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

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

EP20K100QC240-3V

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

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

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

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

EP20K100QI240-2 - APEX 20K FPGA 100K Gates 240-PQFP | Intel

The Intel (Altera) EP20K100QI240-2 is an APEX 20K family Field Programmable Gate Array (FPGA) with 100,000 typical gates, 4,160 logic elements, 53,248 RAM bits, and 189 user I/Os, housed in a 240-pin Power Quad Flat Pack (PQFP / BFQFP) package. It is fabricated on a 0.22 µm CMOS process with a 2.5 V core supply and supports system clock speeds up to 200 MHz. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that engineers can re-program in the field to implement arbitrary digital logic, glue logic, DSP pipelines, or even full soft processors. FPGAs occupy the upper tier of the programmable logic hierarchy (FPGA > CPLD > SPLD > PAL/GAL) and are widely used for prototyping ASICs, low-volume custom compute, hardware-accelerated signal processing, and interface bridging. The APEX 20K family was notable for introducing MultiCore™ embedded system blocks, allowing on-chip integration of dual-port RAM, CAM, or ROM. Key features of the EP20K100QI240-2 include 4,160 logic elements, 53,248 RAM bits, 189 user I/Os, propagation delay of approximately 1.6 ns, a maximum internal frequency of 200 MHz, and 4 dedicated inputs plus 4 global clocks. The 2.5 V core (with 3.3 V PCI-compliant I/O tolerance on selected banks) and 0.22 µm CMOS process deliver industry-leading density for its generation. Architecturally, the device integrates Look-Up Table (LUT) logic, product-term logic, and embedded memory in a single MultiCore fabric - a hybrid scheme that lets the designer place register-intensive datapaths in LUTs while implementing fast control logic in product terms. This MultiCore approach, combined with True-LVDS and PLLs, made APEX 20K a popular choice for high-speed telecom and DSP backplanes in the late 1990s and early 2000s. Typical applications include digital signal processing (DSP) front-ends, telecom protocol bridging, custom peripheral controllers for embedded systems, image-processing pipelines, and industrial control glue logic. The 189 user I/Os make it suitable for wide parallel buses connecting microprocessors, memory, and analog front ends. When designing with the EP20K100QI240-2, engineers should note that this device is part of the mature APEX 20K family and is recommended only for legacy maintenance and existing design support; new designs should target Cyclone, Arria, or Stratix families. Quartus II design software (legacy versions) is required for place-and-route. This page synthesizes distributor pricing, drop-in same-package alternatives within the APEX 20K family, and practical design notes not consolidated in the manufacturer datasheet, giving engineers a single reference for sourcing and second-sourcing decisions.

EP20K100QI240-2N - 100K Gate APEX 20K FPGA | Altera

The Altera EP20K100QI240-2N is an APEX 20K family field-programmable gate array (FPGA) integrating approximately 100,000 system gates, 4,160 logic elements, and up to 53,248 RAM bits, with 200 MHz-class internal performance and a 2.5 V core, supplied in a 240-pin PQFP package. A field-programmable gate array (FPGA) is an integrated circuit whose logic fabric can be configured after manufacturing, placing it along the programmable logic device hierarchy of FPGA -> programmable logic device -> integrated circuit. The EP20K100 uses Altera's MultiCore architecture, which combines look-up table (LUT) logic, product-term logic, and embedded memory in a single device. That integration allows designers to implement register-intensive datapaths, wide combinational functions, and on-chip memory in one programmable component. Key verified features include the APEX 20K architecture, 4,160 logic elements, 100K system gates, 53,248 embedded RAM bits, 189 user I/Os, a 2.5 V nominal core supply, and a -2 speed grade. The -N suffix in this ordering code identifies the lead-free package variant used for RoHS-directed assembly. The PQFP-240 package has a 32 mm square body, 0.5 mm terminal pitch, and gull-wing terminals, allowing conventional fine-pitch surface-mount assembly. The device is manufactured on a 0.22 um CMOS process, with VCCINT specified at 2.5 V nominal and a verified operating range of 2.375 V to 2.625 V. According to distributor and datasheet data, the 240-pin package provides 189 user I/O and 4 dedicated inputs. This combination of logic density, memory bits, and package size makes the EP20K100QI240-2N suitable for moderate-complexity digital systems that need reprogrammable logic without migrating to a BGA package. Typical applications include communications line cards, industrial control boards, digital video equipment, and high-performance test instruments. The industrial temperature ordering option and lead-free finish make it attractive for rugged systems that must be assembled on lead-free production lines. The on-chip embedded memory reduces the need for external FIFO or SRAM components in many designs. When designing with this device, remember that the configuration SRAM is volatile. An external Altera configuration device such as EPC2 or EPC16, or a JTAG configuration host, is required to load the FPGA at power-up. Use adequate 0.1 uF and 1 uF decoupling capacitors near VCCINT pins and distribute the 2.5 V rail on a solid power plane to maintain reliable operation across the operating range. This page synthesizes verified distributor snippets, datasheet document references, same-family drop-in alternatives, and practical design guidance that is not repeated in the original APEX 20K datasheet, providing an information-gain resource for engineers evaluating obsolete APEX 20K inventory or replacement options.

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

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

EP20K100TC144-3 - APEX 20K 100K Gates FPGA 144TQFP | Intel

The Intel (Altera) EP20K100TC144-3 is a member of the APEX 20K programmable logic device family, delivering 100,000 typical gates and 4,160 logic elements in a 144-pin TQFP (Thin Quad Flat Pack) package. Built on a 0.22 µm CMOS process with 2.5 V core supply, this device is specified for a commercial operating temperature range of 0 °C to 85 °C and a maximum internal frequency around 167 MHz. The EP20K100TC144-3 provides 101 user I/O pins, MultiCore interconnect architecture, embedded system blocks (ESBs) for memory, and Look-Up Table (LUT)-based logic for high-integration designs. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be configured by the customer after manufacturing. FPGAs belong to the broader category of programmable logic devices (PLDs), which also includes CPLDs and SPLDs. Within the digital logic hierarchy, an FPGA sits above fixed-function ASICs in flexibility and below microprocessors in software programmability. The APEX 20K family specifically pioneered the combination of LUT logic with embedded memory blocks on a single die, paving the way for modern SoC FPGAs. Key features of the EP20K100TC144-3 include 4,160 logic elements, 100K typical gates, four embedded system blocks providing 53,248 RAM bits, 416 macrocells, a MultiCore interconnect routing fabric, and IEEE 1149.1 JTAG boundary-scan support. The device is in-system programmable via the IEEE 1532 / 1149.1 interface, allowing rapid prototyping and field upgrades. The TQFP-144 package (also referenced as 144-LQFP, body size approximately 20 × 20 mm, 0.5 mm pitch) provides 101 usable I/O lines with multiple I/O standards including LVTTL, LVCMOS, PCI, and SSTL. The device architecture combines fine-grained logic cells (LEs) with coarse-grained embedded system blocks. Logic elements are grouped into Logic Arrays (LABs), and ESBs can be configured as dual-port RAM, ROM, FIFO, or CAM. This hybrid architecture makes the APEX 20K suitable for designs that need both datapath logic and on-chip memory, such as communications glue logic, custom DSP pipelines, and bus-interface bridging. Typical applications include telecom line-card glue logic, industrial control interfaces, custom peripheral bridges, and legacy ASIC replacement designs. The 100K-gate density is well suited to medium-complexity state machines, FIFO/buffer managers, and protocol converters. Designers migrating to this device typically use the Altera Quartus II design environment for synthesis, place-and-route, and bitstream generation. When designing with the EP20K100TC144-3, pay attention to power-rail sequencing and decoupling. The 2.5 V core and 3.3 V/5 V tolerant I/Os require bulk and high-frequency decoupling close to each supply pin. Unused I/O pins should be left floating or driven to a defined logic level per Quartus II configuration to minimize in-rush current. Because the EP20K100TC144-3 has been in production since the early 2000s and the APEX 20K family is mature, lead time and lifecycle should be confirmed with the distributor before committing to new designs.

The device is part of an EOL product line and is targeted at industrial, telecom, and embedded computing applications where moderate logic density, on-chip RAM, and proven multi-vintage design support outweigh the need for the latest process node. The architecture employs LUT-based logic elements grouped into MegaLAB structures, with each MegaLAB containing 16 Logic Array Blocks and a single Embedded System Block providing up to 2 Kbits of dual-port RAM. Inter-MegaLAB routing is handled by a continuous FastTrack interconnect that supports both row and column paths, minimizing interconnect delay for high-fanout nets. Typical applications include telecommunications line cards, industrial control logic, legacy PCI bridge designs, peripheral controllers, and ASIC prototyping where a mature, well-documented device with decades of design support is preferred over newer families. The 144-LQFP package also enables hand-solderable prototypes and rework on standard 2-layer boards. When designing with the EP20K100TC144-3N, use the Quartus II design software (legacy versions 7.x–13.x) or MAX+PLUS II for older schematics, and verify all I/O assignments against the 144-pin TQFP pinout because several package variants exist within the same family. Note that this part is marked obsolete by Intel and is supplied primarily through authorized distributors of last resort - plan for end-of-life lifecycle management when using this device in new designs.

Key features include 51,840 logic elements, 216 Kb of embedded system block RAM, up to 488 user I/O pins supporting multiple I/O standards (LVTTL, LVCMOS, PCI, GTL+, HSTL, SSTL), and four phase-locked loops for clock management. The 652-BGA package supports high-pin-count designs while remaining suitable for high-volume SMT assembly, and the device is available in commercial (C), industrial, and military temperature grades. The APEX 20KC architecture combines a MultiCore architecture with embedded system blocks to deliver high throughput for datapath-intensive applications. ESBs can be configured as dual-port RAM, ROM, or first-in first-out (FIFO) buffers, eliminating external memory in many bus-interface and pipeline designs. True-LVDS and high-speed I/O support enables gigabit-rate serial links without external transceivers. Typical applications include telecommunications line cards, network routers, high-speed image-processing pipelines, DSP co-processing accelerators, and military/aerospace signal-processing subsystems. The APEX 20KC also serves legacy industrial-control backplanes where firmware updates must roll forward without hardware changes. When designing with the EP20K1500CB652C7ES, account for JTAG boundary-scan testing, MultiVolt I/O banking, and the Quartus II design-flow legacy.

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

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

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

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

The 'E' suffix indicates enhanced I/O standards and the 'C240' suffix indicates the 240-pin PQFP package with commercial 0 to 85 C temperature grading. The APEX 20KE architecture combines a fine-grained logic fabric with coarse-grained embedded system blocks, allowing the device to be configured as logic, memory, or a mixture of both. The four PLLs reduce clock skew and support frequency multiplication and division across multiple clock domains, while dedicated high-speed I/O structures allow data rates up to 622 Mbps on LVDS or GTL+ links. The device is fabricated on a 0.18-micron CMOS process with six-layer metal interconnect. Typical applications include telecommunications line cards, network switching fabrics, high-speed serial backplane interfaces, DSP preprocessing pipelines, and embedded control systems where deterministic hardware logic is required. The 622 Mbps LVDS capability also makes the EP20K160EQC240-2 suitable for SPI-4.2 (POS-PHY Level 4) and similar chip-to-chip interconnect standards. When designing with this device, ensure that the Quartus design tool (or MAX+PLUS II for legacy flows) supports the target APEX 20KE variant and that all I/O banks receive their reference voltages correctly for SSTL or GTL+ signalling. Configuration is typically performed via passive serial (PS), passive parallel synchronous (PPS), or JTAG programming using a serial configuration device such as the EPC2 or EPC16.

EP20K160EQC240-2X

EP20K160EQC240-2X - APEX 20KE FPGA 160K Gates 240-PQFP | Intel

The Intel (Altera) EP20K160EQC240-2X is a member of the APEX 20KE family of field programmable gate arrays, integrating 160,000 system gates with 6,400 logic elements in a 240-pin Power Quad Flat Pack (PQFP) package. The device is fabricated on a 0.22 um CMOS process and operates from a 1.8 V core supply with multi-voltage I/O support, delivering internal clock frequencies up to 350 MHz and propagation delays around 1.93 ns. What is a FPGA? A Field Programmable Gate Array is a type of programmable logic device (PLD) that allows designers to configure digital logic blocks and interconnect after manufacturing. FPGAs sit in the broader hierarchy of programmable logic devices: PLD -> CPLD -> FPGA -> SoC FPGA. They are widely used to implement custom digital signal processing, glue logic, bus interfaces, and high-speed parallel processing pipelines that would otherwise require discrete logic ICs or ASICs. The EP20K160EQC240-2X features the APEX MultiCore architecture combining look-up table (LUT)-based logic with embedded array blocks (EABs) for memory and arithmetic functions. It provides up to 271 user I/Os, 4 phase-locked loops, 345,600 bits of embedded memory, and supports in-system programmability via the IEEE 1149.1 JTAG interface. The -2 speed grade indicates a mid-tier performance classification within the APEX 20KE product line. Typical applications include telecommunications backplane interfacing, custom DSP pipelines, industrial control glue logic, and legacy system prototyping. The 240-pin PQFP package enables socketed or hand-soldered assembly, which is preferred for prototype boards and legacy through-hole-friendly designs where BGA rework capability is limited. When designing with this part, note that 1.8 V core and I/O voltages require level-shifters when interfacing to 3.3 V or 5 V logic families. The MultiCore architecture also requires Quartus II (or MAX+PLUS II for legacy flows) for place-and-route, and configuration bitstream generation from Verilog or VHDL source. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes not found in the original manufacturer datasheet. Engineers migrating designs from older Altera tools should review the Quartus II device support notes before recompiling existing APEX 20KE projects.

EP20K160EQC240-3

EP20K160EQC240-3 - APEX 20K 160K Gates FPGA | Intel / Altera

The Intel (formerly Altera) EP20K160EQC240-3 is a member of the APEX 20K family of FPGAs, integrating 160,000 typical gates (approximately 404,000 maximum system gates) with up to 640 macrocells and 175 user I/O pins in a 240-pin PowerQuad Flat Pack (QFP) package. It combines look-up table (LUT)-based logic, embedded system blocks (ESBs) for memory, and a MultiCore architecture for high-density programmable logic on a single die. The device operates from a 1.8 V core supply with multi-voltage I/O support. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that engineers configure after manufacturing to implement custom digital circuits. FPGAs sit hierarchically under programmable logic -> PLD -> digital IC -> semiconductor. The APEX 20K family was a landmark multi-vendor-compatible architecture (jointly defined by Altera and competitor devices in the same era) that merged gate-array density with on-chip memory, making it suitable for system-on-chip prototyping, glue logic, and DSP preprocessing blocks before modern System-on-Chip FPGAs took over. Key features of the EP20K160EQC240-3 include 640 macrocells / 4,160 logic elements, 160 K typical gates, 175 user I/O pins, embedded system blocks totaling approximately 53,248 RAM bits, and support for LVTTL, LVCMOS, SSTL, HSTL, and PCI I/O standards via dedicated I/O banks. The device is fabricated on a 0.18 µm CMOS process and supports in-system programmability through the IEEE 1149.1 JTAG interface plus a passive serial configuration port. Speed grade -3 indicates the slowest of the APEX 20K commercial speed grades; speed grade -1 and -2 variants offer faster timing closure at higher cost. The MultiCore architecture interleaves LUT logic with embedded array blocks, allowing designers to implement wide datapaths, FIFOs, and dual-port RAM without consuming general-purpose routing. The 240-pin QFP package provides gull-wing leads for surface-mount assembly, and the 175 available I/Os (versus 240 package pins) reflect the die-to-package I/O ratio typical of the APEX 20K EQC-series. Typical applications include telecommunications line cards, industrial control and factory automation, ASIC prototyping, glue logic replacement, embedded DSP preprocessing, image and video processing front-ends, and legacy system upgrades where designers port older gate-array designs onto a programmable platform. The 1.8 V core and 3.3 V/2.5 V I/O compatibility make it straightforward to bridge legacy 5 V tolerant buses through external resistors. The APEX 20K family is now in end-of-life status, so this part is mainly sourced through distributors stocking legacy inventory. Designers should note that APEX 20K is supported by the legacy Altera Quartus II design software (versions up to 13.0sp1). Modern Quartus does not support this device. When designing, ensure the JTAG chain configuration matches IEEE 1149.1 boundary-scan requirements and that the VCCIO of each bank is set correctly to match the connected bus voltage. Unused I/O pins should be left floating or driven per the Quartus II device handbook to avoid leakage during in-circuit testing.

EP20K160EQC240-3N

EP20K160EQC240-3N - APEX 20K 160K Gates 271 I/O FPGA | Intel

The Intel EP20K160EQC240-3N is a member of the APEX 20K family of programmable logic devices, delivering 160,000 system gates with 640 logic elements (6400 cells) in a 240-pin PQFP package. Operating at 1.8V core with 3.3V I/O, this FPGA features 271 user I/Os and a 323 MHz internal frequency based on the 0.22 µm CMOS MultiCore architecture. The "3N" speed grade corresponds to a 1.55 ns propagation delay, and the device operates across the commercial 0 °C to 85 °C temperature range. An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) containing configurable logic blocks, programmable interconnect, and I/O cells that engineers can customize after manufacturing. Within the broader semiconductor taxonomy, FPGAs sit under programmable logic -> logic ICs -> integrated circuits. The APEX 20K family specifically pioneered System-on-a-Programmable-Chip (SOPC) integration, combining look-up-table based logic with embedded memory blocks for high-density glue-logic and datapath applications. Key features include MultiCore architecture combining fine-grain logic with embedded array blocks (EABs) for memory and arithmetic, in-system programmability via IEEE 1149.1 JTAG, multi-voltage I/O supporting 1.8V/2.5V/3.3V interfaces, and LVTTL/LVCMOS/LVDS signaling. The device supports up to 87,040 RAM bits distributed across embedded array blocks, enabling single-chip implementation of FIFOs, dual-port RAM, and DSP-like datapath functions without external memory. The MultiCore architecture partitions each logic element into a carry-chain for arithmetic plus a register-rich LUT section, allowing efficient mapping of counters, state machines, and datapath pipelines. Built-in JTAG (IEEE 1149.1) boundary-scan and ISR (in-system reconfigurability) let engineers reprogram the device in-circuit, simplifying field upgrades and shortening prototyping cycles. The 0.22 µm CMOS process delivers the speed/power trade-off that made APEX 20K a workhorse for telecom line cards and ASIC prototyping in the early 2000s. Typical applications include ASIC prototyping, telecommunications line-card glue logic, networking datapath pipelines, and industrial control systems. Designers select this part when they need tens of thousands of gates with embedded block memory, JTAG-based in-system upgrades, and 240-pin PQFP board compatibility. When designing with the EP20K160EQC240-3N, plan for 1.8V core regulation with bulk decoupling near each VCCINT pin and 3.3V VCCIO rails matched to your logic interface. Use the Quartus II design environment for fitting; place series terminators on clock outputs to limit overshoot, and follow Altera's AN 117 application note for JTAG chain design.

EP20K160ETC144-2 FPGA - 160K Gate APEX 20KE | Altera
EP20K160ETC144-2

EP20K160ETC144-2 FPGA - 160K Gate APEX 20KE | Altera

The Altera EP20K160ETC144-2 is an APEX-20KE field-programmable gate array (FPGA) that provides 160,000 system gates, 6,400 logic elements, 81,920 RAM bits and 88 user I/O pins in a 144-pin LQFP/TQFP (20 x 20 mm) package. It is a 1.8 V core FPGA, speed grade -2, and belongs to the APEX 20KE family designed for system-level integration. An FPGA is an integrated circuit whose logic fabric can be programmed after manufacturing to implement arbitrary digital functions. APEX-20KE devices combine logic elements, embedded system blocks for memory and product-term functions, and programmable I/O in a hierarchical array, enabling designers to integrate board-level glue logic into one component. In the taxonomy of programmable logic, this device sits at FPGA > Programmable Logic Device > Integrated Circuit, and it is used where high reconfigurability and moderate pin count matter more than ASIC NRE. Key features of this part include 6,400 logic elements for moderate-density logic, 81,920 RAM bits for FIFOs and register files, 88 user I/Os, and a 1.71 V to 1.89 V supply range. Distribution literature lists a 0.22 um CMOS process and 350 MHz-class operation. The APEX-20KE embedded system blocks can implement memory or product-term logic, providing flexibility beyond plain FPGA logic. The speed grade -2 is slower than -1X but is commonly supported by legacy design files and reference implementations. Architecturally, EP20K160ETC144-2 builds logic from logic array blocks and embeds memory-oriented system blocks, connected by a hierarchical routing architecture. This lets the device realize 160K system gates without requiring an external RAM for every FIFO. The 20 x 20 mm TQFP package is surface-mount, compatible with 0.5 mm pitch PCB processes, and simpler to route than larger BGA alternatives. Because the part has no nonvolatile flash, it must be configured at power-up from an external EPC serial configuration device. Typical applications include wired-communications line-card glue logic, industrial PLC I/O conversion, test-and-measurement front ends, and legacy aerospace repair programs where the original APEX-20KE firmware must remain unchanged. Its 88 I/Os and embedded RAM make it adequate for 16-bit parallel buses, UART/SPI interfaces, encoder counters, and custom timing state machines. For designs requiring more I/O, move to a larger APEX-20KE package such as 208-pin or 240-pin, but note that package and pin assignments change. When using this component, pay attention to the 1.8 V core accuracy and the external configuration PROM. Because the EP20K160ETC144-2 is obsolete, check lifecycle and stock before starting a design; use the -2N lead-free variant when RoHS assembly is mandatory, and re-verify timing if selecting an X speed-bin alternative. This page synthesizes distributor pricing, package details, drop-in variants and practical notes that are not all present in a single manufacturer datasheet section. It is intended to help engineers sourcing the EP20K160ETC144-2 for repair, legacy extension, or aftermarket builds make faster, better-informed decisions.
