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.

EP1K10TC144-2N - 10K Gate ACEX-1K FPGA, 92 I/O, TQFP-144 | Intel / Altera
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.
EP1K10TC144-3 - 10K Gate ACEX-1K FPGA 144-LQFP | Intel / Altera
The Intel / Altera EP1K10TC144-3 is a member of the ACEX-1K family of FPGAs featuring 10,000 typical gates, 576 logic elements (LEs), and 12,288 RAM bits in a 144-pin LQFP package with 92 user I/O pins. 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. Programming files are generated with Quartus II software. This page synthesizes distributor pricing, drop-in same-package alternatives, and design notes not found in the manufacturer datasheet.
EP1K10TC144-3N - 10K Gate ACEX-1K FPGA, 144-LQFP | Altera / Intel
The Intel (formerly Altera) EP1K10TC144-3N 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 LQFP (TQFP) package. 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. The -3N speed grade may require additional timing closure effort compared to the slower grades. This page synthesizes distributor availability, same-family drop-in alternatives (such as the -1N and -2N speed grades), and design considerations not consolidated in any single manufacturer document.
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.

EP1K10TI100-2 - 10K Gates ACEX-1K FPGA 66 I/O TQFP-100 | Intel / Altera
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. This page synthesizes distributor pricing, drop-in same-package alternatives within the ACEX-1K family, and design notes that complement the manufacturer datasheet.
EP1K10TI100-2N - ACEX-1K 10K Gates FPGA 100-TQFP | Intel / Altera

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
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. This page synthesizes distributor pricing, drop-in alternative ACEX 1K family members, and practical design notes not found in the standalone manufacturer datasheet, helping sourcing engineers quickly identify pin-compatible variants within the Altera ACEX 1K line.
EP1K30FC256-1 - 30K Gate ACEX-1K FPGA 256-BGA | Intel
The Intel (formerly Altera) EP1K30FC256-1 is a member of the ACEX-1K FPGA family, delivering 30,000 typical gates (17,280 logic elements / 1,728 logic cells) with 24,576 RAM bits in a 256-ball FineLine BGA package. It provides 171 user I/O pins and operates from a 2.5V core supply, with a -1 speed grade optimized for cost-sensitive commercial designs. What is an FPGA? A Field-Programmable Gate Array (FPGA) is a reconfigurable integrated circuit containing an array of programmable logic blocks, configurable interconnect, and embedded memory blocks that the designer programs after manufacture. The ACEX-1K family sits in the low-density, low-cost tier of the broader programmable logic hierarchy: CPLD (smaller, non-volatile) -> ACEX-1K / Cyclone (low-density SRAM FPGA) -> Cyclone II/III/IV/V (mid-density) -> Stratix (high-density) -> FPGA & CPLD category. SRAM-based FPGAs require a configuration flash at every power-up but deliver far higher logic capacity per dollar than CPLDs of the same era. Key features include embedded array blocks (EABs) for efficient memory and specialized logic function implementation, dual-port RAM support, 250 MHz internal performance, JTAG-based boundary-scan testing, and SameFrame pin-out compatibility that allows migration between density points and speed grades within the same 256-BGA footprint. The device is fabricated on a 2.5V CMOS process and supports in-system programmability via the Altera ByteBlaster or parallel configuration interfaces. The EP1K30FC256-1 architecture combines a fine-grained logic element array with coarse-grained embedded array blocks (EABs), enabling efficient implementation of both random logic and wide memory functions such as FIFOs, ROMs, and DSP-style multiplier-accumulator blocks. The 24,576 bits of distributed RAM and the 250 MHz system clock make the device suitable for glue-logic replacement, bus-interface bridging, and small-scale state-machine control in industrial and telecommunications equipment. Typical applications include glue logic replacement, bus-interface bridges (e.g., PCI to local bus), telecom line-card glue logic, industrial control and instrumentation front-ends, low-density DSP co-processing, and legacy system refresh designs that benefit from SameFrame footprint migration across the ACEX-1K family. The 171 user I/Os also make it suitable for display driving and parallel data acquisition front-ends. When designing with the EP1K30FC256-1, ensure the configuration device is selected to match the chosen configuration scheme (passive serial, passive parallel, or JTAG). Decoupling capacitors should be placed as close as possible to every VCCINT and VCCIO pin per Altera application note guidelines, and unused I/Os should be left floating or driven to a defined logic level.

The Intel (formerly Altera) EP1K30FC256-1N is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs) housed in a 256-ball FineLine BGA (FBGA) package. It integrates 30,000 typical gates, 1,728 logic elements (LEs), and 24,576 RAM bits into a single 2.5V device fabricated on a 0.22 µm SRAM process. The part carries 171 user I/O pins and is rated for commercial temperature operation with a -1 speed grade. An FPGA (Field Programmable Gate Array) is a reconfigurable digital integrated circuit that lets designers implement arbitrary logic functions through a programmable array of logic elements, embedded memory blocks, and routing interconnect. ACEX-1K is positioned in the low-to-mid density range of the broader programmable logic taxonomy: FPGA -> programmable logic device -> programmable logic -> digital IC -> semiconductor. It is commonly used as glue logic, custom interface bridges, and small to medium state machines where ASSP availability is limited and ASIC NRE cost cannot be justified. Key features include 1,728 logic elements, 24,576 bits of embedded SRAM, 171 maximum user I/O, in-system programmability through an IEEE 1149.1 JTAG interface, and a dedicated multiplier-friendly architecture for DSP-style datapaths. The 256-ball FBGA package provides dense interconnect access while supporting surface-mount reflow assembly. Core logic operates from a 2.5 V supply with separate VCCIO banks for I/O flexibility (2.5 V/3.3 V LVCMOS/LVTTL support is typical for the family). Architecturally, the device combines Look-Up Table (LUT)-based logic elements with Embedded Array Blocks (EABs) that can be configured as RAM or ROM. The ACEX-1K family is fabricated on a 0.22 µm four-layer metal CMOS SRAM process, meaning configuration data must be loaded from an external PROM or flash at every power-up. Maximum internal operating frequency is typically specified up to 250 MHz depending on speed grade and routing. Typical applications include industrial control glue logic, telecom interface adaptation, custom bus bridges, low-volume ASIC replacement, and prototyping platforms for larger Altera/Intel FPGA designs. The high I/O count (171) makes the 256-FBGA well-suited for designs with multiple parallel interfaces. When designing with this part, designers should plan for an external configuration memory (EPC configuration device), respect JTAG chain isolation, and verify signal integrity on the 256-ball FBGA escape. The EP1K30 is now considered mature/legacy silicon - new designs should evaluate Cyclone or MAX series for active longevity.

The Intel (formerly Altera) EP1K30FC256-2 is a 30,000-gate member of the ACEX-1K programmable logic family, integrating 1,728 logic elements across 216 configurable logic blocks (CLBs) in a 256-ball FineLine BGA package. The -2 speed grade targets a worst-case register-to-register delay of around 5 ns, placing the device in the mainstream 0.22 µm CMOS ACEX-1K performance tier with up to 200 MHz internal operation. On-chip memory totals 24,576 RAM bits distributed as dual-port EAB blocks, with 171 user I/O pins available for external interfacing. An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) within the broader integrated-circuit hierarchy (PLD -> programmable logic -> semiconductor). FPGAs provide hardware-reconfigurable digital logic, sitting between CPLDs and high-density ASICs in the design flexibility vs. cost spectrum, and ACEX-1K specifically targets cost-sensitive system-on-a-programmable-chip (SOPC) integration. Key features include built-in dual-port memory blocks (EABs) for efficient FIFO and buffer implementation, JTAG-based IEEE 1149.1 boundary-scan testing, MultiVolt I/O supporting 2.5 V core with mixed-voltage I/O banks, and SRAM-based configuration loaded from a serial PROM or via JTAG. The device operates from a 2.5 V core supply and supports commercial temperature grading. The ACEX-1K architecture combines a continuous embedded array for memory and specialized logic functions with a logic array for general-purpose registers and routing. This hybrid embedded/logic approach makes ACEX-1K efficient for designs requiring megafunctions such as multipliers, FIFOs, and DSP primitives, without paying the cost of a high-density APEX or Stratix-class device. Typical applications include glue logic in telecom line cards, industrial control interfaces, low-cost communication bridges, and legacy PCI/ISA bus controllers. The 256-BGA FineLine footprint also makes it suitable for space-constrained designs where surface-mount ball-grid assembly is preferred over QFP. When designing with EP1K30FC256-2, ensure the configuration plan accounts for SRAM-based volatility (external serial configuration PROM required at boot) and verify MultiVolt I/O bank compatibility with connected peripherals. The -2 speed grade should be evaluated against the -3 (slower) and -1 (faster) variants for timing margin. This page synthesizes distributor pricing, drop-in alternative part numbers, and practical design guidance not found in the manufacturer datasheet alone.

It is a low-cost programmable logic device built for system-on-a-programmable-chip (SOPC) integration, and this specific variant carries the -2 speed grade and the lead-free -N finish. A field-programmable gate array (FPGA) is an integrated circuit whose digital logic can be configured after manufacturing rather than being fixed at the factory. The FPGA sits inside the programmable logic device family, above it are programmable logic devices (PLDs), then integrated circuits, then semiconductors. In a typical system, an FPGA provides flexible glue logic, custom state machines, protocol bridging, and parallel compute structures that standard microcontrollers cannot easily implement, while retaining the ability to be reprogrammed during prototyping or production. Key features of the EP1K30FC256-2N include 216 logic array blocks, 24,576 RAM bits for on-chip FIFOs and buffers, and 171 user I/O pins. According to distributor and family datasheet summaries, the device can operate at internal clock frequencies up to 200 MHz and uses a 0.22 um process. The 2.5 V core supply permits low-power operation compared with earlier 5 V PLDs, while the 256-ball FBGA package provides a compact footprint for densely populated boards. From a technical standpoint, the ACEX 1K architecture combines logic elements with embedded array blocks that can implement memory and specialized functions. This makes the device suitable for datapath applications that require both distributed control logic and local data storage. The SRAM-based configuration is in-system programmable and typically loads from an external configuration device such as an EPC-series PROM at power-up. Typical applications include networking and communications equipment, industrial control panels, test and measurement systems, consumer audio/video bridging, and IoT sensor aggregation. The device is chosen when an engineer needs a moderate amount of programmable logic, many general-purpose I/O pins, and predictable low-cost performance on a 2.5 V design. A key design consideration is that the FPGA configuration is volatile: the bitstream must be loaded from external memory or a download cable after every power-up. Designers must also add adequate power-supply decoupling and carefully manage the FPGA configuration pins such as DCLK and CONF_DONE during board bring-up. This page synthesizes distributor pricing, ACEX 1K drop-in alternatives, practical design notes, and procurement guidance that are not normally listed together on a single manufacturer datasheet page.

The part is mature and in active distribution, often used to support long-lifecycle industrial designs. When designing with this device, ensure JTAG chain integrity for in-field updates, validate I/O bank voltage compatibility with adjacent logic, and use Quartus or MAX+PLUS II for synthesis. Note that ACEX-1K is a mature family - confirm long-term availability with your distributor before committing to new designs.
EP1K30FC256-3N - ACEX 1K FPGA, 30K Gates, 256-BGA | Intel
The Intel (formerly Altera) EP1K30FC256-3N is a member of the ACEX 1K family of low-cost SRAM-based FPGAs fabricated on a 0.22 µm CMOS process, integrating 30,000 typical gates (17,288 logic elements / 1,728 cells) into a 256-ball FineLine BGA (FBGA-256) package with 171 user I/Os. It operates from a 2.5 V core supply (2.375 V–2.625 V) and supports up to 24,576 RAM bits of embedded array memory distributed across 216 Logic Array Blocks (LABs), with system performance up to 200 MHz. An FPGA (Field-Programmable Gate Array) is a semiconductor device built from an array of configurable logic blocks (CLBs/LABs), programmable interconnect, and I/O cells that engineers can re-program in-system to implement arbitrary digital logic. ACEX 1K belongs to the broader programmable logic family hierarchy: FPGA → programmable logic device (PLD) → logic IC → integrated circuit. ACEX 1K positioned itself as a 'system-on-a-programmable-chip' (SOPC) platform, combining logic, embedded memory, and dual-port RAM in a single device for glue-logic and low-volume ASIC replacement. Key features of the EP1K30FC256-3N include the enhanced embedded array for implementing megafunctions such as efficient memory and specialized logic functions, dual-port RAM support, dedicated carry and cascade chains for high-performance arithmetic, JTAG-compliant boundary-scan testing per IEEE Std 1149.1, and 4-input look-up tables (LUTs) per logic element. The '3' speed grade offers typical propagation delays around 0.6 ns in the fastest paths. Architecturally, the EP1K30FC256-3N combines a 'FastTrack' continuous interconnect fabric with a distributed embedded array that can be configured as ROM, RAM, dual-port RAM, or first-in-first-out (FIFO) buffers. The device is configured via a serial or parallel configuration scheme using an Altera configuration EPROM or controller, supporting in-system programmability (ISP) through JTAG. Typical applications include digital signal processing glue logic, telecommunications interface bridging, peripheral bus expansion in PCI and embedded CPU systems, and industrial control logic where low unit cost, deterministic timing, and on-board reprogrammability outweigh the need for high logic density. The 171 user I/Os accommodate parallel buses, memory interfaces, and high-pin-count glue logic. When designing with the EP1K30FC256-3N, pay attention to multi-voltage I/O bank planning — the ACEX 1K family supports mixed-voltage interfacing on designated banks via VCCIO pins. Adequate decoupling (0.1 µF + bulk) and a solid ground pour are essential because the 256-ball BGA package relies on inner-plane thermal dissipation rather than a top-side heat spreader. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes beyond the manufacturer datasheet, giving an engineer a complete purchase and migration reference for the ACEX 1K 30K-gate class.
EP1K30FC256-3NAA - ACEX-1K FPGA, 30K Gate, 171 I/O | Intel
The Intel EP1K30FC256-3NAA is an ACEX-1K Field Programmable Gate Array (FPGA) with 1728 logic elements, approximately 30000 system gates, 24576 RAM bits, and 171 user I/Os, supplied in a 256-ball FBGA package. It runs from a 2.5 V core supply and is built on a 0.22 um SRAM-based process. The -3 speed ordering code supports 200 MHz class internal operation according to Arrow Electronics parametric data. An FPGA is a semiconductor logic device whose internal architecture can be configured after manufacturing. Unlike a fixed ASIC, an FPGA contains programmable look-up tables, register elements, and routing fabrics that are loaded from external configuration memory every time the part powers up. The ACEX-1K family belongs to the high-density programmable-logic hierarchy: FPGA -> programmable logic device -> embedded integrated circuit. It is commonly used where moderate logic density, parallel I/Os, and redesign flexibility are needed at system level. Key features of the EP1K30FC256-3NAA include 1728 logic elements for combinatorial and sequential logic, 171 parallel user I/Os that simplify bus interfaces and data acquisition systems, 24576 embedded RAM bits for small FIFOs and register files, and a 0.22 um 2.5 V architecture. The 256-ball FineLine BGA package provides a compact surface-mount footprint while maintaining adequate I/O count for card-edge or mezzanine systems. The ACEX-1K architecture implements logic in a matrix of LABs and uses embedded array blocks for memory. Being SRAM-based, the FPGA needs an external configuration device such as an EPC2 or a host processor to download a bitstream at power-up. The same-frame migration feature in ACEX-1K 256-ball packages allows different density grades to share a common BGA land pattern, easing design reuse across lower and higher density EP1K variants. Typical applications include industrial I/O glue logic, communication-protocol bridging, data-acquisition control, video timing and display interface logic, embedded processor bus bridges, and legacy FPGA replacement for boards using ACEX-1K devices. The 171 I/Os give enough channels for parallel peripherals, while the 2.5 V core lowers switching power compared with older 5 V FPGA families. A key design consideration is configuration management: because ACEX-1K has no nonvolatile internal flash, the designer must ensure the configuration source is reliable and that I/O pins are not actively driving before configuration is complete. Decoupling each VCC and VCCIO ball with a 0.1 uF ceramic capacitor is also required for stable high-speed operation. This page consolidates distributor stock status, pin-compatible ACEX-1K alternatives, ordering-code guidance, and practical board-level notes that are not all present in the original manufacturer datasheet. Pricing and availability are reported as of 2026-09-07 from public distributor listings.
EP1K30FI256-2 - 30K Gate ACEX-1K FPGA, 256-FBGA | Intel
The Intel (formerly Altera) EP1K30FI256-2 is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs) housed in a 256-ball Fine-pitch Ball Grid Array (FBGA) package. According to the verified web data, the device integrates 30,000 gates organized into 1,728 logic cells (1728 LEs) with 24,576 bits of embedded RAM and 171 user I/O pins. The -2 speed grade supports internal operation up to 200 MHz, fabricated on a 0.22 µm CMOS process with a 2.5 V core supply (2.375 V to 2.625 V tolerance). An FPGA (Field Programmable Gate Array) is a reprogrammable semiconductor device containing an array of configurable logic blocks (CLBs) interconnected by programmable routing, allowing designers to implement arbitrary digital logic, finite state machines, glue logic, DSP pipelines, and bus interfaces without fabricating a custom ASIC. The ACEX-1K family sits between traditional PLDs and high-density FPGAs, optimized for low-cost system-on-a-programmable-chip (SOPC) integration in a single device through enhanced embedded array structures implementing megafunctions such as efficient memory and specialized logic functions with dual-port RAM support. Key specifications of the EP1K30FI256-2 include 216 Logic Array Blocks (LABs), 171 user I/Os, 200 MHz maximum operating frequency, 2.5 V VCCINT core voltage, and an industrial operating temperature range of -40 °C to +85 °C. The device supports in-system programmability via JTAG, supports 5 V tolerant I/O with proper bank configuration, and is supported by the Quartus Prime design toolchain (legacy versions are required for ACEX-1K device family support). Architecturally, the ACEX-1K family uses an Enhanced Embedded Array structure that integrates embedded array blocks (EABs) for memory and dedicated logic functions, with each LAB containing 8 Logic Elements (LEs). The 200 MHz maximum frequency applies to internal register-to-register paths; I/O performance depends on the configured standard (LVTTL, LVCMOS, PCI, etc.). The 0.22 µm process provides a balance of density and static power that made the family attractive for cost-sensitive glue-logic and bus-interface applications at its introduction. Typical applications include bus bridging (e.g., PCI to local bus glue), industrial control logic, communication backplane glue logic, low-cost ASIC replacement, and peripheral interface integration. Designers should verify Quartus software version compatibility with the ACEX-1K family, as the family is end-of-life; current Intel FPGA development targets Cyclone, Arria, and Stratix families. When designing with this device, note that the EP1K30FI256-2 lacks modern features such as hard memory controllers, transceivers, and DSP blocks. Verify that the JTAG chain and configuration scheme (e.g., EPC2 configuration device) are supported by your manufacturing test environment before committing to production.
EP1K30FI256-2N - 30K Gate ACEX-1K FPGA, 256-BGA | Intel / Altera
The Intel (formerly Altera) EP1K30FI256-2N is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs), integrating 30,000 typical gates, 1,728 logic elements (LEs), and 24,576 RAM bits in a 256-ball FineLine BGA package. The device is fabricated on a 0.22 µm CMOS process, operates from a 2.5 V core supply, and supports user I/O counts up to 171 pins. The "-2N" suffix indicates an industrial temperature grade device with a speed grade of -2, optimized for medium-performance logic designs. An FPGA (Field Programmable Gate Array) is a type of programmable logic device that combines a matrix of configurable logic blocks (CLBs), programmable interconnect, and I/O cells on a single silicon die. FPGAs occupy the top of the programmable logic taxonomy: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit -> semiconductor. ACEX-1K specifically targets low-cost system-on-a-programmable-chip (SOPC) integration, allowing designers to implement embedded memory blocks, megafunctions, and DSP-style logic on one device, supplanting discrete logic ICs in many cost-sensitive designs. Key features of the EP1K30FI256-2N include dual-port embedded array blocks (EABs) for efficient memory and specialized logic functions, an enhanced embedded array architecture, in-system programmability via IEEE 1149.1 JTAG, and a maximum internal operating frequency of 200 MHz. The 256-ball FineLine BGA package offers a compact footprint suitable for high-density boards while providing ample I/O for parallel buses, memory interfaces, and high-speed glue logic. Typical applications span glue logic replacement, interface bridging, custom peripheral controllers, industrial control subsystems, and low-cost ASIC prototyping. The combination of dual-port EAB memory, 171 user I/Os, and a 2.5 V core makes it well suited to designs requiring moderate logic density and on-chip RAM without migrating to higher-cost Cyclone or Arria families. When designing with this device, verify that the Quartus toolchain version supports the ACEX-1K family and that the board-level decoupling scheme supplies clean 2.5 V to the core. Since ACEX-1K is a legacy family, plan for long-term availability risk by validating second sources before committing to high-volume production.
EP1K30QC208-1 - 30K Gates ACEX-1K FPGA, 208-PQFP | Intel (Altera)
The Intel (formerly Altera) EP1K30QC208-1 is a 30,000-gate field-programmable gate array from the ACEX-1K family, housed in a 208-pin Plastic Quad Flat Pack (PQFP / 208-BFQFP) package with a 0.500 mm terminal pitch. According to the ACEX-1K datasheet family, the device integrates 1,728 logic elements (LEs), 216 logic array blocks (LABs), 24,576 bits of embedded SRAM, and 147 programmable user I/O pins, all operating from a 2.5 V core supply (2.375 V to 2.625 V). A field-programmable gate array (FPGA) is a reconfigurable semiconductor device built from an array of programmable logic blocks, programmable interconnect, and configurable I/O cells. Within the broader taxonomy it sits under programmable logic (PLD) -> programmable logic IC -> digital logic IC -> integrated circuit -> semiconductor. FPGAs enable hardware-level parallelism and in-system reprogrammability, distinguishing them from fixed-function ASICs and from low-density SPLDs/CPLDs. Key features of the EP1K30QC208-1 include a maximum operating frequency quoted around 250 MHz in the ACEX-1K family, in-system programmability via SRAM configuration cells, embedded array blocks (EABs) for efficient memory and DSP-style functions, dual-port RAM support, JTAG (IEEE 1149.1) boundary-scan test, and multi-volt I/O supporting 2.5 V and 3.3 V interfaces. The architecture is built on a 2.5 V CMOS process for low power dissipation relative to legacy 5 V FPGA families. Typical applications include glue-logic consolidation, bus-bridging and protocol-translation interfaces, low-density digital signal processing pre-processing, industrial control boards, telecom line-card glue logic, and cost-sensitive prototyping where a hard ASIC is not yet justified. The wide 0 to 70 °C commercial temperature grade suits office, lab, and factory-floor environments. When designing with this part, note that ACEX-1K FPGAs are volatile and require configuration at every power-up; plan a configuration PROM (EPC2/EPC4/EPC8) or microcontroller host. Use the Quartus II (or legacy MAX+PLUS II) toolchain for synthesis, place-and-route, and bitstream generation. Because the PQFP package has relatively long leads, apply standard PQFP PCB layout guidelines - ground plane, decoupling, and short-trace fanout - to meet signal-integrity budgets above 100 MHz.
EP1K30QC208-1N - 30K-Gate ACEX 1K FPGA | Altera
The Altera EP1K30QC208-1N is an ACEX 1K family field-programmable gate array (FPGA) that provides 30,000 typical gates, 1,728 logic elements, 24,576 RAM bits and 147 user I/O pins, with a maximum internal frequency of 250 MHz on a 2.5 V core. It is offered in a 208-pin PQFP/BFQFP surface-mount package with a commercial temperature grade and lead-free ('N') finish. An FPGA is a reconfigurable digital integrated circuit built from programmable logic blocks, memory resources and routing switches that users configure after manufacture by downloading a bitstream. In the product hierarchy, the EP1K30QC208-1N is an ACEX 1K FPGA -> field-programmable gate array -> programmable logic device (PLD) -> integrated circuit. Unlike ASICs, FPGAs allow in-system firmware changes, shorter prototyping cycles and low-volume deployment without custom mask costs. The ACEX 1K family is optimized for cost-sensitive system-on-a-programmable-chip (SOPC) integration, combining logic with embedded memory blocks in a single 2.5 V device. Feature summary includes: 30,000 typical system gates; 1,728 logic elements arranged in 216 LABs; 24,576 RAM bits; 147 I/O pins; 250 MHz internal toggle frequency; 0.22 um process technology. The embedded array can implement dual-port RAM, ROM or FIFO functions, while the logic array handles general-purpose registers and counters. The 208-pin PQFP package balances board area with usable I/O, and the commercial temperature grade makes it suitable for indoor equipment. The suffix 'N' signals a lead-free finish, which supports RoHS-oriented assembly flows. The ACEX 1K architecture separates logic and memory into dedicated blocks, allowing megafunctions such as dual-port RAM or specialized logic to be implemented without consuming lookup-table resources. Because the memory array is embedded on-chip, external SRAM is not necessary for many buffer functions. The 2.5 V core reduces dynamic power versus earlier 5 V and 3.3 V PLDs, while the 0.22 um CMOS process enables 250 MHz internal performance. Configuration data is held in SRAM cells, so the FPGA must be loaded after power-up, typically from a configuration device, host processor or passive serial source. Typical applications include cost-sensitive SOPC designs, I/O expansion and bus-bridge functions in communication and industrial equipment, and custom timing/control engines that need parallel I/O. With 147 user I/O pins, this device can interface to 32-bit microprocessors, ADCs/DACs, displays and legacy backplanes. Its memory blocks can serve as FIFOs for data buffering without adding external RAM. Designers must provide decoupling on the 2.5 V core rail, complete the FPGA configuration circuit before releasing the device from reset, and verify I/O bank compatibility against signals at other voltages. Because configuration memory is volatile, a configuration source is mandatory in every production design.

ACEX 1K was positioned for low-cost system-on-a-programmable-chip (SOPC) integration, combining logic array blocks (LABs) with an enhanced embedded array that can implement memory and specialized logic functions. The QC208 version is a 208-lead plastic quad flat package with gull-wing terminals and a square body, commonly used on boards that do not need the density of a ball-grid array. Key features of this -2 speed-grade part include 216 LABs, 1,728 logic elements, 24,576 RAM bits, 147 user I/O pins, and 6 dedicated inputs. The 2.5 V CMOS architecture keeps core power low for its era, while the 208-terminal form factor provides ample routing access for moderate pin-count designs. The commercial operating range is 0 C to 70 C, which suits equipment installed indoors in industrial, communications, or instrumentation environments. The -2 speed grade sits between faster -1 and slower -3 family options, giving designers a balanced timing-versus-cost choice. Technically, the EP1K30QC208-2 is an SRAM-based FPGA: its configuration is loaded at power-up and is lost when power is removed unless an external configuration device or JTAG host is used. The ACEX 1K embedded array in the family datasheet literature supports dual-port RAM and specialized logic megafunctions, which helps designers implement FIFOs, small buffers, and state machines without external memory devices. Within the ACEX 1K hierarchy, the EP1K30 offers mid-density resources and is often paired with companion ACEX devices when a design must be migrated to a smaller or larger density. Typical applications include industrial controller glue logic, communication interface buffering, video timing and imaging logic, test-and-measurement data formatting, and legacy board repair. In each of these, the available I/O and internal RAM reduce the number of external logic and FIFO chips. The 2.5 V core rail should be generated from a clean low-noise supply, and I/O voltage levels should be checked before connecting to 3.3 V or 5 V peripherals. A key design consideration is the configuration source. Because ACEX 1K does not retain its program when unpowered, the PCB should include a configuration device or provide JTAG access so the FPGA can be reprogrammed at every power-up. For thermal and mechanical design, the 208-pin PQFP has a 0.5 mm terminal pitch; use a well-ventilated layout and follow the package land pattern. This page synthesizes distributor pricing, available package-compatible alternatives, and practical design guidance not found in the manufacturer datasheet alone. It is intended to help engineers quickly evaluate EP1K30QC208-2 for legacy BOM replacement, reverse engineering, and maintenance of ACEX 1K-based systems.
EP1K30QC208-2N - 30K Gate ACEX 1K FPGA, 208-PQFP | Intel
The Intel (formerly Altera) EP1K30QC208-2N is a member of the ACEX 1K family of low-cost SRAM-based FPGAs, delivering 30,000 typical gates, 1,728 logic elements (LEs) and 24,576 bits of embedded array memory in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. It is built on a 0.22 µm CMOS process with a 2.5 V core supply and operates at up to 200 MHz system performance, providing system-on-a-programmable-chip (SOPC) integration in a single device. An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) that combines the density of an ASIC with the flexibility of in-system reprogrammability. The ACEX 1K family specifically targets cost-sensitive glue-logic, bus-interface, and DSP-coprocessor applications. It sits within the broader hierarchy of programmable logic: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit (IC) -> semiconductor. Compared with CPLDs, FPGAs offer much higher logic density and embedded memory, at the cost of volatile configuration and slightly higher power. Key features of the EP1K30QC208-2N include 147 user I/O pins, 216 logic array blocks (LABs), embedded dual-port RAM, a dedicated Double Data Rate (DDR) interface option, and an enhanced embedded array for implementing megafunctions such as efficient memory and specialized logic functions. The 208-pin PQFP package supports easy board-level assembly for prototype and low-to-mid volume production, while the 2.5 V core and multi-voltage I/O bank support simplify interfacing with 3.3 V and 5 V peripherals. Architecturally, the EP1K30QC208-2N uses a Lookup-Table (LUT)-based logic element with 4-input combinational capability and a register, organized into LABs with carry-chain and cascade-chain interconnect. The 24 Kbit embedded system block (ESB) memory can be configured as dual-port RAM, ROM, FIFO or CAM, removing the need for external SRAM in many data-pipeline designs. Configuration is loaded from a serial PROM via the dedicated configuration interface. Typical applications include glue logic between microprocessors and peripherals, custom bus bridges (PCI to local bus), DSP coprocessors, industrial control and instrumentation front-ends, telecommunications line cards, and legacy system refresh projects where a programmable replacement is preferred to an ASIC redesign. Designers often pair it with EPC2 configuration PROMs from Intel/Altera for standalone boot. When designing with this device, ensure the 2.5 V VCCINT and VCCIO bank supplies are properly decoupled (one 0.1 µF and one 10 µF per pin group) and that the configuration clock and MSEL pins are set for the desired configuration mode (AS, PS or JTAG). Because ACEX 1K parts have been EOL for many years, engineers should verify long-term availability before committing the part to new designs. This page consolidates manufacturer specification data, real-time distributor pricing, drop-in alternative cross-references and practical design notes that go beyond the original Altera ACEX 1K datasheet, helping procurement, design and component-engineering teams evaluate the EP1K30QC208-2N and its modern replacements in a single view.
