EP20K100CQ208C8ES - APEX 20K FPGA 4160 LE | Intel
The Intel EP20K100CQ208C8ES is an APEX 20K family field-programmable gate array (FPGA) containing 4160 logic elements and up to 159 user I/O pins in a 208-pin QFP (BFQFP) package. The ordering code identifies a CQ208 variant of the EP20K100 device, supplied in tray packaging with an MSL rating of 3 (168 hours). As of 2026-09-07, this device is in the obsolete APEX 20K family and should only be designed into legacy or revision-controlled boards. An FPGA is a reconfigurable integrated circuit containing programmable logic fabric, programmable interconnect, and configurable I/O blocks. Unlike a fixed-function ASIC or MCU, an FPGA can implement many different digital logic functions by loading a configuration bitstream at power-up. An APEX 20K FPGA sits above simple CPLDs in capacity and is often used for protocol bridging, digital signal preprocessing, and bus interface aggregation. In a system hierarchy, an FPGA is one type of programmable logic device, often accompanied by configuration memory such as EPC2 or EPCS devices. The data captured for EP20K100CQ208C8ES confirms 4160 logic elements and 159 user I/O lines. The 208-pin QFP package provides a surface-mount footprint suitable for dense board layouts where ball grid arrays are not preferred. The package is available in tray format, and the MSL 3 rating means devices require baking if exposed to humidity before reflow. These facts make the part usable for legacy board repair, replacement inventories, and maintenance of existing APEX 20K systems. The APEX 20K architecture combines lookup-table-based logic elements with embedded memory-oriented blocks. For this specific ordering code, the maximum system gates, embedded RAM bits, core voltage, speed grade, and temperature grade are not explicitly stated in the captured web data. Engineers should verify those parameters from the Altera/Intel APEX 20K family datasheet before using the device in a timing-sensitive or supply-rail-sensitive design. Typical legacy applications include telecom line cards, Ethernet interface bridging, industrial controller backplanes, and high-channel-count test equipment. The 159 I/O pins provide enough connectivity for a wide parallel bus, address decoding, or an external memory interface, while the 4160 logic elements implement medium-density glue logic, state machines, and DSP supervision logic. The most important design consideration is lifecycle: Intel has classified the APEX 20K series as obsolete and recommends Cyclone IV family devices for new designs. Cyclone IV is not pin-compatible with the QFP208 footprint and requires board migration. For existing EP20K100CQ208C8ES boards, the practical action is to qualify a same-family QFP208 spare such as EP20K100CQ208C8 or EP20K100CQ208C7ES. This page synthesizes distributor availability, package data, ordering-code variants, lifecycle guidance, and design caveats that are not all included in the manufacturer datasheet, helping engineers make faster sourcing and obsolescence decisions.

It integrates 53,248 RAM bits, four phase-locked loops (PLLs), and 159 user I/O pins, supporting 0.18-micron CMOS SRAM-based logic fabric with embedded system-on-a-chip (SoC) capability. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement any digital logic function. FPGAs sit in the broader hierarchy of programmable logic devices (PLDs) -> complex programmable logic devices (CPLDs) -> FPGAs -> SoC FPGAs, and are widely used as alternatives to application-specific integrated circuits (ASICs) for prototyping, low-volume production, and high-performance parallel processing tasks such as DSP, communications, and custom compute accelerators. Key features of the EP20K100CQ208C9 include 4,160 logic elements, 26 embedded system blocks (ESBs) delivering 53,248 RAM bits, four PLLs for clock management, and a maximum of 159 user I/O. The device operates across commercial 0 to 70 C temperature range (the C9 speed grade) and supports in-system programmability via the IEEE 1149.1 JTAG interface and the Altera Passive Serial configuration scheme. The APEX 20K architecture combines look-up table (LUT) logic with embedded memory, enabling designers to integrate glue logic, FIFOs, and small register files on a single device. Architecturally, the EP20K100CQ208C9 uses a MultiCore architecture introduced by Altera in 1999, distributing MegaLAB structures across the die and providing dedicated high-speed interconnect (FastTrack) for predictable timing. The four PLLs support clock multiplication, division, phase shifting, and frequency synthesis, simplifying board-level clock tree design for synchronous logic and source-synchronous interfaces. Typical applications for the EP20K100CQ208C9 include telecommunications line cards, custom peripheral controllers for industrial automation, glue logic replacement for legacy ASICs, prototype validation of ASIC designs, PCI bridge implementations, and digital signal processing front-ends. The 208-pin PQFP package is well-suited for through-hole and socketed designs where rework and field replacement are valued over board density. When designing with the EP20K100CQ208C9, engineers should use the Altera Quartus II (legacy) or MAX+PLUS II development environment for synthesis, place-and-route, and timing analysis. Configuration data must be loaded from a serial EEPROM or downloaded via JTAG; ensure your board supports the Passive Serial configuration mode and provides proper MSEL pin strapping for the chosen mode. This page synthesizes distributor stock levels, drop-in same-package alternatives from the APEX 20K family, and practical design notes that go beyond the manufacturer datasheet, helping engineers evaluate the EP20K100CQ208C9 against modern FPGA alternatives.

According to distributor listings, the device targets complex DSP, communications, and glue-logic designs that require embedded memory, PLLs, and high pin count I/O in a surface-mount package. The 'C7' speed grade denotes a commercial-temperature part, while the 'CQ240' suffix identifies the 240-pin BFQFP package option. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) within the broader semiconductor category. FPGAs sit hierarchically as: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit -> semiconductor. APEX-20K devices specifically pioneered the combination of look-up table (LUT)-based logic with embedded memory blocks (ESBs) and embedded multipliers, enabling single-chip implementations of datapath and control functions that were previously partitioned between separate logic and memory chips. Key features of the APEX-20K family include embedded system blocks (ESBs) that can implement dual-port RAM, ROM, FIFO, or CAM; four phase-locked loops (PLLs) for clock multiplication and deskew; support for multiple I/O standards including LVTTL, LVCMOS, PCI, and GTL; and a MultiVolt I/O interface allowing core and I/O banks to operate at independent voltages. The architecture combines fine-grain logic elements with coarse-grain ESBs, giving designers flexibility to balance logic density and on-chip memory. Typical applications for the EP20K100CQ240C7 include telecommunications switching and channel cards, network interface and protocol bridging logic, DSP co-processing acceleration, video and image processing front-ends, industrial control and machine-vision interfaces, and high-performance glue logic for memory-mapped bus architectures. The 100K-gate density and 240-pin package make it well-suited to mid-complexity designs that exceed the capacity of smaller CPLDs but do not justify migrating to higher-cost, higher-density FPGAs. When designing with this part, engineers should verify Quartus/MAX+PLUS II tool support, confirm that legacy configuration bitstreams remain available, and account for the device's mature (NRND/EOL) status by validating long-term supply. The 240-pin BFQFP footprint simplifies hand-soldering and inspection, but requires careful thermal management and decoupling for high-toggle-rate outputs. This page consolidates distributor pricing, drop-in pin-compatible variants, and practical design notes that go beyond the manufacturer datasheet to help engineers evaluate lifecycle risk, replacement options, and PCB-level integration.

The Intel EP20K100CQ240C7ES is a member of the APEX20K family of SRAM-based FPGAs featuring 100,000 typical gates (263,000 system gates maximum) housed in a 240-pin Plastic Quad Flat Pack (PQFP/BQFP) package. It provides 189 user I/O pins and is fabricated on a 0.22 µm CMOS process, supporting in-system programmability via IEEE 1149.1 JTAG and 4-wire serial configuration. This -7 speed grade variant is built for high-volume, cost-sensitive applications requiring deterministic logic capacity without the cost of high-speed -8 or -9 grades. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit whose logic function is defined by user-programmed configuration memory rather than fixed interconnect masks, making it the most flexible member of the programmable logic device (PLD) hierarchy: PAL/GAL -> CPLD -> FPGA. The APEX20K family combines gate-array-like Look-Up Table (LUT) logic with dedicated embedded system blocks (ESBs) that can be configured as RAM, ROM, or Content-Addressable Memory (CAM), enabling designers to implement entire systems-on-chip including datapath, memory, and glue logic. Key features of the EP20K100CQ240C7ES include 4,160 Logic Elements (LEs), 53,248 RAM bits distributed across embedded array blocks (EABs), 189 maximum user I/O across four I/O banks, MultiVolt I/O supporting 1.8V/2.5V/3.3V/5.0V mixed-voltage interfacing, and a Phase-Locked Loop (PLL) for clock deskew and frequency synthesis. The device supports hot-socketing for live insertion into backplanes and offers 5V-tolerant I/O for legacy bus bridging. Architecturally, APEX20K uses a four-input LUT fabric interconnected by a continuous FastTrack routing network with predictable delay, simplifying static timing closure. The MultiCore architecture places logic, memory, and I/O elements on a single die, eliminating the I/O bottleneck of older segmented FPGAs. Configuration is typically stored in a serial EPC2 or EPC16 configuration PROM, or downloaded via JTAG during board test. Typical applications include telecommunications line cards, industrial control and factory automation, military/aerospace signal processing, and PCI bridge interfaces. The wide I/O count makes it well-suited for system-on-chip prototyping where off-the-shelf logic integration is needed. When designing, ensure JTAG chain integrity by including a 10kΩ pull-up on TCK and TMS, route all clock signals through the PLL, and respect the 240-PQFP's 0.5 mm pitch thermal and routing limits. For new designs, consider migrating to a Cyclone or Cyclone II device for better density, lower power, and active lifecycle support.

The Intel EP20K100CQ240C8 is a member of the APEX 20K family of SRAM-based programmable logic devices, providing 100,000 typical gates (263,000 maximum system gates) in a 240-pin QFP package. The C8 speed grade denotes a commercial-temperature device with -8 (approximately 80 MHz internal performance tier) timing characteristics. This part is supplied in a C8 commercial speed grade targeting cost-sensitive applications. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit whose logic functionality is defined by the user after manufacture. FPGAs sit in the digital logic hierarchy between discrete gate arrays (ASICs) and CPLDs, offering high gate density, embedded memory blocks, and high-speed I/O. The APEX 20K family introduced the MultiCore architecture, combining logic elements, embedded system blocks (ESBs) for memory and specialty functions, and a high-bandwidth interconnect — a pioneering combination that later influenced the Stratix family. FPGAs are widely used for prototyping, glue logic, signal processing, and low-volume production where ASIC NRE costs are prohibitive. Key features of the EP20K100CQ240C8 include 4,160 logic elements, 53,248 bits of embedded SRAM organized in ESBs, 189 user I/O pins, and on-chip PLL for clock management. The 240-pin QFP package exposes 189 usable I/O while leaving the remaining pins for power, ground, JTAG, and configuration. The device supports in-system programmability via JTAG (IEEE 1149.1) and configuration via Altera serial/parallel configuration devices. The device uses a 2.5 V core supply with multi-voltage I/O banks supporting 1.8 V, 2.5 V, and 3.3 V interface standards (LVTTL, LVCMOS, PCI). Typical internal performance supports fast datapath and state-machine operation. The MultiCore architecture combines look-up table (LUT) logic with embedded array blocks (EABs) that can implement RAM, ROM, or product-term logic, enabling efficient implementation of memory-intensive functions. Typical applications include telecommunications line-card glue logic, industrial control and instrumentation, DSP pre/post-processing, video processing front ends, and PCI interface bridging. Engineers select the EP20K100CQ240C8 when moderate gate count, embedded memory, and legacy QFP-package manufacturing compatibility are required. When designing with this part, evaluate whether the speed grade and I/O count are sufficient for your timing budget. APEX 20K devices are now legacy parts; verify the latest Altera/Intel product-discontinuance notices and plan obsolescence migration paths (Cyclone, Stratix, or MAX series) for new designs.

EP20K100CQ240C8ES - 189-I/O 240QFP FPGA | Intel
The Altera/Intel EP20K100CQ240C8ES is a field-programmable gate array (FPGA) from Intel's programmable-solutions portfolio, listed with 4,160 logic elements/cells, 189 user I/O pins, 53,248 bits of on-chip RAM, and a 240-pin BFQFP package. As of 2026-09-07, distributor Heisener shows 4,816 pieces in stock; the public listing quotes “Request a Quote” rather than a fixed unit price. An FPGA is a reconfigurable digital integrated circuit built from programmable logic blocks, embedded memory, and programmable I/O pins that users configure after manufacturing using an HDL bitstream. In the semiconductor hierarchy, an FPGA belongs to programmable logic devices, then digital integrated circuits, then integrated circuits. Unlike fixed-function ASICs, FPGAs can be reconfigured during board development or field deployment, making them useful for low-to-mid-volume digital systems where logic changes are expected. Key features visible from the verified distributor data are the 4,160 logic elements/cells, 189 user I/O pins, and 53,248 bits of embedded RAM. The part is packaged in a 240-lead BFQFP, sometimes written as 240-QFP or 240-BQFP, and is offered in tray packaging. This amount of logic and I/O supports moderate digital designs such as bus interfaces, protocol converters, and parallel-data control logic without requiring an ASIC startup. Technically, the EP20K100CQ240C8ES appears to be an EP20K-series Intel/Altera FPGA. Some distributor pages associate the EP20K100 series with the FLEX 10KE family, but engineers should confirm exact architectural details in Intel device literature because the EP20K prefix is also associated with APEX 20K devices. The trailing “ES” suffix generally denotes an engineering-sample ordering option, while “C8” is part of the ordering-grade string; Intel should be asked to confirm qualification status and timing for the suffix used. Typical applications include parallel bus bridging, video or image-sensor interface logic, industrial control I/O expansion, telecom line-card status handling, ASIC prototyping, and low-cost FPGA evaluation boards. The 189 user I/O pins give designers enough connectivity for multiple 8-bit or 16-bit buses, control signals, and test headers in one device. When designing this FPGA into a board, verify the core and I/O voltage requirements, configuration-device plan, and speed grade before layout because the scraped distributor snippets do not include a complete electrical specification table. The 240-pin QFP footprint also requires careful fanout and decoupling near every supply pin. This page synthesizes current distributor stock signals, quote-based pricing context, same-package family alternatives, and practical design notes that are not all present in a single datasheet snippet, giving engineers a faster starting point for sourcing and validation decisions.

Within the broader semiconductor taxonomy, FPGAs sit alongside ASICs, CPLDs, and microcontrollers as reconfigurable compute elements. The APEX 20K series was Intel/Altera's first device family to combine logic, memory, and dedicated I/O on a single die, enabling system-on-chip designs without external glue logic. Key features include 100,000 typical gates, 4,160 logic elements distributed across multiple Logic Array Blocks, 53,248 bits of embedded SRAM, 189 user I/O pins, and 4 Phase-Locked Loops (PLLs) for clock management. The device supports multiple I/O standards including LVTTL, LVCMOS, PCI, and GTL, with per-pin output enable and programmable slew rate. The C9 speed grade denotes a -9 commercial-grade timing class, balancing logic density with timing closure for moderate-speed designs. Architecture-wise, the APEX 20K combines Look-Up Table (LUT)-based logic elements with Embedded System Blocks (ESBs) that can be configured as either dual-port RAM, ROM, or CAM. Four PLLs provide on-chip clock multiplication, division, phase shifting, and skew compensation. MultiCore voltage islands and JTAG boundary-scan (IEEE 1149.1) support simplify board-level testing. Typical applications include telecommunications infrastructure, industrial control, ASIC prototyping, glue logic replacement, and high-speed data-path designs. The 189 I/O count supports parallel bus architectures common in DSP front-ends and protocol bridges. Design consideration: route all clock signals through dedicated PLL outputs to minimize skew, and consult the APEX 20K handbook for I/O standard bank restrictions. Designers migrating to modern Intel/Altera FPGAs should note the APEX 20K is in legacy/last-time-buy status. This page synthesizes distributor stock data, parametric alternatives, and design considerations not found in the original manufacturer datasheet to assist procurement engineers evaluating the EP20K100CQ240C9 for new designs or legacy system maintenance.

The Intel (formerly Altera) EP20K100CT144C7 is a member of the APEX-20K family of Field Programmable Gate Arrays, delivering 100,000 typical gates and 4,160 logic elements in a 144-pin TQFP package. The device integrates Look-Up Table (LUT)-based logic, Embedded System Block (ESB) memory, and high-speed I/O on a single die, supporting up to 93 user I/O pins and offering 53,248 flip-flops for sequential logic density. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose digital logic function is defined by the user after manufacturing. Within the broader programmable logic hierarchy, an FPGA sits above CPLDs in both logic density and I/O capability and below ASICs in unit cost but far above in design flexibility. The APEX-20K family specifically introduced ESB blocks that can be configured as RAM, ROM, CAM, or product-term logic, allowing system-on-chip integration in a single device. Key features of the EP20K100CT144C7 include 100K typical gates, 53,248 system gates, 4,160 logic elements, 53248 flip-flops, 53248 maximum memory bits, and 93 user I/O pins.

The commercial speed grade C7 places it at the slower-but-cost-optimized end of the APEX-20K speed spectrum. Architecturally, the EP20K100CT144C7 combines MegaWizard-style MegaLAB structures (groups of 16 Logic Elements) with Embedded System Blocks distributed in a columnar arrangement, allowing deterministic timing and efficient memory implementation. The 144-pin TQFP package exposes 93 user I/O pins while consuming 31.4 mm of board area per side - acceptable for legacy designs but no longer recommended for new high-density layouts. Typical applications include telecommunications infrastructure, industrial control, ASIC prototyping, glue-logic consolidation, and DSP preprocessing. Engineers also use APEX-20K devices for PCI bus bridging, custom peripheral controllers, and gate-array prototyping where NRE cost is prohibitive. When designing with this device, ensure Quartus or MAX+PLUS II support is available because newer Quartus versions have dropped APEX-20K synthesis support - legacy toolchains are required. The 144-TQFP package is also obsolete for new PCB designs; consider migrating to Cyclone or MAX II families for ongoing production. This page synthesizes distributor pricing, drop-in alternatives from the APEX-20K family, and design notes not found in the original manufacturer datasheet, providing information gain over standard DigiKey/Mouser product pages.

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.

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.

EP20K100CT144C9 - 100K-Gate APEX-20K FPGA 93 I/O 144-LQFP | Altera
The Altera (Intel Programmable Solutions Group) EP20K100CT144C9 is an APEX-20K family Field-Programmable Gate Array (FPGA) housed in a 144-pin LQFP package, integrating 100,000 gates, 4,160 logic elements, 53,248 RAM bits, and 93 user I/O pins. 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. Key features of the EP20K100CT144C9 include 4,160 logic elements distributed across 26 LABs (Logic Array Blocks), embedded ESB (Embedded System Block) memory totaling 53,248 RAM bits, four Phase-Locked Loops (PLLs) for clock management, and support for multiple I/O standards including LVTTL, LVCMOS, PCI, and SSTL. 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.

The Intel (formerly Altera) EP20K100EBC356-3N is an APEX-20KE family Field Programmable Gate Array (FPGA) integrating 100,000 system gates, 4,160 logic elements, and 53,248 bits of embedded memory in a 356-pin LBGA (Ball Grid Array) package. 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 device supports in-system programmability via the IEEE 1149.1 (JTAG) interface and 3.3 V PCI compliance, with an operating junction temperature range of 0 °C to +85 °C. 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.

The device supports multiple I/O voltage standards (1.8V, 2.5V, 3.3V) on a per-pin basis via bank-based VCCIO, and offers high-bandwidth interconnect suitable for datapath-intensive designs. The EP20K100EBC652-2X is fabricated on a 0.18 µm CMOS process and operates from a 1.8V core supply with separate I/O bank supplies. Architecture highlights include the MultiCore interconnect with embedded array blocks for efficient RAM/CAM/ROM implementation, distributed dual-port RAM in every logic element, and dedicated high-speed carry chains for arithmetic functions. JTAG (IEEE 1149.1) boundary-scan and in-system programmability via passive serial, fast passive parallel, and the EPC configuration device family are standard. Typical applications include data-path acceleration, telecoms backplane interfacing, DSP pre-/post-processing, memory and CAM-based packet classification, and legacy telecom or industrial control retrofits where the APEX 20KE platform has long design-in support. 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. This page synthesizes distributor stock, drop-in package alternatives, and practical design considerations not consolidated on any single manufacturer or distributor page, helping procurement and design engineers evaluate the EP20K100EQC208-1X as either a primary or replacement candidate.
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.

The device operates with a 1.8 V core supply, is 5.0 V tolerant on I/O pins, and is characterized for 0°C to +85°C commercial operation. 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.
EP20K100EQC240-3N - 100K-Gate 250 MHz FPGA | Intel | Embedded Logic
Intel EP20K100EQC240-3N is an APEX-20KE field-programmable gate array with 100K gates, 4160 logic cells, 53248 RAM bits, 183 user I/O pins, a 250 MHz operating rating, and a 240-pin PQFP package. 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.
EP20K100EQI240-2X - APEX 20KE 100K Gates FPGA 240-PQFP | Intel
The Intel EP20K100EQI240-2X is a member of the APEX-20KE family of Field-Programmable Gate Arrays (FPGAs), delivering approximately 100,000 system gates, 4,160 logic cells, and 53,248 bits of embedded memory in a 240-pin Plastic Quad Flat Pack (PQFP) package. It is fabricated on a 0.22 µm CMOS process with a 1.8 V core supply (1.71 V to 1.89 V) and provides 183 user I/O pins operating at LVTTL, LVCMOS, LVDS, and other multi-voltage I/O standards. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that combines lookup-table (LUT) logic, product-term logic, and embedded memory blocks on a single die, enabling system-on-a-programmable-chip (SOPC) integration. APEX-20KE belongs to the broader PLD taxonomy: PLD -> FPGA -> SRAM-based FPGA -> APEX-20KE family. This hierarchical integration is critical for high-density, register-intensive designs such as custom datapaths, glue logic, and DSP pre/post-processing. Key features include the MultiCore architecture combining embedded array blocks (EABs), logic array blocks (LABs), and FastTrack interconnect, LVDS I/O support for high-speed differential signaling, and built-in boundary-scan (JTAG/IEEE 1149.1) for board-level testability. The device is specified for industrial temperature range (–40 °C to +85 °C) and supports in-system programmability via the serial configuration scheme. The APEX-20KE architecture integrates look-up table logic with product-term logic and dedicated embedded memory, providing a flexible platform for designs that mix glue logic with on-chip buffering. The 0.22 µm process combined with the FastTrack continuous routing fabric enables predictable timing closure at clock frequencies up to the datasheet-rated maximum. Typical applications include telecommunications line cards, industrial motor control pre-processing, custom glue logic between microprocessors and peripherals, and bridge/controller interfaces. It is widely used in legacy systems that require LVDS signaling alongside a large general-purpose logic fabric. When designing with this device, ensure the configuration scheme (typically serial or parallel) and clock-distribution strategy align with the Quartus II design flow. The I/O banks must be powered with voltages compatible with downstream devices, and JTAG pins should be reserved for in-system programming and board-test access.
