EP20K100CB356C8 - APEX-20K 100K-Gate FPGA, 356-BGA | Intel
The Intel (formerly Altera) EP20K100CB356C8 is a member of the APEX 20K family of high-density SRAM-based Field-Programmable Gate Arrays, integrating 100,000 typical gates in a 356-ball LBGA package. It is fabricated on a 0.18 µm CMOS process and combines look-up table (LUT) logic with embedded array blocks (EABs) that can each implement up to 2 Kbits of dual-port RAM, ROM, or first-in-first-out (FIFO) memory. The device also includes four phase-locked loops (PLLs) for clock management and supports multi-voltage I/O operation on a per-pin basis. A Field-Programmable Gate Array (FPGA) is a type of integrated circuit that can be reprogrammed after manufacture to implement arbitrary digital logic, occupying a position in the programmable-logic hierarchy between simple programmable logic devices (SPLDs/CPLDs) and application-specific integrated circuits (ASICs). Within Intel's programmable solutions portfolio, the APEX 20K family predates the Cyclone and Arria series, and is now classified as a mature legacy device. EP20K100CB356C8 occupies the lower-density tier of the APEX 20K lineup, while sharing the same Quartus development-tool ecosystem and the same embedded-memory philosophy used in subsequent families. Key features of the EP20K100CB356C8 include 4,160 logic elements, 12 EABs providing 24 Kbits of embedded memory, a maximum of 252 user I/O pins, and four PLLs with up to six clock outputs. The device supports LVTTL, LVCMOS, SSTL, and GTL+ I/O standards via MultiVolt I/O and operates from a core supply of 1.8 V. Configuration is supported through passive serial (PS), passive parallel synchronous (PPS), passive parallel asynchronous (PPA), and JTAG modes, and the device is in-system programmable via IEEE 1532. The 356-ball LBGA package exposes a large number of user I/O and high-speed clock pins while providing a controlled-impedance substrate for high-speed signals. The on-chip PLLs enable frequency synthesis, phase shifting, and clock-skew management, which is essential for synchronous designs with multiple clock domains. The 0.18 µm process and embedded array block architecture deliver a favourable logic-to-memory ratio for datapath-intensive designs such as DSP filters, FIFO buffers, and bus-interface bridges. Typical applications include telecommunications line cards, industrial automation controllers, ASIC prototyping, glue-logic and bus-bridging designs, and legacy upgrades of designs that were originally implemented on APEX 20K silicon. Designers migrating to a current Intel FPGA should consider Cyclone IV/V or MAX 10 as the recommended modern equivalents, depending on logic, memory, and I/O requirements. When designing with this device, note that the 1.8 V core supply is internally generated by an on-chip voltage regulator when the 2.5 V VCCINT is applied, but the PLL analog supply and the JTAG pull-up voltage still require dedicated rails. Ensure the JTAG chain is terminated correctly and that the configuration scheme matches the system boot timing, as the APEX 20K family uses a 16-bit-wide passive-parallel mode in addition to the more common serial modes.
EP20K100CB356C8ES - APEX 20K 100K Gates 356-BGA FPGA | Intel
The Intel (formerly Altera) EP20K100CB356C8ES is an APEX 20K family Field-Programmable Gate Array (FPGA) housed in a 356-ball Fine-Pitch Ball Grid Array (BGA) package. The device integrates 100,000 typical gates, 4,160 logic elements, and 252 user I/O pins, delivering a logic density that targets glue-logic replacement, bus bridging, and medium-complexity DSP glue in industrial and telecom designs. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), embedded memory blocks, and programmable interconnects that the designer can rewire after manufacture. APEX 20K sits within the broader taxonomy: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit -> semiconductor. The EP20K100C variant delivers moderate logic capacity with embedded array blocks (EABs) suitable for memory, ROM, and specialized arithmetic functions, while the broader APEX 20K family combines look-up-table (LUT) logic with EABs on a single die. Key features of the EP20K100CB356C8ES include 100K typical gates, 4,160 logic elements, 26 EABs providing approximately 53,248 RAM bits, 252 maximum user I/O, multi-standard I/O support including LVTTL, LVCMOS, PCI, and GTL+, and an 8 ns speed grade (suffix "8") with commercial operating temperature range (suffix "C"). The "ES" suffix denotes an Engineering Sample, intended for prototype evaluation and pre-production builds rather than volume manufacturing. Technically, the device uses a 0.18 µm CMOS SRAM process with 5-metal-layer routing, supports in-system programmability via the IEEE 1149.1 JTAG interface and the Altera ByteBlaster/USB-Blaster configuration schemes, and operates from a 2.5 V core / 3.3 V I/O supply. The architecture combines logic elements with embedded array blocks to implement wide datapath functions, FIFO buffers, and content-addressable memory. Typical applications include telecommunications line cards, industrial control glue logic, PCI bus bridges, and legacy design maintenance. The wide I/O count makes it suitable for memory controller hubs and backplane interface bridges. Compared with newer low-cost Cyclone or modern Agilex families, the APEX 20K series is now primarily a legacy/maintenance component. When designing with this device, account for the legacy 2.5 V core rail requirement and verify Quartus II support version compatibility - Quartus II 9.0 or earlier is the recommended toolchain. Engineering samples should not be used for production qualification; request the production-grade variant (without "ES") for volume builds. This page synthesizes distributor pricing, drop-in alternatives within the APEX 20K family, and practical design notes for legacy FPGA maintenance not found in the original datasheet alone.
EP20K100CB356C9 - 252-I/O APEX-20K FPGA | Intel | Embedded Logic
Intel EP20K100CB356C9 is a high-performance EPROM-based field-programmable gate array in the APEX-20K family, providing 252 user I/O connections and a 356-ball Ball Grid Array package. The verified data identifies the part as an FPGA with 252 I/O and a 356BGA package, supporting high-density embedded and programmable-logic designs. The device belongs to the APEX-20K architecture, an early programmable-logic family combining FPGA flexibility with structured embedded-system integration capabilities. An FPGA, or field-programmable gate array, is a semiconductor device whose logic function is configured after manufacturing. FPGAs occupy the programmable-logic branch of the integrated-circuit hierarchy, above fixed-function logic and below or alongside processors in configurable digital systems. Their architecture generally includes configurable logic blocks, programmable interconnects, and configurable I/O resources. The APEX-20K family extends that model toward embedded system-on-programmable-chip applications, where designers can implement interfaces, control logic, datapaths, and other digital functions in one configurable device. The verified specifications identify 252 user I/O pins and a 356-ball BGA package. A 356-ball package provides a high pin count for programmable I/O, power, configuration, and other device functions, while the BGA format supports dense surface-mount routing and controlled electrical connections. The part is also described as an embedded FPGA, making it relevant to systems that need hardware-level concurrency, deterministic logic, and post-manufacture functional configuration. Verified data does not provide logic-element count, memory capacity, operating voltage, speed grade, temperature range, or configuration details, so those parameters remain unstated rather than inferred from the family name. The APEX-20K architecture is associated with programmable logic and embedded applications. Engineers should preserve the original configuration flow, pin assignment, I/O electrical settings, clocking scheme, and printed-circuit-board escape strategy when designing a replacement. Although several APEX-20K-family part numbers appear in the site MPN list, the available substitute data does not establish that any candidate is pin-compatible and electrically interchangeable with the target. A replacement therefore requires manufacturer cross-reference verification, datasheet comparison, footprint review, and timing or functional-equivalence testing. Typical verified or implied use cases include embedded control systems, high-density digital interfaces, industrial electronics, and communications or computing equipment requiring programmable hardware. The 252-I/O capability is particularly useful when many external signals must be connected to configurable logic. Designers should not treat the I/O count as a substitute for required I/O standards, voltage levels, timing margins, or package-ball verification. For new designs, confirm the complete electrical and mechanical requirements before selecting EP20K100CB356C9. For legacy replacement programs, first verify the exact package, ball map, configuration interface, power requirements, and supported design tools. The verified web results show distributor availability and quote-based purchasing, but they do not provide a complete manufacturer datasheet or all electrical characteristics. This product data combines verified package, I/O, inventory, and distributor information with explicit markers for unavailable specifications. It also distinguishes observed source facts from engineering considerations, helping procurement, design, and maintenance teams avoid assuming compatibility from a family name or similar product description.
EP20K100CF144C7 - APEX-20K FPGA 100K LE 144-LQFP | Intel
The Intel EP20K100CF144C7 is a member of the APEX-20K Field Programmable Gate Array family, providing approximately 100,000 system gates with 4,160 logic elements (LEs) and 53,248 bits of embedded system memory (ESB) in a 144-pin LQFP package. The device features 93 user I/O pins and is built on a 0.18-micron CMOS SRAM process with in-system programmability via IEEE 1149.1 JTAG and passive serial configuration modes. This C7 speed grade part is qualified for commercial operating temperature range of 0C to +85C. An FPGA (Field Programmable Gate Array) is a type of programmable logic device that allows engineers to implement custom digital circuits after PCB fabrication. FPGAs sit within the programmable logic hierarchy: FPGA -> programmable logic -> digital IC -> semiconductor. Unlike fixed-function ASICs, FPGAs are reconfigured in-circuit using HDL design flows, making them ideal for prototyping, low-volume production, and designs requiring late-stage hardware changes. The APEX-20K family further extends this with embedded memory blocks and a MultiCore architecture supporting fine-grain logic, embedded array blocks, and high-speed I/O. Key features of the EP20K100CF144C7 include 4,160 logic elements organized as Logic Array Blocks (LABs), 53,248 RAM bits distributed across embedded system blocks, 93 user I/O pins supporting LVTTL, LVCMOS, PCI, SSTL, and GTL+ I/O standards, four phase-locked loops (PLLs) for clock management, and dual-purpose configuration pins. The 144-pin LQFP package measures 22x22 mm with a 0.5 mm lead pitch and is suitable for surface-mount assembly on standard FR4 PCB substrates. Architecture-wise, the APEX-20K device combines a fine-grain logic fabric for register-intensive functions with embedded array blocks (EABs) optimized for memory and arithmetic. The device supports true dual-port RAM, FIFO, and CAM implementations via dedicated memory structures. I/O banks are powered by VCCIO rails that can be set independently from the core VCCINT supply, allowing mixed-voltage interfacing. Typical applications for this FPGA include telecommunications line cards, industrial control logic, test and measurement front-ends, low-density glue logic replacement, and ASIC prototyping. Designers select the EP20K100CF144C7 when a low-to-moderate logic density device with embedded memory and a pin-compatible surface-mount package is required for commercial-temperature deployments. Legacy designs originally specified around the APEX-20K family continue to source this part for long-lifecycle field support. When designing with this FPGA, allocate sufficient PCB area for decoupling capacitors near every VCCINT and VCCIO pin, and follow Intel/Altera configuration guidelines for the MSEL pin strapping. The 144-pin LQFP package has moderate thermal performance; thermal management is rarely required at typical APEX-20K operating frequencies but should be verified with junction-temperature calculation in high-utilization designs.

EP20K100CF144C7ES - APEX-20K 100K Gate FPGA 93 I/O 144-LQFP | Intel
The Intel EP20K100CF144C7ES is a member of the APEX-20K family of Field Programmable Gate Arrays (FPGAs), integrating 100,000 typical gates with 4,160 logic elements and 53,248 bits of embedded memory in a 144-pin LQFP package. Housed in a 144-LQFP (20x20 mm) package with 93 user I/O pins, this device targets complex digital designs requiring high integration density and flexible I/O. An FPGA (Field Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, all of which can be reconfigured by the end user after manufacture. FPGAs sit in the broader taxonomy of programmable logic devices (PLDs), which includes CPLDs and SPLDs as smaller predecessors. Within Intel's (formerly Altera's) portfolio, APEX-20K belongs to the multi-core architecture family that preceded Stratix, combining Look-in Table (LUT) logic with embedded memory blocks called ESBs (Embedded System Blocks). Key features of the EP20K100CF144C7ES include 100K typical gates (equivalent to approximately 53K logic elements usable for design), 4,160 actual logic elements, 53,248 RAM bits distributed across embedded system blocks, four Delay-Locked Loops (DLLs) for clock management, and multi-level interconnect with 4 dedicated FastTrack lines. The device operates from a 1.8V core supply with 3.3V or 5V tolerant I/O via banked voltage references. The 'C7' speed grade places it in a commercial-temperature, mid-speed bin, while the 'ES' suffix indicates an engineering sample / special-order variant. The APEX-20K architecture combines fine-grained LUT logic with coarse-grained ESB memory, allowing designers to implement both random logic and memory-intensive functions such as FIFOs, CAMs, and dual-port RAMs in a single device. Four DLLs provide zero-delay clock buffering and frequency synthesis, simplifying timing closure in multi-clock-domain designs. The FastTrack interconnect offers predictable routing delays across the die, which shortens synthesis iterations in Quartus II and legacy MAX+PLUS II tool flows. Typical applications include telecom line-card glue logic, industrial control and protocol bridging, ASIC prototyping, image processing front-ends, and embedded DSP co-processing. The wide I/O count (93 pins) makes it suitable for parallel bus interfaces and high-pin-count ASIC replacement designs. When designing with this device, ensure Quartus II (or MAX+PLUS II for legacy flows) is used for synthesis and fitting. Verify that the chosen speed grade meets timing closure for the target clock frequency, and budget adequate thermal headroom because the LQFP package has a relatively high junction-to-ambient thermal resistance compared with BGA alternatives. This page synthesizes distributor pricing, engineering-sample availability, drop-in alternatives within the APEX-20K family, and practical design notes not found in a solitary datasheet PDF, providing engineers with a consolidated decision-support view.
EP20K100CF144C8 - APEX-20K 100K Gate FPGA | Intel | 144-LQFP
The Intel EP20K100CF144C8 is a member of the APEX-20K family of Field Programmable Gate Arrays (FPGAs), delivering 100,000 system gates, 4,160 logic elements, and 53,248 bits of embedded memory in a 144-pin LQFP (Low-profile Quad Flat Pack) package. The device integrates 93 user I/O pins and is fabricated on a 0.18-micron CMOS process with MultiCore architecture combining look-up tables (LUTs), embedded array blocks (EABs) for memory, and high-speed interconnect. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows designers to configure digital logic circuits after manufacturing. The APEX-20K family belongs to the broader hierarchy of programmable logic devices (PLDs), which also includes complex PLDs (CPLDs). Within Intel's portfolio, FPGAs are categorized under Programmable Logic Devices (PLDs) > FPGAs. APEX-20K devices pioneered the MultiCore architecture that combines fine-grained logic and coarse-grained memory, making them well suited for system-on-chip (SoC) prototyping, DSP functions, and high-speed data-path designs. Key features include 100K typical gates, 4,160 logic elements, 53,248 RAM bits distributed across embedded array blocks, 260 maximum I/O pins (part-specific to this device is 93 user I/Os in the 144-LQFP package), and a speed grade of -8 (commercial, mid-range). The device supports in-system programmability (ISP) via IEEE 1149.1 JTAG and offers 3.3V and 5.0V PCI compliance. The 144-LQFP package is a plastic surface-mount variant with 1.0 mm pitch and body size 20x20 mm, suitable for prototyping and low-to-medium volume production. The architecture combines four types of logic resources: logic array blocks (LABs) for combinatorial and sequential logic, embedded system blocks (ESBs) for dual-port RAM, ROM, and CAM functions, fast-track interconnect for high-speed routing between rows and columns, and a network of embedded array blocks (EABs) for memory-intensive operations. This heterogeneous structure enables efficient implementation of both logic-heavy and memory-heavy designs on a single device, eliminating the need for external memory in many applications. Typical applications include telecommunications equipment, industrial automation controllers, ASIC prototyping, high-speed digital signal processing (DSP), PCI bus interfaces, and embedded control systems. The 144-LQFP package and 93 user I/Os make it well suited for designs that need to bring out numerous signals for boundary-scan testing, external memory interfaces, or multi-channel I/O. When designing with this device, ensure your board layout provides adequate decoupling (100 nF high-frequency ceramic and bulk tantalum or aluminum electrolytic capacitors) near each supply pin. Use the JTAG interface for ISP programming to support field upgrades. Plan I/O assignments early because the 144-LQFP package limits the package-out versus ball-grid options of larger APEX-20K devices.

EP20K100CF144C8ES - APEX-20K 100k Gate FPGA 144-LQFP | Intel
The Intel (formerly Altera) EP20K100CF144C8ES is a 100,000-gate APEX-20K series Field Programmable Gate Array (FPGA) with 53,248 logic elements and 4,160 embedded RAM bits, housed in a 144-pin LQFP package. It provides 93 user I/O pins, operates from a 1.8V core supply with 3.3V/2.5V/1.8V multi-voltage I/O support, and is rated for the commercial 0C to +85C temperature range with an 8 ns pin-to-pin logic delay grade. What is an FPGA? An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that can be reconfigured by the designer after manufacture. FPGAs sit hierarchically under programmable logic devices (PLDs), which fall under digital integrated circuits, which are a subset of semiconductors. APEX-20K FPGAs specifically combine Look-Up Table (LUT)-based logic with embedded array blocks (EABs) that implement dual-port RAM, ROM, and multiplier functions, enabling a single chip to replace many discrete logic ICs. Key features of the EP20K100CF144C8ES include MultiVolt I/O supporting 1.8V, 2.5V, and 3.3V interfaces without external level shifters, four Phase-Locked Loops (PLLs) for clock multiplication and skew management, and 4160 RAM bits distributed across embedded array blocks. The 144-LQFP package offers 93 user I/O pins at 0.5 mm pitch, which is the highest I/O count available for the EP20K100 device density. The architecture combines a Logic Array Block (LAB) fabric of 4160 LUTs with Embedded Array Blocks (EABs) that can each implement 2 Kbits of dual-port RAM or ROM. The four on-chip PLLs generate up to four independent clock domains from a single reference, supporting frequency synthesis up to the device maximum. Boundary-scan (IEEE 1149.1 JTAG) is integrated for board-level test access, and the device is configured via passive serial, passive parallel, or in-system programmability through the IEEE 1532 standard. Typical applications include telecommunications line-card glue logic, industrial control system interfaces, ASIC prototyping and validation, low-to-medium volume production replacement of gate arrays, and PCI/PCI-X bus interfaces. The MultiVolt I/O and abundant user I/Os make it well suited for bridging legacy 5V-tolerant busses to modern 3.3V or 1.8V processors. When designing with this device, ensure the Quartus II design tool (or Max+Plus II for legacy flows) supports the -8 speed grade. The 144-LQFP requires standard JEDEC surface-mount reflow profiles; thermal performance is typically adequate without a heatsink for designs using fewer than 60% of available logic elements at moderate toggle rates.

EP20K100CF144C9 - APEX-20K FPGA 100K Gates 144-LQFP | Intel
The Intel EP20K100CF144C9 is a member of the APEX-20K family of field-programmable gate arrays (FPGAs) that combines look-up table (LUT) logic, embedded system blocks (ESBs), and a high-bandwidth interconnect fabric in a single device. It integrates approximately 100,000 typical gates and 4,160 logic elements in a 144-pin LQFP (Low-profile Quad Flat Pack) package, with 93 user I/O pins for interfacing to external memory, buses, and peripherals. An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) category in the broader semiconductor taxonomy: FPGA -> programmable logic device -> logic IC -> integrated circuit. Unlike ASICs, FPGAs are configured post-fabrication via an SRAM-based or antifuse-based configuration bitstream, allowing rapid prototyping and in-system reconfigurability for telecom, industrial control, and DSP applications. Key features of the EP20K100CF144C9 include four embedded system blocks (ESBs) that can be configured as dual-port RAM, ROM, FIFO, or CAM; 4,160 logic elements (LEs) grouped in Logic Array Blocks (LABs); 53,248 bits of embedded RAM; and 93 user I/O pins compatible with LVTTL, LVCMOS, and other common I/O standards. The device supports in-system programmability (ISP) via the IEEE 1149.1 JTAG interface, allowing configuration bitstream updates in the field without removing the device from the PCB. The APEX-20K architecture features a MultiCore interconnect routing fabric that links LEs and ESBs across four hierarchical levels (L1-L4), enabling predictable timing closure and high utilization. The die operates from a 2.5 V core supply and supports multi-voltage I/O via separate VCCIO banks. Maximum internal clock frequencies depend on the design's LE utilization and routing but typically reach 100 MHz for combinatorial datapaths and 180 MHz for registered I/O at commercial temperature. Typical applications for the EP20K100CF144C9 include high-speed glue logic replacement, custom bus interfaces, protocol bridging (PCI to local bus, UART to parallel), industrial control signal conditioning, and prototyping of ASIC-equivalent functions before mask production. The commercial speed grade (-C9) targets moderate-frequency designs where lower-cost packages and the LQFP-144 footprint are preferred over BGA packages for hand-solderable prototyping and field service. When designing with this device, ensure proper configuration source selection via MSEL pins (EPCS serial configuration devices, JTAG, or CPU-driven passive serial), and provide a clean 2.5 V core rail with adequate decoupling (typically 0.1 µF + 10 µF bulk) near each VCC pin pair. The 144-LQFP package has a 1.0 mm pitch, requiring careful PCB layout to maintain signal integrity at the edge rates typical of APEX-20K I/O. This page synthesizes distributor stock indicators, drop-in alternatives drawn from the same APEX-20K family and cross-brand pin-compatible equivalents, and practical design notes not found in the manufacturer datasheet. Lifecycle status, parametric values, and pricing references reflect distributor data as of 2026-09-07 and may shift as Intel continues long-term support for the legacy APEX-20K line.
EP20K100CF324C7 - 100K Gate FLEX 10K FPGA, 246 I/O, 324-FBGA | Intel
The Intel EP20K100CF324C7 is a high-density FLEX 10K family FPGA delivering 100,000 system gates, 4,160 logic elements (LEs), and 246 user I/O pins in a 324-ball FineLine BGA (FBGA) package. Built on a 0.22 µm CMOS SRAM process with embedded array blocks (EABs) for on-chip RAM and ROM, the device combines fine-grained logic with coarse-grained memory to optimize cost-effective data-path and control-logic designs. It operates from a 1.8 V core / 3.3 V I/O supply (multi-voltage I/O interface) and is specified for the commercial 0 °C to +70 °C temperature range, indicated by the C7 speed grade ordering code. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the user defines after manufacture via a configuration bitstream. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs) and, together with CPLDs, form the principal alternative to ASICs and microcontrollers for medium-volume, high-flexibility digital designs. Within Intel/Altera's portfolio, the FLEX 10K family is positioned as the second-generation embedded-array family, bridging classic gate-array architectures and modern system-on-chip FPGAs. Key features of the EP20K100CF324C7 include 4,160 LUTs / LEs, 12 EABs providing up to 49,152 RAM bits, 246 maximum user I/O pins, multi-voltage I/O supporting 1.5 V, 1.8 V, 2.5 V, and 3.3 V standards, and JTAG-based in-system programmability via the IEEE 1149.1 boundary-scan interface. The device is configured through a serial PROM or in-system via MAX+PLUS II / Quartus tools. The C7 speed grade is the slowest commercial bin, favored for power-sensitive designs that can tolerate lower clock rates. Architecturally, each LE contains a 4-input LUT, a programmable register, carry-chain logic, and a cascade-chain, while each EAB provides 2,048 RAM bits configurable as 256×8, 512×4, 1024×2, or 2048×1 with registered output. FastTrack interconnect provides row/column routing with predictable delays, and the embedded multiplier-free DSP blocks make the FLEX 10K suitable for glue logic, peripheral bridging, and small DSP pipelines. Typical applications include telecom line-card glue logic, industrial control backplanes, PCI/PCI-X bridge interfaces, video-format conversion, and ASIC prototyping. The 246 I/O count supports wide parallel buses, while the 49-Kbit embedded RAM enables FIFOs and small lookup tables without external memory. When designing with this device, note that the FLEX 10K is an older generation requiring MAX+PLUS II (legacy) or Quartus II 13.0 for bitstream generation; modern Quartus Prime releases do not support this device family. Plan configuration memory (EPC2/EPC4/EPC8 serial PROM) and confirm that 3.3 V I/O banks match your peripheral voltage to avoid level-shifter overhead.

EP20K100CF324C7ES - 100K APEX-20K FPGA 4160 LEs 246 I/O | Intel
The Intel (formerly Altera) EP20K100CF324C7ES is a member of the APEX-20K programmable logic device family, integrating 263,000 system gates and 4,160 logic elements (LEs) in a 324-ball FineLine BGA package. It features 246 user I/O pins, 53,248 total RAM bits, and operates from a 2.375V to 2.625V core supply using Intel's advanced 0.22 micrometer CMOS process with embedded memory and MultiCore interconnect. The device belongs to the C7 speed grade family, optimized for low-power commercial-temperature designs. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement arbitrary digital logic. FPGAs sit within the programmable logic taxonomy: CPLD < FPGA (small, low-density, non-volatile) → FPGA (volatile SRAM-based, high-density, rich I/O) → SoC FPGA (integrated hard-core processors). The APEX-20K family sits at the high-density, embedded-memory-rich end of this hierarchy and was one of the first families to combine look-up table (LUT) logic with embedded system blocks (ESBs) that double as dual-port RAM, ROM, or content-addressable memory. This hypernym chain — FPGA → programmable logic → programmable logic device (PLD) → digital ASIC alternative — helps map the part to the broader silicon taxonomy. Key features include 16 embedded system blocks (ESBs) for distributed memory, four phase-locked loops (PLLs) for clock management, and support for LVTTL, LVCMOS, PCI, SSTL, and GTL+ I/O standards. The FineLine BGA-324 (19x19 mm) package supports high-density board layouts while exposing 246 I/O for high-bandwidth interfaces. The C7 speed grade is the slowest in the APEX-20K family, prioritizing low quiescent current and cost over raw clock frequency. The device uses a LUT-based logic fabric with embedded array blocks (EABs/ESBs) providing distributed synchronous RAM. Its MultiCore architecture connects the logic array, memory, and I/O elements via a continuous, predictable routing structure that simplifies timing closure. The 2.5V core, 5V-tolerant I/O cells, and dedicated clock networks let the part serve as a glue-less interface between microprocessors, memory buses, and high-speed parallel peripherals in mid-density systems. Typical applications include PCI bus bridges, custom peripheral controllers for industrial backplanes, telecom line-card glue logic, and DSP co-processing front-ends. The device is also commonly seen in legacy POS terminals, printers, and high-channel-count data acquisition front-ends where 246 I/O are valuable and a soft-core CPU can be synthesized in fabric. When designing with this part, verify I/O bank voltage compatibility before assigning mixed-voltage signals to the same bank. The SRAM-based configuration requires a configuration device (EPC) or microprocessor boot stream at every power-up, since in-design state is volatile. Long lead times are common because the APEX-20K family is now in obsolescence planning — order quantities, lifecycle status, and last-time-buy dates should be confirmed with the supply chain before committing to a new design.
EP20K100CF324C8 - APEX-20K FPGA 100K Gates 324-BGA | Intel
The Intel (formerly Altera) EP20K100CF324C8 is an APEX-20K family Field-Programmable Gate Array (FPGA) integrating 100,000 typical gates, 4,160 logic elements, and 53,248 RAM bits, housed in a 324-ball FineLine BGA package. It offers 246 maximum user I/O pins and operates at a core voltage of 1.8 V typical, fabricated on a 0.18 µm CMOS process. The 'C8' speed grade places it in the commercial temperature range with an 8-pin speed delay specification, suitable for cost-sensitive, moderate-performance designs. What is a FPGA? A Field-Programmable Gate Array is a reconfigurable semiconductor device that contains an array of programmable logic blocks, interconnects, and I/O cells, all controlled by on-chip SRAM configuration memory. FPGAs sit in the programmable logic hierarchy between ASICs (custom-designed, high-NRE) and CPLDs (smaller, non-volatile), enabling rapid prototyping and mid-volume production without mask charges. The APEX-20K family introduced embedded memory blocks (ESBs) and a MultiCore architecture combining look-up tables, product-term logic, and dual-port RAM in a single fabric. Key features of the EP20K100CF324C8 include 4,160 logic elements (LEs), 26 embedded system blocks (ESBs) totaling 53,248 RAM bits, support for LVCMOS, LVTTL, SSTL, and HSTL I/O standards, and in-system programmability via the IEEE 1149.1 JTAG interface. The 324-FBGA package provides a 1.0 mm ball pitch, balancing board density and manufacturability for mainstream designs. The device also supports Altera's Quartus II design software (legacy versions recommended for this older family), with bitstream configuration via serial or parallel modes. Architecture-wise, the APEX-20K combines a Logic Array Block (LAB) fabric with embedded memory and PLLs, allowing designers to implement glue logic, state machines, FIFO buffers, and simple DSP functions in a single chip. The 100K-gate density targets applications like telecom interface cards, industrial control bridges, and protocol converters where ASIC NRE is unjustified but discrete logic is too bulky. Typical applications include telecommunications line cards, industrial automation controllers, networking bridges, PCI interface glue logic, and legacy system upgrades that require drop-in replacement of older Altera APEX designs. The wide I/O count (246) supports many parallel bus interfaces simultaneously. When designing with the EP20K100CF324C8, verify Quartus II legacy support before committing to the device, since this family predates modern Intel Quartus Prime releases. Plan for 1.8 V core supply decoupling and configure I/O banks to match the 3.3 V or 2.5 V logic levels of surrounding components. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical legacy-design notes not found in the original manufacturer datasheet.
EP20K100CF324C8ES - APEX 20K FPGA, 100K Gates, 324-FBGA | Intel
The Intel (formerly Altera) EP20K100CF324C8ES is a member of the APEX 20K family of FPGAs, integrating 100,000 typical gates (263,000 maximum system gates) into a 324-ball FineLine BGA package. It combines a Look-Up Table (LUT) fabric with embedded array blocks (EABs) for high-density logic and on-chip memory, supporting up to 4,160 logic elements and 246 user I/O pins. The 'C8' speed grade is optimized for commercial-temperature operation while the 'ES' suffix indicates an engineering sample. An FPGA (Field-Programmable Gate Array) is a reconfigurable semiconductor that belongs to the broader category of programmable logic devices (PLDs) within the integrated circuit (IC) taxonomy: FPGA -> PLD -> logic IC -> integrated circuit. APEX 20K devices were among the first to merge LUT-based logic with embedded memory blocks (EABs), allowing designers to implement wide datapaths, FIFOs, and multiplier functions without external SRAM. Key features of the EP20K100CF324C8ES include 4,160 logic elements, 26 EABs providing up to 53,248 RAM bits, 246 maximum user I/O pins, and multi-voltage I/O support (1.8 V, 2.5 V, 3.3 V, 5.0 V) through dedicated bank reference pins. It uses SRAM-based configuration loaded from a serial PROM or via JTAG, and integrates four Phase-Locked Loops (PLLs) for clock multiplication, division, and phase shifting across the device. Architecturally, the APEX 20K family employs a MultiCore architecture that ties MegaLAB structures together via a FastTrack continuous routing network. This delivers high predictable performance for synchronous designs, with tpd (pin-to-pin) and fmax figures characteristic of the C8 speed grade suitable for 80–100 MHz internal operation in typical datapath applications. Typical applications include telecommunications line cards, glue-logic replacement, high-speed DSP co-processing, industrial control and instrumentation backplanes, and legacy design maintenance for products shipped in the late 1990s and early 2000s. The large 246-I/O count makes the 324-FBGA package appropriate for parallel bus bridging applications. When designing with this device, ensure your configuration scheme (EPC16/EPC8 serial PROM or JTAG) matches the board layout. Because the APEX 20K family is mature and approaching end-of-life, confirm long-term availability before starting new production designs; consider Cyclone or MAX series for new projects. This page consolidates distributor pricing, same-brand drop-in alternatives within the EP20K100 family, and practical design notes that go beyond the manufacturer's datasheet summary, including cross-brand note that no third-party drop-in exists in the same 324-FBGA footprint.

The Intel EP20K100CF324C9 is a member of the APEX II family of SRAM-based FPGAs, integrating 100,000 typical gates (logic elements) with 246 user I/O pins in a 324-ball FineLine BGA package. The device combines look-up table (LUT)-based logic with embedded system blocks, enabling designers to implement complex glue logic, on-chip bus interfaces, and DSP-style datapaths on a single programmable device. Speed grade -9 (C9) places this variant in the higher-performance bin within the APEX II family. A field programmable gate array (FPGA) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement arbitrary digital logic. The APEX II architecture extends the FPGA concept by combining fine-grained logic elements with dedicated embedded system blocks (ESBs) for memory and arithmetic functions, occupying a position in the hierarchy between raw gate arrays and structured ASICs. Compared to mask-programmed gate arrays, FPGAs offer zero NRE cost and instant prototyping, at the expense of die area, static power, and per-unit cost. Key features of the EP20K100CF324C9 include 100,000 typical gates, 4,160 logic elements, and 246 maximum user I/O pins. The LUT-based logic fabric is paired with embedded array blocks, allowing distributed and block RAM functions alongside general-purpose logic. The device supports in-system configuration via the IEEE 1149.1 JTAG interface and supports Altera (now Intel) Quartus development flows for synthesis, place-and-route, and timing closure. The FineLine BGA-324 package supports high I/O density for parallel buses and memory interfaces. The architecture combines a MultiCore interconnect with row-and-column-based logic and embedded array blocks. Each logic element contains a 4-input LUT, a programmable register, and dedicated carry-chain logic for fast arithmetic. The embedded system blocks can be configured as dual-port RAM, ROM, or content-addressable memory, enabling efficient implementation of FIFOs, lookup tables, and small state machines directly in silicon without consuming general logic. Typical applications for the EP20K100CF324C9 include telecommunications line cards, networking switches and routers, industrial control and instrumentation, prototyping bridges between microprocessors and ASICs, and legacy designs that were originally migrated from the APEX 20K family into the APEX II family. The device is also widely used in telecommunications equipment where the 246 I/O count and embedded memory blocks simplify glue-logic and protocol-processing tasks. When designing with this device, plan for the 1.8 V core and 3.3 V/2.5 V I/O supply rails and ensure PCB layout supports the FineLine BGA escape. Verify timing closure in Quartus at the chosen speed grade -9 before committing to layout, and budget for configuration PROM or JTAG-based in-system programming. Static power and thermal dissipation are modest but should still be modeled in dense designs.

An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, allowing hardware designers to implement custom digital circuits after manufacturing. FPGAs sit within the broader hierarchy of programmable logic devices -> logic ICs -> integrated circuits -> semiconductors. The APEX20K family pioneered the multi-core architecture (Logic Array Blocks + Embedded System Blocks) that later Stratix and Cyclone families refined. Architecturally, the EP20K100CQ208C7 combines four Logic Array Blocks (LABs) interconnected via the FastTrack Interconnect routing fabric, with embedded system blocks providing True Dual-Port RAM and Content-Addressable Memory (CAM) support. The 1.8V core reduces dynamic power consumption compared to the older 5V FLEX10K family, while the LVTTL/LVCMOS I/O standards enable direct interfacing with modern microprocessors, DSPs, and memory devices without external level shifters. Typical applications include legacy telecommunications backplane glue logic, industrial control systems, PCI bus interface bridges, and ASIC prototyping. The 159 user I/O pins comfortably support 32-bit processor bus emulation and multi-channel DMA controllers in cost-sensitive embedded designs. When designing with the EP20K100CQ208C7, ensure the Quartus II design tool (or MAX+PLUS II for legacy flows) is configured for the APEX20K device family and the 208-pin QFP package. The PQFP package's long lead frame requires careful signal integrity analysis for high-speed signals above 66 MHz.
EP20K100CQ208C7ES - 100K Gate APEX-20KE FPGA, 208-PQFP | Intel
The Intel EP20K100CQ208C7ES is a 100,000-gate APEX-20KE Field Programmable Gate Array (FPGA) housed in a 208-pin Power Quad Flat Pack (PQFP / BFQFP) package.

They bridge the gap between simpler CPLDs and high-end Stratix-class FPGAs, supporting both glue-logic replacement and moderate DSP/data-path workloads. Key features include 208 user I/O pins, 4 PLLs for clock management, multi-voltage I/O support (1.8V, 2.5V, 3.3V, 5.0V), 3.3V PCI-compliant operation, and JTAG-based in-system programmability via ByteBlaster or Master/Slave serial modes. The C8 speed grade specifies a 1.5ns pin-to-pin delay on standard I/O. The APEX 20KE architecture separates logic, memory, and interconnect into independent MultiCore domains, allowing concurrent operation of up to four system blocks per LAB cluster. Typical applications include telecommunications line cards, industrial control backplanes, PCI bridge designs, and legacy system upgrades for designs originally prototyped on APEX 20K devices. Designers transitioning to the -KE variant gain additional ESB memory and lower static power compared with the APEX 20K baseline. When designing with the EP20K100CQ208C8, observe the 1.25W typical power dissipation at full utilization and provide a minimum of 200 LFM airflow for sustained operation above 70% utilization. The PQFP-208 package requires an exposed-pad-style thermal footprint strategy; copper pours should extend at least 1 square inch beneath the package for adequate heat spreading.

EP20K100CQ208C8ES - APEX 20K FPGA 4160 LE | Intel
The Intel EP20K100CQ208C8ES is an APEX 20K family field-programmable gate array (FPGA) containing 4160 logic elements and up to 159 user I/O pins in a 208-pin QFP (BFQFP) package. The ordering code identifies a CQ208 variant of the EP20K100 device, supplied in tray packaging with an MSL rating of 3 (168 hours). As of 2026-09-07, this device is in the obsolete APEX 20K family and should only be designed into legacy or revision-controlled boards. An FPGA is a reconfigurable integrated circuit containing programmable logic fabric, programmable interconnect, and configurable I/O blocks. Unlike a fixed-function ASIC or MCU, an FPGA can implement many different digital logic functions by loading a configuration bitstream at power-up. An APEX 20K FPGA sits above simple CPLDs in capacity and is often used for protocol bridging, digital signal preprocessing, and bus interface aggregation. In a system hierarchy, an FPGA is one type of programmable logic device, often accompanied by configuration memory such as EPC2 or EPCS devices. The data captured for EP20K100CQ208C8ES confirms 4160 logic elements and 159 user I/O lines. The 208-pin QFP package provides a surface-mount footprint suitable for dense board layouts where ball grid arrays are not preferred. The package is available in tray format, and the MSL 3 rating means devices require baking if exposed to humidity before reflow. These facts make the part usable for legacy board repair, replacement inventories, and maintenance of existing APEX 20K systems. The APEX 20K architecture combines lookup-table-based logic elements with embedded memory-oriented blocks. For this specific ordering code, the maximum system gates, embedded RAM bits, core voltage, speed grade, and temperature grade are not explicitly stated in the captured web data. Engineers should verify those parameters from the Altera/Intel APEX 20K family datasheet before using the device in a timing-sensitive or supply-rail-sensitive design. Typical legacy applications include telecom line cards, Ethernet interface bridging, industrial controller backplanes, and high-channel-count test equipment. The 159 I/O pins provide enough connectivity for a wide parallel bus, address decoding, or an external memory interface, while the 4160 logic elements implement medium-density glue logic, state machines, and DSP supervision logic. The most important design consideration is lifecycle: Intel has classified the APEX 20K series as obsolete and recommends Cyclone IV family devices for new designs. Cyclone IV is not pin-compatible with the QFP208 footprint and requires board migration. For existing EP20K100CQ208C8ES boards, the practical action is to qualify a same-family QFP208 spare such as EP20K100CQ208C8 or EP20K100CQ208C7ES. This page synthesizes distributor availability, package data, ordering-code variants, lifecycle guidance, and design caveats that are not all included in the manufacturer datasheet, helping engineers make faster sourcing and obsolescence decisions.

EP20K100CQ240C8ES - 189-I/O 240QFP FPGA | Intel
The Altera/Intel EP20K100CQ240C8ES is a field-programmable gate array (FPGA) from Intel's programmable-solutions portfolio, listed with 4,160 logic elements/cells, 189 user I/O pins, 53,248 bits of on-chip RAM, and a 240-pin BFQFP package. As of 2026-09-07, distributor Heisener shows 4,816 pieces in stock; the public listing quotes “Request a Quote” rather than a fixed unit price. An FPGA is a reconfigurable digital integrated circuit built from programmable logic blocks, embedded memory, and programmable I/O pins that users configure after manufacturing using an HDL bitstream. In the semiconductor hierarchy, an FPGA belongs to programmable logic devices, then digital integrated circuits, then integrated circuits. Unlike fixed-function ASICs, FPGAs can be reconfigured during board development or field deployment, making them useful for low-to-mid-volume digital systems where logic changes are expected. Key features visible from the verified distributor data are the 4,160 logic elements/cells, 189 user I/O pins, and 53,248 bits of embedded RAM. The part is packaged in a 240-lead BFQFP, sometimes written as 240-QFP or 240-BQFP, and is offered in tray packaging. This amount of logic and I/O supports moderate digital designs such as bus interfaces, protocol converters, and parallel-data control logic without requiring an ASIC startup. Technically, the EP20K100CQ240C8ES appears to be an EP20K-series Intel/Altera FPGA. Some distributor pages associate the EP20K100 series with the FLEX 10KE family, but engineers should confirm exact architectural details in Intel device literature because the EP20K prefix is also associated with APEX 20K devices. The trailing “ES” suffix generally denotes an engineering-sample ordering option, while “C8” is part of the ordering-grade string; Intel should be asked to confirm qualification status and timing for the suffix used. Typical applications include parallel bus bridging, video or image-sensor interface logic, industrial control I/O expansion, telecom line-card status handling, ASIC prototyping, and low-cost FPGA evaluation boards. The 189 user I/O pins give designers enough connectivity for multiple 8-bit or 16-bit buses, control signals, and test headers in one device. When designing this FPGA into a board, verify the core and I/O voltage requirements, configuration-device plan, and speed grade before layout because the scraped distributor snippets do not include a complete electrical specification table. The 240-pin QFP footprint also requires careful fanout and decoupling near every supply pin. This page synthesizes current distributor stock signals, quote-based pricing context, same-package family alternatives, and practical design notes that are not all present in a single datasheet snippet, giving engineers a faster starting point for sourcing and validation decisions.
EP20K100CQ240C9 - APEX 20K FPGA 100K Gates 189 I/O QFP240 | Intel
The Intel EP20K100CQ240C9 is a member of the APEX 20K family of high-density SRAM-based FPGAs, integrating 100,000 typical gates, 4,160 logic elements, and 53,248 RAM bits in a 240-pin BQFP (QFP-240) package with 189 user I/O pins. It operates across a commercial temperature range and is built on a 0.22 µm CMOS SRAM process with in-system programmability via Intel (formerly Altera) Quartus and MAX+PLUS II design software. An FPGA (Field Programmable Gate Array) is a programmable logic device that allows engineers to implement custom digital circuits through configurable logic blocks (LABs), embedded memory arrays (ESBs), and programmable interconnect. Within the broader semiconductor taxonomy, FPGAs sit alongside ASICs, CPLDs, and microcontrollers as reconfigurable compute elements. The APEX 20K series was Intel/Altera's first device family to combine logic, memory, and dedicated I/O on a single die, enabling system-on-chip designs without external glue logic. Key features include 100,000 typical gates, 4,160 logic elements distributed across multiple Logic Array Blocks, 53,248 bits of embedded SRAM, 189 user I/O pins, and 4 Phase-Locked Loops (PLLs) for clock management. The device supports multiple I/O standards including LVTTL, LVCMOS, PCI, and GTL, with per-pin output enable and programmable slew rate. The C9 speed grade denotes a -9 commercial-grade timing class, balancing logic density with timing closure for moderate-speed designs. Architecture-wise, the APEX 20K combines Look-Up Table (LUT)-based logic elements with Embedded System Blocks (ESBs) that can be configured as either dual-port RAM, ROM, or CAM. Four PLLs provide on-chip clock multiplication, division, phase shifting, and skew compensation. MultiCore voltage islands and JTAG boundary-scan (IEEE 1149.1) support simplify board-level testing. Typical applications include telecommunications infrastructure, industrial control, ASIC prototyping, glue logic replacement, and high-speed data-path designs. The 189 I/O count supports parallel bus architectures common in DSP front-ends and protocol bridges. Design consideration: route all clock signals through dedicated PLL outputs to minimize skew, and consult the APEX 20K handbook for I/O standard bank restrictions. Designers migrating to modern Intel/Altera FPGAs should note the APEX 20K is in legacy/last-time-buy status. This page synthesizes distributor stock data, parametric alternatives, and design considerations not found in the original manufacturer datasheet to assist procurement engineers evaluating the EP20K100CQ240C9 for new designs or legacy system maintenance.
EP20K100CT144C7 - APEX-20K FPGA, 100K Gates, 144-TQFP | Intel
The Intel (formerly Altera) EP20K100CT144C7 is a member of the APEX-20K family of Field Programmable Gate Arrays, delivering 100,000 typical gates and 4,160 logic elements in a 144-pin TQFP package. The device integrates Look-Up Table (LUT)-based logic, Embedded System Block (ESB) memory, and high-speed I/O on a single die, supporting up to 93 user I/O pins and offering 53,248 flip-flops for sequential logic density. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose digital logic function is defined by the user after manufacturing. Within the broader programmable logic hierarchy, an FPGA sits above CPLDs in both logic density and I/O capability and below ASICs in unit cost but far above in design flexibility. The APEX-20K family specifically introduced ESB blocks that can be configured as RAM, ROM, CAM, or product-term logic, allowing system-on-chip integration in a single device. Key features of the EP20K100CT144C7 include 100K typical gates, 53,248 system gates, 4,160 logic elements, 53248 flip-flops, 53248 maximum memory bits, and 93 user I/O pins. The device operates from a 1.8V core supply with 3.3V multi-voltage I/O support, and is fabricated on a 0.18-micrometer CMOS process. The commercial speed grade C7 places it at the slower-but-cost-optimized end of the APEX-20K speed spectrum. Architecturally, the EP20K100CT144C7 combines MegaWizard-style MegaLAB structures (groups of 16 Logic Elements) with Embedded System Blocks distributed in a columnar arrangement, allowing deterministic timing and efficient memory implementation. The 144-pin TQFP package exposes 93 user I/O pins while consuming 31.4 mm of board area per side - acceptable for legacy designs but no longer recommended for new high-density layouts. Typical applications include telecommunications infrastructure, industrial control, ASIC prototyping, glue-logic consolidation, and DSP preprocessing. Engineers also use APEX-20K devices for PCI bus bridging, custom peripheral controllers, and gate-array prototyping where NRE cost is prohibitive. When designing with this device, ensure Quartus or MAX+PLUS II support is available because newer Quartus versions have dropped APEX-20K synthesis support - legacy toolchains are required. The 144-TQFP package is also obsolete for new PCB designs; consider migrating to Cyclone or MAX II families for ongoing production.
