EPF10K250EFC672-3 - 250K Gates FLEX 10KE FPGA 2.5V 672-BGA | Intel
The Intel (Altera) EPF10K250EFC672-3 is a high-density member of the FLEX 10KE family of SRAM-based, in-system programmable logic devices (PLDs), integrating up to 250,000 typical gates, 12,160 logic elements (LEs), and 655,360 bits of embedded array block (EAB) RAM in a 672-ball FineLine BGA package. It operates from a 2.5 V core supply, supports JTAG-based in-system programmability, and provides 470 user I/O pins organized across eight I/O banks. A Field-Programmable Gate Array (FPGA) is a programmable logic device whose architecture combines an array of configurable logic blocks (CLBs / LEs), programmable routing channels, and block memory resources that the user can reconfigure after PCB assembly. FPGAs occupy a tier above traditional PLDs and below ASICs in the programmable-logic hierarchy: ASIC < structured ASIC < FPGA (high-end, e.g. Stratix, Virtex) < mid-range FPGA (e.g. FLEX 10KE, Cyclone) < CPLD. The FLEX 10KE family is Altera/Intel's mid-range, 2.5 V generation introduced in the late 1990s and still used in long-life-cycle industrial, telecom, and military designs where the toolchain (MAX+PLUS II / Quartus) is well understood. Key features of the EPF10K250EFC672-3 include 12,160 LEs, 655,360 bits of embedded memory (EABs), 392 LABs, multi-volt I/O support (1.5 V, 1.8 V, 2.5 V, 3.3 V) via bank-selectable supply rails, dedicated high-speed clock networks and phase-locked loops, JTAG (IEEE 1149.1) boundary-scan and ISP, and 470 user I/Os. The "-3" speed grade indicates the fastest commercial timing bin in the FLEX 10KE family, with internal block frequencies up to ~150 MHz in the device family. The architecture combines Logic Array Blocks (LABs) of 8 LEs each with Embedded Array Blocks (EABs) of 2,048 bits each, giving a flexible mix of distributed LUT logic and block RAM. MultiVolt I/O allows the EPF10K250E to bridge 5.0 V, 3.3 V, 2.5 V, 1.8 V and 1.5 V logic on the same die without external level shifters - critical for legacy backplane designs where multiple supply rails coexist. Typical applications include telecom line-card glue logic, industrial control backplanes, ASIC prototyping, military/aerospace (qualified per the -3 commercial grade), and PCI bridge/interface controllers where the high I/O count and EAB RAM are useful. Designers migrating from the FLEX 10K family gain roughly 2x density and 50% lower power from the 10KE process shrink to 0.25 µm / 2.5 V core. When designing with this device, ensure the 672-FBGA land pattern is correctly implemented (1.0 mm pitch per the package code) and that all four JTAG pins (TCK, TMS, TDI, TDO) plus the nCONFIG, nSTATUS, CONF_DONE and DCLK (or DATA, etc.) configuration pins are routed to accessible signals for in-system programming. The device is in-system reconfigurable but the configuration memory is volatile, so an external configuration PROM (EPC2, EPC8 or EPC16) is required for stand-alone boot.

EPF10K250EFI672-3 - 250K Gate FLEX 10KE FPGA 672-FBGA | Intel
The Intel EPF10K250EFI672-3 is a high-density FLEX 10KE family FPGA providing up to 250,000 typical gates in a 672-ball FineLine BGA package. It integrates 470 user I/O pins, 12 embedded array blocks (EABs) with dual-port capability up to 16-bit width per EAB, and a general-purpose logic array with SRAM-based configuration cells. The device operates from a 2.5 V core supply with 5.0 V tolerant I/O and is rated for the commercial 0 °C to 70 °C temperature range. A Field-Programmable Gate Array (FPGA) is a programmable logic device that combines configurable logic blocks, programmable interconnect, and I/O cells into a single semiconductor die. FPGAs sit within the broader hierarchy of programmable logic devices (PLDs) -> complex programmable logic devices (CPLDs) -> FPGAs -> system-on-a-programmable-chip (SOPC) platforms, and are widely used to implement glue logic, digital signal processing, custom bus interfaces, and prototype ASIC functionality without the NRE cost of a masked gate array. The FLEX 10KE family uses a CMOS SRAM process that allows in-system reconfiguration via an industry-standard configuration interface such as ByteBlaster or JTAG. Key features of the EPF10K250EFI672-3 include up to 250,000 typical gates (over 100,000 usable logic elements), 470 user I/O pins for high pin-count designs, dual-port EABs of up to 16 Kbits each for embedded memory or multiplier functions, multiVolt I/O supporting 2.5 V and 3.3 V interfaces, and JTAG-compliant boundary-scan test. The 672-ball FineLine BGA package (1.27 mm pitch) supports board densities typical of telecom line cards and high-performance data-path designs. The architecture uses a four-input look-up table (LUT) logic element backed by continuous FastTrack interconnect, achieving tpd in the 0.4 ns class for the -3 speed grade. Each EAB can implement true dual-port RAM with independent read/write clocks, enabling FIFO and dual-buffer designs without external memory. The FLEX 10KE was historically targeted at glue-logic integration and is now commonly found in legacy equipment maintenance and industrial-control retrofits. Typical applications include telecommunications line-card interface logic, industrial machine control, custom peripheral bridges for PCI/ISA buses, and prototype ASIC replacement. With 470 user I/Os the device can sink several wide buses in parallel without external muxing. The FLEX 10KE supports EDIF 2 0 0 and 3 0 0, LPM, VHDL, and Verilog design entry through the Altera MAX+PLUS II and Quartus tool chains. When designing with this part, ensure proper decoupling with 0.1 µF ceramic capacitors close to every VCC pin and a single bulk 33 µF tantalum per supply island. The SRAM cells are volatile, so an external configuration PROM (EPC2 or EPC8) must be present on the board to load the bitstream at power-up. Operating temperature and speed-grade suffixes must match the system ambient and timing budget.

EPF10K250EGC599-1 - FLEX 10K FPGA 250K Gates 599-BPGA | Intel
The Intel (formerly Altera) EPF10K250EGC599-1 is a high-density FLEX 10K embedded array FPGA housed in a 599-ball ceramic Pin Grid Array (HIPGA / BPGA) package with a commercial temperature grade. As a member of the FLEX 10K family, it integrates up to 250,000 equivalent system gates with embedded array blocks (EABs), delivering up to 40,960 logic elements and 12,160 flip-flops in a single SRAM-based fabric. An FPGA (Field-Programmable Gate Array) is a reprogrammable semiconductor that lets engineers implement arbitrary digital logic through a configurable matrix of lookup tables, flip-flops, routing, and hard IP blocks. FPGAs sit at the top of the programmable logic hierarchy: ASIC < CPLD < FPGA, and are used when design flexibility, parallel processing, or rapid prototyping outweigh the per-unit cost advantages of masked ASICs. The FLEX 10K family was Altera's first embedded-array family, where each EAB provides up to 2 Kbits of dual-port RAM, blurring the boundary between FPGA and gate-array ASIC designs. Key features of the EPF10K250EGC599-1 include 470 user I/O pins, multi-voltage I/O support (5.0 V PCI-compliant operation), on-chip SRAM distributed across EABs, in-system programmability via the serial configuration EPROM interface, JTAG boundary-scan (IEEE 1149.1), and 6 dedicated clock inputs with 2 dedicated FastROW interconnects. The HIPGA-599 ceramic package supports high-pin-count designs and provides superior thermal and mechanical performance versus plastic BGA equivalents. Architecturally, the FLEX 10K family pairs a fine-grained logic element array with coarse-grained embedded array blocks, giving designers both high logic density and predictable memory throughput. Logic elements include a 4-input LUT, a programmable register, dedicated carry-chain logic, and a cascade chain. The device is fabricated on a 0.42 µm CMOS SRAM process, and configuration is volatile — design data must be loaded from an external serial or parallel EPROM at every power-up. Typical applications include telecommunications line cards, industrial control and instrumentation glue logic, ASIC prototyping, PCI bus bridges, and high-speed data-path controllers. The 470 I/O pins are sufficient to absorb wide parallel bus interfaces such as PCI, SDRAM, and legacy ISA peripherals, while the EABs handle FIFO and dual-port memory needs on-chip. When designing with this part, provide a clean 5 V supply rail and a configuration EPROM (EPC2 or compatible) on every board. Because the FLEX 10K family is mature and has been NRND since the early 2000s, engineers planning new designs should evaluate Cyclone, MAX 10, or Agilex families instead — the EPF10K250EGC599-1 is best reserved for sustaining existing production.

EPF10K250EGC599-2 - FLEX 10KE FPGA, 250K Gates, 599-BCPGA | Intel
The Intel (Altera) EPF10K250EGC599-2 is a high-density FLEX 10KE family FPGA featuring 250,000 typical gates and 12,160 logic elements, housed in a 599-pin ceramic PGA (CPGA-599 / HIPGA-599) package. The "-2" speed grade designates a mid-range AC performance tier, while the commercial temperature grade makes this part suitable for benign-environment designs. The device integrates embedded array blocks (EABs) for memory implementation, each EAB providing 2,048 bits of RAM, and supports SRAM-based configuration with in-system programmability via the FLEX 10K family configuration interface. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit built from an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that engineers can reconfigure after manufacture to implement arbitrary digital logic. FPGAs sit within the broader hierarchy of programmable logic devices (PLDs) between simple CPLDs and modern high-end SoC FPGAs. The FLEX 10KE family uses a fine-grained architecture with built-in SRAM look-up tables and dedicated carry chains, placing it in the mid-1990s generation that pioneered embedded array blocks for on-chip memory. Key features include 12,160 logic elements (LEs), approximately 250,000 typical gates, 12 embedded array blocks providing up to 24,576 RAM bits, 4 phase-locked loops (PLLs) for clock management, and multi-standard I/O support. The device operates from a 5V core supply and supports JTAG boundary-scan testing per IEEE 1149.1. The CPGA-599 ceramic package provides hermetic sealing for high-reliability applications. The FLEX 10KE architecture uses a continuous SRAM-based configuration cell backed up by EPROM programming cells on each LE, enabling both in-system reprogrammability and one-time-programmable mode. Embedded array blocks implement RAM, ROM, or specialized logic functions, while the FastTrack interconnect provides predictable timing for high-speed designs. The 599-pin CPGA package supports 470 user I/O pins, which is substantial for a mid-1990s FPGA. Typical applications include telecommunications switching infrastructure, industrial control systems, military and aerospace digital logic prototypes, high-reliability embedded computing, and legacy design replacements. The FLEX 10KE family was widely adopted in network processing equipment and DSP co-processing designs during its product life. The CPGA-599 ceramic package also makes it suitable for applications requiring hermetic sealing, such as downhole oil and gas instrumentation and military field equipment. When designing with this part, verify that your synthesis tool still supports the FLEX 10KE family, since modern Intel Quartus has dropped legacy device support beyond Cyclone series. Engineers maintaining legacy designs should retain original MAX+PLUS II or Quartus II version 9.0 design databases for bitstream regeneration. Note that the EPF10K250E is a mature product approaching end-of-life - new designs should target Cyclone or MAX 10 series.

EPF10K250EGC599-3 - 250K Gate FLEX 10KE FPGA, 599-PGA | Intel
The Intel (formerly Altera) EPF10K250EGC599-3 is a high-density FLEX 10KE family FPGA featuring 250,000 typical gates, 12,160 logic elements (LEs), and 409,600 bits of embedded SRAM in a 599-pin Pin-Grid Array (PGA) ceramic/heat-dissipating package. Speed grade -3 indicates the standard performance bin, and the device is graded for commercial operating temperature (0C to +70C). A Field-Programmable Gate Array (FPGA) is a programmable logic device that combines programmable logic elements, configurable interconnect, and dedicated hard IP blocks (memory, multipliers, I/O) on a single CMOS die. FPGAs sit in the broader hierarchy of programmable logic devices (PLDs) above simple PLDs (SPLDs) and complex PLDs (CPLDs), and they compete with ASICs at lower volumes and with microcontrollers/DSPs in parallelizable workloads. The FLEX 10KE family was one of Altera's flagship high-density SRAM-based families, using SRAM configuration cells that allow in-system reconfiguration via a serial or parallel configuration interface. Key features of the EPF10K250EGC599-3 include 12,160 logic elements, 12 embedded array blocks (EABs) providing 409,600 bits of dual-port RAM, a maximum of 470 user I/O pins, MultiVolt I/O supporting 3.3V/2.5V/1.8V interface standards, and a global clock network. The device is built on a 0.22-micron CMOS SRAM process with 5V tolerant I/O and operates from a 3.3V core supply. Typical applications include high-throughput digital signal processing, telecommunications backplane glue logic, industrial motion control, and legacy system upgrades where the existing PCB was designed around a 599-pin PGA footprint. Designers often migrate to surface-mount FPGAs in new designs, but the PGA package remains useful for prototyping, ruggedized environments, and aerospace/defense programs. When designing with this part, ensure the configuration PROM (typically an EPC2 or EPC16) is sized correctly for the bitstream and that the JTAG chain order is preserved. The 599-pin PGA is mechanically demanding; use a proper socket and verify pin-1 orientation before board bring-up. Plan for JTAG boundary-scan verification as a first-pass test.
EPF10K250EGI599-3 - FLEX 10KE FPGA 250K Gates 599-PGA | Intel
The Intel (formerly Altera) EPF10K250EGI599-3 is a high-density FLEX 10KE embedded-programmable logic device (PLD) featuring approximately 250,000 typical gates and 12,160 logic elements (LEs), housed in a 599-pin ceramic/ceramic-equivalent Pin Grid Array (PGA) package. The device operates from a 2.5 V core supply and is rated for the industrial temperature range (–40 °C to +85 °C), with a –3 speed grade indicating the fastest commercial/industrial performance bin for this family. What is an embedded PLD/FPGA? A Field-Programmable Gate Array (FPGA) is a reconfigurable semiconductor containing an array of configurable logic blocks (CLBs / LEs), programmable interconnect, and dedicated I/O and memory resources. The FLEX 10KE family extends the original FLEX 10K architecture by adding embedded array blocks (EABs) for synchronous RAM and ROM functions, making the family suitable for high-density glue-logic, datapath, and system-on-chip prototyping. FPGAs sit within the broader hierarchy of programmable logic devices (PLDs) -> programmable logic -> digital semiconductor ICs. Key features include up to 12,160 logic elements, 40,960 RAM bits distributed across embedded array blocks (EABs), 488 maximum user I/O pins, and PCI-compliant I/O support. The device supports in-system configuration via passive serial, active serial, and JTAG modes, with multi-volt I/O capability for interfacing with 2.5 V, 3.3 V, and 5 V buses. The –3 speed grade delivers the shortest pin-to-pin propagation delays available in this family. The FLEX 10KE family is built on a 0.25 µm CMOS SRAM process with a 2.5 V core. Configuration data is stored in SRAM cells, requiring a configuration EPROM or controller at every power-up. The architecture combines a fine-grained logic fabric (each LE = one 4-input LUT plus a flip-flop) with coarse-grained EABs of 2,048 bits each, allowing designers to balance random logic and dense memory in a single device. Typical applications include high-speed telecommunications backplanes, industrial control and instrumentation, ASIC prototyping, DSP coprocessor interfaces, and legacy PCI-bus glue logic. The large logic capacity and rich memory resources make the EPF10K250E one of the most popular "workhorse" FPGAs of its generation, still in use in long-lifecycle industrial and military programs. Designers should note that the 599-pin PGA package is a through-hole pin-grid-array that requires a socket or plated-through-hole PCB and is not compatible with modern lead-free surface-mount reflow profiles. Configuration memory is volatile: the device loses its bitstream on every power-down and must be reconfigured at boot via an EPC configuration EPROM, a microcontroller, or JTAG. Engineers targeting new designs should consider Cyclone IV/V or MAX 10 as modern, lower-power, surface-mount alternatives. This page consolidates distributor pricing, same-brand drop-in alternatives from the FLEX 10KE family, and practical design notes not assembled in any single manufacturer datasheet, giving procurement and engineering teams a single decision-ready reference.
EPF10K30ABC356-1 - 30K Gate FLEX-10KA FPGA, 356-BGA | Intel
Intel (Altera) EPF10K30ABC356-1 is a member of the FLEX-10KA embedded programmable logic device (PLD) family, delivering 30,000 typical gates in a 356-ball LBGA package. It is built on a 3.3V SRAM-based architecture with an embedded array block (EAB) for on-chip memory and specialized megafunctions, providing system-on-a-programmable-chip (SOPC) integration. The device includes 246 user I/Os, 216 logic array blocks (LABs), and operates from a 3.0V to 3.6V supply. A field-programmable gate array (FPGA) is a type of integrated circuit designed to be configured by the customer or designer after manufacturing. FPGAs belong to the broader programmable logic device (PLD) family, which sits within the semiconductor hierarchy of logic ICs, integrated circuits, and finally electronic components. FPGAs differ from application-specific integrated circuits (ASICs) in that their function is not hard-wired at fabrication, allowing the same silicon to implement many different digital designs through configuration bitstream loading. Key features include 30,000 typical gates (119,000 maximum), 12 embedded array blocks (EABs) totaling 24 Kbits of RAM, 1,728 logic elements (LEs), 246 user I/Os, and in-system programmability through the serial passive (PS) configuration scheme. The part is specified for the commercial temperature grade and is built on a 0.42-micron CMOS process. The 356-LBGA (low-profile BGA) package has 35 mm x 35 mm body dimensions suitable for high-density PCB layouts. The FLEX-10KA architecture combines a logic array of LABs with a row of EABs. Each EAB provides 2 Kbits of dual-port RAM, allowing efficient implementation of memory-intensive functions such as FIFO buffers, lookup tables, and DSP datapaths without consuming general-purpose logic. Interconnect is provided through FastTrack continuous routing channels, which minimize interconnect delay for predictable timing closure. The device supports multiple I/O standards including 5V, 3.3V, and 2.5V LVCMOS/LVTTL for mixed-voltage system design. Typical applications include glue-logic consolidation in telecom line cards, custom peripheral interfacing for industrial controllers, prototyping bridges between legacy ASICs and microcontrollers, and DSP pre/post-processing blocks in audio and video pipelines. The device is well suited for medium-density designs in the 20K-50K gate range where the embedded memory blocks reduce overall system cost. When designing with this part, note that configuration data must be loaded from an external serial PROM (EPC1, EPC2) or via a microcontroller at every power-up because the SRAM cells are volatile. JTAG boundary-scan and programming via the ByteBlasterMV cable are supported for in-system updates. The 356-ball BGA requires PCB-level assembly with X-ray inspection of solder joints and adequate thermal relief for the commercial temperature range of 0C to +70C. This page synthesizes distributor pricing, FLEX-10KA family cross-references, and practical design notes not found in the original manufacturer datasheet.
EPF10K30AQC208-1N - 30K Gate FLEX-10KA FPGA, 208-PQFP | Altera
The Altera (Intel) EPF10K30AQC208-1N is a member of the FLEX 10KA family of Field Programmable Gate Arrays (FPGAs) housed in a 208-pin Plastic Quad Flat Pack (208-PQFP, 28x28 mm) package. The device integrates approximately 30,000 typical gates with 1,728 logic elements (LEs), 12,288 bits of embedded RAM, and 147 user I/O pins. It operates from a 3.0 V to 3.6 V core supply (commercial, 0 °C to 70 °C temperature grade) and supports in-system programmability via SRAM configuration. A Field Programmable Gate Array (FPGA) is a type of integrated circuit that can be configured by the customer or designer after manufacturing to implement arbitrary digital logic. FPGAs sit in the programmable-logic hierarchy above PLDs/CPLDs and below fixed-function ASICs, and are widely used for glue logic, prototyping, DSP, and high-speed interface bridging. The FLEX 10KA family from Altera was the industry's first embedded programmable logic family providing System-on-a-Programmable-Chip (SOPC) integration through an embedded array block (EAB) architecture, allowing designers to mix dedicated RAM/ROM with LUT-based logic on a single die. Key features of the EPF10K30AQC208-1N include 1,728 logic elements, 12 Kbits of embedded memory, 147 user I/Os, an internal frequency up to 80 MHz, and SRAM-based configuration that supports rapid prototyping and field updates. The '-1N' speed grade targets the commercial temperature range with standard timing closure. The 208-PQFP surface-mount package uses gull-wing leads, making it compatible with conventional SMT assembly lines and rework processes. The FLEX 10KA architecture combines a coarse-grained Embedded Array Block (EAB) used to implement memory and complex arithmetic functions with a fine-grained Logic Array Block (LAB) used for general-purpose logic. The EPF10K30A places 6 EABs alongside 216 LABs on a 0.42 µm CMOS process, with each LAB containing 8 LEs. This hybrid fabric is efficient for datapath-heavy designs where distributed RAM and lookup tables coexist. Typical applications for the EPF10K30AQC208-1N include telecom interface bridging, industrial control glue logic, legacy peripheral bus adaptation (PCI, ISA, VME), high-speed prototyping of ASIC replacements, and embedded memory buffering. Its 3.3 V core, 147 user I/Os, and SRAM programmability also make it attractive for educational platforms and FPGA training kits where the PQFP package simplifies hand-soldering. Designers should plan a 3.3 V rail with adequate decoupling, route 147 user I/Os across four I/O banks with consistent bank voltage references, and select the correct configuration device (EPC2 or compatible) for SRAM configuration at power-up. Compared to modern flash-based FPGAs, the EPF10K30AQC208-1N requires an external configuration memory and is not 5 V tolerant on I/Os at the core's 3.3 V CMOS levels. This page synthesizes distributor stock levels, cross-family FLEX 10KA drop-in options, application-specific companion parts, and practical design notes that go beyond what the original Altera datasheet provides alone.
EPF10K30AQC208-3 - 30K Gates FLEX-10KA FPGA, 208-PQFP | Altera
The Altera EPF10K30AQC208-3 is a member of the FLEX-10KA family of Field Programmable Gate Arrays (FPGAs) featuring 30,000 gates, 1,728 logic cells, 12,288 bits of embedded memory, and 147 user I/Os, housed in a 208-pin Plastic Quad Flat Pack (PQFP) package. It is fabricated on a 0.3 µm CMOS process, operates from a 3.3 V core supply, and is specified for commercial temperature grades with a -3 speed grade. An FPGA (Field Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that can be re-programmed to implement arbitrary digital logic. Within the broader taxonomy, the FLEX-10KA belongs to the SRAM-lookup-table-based FPGA family, sitting between simple CPLDs and modern high-density FPGAs. It supports System-on-a-Programmable-Chip (SOPC) integration by combining embedded array blocks (EABs) for megafunctions such as efficient memory and specialized logic functions with general-purpose logic, allowing designers to implement microcontrollers, DSP functions, and glue logic on a single device. Key features of the EPF10K30AQC208-3 include 216 Logic Array Blocks (LABs) organized as 24 Logic Elements (LEs) per LAB, embedded array blocks for memory and DSP-style functions, MultiVolt I/O support for interfacing with 5.0 V, 3.3 V, 2.5 V, and 1.8 V logic without external level shifters, JTAG-based in-system programmability via IEEE 1149.1, PCI pull-up clamping diodes, slew-rate control, and open-drain output options configurable pin-by-pin through Altera logic options. The device uses Altera's Look-Up Table (LUT)-based architecture with continuous FastTrack routing, delivering predictable timing closure and supporting frequencies up to 125 MHz in this speed grade. It is supported by the legacy Altera MAX+PLUS II and Quartus design flows, although modern Quartus releases no longer include this family, and designers using this device typically retain the original MAX+PLUS II toolchain or maintain pre-generated programming files. Typical applications include telecommunications line cards, industrial control and factory automation, legacy PCI interface bridges, and embedded control logic that requires moderate gate counts with on-chip memory. The 208-PQFP package also makes the EPF10K30AQC208-3 a common choice for board-level prototyping where fine-pitch BGA packages are not practical. When designing with this device, attention should be paid to the MultiVolt I/O configuration: VCCINT must be tied to 3.3 V while VCCIO can be set independently to support mixed-voltage buses. Configuration via JTAG or a serial/configuration EPROM must also be considered; the device is volatile (SRAM-based) and loses configuration on power-down, so an external configuration memory is required for production designs. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the Altera datasheet alone.
EPF10K30AQC208-3N - 30K Gates FLEX 10KA FPGA, 208-PQFP | Intel / Altera
The Intel / Altera EPF10K30AQC208-3N is a member of the FLEX 10KA family of SRAM-based Field-Programmable Gate Arrays (FPGAs) integrating 30,000 typical gates, 1,728 logic elements (cells) and 12,288 bits of embedded memory into a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. Built on a 0.3 µm CMOS process and supplied from a 3.3 V core, the device delivers up to 125 MHz of system performance and exposes 147 user I/O pins for digital interfacing. The “-3” speed grade and the “N” lead-free suffix confirm commercial temperature operation and Pb-free assembly, while the “QC208” package code denotes the 208-pin QFP outline used across the FLEX 10KA density range. A Field-Programmable Gate Array (FPGA) is a semiconductor device whose logic function is defined by user-loaded configuration memory rather than hard-wired mask layers. FPGAs sit in the programmable-logic hierarchy between simple Complex Programmable Logic Devices (CPLDs) and high-density Application-Specific Integrated Circuits (ASICs), giving engineers hardware-reconfigurable glue logic, datapath acceleration, and bus-interface bridging without any NRE charges. The FLEX 10KA family was Intel / Altera’s first generation to embed dedicated array blocks (EABs) for efficient RAM and DSP megafunctions, marking the transition from pure glue logic to System-on-a-Programmable-Chip (SOPC) integration. Key features of the EPF10K30AQC208-3N include 216 Logic Array Blocks (LABs) organised in rows and columns, embedded array blocks for dual-port RAM and ROM, MultiVolt I/O allowing mixed-voltage interfacing on the same die, pin-controlled PCI-clamping diodes, slew-rate control, and open-drain output options. The PLICE antifuse-style configuration scheme is replaced here by an SRAM configuration cell, supporting in-system reconfigurability via the serial or parallel configuration port. The exposed MultiVolt interface simplifies bridging between 3.3 V cores and 5.0 V or 2.5 V peripherals. Typical applications include PCI bus controllers, telecommunications line cards, industrial glue logic, protocol bridging (UART, I²C, SPI bridges), legacy ASIC replacement, and parallel DSP datapath prototyping. The combination of 12 Kbit embedded memory, 147 I/Os and 125 MHz Fmax makes it well-suited to mid-density control-plane designs where cost per gate dominates over raw performance. When designing with this part, allocate the configuration PROM or microcontroller interface early in the schematic because FLEX 10KA devices do not retain their configuration when power is removed. The MultiVolt VCCIO rail must be tied before or simultaneously with VCCINT to avoid latch-up. Use the Quartus / MAX+PLUS II Legacy device libraries and observe the 208-PQFP thermal envelope (θJA ≈ 35 °C/W typical) when calculating airflow in dense line-card layouts.

EPF10K30AQC240-1 - 30K FLEX-10KA FPGA, 240-PQFP | Intel/Altera
The Intel (formerly Altera) EPF10K30AQC240-1 is a FLEX-10KA family Field Programmable Gate Array (FPGA) integrating 30,000 typical gates, 1,728 logic elements, and 12,288 bits of embedded SRAM in a 240-pin Plastic Quad Flat Pack (PQFP / BFQFP) package. Built on a 0.42 µm CMOS process, the device offers 189 user I/O pins, a 0.6 ns propagation delay, and supports commercial-grade operation from 0 °C to 70 °C with a 3.3 V core supply. What is an FPGA? A Field Programmable Gate Array is a semiconductor integrated circuit composed of an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that can be electrically reconfigured to implement custom digital logic. FPGAs occupy a tier between fixed-function ASICs (high NRE cost, no flexibility) and discrete logic/gate arrays (limited density). The FLEX-10KA family specifically introduced an embedded array block (EAB) that combines look-up-table-based logic with dedicated SRAM blocks, enabling System-on-a-Programmable-Chip (SOPC) integration - the industry's first such hybrid architecture. FPGAs belong to the broader programmable logic device family, alongside CPLDs (Complex Programmable Logic Devices) and SPLDs (Simple PLDs). Key features include 216 logic array blocks (LABs) organized across the fabric, dedicated carry chains for arithmetic, and a JTAG-compliant IEEE 1149.1 boundary-scan interface. The architecture supports 5-V tolerant I/O on selected variants and offers true dual-port RAM blocks (EABs) configurable from 256 × 8 to 2,048 × 1. Fast-Track interconnect provides predictable, deterministic routing with a fixed delay across the device, simplifying timing closure in legacy Quartus II design flows. Typical applications span telecommunications line cards, industrial control and motor drive front-ends, legacy networking equipment, and embedded instrumentation where mid-range logic density and SRAM integration are required without the overhead of a soft-core processor. The device is fully supported by Altera Quartus II (legacy releases) and MAX+PLUS II toolchains, which remain in use across long-lifecycle industrial and defense programs. Designers should evaluate the device's 0.6 ns pin-to-pin logic delay against system timing budgets, and confirm 3.3 V core / 5 V tolerant I/O compatibility with surrounding logic. Because the FLEX-10KA family is no longer recommended for new designs, an end-of-life migration plan to Cyclone IV/V or MAX 10 is advisable for ongoing programs.

EPF10K30AQC240-1N - 30K-Gate FLEX-10KA FPGA, 240-PQFP | Intel
The Intel (formerly Altera) EPF10K30AQC240-1N is a 30,000-gate FLEX-10KA family Field-Programmable Gate Array (FPGA) housed in a 240-pin Power Quad Flat Pack (PQFP/BFQFP) package. It integrates 1,728 logic elements (LEs) across 216 Logic Array Blocks (LABs) with 12,288 bits of embedded SRAM, providing approximately 30K typical gates of logic capacity for mid-complexity digital designs. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that combines configurable logic blocks, programmable interconnects, and I/O cells on a single die. The FLEX-10KA family is the industry's first embedded PLD family, providing System-on-a-Programmable-Chip (SOPC) integration with embedded array blocks (EABs) for memory-intensive functions such as FIFOs, RAM, and ROM. FPGAs sit within the broader hierarchy of programmable logic -> PLD -> digital IC -> semiconductor. Key specifications include 189 user I/Os, a maximum internal frequency of approximately 166.67 MHz, a propagation delay of 0.6 ns, and operation from a 3.3 V supply. The device is fabricated on a 0.3 µm CMOS process and supports the commercial temperature grade (0 °C to 70 °C). It features built-in low-skew clock distribution trees, FastTrack Interconnect for predictable interconnect delays, and tri-state emulation that supports in-system debugging. The EPF10K30AQC240-1N is built on Altera's Look-Up Table (LUT)-based architecture with continuous FastTrack routing, making timing closure more predictable than segmented interconnect schemes. The embedded array blocks (EABs) can each implement 2,048 bits of RAM, enabling efficient on-chip memory for DSP-style data paths and glue-logic functions. Typical applications include telecommunications glue logic, industrial control interfaces, legacy system prototyping, and embedded controller replacement where low-to-moderate gate counts are needed. Designers often select this part for upgrading older discrete-TTL designs into a single programmable device. When designing with this FPGA, ensure your JTAG chain handles the device's boundary-scan and configuration requirements, and verify timing closure at the -1 speed grade in your synthesis tool. Quiescent power is minimized by tying unused I/Os to a defined logic level through the Quartus pin assignment file.

EPF10K30AQC240-2N - 30K Gate FLEX-10KA FPGA | Intel / Altera
The Intel / Altera EPF10K30AQC240-2N is a 30,000-gate FLEX-10KA series Field Programmable Gate Array (FPGA) with 1,728 logic cells, 12,288 bits of embedded array memory, and 189 user I/O pins, housed in a 240-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. It operates from a 3.3V supply, is fabricated on a 0.3 µm CMOS process, and supports an internal maximum frequency of 142.86 MHz at commercial temperature grade (0 °C to 70 °C). An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the density of gate arrays with user programmability. FPGAs sit at the top of the programmable logic hierarchy — above SPLDs and CPLDs — and are used to implement arbitrary digital logic, glue logic, bus interfaces, and signal processing pipelines. The FLEX-10KA family specifically introduced an embedded array block (EAB) that holds dedicated SRAM blocks for memory functions, allowing the device to act as a System-on-a-Programmable-Chip (SOPC) building block. Key features of the EPF10K30AQC240-2N include 216 Logic Array Blocks (LABs), a built-in low-skew clock distribution tree, FastTrack® Interconnect continuous routing structure for predictable interconnect delays, tri-state emulation for board-level testing, and 100 % functional factory testing. The device supports both 3.3 V and 5.0 V I/O operation through selectable I/O standards, simplifying mixed-voltage system integration with legacy logic families. The device architecture combines logic elements grouped into LABs, EAB-based memory, and a hierarchical interconnect network. The embedded array blocks are configurable as wide SRAM blocks, while the logic array blocks contain 8 logic elements each. This hybrid architecture makes the EPF10K30AQC240-2N well-suited to designs that need both random logic and small-to-medium memory functions on a single chip. Typical applications include telecom line cards, industrial control, glue logic for microprocessor systems, custom peripheral controllers, prototype ASIC development, and legacy system maintenance where the original FLEX-10KA design must be reproduced. When designing with this FPGA, engineers should plan for the older 0.3 µm CMOS process — it draws higher quiescent current than modern 65 nm / 28 nm FPGAs, and the 240-pin PQFP is a through-hole-friendly surface-mount package requiring careful thermal management at higher toggle rates.
EPF10K30AQC240-3 - 30K-Gate FLEX-10KA FPGA, 240-PQFP | Altera
The Altera EPF10K30AQC240-3 is a member of the FLEX-10KA family of SRAM-based FPGAs, delivering approximately 30,000 usable gates, 1,728 logic elements (cells), and 12,288 bits of embedded RAM in a 240-pin Plastic Quad Flat Pack (PQFP) package. According to the FLEX-10KA datasheet, this device is fabricated on a 0.3 µm CMOS process and operates from a nominal 3.3 V supply (3.0 V min, 3.6 V max), with 189 user I/O pins arranged in 216 logic array blocks (LABs). A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs), programmable interconnect, and programmable I/O cells. FPGAs belong to the broader category of programmable logic devices (PLDs), which sit hierarchically below ASICs in the digital design taxonomy. Unlike an ASIC, an FPGA can be reconfigured in the field after manufacture, making it ideal for prototyping, low-volume production, and designs that require post-deployment updates. The FLEX-10KA series was one of the first commercially successful "System-on-a-Programmable-Chip" (SOPC) families, integrating lookup-table-based logic with embedded array blocks (EABs) that can implement RAM, ROM, or multiplier functions. Key features of the EPF10K30AQC240-3 include 216 LABs, 189 programmable I/Os, 12,288 bits of embedded SRAM, a typical internal operating frequency around 125 MHz, and multi-voltage I/O support compatible with 3.3 V and 5 V interfaces. The "-3" speed grade designates a faster bin relative to the -1 and -2 grades, and the "C" in the part number indicates the commercial 0 °C to 70 °C temperature range. Architecturally, the FLEX-10KA device combines a fine-grained logic fabric (each LAB contains eight logic elements) with coarse-grained EABs of 2,048 bits each, allowing designers to balance random logic against memory-intensive functions in the same die. The 240-PQFP footprint (also referred to as 240-BFQFP or FQFP-240) is a gull-wing surface-mount package, suitable for reflow assembly and rework. Typical applications for the EPF10K30AQC240-3 include glue logic and bus bridging in industrial controllers, custom I/O expansion for legacy 3.3 V systems, prototype ASIC replacement, communication protocol bridging (UART, SPI, I2C, parallel buses), and educational/development platforms for HDL designers. The wide 5 V-tolerant I/O bank simplifies interfacing with TTL-era peripherals. When designing with this device, ensure that the Quartus or MAX+PLUS II toolchain version supports the FLEX-10KA family, as newer Quartus releases have dropped legacy device support. Provide clean 3.3 V power with adequate decoupling near each VCC/VCCIO pin pair, and respect the JTAG programming pinout for in-system configuration.

EPF10K30AQI208-3 - FLEX 10KA FPGA, 30K Gates, 208-PQFP | Altera
The Altera (now Intel) EPF10K30AQI208-3 is a member of the FLEX 10KA family of Field-Programmable Gate Arrays, offering 30,000 typical gates, 1,728 logic elements (LEs), 12,288 RAM bits, and 147 user I/Os, all housed in a 208-pin Power Quad Flat Pack (PQFP/BFQFP) package with industrial temperature grade. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows designers to configure digital logic blocks and interconnects after manufacture. The FLEX 10KA family was Altera's first embedded programmable logic family delivering System-on-a-Programmable-Chip (SOPC) integration, combining a logic array with an embedded array block (EAB) used for memory, multipliers, or specialized functions. Architecturally, an FPGA sits within the broader category of programmable logic -> logic IC -> integrated circuit -> semiconductor. The EPF10K30AQI208-3 is fabricated on a 0.30 µm CMOS process and operates from a 3.3 V core supply. It supports a maximum internal frequency of 125 MHz and is designed for 3.3 V PCI-compliant I/O with built-in Joint Test Action Group (JTAG) boundary-scan test circuitry compliant with IEEE Std. 1149.1-1990. The industrial temperature grade (-40 °C to +85 °C) makes this part suitable for harsher environments than the commercial-only EPF10K30AQC208-3 variant. Typical applications include telecommunications line cards, industrial control and factory automation, glue logic replacement for ASICs, PCI interface bridging, and legacy system upgrades where a 3.3 V, 5 V-tolerant I/O FPGA is required. Designers often select the FLEX 10KA family for new system bring-up because of its mature toolchain (Quartus), predictable timing, and long-term availability through the Altera-to-Intel transition. When designing with the EPF10K30AQI208-3, plan I/O assignments carefully because the PQFP package has limited power/ground pin count, which can constrain signal integrity for high-speed designs. Use the IEEE 1149.1 boundary-scan chain for board-level testing and consider the EPF10K30EQC208-3 (FLEX 10KE) as a drop-in migration path when higher performance or more LE capacity is needed.

EPF10K30AQI208-3N - 30K Gates FLEX-10KA FPGA 147 I/O 208-PQFP | Altera
The Intel (formerly Altera) EPF10K30AQI208-3N is a member of the FLEX-10KA embedded programmable logic family, delivering 30,000 gates, 1,728 logic cells, and 12,288 bits of embedded SRAM in a 208-pin Plastic Quad Flat Pack (PQFP / BFQFP) surface-mount package. It provides 147 user I/O pins, operates from a 3.3 V core supply, and supports MultiVolt I/O for interfacing with 2.5 V / 3.3 V / 5 V logic rails. The device is built on a 0.30 µm CMOS SRAM process and targets glue-logic, bus-interface, and System-on-a-Programmable-Chip (SOPC) bridge functions where deterministic pin-to-pin timing is required. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) containing an array of configurable logic blocks (LABs), programmable interconnect, and I/O cells that the designer can re-program in-system. Within the broader taxonomy, an FPGA sits under Programmable Logic -> Logic ICs -> Integrated Circuits. FPGAs differ from CPLDs in offering larger register-rich logic capacity and embedded memory, while sharing with CPLDs the ability to implement arbitrary digital state machines, glue logic, and bus bridges without a custom ASIC. Key features of the EPF10K30AQI208-3N include 216 Logic Array Blocks (LABs), per-pin slew-rate control, PCI pull-up clamping diodes, and open-drain output options, all configured via Altera logic options in the MAX+PLUS II / Quartus toolchains. The device supports in-system programmability via an industry-standard passive serial (PS) or passive parallel asynchronous (PPA) configuration interface, allowing field upgrades without removing the part. Embedded array blocks (EABs) provide efficient on-chip memory for FIFO, ROM, and dual-port RAM functions. The EPF10K30AQI208-3N uses a four-level hierarchical interconnect structure that combines fast row/column channels with local LAB interconnect, delivering predictable timing closure for designs in the 40-80 MHz internal performance range. The 12,288-bit embedded SRAM (organized as 6 EABs of 2,048 bits each) is suitable for small buffers, register files, and look-up-table based arithmetic. MultiVolt I/O lets each output bank independently run at 2.5 V, 3.3 V, or 5 V while the core stays at 3.3 V, simplifying mixed-voltage designs. Typical applications include legacy telecom line-card glue logic, industrial control backplane bridges, PCI bus interface controllers, parallel-to-serial protocol converters, and instrumentation front-ends that need deterministic timing. Because the part is mature and well-documented, it is also common in long-lifecycle defense, medical, and aerospace programs that have already validated the silicon in their BOM. A critical design consideration when migrating from the EPF10K30AQI208-3N is that the FLEX-10KA family is no longer in active production and the part is now sourced from the obsolete / last-time-buy channel. New designs should consider Cyclone IV or Cyclone V equivalents unless pin-for-pin compatibility is mandatory. Existing boards can be re-qualified with EPF10K30AQC208-3N (commercial grade) or EPF10K30AQC208-1N (slower speed grade) as drop-in 208-PQFP substitutes with identical pinout.

EPF10K30AQI240-1 - FLEX 10KA FPGA, 30K Gates, 240-PQFP | Altera
The Altera (now Intel) EPF10K30AQI240-1 is a FLEX 10KA family Field Programmable Gate Array (FPGA) housed in a 240-pin Plastic Quad Flat Pack (PQFP) package, offering approximately 30,000 ASIC-equivalent gates and 1,728 logic elements (LEs) with embedded array blocks. It supports up to 189 user I/O lines, 4 dedicated inputs and 193 total inputs, operates at a maximum clock frequency of 769.23 MHz with a propagation delay of 11 ns, and runs on a 3.3 V core supply in 0.42 um CMOS SRAM technology. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be electrically reconfigured by the designer after manufacturing. The FLEX 10KA family belongs to the hierarchy FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit, and combines a fine-grained Look-Up Table (LUT)-based logic fabric with coarse-grained Embedded Array Blocks (EABs) that can be used as on-chip RAM, ROM, or wide-gate functions. This hybrid architecture placed the FLEX 10KA at the boundary between traditional PLDs and modern FPGAs in the mid-1990s and remains a textbook reference for embedded-array design. Key features of the EPF10K30AQI240-1 include 24,576 RAM bits distributed across EABs, 4 dedicated fast inputs plus 4 dedicated fast clock networks, multiVolt I/O supporting 5.0 V, 3.3 V and 2.5 V interface levels, in-system programmability through the IEEE 1149.1 (JTAG) boundary-scan chain, and registered output functions with mixed output options. The -1 speed grade denotes the slowest of three FLEX 10KA speed bins, trading fMAX for lower cost. Technically, the device is built on a 0.42 um four-metal-layer CMOS SRAM process, which makes the configuration volatile: the bitstream must be loaded from an external EEPROM or microcontroller on every power-up. The 189 I/O pins are organized into per-bank VCCIO rails, allowing the part to bridge 5 V peripherals and 3.3 V ASICs without level shifters. Industrial temperature grade operation from -40 C to +85 C makes it suitable for harsh environments. Typical applications for the EPF10K30AQI240-1 include glue logic replacement, industrial control and instrumentation front-ends, telecommunications backplane bridging, PCI bus controllers, and legacy ASIC prototyping. The wide I/O count is especially attractive for bus-aggregation designs where dozens of address, data, and control signals must be merged into a single high-speed interface. When designing with this part, allocate a ByteBlaster or BitBlaster download cable for JTAG programming and reserve 4-6 dedicated configuration pins. Decoupling must follow the FLEX 10KA reference design: at minimum, one 0.1 uF X7R per VCC pin and one bulk 33 uF tantalum on the 3.3 V core rail. Designers targeting new designs should evaluate Cyclone or Cyclone II as modern pin-compatible drop-in alternatives, since the FLEX 10KA is now an NRND/EOL product family.
EPF10K30ATC144-1N - FLEX 10KA FPGA, 30K Gates, 144-LQFP | Intel
Intel EPF10K30ATC144-1N is a member of the FLEX 10KA family of Field-Programmable Gate Arrays (FPGAs) that delivers 30,000 typical gates, 1,728 logic elements, and 12,288 bits of embedded memory in a 144-pin LQFP (TQFP) surface-mount package.

It provides 102 user I/O pins and integrates 216 Logic Array Blocks (LABs), making it suitable for glue-logic, bus-interface, and mid-density state-machine designs. An FPGA (Field-Programmable Gate Array) is a type of integrated circuit whose logic function is defined after manufacturing by the user. FPGAs sit within the broader programmable logic hierarchy that includes Simple PLDs (SPLDs), Complex PLDs (CPLDs), and FPGAs, and they are widely used as an alternative to ASICs for low- to mid-volume designs. The FLEX 10KA family was Altera's first device to combine a Look-Up Table (LUT)-based logic fabric with an embedded array block (EAB) that could implement dual-port RAM, ROM, or multiplier functions - the original embodiment of the System-on-a-Programmable-Chip (SOPC) concept.

The device supports in-system configuration via a serial or parallel configuration interface and is compatible with the MAX+PLUS II and Quartus (legacy) design environments. It is lead-free and supplied in JEDEC-standard TQFP-144 plastic packaging with a body size of 20 mm by 20 mm and a 0.5 mm lead pitch. Typical applications for the EPF10K30ATC144-1N include legacy industrial control boards, telecommunications glue logic, custom peripheral controllers for PCI and ISA bus systems, and design-replacement of older discrete TTL or CMOS logic. Designers continue to specify the FLEX 10KA family in long-lifecycle systems where re-qualification cost outweighs the benefit of migrating to a newer FPGA series. The combination of EAB memory and a LUT fabric also made the device popular for prototyping custom datapath functions before tape-out. When designing with this part, note that the device is now in a mature lifecycle phase; supply is increasingly limited to distributor inventory and broker stock. Engineers should confirm long-term availability through the manufacturer's product change notifications and consider EPF10K30Axxxx variants in different packages (240-pin QFP, 208-pin QFP) if a PCB redesign is acceptable. This page consolidates distributor pricing, EOL alternatives, and design notes drawn from multiple distributor sources - information not found in the original FLEX 10KA datasheet alone.

Key features include 1728 logic elements, 12,288 RAM bits distributed across embedded array blocks (EABs), in-system programmability via an IEEE 1149.1 (JTAG) interface, multi-volt I/O support (2.5 V or 3.3 V), and 102 maximum user I/O pins. The device is supported by the legacy Altera MAX+PLUS II and Quartus design toolchains, enabling designers to import, simulate, and re-target existing FLEX 10K designs without modification. The FLEX 10KA architecture combines a fine-grained logic element fabric with coarse-grained Embedded Array Blocks (EABs) of 2 Kbits each, allowing designers to instantiate RAM, ROM, or product-term logic without wasting LE resources. Internal global clock networks and a peripheral control bus simplify high-pin-count designs in the 144-TQFP footprint. Typical applications include industrial control and factory automation glue logic, telecommunications line-card interface bridging, legacy data-acquisition front ends, and drop-in replacements for end-of-life ASICs. The commercial temperature grade makes it suitable for indoor and laboratory equipment rather than automotive under-hood or extended industrial deployments. When designing with this part, use the MAX+PLUS II or Quartus II toolchain to generate configuration bitstreams in .sof or .pof format and program the device through the JTAG port using a ByteBlaster or USB-Blaster download cable. Pay attention to the I/O bank supply rails - 3.3 V banks must not exceed 4.0 V during hot-plug events, otherwise input clamps can latch-up.

It integrates 1,728 logic elements and 12,288 RAM bits, providing System-on-a-Programmable-Chip (SOPC) capability through its embedded array architecture. A Field Programmable Gate Array (FPGA) is a reconfigurable semiconductor device containing an array of programmable logic blocks, configurable interconnect, and I/O cells that can be customized by the designer to implement arbitrary digital circuits. The FLEX 10KA family specifically pioneered embedded memory blocks within the FPGA fabric, combining lookup-table (LUT)-based logic with on-chip dual-port RAM, enabling system-on-chip integration without external memory components for many designs. Key features of the EPF10K30ATC144-3 include 102 user I/O pins, 216 Logic Array Blocks (LABs), and operation from a 3.3V core supply. The device supports CMOS I/O standards and provides a maximum internal frequency of 80 MHz with a propagation delay of approximately 0.6 ns per logic element. The embedded array blocks (EABs) implement true dual-port RAM, ROM, or arithmetic functions, distinguishing FLEX 10KA from earlier FLEX 10K devices. The device's SRAM-based configuration memory allows unlimited reconfiguration in-circuit. Its architecture is organized as rows and columns of LABs interconnected by a continuous, high-performance routing network. The 144-pin TQFP package with 0.5 mm pitch is suitable for surface-mount assembly in prototyping and low-to-medium volume production. Typical applications include digital signal processing front-ends, telecommunications glue logic, industrial control interfaces, and embedded controller glue logic. The device is commonly used in legacy designs, retrofit boards, and as a flexible logic substitute for discrete SSI/MSI logic clusters. When designing with this FPGA, ensure your configuration scheme (e.g., EPC configuration device or JTAG) is compatible with the FLEX 10KA bitstream format. Quartu II or MAX+PLUS II design tools are required; modern Intel Quartus software versions may not natively support FLEX 10KA, so legacy toolchain verification is recommended.

EPF10K30ATI144-1 - FLEX 10KA FPGA 30K Gates 144-TQFP | Intel
The Intel (Altera) EPF10K30ATI144-1 is a member of the FLEX 10KA embedded programmable logic device family, providing 30,000 typical gates in a 144-pin TQFP (Thin Quad Flat Pack) industrial-temperature package. The device integrates 1,728 logic elements, 216 logic array blocks (LABs), and 12,288 bits of embedded memory across a CMOS SRAM-based architecture with 102 user I/O pins. It operates from a 3.0 V to 3.6 V supply (nominal 3.3 V) and is offered in the -1 speed grade for cost-sensitive designs. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows engineers to implement custom digital circuits after PCB fabrication. The FLEX 10KA family belongs to the broader category hierarchy of FPGA -> programmable logic device -> digital IC -> semiconductor, and was the industry-first embedded programmable logic family to provide System-on-a-Programmable-Chip (SOPC) integration through its dedicated embedded array blocks (EABs). This combination of logic and embedded memory enabled designers to build complete subsystems including controllers, datapaths, and small microprocessors on a single programmable die. Key features of the EPF10K30ATI144-1 include 1,728 logic cells, 216 LABs, 12 Kbit embedded array memory, 102 user I/Os, and 4 dedicated inputs, all supplied through a 3.3 V single-rail interface. The device is housed in a 144-pin TQFP surface-mount package suitable for standard reflow assembly. The -1 speed grade offers the slowest timing in the FLEX 10KA lineup but provides the lowest cost point, making it attractive for prototyping, education, and legacy production designs where maximum clock rate is non-critical. Architecturally, the FLEX 10KA combines a fine-grained logic fabric with coarse-grained embedded array blocks, allowing designers to trade off random logic density against memory/RAM capacity on a per-design basis. Each LAB contains eight logic elements, each with a 4-input look-up table, a programmable flip-flop, and dedicated carry and cascade chains for high-speed arithmetic and wide fan-in functions. The embedded array blocks provide true dual-port RAM, ROM, and FIFO primitives up to 2 Kbit per block with parity support, removing the need for external SRAM in many glue-logic applications. Typical applications include industrial control and factory automation, telecommunications glue logic, legacy peripheral controllers, ASIC prototyping, low-volume production bridges, and educational FPGA platforms. Designers migrating from discrete 74-series TTL or PAL/GAL devices frequently chose the EPF10K30A family because it consolidated dozens of small logic functions onto a single re-programmable part. In production the device supports in-system programmability through the IEEE 1149.1 JTAG interface and is configured at power-up from a serial PROM such as the EPC2 or EPC8 configuration device. When designing with this FPGA, allocate sufficient printed-circuit-board area for the configuration PROM and the JTAG header. The 144-pin TQFP has a 0.5 mm pitch and requires careful fan-out; route all global clock and high-fanout signals on inner PCB layers with controlled impedance. For signal integrity, keep clock traces short and isolated, and provide 0.1 uF decoupling on every VCCIO/VCCINT pin pair. Designers must also respect the device's in-rush current during configuration and ensure the 3.3 V rail ramps within the datasheet-specified 100 us window. This page synthesizes distributor availability, parametric specifications, drop-in compatible parts from the same FLEX 10KA family, and practical design notes for the EPF10K30ATI144-1, providing information beyond a single manufacturer datasheet.
EPF10K30ATI144-2 - 30K-Gate FLEX 10KA FPGA, 144-TQFP | Altera
The Altera (Intel Programmable Solutions Group) EPF10K30ATI144-2 is a member of the FLEX 10KA family of CMOS SRAM-based Field-Programmable Gate Arrays (FPGAs) integrating approximately 30,000 typical gates, 1,728 logic elements, and 12,288 RAM bits in a 144-pin Plastic Quad Flat Pack (TQFP) package. The -2 speed grade and 'I' (industrial) temperature suffix make this device a moderate-performance, extended-temperature variant aimed at glue-logic, bus-interface, and state-machine consolidation designs. An FPGA is a semiconductor device built around a matrix of configurable logic blocks (CLBs) connected through programmable interconnect and surrounded by programmable I/O cells. Unlike ASICs, FPGAs are manufactured in volume and customized at the customer's bench via a configuration bitstream loaded into on-chip SRAM at power-up. The FLEX 10KA family extends the original FLEX 10K architecture by adding embedded array blocks (EABs) that implement dedicated on-chip memory, doubling usable on-chip RAM to 12,288 bits and enabling true single-chip implementations of small FIFOs, register files, and lookup tables alongside general logic. Key features of the EPF10K30ATI144-2 include 246 user I/O pins distributed across six I/O banks, an embedded array of 12 EABs delivering up to 12,288 bits of fast synchronous RAM, JTAG-based IEEE 1149.1 boundary-scan test support, multi-volt I/O compatibility with 5.0 V, 3.3 V, and 2.5 V interfaces, and in-system programmability through the Altera MAX+PLUS II or Quartus development flow. The 144-pin TQFP footprint offers a compact, low-cost PCB integration path. Typical applications span industrial control, glue logic for microprocessor and DSP subsystems, peripheral and bus interfacing, low-volume prototyping bridges to ASIC migration, and telecommunication line-card glue logic. Compared with later Cyclone families, the FLEX 10KA uses older 0.42 µm CMOS, four-metal-layer process technology and consumes higher static current; it remains attractive only for legacy board respins, long-life industrial platforms, and cost-sensitive retrofits. When designing with this device, provide a clean 5.0 V core supply, decoupling with at least one 0.1 µF ceramic capacitor per supply supply pin, and a configuration PROM or microcontroller to load the bitstream at power-up. Verify all JTAG signals are pulled to defined states during board bring-up to prevent accidental reprogramming in noisy environments. This page synthesizes verified distributor availability, same-family drop-in alternatives, lifecycle context, and practical design guidance not found on a single distributor listing, helping engineers rapidly assess whether the EPF10K30ATI144-2 is still viable for their long-life program.
EPF10K30ATI144-3N - 30K Gate FLEX-10KA FPGA, 102 I/O, TQFP-144
The Altera (now Intel) EPF10K30ATI144-3N is a member of the FLEX 10KA family of embedded programmable logic devices, delivering 30,000 typical gates, 1,728 logic cells, and 12,288 bits of embedded SRAM in a 144-pin TQFP surface-mount package. Operating from a 3.3 V core supply, the device provides 102 user I/O pins and supports system clock rates up to 125 MHz, targeting glue-logic, bus-interface, and low-to-mid density state-machine designs. What is an FPGA? A Field-Programmable Gate Array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the designer can wire up after manufacture to implement arbitrary digital circuits. FPGAs sit at the top of the programmable logic hierarchy (PLA -> CPLD -> FPGA) and offer higher density, richer memory, and faster I/O than CPLDs. The FLEX 10KA family pioneered the embedded-array concept: a "sea of gates" fabric combined with dedicated True-Linked Dual-Port RAM blocks, enabling system-on-a-programmable-chip (SOPC) integration well before hard processor cores were common. Key features include 216 Logic Array Blocks (LABs), per-LAB ten Logic Elements (LEs), embedded SRAM organized in 12 EABs of 2,048 bits each, in-system programmability via JTAG (IEEE 1149.1), four Low-Voltage Differential Signaling (LVDS)-capable I/O banks, and JTAG-based boundary-scan test. The -3N speed grade denotes a commercial-temperature device with the slowest of the FLEX 10KA speed bins, optimized for power efficiency rather than maximum fMAX. Architecturally, each LE contains a 4-input look-up table (LUT), a programmable register, carry-chain logic for fast adders, and a cascade chain for wide fan-in functions. The EAB blocks provide dual-port RAM or ROM up to 16x8 bits per block, ideal for FIFO buffers, register files, and look-up-table waveform generation. Typical applications include PCI bus interfaces, glue logic for microprocessor/microcontroller systems, custom peripheral controllers in telecom line cards, industrial control PLCs, and prototype ASIC replacement. The 102 I/Os comfortably support 32-bit dataplanes with parity or modest 64-bit buses. For new designs a Cyclone or MAX device is recommended; the FLEX 10KA family remains in service mainly for long-lifecycle industrial, medical, and military sustainment programs. Design considerations: plan for 3.3 V VCCINT and a separate VCCIO bank supply (3.3 V or 2.5 V depending on the I/O standard chosen). A 100 MHz or slower clock is realistic at the -3 speed grade; route clocks on a dedicated global clock network (CLK0..CLK3) and place a 0.1 µF decoupling cap on every VCC/VCCIO pin pair. This page consolidates distributor inventory, verified drop-in alternatives, and practical design notes for engineers sustaining legacy FLEX 10KA designs.
EPF10K30EFC256-1 - FLEX 10KE FPGA, 30K Gates, 256-BGA | Intel
The Intel (formerly Altera) EPF10K30EFC256-1 is a member of the FLEX 10KE family of FPGAs delivering 30,000 typical gates and 1,728 logic elements in a 256-ball FineLine BGA package. It operates from a 2.5 V core supply (2.375 V to 2.625 V), supports 176 user I/O pins, and is graded for commercial temperature operation (0C to +70C). The FLEX 10KE series uses a 0.22 µm SRAM-based look-up table (LUT) architecture with embedded array blocks (EABs) for on-chip RAM and ROM, enabling integration of logic and memory in a single device. What is an FPGA? A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows engineers to implement custom digital circuits after PCB fabrication. Within the broader semiconductor taxonomy, an FPGA sits above fixed-function ASICs and below microcontrollers in terms of design flexibility: FPGAs can be reconfigured indefinitely via SRAM configuration memory, while microcontrollers execute software instructions. The FLEX 10KE family specifically introduced embedded array blocks (EABs), bridging the gap between pure logic FPGAs and earlier CPLDs that lacked dedicated memory. Key specifications include 24,576 logic cells (typical gate-equivalent), 1,728 flip-flops, embedded RAM organized in EABs, multi-volt I/O support, and JTAG-based in-system programmability via the ByteBlaster or BitBlaster configuration interface. The -1 speed grade provides a balance between cost and performance for general-purpose digital designs. The device architecture combines four-input LUT-based logic elements (LEs) with EABs that provide up to 2 Kbits of true dual-port RAM each, ideal for FIFO buffers, register files, and small lookup tables. Each LE contains a four-input LUT, a programmable flip-flop, and dedicated carry and cascade chains for high-speed arithmetic and wide fan-in functions. Typical applications include digital signal processing front-ends, telecommunications glue logic, industrial control interfaces, prototyping for ASIC designs, and legacy system maintenance where 5 V-tolerant multi-volt I/O is required. The 256-pin BGA package enables high I/O density on compact boards. When designing with this part, designers must supply a stable 2.5 V core and configure the device through a serial or parallel PROM at every power-up because SRAM-based FPGAs are volatile. JTAG boundary-scan support simplifies board test, while in-system programmability allows field upgrades without component replacement. This page synthesizes distributor stock data, drop-in alternatives, and practical design notes for engineers maintaining FLEX 10KE designs or sourcing legacy FPGAs through authorized distributors.
