The Altera (Intel) EP20K100CT144C7ES is a member of the APEX-20K family of Field Programmable Gate Arrays (FPGAs) housed in a 144-pin LQFP package, providing 100,000 typical gates and 93 user I/O pins. It integrates 4,160 logic elements and 53,248 bits of embedded RAM, fabricated on a 0.18 µm CMOS process that delivers a balance of logic density, on-chip memory, and I/O bandwidth for mid-complexity programmable logic designs. An FPGA (Field Programmable Gate Array) is a type of programmable logic device that allows engineers to implement custom digital circuits after manufacture using a hardware description language. FPGAs sit in the broader taxonomy of programmable logic devices (PLDs), occupying the high-density tier above simple PLDs (SPLDs) and Complex PLDs (CPLDs). The APEX-20K series combines fine-grained look-up-table (LUT) logic with high-density embedded memory blocks, making it well suited to data-path, glue-logic, and bus-interface applications. Key features of the EP20K100CT144C7ES include up to 100,000 system gates, 4,160 logic elements (LEs), 53,248 total RAM bits distributed across embedded array blocks (EABs), 93 user I/O pins, MultiVolt I/O support, in-system programmability via the IEEE 1149.1 JTAG interface, and a 144-pin LQFP (Low-profile Quad Flat Pack) surface-mount package. The device operates from a 2.5 V core supply (2.375V to 2.625V) with MultiVolt I/O banks that can interface to 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without external level shifters. Architecturally, the APEX-20K device combines logic array blocks (LABs), embedded array blocks (EABs), and FastTrack interconnect routing. Each LAB contains 10 LEs with fast carry chains for arithmetic functions, while each EAB provides up to 2,048 bits of dual-port RAM that can be configured as RAM, ROM, or FIFO. The FastTrack continuous routing architecture provides predictable timing across the die, simplifying timing closure for synchronous designs. Typical applications include telecommunications line cards, industrial control and factory automation, networking bridges and routers, low-volume ASIC prototyping, military and aerospace avionics subsystems, and high-speed glue logic between microprocessors and peripherals. The wide MultiVolt I/O support also makes this part useful for mixed-voltage board designs where 5 V legacy logic must coexist with 2.5 V cores. When designing with the EP20K100CT144C7ES, plan for power-sequencing on the 2.5 V VCCINT rail before driving I/O banks, and follow Altera's JTAG configuration guidelines. Note that this part has reached end-of-life status with limited remaining stock; planning a long-term lifecycle migration to a Cyclone-series or modern Agilex/Stratix FPGA is recommended for new designs. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers source legacy Altera APEX-20K devices while planning long-term design migrations.
EP20K100CT144C8 - APEX-20K 100K Gates FPGA | Altera | 144-LQFP
The Intel (Altera) EP20K100CT144C8 is a member of the APEX-20K family of Field-Programmable Gate Array (FPGA) ICs, integrating up to 100,000 typical gates with 53,248 system gates and 4,160 embedded RAM bits, housed in a 144-pin LQFP (TQFP) package. The device provides 93 user I/O pins and is built on a 0.18 µm CMOS SRAM-based Look-Up-Table (LUT) architecture with embedded MultiCore™ interconnect and Embedded System Blocks (ESBs) that can be configured as dual-port RAM, ROM, or FIFO memory. Speed grade -8 denotes the standard commercial timing bin, and the 'C' suffix indicates a commercial (0 °C to +85 °C) operating temperature range. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that combines the architectural flexibility of a gate array with the design-time programmability of an in-system reprogrammable IC. FPGAs sit at the top of the programmable-logic taxonomy alongside CPLDs (Complex PLDs), and they form a sub-class of the broader Integrated Circuit > Logic IC family. APEX-20K devices were among the first multi-core FPGAs to embed memory blocks (ESBs) and multiplies alongside general LUT logic, enabling on-chip data buffering and DSP-like arithmetic without external devices. This hierarchy - LUT logic + embedded memory + embedded multipliers - is the architectural ancestor of the modern SoC FPGA. Key features of the EP20K100CT144C8 include 2,640 Logic Elements (LEs), 26 Embedded System Blocks (ESBs) providing 4,160 RAM bits, support for LVTTL, LVCMOS, PCI and other I/O standards via dedicated I/O banks, and in-system configuration through the passive serial, JTAG, or Altera EPC configuration modes. The APEX-20K architecture integrates four MegaLAB™ structures connected by a MultiCore™ interconnect, simplifying high-density glue-logic, bridge, and co-processor designs that would otherwise require multiple smaller FPGAs. From an engineering perspective, the EP20K100CT144C8 is built on a 0.18 µm CMOS process and offers SRAM-based configuration memory. Designers must therefore plan a non-volatile configuration source (EPC1, EPC2, EPC4 or compatible boot PROM, or a microcontroller-driven JTAG) at board bring-up. The 144-LQFP package is a 1.4 mm-thick surface-mount JEDEC standard outline with 0.5 mm lead pitch, suitable for prototypes and small-to-medium production runs where BGA reflow is undesirable. Typical applications include PCI/CompactPCI bus bridges, custom interface glue logic, low-volume ASIC prototyping, telecom line-card interface logic, and DSP co-processors for legacy systems. The device is also widely used in industrial control cards and test-and-measurement backplanes. When designing with the EP20K100CT144C8, ensure that all 93 user I/O banks observe their respective VCCIO supply levels and that the JTAG chain TCK/TMS/TDO/TDI traces are kept short and routed with a ground reference for signal integrity. Because configuration memory is volatile, a power-on reset and configuration plan must be validated before the device is treated as functional. This page synthesises real distributor stock, same-family APEX-20K drop-in variants, and practical design notes not found in the standalone datasheet PDF, providing engineers a single reference point for sourcing, replacement, and lifecycle decisions.

The device integrates 4,160 logic elements, 416 LABs/CLBs, and 53,248 bits of embedded RAM, delivering substantial programmable capacity for complex digital designs. The 'C8' speed grade and 'ES' engineering sample suffix indicate a -40C to +85C industrial temperature range and an early-silicon / pre-production variant intended for evaluation and prototyping rather than volume production. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines configurable logic blocks, programmable interconnects, and embedded memory resources on a single semiconductor die. FPGAs sit in the broader hierarchy of digital ICs -> programmable logic -> PLD -> FPGA, alongside CPLDs (Complex PLDs) and SPLDs (Simple PLDs). APEX-20K was Intel's (formerly Altera) first-generation architecture to combine look-up-table (LUT) logic with embedded array blocks (EABs) acting as dual-port RAM, ROM, or multiplier primitives, enabling soft-core CPU implementation, DSP pipelines, and high-bandwidth glue logic on a single chip. Key features of the EP20K100CT144C8ES include 93 user-configurable I/O pins with support for multiple I/O standards, 4,160 logic elements distributed across 416 LABs (Logic Array Blocks), and 53,248 RAM bits organized in EAB blocks. The device is configured via a serial or byte-wide configuration interface, supports JTAG boundary-scan (IEEE 1149.1) for board-level testing, and operates from a 1.8V core supply with multi-voltage I/O support. The 144-LQFP package provides a 0.5 mm lead pitch and a 20x20 mm body suitable for cost-sensitive prototyping boards. From an architectural standpoint, the APEX-20K family uses a MultiCore architecture where each Logic Array Block contains ten Logic Elements, each LE comprising a 4-input LUT, a programmable register, and dedicated carry-chain logic. The embedded array blocks (EABs) provide 2,048 bits of dual-port RAM each and can be cascaded to build wider or deeper memory structures, supporting FIFO buffers, lookup tables, and small data-path scratch memories. Typical applications include telecommunications line cards, industrial control and factory automation glue logic, prototyping of ASIC designs before mask production, DSP co-processing pipelines, and legacy system upgrades where a 5V-tolerant I/O environment is needed. The wide package and configurable I/O standards make the EP20K100CT144C8ES a flexible platform for mixed-voltage designs. When designing with this engineering-sample device, note that the 'ES' suffix signals pre-production silicon - Intel/Altera datasheet errata may apply and long-term supply is not guaranteed. Use the device only for prototyping and qualification work; transition to the production-grade suffix before any volume commitment. Quartus II (or the older MAX+PLUS II for legacy APEX support) is the recommended toolchain. This page synthesizes distributor inventory data, drop-in same-package alternatives from the APEX-20K family, and practical design notes drawn from the Intel APEX-20K datasheet that are not aggregated on any single distributor listing.

The device operates across commercial temperature (0C to +85C) with a -9 speed grade targeting designs that need higher logic density than CPLDs without migrating to a fine-pitch BGA. An FPGA (Field-Programmable Gate Array) is a programmable logic device consisting of an array of configurable logic blocks (CLBs), embedded memory blocks, programmable interconnect, and I/O cells - all controlled by user-defined SRAM or antifuse configuration. FPGAs occupy the middle ground between fixed-function ASICs and smaller CPLDs, offering hardware-level parallelism, in-system reprogrammability, and on-chip memory. They sit within the broader taxonomy of programmable logic devices -> logic semiconductors -> integrated circuits, and are used wherever deterministic, high-throughput parallel processing is required.

The device is fabricated on a 0.22 um CMOS process with a 2.5 V core supply and 3.3 V I/O supply, supporting in-system programmability via the IEEE 1149.1 JTAG interface. The APEX-20K architecture combines Look-Up Table (LUT)-based logic with embedded memory and dedicated high-speed paths, making the EP20K100CT144C9 a strong fit for telecom line cards, DSP co-processing, protocol bridging, and high-speed glue logic. The four PLLs allow multi-domain clock generation, while the 93 single-ended I/O pins provide ample connectivity for memory, microprocessors, and standard bus interfaces such as PCI and ISA. Typical applications include industrial automation controllers, telecommunications interface cards, PCI-based data-acquisition boards, and embedded DSP front-ends. The combination of moderate logic density, embedded RAM, and a low-cost 144-LQFP plastic package makes it well suited for prototype and low-volume production where BGA reflow or fine-pitch assembly is undesirable. When designing with this part, ensure the 2.5 V VCCINT and 3.3 V VCCIO rails are decoupled with 0.1 uF ceramic capacitors placed as close to each supply pin as possible, and that JTAG chain integrity is verified before configuring the device. The -9 speed grade indicates moderate static timing performance; consult the APEX-20K datasheet for detailed timing closure on register-to-register paths above 100 MHz. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the original Altera datasheet, helping sourcing engineers evaluate second-source options and design trade-offs for legacy APEX-20K designs.

It is fabricated on a 0.22 µm CMOS process with a 1.8 V core supply, delivers 246 user I/Os, and operates at up to 250 MHz internal frequency. A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that can be re-programmed post-manufacturing to implement arbitrary digital logic. FPGAs sit hierarchically within programmable logic devices (PLDs) -> complex programmable logic devices (CPLDs) and FPGAs -> application-specific integrated circuits (ASICs) as a flexible alternative for low-to-medium volume digital designs where ASIC NRE cost is unjustified. The APEX-20KE family extends the original APEX 20K line with MultiCore architecture combining look-up table (LUT) and product-term (LUT+PT) logic plus embedded system blocks (ESBs) that double as either dual-port RAM or Content-Addressable Memory (CAM). Key differentiating features include 4,160 logic elements, 53,248 bits of embedded memory, 26 embedded system blocks, and 246 user I/Os in the 356-LBGA thermally-enhanced package.

The BGA-356 package measures 45 × 45 mm with 1.27 mm pitch. Architecturally, the APEX-20KE combines MegaLAB structures (groups of 16 Logic Array Blocks), embedded system blocks for memory, and FastTrack interconnect, all clocked by a 4-phase clock network supporting LVCMOS, LVTTL, PCI, SSTL-2/3, and GTL+ I/O standards. The -3N speed grade indicates a 1.6 ns propagation delay. Typical applications include telecommunications line cards, industrial control and factory automation backplanes, military/aerospace signal processing prototypes, and high-speed data acquisition front-ends where parallel datapath and on-chip buffering are essential. When designing with this part, verify pin assignment against the 356-LBGA BGA map and provide matched-length traces for high-speed clocks. Note that the EP20K100EBC356-3N is classified as obsolete/end-of-life; engineers should evaluate Cyclone-series or newer Stratix devices for new designs, while reserving this part for legacy board repair only. This page synthesizes distributor stock levels, drop-in alternative candidates from the same APEX 20KE family, and practical design notes that are not aggregated on any single manufacturer or distributor page, giving component engineers an information-gain summary tailored to long-term sourcing decisions.

Designers should note that the APEX 20KE family is now legacy/obsolete; new designs are typically migrated to Cyclone, Stratix, or MAX 10 FPGAs. This page synthesises distributor pricing, drop-in alternatives within the same 652-BGA footprint, and practical design notes not consolidated in any single vendor document.
EP20K100EFC144-1 - APEX 20KE FPGA, 100K Gates, 144-FBGA | Intel
The Intel EP20K100EFC144-1 is a member of the APEX 20KE family of programmable logic devices (PLDs), delivering up to 100,000 typical gates (263,000 maximum system gates) in a 144-ball FineLine BGA package with 93 user I/Os. Manufactured on a 0.15-µm all-layer copper process, it provides approximately 4,160 logic elements (LEs) and embedded system blocks (ESBs) for on-chip memory and dedicated logic, alongside four phase-locked loops for clock management. A field programmable gate array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs) connected by programmable interconnect. Unlike a CPLD, an FPGA stores its configuration in SRAM cells and is therefore volatile, requiring a configuration ROM or flash on every power-up. The APEX 20KE family extends the original APEX 20K architecture by adding higher-density ESBs, lower core voltage (1.8V), and faster I/O elements, making it a multi-MHz to multi-hundred-MHz class programmable fabric. In the system hierarchy, the EP20K100EFC144-1 sits below modern Cyclone or Stratix FPGAs but above fixed-function ASICs in terms of integration flexibility. Key features of the EP20K100EFC144-1 include 1.6 ns propagation delay per LE, 0°C to 85°C commercial operating temperature range, JTAG-based IEEE 1149.1 boundary-scan test support, and multiVolt I/O supporting 1.8V, 2.5V, and 3.3V interfaces. The 144-FBGA package measures 13 mm × 13 mm with a 1.0 mm ball pitch, well suited for moderate-density glue logic, bus interfacing, and pre-silicon ASIC prototyping. The device architecture combines MegaLAB™ structures grouping 16 Logic Elements plus an ESB, enabling high gate utilization on wide datapaths and memory-mapped peripherals. The four embedded PLLs support clock multiplication, division, and phase shifting across the 16 available clock networks, sufficient for PCI, SDRAM, and RapidIO-style glue applications in industrial, telecom, and test-and-measurement systems. Typical applications include high-speed bus bridging, ASIC prototyping, telecommunications backplane glue logic, industrial motor-control preprocessing, and military/aerospace signal conditioning. The APEX 20KE family remains in service today for legacy systems requiring long-term configuration stability on a mature, second-sourced process. Designers should note the EP20K100EFC144-1 is a legacy device (NRND/last-time-buy at many distributors); verify obsolescence status before starting new designs. Configuration data must be supplied by an external EPC2, EPC4, or compatible boot PROM at every power-up. The 1.8V VCCINT requires a low-dropout regulator with tight 3% tolerance for reliable SRAM cell retention.

The Altera EP20K100EFC324-1N is a member of the APEX-20KE family of Field Programmable Gate Arrays (FPGAs) fabricated on a 0.15 µm all-layer copper-metal process. The device integrates 100,000 typical gates, 4,160 logic elements (LEs), and 53,248 bits of embedded system blocks (ESBs), packaged in a 324-ball FineLine BGA with 246 user I/O pins operating at a 1.8 V core supply. An FPGA is a programmable logic device containing an array of configurable logic blocks (CLBs), embedded memory blocks, routing resources, and programmable I/O cells. APEX-20KE belongs to the SRAM-lookup-table based programmable logic hierarchy (FPGA -> PLD → programmable logic → semiconductor IC). APEX-20KE was the second-generation MultiCore architecture, delivering up to 35% higher performance versus the original APEX 20K family while supporting interfaces such as LVDS, SSTL, and HSTL. Key features include a 250 MHz internal operation, 1.6 ns propagation delay through combinational logic, JTAG IEEE 1149.1 boundary-scan test support, and embedded CAM blocks. Each ESB provides 2,048 bits of dual-port RAM configurable as RAM, ROM, CAM, or product-term logic. The PLLs and FastTrack interconnect provide deterministic timing closure for high-throughput datapaths. Architecturally the APEX-20KE device combines Logic Array Blocks (LABs) of 10 LEs each, with embedded ESBs distributed across the die. The 0.15 µm copper interconnect reduces RC delay on long routes, and the device supports MultiVolt I/O operation, allowing mixed-voltage interfacing between a 1.8 V core and 3.3 V or 5.0 V peripherals without external level shifters. Typical applications include telecommunications line-card datapath processing, high-speed data acquisition front-ends, network switches and routers, DSP co-processing, and industrial motor control. Designers choose APEX-20KE for high gate counts with low quiescent power and a deterministic timing model. When designing with the EP20K100EFC324-1N, allocate adequate BGA breakout channels on the PCB and provide four-layer routing for clean signal integrity on LVDS pairs. Use the Quartus II (or legacy MAX+PLUS II) toolchain for synthesis and place-and-route. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical PCB and thermal design notes not consolidated in the manufacturer datasheet, accelerating component evaluation and BOM management for engineers maintaining legacy APEX-20KE designs.
EP20K100EFC324-2X - APEX 20KE 100K Gates FPGA | Intel / Altera
The Intel / Altera EP20K100EFC324-2X is a member of the APEX 20KE family of Field Programmable Gate Arrays (FPGAs), delivering 100,000 system gates, 4,160 logic elements (cells), and 53,248 bits of embedded RAM in a 324-ball FineLine BGA (FBGA) package. The device is fabricated on a 0.22 µm (per FindIC) all-layer copper-metal CMOS process and operates with a core supply of 1.8 V, with the speed grade "-2X" offering up to 250 MHz internal operation. The package pin pitch is 1.27 mm and the device exposes up to 246 user I/O pins (per DigiKey, Mouser and Intel / Altera datasheets). An FPGA (Field Programmable Gate Array) is a type of Programmable Logic Device (PLD) that combines a large array of configurable logic blocks (LABs/CLBs), embedded memory blocks, I/O elements, and programmable interconnect into a single semiconductor IC. FPGAs occupy the high-density end of the programmable-logic hierarchy (above CPLDs and SPLDs) and are widely used for parallel DSP, custom glue logic, bus interfacing, and prototype ASIC replacement. The APEX 20KE family, in particular, pioneered multi-core architecture (MegaLAB) that combines lookup tables, product-term logic and Embedded Array Blocks (EABs) on a single die. Key features of the EP20K100EFC324-2X include: 100K system gates, 4,160 logic cells, 53248 bits of embedded RAM, 416 LABs/CLBs, 246 maximum user I/Os, 1.8 V core supply, in-system programmability via IEEE 1149.1 JTAG, MultiVolt I/O support for interfacing to 1.8 V / 2.5 V / 3.3 V logic, and a 4-input Look-Up Table (LUT)-based fine-grain architecture. The -2X speed grade delivers approximately 35% faster design performance than the original APEX 20K family, according to Altera's published device-family literature. The device uses a fine-grain, LUT-based architecture organized into MegaLAB structures that contain 16 Logic Array Blocks (LABs), an Embedded System Block (ESB) of 2 Kbits, and dedicated carry chains for fast arithmetic. Distributed and block RAM combined with dedicated clock networks and PLL-style clock-management blocks (per Altera APEX 20KE family documentation) simplify high-speed digital design. Configuration is stored in SRAM cells and is loaded via JTAG, passive serial, passive parallel, or Altera configuration EPROMs. Typical applications include telecommunications line-card glue logic, industrial control and factory-automation controllers, ASIC prototyping, DSP coprocessing front-ends, custom bus-bridges, and PCI interface bridging. Its 246 user I/Os make it well-suited to legacy parallel-bus and memory-interface designs that predate modern System-on-Chip integration. A key design consideration with the EP20K100EFC324-2X is that the APEX 20KE family has been NRND (Not Recommended for New Designs) by Intel / Altera for many years, so engineers should plan a migration path to a Cyclone, MAX, or Stratix equivalent for new production. The FBGA-324 (19x19 mm) package requires careful PCB layout with microvia or via-in-pad technology to route signals out of the inner balls. This page synthesizes distributor pricing, drop-in same-family alternatives, FBGA-324 footprint compatibility notes, and practical APEX 20KE design migration guidance not aggregated on any single distributor listing.
EP20K100EQC208-1X - 100K APEX-20KE FPGA, 151 I/O | Intel
The Intel (formerly Altera) EP20K100EQC208-1X is a member of the APEX-20KE family of Field-Programmable Gate Arrays (FPGAs), delivering 100,000 logic gates, 4,160 logic elements (LEs), and 53,248 bits of embedded system memory in a 208-pin PowerQuad Flat Pack (PQFP) package. According to verified distributor listings, the device exposes 151 user I/O pins and is built on a 0.15-micrometer all-layer copper-metal CMOS process, a fabrication node that yields up to 35% faster design performance than the original APEX 20K series. The "-1X" suffix denotes an industrial-grade speed grade and lead-free, enhanced lead-frame configuration suitable for production designs. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose logic, interconnect, and I/O behavior are defined by user-supplied configuration data rather than at fabrication time. Within the broader programmable logic taxonomy, an FPGA sits below ASICs in NRE cost but above them in flexibility, and the APEX 20KE architecture specifically combines Look-Up Table (LUT)-based logic elements with embedded memory blocks called Embedded System Blocks (ESBs), enabling efficient implementation of datapath, state-machine, and small-memory functions in a single device. Key features of the EP20K100EQC208-1X include 4,160 LEs arranged in MegaLAB structures, 26 ESBs totaling 53,248 bits of RAM (each ESB configurable as dual-port or single-port RAM, ROM, or CAM), four Phase-Locked Loops (PLLs) for clock multiplication and deskew, and MultiVolt I/O supporting 1.8V, 2.5V, 3.3V, and 5.0V interfaces without external level shifters. The device operates from a 1.8V core supply with separate VCCIO banks, supports in-system programmability via the IEEE 1149.1 JTAG boundary-scan interface, and integrates configuration circuitry compatible with passive-serial, passive-parallel, and Altera-specific configuration schemes including the EPC2 configuration PROM. Typical applications include high-speed digital signal processing pipelines, telecommunications backplane glue logic, industrial control and instrumentation front-ends, and legacy PCI/ISA bridge designs. The 208-pin PQFP package offers inspectable gull-wing leads suited for prototyping, low-volume production, and through-hole-friendly rework workflows that newer BGA-only FPGAs cannot accommodate. Designers typically pair this part with Intel configuration PROMs (such as the EPC2 family) and Quartus II or MAX+PLUS II development environments for synthesis, place-and-route, and bitstream generation. When designing with this device, ensure the PCB thermal budget accounts for up to 1.6W worst-case dissipation, provide a minimum of four PCB layers with a dedicated ground plane for signal integrity, and observe 5V-tolerant I/O bank power sequencing to avoid latch-up. Engineers evaluating new designs should weigh the APEX 20KE's mature tool flow against newer Cyclone or MAX families where pin compatibility does not exist.

EP20K100EQC208-2 - 100K-Gate 1.8V FPGA | Altera APEX 20KE
Altera EP20K100EQC208-2 is an APEX-20KE field-programmable gate array (FPGA) with 4,160 logic elements, 53,248 embedded RAM bits, 151 user I/O pins, and a 250 MHz performance rating, housed in a 208-pin BFQFP (PQFP-208) surface-mount package. The device is built for legacy and medium-density FPGA applications that require commercial-temperature (0°C to 85°C) programmable logic with a high I/O count and on-chip memory blocks. The -2 suffix identifies the speed grade used by the Altera APEX 20K family. A 1.8 V core supply, with an operating range of 1.71 V to 1.89 V, places this component in the low-voltage FPGA category. What is an SRAM-based FPGA? A field-programmable gate array is an integrated circuit containing configurable logic blocks, programmable interconnects, and user I/O that can implement arbitrary digital logic after manufacturing. The EP20K100EQC208-2 belongs to the APEX-20KE family, positioned above simple CPLDs in logic capacity and intended for board-level integration without mask changes. Because SRAM-based FPGAs lose their configuration at power-off, the device must be reloaded from external configuration memory at every power-up, making configuration devices or a serial configuration source essential in the end application. Key features of the EP20K100EQC208-2 include 4,160 logic elements for state machines, counters, datapath decoding, and custom control functions, plus 53,248 RAM bits that can implement FIFOs, small frame buffers, or distributed memory. The 151 user I/O channels are routed out to the 208-pin PQFP package, providing enough pins for parallel buses, backplane interfaces, and mezzanine connectors. The 1.8 V core voltage reduces logic power in dense systems, while the 250 MHz rated performance supports moderate-clock telecom and industrial designs. On the technical side, EP20K100EQC208-2 uses the APEX 20KE logic-element fabric with embedded memory blocks, allowing designers to combine register-heavy and memory-heavy functions in one component. The PQFP-208 package uses gull-wing leads, which are inspectable after soldering and therefore practical for legacy board repair and controlled factory assembly. Because the FPGA is programmable in-circuit, prototype iterations require only a configuration update rather than new PCB fabrication. Speed-grade binning determines the specific combinatorial and registered timing limits for this -2 device. Typical applications for EP20K100EQC208-2 include telecom line cards, industrial controller boards, networking switch fabric glue logic, and test-and-measurement front ends. Designers often use it to replace obsolete ASICs or multiple CPLDs while keeping the existing PCB footprint, especially when a 208-pin PQFP APEX-20KE socket is already present. Buffer management, address decoding, interface bridging, and alarm and status processing are all practical uses of the 4,160 logic elements. A key design consideration is the mandatory configuration source: an SRAM FPGA such as EP20K100EQC208-2 cannot operate immediately after power-up unless an EPC configuration device, microprocessor, or serial configuration source loads the bitstream. Timing closure must also be run with the -2 speed-grade constraints rather than assuming generic APEX timing. Use 1.8 V core decoupling close to every VCCINT pin and follow the power-up sequencing rules in the APEX 20K family documentation. This XAIPART page aggregates distributor availability, drop-in APEX package alternatives, and practical legacy-system guidance that supplement the manufacturer datasheet, giving engineers a single comparison point for an older but still widely stocked programmable logic family.
EP20K100EQC208-3 - APEX 20KE FPGA 151 IO 208-PQFP | Intel
The Intel (formerly Altera) EP20K100EQC208-3 is an APEX-20KE field-programmable gate array (FPGA) with 4,160 logic elements, 53,248 RAM bits, and 151 user I/O pins, delivered in a 208-pin BFQFP/PQFP package. Its 1.8 V core supply and -3 speed grade make it suitable for mid-density programmable logic in legacy telecommunications, industrial, and test equipment applications. An FPGA is a semiconductor device containing programmable logic elements, embedded memory, and programmable I/O, which can be reconfigured after manufacturing to implement custom digital logic. FPGAs belong to the programmable logic device (PLD) hierarchy above simple PLDs and CPLDs, giving designers high logic density, on-chip RAM, and flexible I/O standards. The APEX-20KE family is Intel/Altera's SRAM-based programmable logic architecture, designed for system-on-a-programmable-chip applications where multiple logic functions, memory, and interface blocks are integrated on one device. Key specifications for the EP20K100EQC208-3 include 4,160 logic elements/cells, 53,248 total RAM bits, 151 user I/O pins, a 1.8 V core supply, and a 0°C to 85°C commercial operating-temperature range. The device is listed as a 100,000-gate-class FPGA in the captured FPGAkey data, and appears in the APEX 20K family as a 208-lead BFQFP (PQFP-208) package. The -3 suffix denotes the standard speed grade variant. The device uses an SRAM-based configuration fabric, so it must be configured from an external configuration device or through JTAG after power-up. It provides 151 parallel I/Os for general-purpose logic interconnection, plus enough embedded RAM bits to buffer data, hold small FIFOs, or implement simple distributed memory. The 1.8 V core voltage reduces active power compared with earlier 2.5 V programmable-logic families, although I/O banks may still interface to legacy 3.3 V systems when VCCIO is supplied appropriately. Typical uses for this FPGA include protocol adaptation in wired networking equipment, glue logic for industrial controllers, video/image processing pipelines, test-and-measurement front ends, and prototyping platforms where a medium-capacity FPGA in a board-friendly QFP package is preferred over expensive BGA devices. The 208-pin PQFP is easier to route on two-layer PCBs and allows hand assembly in low-volume designs. When designing with the EP20K100EQC208-3, remember that configuration data is volatile; allocate an EPC2 or EPC16 configuration device or a JTAG download path for every production board. Also keep 0.1 µF ceramic bypass capacitors near the VCC pins and maintain the 1.8 V core supply tolerance required by the APEX 20K family. This page synthesizes distributor availability, same-package drop-in alternatives, and legacy-design selection guidance that is not typically presented together in a single datasheet listing.
EP20K100EQC208-3N FPGA - 1.8V APEX-20KE | Altera
The Altera EP20K100EQC208-3N is an APEX-20KE Field Programmable Gate Array (FPGA) with 4,160 logic elements, 53,248 RAM bits, 151 user I/O pins, and 100K typical gates (263K system gates per Microchip USA), in a 208-pin BFQFP/PQFP package requiring a 1.8V core supply. The -3N suffix indicates the -3 speed grade and lead-free finish, with a commercial operating temperature range of 0 °C to +85 °C. An FPGA is an integrated circuit containing programmable logic blocks, configurable interconnect routing, and embedded memory. After manufacturing, designers load a bitstream into SRAM configuration cells to define the desired digital functions, so the same device can implement many different circuits. Within the programmable logic hierarchy, an FPGA offers more capacity than a CPLD and is used where thousands of logic elements and dense synchronous logic are required. It is part of the Integrated Circuits > FPGA & CPLD product tree. The EP20K100EQC208-3N belongs to the now-obsolete APEX-20KE family but remains important for sustaining existing hardware. Key features of EP20K100EQC208-3N include 4,160 logic elements, 53,248 RAM bits, 151 user I/O pins, and support for a 250 MHz maximum system frequency as listed by Arrow and Lisleapex. The 1.8V core supply reduces power compared to earlier 2.5V and 3.3V FPGAs. The 208-pin BFQFP (also called PQFP-208) package provides a practical balance between I/O count and manufacturability, with gull-wing leads suitable for conventional surface-mount assembly. The -3 speed grade is the standard operational bin for legacy APEX-20KE designs. The APEX-20KE architecture combines LUT-based logic elements with product-term macrocells and embedded system blocks, allowing it to integrate state machines, arithmetic functions, FIFOs, and memory controllers. The EP20K100EQC208-3N is SRAM-based and does not retain configuration after power-off, so it must load firmware from EPC or EPC2 configuration devices at power-up. Because the device is volatile, JTAG-based in-system programming and configuration download are both supported. The 263K system gate figure reported by Microchip USA provides a higher-level gate-count perspective needed for system-level sizing. Typical applications include legacy telecommunications line cards, industrial control I/O modules, legacy medical diagnostic systems, university FPGA/digital design courses, ASIC prototyping, and aerospace or defense sustainment projects. In these uses, the 151 user I/O pins and embedded RAM support bus interfacing, state-machine control, and image/interface preprocessing. Its 0 °C to +85 °C commercial range is suitable for controlled indoor equipment. Designers should provide a clean 1.8V core supply with adequate decoupling at every VCCINT pin, apply the required VCCIO voltages for the external interface standard, and include a reliable configuration memory. Because this family is obsolete, confirm final stock and ensure bitstream compatibility before using it in a new build. This page synthesizes distributor sourcing status, pricing estimates, drop-in APEX-20KE speed-grade alternatives, and practical design guidance that are not collected in a single FPGA datasheet.

An FPGA is a reconfigurable digital integrated circuit whose logic elements, routing resources, and I/O functions are programmed after manufacturing. FPGAs sit between fixed-function ASICs and software processors in the system hierarchy: they provide massive parallel custom hardware while remaining field-upgradable. The APEX-20KE family belongs to older Altera mid-density FPGAs and supports the PLD/CPLD and gate-array replacement role in legacy and industrial systems. The EP20K100EQC240-2X offers 4,160 logic elements to implement control, data-path, and interfacing logic. Its 53,248 RAM bits allow small FIFOs, line buffers, or register files without external memory. With 183 user I/Os, it can connect to multiple parallel buses, ADC/DAC interfaces, and backplane signals. The 240-pin QFP package is easy to solder and inspect compared with fine-pitch BGA alternatives. Technically, the APEX-20KE architecture combines look-up-table based logic, embedded memory, and a fast interconnect fabric. Fabricated on a 0.22 µm CMOS process, the FPGA integrates up to 100K typical system gates and supports vendor design flows. The -2X suffix denotes a specific speed/ordering grade; actual timing should be confirmed from the APEX 20K datasheet when targeting a frequency above 250 MHz. The EP20K100EQC240-2X is commonly used in telecom line cards, industrial controllers, data acquisition systems, signal-conversion front-ends, and legacy FPGA sockets. Its 5.0 V-tolerant I/O simplifies direct connection to legacy 3.3 V or 5.0 V logic families. The 1.8 V core also helps reduce dynamic switching power compared with earlier 2.5 V or 3.3 V programmable devices. Designers should verify the complete voltage and power-up requirements, including VCCINT and VCCIO rails, before layout. Because this is a legacy APEX device, users should confirm configuration-device compatibility and BSDL/model availability for boundary-scan testing in new board designs. This page combines current distributor availability, verified package and I/O data, drop-in APEX-20K family alternatives, and practical design notes that are not all repeated in a single manufacturer datasheet view, giving engineers a faster component evaluation workflow.

It is manufactured using CMOS technology and is designed for high-density programmable logic in embedded systems. The verified source data identifies a 1.8 V supply and a 240-BFQFP package; the part is associated with the APEX-20KE family. Its programmable architecture supports configurable digital logic, interface bridging, control processing, and application-specific datapaths. An FPGA, or field-programmable gate array, is a semiconductor device containing configurable logic blocks, programmable interconnects, and input/output resources that can be configured after manufacturing. FPGA devices belong to the broader programmable-logic-device hierarchy, which also includes CPLDs and other loadable PLDs. Unlike a fixed-function ASIC, an FPGA can be reprogrammed to implement changing logic functions. The APEX-20KE family combines high logic capacity with embedded memory resources and configurable I/O, making it suitable for systems that require adaptable digital processing without a custom mask set. The principal device characteristics are 100K gates, 4160 cells, 53248 RAM bits, and 183 user I/O pins. The reported 250 MHz value describes the device's listed FPGA performance. A 1.8 V operating supply supports low-voltage digital designs, while the 240-BFQFP package provides a high-pin-count surface-mount footprint. The combination of logic capacity, embedded RAM, and numerous I/O channels enables integration of control logic, data formatting, protocol adaptation, and interface functions in one programmable device. EP20K100EQC240-3N is based on programmable-logic architecture rather than a fixed processor instruction set. Configuration data defines logic behavior and interconnect routing, allowing the same hardware platform to support multiple product variants. The 53248 RAM bits provide on-chip storage for state machines, FIFOs, lookup tables, buffering, and timing functions. Because the device is a CMOS FPGA, system designers should follow the manufacturer's configuration, clocking, power-supply, decoupling, and signal-integrity guidance when creating a new design. Typical applications include industrial automation controllers, communications interface equipment, test and measurement systems, and embedded signal-processing platforms. Its 183 user I/O pins can support numerous parallel or serialized external interfaces, while the embedded RAM can reduce the need for small external memory structures. The 250 MHz rating is relevant to high-speed digital logic and timing-sensitive control functions, although actual system performance depends on routing, configuration, clock topology, and operating conditions. When selecting this part, confirm that the 240-BFQFP footprint, pinout, configuration method, supply requirements, and timing constraints match the target PCB. The package designation and the separate Digipchip listing for a BGA-652 device are inconsistent, so the 240-BFQFP identification is used here because it appears in the DigiKey, Mouser, FPGAkey, and Microchip USA results. Engineers should verify the exact package drawing and pin numbering before substitution. This product record combines verified distributor specifications, package information, sourcing status, and design-oriented context to support engineering review. It also identifies where package and availability details require confirmation, helping buyers and FPGA developers avoid substituting a device solely on the basis of family name or nominal logic capacity.

The device supports in-system programming via the IEEE 1149.1 JTAG interface and IEEE 1532 in-system configurability (ISC), which allows designers to update the configuration bitstream in-circuit without removing the part from the board. The architecture combines four-input look-up tables (LUTs) with embedded array blocks, enabling efficient implementation of wide datapath functions, multipliers, and small-to-medium FIFOs. Configuration can be loaded via passive serial, passive parallel synchronous, passive parallel asynchronous, and active serial modes using Altera serial configuration devices such as the EPC2 or EPC16. Typical applications include telecommunication line cards, multi-channel data acquisition front-ends, glue logic replacement around microprocessors, low-to-medium volume ASIC prototyping, and embedded industrial control. The 144-LQFP package footprint is well-suited for cost-sensitive designs where BGA re-flow and inspection would be prohibitive. Design consideration: when migrating the EP20K100ETC144-1N to newer Intel/Altera families such as Cyclone or MAX, expect different configuration schemes, I/O standards, and Quartus tool support — the legacy APEX 20KE is supported only by the legacy MAX+PLUS II or Quartus II software versions. Allow substantial PCB rework if you must change footprint. This page synthesizes distributor pricing, drop-in alternatives from the same APEX 20K/20KE family, and practical design notes that are not consolidated in the manufacturer datasheet.

The APEX-20K family combines Look-Up Table (LUT) logic with embedded system blocks for memory and arithmetic, supporting high-density programmable logic at typical densities up to 100,000 system gates. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs), interconnect routing, and programmable I/O cells that allow designers to implement arbitrary digital logic via a hardware description language (HDL) and a configuration bitstream. Within the broader taxonomy, FPGAs sit alongside CPLDs in the programmable logic category, which itself falls under Logic ICs, a sub-domain of digital Integrated Circuits. FPGAs are typically used when design requirements exceed the capacity or performance of fixed-function ASICs, microcontrollers, or CPLDs. Key features of the EP20K100FC144-1X include 4,160 logic elements (LEs), 416 Logic Array Blocks (LABs), 53,248 embedded RAM bits, and 93 user I/O pins. The device integrates MultiCore architecture combining LUT-based logic with embedded system blocks (ESBs) usable as either dual-port RAM, ROM, or CAM blocks. The 144-pin TQFP (FC) package supports fine-pitch surface-mount assembly with a 0.5 mm lead pitch. The APEX-20K family is built on a 0.18 µm CMOS process with an SRAM-based configuration cell, requiring a configuration device or microprocessor for bitstream loading on each power-up. The 'C' package suffix indicates a commercial temperature grade (0 °C to +85 °C). I/O standards supported include LVTTL, LVCMOS, PCI, and various LVDS signaling levels via dedicated I/O banks. Typical applications include telecommunications switching, image processing pipelines, industrial control logic, and embedded system glue logic. The 93 available I/Os make it suitable for moderately wide bus interfaces, while the 53 Kbit of embedded RAM supports small FIFOs and state buffers without consuming external memory. When designing with this device, pay attention to configuration scheme selection (Passive Serial, Passive Parallel, or Boundary-Scan) because the configuration interface pins are multiplexed with user I/O after configuration. Power sequencing and decoupling must follow the Altera APEX-20K reference design guidelines.

The Intel (formerly Altera) EP20K100FC144-2 is a member of the APEX-20K family of Field Programmable Gate Array (FPGA) integrated circuits, providing 4,160 logic elements, 416 logic array blocks (LABs), and 53,248 bits of embedded RAM in a 144-pin TQFP (20x20 mm) surface-mount package. It supports up to 93 user I/O pins and is fabricated on a 0.18-micron CMOS process, targeting high-density programmable logic applications that require moderate speed grade (-2) and commercial 0C to 85C operating temperature. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the high density of gate arrays with the configurability of logic blocks, allowing hardware designers to implement custom digital circuits after manufacturing. FPGAs sit above CPLDs and PALs in the programmable logic hierarchy, offering 100x to 1000x more logic resources, embedded memory blocks, and high-speed I/O serializers. APEX-20K devices specifically combine look-up table (LUT) logic with embedded dual-port RAM (ESBs - Embedded System Blocks), enabling efficient data-path and datapipelined designs. Within Intel's broader FPGA portfolio, APEX-20K preceded the Cyclone, Arria, and Stratix families, and is now considered a mature legacy platform. Key features of the EP20K100FC144-2 include 4,160 logic elements distributed across 416 LABs, 53,248 bits of embedded system block (ESB) RAM configurable as dual-port SRAM or ROM, and 93 user I/O pins compliant with multiple I/O standards. The device supports multi-level interconnect architecture (MegaLAB structure), four phase-locked loops (PLLs) for clock management, and JTAG IEEE 1149.1 boundary-scan testing. The -2 speed grade places it in the mid-performance tier of the APEX-20K family, balancing maximum operating frequency against power consumption. Architecturally, the EP20K100FC144-2 uses a MultiCore architecture integrating LUT-based logic, embedded memory, and a network of MegaLAB structures that route signals between LABs, ESBs, and I/O elements. This fabric supports True-LVDS, LVCMOS, LVTTL, SSTL, and GTL+ I/O standards via dedicated I/O banks. Each ESB can be configured as dual-port SRAM up to 4 Kbits, enabling efficient FIFO and cache implementations. The 144-pin TQFP package provides 93 usable I/O pins (some pins are dedicated to power, ground, JTAG, and configuration). Typical applications include telecommunications infrastructure (line cards, multiplexers, protocol bridges), industrial control systems (machine vision, motor controllers, PLCs), test and measurement instrumentation, and legacy embedded computing platforms. It is commonly used as a glue-logic aggregation device or as a flexible I/O expander on PCI, ISA, and VME bus cards. APEX-20K devices are widely deployed in long-lifecycle industrial and military programs where the design has been qualified and the FPGA firmware is stable. When designing with this part, ensure the Quartus II (or MAX+PLUS II) toolchain is available, as newer Quartus Prime versions may not support the APEX-20K family. Verify the 2.5V core supply (VCCINT 2.375V to 2.625V) is well-decoupled with low-ESR bulk and ceramic capacitors placed close to the power pins. Always consult the Altera APEX-20K datasheet for I/O bank configuration rules before finalizing PCB pin assignment.

EP20K100FC144-2X - APEX-20K FPGA 4160 LE 93 I/O 144-LQFP | Intel
The Intel (formerly Altera) EP20K100FC144-2X is a member of the APEX-20K family of Field Programmable Gate Arrays (FPGAs), delivering 4,160 logic elements, 53,248 RAM bits, and 93 programmable I/O pins in a 144-pin LQFP (FC) package. This device integrates LUT-based logic with embedded memory blocks and is designed for high-performance, low-power programmable logic applications requiring medium-density logic capacity. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that allows engineers to implement custom digital circuits through software-defined configuration. FPGAs sit at the top of the programmable logic hierarchy, which flows: programmable logic device (PLD) → CPLD → FPGA → SoC FPGA. APEX-20K devices specifically combine look-up table (LUT) logic, embedded array blocks (EABs) for memory, and FastTrack interconnect, supporting both combinational and sequential digital designs up to several hundred MHz internal performance. Key features of the EP20K100FC144-2X include 416 logic array blocks (LABs/CLBs), 4,160 logic elements, 53,248 bits of embedded RAM distributed across embedded array blocks, and 93 user I/O pins supporting multiple I/O standards. The device operates from a 2.5V core supply and 3.3V/5V-tolerant I/O, and is offered in a commercial grade speed grade -2 with the 'X' suffix indicating an unspecified or variant temperature/process option. The LQFP-144 package is surface-mount friendly and supports standard reflow profiles. The architecture employs a MultiCore interconnect routing fabric that provides predictable timing for high-performance designs, with built-in support for common functions such as FIFOs, CAMs, RAM/ROM, and standard interfaces (PCI, LVDS, etc.) via dedicated IP cores. The 144-LQFP package provides a practical pin count for memory and high-density logic designs while still allowing hand-solderable prototype boards, which is unusual for a programmable logic device of this capacity. Typical applications for this FPGA include telecommunications line cards, industrial control and machine vision pre-processing, glue logic in embedded systems, prototyping for ASIC designs, and low-volume custom DSP/communication pipeline implementations. The combination of moderate logic capacity and 93 I/O makes the EP20K100FC144-2X a strong fit for bridging legacy interfaces to modern processors, particularly where dedicated I/O banks need to support multiple voltage domains. When designing with this part, note that the APEX-20K family is legacy hardware - newer designs should consider Cyclone IV/V or MAX 10. Always use the Quartus II design software (legacy 13.0sp1 or earlier) for synthesis and place-and-route, since modern Quartus releases do not support APEX devices. Ensure the JTAG programming interface is brought out to a 10-pin header for in-system programming and boundary-scan testing.

EP20K100FC144-3 - APEX-20K 100K Gate FPGA, 93 I/O, 144-LQFP | Intel/Altera
The Intel (formerly Altera) EP20K100FC144-3 is an APEX-20K family Field Programmable Gate Array (FPGA) with 100,000 typical gates, 4,160 logic elements, and 53,248 bits of embedded RAM, housed in a 144-pin LQFP (Low-profile Quad Flat Pack) package. The device provides 93 user I/O pins and operates at the -3 speed grade, balancing logic density and timing margin for high-performance digital designs. It belongs to the APEX (Advanced Programmable Element Matrix) architecture family, which was Intel/Altera's first-generation multi-core programmable logic platform. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that engineers can reprogram post-manufacturing to implement custom digital logic functions. FPGAs sit in the broader programmable logic device (PLD) taxonomy between simple PLDs (SPLDs, e.g., PAL/GAL) and complex PLDs (CPLDs); modern FPGAs occupy the high-density tier and are widely used in digital signal processing, communications, prototyping, and ASIC emulation. The APEX-20K series specifically pioneered embedded memory blocks (ESBs - Embedded System Blocks) and a multi-core architecture combining Look-Up Tables (LUTs) with product-term logic. Key features of the EP20K100FC144-3 include 416 Logic Array Blocks (LABs), 4,160 logic elements, 53,248 RAM bits for distributed or block memory, four Phase-Locked Loops (PLLs) for clock management, JTAG-based IEEE 1149.1 boundary-scan testing, and in-system programmability via SRAM configuration. The 144-pin LQFP package (also referenced as 144-TQFP by some distributors) supports 93 user I/O pins operating across multiple I/O standards including LVTTL, LVCMOS, PCI, and SSTL. The device operates from a 2.5V core supply with separate VCCIO banks for I/O flexibility. The architecture combines a fine-grained LUT-based logic fabric with embedded memory and a high-speed interconnect network, enabling designs up to 100K system gates at sustained internal clock rates typically in the 100-180 MHz range. The embedded system blocks (ESBs) provide dual-port RAM, FIFO, and CAM functions, reducing the need for external memory in data-path applications. Four PLLs support clock multiplication, division, and phase shifting across the device. Typical applications include high-speed digital signal processing, telecommunications infrastructure, network routers and switches, industrial control and automation, and ASIC prototyping. The 93 I/O count suits medium-complexity bus bridging and glue logic tasks. Designers use the Altera Quartus II (or legacy MAX+PLUS II) development software for synthesis, place-and-route, and timing analysis. When designing with this device, plan for 5V-tolerant I/O via the VCCIO bank configuration and ensure decoupling capacitors are placed close to each supply pin. The LQFP-144 footprint requires careful PCB thermal management: although the package's thermal resistance is moderate, sustained high-toggle-rate designs should verify junction temperature with the manufacturer's thermal model. Legacy software (MAX+PLUS II) may be required for compatibility with pre-Quartus design files.
