EP20K60EQC208-1 - APEX 20KE FPGA 60K Gates | Altera
The Altera EP20K60EQC208-1 is an APEX 20KE field-programmable gate array (FPGA) with 60,000 system gates, 2,560 logic elements, 32,768 bits of embedded RAM, and 148 user I/O pins, supplied in a 208-pin BQFP/PQFP package that operates from a 1.8 V core supply. An FPGA is a semiconductor device that contains thousands or millions of programmable logic cells and programmable interconnect. Unlike a fixed-function ASIC, an FPGA can be configured after manufacturing using a bitstream that defines logic functions, memory maps, and I/O behavior. In the power electronics and embedded systems hierarchy, an FPGA sits between simple CPLDs and high-end ASSP/SoC devices; it provides design flexibility by allowing engineers to implement custom digital logic, protocol bridges, and DSP pipelines without committing to a custom mask. The EP20K60EQC208-1 belongs to Altera's APEX 20K family, which combined look-up-table logic blocks with embedded memory and high-speed interconnect. Key features that differentiate this device include 60K usable system gates, 2,560 logic elements, 32,768 RAM bits, and 148 user I/O pins in a 208-lead BQFP package. The device is CMOS-based and operates with a 1.8 V core supply, making it suitable for low-voltage, mid-density board designs. According to available distributor listings, the speed grade supports internal operation up to 250 MHz, and the C temperature grade is specified for 0°C to 85°C operation. The package uses gull-wing square quad flat-pack construction for surface-mount assembly. Architecturally, the EP20K60EQC208-1 uses the APEX 20K MultiCore architecture, which integrates LUT-based logic cells, embedded system blocks, and high-speed routing resources. This lets a single FPGA implement state machines, memory functions, and data-path operations on one chip, reducing board area compared with multiple smaller programmable logic devices. The device also supports system-on-a-programmable-chip (SOPC) design flows, enabling soft processor and peripheral integration on older 1.8 V designs. Its 148 user I/O pins can connect to a wide range of board-level buses, but exact I/O standard support and drive capability must be checked in the official APEX 20K datasheet. Typical applications include legacy telecom line-card bridging, industrial control I/O expansion, video interface conversion, digital signal pre-processing, and prototype/education boards where 1.8 V FPGA logic is acceptable. The combination of embedded RAM and 60K gates makes it particularly useful where a design needs moderate FPGA resources but cannot migrate to a newer 1.2 V or 0.9 V fabric. A practical design consideration is that the core is 1.8 V, so the board must allocate a stable 1.8 V rail separate from any higher-voltage I/O plane. The device is a legacy APEX 20K part; for new production designs, a current Intel programmable device is usually preferred, but for repairing or maintaining existing APEX 20K systems, the EP20K60EQC208-1 remains a relevant pin-compatible target. This page adds distributor-verified availability clues, drop-in APEX 20K alternatives, and design guidance for legacy FPGA maintenance that are not printed on a distributor cart page.
EP20K60EQC208-1X FPGA - 60K Gate 250MHz, 1.8V | Intel
The Intel (formerly Altera) EP20K60EQC208-1X is an APEX 20KE field-programmable gate array (FPGA) with 60K typical gates, 2,560 logic elements/cells, 148 user I/Os, and 32,768 RAM bits. Fabricated in 0.22um CMOS and operating from a 1.8V core supply, it supports a listed internal frequency of 250MHz and comes in a 208-pin PQFP (BFQFP) surface-mount package. A field-programmable gate array (FPGA) is a semiconductor device containing configurable logic blocks, programmable interconnects, and embedded memory that the designer configures after manufacturing. FPGAs sit above complex programmable logic devices (CPLDs) in capacity and are used to implement parallel logic, protocol bridging, DSP pipelines, and system-on-a-chip solutions. The EP20K60EQC208-1X belongs to the APEX 20K family, which Altera positioned as a system-on-a-programmable-chip (SOPC) platform combining look-up-table logic, product-term structures, and memory resources on a single 1.8V device. Understanding this hypernym is important because FPGA selection is driven by gates, logic elements, RAM bits, I/O count, package, speed grade, and configuration options rather than a single datasheet parameter. Key features of the EP20K60EQC208-1X include its 60K-gate capacity, 2,560 logic elements, 148 user I/O pins, and 32,768 RAM bits. The listed 250MHz internal frequency and 0.22um CMOS process allow it to handle moderately fast parallel data paths in legacy industrial and communication boards. Its 208-pin PQFP package provides a practical pin count for board routing, and the commercial 0C to 85C temperature range covers indoor and telecom equipment environments. The -1X speed designation represents the fastest ordering-code class visible in the fetched listings, making it preferable where timing closure is tight. Architecturally, the APEX 20KE family was one of Altera's first MultiCore-based FPGA families, integrating look-up-table logic, product-term logic, and embedded memory resources. The 1.8V core voltage reduces power compared with earlier 2.5V and 3.3V FPGAs while retaining I/O flexibility for legacy 3.3V and 2.5V interfaces when VCCIO is correctly configured. The 2,560 logic elements can be used as synchronous counters, state machines, datapath FIFO controllers, or small parallel multipliers, while the RAM bits support FIFO buffers and register files without consuming external SRAM. Because the device is not in active production today, exact timing models should be taken from the archived APEX 20K device handbook and validated in the Altera/Intel Quartus version that supports this device family. Typical applications for the EP20K60EQC208-1X include communications line-card bridging, industrial control logic, legacy test and measurement pattern generation, high-speed data buffering, video scan conversion, and medical front-end interfacing. Its 148 user I/Os make it useful for connecting parallel buses, memories, and peripheral controllers on legacy 1.8V/2.5V/3.3V boards. For new designs, the device is usually selected only when form-fit-function replacement or supply continuity is required; otherwise a modern FPGA offers greater density and lower power. A key design consideration is that EP20K60EQC208-1X must be configured after power-up from an external EPC2 or EPC16 configuration device, or through JTAG, since SRAM-based FPGAs lose their configuration on power loss. The 1.8V core voltage must be supplied separately from the I/O voltage, and all VCC/GND pins require correct decoupling. If a board already uses an APEX 20K 208-pin PQFP footprint, the -1 and -2 speed variants listed on this page can serve as drop-in supply-chain alternatives after timing verification. This page synthesizes distributor inventory, same-family drop-in alternatives, practical design guidance, and cross-reference information that is not consolidated in the manufacturer datasheet. It is intended to help engineers identify replacements, avoid obsolete-part pitfalls, and understand where the EP20K60EQC208-1X still fits in legacy system maintenance and repair.
EP20K60EQC208-2 - APEX-20KE FPGA 60K Gates 200MHz | Intel
The Intel (formerly Altera) EP20K60EQC208-2 is a member of the APEX-20KE® programmable logic device family, integrating 60,000 gates and 2,560 logic elements into a single CMOS FPGA die. Housed in a 208-pin Power Quad Flat Pack (PQFP / BFQFP) package measuring 28 mm × 28 mm, the device is built on a 0.22 µm process and operates from a 1.71 V to 1.89 V core supply with internal performance up to 200 MHz. The part exposes 148 user I/Os and supports both LVTTL and LVCMOS I/O standards, making it a flexible glue-logic and bus-interface solution for mid-1990s-to-early-2000s designs. An FPGA (Field Programmable Gate Array) is a reprogrammable semiconductor device whose logic function is defined by a user-loaded configuration bitstream rather than by hard-wired mask layers. Within the broader taxonomy, an FPGA belongs to the class of programmable logic devices (PLDs), alongside CPLDs (Complex Programmable Logic Devices) and SPLDs (Simple Programmable Logic Devices). FPGAs occupy the high-density, high-performance end of that hierarchy, enabling integration of processor cores, memory controllers, and custom datapaths on a single chip, and serve as a foundational technology in modern digital design. Key features of the EP20K60EQC208-2 include its MultiCore™ architecture, which combines a Look-Up Table (LUT) based logic fabric with embedded array blocks (EABs) suitable for implementing RAM, ROM, and FIFO memories. The device includes four phase-locked loops (PLUs) for clock synthesis and skew management, supports in-system programmability (ISP) via the IEEE 1532 boundary-scan interface, and offers built-in JTAG support for board-level testability. Typical applications for this device include telecom line-card glue logic, industrial control bus bridges, PCI bus interface controllers, and legacy peripheral aggregation. The wide I/O count allows direct connection to address and data buses without external transceivers, simplifying board layout in cost-sensitive embedded systems. When designing with this part, ensure that your configuration memory is supplied with a stable 1.8 V rail and that the JTAG chain is properly terminated. Designers should consult the APEX 20KE device handbook for Quartus II programming flow and timing constraints. This page consolidates distributor pricing, drop-in alternatives, and design notes not readily available in the manufacturer datasheet.
EP20K60EQC208-2N - 60K Gate APEX 20KE FPGA | Intel
The Intel EP20K60EQC208-2N is an APEX 20KE field-programmable gate array (FPGA) with 60,000 typical gates, 2,560 logic elements, 148 user I/O pins, and a 200 MHz maximum internal frequency rating, supplied in a 208-pin BFQFP/PQFP package. It is the lead-free N-suffix variant of the -2 speed-grade EP20K60E device and operates from a nominal 1.8 V core supply. A field-programmable gate array is an integrated circuit that can be reconfigured after manufacturing to implement arbitrary digital logic. FPGAs sit above simple programmable logic devices in the digital logic hierarchy, offering gate counts in the tens of thousands or more, embedded memory, and flexible I/O. The APEX 20KE family combines FPGA lookup-table logic with product-term support, creating a system-on-a-programmable-chip architecture that designers can use for protocol bridging, DSP front ends, and custom interface logic. Key features of the EP20K60EQC208-2N include 60,000 typical gates, 2,560 logic elements, 148 user I/O pins, and a 1.72 ns propagation delay reported by DigChip. The family is fabricated in 0.22 um CMOS and is specified for operation from 0 to 85 °C. The 208-pin square PQFP package measures 28 mm by 28 mm and uses gull-wing terminals, making it suitable for conventional surface-mount assembly. Architecturally, APEX 20KE devices integrate look-up-table logic, product-term macrocells, and embedded memory blocks, allowing the same device to handle register-intensive state machines and data-path functions. The -2 speed grade is a mainstream performance option between the slower -3 grade and the faster -1 or -1X grades. The N suffix indicates lead-free finish, which is important for RoHS-oriented production lines. Typical applications include telecom and line-card bridging, industrial control logic, display and video interface controllers, and high-speed ADC/DAC front-end aggregation. The 148 user I/Os are sufficient for 16-bit or 32-bit parallel buses plus control signals. The 200 MHz internal clock capability also supports moderate-rate packet processing and custom coprocessing tasks. When designing with the EP20K60EQC208-2N, confirm the FPGA configuration method during schematic design and provide adequate decoupling on the 1.8 V core rail. Because this is an older APEX 20KE part, avoid assuming indefinite factory availability for high-volume new designs unless the supply chain has been explicitly validated. This page synthesizes distributor availability, package-specific guidance, speed-grade comparisons, and practical design notes that are not always visible on a manufacturer datasheet. The data is maintained as of 2026-09-08 and reflects current web sources.
EP20K60EQC208-2X - APEX-20KE FPGA, 60K Gates, 208-PQFP | Intel
The Intel (formerly Altera) EP20K60EQC208-2X is a member of the APEX-20KE family of field-programmable gate arrays (FPGAs) delivering 60,000 typical ASIC gates and 32,768 bits of embedded memory in a 208-pin Power Quad Flat Pack (PQFP / BFQFP) package. The device integrates 2560 logic elements, 148 user I/O pins, and 4 embedded PLLs (LVDS-capable), fabricated on a 0.22 µm CMOS process with MultiCore architecture combining look-up table (LUT) and product-term (EAB) logic in a single fabric. An FPGA (Field-Programmable Gate Array) is a programmable logic device that allows hardware designers to configure arbitrary digital circuits using a matrix of configurable logic blocks (CLBs), embedded memory blocks, and routing interconnects. The APEX-20KE belongs to the broader taxonomy: FPGA -> programmable logic -> configurable logic IC -> semiconductor. It is particularly suited to SOPC (System-On-a-Programmable-Chip) integration, where processor cores, memory, and custom peripherals coexist on a single reprogrammable device, replacing what would otherwise require multiple ASICs or a microcontroller plus external glue logic. Key specifications of the EP20K60EQC208-2X include 32,768 system gates per the APEX-20KE datasheet, 32,768 RAM bits across embedded array blocks (EABs), 4 phase-locked loops, and a maximum internal frequency of 200 MHz with propagation delays as low as 1.72 ns. The device operates from a 1.8 V core supply (1.71 V – 1.89 V) and supports multi-voltage I/O standards (LVTTL, LVCMOS, PCI, SSTL, LVDS) on its 148 user I/O pins, all routed through 8 I/O banks. Architecturally, the APEX-20KE family introduced MultiCore logic, embedding MegaLAB structures that group 16 logic elements (LEs) plus a single EAB into a building block that can be configured as either wide fan-in product-term logic or as LUT-based fine-grained logic. This dual-mode fabric targets both datapath-style register-intensive designs and PAL/PLA-style state-machine code. The 'X' speed grade places this part in the -2X performance bin, while the industrial 0 °C to 85 °C operating temperature range fits commercial and industrial embedded designs. Typical applications include telecommunications line cards, industrial control glue logic, PCI interface bridging, digital signal processing pre-processing, and legacy ASIC prototyping. The wide-gate-count headroom (60K gates) makes it suitable for glue-logic consolidation where a discrete CPLD-plus-microcontroller pair would otherwise be required. A practical design tip when using this part: configure the four PLLs early in the Quartus design flow because LVDS I/O and clock-domain skew are easier to close when PLL block placement is locked before fitter routing. This page synthesizes pricing, drop-in alternatives, design notes, and parameter comparisons not found in the manufacturer datasheet alone, supporting engineers evaluating the EP20K60EQC208-2X for legacy or long-lifecycle designs.
EP20K60EQC208-2XN - 60K-Gate APEX-20KE FPGA, 208-PQFP | Intel
The Intel EP20K60EQC208-2XN is a high-density APEX-20KE series Field Programmable Gate Array (FPGA) featuring 60,000 typical gates, 2,560 logic elements, and 32,768 bits of embedded RAM, housed in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) surface-mount package. The device is fabricated on a 0.22 µm CMOS process and operates from a 1.8 V core supply (1.71 V to 1.89 V). According to the manufacturer datasheet, the part provides 148 user I/Os and supports internal clock frequencies up to 200 MHz (with a propagation delay of approximately 1.72 ns per logic element). A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines thousands of configurable logic blocks, programmable interconnect, and on-chip memory into a single semiconductor. Within the broader taxonomy, an FPGA sits above simple CPLDs in density and below ASICs in non-recurring engineering cost. The APEX-20KE family introduced MultiCore architecture, merging LUT-based logic (efficient for data-paths, register-intensive math, and DSP) with product-term logic (efficient for control/state machines) on the same die, plus dedicated embedded system blocks (ESBs) for memory. This makes the APEX-20KE a hybrid logic-and-memory platform rather than a pure LUT device. Key differentiating features include 2560 logic elements, 32 Kbits of distributed RAM, in-system programmability via JTAG, MultiVolt I/O support for interfacing to 1.8 V, 2.5 V, 3.3 V and 5 V buses, and a built-in PLL for clock management. The '-2' speed grade and 'N' suffix denote the commercial temperature range (0 °C to 85 °C) and lead-free, RoHS-compliant packaging per the FindIC summary. The EP20K60EQC208-2XN is typically used in telecommunications line cards, industrial control backplanes, and legacy PCI bridge designs where high logic density and large embedded RAM are required. Designers migrating to newer Cyclone or MAX families should treat this part as a long-term-support / last-time-buy candidate rather than a greenfield choice. When designing with this device, provide at least four 0.1 µF decoupling capacitors around the package perimeter, keep the PLL power island isolated, and program the configuration bitstream via the ByteBlaster or Master/Slave serial modes documented in the APEX-20KE datasheet. The 208-PQFP is a perimeter-lead package, so PCB escape routing is straightforward but limits pin density versus a BGA. This page synthesizes distributor stock data, parametric cross-references, and practical design considerations that are not collected in any single manufacturer document.
EP20K60EQC208-3 - APEX 20KE FPGA 60K Gates 208-PQFP | Intel / Altera
The Intel / Altera EP20K60EQC208-3 is a member of the APEX-20KE family of Field Programmable Gate Arrays (FPGAs), delivering 60,000 typical gates, 2,560 logic elements, and 32,768 bits of embedded SRAM in a 208-pin Plastic Quad Flat Pack (PQFP / BFQFP) package. Built on a 0.22 µm CMOS process with a 1.8 V core supply, the device integrates up to 148 user I/Os and provides MultiCore™ system-on-a-programmable-chip (SOPC) integration including look-up tables (LUTs), product-term logic, and embedded memory blocks on a single die. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit whose logic fabric, interconnect, and I/O behavior are defined by user-programmed configuration data rather than fixed mask geometry. Within the broader taxonomy of programmable logic devices (PLDs), FPGAs sit above simple CPLDs in density and complexity, supporting full system-on-chip (SoC) integration, high-speed parallel processing, and large embedded memory. The APEX 20KE family introduced MultiCore™ architecture to merge LUT-based and product-term-based logic elements on one fabric, enabling designers to choose the optimal logic primitive for each block of a design. The EP20K60EQC208-3 supports a maximum internal frequency of 160 MHz, with propagation delays around 1.72 ns and a speed grade of -3, making it suitable for high-performance glue logic, bus interfaces, and datapath acceleration in telecom, industrial, and military-aerospace systems. The device offers 32768 bits of embedded SRAM, dedicated high-speed I/O banks, and supports LVTTL, LVCMOS, PCI, and other common interface standards through programmable I/O standards. Typical applications for the EP20K60EQC208-3 include telecommunications line cards, ASIC prototyping, DSP front-end co-processing, high-speed bridge and protocol conversion, and industrial control. Designers also use this part for legacy system upgrades where 5V-tolerant or 3.3V PCI I/O is required, and where the 208-pin PQFP footprint allows through-hole-friendly PCB assembly for rugged environments. When designing with the EP20K60EQC208-3, ensure proper decoupling with 0.1 µF and 10 µF capacitors placed close to each supply pin, and follow Altera's Quartus / MAX+PLUS II configuration guidelines for JTAG or passive serial configuration modes. Note that the part is mature and may be subject to last-time-buy notices; verify current lifecycle status with authorized distributors before committing to new designs. This page consolidates distributor pricing, verified cross-references to APEX 20KE speed-grade variants, and practical design notes not found in a single source — saving hours of manual datasheet cross-checking for engineers maintaining legacy Altera designs.
EP20K60EQC208-3N - APEX 20KE FPGA 60K Gates 148 I/O | Intel
The Intel (Altera) EP20K60EQC208-3N is an APEX-20KE Field Programmable Gate Array (FPGA) with approximately 60,000 typical gates, 2,560 logic elements, 32,768 bits of embedded RAM, and 148 user I/Os, supplied in a 208-pin plastic quad flat pack package sometimes called BFQFP or PQFP-208. It is the commercial-temperature, lead-free (-N), speed-grade -3 variant of the EP20K60 family and operates from a 1.8 V core supply. An FPGA is a semiconductor device containing a fabric of programmable logic elements, embedded memory, and general-purpose I/O that can be configured after manufacturing to implement digital logic circuits. Unlike fixed-function ASICs or ASSPs, FPGAs allow engineers to change the hardware design through configuration files, enabling rapid prototyping and field-hardware revisions. FPGAs sit within the broader programmable-logic hierarchy: FPGA -> programmable logic device (PLD) -> integrated circuit -> semiconductor. APEX-20KE was Altera/Intel s MultiCore architecture family that integrated look-up-table logic, product-term macrocells, and embedded RAM on a single chip. The EP20K60EQC208-3N key features include 2,560 logic elements, 32,768 embedded RAM bits, and 148 user I/O pins in a compact 208-pin QFP. According to the search data, it has a maximum internal frequency of 182 MHz for the -3 speed grade, a 3.56 ns propagation-delay class, and commercial 0 C to +85 C operating temperature range. The pin-and-lead-free suffix N means this device uses lead-free solder finish. The 1.8 V core reduces dynamic power relative to older 2.5 V or 3.3 V programmable-logic families while retaining compatibility with intellectual-property cores from the APEX era. The APEX-20KE architecture combines a look-up-table-based FPGA granularity with embedded system-level blocks, allowing designs such as protocol bridges, DSP front ends, and memory controllers to be implemented in one component. The 148 user I/Os provide considerable parallel connectivity for glue logic replacement in legacy systems. Because this is an SRAM-based FPGA, it must be configured at power-up from an external configuration device or host processor. The -3 speed grade is a moderate-speed bin intended for cost-sensitive applications that do not require the fastest -1X performance. Typical applications include telecom line-card interface logic, industrial machine control, video timing/format conversion, medical imaging signal conditioning, and data-acquisition front ends where a reprogrammable Altera-compatible footprint is needed. Designers should respect the 1.8 V core-power pin count and place decoupling capacitors close to every VCC and VCCIO pin. The enable/configuration pins must be pulled according to the APEX 20K configuration guidance. For new designs, this part is a legacy device and may not be recommended; check current Intel/Altera lifecycle or choose modern equivalents when feasible. This page synthesizes distributor pricing, drop-in Altera/Intel APEX-family alternatives, and practical design notes not found in the manufacturer datasheet.
EP20K60EQC240-1X - APEX-20KE FPGA, 60K Gates, 240-PQFP | Intel / Altera
The Intel / Altera EP20K60EQC240-1X is a member of the APEX-20KE Field Programmable Gate Array family, delivering 60K gates with 2560 logic elements in a 240-pin PQFP (Plastic Quad Flat Pack) package. It operates on a 1.8V core supply (1.71V to 1.89V), supports up to 151 user I/Os, and is manufactured on a 0.22-micron CMOS process. The device is part of Altera's MultiCore architecture combining look-up table (LUT) logic with embedded memory blocks for system-on-a-programmable-chip (SOPC) integration. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be reconfigured by the designer after manufacturing. FPGAs sit in the programmable logic hierarchy between simple PLDs/CPLDs and fixed-function ASICs. The APEX-20KE family specifically targets high-density, high-performance designs where on-chip memory and DSP-style arithmetic matter, bridging the gap between traditional glue logic and full custom silicon. Key features of the EP20K60EQC240-1X include up to 250 MHz internal operation, MultiCore architecture integrating embedded memory with LUT logic, in-system programmability via SRAM configuration, and 196 maximum user I/Os in the BGA variant. The '1X' speed grade places the part in Altera's commercial performance tier with 1.72 ns propagation delay. The 'E' suffix denotes the enhanced APEX-20KE revision with improved memory and I/O features over the original APEX-20K family. The architecture combines four-input LUTs with embedded array blocks (EABs) for memory and DSP functions. Each EAB can be configured as RAM, ROM, or multiplier blocks, allowing the device to absorb soft-core processors, FIFOs, and signal-processing datapaths directly into the fabric. The 1.8V core and MultiVolt I/O support interface to 1.8V, 2.5V, 3.3V, and 5V systems without external level translation. Typical applications include telecommunications line cards, networking equipment, industrial control and automation, ASIC prototyping, and DSP front-end preprocessing. The combination of dense logic and embedded memory is well suited for protocol conversion, packet processing, and custom glue logic in mid-volume designs. When designing with this part, verify that your Quartus version still targets the legacy APEX-20KE device family, as newer Quartus releases have dropped legacy device support. Also confirm package availability - this device is in EOL/Obsolete status per industry sources, so design-in for new products is discouraged unless a long-life agreement exists.
EP20K60EQC240-2 - APEX-20KE FPGA, 151 I/O | Altera
The Altera EP20K60EQC240-2 is an APEX-20KE field-programmable gate array (FPGA) delivered in a 240-pin BQFP/PQFP package with 151 user I/O pins, a core supply range of 1.71 V to 1.89 V, and a commercial operating temperature range of 0 °C to +85 °C. It is an established Altera programmable-logic device now listed through Rochester Electronics and distributor channels as an obsolete/end-of-life component. An FPGA is a semiconductor device containing programmable logic blocks and interconnect that can be configured to implement arbitrary digital circuits after manufacturing. In Altera’s product hierarchy, the EP20K60EQC240-2 is specifically an APEX-20KE FPGA, which falls under the broader categories of field-programmable gate array, programmable logic device, integrated circuit, and semiconductor. Understanding this hierarchy helps engineers evaluate replacement options, legacy system risks, and configuration-memory requirements when reusing this 2000s-era device in existing boards. Key features visible in distributor listings include 151 user I/Os in a 240-BQFP/PQFP shape, 1.71 V to 1.89 V core operation, a 0 °C to +85 °C commercial temperature range, CMOS logic family, and an APEX-20KE family designation. Mouser additionally mentions 256 macrocells in the APEX 20K family listing. The package is a 32 mm x 32 mm PQFP with gull-wing leads, which is suitable for conventional surface-mount assembly but requires a dedicated 240-pin footprint. From an architecture standpoint, the APEX-20KE family was marketed as one of the industry’s first programmable-logic families to integrate system-on-a-programmable-chip capabilities, using a MultiCore architecture that combines LUT-based logic, product-term macrocells, and embedded system blocks. The -2 suffix indicates the speed-grade ordering option, while related -1X and -2X variants share the same 240-pin PQFP package in the same family. Because this is an older family, exact usable gate count, RAM bits, and timing values should be obtained from the complete Altera APEX 20K family datasheet rather than inferred from ordering-code fragments. Typical applications for this part include telecom line cards, industrial control I/O boards, medical imaging preprocessing systems, video acquisition interfaces, and automatic test equipment where moderate logic density and parallel I/O are needed. The 151 user I/Os allow designers to connect a CPU bus, external SRAM, status LEDs, and multiple serial interfaces without adding excessive CPLD glue. However, because the device is obsolete, all new designs should include a lifecycle risk assessment. A key design consideration is supply decoupling and configuration memory. The core 1.8 V rail must be within the listed 1.71 V–1.89 V window and decoupled according to the full APEX 20K datasheet recommendations. For board bring-up, remember that an FPGA requires a configuration bitstream from an EPC-series or JTAG source; do not assume the device is self-configuring at power-up. This page synthesizes distributor availability and pricing as of 2026-09-08, same-package drop-in variants, parametric comparison information, and practical legacy-system design notes that are not all present in a single datasheet snippet.
EP20K60ETC144-1X - 60K-Gate APEX-20KE FPGA, 144-LQFP | Intel/Altera
The Intel/Altera EP20K60ETC144-1X is a 60,000-gate APEX-20KE family Field-Programmable Gate Array (FPGA) IC integrating 2,560 logic elements, 32,768 bits of embedded RAM, and 92 user I/Os into a single MultiCore architecture die, housed in a 144-pin LQFP (Low-profile Quad Flat Pack) surface-mount package. What is an FPGA? An FPGA (Field-Programmable Gate Array) is a programmable logic device that engineers configure after manufacturing using a hardware-description language such as VHDL or Verilog. FPGAs occupy the hierarchical niche between fixed-function Application-Specific Integrated Circuits (ASICs) and software-driven microcontrollers; they deliver ASIC-class parallel processing performance while retaining full post-fabrication reprogrammability. The APEX-20KE family, introduced by Altera in the late 1990s, was one of the industry's first system-on-a-programmable-chip (SOPC) families combining Look-Up Table (LUT)-based logic with embedded memory blocks. Key features include a 1.8V core supply (operating range 1.71V to 1.89V), four dedicated inputs and 88 I/O pins (92 total user I/Os), 0.22-micron CMOS process technology, and 1.72 ns propagation delay with internal clock rates up to 160 MHz. The MultiCore architecture integrates logic elements, embedded system blocks (ESBs) for RAM and ROM, and FastTrack interconnect for predictable timing closure. The 144-LQFP (20x20 mm, 0.5 mm pitch) package offers gull-wing leads for reflow soldering on standard FR-4 PCBs. On the architectural side, the EP20K60E combines distributed LUT-based logic with 16 embedded system blocks of dual-port RAM, each block configurable as 2,048-bit memory. This is the engineering reason the family was marketed as an SOPC platform - the embedded RAM, combined with dedicated clock-management circuitry, allowed single-chip implementation of peripherals, FIFOs, and small microcontrollers. The 92 user I/Os are 5V-tolerant inputs with programmable drive strength and slew-rate control. Typical applications include industrial control logic, telecommunications glue logic, legacy PCI bridge implementations, network interface glue, and embedded control systems. The 0 to 85 degrees C commercial operating range suits factory-floor and office-equipment use. Hobbyist retro-computing projects also frequently adopt APEX-20KE devices due to their abundant documentation. When designing with the EP20K60ETC144-1X, observe the 1.8V core supply requirement and provide proper decoupling (100 nF plus 10 uF bulk) near the VCCINT pins. Note that the device is mature, EOL-classified by Intel, and now serviced by authorized distributors such as Rochester Electronics for long-term support. Quartus II is the supported design toolchain.

EP20K60ETC144-2N - APEX-20KE 60K FPGA, 92 I/O, 144-TQFP | Intel
The Intel (formerly Altera) EP20K60ETC144-2N is a member of the APEX-20KE family of Field Programmable Gate Arrays (FPGAs), delivering 60,000 typical gates and 2,560 logic elements in a 144-pin TQFP package. It integrates 32,768 bits of embedded system memory (ESB), supports up to 92 user I/O pins, and operates from a 1.71 V to 1.89 V core supply, manufactured on a 0.22 µm CMOS process. The -2 speed grade targets internal frequencies up to 160 MHz with a 1.72 ns propagation delay, and the industrial temperature range of 0 °C to 85 °C is suited for commercial and lab environments. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the integration density of an ASIC with the flexibility of in-system reprogrammability. FPGAs sit within the broader hierarchy of semiconductor devices as: programmable logic -> PLD -> FPGA -> high-density programmable logic. The APEX-20KE family specifically introduced MultiCore architecture combining Look-Up Table (LUT)-based logic, product-term blocks, and embedded memory in a single fabric, enabling System-on-a-Programmable-Chip (SOPC) integration. Key features of the EP20K60ETC144-2N include 2,560 logic elements, 32 Kbits of distributed ESB memory, 92 usable I/O pins compliant with LVTTL/LVCMOS/LVDS/PCI interfaces, and JTAG-based IEEE 1149.1 boundary-scan support. The 144-TQFP package (20 × 20 mm body, 0.5 mm pitch) is surface-mountable with standard JEDEC MSL handling. The -2 speed grade is mid-tier within the APEX-20KE family, balancing timing margin against cost. The APEX-20KE architecture combines four-input LUTs, embedded memory blocks (ESBs), and product-term logic on a MultiCore fabric. Each ESB can be configured as ROM or RAM and supports dual-port operation. The 0.22 µm process and 1.8 V core VCC deliver low static power relative to 5 V legacy PLDs, while still preserving the high-drive 3.3 V PCI compatibility at the I/O banks via dedicated PCI-compliant buffers. Typical applications include telecommunications line-card glue logic, PCI bus interface bridges, industrial control front-end preprocessing, DSP co-processing front-ends, and high-speed custom state machines. With 60 K gates and 92 I/Os, the device targets mid-complexity designs that exceed CPLD capacity but do not justify larger Cyclone or Stratix devices. When designing with this part, verify that the Quartus design tool supports the EP20K60ETC144-2N device code (older Altera legacy support), and note that the -2 speed grade must be back-annotated into the project's fitter settings. Confirm power budgeting for the 1.8 V rail, since high-utilization designs may exceed 1 A. This page synthesizes distributor stock, same-family Altera/Intel drop-in alternatives, and design considerations not found in the legacy datasheet alone, providing a single reference for engineers evaluating the EP20K60ETC144-2N for new designs or legacy maintenance.
EP20K60ETC144-2X - APEX 20KE FPGA 60K Gates 92 I/O 144-TQFP | Intel
The Intel (Altera) EP20K60ETC144-2X is a member of the APEX 20KE programmable logic device family, integrating 60,000 typical gates (25,600 logic elements, 2,560 macrocells per the DigiKey product listing) in a 144-pin TQFP (20x20 mm) surface-mount package with 92 user I/Os. It is built on a 0.22 µm CMOS process, operates from a 1.71 V to 1.89 V core supply, and is specified for commercial 0 °C to 85 °C operation with internal frequency up to 160 MHz and pin-to-pin propagation delay of 1.72 ns. What is an APEX 20KE FPGA? The APEX 20KE is the second-generation Advanced Programmable eXtended (APEX) architecture from Altera (now Intel PSG), which pioneered System-on-a-Programmable-Chip (SOPC) integration by embedding high-density logic, embedded array blocks (EABs), and LVDS-capable I/O into a single die. APEX devices sit at the top of the SRAM-based PLD hierarchy - PLD > CPLD > FPGA > APEX 20KE - and were Altera's flagship high-density logic family before being superseded by Stratix and Cyclone. Key features include MultiCore architecture combining Logic Array Blocks (LABs) for fine-grained logic and Embedded System Blocks (ESBs) for memory and specialty functions, 4 dedicated inputs plus 92 bidirectional I/Os totaling 96 user terminals, support for LVTTL/LVCMOS/PCI I/O standards, and in-system programmability via IEEE 1149.1 JTAG plus passive serial and Altera EPC configuration devices. The 1.8 V core with 1.72 ns propagation delay enables 160 MHz internal operation in combinatorial paths. Typical applications include telecommunications line cards, industrial control and motor-drive glue logic, PCI interface bridging, high-end consumer audio/video processing, and prototype ASIC emulation. The combination of 60 K usable gates and 92 I/Os in a low-cost plastic TQFP makes it well suited to volume production where BGA rework would be uneconomical. Design consideration: the TQFP-144 footprint is the key reason this variant remains in long-life-cycle programs - migrating to a BGA-356 variant of the same die (e.g., EP20K60EBC356-2X) requires PCB rework and is not pin-compatible. When designing, derate the 160 MHz internal frequency to ≤ 120 MHz for cascaded carry chains and ≤ 80 MHz for ESB block-RAM access to meet timing closure with margin.
EP20K60ETC144-3 - APEX 20KE FPGA, 92 I/O, 144-LQFP | Intel
The Intel (formerly Altera) EP20K60ETC144-3 is a member of the APEX 20KE programmable logic family, delivering 2,560 logic elements in a 144-pin LQFP package with 92 user I/O pins. It is fabricated on a 0.22 µm CMOS process, operates from a 1.71 V to 1.89 V core supply, and supports user I/O voltages referenced through separate VCCIO rails typical of the APEX 20KE family. The '-3' speed grade corresponds to the slowest of the three available grades in this family, trading off timing margin for cost savings in non-critical-path designs. An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) that lets engineers implement arbitrary digital logic via a configurable array of logic elements (LEs), embedded memory blocks (ESBs), and routing resources. The APEX 20KE series specifically pioneered MultiCore integration of look-up table logic, embedded system blocks (ESBs for memory), and product-term blocks on a single die, fitting between pure CPLDs and modern high-density FPGAs. EP20K60ETC144-3 parts are well-known for low-power 1.8 V core operation, in-system programmability via JTAG, and broad Quartus II / MAX+PLUS II toolchain support. Key features of EP20K60ETC144-3 include 2,560 logic elements, 32,768 bits of embedded SRAM, 196 maximum user I/Os (package-limited to 92 in the 144-LQFP), and a maximum internal frequency of 160 MHz to 182 MHz depending on measurement method. The device supports multi-voltage I/O standards including LVTTL, LVCMOS, PCI, SSTL-2/3, and LVDS via dedicated I/O banks. It also includes built-in clock lock loops (analog PLLs) for clock conditioning. The APEX 20KE architecture combines four types of resources - LABs (Logic Array Blocks), ESBs (Embedded System Blocks for memory), MegaLAB structures, and FastTrack interconnect - to deliver a balance of register-rich logic, distributed SRAM, and predictable timing. The '-3' speed grade makes this part the lowest-cost option, ideal for telecom line cards, industrial controllers, and legacy networking equipment where 100 MHz+ operation is not required. Typical applications include telecommunications line interface cards, industrial automation controllers, legacy networking routers and switches, low-density DSP front-ends, and PCI bus interface glue logic. The 144-LQFP package supports hand-soldering and rework, making it attractive for prototype and low-volume production. When designing with this device, ensure 1.8 V core decoupling uses at least four 0.1 µF ceramic capacitors placed near the VCC pins. All unused I/O pins should be configured as tri-stated inputs with weak pull-ups in software to minimize power consumption. Note: this device is in the Intel/Altera legacy product portfolio; verify lifecycle status before committing to new designs.

EP20K60ETC144-3N - APEX-20KE FPGA 60K Gates 2560 Logic Elements 144-LQFP | Intel
The Intel EP20K60ETC144-3N is a member of the APEX-20KE family of FPGAs, integrating 60,000 gates, 2,560 logic elements and 32,768 bits of embedded memory in a 144-pin LQFP package (TQFP form factor with gull-wing leads). It operates from a 1.8V core supply, supports up to 92 user I/O pins, and is fabricated on a 0.22 µm CMOS process that delivers an internal frequency of 160–182 MHz with a 1.72 ns propagation delay, making it suitable for mid-density glue-logic, bus-interface, and DSP-front-end designs. A field-programmable gate array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the designer programs after manufacture to implement arbitrary digital functions. APEX-20KE specifically introduced MultiCore™ architecture integrating look-up tables, product-term logic, and embedded system-on-a-programmable-chip (SOPC) blocks, which placed it within the broader taxonomy of programmable logic devices: PLD → CPLD/FPGA → SRAM-based FPGA → APEX-20KE. This hierarchy matters when designers compare it against later Cyclone, Stratix or competing Xilinx Spartan families. Key features include 32,768 bits of embedded SRAM (ESB), 92 maximum user I/O, in-system programmability via IEEE 1149.1 JTAG, dedicated PLL-style clock networks (LVDSL/LVDS-style high-speed inputs available on selected banks), and a low-power 1.8V core. The device is offered in the commercial 0 °C to +85 °C temperature grade and uses a gull-wing surface-mount 144-LQFP (LFQFP code) with square body for standard SMT reflow. Architecturally, the APEX-20KE family combines fast on-chip SRAM and product-term logic with high-speed interconnect, enabling designers to consolidate multiple CPLDs and discrete glue logic into a single device. The 2560 logic cells and 60K typical gate count put this part in the lower-mid-density tier of legacy Intel/Altera programmable logic, often used for bus bridges, custom peripherals, and pre-processing pipelines feeding a host processor. Typical applications include telecom line-card interface logic, industrial control and instrumentation front ends, video pixel processing, military/aerospace retrofit boards where long-term Altera tooling is preserved, and legacy ASIC-replacement designs. The 144-LQFP footprint allows hand-rework and prototyping that smaller BGA packages cannot. When designing with this FPGA, ensure the Quartus II (or MAX+PLUS II) toolchain version supports the APEX-20KE device family - newer Quartus releases have removed legacy device support. Plan power-rail decoupling for the 1.8V VCCINT and any 2.5V/3.3V VCCIO bank supplies per the APEX-20KE handbook.

This high-density FPGA integrates multi-core architecture (MultiCore) hot-socketing support, embedded system blocks (ESBs) for memory and logic, and FastTrack interconnect routing to deliver high-speed data paths for telecommunications, networking, and DSP applications. The device is supplied in a 652-ball BGA with a -7 speed grade and commercial (0C to 85C) operating temperature, configured for full BGA pin mapping per the APEX II device family standard. An FPGA (Field Programmable Gate Array) is a type of integrated circuit whose logic function is defined after manufacturing by a configuration bitstream loaded into on-chip SRAM cells. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs), which also include CPLDs and PALs. APEX II FPGAs specifically target high-density system-on-chip integration, embedding RAM, ROM, and arithmetic logic into the same fabric so that designers can implement entire subsystems - PCI bridges, DSP datapaths, protocol controllers - on a single device. Key features include 1.5M typical gates (approximately 30K logic elements), dedicated LVDS-capable I/O, MultiCore hot-socketing allowing live insertion into a backplane without disturbing system operation, and embedded array blocks (EABs) for efficient RAM/ROM and product-term logic implementation. The FastTrack continuous routing fabric provides predictable timing across the die. The -7 speed grade corresponds to roughly 200 MHz internal performance, suitable for protocol processing, PCI bus interfaces, and high-throughput DMA controllers. Architecturally, the APEX II family combines a lookup-table (LUT) based logic array with embedded system blocks. Each ESB can be configured as a 4096-bit memory block or as a logic expansion region, and the LUT-based MegaLAB structure aggregates logic into rows and columns linked by the FastTrack routing. Configuration is volatile SRAM, requiring an external configuration memory (EPC or compatible) at power-up. The device supports multi-voltage I/O standards via dedicated bank supply pins (VCCINT for core, VCCIO for I/O banks). Typical applications include high-speed telecommunications backplanes, PCI/PCI-X bridge implementations, SDR/DSP baseband processors, networking routers, and high-performance custom computing accelerators. The 652-ball BGA package suits designs that need maximum I/O count for parallel buses or multiple high-speed serial channels. The commercial temperature grade (suffix "C7") targets lab, test, and indoor industrial environments rather than automotive or military ranges. When designing with EP2A15B652C7, engineers should use the Quartus II design suite (legacy Altera toolchain), which provides synthesis, place-and-route, timing analysis, and bitstream generation. Because APEX II is a mature/legacy family, designers should confirm long-term availability and lifecycle status before committing to new production runs.

FPGAs occupy a unique tier between fixed-function ASICs and software-driven microcontrollers: they offer hardware-level parallelism and deterministic timing while remaining fully reprogrammable. Within the broader taxonomy, the APEX II sits as a high-density programmable logic device under the umbrella of PLDs (programmable logic devices) -> programmable logic -> semiconductor ICs. The APEX II family was specifically engineered for data-path-intensive applications such as telecommunications bridging, video processing, and high-speed networking line cards. Key features include embedded dual-port RAM with True Dual-Port modes, support for up to 1.875 Mbits of internal memory, multi-level routing resources optimized for datapath routing, and 4-phase on-chip PLLs for clock management. The EP2A15B652C8 supports 16 hot-socketing-friendly I/O banks with MultiVolt I/O technology, allowing 1.5V, 1.8V, 2.5V, 3.3V, and 5V interfacing on a single device. Its high pin count makes it well-suited for bus-intensive designs requiring wide parallel datapaths. Typical applications include telecom line cards, SONET/SDH framers, ATM switches, high-speed video processing, and ASIC prototyping. The combination of high logic density, embedded memory, and MultiVolt I/O made APEX II a popular choice for bridging and routing applications in early-2000s telecommunications infrastructure. When designing with the EP2A15B652C8, plan thermal management around the BGA-652 substrate and follow Altera's recommended decoupling scheme (typically 0.1 µF and 10 µF capacitors near each VCCIO/VCCINT ball group). Configuration via JTAG or passive serial with a 1.5V PROM is the standard bring-up path for production hardware. This page consolidates distributor stock and pricing data, drop-in alternatives, and practical design notes not collected in any single datasheet, accelerating your sourcing and bring-up decisions for legacy APEX II designs.
EP2A15B652C9 - APEX II FPGA 15K LE 652-BGA | Altera (Intel PSG)
The Altera (Intel Programmable Solutions Group) EP2A15B652C9 is a member of the APEX II family of high-density SRAM-based FPGAs, offering approximately 15,600 logic elements and 425 Kbits of embedded system blocks in a 652-ball FineLine BGA package. It operates at a core voltage of 1.5 V with I/O banks supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V standards, and is rated for the commercial 0 C to +85 C temperature range with a -9 speed grade timing classification. An FPGA (Field Programmable Gate Array) is a programmable logic device that allows hardware designers to implement custom digital circuits after PCB fabrication. The APEX II architecture (Advanced Logic Element Matrix with Embedded Processor eXtensions, second generation) sits within the broader hierarchy: programmable logic device -> CPLD/FPGA -> SRAM-based FPGA -> APEX II family -> high-density ASIC-replacement class. APEX II parts combine Look-Up Table (LUT)-based logic, embedded system blocks (ESBs) for memory and arithmetic, and dedicated high-speed I/O structures, making them suitable for system-on-chip prototyping, custom datapaths, and glue logic consolidation. Key features include four phase-locked loops (PLUs) for clock synthesis, support for LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards, and embedded system blocks that can be configured as dual-port RAM, FIFO, ROM, or arithmetic functions. The -9 speed grade indicates the fastest available timing bin for this family, while the 652-ball BGA package supports high I/O density for memory-rich designs. Technically, the APEX II device uses a 1.5 V core supply with separate VCCIO pins per bank, allowing mixed-voltage interfacing without external level shifters. The four PLUs provide flexible clock management with multiply/divide and phase shifting, and the architecture supports the APEX II MultiVolt I/O feature so a single device can interface with 1.5 V, 1.8 V, 2.5 V, and 3.3 V peripherals simultaneously. Typical applications include telecommunications line cards, high-speed data acquisition front-ends, DSP co-processing blocks, ASIC prototyping platforms, and industrial control systems that require high logic density and high I/O count. The 652-ball BGA footprint also supports designs that demand significant external memory connectivity, including DDR-style interfaces on adjacent banks. Designers should note that APEX II devices require a configuration controller or external PROM, and JTAG-based in-system programmability is supported through the IEEE Std 1149.1 boundary-scan interface. Power sequencing must bring the core VCC up before VCCIO is applied to prevent excessive I/O drive current during startup.

An FPGA (Field Programmable Gate Array) is a type of programmable logic device that allows engineers to configure digital logic blocks and interconnect via a hardware-description language. FPGAs sit above ASICs and below microcontrollers in the design hierarchy: a microcontroller runs software sequentially, while an FPGA implements fully parallel custom hardware. The APEX II architecture specifically combines Look-Up Tables (LUTs), embedded system blocks (ESBs) for memory and arithmetic, and a high-bandwidth MultiTrack interconnect for predictable timing closure. Key features of the EP2A15B724C include 16,640 logic elements (LEs), 425,984 bits of embedded RAM, 492 maximum user I/O pins, and a 724-ball FCBGA package.

The APEX II architecture integrates embedded system blocks (ESBs) that can be configured as dual-port RAM, ROM, or first-in first-out (FIFO) buffers. Combined with the MultiTrack interconnect, this allows deterministic timing across deep pipelines and is why APEX II was widely adopted for high-speed protocol bridging and data-path designs before the Stratix generation replaced it. Typical applications for the EP2A15B724C include high-speed serial protocol bridging, telecom backplane switching, image-processing front-ends, ASIC prototyping, and military/aerospace signal processing. The high I/O count makes it suitable for designs that need to drive many parallel LVDS or TTL interfaces simultaneously. When designing with EP2A15B724C, engineers should use the Altera Quartus II design suite for synthesis, place-and-route, and timing analysis.

Architecturally, the EP2A15B724C7 uses Altera's MultiCore interconnect with embedded array blocks (EABs), logic array blocks (LABs), and FastTrack routing, achieving internal performance up to 500 MHz on critical paths. The 1.5 V core minimizes dynamic power relative to 2.5 V predecessors while maintaining signal integrity through dedicated LVDS I/O structures optimized for high-speed serial and parallel differential signaling in telecommunications and DSP backplanes. Typical applications include high-speed telecommunications backplanes, DSP processing cards, network switches and routers, ASIC prototyping, and parallel computing acceleration. The 1 Gbps True-LVDS support also makes it suitable for chip-to-chip interconnect between processors and memory subsystems on compact processor boards. When designing with this device, ensure 1.5 V core decoupling with low-ESR ceramic capacitors placed within 100 mils of each supply ball. The high pin count demands controlled-impedance PCB routing, and the BGA package requires X-ray inspection post-assembly. Configuration mode selection (PS, PPA, JTAG) must be set via MSEL pins before power-up.

EP2A15B724C8 - APEX II FPGA, 16K LE, 724-FCBGA | Intel
The Intel (formerly Altera) EP2A15B724C8 is a member of the APEX II family of programmable logic devices, integrating 16,640 logic elements and 425,984 RAM bits into a 724-pin flip-chip BGA (FCBGA) package. The device is fabricated on a 0.15 µm all-layer copper-metal process with up to eight metal layers, operates at a core voltage of 1.5 V, and supports internal clock frequencies up to 435 MHz. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that combines the density and performance of ASIC-class integration with the flexibility of in-system reprogrammability. APEX II sits within the broader hierarchy: FPGA -> programmable logic -> logic IC -> integrated circuit -> semiconductor. FPGAs like the APEX II family are typically deployed as glue logic, protocol bridges, custom datapath accelerators, and high-bandwidth parallel signal-processing engines in networking, telecom, and embedded compute platforms. Key differentiating features of the EP2A15B724C8 include 600K system gates, embedded True-LVDS differential signalling capable of 1 Gbps per channel, support for LVPECL, pseudo current mode logic (PCML), and HyperTransport interface signalling, and 492 user I/O pins for high-density parallel interconnect. The device integrates 4 PLLs for clock multiplication and deskew, and provides built-in LVDS termination and dynamic phase alignment, eliminating many external components. At the architectural level, the APEX II family uses a MultiCore architecture that combines look-up table (LUT) logic with embedded system blocks (ESBs) for on-chip RAM and content-addressable memory. The 16,640 logic elements can be configured for fine-grained combinational or registered logic, while 425,984 RAM bits can be partitioned into FIFOs, dual-port memories, or CAM blocks. Combined with 1.94 ns pin-to-pin logic delay, this gives the EP2A15B724C8 deterministic performance for latency-sensitive interfaces. Typical applications include high-speed serial backplanes, telecom line cards implementing ATM, SONET/SDH, or POS-PHY Layer 2/3 functions, multi-channel LVDS data acquisition front-ends, and embedded compute nodes that use HyperTransport for chip-to-chip interconnect. The 492 I/O pins and 1 Gbps LVDS capability make it well suited for high-bandwidth parallel-to-serial aggregation, while the embedded RAM supports deep packet buffers. When designing with the EP2A15B724C8, designers must observe the 1.5 V core supply requirement and provide proper decoupling across all VCC and VCCIO pins per the APEX II device family handbook. Signal integrity on 1 Gbps LVDS pairs requires controlled-impedance routing (typically 100 Ω differential) and matched pair lengths within the budget specified in the device datasheet. Designers should also confirm JTAG chain integrity and configuration mode (PS, AS, JTAG, or Fast Passive Parallel) prior to PCB fabrication. This page synthesizes distributor inventory, parameterized pricing tiers, drop-in alternatives, and design notes not aggregated in the original Altera/Intel datasheet, giving engineers a single reference for sourcing, comparing, and implementing the EP2A15B724C8.
EP2A15B724C9 - APEX II FPGA 16640 Cells 1.5V 724-BGA | Intel
The Intel (formerly Altera) EP2A15B724C9 is a high-density APEX II family Field Programmable Gate Array (FPGA) built on a 0.15 µm all-layer copper-metal process with up to eight metal layers, delivering 16640 logic elements, 425984 bits of embedded memory, and 492 user I/O pins in a 724-ball Fine-pitch Chip-Scale Ball Grid Array (FCBGA) package. It integrates up to 600,000 gates, operates from a 1.5 V core supply, and supports up to 500 MHz internal operation. The device family provides 1.5 V core operation with MultiVolt I/O supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V interface levels, allowing flexible bridging between modern low-voltage logic and legacy peripherals on the same board. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the designer can reconfigure after manufacturing. FPGAs sit in the digital logic hierarchy between simple PLDs/CPLDs and fixed-function ASICs: more capable than a CPLD for high logic density and DSP workloads, but lower NRE cost and faster time-to-market than a full ASIC. APEX II specifically targets high-density data-path and memory-rich designs such as telecommunications backplanes, video processing, and protocol bridging. Key features of the EP2A15B724C9 include 16640 logic elements, 425984 RAM bits distributed across embedded system blocks (ESBs) that can be configured as dual-port RAM, ROM, FIFO, or CAM, dedicated high-speed interconnect (FAST channel), and a clock network with PLL-based clock management. The 0.15 µm copper process and True-LVDS signaling deliver data rates up to 1 Gbps per LVDS pair, with additional support for LVPECL, PCML, and HyperTransport interface standards for chip-to-chip and backplane links. The APEX II architecture combines look-up-table (LUT) based logic elements with high-density embedded memory and a four-level hierarchical interconnect (LAB, MegaLAB, MegaLAB interconnects, FAST channel). MultiVolt I/O and on-chip termination simplify mixed-voltage board design, while the embedded PLLs provide precise clock synthesis, multiplication, division, and phase shifting across multiple clock domains. Typical applications include high-speed telecommunications backplanes using 1 Gbps LVDS links, video and image processing pipelines, network switches and routers, protocol bridging (e.g., SPI to LVDS, PCI to RapidIO), DSP co-processing cards, and ASIC prototyping. The 492 user I/O pins and 425984 bits of RAM make the EP2A15B724C9 well suited to designs that need many parallel interfaces plus substantial on-chip buffering. When designing with this device, place at least 8 to 12 low-impedance decoupling capacitors (0.1 µF and 0.01 µF) near each power pin to suppress switching noise on the 1.5 V core rail. Note that the APEX II family has been NRND for several years; for new designs, evaluate a Cyclone or Stratix equivalent from Intel's current portfolio unless the legacy footprint, I/O count, or qualification is mandatory.

EP2A15F672C7 - APEX II FPGA 16,640 LE 672-BGA | Intel | Altera
The Intel (formerly Altera) EP2A15F672C7 is a member of the APEX II family of Field Programmable Gate Arrays fabricated on a 0.15-µm all-layer copper-metal process with up to eight metal layers. The device integrates 16,640 logic elements (LEs), 425,984 bits of embedded system memory, and 492 user I/O pins in a 672-ball FineLine BGA package (27 mm × 27 mm body, 1.0 mm pitch). Operating from a 1.5 V core supply, the APEX II family supports True-LVDS signaling at 1 Gbps along with LVPECL, pseudo-current mode logic (PCML), and HyperTransport interface protocols for high-bandwidth interconnect. An FPGA (Field Programmable Gate Array) is a programmable logic device containing an array of configurable logic blocks (CLBs), embedded memory, DSP blocks, and programmable I/O elements interconnected by a routing fabric. FPGAs sit at the top of the programmable logic hierarchy (PLD > CPLD > FPGA) and are used for high-density parallel processing, glue logic, ASIC prototyping, and high-speed I/O bridging. The APEX II architecture combines look-up table (LUT) based logic with MultiCore interconnect, allowing designers to integrate entire system-on-chip functions on a single device. Key features of the EP2A15F672C7 include 16,640 logic elements, 425,984 system gates, a tPD of 1.69 ns, dedicated True-LVDS channels capable of 1 Gbps data rates, embedded RAM, and JTAG-based IEEE 1149.1 boundary-scan test support. The 672-ball FineLine BGA package provides robust signal integrity for high-speed designs and supports extensive user I/O for memory, bus, and backplane interfaces. Typical applications for the APEX II family include 1 Gbps backplane transceivers, high-performance ASIC prototyping, telecommunications line cards, parallel DSP processing, and high-speed serial I/O expansion. The True-LVDS support makes the device especially well suited for chip-to-chip and board-to-board links where multi-gigabit signaling is required. Designers working with this part should pay close attention to BGA fanout and the IBIS models for signal-integrity analysis. Power estimation should be performed using the Altera PowerPlay tool because the 1.5 V core current scales with toggle rate and routing density. This page combines distributor pricing, drop-in alternatives, and design considerations not found in the manufacturer datasheet alone, providing a consolidated reference for engineering and procurement teams.
EP2A15F672C7AA - APEX II FPGA 600K Gates 1.5V FC-FBGA672
The Intel (formerly Altera) EP2A15F672C7AA is a member of the APEX II family of programmable logic devices, manufactured on a 0.15-micrometer all-layer copper process and housed in a 672-ball flip-chip BGA package. The device integrates 600K typical gates (approximately 1.4M maximum system gates), 16,640 logic elements, and 492 user I/O pins, and operates from a 1.5V core supply. It is specified for commercial temperature grades and supports system speeds up to 500 MHz internally, with up to 1 Gbps True-LVDS, LVPECL, PCML, and HyperTransport I/O capability. An FPGA (Field-Programmable Gate Array) is a semiconductor IC containing an array of configurable logic blocks (CLBs/LEs), programmable interconnect, and I/O cells that the designer can wire up after manufacture using an HDL and a vendor toolchain (Quartus for Altera APEX II). FPGAs sit in the programmable-logic hierarchy above CPLDs and below fixed-function ASICs, and are typically chosen when time-to-market, design revision flexibility, or low-to-mid volume production outweigh the unit-cost advantage of an ASIC. APEX II parts in particular target high-speed communications and bus-interface applications that benefit from multi-gigabit transceivers. The EP2A15F672C7AA provides four enhanced PLLs for clock management, dedicated dual-port RAM blocks, and embedded content-addressable memory (CAM) blocks for look-up intensive functions. The MultiVolt I/O architecture allows each bank to be placed at 1.5V, 1.8V, 2.5V, or 3.3V, allowing direct interface to mixed-voltage peripherals without external level shifters. JTAG (IEEE 1149.1) boundary-scan and in-system programmability via the passive serial, fast passive parallel, or JTAG ports shorten board bring-up cycles. Typical applications for this part include high-speed serial interface bridging, telecom backplane aggregation, ASIC prototyping and emulation, bus-width conversion between PCI, PCI-X, and RapidIO links, and custom glue logic for storage and imaging subsystems. The 492 I/O count makes it suitable for designs that previously required a gate-array and benefit from being re-spinable in software. When designing with this device, attention must be paid to the FC-FBGA672 land pattern and PCB stack-up. The package requires a multi-layer board with controlled-impedance routing, microvia or via-in-pad technology, and matched-length traces on the LVDS pairs to maintain the 1 Gbps signaling budget. Decoupling must follow the reference design in the APEX II handbook (a minimum of 100 low-ESR capacitors distributed across the die area). The part has been flagged Last-Time-Buy / EOL by Altera (PDN dated Nov-Dec 2016), so new designs should consider the APEX II successor families or evaluate a Cyclone / Stratix equivalent.
