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

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

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.

EP1K10QC208-3 - 10K Gate ACEX-1K FPGA, 208-PQFP | Intel / Altera
EP1K10QC208-3

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.

EP1K10QC208-3N

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

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.

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.

EP1K10TC100-2 - 10K-Gate ACEX-1K FPGA, 576 LEs, TQFP-100 | Intel

The Intel EP1K10TC100-2 is a member of the ACEX-1K programmable logic family that delivers up to 10,000 usable gates in a 100-pin TQFP surface-mount package. 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.

EP1K10TC100-2N

EP1K10TC100-2N - ACEX-1K FPGA, 10K Gates, 576 Cells | Altera

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.

EP1K10TC100-2NGZ

EP1K10TC100-2NGZ - 10K-gate ACEX-1K FPGA, 100-TQFP | Intel

The Intel EP1K10TC100-2NGZ is a member of the ACEX-1K programmable logic family, providing 10,000 typical gates and 576 logic elements in a 100-pin TQFP surface-mount package with 66 user I/O pins and 12,288 bits of embedded SRAM. Operating from a 2.375 V to 2.625 V core supply, the device is built on a 0.18 µm SRAM-based lookup-table architecture and is factory-marked Obsolete, with remaining inventory supplied through authorized distributors and the secondary market. 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. The EP1K10TC100-2NGZ is pin-compatible with other 100-TQFP ACEX-1K members, letting designers migrate between speed grades (-2 vs -3) and density options (10K vs 30K) without re-spinning the PCB. 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.

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.

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

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.

EP1K10TC144-1N - 10K-Gate ACEX-1K FPGA, 92 I/O, TQFP-144 | Intel

The Intel (formerly Altera) EP1K10TC144-1N 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 144-pin TQFP (Thin Quad Flat Pack) package. The device integrates 92 user I/O pins with 5V tolerant I/O capability and is fabricated on a 0.18 µm CMOS process operating from a 2.5 V core supply. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the high density of gate arrays with the design flexibility of programmable logic. FPGAs sit in the hierarchy: FPGA -> programmable logic -> ASIC alternative -> digital integrated circuit. ACEX-1K devices are low-cost, SRAM-based FPGAs targeting high-volume glue-logic, bus-interface, and DSP co-processing applications where mid-range logic density is required without the cost of higher-end FPGA families. Key features of the EP1K10TC144-1N include a maximum internal operating frequency of 250 MHz, embedded array blocks (EABs) implementing dual-port RAM, ROM, or FIFO functions, and a MultiVolt I/O interface supporting 2.5 V and 3.3 V signalling. The device supports in-system programmability via configuration schemes including passive serial, passive parallel synchronous, and JTAG. Per-device power consumption is typically 0.5 mA quiescent current plus dynamic current dependent on toggle rate and logic utilization. Architecturally the EP1K10TC144-1N combines Logic Array Blocks (LABs) and Embedded Array Blocks (EABs). LABs implement general-purpose combinational and sequential logic while each EAB provides 4 Kbits of RAM that can be configured for synchronous single-port or dual-port memory. Fine-grained look-up tables (LUTs) drive efficient state-machine and arithmetic implementations, and dedicated carry chains support high-speed adders. Typical applications include industrial control interfaces, legacy bus-bridging glue logic, communication backplane controllers, low-cost DSP pre-processing, and educational/development platforms. The 144-pin TQFP footprint is well suited to through-hole-friendly prototyping PCBs while still allowing surface-mount assembly. When designing with the EP1K10TC144-1N, verify the configuration mode (typically passive serial for ACEX-1K) and EPC configuration memory compatibility. Use the Quartus II design software (legacy) or Max+Plus II to capture schematics and verify timing closure at 250 MHz worst-case.

EP1K10TC144-2 - ACEX-1K FPGA, 10K Gates, 144-LQFP | Altera

The Altera (now Intel) EP1K10TC144-2 is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGA) delivering 10,000 typical gates, 576 logic elements (LEs) and 12,288 RAM bits in a 144-pin LQFP (TQFP) package. The device integrates an enhanced embedded array for implementing megafunctions such as efficient memory and specialized logic functions, with dual-port RAM capability. It is fabricated on a 2.5 V core process and is offered in a commercial temperature grade. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be re-programmed after manufacture to implement arbitrary digital logic. FPGAs sit at the top of the programmable logic hierarchy between CPLDs (less complex, non-volatile, lower density) and ASICs (highest density, fixed function). The ACEX-1K family was Altera's first SRAM-based, look-up-table (LUT) FPGA family, designed as a low-cost System-On-a-Programmable-Chip (SOPC) integration platform bridging CPLD simplicity with FPGA density. Key features include 92 user I/O pins, dual-port embedded array blocks (EABs), in-system programmability via JTAG, and support for multiple I/O standards including LVTTL, LVCMOS and PCI. The device operates from a 2.5 V core supply with 3.3 V tolerant I/O options, and the 144-LQFP (also written TQFP-144) footprint is a JEDEC-standard surface-mount package with 1.0 mm pitch. The ACEX-1K architecture uses a fine-grained LUT-based logic element feeding into a hierarchical routing fabric with embedded array blocks (EABs) providing dual-port RAM and ROM. Per the Altera ACEX 1K Device Family datasheet (2.5V), each EAB can be configured from 256x8 to 4096x1 of true dual-port memory, enabling wide datapath and FIFO implementations without external memory. Configuration is volatile SRAM-based, so an external configuration memory (typically EPC2 or EPCQ) is required at power-up. Typical applications include glue logic replacement, bridge and protocol conversion (e.g., PCI to local bus), low-volume ASIC prototyping, industrial control and instrumentation front-ends, and embedded control DSP co-processing. The 144-LQFP package is hand-solderable and well suited to prototype runs and low-to-mid volume production. When designing with this part, note that the configuration memory (EPC2/EPCQ) must be specified separately and the JTAG chain length must be observed; because ACEX-1K is an older family, new designs should evaluate Cyclone IV/V or MAX 10 instead.

The Intel / Altera (formerly Altera Corporation) EP1K10TC144-2N is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs), delivering 10,000 typical gates, 576 logic elements, and 12,288 RAM bits in a 144-pin TQFP (TC) package. Housed in a thin plastic quad flat pack measuring 22 mm × 22 mm × 1.4 mm with a 0.5 mm lead pitch, the device offers 92 user I/O pins and operates across a commercial 0 °C to +70 °C ambient range, with the speed grade -2 providing balanced performance and power for general-purpose logic integration. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be re-programmed by the designer after manufacture. FPGAs sit at the top of the programmable logic hierarchy alongside CPLDs, occupying the intersection of ASIC-like density and software-driven design flexibility, and are widely used for glue logic, protocol bridging, and parallel DSP pipelines in industrial, communications, and test equipment. Key features include an embedded array block (EAB) architecture with 12 embedded array blocks implementing dual-port RAM, ROM, or multiplier functions; 72 logic array blocks (LABs) arranged across the die; built-in JTAG boundary-scan test circuitry compliant with IEEE 1149.1; and support for multiple I/O standards including LVTTL, LVCMOS, PCI, and SSTL through dedicated I/O banks. Configuration is handled by a serial PROM, controller, or JTAG port, and the device operates from a single 2.5 V core supply with separate VCCIO rails for the I/O banks. Typical applications include glue logic replacement on legacy PC/104 and VME boards, custom state-machine controllers in industrial automation equipment, low-density DSP pre/post-processing pipelines, and peripheral bridging (UART, I²C, SPI) in networking line cards. The 92 available I/O pins comfortably drive 8-bit or 16-bit parallel buses plus control signals, while the 12 Kbit embedded RAM supports small FIFO and lookup-table implementations without external memory. Designers should pay particular attention to I/O bank voltage constraints: the EP1K10TC144-2N supports 2.5 V and 3.3 V on the same die, but mixing 5 V inputs requires external resistor dividers since the device has no 5 V-tolerant I/O. Quartus II design software (version 13.0 or earlier is the last release supporting ACEX-1K) is required for synthesis, place-and-route, and bitstream generation.

Built on a 2.5V, 0.22 µm CMOS SRAM-lookup-table (LUT) process, the device integrates an embedded array of dual-port RAM blocks with a logic array to deliver megafunction-level integration for low-cost system-on-a-programmable-chip (SOPC) designs. The "-3" speed grade targets commercial timing closure at up to 200 MHz internal operation. A Field-Programmable Gate Array (FPGA) is a reconfigurable digital IC whose logic function is defined by user-supplied configuration bitstreams stored in on-chip SRAM. The ACEX-1K family belongs to the broader taxonomy of programmable logic devices (PLD), which spans simple PLDs, complex PLDs (CPLD), and FPGAs. Within Intel's / Altera's portfolio, the ACEX-1K sits between the older FLEX family and the Cyclone series, sharing the LUT-based fabric of modern FPGAs while keeping a low unit cost that made it popular in glue-logic, bus-interface, and low-volume telecom designs of the early 2000s. Key architectural features include four embedded array blocks (EABs) implementing dual-port RAM up to 4 Kbits each, dedicated carry chains for fast arithmetic, and JTAG-based in-system programmability through the IEEE 1149.1 boundary-scan interface. The LUT-based logic elements offer fast combinatorial paths, and the device is supported by the Quartus II design suite (legacy) for synthesis, place-and-route, and timing analysis. Note that ACEX-1K devices are no longer recommended for new designs. Typical applications include communications interface bridging, peripheral expansion in embedded motherboards, glue logic between microprocessors and memory buses, low-volume industrial control, and legacy design maintenance. The 92 available I/Os and 12 Kbits of block RAM make it well suited to bus-protocol conversion and small FIFO buffering tasks. When designing with this part, ensure the 2.5V VCCINT and 3.3V-tolerant VCCIO rails are decoupled per the Altera ACEX-1K handbook, and that configuration is supplied through a stable EPC or microcontroller loader because the SRAM fabric loses configuration on power-down.

It is built on a 0.22 um CMOS process with a 2.5 V core supply and supports -1 speed-grade PCI compliance at 5.0 V I/O. The device is offered in the -3N speed grade, indicating enhanced timing performance versus the -1 and -2 grades within the same family. An FPGA (Field Programmable Gate Array) is a programmable logic device that allows designers to implement arbitrary digital logic functions through a sea of configurable logic blocks (LBs), embedded memory blocks, and programmable interconnect. The ACEX-1K family sits in the hierarchy as an SRAM-based, look-up-table (LUT) FPGA below the more complex APEX and later Cyclone families. FPGAs of this class are widely used in glue logic, bus interfacing, and low-to-medium density state-machine implementations where mask-programmed gate arrays would otherwise be uneconomical. Key features of the EP1K10TC144-3N include 92 user I/O pins (out of 144 package pins), built-in dual-port RAM capability, and integrated Joint Test Action Group (JTAG) boundary-scan test circuitry compliant with IEEE Std. 1149.1-1990. The -3N speed grade corresponds to faster internal timing than the -1N and -2N grades of the same die, making it suitable for throughput-sensitive control logic. The embedded array block (EAB) architecture supports megafunctions such as efficient memory, multipliers, and specialized peripheral logic. Typical applications include PCI bus interface bridging, telecommunications line-card glue logic, industrial control state machines, and legacy replacement for discrete TTL/CMOS logic. The 144-LQFP package allows hand-repairable assembly and standard surface-mount manufacturing flows. The 'N' suffix typically indicates an industrial temperature grade or lead-free / Pb-free assembly, which engineers should confirm against the manufacturer datasheet for the exact revision. When designing with the EP1K10TC144-3N, ensure the Quartus II or MAX+PLUS II toolchain is configured for the ACEX-1K family and that the I/O voltage bank assignments match the system logic.

EP1K10TC144-3N - ACEX 1K FPGA, 10K Gates, 144-TQFP | Altera

The Altera EP1K10TC144-3N is a member of the ACEX 1K programmable logic device family built on a 2.5 V CMOS process with 10,000 typical gates (equivalent to 56,000 logic gates in normalized metrics), delivering an 80 MHz system performance and packaged in a 144-pin TQFP (TQ144). The part features 576 logic elements distributed across 72 logic array blocks (LABs), 12,288 bits of embedded array block (EAB) RAM organized as dual-port memory, and 92 user I/Os that meet PCI Local Bus Specification Revision 2.2 for 5.0 V operation. A Field Programmable Gate Array (FPGA) is a programmable logic device that lets engineers implement arbitrary digital logic by configuring an array of configurable logic blocks (CLBs), embedded memory blocks, and routing resources via SRAM-based configuration cells. FPGAs sit at the top of the programmable logic hierarchy: PLD -> CPLD -> FPGA -> SoC FPGA. The ACEX 1K family occupies the cost-optimized SOPC (system-on-a-programmable-chip) tier of legacy Altera FPGAs, providing dual-port RAM, megafunction support via the embedded array, and JTAG IEEE Std. 1149.1 boundary-scan test (BST). Key differentiating features include a dedicated EAB architecture for efficient memory and specialized logic functions, dual-port RAM for FIFO/buffer designs, built-in JTAG boundary-scan (IEEE 1149.1) that consumes no additional device logic, and -3 speed grade timing with 80 MHz performance. The TQFP-144 thermal envelope (plastic quad flatpack with exposed lead-frame pads) supports fanless industrial designs at moderate toggle rates, and the 2.5 V core with PCI-compliant I/Os simplifies 3.3 V/5 V mixed-rail board designs. The ACEX 1K architecture couples four-input look-up tables (LUTs) per logic element with a programmable flipflop, dedicated carry and cascade chains for fast arithmetic, and a local interconnect within each LAB that lets eight LEs implement medium-sized blocks such as 8-bit counters or address decoders without consuming global routing. Configuration is SRAM-based and reloadable, allowing in-system updates. Typical applications span glue logic, bus bridges, custom peripheral controllers, and low-cost glue ASIC replacement in industrial control, telecom line cards, test and measurement front-ends, and PCI peripherals. Designers favor this family when 10K-gate density, embedded dual-port RAM, and 5V-tolerant I/Os matter more than absolute state-of-the-art logic capacity. Design consideration: the 2.5 V core requires careful power sequencing versus 3.3 V I/O rails, and the SRAM configuration memory means an external configuration PROM (EPCS or compatible) is mandatory for volatile-free boot. The -3 speed grade is the fastest commercially available bin for this die.

The Intel / Altera EP1K10TI100-2 is a member of the ACEX-1K family of FPGAs (Field Programmable Gate Arrays), built on a 0.22 µm CMOS SRAM process and offering 10,000 typical gates, 576 logic elements, and 12,288 RAM bits in a 100-pin TQFP package with 66 user I/Os. The "I" suffix designates the industrial temperature grade (-40 °C to +85 °C) and the "-2" speed grade corresponds to a faster performance bin, supporting internal toggle frequencies up to 200 MHz. An FPGA (Field Programmable Gate Array) is a programmable logic device containing an array of configurable logic blocks (CLBs), embedded memory, and programmable interconnect that the designer can configure after manufacturing to implement any digital logic function. FPGAs sit hierarchically between fixed-function ASICs (Application Specific Integrated Circuits) and CPLDs (Complex Programmable Logic Devices), offering higher logic density and richer I/O features than CPLDs but lower performance-per-watt and higher unit cost than volume-production ASICs. The ACEX-1K family was Altera's first FPGA family to embed dedicated dual-port RAM (EAB) blocks alongside the logic fabric. Key features of the EP1K10TI100-2 include 72 LABs (Logic Array Blocks) each containing 8 logic elements, 3 embedded array blocks (EABs) providing 12,288 total RAM bits, four low-skew global clock networks, multi-voltage I/O support (2.5 V core with 3.3 V / 5 V tolerant I/O on selected banks), and in-system programmability via the IEEE 1149.1 JTAG interface or the Altera EPC serial configuration device. The device architecture combines an SRAM-based look-up table (LUT) logic fabric with fast carry chains for arithmetic, distributed inter-LAB routing, and dedicated phase-locked loops on higher-density ACEX-1K members (the EP1K10 is the smallest member and does not include PLLs). It targets glue-logic, bus-bridging, and state-machine consolidation designs where the 10K-gate capacity is sufficient. Typical applications include industrial control interfaces, communications glue logic, legacy 8051/microcontroller bus expansion, I/O buffering and level translation, custom state machines, and low-volume prototyping where the design may later migrate to a structured ASIC. When designing with this part, note that the 100-pin TQFP limits I/O count to 66 and the absence of on-chip PLLs constrains clock management; designers needing more I/O or clock synthesis should migrate to the EP1K30 / EP1K100 in TQFP-144 or larger packages. Power estimation requires Altera's PowerPlay tool because static and dynamic power depend heavily on utilization and toggle rate.

EP1K10TI100-2N

EP1K10TI100-2N - ACEX-1K 10K Gates FPGA 100-TQFP | Intel / Altera

The Intel (formerly Altera) EP1K10TI100-2N is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs) built on a 0.22 micrometer CMOS process with 2.5V core voltage, offering 10,000 typical gates, 576 logic elements (LEs) arranged in 72 Logic Array Blocks (LABs), and 12,288 bits of embedded SRAM in a 100-pin TQFP package. An FPGA (Field Programmable Gate Array) is a programmable logic device containing an array of configurable logic blocks (CLBs/LABs), programmable interconnects, and I/O cells. FPGAs belong to the broader category of programmable logic devices (PLDs), sitting above simple PLDs and CPLDs in complexity, and are widely used as application-specific integrated circuit (ASIC) prototypes and low-volume custom digital logic. The ACEX-1K family from Altera/Intel targets low-cost system-on-a-programmable-chip (SOPC) integration, embedding dual-port RAM and megafunction support such as efficient memory and specialized logic functions, while implementing designs at speeds up to 200 MHz. Key features include 66 user I/O pins, industrial temperature grading (-40C to +85C), a 100-pin Plastic Thin Quad Flat Pack (TQFP, also referenced as LFQFP) gull-wing surface-mount package, and the -2N speed grade indicating an internal performance bin. The -2 speed grade offers a balance between timing closure and cost; the N suffix indicates lead-free / Pb-free assembly. Designers can implement megafunctions including dual-port RAM, FIFO buffers, DSP blocks, and standard interfaces, all backed by Altera's Quartus II design suite. Technically, the EP1K10TI100-2N uses a continuous, segmented routing architecture with every LAB containing 8 LEs, each LE carrying a 4-input LUT, programmable register, carry chain, and cascade chain. The embedded array blocks (EABs) provide true dual-port RAM up to 4 Kbits each, configurable to various widths. The device operates from a 2.5V core with multi-voltage I/O support through banked VCCIO rails, typically 3.3V or 2.5V. Typical applications include glue logic in industrial control, communications protocol bridges, low-volume ASIC replacement, factory automation controllers, wireless baseband glue, and medical instrumentation. Designers migrating to newer Cyclone or MAX families should note that ACEX-1K is now legacy; the recommended modern replacement is the Cyclone IV family in compatible footprints. When designing with this device, ensure your Quartus II version supports ACEX-1K (legacy device support) and budget for I/O bank voltage compatibility if mixing 3.3V and 2.5V peripherals. The 100-TQFP package simplifies PCB layout with all-pin-perimeter access, but pay close attention to trace length matching for clock-distribution paths. This page synthesizes distributor pricing, drop-in alternatives from the same ACEX-1K family, and practical design considerations not always found in the original Altera datasheet - helping engineers make informed lifecycle decisions when sourcing a 25-year-old FPGA family.

EP1K10TI144-2 - ACEX 1K FPGA, 10K Gates, 144-TQFP | Intel / Altera
EP1K10TI144-2

EP1K10TI144-2 - ACEX 1K FPGA, 10K Gates, 144-TQFP | Intel / Altera

The Intel (formerly Altera) EP1K10TI144-2 is a CMOS Field Programmable Gate Array from the ACEX 1K device family, delivering 10,000 equivalent gates with 576 logic elements in a 144-pin TQFP (LFQFP) package. Per the verified distributor data, this part is fabricated on a 0.22 µm process, operates from a 2.5 V core supply, and supports up to 92 user I/O pins with a maximum clock frequency of 200 MHz (the same source quotes a lower 37.5 MHz figure on a separate listing, indicating datasheet variation; the 200 MHz figure is used as the headline). The "I" in the suffix denotes the Industrial temperature grade (-40 °C to +85 °C), and the "-2" speed grade positions this device in Altera's mid-range performance tier for the ACEX 1K family. An FPGA (Field Programmable Gate Array) is a programmable logic device that lets designers implement arbitrary digital logic through a configurable array of logic elements, embedded memory blocks, and routing interconnects. FPGAs sit in the broader category of programmable logic devices (PLDs), above simple CPLDs and below structured ASICs in terms of integration density. The ACEX 1K family targets low-cost, high-volume applications by combining look-up-table based logic with embedded array blocks (EABs) that double as dual-port RAM or ROM, enabling single-chip system-on-a-programmable-chip (SOPC) integration. Key features include 10K equivalent gates, 576 logic cells, 12 Kbits of embedded memory via embedded array blocks, in-system programmability through the IEEE 1149.1 JTAG interface, and a 2.5 V core with multi-voltage I/O support. The TQFP-144 package offers a 0.5 mm terminal pitch on a 22 mm × 22 mm body, suitable for socketed or hand-solderable designs in volume production. MultiVolt I/O supports interfacing with 3.3 V, 2.5 V, and 1.8 V peripherals without external level translation. The EP1K10TI144-2 is built on a SRAM-based configuration cell architecture, requiring a configuration device such as the Altera EPC2 or EPC8 for stand-alone operation. The embedded array blocks (EABs) support dual-port RAM, ROM, FIFO, and multiplier functions, making the device suitable for DSP pipelines and small state machines. Configuration is loaded serially or via JTAG, and the device supports multi-device configuration chains for larger systems. Typical applications include DSL modem glue logic, low-cost Ethernet switches, industrial control interfaces, glue logic for embedded processors, and small-volume prototyping where mask-programmed ASICs are uneconomical. Per the datasheet summary, the 2.5 V core enables low-power operation while the SameFrame pin-out across the ACEX 1K family supports migration to larger EP1K30 or EP1K50 devices on compatible footprints where available. When designing with the EP1K10TI144-2, plan the configuration memory interface early: the SRAM-based cells require a non-volatile configuration device on every board. Plan I/O bank voltage rails carefully, since each bank supports a single VCCIO level. Verify JTAG chain order before board bring-up to avoid configuration contention with other devices on the scan chain. This page consolidates distributor availability, drop-in same-package alternatives, and practical design notes beyond what the manufacturer datasheet provides in isolation.

The Altera (now Intel) EP1K30F256-3 is a member of the ACEX 1K family of Field Programmable Gate Arrays (FPGAs), delivering approximately 30,000 equivalent gates and 1,728 logic elements (LEs) organized into 216 Configurable Logic Blocks (CLBs), housed in a 256-ball FineLine Ball Grid Array (FBGA-256) package with the -3 speed grade designation. It provides 24576 RAM bits of embedded memory and supports a maximum clock frequency of 909 MHz, offering 171 user I/O pins for high-density logic integration in cost-sensitive applications. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that allows engineers to implement custom digital circuits through SRAM-based configuration cells, sitting at the top of the programmable logic hierarchy: PLD -> CPLD -> FPGA. ACEX 1K belongs to the older, mature Altera FPGA family based on a 0.18 µm CMOS SRAM process with on-chip Look-Up Table (LUT) architecture, providing true ASIC-like integration with field-reprogrammability. The -3 speed grade places it in the medium-performance tier of the family. Key features include 24576 bits of embedded SRAM organized as EAB (Embedded Array Blocks), in-system programmability via the IEEE 1532 / IEEE 1149.1 (JTAG) interface, MultiVolt I/O supporting 2.5V and 3.3V interfaces, and a built-in PLL for clock management. The device operates from a 1.8V core supply and supports multiple I/O standards including LVTTL, LVCMOS, PCI, and SSTL. The FBGA-256 package enables compact PCB designs with high I/O density. The EP1K30F256-3 utilizes an SRAM-based LUT architecture with embedded array blocks (EABs) for distributed memory, a configuration scheme that requires an external configuration device (such as EPC2 or EPC8) or microcontroller to load bitstream at power-up. The -3 speed grade delivers balance between cost and timing margin for industrial designs not requiring maximum Fmax. Typical applications include industrial control systems, telecommunications glue logic, ASIC prototyping, low-volume production replacements, and embedded control interfaces where FPGA flexibility is preferred over fixed-function ASICs. The ACEX 1K family remains in active service in legacy designs requiring long-term component availability. When designing with this device, plan for an external configuration PROM and a robust JTAG chain for in-system updates. Verify that the Quartus II design software version is set to support the ACEX 1K device family, and ensure PCB thermal design accounts for the FBGA-256 package's thermal resistance under maximum I/O toggle loading.
