EP20K200RC208-3 - APEX 20K 200K Gates FPGA, 208-RQFP | Intel
The Intel (formerly Altera) EP20K200RC208-3 is a member of the APEX 20K family of Field Programmable Gate Arrays (FPGAs) delivering 200,000 system gates in a 208-pin RQFP (Exposed Pad) package. The device integrates 8,320 logic elements and 106,496 bits of embedded memory across the industry's first MultiCore architecture combining look-up table (LUT) logic, product-term logic, and embedded memory blocks on a single die. Fabricated on a 0.22 µm CMOS process, the APEX 20K family supports 1.8 V core operation with LVDS-compatible I/O and a system-level operating frequency up to 167 MHz. What is an FPGA? A Field Programmable Gate Array is a reconfigurable semiconductor device that allows hardware logic to be programmed after manufacture. The APEX 20K family pioneered system-on-a-programmable-chip (SOPC) integration, embedding up to 1.6 Mbits of RAM directly into the fabric alongside logic and product-term resources, eliminating external SRAM in many designs. This architecture places the EP20K200RC208-3 in a hierarchy of: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit. The MultiCore architecture combines three specialized structures: LUT-based logic for register-intensive functions, embedded array blocks (EABs) implementing memory or product-term logic, and a high-bandwidth interconnect network. The EP20K200RC208-3 supports up to 144 user I/O pins via LVDS signaling, with four phase-locked loops (PLLs) for clock management. The device supports hot-socketing, in-system programmability via IEEE 1149.1 JTAG, and operates across the industrial temperature range from -40°C to +85°C. Typical applications include high-speed telecommunications interfaces, PCI bridge logic, DSP co-processing, and custom parallel bus controllers where the embedded memory eliminates the need for external SRAM. The 208-RQFP package provides a thermally enhanced footprint with an exposed pad for thermal dissipation, and the -3 speed grade places this part in the mid-range of APEX 20K performance options. When designing with the EP20K200RC208-3, engineers should verify that the Quartus development toolchain (versions prior to 9.1) supports the device and that PCB thermal vias are placed under the exposed pad to maintain junction temperature under full I/O loading. Note that the APEX 20K family has reached end-of-life; consider Cyclone II or Cyclone III for new designs, and use this part only for maintenance of existing systems. This page synthesizes distributor availability, parametric alternatives, and design considerations specific to the APEX 20K family that are not aggregated on any single manufacturer or distributor page, helping engineers evaluate lifecycle risk and replacement strategies.
EP20K200RC208-3N - APEX 20K FPGA 200K Gates 8320 Cells 167MHz | Altera
The Altera (now Intel) EP20K200RC208-3N is a member of the APEX-20K family of programmable logic devices, integrating 200,000 system gates, 8,320 logic elements (cells), and 106,496 bits of embedded memory into a single MultiCore architecture die. Housed in a 208-pin RQFP / BFQFP package with exposed thermal pad, this device combines look-up table (LUT) logic, product-term logic, and embedded memory blocks on one silicon substrate, embodying the system-on-a-programmable-chip (SOPC) concept that defined late-1990s high-density PLD design. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device whose interconnect and logic resources are configured by the customer after manufacture using a hardware description language (HDL) and a configuration bitstream. FPGAs sit at the top of the programmable logic hierarchy - above simple PLDs, CPLDs, and structured ASICs - and are widely used to implement glue logic, custom processor peripherals, DSP pipelines, and prototype ASICs. The APEX-20K family in particular pioneered the integration of dedicated memory blocks (ESBs) with general-purpose LUT logic, allowing system-on-chip functionality before true SoC ASICs were widely available. Key features include 144 user I/O pins, 4 dedicated inputs, a maximum operating frequency of 167 MHz, CMOS process technology at 0.22 micrometer geometry, and a 2.5V core supply with LVDS-compatible I/O capability. The 'N' suffix indicates an industrial temperature grade of 0C to +85C, while the '3' speed grade places this part in a moderate performance bin suitable for designs that do not require the highest possible internal clock rate. From an architectural standpoint, the EP20K200RC208-3N uses Altera's MultiCore architecture, which interleaves logic array blocks (LABs), embedded system blocks (ESBs) for memory, and FastTrack interconnect. This design lets the device serve both register-intensive datapath logic and high-density memory functions such as FIFOs and dual-port RAMs without external SRAM. The exposed thermal pad on the BFQFP package aids heat extraction for sustained high-utilization designs. Typical applications include telecommunications line cards, industrial control and instrumentation, glue logic for DSP boards, custom peripheral controllers, and ASIC prototyping. Designers select this device when they need high gate density plus on-chip memory in a proven, mature silicon process with abundant Quartus II design-tool support. When designing with the EP20K200RC208-3N, ensure the 208-pin BFQFP land pattern includes the exposed thermal pad soldered to a copper pour to meet thermal and electrical grounding requirements. Quartus II (legacy MAX+PLUS II for older designs) is the supported development environment; configuration bitstreams are loaded via the ByteBlaster or compatible JTAG programmer. This page synthesizes distributor stock levels, verified drop-in alternatives, and practical design notes that complement the official APEX-20K datasheet family specification.
EP20K200RC208-3V FPGA - APEX-20K 8320 LE, 144 I/O | Altera
The Altera EP20K200RC208-3V is an APEX-20K family Field-Programmable Gate Array (FPGA) providing 8,320 logic elements, 106,496 RAM bits, 144 user I/O pins, and 200K typical gates in a 208-pin RQFP/BFQFP exposed-pad package. This 2.5V-core device operates from a 2.375V to 2.625V supply and is reported in distributor parametric listings with a maximum internal frequency of 167 MHz. It is designed for high-density glue logic, DSP datapaths, protocol bridging, and system-on-a-programmable-chip (SOPC) implementations. An FPGA is an integrated circuit whose logic fabric can be reconfigured after manufacturing using hardware description languages and a configuration bitstream. Unlike a fixed-function ASIC, an FPGA consists of programmable logic blocks, routing interconnect, and embedded memory that allow the same silicon to implement different digital systems. The APEX-20K family belongs to the broader class of programmable logic devices (PLDs), with architecture that bridges look-up table (LUT)-based FPGAs and CPLD-style product-term logic. The EP20K200RC208-3V uses a MultiCore architecture that combines LUT logic for register-intensive functions, product-term logic for combinatorial control, and embedded memory blocks. This lets one FPGA integrate finite-state machines, arithmetic datapaths, FIFOs, and small processor peripherals without multiple external devices. The 106,496 RAM bits are useful for packet buffers, coefficient tables, and dual-clock domain FIFOs, while 144 user I/O pins can connect to external memories, buses, and application-specific interfaces. Four-level hierarchical FastTrack interconnect provides predictable routing delays, which is important for meeting timing in medium-speed designs. The 0.22um CMOS process and 2.5V core make the device lower-power than older 5V/3.3V CPLDs while still supporting legacy I/O systems with appropriate level translation. The exposed thermal pad in the BFQFP/RQFP package improves heat transfer to the PCB when a solid ground/thermal plane is provided. Typical uses include telecom line-card control, industrial motion-control I/O, instrumentation logic, and SOPC evaluation boards. Designers often select this FPGA when they need to upgrade existing PLD/FPGA boards without altering the 208-pin RQFP footprint. Since the APEX-20K family is a mature product, the EP20K200RC208-3V is frequently sourced for legacy system life-extension and second-source programs through distributors such as Rochester Electronics. When designing with this part, provide separate clean supply rails for the 2.5V core, follow the configuration power-up sequence, and connect every unused I/O according to the recommended safe state to avoid floating inputs. The package exposed pad should be soldered to the PCB ground plane for thermal and electrical integrity. This page synthesizes distributor availability, same-package speed-grade alternatives, and practical design notes that are not all present in a single manufacturer datasheet, giving engineers a faster way to evaluate legacy FPGA replacements.
EP20K200RC240-1 - APEX 20K FPGA 200K Gates 8320 Cells | Intel
The Intel EP20K200RC240-1 is a member of the APEX 20K family of programmable logic devices (PLDs), the industry's first devices to deliver system-on-a-programmable-chip (SOPC) integration. Housed in a 240-pin RQFP (BFQFP with exposed pad) package, this device integrates 200,000 gates, 8,320 logic cells, and 106,496 bits of embedded memory using a 0.22 µm process at 2.5 V core, with up to 174 user I/O pins and a maximum internal frequency of 250 MHz. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells, all of which can be redefined by the designer after manufacturing. FPGAs sit in the broader hierarchy of programmable logic devices (PLDs), bridging the gap between fixed-function ASICs and software-defined processors. The APEX 20K family extends this further by combining LUT logic, product-term logic, and embedded memory on a single MultiCore architecture, eliminating the need for external companion chips in many designs. Key features of the EP20K200RC240-1 include its MultiCore architecture combining look-up table (LUT) logic, product-term logic, and embedded memory blocks, LVDS-capable I/O support, in-system programmability via SRAM configuration cells, and dedicated interfaces such as the FastTrack interconnect and a PLL-rich clock network. The exposed thermal pad on the 240-BFQFP package improves heat spreading for sustained high-utilization designs. Technically, the device is implemented on a 0.22 µm CMOS process, supports a 2.5 V core supply, and provides 8320 logic elements (LEs) and 106,496 RAM bits across four embedded array blocks (EABs). The LVDS I/O option (-1 suffix indicates the speed grade) supports low-voltage differential signaling, which is critical for reducing EMI in high-speed parallel buses between FPGAs and external memory or backplane transceivers. Typical applications include telecommunications infrastructure (SONET/SDH framer interfaces, ATM switching), high-speed data acquisition and DSP pre-processing, ASIC prototyping, and embedded control systems in industrial and military designs. The wide gate count makes it suitable for multi-channel signal conditioning pipelines. When designing with the EP20K200RC240-1, ensure the Quartus II toolchain (or MAX+PLUS II for legacy designs) is used for synthesis, place-and-route, and timing closure. Decoupling capacitors must be placed adjacent to every VCCINT/VCCIO pin pair, and the exposed pad must be soldered to a continuous ground plane for thermal performance and signal return paths. This page synthesizes distributor pricing for the EP20K200RC240-1, a curated list of same-package drop-in alternatives within the APEX 20K family, and practical PCB layout notes not consolidated in the original datasheet.
EP20K200RC240-2X - APEX-20K FPGA 8320 LE | Altera
The Altera EP20K200RC240-2X is an APEX-20K field-programmable gate array (FPGA) with 8,320 logic elements (LEs), 106,496 RAM bits, and 174 user I/Os, supplied in a 240-pin BFQFP (RQFP) package with exposed thermal pad. It is a legacy 2.5 V APEX-20K family device and is now commonly supported through aftermarket authorized channels such as Rochester Electronics on DigiKey Marketplace. An FPGA is a semiconductor device containing programmable logic blocks and programmable interconnect, allowing designers to configure the silicon for a specific digital function after manufacturing. In the hierarchy of programmable logic, an FPGA sits between CPLDs and ASICs: it provides more logic capacity than a CPLD and enables rapid design changes without the non-recurring engineering cost of a custom ASIC. The APEX-20K architecture was designed for system-on-a-programmable-chip integration, placing FPGA-like LUT logic, CPLD-like product-term logic, and embedded memory on one device. Key features of the EP20K200RC240-2X include 8320 logic elements, 174 user I/Os, 106496 bits of embedded RAM, and a 240-BFQFP RQFP package. According to FPGAkey part summary data, this device is built on a 0.22 micron process, operates with a 2.5 V core supply, and is rated with a 200 MHz maximum clock frequency. The 200K typical gate count and MultiCore architecture make it suitable for medium-density digital designs that benefit from both look-up-table logic and product-term logic. The APEX-20K MultiCore architecture integrates LUT-based logic for register-intensive functions, product-term logic for high-speed combinatorial functions, and embedded memory for FIFOs, dual-port RAM, and ROM. This flexibility allows communication systems and DSP pipelines to consolidate multiple PLDs or discrete memories into one FPGA. The 2.5 V core distinguishes this device from the later APEX-20KE family, which operates at 1.8 V and requires a different power delivery design. Typical applications include communication line cards, network infrastructure interfaces, DSP preprocessing, protocol bridging, and test equipment. The 174 I/O pins allow parallel buses and control signals to be connected directly to backplanes, ASICs, microprocessors, or other FPGAs. The embedded memory supports packet buffering and small FIFOs without external SRAM. When designing with this device, verify that the board supplies a clean 2.5 V VCCINT rail. Do not use EP20K200E-family devices as direct drop-ins for an existing 2.5 V design unless the PCB is also changed to supply 1.8 V. Because the part is obsolete for new designs, confirm device availability and lifetime support with the supplier before committing to a production release. This page synthesizes distributor listings, package and family context, practical substitution guidance, and design notes that go beyond the basic manufacturer datasheet. It is intended for engineers maintaining legacy APEX-20K systems, evaluating surplus stock, or looking for a pin-compatible RC240 speed-grade replacement.
EP20K200RC240-3 - APEX-20K FPGA, 200K Gates, 240-BFQFP | Intel / Altera
The Intel (formerly Altera) EP20K200RC240-3 is an APEX-20K series Field-Programmable Gate Array (FPGA) from the Apex 20KE Device Family, integrating 106,496 system gates and 8,320 logic elements into a 240-pin BFQFP (Plastic Quad Flat Pack) exposed-pad package. Speed grade -3 places it in the slower commercial-grade bin optimized for 1.8V LVDS-compatible I/O and low static power. The device features 174 user I/O pins, embedded MultiCore architecture combining look-up table (LUT) logic, product-term logic, and embedded memory blocks (ESBs). An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that the designer can program after manufacturing. FPGAs sit at the top of the programmable logic hierarchy: programmable logic device (PLD) -> complex programmable logic device (CPLD) -> FPGA. They are used to implement arbitrary digital logic, glue logic, signal processing pipelines, and full processor subsystems without fabricating a custom ASIC. The APEX-20K family was Altera's first SOPC (system-on-a-programmable-chip) platform, integrating look-up tables for register-intensive functions and product-term logic for arithmetic paths into a single fabric. Key features of the EP20K200RC240-3 include 174 maximum user I/O, 4 Embedded System Blocks (ESBs) supporting True Dual-Port RAM at up to 311 MHz in -3 speed grade, an internal MultiTrack interconnect for high-speed routing, and IEEE 1149.1 JTAG boundary-scan support. The 1.8V core (VCCINT) with 2.375V to 2.625V supply tolerance and 3.3V tolerant I/O make it well suited for mixed-voltage board designs. Typical applications span telecommunications line cards, industrial control, high-speed data processing, DSP co-processing, and legacy ASIC replacement. The wide I/O count and embedded RAM make it effective for bus-bridging, custom peripheral controllers, and parallel DSP pipelines. Designers should configure the device with Quartus II (legacy) or Max+Plus II to generate the configuration bitstream loaded into the on-chip SRAM cells. This page synthesizes distributor pricing, drop-in pin-compatible alternatives, and practical design notes not found in the manufacturer datasheet alone. Engineers comparing this part against modern Cyclone or Lattice alternatives should weigh the 1.8V core supply, BFQFP-240 footprint, and active Altera/Intel legacy support window.
EP20K200RC240-3N - APEX 20K FPGA 200K Gates 167MHz 240-RQFP | Intel
The Intel (formerly Altera) EP20K200RC240-3N is a member of the APEX 20K family of field-programmable gate arrays (FPGAs) fabricated on a 0.22 µm CMOS process, integrating approximately 200,000 system gates and 8,320 logic elements (LEs) in a 240-pin RQFP package with exposed pad. It supports a maximum internal clock frequency of 167 MHz and operates from a 2.5 V core supply. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit whose logic function is defined after manufacturing by the end user. FPGAs occupy a unique position in the integrated circuit taxonomy: programmable logic device (PLD) -> FPGA -> system-on-a-programmable-chip (SOPC). They are widely used as prototyping vehicles and as low-volume production alternatives to custom ASICs, providing high I/O count, embedded memory, and parallel processing capability unavailable in fixed-function microcontrollers or DSPs. Key features of the EP20K200RC240-3N include MultiCore architecture that integrates look-up table (LUT) logic, product-term logic, and embedded memory in a single device. The device exposes 174 user I/O pins, four dedicated inputs, and supports LVDS signaling in some APEX 20KE variants. Maximum propagation delay is rated at 3.6 ns through the I/O pad, and the device provides on-chip phase-locked loops (PLLs) and embedded system blocks (ESBs) for distributed dual-port RAM. The APEX 20K family introduced the MultiCore concept that combined fine-grained LUT logic with coarse-grained product-term logic, allowing designers to mix data-path and control logic efficiently. The -3N speed grade designates the standard-speed commercial-temperature grade with Pb-free (lead-free) packaging, suitable for designs that do not require the higher-performance -2 or -1 grades or the wider -I industrial temperature option. Typical applications include telecommunications line-card interfaces, custom DSP preprocessing blocks, industrial motor-control glue logic, prototyping bridges to ASICs, and high-speed data-acquisition front-ends where 174 user I/Os are required. The exposed pad on the 240-RQFP package aids thermal dissipation but is electrically bonded to ground. When designing with this device, account for its NRND status - it has not been recommended for new designs since the APEX 20K family was superseded by Cyclone, Stratix, and Arria families. New designs should target a Cyclone III/IV/10 LP or MAX V equivalent unless legacy compatibility is required. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
EP20K200RI240-2 - APEX 20K FPGA, 200K Gates | Altera
The Altera EP20K200RI240-2 is an APEX 20K family Field Programmable Gate Array (FPGA) with a system gate count of 200,000 gates, 8,320 logic cells, and a maximum internal frequency of 200 MHz, operating from a 2.5V core supply and housed in a 240-pin RQFP (RQFP-240) package. The suffix "RI240-2" indicates the industrial temperature grade variant in the RQFP-240 package with the -2 speed grade. An FPGA is an integrated circuit whose logic fabric can be programmed after manufacturing. Unlike fixed-function ASICs, FPGAs use configurable logic blocks, programmable interconnects, and embedded memory to implement digital circuits that can be updated in the field. In a system hierarchy, an FPGA belongs to programmable logic devices (PLDs), which in turn fall under integrated circuits and semiconductor devices. APEX 20K devices were among the first PLDs designed for system-on-a-programmable-chip (SOPC) integration, combining reconfigurable logic with embedded memory. Key features of the EP20K200RI240-2 include the MultiCore architecture, which integrates look-up table (LUT) logic, product-term logic, and embedded memory in one device. The 200,000 system gates and 8,320 logic cells provide substantial logic density for medium-complexity digital designs. The 200 MHz internal frequency is ideal for legacy telecom, data-path, mathematical, and digital signal processing (DSP) applications. The 2.5V core supply reduces power consumption compared to earlier 3.3V FPGA families, while the 240-pin RQFP package offers a practical balance between I/O count and board-level routability. Technically, the EP20K200RI240-2 leverages Altera's MultiCore architecture: LUT-based logic gives optimized performance for data-path and register-intensive functions, product-term logic handles wide combinatorial functions efficiently, and the embedded memory blocks support FIFOs, RAM, and ROM without consuming external components. The device was designed for SOPC integration, making it possible to combine processor cores, memory, and custom logic on a single programmable platform. Typical applications include legacy communications equipment, industrial control systems, video/imaging processing, and DSP front-ends where a mid-density FPGA with 200K gates and numerous parallel I/O channels is required. The 200 MHz performance is sufficient for bridged protocol conversion, UART/parallel interfaces, and custom state machines. Because the EP20K200RI240-2 is obsolete, design engineers should not start new board layouts using this device. Altera/Intel community guidance indicates there is no direct pin-compatible replacement in current product families; migration to Cyclone IV or Cyclone 10 requires PCB and power-supply changes. If prototype or legacy repair quantities are needed, the same-package commercial-temperature variants such as EP20K200RC240-3 can serve as PCB-compatible substitutes only within commercial temperature limits. This page synthesizes distributor availability, pricing references, same-family alternatives, and practical obsolescence guidance that are not all present in the original APEX 20K datasheet. Use it to make quick lifecycle, sourcing, and replacement decisions for legacy FPGA-based products.
EP20K200RI240-2V - APEX 20K FPGA, 200K Gates, 240 RQFP | Altera
The Altera EP20K200RI240-2V (now supported under Intel Programmable Solutions Group) is an APEX 20K family field-programmable gate array (FPGA) with 200,000 typical gates and 8,320 logic cells, manufactured in a 0.22 um CMOS process. It operates from a 2.5 V core supply and is supplied in a 240-pin RQFP (S-PQFP-G240) package with 174 user I/O lines and 4 dedicated inputs. The -2 suffix indicates the speed grade; the I prefix denotes industrial temperature screening. An FPGA is a semiconductor device containing programmable logic blocks and interconnect that can be configured after manufacturing to implement digital systems. In the APEX 20K architecture, look-up table (LUT) logic, product-term logic, and embedded memory are combined, so control logic, datapath functions, and memory resources can be integrated on a single programmable device. This places the part in the programmable logic hierarchy of FPGA -> programmable logic device -> semiconductor, between simple CPLDs and large contemporary FPGAs. Key features of the EP20K200RI240-2V are its 200K-gate capacity, 8,320 logic cells, 174 user I/O lines, 2.5/3.3 V I/O capability, and 0.22 um process. Distributor listings specify 200 MHz maximum clock speed for the family/order code, while Microchip USA records a 160 MHz figure for this package and temperature variant. The 240-pin 0.5 mm-pitch RQFP package supports surface-mount assembly and moderate-density board layouts. The architecture includes embedded memory blocks and MultiCore LUT-plus-product-term logic, enabling designs that blend state machines, arithmetic datapaths, and memory. The I/O supports LVTTL/LVCMOS-style interfaces at 2.5 V or 3.3 V, depending on the VCCIO bank setting. Because this is an industrial-suffix part, it is intended for environments requiring wider operating temperature range than commercial -C alternatives. Typical applications include legacy industrial controller repairs, telecom infrastructure glue logic, custom test equipment, and retrofit of APEX 20K-based boards where no direct pin-compatible newer FPGA exists. Its large I/O count and block memory make it suitable for bus interfacing, video capture preprocessing, and medium-density control functions. A key design consideration is that this is an obsolete part with no verified direct replacement in newer Intel/Altera families. Keep the 2.5 V core separate from the I/O supply, verify pin compatibility against the original datasheet before substituting a 240-RQFP sibling, and plan a last-time buy if production must continue. This page assembles distributor availability, package details, cross-reference caveats, and maintenance-oriented design guidance that are not all present in a single manufacturer datasheet, helping engineers keep legacy systems alive with verified parametric grounding.

The Altera (Intel) EP20K300EBC652-1 is an APEX 20KE-family Field Programmable Gate Array (FPGA) integrating 300,000 system gates with 11,520 logic elements (LEs) and 147,456 bits of embedded SRAM in a 652-ball BGA package. Built on a 1.8 V, 0.22 µm CMOS process, it operates from a 1.71 V to 1.89 V core supply and supports LVDS I/O, with a maximum internal clock frequency around 400 MHz per published device specifications. The 'E' suffix denotes the enhanced 1.8 V APEX 20KE family, while the 'BC652' code identifies the 652-pin BGA package. An APEX 20KE device is a system-on-a-programmable-chip (SOPC) platform that combines look-up table (LUT) logic, product-term logic, and embedded memory blocks in a MultiCore architecture. This hybrid structure places LUTs alongside product-term arrays, allowing the silicon to map both datapath-intensive and control-intensive logic efficiently while embedding 147 kbits of dual-port RAM for FIFO, register-file, and buffering functions without external memory. Architecturally, the APEX 20KE family sits between older FLEX 10K-era devices and the later Stratix/Arria families, offering a balance of density, on-chip memory, and I/O flexibility for programmable logic designs. Key features include 11,520 LEs, 147,456 bits of embedded RAM, 408 user I/O pins (ball map of the 652-BGA), LVDS-compatible I/O, and JTAG-based in-system programming via the ByteBlasterMV or MasterBlaster cable. The 652-BGA (45x45 mm) package exposes the full I/O count of the APEX 20KE family and supports an industrial operating range for telecom, networking, and DSP front-end applications. Typical applications include telecommunications line cards, networking switches and routers, DSP co-processing in baseband designs, high-speed data acquisition front ends, and industrial control systems. The combination of LVDS I/O, embedded RAM, and high logic density makes it suitable for glue-logic replacement, bus bridging, and protocol adaptation where a soft processor or custom datapath must be implemented in programmable logic. When designing with this part, note that APEX 20KE silicon is mature and several derivative part numbers exist; engineers should verify pin compatibility for any drop-in alternative, since the APEX 20KE family predates current Quartus toolchains and requires legacy MAX+PLUS II or Quartus support for bitstream generation. LVDS I/O termination, decoupling, and PCB stack-up must follow the APEX 20KE handbook guidelines for signal-integrity compliance at >200 MHz operation.
EP20K300EBC652-1X - APEX 20KE FPGA 300K Gates 11520 Cells 1.8V 652-BGA | Altera
The Intel / Altera EP20K300EBC652-1X is a member of the APEX 20KE programmable logic device family, delivering 300,000 system gates, 11,520 logic elements (cells), and 147,456 bits of embedded SRAM in a 652-ball BGA package. Fabricated on a 0.22 um CMOS process and powered from a 1.71 V to 1.89 V core supply, this device implements Altera's MultiCore architecture that integrates look-up table (LUT) logic, product-term logic, and embedded memory blocks on a single die, enabling system-on-a-programmable-chip (SOPC) integration. An FPGA (Field Programmable Gate Array) is a programmable logic device that combines configurable logic blocks, programmable interconnect, and I/O cells on a single silicon die, allowing engineers to implement custom digital hardware after fabrication. Within the broader integrated-circuit taxonomy, FPGAs sit between standard logic ICs (fixed-function gates, timers) and full custom ASICs: like ASICs they implement arbitrary digital functions, but unlike ASICs they can be reconfigured in the field. APEX 20KE devices specifically target high-density data-path and datapath-plus-control applications, combining LUT logic for register-intensive functions with product-term logic for wide combinatorial decode paths. Key features of the EP20K300EBC652-1X include up to 408 maximum user I/O pins, 4 embedded memory blocks totaling 147 Kbits, four phase-locked loops (PLLs) for clock synthesis, LVDS I/O support via the 1.8 V APEX 20KE I/O standard set, and a system frequency up to 400 MHz. The 652-ball BGA package measures 45 mm x 45 mm and is qualified for industrial temperature ranges, making the device suitable for telecom line cards, networking switch fabrics, and high-speed image processing pipelines. The architecture combines four types of MegaLAB structures, each containing 16 Logic Elements (LEs), one Embedded System Block (ESB) memory, and a local interconnect; 19 such MegaLABs form a MegaLAB array.

Altera EP20K300EBC652-2 is an APEX-20KE field-programmable gate array (FPGA) with 1152 macros, 147456 total RAM bits, and 408 I/O, supplied in a 652-ball BGA package measuring 45 mm by 45 mm. The device belongs to the programmable logic device hierarchy: FPGA, programmable logic device, and integrated circuit. It uses configurable logic resources and embedded memory to implement high-density digital systems. According to the verified distributor data, the part is identified as an APEX-20KE device with 1.71 V to 1.89 V supply voltage and 652-BGA packaging. The target MPN suffix indicates a specific speed or ordering variant, but the provided data does not expose a separate timing grade in machine-readable form. An FPGA is a semiconductor integrated circuit whose logic function is defined by configuration rather than fixed mask programming. FPGAs combine programmable lookup-table or macro logic, routing resources, memory, and I/O cells. In the broader electronics hierarchy, this places the device between a programmable logic device and a system-level digital implementation technology. The APEX-20KE family uses a 1.8 V-oriented platform, making the part suitable for designs that require configurable digital blocks without the fixed function constraints of an application-specific integrated circuit. The principal verified features are 1152 macros, 147456 total RAM bits, 11520 logic cells as reported by the DigiKey Marketplace result, and 408 I/O pins. The 652-BGA package provides a large ball-grid-array interface for high pin-count designs, while the 45 mm by 45 mm package dimensions are important for land-pattern, routing, and thermal planning. The 1.71 V to 1.89 V supply range should be treated as a system-level input requirement, and the exact board power implementation should be validated against the complete manufacturer documentation. The architecture is associated with configurable logic resources, embedded memory, programmable routing, and programmable I/O. The reported macro count and memory capacity indicate a high-density device intended for designs that would otherwise require several smaller programmable devices or substantial discrete logic. Because the provided search data does not include clock frequency, transceiver count, temperature grade, or configuration interface details, those characteristics are deliberately left for datasheet verification rather than inferred. Typical applications include industrial automation controllers, communications equipment, test and measurement systems, image or protocol processing, and embedded control platforms. In these systems, the FPGA can implement parallel datapaths, interface adaptation, state machines, and memory-intensive digital functions. The 408 I/O count is especially relevant where many external buses, sensors, converters, or control signals must be connected. Designers should confirm the configuration method, I/O banking, supported I/O standards, timing constraints, power sequencing, and operating temperature in the manufacturer datasheet before schematic release. A 652-ball BGA requires controlled-impedance routing, a suitable multilayer PCB, escape routing, and assembly capability. Pin-to-pin substitution should be limited to devices with verified package, ball map, speed, voltage, and configuration compatibility. This page combines verified distributor specifications, package information, cross-reference evidence, and application-oriented design guidance. It does not invent unsupported timing, temperature, or electrical values; unavailable engineering details are identified in the specification list for follow-up verification.

EP20K300EQC240-2X - APEX 20KE 300K Gates 240-PQFP FPGA | Altera
The Altera (Intel) EP20K300EQC240-2X is an APEX 20KE family FPGA delivering 300,000 system gates, 1,152 macrocells, and 152 user I/Os in a 240-pin Plastic Quad Flat Pack (PQFP/BQFP) measuring 32x32 mm. It is built on a 1.8 V core MultiCore architecture that integrates look-up table (LUT) logic, embedded system blocks (ESBs) for memory, and I/O elements into a single system-on-a-programmable-chip (SOPC) fabric. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be electrically configured by the designer after manufacture. FPGAs sit between fixed-function ASICs and software-programmable processors in the design hierarchy: they deliver hardware-level parallelism and deterministic timing like ASICs while retaining the flexibility of programmable logic. Within Altera's portfolio, the APEX 20KE family occupies the high-density SOPC tier, bridging the older APEX 20K series and later Stratix/Arria families. Key features include 1152 macrocells, 152 user I/Os, an internal core voltage of 1.71 V to 1.89 V (1.8 V nominal), a propagation delay of approximately 1.68 ns to 2.29 ns depending on speed grade, and an internal operating frequency of up to 160 MHz. The device supports in-system programmability via JTAG and is supported by the Quartus II design toolchain (legacy). The 240-PQFP gull-wing package is surface-mount compatible and follows JEDEC MS-022 standards. Typical applications include high-density glue logic, telecommunications backplane interfacing, custom peripheral bridging in industrial controllers, DSP pre/post-processing front-ends, and prototype ASIC emulation. The combination of high gate count and an embedded memory block array makes it well suited to bus-interface aggregation and protocol-conversion designs. When designing with this device, ensure 1.8 V core decoupling is placed adjacent to all VCCINT pins and that I/O bank voltages are configured to match downstream logic levels. The legacy 1.8 V core and 240-PQFP footprint mean modern PCB designs should verify JEDEC land-pattern compatibility before reuse.
EP20K300EQC240-2XN - Intel/Altera APEX 20KE FPGA 1.8V 240-PQFP
The Intel EP20K300EQC240-2XN is an APEX 20KE programmable logic device containing 11,520 logic elements, 152 user I/Os, 147,456 RAM bits, and 728,000 system gates in a 240-pin PQFP (32x32 mm) package. It operates from a 1.8 V core supply and is specified for the -2 speed grade and 0°C to +85°C junction temperature range. An FPGA is a field-programmable gate array, a semiconductor device whose logic blocks and programmable interconnect can be reconfigured after manufacturing. In the APEX 20KE architecture, logic elements (LEs) are grouped into logic array blocks (LABs), while embedded system blocks (ESBs) provide RAM, product-term logic, and high-speed FIFO functions. This blends the density of a gate array with the board-level flexibility of a programmable logic device, making it appropriate for medium-density digital systems that need a mix of register-rich logic, memory, and board-level I/O. Key features include a 0.22-um CMOS process, 350 MHz internal clock operation, 152 general-purpose I/Os, and 147,456 bits of embedded RAM. The -2XN ordering option combines a -2 speed grade with the lead-free N suffix, while retaining the APEX 20K family architecture. The device contains 1,152 LABs of ten LEs each, totaling 11,520 LEs, and can implement memory-intensive designs using ESB blocks without external SRAM. The 1.71-V to 1.89-V VCCINT rail reduces core power compared with earlier-generation APEX devices, while the 152 I/O pins allow wide data-path busses for parallel processing. Typical applications include communication line cards, industrial control logic, medical imaging front ends, test-and-measurement instruments, and legacy networking equipment that need mature parallel logic with wide I/O. The 240-pin PQFP is a conventional surface-mount package that is easier to solder and inspect than fine-pitch BGA alternatives, which is often valuable in legacy printed-circuit-board repair and low-volume restocking. When designing with this device, provide low-impedance decoupling on every VCC pin, connect all ground pins with short vias, and configure the FPGA with a compatible Altera/Intel EPC configuration device. Because this part is obsolete, always verify stock, lead time, and anti-counterfeit handling before building it into a long-life product. This page aggregates datasheet-level specifications, package/ordering alternatives, practical design guidance, and current sourcing context not typically found in the manufacturer datasheet. It is intended for engineers performing legacy board repair, BoM risk mitigation, and pin-compatible replacement analysis.
