EP20K100CF324C7ES - 100K APEX-20K FPGA 4160 LEs 246 I/O | Intel

The Intel (formerly Altera) EP20K100CF324C7ES is a member of the APEX-20K programmable logic device family, integrating 263,000 system gates and 4,160 logic elements (LEs) in a 324-ball FineLine BGA package. It features 246 user I/O pins, 53,248 total RAM bits, and operates from a 2.375V to 2.625V core supply using Intel's advanced 0.22 micrometer CMOS process with embedded memory and MultiCore interconnect. The device belongs to the C7 speed grade family, optimized for low-power commercial-temperature designs. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement arbitrary digital logic. FPGAs sit within the programmable logic taxonomy: CPLD < FPGA (small, low-density, non-volatile) → FPGA (volatile SRAM-based, high-density, rich I/O) → SoC FPGA (integrated hard-core processors). The APEX-20K family sits at the high-density, embedded-memory-rich end of this hierarchy and was one of the first families to combine look-up table (LUT) logic with embedded system blocks (ESBs) that double as dual-port RAM, ROM, or content-addressable memory. This hypernym chain — FPGA → programmable logic → programmable logic device (PLD) → digital ASIC alternative — helps map the part to the broader silicon taxonomy. Key features include 16 embedded system blocks (ESBs) for distributed memory, four phase-locked loops (PLLs) for clock management, and support for LVTTL, LVCMOS, PCI, SSTL, and GTL+ I/O standards. The FineLine BGA-324 (19x19 mm) package supports high-density board layouts while exposing 246 I/O for high-bandwidth interfaces. The C7 speed grade is the slowest in the APEX-20K family, prioritizing low quiescent current and cost over raw clock frequency. The device uses a LUT-based logic fabric with embedded array blocks (EABs/ESBs) providing distributed synchronous RAM. Its MultiCore architecture connects the logic array, memory, and I/O elements via a continuous, predictable routing structure that simplifies timing closure. The 2.5V core, 5V-tolerant I/O cells, and dedicated clock networks let the part serve as a glue-less interface between microprocessors, memory buses, and high-speed parallel peripherals in mid-density systems. Typical applications include PCI bus bridges, custom peripheral controllers for industrial backplanes, telecom line-card glue logic, and DSP co-processing front-ends. The device is also commonly seen in legacy POS terminals, printers, and high-channel-count data acquisition front-ends where 246 I/O are valuable and a soft-core CPU can be synthesized in fabric. When designing with this part, verify I/O bank voltage compatibility before assigning mixed-voltage signals to the same bank. The SRAM-based configuration requires a configuration device (EPC) or microprocessor boot stream at every power-up, since in-design state is volatile. Long lead times are common because the APEX-20K family is now in obsolescence planning — order quantities, lifecycle status, and last-time-buy dates should be confirmed with the supply chain before committing to a new design.

EP20K100CF324C8 - APEX-20K FPGA 100K Gates 324-BGA | Intel

The Intel (formerly Altera) EP20K100CF324C8 is an APEX-20K family Field-Programmable Gate Array (FPGA) integrating 100,000 typical gates, 4,160 logic elements, and 53,248 RAM bits, housed in a 324-ball FineLine BGA package. It offers 246 maximum user I/O pins and operates at a core voltage of 1.8 V typical, fabricated on a 0.18 µm CMOS process. The 'C8' speed grade places it in the commercial temperature range with an 8-pin speed delay specification, suitable for cost-sensitive, moderate-performance designs. What is a FPGA? A Field-Programmable Gate Array is a reconfigurable semiconductor device that contains an array of programmable logic blocks, interconnects, and I/O cells, all controlled by on-chip SRAM configuration memory. FPGAs sit in the programmable logic hierarchy between ASICs (custom-designed, high-NRE) and CPLDs (smaller, non-volatile), enabling rapid prototyping and mid-volume production without mask charges. The APEX-20K family introduced embedded memory blocks (ESBs) and a MultiCore architecture combining look-up tables, product-term logic, and dual-port RAM in a single fabric. Key features of the EP20K100CF324C8 include 4,160 logic elements (LEs), 26 embedded system blocks (ESBs) totaling 53,248 RAM bits, support for LVCMOS, LVTTL, SSTL, and HSTL I/O standards, and in-system programmability via the IEEE 1149.1 JTAG interface. The 324-FBGA package provides a 1.0 mm ball pitch, balancing board density and manufacturability for mainstream designs. The device also supports Altera's Quartus II design software (legacy versions recommended for this older family), with bitstream configuration via serial or parallel modes. Architecture-wise, the APEX-20K combines a Logic Array Block (LAB) fabric with embedded memory and PLLs, allowing designers to implement glue logic, state machines, FIFO buffers, and simple DSP functions in a single chip. The 100K-gate density targets applications like telecom interface cards, industrial control bridges, and protocol converters where ASIC NRE is unjustified but discrete logic is too bulky. Typical applications include telecommunications line cards, industrial automation controllers, networking bridges, PCI interface glue logic, and legacy system upgrades that require drop-in replacement of older Altera APEX designs. The wide I/O count (246) supports many parallel bus interfaces simultaneously. When designing with the EP20K100CF324C8, verify Quartus II legacy support before committing to the device, since this family predates modern Intel Quartus Prime releases. Plan for 1.8 V core supply decoupling and configure I/O banks to match the 3.3 V or 2.5 V logic levels of surrounding components. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical legacy-design notes not found in the original manufacturer datasheet.

EP20K100CF324C8ES - APEX 20K FPGA, 100K Gates, 324-FBGA | Intel

The Intel (formerly Altera) EP20K100CF324C8ES is a member of the APEX 20K family of FPGAs, integrating 100,000 typical gates (263,000 maximum system gates) into a 324-ball FineLine BGA package. It combines a Look-Up Table (LUT) fabric with embedded array blocks (EABs) for high-density logic and on-chip memory, supporting up to 4,160 logic elements and 246 user I/O pins. The 'C8' speed grade is optimized for commercial-temperature operation while the 'ES' suffix indicates an engineering sample. An FPGA (Field-Programmable Gate Array) is a reconfigurable semiconductor that belongs to the broader category of programmable logic devices (PLDs) within the integrated circuit (IC) taxonomy: FPGA -> PLD -> logic IC -> integrated circuit. APEX 20K devices were among the first to merge LUT-based logic with embedded memory blocks (EABs), allowing designers to implement wide datapaths, FIFOs, and multiplier functions without external SRAM. Key features of the EP20K100CF324C8ES include 4,160 logic elements, 26 EABs providing up to 53,248 RAM bits, 246 maximum user I/O pins, and multi-voltage I/O support (1.8 V, 2.5 V, 3.3 V, 5.0 V) through dedicated bank reference pins. It uses SRAM-based configuration loaded from a serial PROM or via JTAG, and integrates four Phase-Locked Loops (PLLs) for clock multiplication, division, and phase shifting across the device. Architecturally, the APEX 20K family employs a MultiCore architecture that ties MegaLAB structures together via a FastTrack continuous routing network. This delivers high predictable performance for synchronous designs, with tpd (pin-to-pin) and fmax figures characteristic of the C8 speed grade suitable for 80–100 MHz internal operation in typical datapath applications. Typical applications include telecommunications line cards, glue-logic replacement, high-speed DSP co-processing, industrial control and instrumentation backplanes, and legacy design maintenance for products shipped in the late 1990s and early 2000s. The large 246-I/O count makes the 324-FBGA package appropriate for parallel bus bridging applications. When designing with this device, ensure your configuration scheme (EPC16/EPC8 serial PROM or JTAG) matches the board layout. Because the APEX 20K family is mature and approaching end-of-life, confirm long-term availability before starting new production designs; consider Cyclone or MAX series for new projects. This page consolidates distributor pricing, same-brand drop-in alternatives within the EP20K100 family, and practical design notes that go beyond the manufacturer's datasheet summary, including cross-brand note that no third-party drop-in exists in the same 324-FBGA footprint.

EP20K100CF324C9

EP20K100CF324C9 - APEX II FPGA 100K LE, 246 I/O, 324-FBGA | Intel

The Intel EP20K100CF324C9 is a member of the APEX II family of SRAM-based FPGAs, integrating 100,000 typical gates (logic elements) with 246 user I/O pins in a 324-ball FineLine BGA package. The device combines look-up table (LUT)-based logic with embedded system blocks, enabling designers to implement complex glue logic, on-chip bus interfaces, and DSP-style datapaths on a single programmable device. Speed grade -9 (C9) places this variant in the higher-performance bin within the APEX II family. A field programmable gate array (FPGA) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement arbitrary digital logic. The APEX II architecture extends the FPGA concept by combining fine-grained logic elements with dedicated embedded system blocks (ESBs) for memory and arithmetic functions, occupying a position in the hierarchy between raw gate arrays and structured ASICs. Compared to mask-programmed gate arrays, FPGAs offer zero NRE cost and instant prototyping, at the expense of die area, static power, and per-unit cost. Key features of the EP20K100CF324C9 include 100,000 typical gates, 4,160 logic elements, and 246 maximum user I/O pins. The LUT-based logic fabric is paired with embedded array blocks, allowing distributed and block RAM functions alongside general-purpose logic. The device supports in-system configuration via the IEEE 1149.1 JTAG interface and supports Altera (now Intel) Quartus development flows for synthesis, place-and-route, and timing closure. The FineLine BGA-324 package supports high I/O density for parallel buses and memory interfaces. The architecture combines a MultiCore interconnect with row-and-column-based logic and embedded array blocks. Each logic element contains a 4-input LUT, a programmable register, and dedicated carry-chain logic for fast arithmetic. The embedded system blocks can be configured as dual-port RAM, ROM, or content-addressable memory, enabling efficient implementation of FIFOs, lookup tables, and small state machines directly in silicon without consuming general logic. Typical applications for the EP20K100CF324C9 include telecommunications line cards, networking switches and routers, industrial control and instrumentation, prototyping bridges between microprocessors and ASICs, and legacy designs that were originally migrated from the APEX 20K family into the APEX II family. The device is also widely used in telecommunications equipment where the 246 I/O count and embedded memory blocks simplify glue-logic and protocol-processing tasks. When designing with this device, plan for the 1.8 V core and 3.3 V/2.5 V I/O supply rails and ensure PCB layout supports the FineLine BGA escape. Verify timing closure in Quartus at the chosen speed grade -9 before committing to layout, and budget for configuration PROM or JTAG-based in-system programming. Static power and thermal dissipation are modest but should still be modeled in dense designs.

EP20K100CQ208C7 - APEX20K FPGA 100K Gates 159 I/O 208QFP | Intel

The Intel (formerly Altera) EP20K100CQ208C7 is a member of the APEX20K family of SRAM-based FPGAs delivering 100,000 typical gates in a 208-pin Plastic Quad Flat Pack (PQFP/QFP) package. The device integrates 4,160 logic elements, 53,248 RAM bits, and 159 user I/O pins, supporting LVTTL, LVCMOS, and PCI I/O standards for flexible system integration. Key specifications include a core voltage of 1.8V, a maximum operating frequency of 180 MHz, and on-chip PLL support for clock management. The 'C7' speed grade indicates a 7 ns pin-to-pin logic delay, while the 'C' suffix denotes the commercial temperature range of 0C to +85C. The 208QFP package provides a perimeter I/O architecture ideal for through-hole-style PCB assembly or socketed designs. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, allowing hardware designers to implement custom digital circuits after manufacturing. FPGAs sit within the broader hierarchy of programmable logic devices -> logic ICs -> integrated circuits -> semiconductors. The APEX20K family pioneered the multi-core architecture (Logic Array Blocks + Embedded System Blocks) that later Stratix and Cyclone families refined. Architecturally, the EP20K100CQ208C7 combines four Logic Array Blocks (LABs) interconnected via the FastTrack Interconnect routing fabric, with embedded system blocks providing True Dual-Port RAM and Content-Addressable Memory (CAM) support. The 1.8V core reduces dynamic power consumption compared to the older 5V FLEX10K family, while the LVTTL/LVCMOS I/O standards enable direct interfacing with modern microprocessors, DSPs, and memory devices without external level shifters. Typical applications include legacy telecommunications backplane glue logic, industrial control systems, PCI bus interface bridges, and ASIC prototyping. The 159 user I/O pins comfortably support 32-bit processor bus emulation and multi-channel DMA controllers in cost-sensitive embedded designs. When designing with the EP20K100CQ208C7, ensure the Quartus II design tool (or MAX+PLUS II for legacy flows) is configured for the APEX20K device family and the 208-pin QFP package. The PQFP package's long lead frame requires careful signal integrity analysis for high-speed signals above 66 MHz.

EP20K100CQ208C7ES

EP20K100CQ208C7ES - 100K Gate APEX-20KE FPGA, 208-PQFP | Intel

The Intel EP20K100CQ208C7ES is a 100,000-gate APEX-20KE Field Programmable Gate Array (FPGA) housed in a 208-pin Power Quad Flat Pack (PQFP / BFQFP) package. The device integrates 4,160 logic elements, 53,248 typical gates, and 32,768 bits of embedded RAM across 159 user I/O pins, making it a flexible platform for medium-density programmable logic designs. The 'C' speed grade designates a commercial 0.7 ns pin-to-pin logic delay tier for the APEX-20KE family. A Field Programmable Gate Array (FPGA) is a reprogrammable semiconductor device containing an array of configurable logic blocks (CLBs), embedded memory, and programmable routing interconnects that engineers can tailor to a custom digital function after manufacture. FPGAs occupy a specific tier in the programmable logic hierarchy: below them sit CPLDs (Complex Programmable Logic Devices) for glue logic, and above them sit ASICs and structured ASSPs for high-volume fixed-function designs. The APEX-20KE family targets multi-MHz datapath, bus-interface, and DSP-front-end designs where neither a CPLD's limited density nor an ASIC's NRE cost is acceptable. Key features of the EP20K100CQ208C7ES include 4,160 logic elements (LEs), 32,768 bits of embedded SRAM, up to 159 user I/O pins, and a true MultiVolt I/O interface that supports 2.5V/3.3V/5V mixed-voltage operation. The architecture combines look-up table (LUT)-based logic with dedicated carry chains, embedded memory blocks, and a four-phase PLL clock network. Embedded signal-processing capability and dedicated FastTrack interconnect routing allow efficient implementation of 16-bit multipliers, FIFOs, and wide datapath functions. Typical applications include telecommunications line-card glue logic, industrial machine-control interface bridging, flat-panel display timing controllers, PCI/ISA bus peripherals, and legacy ASIC prototype replacements. The BFQFP-208 footprint also makes it usable as a drop-in for existing APEX-20K / APEX-20KE designs requiring a logic upgrade. When designing with this part, ensure your I/O assignments respect the bank voltage groupings and that configuration is provided via the supported passive serial, parallel, or JTAG modes. The 208-pin PQFP package has substantial thermal mass but limited PCB-side cooling - keep sustained toggle rates below the package's recommended 1.0W dissipation budget at commercial ambient.

EP20K100CQ208C8 - APEX20KE FPGA 100K Gates 208-PQFP | Altera

The Altera EP20K100CQ208C8 is a member of the APEX 20KE family of high-density SRAM-based FPGAs, delivering 100,000 typical gates and 4,160 logic elements in a 208-pin Plastic Quad Flat Pack (PQFP) package. The device integrates an array of Logic Array Blocks (LABs), Enhanced Logic Elements (ELEs), and a MultiCore interconnect, providing 53,248 bits of embedded system blocks (ESB) for RAM or ROM functions and 100,000 bits of dedicated RAM. Speed grade C8 places the part in the mid-speed bin for industrial and commercial applications. An FPGA (Field-Programmable Gate Array) is a reconfigurable semiconductor device composed of programmable logic blocks, interconnect, and I/O cells that engineers can configure after manufacturing to implement custom digital functions. APEX 20KE FPGAs sit in the mid-to-high density tier of the Altera product taxonomy: gate array -> programmable logic -> FPGA -> complex programmable logic device (CPLD) family neighbor. They bridge the gap between simpler CPLDs and high-end Stratix-class FPGAs, supporting both glue-logic replacement and moderate DSP/data-path workloads. Key features include 208 user I/O pins, 4 PLLs for clock management, multi-voltage I/O support (1.8V, 2.5V, 3.3V, 5.0V), 3.3V PCI-compliant operation, and JTAG-based in-system programmability via ByteBlaster or Master/Slave serial modes. The C8 speed grade specifies a 1.5ns pin-to-pin delay on standard I/O. The APEX 20KE architecture separates logic, memory, and interconnect into independent MultiCore domains, allowing concurrent operation of up to four system blocks per LAB cluster. Typical applications include telecommunications line cards, industrial control backplanes, PCI bridge designs, and legacy system upgrades for designs originally prototyped on APEX 20K devices. Designers transitioning to the -KE variant gain additional ESB memory and lower static power compared with the APEX 20K baseline. When designing with the EP20K100CQ208C8, observe the 1.25W typical power dissipation at full utilization and provide a minimum of 200 LFM airflow for sustained operation above 70% utilization. The PQFP-208 package requires an exposed-pad-style thermal footprint strategy; copper pours should extend at least 1 square inch beneath the package for adequate heat spreading.

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.

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.

EP20K100CQ240C7 - APEX-20K FPGA, 100K Gates, 240-Pin QFP | Altera

The Altera (now Intel PSG) EP20K100CQ240C7 is a member of the APEX-20K family of Field Programmable Gate Array (FPGA) devices, integrating 100,000 system gates with 53,248 logic elements and 4,160 dedicated RAM bits in a 240-pin Plastic Quad Flat Pack (BFQFP) package. 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.

EP20K100CQ240C7ES - 100K Gates APEX20K FPGA, 189 I/O, 240-PQFP | Intel

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.

EP20K100CQ240C8 - APEX 20K FPGA, 100K Gates, 240-QFP | Intel

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

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.

The Intel EP20K100CQ240C9 is a member of the APEX 20K family of high-density SRAM-based FPGAs, integrating 100,000 typical gates, 4,160 logic elements, and 53,248 RAM bits in a 240-pin BQFP (QFP-240) package with 189 user I/O pins. It operates across a commercial temperature range and is built on a 0.22 µm CMOS SRAM process with in-system programmability via Intel (formerly Altera) Quartus and MAX+PLUS II design software. An FPGA (Field Programmable Gate Array) is a programmable logic device that allows engineers to implement custom digital circuits through configurable logic blocks (LABs), embedded memory arrays (ESBs), and programmable interconnect. 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.

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 device operates from a 1.8V core supply with 3.3V multi-voltage I/O support, and is fabricated on a 0.18-micrometer CMOS process. 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.

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.

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.

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.

The Intel EP20K100CT144C8ES is a high-density APEX-20K Field Programmable Gate Array (FPGA) housed in a 144-pin LQFP (Low-profile Quad Flat Pack) package. 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.

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 integrates logic elements (LEs), embedded system blocks (ESBs) for memory and CAM, and a MultiCore architecture that combines look-up table (LUT) logic with embedded array blocks on a single die. The "EBC652" suffix denotes the 652-ball BGA package, the "-2X" speed grade designates a faster commercial speed grade, and the device supports advanced I/O standards such as LVDS, LVTTL, LVCMOS, and PCI. An APEX 20KE device is a SRAM-based programmable logic device (PLD) belonging to the FPGA (Field Programmable Gate Array) category, which in turn sits within the broader taxonomy of programmable logic devices -> logic ICs -> integrated circuits -> semiconductors. The APEX 20KE family extends the APEX 20K family up to 1.5 million gates and adds enhanced I/O standard support, CAM, additional global clocks, and improved ClockLock clock circuitry compared with the original APEX 20K line. Key features of the EP20K100EBC652-2X include up to 4,160 logic elements, embedded system blocks providing up to 53,248 RAM bits or CAM, fast on-chip interconnect with direct connections and FastTrack routing, and up to four Delay-Locked Loop (DLL) ClockLock circuits for precise clock de-skew.

EP20K100EFC144-1 - APEX 20KE FPGA, 100K Gates, 144-FBGA | Intel
EP20K100EFC144-1

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.

EP20K100EFC324-1N

EP20K100EFC324-1N - APEX-20KE FPGA 100K Gates 246 I/O | Altera

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
EP20K100EFC324-2X

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.
