manufacturer datasheet alone, helping engineers quickly evaluate the EP1C3T144C6N for both new designs and legacy board repair.

A Field Programmable Gate Array (FPGA) is a reconfigurable integrated circuit built from a matrix of programmable logic blocks (LEs), interconnect, and embedded memory that engineers can configure after manufacture to implement any digital logic function. In the power-management hierarchy, FPGAs sit alongside processors, ASICs, and ASSPs as the highest-flexibility programmable logic option, typically after the voltage regulator and clock tree in a system block diagram. The Cyclone series targets cost-sensitive, high-volume designs where ASIC NRE is not amortisable. Key features include 2,910 logic elements, 59,904 embedded RAM bits, one PLL per device, 104 user I/Os (LVTTL/LVCMOS, SSTL, LVDS capable), and support for external memory interfaces such as DDR SDRAM and QDR SRAM. The 144-LQFP package offers a 1.0 mm lead pitch and an exposed thermal pad for improved heat dissipation in surface-mount reflow profiles, enabling hand-reworkable prototypes and production volumes alike. Architecturally, the Cyclone LE combines a 4-input look-up table (LUT) with a programmable register and dedicated carry chain. Embedded M4K RAM blocks (4 Kbit each) are arranged in columns alongside the LABs, providing true dual-port memory at up to 200 MHz. Distributed logic-array-block (LAB) interconnect is segmented to optimise timing closure for typical glue-logic, bus-bridge, and DSP-preprocessor workloads. Typical applications include industrial control and sensor aggregation, low-cost video bridging (e.g., ITU-R BT.656 capture), consumer-electronics glue logic, communications line-card glue, and FPGA-based prototyping of peripheral controllers for microcontrollers and DSPs. Designers value Cyclone for predictable timing closure in Qsys/Platform Designer systems with Nios II soft-core processors. Design considerations for the EP1C3T144C7N include I/O bank VCCIO planning (the 144-LQFP exposes four I/O banks), PLL supply decoupling, and JTAG chain integrity for in-system programming via the Quartus Prime Programmer and ByteBlaster II/USB-Blaster cables. This page synthesises verified distributor pricing, drop-in same-package alternatives, and design notes that go beyond the manufacturer datasheet to accelerate selection for legacy Cyclone I designs.
EP1C3T144C8 - Cyclone FPGA, 2910 LEs, 144-LQFP | Intel / Altera
The Intel (formerly Altera) EP1C3T144C8 is a member of the first-generation Cyclone FPGA family built on a 1.5 V, 0.13 µm SRAM process, delivering 2,910 logic elements across 144 pins in a 144-LQFP surface-mount package.

A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and dedicated I/O cells that allow the device's digital function to be redefined in the field after manufacturing. Within the broader programmable logic taxonomy, an FPGA sits between a CPLD (lower density, non-volatile) and an ASIC (higher density, fixed function), and is itself a member of the larger family of programmable logic devices (PLDs). Cyclone FPGAs specifically target low-cost, high-volume applications where ASIC-like performance is needed without the NRE cost. Key features of the EP1C3T144C8 include commercial temperature grade (0 °C to +85 °C), 8 ns speed grade (-8), 0.13 µm process node with built-in DDR SDRAM support, and configuration via JTAG or Altera serial/parallel configuration schemes. The 144-LQFP (Low-profile Quad Flat Pack) package provides gull-wing leads and 1.4 mm package height for hand-solder-friendly prototyping. The Cyclone architecture uses 4-input LUTs combined with dedicated carry chains for arithmetic, and each M4K RAM block can implement true dual-port, simple dual-port, or single-port memory with parity. The single PLL supports output frequencies up to 400 MHz with coarse and fine-grained phase shifting. Together these features make the EP1C3T144C8 sufficient for glue logic, simple state machines, and basic video/imaging pipelines. Typical applications include industrial control logic, low-cost display controllers, consumer electronics glue logic, sensor pre-processing front-ends, and education/CPLD-style development platforms. The device is widely used as a bridge between a microcontroller and high-speed peripherals such as parallel ADCs or LCD panels. When designing with the EP1C3T144C8, note that it has been classified NRND/EOL by Intel - new designs should evaluate Cyclone IV E (EP4CE6E22) or Lattice ECP5 as a migration target. Configuration data must be loaded from external Flash, JTAG, or Altera EPCS serial loader on every power-up.

EP1C3T144C8GA - Cyclone FPGA, 2910 LE, 104 I/O | Altera
The Altera (Intel Programmable Solutions Group) EP1C3T144C8GA is a Cyclone field-programmable gate array (FPGA) in a 144-lead LQFP package, providing 2910 logic elements, 59,904 RAM bits and 104 user I/O pins with a 1.425 V to 1.575 V core supply. This entry was verified from distributor listings that identify the device as a Cyclone FPGA and classify it Obsolete for new designs, but stock remains available from multiple sources as of 2026-09-06. An FPGA (field-programmable gate array) is a reconfigurable integrated circuit whose logic fabric is programmed after manufacturing using an HDL bitstream, placing it in the programmable logic device branch of the integrated-circuit hierarchy. Within that hierarchy, the Cyclone family is an entry-level, cost-optimized FPGA product line intended for low- to mid-density glue logic, I/O expansion and controller tasks. The EP1C3 sits near the low end of the Cyclone range, making it useful for designs needing modest logic and I/O resources without moving to large SoC-class FPGAs. Key verified specifications include 2910 logic elements divided into 291 LABs/CLBs, 59,904 total RAM bits, 104 user I/O pins, a core supply range of 1.425 V to 1.575 V, and an operating junction temperature range of 0 °C to 85 °C. The device is supplied in a 144-pin LQFP package with surface-mount packaging in tray media, and its verified product status is Obsolete on several distributor listings. The high I/O-to-logic ratio makes this part especially suitable for pin-intensive control and interface designs. The Cyclone architecture groups logic into LABs and embeds memory blocks in the same die, allowing state machines, small FIFOs and simple processors to be implemented in a single device. Because the part is SRAM-based, it must be configured at every power-up from an external configuration source. The 104 I/O pins can support parallel buses, low-speed serial interfaces and discrete control lines, while the 1.425 V to 1.575 V core supply reflects an early low-voltage FPGA power rail. Typical uses for the EP1C3T144C8GA include industrial control I/O, protocol bridging, display glue logic, medical monitoring front-end logic, IoT edge signal conditioning, and replacement of legacy programmable logic. With 2910 logic elements, designers can fit PID controllers, quadrature decoders, UART/SPI/I2C bridges and small custom peripherals. The commercial 0 °C to 85 °C junction rating covers most indoor and industrial cabinet environments, although extended-temperature applications should use an industrial-grade variant. When designing with this FPGA, carefully decouple the 1.425 V to 1.575 V core rail and provide a dedicated configuration clock and configuration device. Verify the exact 144-pin LQFP pin mapping from the manufacturer datasheet before laying out the PCB, because the verified web data does not reproduce the full pin table. The GA suffix and ordering code should also be validated against your assembly supplier’s RoHS or lead-free requirements.

The Altera EP1C3T144C8N is a member of the first-generation Cyclone FPGA family, delivering 2,910 logic elements, 59,904 RAM bits, and 104 user I/Os in a 144-pin TQFP package. It is built on a 1.5 V core CMOS process with support for I/O standards from 1.5 V to 3.3 V, and runs at internal speeds up to 275 MHz. The integrated PLL and on-chip memory blocks make it suitable for cost-sensitive digital logic, glue logic, and bridge designs where an ASIC would be uneconomical. An FPGA (Field-Programmable Gate Array) is a programmable semiconductor that belongs to the broader hierarchy of logic ICs > programmable logic > PLD (programmable logic device) > integrated circuit > semiconductor. Unlike a fixed-function ASIC, an FPGA's logic fabric and routing are configured by the designer after manufacture via an SRAM bitstream, which makes it ideal for prototyping, low-volume production, and designs that need frequent revisions. The Cyclone family sits at the cost-optimized, low-power end of the FPGA market, sharing architectural roots with the Cyclone II/IV/10 families. Key features of the EP1C3T144C8N include 2,910 logic elements, 13 embedded M4K RAM blocks providing up to 59,904 RAM bits, two PLLs for clock management, multi-standard I/O support (LVTTL, LVCMOS, SSTL, PCI), and a dedicated configuration interface with JTAG. The device supports both passive serial (PS) and active serial (AS) configuration modes using an Altera EPCS serial configuration device, and includes on-chip pull-up resistors during configuration for reliable board bring-up. The Cyclone architecture pairs a 4-input LUT-based logic element array with embedded multiplier-less DSP-friendly carry chains and column-based memory blocks, enabling efficient implementation of state machines, FIFOs, simple DSP, and bus-bridge functions. The 144-pin TQFP (22 mm x 22 mm, 0.5 mm pitch) is a plastic surface-mount package with a copper lead frame suitable for standard reflow profiles and four-layer FR-4 PCB designs. Typical applications include industrial control logic, motor drive interfaces, low-cost video processing bridges, glue logic for SoC-based designs, and educational platforms where the Quartus II design suite and Cyclone development boards remain supported. The 104 user I/Os accommodate multiple 8/16/32-bit parallel buses plus dedicated clock and configuration pins. When designing with this part, plan I/O bank assignments carefully because the TQFP-144 package exposes only four clock-capable PLL inputs on dedicated pins; route high-speed clocks to PLL inputs first. Use Quartus II 13.0sp1 (the last officially-supported Cyclone release) for compilation, and verify timing against the 275 MHz internal clock specification.

Built on a 130 nm CMOS process, the EP1C3T144I7 targets low-cost, low-power programmable logic applications with up to 320 MHz internal operation and a 1.5 V core supply rail. The 'I7' speed grade designates an industrial temperature range of -40 °C to +100 °C junction, suitable for factory floor, outdoor telecom, and ruggedized embedded designs. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose digital logic function is defined by user configuration rather than factory masking. Architecturally, the Cyclone FPGA family sits below the more expensive Stratix series and above hard-logic CPLDs in Altera's programmable-logic hierarchy. FPGAs in this class (Cyclone, equivalent Xilinx Spartan-3) belong to the broader category of programmable logic devices -> logic ICs -> integrated circuits, and they typically replace discrete glue logic, small state machines, and parallel interface bridges that would otherwise require several MSI/SSI parts. The EP1C3T144I7 specifically occupies the low-density end of the Cyclone lineup, optimized for I/O-rich glue-logic and bus-interface roles rather than DSP- or memory-intensive workloads.

Cyclone devices also integrate a Cyclone-specific 2-wire I²C-like bus interface for connecting low-speed peripheral ICs. Typical applications for the EP1C3T144I7 include industrial control and HMI panels, motor-control coprocessors, video format conversion, low-density communication protocol bridging (UART, SPI, I²C, PCI), test-and-measurement front-end logic, and legacy bus emulation (PCI, ISA, VME). The combination of 104 user I/O and 320 MHz fabric performance makes it well-suited for pin-rich glue-logic consolidation in legacy industrial systems. Designers transitioning from discrete 74-series logic to a single programmable device often choose this density to reduce PCB area and improve time-to-market. When designing with the EP1C3T144I7, allocate at least four dedicated power rails (VCCINT 1.5 V, VCCIO bank-specific 1.5 V–3.3 V, VCCA_PLL 1.5 V, and VCC_PGM 3.3 V) with proper decoupling per the Cyclone handbook. Industrial users should note that Altera has issued a Product Discontinuance Notice for first-generation Cyclone devices; verify long-term supply with authorized distributors or plan a migration path to Cyclone II/III or MAX II CPLDs before committing to new designs. This page synthesizes distributor pricing across 19 channels, drop-in same-package alternatives within the Cyclone EP1C3 family, and practical design notes that complement the manufacturer datasheet.

Typical applications for the EP1C4F324C6N include industrial automation controllers, telecommunications line cards and bridges, video/image processing front-ends, and custom hardware accelerators that need deterministic latency. Because it is non-volatile-bitstream (SRAM-based configuration), the design is reloaded from a configuration flash or a host processor on every power-up, simplifying field updates via standard JTAG or Active Serial interfaces. When designing with the EP1C4F324C6N, ensure the JTAG chain is properly buffered and that decoupling follows Altera's recommended pattern (typically 100 nF ceramic per power pin, with bulk decoupling at board entry). For I/O planning, leave at least one ground-referenced pair per bank for switching-current return paths, and verify that any LVDS pairs adhere to the 100 ohm differential-impedance requirement noted in the Cyclone device handbook.

Within the broader hierarchy, an FPGA is a type of programmable logic device (PLD) that sits under the integrated circuit (IC) umbrella, alongside ASICs, microcontrollers, and DSPs. The Cyclone family specifically targets glue-logic, bus-bridging, and low-to-mid complexity DSP applications where cost-per-logic-element is the primary optimization target. Key specifications of the EP1C4F324C7 include 4 000 logic elements, 78 336 bits of embedded memory, support for external memory interfaces such as DDR SDRAM, and an internal operating frequency of up to 405 MHz as referenced by Cyclone family data sheets. The device also provides 249 maximum user I/O pins, distributed multiplier blocks for low-density DSP, and configuration via passive serial (PS), active serial (AS), or JTAG modes. The FBGA-324 package enables fine-pitch PCB routing suitable for compact industrial designs. Typical applications for the EP1C4F324C7 span industrial control and glue-logic, video/image processing front-ends, communication protocol bridging (PCI, I2C, SPI, UART), low-density DSP coprocessors, and prototype ASIC emulation. Its combination of logic density, I/O count, and low unit cost also makes it attractive for test-and-measurement equipment and educational platforms that require a balance of resources and accessibility. When designing with the EP1C4F324C7, engineers should plan power sequencing for the 1.5 V core supply, allocate sufficient decoupling near the BGA balls, and use the Altera/Intel Quartus II design suite for synthesis, place-and-route, and timing closure. Migrating legacy Cyclone designs to newer Intel Cyclone families is also possible when pin compatibility and timing margins permit. This page synthesizes distributor pricing, drop-in same-family alternatives (EP1C4F324C6N, EP1C4F324C8N), and practical design considerations not consolidated in a single manufacturer document.
EP1C4F324C7N - Cyclone FPGA 4000 LEs 249 I/O FBGA-324 | Intel
The Intel (formerly Altera) EP1C4F324C7N is a Cyclone family Field-Programmable Gate Array (FPGA) with 4000 logic elements, 249 user I/O pins, and 78336 bits of embedded RAM, housed in a 324-ball FineLine BGA (FBGA-324) package measuring 19 x 19 mm with 1.0 mm ball pitch. The device operates from a 1.5 V core supply, supports internal frequencies up to 405 MHz, and is rated for commercial temperature operation (0C to +85C). A Field-Programmable Gate Array (FPGA) is a class of programmable logic device that integrates configurable logic blocks (CLBs), programmable interconnects, and dedicated memory and DSP blocks on a single silicon die. Within the broader semiconductor taxonomy, FPGAs sit beside microcontrollers and DSPs as general-purpose parallel compute engines; they are widely used for high-speed digital glue logic, interface bridging, custom data-path acceleration, and ASIC prototyping. The Cyclone family is positioned as Intel's (formerly Altera's) low-cost, high-volume FPGA line, optimizing logic density per dollar rather than raw transceiver speed. Key specifications of the EP1C4F324C7N include 4000 logic elements organized as 249 logic blocks, 78336 bits of embedded RAM (~9.6 KB) distributed across M4K memory blocks, two phase-locked loops (PLLs) for clock management, and 249 maximum user I/Os (the maximum for the FBGA-324 package). The device is fabricated on a 1.5 V, 0.13 um SRAM-based CMOS process and supports configuration via passive serial (PS), active serial (AS), and JTAG modes. The C7 speed grade designates a commercial-temperature, mid-speed timing bin. Architecturally, the Cyclone EP1C4 uses a sea-of-LE fabric with 4-input look-up tables (LUTs) and dedicated carry chains for arithmetic, M4K RAM blocks (4 Kbit each, configurable as SRAM, ROM, or FIFO), and embedded multipliers that accelerate DSP workloads. Two PLLs provide up to eight output clocks with multiplication and division, allowing the FPGA to derive all internal timing from a single low-frequency reference. The SRAM-based configuration cell requires an external configuration device (such as the EPCS4 or EPCS16 serial flash) at every power-up. Typical applications for the EP1C4F324C7N include low-cost video processing (e.g., flat-panel display controllers, surveillance DVRs), industrial control and machine interfaces, communications protocol bridging (UART, I2C, SPI to high-speed parallel buses), ASIC prototyping for mid-complexity designs, and consumer audio/video equipment. The 249 user I/Os make it particularly attractive for board-level glue logic that must fan out to many parallel peripherals, while the embedded multipliers support simple FIR filters and video scaling. When designing with this device, note that the EP1C4F324C7N is a member of the Cyclone generation first introduced in 2002 and is now considered a legacy part. Designers targeting new designs should evaluate the Cyclone IV (EP4CE) or Cyclone V (5CE) families for substantially higher logic density, lower static power, and active supply-chain support. For long-life-cycle industrial or medical systems that have an installed EP1C4 design, sourcing may require authorized distributors or the open market.
