EP20K200EQI240-2N - 200K Gate APEX-20KE FPGA, 168 I/O | Intel

The Intel (Altera) EP20K200EQI240-2N is a 200,000-gate APEX-20KE series Field Programmable Gate Array (FPGA) housed in a 240-pin PowerQuad Flat Pack (PQFP/BFQFP) package with 168 user I/Os. Built on a 0.18 um CMOS process, the device delivers 8,320 logic elements organized into 832 LABs/CLBs and includes 106,496 bits of embedded RAM. Operating from a 1.8 V core supply with a 2.5 V I/O supply, it supports system clock rates up to 205 MHz per the APEX-20KE family datasheet. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines configurable logic blocks, programmable interconnects, and dedicated I/O cells on a single semiconductor die. APEX-20KE belongs to the MultiCore architecture family, integrating look-up table (LUT)-based logic with embedded memory blocks called ESBs (Embedded System Blocks). The hierarchy is: APEX-20KE -> APEX 20K family -> programmable logic device -> logic IC -> integrated circuit. APEX-20KE was the industry's first PLD family to combine LUT logic with on-chip system-on-a-programmable-chip (SOPC) integration, enabling designers to implement complex glue logic, register-heavy datapaths, and memory functions on a single device. Key features include 832 LABs/CLBs with 8,320 logic elements, 106,496 bits of embedded system block (ESB) RAM, 168 user I/Os, and a -2 speed grade for higher performance. The MultiCore architecture combines look-up table logic with embedded memory in a single fabric, while the 240-pin PQFP/BFQFP gull-wing package provides a 2.5 ns propagation delay window suitable for high-speed interface bridging. The 'EQI' suffix denotes the industrial 0 to 85 C operating range, while '240' specifies the 240-pin PQFP package. The device is well suited for ASIC prototyping, custom peripheral bridging, register-intensive datapath control, and high-density glue logic replacement. The 240-pin PQFP footprint makes it practical for designs targeting legacy through-hole-style land patterns where BGA reflow is undesirable, and the industrial temperature range supports factory-floor and instrumentation applications. This page synthesizes distributor pricing, drop-in alternatives, and engineering design notes for EP20K200EQI240-2N that are not found in the original APEX-20KE datasheet, providing practical guidance for engineers designing with or sourcing this legacy Intel/Altera FPGA family.

EP20K200EQI240-2X

EP20K200EQI240-2X - APEX 20KE FPGA 168 I/O | Altera

The Altera EP20K200EQI240-2X is an APEX 20KE Field Programmable Gate Array (FPGA) with 8320 logic elements, 168 user I/O lines, and 106496 RAM bits, supplied in a 240-terminal plastic PQFP package. According to the Microchip USA product listing, the device delivers a maximum clock frequency of 160MHz and a propagation delay of 1.97ns while operating from a 1.8V ±0.18V core supply across -40°C to +100°C. An FPGA is an integrated circuit whose logic fabric can be reprogrammed after manufacturing. The APEX 20KE family, originally from Altera, combines look-up-table (LUT) logic, product-term logic, and embedded memory in a MultiCore architecture, enabling system-on-a-programmable-chip (SOPC) integration. In the programmable logic hierarchy, the EP20K200EQI240-2X belongs to FPGA / CPLD programmable logic / integrated circuit, and the 20KE line is associated with 1.8V core operation and LVDS interfaces. Key differentiating features include 8320 logic elements for flexible datapath and control logic, 106496 RAM bits for FIFOs, buffers, and embedded storage, 168 user I/O lines plus 4 dedicated inputs, and a 240-pin PQFP with 0.5mm pitch. The 0.22um CMOS process provides a balanced speed-versus-power profile, while the industrial-temperature option covers -40°C to +100°C, making the device usable in environments beyond commercial 0°C to 85°C parts. From a technical architecture perspective, the MultiCore structure lets designers place register-intensive functions in LUT logic, decode and state-machine functions in product-term logic, and memory-intensive functions in embedded RAM blocks, reducing the number of external components. With a 160MHz clock capability and 1.97ns propagation delay, the EP20K200EQI240-2X is suitable for medium-speed line-card, video, control, and instrumentation designs where parallel I/O and on-chip memory are critical. Typical applications include telecom line cards, DSP co-processing, digital video processing, industrial controllers, and test-and-measurement instruments that require 168 I/O channels and embedded RAM in one package. The 1.8V core reduces switching power at high utilization, and the abundant user I/O allows direct connection to wide parallel buses without additional external shift registers or bus switches. When designing with this FPGA, pay attention to SRAM-based configuration requirements: APEX devices need a configuration device or download cable at power-up. Decouple every supply pin with low-ESL ceramic capacitors and provide bulk capacitance to keep VCCINT within the specified 1.8V ±0.18V range. This page combines distributor availability data, drop-in Altera APEX 20KE alternatives, comparison tables, and practical layout notes, giving design engineers information that goes beyond a simple datasheet listing.

EP20K200FC484-1

EP20K200FC484-1 - APEX 20K 200K Gates FPGA | Altera

The Altera (now Intel) EP20K200FC484-1 is a member of the APEX-20K family of Field Programmable Gate Arrays (FPGAs) with 200K equivalent gates, 8320 logic elements/cells, and 106,496 RAM bits, housed in a 484-ball FineLine BGA (FBGA) surface-mount package. It operates from a 2.5 V core supply, is fabricated on a 0.22 µm CMOS process, and is specified for the commercial 0 °C to 85 °C temperature range. The device integrates 382 I/O pins and supports up to 250 MHz internal operation. An FPGA (Field Programmable Gate Array) is a type of programmable logic device that allows hardware designers to configure digital logic, memory blocks, and I/O behavior after manufacturing. Within the integrated-circuit hierarchy, FPGAs sit between general-purpose microcontrollers (fixed architecture, software-defined behavior) and ASICs (fixed-function, custom-silicon performance). The APEX-20K family was Altera's first MultiCore architecture combining look-up table (LUT) logic, embedded system blocks (ESBs) for memory, and I/O elements - pioneering the system-on-a-programmable-chip (SOPC) integration concept that became standard in later FPGA generations. Key features include 200K system gates of logic capacity, 8320 logic elements, 106 Kbits of embedded SRAM distributed across embedded system blocks, 382 user I/Os for high-pin-count designs, MultiCore architecture combining LUT logic with embedded memory, in-system programmability via IEEE 1149.1 JTAG, and dedicated clock-management circuitry with phase-locked loops. The 484-pin FBGA package provides fine-pitch surface-mount assembly suitable for high-density PCB designs. Typical applications include telecommunications line cards, networking infrastructure, DSP co-processing, industrial control systems, and legacy designs requiring replacement of obsolete APEX-20K silicon. The wide I/O count and embedded memory make it particularly suited for bus-interfacing, protocol bridging, and glue-logic aggregation around larger processors. When designing with this device, verify the exact footprint against the Intel/Altera footprint library because legacy Altera FBGA ball maps must be matched precisely. Engineers should also confirm JTAG programmer support, as the original ByteBlaster and MasterBlaster cables require Altera Quartus versions supporting APEX-20K. The "-1" speed grade denotes the fastest available bin for this die.

EP20K200FC484-1N

EP20K200FC484-1N - APEX 20K 200K Gates FPGA 484FBGA | Intel / Altera

The Intel / Altera EP20K200FC484-1N is a member of the APEX 20K programmable logic device (PLD) family that delivers approximately 200,000 system gates and 8,320 logic elements (LEs) in a 484-ball FineLine BGA package. It uses a 0.22 µm CMOS process, operates from a 2.5 V core supply (2.375 V–2.625 V), and provides up to 382 user I/O pins. The device is rated for a commercial operating temperature range of 0 °C to 85 °C and supports an internal clock frequency up to 250 MHz. What is an FPGA? An FPGA (Field-Programmable Gate Array) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be rewired after manufacturing to implement arbitrary digital logic. APEX 20K was the industry's first PLD family to combine LUT-based logic, product-term logic, and embedded memory on a single MultiCore architecture die, enabling true system-on-a-programmable-chip (SOPC) integration. APEX 20K belongs to the broader PLD hierarchy: PLD -> CPLD/FPGA -> SRAM-based FPGA -> LUT + embedded memory FPGA -> SOPC. Key features of the EP20K200FC484-1N include 8,320 logic elements, approximately 200 K usable gates, embedded ESB (Embedded System Block) memory for distributed dual-port RAM or CAM, fast on-chip interconnect with predictable timing, JTAG-based IEEE 1149.1 boundary-scan test support, and a dedicated configuration interface compatible with Altera's ByteBlaster/MasterBlaster download cables. The device also integrates MultiVolt I/O support and supports LVTTL, LVCMOS, SSTL, and GTL signaling standards on its user I/Os. The EP20K200FC484-1N targets mid-density gate-array replacement, custom DSP datapaths, and bus-interface glue logic. Designers select APEX 20K when a design requires more logic capacity than a CPLD but does not yet need a Stratix-class FPGA, and when the design benefits from mixed LUT/product-term logic for state machines combined with embedded memory for FIFOs and register files. The 2.5 ns propagation delay (per third-party listings) makes the device suitable for PCI, 66 MHz synchronous logic, and protocol bridging. Typical applications include telecommunications line cards, industrial control backplanes, custom data-path acceleration, legacy PCI/PCI-X bridge designs, and ASIC prototyping. The 382 user I/Os are sufficient for 32-bit external memory buses plus auxiliary peripheral interfaces. A critical design consideration when using EP20K200FC484-1N in 2026 is the part's lifecycle status: APEX 20K has been in production for over two decades and is generally classified as mature/end-of-life. Designers should verify long-term supply with franchised distributors such as Rochester Electronics (an authorized Altera/Intel after-market partner). For new designs, the Cyclone or MAX families are recommended unless pin-exact drop-in replacement is required. This page synthesizes distributor pricing, drop-in alternatives from the same APEX 20K family, and engineering notes not found on a single manufacturer datasheet.

The Intel (Altera) EP20K200FC484-1XV is a member of the APEX 20K family of Field Programmable Gate Arrays (FPGAs) that delivers up to 200,000 typical system gates and 8,320 logic elements in a 484-ball FineLine BGA package. It is built on a 0.22 micrometer process and operates from a 1.71 V to 1.89 V core supply with a maximum internal frequency around 250 MHz. The part is supplied in the FC484 (484-FBGA 23x23 mm) package with a -1 speed grade. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be electrically configured by the designer after manufacturing to implement arbitrary digital logic. APEX 20K sits in the hierarchy: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit (IC). FPGAs fill the role between fixed-function ASICs and software-defined microcontrollers, providing hardware-level parallelism and reconfigurability for prototyping, glue logic, signal processing and pre-silicon verification. Key specifications include 8,320 logic elements, 106,496 bits of embedded system RAM distributed across 4 ESBs (Embedded System Blocks), 382 maximum user I/O pins, and 4 phase-locked loops (PLLs) for clock management. The device uses the APEX 20K multi-level architecture that combines look-up table (LUT)-based logic elements with high-density memory, and supports configuration via the Altera (now Intel) Quartus II design tool chain, with legacy Max+Plus II support still used in long-life programs. Typical applications include telecommunications infrastructure (SONET/SDH framer glue, ATM switching, DSLAM line cards), high-speed data acquisition front-ends, custom DSP co-processing pipelines, and military/aerospace systems where the APEX 20K family has a deep installed base. Long-life defense and industrial automation programs continue to specify APEX 20K because of mature firmware and verified reference designs. When designing with this FPGA, ensure 1.8 V core decoupling and 2.5 V/3.3 V I/O bank supplies are properly decoupled near the 484-FBGA balls. Confirm PCB escape routing for the 1.27 mm pitch BGA and respect JTAG programming pin assignments. For new designs, Intel recommends the Cyclone or Stratix families, but for cost-down or lifetime-extension of legacy APEX 20K boards the -1XV speed grade remains the mainstream choice. This page synthesizes distributor pricing, lifecycle observations, drop-in alternative variants within the APEX 20K family, and practical design notes not found in the manufacturer datasheet.

EP20K200FC484-2X - 200K Gates APEX 20K FPGA, 484-FBGA | Intel / Altera

The Altera (Intel) EP20K200FC484-2X is a member of the APEX 20K programmable logic family, delivering 200,000 system gates and 8,320 logic elements in a 484-pin FineLine BGA (FBGA) package. The device is fabricated on a 0.22 µm CMOS process with a 2.5 V core supply, and integrates 106,496 bits of embedded memory together with 382 user I/O pins, making it one of the highest-density members of the original APEX 20K lineup. An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) that combines configurable logic blocks (LUTs), programmable interconnect, and dedicated memory blocks on a single chip. The APEX 20K family introduced the MultiCore architecture that integrates lookup-table logic, product-term logic, and embedded array blocks (EABs) for on-chip SRAM, supporting system-on-a-programmable-chip (SOPC) integration. FPGAs occupy the broadest tier in the programmable logic hierarchy: PLD → CPLD → FPGA → SoC FPGA, with the APEX 20K family positioned as a high-density, embedded-memory-rich PLD. Key features of the EP20K200FC484-2X include a maximum internal clock frequency of 200 MHz, 8,320 logic cells (macro cells), 376 to 382 user I/Os depending on configuration, and 106 Kbit of embedded SRAM distributed across multiple EABs. The 484-pin FBGA package with 1.0 mm ball pitch supports compact board layouts and high-speed signal integrity. The device supports in-system programmability via the IEEE 1149.1 JTAG interface and the Altera ByteBlaster or MasterBlaster download cables, enabling rapid prototyping and production programming. The EP20K200FC484-2X uses a CMOS architecture with TTL-compatible I/O standards and supports multiple I/O voltages including 1.8 V, 2.5 V, and 3.3 V with LVDS support (the "-2X" speed/feature grade). The architecture integrates PLLs for clock management, dedicated high-speed carry chains for arithmetic, and Cascade chains for wide logic functions, providing a balanced blend of density, speed, and on-chip memory for data-path and control applications. Typical applications include telecommunications infrastructure (SONET/SDH framing, ATM switching), high-performance DSP pipelines, custom processor glue logic, and industrial control systems. The 382 available I/Os allow direct interface to wide external buses (32/64-bit) and high-density memory arrays without external muxing, while the embedded EABs enable single-chip implementation of FIFOs, dual-port RAM, and content-addressable memories. When designing with the EP20K200FC484-2X, pay particular attention to power-supply sequencing: the 2.5 V VCCINT and VCCIO rails must rise monotonically before any I/O switching occurs to prevent latch-up. Use the Quartus II (or legacy MAX+PLUS II) toolchain for synthesis, place-and-route, and timing analysis, and select the "FBGA-484" package symbol.

EP20K200FC484-3 - APEX 20K 200K FPGA, 8320 Cells, BGA-484 | Intel (Altera)

The Intel (formerly Altera) EP20K200FC484-3 is a member of the APEX 20K programmable logic device family, delivering 200K gates, 8320 logic elements (cells), and 382 user I/Os in a 484-pin FineLine BGA package. It is built on a 0.22 µm CMOS process and operates from a 2.5 V core supply with a -3 speed grade targeting 167 MHz internal performance. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, all of which can be re-programmed in the field. FPGAs sit within the broader hierarchy of programmable logic devices (PLDs) alongside CPLDs, and they are widely used as glue logic, prototyping vehicles, DSP engines, and ASIC-replacement platforms in telecom, industrial, and military designs. The APEX 20K family introduced the MultiCore architecture, which combines LUT-based logic (optimized for data-path, register-intensive, and DSP work) with product-term-based logic (optimized for state machines and complex combinational functions) and an embedded memory structure called ESBs (Embedded System Blocks). With 106,496 bits of on-chip RAM and 832 macrocells, the EP20K200FC484-3 implements system-on-a-programmable-chip (SOPC) integration, allowing designers to consolidate logic, memory, and bus interfaces into a single device. Typical applications include high-speed data-path processing, telecom line-card glue logic, DSP co-processing, bus-interface bridging, and prototype ASIC emulation. The -3 speed grade makes it suitable for designs where internal clock rates must reach into the 167 MHz range while still tolerating the commercial 0 °C to 85 °C operating envelope. Designers should plan for a 2.5 V VCCINT core supply, a separate VCCIO bank supply for I/O standards, and proper decoupling across the BGA-484 footprint. JTAG configuration via ByteBlaster or similar is the standard programming interface. Because the APEX 20K family is now in NRND/last-time-buy status with many distributors, life-cycle planning and second-source qualification is strongly recommended. This page synthesizes distributor stock and pricing signals, BGA-484 drop-in alternatives from the EP20K200 family, and practical design notes that go beyond the manufacturer datasheet to help engineers qualify or replace the EP20K200FC484-3 quickly.

EP20K200FC484-3AA - APEX-20K FPGA 200K Gates 484-BGA | Intel

The Intel (formerly Altera) EP20K200FC484-3AA is a member of the APEX-20K family of Field-Programmable Gate Arrays (FPGAs) that integrates look-up table (LUT) logic, embedded system blocks (ESBs), and high-speed I/O on a single MultiCore architecture die. The device provides 8320 logic elements, 832 Logic Array Blocks (LABs), 106,496 bits of embedded SRAM, and 382 programmable I/O pins in a 484-ball FineLine BGA package, organized as a system-on-a-programmable-chip (SOPC) fabric. It is rated for 526,000 maximum system gates and operates from a 2.375V to 2.625V core supply with a -3 (faster) speed grade and industrial-grade temperature rating. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that allows designers to implement arbitrary digital logic functions after PCB fabrication. APEX-20K FPGAs in particular combine fine-grained LUTs for random logic with coarse-grained Embedded System Blocks for memory and arithmetic, placing them in the broader hierarchy: logic cell -> LAB -> MegaLAB -> FPGA -> programmable logic -> semiconductor IC. This MultiCore architecture lets a single device absorb glue logic, register files, FIFO buffers, and even simple DSP datapaths, eliminating several support chips from the BOM. Key features include 382 user I/O pins supporting LVTTL, LVCMOS, PCI, and other single-ended I/O standards; hot-socketing support; in-system programmability via the IEEE 1149.1 (JTAG) interface and Altera serial configuration schemes; and on-chip PLLs for clock multiplication and skew management. The -3 speed grade places this device among the faster APEX-20K variants, improving Fmax for register-rich datapaths and reducing logic-synthesis-induced clock-period slack. Typical applications include high-volume telecom line cards, network switch backplanes, industrial motion-control boards, military/aerospace signal processing, and ASIC prototyping. The 484-BGA footprint supports dense board layouts, while the large I/O count enables multiple bus interfaces (PCI, SDRAM, LVDS) in a single chip. When designing, observe Altera's multi-voltage decoupling scheme (separate VCCINT, VCCIO banks, and VCCP_PLL rails), respect JTAG chain ordering, and verify configuration scheme compatibility against the EPC configuration device selected.

EP20K200FC484-3N

EP20K200FC484-3N - APEX-20K FPGA 200K Gates 484-FBGA | Intel

The Intel (formerly Altera) EP20K200FC484-3N is a member of the APEX-20K® family of Field Programmable Gate Arrays (FPGAs), delivering 200,000 system gates with 8,320 logic elements (Logic Array Blocks / MegaLABs) and 106,496 bits of embedded RAM in a 484-ball FineLine BGA package. The device combines a MultiCore™ architecture with look-up table (LUT) logic, embedded system-on-a-programmable-chip (SOPC) integration, and 382 user I/O pins, targeting complex glue-logic, bus-interface, and DSP datapath designs. The speed grade -3N indicates a commercial 0 to 85°C operating envelope with typical core logic propagation delays on the order of 2.5 ns, while the 484-FBGA (23 × 23 mm) package is supplied in a lead-free, surface-mount form factor. An FPGA (Field Programmable Gate Array) is a type of Programmable Logic Device (PLD) that combines configurable logic blocks, programmable interconnect, and often dedicated memory blocks and multipliers on a single piece of silicon. Within the semiconductor taxonomy, FPGAs sit below the hypernyms of programmable logic, programmable logic devices, and ultimately integrated circuits. The APEX-20K family was an early industry-first PLD that integrated hard IP for system-on-chip designs, foreshadowing today's SoC FPGAs that combine Arm cores with programmable fabric. Key specifications of the EP20K200FC484-3N include 200,000 system gates, 8,320 logic elements, 106,496 embedded RAM bits, 382 user I/Os, and a core voltage supply of 1.71 V to 1.89 V (VCCINT), with I/O supply on independent VCCIO rails. The device is fabricated on a 0.22 µm CMOS process and supports MultiVolt™ I/O, allowing 2.5 V, 3.3 V, or 5.0 V mixed-voltage interfacing with external memories, microprocessors, and bus transceivers. It also includes 4 phase-locked loops (PLLs) for clock management and supports LVDS, PCI, and other I/O standards. Programming is performed via JTAG (IEEE 1149.1) or the legacy Altera ByteBlaster / MasterBlaster / ByteBlasterMV interfaces using the Quartus II design tool flow (legacy Altera toolchain). Typical applications for the EP20K200FC484-3N include communications infrastructure (bridges, protocol converters, ATM/SONET framing), high-speed image processing, industrial automation controllers, PCI bus bridging and arbitration logic, DSP co-processing front-ends, and high-density glue logic replacing discrete TTL/CMOS ASICs. The combination of high gate count, ample I/O, and embedded RAM makes it particularly attractive for cost-sensitive, multi-standard interface designs that require a programmable but production-stable silicon platform. Because APEX-20K is an older generation, design teams are most commonly using it today for legacy product maintenance, end-of-life replacements, and long-lifecycle industrial / aerospace / defense systems. When designing with this part, ensure that the Quartus II (or later) toolchain supports the EP20K200 device family; many modern Quartus releases have dropped APEX-20K support, so designers must retain a legacy toolchain. Power sequencing, JTAG chain integrity, and I/O bank voltage compatibility should be validated against the APEX-20K datasheet before committing to a new board layout. The 484-FBGA package requires X-ray inspection and careful reflow profiling to avoid cold joints on the 1.0 mm pitch BGA balls.

EP20K200FC484-4 - 8320 LE FPGA, 382 I/O, 484-FBGA | Intel (Altera)

The Intel (formerly Altera) EP20K200FC484-4 is a member of the APEX-20K® family of Field Programmable Gate Arrays (FPGAs), delivering 8,320 logic elements, 106,496 RAM bits, and 526,000 gates in a 484-pin Fine-pitch Ball Grid Array (FBGA) surface-mount package. It provides 382 programmable I/O pins and is specified for an industrial-commercial operating temperature range of 0°C to 85°C, with a core supply voltage of 2.375 V to 2.625 V. The '-4' suffix denotes a specific speed grade within the APEX-20K family. An FPGA (Field Programmable Gate Array) is a type of integrated circuit that can be reconfigured by the designer after manufacturing, combining the programmable logic of a CPLD with the high density of an ASIC. Within the broader taxonomy, an FPGA belongs to the class of programmable logic devices, which are themselves a category of digital semiconductors used to implement custom digital circuits. The APEX-20K family was Intel/Altera's first generation to combine Look-Up Table (LUT)-based logic elements with embedded memory blocks, enabling a single chip to implement both glue logic and embedded system functions. Key features of the EP20K200FC484-4 include 832 logic array blocks (LABs) and 832 configurable logic blocks (CLBs), 106 Kbits of embedded SRAM, support for multiple I/O standards including LVTTL, LVCMOS, PCI, and GTL+, and an embedded PLL for clock management. The 382 user I/O pins are organized across eight I/O banks to provide flexible voltage-level interfacing. The 484-FBGA package offers a compact footprint with controlled-impedance traces suitable for high-speed parallel interfaces. The device is fabricated on a 0.18 µm CMOS process and combines LUT-based logic with a MegaLAB structure that groups multiple LABs and embedded system blocks (ESBs) for high-speed local interconnect. This architecture was widely adopted in telecom, networking, and data-acquisition designs in the early 2000s. Because the part is now in obsolescence, designs requiring long-term production should plan a migration path to a Stratix or Cyclone family device. Typical applications include high-density glue logic in telecom line cards, custom peripheral controllers in industrial automation, DSP co-processing front-ends, and ASIC prototyping. The combination of 526 K system gates and 382 I/O makes it suitable for designs that previously required multiple CPLDs. When designing with this part, pay particular attention to the 2.5 V core supply and I/O-bank reference voltage requirements; use the Altera MAX+PLUS II or Quartus design toolchain for synthesis, fitting, and timing closure. Because the EP20K200FC484-4 is end-of-life, verify last-time-buy and obsolescence notices with the manufacturer before committing to a new production design.

EP20K200FI484-2V - APEX-20K FPGA 200K Gates 484-FBGA | Intel / Altera

The Intel / Altera EP20K200FI484-2V is a member of the APEX-20K family of Field Programmable Gate Arrays (FPGAs), delivering 200,000 system gates (8320 logic elements / 106,496 RAM bits) in a 484-ball FineLine BGA (FBGA) package at industrial temperature grade. It is built on a 0.22 µm CMOS process and operates from a 2.5 V core supply, with MultiCore™ architecture combining look-up tables (LUTs), embedded system blocks (ESBs), and high-speed I/O elements on a single die. The device supports up to 382 user I/Os and is rated for 200 MHz internal operation, with a propagation delay figure of 2.5 ns referenced from the chipdig entry. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that uses an array of configurable logic blocks (CLBs), programmable routing, and programmable I/O cells to implement arbitrary digital logic. Within the programmable logic hierarchy, FPGAs sit above simple PLDs (PALs, GALs) and CPLDs because they integrate RAM, DSP, and even processor cores alongside the LUT fabric. The APEX-20K family was Altera's first System-on-a-Programmable-Chip (SOPC) family and was designed to absorb glue logic, memory, and high-speed interface functions onto a single silicon die. Key features of the EP20K200FI484-2V include 8320 logic elements, 106,496 bits of embedded memory distributed across multiple Embedded System Blocks, 4 phase-locked loops (PLLs) for clock management, and support for multiple I/O standards including LVTTL, LVCMOS, PCI, and HSTL. The -2V speed grade places it in the mid-band of the APEX-20K speed/grade matrix, balancing timing margin against cost. Operating temperature is specified as 0 °C to 85 °C (commercial-industrial), with the 'I' designator indicating the industrial temperature range. Architecturally, the APEX-20K family pioneered the MultiCore™ approach that fuses a fine-grained LUT fabric (Logic Array Blocks, or LABs) with coarse-grained Embedded System Blocks (ESBs) that implement dual-port RAM, ROM, or CAM in fixed sizes. The 484-ball FBGA package uses a 1.0 mm ball pitch to keep the die-area-to-board-area ratio high, which is critical for high-I/O-count designs. I/O banks are powered independently, allowing mixed-voltage interfacing on a single device. Typical applications for the EP20K200FI484-2V include telecommunications line cards, industrial automation controllers, PCI/CompactPCI bridge logic, high-speed serial protocol bridges, and ASIC prototyping. Its combination of large gate count, embedded memory, and flexible I/O made it a popular choice in late-1990s and early-2000s telecom infrastructure. The part is now an established legacy product; new designs should consider Cyclone IV/V or MAX series successors for cost and tool support. When designing with the EP20K200FI484-2V, ensure the Quartus II (or legacy MAX+PLUS II) toolchain is available because newer Quartus releases no longer support APEX-20K. Power sequencing of the 2.5 V core and any auxiliary I/O supplies must follow the datasheet sequence to avoid latch-up. The 484-ball FBGA requires X-ray inspection and BGA rework capability during prototyping.

It is fabricated on a 0.22 µm CMOS process, operates from a 2.5 V core supply with LVDS-capable I/O, and is specified for a maximum internal clock frequency of 250 MHz. A Field-Programmable Gate Array is a programmable logic device that combines configurable logic blocks (LUTs), programmable interconnect, and dedicated memory into a single silicon die. The APEX-20K family pioneered the MultiCore architecture that integrates look-up table logic, product-term logic, and embedded memory blocks on one die, enabling system-on-a-programmable-chip (SOPC) integration. FPGAs sit above fixed-function ASICs and below software-defined processors in the programmable logic hierarchy, and the APEX-20K sits within Altera's mid-density legacy FPGA portfolio alongside the FLEX 10K and APEX II families. Key features of the EP20K200RC208-1 include 144 maximum user I/O pins, four phase-locked loops (PLLs) for clock management, embedded array blocks (EABs) for memory and arithmetic, and in-system programmability via the IEEE 1149.1 JTAG interface. The device supports configuration through passive serial, passive parallel asynchronous, and synchronous modes, and is supported by the Quartus II (legacy) and MAX+PLUS II development tools. The exposed thermal pad on the bottom of the 208-BFQFP package enables direct heat extraction to a PCB copper pour. Typical applications for the EP20K200RC208-1 include telecommunications line cards, ASIC prototyping, glue logic consolidation, custom DSP datapaths, bus-interface bridges (PCI, PCIX, Utopia), and industrial control state machines. Designers typically select this part for cost-sensitive mid-volume designs where the APEX-20K's MultiCore architecture and embedded memory density provide an attractive balance of logic capacity, on-chip RAM, and unit price. When designing with the EP20K200RC208-1, follow the Quartus II power analysis flow and observe the 1.8 V LVDS I/O standard voltage limits. Multi-voltage rail sequencing (2.5 V core + 3.3 V/2.5 V I/O) is required, and the JTAG TMS/TCK pins must each have a 1 kΩ pull-up or pull-down to prevent erroneous configuration. Long-term availability for this EOL family should be confirmed with the manufacturer before new designs.

EP20K200RC208-1X - 200K Gates APEX-20KE FPGA, PQFP-208 | Intel

The Intel (formerly Altera) EP20K200RC208-1X is a member of the APEX-20KE programmable logic family, delivering 200,000 gates of MultiCore architecture logic in a 208-pin Power Quad Flat Pack (PQFP/RQFP) package. Built on a 0.18 µm CMOS process with a 1.8 V core supply, the device integrates look-up table (LUT) logic, product-term logic, and embedded memory blocks, supporting system-on-a-programmable-chip (SOPC) integration for high-density designs. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that engineers can reconfigure after manufacturing to implement custom digital logic. APEX-20KE extends the APEX-20K architecture by adding LVDS I/O support and a 1.8 V core, occupying the voltage regulator -> power management IC -> programmable logic -> semiconductor IC hierarchy within embedded systems. Compared with earlier 2.5 V APEX-20K devices, the -20KE family reduces power consumption while increasing logic density and signal integrity for high-speed interfaces. Key features include 8,320 logic elements, 106,496 bits of embedded RAM distributed across four lanes, 4 PLLs (where equipped), MultiVolt I/O supporting 1.8 V, 2.5 V, 3.3 V, and 5.0 V mixed-voltage interfacing, and LVDS support on select I/O banks. The "-1X" speed grade corresponds to a -1 device in the PQFP-208 pinout. Four enhanced PLLs with programmable phase shifting support clock multiplication, division, and delay, while the LVDS-compatible I/O enables high-speed serial data transfer up to 840 Mbps per channel. Typical applications for the EP20K200RC208-1X include telecommunications infrastructure (channelized TDM, ATM, and SONET/SDH processing), high-speed data-path and protocol bridging, custom ASIC prototyping, DSP coprocessor glue logic, and PCI/PCI-X bus interfaces. The 200 K-gate density makes it suitable for mid-volume designs that exceed the capacity of CPLDs but do not yet justify a full ASIC NRE cost. When designing with this part, account for the PQFP-208 package's fine 0.5 mm pitch lead frame - PCB layout requires controlled-impedance routing and careful thermal management for sustained operation. Configuration data is loaded via the IEEE 1149.1 JTAG interface or supporting configuration devices, with built-in CRC verification for in-system reliability.

EP20K200RC208-2 - APEX-20K 200K Gates FPGA, 208-RQFP | Altera

The Altera (now Intel) EP20K200RC208-2 is a member of the APEX-20K family of Field Programmable Gate Arrays (FPGAs), packaged in a 208-pin PowerQuad/QFP form factor with exposed thermal pad. The device integrates approximately 200,000 system gates and provides 8,320 logic elements backed by 106,496 bits of embedded SRAM, making it suitable for high-density logic and on-chip memory designs. The "RC208" suffix denotes the 208-pin BQFP/RQFP package, while the "-2" speed grade identifies an industrial-temperature, mid-speed variant optimized for balance between performance and cost. A Field Programmable Gate Array (FPGA) is a type of integrated circuit that can be configured by the customer or designer after manufacturing - hence "field-programmable". FPGAs occupy a hierarchy of programmable logic: programmable logic device (PLD) -> complex PLD (CPLD) -> FPGA -> system-on-chip FPGA. The APEX-20K family specifically combines look-up table (LUT) based logic with embedded memory blocks and a MultiCore architecture, allowing designers to implement glue logic, register-heavy datapaths, DSP blocks, and small to medium-sized microprocessors in a single device. Key features of the EP20K200RC208-2 include 144 maximum user I/O pins, 8320 logic elements (LEs), 106,496 RAM bits organized into embedded array blocks (EABs), and in-system programmability through the IEEE 1149.1 JTAG interface plus Altera's legacy configuration scheme. The device supports multi-voltage I/O standards including LVTTL, LVCMOS, PCI, and GTL+ on a per-pin basis, enabling mixed-voltage system integration without external level shifters. Architecturally, the EP20K200 implements Altera's MultiCore architecture with embedded array blocks (EABs) for memory and logic array blocks (LABs) routed via a continuous FastTrack interconnect. Each LE contains a 4-input LUT, a programmable register, and dedicated carry chain logic for arithmetic operations. The combination of LUT logic, EAB-based memory, and high fan-out routing makes the part well-suited to designs that require both moderate logic density and distributed RAM/ROM. Typical applications include telecommunications line cards, industrial control and machine vision, legacy ASIC prototyping, low-volume networking routers, and embedded control in industrial automation. The exposed thermal pad (EP) on the 208-RQFP package aids heat dissipation, allowing reliable operation at industrial temperature ranges. When designing with this part, ensure that the JTAG chain, configuration mode pins (MSEL), and power sequencing are correct for the chosen configuration EPROM. The APEX-20K family is now considered mature/legacy - designers should verify long-term availability through Rochester Electronics or franchised distributors and consider newer Cyclone or MAX series for new designs.

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.

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.

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.

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.

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.

EP20K200RI240-2

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
EP20K200RI240-2V

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.
