EP20K100QC208-1 - APEX 20K FPGA 100K Gates 208-Pin PQFP | Altera
EP20K100QC208-1

EP20K100QC208-1 - APEX 20K FPGA 100K Gates 208-Pin PQFP | Altera

The Altera EP20K100QC208-1 is an APEX 20K family Field-Programmable Gate Array (FPGA) with 100K equivalent gates, 4160 logic elements, and a maximum core frequency of 250 MHz, housed in a 208-pin Plastic Quad Flat Pack (PQFP) tray package. It is manufactured on a 0.22 µm (some sources cite 0.15 µm all-layer copper) CMOS process and operates from a 2.5 V core supply. The device integrates an embedded array block architecture that pairs look-up-table (LUT) logic with dedicated memory blocks, enabling efficient implementation of wide datapaths, FIFOs, and on-chip RAM. The PQFP-208 pinout exposes up to 159 user I/Os, providing generous connectivity for parallel buses and standard digital interfaces. An FPGA (Field-Programmable Gate Array) is a programmable logic device that combines configurable logic blocks (CLBs), programmable interconnects, and I/O cells on a single silicon die. In the broader taxonomy, an FPGA sits inside the programmable logic category alongside CPLDs, and above that the integrated circuit (IC) hierarchy. APEX 20K devices are SRAM-based, meaning configuration data must be loaded from an external PROM or microcontroller at every power-up, which makes them reprogrammable in-system but volatile. The "20K" prefix in the family name indicates the use of MegaLAB structures that combine multiple Logic Array Blocks (LABs) for higher density. Key features of the EP20K100QC208-1 include 26,624 typical gates, 4,160 logic elements, 53,248 bits of embedded RAM distributed across embedded array blocks, 4 phase-locked loops (PLLs) for clock synthesis, and multi-standard I/O support including LVTTL, LVCMOS, PCI, and GTL+. The -1 speed grade corresponds to the slowest of the three available grades (-1, -2, -3) for the APEX 20K family, offering a tPD of about 1.6 ns as cited in third-party datasheet summaries. The 2.5 V core is supplemented by separate VCCIO banks that can be powered to interface with 3.3 V, 2.5 V, or 1.8 V logic families. Architecturally, the EP20K100QC208-1 is built around MegaLAB columns that group 16 LABs and one embedded system block (ESB). Each ESB can be configured as either dual-port RAM, single-port RAM, ROM, or product-term logic, giving designers a flexible mix of LUT-based and product-term-based resources on the same die. The four PLLs support clock multiplication, division, phase shifting, and external feedback, which is essential for source-synchronous interfaces and frequency synthesis. Typical applications for the EP20K100QC208-1 include telecommunication line cards, industrial control and factory automation, medical imaging front-ends, networking switches and routers, and legacy PCI bus bridges. Designers choose APEX 20K for mid-density glue-logic consolidation, bus-interface bridging, or prototyping designs destined for Altera's higher-density Stratix or Cyclone families. When designing with this part, note that PQFP-208 has a relatively large 28 x 28 mm footprint and 0.5 mm lead pitch, requiring a multilayer PCB with sufficient via density. The SRAM-based configuration needs a serial or parallel configuration PROM such as the EPC2 or EPC16, and the JTAG chain must include the EPC device for in-system programming support.

EP20K100QC208-1N

EP20K100QC208-1N - 100K APEX 20K FPGA, 208-PQFP | Intel

The Intel EP20K100QC208-1N is a member of the APEX 20K family of programmable logic devices (PLDs), delivering 100K typical gates and 4,160 logic elements in a 208-pin Plastic Quad Flat Pack (PQFP) package with 0.5 mm terminal pitch. The device combines fine-grain logic, embedded system blocks (ESBs) for memory, and high-speed I/O in a single chip fabricated on a 0.22 µm CMOS process. A speed grade of -1 places it among the highest-performance members of the APEX 20K family, supporting up to 250 MHz internal operation. A programmable logic device (PLD) is a semiconductor whose logic function is defined by user-loaded configuration data rather than by factory mask programming. Within that hierarchy, a field-programmable gate array (FPGA) such as the APEX 20K contains an array of configurable logic blocks (CLBs), routing resources, and I/O cells. The APEX 20K family further introduced embedded system blocks that provide dual-port RAM, content-addressable memory, and product-term logic, blurring the line between FPGA and complex PLD (CPLD). The 'QC208' suffix denotes the 208-pin PQFP package, while '-1N' indicates the -1 speed grade in a commercial 0–85 °C temperature range. Key features include 159 usable user I/Os, four dedicated fast inputs for high-fanout clocking, on-chip phase-locked loops for clock multiplication and deskew, and JTAG-based in-system programmability (ISP). The 2.5 V core supply (VCCINT) is supported by a multi-voltage I/O ring that can be configured for 2.5 V, 3.3 V, or 5 V interfaces using separate VCCIO banks. Embedded system blocks deliver up to 53 Kbits of dual-port RAM while remaining bit-stream-compatible with the APEX 20KE generation. Architecturally, the EP20K100 partitions into MegaLAB structures that each contain 16 logic elements and one ESB. Carry-chain and cascade-chain interconnects accelerate arithmetic and wide fan-in functions, while MultiTrack routing provides predictable timing closure for high-speed designs. The device is in-system programmable through the IEEE 1149.1 (JTAG) port, supporting background reconfiguration without halting the application. Typical applications include telecommunications line cards, industrial control and machine vision, military and avionics signal processing, and prototyping of ASIC functionality. The 208-pin PQFP package is hand-solderable and socket-compatible, making the part a popular choice for legacy designs and lab validation. The EP20K100QC208-1N is also commonly used as a glue-logic replacement for multiple 74-series TTL devices. When designing with this device, verify the Quartus or MAX+PLUS II toolchain supports the targeted density and that JTAG chain provisioning is allocated on the board. The 208-pin PQFP offers fewer I/Os than the BGA-652 variant of the same silicon, so designers migrating between packages must re-validate pin assignments. For new designs, Intel recommends the Cyclone series instead. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, including source-traced specifications, EOL-aware cross references, and AEO-optimized answers to the questions procurement and design engineers actually ask.

EP20K100QC208-2

EP20K100QC208-2 APEX-20K FPGA 263K Gate 4160 LE | Altera

The Altera EP20K100QC208-2 is a 263,000-gate APEX-20K Field Programmable Gate Array (FPGA) containing 4,160 logic elements, 416 LABs, 53,248 RAM bits, and 159 user I/Os, supplied in a 208-pin BFQFP/PQFP surface-mount package and rated for the 0 °C to 85 °C commercial operating range. Mouser and DigiKey list the device as an APEX-20K programmable logic device with 4,160 logic elements/cells and 159 I/O pins, while Rochester Electronics supplies the legacy Altera inventory. An FPGA is an integrated circuit whose logic blocks and interconnect can be reconfigured after manufacturing, allowing hardware functions to be changed in the field or during development. The APEX-20K family occupies the programmable-logic space between CPLDs and larger array FPGAs: it combines moderate logic density, embedded memory, and wide I/O for applications such as communication bridging, industrial control, video processing, and test equipment. This EP20K100QC208-2 is an early-2000s Altera architecture now handled mainly through legacy-stock distributors. The key features of EP20K100QC208-2 include 263,000 typical gates, 4160 logic elements, 416 LABs/CLBs, 53,248 total RAM bits, and 159 user I/O pins. The 208-lead BFQFP package enables dense board layouts with a square 28x28 mm body and gull-wing terminals. The -2 speed grade is the mainstream mid-speed ordering option in the original APEX-20K QC208 group, widely used in legacy telecom, industrial, and measurement platforms where the design is already fitted to this exact footprint. The APEX-20K architecture uses a programmable logic core with JTAG-based in-system configuration and supports external configuration devices. The logic elements are grouped in LABs, giving a predictable route from HDL synthesis to place-and-route. With 159 I/Os, the device can bridge processor buses, memory interfaces, and peripheral logic, while the embedded RAM bits are useful for FIFOs and small frame buffers without external SRAM. Typical applications include legacy telecommunication line-card glue logic, industrial control I/O expansion, broadcast video format bridging, test-and-measurement instrument logic, and educational FPGA prototyping. Because this is an older programmable-logic device, most current demand is for maintaining existing production systems, replacing failed boards, or supporting installed equipment rather than for new high-volume designs. Designers must verify the exact VCC specification from the authoritative APEX-20K datasheet; one distributor listing on the 2026-09-07 search shows 1.71 V to 1.89 V, while Altera ordering conventions for a non-E APEX-20K often imply a 2.5 V family device. Use adequate VCC decoupling and confirm the configuration-device interface before committing a repair or bridged design. This page aggregates distributor availability, package data, drop-in QC208 alternatives, and practical legacy-design notes not found in a plain manufacturer datasheet, helping engineers and buyers source this obsolete FPGA with more confidence.

EP20K100QC208-2X - APEX 20KE 100K Gates FPGA 208PQFP | Intel
EP20K100QC208-2X

EP20K100QC208-2X - APEX 20KE 100K Gates FPGA 208PQFP | Intel

The Intel (formerly Altera) EP20K100QC208-2X is a member of the APEX 20KE programmable logic device family that delivers 100,000 system gates, 4,160 logic elements, and 53,248 bits of embedded memory in a 208-pin Power QFP (PQFP/BQFP) package. The device operates from a 2.375 V to 2.625 V core supply (1.8 V I/O standard variant) and supports 159 user I/O with multi-voltage I/O capability, making it suitable for mixed-voltage system designs. The "QC208" package suffix denotes the 208-pin plastic QFP form factor, while "-2X" indicates the speed grade and lead-free / extended temperature option. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the user can re-program after manufacture to implement arbitrary digital logic. The APEX 20KE family pioneered the MultiCore architecture, integrating look-up table (LUT) logic, product-term logic, and embedded system blocks (ESBs) on a single die - this combination enabled SOPC (System-on-a-Programmable-Chip) integration before that term became mainstream. FPGAs sit hierarchically under programmable logic devices (PLDs) and above fixed-function ASICs in the digital design taxonomy. Key features of the EP20K100QC208-2X include the MultiCore architecture combining LUT and product-term logic, 53248 bits of embedded SRAM distributed across embedded system blocks, four Phase-Locked Loops (PLLs) for clock management, and LVDS-compatible I/O support at 1.8 V. The 0.22-micron CMOS process node and 2.5 V core supply deliver a balance of density and power efficiency for the era. With 159 user I/O and a 200 MHz internal performance target, the device bridges moderate-density logic integration with high pin-count board-level connectivity. Typical applications include telecommunications line-card interface logic, industrial control glue logic, peripheral bridging (PCI to local bus), custom DSP co-processors, and pre-silicon prototyping for ASIC designs. Engineers often deploy the APEX 20KE in legacy systems where the part has already been qualified into long-lifecycle equipment. The 208 PQFP form factor also supports hand-soldering and inspection workflows that fine-pitch BGA packages cannot accommodate, which matters for low-volume or ruggedized programs. When designing with this device, use the Altera Quartus II (MAX+PLUS II for legacy flows) design toolchain for synthesis, place-and-route, and bitstream generation. Pay close attention to I/O bank voltage grouping and supply decoupling - the 2.5 V core and multiple I/O voltages each require their own bypass network. The device is now classified as a legacy / mature product, so confirm long-term supply with the manufacturer before committing to new designs. This page synthesizes distributor pricing, package cross-reference, and practical design considerations drawn from the original APEX 20KE datasheet family - context that manufacturer datasheets alone do not aggregate into a single comparison view.

EP20K100QC208-3N - APEX 20K FPGA, 100K Gates | Intel
EP20K100QC208-3N

EP20K100QC208-3N - APEX 20K FPGA, 100K Gates | Intel

The Intel (Altera) EP20K100QC208-3N is an APEX 20K programmable logic device providing 100K system gates, 4,160 logic elements/cells, and 159 user I/O pins in a 208-pin QFP package. It is part of the Altera APEX 20K family, operating from a 2.5 V core supply and offering a typical clock-performance class of 167 MHz according to Intel/Altera distributor summary data. What is an FPGA/CPLD programmable logic device? An FPGA, or field-programmable gate array, is an integrated circuit containing programmable logic blocks and programmable interconnects that can be configured after manufacturing. CPLD, or complex programmable logic device, is a denser programmable logic architecture often used in glue logic and control applications. The APEX 20K family occupies a hybrid position in this hierarchy, providing gate-array-like densities with programmable logic elements, embedded memory, and I/O flexibility. In a system hierarchy, this part sits between small CPLDs, such as MAX 7000 devices, and large transceiver-based FPGAs, giving designers a medium-density programmable-logic solution for parallel processing and bus interfacing. Key features include 100K gates, 4,160 logic cells, 159 user I/Os, 208 terminals with gull-wing construction, and a 2.5 V core supply. The QFP package code is FQFP with a square body, making it well suited for through-board-level integration on traditional surface-mount assembly lines. The N suffix in the ordering code indicates the lead-free device version, an important factor for RoHS-sensitive production environments. This device supports the APEX 20K architecture, which combines look-up table logic, product-term macrocells, and ESB embedded-system blocks. Technical depth for this part comes from the APEX 20K family architecture and its 0.22 um fabrication process. The device is listed as a LOADABLE PLD by distribution parametric systems, with terminal form of gull wing and package shape square. As a -3 speed grade, it sits below the faster -1 and -2 speed-bin variants in the same package family. Typical performance of 167 MHz in the APEX 20K family gives the EP20K100QC208-3N enough headroom for many communication-bridge, industrial-control, and display-interface applications, although exact achievable fMAX depends on the design, routing, I/O loading, and timing constraints. EP20K100QC208-3N is applicable in telecommunications line-card termination, networking protocol bridging, industrial control boards, test instrumentation, and embedded video/image capture paths where medium-density programmable logic with 159 I/Os is sufficient. Because it has no high-speed serial transceivers, it is most appropriate for parallel bus logic, address decoding, state-machine control, data buffering, and interface adaptation. The 2.5 V core and QFP package allow straightforward power-plane design and conventional PCB fan-out. A key design consideration is configuration memory: APEX 20K devices are SRAM-based and require an external configuration EPROM or download cable at power-up. Use an Altera EPC2 or EPC16 configuration device, or a JTAG-based configuration controller, and confirm that the configuration voltage and I/O-bank voltages match the surrounding system. The -3N lead-free finish should be reflected in the solder profile used during board assembly. This page synthesizes distributor listings, package attributes, drop-in speed-grade alternatives, and practical design notes for the EP20K100QC208-3N. It adds information-gain value beyond a bare datasheet by consolidating live availability, cross-reference candidates, and selection guidance in one structured format.

EP20K100QC240-1

EP20K100QC240-1 - APEX 20K FPGA 100K Gates 240-PQFP | Intel

The Intel EP20K100QC240-1 is a member of the APEX 20K family of Field-Programmable Gate Arrays (FPGAs), integrating 100,000 typical gates and 4,160 logic elements (LEs) into a 240-pin Plastic Quad Flat Pack (PQFP) surface-mount package. Built on a 0.22 µm CMOS process with a 2.5 V core supply, it delivers a maximum internal clock frequency of 250 MHz and supports 189 user I/O pins, making it suitable for high-density glue-logic, bus-interface, and DSP pre-processing applications in telecom, industrial, and embedded systems. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that allows designers to configure digital logic blocks and interconnect after manufacture. Within the broader taxonomy, an FPGA sits between a CPLD (Complex Programmable Logic Device) and an ASIC (Application-Specific Integrated Circuit): more flexible than an ASIC and higher density than a CPLD. The APEX 20K series introduced embedded dual-port RAM blocks and a MultiCore architecture combining look-up tables (LUTs) with product-term logic, allowing a single device to replace discrete SRAM, ROM, and glue logic on legacy system boards. Key features of the EP20K100QC240-1 include 4,160 logic elements, 53,248 RAM bits, 189 maximum user I/O, a -1 speed grade targeting 250 MHz Fmax, JTAG-based IEEE 1149.1 boundary-scan support, and in-system programmability via the Altera (now Intel) Quartus and MAX+PLUS II toolchains. The 2.5 V core with 3.3 V-tolerant I/O simplifies interfacing to legacy 5 V-tolerant bus transceivers through external series resistors. The 240-pin PQFP with 0.5 mm pitch supports hand-soldering for prototypes and standard surface-mount assembly for production volumes. Typical applications include PCI bridge designs, telecom line-card glue logic, network router backplane interfaces, industrial motor-control state machines, and migration paths for legacy APEX 20K prototypes still in field service. With a 0 to 85 °C commercial operating-temperature range, this part targets benign-environment embedded systems rather than automotive or extended-industrial deployments. When designing with this device, plan JTAG chain access early and verify Quartus II version compatibility - newer Intel Quartus releases have dropped APEX 20K device support. For new designs, evaluate Cyclone IV or MAX II as the modern equivalent family, since APEX 20K silicon is mature and approaching end-of-life availability through authorized distributors.

EP20K100QC240-1XV

EP20K100QC240-1XV - APEX 20K 100K-Gate FPGA, 240-PQFP | Intel / Altera

The Intel (formerly Altera) EP20K100QC240-1XV is a member of the APEX 20K family of programmable logic devices (PLDs) featuring 100,000 system gates, 4,160 logic elements (cells), and 53,248 bits of embedded memory. Housed in a 240-pin PQFP (Plastic Quad Flat Pack) package, this device combines LUT-based logic, product-term logic, and embedded memory blocks on a single die to deliver system-on-a-programmable-chip (SOPC) integration. It operates at a nominal 2.5V core supply (range 2.375V to 2.625V) with 5V-tolerant I/O and supports up to 189 user I/O pins, of which 4 are dedicated inputs. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be electrically programmed to implement any digital logic function. Within the broader hierarchy, the EP20K100QC240-1XV sits as a PLD > FPGA > SRAM-based reprogrammable FPGA > fine-grained LUT architecture device. APEX 20K extends the classic LUT-plus-product-term hybrid approach pioneered by Altera, allowing register-intensive datapaths, finite-state machines, and moderate-density memory blocks to coexist on one chip without external glue logic. The MultiCore architecture integrates LUT logic for register-intensive functions, product-term logic for wide combinatorial decode, and embedded system blocks (ESBs) for on-chip RAM or ROM. Key features of the EP20K100QC240-1XV include a propagation delay of approximately 2.5 ns and an internal core frequency of up to 250 MHz. The device includes 4 phase-locked loops (PLLs) for clock management and skew control, supports in-system programming via JTAG, and provides configurable I/O standards. The 240-pin PQFP body measures 32 mm x 32 mm with a 0.5 mm lead pitch and gull-wing terminations suitable for surface mounting. Industrial temperature variants (suffix-less) span 0C to +85C. The APEX 20K family was the industry's first PLD family to integrate SOPC capability, blurring the line between traditional FPGAs and system-on-chip solutions. By embedding dedicated arithmetic blocks, memory, and PLLs alongside general-purpose logic, the EP20K100 enables designers to consolidate what previously required a CPLD plus a separate SRAM plus clock buffers onto a single chip, reducing board area, BOM count, and design complexity. Typical applications include telecommunications line cards, industrial control and factory automation backplanes, DSP pre/post-processing front-ends, PCI bus bridges, and custom peripheral controllers for embedded systems. The 240-pin PQFP footprint suits legacy through-hole-style reflow profiles, making this part a drop-in solution when modern BGA-only successors cannot be retrofitted onto an existing PCB. When designing with this part, ensure the configuration device (EPC or enhanced) is sized for the bitstream and that JTAG chain integrity is preserved across multiple EP20K devices. Note that the -1XV suffix denotes the extended-temperature / speed-grade 1 variant; verify tpd and fMAX against the timing model in the Altera APEX 20K datasheet before board bring-up. This page synthesizes distributor pricing, lifecycle status, package-level drop-in alternatives from the APEX 20K family, and practical design notes not consolidated in the manufacturer datasheet - offering information gain beyond the original Altera documentation.

EP20K100QC240-2

EP20K100QC240-2 FPGA - 4160 LE, 189 IO | Altera

The Altera EP20K100QC240-2 is an APEX-20K field-programmable gate array (FPGA) containing 4,160 logic elements, 189 user I/O pins, and 53,248 RAM bits, with a 100K typical gate count and 263K maximum system gates. It operates from a nominal 2.5 V core supply and is supplied in a 240-pin BFQFP (plastic quad flat pack) package with 0.5 mm terminal pitch. This is the -2 speed grade variant of the EP20K100 QC240 family. An FPGA is a programmable logic device whose logic blocks and routing can be configured after manufacturing by loading a bitstream. In the IC hierarchy FPGA -> programmable logic device -> integrated circuit, the EP20K100 belongs to Altera's APEX-20K family, which combined look-up-table logic and embedded memory to serve mid-density digital designs. Configuration bitstreams are held in SRAM cells and must be loaded at power-up unless a configuration device or controller manages it. Key differentiators of the EP20K100QC240-2 include 4,160 logic elements, 189 user I/O, 53,248 RAM bits, 2.5 V core operation, and 240-pin BFQFP packaging. Distributor snippets identify 200 MHz internal operation, 3 ns propagation delay, and CMOS 0.22 µm process technology. These features suit designs that need more I/O and memory than a small CPLD but do not require the density of a modern large FPGA. The APEX-20K architecture uses a hierarchical interconnect scheme with LABs, embedded system blocks, and fasttrack routing. The EP20K100 variant contains 416 LAB/CLB blocks feeding 4,160 logic elements. The 240-pin package exposes 189 user I/O pins, leaving the remaining pins for power, configuration, and JTAG. Because this is an older part family, design entry is handled by the Altera/Quartus tool flow and the device is configured through Jam/STAPL or passive serial methods. Typical applications include networking equipment, industrial controllers, test-and-measurement front ends, and video bridging. The 189 I/O count can connect to multiple memory buses, data converters, or backplane interfaces; the 53,248 RAM bits provide small FIFOs and register files without external SRAM. The 2.5 V core allows operation in classic low-voltage boards. When designing with EP20K100QC240-2, remember that the 0°C to 85°C commercial temperature range constrains environmental use, and that the 2.375 V to 2.625 V core supply should be clean and well decoupled. I/O standards and VCCIO connections must match the external bus levels; verify these against the APEX-20K datasheet before layout.

EP20K100QC240-3 - 189 I/O APEX-20K FPGA | Altera
EP20K100QC240-3

EP20K100QC240-3 - 189 I/O APEX-20K FPGA | Altera

The Altera EP20K100QC240-3 is an APEX-20K family field-programmable gate array (FPGA) with 4,160 logic elements, 189 user I/O pins, and 53,248 RAM bits, supplied in a 240-pin BFQFP package. It belongs to the 100K-gate-class APEX 20K family and is listed by DigiKey, Mouser, and Octopart with the speed-grade -3 designation. An FPGA is an integrated circuit whose logic fabric can be configured after manufacturing using a hardware description language and a bitstream. The FPGA sits above simple programmable logic devices (PLDs) in capacity and below structured ASICs in cost at high volume; it is the dominant product type for medium-density digital logic where time-to-market and reconfigurability matter. The EP20K100QC240-3 occupies that middle band: enough logic for bus interfaces and state machines, but not so many resources that a high-end FPGA is needed. Key specifications for the EP20K100QC240-3 include 4,160 logic elements, 189 user I/O pins, 53,248 RAM bits, and a typical gate count of 263,000. The core supply voltage is 2.5 V, the technology process is listed as 0.22 um, and the commercial temperature range is 0 to +85 °C. The package is a 240-pin BFQFP with gull-wing surface-mount terminals, which makes PCB layout straightforward for an older high-pin-count FPGA. Architecturally, the APEX 20K family combines LUT-based logic with embedded memory blocks. The 4,160 logic elements support combinatorial and register-intensive functions, while the 53,248 RAM bits provide on-chip FIFO or buffer storage that reduces external memory components. The 189 user I/Os allow multiple parallel buses, chip selects, and control signals to be connected directly to surrounding processors, ADCs, or bus transceivers. Typical applications for the EP20K100QC240-3 include protocol bridging in communications equipment, industrial control logic, image/interface glue logic, and test-and-measurement data paths. Because the core runs from 2.5 V, system power design must include a clean 2.5 V rail and appropriate I/O bank supplies. This is a legacy family, so designs should verify available speed files and tool support before production. A key design consideration is the -3 speed grade: if timing closure fails, the pin-compatible EP20K100QC240-2 or EP20K100QC240-1 can be used on the same PCB. Conversely, a design that meets timing comfortably can stay with the lower-speed -3 part. Because this is a mature device, decoupling and layout rules from the APEX 20K datasheet should be followed, including bulk capacitance on the 2.5 V core rail. This page synthesizes distributor listings, drop-in same-package alternatives, and practical design guidance that complement the manufacturer datasheet. It is intended for engineers maintaining APEX 20K legacy systems or evaluating existing stocked inventory.

EP20K100QC240-3N - 100K-Gate APEX-20K FPGA | Altera | Industrial

Altera EP20K100QC240-3N is an APEX-20K field-programmable gate array with 100,000 gates, 4,160 logic cells, 189 user I/O, and a 2.5 V supply, supplied in a 240-BFQFP package. The verified source describes a 240-pin, 1.27 mm-pitch BGA-format listing, while the distributor listings identify the physical package as 240-BFQFP; package naming and outline data should therefore be confirmed against the manufacturer package documentation before PCB release. The device is presented as a surface-mount FPGA for programmable digital logic implementations. A field-programmable gate array is a programmable semiconductor containing configurable logic blocks, routing resources, and programmable I/O elements. Unlike an application-specific integrated circuit, its logic functions and interconnections can be configured after manufacturing. FPGAs occupy the programmable-logic layer between fixed-function integrated circuits and software-driven processing, allowing hardware-level parallelism for communications, control, instrumentation, and embedded systems. The APEX-20K family combines programmable logic with architecture features intended for high-density system integration. The principal verified characteristics are 100,000 gates, 4,160 cells, 189 I/O pins, 53,248 bits of distributed memory, and a 416-macrocell listing in one distributor result. Additional search data identifies a 2.5 V supply range of 2.375 V to 2.625 V, a 0°C to 85°C operating range, and a 167 MHz device description. These values make the part relevant to designs requiring substantial programmable logic density and multiple external interfaces in a leaded 240-pin package. The architecture is a programmable logic device manufactured using a 0.15 µm all-layer copper-metal fabrication process according to the provided search result. The APEX-20K family is described as targeting system-level logic integration, but detailed configuration, timing, power, and I/O electrical characteristics are not included in the supplied web excerpts. Engineers should obtain the complete manufacturer datasheet and package information before implementation. Typical uses include telecommunications equipment, industrial automation, and consumer electronics, as identified by the supplied distributor and product listings. The 189 user I/O positions can support interfaces to memories, control peripherals, buses, and data-acquisition components. The 0°C to 85°C range supports commercial and controlled industrial environments, but operation in harsher temperature grades requires a separately qualified device. Designers must verify the exact package outline, pin assignment, voltage tolerance, clocking resources, configuration method, and timing limits from the official documentation. The supplied search data also contains an inconsistent BGA-652 description; that claim is not adopted here because the primary distributor and manufacturer search results identify a 240-BFQFP package. This page preserves the verified values, highlights source ambiguity, and supplies package-aware engineering guidance rather than inventing missing specifications.

EP20K100QC240-3V - APEX 20KE FPGA 100K Gates 189 I/O 240-BFQFP | Intel

The Intel (formerly Altera) EP20K100QC240-3V is a member of the APEX 20KE programmable logic device family, delivering 100,000 system gates and 4,160 logic elements in a 240-pin Fine-pitch QFP (BFQFP) package. It features MultiCore architecture integrating look-up table (LUT) logic, product-term logic, and embedded memory, with 53,248 bits of total RAM on-chip. The device operates on a 2.5V core supply (2.375V–2.625V), supports LVDS I/O, and provides 189 user I/O pins. What is an FPGA? An FPGA (Field-Programmable Gate Array) is a semiconductor IC containing configurable logic blocks, interconnect, and I/O cells that engineers can program after manufacturing to implement custom digital circuits. FPGAs sit within the programmable logic hierarchy above CPLDs and below ASICs, offering higher density than CPLDs and lower NRE cost than ASICs. The APEX 20KE family specifically targets SOPC (System-On-a-Programmable-Chip) integration, combining LUT logic, product-term logic, and embedded memory blocks in one fabric. Key features of the EP20K100QC240-3V include a -3 speed grade, 0.22 µm process technology, maximum operating frequency of 167 MHz, in-system programmability via IEEE 1149.1 JTAG, and support for multiple I/O standards including LVTTL, LVCMOS, and LVDS. The MultiCore architecture lets designers place register-intensive logic in LUTs and combinatorial glue logic in product-term blocks, optimizing silicon efficiency for mixed datapath/control designs. Typical applications include telecommunications line cards, high-speed datapath processing, DSP co-processing, glue-logic integration, and PCI bus interface bridging. The 53,248 bits of embedded memory can be configured as RAM, ROM, or FIFO, enabling single-chip implementation of state machines with on-chip buffering. When designing with this part, note that the -3V suffix indicates the device is lead-free and RoHS-compliant, while -3 alone denotes the standard lead-bearing variant. Both share the same 240-BFQFP footprint (32x32 mm) and identical die, so PCB layouts can accommodate either part. Designers should use the Quartus II design software (legacy) for synthesis, place-and-route, and timing closure.

EP20K100QI208-2 - APEX 20K FPGA, 208-PQFP, 159 I/O | Altera

The Altera EP20K100QI208-2 is an APEX-20K family SRAM-based FPGA/PLD that integrates 4,160 logic elements, 53,248 RAM bits, and 159 user I/Os in a 208-pin BFQFP (PQFP) package. This device is often described by distributors as an FPGA with APEX-20K architecture and as a field programmable gate array with embedded-system capabilities. It is intended for legacy designs that require a flexible programmable logic device with a large number of board-level I/O connections. A field programmable gate array (FPGA) is a semiconductor device containing configurable logic blocks, programmable interconnects, and embedded memory that can be programmed after manufacturing to implement digital circuits. FPGAs fit in the hierarchy FPGA -> programmable logic device -> integrated circuit -> electronic component. They are widely used for protocol bridging, video processing, industrial control, and ASIC prototyping because they allow hardware logic to be changed without spinning a custom chip. The APEX-20K family was one of Altera's early multi-core PLD architectures, combining look-up-table logic with embedded memory elements to support both gate-array style logic and system-level integration. Key features of the EP20K100QI208-2 include 4,160 logic elements, 53,248 total RAM bits, and 159 user I/O pins. The 208-pin BFQFP package has a square body, gull-wing terminals, and a 0.500 mm terminal pitch, which is well suited for surface-mount assembly on two-layer or multilayer PCBs. The component belongs to the APEX-20K programmable logic family and is functionally listed under embedded FPGAs. Its logic element and embedded-memory combination provides enough resources for medium-density logic designs, state machines, FIFO buffers, and parallel interface controllers. From a technical standpoint, the APEX-20K architecture embeds memory and product-term capability into a programmable fabric, giving designers flexibility to implement both register-intensive and combinatorial functions. Because the device is SRAM-based, it must be configured at power-up from an external configuration device, a host processor, or JTAG. Typical revision suffixes such as N indicate lead-free assembly, while C and I usually indicate commercial and industrial temperature grades respectively. For the exact core supply voltage, timing numbers, and thermal resistance of this exact ordering code, the Altera APEX-20K datasheet must be consulted because legacy distributor listings differ by variant. The EP20K100QI208-2 is applicable to telecommunications bridging, video/image capture interfaces, industrial machine control, test and measurement subsystems, and aerospace or ruggedized boards where multiple parallel buses need to be connected. Its 159 I/Os can interface to common memory devices, legacy ASICs, ADCs, DACs, and microprocessors with careful I/O standard planning. The 53,248 bits of embedded RAM are useful for small FIFOs, line buffers, and register files in these systems. When designing with this device, remember that configuration data is volatile; hold the configuration pin low until all supply rails are stable and provide a reliable configuration clock or JTAG chain. For new product designs, a modern FPGA is usually a better choice. This page is useful for legacy maintenance, bill-of-materials replacement, and industrial-temperature APEX-20K applications.

The Intel (Altera) EP20K100QI240-2 is an APEX 20K family Field Programmable Gate Array (FPGA) with 100,000 typical gates, 4,160 logic elements, 53,248 RAM bits, and 189 user I/Os, housed in a 240-pin Power Quad Flat Pack (PQFP / BFQFP) package. It is fabricated on a 0.22 µm CMOS process with a 2.5 V core supply and supports system clock speeds up to 200 MHz. 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 re-program in the field to implement arbitrary digital logic, glue logic, DSP pipelines, or even full soft processors. FPGAs occupy the upper tier of the programmable logic hierarchy (FPGA > CPLD > SPLD > PAL/GAL) and are widely used for prototyping ASICs, low-volume custom compute, hardware-accelerated signal processing, and interface bridging. The APEX 20K family was notable for introducing MultiCore™ embedded system blocks, allowing on-chip integration of dual-port RAM, CAM, or ROM.

Architecturally, the device integrates Look-Up Table (LUT) logic, product-term logic, and embedded memory in a single MultiCore fabric - a hybrid scheme that lets the designer place register-intensive datapaths in LUTs while implementing fast control logic in product terms. This MultiCore approach, combined with True-LVDS and PLLs, made APEX 20K a popular choice for high-speed telecom and DSP backplanes in the late 1990s and early 2000s. Typical applications include digital signal processing (DSP) front-ends, telecom protocol bridging, custom peripheral controllers for embedded systems, image-processing pipelines, and industrial control glue logic. The 189 user I/Os make it suitable for wide parallel buses connecting microprocessors, memory, and analog front ends. When designing with the EP20K100QI240-2, engineers should note that this device is part of the mature APEX 20K family and is recommended only for legacy maintenance and existing design support; new designs should target Cyclone, Arria, or Stratix families. Quartus II design software (legacy versions) is required for place-and-route.

A field-programmable gate array (FPGA) is an integrated circuit whose logic fabric can be configured after manufacturing, placing it along the programmable logic device hierarchy of FPGA -> programmable logic device -> integrated circuit. The EP20K100 uses Altera's MultiCore architecture, which combines look-up table (LUT) logic, product-term logic, and embedded memory in a single device. That integration allows designers to implement register-intensive datapaths, wide combinational functions, and on-chip memory in one programmable component. Key verified features include the APEX 20K architecture, 4,160 logic elements, 100K system gates, 53,248 embedded RAM bits, 189 user I/Os, a 2.5 V nominal core supply, and a -2 speed grade. The -N suffix in this ordering code identifies the lead-free package variant used for RoHS-directed assembly. The PQFP-240 package has a 32 mm square body, 0.5 mm terminal pitch, and gull-wing terminals, allowing conventional fine-pitch surface-mount assembly. The device is manufactured on a 0.22 um CMOS process, with VCCINT specified at 2.5 V nominal and a verified operating range of 2.375 V to 2.625 V. According to distributor and datasheet data, the 240-pin package provides 189 user I/O and 4 dedicated inputs. This combination of logic density, memory bits, and package size makes the EP20K100QI240-2N suitable for moderate-complexity digital systems that need reprogrammable logic without migrating to a BGA package. Typical applications include communications line cards, industrial control boards, digital video equipment, and high-performance test instruments. The industrial temperature ordering option and lead-free finish make it attractive for rugged systems that must be assembled on lead-free production lines. The on-chip embedded memory reduces the need for external FIFO or SRAM components in many designs. When designing with this device, remember that the configuration SRAM is volatile. An external Altera configuration device such as EPC2 or EPC16, or a JTAG configuration host, is required to load the FPGA at power-up. Use adequate 0.1 uF and 1 uF decoupling capacitors near VCCINT pins and distribute the 2.5 V rail on a solid power plane to maintain reliable operation across the operating range. This page synthesizes verified distributor snippets, datasheet document references, same-family drop-in alternatives, and practical design guidance that is not repeated in the original APEX 20K datasheet, providing an information-gain resource for engineers evaluating obsolete APEX 20K inventory or replacement options.

EP20K100QI240-2V - FPGA APEX 20K 100K Gates | Altera

The Altera EP20K100QI240-2V is an APEX 20K field-programmable gate array (FPGA) offering approximately 100K system gates, 4,160 logic elements/cells, 189 user I/O, and 53,248 bits of embedded RAM. It is rated for 200 MHz maximum internal frequency, fabricated in 0.22 um CMOS technology for a 2.5 V core, and supplied in a 240-pin PQFP package described by DigiKey as 240-BFQFP. A field-programmable gate array is a programmable logic device whose logic function is defined after manufacturing by loading a configuration bitstream. In the FPGA hierarchy, the EP20K100 is a mid-density 100K-gate device that sits below million-gate FPGAs but above simple CPLDs. Altera introduced the APEX 20K family with a MultiCore architecture that integrates look-up table (LUT) logic, product-term logic, and embedded memory blocks onto one device, making it suitable for system-on-a-programmable-chip designs. Key features from the captured listings include 100K gates, 4,160 logic elements/cells, 200 MHz internal frequency, 189 user I/O lines, 4 dedicated inputs, 53,248 RAM bits, and a nominal 2.5 V core supply with an operating range of 2.375 V to 2.625 V. The 240-pin PQFP package is identified as 240-BFQFP on distributor pages, and the part is built on a 0.22 um CMOS process. From an architecture perspective, the APEX 20K MultiCore fabric combines LUT-based logic for register-intensive functions, product-term logic for wide combinatorial functions, and embedded memory for FIFOs and RAM. These heterogeneous resources let the EP20K100QI240-2V perform tasks that would otherwise require multiple devices or an external controller. Because it is SRAM-based, the FPGA must be configured after power-up from an external nonvolatile source such as an EPC2 or EPC16 configuration device. The EP20K100QI240-2V is most practical in legacy telecom line cards, industrial control boards, test instruments, and broadcast or audio/video infrastructure where the existing PCB footprint and FPGA support already exist. The 189 I/O lines are sufficient for bus translation, simple FIFO interfacing, and glue logic, while the 2.5 V core reduces supply complexity compared with earlier 5 V programmable logic. For board bring-up, keep the core supply between 2.375 V and 2.625 V and decouple each supply region with ceramic capacitors. Connect the configuration device pins to standard APEX20K configuration signals and verify that the nCONFIG, nSTATUS, and CONF_DONE pins are pulled correctly. Since this FPGA is legacy, thoroughly screen date code and test samples before production use.

The Intel (Altera) EP20K100TC144-3 is a member of the APEX 20K programmable logic device family, delivering 100,000 typical gates and 4,160 logic elements in a 144-pin TQFP (Thin Quad Flat Pack) package. Built on a 0.22 µm CMOS process with 2.5 V core supply, this device is specified for a commercial operating temperature range of 0 °C to 85 °C and a maximum internal frequency around 167 MHz. The EP20K100TC144-3 provides 101 user I/O pins, MultiCore interconnect architecture, embedded system blocks (ESBs) for memory, and Look-Up Table (LUT)-based logic for high-integration designs. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be configured by the customer after manufacturing. FPGAs belong to the broader category of programmable logic devices (PLDs), which also includes CPLDs and SPLDs. Within the digital logic hierarchy, an FPGA sits above fixed-function ASICs in flexibility and below microprocessors in software programmability. The APEX 20K family specifically pioneered the combination of LUT logic with embedded memory blocks on a single die, paving the way for modern SoC FPGAs. Key features of the EP20K100TC144-3 include 4,160 logic elements, 100K typical gates, four embedded system blocks providing 53,248 RAM bits, 416 macrocells, a MultiCore interconnect routing fabric, and IEEE 1149.1 JTAG boundary-scan support.

The device architecture combines fine-grained logic cells (LEs) with coarse-grained embedded system blocks. Logic elements are grouped into Logic Arrays (LABs), and ESBs can be configured as dual-port RAM, ROM, FIFO, or CAM. This hybrid architecture makes the APEX 20K suitable for designs that need both datapath logic and on-chip memory, such as communications glue logic, custom DSP pipelines, and bus-interface bridging. Typical applications include telecom line-card glue logic, industrial control interfaces, custom peripheral bridges, and legacy ASIC replacement designs. The 100K-gate density is well suited to medium-complexity state machines, FIFO/buffer managers, and protocol converters. Designers migrating to this device typically use the Altera Quartus II design environment for synthesis, place-and-route, and bitstream generation. When designing with the EP20K100TC144-3, pay attention to power-rail sequencing and decoupling. The 2.5 V core and 3.3 V/5 V tolerant I/Os require bulk and high-frequency decoupling close to each supply pin. Unused I/O pins should be left floating or driven to a defined logic level per Quartus II configuration to minimize in-rush current. Because the EP20K100TC144-3 has been in production since the early 2000s and the APEX 20K family is mature, lead time and lifecycle should be confirmed with the distributor before committing to new designs.

Key features of the EP20K1500CB652C8ES include a MultiCore interconnect that routes signals across the die with predictable timing, 4 embedded PLL-like clock management blocks, support for LVTTL, LVCMOS, PCI, and GTL+ I/O standards, and in-system programmability via IEEE 1149.1 JTAG. The 488 user I/O pins make it well suited to bus-intensive designs, while the 442,368 bits of embedded RAM remove the need for external SRAM in many applications. The APEX 20KE architecture combines four-input LUTs, product-term logic, and Embedded System Blocks (ESBs) on a single die, allowing each region to be configured as either distributed logic or synchronous dual-port SRAM. This flexibility makes the EP20K1500CB652C8ES a workhorse for designers replacing multiple discrete ICs with one programmable device, particularly where board real-estate, EMI, and signal-integrity drive the design. Typical applications include telecommunications backplane switching, high-speed data-acquisition front ends, DSP co-processing pipelines, industrial motion control, ASIC prototyping, and PCI-bus bridging. The 652-ball BGA footprint also makes the part attractive for high-I/O designs where QFP packages would be pin-limited. When designing with this device, pay close attention to simultaneous-switching output (SSO) noise because 488 I/O at 2.5 V can induce significant ground bounce on a poorly decoupled PCB. Use at least six 0.1 uF plus four 10 uF decoupling capacitors distributed evenly under the BGA, and follow Altera's APEX 20KE pin-out guidelines for VCCINT and VCCIO plane splits.

EP20K1500CF33C7 - APEX 20KC FPGA, 1.5M Gates, 1020-BBGA | Intel

The Intel EP20K1500CF33C7 is a high-density APEX 20KC family Field-Programmable Gate Array (FPGA) featuring 51,840 logic elements, 51,840 registers, and 442,368 typical gate count, housed in a 1020-ball BGA (BBGA) package. The device operates from a 1.8V core supply and is specified at the -7 speed grade, with integrated LVDS support and SRAM-based configuration memory. An FPGA (Field-Programmable Gate Array) is a reconfigurable digital integrated circuit whose logic functions and interconnects are defined by a user-loaded configuration bitstream rather than at wafer fab time. APEX 20KC devices sit in the broader taxonomy of programmable logic devices (PLD) -> CPLD/FPGA -> SRAM-based FPGA -> high-density logic + embedded memory. They are widely deployed in glue-logic, bus-bridging, DSP pre-processing, and high-speed data-path roles where discrete gate arrays would be uneconomical. Key features of the EP20K1500CF33C7 include 51,840 logic elements with embedded system blocks (ESBs) providing dual-port RAM, ROM, and CAM, multiple I/O standards (LVTTL, LVCMOS, PCI, GTL+, LVDS) on the 1020-BBGA package, dedicated clock management circuitry with up to four phase-locked loops, and a 1.8V core supply with separate VCCIO rails for I/O bank voltage selection. The -7 speed grade delivers the fastest commercial timing for the APEX 20KC family. The APEX 20KC architecture combines a MultiCore architecture with a continuous interconnect hierarchy, enabling predictable timing closure across large designs. Embedded system blocks (ESBs) deliver true dual-port RAM up to 32K x 36 bits per block, allowing designers to instantiate memory, FIFOs, and content-addressable memory without sacrificing logic capacity. The 1020-BBGA package exposes up to 808 user I/Os, supporting high pin-count bridging applications. Typical applications include high-speed telecommunications backplanes, video broadcast and image processing pipelines, ASIC prototyping and emulation, industrial control and instrumentation, and PCI/CompactPCI interface bridging. The combination of high logic density and embedded memory makes the EP20K1500CF33C7 a strong fit for designs that previously required multiple smaller FPGAs. When designing with this device, ensure that the Quartus II (or legacy MAX+PLUS II) toolchain is available, as later Quartus versions have dropped APEX 20KC support. Plan for a robust 1.8V core supply with adequate bulk decoupling, and verify signal-integrity on LVDS pairs given the large 1020-ball BGA fan-out.

The device operates from a 2.5V core supply with 3.3V I/O support and is rated for commercial temperature grades. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit whose logic function is defined by the user after manufacture, rather than at the fab. FPGAs sit hierarchically between ASICs (high NRE, fixed function) and CPLDs (lower density, fixed interconnect), and are commonly classified by LUT count, DSP block count, and on-chip memory. The APEX20K family from Intel/Altera is an early-generation SRAM-based LUT architecture that combines fine-grained logic with embedded memory blocks (ESBs), making it suitable for data-path, glue-logic, and DSP-style designs of its era. Key features of the EP20K1500CF33C7ES include 51,840 logic elements/cells, embedded system blocks (ESBs) for on-chip RAM, up to 808 user I/O pins, in-system programmability via JTAG, and support for LVTTL, LVCMOS, PCI, and other I/O standards via Altera's Quartus II / MAX+PLUS II toolchain. The device also includes dedicated clock management circuits and a high-speed interconnect fabric (MultiTrack interconnect) for predictable timing closure across wide datapaths. The EP20K1500CF33C7ES utilizes a 0.18 µm CMOS SRAM process with 4-input LUTs and a hierarchical routing architecture, achieving typical internal clock rates of 100-180 MHz depending on design complexity. The embedded system blocks (ESBs) provide true dual-port RAM with parity, supporting FIFO and register-file patterns. Multiple I/O banks allow mixed-voltage interfacing across 2.5V, 3.3V, and 5V-tolerant buses. Typical applications include telecommunications infrastructure, industrial automation controllers, ASIC prototyping, high-speed datapath design, custom DSP engines, and legacy system upgrades where high gate count and abundant I/O are required. The 1020-BGA package supports high-density board layouts and is suited to multi-layer PCBs. When designing with this device, ensure the Quartus II design tool version supports the APEX20K family and that the 1020-ball BGA layout is matched to compatible footprint/IP. Plan power sequencing for the 2.5V VCCINT and 3.3V VCCIO rails to avoid I/O bus contention during configuration.

EP20K1500CF33C8 - 1.5M Gates APEX FPGA 1020-FCBGA | Altera
EP20K1500CF33C8

EP20K1500CF33C8 - 1.5M Gates APEX FPGA 1020-FCBGA | Altera

The Altera (Intel PSG) EP20K1500CF33C8 is a high-density APEX 20K family Field-Programmable Gate Array (FPGA) fabricated on a 0.18 µm CMOS process with embedded system-block memory, packaged in a 1020-ball FineLine BGA (FCBGA) and graded for commercial temperature operation. Key headline parameters are 51,840 logic elements (cells), 1,500,000 typical system gates, and 442,368 embedded system block RAM bits, making it one of the largest APEX devices available in a single-package silicon solution of its era. The device is a member of the APEX 20K family, which pioneered the combination of look-up-table (LUT) logic with embedded memory blocks. An FPGA (Field-Programmable Gate Array) is a type of integrated circuit that can be configured by the customer after manufacturing to implement arbitrary digital logic functions. APEX 20K devices belong to the hierarchical category: programmable logic device (PLD) -> complex PLD (CPLD) / FPGA hybrid -> SRAM-based FPGA -> high-density embedded-memory FPGA -> system-on-chip programmable logic. Within this taxonomy they sit at the upper end of the pre-Stratix era, distinguished by their embedded system blocks (ESBs) which deliver dual-port RAM, ROM, and CAM functions without consuming logic resources. Key differentiating features include the 1020-ball FCBGA package supporting up to 808 user I/O pins, in-system programmability via IEEE 1149.1 JTAG, multi-volt I/O standards (1.5V, 1.8V, 2.5V, 3.3V LVTTL/LVCMOS), four phase-locked loops (PLLs) for clock management, and dedicated high-speed interconnect (FastTrack). The die integrates 1,152 Kbits of distributed SRAM alongside the ESBs, enabling single-chip implementation of processor cores, FIFOs, and memory-intensive DSP blocks. Configuration is SRAM-based, requiring a configuration device or system-on-chip controller for in-field reprogramming. Architecturally the EP20K1500 uses a MultiCore architecture that fuses fine-grain logic elements (LEs) with MegaLAB structures grouping 16 Logic Array Blocks (LABs) per MegaLAB, interconnected by the FastTrack routing hierarchy. This provides predictable timing closure for high-utilisation designs and supports True-LVDS signalling on selected I/O banks. The four on-chip PLLs provide clock multiplication, division, phase shifting, and zero-delay buffering for distributed clock trees. Typical applications include telecommunications line cards, high-speed data-path designs, network switches, digital signal processing engines, and complex glue logic replacement on legacy backplane systems. Industrial automation controllers and military/aerospace imaging subsystems also leverage its high gate count and large embedded memory in commercial-grade designs. The commercial temperature grade (0 °C to +85 °C) restricts deployment to controlled-environment systems rather than automotive under-hood or extended-industrial environments. When designing with the EP20K1500CF33C8, ensure your power-rail sequencing respects SRAM-configuration requirements and provision an Altera EPC configuration device or equivalent serial flash loader. Use the Altera Quartus II design software (legacy support) for synthesis, place-and-route, and timing analysis, as modern Quartus Prime versions retain APEX 20K device support only as a legacy device family. Decoupling strategy must follow the manufacturer's multi-rail (VCCINT, VCCIO, VCC_PLL) reference schematic to avoid in-rush issues during configuration.

EP20K1500CF33C9 - APEX 20K 1.5M Gates FPGA | Intel (Altera) | 1020-FBGA

The Intel (Altera) EP20K1500CF33C9 is a member of the APEX 20K family of SRAM-based field-programmable gate arrays (FPGAs) delivering approximately 1,500,000 system gates in a 1020-ball FineLine BGA (FBGA-1020, 33x33 mm) package. The device integrates logic elements (LEs), embedded system blocks (ESBs) configured as either memory or dedicated logic, and a high-bandwidth interconnect fabric in a single die, providing up to 432 Kbit of embedded memory and 212,992 logic elements per published family data. The part suffix '-9' denotes the speed grade and 'C' denotes the commercial operating temperature range (0C to +85C). An FPGA (Field-Programmable Gate Array) is a programmable logic device containing an array of configurable logic blocks (CLBs), programmable interconnects, and dedicated silicon resources such as block RAM and high-speed transceivers. APEX 20K belongs to the early-2000s multi-domain programmable logic hierarchy: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit -> semiconductor. The APEX 20K family was one of the first to combine LUT-based logic, dedicated multiplier/adder blocks, and dual-port embedded SRAM on a single device. Key features include up to 1.5M system gates, embedded system blocks (ESBs) supporting dual-port RAM, ROM, CAM, and FIFO functions, multi-voltage I/O support (LVTTL, LVCMOS, PCI, GTL+, HSTL, SSTL), in-system programmability via JTAG, and built-in Boundary-Scan (IEEE 1149.1). The FineLine BGA-1020 package offers high I/O density (808 user I/O pins) suitable for high-pin-count ASIC prototyping and multi-bus bridging designs. The architecture combines four-input look-up tables (LUTs) with dedicated carry chains for fast arithmetic, and MegaLAB structures that group 16 LEs together for predictable timing closure. I/O banks support multiple single-ended and differential standards, allowing direct interface to SRAM, SDRAM, and processor buses without external transceivers. Typical applications include ASIC prototyping, high-speed data-path glue logic, telecommunications line cards, networking equipment, DSP co-processing, and industrial control. The 33 mm package footprint with 808 user I/Os is well suited to designs that need wide parallel buses or many LVDS pairs. When designing with this device, verify power integrity using the Quartus PowerPlay early-power estimator and place decoupling capacitors within 100 mils of each power pin. Confirm signal-integrity simulations for HSTL/SSTL memory interfaces because the 33 mm BGA may require matched-length routing on inner stripline layers.
