The Intel EP20K1000CF672I9 is a member of the APEX 20KC family of high-density SRAM-based FPGAs, integrating 1,000,000 system gates and 38,400 logic elements in a 672-ball FineLine BGA (FC-FBGA) package. The device is built on a 0.15 µm CMOS process, operates from a 1.71 V to 1.89 V core supply with a 1.8 V nominal, and supports up to 508 user I/O plus 4 dedicated inputs, making it one of the largest APEX 20KC variants available. An FPGA (Field-Programmable Gate Array) is a reprogrammable logic device in the programmable-logic IC hierarchy, sitting between complex PLDs and full custom ASICs. The APEX 20KC family combines Look-Up-Table (LUT)-based logic, embedded system blocks (ESBs) for memory and product-term logic, and a continuous, SRAM-based interconnect fabric, allowing designers to implement glue logic, datapath, memory, and bus interfaces on a single device. Positioned between CPLDs and structured ASICs, APEX 20KC was used in networking, telecom, and DSP-heavy designs of its era. Key features of the EP20K1000CF672I9 include 1,000,000 typical gates, 38,400 logic cells, 250 MHz internal performance, embedded array blocks for distributed RAM and ROM, and MultiVolt I/O support for interfacing with 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic. The 'I' speed grade and industrial temperature suffix (-40 °C to +85 °C) suit industrial embedded applications. The 672-ball FineLine BGA package provides high board density and ample signal breakout for the 508 I/O count. Architecturally, the device uses a four-level hierarchical interconnect (MegaLAB, LAB, ESB, LE) with dedicated carry chains and cascade paths for arithmetic and high-speed datapath operations. Each embedded system block can be configured as a dual-port RAM, FIFO, or CAM, providing up to 540 Kibits of embedded memory without consuming logic resources. The 0.15 µm CMOS process was Intel's high-density node for APEX generation devices. Typical applications include high-speed data-path bridging, telecom backplane interfaces, DSP co-processing cards, industrial control boards, and ASIC prototyping. The high logic capacity and embedded memory make it suitable for multi-channel protocol converters, RAID controllers, and legacy networking line-card designs where pin compatibility with the APEX 20K family is required. When designing with the EP20K1000CF672I9, plan for multi-rail power sequencing (1.8 V core plus I/O banks), provide a JTAG header for in-system programming, and follow Altera AN-114 (Guidelines for APEX 20K Board Layout) for BGA escape and decoupling. The 672-ball FC-FBGA requires a 4-6 layer PCB with microvia or via-in-pad fan-out to maintain signal integrity at high toggle rates. This page synthesizes distributor pricing, APEX 20KC drop-in alternatives from the same family, and practical board-layout guidance not aggregated on a single manufacturer page, helping engineers source and integrate this legacy FPGA quickly.

The Altera (Intel) EP20K1000CF672I9N is a high-density APEX 20KC family FPGA delivering 1,000,000 system gates and 38,400 logic elements in a 672-ball FineLine BGA package. It is fabricated on a 0.15 µm CMOS process, operates from a 1.8 V core supply, and supports I/O standards up to LVTTL/LVCMOS with a maximum internal clock frequency of 250 MHz. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) — a semiconductor IC whose logic function is defined by the customer after manufacture. FPGAs sit at the top of the programmable logic hierarchy: PLD → CPLD → FPGA → System-on-Chip FPGA. They integrate configurable logic blocks (LABs), embedded memory (ESBs), and interconnect, and are used as flexible hardware platforms for digital signal processing, glue logic, and high-speed parallel processing. Key features of the EP20K1000CF672I9N include 38,400 logic cells, 384 maximum user I/O pins, embedded system blocks (ESBs) for on-chip RAM/CAM, dedicated clock management with up to four phase-locked loops (PLLs), and MultiVolt I/O supporting 1.8 V, 2.5 V, and 3.3 V interfaces. The 672-ball FineLine BGA package exposes the full I/O count and provides a thermally enhanced die-up substrate for improved heat dissipation. JTAG boundary-scan support (IEEE 1149.1) is provided for in-system programming and board-level test. Architecturally, the APEX 20KC combines a lookup-table (LUT)-based logic fabric with embedded system blocks that can each be configured as dual-port RAM, single-port RAM, ROM, or content-addressable memory (CAM). This hybrid LUT+ESB architecture lets designers implement both random logic and datapath/memory blocks on a single die without external SRAM. The 0.15 µm process gives a speed-grade advantage over the older APEX 20K family while remaining in-system programmable via SRAM configuration cells. Typical applications include telecommunications line cards, high-speed image and video processing pipelines, industrial motor control and factory automation controllers, military/aerospace signal processing (in conjunction with the corresponding -I industrial temperature grade), and ASIC prototyping where design teams validate million-gate designs before committing to mask production. When designing with this device, the design engineer must select the correct speed grade (-9 is the fastest), observe LVTTL/LVCMOS I/O bank power sequencing, and use Altera Quartus II for synthesis, place-and-route, and bitstream generation. Configuration memory is volatile — the device must be re-loaded from a PROM or microcontroller on every power-up. This page synthesizes distributor pricing, same-brand speed-grade and package alternatives from the APEX 20KC family, and practical design notes not consolidated in any single manufacturer document.

It is specified for commercial 0C to 85C operation at speed grade -2X and is fabricated on a 0.15 micron all-layer copper-metal process that yields up to 35% faster design performance than earlier APEX 20K devices. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs), embedded memory, embedded multipliers or DSP blocks, and a programmable interconnect fabric. FPGAs occupy the high-density tier of programmable logic devices, sitting above CPLDs and below ASICs in the taxonomy of digital logic ICs: programmable logic device (PLD) -> CPLD -> FPGA -> ASIC. APEX-20KE devices specifically combine look-up-table based logic with embedded array blocks (EABs) that can act as RAM, ROM, or FIFO memory. Key features include 508 user I/Os, 2560 macrocells, 1.6 ns propagation delay, multi-volt I/O support (1.8V, 2.5V, 3.3V) on a 1.8V core supply, embedded CAM and RAM, four phase-locked loops for clock management, and JTAG-based IEEE 1149.1 boundary-scan testing. The device integrates LVDS, LVTTL, LVPECL, and PCI-compatible I/O standards, enabling direct interfacing with high-speed peripherals and backplanes. The EP20K1000EFI672-2X uses a symmetric LUT-based architecture with embedded system blocks (ESBs) that can be configured individually as either logic or memory. Its high gate count, 488 pins of user I/O, and embedded multipliers make it suited for DSP pipelines, custom processor implementations, and high-bandwidth glue logic. Compared with smaller APEX-20KE siblings, this 1M-gate device is the densest in the family. Typical applications include telecom line cards, network routers, custom DSP accelerators, high-speed image processing pipelines, and industrial control processors. The wide I/O count also makes it usable as a multi-protocol bridge or as a system-on-chip integrator in legacy 32-bit and 16-bit processor designs. When designing with this part, plan power sequencing carefully because the 1.8V core and multi-voltage I/O rails ramp independently; use the JTAG port for in-system programming and rely on the four PLLs to derive multiple clock domains without external clock buffers. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that supplement the manufacturer datasheet and help engineers shorten the selection cycle.
EP20K100BC356-1 - APEX-20K FPGA 100K Gates 356-BGA | Intel
The Intel (Altera) EP20K100BC356-1 is a member of the APEX-20K family of Field Programmable Gate Arrays (FPGAs) that combines logic, embedded system blocks (ESBs), and high-speed I/O in a single programmable device. The APEX-20K family uses a 0.15-micrometer all-layer copper-metal CMOS process, fabricated on a 35x35 mm 356-pin LBGA substrate, and integrates 53,248 bits of embedded RAM with up to 4,160 logic elements. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement any digital logic function. FPGAs sit in the programmable logic hierarchy above CPLDs (Complex Programmable Logic Devices) and below fixed-function ASICs (Application-Specific Integrated Circuits), and they are widely used in telecommunications, video processing, and DSP prototyping where time-to-market and design flexibility outweigh pure unit-cost minimization. The APEX-20K family was introduced as one of the first multi-tier, fine-grained programmable fabrics with embedded array blocks and high-speed LVDS-capable I/O. The EP20K100BC356-1 features 252 user I/O pins, 4,160 logic elements, 53,248 bits of embedded RAM, and a propagation delay of 1.6 ns at the standard -1 speed grade. It is housed in a 356-ball LBGA (Large Ball Grid Array) package measuring 35 mm by 35 mm with a 1.27 mm pitch. The device operates from a 1.71 V to 1.89 V core supply (typical 1.8 V) with separate VCCIO banks for I/O voltage flexibility. Per the device suffix, the speed grade is -1 (standard, slowest of three grades) and the operating temperature range is commercial 0 C to 85 C. Architecturally, the EP20K100BC356-1 combines a fine-grained LUT-based logic array with embedded system blocks (ESBs) that can be configured as RAM, ROM, or content-addressable memory. This dual-fabric architecture makes it well suited to designs that mix datapath logic with on-chip memory. The device supports JTAG (IEEE 1149.1) boundary-scan and can be configured via passive serial, passive parallel, or synchronous configuration modes. Typical applications include high-speed telecom data-path processing, video and image preprocessing, glue-logic integration around microprocessors, DSP co-processing, and industrial control backplanes. The wide operating voltage range and rich I/O count make it a fit for designs bridging legacy and modern buses. Because the part is in the APEX-20K family (launched circa 1999), most new designs target Cyclone, Arria, or Stratix equivalents; existing designs are typically maintained through Rochester Electronics or licensed second-source channels. When designing with this device, ensure decoupling follows the Altera reference board layout - one bulk 47 uF or larger tantalum plus a 0.1 uF ceramic per VCC pin pair is typical. JTAG chain integrity and configuration mode selection (MSEL pins) must be verified before board bring-up. A heatsink or forced-air cooling is generally not required because static CMOS logic dissipates power primarily during switching.

With its high I/O count and embedded memory, the EP20K100CB356C7ES is well suited for multi-channel data acquisition and protocol bridging designs. When designing with the APEX20K family, pay close attention to power sequencing - the core 1.8 V supply must ramp before I/O supplies to avoid latch-up. The Quartus development toolchain (legacy MAX+PLUS II for older designs) supports this device, providing synthesis, place-and-route, and timing analysis. Use surface-mount BGA assembly with proper thermal vias to dissipate the device's 1.5-2 W typical power.

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.

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.

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. This page synthesizes distributor pricing, exact-package drop-in alternatives from the APEX-20K family, and practical configuration/PCB guidance not consolidated on a single manufacturer datasheet.
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.

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 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.

The Intel (formerly Altera) EP20K100CQ208C7 is a member of the APEX20K family of SRAM-based FPGAs delivering 100,000 typical gates in a 208-pin Plastic Quad Flat Pack (PQFP/QFP) package. The device integrates 4,160 logic elements, 53,248 RAM bits, and 159 user I/O pins, supporting LVTTL, LVCMOS, and PCI I/O standards for flexible system integration. Key specifications include a core voltage of 1.8V, a maximum operating frequency of 180 MHz, and on-chip PLL support for clock management. The 'C7' speed grade indicates a 7 ns pin-to-pin logic delay, while the 'C' suffix denotes the commercial temperature range of 0C to +85C. The 208QFP package provides a perimeter I/O architecture ideal for through-hole-style PCB assembly or socketed 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. The device integrates 4,160 logic elements, 53,248 typical gates, and 32,768 bits of embedded RAM across 159 user I/O pins, making it a flexible platform for medium-density programmable logic designs. The 'C' speed grade designates a commercial 0.7 ns pin-to-pin logic delay tier for the APEX-20KE family. A Field Programmable Gate Array (FPGA) is a reprogrammable semiconductor device containing an array of configurable logic blocks (CLBs), embedded memory, and programmable routing interconnects that engineers can tailor to a custom digital function after manufacture. FPGAs occupy a specific tier in the programmable logic hierarchy: below them sit CPLDs (Complex Programmable Logic Devices) for glue logic, and above them sit ASICs and structured ASSPs for high-volume fixed-function designs. The APEX-20KE family targets multi-MHz datapath, bus-interface, and DSP-front-end designs where neither a CPLD's limited density nor an ASIC's NRE cost is acceptable. Key features of the EP20K100CQ208C7ES include 4,160 logic elements (LEs), 32,768 bits of embedded SRAM, up to 159 user I/O pins, and a true MultiVolt I/O interface that supports 2.5V/3.3V/5V mixed-voltage operation. The architecture combines look-up table (LUT)-based logic with dedicated carry chains, embedded memory blocks, and a four-phase PLL clock network. Embedded signal-processing capability and dedicated FastTrack interconnect routing allow efficient implementation of 16-bit multipliers, FIFOs, and wide datapath functions. Typical applications include telecommunications line-card glue logic, industrial machine-control interface bridging, flat-panel display timing controllers, PCI/ISA bus peripherals, and legacy ASIC prototype replacements. The BFQFP-208 footprint also makes it usable as a drop-in for existing APEX-20K / APEX-20KE designs requiring a logic upgrade. When designing with this part, ensure your I/O assignments respect the bank voltage groupings and that configuration is provided via the supported passive serial, parallel, or JTAG modes. The 208-pin PQFP package has substantial thermal mass but limited PCB-side cooling - keep sustained toggle rates below the package's recommended 1.0W dissipation budget at commercial ambient.

The device integrates an array of Logic Array Blocks (LABs), Enhanced Logic Elements (ELEs), and a MultiCore interconnect, providing 53,248 bits of embedded system blocks (ESB) for RAM or ROM functions and 100,000 bits of dedicated RAM. Speed grade C8 places the part in the mid-speed bin for industrial and commercial applications. An FPGA (Field-Programmable Gate Array) is a reconfigurable semiconductor device composed of programmable logic blocks, interconnect, and I/O cells that engineers can configure after manufacturing to implement custom digital functions. APEX 20KE FPGAs sit in the mid-to-high density tier of the Altera product taxonomy: gate array -> programmable logic -> FPGA -> complex programmable logic device (CPLD) family neighbor. 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.
