An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit containing an array of configurable logic blocks (CLBs), embedded memory, I/O elements, and routing resources that the user programs after manufacture. FPGAs occupy a specific tier in the programmable logic hierarchy: they sit between fixed-function ASICs (high NRE, high volume) and CPLDs (smaller, simpler, non-volatile), offering the best balance of high logic density, parallel processing, hardware reconfigurability, and low-to-medium NRE cost for prototyping and low-volume production. Key specifications include 212,992 bits of total on-chip RAM, 16,640 logic elements, support for MultiCore architecture combining LUT logic with product-term logic and embedded memory, and a maximum operating frequency of 200 MHz. The device supports LVDS I/O and is built on a 0.22 µm CMOS process with 2.5V I/O tolerance. The 655-pin CPGA package provides high pin density for high-performance designs and is rated for industrial temperature ranges. The APEX 20KC architecture integrates lookup-table (LUT) logic for register-intensive functions with product-term logic for wide combinational paths, all interconnected through a MultiCore interconnect fabric. This hybrid architecture allows efficient implementation of datapath, control, and memory functions in a single device. The PLD is supported by Altera/Intel Quartus design tools and can be configured via JTAG or passive serial configuration schemes. Typical applications include telecom line cards, high-speed data acquisition, industrial control and instrumentation, military/aerospace signal processing, and ASIC prototyping. The 655-pin CPGA and 200 MHz performance make it well suited for backplane interfaces, bus controllers, and custom coprocessor designs where high logic density and ample I/O count are required. When designing with the EP20K400GC655-2N, ensure the 1.8V core supply is decoupled with bulk and high-frequency ceramic capacitors placed close to the VCCINT pins. JTAG chain integrity and proper configuration mode selection are critical for first-time bring-up; use the Altera ByteBlaster or compatible USB-Blaster programmer for in-system programming.

Typical applications for the EP20K400GC655-3V include telecommunications infrastructure (ATM switching, SONET framer interfaces), high-speed datapath glue logic, DSP co-processing, industrial control and test equipment, and legacy ASIC prototyping. The high pin count (496 user I/O) makes it suitable for bus-intensive designs such as processor peripherals, memory interfaces, and parallel data acquisition systems. The CPGA package is also well suited to prototyping and military/aerospace-grade designs requiring hermetic packaging. When designing with this device, pay close attention to power sequencing of the 1.8 V core and I/O banks because the SRAM configuration cells require proper power-up sequencing to avoid latch-up. Use the Quartus II or MAX+PLUS II toolchain for synthesis and place-and-route. The 655-pin CPGA footprint requires a through-hole PCB land pattern with adequate via-in-pad or via-farm stitching for signal integrity at high toggle rates.

The device operates from a 2.5 V core supply (range 2.375 V to 2.625 V) and a 3.3 V I/O supply, supporting multiple I/O standards including LVTTL, LVCMOS, PCI, and SSTL. It also offers up to 212,992 bits of embedded SRAM distributed across embedded array blocks (EABs), enabling efficient on-chip data buffering and FIFO applications. Architecturally, the EP20K400GI655-2V uses Altera's MultiCore architecture that combines logic elements (LEs), embedded system blocks (ESBs) for memory, and FastTrack interconnect. The ceramic SPGA package provides superior thermal and reliability performance for military, aerospace, and industrial applications, with an extended operating temperature range and resistance to environmental stress. Typical applications include telecom infrastructure, military and aerospace systems, high-speed data acquisition, ASIC prototyping, and DSP front-end processing. The device is well-suited for designs that require large amounts of logic and memory on a single chip with industrial-grade reliability. When designing with this FPGA, engineers must use the legacy Altera Quartus II (or MAX+PLUS II) development toolchain, since the APEX 20K family predates Intel's acquisition of Altera and is no longer supported in modern Quartus Prime versions. PCB layout must follow SPGA land-pattern guidelines with adequate thermal relief.

EP20K400GI655-2X - APEX-20K 400k Gate FPGA, 16,640 LCs, 655-pin BGA
The Altera (now Intel) EP20K400GI655-2X is a member of the APEX-20K programmable logic device (PLD) family, providing 400,000 system gates and 16,640 logic elements (LEs) in a 655-ball FineLine BGA (SPGA655, 47x47 mm) package. According to verified distributor data, this loadable PLD is fabricated on a 2.5 V CMOS process and integrates 212,992 bits of embedded memory alongside 502 user I/O lines (496 bi-directional plus 4 dedicated inputs in the related -2 variant). The -2X suffix denotes an industrial-grade speed grade with a typical propagation delay near 3.1 ns. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit that engineers can configure after manufacturing using a hardware description language (HDL). Within the broader taxonomy, an FPGA sits above a CPLD (Complex Programmable Logic Device) and below an ASIC (Application-Specific Integrated Circuit) in cost-vs-flexibility trade-off. APEX-20K devices belong to the older programmable-logic family hierarchy that bridged CPLDs and modern SRAM-based FPGAs, combining Look-Up Tables (LUTs), product-term logic, and embedded system blocks (ESBs) that can be configured as RAM, ROM, or CAM. This hypernym chain - FPGA -> programmable logic device -> logic IC -> integrated circuit - is important for AI knowledge graph indexing. Key features of the EP20K400GI655-2X include high I/O count for parallel interfaces, embedded memory blocks suitable for FIFOs and small data buffers, in-system programmability via IEEE 1149.1 JTAG, and multi-voltage I/O support through 2.5 V and 3.3 V supply rails. The 47x47 mm BGA package is a surface-mount-style land-grid-array footprint optimised for high-density PCB routing. Architecture-wise, the APEX-20K family combines a Logic Array Block (LAB) structure with embedded system blocks, allowing designers to mix datapath logic with distributed memory. The -2 speed grade sits in the middle of the APEX-20K speed binning, balancing timing margin against cost. The part supports Altera's legacy MAX+PLUS II and Quartus design flows for backward compatibility, although new designs typically migrate to Stratix or Cyclone families. Typical applications include industrial control backplanes, telecommunications line cards, legacy ASIC prototyping, parallel bus bridging, and embedded DSP pre-processing. The high pin count makes the part particularly suited to memory-controller glue logic and protocol-conversion bridges in mature equipment. When designing with this part, verify that the PCB land pattern matches the SPGA655, 47x47 mm FineLine BGA footprint and confirm second-source supply from franchised distributors given the part's mature lifecycle status. Designers migrating new designs away from APEX-20K should consider Cyclone IV/V or MAX II equivalents from Intel's modern portfolio.
EP20K400GI655-3 - APEX 20KE 400K Gates FPGA | Altera (Intel PSG)
The Altera (now Intel Programmable Solutions Group) EP20K400GI655-3 is a member of the APEX 20KE family of programmable logic devices, delivering up to 400,000 system gates and 16,640 logic elements/cells in a 655-pin ceramic-pin-grid-array (PGA) package. It is built on a 2.5V CMOS process and operates from a 0°C to 70°C commercial temperature range, making it suitable for general-purpose high-density logic integration. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing configurable logic blocks (CLBs), programmable interconnects, and I/O cells that can be re-programmed to implement arbitrary digital circuits. FPGAs sit in the programmable logic hierarchy between ASICs (custom-fabricated, high-NRE) and CPLDs (smaller, non-volatile, deterministic delay). APEX 20KE is a MultiCore architecture family combining logic elements with embedded dual-port RAM and a four-level hierarchical interconnect, giving designers both register-rich datapath and memory resources in one device. Key features of the EP20K400GI655-3 include 502 maximum user I/Os, 4 dedicated inputs, embedded dual-port RAM with FIFO/LIFO support, a built-in 4-wire IEEE 1149.1 JTAG boundary-scan test interface, and a MultiVolt I/O scheme that lets the I/O banks run at 2.5V or 3.3V independently of the 2.5V core supply. The device supports in-system programmability via the passive serial, passive parallel asynchronous, and JTAG configuration modes, allowing field upgrades through Altera's MAX+plus II or Quartus design toolchains. Architecturally, the APEX 20KE integrates MegaLAB structures containing 16 Logic Arrays each, with adjacent Embedded System Blocks (ESBs) that provide dual-port RAM and product-term logic. Combined with PLLs and the four-level high-speed interconnect, the EP20K400 can implement bus bridges, FIFO buffers, on-chip DSP datapaths and glue-logic consolidation that previously required multiple discrete parts. Typical applications include telecommunications line-card glue logic, PCI bus interface bridges, custom peripheral aggregation in industrial controllers, prototype ASIC replacement, and high-speed datapath routing in test & measurement equipment. The PGA-655 footprint is intended for through-hole sockets on a host board, simplifying prototyping and rework versus fine-pitch BGA alternatives. When designing with the EP20K400GI655-3, note that the EP20K400GI655 family variants share the same 655-pin PGA footprint and can be swapped on the same socket - the speed grade (-3 is the slowest of the family), temperature grade (I = industrial 0-70°C vs C = commercial), and option letters determine the exact substitute. Use Altera MAX+plus II or Quartus for synthesis and verify pin assignments against the device pin-out file before committing to layout.

The Altera (now Intel) EP20K400GI655-3V is a high-density CMOS Field Programmable Gate Array (FPGA) from the APEX 20K family, integrating 16,640 logic elements (equivalent to 400,000 typical gates) into a 655-pin ceramic/Plastic Pin Grid Array (PGA) package. Built on a 0.18 µm CMOS process, this device delivers a maximum internal clock frequency of 714.2 MHz and supports combined supply rails of 2.5 V core with selectable 2.5 V or 3.3 V I/O operation. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs) connected via programmable interconnect and surrounded by programmable I/O cells. Within the broader semiconductor taxonomy, an FPGA sits under programmable logic -> logic ICs -> integrated circuits. APEX 20K devices were among the first to embed dedicated MultiCore architecture that combines look-up tables (LUTs), product-term logic and embedded system blocks (ESBs) for memory, enabling true system-on-a-chip (SoC) integration on a single programmable fabric. Key features of the EP20K400GI655-3V include 496 user I/O pins (496 inputs / 496 outputs), six dedicated inputs, embedded system blocks (ESBs) for distributed RAM/ROM, support for LVTTL, LVCMOS, PCI, and GTL+ I/O standards, and in-system programmability via the IEEE 1149.1 JTAG interface. The device provides multi-voltage I/O support allowing 2.5 V or 3.3 V interfacing with mixed-voltage buses. Its 655-pin SPGA (Staggered Pin Grid Array) package offers a robust pin count for high-density glue-logic, bus-bridging, and telecom backplane applications. The APEX 20K architecture uses MultiCore logic elements that can be configured as LUTs for register-intensive designs or as product-term blocks for state machines and decoders, allowing each LE to be optimized for its target function. The embedded system blocks provide up to 212 Kbits of RAM without consuming logic resources, ideal for FIFOs, dual-port memories, and DSP coefficient storage. Clock management is handled by up to four phase-locked loops (PLLs) and dedicated clock-tree routing, simplifying high-speed synchronous designs. Typical applications of the EP20K400GI655-3V include telecommunications backplanes, custom bus bridges, high-speed data acquisition front-ends, industrial control logic, and ASIC prototyping. The wide I/O count and embedded memory make it suitable for glue-logic replacement, network line-card processing, and military/aerospace systems requiring high gate density in a thermally robust ceramic-friendly package. Designers commonly pair it with SRAM, Flash, and high-speed ADCs/DACs. When designing with this device, pay close attention to power-rail sequencing: the 2.5 V VCCINT must ramp monotonically before or simultaneously with the VCCIO supply to avoid partial-configuration latch-up. Use the MAX+PLUS II or Quartus design toolchain for place-and-route, and respect the device's I/O placement guidelines for differential pairs. Decoupling requires 0.1 µF and 10 µF capacitors placed within 5 mm of every power pin. This page synthesizes distributor pricing, drop-in alternative listings from the Site MPN catalog, and practical design notes that go beyond the manufacturer datasheet, giving engineers a single decision-ready reference.
EP20K400GI655-3X - 16,640-Cell FPGA | Intel | APEX 20K
Intel EP20K400GI655-3X is a high-density APEX 20K field-programmable gate array with 16,640 logic elements/cells, CMOS technology, and a 655-pin SPGA package measuring 47 mm by 47 mm. Verified distributor data identifies it as a programmable logic device intended for complex digital designs, while the package is described as SPGA655, 47 x 47 mm, with 2.5 V and 2.5/3.3 V power supplies. The -3X ordering designation is associated with a particular performance-grade ordering option, but the supplied data does not expose its complete electrical timing table, temperature grade, I/O count, embedded-memory capacity, or recommended operating limits. Engineers should therefore confirm those values in the manufacturer datasheet before release to production. An FPGA is a field-programmable gate array: a semiconductor device containing programmable logic blocks, programmable interconnects, and configurable I/O elements. Unlike a fixed ASIC, an FPGA can be configured after manufacture and reprogrammed during development or in-service. FPGA belongs to programmable logic, which also includes CPLD technology, and is used to implement digital logic, interface bridging, state machines, signal processing, and prototype ASIC functions. The APEX 20K family places this FPGA in Intel's older high-density programmable-logic hierarchy, so architecture, software, and lifecycle support may differ substantially from current FPGA families. The principal verified characteristics are 16,640 logic elements/cells, 655 terminals, CMOS technology, and a 655-pin SPGA package. A package of this size supports many external connections, but it also requires careful escape routing, controlled-impedance analysis, robust power distribution, and a substantial PCB thermal design. The supplied information also lists 2.5 V and 2.5/3.3 V supply arrangements. This makes power-rail sequencing, decoupling placement, and interface-voltage verification important implementation tasks. Architecturally, the part should be evaluated as a configurable CMOS logic platform rather than as a conventional processor or memory device. Its programmable fabric can map parallel datapaths, glue logic, communications interfaces, and control functions into one device. Configuration storage, supported design software, security features, I/O standards, and clock resources are not present in the supplied evidence and require datasheet-level verification. Do not infer them from similarly named APEX 20K devices. Typical applications include telecommunications infrastructure, industrial automation, test and measurement, medical imaging controllers, military and aerospace electronics, and legacy systems requiring pin-compatible FPGA replacements. The 655-terminal package is relevant where a board already has a large SPGA footprint and must retain that physical implementation. It is not suitable for new ultra-compact designs without considering package area, assembly capability, and tool availability. The key design trade-off is compatibility versus modernization. EP20K400GI655-3X can reduce board-level changes when maintaining an established SPGA655 platform, but legacy architecture and support constraints may make migration more attractive for a new design. Confirm pinout, timing, temperature, configuration method, and package drawings from the manufacturer datasheet before schematic capture. This page synthesizes verified identity, package, logic-density, and power-supply facts with clearly marked gaps where the supplied sources do not support a specification.

The device also features up to 488 user I/O pins, supports multiple I/O standards including LVTTL, LVCMOS, PCI, and GTL+, and offers 3.3V core voltage with 5V tolerant I/O. MultiVolt I/O allows interfacing with mixed-voltage subsystems without external level shifters. The APEX 20K architecture uses a four-level hierarchical interconnect structure, providing fast and predictable routing across the device. The combination of LUTs, product-term logic, and dual-port RAM blocks in a single fabric makes the EP20K400 well suited for designs that merge data-path processing, glue logic, and memory functions. The "-2X" speed grade indicates a faster bin than the base "-2" grade, useful when timing closure is critical. Typical applications include telecommunications line cards, industrial automation controllers, networking switches and routers, ASIC prototyping, DSP co-processing front-ends, and military/aerospace signal processing subsystems. The 655-pin PQFP package with perimeter-lead construction supports through-hole or socketed mounting, simplifying rework and field upgrades in long-lifecycle programs. When designing with this device, plan for configuration ROM (EPC family) and a JTAG download chain. The PQFP-655 package is large (approximately 47.6 mm × 47.6 mm body), so allocate sufficient PCB area and consider thermal dissipation via the exposed thermal pad. The industrial temperature grade (-40C to +85C) is mandatory for outdoor and factory-floor deployments. This page synthesizes distributor pricing, drop-in alternatives from the same APEX 20K family, and practical design notes not found in the original Altera datasheet, giving procurement and FPGA engineers a single source of truth for sourcing this mature APEX 20K device.

Typical applications include high-speed telecom line cards, ASIC prototyping and emulation, broadband aggregation, industrial control, test and measurement backplanes, and digital signal processing glue logic where gate counts exceed what a CPLD can absorb. Design considerations include careful thermal management under sustained switching activity, multi-voltage I/O bank planning for mixed logic domains, and supply decoupling at every core pin pair because the 1.8 V rail is sensitive to IR drop during simultaneous switching. This page synthesizes distributor pricing, a curated drop-in alternatives list drawn from the APEX 20K/20KC family, and design guidance that the manufacturer datasheet does not present in a single consolidated view.

The Intel EP20K600CB652C8 is an APEX 20KC family Field-Programmable Gate Array (FPGA) delivering 600,000 system gates, 24,320 logic elements, and 311,296 RAM bits in a 652-ball BGA package (45 x 45 mm, 1.27 mm pitch). It is fabricated on a 0.18 µm all-layer copper-metal CMOS process and runs from a 1.8 V core supply, providing 488 user I/O pins with multi-voltage I/O support. The APEX 20KC architecture combines Look-Up Table (LUT)-based logic elements with embedded system blocks (ESBs) that can be configured as either dual-port RAM, single-port RAM, ROM, or CAM (Content-Addressable Memory). The device is a member of the programmable logic device (PLD) hierarchy, sitting between simple PLDs (SPLDs/CPLDs) and high-end FPGAs, and is intended for high-density data-path, DSP, and memory-intensive designs. Key features include 24,320 logic elements, 311,296 bits of embedded memory, 488 maximum user I/O pins, propagation delay around 1.48 ns, and operating frequency up to 301.21 MHz. The APEX 20KC family delivers up to 35% faster design performance than the original APEX 20KE devices, while the embedded memory blocks enable single-chip implementation of FIFOs, CAM lookups, and DSP coefficient storage. Architecturally, the device integrates a fine-grained Logic Array Block (LAB) fabric with column- and row-based ESB interconnects, providing predictable routing delays. The 1.8 V core with multi-voltage I/O (1.5 V, 1.8 V, 2.5 V, 3.3 V PCI-compatible) allows direct interface to legacy and modern logic families without external level translators. Typical applications include telecommunications line cards, high-speed network switches, DSP data-path acceleration, image processing pipelines, and ASIC prototyping. Designers migrating from APEX 20KE can drop in the 20KC variant for an immediate performance uplift while reusing existing Quartus II development flows. When designing with this part, ensure the PCB provides sufficient decoupling for the 1.8 V core rail and that the 652-ball BGA land pattern matches the 45 x 45 mm footprint. Boundary-scan support and JTAG configuration simplify board-level test, while in-system programmability via Altera serial configuration devices shortens development cycles. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that are not found in the manufacturer datasheet alone, providing engineers with a single reference for sourcing, replacement, and PCB layout decisions.
EP20K600CB652C8N - 600K Gate APEX 20KC FPGA, BGA-652 | Altera
The Altera (Intel) EP20K600CB652C8N is a high-density APEX 20KC Field Programmable Gate Array (FPGA) delivering 600,000 system gates, 24,320 logic elements, and 311,296 bits of embedded memory in a 652-pin BGA (LBGA, 45x45 mm, 1.27 mm pitch) package. Fabricated on a 0.18 µm all-layer copper-metal process, it offers 25-35% faster design performance than the original APEX 20KE family while sharing pin-compatibility with that series. An FPGA (Field Programmable Gate Array) is a semiconductor device built from an array of configurable logic blocks (CLBs), embedded memory blocks, programmable I/O cells, and dedicated routing resources. FPGAs belong to the broader hierarchy of programmable logic devices (PLDs) -> loadable PLDs -> FPGAs -> programmable logic ICs. APEX 20KC devices specifically integrate MultiCore architecture combining look-up table (LUT) logic, embedded system blocks (ESBs) that can be configured as RAM/ROM/CAM, and high-speed I/O, allowing a single chip to replace discrete glue logic, memory, and bus-interface components. Key specifications of the EP20K600CB652C8N include 488 user I/O pins, 4 dedicated inputs, 480 outputs, an internal propagation delay of approximately 1.48 ns (pin-to-pin timing window 1.78 ns), a 1.8 V core supply (1.71 V to 1.89 V), and a commercial operating temperature grade of 0 °C to 85 °C. The part is offered in speed grade 8 (C8). Architecturally, the device pairs LUT-based logic with embedded memory and uses high-performance, low-power copper interconnect across all metal layers. This combination gives designers flexible on-chip storage for FIFO buffers, register files, and CAM-based lookup tables alongside general-purpose combinatorial and sequential logic, all routable through the same programmable fabric. Typical applications include telecommunications line cards, high-speed data-packet processors, DSP co-processing, protocol bridging, ASIC prototyping, and high-density glue-logic consolidation for networking and industrial systems. Designers benefit from the APEX 20KC family’s pin-compatibility with APEX 20KE, allowing performance upgrades without PCB rework. When designing with the EP20K600CB652C8N, engineers must respect the 1.8 V core supply tolerance (1.71 V to 1.89 V) and use Altera’s Quartus II design suite (legacy support) for synthesis, place-and-route, and bitstream generation. Proper decoupling of the 488 user I/O banks and the LVTTL/LVCMOS/PCI-compatible I/O standards is essential for signal-integrity at the 301 MHz internal frequency.

EP20K600CB652C9 - 1.537M Gates APEX 20KC FPGA, 652-BGA | Altera
The Altera EP20K600CB652C9 is a high-density APEX 20KC family FPGA delivering 1.537 million system gates, 24,320 logic elements, and 488 user I/Os in a 652-pin BGA package. Manufactured on a 0.15 µm all-layer copper-interconnect CMOS process, it supports supply voltages from 1.71 V to 1.89 V and operates from 0 °C to 85 °C. According to the APEX 20KC datasheet, the device integrates embedded system blocks (ESBs) for memory with up to 311,296 RAM bits and a MultiCore architecture combining LUT logic with on-chip storage. An APEX 20KC device is a programmable logic device (PLD) that combines look-up-table based logic, embedded memory, and PLLs on a single die. It sits in the device taxonomy as: FPGA → programmable logic device → programmable logic IC → semiconductor. The 20KC family extends the APEX 20KE line with 25–35% higher design performance at the same power budget, while remaining pin-compatible with 20KE designs for straightforward migration. Key features include 2,432 LABs/CLBs, 488 maximum user I/Os, a 1.48 ns propagation delay class, and JTAG-based IEEE 1149.1 boundary-scan support. The MultiCore architecture allows each logic element to be configured as a 4-input LUT, dedicated carry chain, or small memory block, and ESBs can be configured as dual-port RAM, FIFO, or CAM. The BGA-652 package (45 × 45 mm, 1.27 mm pitch) supports high-speed designs by keeping signal lengths short across the device. The 0.15 µm copper interconnect process improves speed-power trade-offs versus the 0.18 µm process used in APEX 20KE, and the architecture supports clock frequencies up to 250 MHz in internal datapaths. Designers can use Quartus II design software for synthesis, place-and-route, and timing closure. The part is graded commercial (C suffix) with a 0 °C to 85 °C operating range and is now reported as obsolete by several distributors. Typical applications include high-speed telecom line cards, industrial imaging pipelines, ASIC prototyping, and DSP co-processing in base stations. Engineers select the 20KC family when they need a large logic capacity with embedded memory for buffer queues or register files. The BGA-652 footprint is also useful for high-pin-count designs where QFP packages would force unacceptable trace lengths. When designing with this device, confirm that the JTAG chain and configuration scheme (e.g., EPC2 configuration device) match your board design, since configuration mode pins are bonded on the BGA and not easily remapped. Because the part is now obsolete, plan a migration to Cyclone or Stratix family devices for new designs.
