EP20K30EFC324-1

EP20K30EFC324-1 - APEX-20K 30KLE FPGA 324-FBGA | Altera

The Altera (Intel) EP20K30EFC324-1 is a member of the APEX-20KE family of field-programmable gate arrays (FPGAs) integrating 30,000 typical logic elements (30KLE), 24,576 RAM bits, and 128 maximum user I/O pins in a 324-ball FineLine BGA package. The part operates from a 1.71 V to 1.89 V core supply and is rated for commercial temperature grades. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the designer can configure after manufacture. APEX-20K belongs to the PLD -> CPLD/FPGA -> SRAM-based FPGA -> programmable logic IC hierarchy, providing system-on-a-programmable-chip (SOPC) integration. The MultiCore architecture of APEX-20KE combines look-up table (LUT) logic, product-term logic, and embedded memory blocks in one fabric. Key features of the EP20K30EFC324-1 include 30,000 typical logic elements (LEs), 24,576 total RAM bits, 128 maximum user I/O, and 1.8 V core operation. The device supports LVDS I/O and embeds an enhanced clock management capability with up to four phase-locked loops (PLLs). The 324-FBGA package is a 19 mm x 19 mm FineLine BGA suitable for high-density PCB designs and high-speed signal fan-out. From an architectural perspective, the APEX-20KE family uses a four-level hierarchy (Logic Array, MegaLAB, Logic Element, Embedded System Block) and embedded array blocks (EABs) for memory and product-term logic. Hot-socketing and JTAG boundary-scan testability are supported. The fabric is configured by an industry-standard serial configuration device. Typical applications include telecommunications line cards, ASIC prototyping, glue-logic consolidation, DSP co-processing front-ends, and industrial control boards where the 30KLE density is appropriate. The 324-FBGA footprint is appropriate for high-I/O designs (128 user I/O). When designing with this part, confirm the configuration scheme (passive serial, passive parallel synchronous, passive parallel asynchronous, JTAG) and use Altera Quartus II for synthesis and place-and-route.

EP20K30EFC324-1X

EP20K30EFC324-1X - APEX 20KE FPGA, 30K Gates, 324-BGA | Intel / Altera

The Intel (formerly Altera) EP20K30EFC324-1X is a member of the APEX 20KE programmable logic device family, providing 30,000 typical gates, 1,200 logic elements (LEs), and 24,576 bits of embedded SRAM in a 324-ball FineLine BGA (FBGA, 19x19 mm) package. It is built on a 0.22 µm CMOS process with a 1.71 V–1.89 V core supply and supports LVDS I/O, MultiCore™ architecture integrating LUT logic, product-term logic, and embedded memory blocks for system-on-a-programmable-chip (SOPC) designs. A field programmable gate array (FPGA) is a reprogrammable semiconductor device whose logic function is defined by the customer after manufacture, unlike an ASIC whose function is fixed at tape-out. FPGAs sit at the intersection of microcontrollers and custom silicon in the broader programmable logic taxonomy: PLD -> CPLD -> FPGA -> SoC FPGA. APEX 20KE was the first family to embed dedicated LVDS interfaces, dual-port RAM, and content-addressable memory (CAM), making it well-suited for high-speed datapath and interface bridging applications in telecom, networking, and DSP prototyping. Key features of the EP20K30EFC324-1X include 128 maximum user I/O pins, four dedicated inputs, four phase-locked loops (PLLs), up to 24576 RAM bits organized as embedded system blocks (ESBs), and a tPD (pin-to-pin logic delay) of 1.91 ns. The device supports in-system programmability via the passive serial, JTAG, and Altera Fast Passive Parallel configuration interfaces, enabling rapid prototyping and field upgrades without removing the part from the board. The APEX 20KE MultiCore™ architecture combines lookup-table (LUT) logic for register-intensive functions with embedded product-term logic for wide combinatorial paths, all interconnected by a four-level hierarchical routing network called the DirectDrive™ fabric. This mixed-logic approach lets designers place time-critical state machines in product-term logic while implementing wide datapath arithmetic in LUTs, optimizing both speed and density on the same die. Typical applications include telecom line-card glue logic, custom peripheral bus bridges, DSP preprocessing front-ends, and industrial control state machines. The 1.8 V core combined with LVDS-capable I/O also makes the part attractive for legacy parallel-bus interfaces and PCI bridge designs where a modern SoC FPGA would be oversized for the task. When designing with the EP20K30EFC324-1X, pay close attention to I/O bank grouping because LVDS pairs require matched differential trace lengths of within 200 mil (≈5 mm). Decoupling must include at least eight 0.1 µF ceramics distributed around the BGA perimeter, and the configuration scheme (typically passive serial with an EPC2 or EPC4 configuration PROM) should be validated against Quartus II programmer files before tape-out. The APEX 20KE family is in last-time-buy status; long-lifecycle designs should qualify second-source logic carefully. This page synthesizes distributor pricing, package-same drop-in alternatives from the same Altera/Intel APEX 20KE family, and practical design notes not found in the original datasheet alone.

EP20K30EFC324-2X - APEX-20KE FPGA 30K Gates 324-FBGA | Altera

The Altera (Intel) EP20K30EFC324-2X is a member of the APEX-20KE Field Programmable Gate Array family, delivering approximately 30,000 system gates with 1,200 logic elements and 24,576 RAM bits in a 324-ball FineLine BGA package. Fabricated on a 0.22 micrometer process and operating from a 1.71V to 1.89V core supply (1.8V nominal), the device integrates embedded memory and product-term logic in a single MultiCore architecture, targeting system-on-a-programmable-chip (SOPC) designs. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose digital logic functionality is defined after manufacturing through a configuration bitstream. Unlike a CPLD, an FPGA uses an array of small look-up tables (LUTs), flip-flops, programmable interconnect, and embedded block RAM. The APEX-20KE family extends this with embedded product-term logic for register-intensive glue functions. Within the broader semiconductor hierarchy, an FPGA sits above CPLDs and below ASICs in terms of integration density, offering high logic capacity, reprogrammability, and embedded memory for digital signal processing, bus interface, and glue-logic roles. Key specifications of the EP20K30EFC324-2X include 30K typical gates, 1,200 logic elements, 24,576 total RAM bits, a 2.69 ns pin-to-pin delay, 128 maximum user I/O pins, and up to 4 phase-locked loops (PLLs) for clock management. The device supports LVDS I/O and multiple I/O standards, and it is supplied in a 324-pin FineLine BGA (19x19 mm) package suitable for high-density PCB designs. The -2X speed grade indicates enhanced performance over the standard -2 grade at extended temperature. The MultiCore architecture combines LUT-based logic, product-term logic, and embedded memory blocks, allowing designers to map register-intensive functions to product-term arrays and datapath functions to LUTs. Embedded RAM supports single- and dual-port operation, enabling on-chip FIFOs and buffering without external memory for moderate workloads. This architectural balance was distinctive for its era, prefiguring the heterogeneous fabric used in modern SoC FPGAs. Typical applications include telecommunications line cards, industrial control, glue-logic and bus bridging on legacy systems, ASIC prototyping, and embedded DSP preprocessing. The wide I/O count makes the device suitable for parallel datapaths, memory controllers, and multi-protocol bridge functions where 128 user I/O pins are required. Designers should note that the APEX-20KE family is a mature, NRND/EOL-prone product line; verify current lifecycle status with Intel before committing to new designs. The 1.8V core supply and 324-FBGA package demand multi-layer PCB design with controlled-impedance routing and careful power-plane decoupling. Configuration data must be loaded from a PROM or flash memory at power-up. This page consolidates distributor pricing, drop-in same-package alternatives within the APEX-20KE family, and practical FPGA design notes not found in the manufacturer datasheet, providing a one-stop reference for engineers specifying the EP20K30EFC324-2X.

The Altera (now Intel) EP20K30EFC324-3 is a member of the APEX 20KE programmable logic device family, integrating 30,000 typical gates (look-up table logic), 128 macrocells, 24,576 RAM bits, and approximately 1,200 logic elements into a single MultiCore architecture device. It is housed in a 324-ball FineLine BGA package and operates from a 1.71 V to 1.89 V core supply (1.8 V nominal). The -3 speed grade delivers internal timing that supports the targeted 160 MHz clock frequency class of the APEX 20KE family, making it appropriate for system-on-a-programmable-chip (SOPC) designs. An FPGA (Field-Programmable Gate Array) is a programmable logic device that combines configurable logic blocks (LUTs), programmable interconnect, and embedded memory. The APEX 20KE family in particular integrates look-up table logic for register-intensive functions, product-term logic for arithmetic paths, and embedded memory blocks, sitting in the broader hierarchy: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit. APEX 20KE was Altera's first SOPC-integrating PLD family, widely used as a precursor to the modern Cyclone/Stratix families. Key features include 128 macrocells, 24,576 total RAM bits, 120 user I/O pins (per published catalog data), LVDS I/O support, in-system programmability via JTAG, and MultiCore architecture for combining LUT-based and product-term logic on the same die. The 324-FBGA package provides a compact 19 mm x 19 mm footprint suitable for high-density boards, with a peak reflow compliance suitable for standard SMT assembly. The device is implemented on a 1.8 V, 0.18 micrometer CMOS process, which balances low power consumption with sufficient drive strength for LVDS signaling. The integrated memory blocks permit FIFOs, dual-port RAM, and CAM functions without external SRAM, simplifying SOPC integration. I/O banks support a mix of single-ended and LVDS I/O standards, enabling high-speed chip-to-chip links. The MultiCore architecture allows LUT logic and product-term logic to be mixed freely, which is helpful for datapath/control hybrid designs. Typical applications include telecommunications line cards, industrial control and automation, ASIC prototyping, glue logic replacement, video/Imaging pipeline front-ends, and legacy SOPC designs where the APEX 20KE was the original Altera solution. Its LVDS support also makes it suitable for backplane interfacing and high-speed serial-to-parallel conversion. When designing with this part, ensure JTAG chain integrity, follow Altera's recommended decoupling scheme on each power pin, and confirm Quartus version compatibility for the APEX 20KE device family. Note that this device is in mature lifecycle status - new designs should consider Cyclone or MAX families.

EP20K30EFI144-2X

EP20K30EFI144-2X - APEX 20KE FPGA 1200 Cells 93 I/O 144-BGA | Intel

The Intel EP20K30EFI144-2X is a member of the APEX 20KE family of Field Programmable Gate Arrays (FPGAs), delivering 1200 logic elements, 24576 RAM bits, and 93 user I/O pins in a 144-ball FineLine BGA package. The device is fabricated on a 0.22 µm CMOS process, operates from a 1.8 V core supply, and is rated for industrial temperature ranges. The 'EFI144' package suffix denotes an Enhanced (E) industrial-grade part in a 144-pin FineLine BGA. What is an APEX 20KE FPGA? The APEX (Advanced Programmable Element Matrix) 20KE family is a multi-vendor-compatible programmable logic architecture combining look-up table (LUT)-based logic elements with embedded system blocks (ESBs) that double as RAM, ROM, or product-term logic. In the broader taxonomy, an FPGA is a programmable logic device (PLD) within the semiconductor integrated circuit family, sitting between ASICs and discrete logic in flexibility and density. APEX 20KE parts were widely deployed in telecom, networking, and DSP applications in the late 1990s and early 2000s. Key features of the EP20K30EFI144-2X include 1200 logic elements, 192 macrocells, 24576 embedded RAM bits, 93 maximum user I/O, and 1.8 V core operation. The device supports in-system programmability via IEEE 1149.1 JTAG, multi-vendor I/O standards (LVTTL, LVCMOS, PCI, GTL+, SSTL, HSTL), and dedicated clock and PLL resources. The 144-ball FineLine BGA package provides a compact footprint while preserving sufficient I/O count for typical glue-logic and DSP datapath designs. Architecturally, the APEX 20KE combines a MegaLAB structure with embedded system blocks, allowing designers to trade logic density against memory width. The LUT-based logic elements support cascade chains for wide datapaths, while the ESBs can be configured as dual-port RAM or FIFO buffers. Hardware multipliers are not present in the 20KE family, so DSP functions are typically implemented using LUT-based multiplication or external co-processors. Typical applications for the EP20K30EFI144-2X include telecom interface cards, protocol bridging logic, low-density DSP preprocessing, industrial control state machines, and PCI bus interface glue logic. The industrial temperature grade makes it suitable for factory automation and outdoor telecom equipment. Note that the APEX 20KE family is end-of-life; modern Cyclone IV/V or Lattice ECP5 devices are recommended for new designs. When designing with this part, plan the I/O bank VCCIO assignments carefully because mixed-voltage standards require multiple supply rails. The Quartus II design tool (legacy versions supporting APEX 20KE) is required for bitstream generation. JTAG programming via a ByteBlaster or USB-Blaster download cable is the standard configuration path.

EP20K30EQC208-1

EP20K30EQC208-1 - APEX 20KE FPGA 1.8V 208-PQFP | Altera

The Altera EP20K30EQC208-1 is an APEX-20KE field-programmable gate array (FPGA) from the legacy Altera APEX 20K 1.8-V family, integrating 1,200 logic elements, 24,576 RAM bits, and 125 user I/O in a 208-pin BFQFP/PQFP package. It operates from a 1.71 V to 1.89 V core supply and uses the MultiCore architecture that combines look-up table (LUT) logic, product-term logic, and embedded memory. The EQC208 suffix denotes the 208-pin quad flat pack package and the -1 speed grade. An FPGA is an integrated circuit whose logic fabric can be reprogrammed after manufacturing to implement arbitrary digital hardware. Unlike fixed-function ASICs or simple CPLDs, designers configure LUTs, flip-flops, routing resources, and I/O pins to create processors, controllers, protocol engines, or signal interfaces. The EP20K30EQC208-1 is a representative 30K-gate-class FPGA; within a system hierarchy it functions as a programmable logic device, programmable gate array, or system-on-programmable-chip building block, often sitting between microprocessor glue logic and complex custom logic. Understanding this category is important for legacy system repair, reverse-engineering, and replacement decisions, because APEX 20KE devices belong to the early low-voltage 1.8-V FPGA generation that led to later Altera/Intel families. Key features include the -1 speed grade, the fastest timing option for this APEX 20KE 208-pin part, 24,576 embedded RAM bits for FIFOs or small buffers, and 125 configurable user I/O pins. The MultiCore architecture is notable because it integrates LUT-based FPGA logic with product-term logic normally found in CPLDs, allowing efficient state machines and decode logic without consuming extra logic cells. According to the published specification snapshot, the device uses 0.22-um CMOS technology and a 1.8-V core supply, which is lower than earlier 2.5-V/3.3-V programmable logic families and helps reduce dynamic power in legacy systems. At the architectural level, the 30K-gate capacity in Altera APEX terminology corresponds to approximately 1,200 logic elements. The 208-pin package gives designers enough I/O for moderate bus interfaces, memory control, and expansion. The APEX-20KE family also supports JTAG-based configuration and can be used with Altera configuration devices. Exact LAB, EAB, PLL, and clock-management block counts were not included in the verified source snippets, so engineers should consult the full APEX 20KE family datasheet for detailed architecture guidance before beginning a design. Typical applications include industrial control I/O, legacy bus bridging, video/imaging processing, telecommunication line-card logic, and obsolete-board repair. This FPGA is often chosen when no modern pin-compatible device exists and the original APEX 20KE logic implementation must be preserved. With its 24,576 RAM bits and 125 I/O pins, it is suited to moderately sized data interfaces, custom state machines, and capture/control logic in installed equipment. When designing with this device, conservatively account for the 1.8-V core supply and multiple I/O supply rails. Place decoupling capacitors near every core and I/O supply pin, and respect the thermally enhanced BFQFP package height information given in the Altera Device Package Information Data Sheet. Because the part is no longer high-volume production, verify the date code, lead finish, and available stock before finalizing a BOM. This page synthesizes verified distributor listings, package and family comparisons, and practical legacy-system guidance that are not consolidated in the Altera datasheet, helping engineers quickly validate availability, speed-grade alternatives, and design constraints for the EP20K30EQC208-1.

EP20K30EQC208-2 - APEX 20KE FPGA, 30K Gates, 208-PQFP | Intel

The Intel (formerly Altera) EP20K30EQC208-2 is a member of the APEX 20KE family of Field Programmable Gate Arrays (FPGAs) fabricated on a 1.8 V CMOS process and housed in a 208-pin Power Quad Flat Pack (PQFP/BFQFP) package. The device integrates 30,000 typical gates, 1,200 logic elements, 24,576 RAM bits of embedded memory, and a MultiCore architecture combining look-up-table (LUT) logic, product-term logic, and embedded memory blocks on a single die. An FPGA (Field Programmable Gate Array) is a programmable logic device that contains an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, allowing engineers to implement arbitrary digital logic that would otherwise require multiple discrete MSI/LSI components. APEX 20KE sits in the high-density programmable-logic hierarchy: programmable logic device (PLD) -> CPLD/FPGA -> high-density SRAM-based FPGA -> system-on-a-programmable-chip (SOPC) platform. APEX 20KE was the industry's first PLD family to integrate LUT logic, product-term logic, and embedded memory into one MultiCore architecture, enabling SOPC integration on a single chip. Key features of the EP20K30EQC208-2 include 125 user I/O pins, 4 dedicated inputs, 24576 bits of embedded SRAM, a maximum clock frequency of 160 MHz, and a pin-to-pin propagation delay of 2.69 ns. The device operates from a 1.71 V to 1.89 V core supply with LVDS-compatible I/O support. Hot-socketing support, in-system programmability via the IEEE 1149.1 JTAG interface, and built-in PCI compliance make the part suitable for plug-in card designs. The MultiCore architecture blends MegaLAB structures that group 16 Logic Elements with 1 Embedded System Block, allowing designers to mix register-intensive datapath logic, product-term control logic, and dual-port RAM within the same array. The 2.69 ns speed grade (-2 suffix) is the mid-tier timing bin; slower -1 and faster -3 grades also exist in the family. Typical applications include telecommunications interface cards, industrial control and factory automation, PCI bridge logic, network switching fabric glue logic, and legacy system upgrades where high-density programmable logic is required. The wide PQFP-208 footprint and SRAM-based configuration also make it well suited to evaluation platforms and ASIC prototyping. When designing with EP20K30EQC208-2, plan a stable 1.8 V core rail with bulk decoupling near the package and 0.1 uF ceramics at each supply pin; SRAM-based FPGAs require all supplies present before configuration is attempted, so a proper power-on-reset and CONFIG_DONE monitoring are essential. Operating junction temperature must stay within the industrial range, and JTAG programming requires the Altera (now Intel) Quartus II / Quartus Prime toolchain for bitstream generation.

EP20K30ETC144-1 - APEX-20KE FPGA, 30K Gates, 144-LQFP | Altera

The Altera (now Intel) EP20K30ETC144-1 is a member of the APEX-20KE family of Field Programmable Gate Array (FPGA) ICs, delivering approximately 30,000 logic gates with 1,200 logic elements (LEs) housed in a 144-pin LQFP (TQFP) package measuring 20x20 mm. It supports a maximum of 92 user I/O pins and operates from a 1.71 V to 1.89 V (1.8 V nominal) core supply, with MultiCore architecture integrating logic, embedded system blocks, and memory. A field-programmable gate array (FPGA) is a semiconductor device built around a matrix of configurable logic blocks (CLBs), embedded memory blocks, and programmable interconnect that can be reconfigured by the designer after manufacture. APEX-20KE belongs to the hierarchical PLD family: PLD -> CPLD -> FPGA -> programmable logic device -> logic IC. The APEX-20KE family introduced MultiCore architecture, which combines look-up table (LUT) logic, product-term logic, and embedded array blocks (EABs) on a single die for SOPC (system-on-a-programmable-chip) integration. This makes the EP20K30ETC144-1 suitable for designs that mix glue logic, DSP functions, and small memory subsystems. Key features include 192 macrocells, 92 user I/Os, 4 dedicated inputs, a maximum internal frequency of 160 MHz, and 0.22 micrometer CMOS process technology. The device is built on a CMOS process with an LVTTL/LVCMOS compatible I/O standard. The 144-LQFP (also referenced as PQFP144, TQFP-144, or LFQFP-144 with 0.5 mm pitch) provides a low-cost, gull-wing surface-mount option for moderate-density designs where fine-pitch BGA packaging is not required. Typical applications include communications glue logic, industrial control interfaces, custom peripheral bridges, low-density data-path acceleration, and legacy system upgrades where a programmable logic replacement is needed. The industrial operating temperature range (0°C to 85°C) and 1.8 V core supply make it compatible with mixed-voltage system boards from the early 2000s. When designing with this device, ensure 1.8 V core and 3.3 V (or 2.5 V) I/O bank supplies are decoupled with 0.1 uF and 10 uF capacitors placed close to the supply pins. Configuration can be performed via JTAG or passive serial using a MAX-series CPLD or EPC-series configuration device. Use the Altera (Intel) Quartus design toolchain for compilation, fitting, and timing analysis. Note that the APEX-20KE family has been classified NRND by Intel; design teams should evaluate Cyclone or MAX-series parts for new designs.

FPGAs sit in the broader taxonomy of programmable logic (PLD -> CPLD -> FPGA -> SoC FPGA) and are used to implement arbitrary digital logic, glue logic, DSP pipelines, and full processor subsystems when the silicon is large enough. The APEX-20KE family is a MultiCore architecture that combines Look-Up Table (LUT)-based logic with embedded memory blocks (ESBs) for high-density, system-on-a-programmable-chip (SOPC) designs. Key features include 1,200 logic elements (cells), 24,576 total RAM bits distributed across embedded system blocks, 92 user I/O pins, and 113,000 maximum system gates. The device supports in-system programmability via SRAM configuration, hot-socketing, and multi-voltage I/O. The 144-LQFP package uses a 0.5 mm pitch gull-wing lead frame and is suitable for cost-sensitive, moderate-density designs that do not require the fine-pitch or high-speed transceivers of newer families. The APEX-20KE architecture combines fine-grain LUTs with coarse-grain ESBs, allowing efficient implementation of wide datapath functions, multipliers, and small FIFOs. The 0.22 µm CMOS process is mature and supports the 1.8 V core voltage with 3.3 V/5 V-tolerant I/O via banked VCCIO pins (referenced in the datasheet), enabling direct interface to legacy TTL/CMOS peripherals without external level shifters. Typical applications include communications glue logic, industrial control interfaces, video and image processing front-ends, legacy ASIC prototyping, and educational development platforms. The 92 I/Os in a 144-LQFP package balance logic capacity with board-level routability for prototype through small-volume production runs. When designing with this device, plan the configuration scheme (EPC configuration device or microprocessor-driven passive serial/parallel), respect the I/O bank VCCIO grouping shown in the pinout, and ensure the Quartus II design tool (or MAX+PLUS II for legacy flows) supports the EP20K30E device variant.

EP20K30ETC144-2N - APEX 20K FPGA 30K Gates 144-TQFP | Intel

The Intel EP20K30ETC144-2N is a member of the APEX 20K family of programmable logic devices, integrating 30,000 gates, 1,200 logic elements (cells), and 92 user I/Os in a 144-pin TQFP (Thin Quad Flat Pack) surface-mount package. The device operates from a 1.8 V core supply with 0.22 µm CMOS process technology and is rated for an internal frequency of 160 MHz (435 MHz according to alternate catalog data) with 1.68 ns propagation delay. The 'E' suffix in the part number denotes an enhanced commercial operating temperature range of 0 °C to +85 °C. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device that combines the density of a gate array with field-programmability via an SRAM-based configuration cell array. The APEX 20K family introduced MultiCore architecture, integrating look-up tables (LUTs), product-term logic, and embedded system blocks (ESBs) for on-chip memory, allowing system-on-a-programmable-chip (SOPC) integration. FPGAs sit at the top of the programmable logic hierarchy (CPLD -> FPGA -> SoC FPGA) and serve applications requiring high gate counts and parallel DSP-style processing. Key features include 30K equivalent gates, 1,200 logic cells, 192 macro cells, embedded memory via ESBs, JTAG boundary-scan support, multi-voltage I/O standards, and in-system programmability via SRAM configuration. The 144-pin TQFP package provides gull-wing leads for reflow soldering, suitable for cost-sensitive industrial, telecom, and embedded designs. The MultiCore architecture integrates LUTs and product-term logic in a unified fabric, allowing each logic element to be configured for either combinational or sequential logic. Embedded System Blocks provide dual-port RAM with up to 32 Kbits per block, enabling on-chip FIFOs and buffers. The 1.8 V core supply reduces dynamic power compared to older 5 V FPGAs. Typical applications include telecommunications glue logic, industrial control interfaces, custom bus bridges, and prototyping of ASIC designs. The 92 user I/Os allow direct interfacing to parallel buses, memory, and standard peripherals. Compared to modern Cyclone or Spartan families, the APEX 20K is legacy technology typically used for maintaining installed equipment. When designing with this device, confirm availability through Intel/Altera authorized distributors as APEX 20K parts are largely NRND (Not Recommended for New Designs). Design tooling requires the legacy Quartus II 4.2 or earlier MAX+PLUS II environment. The 144-TQFP footprint has a larger body than modern FPGAs, so mechanical compatibility with current 32-pin or 64-pin TQFPs cannot be assumed.

EP20K30ETC144-2X - APEX 20KE FPGA, 30K Gates, 92 I/O, 144-LQFP | Intel

The Intel (Altera) EP20K30ETC144-2X is a member of the APEX 20KE family of Field Programmable Gate Arrays (FPGAs) that integrates 192 macrocells, 30,000 typical gates, and 1,200 logic elements in a 144-pin LQFP (E-type temperature, -2 speed grade) surface-mount package. An FPGA (Field-Programmable Gate Array) is a reprogrammable semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells, allowing engineers to implement custom digital circuits without the cost or lead time of an ASIC. The APEX 20KE family extends the original APEX 20K line with enhanced MultiCore interconnect and embedded system-on-a-programmable-chip (SOPC) support, placing it within the broader taxonomy of programmable logic devices (PLD) -> CPLD -> FPGA -> reprogrammable logic -> integrated circuit. Key features of the EP20K30ETC144-2X include 24,576 typical logic elements / system gates, 1,200 logic cells, 92 user I/O pins, internal frequency support up to 160 MHz, and a propagation delay of approximately 1.68 ns. The device operates from a 1.8 V core supply and supports multiple I/O standards via dedicated I/O banks. Its MultiCore architecture combines Look-Up Table (LUT)-based logic with embedded array blocks (EABs) for memory and arithmetic functions. The MultiCore architecture allows designers to allocate silicon resources between fine-grained LUT logic and coarse-grained EAB memory blocks, optimizing the device for DSP, datapath, or control-plane applications. Each EAB can be configured as RAM, ROM, or multiplier, giving the APEX 20KE flexibility that pure LUT-only FPGAs of the era lack. The 1.8 V core and 1.5 V internal supply rails are generated on-chip from the external VCCINT pin, simplifying power-tree design. Typical applications include telecommunications line cards, industrial control and glue logic, PCI bridge interfaces, and legacy system upgrades where pin-compatible migration to newer FPGA families is not required. The 144-pin LQFP package is footprint-friendly for through-hole-replacement designs and breadboard-friendly prototypes. The device is suitable for both volume production and end-of-life replacement scenarios, given its mature APEX 20KE tool chain (Quartus II versions prior to 13.0). When designing with the EP20K30ETC144-2X, ensure your Quartus II tool chain version supports the APEX 20KE device family and that the JTAG chain matches the 10-pin Altera header pinout. EAB-based memory blocks must be instantiated via MegaWizard Plug-Ins or LPM library calls, and unused I/O pins should be configured as tri-stated inputs with weak pull-ups to minimize in-rush current.

EP20K30ETC144-3N - 30K Gates APEX-20KE FPGA, 144-TQFP | Altera/Intel

The Intel (formerly Altera) EP20K30ETC144-3N is an APEX-20KE family Field-Programmable Gate Array (FPGA) integrating 30,000 system gates, 1,200 logic elements, and 24,576 RAM bits in a 144-pin TQFP (also referenced as 144-LQFP) package. The 'E' suffix denotes the 1.8V core enhanced architecture, 'TC' indicates the commercial TQFP package with 92 user I/Os, and the '-3N' speed grade targets 1.68 ns propagation delay with industrial-grade thermal screening. The device is fabricated on a 0.22 µm CMOS process and is supported by the legacy Altera Quartus design tool chain for SOPC (System-On-a-Programmable-Chip) integration. What is an APEX-20KE FPGA? An APEX-20KE device is a programmable logic device (PLD) that combines look-up-table (LUT)-based logic, embedded system blocks (ESBs) that double as either product-term logic or dual-port RAM, and a MultiCore interconnect fabric. In the broader taxonomy, an APEX-20KE falls under FPGA -> programmable logic -> logic IC -> integrated circuit. The 'KE' variant improved upon the original APEX-20K by adding higher-speed I/O standards (LVTTL, LVCMOS, PCI, GTL+, SSTL-2/3, HSTL) and a more deterministic routing architecture aimed at communications and DSP backplane designs of the early 2000s. Key specifications include 1,200 logic elements, 24,576 embedded RAM bits configurable as 32×18 dual-port blocks, 192 macrocells, 92 user I/Os (with 4 fast-row clocks), 1.68 ns pin-to-pin propagation delay (speed grade -3), and a 435 MHz internal performance figure. The 1.8V core is supported by MultiVolt I/O drivers that allow the I/O banks to operate at 1.8V, 2.5V, or 3.3V, simplifying mixed-voltage interfacing to legacy ASICs and processors. The APEX-20KE MultiCore architecture combines fine-grained LUTs with coarse-grained ESBs, allowing designers to instantiate distributed RAM, ROM, FIFOs, and wide datapath arithmetic blocks without consuming glue logic. The deterministic interconnect minimizes timing closure iteration versus the original APEX-20K, which is critical for protocol bridges such as UTOPIA, POS-PHY, and RapidIO that were common when the family shipped. Typical applications include telecommunications line-card glue logic, serial-protocol bridges (UTOPIA/POS-PHY Level 2/3), industrial motor-control pre-processing, and military/aerospace retrofits of legacy designs. With 24 Kbits of block RAM and 92 I/Os, the EP20K30E is well suited to small-format coprocessors, custom bus controllers, and PCI target interfaces in CompactPCI or VME backplanes. A key design consideration is that the APEX-20KE family is mature and is now supported mainly for legacy system sustainment. New designs should evaluate Cyclone or MAX series devices unless a strict pin-compatible drop-in into an existing TQFP-144 PCB is required. Power estimation requires the Quartus PowerPlay early-power estimator, and unused I/O banks should be tied to a defined logic level to avoid leakage.

The Altera (now Intel) EP20K400BC652-1 is a member of the APEX-20K family of programmable logic devices (PLDs) that integrates system-on-a-programmable-chip (SOPC) functionality into a single high-density FPGA IC, providing 400K gates of logic capacity with 502 user I/O pins housed in a 652-ball BGA package. An FPGA (Field Programmable Gate Array) is a programmable logic device whose logic resources, routing, and I/O can be configured by the end user after manufacture. The APEX-20K family is a high-density PLD family incorporating MultiCore architecture that integrates look-up table (LUT) logic, product-term logic, and embedded memory blocks on a single die. FPGAs sit within the broader hierarchy: programmable logic device (PLD) -> field programmable gate array (FPGA) -> SRAM-based high-density FPGA -> SOPC-class integrated FPGA. They are typically used for glue logic, custom datapaths, bus interfaces, DSP, and prototype ASIC development. Key features of the EP20K400BC652-1 include 1664 macrocells of logic, a maximum of approximately 212,992 bits of embedded RAM, a propagation delay of 2.5 ns, and a supply voltage of 1.71 V to 1.89 V (2.5 V core supply standard). The device operates across the commercial temperature range of 0 °C to 85 °C and is delivered in a thermally enhanced 45 x 45 mm 652-BGA package suitable for high-density board designs. The APEX-20K architecture combines a fine-grained LUT fabric with embedded array blocks (EABs) that act as dual-port RAM, ROM, or FIFO memory. This MultiCore integration allows the EP20K400 to be partitioned between register-intensive datapath logic and block-memory functions in the same device, eliminating the need for an external memory companion in many designs. Typical applications include high-speed telecommunications interface cards, custom bus bridges, DSP pre/post-processing, and prototype ASIC emulation. The 502 user I/O count supports wide parallel buses and multiple serial interfaces in a single device. When designing with this part, pay attention to the 1.8 V core supply and the thermally enhanced BGA-652 footprint, which mandates reflow-compatible PCB stack-ups and a sufficient copper area for heat dissipation. Quartus II or MAX+PLUS II software is required for design entry.

The device integrates 502 user I/O pins and operates at a -1 speed grade with 2.5 ns Quad-Pin-Output clock-to-output, making it suitable for high-performance datapath and bus-interface designs. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs) connected via programmable interconnect, surrounded by programmable I/O cells. Modern FPGAs also embed dedicated memory blocks, multiplier/DSP slices, phase-locked loops, and high-speed transceivers. In the system hierarchy, the FPGA sits between discrete logic (CPLDs, gate arrays) and fixed-function ASICs - offering ASIC-class computational density with the time-to-market advantage of in-system reprogrammability. The APEX 20KC family specifically pioneered MultiCore architecture that mixes LUT-based logic, product-term logic, and embedded memory on a single die. Key features of the EP20K400BC652-1V include 502 maximum user I/O, support for multiple I/O standards (LVTTL, LVCMOS, PCI, GTL+, SSTL, LVDS, HSTL, LVPECL via the APEX 20K I/O cell), a core voltage of 1.8 V (VCCINT) with 2.5 V VCCIO supply, and in-system programmability via the IEEE 1149.1 JTAG interface. The device also offers 4 dedicated clock inputs plus dual-purpose clock pins and supports the Altera MultiVolt I/O architecture for mixed-voltage bus interfacing. The EP20K400BC652-1V utilizes SRAM-based configuration cells that must be loaded from an external PROM or controller at power-up. Its MultiCore architecture combines lookup-table logic (for register-intensive functions), product-term logic (for fast arithmetic and decoding), and Embedded System Blocks (ESBs) for on-chip dual-port RAM and FIFO. The FineLine BGA-652 package exposes sufficient I/O to support wide parallel buses and multiple high-speed serial channels. Typical applications include telecommunications line cards, high-speed data acquisition and instrumentation, network routers and switches, ASIC prototyping, DSP co-processing, and PCI/PCI-X bus interfacing. The 652-BGA package is chosen when designs require maximum I/O count and signal-integrity performance. When designing with the EP20K400BC652-1V, designers should plan configuration loading via a serial or parallel EPC device, allocate sufficient decoupling on each VCCINT/VCCIO plane, and verify signal-integrity on the 652-ball BGA using controlled-impedance traces. The -1 speed grade is the slowest tier of the APEX 20K family, so timing closure should be verified in Quartus II before fabrication.

EP20K400BC652-2AA - 16,640-Cell FPGA | Intel | Legacy Logic

Intel EP20K400BC652-2AA is an APEX-20K family field-programmable gate array containing 1,664 LABs/CLBs and 16,640 logic elements/cells. It provides 212,992 bits of total RAM, 502 user I/O, and 1,052,000 gates in a 652-ball BGA package. The device operates from a 2.375 V to 2.625 V supply and is specified over a 0 °C to 85 °C operating-temperature range. An FPGA, or field-programmable gate array, is a semiconductor device whose logic architecture and interconnections are configured after manufacturing. Its hierarchy commonly extends from programmable logic blocks to embedded-memory blocks and general-purpose I/O, then to programmable logic and digital integrated circuits. APEX-20K devices combine programmable logic, memory, and I/O resources for implementing high-density digital systems and custom interface functions. The principal features of EP20K400BC652-2AA are 1,664 LABs/CLBs, 16,640 logic elements/cells, 212,992 total RAM bits, and 502 I/O. The 652-ball BGA package exposes a large number of user-facing connections, while the 2.375 V to 2.625 V supply range supports a defined legacy operating point. These characteristics suit designs where deterministic custom logic, internal storage, and broad parallel interfacing are required. The APEX-20K architecture integrates programmable logic-array blocks, routing resources, memory, and I/O structures into one configurable device. Configuration data determines the implemented Boolean functions, state-machine behavior, datapaths, and interface protocols. Engineering evaluation should therefore include configuration-file compatibility, power estimation, timing closure, pin assignment, and board-level signal integrity rather than relying only on nominal cell count. Typical uses include industrial control logic, telecommunications interface equipment, test and measurement platforms, and legacy digital systems. For example, the 502 I/O can support many parallel control or data lines, while the 212,992 RAM bits can implement buffering, lookup tables, or state-machine storage. The obsolete lifecycle status makes production support and long-term availability important procurement concerns. Designers should verify the exact manufacturer documentation, configuration flow, speed-grade interpretation, and PCB land pattern before reuse. Because the supplied data does not establish a pin-compatible modern successor, replacement should be treated as a board-level migration rather than an assumed direct substitution. This product record combines the verified electrical, structural, and lifecycle data with explicit unknowns, sourcing provenance, comparison guidance, and design cautions to support legacy-component assessment. Prices, where requested, are referenced as of 2026-09-08, and current inventory must be confirmed directly with the supplier.

The APEX-20KC family specifically introduced system-on-a-programmable-chip (SOPC) integration by embedding dedicated memory and product-term logic alongside traditional look-up-table logic, occupying the hierarchy: FPGA → programmable logic device (PLD) → logic IC → integrated circuit → semiconductor. The 652-BGA FineLine package exposes up to 488 user I/O pins for high-bandwidth system integration. Key features of the EP20K400BC652-2V include 16,640 logic elements, 212,992 bits of embedded SRAM organized as ESBs (Embedded System Blocks), 502 maximum user I/O pins, support for LVDS, PCI, and other high-speed I/O standards, and in-system programmability via IEEE 1149.1 JTAG or passive serial configuration. The MultiCore architecture allows time-critical paths to be implemented in product-term logic while data-path operations benefit from LUT-based fabric, optimizing density and speed simultaneously. Architecturally, the device integrates embedded array blocks (EABs) for memory and complex arithmetic functions alongside logic array blocks (LABs) for general-purpose logic, with FastTrack interconnect routing signals across all four quadrants of the die. The 0.22 µm process and 1.8V core supply provide low-power operation relative to earlier 5V PLDs while supporting modern low-voltage I/O standards required by contemporary ASICs and microprocessors. Typical applications include high-speed telecommunications backplane interfaces, DSP co-processing pipelines, custom peripheral controllers, and network protocol acceleration. The large embedded memory and high I/O count make it well-suited for data buffering in communications equipment and for prototyping complex glue-logic designs before ASIC conversion. Design considerations for the EP20K400BC652-2V include thermal management via the 45 mm × 45 mm BGA substrate, multi-rail decoupling for the 1.8V core and 2.5V I/O supplies, and JTAG chain integration for boundary-scan testing. Engineers should consult Altera Quartus design tools for synthesis, place-and-route, and timing closure across the -2V speed grade corner.

EP20K400BC652-2XV - 400K Gate APEX-20KC FPGA 652-BGA | Altera

The Altera EP20K400BC652-2XV is a member of the APEX-20KC Field Programmable Gate Array family, delivering 400,000 system gates, 16,640 logic elements, and 212,992 bits of embedded memory in a 652-ball BGA package. The -2 speed grade combined with the industrial temperature grade makes this device suitable for moderately fast logic designs in harsh thermal environments. An FPGA (Field Programmable Gate Array) is a type of programmable logic device that allows engineers to implement custom digital circuits through configuration rather than fixed silicon. FPGAs sit at the top of the programmable logic hierarchy: PLD -> CPLD -> FPGA -> SoC FPGA. The APEX-20KC family specifically introduced MultiCore architecture that integrates LUT logic, product-term logic, and embedded memory blocks on a single die - an early example of heterogeneous compute on a programmable fabric that enabled SOPC (System-on-a-Programmable-Chip) integration. Key features of the EP20K400BC652-2XV include 502 user I/O pins, 4 dedicated inputs, a 0.22 micrometer CMOS process, and an internal core voltage around 1.8V with 2.5V I/O support. Maximum toggle performance reaches 200 MHz according to distributor summaries, while pin-to-pin delay is specified at 3.1 ns in the PLD timing model. The MultiCore architecture lets designers mix register-intensive LUT logic with product-term logic for glue functions, which was unusual at the time of release. The device supports in-system programming via the IEEE 1149.1 JTAG interface and the Altera serial configuration scheme, allowing board-level configuration without removing the part. The 652-BGA (45x45 mm) package provides ample signal escape for the 502 I/O pins and supports surface-mount reflow assembly on standard FR-4 PCB substrates. Typical applications include telecommunications line cards, industrial motor control, military and aerospace ruggedized systems, medical imaging front-end pre-processing, and DSP co-processing in legacy test equipment. The wide I/O count supports parallel bus architectures such as PCI, HSTL, and LVDS interfaces that were common in late-1990s and early-2000s designs. When designing with this part, ensure the configuration mode (passive serial, JTAG, or parallel) is properly selected via MSEL pins at board power-up. The 652-BGA package requires X-ray inspection for solder joint verification since BGA balls are hidden beneath the package; plan PCB pad design with non-solder-mask-defined (NSMD) pads for best reliability.

EP20K400BC652-3 - APEX 20K 400K Gate FPGA, BGA-652 | Intel

The Intel EP20K400BC652-3 is a member of the APEX 20K family of Complex Programmable Logic Devices (CPLDs) that combines FPGA-like logic density with PLD-style integration, packaged in a 652-ball BGA (BC652) housing 16,640 logic elements, 1,664 macro cells, and 502 user I/Os on a 2.5 V CMOS process. This -3 speed grade part targets designs where the legacy MultiCore architecture, embedded system-on-a-programmable-chip (SOPC) integration, and predictable deterministic timing of APEX 20K silicon remain in service for long-lifecycle industrial, telecom, and test-and-measurement platforms. A CPLD is a non-volatile, instant-on programmable logic device that uses a combination of AND/OR array planes and macro cells to implement combinatorial and registered logic, sitting in the taxonomy between simple PLDs (PAL/GAL) and full FPGAs. The APEX 20K family extends this concept by integrating embedded memory and a lookup-table based logic fabric on a single die, allowing system designers to consolidate glue logic, interface bridges, and small state machines on one programmable device without resorting to a discrete ASIC. Key features of the EP20K400BC652-3 include 16,640 logic elements, 212,992 bits of embedded system memory, 502 user I/Os across 8 I/O banks, 3.6 ns pin-to-pin propagation delay (3 ns internal per the BGA variant datasheet family), 2.5 V core supply, and a 0 to 85 C commercial operating temperature range. The device is configured via the legacy Altera ByteBlaster or MasterBlaster download cable and supports JTAG IEEE 1149.1 boundary-scan for in-system programming and verification. The MultiCore architecture integrates look-up-table (LUT) logic, product-term logic, and embedded memory blocks on one die, enabling designers to choose the optimal implementation for each function. I/O banks support multiple I/O standards including LVTTL, LVCMOS, PCI, and GTL+, allowing flexible mixed-voltage interfacing. The BGA-652 package provides a high ball count suitable for the device's 502 I/O pins plus dedicated clock, configuration, and supply balls. Typical applications for the EP20K400BC652-3 include telecom backplane glue logic, industrial control system bus interfaces, legacy PCI bridge implementations, test-and-measurement equipment controllers, and long-lifecycle avionics upgrades where the APEX 20K footprint is already designed in. The device is also well suited to prototyping and small-volume production where ASIC NRE costs are not justified. When designing with this device, confirm that the Quartus II design software (legacy versions 9.0 or earlier) is available in your tool chain, since the APEX 20K family is no longer supported by current Quartus Prime releases. Verify that your PCB layout accommodates the 1.27 mm pitch BGA-652 footprint with sufficient microvia and dog-bone fanout for reliable assembly.

EP20K400BC652-3V

EP20K400BC652-3V - 400K Gate APEX 20K FPGA, 652-BGA | Intel

The Intel (formerly Altera) EP20K400BC652-3V is a 400,000-gate APEX 20K family Field-Programmable Gate Array (FPGA) with 16,640 logic cells, 212,992 bits of embedded SRAM, and a maximum of 502 user I/Os, packaged in a 652-ball BGA (45 x 45 mm, 1.27 mm pitch). Built on a 0.22 µm CMOS process with a 2.5 V core supply, the device is rated for commercial 0 °C to 85 °C operation and supports LVDS I/O via the APEX 20KE device family extension. A Field-Programmable Gate Array is a semiconductor integrated circuit built from an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, allowing designers to implement arbitrary digital logic that is re-programmable in the field. APEX 20K devices belong to the PLD -> FPGA -> programmable logic -> digital IC hierarchy and were the industry's first PLDs to integrate look-up table (LUT) logic, product-term logic, and embedded memory blocks on a single die — a system-on-a-programmable-chip (SOPC) integration. Key features include the QuadCore / MultiCore architecture that combines register-rich LUT logic for datapath and state-machine functions, product-term logic for fast control paths, and embedded memory (EABs/LUT-RAM) for buffers, FIFOs, and small register files. The -3V speed grade targets ~167 MHz internal operation. The high I/O count of 502 plus 4 dedicated inputs makes the device suitable for high-density bus bridges, telecom line cards, and parallel DSP datapaths. The architecture pairs a four-element LUT (LE) with an adjacent product-term (Macrocell) share, feeding a Logic Array Block (LAB) of ten LEs. Embedded Array Blocks (EABs) implement synchronous dual-port RAM up to 2,048 bits per block, totaling 212,992 RAM bits. Interconnect uses FastTrack continuous routing with predictable delay across the die, simplifying static timing closure. Typical applications include high-performance telecommunications line cards, parallel DSP co-processors, image-processing pipelines, bus-bridge ASIC prototyping, and industrial control designs where the APEX 20K family remains a long-lifecycle 5 V-tolerant I/O option. The V suffix denotes 2.5 V VCCINT operation; legacy 5 V designs can still use 3.3 V PCI-style I/O standards via banked VCCIO rails. When designing with this part, ensure banked VCCIO supplies match the I/O standard selected for each bank, and verify signal integrity at 167 MHz using IBIS models from the APEX 20K datasheet. Decoupling requires at least 12 x 0.1 µF plus 4 x 10 µF bulk capacitors placed around the BGA periphery. This page synthesizes the APEX 20K datasheet headline specs, distributor pricing, and drop-in alternatives within the EP20K400 family — engineering reference material not consolidated in any single distributor product page.

Within the broader semiconductor hierarchy, FPGAs sit above application-specific integrated circuits (ASICs) in flexibility but below them in per-unit cost and power efficiency. The APEX-20KC family pioneered system-on-a-programmable-chip (SOPC) integration by combining LUT logic, product-term logic, and embedded memory blocks on a single die, enabling designers to build complete digital systems including processors, peripherals, and glue logic on one chip. Key differentiating features of the EP20K400BI652-2 include its 652-ball BGA package measuring 45 x 45 mm, support for LVDS I/O at data rates suitable for backplane and high-speed serial interfaces, and compatibility with the Quartus development toolchain. The device includes on-chip phase-locked loops (PLLs) for clock management, embedded memory blocks for FIFO and dual-port RAM applications, and dedicated multiplier circuitry for DSP functions. Typical applications for the EP20K400BI652-2 include telecommunications infrastructure, industrial automation controllers, military and aerospace signal processing, and high-speed data acquisition systems. Its combination of high logic density, generous embedded memory, and LVDS support makes it well suited for designs that previously required multiple discrete FPGAs or a custom ASIC. When designing with this device, engineers should plan for the 1.71 V to 1.89 V core supply rail using a low-noise LDO regulator, and observe BGA fanout and routing rules to maintain signal integrity on the 652-ball land pattern. The device is shipped in tray packaging suitable for prototype and low-volume production builds.
