EP1K100QI208-2 - ACEX-1K 100K Gates FPGA, 208-PQFP | Intel / Altera
The Intel / Altera EP1K100QI208-2 is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs) providing 100,000 system gates, 4,992 logic elements (cells) and 49,152 bits of embedded RAM, housed in a 208-pin Plastic Quad Flat Pack (PQFP) package. It operates from a 2.5 V core supply with industrial-grade -40C to +85C temperature support and supports I/O banks that interface to 3.3 V and 5 V tolerant standards. The device is fabricated on a 0.22 umm CMOS SRAM process and targets low-cost system-on-a-programmable-chip (SOPC) integration. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnect, and embedded memory blocks that can be re-programmed to implement any digital logic function. FPGAs occupy the programmable-logic tier of the broader digital IC hierarchy: gate array < FPGA < CPLD < programmable SoC. Compared to ASICs, FPGAs deliver lower NRE cost and faster time-to-market but trade off raw clock speed and per-unit cost. The ACEX-1K family is positioned for high-volume, cost-sensitive glue logic, bus bridging, and DSP preprocessing in industrial and telecom equipment. Key features include 624 Logic Array Blocks (LABs), 147 user I/Os, dual-port embedded array blocks (EABs) that can be configured as RAM, ROM, or FIFO, and four low-skew global clock networks. Maximum toggle performance is rated around 250 MHz, with on-chip phase-locked loops (PLLs) for clock synthesis. The 208-pin PQFP (also referenced as BFQFP / QFP-208) package provides a 0.5 mm pitch suitable for conventional SMT assembly lines. The EP1K100QI208-2 is configured through the Altera Quartus design suite (legacy: MAX+PLUS II). Boundary-scan (IEEE 1149.1 JTAG) is supported, and the device is in-system programmable via JTAG or configuration devices such as the EPC2. Application domains include industrial control, telecom interface cards, glue logic for embedded processors, and legacy glue logic replacements for 5V-tolerant 74-series designs. When designing with this part, ensure 2.5 V core decoupling with 0.1 uF ceramic capacitors placed as close to each VCCINT pin as possible, separate VCCIO rails per bank, and use of the Altera configuration device for stand-alone boot. The device is NRND/last-time-buy in many channels - confirm lifecycle before new designs.
EP1K100QI208-2N - ACEX-1K FPGA, 4992 LE, 147 I/O | Altera
The Intel/Altera EP1K100QI208-2N is an ACEX-1K Field Programmable Gate Array (FPGA) with 4,992 logic elements, 49,152 RAM bits, and 147 user I/Os, supplied in a 208-pin BFQFP surface-mount package. It is the Pb-free (N), industrial-temperature (-I) variant with a -2 speed grade, making it a compact, mid-density programmable logic device for legacy embedded systems. An FPGA is a semiconductor device containing programmable logic blocks and programmable interconnects that can be configured after manufacturing to implement arbitrary digital logic. FPGAs sit above CPLDs in logic capacity and are widely used where ASIC development cost is prohibitive, or where in-field logic updates are needed. In the programmable logic hierarchy, this ACEX-1K device belongs to the Altera FPGA family, from the older high-density programmable logic product class that also includes MAX, FLEX, and Cyclone families. Key features confirmed by the DigiKey and Mouser listings include 4,992 logic elements arranged in 624 LABs, 49,152 total RAM bits, 147 user I/Os, and a 208-BFQFP package. The industrial temperature option and Pb-free finish make the EP1K100QI208-2N attractive for extended-temperature legacy boards that must still meet modern lead-free assembly rules. The ACEX-1K family is a 2.5 V core FPGA solution and provides embedded memory blocks for FIFOs, distributed RAM, and ROM functions. The EP1K100 architecture uses a look-up-table-based logic element fabric with fast carry chains, plus dedicated embedded array blocks for memory-rich designs. The -2 speed grade is a mid-range performance option; faster -1 and slower -3 grades exist in the same package, allowing board-level speed migration without changing the PCB footprint. The 208-pin BFQFP package provides enough I/Os for local bus interfaces, memory controllers, and moderate parallel processing tasks while simplifying manufacturing compared with fine-pitch BGA packages used by larger ACEX devices. Typical uses include industrial control I/O boards, video/imaging preprocessing, communication interface bridging, test instruments, and system power-management sequencing logic. Because the device can be reconfigured, it is also suitable for prototyping glue logic in mixed-signal designs. When designing with the EP1K100QI208-2N, remember to place a configuration device or download cable header close to the FPGA and reserve enough board area for the 2.5 V core regulator and I/O bank supplies. Board-level pin migration between -1, -2, and -3 speed grades in the same 208-pin package is possible, but always verify the exact configuration bitstream and timing closure after changing speed grade. This page synthesizes distributor availability, verified datasheet links, drop-in same-family alternatives, and practical design notes not found in a single component listing. It is intended for engineers evaluating legacy Altera FPGA replacements, spare-part sourcing, and PCB pin-compatible upgrades.
EP1K100QI208-3 - 100K Gates ACEX 1K FPGA, 208-PQFP | Altera
The Altera EP1K100QI208-3 is a member of the FLEX 10K / ACEX 1K family of CMOS Field Programmable Gate Arrays, delivering approximately 100,000 gates organized as 4,992 logic cells across 624 Configurable Logic Blocks (CLBs). Housed in a 208-pin Power Quad Flat Pack (PQFP / QFP, gull-wing) package, the device provides 147 general-purpose user I/O pins plus 6 dedicated inputs, targeting high-performance logic, glue-logic, and DSP datapath applications. It is built on a 2.5 V nominal core supply (max 2.625 V) and operates over the industrial temperature range of -40 °C to +85 °C. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines an array of configurable logic blocks, programmable interconnect, and I/O cells on a single CMOS die. The ACEX 1K family sits in the hierarchy: programmable logic device -> CPLD/FPGA -> SRAM-based FPGA -> ACEX 1K, representing one of the early low-cost, high-volume SRAM-lookup-table FPGA families from Altera (later acquired by Intel). Each logic element uses a 4-input LUT plus a register, and the embedded array blocks (EABs) can be configured as RAM, ROM, or multiplier primitives, allowing designers to mix datapath and control logic without external memory. Key features include 4,992 logic cells / 624 CLBs, ~100 K system gates, 147 user I/Os, an embedded array block memory architecture, JTAG-based IEEE 1149.1 boundary-scan support, and an SRAM-based configuration cell that loads from a serial or parallel EPROM. The "-3" speed grade corresponds to the fastest commercial timing bin offered for this device family, enabling higher fMAX on internal logic and shorter pin-to-pin tPD delays than the slower -1 or -2 grades. The PQFP-208 package has a thermal resistance suitable for forced-air or large-copper PCB designs commonly used in telecom and industrial control chassis. Typical applications include telecommunications line-card glue logic, industrial motor-control state machines, ASIC prototyping, DSP pre/post-processing pipelines, and legacy PCI/ISA bus-interface bridges where the 5 V-tolerant I/O and rich register fabric are advantageous. Designers often pair the EP1K100QI208-3 with an EPC2 configuration device to store the bitstream. When designing with this part, ensure the JTAG chain is correctly ordered with any downstream devices, since multi-device scan chains are a common source of configuration failures. Verify the configuration mode (AS, PS, or JTAG) matches the EPC2 / EPC4 selected, and never apply VCC before the configuration device is stable.
EP1K100QI208-3N - ACEX 1K FPGA, 4992 LE, 2.5V | Intel
The Altera EP1K100QI208-3N is an ACEX 1K family CMOS field-programmable gate array (FPGA) with 4992 logic elements, 49152 total RAM bits, and 147 user I/O pins, delivered in a 208-pin QFP (BFQFP) package and rated for industrial -40C to +85C operation on a 2.5V nominal core supply. An FPGA is a digital integrated circuit whose logic fabric and routing are configured after manufacturing by loading a bitstream, allowing designers to implement custom state machines, bus interfaces, and parallel processing without committing to a fixed ASIC. This EP1K100 device sits between small CPLDs and larger million-gate FPGAs in the programmable-logic hierarchy: its embedded RAM array can be used as FIFOs or small buffers, while the 4992 logic elements provide moderate-density user logic on a single surface-mount QFP. Key features of the EP1K100QI208-3N include the 2.5V ACEX 1K core architecture, 147 general-purpose I/O pins plus 6 dedicated input pins, 49152 RAM bits, and the industrial QI temperature option. The 208-pin gull-wing QFP package supports conventional SMT assembly without the expensive board technology needed by BGA devices, and the -3 speed grade provides a balanced mainstream operating-frequency range for industrial designs. From a technical standpoint, the EP1K100QI208-3N uses SRAM-based configuration, which means it must be configured at power-up by a configuration device or host processor. The I/O count and embedded memory make it suitable for applications that need parallel bus control, display interfaces, or multiple communication channels while still preserving routing flexibility. Because the family is no longer in active production, designers should confirm the exact speed grade, temperature suffix, and lead-free order code on the original Altera/Intel ordering table before committing to production. Typical applications include industrial control I/O boards, test and measurement front-end logic, telecommunication line-card control, image-related frame buffering, and moderate-throughput data path processing. The -40C to +85C industrial rating allows the device to be placed in unheated cabinets, outdoor telecom enclosures, and factory-floor equipment without exceeding the guaranteed temperature specification. One important design consideration is that this is a 2.5V-core FPGA, so 5V or 3.3V external devices require level-shifting and careful I/O standard planning. Supply decoupling should be placed close to every VCC pin, and the configuration source must be selected so that the FPGA reliably loads its bitstream during power-up. This page synthesizes distributor price signals, drop-in alternatives, and practical design notes for the EP1K100QI208-3N beyond what is typically found in a raw datasheet listing, helping engineers evaluate sourcing and replacement options quickly.
EP1K10FC256-1 - 10K Gates ACEX-1K FPGA, 256-BGA | Intel
The Intel (formerly Altera) EP1K10FC256-1 is an ACEX-1K family Field-Programmable Gate Array (FPGA) with 10,000 typical gates, 576 logic elements, 12,288 RAM bits, and 136 user I/Os, housed in a 256-ball FineLine BGA (FBGA-256) package. Built on a 0.22 µm CMOS SRAM-lookup-table process, it operates from a 2.5 V core supply and supports in-system programmability via IEEE 1149.1 JTAG and Altera EPC configuration devices. The "-1" speed grade corresponds to a -1 internal performance tier with up to 250 MHz internal operation, and "FC" denotes a commercial-temperature plastic BGA. What is an FPGA? An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) containing an array of configurable logic blocks (CLBs), embedded memory blocks, and programmable interconnect. FPGAs sit at the top of the programmable logic hierarchy below ASICs and above simple PLDs/CPLDs, enabling designers to implement custom digital logic, glue logic, state machines, bus interfaces, DSP pipelines, and even soft-processor cores after PCB assembly. Unlike an ASIC, an FPGA is reconfigurable in the field, which shortens design cycles and supports design iteration. The ACEX-1K family is Altera's mid-density, low-cost CPLD/FPGA crossover family from the early 2000s, designed for glue-logic and low-density glue / bus-interface applications. Key features of the EP1K10FC256-1 include 576 logic elements (12 LEs per LAB array), 12 kbit embedded SRAM (EAB blocks), 136 maximum user I/Os, 3.3 V/2.5 V LVTTL/LVCMOS-compatible I/O with multi-voltage support, and an embedded array block (EAB) for memory or product-term logic. Its SRAM-based configuration requires a boot PROM (typically EPC2) or JTAG download. The 256-ball FineLine BGA (1.0 mm pitch) enables high I/O count in a compact footprint. Typical applications include glue logic replacement, bus-interface bridging (e.g., PCI-to-local bus), low-density DSP preprocessing, parallel I/O expansion, and industrial control interface cards. The 136 user I/Os make it well suited to interfacing with parallel SRAM, FIFOs, and legacy microcontrollers. The 2.5 V core is compatible with 3.3 V I/O banks, allowing mixed-voltage system integration. A critical design consideration is that ACEX-1K is now NRND/last-time-buy; new designs should consider Cyclone series. The SRAM configuration must be reloaded on every power-up. The 256-BGA requires X-ray or rework-grade assembly for prototyping. Decoupling per Altera ACEX-1K handbook recommended 0.1 µF per VCC pin and bulk 33 µF tantalum.
EP1K10FC256-2 - 10K ACEX-1K FPGA, 136 I/O, 256-BGA | Intel / Altera
The Intel / Altera EP1K10FC256-2 is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs) housed in a 256-ball FineLine BGA package with 136 user I/O pins. The device integrates 576 logic elements organized as 72 Logic Array Blocks (LABs), supported by 12,288 RAM bits of embedded dual-port memory and approximately 10,000 typical gates. It is fabricated on a 0.22 µm CMOS process and operates from a 2.5 V core supply within the 2.375 V to 2.625 V tolerance band. An FPGA (Field Programmable Gate Array) is a class of programmable logic device (PLD) that combines the density of gate arrays with the configurability of logic blocks, interconnect, and I/O. Within the broader system-on-a-programmable-chip (SOPC) taxonomy, FPGAs enable integration of megafunctions such as DSP blocks, FIFOs, dual-port memories, and specialized logic into a single device, replacing multiple discrete components and accelerating time-to-market. Key features of the EP1K10FC256-2 include a maximum toggle frequency around 200 MHz, embedded array blocks (EABs) for efficient memory and specialized logic functions, support for LVCMOS, LVTTL, SSTL-2/3, and HSTL I/O standards, and an in-system programmability (ISP) interface via the JTAG-compliant passive serial configuration scheme. The device is specified for commercial operating temperature (0 °C to 70 °C) at the -2 speed grade. From a technical depth perspective, the ACEX-1K architecture pairs a fine-grained Look-Up Table (LUT)-based logic fabric with coarse-grained Embedded Array Blocks (EABs) that can be configured as RAM, ROM, or specialized megafunction blocks. This heterogeneous structure delivers higher effective logic density than uniform LUT fabrics of similar raw gate count, while the 0.22 µm process balances cost and performance for cost-sensitive glue-logic, bridging, and control-plane applications. Typical applications include telecommunications bridging, low-density glue logic, industrial control interfacing, and pre-silicon prototyping of ASIC-equivalent logic. With its small footprint, ample dual-port memory, and JTAG ISP, the EP1K10FC256-2 is widely used in legacy designs where re-spin cost or supply continuity matter more than absolute logic density. When designing with this part, verify that the Quartus II or MAX+PLUS II toolchain supports the ACEX-1K family, confirm power-rail sequencing for the 2.5 V VCCINT and any bank reference voltages, and respect the device's I/O pin count when migrating from the original -1 or -3 speed grades. This page synthesizes distributor pricing, drop-in same-package alternatives, application contexts, and practical design notes not found in the original Altera datasheet alone.
EP1K10FC256-2N - 10K Gate ACEX-1K FPGA 576 LE 256-BGA | Intel / Altera
The Intel / Altera EP1K10FC256-2N is a member of the ACEX-1K family of Field-Programmable Gate Arrays (FPGAs) built on a 2.5 V SRAM-based look-up table (LUT) architecture, offering 10,000 typical gates, 576 logic elements, and 12,288 RAM bits in a 256-ball FineLine BGA package. It integrates an enhanced embedded array for megafunctions such as efficient memory and specialized logic, with dual-port RAM and 72 Logic Array Blocks (LABs) supporting up to 136 user I/O pins. What is a FPGA? A Field-Programmable Gate Array is a semiconductor device based around a matrix of configurable logic blocks (CLBs) connected via programmable interconnect. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs) -> complex programmable logic devices (CPLDs) -> FPGAs -> high-density SRAM-based FPGAs. Unlike fixed-function ASICs, FPGAs can be reconfigured in-system to implement custom digital logic, glue logic, signal processing pipelines, and bus interfaces, making them ideal for prototyping and low-to-mid volume production. Key features of the EP1K10FC256-2N include 0.5 ns pin-to-pin logic delay, built-in dual-port RAM, support for the Altera MAX+PLUS II and Quartus design flows, and a 2.375 V to 2.625 V core supply. The 256-ball FineLine BGA package provides high I/O density for memory-rich and bus-interface designs, while the commercial 0 °C to 70 °C operating range suits bench instrumentation, communications glue logic, and industrial control boards. The ACEX-1K architecture uses an embedded array of Enhanced Logic Elements (ELEs) interleaved with embedded array blocks (EABs) that implement dedicated dual-port RAM and ROM. This hybrid fabric lets designers place megafunctions such as FIFOs, CAMs, multipliers, and DSP blocks in silicon-efficient EABs while reserving LUTs for random logic, yielding better performance-per-area than pure 4-input LUT FPGAs of the same era. Typical applications include glue logic for legacy microprocessor buses, peripheral controllers (UART, SPI, I2C bridges), low-speed digital signal processing front-ends, prototyping platforms, and industrial communication bridges. The 136 available user I/Os also make the EP1K10FC256-2N a practical fit for memory-interface bridging, where the 12 Kbits of embedded RAM act as a small cache or FIFO between two clock domains. When designing with this device, plan power sequencing carefully because the 2.5 V core must ramp monotonically while I/O banks can be powered at 3.3 V to remain LVTTL/LVCMOS-compatible. Decoupling requires 0.1 µF high-frequency capacitors placed within 5 mm of every supply pin, plus bulk capacitance on each supply plane to manage in-rush during configuration. This page synthesizes distributor pricing, drop-in ACEX-1K family alternatives, and practical design notes not found in the original manufacturer datasheet.
EP1K10FC256-3 - ACEX 1K FPGA, 10K Gates, 256-BGA | Intel
The Intel (formerly Altera) EP1K10FC256-3 is a member of the ACEX 1K family of Field-Programmable Gate Arrays (FPGAs), featuring 10,000 typical gates, 576 logic elements, and 12,288 RAM bits in a 256-ball Fine-Pitch Ball Grid Array (FBGA) package with 136 user I/Os. Operating from a 2.5 V core supply, it is built on a 0.18 µm SRAM-based architecture with embedded array blocks optimized for cost-sensitive, high-volume designs. A FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that combines the density of gate arrays with the flexibility of user-programmable interconnect, enabling designers to implement custom digital logic, glue logic, glue-less interfaces, state machines, and arithmetic pipelines on a single chip. Within the broader taxonomy of integrated circuits, an FPGA sits between standard logic ICs (fixed function) and ASICs (application-specific) - offering hardware-level parallelism and re-programmability without NRE costs. Key features of the EP1K10FC256-3 include 72 logic array blocks (LABs), dual-port EAB (Embedded Array Block) memory, in-system programmability via IEEE 1149.1 JTAG, MultiVolt I/O support for interfacing with 2.5 V, 3.3 V, and 5.0 V systems, and a -3 speed grade. The device supports 12,288 bits of embedded RAM distributed across EAB blocks, enabling efficient on-chip buffering for FIFOs, lookup tables, and small data paths without consuming general-purpose logic. The ACEX 1K architecture combines logic elements (LEs) with embedded array blocks (EABs), where each EAB provides up to 4 Kbits of RAM that can be configured as synchronous SRAM, ROM, or specialized logic functions such as multipliers and megafunctions. The -3 speed grade designates a mid-tier performance bin, balancing timing margin against cost for glue logic, bus bridging, and low-to-mid complexity state machines rather than high-speed DSP or SERDES workloads. Typical applications include bus-interface bridging between microcontrollers and peripherals, glue logic replacement in telecom and industrial control equipment, low-density control and signal processing in test and measurement, and prototyping platforms for ASIC verification. Its dual-port EAB structure also makes it well suited to small FIFO buffers and lookup-table-based waveform synthesis. When designing with this part, pay attention to the 256-ball FBGA land pattern, the 2.5 V VCCINT/VCCIO rail requirements, and the JTAG chain integration with any boundary-scan test infrastructure. Engineers migrating from the original ACEX 1K family should also evaluate the Cyclone-series successors for new designs, while keeping the EP1K10FC256-3 as a long-term production component for legacy boards.

EP1K10FC256-3N - 10K Gates ACEX-1K FPGA, 256-FBGA | Intel / Altera
The Intel (formerly Altera) EP1K10FC256-3N is an ACEX-1K family Field Programmable Gate Array (FPGA) delivering 10,000 typical gates and 576 logic elements in a 256-ball FineLine BGA package with 136 user I/O pins, operating from a 2.5 V core supply on a 0.22 µm CMOS process. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs / LABs) interconnected by a programmable routing fabric. FPGAs sit in the programmable logic hierarchy below ASICs (Application-Specific ICs) but above discrete glue logic, offering hardware-level parallelism, in-field reprogrammability, and time-to-market advantages. The ACEX-1K family, introduced by Altera in the late 1990s, was an early "system-on-a-programmable-chip" (SOPC) family that embedded array blocks (EABs) alongside logic to deliver efficient memory and DSP megafunctions in a single device. Key features of the EP1K10FC256-3N include 72 LABs (Logic Array Blocks), 12288 bits of embedded RAM (12 Kbits), 136 user I/O pins, a maximum internal operating frequency around 200 MHz, and SRAM-based configuration cells requiring an external configuration device or JTAG. The "-3" speed grade and "N" suffix denote a commercial-temperature, lead-free, lead-free reflow-compatible process. The 256-FBGA (17 mm × 17 mm) package is a surface-mount fine-pitch BGA designed for high-density board layouts. Architecturally, the EP1K10FC256-3N combines 72 LABs (each with 8 logic elements) and embedded array blocks (EABs) used as dual-port or single-port RAM, ROM, or multiplier megafunctions. Configuration is SRAM-based, meaning the device loses its bitstream at power-down and must be reconfigured at boot from an external PROM, JTAG, or controller - a critical design consideration that distinguishes ACEX-1K from later Cyclone/MAX-based flash- or antifuse-based families. Typical applications include glue-logic integration, custom interface bridging (PCI, I2C, UART), low-to-moderate complexity DSP pre/post-processing, industrial control and instrumentation, and legacy telecommunications line cards. ACEX-1K parts were also widely used in development boards, prototyping platforms, and educational FPGA labs. When designing with the EP1K10FC256-3N, ensure an external configuration source (EPC1/EPC2 serial PROM, ByteBlaster, or JTAG) is in the BOM - the part is volatile and will not retain its design on power-cycle. Verify the 2.5 V core supply decoupling network: at least four 0.1 µF ceramic capacitors plus a bulk 47-100 µF tantalum placed within 25 mm of the FBGA supply balls is recommended. This page synthesizes distributor pricing, same-package drop-in alternatives from the same ACEX-1K family, configuration-device recommendations, and practical design notes not consolidated on any single distributor page.
EP1K10FI256-2 - 10K Gates ACEX-1K FPGA, 256-BGA | Altera
The Intel (formerly Altera) EP1K10FI256-2 is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs) integrating 10,000 equivalent gates, 576 logic cells (LEs) organized into 72 Configurable Logic Blocks (CLBs), 12,288 bits of embedded array RAM (EAB), and 136 maximum user I/O pins, all housed in a 256-pin FineLine BGA (FBGA) package. The "-2" speed grade denotes the standard speed bin, and the part is built on a 0.22 µm CMOS process with a 2.5 V core supply, targeting low-cost system-on-a-programmable-chip (SOPC) integration. A Field-Programmable Gate Array (FPGA) is a reconfigurable digital integrated circuit that combines programmable logic blocks, programmable interconnects, and programmable I/O cells on a single die. Within the broader taxonomy, an FPGA belongs to programmable logic devices (PLD) -> digital logic IC -> semiconductor. ACEX-1K specifically implements an enhanced embedded array architecture that enables efficient megafunctions such as dual-port RAM, ROM, and specialized DSP blocks while keeping per-unit cost comparable to mid-range ASICs. Key features of the EP1K10FI256-2 include a maximum internal operating frequency of 200 MHz, in-system programmability via IEEE 1149.1 (JTAG) and passive serial configuration modes, multi-voltage I/O support (1.8 V, 2.5 V, 3.3 V LVTTL/LVCMOS), and a 4-input look-up table (LUT) structure per logic element. The device is offered in the industrial temperature grade (-40 °C to +85 °C) per the "I" suffix in the package code, making it suitable for factory, automotive, and outdoor edge nodes. Architecturally, ACEX-1K devices use a continuous SRAM-based configuration cell so designs can be reloaded at any time without removing the part from the board, which is critical for field upgrades and prototyping workflows. The 256-ball FineLine BGA package provides high-density board escape, and the part is supported by the Quartus development toolchain (legacy: MAX+PLUS II). Engineers typically use the EP1K10FI256-2 for glue logic, custom interface bridging, and pre-ASIC prototyping of low-to-medium complexity state machines. Typical applications for this part include industrial control glue logic, telecom line-card glue and interface bridging, custom peripheral controllers in PCI/ISA systems, low-density DSP co-processors, and pre-ASIC prototyping of mid-range ASICs. The 256-BGA footprint is widely reused, allowing board layouts to be ported across the ACEX-1K density range from EP1K10 up to EP1K100. When designing with the EP1K10FI256-2, ensure that the 256-ball FBGA land pattern is correct (1.0 mm pitch FineLine BGA) and that PCB routing accounts for the finer escape. Decoupling must include at least four 0.1 µF capacitors placed within 5 mm of the VCCINT/VCCIO power balls, plus a 10 µF bulk capacitor per power rail. JTAG signals (TCK, TMS, TDI, TDO) must be pulled to a defined logic level through 10 kΩ resistors to keep configuration mode stable at power-up.

EP1K10FI256-2N - 10K Gates ACEX 1K FPGA 256-FBGA | Intel
The Intel (formerly Altera) EP1K10FI256-2N is a member of the ACEX 1K family of Field Programmable Gate Arrays (FPGAs) featuring 10,000 typical gates, 576 logic elements (cells), and 12,288 RAM bits in a 256-ball FineLine BGA package. Built on a 0.22 µm CMOS process with a 2.5 V core supply and industrial temperature grade, this device targets low-cost system-on-a-programmable-chip (SOPC) integration through its enhanced embedded array architecture. The -2 speed grade delivers up to 200 MHz internal operation, making it suitable for glue logic, bus interface bridging, and DSP co-processing applications. What is an FPGA? A Field Programmable Gate Array is a semiconductor device built around an array of configurable logic blocks (CLBs) connected by programmable interconnect, surrounded by programmable I/O cells. FPGAs sit at the top of the programmable logic hierarchy: programmable logic device (PLD) -> complex PLD (CPLD) -> FPGA -> SoC FPGA. Unlike CPLDs which use non-volatile fuse/flash memory and are best for combinatorial glue logic, FPGAs are RAM-based and contain dedicated memory blocks, multiplier blocks, and high-speed I/O serializers, making them appropriate for data-path, DSP, and pipelined designs. The ACEX 1K architecture combines a continuous Embedded Array (EAB-based dual-port memory), Logic Array (LUT-based logic), and enhanced I/O elements with JTAG boundary-scan support. Each EAB provides dual-port RAM up to 4 Kbits and can be configured for FIFO, ROM, or single-port memory. The 136 user I/O pins support multiple I/O standards (LVTTL, LVCMOS, PCI) with 5 V tolerance on selected banks. Configuration is via passive serial (PS), active serial (AS), or JTAG modes using a serial configuration device. This device is a drop-in upgrade path for Altera FLEX 8000/10K designs requiring higher density or faster speed grades, while remaining software-compatible with the MAX+PLUS II and Quartus design tools (legacy support). Typical applications span industrial control, telecommunications line cards, automotive telematics, and instrumentation data acquisition. The 256-ball 1.0 mm pitch FBGA package enables compact board layouts while providing 136 usable I/O pins for high pin-count designs. When designing with this FPGA, plan configuration memory on a serial EEPROM or via JTAG for in-system reprogrammability. The 2.5 V core requires a low-dropout regulator with adequate decoupling; place 0.1 µF ceramic capacitors adjacent to each VCCINT ball. Industrial temperature grade (-40 °C to +85 °C) allows deployment in uncontrolled environments. Note that ACEX 1K is a legacy family — verify long-term supply via Intel/Altera product longevity commitments before committing to new designs. This page synthesizes distributor pricing, drop-in alternative listings, and engineering design notes not found in the original ACEX 1K datasheet, with cross-references to other ACEX 1K speed and temperature variants for migration planning.
EP1K10QC208-1N FPGA - ACEX 1K 10K Gates 2.5V | Altera
The Altera EP1K10QC208-1N is a 2.5 V ACEX-1K field-programmable gate array (FPGA) that implements approximately 10,000 typical gates with 576 logic elements, 72 LABs, 120 user I/O pins, and 12,288 RAM bits in a 208-pin BFQFP (PQFP-208) package. It is a -1 speed grade device with a listed maximum internal frequency of 250 MHz and is manufactured with 0.22 um CMOS technology. An FPGA is an integrated circuit whose logic fabric can be reconfigured after manufacturing by loading a hardware description. Unlike fixed-function ASICs, FPGAs contain programmable logic elements, I/O cells, and interconnect; designers use HDL to describe logic, then place and route the design into the programmable fabric. The ACEX-1K family was Altera's low-cost 2.5 V FPGA line, positioned between CPLDs and larger FPGA families. This hierarchy matters because engineers selecting EP1K10QC208-1N are usually choosing programmable logic rather than a fixed microcontroller or ASIC. The EP1K10QC208-1N contains 576 logic elements arranged in 72 LABs, providing enough logic for state machines, bus interfaces, decode logic, and small data-path operations. It provides 120 user I/O pins and 12,288 embedded RAM bits, making it useful for glue logic consolidation, FIFO buffers, and parallel interface adaptation. The lead-free N suffix distinguishes this version for modern RoHS-oriented assembly lines. The package is a square, surface-mount 208-pin metal/bump quad flat pack with gull-wing terminals, known in the industry as PQFP-208 or BFQFP. The core runs at 2.5 V, consistent with Altera's 0.22 um process generation. In a typical design, the FPGA core consumes modest static power; dynamic power scales with toggle rate, IO loading, and resource utilization. The 250 MHz speed grade listed in family specifications is a maximum internal switching-frequency rating, not a guaranteed system clock for all routed designs. Actual timing closure depends on routing delays, placement, fan-out, and the use of global clock resources. Typical applications include industrial interface boards, motor-control logic, display timing generation, communication protocol adapters, and digital system prototyping. With 120 I/O and 10K typical gates, the device fits designs that require parallel control or simple DSP, and it can replace obsolete ASICs when an FPGA bitstream is acceptable. In retrofit scenarios, the -1N lead-free option is useful for new PCB assembly lines that require lead-free solder. A key design consideration is configuration: this FPGA is volatile and needs an external configuration source such as a CPLD, configuration device, or controller. Designers should plan for configuration time and use the appropriate JTAG or passive serial interface on power-up. This page synthesizes distributor listing data, speed-grade alternatives, pricing context, and practical FPGA design guidance that is not all contained in a single datasheet view, giving engineers a useful starting point for sourcing and replacement decisions.
EP1K10QC208-2 - ACEX-1K FPGA, 10K Gates, 576 Logic Elements, 208-PQFP | Intel (Altera)
The Intel (formerly Altera) EP1K10QC208-2 is a member of the ACEX-1K family of Field-Programmable Gate Arrays (FPGAs), delivering 10,000 equivalent system gates, 576 logic elements arranged as 72 Configurable Logic Blocks (CLBs), and 12,288 RAM bits of dual-port embedded memory, all integrated in a 208-pin Plastic Quad Flat Pack (PQFP / BQFP) package. Built on a 2.5 V CMOS process, the -2 speed grade part is specified for commercial operating conditions and supports 120 user I/O pins, enabling compact integration of glue logic, register-transfer designs, and modest DSP pipelines on a single programmable device. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the user can re-program in-system to implement arbitrary digital functions. FPGAs sit between fixed-function ASICs and microcontrollers: more flexible than ASICs (no mask set, no NRE) and faster/higher-throughput than microcontroller firmware. ACEX-1K sits in the low-density end of the historical Altera product tree: FPGA family > SRAM-based FPGA > low-cost programmable logic > system-on-a-programmable-chip (SOPC) building block. Key features include on-chip dual-port RAM for FIFO and register-file implementation, embedded array blocks (EABs) for memory-mapped functions, JTAG-based IEEE 1149.1 boundary-scan test support, and dedicated routing resources that preserve timing margins at the -2 speed grade. The 208-BQFP package is a through-hole-compatible gull-wing surface-mount outline, enabling PCB layouts that have been in continuous service in industrial controllers, telecom line cards, and test equipment for two decades. Typical applications include industrial control and factory automation backplanes, telecom line-interface glue logic, legacy test-and-measurement instrumentation, and migration of older discrete-TTL designs onto a single reconfigurable device. The ACEX-1K family uses SRAM configuration cells, so a configuration PROM (EPC1, EPC2) or a microcontroller-driven download cable is required to load the bitstream at every power-up. When designing with this part, verify that your Quartus II design flow targets the ACEX-1K device family explicitly; newer Quartus versions do not include the legacy ACEX-1K libraries, so an older release or a third-party toolchain may be required. Plan for the configuration memory requirement: an 8-bit-wide EPC2 or compatible serial PROM is the standard storage device for production boards.
EP1K10QC208-2N - ACEX-1K 10K Gates FPGA | Intel / Altera
The Intel (formerly Altera) EP1K10QC208-2N is a member of the ACEX-1K family of SRAM-based Field Programmable Gate Arrays (FPGAs), delivering 10,000 typical gates, 576 logic elements, and 12,288 bits of embedded array RAM in a 208-pin plastic Quad Flat Pack (PQFP/BFQFP) package. It operates from a 2.5V core supply (2.375V to 2.625V) and provides 120 user I/O pins, making it suitable for medium-density glue-logic, bus-interface, and control-plane applications. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs), programmable interconnect, and programmable I/O cells. FPGAs belong to the broader category of programmable logic devices (PLDs), which also include SPLDs, CPLDs, and structured-ASIC-class devices; within the semiconductor hierarchy they sit between fixed-function ASICs and general-purpose processors, offering hardware-timed parallelism with field-updatable functionality. The ACEX-1K family introduced embedded array blocks (EABs) that can be configured as dual-port RAM, ROM, or first-in-first-out (FIFO) memory, giving it a hybrid PLA + memory architecture uncommon to its generation. Key features of the EP1K10QC208-2N include 576 logic elements organized into 72 logic array blocks (LABs), 12 embedded array blocks providing up to 24 Kbits of RAM, IEEE 1149.1 JTAG boundary-scan support, multi-volt I/O compatible with 2.5V/3.3V/5.0V mixed-voltage buses, and in-system programmability via the Altera serial configuration (AS) or passive serial (PS) modes. The device is fabricated on a 0.22 µm CMOS process and supports commercial temperature grades. Architecturally, the EP1K10QC208-2N combines a fine-grained logic fabric with coarse-grained EAB memory, allowing designers to implement megafunctions such as multipliers, FIR filters, and dual-port FIFOs in a single device. The 200 MHz internal performance quoted in vendor data sheets refers to typical LE toggle rates, with system throughput bounded by I/O and interconnect delays at higher logic utilization. Typical applications include industrial glue logic, legacy peripheral bus bridges, telecommunications line-card control, military and avionics retrofits, and educational FPGA development platforms. The wide PQFP package also makes it convenient for prototype work using breakout adapters and through-hole solderless breadboards. When designing with this part, note that PQFP packages demand careful PCB layout for impedance control and thermal dissipation; the commercial-grade die does not target AEC-Q100 automotive qualification, and modern ACEX-1K designs should be migrated to Cyclone IV or MAX 10 families when long-term supply is required, since ACEX-1K is now classified as mature/last-time-buy at Intel FPGA. This page synthesizes distributor pricing, drop-in compatible alternatives sourced from the same ACEX-1K family, and practical design notes not found in the manufacturer datasheet.
EP1K10QC208-3 - 10K Gate ACEX-1K FPGA, 208-PQFP | Intel / Altera
The Intel / Altera EP1K10QC208-3 is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs) delivering 10,000 typical gates, 576 logic elements (LEs), and 12,288 RAM bits in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. The device operates from a 2.5 V core supply and is built on a 0.22 µm SRAM-based CMOS process, supporting in-system programmability via an industry-standard configuration interface. An FPGA (Field Programmable Gate Array) is a reconfigurable integrated circuit whose logic function is defined by a user-supplied configuration bitstream rather than by fixed factory mask wiring. FPGAs sit within the broader programmable logic hierarchy: PLD (Programmable Logic Device) -> CPLD (Complex PLD) -> FPGA. Compared with fixed-function ASICs, FPGAs trade raw performance-per-watt and unit cost for design flexibility, fast prototyping, and field-upgradability, making them the dominant platform for low-to-medium volume digital logic, glue logic, DSP pipelines, and I/O expansion. Key features of the EP1K10QC208-3 include 120 user I/O pins, 72 LABs (Logic Array Blocks) organized in a dual-port Embedded Array Block (EAB) fabric, an internal core clock network supporting up to 200 MHz operation, and 6 dedicated clock inputs. The -3 speed grade places this part in the faster tier of the ACEX-1K family, and the 'QC' package suffix identifies the 208-pin PQFP variant. The device supports hot-socketing and multi-voltage I/O standards including LVTTL, LVCMOS, PCI, and SSTL. The architecture is built around an Enhanced Embedded Array for implementing megafunctions such as efficient memory and specialized logic functions, with dual-port EABs that can be configured as RAM, ROM, or FIFO. Logic is implemented in a 4-input look-up table (LUT) per LE, with dedicated carry chains for arithmetic and a rich interconnect fabric (FastTrack) for predictable timing closure. Typical applications include glue logic in industrial controllers, I/O expansion for microcontrollers, low-cost DSP preprocessing, custom peripheral interfacing, and legacy system upgrades where the original ACEX-1K design cannot be re-engineered. The PQFP-208 package is well suited to through-hole prototype boards and older manufacturing lines that cannot accept fine-pitch BGA packages. When designing with this device, note that the ACEX-1K family is mature and has been classified NRND (Not Recommended for New Designs) by Intel/Altera; new designs should consider Cyclone or MAX II families. Configuration requires an external EPROM, EEPROM, or controller-based scheme and JTAG for in-system programming. This page synthesizes distributor pricing, ACEX-1K family datasheet excerpts, and drop-in ACEX-1K alternatives across the 208-PQFP footprint that are not collated in any single manufacturer document.
EP1K10QC208-3N - ACEX-1K FPGA, 10K Gates, 208-PQFP | Intel / Altera
The Intel (formerly Altera) EP1K10QC208-3N is an ACEX-1K series Field-Programmable Gate Array (FPGA) housed in a 208-pin Plastic Quad Flat Pack (PQFP/BQFP) package. It integrates 10,000 typical gates with 576 logic elements (LEs), 12,288 RAM bits, and 72 Logic Array Blocks (LABs), exposing 120 user I/O pins. Built on a 0.22 µm CMOS process at 2.5 V core, the -3 speed grade delivers up to 200 MHz internal operation, making it a benchmark mid-density legacy FPGA. An FPGA (Field-Programmable Gate Array) is a reprogrammable semiconductor whose logic fabric, consisting of configurable logic blocks (LBs/LABs) interconnected by a programmable routing matrix, lets designers implement arbitrary digital circuits. FPGAs sit between fixed-function Application-Specific Integrated Circuits (ASICs) and software-programmable microcontrollers in the design hierarchy: ASIC -> FPGA -> CPLD -> Microcontroller -> Microprocessor. The ACEX-1K family specifically pioneered embedded array blocks (EABs) that combine look-up-table logic with dedicated dual-port RAM, accelerating data-path and DSP designs for the early 2000s. Key features include embedded dual-port SRAM via EABs, multi-volt I/O supporting 2.5 V and 3.3 V interfaces, in-system programmability through the IEEE 1149.1 JTAG port, and on-chip phase-locked loops for clock management. The 208-BQFP variant is a metric quad flat pack with a generous perimeter-I/O arrangement, well suited for legacy industrial backplanes where through-hole or surface-mount gull-wing leads are preferred over fine-pitch BGAs. Typical applications span industrial control, telecommunications glue logic, glue/bridge functions in telecom line cards, prototyping for ASIC designs, and legacy military/aerospace retrofits. The 120 user I/Os and 12 Kbits of block RAM enable moderate-complexity state machines and small FIFO buffers. When designing with this device, remember that ACEX-1K predates modern configuration schemes - it requires an EPC configuration EPROM or microcontroller-driven passive serial configuration. Designers migrating to contemporary Cyclone or MAX families should evaluate Cyclone II/III/IV as functional successors, accepting full PCB redesign because no pin-compatible modern equivalent exists.
EP1K10TC100-1 - ACEX 1K FPGA, 10K Gates, 100-TQFP | Altera
The Altera (Intel) EP1K10TC100-1 is a member of the ACEX 1K family of Field Programmable Gate Arrays (FPGAs), delivering 10,000 typical gates and 576 logic elements in a 100-pin Thin Quad Flat Pack (TQFP) package. The device operates from a 2.5V core supply, is fabricated on a 0.22 µm CMOS process, and supports system clock frequencies up to 250 MHz. The "-1" speed grade denotes the commercial-temperature ACEX 1K performance tier. An FPGA is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that allow the hardware function to be defined after manufacture. ACEX 1K belongs to the low-cost, 2.5V SRAM-lookup-table (LUT) based FPGA family from Altera and is one generation below the APEX and Cyclone product lines. Within the broader programmable logic taxonomy, ACEX 1K sits between classic CPLDs (smaller, non-volatile, lower density) and modern high-density FPGAs such as Cyclone and Stratix. Key features of the EP1K10TC100-1 include 12,288 bits of embedded dual-port SRAM, 72 logic array blocks (LABs), 66 user I/Os, JTAG-compliant boundary-scan test support (IEEE Std 1149.1), and embedded array blocks (EABs) that can be configured as memory or specialized logic functions such as multipliers and DSP primitives. The TQFP-100 footprint is a JEDEC-standard surface-mount package suitable for conventional reflow assembly. Typical applications include glue logic replacement, custom interface bridging (UART, SPI, I²C, parallel bus), low-density DSP, industrial control, telecommunications line cards, prototyping of ASIC functions, and educational platforms. Because ACEX 1K devices are SRAM-based, they must be configured at every power-up from an external configuration memory (EPCS or compatible), which is a key system-level design consideration. When designing with this FPGA, ensure that a 2.5V regulator with adequate decoupling is placed close to the VCCINT pins, that JTAG chain integrity is verified, and that I/O bank voltage compatibility (VCCIO) is matched to the connected peripherals. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
EP1K10TC100-1N - ACEX-1K 10K Gates 250MHz FPGA | Intel
The Intel EP1K10TC100-1N is a member of the ACEX-1K family of Field-Programmable Gate Arrays (FPGAs), delivering 10,000 usable gates, 576 logic elements, and 12,288 bits of embedded RAM in a 100-pin TQFP surface-mount package. Built on a 0.22 µm CMOS SRAM process, the device operates from a 2.5 V core supply (range 2.375 V to 2.625 V) and is rated for commercial temperature operation from 0 °C to 70 °C with 66 user I/O pins available. According to the manufacturer datasheet, the -1N speed grade targets an internal frequency of approximately 180 MHz in the system. An FPGA (Field-Programmable Gate Array) is a class of programmable logic device (PLD) — within the broader taxonomy of integrated circuits, it sits below ASICs but above simple SPLDs/CPLDs in density. ACEX-1K devices integrate a sea of logic elements (LEs), embedded array blocks (EABs) that double as RAM/ROM, and a continuous routing network, allowing designers to implement arbitrary digital functions that are re-programmable in-system via SRAM configuration. ACEX-1K belongs to the Intel (formerly Altera) programmable logic family tree: PLD > CPLD/FPGA > SRAM-based FPGA > ACEX-1K. Key features include 72 Logic Array Blocks (LABs) arranged in a MegaLAB structure, 3 embedded array blocks of 4 Kbit each (12 Kbit total EAB) usable as 12,288 bits of RAM, JTAG (IEEE 1149.1) boundary-scan support, and multiVolt I/O compatible with 2.5 V/3.3 V/5 V mixed-voltage systems. The 100-pin TQFP package provides a low-profile 1 mm-height footprint with gull-wing leads, enabling placement on compact PCBs and standard surface-mount assembly lines. The -1N speed grade designates the slower commercial-tier silicon of the family, prioritizing cost over fMAX. Typical applications include glue-logic bridges in telecom line cards, industrial control and factory-automation backplanes, low-density data-path processing, custom interface conversion (e.g., UART/SPI/I2C bridging), and legacy peripheral replacement in systems that still specify ACEX-1K. Designers choose this part when an EEPROM- or flash-free volatile configuration stream is acceptable (an external configuration memory such as an EPC2 or EPCS is required at boot), and when pin count, I/O count, and logic density are matched. Designers should plan for an external configuration PROM (EPC2, EPCS1, or EPCS4 depending on bitstream size) because the ACEX-1K is SRAM-based and loses configuration at power-down. The 100-pin TQFP footprint provides convenient soldering and rework compared to BGA alternatives, but limits I/O expansion to 66 pins; designs exceeding that count require migration to the EP1K10QC208-3 or EP1K10FC256-3 package options in the same family. This page synthesizes distributor availability, drop-in alternatives from the same ACEX-1K family, and engineering design notes that complement the manufacturer's datasheet. Pricing reflects current distributor listings as of 2026-09-07.
EP1K10TC100-2 - 10K-Gate ACEX-1K FPGA, 576 LEs, TQFP-100 | Intel

It integrates 576 logic elements, 72 logic array blocks, 12,288 bits of embedded RAM, and 66 user I/O pins on a 2.5V CMOS fabric built on a 0.22 μm process node. An FPGA (Field Programmable Gate Array) is a semiconductor IC containing an array of configurable logic blocks (LBs), programmable interconnect, and I/O cells that can be re-wired by the user to implement arbitrary digital circuits. Within the wider taxonomy, FPGAs sit above CPLDs and below ASICs in terms of integration density, and they belong to the broader category of programmable logic devices (PLDs). ACEX-1K parts are positioned at the low-density, low-cost end of the FPGA spectrum, intended for glue logic, bus bridging, and small state-machine applications where an ASIC is uneconomical. Key features include a 0.5 ns pin-to-pin logic delay, dual-port embedded memory, dedicated carry chains for fast arithmetic, JTAG-compliant IEEE 1149.1 boundary-scan, in-system programmability via the serial configuration interface, and support for multiple I/O standards including LVTTL, LVCMOS, and PCI. The device is rated for commercial 0 °C to 70 °C ambient operation and runs from a 2.375 V to 2.625 V core supply. The EP1K10TC100-2 uses a SRAM-based look-up-table (LUT) architecture with continuous, row-and-column interconnect. Configuration data is loaded from an external serial PROM or via JTAG; the design is volatile and must be re-loaded on every power-up, which differentiates ACEX-1K from one-time-programmable (OTP) anti-fuse families. Typical applications include industrial control glue logic, communications protocol bridging, low-volume custom peripherals, and legacy retrofit boards where a discontinued discrete-logic design must be consolidated into a single programmable device. The wide 2.5 V tolerance band simplifies multi-voltage design. When designing with this part, note that the ACEX-1K family has been EOL'd by Altera/Intel; design engineers should verify long-term availability or migrate to a Cyclone equivalent for new designs. Always include a configuration PROM and follow the recommended decoupling scheme (0.1 μF + bulk) on every VCCINT and VCCIO pin pair. This page consolidates distributor pricing, same-brand drop-in alternatives from the ACEX-1K family, and practical design notes not present in the original datasheet PDF.

The Altera (now Intel) EP1K10TC100-2N is a member of the ACEX-1K family of Field-Programmable Gate Arrays (FPGAs) featuring 10,000 typical gates and 576 logic elements, packaged in a 100-pin Thin Quad Flat Pack (TQFP). Built on a 0.22 um CMOS process and powered from a 2.5 V core supply, the device delivers up to 200 MHz system performance and provides 66 user I/O pins for moderate-density glue-logic, control, and signal-processing designs. The "-2N" speed grade identifies a commercial-temperature part with the second-fastest bin in the family, while the "TC100" suffix denotes the TQFP-100 package and lead-free finish. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the volume production economics of a standard IC with the design flexibility of custom logic. ACEX-1K belongs to the embedded-array branch of the FPGA taxonomy (FPGA -> PLD -> programmable logic -> digital IC -> semiconductor), integrating a lookup-table-based logic fabric with embedded array blocks (EABs) that can be configured as RAM, ROM, or multiplier primitives. This makes the EP1K10 well-suited to system-on-a-programmable-chip (SOPC) integration where the designer needs both glue logic and small blocks of memory or DSP. Key features of the EP1K10TC100-2N include 576 logic cells distributed across 72 logic array blocks (LABs), 12,288 bits of embedded memory, in-system programmability via the IEEE 1149.1 (JTAG) interface, and four-phase on-chip PLL support for clock management. The device supports configuration through passive serial, active serial (EPC2/EPC16), or JTAG modes, and is supported by the Altera Quartus II and MAX+PLUS II development environments. The -2 speed grade provides approximately 0.7 ns gate-delay typical timing at 25 C ambient. Architecturally, ACEX-1K cells consist of a 4-input look-up table (LUT), a programmable register, and carry-chain logic that feeds the next cell, enabling efficient arithmetic and counter operations. The 100-pin TQFP footprint uses a thin (1.0 mm) body with gull-wing leads on a 0.5 mm pitch, making it hand-solderable and compatible with low-cost two-layer PCB assembly flows. Multi-voltage I/O banks allow 1.8 V, 2.5 V, 3.3 V, and 5 V interfacing without external level shifters. Typical applications include industrial control and glue logic, low-density communication bridges, PCI/ISA bus interfaces, custom register-decoder and state-machine designs, educational FPGA platforms, and legacy design maintenance where the original ACEX-1K footprint must be preserved. Designers porting older ACEX-1K designs can drop the EP1K10TC100-2N directly onto an existing PCB without layout changes. When designing with this part, observe the IOREF pin configuration for mixed-voltage operation, ensure the JTAG chain includes appropriate TCK pull-down and TDI/TMS pull-up resistors, and follow Altera's power-up sequencing recommendations for the 2.5 V VCCINT and 3.3 V VCCIO rails. Quartus II 13.0 or earlier is the last officially supported toolchain, which is an important consideration for new design starts. This page synthesizes distributor pricing, drop-in same-package alternatives within the ACEX-1K family, and practical design notes that go beyond what is printed in the original datasheet.

A Field-Programmable Gate Array (FPGA) is a reconfigurable integrated circuit that lets designers implement custom digital logic, state machines, datapaths, and interface bridges after PCB fabrication. FPGAs occupy the broad hierarchy of programmable logic devices (PLD) -> CPLD/FPGA -> programmable logic -> digital semiconductor. The ACEX-1K series, introduced by Altera (later acquired by Intel), targets cost-sensitive glue-logic, bus-bridging, and low-density state-machine applications where ASIC NRE is unjustified. Key features of the EP1K10TC100-2NGZ include 72 logic array blocks (LABs), 12,288 bits of embedded SRAM distributed across the fabric, support for Altera's Quartus II design suite, in-system programmability via JTAG, and a commercial 0 °C to 70 °C operating temperature range. The 100-TQFP footprint allows hand-solderable prototyping on standard 0.5 mm-pitch land patterns, eliminating the need for BGA reflow equipment in small-volume builds. Typical applications include industrial control interfaces, legacy parallel-bus bridges (PCI, ISA), telecommunications glue logic, instrumentation front-end controllers, and education platforms where TQFP packages simplify lab rework.

When designing with this device, verify that your Quartus II tool version still supports the ACEX-1K device family, and budget for legacy support contracts or migration to Cyclone-series devices for new designs. Always confirm the supply-voltage tolerance against the host 2.5 V rail, and respect the 66-user-I/O limit when assigning pin functions. This page synthesizes distributor stock data, drop-in pin-compatible ACEX-1K alternatives, and Quartus II design considerations not consolidated in a single manufacturer datasheet, giving procurement and FPGA engineers a one-stop reference for sourcing and replacing this legacy Intel/Altera part.
EP1K10TC100-3 - ACEX-1K 10K Gates FPGA 100-TQFP | Intel / Altera
The Intel (formerly Altera) EP1K10TC100-3 is a member of the ACEX-1K family of Field-Programmable Gate Arrays (FPGAs) housed in a 100-pin TQFP package. It integrates 10,000 typical gates, 576 logic elements (LEs), and 12,288 RAM bits, delivering up to 200 MHz system performance on a 0.22 µm CMOS process with a 2.5 V core supply. The ACEX-1K family is a low-cost System-on-a-Programmable-Chip (SOPC) platform featuring embedded array blocks (EABs) for memory and specialized logic functions, including true dual-port RAM capability in select configurations. What is an FPGA? A Field-Programmable Gate Array (FPGA) is a reconfigurable semiconductor device containing an array of programmable logic blocks, interconnect resources, and I/O cells that engineers can customize after manufacture to implement arbitrary digital logic. Within the broader programmable logic hierarchy, FPGAs sit between simple Complex Programmable Logic Devices (CPLDs) and high-end ASICs, offering higher logic density than CPLDs and faster time-to-market than ASICs. ACEX-1K belongs to the low-cost, low-power tier of legacy FPGAs optimized for glue logic, bus bridging, and moderate-complexity state-machine designs. Key features include 72 LABs (Logic Array Blocks) and 66 user I/O pins, with built-in PCI compliance support and JTAG-based IEEE 1149.1 boundary-scan test capability. The -3 speed grade is the fastest commercial speed grade offered for this device family, providing the highest Fmax among ACEX-1K variants. The device supports multiple I/O standards including LVTTL, LVCMOS, and PCI, allowing flexible interfacing with mixed-voltage systems without external level shifters. The EP1K10TC100-3 is built on a 0.22 µm four-layer metal CMOS process, with EABs providing 4 Kbit embedded memory blocks that can be configured as RAM, ROM, or FIFO. Architectural depth also includes dedicated carry chains for fast arithmetic, cascade chains for wide fan-in functions, and a structured ASIC-like interconnect that improves timing predictability versus earlier FPGAs. Typical applications include industrial control glue logic, low-density communication bridge devices, PCI bus interface controllers, and legacy embedded system upgrades. The 100-pin TQFP package supports conventional SMT assembly on 2-layer or 4-layer PCBs without requiring BGA-class PCB fabrication capabilities. Engineers commonly deploy this device in cost-sensitive designs where modern Cyclone or MAX II FPGAs exceed the BOM budget. Designers should leverage Altera Quartus II (legacy versions MAX+PLUS II or Quartus II 7.2 and earlier) for synthesis, place-and-route, and programming file generation. Note that ACEX-1K is no longer in active production - new designs should evaluate Cyclone II/III/IV as modern replacements when supply allows. This page synthesizes verified distributor stock, datasheet specifications, and ACEX-1K family drop-in alternatives not consolidated in any single manufacturer datasheet.
EP1K10TC100-3N - 10K-Gate ACEX-1K FPGA, 576 Cells, 66 I/O, 100-TQFP | Intel / Altera
The Intel / Altera EP1K10TC100-3N is a member of the ACEX-1K FPGA family, providing 10,000 typical gates, 576 logic elements (cells), and 12,288 bits of embedded SRAM in a 100-pin Thin Quad Flat Pack (TQFP) package. Built on a 0.22 µm CMOS process with a 2.5 V core supply, this device operates at a maximum internal clock frequency of 200 MHz and is offered in a -3 commercial speed grade. The device exposes 66 user I/O pins and integrates a PCI-compliant I/O structure, allowing direct interfacing with 5.0 V PCI bus signals at 33 MHz. An FPGA (Field Programmable Gate Array) is a programmable logic device that combines configurable logic blocks, programmable interconnect, and I/O cells on a single silicon die, enabling the implementation of arbitrary digital circuits without mask or tooling costs. Within the broader taxonomy of integrated circuits, FPGAs sit alongside CPLDs, microcontrollers, and ASICs as a flexible alternative to fixed-function logic. The ACEX-1K family specifically delivers low-cost system-on-a-programmable-chip (SOPC) integration, combining dedicated embedded array blocks (EABs) for memory and specialized logic functions with a general-purpose logic array. This hierarchy makes ACEX-1K parts an intermediate-density choice between small CPLDs and high-density Stratix-class FPGAs. Key features of the EP1K10TC100-3N include 72 Logic Array Blocks (LABs), built-in Joint Test Action Group (JTAG) boundary-scan test circuitry compliant with IEEE Std. 1149.1-1990, dual-port EAB memory for efficient FIFO and RAM implementation, and PCI Local Bus Specification Revision 2.2 compliance at 5.0 V operation. The device supports in-system programmability via configuration devices or the JTAG port, eliminating the need for external boot PROMs in many designs. The TQFP-100 footprint provides a 14 mm × 14 mm body suitable for cost-sensitive through-hole-style surface-mount assembly. From an architectural perspective, the EP1K10TC100-3N arranges its 576 logic elements into 72 LABs of 8 elements each, with each element containing a 4-input look-up table, a programmable register, and dedicated carry chain logic for arithmetic functions. The embedded array blocks (EABs) implement dual-port RAM, ROM, or specialized megafunctions, providing up to 12,288 bits of fast on-chip memory. The 0.22 µm CMOS process and 2.5 V core reduce dynamic power relative to older 5 V FPGAs while maintaining TTL-compatible I/O through PCI-compliant drivers. Typical applications include PCI bus interface glue logic, low-volume prototyping of digital signal processing pipelines, industrial control state machines, glue logic for embedded microprocessor systems, and legacy design maintenance. The 66 user I/Os and 12 Kb of embedded memory are well matched to glue-logic bridges, custom peripheral controllers, and small DSP front-ends. When designing with this part, engineers should note that the ACEX-1K family has been superseded by Cyclone-series FPGAs in modern designs. The Quartus design tool (versions up to 13.0) supports this device, but new development should consider Cyclone II/III for active lifecycle status and improved power efficiency.

EP1K10TC144-1 - ACEX-1K FPGA, 10K Gates, 144-LQFP | Intel / Altera
The Intel (formerly Altera) EP1K10TC144-1 is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs) featuring 10,000 typical gates, 576 logic elements (LEs), and 12,288 RAM bits, housed in a 144-pin LQFP (TQFP) package with 92 user I/Os. It is built on a 0.22 µm EEPROM process with a 2.5 V core supply, supporting commercial-grade operation. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, all of which can be customized after manufacturing. FPGAs sit at the top of the programmable logic hierarchy, above CPLDs and SPLDs, and are widely used for glue logic, signal processing, bus interfacing, and prototyping where ASIC NRE costs cannot be justified. The ACEX-1K family is an early-2000s SRAM/EEPROM-based architecture from Altera, designed for low-cost system-on-a-programmable-chip (SOPC) integration. Key features of the EP1K10TC144-1 include 72 logic array blocks (LABs), an embedded array block (EAB) for efficient memory and specialized logic functions such as multipliers and DSP primitives, dual-port RAM support, and 12,288 bits of embedded memory. The device supports JTAG-based in-system programmability (ISP) via the IEEE 1149.1 boundary-scan interface, simplifying field updates and manufacturing flows. The EP1K10TC144-1 uses a Look-Up Table (LUT)-based fine-grained architecture with 4-input LUTs feeding flip-flops in each LE. Each LAB contains 12 LEs with associated carry and cascade chains. The EAB blocks provide 2 Kbits of dual-port RAM each, configurable as RAM, ROM, or FIFO. This combination makes the device suitable for moderate-complexity glue logic, state-machine controllers, and small FIFO/buffer applications where non-recurring engineering (NRE) costs of an ASIC would be prohibitive. Typical applications include industrial control glue logic, telecommunications interface bridging, legacy peripheral controllers, and educational/prototyping boards. The 144-LQFP package offers ease-of-assembly for through-hole-friendly prototyping and rework, while the 92 available I/Os provide sufficient connectivity for parallel buses, sensor aggregation, and human-machine interface (HMI) tasks. When designing with this part, note that the ACEX-1K family is now considered legacy and is in obsolescence transition; design teams should confirm long-term supply availability with Intel PSG or authorized distributors before committing to new designs. Configuration data must be loaded from a serial or parallel PROM at every power-up because the SRAM-based configuration cells are volatile.
