EP1SGX40GF1020I5 - 41,250 Logic Cells Stratix GX FPGA | Intel

The Intel (formerly Altera) EP1SGX40GF1020I5 is a high-performance Field-Programmable Gate Array (FPGA) from the Stratix GX family, integrating 41,250 logic elements, 4,125 Configurable Logic Blocks (CLBs), and 3,423,744 bits of embedded memory in a 1020-ball Fine-pitch Chip-Scale BGA package. Built on a 130 nm CMOS process with a 1.5 V core supply (1.425 V to 1.575 V tolerance), it supports up to 20 high-speed transceivers and is targeted at multi-gigabit serial I/O applications including Gigabit Ethernet, Fibre Channel, Serial RapidIO, and PCI Express. What is a Stratix GX FPGA? A Stratix GX is a high-density SRAM-based FPGA that integrates dedicated multi-gigabit transceivers (MGTs) alongside general-purpose programmable logic, embedded memory blocks, and DSP blocks on a single die. The GX family belongs to the broader category of programmable logic devices (PLD), which in the digital IC hierarchy sits between fixed-function ASICs and software-defined processors. Integrating transceivers with logic makes the Stratix GX especially suited for high-bandwidth serial interconnect applications where discrete PHY chips would otherwise consume board area and add latency. Key features include 3,423,744 embedded memory bits, 384 9x9 multiplier blocks, dedicated clock management with up to 12 PLLs, and high-speed transceivers operating up to 6.375 Gbps per channel. The 'I' speed grade denotes an industrial temperature range (-40 C to +100 C ambient), and '5' indicates the device speed bin within the Stratix GX family. The 1020-ball FC-FBGA (Flip-Chip Fine-pitch Ball Grid Array) package supports high I/O count and excellent signal integrity for backplane and line-card designs. Architecture-wise, the device employs a fine-grained logic element with a 4-input look-up table (LUT), a dedicated carry chain, and per-LUT register. Embedded TriMatrix memory provides three block sizes (512 bits, 4 Kbits, 512 Kbits) for flexible buffering. The transceiver channels implement clock data recovery (CDR) compliant with IEEE 802.3 clause 36 for Gigabit Ethernet, supporting /I2/ ordered-set clock compensation and rate matching through /K28.5/+/D16.2/- patterns. Typical applications include 10 Gigabit Ethernet line cards, Serial RapidIO bridges, PCI Express endpoints, base-station baseband processing, and high-end test & measurement backplanes. The integrated transceivers replace external PHY ICs and reduce board complexity. Designers also use the EP1SGX40GF1020I5 in broadcast video routing, defence signal processing, and storage area network (SAN) switching. A primary design consideration is PCB BGA fanout and escape routing for a 1020-ball package, which demands high-layer-count PCBs (typically 10+ layers) and 0.8 mm or 1.0 mm pitch escape techniques. Power estimation is critical because the transceiver analogue supply and core logic together can exceed 15 W at full utilization, requiring a multi-rail DC-DC architecture. JTAG and Active Serial configuration both supported; in-system programming is enabled via a dedicated AS configuration flash.

The Altera EP1SGX40GF1020I5N is a high-density Stratix GX family FPGA integrating 41,250 logic elements (4,125 CLBs) and 20 high-speed serial transceiver channels in a 1020-ball FineLine BGA (FC-FBGA) package on 1 mm pitch. Fabricated on a 130 nm CMOS process, the device operates from a 1.5 V core supply (1.425 V to 1.575 V) and supports transceiver data rates from 500 Mbps to 3.1875 Gbps, providing up to 127.5 Gbps of full-duplex serial bandwidth with embedded CDR/SERDES. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs), embedded memory, DSP blocks, and programmable interconnect. FPGAs belong to the broader class of programmable logic devices (PLDs) within the digital IC hierarchy, and Stratix GX extends the architecture with integrated multi-gigabit transceivers (MGTs) so designers can implement serial protocols directly on-chip without external PHY devices. Key features include up to 3.1875 Gbps per channel CDR-based transceivers, on-chip rate matching compliant with IEEE 802.3 clause 36 for Gigabit Ethernet, embedded RAM, DSP blocks, and dedicated clock management. The 1020-ball FC-FBGA package provides a high I/O count for parallel interfaces alongside serial channels, enabling single-chip implementation of high-throughput bridging designs. Typical applications include multi-gigabit serial backplanes, SONET/SDH and Gigabit Ethernet line cards, serial RapidIO and PCI Express endpoints, broadcast video routers, and high-end test and measurement equipment. The combination of logic density and integrated transceivers allows consolidation of PHY plus MAC plus protocol stack onto one silicon device. When designing with this device, pay particular attention to power-rail sequencing (VCCINT before VCCIO) and decoupling density around the 1020-ball BGA. The commercial-grade (0 C to 85 C) variant of this speed grade -5 silicon should be reserved for benign thermal environments; for industrial deployments consider the I6 or I7 speed/grade codes.

EP1SGX40GF1020I6

EP1SGX40GF1020I6 - Stratix GX FPGA, 41,250 LEs, 624 I/O | Intel

The Intel (formerly Altera) EP1SGX40GF1020I6 is a high-density Stratix GX family Field-Programmable Gate Array (FPGA) IC integrating 41,250 logic elements (LEs), 4,125 logic array blocks (LABs), and 3,423,744 bits of embedded memory in a 1020-ball FineLine BGA (FC-FBGA) package. The device is fabricated on a 130 nm CMOS process, supports up to 624 user I/O pins, and operates from a 1.5 V core supply with a maximum internal clock frequency of 5000 MHz, making it one of the highest-density transceivers-equipped FPGAs of its generation. What is an FPGA? A Field-Programmable Gate Array is a semiconductor integrated circuit built around a matrix of configurable logic blocks (CLBs/LABs), programmable interconnects, and dedicated hard IP blocks (memory, DSP, transceivers, PLLs). FPGAs occupy the middle ground between fixed-function ASICs and software-programmable processors: they are hardware-reconfigurable, parallel by design, and ideal for data-path-intensive workloads. Stratix GX specifically extends the Stratix family with multi-gigabit transceivers, targeting high-speed serial I/O such as Serial RapidIO, PCI Express, XAUI, and Fibre Channel. Key features of the EP1SGX40GF1020I6 include embedded transceivers supporting 3.125 Gbps data rates, up to 3.4 Mbits of RAM distributed across TriMatrix memory blocks, dedicated DSP blocks for high-throughput multiply-accumulate operations, and Stratix GX SignalTap embedded logic analysis. The 1020-ball FC-FBGA at 33x33 mm with 1 mm pitch supports high-pin-count designs where board-level signal integrity and power-delivery plane access are critical. Architecturally, the device combines 4125 LABs organized into rows and columns, surrounded by I/O elements (IOEs) on all four sides, and includes dedicated transceiver channels and phase-locked loops (PLLs) for clock synthesis. Compared with a hard-wired ASIC, the EP1SGX40GF1020I6 allows in-system reprogrammability, shorter time-to-prototype, and field upgradability, at the cost of slightly higher unit price and lower raw clock frequency per logic block. Typical applications include high-speed serial interface bridging (PCI Express, Serial RapidIO, XAUI), communications backplane aggregation, military radar and signal intelligence front-ends, broadcast video processing, and high-performance ASIC prototyping. The integrated 3.125 Gbps transceivers make the part particularly attractive for line-card designs where discrete PHY chips are not cost-effective. When designing with the EP1SGX40GF1020I6, pay close attention to PCB stack-up, BGA break-out escape routing, and decoupling of the 1.5 V core rail, since the device can draw significant transient current. Quartus II software (versions 5.0 and later) is the supported design flow; pre-synthesis pin assignments and SignalTap II logic analyzer cores are recommended for bring-up.

The 'GX' suffix designates the inclusion of multi-gigabit transceivers optimized for high-speed serial connectivity, while the 'I' speed grade and -40C to +100C industrial operating range address ruggedized applications beyond commercial envelopes. A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs), programmable interconnect, and dedicated hard IP such as transceivers, PLLs, and block RAM. FPGAs sit at the top of the programmable logic hierarchy (above CPLDs and PALs) and below ASICs in terms of unit volume per design. Stratix GX belongs to Altera's high-performance transceiver-equipped family, bridging discrete logic and ASIC-level integration by combining soft logic flexibility with hardened multi-gigabit serial I/O. Key features include 624 user I/O pins, embedded transceiver channels supporting protocols such as Gigabit Ethernet (per IEEE 802.3 clause 36 rate matching), PCI Express, Serial RapidIO, and SONET/SDH. The device also integrates TriMatrix on-chip memory, DSP blocks, and an enhanced Phase-Locked Loop (PLL) array. The 1020-FBGA package exposes the full transceiver and I/O bandwidth of the die while providing robust thermal dissipation for sustained operation. Architecturally, the EP1SGX40GF1020I6NA leverages a 1.5 V core voltage with 0.13-micron process technology typical of the Stratix GX generation. The integrated rate matcher adheres to IEEE 802.3 clause 36 for idle additions or removals, performing clock compensation only on /I2/ ordered sets (/K28.5/+ followed by /D16.2/-). This makes the part well-suited for wireline telecom and datacom line cards where deterministic clock compensation is mandatory. Typical applications include high-speed serial backplane aggregation, broadband access equipment, military/aerospace signal processing, industrial imaging systems, and ASIC prototyping. Engineers typically pair the part with Altera's Quartus II design suite for HDL synthesis, place-and-route, and timing closure. Designers selecting this FPGA should plan power-rail sequencing for the 1.5 V core and per-bank I/O supplies, allocate sufficient board area for the 1020-ball BGA, and ensure JTAG access for in-system programming and boundary-scan test.

A Field Programmable Gate Array (FPGA) is a reconfigurable semiconductor that lets engineers implement arbitrary digital logic, signal processing pipelines, and high-speed serial interfaces in a single IC. Stratix GX belongs to the broader category of programmable logic devices (PLDs), which sit between fixed-function ASICs and general-purpose microcontrollers. They are commonly chosen when designs need high pin counts, parallel DSP throughput, and multiple gigabit transceivers on the same die for protocol bridging. Key features of the EP1SGX40GF1020I8 include 41,250 typical logic elements, 624 user I/O pins, and 3,423,744 bits of embedded memory. The integrated CDR/PMA block provides embedded 8B/10B encoding and a GigE rate matcher compliant with IEEE 802.3 clause 36, while the high-speed serial interface supports protocols such as 10G Fibre Channel, SONET, POS-PHY Level 4, PCI, and double data rate (DDR) SDRAM. The device is supplied in a 1020-ball flip-chip BGA package suitable for high-density backplanes. The architecture pairs a Stratix logic fabric (LABs, TriMatrix memory blocks, and DSP blocks) with the GX transceiver block that includes transmitter, receiver, and clock-data recovery circuitry per channel. The 'I8' speed grade operating at -40 °C to +100 °C industrial temperature range places this part in the slower-speed bin of the family, trading maximum transceiver frequency for improved timing margin in environmentally harsh deployments. Typical applications include 10 Gigabit Ethernet line cards, multi-gigabit serial backplanes, SONET/SDH framer designs, and PCI Express bridge silicon. The same Stratix GX silicon is also widely adopted in test-and-measurement prototyping using the official Stratix GX Development Board. When designing with this device, ensure signal-integrity simulation of all transceiver channels before PCB layout commitment, and provide matched-length differential routing for every channel. Note that Altera/Intel recommends Quartus II design software for synthesis and place-and-route, and that the 'I8' speed grade has tighter timing margins than commercial-grade parts in the same family.

The part is built on a 1.5 V core / 0.13 µm SRAM process and combines general-purpose FPGA fabric with up to 20 full-duplex transceiver channels supporting serial rates up to 3.1875 Gbps, enabling multi-gigabit serial I/O without external PHY devices. A Field-Programmable Gate Array (FPGA) is a reprogrammable semiconductor device whose logic resources, routing, and I/O cells are configured by a user-supplied bitstream rather than fixed at fabrication. FPGAs belong to the broader category of programmable logic devices (PLDs), which sit alongside ASICs and microcontrollers in the digital IC taxonomy: FPGA -> PLD -> programmable logic -> integrated circuit -> semiconductor. Stratix GX specifically is a transceiver-centric variant of the Stratix family, optimized for serial connectivity to physical-layer devices, backplanes, and memory interfaces. Key features of the EP1SGX40GF800C5N include up to 3.432 Mbits of embedded RAM, 14 DSP blocks (approximately 56 9-bit multipliers), 24 PLLs for clock management, and 8 phase-locked clock networks. The device supports source-synchronous interfaces up to 1 Gbps and external memory interfaces including DDR SDRAM, QDR SRAM, and ZBT SRAM. Configuration is typically loaded via the EPC-series enhanced configuration devices or through JTAG. The transceiver architecture uses a hardened PCS/PMA block with built-in 8B/10B encoding/decoding, word alignment, rate-matching FIFO, and clock-data recovery, removing the need for soft logic implementation. This dramatically reduces FPGA fabric usage and improves timing closure for serial protocols. Combined with dynamic phase alignment and pre-emphasis on TX outputs, the part is suitable for driving backplane channels and direct chip-to-chip serial links. Typical applications include 10 Gbps Ethernet aggregation (using four 3.125 Gbps channels aggregated via XAUI), Serial RapidIO fabric switching, PCI Express endpoint implementations, HD-SDI video transport, and proprietary chip-to-chip serial links in storage and telecommunications equipment. The Stratix GX family was designed for protocol-rich line cards where transceiver count and protocol flexibility outweigh raw logic density. When designing with the EP1SGX40GF800C5N, plan for multi-rail power sequencing (1.5 V core, 3.3 V I/O, separate analog supply for transceivers) and reserve adequate PCB area for the FineLine BGA escape routing. Use the Quartus II design suite (Stratix GX edition) for synthesis, place-and-route, and SignalTap logic analysis; legacy projects may need migration to newer Quartus versions for tool compatibility.

The device operates from a 1.5 V core supply with auxiliary 3.3 V I/O and PLL analog supplies, and is specified over the commercial 0C to +85C junction temperature range (speed grade -7). The Stratix GX architecture combines a TriMatrix embedded memory structure with dedicated high-speed serial channels, enabling single-chip implementation of protocols such as Serial RapidIO, PCI Express, XAUI, Fibre Channel, and SONET/SDH. The integrated transceivers eliminate external PHY components, reducing board area and BOM cost for serial backplane designs. Typical applications include 10 Gbps line-card bridges, multi-gigabit serial backplane aggregators, ASIC prototyping, telecom data-path processing, and serial RapidIO switches. Engineers frequently pair this device with TI or Maxim hot-swap controllers and Micrel/Microchip Ethernet PHYs on the same line card. When designing with the EP1SGX40GF800C7N, engineers should note that the 800-BGA FineLine package requires a multilayer PCB with controlled-impedance routing for the transceiver channels. Power sequencing between the 1.5 V core and 3.3 V I/O rails must follow the datasheet Sequence A or Sequence B to prevent latch-up. The Altera Quartus II design software (now Intel Quartus Prime) is required for synthesis, place-and-route, and timing closure.

EP1SGX40GF800I5N - Stratix GX 40K LEs FPGA | Intel / Altera | 800-pin FBGA

The Intel (formerly Altera) EP1SGX40GF800I5N is a high-density Stratix GX family FPGA delivering 41,250 equivalent logic elements (LEs), 3.42 Mbits of embedded RAM, and 20 full-duplex multi-gigabit transceivers in a 800-pin FineLine BGA (FBGA) package. It operates across an industrial temperature range (-40C to +100C junction) at the -5 speed grade and is intended for high-speed serial I/O designs including backplanes, chip-to-chip links, and protocol bridging. What is a Stratix GX FPGA? A Field-Programmable Gate Array (FPGA) is a reconfigurable integrated circuit that lets designers implement arbitrary digital logic, memory blocks, and high-speed serial interfaces in a single device. Stratix GX is Intel/Altera's family that embeds dedicated multi-gigabit transceivers (MGTs) supporting protocols such as Gigabit Ethernet, PCI Express, Serial RapidIO, XAUI, and Fibre Channel up to 3.125 Gbps per channel. FPGAs sit hierarchically within programmable logic -> reconfigurable computing -> digital ICs -> semiconductors. Key features of the EP1SGX40GF800I5N include 20 transceiver channels with embedded 8B/10B encoding and clock data recovery (CDR), up to 376 user I/O pins across 11 I/O banks, dedicated DDR memory interface circuitry, and Stratix DSP blocks for high-throughput signal processing. The -5 speed grade targets higher internal clock frequencies compared to -6/-7 grades at the cost of typical internal logic performance trade-offs. Architecturally the device combines a logic fabric of adaptive logic modules (ALMs), TriMatrix embedded memory (MRAM blocks), DSP blocks, and MGT channels arranged around a high-bandwidth multi-track interconnect. Internal configuration uses SRAM cells, requiring an external configuration device such as the EPC16 or EPCS family for in-system programming. JTAG (IEEE 1149.1) supports boundary-scan test and in-circuit programming. Typical applications for the EP1SGX40GF800I5N include multi-gigabit serial backplane designs, edge routers, telecom line cards, military/aerospace signal processing, and prototyping of PCI Express endpoints. Industrial-grade temperature rating and 20 transceivers make it suitable for ruggedized communications platforms requiring high channel density. Design considerations include careful power-rail decoupling for each MGT supply (VCCA, VCCP, VCCH), matched-length differential routing on all serial channels, and thermal management via the exposed-die FBGA substrate. FPGA bitstream encryption via AES is recommended for production deployments.

EP1SGX40GF800I7

EP1SGX40GF800I7 - Stratix GX FPGA, 41.25K LE, 20 SERDES | Altera

The Altera (now Intel) EP1SGX40GF800I7 is a member of the Stratix GX FPGA family that integrates up to 20 high-speed serial transceivers (SERDES) operating up to 3.125 Gbps, with 41,250 logic elements (LE), 3,423,744 bits of embedded RAM, and 624 hardware multipliers (18x18), housed in an 800-pin FineLine BGA package. It targets high-bandwidth serial-interface applications including backplane transceivers, multi-gigabit serial links, and protocol-bridging designs. The 'I' speed grade and '7' device grade correspond to the industrial temperature range and -7 speed bin respectively. An FPGA (Field-Programmable Gate Array) is a programmable logic device containing configurable logic blocks (LBs), programmable interconnects, embedded memory, and increasingly hard IP cores such as transceivers and DSP blocks. FPGAs sit between microcontrollers and ASICs in the design spectrum: more flexible than ASICs and far more parallel than microcontrollers. The Stratix GX family specifically extends the general-purpose Stratix architecture with embedded multi-gigabit transceivers (MGTs), making it suitable for serial connectivity, chip-to-chip links, and protocol bridging without external PHY ICs. Key features of the EP1SGX40GF800I7 include 20 full-duplex SERDES channels at up to 3.125 Gbps, dedicated 8B/10B encoder/decoder hardware, on-chip clock data recovery (CDR) per channel, and support for protocols including PCI Express, Gigabit Ethernet, Serial RapidIO, XAUI, and Fibre Channel. The device embeds TriMatrix memory architecture (M512, M4K, M-RAM blocks) totaling 3.4 Mbits, and provides up to 12 PLLs for clock management across logic and transceiver domains. Architecturally, the Stratix GX combines a logic-rich fabric with hardened multi-gigabit transceivers, allowing designers to implement protocol stacks in programmable logic while offloading physical-layer (PHY) functions to silicon. The 800-pin FineLine BGA provides sufficient I/O count for both the high-speed serial lanes and wide parallel LVDS/LVTTL interfaces. Industrial-grade screening (-40C to +100C operating junction) ensures deployment in harsh environments such as telecom outdoor units, industrial backplanes, and military/aerospace prototypes. Typical applications include multi-gigabit backplane transceivers, telecom line cards with XAUI or Serial RapidIO interconnect, PCI Express endpoint and root complex implementations, high-speed serial bridging (e.g., Fibre Channel to Ethernet), and high-performance DSP front-ends. The 3.125 Gbps per lane capability also makes it suitable for proprietary chip-to-chip links and test/measurement backplanes. When designing with this device, allocate adequate PCB layers (typically 8-12) and controlled-impedance routing for the SERDES lanes; Altera application notes specify 100-ohm differential impedance and length matching within 150 mils for transceiver signals. Use the Quartus II design software (Altera/Intel FPGA design suite) for synthesis, place-and-route, and timing closure; the design flow must include transceiver wizard configuration for protocol-specific PHY parameters.

The Altera (Intel) EP20K1000CB652C7NJ is a high-density APEX 20KC family FPGA delivering 1,000,000 system gates and 38,400 logic elements in a 652-pin FineLine BGA (FCBGA) package. Built on a 0.15-micron all-layer copper-metal process, the device integrates look-up table (LUT) logic with embedded system blocks (ESBs) for on-chip memory and dedicated arithmetic, supporting system clocks up to 375.94 MHz at 1.8V core supply. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to perform a wide range of digital logic functions. FPGAs sit hierarchically within programmable logic devices (PLDs), which themselves belong to the broader digital IC and ASIC-replacement category. Modern FPGAs combine configurable logic blocks (CLBs), programmable interconnect, embedded memory, multipliers/DSP slices, and high-speed transceivers, enabling hardware-level parallelism far beyond what general-purpose microcontrollers or DSPs can achieve at comparable cost for a given workload. Key features of the EP20K1000CB652C7NJ include 488 user I/O pins, 327,680 bits of embedded memory, four phase-locked loops (PLLs) for clock management, MultiCore embedded memory architecture, and pin compatibility with the APEX 20KE family for design reuse. The 652-pin FCBGA package supports high-density board designs with controlled-impedance signal integrity for parallel and serial high-speed interfaces. Architecturally, the APEX 20KC combines LUT-based logic with embedded system blocks that can each implement dual-port RAM, ROM, or content-addressable memory. The 0.15-micron copper interconnect reduces propagation delay and dynamic power versus the aluminum-process APEX 20K, while remaining pin-compatible so existing 20KE boards accept the 20KC device without re-layout. Typical applications include high-speed telecom backplanes, parallel DSP pipelines, ASIC prototyping, industrial imaging and video processing, and military/aerospace signal processing. The 488 I/O and abundant internal memory also make this part suitable for legacy system sustainment and form-fit-function replacement programs. When designing with this part, engineers must plan for the 1.8V core supply and provide adequate decoupling around the BGA footprint. JTAG configuration via the ByteBlaster or MasterBlaster cable is supported, but Quartus II software (legacy Altera IDE) is required for synthesis, place-and-route, and bitstream generation. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes beyond the manufacturer datasheet summary, helping procurement and engineering teams evaluate the EP20K1000CB652C7NJ for both new designs and legacy sustainment programs.

The Intel (formerly Altera) EP20K1000CF672C7 is a high-density APEX 20KC family Field-Programmable Gate Array (FPGA) delivering approximately 1,000,000 system gates and 38,400 logic elements, fabricated on a 0.15 µm all-layer copper-metal CMOS process. It is offered in a 672-ball FC-FBGA package with 488 user I/Os (some sources list 508 user I/Os) and operates from a 1.8 V core supply with a maximum internal clock frequency around 375.94 MHz and a propagation delay of approximately 1.6 ns. An FPGA is a programmable logic device (PLD) that integrates configurable logic blocks (LEs), embedded memory (CAM/ROM/RAM), routing channels, and I/O elements on a single die. Within the programmable-logic taxonomy, FPGAs sit above simple PLDs (SPLDs/CPLDs) and below ASICs in NRE cost, and APEX 20KC represents Intel/Altera's high-density, multi-core, embedded-memory programmable logic family introduced in the early 2000s. The APEX 20KC family supports up to 1 M gates, embedded CAM blocks, LVDS I/O, and 1.8 V low-voltage operation. Key features of the EP20K1000CF672C7 include 38400 logic cells/elements, 1 M system gates, embedded array blocks (EABs) for memory and DSP-style functions, four phase-locked loops (PLLs) for clock management, multi-voltage I/O standards (LVTTL, LVCMOS, PCI, LVDS, GTL+, SSTL-2/3, HSTL), in-system programmability via the passive serial, JTAG (IEEE 1149.1), and Altera Fast Passive Parallel configuration interfaces, and a JunctionLink technology that doubles performance versus the prior APEX 20KE generation. The C7 speed grade offers the fastest timing in the family. The 0.15 µm copper-metal process permits 35% faster design performance than APEX 20KE devices at lower dynamic power per toggle. Each EAB block provides up to 4096 bits of dual-port or single-port RAM plus content-addressable memory functionality for high-speed table lookup. The 672-pin FC-FBGA package (45 × 45 mm, 1.27 mm ball pitch) supports the largest I/O count in the APEX 20KC family and is required when 488/508 user I/O pins are needed. Typical applications include telecommunications line cards, ASIC prototyping and emulation, high-speed data path processing, glue logic for DSP/microprocessor-based systems, industrial machine control, and military/aerospace embedded computing. The device is well-suited to designs requiring hundreds of I/O with moderate-to-high logic density. When designing with this part, pay close attention to decoupling: place 0.1 µF and 0.01 µF ceramics on every VCCINT/VCCIO pin with a 4-layer PCB at minimum. Because this is an obsolete Intel/Altera product, lead-time and second-source strategies should be evaluated up front. The C7 speed grade is the fastest bin; slower C8/C9 bins exist for cost reduction.

EP20K1000CF672C7ES - APEX 20KC FPGA 1M Gates 672-FBGA | Altera

The Altera (Intel Programmable Solutions Group) EP20K1000CF672C7ES is a high-density APEX 20KC family FPGA integrating 1,000,000 system gates and 38,400 logic elements in a 672-pin Fine-pitch Chip-scale Ball Grid Array (FC-FBGA) package. Built on a 0.15 µm CMOS process, it operates from a 1.8 V core supply and is rated for commercial temperature grade with typical internal performance up to 375.94 MHz. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing programmable logic blocks, interconnect, and I/O that engineers configure after manufacturing to implement custom digital circuits, DSP pipelines, or processor subsystems. FPGAs occupy the broad product hierarchy: programmable logic -> logic IC -> integrated circuit -> semiconductor. The APEX 20KC family extended the original APEX architecture with MultiVolt I/O support, embedded system blocks (ESBs) for dual-port RAM and CAM, and FastTrack interconnect, making it suitable for high-throughput glue logic and interface bridging. Key features include 38400 logic cells, dedicated embedded memory blocks, 4 PLLs for clock management, and a high-pin-count FC-FBGA package providing ample user I/O for parallel bus, memory, and high-speed interface applications. The device supports in-system programmability via IEEE 1149.1 (JTAG) and configuration via passive serial, passive parallel asynchronous, and passive parallel synchronous modes. The APEX 20KC architecture combines look-up-table-based logic elements with embedded array blocks (EABs) that can be configured as RAM, ROM, or content-addressable memory. This hybrid LUT/EAB structure allows trade-offs between fine-grained logic and dense storage on a single die. The 672-pin FC-FBGA package supports hundreds of user I/O pins, enabling parallel external memory interfaces (DDR, QDR, ZBT) and multi-channel serializer/deserializer connections at LVTTL, LVCMOS, SSTL, and HSTL signaling levels. Typical applications include telecommunications line cards, ASIC prototyping, image and video processing pipelines, industrial control and factory automation, military and avionics subsystems, and high-performance DSP co-processing. The 1M-gate density is well-matched to mid-complexity designs where full-custom ASIC NRE costs are not justified, or where post-production design changes are required. When designing with this part, ensure the 1.8 V core supply is decoupled close to the package balls, follow Altera's multi-voltage I/O sequencing recommendations, and plan configuration PROM or JTAG chain topology before PCB layout. The -7 speed grade indicates typical Fmax of 250 MHz for registered designs.

It is fabricated on a 0.15 µm CMOS process and supports core voltages of 1.71 V to 1.89 V with multi-voltage I/O standards. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit built from an array of configurable logic blocks (CLBs), programmable interconnect, and embedded memory and DSP resources that can be re-programmed after manufacturing to implement arbitrary digital logic. FPGAs sit hierarchically between ASICs (application-specific, high-NRE fixed function) and microcontrollers (software-driven, fixed silicon), offering hardware-level parallelism for data-path heavy applications. APEX 20KC specifically targets high-volume communications, networking, and DSP applications with embedded dual-port RAM. The EP20K1000CF672C7GZ supports up to 4 PLLs, embedded array blocks (EABs) of 2,048 bits each, and LVDS, LVTTL, LVCMOS, SSTL, and GTL+ I/O standards. The 672-pin FBGA package uses a 27 mm × 27 mm body with 1.27 mm pitch, enabling dense board placement. The "C7" speed grade corresponds to a commercial temperature range of 0°C to +85°C with a 7 ns pin-to-pin logic delay. Architecturally, the APEX 20KC family integrates Logic Array Blocks (LABs) for fine-grained logic and Embedded Array Blocks (EABs) for memory and product-term functions. The MultiVolt I/O interface allows 1.8 V, 2.5 V, 3.3 V, and 5 V interfacing without external level shifters, simplifying mixed-voltage system design. Typical applications include high-speed telecommunications line cards, network switches and routers, DSP co-processing engines, high-density glue logic replacement, and protocol bridging in legacy industrial systems. The 508 user I/O count and 327 Kb of embedded RAM also suit video processing and image pre-processing pipelines. When designing with the EP20K1000CF672C7GZ, pay careful attention to power sequencing: the core supply must reach 1.89 V before I/O supplies ramp to avoid latch-up. Use the Quartus II design suite (legacy Altera software) for synthesis, place-and-route, and timing closure. Decouple every VCCINT and VCCIO pin with 0.1 µF X7R ceramic capacitors placed within 5 mm of the ball. This page synthesizes distributor pricing, drop-in same-package alternatives, comparison parameters, and practical design guidance curated for the EP20K1000CF672C7GZ - information that complements the official datasheet with engineer-facing selection context.

EP20K1000CF672C8 - APEX 20KC FPGA 1M Gates 672-BGA | Altera
EP20K1000CF672C8

EP20K1000CF672C8 - APEX 20KC FPGA 1M Gates 672-BGA | Altera

The Altera (Intel) EP20K1000CF672C8 is a member of the APEX 20KC family of Field-Programmable Gate Arrays (FPGAs), delivering up to 1,000,000 system gates, 38,400 logic elements, and 327,680 bits of embedded RAM in a 672-ball FineLine BGA package. The device exposes 488 user I/Os (some sources cite 508 I/O count) and is fabricated on a 0.15-micrometer all-layer copper CMOS process, providing approximately 35% faster design performance than the original APEX 20KE generation. The part is rated for the commercial operating temperature range of 0C to 85C. An FPGA (Field-Programmable Gate Array) is a semiconductor device whose logic fabric, routing, and I/O behavior are defined by a user-supplied configuration bitstream rather than by hard-wired mask layers. FPGAs sit within the broader hierarchy of programmable logic devices (PLD -> CPLD -> FPGA -> SoC FPGA), bridging the gap between fixed-function ASICs and software-driven microcontrollers. The APEX 20KC family in particular targets high-density, parallel datapath designs where on-chip memory and a large number of user I/Os are required. Key features of the EP20K1000CF672C8 include MultiCore architecture with embedded CAM blocks, support for LVDS, LVTTL, LVCMOS, SSTL, and GTL+ I/O standards, four phase-locked loops (PLLs) for clock management, and built-in boundary-scan (IEEE 1149.1 JTAG) support. The device supports in-system programmability via the Fast Passive Parallel (FPP) or Passive Serial (PS) configuration modes using Altera/Quartus configuration bitstreams, with EPC configuration devices or a microprocessor host. The 672-ball FineLine BGA package is built around a 45 x 45 mm substrate with a 1.27 mm ball pitch. The 0.15-micrometer copper process enables a core voltage around 1.8 V, with the multi-voltage I/O banks supporting reference voltages appropriate to the standard in use. Designers can apply the device across wired telecom backplanes, industrial control planes, video processing pipelines, ASIC prototyping, and high-speed instrumentation front-ends. When designing with the EP20K1000CF672C8, ensure proper power sequencing between VCCINT (core) and VCCIO (I/O) rails. Decoupling must follow Altera's recommended 0.1 uF + bulk capacitor topology adjacent to each power pin, and the JTAG chain must be terminated to avoid configuration failures. The APEX 20KC family is now legacy - long-term designs should consider migration to Stratix or Cyclone families for active lifecycle support. This page synthesizes distributor pricing, drop-in same-brand alternatives, and legacy FPGA design notes that the manufacturer datasheet alone does not consolidate.
