EP20K60EFC324-1 - 60K APEX-20KE FPGA, 196 I/O, 324-FBGA | Altera
The Altera (Intel) EP20K60EFC324-1 is a member of the APEX-20KE® family of Field Programmable Gate Arrays (FPGAs) housed in a 324-ball FineLine BGA (19x19 mm) package. The device integrates 60,000 typical gates and 2,560 logic elements with 32,768 bits of embedded memory, supporting up to 196 user I/O pins. According to distributor listings, the core is fabricated on a 0.22 µm process and operates from a 1.8 V supply (range 1.71 V to 1.89 V), with maximum core clock performance rated at 250 MHz. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and embedded memory blocks that can be rewired in the field to implement arbitrary digital logic. FPGAs sit within the broader hierarchy of programmable logic devices: FPGA -> programmable logic -> digital IC -> semiconductor. The APEX-20KE family is the enhanced (E-suffix) MultiCore™ architecture variant that combines look-up table (LUT)-based logic with embedded array blocks (EABs) for memory and arithmetic functions, allowing a single chip to host both glue logic and datapath/memory functions. Key features of the EP20K60EFC324-1 include 196 maximum user I/Os, 32,768 total RAM bits distributed across embedded array blocks, a 1.8 V core supply, and the compact 19x19 mm FBGA-324 package that is footprint-compatible across the APEX 20K E-series product family. The -1 speed grade offers the standard propagation delay tier for the family, suitable for general-purpose glue logic, datapath, and bus-interface applications operating up to 250 MHz. Technically, the APEX-20KE architecture combines fine-grained logic elements with MegaLAB™ structures that group multiple logic elements and EABs into a single high-speed interconnect domain, simplifying timing closure for wide datapath designs. The 1.8 V core supply reflects the migration to lower-voltage operation introduced in this enhanced family, reducing power consumption compared to the 2.5 V APEX-20K predecessors. Typical applications include telecommunications line cards, peripheral bus bridging (PCI to local bus), industrial control and factory automation, networking backplane glue logic, and legacy designs that were originally captured on the Quartus II 4.x/5.x toolchain. The 324-FBGA footprint also makes the part suitable for high-density adapter cards where 196 I/Os are needed without an excessively large board footprint. When designing with this part, note that the APEX 20KE family is supported by the legacy Quartus II design software and is no longer recommended for new designs - the family has been replaced by Cyclone and Stratix series FPGAs in current Intel FPGA roadmaps. Always verify long-term availability against your product lifecycle expectations before committing to new designs.

The Altera EP20K60EFC324-1X is a member of the APEX 20KE family of SRAM-based FPGAs delivering 60,000 typical gates with 2,560 logic elements (LEs) housed in a 324-ball FineLine BGA (19x19 mm) package. The device provides 196 user I/O pins, 32,768 bits of embedded RAM, and operates on a 1.8 V core supply (VCCINT 1.71 V to 1.89 V). The -1 speed grade targets internal frequencies up to 250 MHz in the APEX 20K architecture. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs / LEs) interconnected by a programmable routing fabric. APEX 20KE devices belong to the broader category of programmable logic devices (PLDs), which sit between standard microcontrollers (fixed-function, sequential execution) and ASICs (custom-mask, high-NRE). Within the system hierarchy, APEX 20KE FPGAs occupy the high-density, high-I/O niche used for bus interfacing, protocol bridging, and parallel DSP pre-processing. Key features include MultiCore architecture merging Look-Up Table (LUT) logic with embedded system blocks (ESBs) that double as RAM or product-term logic, four phase-locked loops (PLLs) for clock management, support for LVTTL, LVCMOS, PCI, SSTL-2/3, HSTL, and GTL+ I/O standards, and in-system programmability via IEEE 1532 / passive serial / passive parallel modes. The 19x19 mm 324-FBGA package offers a 1.0 mm ball pitch suitable for high-density multi-layer PCBs. Designed on a 0.22 µm CMOS process with five layers of metal interconnect, the APEX 20KE delivers high logic density and predictable timing closure via the Quartus II design environment. The LUT-based ESBs allow distributed dual-port RAM, FIFO buffers, and content-addressable memory blocks to be inferred directly from HDL. Typical applications include telecommunications backplane interfacing, ATM cell processing, high-speed data-path glue logic, and PCI bus bridging. The 60K-gate density makes it suitable for mid-range ASIC prototyping and DSP co-processing front-ends. The 1.8 V VCCINT and 1.5 V / 1.8 V / 2.5 V / 3.3 V VCCIO rails are typical for the generation. Design consideration: APEX 20KE devices require proper power-up sequencing (VCCINT before VCCIO, or simultaneous with monotonic ramp) and configuration-via-jtag or EPC configuration device; ensure decoupling with 0.1 µF and 10 µF capacitors within 100 mil of every supply pin. The 324-BGA footprint demands 4-layer or higher PCB stack-up for signal-integrity-preserving escape routing.

What is an FPGA? An FPGA (Field Programmable Gate Array) is a type of integrated circuit containing an array of programmable logic blocks, interconnect, and I/O cells that the designer configures after manufacturing. FPGAs sit in the broader hierarchy: programmable logic device (PLD) -> FPGA -> SOPC integration platform. The APEX-20KE family pioneered MultiCore architecture, integrating look-up tables (LUTs), embedded system blocks (ESBs) for memory, and product-term blocks into one fabric. Key features of the EP20K60EFC324-2N include 32,768 total RAM bits distributed across embedded system blocks, 196 maximum user I/Os supporting multiple I/O standards (LVTTL, LVCMOS, PCI, GTL+, HSTL, SSTL), and 32,768 system gates for high-density logic integration. The device supports in-system programmability via IEEE 1149.1 JTAG and Altera's passive serial configuration scheme, allowing rapid design iteration without removing the device from the board. The EP20K60EFC324-2N uses a fine-grain MultiCore architecture where each logic element (LE) combines a 4-input LUT, a programmable register, and carry/chain logic. The 32 Kbits of embedded memory can be configured as RAM, ROM, or FIFO, eliminating external memory in many glue-logic applications. The 1.8 V core reduces dynamic power compared with older 5 V and 3.3 V APEX predecessors, while 3.3 V tolerant I/O banks allow direct interface to legacy buses. Typical applications for this part include telecommunications line cards, industrial control and factory automation, military and aerospace prototyping, ASIC prototyping, glue-logic replacement, and high-speed parallel DSP pre/post-processing. The wide I/O count (196) and ample memory (32 Kbits) make it suitable for data-path bridging and protocol conversion designs. The 324-BGA package supports high-density board layouts with controlled-impedance signal routing. Designers should plan power sequencing for the 1.8 V core (use a low-dropout regulator with 3 A headroom), provide bulk decoupling on each VCCINT/VCCIO pin, and follow Altera's application note AN116 (configuration hardware) for JTAG chain and passive serial mode. The device operates commercially from 0 °C to 85 °C TJ, so thermal management is typically passive with copper pours.

The device architecture combines a fine-grained Look-Up Table (LUT)-based logic fabric with high-density memory blocks, enabling high-throughput datapath and DSP applications. The four PLLs provide flexible clock synthesis, frequency multiplication, and skew management, critical for synchronous designs operating across multiple clock domains. Typical applications include telecommunications infrastructure (SONET/SDH framer, ATM switching), high-speed serial protocol bridging, data acquisition systems with embedded FIFO buffering, and industrial control platforms with custom parallel interfaces. The 19×19 mm FBGA-324 footprint is suitable for moderate-density boards. When designing with this device, observe the 1.8 V (±5 %) core supply tolerance and place at least 8 decoupling capacitors (0.1 µF and 10 µF) around the periphery. JTAG pins should be pulled appropriately for reliable in-system programming.

Typical applications include telecommunications backplane interfacing, PCI bridge logic, high-speed data path conversion, and digital signal processing co-processors. The 60K-gate density is well-suited to multi-channel serial protocol bridging and image preprocessing pipelines. When designing with the EP20K60EFC324-3, plan power sequencing for the 1.8 V VCCINT rail and the 3.3 V VCCIO rails separately. Use the JTAG port for boundary-scan test and in-field firmware updates. Configure unused I/O pins as tri-stated inputs with weak pull-ups to reduce quiescent current and improve signal integrity. This page synthesizes distributor pricing, same-family drop-in alternatives, and practical design notes not found in a single manufacturer datasheet, giving engineers a faster path to part selection.

It operates from a 1.8 V core supply within a 1.71 V to 1.89 V range and supports a maximum internal clock frequency of 182 MHz in this -3 speed grade. The device is built on a 0.22 um CMOS process and is specified for commercial temperature environments from 0°C to 85°C. An FPGA is an integrated circuit whose logic fabric can be reprogrammed after manufacturing using hardware description languages such as VHDL or Verilog. Unlike fixed-function ASICs, an FPGA contains configurable logic blocks, embedded memory, and routing resources that allow a designer to create custom datapaths and state machines in firmware. The APEX 20KE family from Altera combines a programmable logic array with embedded system blocks for memory and product-term logic, making it useful for glue logic, bus bridging, protocol processing, and custom coprocessing tasks. The EP20K60EFC324-3N sits in the hierarchy FPGA > programmable logic device > integrated circuit. Key features of the EP20K60EFC324-3N include 2,560 logic elements, 196 user I/O pins, and 60K typical gates. The 324-FBGA package measures 19 mm x 19 mm and the device is supplied in bulk packaging. The -3 speed grade provides an internal operating frequency of 182 MHz, while the MultiCore architecture allows simultaneous implementation of register-based logic, memory, and product-term logic. The 1.8 V core minimizes dynamic power for mid-density communications, industrial, and instrumentation applications. The EP20K60EFC324-3N uses Altera's MultiCore architecture, combining look-up-table based logic elements with embedded system blocks for dual-port RAM, FIFO, and product-term functions. This heterogeneous fabric allows designers to reduce board-level part count by integrating small memory functions and combinatorial logic in one FPGA. The device is configured from an EPC configuration device or a processor after power-up. As part of the APEX 20KE family, it supports a 3.3 V or lower I/O environment and provides manageable timing closure through the Quartus II development environment. The 0.22 um process balances density and performance at a 1.8 V core voltage. Typical applications for the EP20K60EFC324-3N include telecom interface bridging, network line-card control logic, industrial sensor aggregation, and test instrumentation digital front ends. Its 196 I/Os are sufficient to connect a 32-bit microprocessor bus, SRAM, and multiple UART/SPI interfaces. The 2,560-element logic array can implement UARTs, FIFOs, parity and CRC checkers, or a soft-core state machine without an external CPLD. When designing the EP20K60EFC324-3N into a board, verify power-supply sequencing and decoupling. The core must be held within 1.71 V to 1.89 V, and each VCC pin should be bypassed with low-ESR ceramic capacitors close to the ball pads. Because the FPGA is volatile, provide a configuration source and reset strategy for reliable start-up. This page aggregates verified distributor specifications, speed-grade ordering options, and practical design notes that are not always visible in the Altera APEX 20K datasheet, including availability through Rochester Electronics and drop-in speed-grade variants in the same 324-FBGA footprint. Use this information to compare sourcing choices before committing a new PCB.
EP20K60EFI144-2X - APEX 20KE FPGA 60K Gates 144-FBGA | Altera
The Altera (now Intel) EP20K60EFI144-2X is a member of the APEX 20KE programmable logic device family that delivers 60,000 typical gates in a 144-pin FineLine BGA (LBGA) package. It integrates LUT-based logic, product-term logic, and embedded memory blocks into a MultiCore architecture, enabling true system-on-a-programmable-chip (SOPC) integration for register-intensive data-path and datapath-control designs. The -2X speed grade with 2.41 ns propagation delay targets designs that need deterministic logic timing at 1.8 V core. A field-programmable gate array (FPGA) is a semiconductor IC containing configurable logic blocks (CLBs), programmable interconnect, and dedicated I/O cells that allow engineers to implement arbitrary digital logic through software-defined configuration bitstreams. FPGAs sit hierarchically between ASICs (which offer higher density but are fixed at tape-out) and CPLDs (which are smaller and non-volatile). The APEX 20KE family specifically combines LUT logic, product-term logic, and embedded system blocks (ESBs) - useful for memory-intensive designs needing mixed datapath and control logic on a single die. Key features include 60,000 typical gates with 2,560 logic elements (LEs), a 1.8 V core supply (range 1.71 V to 1.89 V), 4 dedicated inputs plus 93 user I/O lines (total 144 terminals), 200 MHz internal operation, and 0.22 µm CMOS process technology. The 144-pin FineLine BGA package provides high board density while supporting LVDS I/O. The -2X industrial speed grade is rated for -40 °C to +85 °C ambient operation. The MultiCore architecture partitions each logic element between LUT-based register-intensive logic and product-term logic for wide combinational functions, while embedded system blocks provide dual-port RAM and CAM. This is well-suited to designs requiring on-chip memory buffering alongside high-speed glue logic. The device supports in-system programmability via IEEE 1149.1 (JTAG) boundary-scan and configuration via serial or parallel PROM. Typical applications include telecommunications backplane glue logic, industrial control and instrumentation datapaths, PCI bridge designs, and ASIC prototyping. The 93 user I/Os make it suitable for memory-interface and parallel-bus bridging, while LVDS support allows direct connection to high-speed LVDS peripherals.

When designing with this part, note that the APEX 20KE family is NRND/EOL in most channels; verify supply-chain availability and check Intel FPGA product longevity. Use the Quartus II (legacy) or Quartus Prime programmer flow for configuration bitstream generation, and respect 1.8 V core supply tolerance for power-rail sequencing. This page synthesizes distributor pricing, drop-in APEX 20KE alternatives in the same FBGA-144 footprint, and practical design notes that complement the official Altera APEX 20KE datasheet (A-DS-APEX20KE-02).
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.

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.

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.

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.

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.

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.

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. This page synthesizes distributor pricing, pin-compatible alternatives from the same APEX-20KE family, and practical legacy-design notes not found in the original datasheet alone.

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.

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.

EP2A15B652C7 - APEX II FPGA, 1.5M Gates | Intel | Legacy PLD
The Intel EP2A15B652C7 is a member of the APEX II family of programmable logic devices (PLDs) manufactured on a 0.18-micron CMOS process, offering up to 1.5 million typical gates in a 652-ball BGA package. 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.
