EP1K30QC208-3 - ACEX-1K FPGA, 30K Gates, 208-PQFP | Intel
The Intel (formerly Altera) EP1K30QC208-3 is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs), featuring 30,000 typical gates and 1,728 logic elements housed in a 208-pin Plastic Quad Flat Pack (PQFP) surface-mount package. The "-3" speed grade designates the device's commercial timing class within the ACEX-1K family, balancing cost and performance for general-purpose logic integration. Operating from a 2.5 V core supply, the EP1K30QC208-3 delivers 147 user I/O pins with embedded array blocks (EABs) for dual-port RAM and ROM implementation. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the high-density integration of gate arrays with the design flexibility of in-system reprogrammability. FPGAs belong to the broader semiconductor hierarchy: programmable logic -> digital IC -> integrated circuit -> semiconductor. The ACEX-1K family specifically targets low-cost system-on-a-programmable-chip (SOPC) designs by embedding megafunctions such as efficient memory and specialized I/O structures alongside general-purpose logic. Key features include 24,576 RAM bits distributed across embedded array blocks, support for LVTTL, LVCMOS, and PCI I/O standards, in-system programmability via IEEE 1149.1 JTAG, and multi-volt I/O capability enabling bridging between 2.5 V, 3.3 V, and 5 V logic domains. The 208-pin PQFP package provides a low-cost, board-friendly footprint for volume production. The EP1K30QC208-3 uses a SRAM-based look-up table (LUT) architecture with embedded array blocks for distributed memory. Its 4-input LUTs deliver efficient combinational logic synthesis, while EABs provide dedicated dual-port RAM blocks for FIFOs, CAMs, and ROM functions. The -3 speed grade targets applications where deterministic logic performance is needed without paying for the faster -1 speed grade. Typical applications include glue logic replacement, bridge and protocol converters (e.g., PCI to local bus), industrial control and instrumentation front-ends, telecommunications line cards, and low-volume ASIC prototyping. The 147 available I/O pins make this device well-suited for parallel bus interfaces and multi-channel data acquisition front-ends. When designing with the EP1K30QC208-3, engineers must respect 2.5 V core supply sequencing and provide proper decoupling. The PQFP package also requires thermal consideration at sustained high toggle rates. ACEX-1K devices are programmed via the Quartus II design software or legacy MAX+PLUS II tools. Note: the ACEX-1K family is end-of-life per Intel (Altera) PCN; consider Cyclone or Cyclone II for new designs requiring ACEX-1K function. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers evaluate both new designs and legacy replacement scenarios.
EP1K30QC208-3N - ACEX-1K FPGA, 30K Gates, 208-PQFP | Altera
The Altera (now Intel) EP1K30QC208-3N is a member of the ACEX-1K family of Field-Programmable Gate Arrays (FPGAs) fabricated on a 0.18 µm CMOS process, offering 30,000 typical gates, 1,728 logic elements, and 147 user I/O pins housed in a 208-pin Plastic Quad Flat Pack (PQFP / 208-BQFP) package. It is a non-volatile, SRAM-look-up-table (LUT) based FPGA with embedded array blocks (EABs) intended for glue-logic, bus-interface, and mid-density glue replacement in telecom, industrial, and consumer designs. The "-3N" suffix denotes the speed grade (-3, fastest in the family) and an industrial operating temperature range with lead-free / Pb-free plating. A Field-Programmable Gate Array (FPGA) is a type of integrated circuit whose digital logic function is defined after manufacture by the end user through a configuration bitstream loaded into on-chip SRAM. FPGAs sit in the programmable-logic hierarchy alongside CPLDs and are commonly used as a flexible alternative to fixed-function ASICs for low- to mid-volume designs. Within the broader taxonomy, the ACEX-1K family belongs to low-cost, mid-density FPGAs -> programmable logic -> digital semiconductor -> integrated circuit. The EP1K30 specifically targets designs that need more than a CPLD but cannot justify a Cyclone or Stratix device. Key features include 1,728 logic elements organized into 172 logic array blocks (LABs), 6 embedded array blocks (EABs) providing up to 24 Kbits of dual-port RAM, support for LVTTL, LVCMOS, PCI, SSTL-2, and other I/O standards, and a JTAG (IEEE 1149.1) interface for boundary-scan test and in-system programming. The device supports configuration via configuration EPROM, JTAG, or microprocessor-controlled serial/parallel modes, and is supported by the legacy Altera MAX+PLUS II and Quartus design software toolchains. Typical applications include telecommunications line cards, industrial control and instrumentation, network routers and switches, glue-logic replacement, and bus-bridging interfaces (PCI, ISA, VME). The wide 24,576-bit on-chip memory (from 6 EABs) is also useful for FIFO buffers, lookup tables, and small dual-port memory blocks. Because the part is in active last-time-buy / mature status, current production use is dominated by long-lifecycle industrial, medical, and aerospace programs where redesign is impractical. When designing with this device, observe the I/O bank supply (VCCIO) and core supply (VCCINT) requirements, provide proper decoupling on every supply pin, and respect the 5 V tolerance boundary when interfacing to legacy 5 V logic. The PQFP-208 package requires careful PCB layout for high-speed signals due to its leaded, longer-trace format compared with BGA alternatives.

EP1K30QI208-2 - ACEX-1K FPGA 2.5V 208PQFP | Altera
The Altera EP1K30QI208-2 is an ACEX-1K field-programmable gate array (FPGA) with 30,000 typical gates, 1,728 logic cells, 24,576 RAM bits, and 147 user I/Os. It is supplied in a 208-lead PQFP/BFQFP surface-mount package, uses a 2.5 V core, and carries the QI208-2 ordering code: Q = PQFP package, I = industrial grade, 208 pins, speed grade -2. DigiKey and AiPCBA listings identify it as an ACEX-1K 2.5 V programmable logic device. An FPGA is a semiconductor device whose logic fabric is configured after manufacturing using hardware description languages rather than being fixed at the factory. FPGAs belong to the programmable logic device hierarchy and sit above simple PLDs and CPLDs in logic capacity, while remaining lower-cost and more flexible than custom ASICs for moderate-volume designs. The ACEX-1K family is an early 2.5 V FPGA line intended for low-cost system-on-a-programmable-chip integration, making the EP1K30QI208-2 useful for legacy industrial control, communications bridging, and test-and-measurement boards that need reconfigurable parallel logic. Key features of the EP1K30QI208-2 include 147 user I/O pins, which allow it to interface with a wide range of external buses, SRAM-like parts, and processors. Its 24,576 embedded RAM bits provide on-chip FIFO or small buffer memory, reducing the need for external SRAM in simpler designs. The 2.5 V core reduces power consumption compared with older 5 V or 3.3 V programmable devices. The industrial-grade temperature option extends reliable operation into factory, instrumentation, and outdoor enclosure applications. An enhanced embedded array supports megafunctions such as memory and specialized logic functions, while dual-port memory support enables efficient data buffering. Architecturally, the ACEX-1K series uses LE-based logic with look-up-table implementation and an embedded array for memory and complex functions. The DigChip device-family summary describes dual-port capability and an embedded array intended for system-on-a-programmable-chip integration. With a reported 200 MHz family maximum in the AiPCBA summary and speed-grade option -2, the EP1K30QI208-2 is adequate for bus-level glue logic, state machines, and moderate-rate data path functions rather than ultra-high-speed transceiver applications. Typical applications include legacy PLC I/O expansion, protocol bridging in networking equipment, imaging preprocessing, medical instrument logic, and teaching-laboratory FPGA designs. Because it is an older 2.5 V FPGA, system designers must include a separate 2.5 V supply and a configuration source, since FPGA configuration is not retained when power is removed. One important design consideration is that the EP1K30QI208-2 is configuration-based and requires a configuration device, download cable, or host processor at every power-up. It does not behave like a CPLD that is instantly active. Also, exact VCCIO and thermal specifications should be confirmed from the manufacturer datasheet before committing the PCB layout. This page synthesizes distributor availability, ACEX-1K family alternatives, and practical selection guidance from multiple web sources, giving engineers a quicker starting point than searching datasheets and supplier pages separately.
EP1K30QI208-2N - 30K-Gate ACEX 1K FPGA, 147 I/O, 208-PQFP | Intel
The Intel (Altera) EP1K30QI208-2N is a member of the ACEX 1K family of FPGAs, fabricated on a 0.22 um CMOS process with a 2.5 V core supply, integrating 30K typical gates, 1728 logic elements, and 24576 bits of embedded RAM in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) surface-mount package with 147 user I/O pins. It is organized as 216 Logic Array Blocks (LABs) and supports a maximum internal clock frequency of 200 MHz, delivering a low-cost system-on-a-programmable-chip (SOPC) integration path for volume applications. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs), programmable routing channels, and programmable I/O cells that allow the hardware function to be defined after manufacturing. FPGAs sit in the programmable-logic tier of the digital-logic hierarchy, above fixed-function ASICs and below microcontrollers in flexibility, and are widely used for glue logic, bus bridging, DSP datapaths, and prototyping of ASIC designs. The ACEX 1K family specifically targets high-volume, cost-sensitive applications that previously would have required gate-array or standard-cell ASICs. Key features of the EP1K30QI208-2N include 1728 logic elements organized into a 4-input LUT-based fabric, 24576 bits of embedded dual-port RAM distributed across nine Embedded Array Blocks (EABs), six Clock Lock Loops (PLLs) for clock conditioning, and JTAG-compliant IEEE 1149.1 boundary-scan support. The 'Q' in the part number indicates the PQFP package style, 'I' indicates the Industrial temperature grade (-40C to +85C), '208' is the pin count, and the speed grade '-2N' places it in the mid-speed tier of the ACEX 1K family. The device architecture uses a hierarchical interconnect with FastTrack continuous routing channels, providing predictable timing and fast compile times in the legacy MAX+PLUS II and Quartus design flows. Per-row dual-port EABs allow efficient implementation of RAM, ROM, FIFO, and multiplier megafunctions without sacrificing logic capacity. Typical applications include industrial control glue logic, telecommunication line-card interfaces, low-cost prototyping bridges, and bus-interface conversion where the 147 user I/Os and the industrial temperature range are sufficient. The wide I/O count supports parallel buses, video pixel interfaces, and multi-channel peripheral aggregation in a single chip. When designing with this part, verify power sequencing on the 2.5 V VCCINT and 3.3 V VCCIO rails, provide bulk decoupling at every supply pin, and confirm that the chosen speed grade closes timing on the longest combinational path. Designers migrating to the EP1K30QI208-2N from a smaller ACEX 1K device should re-check the I/O bank assignments because the 208-pin PQFP offers the largest I/O count of the family. This page synthesizes distributor pricing, verified same-package drop-in alternatives in the same ACEX 1K family, and practical design notes that go beyond the manufacturer datasheet's nominal specifications.
EP1K30QI208-3N - 30K Gate ACEX 1K FPGA, 147 I/O, 208-PQFP | Intel (Altera)
The Intel (formerly Altera) EP1K30QI208-3N is a member of the ACEX 1K family of Field-Programmable Gate Arrays (FPGAs), delivering approximately 30,000 typical ASIC gates and 1,728 logic elements in a 208-pin Plastic Quad Flat Pack (PQFP) package. Operating from a 2.5 V core supply (2.375 V min / 2.625 V max), the device exposes 147 user I/O pins with 6 dedicated inputs, giving designers substantial signal headroom for glue logic, bus interfacing, and state-machine consolidation around a host processor. An FPGA (Field-Programmable Gate Array) is a programmable logic device that combines the integration density of a gate array with the flexibility of in-system reprogrammability. ACEX 1K sits in the low-to-mid density FPGA tier, positioned between simple CPLDs and high-density SRAM-based FPGAs, and is widely used for interface bridging, custom peripheral expansion, and DSP pre-processing on cost-sensitive industrial boards. The -3N speed grade and industrial temperature rating (-40 °C to +85 °C) target factory automation, telecom peripherals, and long-life industrial equipment. Key features include 24,576 RAM bits, 6 Embedded Array Blocks, dual LVTTL/LVCMOS I/O support, JTAG-based in-system programmability via the IEEE 1149.1 boundary-scan chain, and on-chip clock-management PLLs that simplify multi-clock designs. The 208-pin PQFP package with 0.5 mm pitch is a through-hole-friendly plastic package suitable for socketed prototypes and lower-density production runs where BGA rework costs are unacceptable. Architecturally, ACEX 1K devices embed logic array blocks (LABs) backed by continuous SRAM configuration memory, which is loaded at power-up from a serial configuration EPROM such as the EPC2 or EPC8. This volatile configuration model makes the EP1K30QI208-3N ideal for designs where configuration flexibility, fast prototyping, and iterative revision outweigh the need for non-volatility. MultiVolt I/O allows 3.3 V, 2.5 V, and 1.8 V interfacing without external level shifters. Typical applications include industrial PLC interface cards, telecom line-card glue logic, medical instrument front-panel controllers, legacy parallel-bus bridges, and compact PCI peripheral controllers. The wide operating voltage tolerance and rugged PQFP package also make it a popular retro-fit for older Altera designs that are being re-spun onto current revision hardware without a layout re-spin. When designing with this device, remember that the configuration is volatile - a boot PROM or microcontroller is mandatory. The 0.5 mm PQFP pitch can be hand-soldered with a fine-tip iron, but production assembly requires careful solder-paste stencil design and bottom-side preheat profiling to avoid tombstoning the fine-pitch leads. This page synthesizes distributor stock levels, ACEX 1K family cross-references, drop-in pin-compatible alternatives, and practical layout guidance not found in the original datasheet - useful both for new designs and for sustaining older industrial systems that depend on this long-life part.

The Altera (Intel) EP1K30TC144-1 is a member of the ACEX-1K family of 2.5 V CMOS Field Programmable Gate Arrays, providing 30,000 equivalent gates, 1,728 logic elements, 216 Logic Array Blocks (LABs), 24,576 bits of embedded RAM, and 102 user I/Os in a 144-pin LQFP (TQFP) package. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows designers to implement custom digital logic, memory blocks, and dedicated I/O functions in a single IC after manufacturing. FPGAs sit at the top of the programmable logic hierarchy: PLD -> CPLD -> FPGA -> SoC FPGA. The ACEX-1K family specifically targets low-cost system-on-a-programmable-chip (SOPC) integration, combining look-up-table (LUT)-based logic with dual-port embedded array blocks (EABs) that can be configured as memory or specialized logic functions. Key features of the EP1K30TC144-1 include 30,000 typical gates, 1,728 logic elements (cells), 24,576 total RAM bits, 216 LABs, and 102 maximum user I/O pins. The device operates from a 2.5 V core supply and supports in-system programmability via SRAM configuration memory. The -1 speed grade corresponds to the slowest of the three available ACEX-1K speed bins, trading timing margin for lower price. Architecturally, the EP1K30TC144-1 uses a continuous, hierarchical interconnect structure of fast row and column channels that route signals between LABs and embedded array blocks (EABs). Each EAB provides up to 4,096 bits of RAM that can be used for true dual-port, simple dual-port, or single-port memory, supporting megafunctions such as FIFOs, ROM, and CAM. The LUT-based LE delivers predictable 4-input combinational logic plus a dedicated carry chain for efficient arithmetic. Typical applications include glue logic replacement, low-volume ASIC prototyping, industrial control interfaces, communication bridges, and embedded control subsystems where the 30K-gate density and 102 I/Os offer an attractive balance between capability and cost. The 144-LQFP package is also convenient for hand-solderable prototyping or production runs where BGA handling infrastructure is not required. When designing with this part, note that ACEX-1K devices are SRAM-based and require a configuration ROM or microcontroller to load the bitstream at every power-up. The 144-LQFP package has limited thermal headroom compared to BGA variants, so high-toggle-rate designs should evaluate junction temperature against the package's theta_JA. This page synthesizes distributor pricing from 19+ sources, same-brand Altera drop-in alternatives in the same 144-LQFP footprint, and practical design notes not consolidated in the manufacturer datasheet, delivering decision-ready information for sourcing and engineering teams.

This page synthesizes distributor pricing, drop-in alternatives from the Altera/Intel ACEX-1K family and cross-brand equivalents, JTAG configuration guidance, and practical design notes not found in a single manufacturer datasheet — useful for engineers maintaining legacy ACEX-1K designs or planning obsolescence migrations.
EP1K30TC144-2 - 30K Gate ACEX 1K FPGA, 144-TQFP | Intel
The Intel EP1K30TC144-2 is a member of the ACEX 1K family of Field Programmable Gate Arrays (FPGAs) with 30,000 system gates, 1,728 logic cells, 216 logic array blocks (LABs), and 102 user I/Os, housed in a 144-pin TQFP package. Built on a 0.22 µm SRAM-lookup-table (LUT) architecture operating from a 2.5 V core supply, this device delivers up to 200 MHz internal performance in a low-cost, single-chip programmable logic solution. A Field Programmable Gate Array (FPGA) is a reconfigurable semiconductor device whose logic fabric, routing, and I/O cells are defined by a user-supplied bitstream rather than at the wafer fab. FPGAs sit at the top of the programmable logic hierarchy (PAL -> CPLD -> FPGA) and combine coarse-grained logic blocks, distributed SRAM, and dedicated DSP/memory blocks, allowing one silicon device to emulate anything from a glue-logic bridge to a complete processor subsystem. ACEX 1K is the entry-level low-cost FPGA family from Intel (formerly Altera), positioned between simple CPLDs and high-density Cyclone-series devices, and it implements each logic element as a 4-input LUT with dedicated carry chain. Key features of the EP1K30TC144-2 include dual-port embedded array blocks (EABs) that can be configured as ROM, single-port RAM, dual-port RAM, or FIFO without consuming logic resources, in-circuit reconfigurability via the passive serial configuration scheme, support for LVTTL, LVCMOS, and PCI I/O standards, and JTAG boundary-scan testability compliant with IEEE 1149.1. The "-2" speed grade corresponds to the faster of the two commercial speed grades offered for this family, and the "TC" package code designates a 144-pin Thin Quad Flat Pack (TQFP) with commercial temperature grading. From a system-design perspective, the EP1K30TC144-2 architecture combines a continuous interconnect network with predictable routing delays, allowing timing closure on legacy 5 V and 3.3 V boards. Embedded array blocks (EABs) provide dedicated dual-port SRAM up to 16 Kbits each, suitable for small FIFOs and register files. The device supports in-system programming through JTAG or a serial configuration PROM (EPC1/EPC2 family), making it a flexible prototype-to-production bridge. Typical applications include bridge and glue logic between microprocessors and peripherals, custom I/O expansion for microcontrollers and DSPs, low-volume prototyping of digital designs, industrial control and instrumentation front-ends, and legacy system re-implementation where pin-compatible, low-density FPGAs are required to replace discrete TTL/CMOS logic. When designing with the EP1K30TC144-2, designers must observe the 2.5 V VCCINT requirement and use of level-translation buffers if interfacing with 3.3 V or 5 V logic, although the I/O banks natively support LVTTL/LVCMOS signalling. Bitstream storage in an external PROM or flash is mandatory because the SRAM-based configuration memory is volatile. This page synthesizes ACEX 1K family datasheet parameters, drop-in compatible Intel/Altera variants from the same TC144 footprint, and practical design notes not found in the standalone datasheet PDF.

The Intel / Altera EP1K30TC144-2N is a member of the ACEX-1K FPGA family delivering 30,000 system gates, 1,728 logic elements, and 24,576 RAM bits in a 144-pin TQFP (20x20 mm) package. It is fabricated on a 0.22 µm EEPROM-based process and operates from a 2.5 V core supply (2.375 V to 2.625 V) with multi-standard I/O support. The device provides 102 user I/O pins and 216 logic array blocks (LABs), targeting low-cost system-on-a-programmable-chip (SOPC) integration with embedded array blocks (EABs) for efficient memory and DSP megafunctions. An FPGA (Field-Programmable Gate Array) is a reprogrammable semiconductor device built from an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells. FPGAs sit within the broader hierarchy of programmable logic devices (PLDs) -> complex programmable logic devices (CPLDs) -> FPGAs -> SoC FPGAs, occupying the mid-to-high density tier for glue logic, parallel processing, and prototype ASIC replacement. The ACEX-1K family in particular introduced an enhanced embedded array architecture that combined look-up-table logic with dedicated dual-port memory blocks, enabling megafunctions such as FIFO buffers, DSP multipliers, and CPU cores within a single chip. Key features of the EP1K30TC144-2N include 6 EABs delivering up to 24,576 bits of dual-port RAM, four phase-locked loops (PLLs) for clock management, in-system programmability via IEEE 1149.1 JTAG, and multi-voltage I/O support including 3.3 V, 2.5 V, and 1.8 V interfacing. The device supports configuration through Altera's serial configuration devices, passive serial, or JTAG modes. The -2 speed grade denotes a specific Fmax performance bin (~180 MHz internal), while the N suffix indicates lead-free (Pb-free) packaging per RoHS directive compliance. Architecture-wise, the ACEX-1K family uses a continuous, hierarchical interconnect structure (FastTrack) that provides predictable timing across the device, and each LAB contains 10 logic elements with 4 inputs each. The four PLLs enable on-chip clock multiplication, division, phase shifting, and duty-cycle control, eliminating external clock-management chips in many designs. The 0.22 µm process yields a typical quiescent current below 50 mA at full operation. Typical applications include telecommunications line-card glue logic, industrial control and motor drive interfaces, prototype ASIC replacement, low-density DSP co-processing, peripheral bridging (PCI to local bus, UART expansion), and legacy system maintenance where a discontinued ASIC must be replaced without a full PCB redesign. The 144-TQFP footprint simplifies hand-soldering and rework compared to BGA alternatives, making the EP1K30TC144-2N attractive for low-volume production, field upgrades, and educational platforms. When designing with this device, ensure the configuration PROM is correctly sized for the compressed or uncompressed bitstream and that the 2.5 V rail is decoupled with 0.1 µF and 10 µF capacitors close to the VCCINT pins. Designers migrating to newer Altera/Intel families (Cyclone, MAX II) should treat the EP1K30TC144-2N as a long-term availability part via the Altera Mature Products program rather than a new-design platform. This page synthesizes distributor availability, lead-time intelligence, and same-family drop-in alternatives for engineers maintaining legacy ACEX-1K designs, complementing the original datasheet with practical sourcing guidance.

The Intel (formerly Altera) EP1K30TC144-3 is a member of the ACEX-1K programmable logic device family that delivers 30,000 typical gates (with up to 56,000 maximum system gates) in a 144-pin LQFP (TQFP) surface-mount package, integrating 1,728 logic elements and 24,576 RAM bits. The "-3" speed grade designates the slowest of three speed bins offered for the EP1K30 family, with internal core logic running at up to 200 MHz on the 0.22 µm SRAM-based architecture. The device exposes 102 user I/O pins through four I/O banks compatible with 2.5 V LVCMOS/LVTTL signaling, plus eight global clock networks and six dedicated clock pins. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnect, and configurable I/O cells that can be re-programmed after manufacture to implement custom digital logic. FPGAs sit within the broader hierarchy of programmable logic devices (PLDs) -> complex programmable logic devices (CPLDs) -> FPGAs -> programmable SoCs, and are widely used as glue logic, prototyping vehicles, and low-volume custom compute engines. Key features of the EP1K30TC144-3 include 216 Logic Array Blocks (LABs) each containing 8 logic elements, dual-port embedded array blocks (EABs) usable as RAM or ROM with up to 24 Kbits total, JTAG-compliant IEEE 1149.1 boundary-scan test support, in-system programmability via the serial configuration device interface, and MultiVolt I/O that permits mixed-voltage interfacing with 2.5 V, 3.3 V, and 5.0 V peripherals through bank-by-bank reference voltages. The architecture combines a fine-grained enhanced embedded array (suitable for memory, multipliers, and DSP megafunctions) with a coarse-grained logic array for general glue logic, all wired through a continuous FastTrack interconnect. The 2.5 V core supply combined with MultiVolt I/O banks allows the device to operate as a low-power bridge between modern 2.5 V ASICs and legacy 5 V buses, simplifying mixed-voltage board designs. Typical applications for the EP1K30TC144-3 include glue logic and bus bridging for PCI/ISA peripherals, custom DSP pre-processing for audio and video pipelines, low-volume communication protocol controllers (UART, SPI, I2C bridges, HDLC), industrial control and instrumentation front-ends, and legacy system refresh projects where engineers migrate discrete 74-series logic or small CPLDs into a single re-programmable device. The 144-LQFP package makes it convenient for hand-prototyping and rework-friendly assembly on 1.6 mm pitch headers. When designing with the EP1K30TC144-3, remember that configuration data must be loaded at every power-up from a serial configuration device such as the EPC2 or EPC8, since the SRAM-based fabric is volatile. Decoupling should follow the Quartus II pin planner recommendation of at least one 0.1 µF and one 10 µF capacitor per supply pin group.

The Intel / Altera EP1K30TC144-3N is a member of the ACEX-1K® family of Field Programmable Gate Arrays (FPGAs) that integrates 30,000 typical gates, 1,728 logic elements, and 24,576 RAM bits in a single low-cost device. Housed in a 144-pin LQFP (Low-profile Quad Flat Pack) package with 102 user I/O pins, it provides a system-on-a-programmable-chip (SOPC) solution fabricated on a 0.22 µm SRAM-based CMOS process and operating from a 2.5 V core supply at up to 200 MHz internal performance. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and I/O cells, all of which can be redefined after manufacturing to implement arbitrary digital logic. FPGAs sit in the programmable logic hierarchy between CPLDs (smaller, non-volatile, lower density) and ASICs (fixed-function, highest density). ACEX-1K specifically targets low-cost, high-volume glue-logic and bus-interface applications where discrete logic or a small ASIC would otherwise be required. Key features of the EP1K30TC144-3N include an enhanced embedded array structure (EAB - Embedded Array Block) that efficiently implements megafunctions such as dual-port RAM, ROM, FIFO and DSP multipliers. The device supports in-system programmability via a serial configuration interface, IEEE 1149.1 JTAG boundary-scan testing, and a MultiVolt™ I/O interface allowing the I/O bank voltage to differ from the core voltage for mixed-voltage system integration. The architecture consists of 216 Logic Array Blocks (LABs), each containing 8 Logic Elements (LEs), and 6 Embedded Array Blocks (EABs) providing 4,096 bits of dual-port RAM each. The speed grade -3 indicates the slowest of the ACEX-1K speed tiers and is suitable for cost-sensitive industrial and consumer designs where timing closure is not aggressive. Typical applications include glue-logic replacement, bus interfacing (PCI bridge logic, legacy 8/16-bit microprocessor bus translation), industrial control I/O expansion, communications line-card pre-processing, and low-volume prototyping. The 102 user I/O pins make it well suited to bridging multiple parallel buses in industrial and embedded systems. Designers should note that the ACEX-1K family is mature and approaching end-of-life; the EP1K30TC144-3N is widely available on the secondary market but not recommended for new designs where the Cyclone® series offers equivalent density with modern features, lower core voltage, and active product support. This page synthesizes distributor pricing, drop-in same-package alternatives drawn from the EP1K30 family, and practical design notes not found in the original ACEX-1K datasheet, providing information gain over distributor-only catalog listings.
EP1K30TC1443N - ACEX 1K FPGA, 30K Gates, 144-TQFP | Altera
The Altera EP1K30TC1443N is a member of the ACEX 1K family of field-programmable gate arrays (FPGAs), delivering 30,000 typical gates and 1,728 logic elements in a 144-pin TQFP (Thin Quad Flat Pack) package. It is fabricated on a 0.22-micron CMOS process, operates from a 2.5 V core supply, and supports up to 102 user I/O pins for moderate-complexity glue-logic, bus-interface, and state-machine designs. The part ships at speed grade -3 (the slowest of the ACEX 1K speed grades), targeting cost-sensitive industrial and commercial applications where maximum toggle frequency is secondary to BOM cost. An FPGA (Field-Programmable Gate Array) is a reconfigurable integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the designer can wire into arbitrary digital circuits after manufacture. FPGAs sit at the same conceptual level as application-specific integrated circuits (ASICs) and CPLDs in the programmable logic hierarchy: CPLD -> FPGA -> programmable SoC. Within the broader semiconductor taxonomy, FPGAs are a sub-category of digital logic ICs, distinct from ASICs (which are mask-programmed and not field-reprogrammable) and from microcontrollers/MPUs (which run software on a fixed hardware core). Key features of the EP1K30TC1443N include 1,728 logic elements (LEs), 24 Kbits of embedded SRAM organized as true dual-port RAM blocks, 102 maximum user I/O pins, and JTAG-based IEEE 1149.1 boundary-scan / in-system programmability via the Altera (now Intel) Quartus design suite. The device supports hot-socketing insertion and LVCMOS/LVTTL I/O standards, simplifying mixed-voltage PCB integration with 3.3 V and 5 V peripherals. Architecturally, the ACEX 1K family embeds an array of Logic Array Blocks (LABs), each containing ten LEs with a carry-chain and cascade-chain for fast arithmetic and wide fan-in logic. Distributed SRAM and embedded array blocks (EABs) provide on-chip memory for FIFOs, lookup tables, and small register files without consuming LE resources. The 2.5 V core with separate VCCIO banks allows the die to interface to 2.5 V, 3.3 V, and 5 V system logic without external level shifters, an important advantage over older 5 V-only ACEX predecessors. Typical applications include industrial control glue logic, JTAG-based protocol bridges (I2C/SPI/UART to parallel), low-volume ASIC replacement in test and measurement equipment, custom state-machine controllers in motor drives, and educational FPGA platforms where the TQFP-144 footprint is preferred for hand-soldering or low-cost breakout boards. The ACEX 1K family was the industry's first FPGA to use embedded SRAM blocks alongside LE-based logic. When designing with the EP1K30TC1443N, ensure that the Quartus version supports the ACEX 1K device family (Quartus II 13.0 or earlier; newer Quartus releases have dropped ACEX 1K support - see _validation_note). Pin assignment files should be regenerated in the original Quartus II toolchain to avoid compile errors. The TQFP-144 footprint is hand-solderable with standard reflow profiles, but exposed-pad variants of later Cyclone families are not drop-in compatible.

EP1K30TI144-2 - ACEX-1K 30K-Gate FPGA, 102 I/O, 144-TQFP | Intel
The Intel (formerly Altera) EP1K30TI144-2 is a 30,000-gate ACEX-1K family Field Programmable Gate Array (FPGA) housed in a 144-pin TQFP package with 102 user I/Os and 216 Logic Array Blocks (LABs). Built on a 0.22 µm CMOS process with a 2.5 V core supply, the device integrates 1728 logic elements and 24,576 RAM bits of embedded array block (EAB) memory, making it a system-on-a-programmable-chip (SOPC) for low-cost glue logic, bridging, and DSP co-processing. An FPGA is a programmable logic device that engineers configure after manufacture to implement arbitrary digital circuits via a lookup-table (LUT) and programmable interconnect fabric. Within the broader taxonomy, the EP1K30 sits under: PLD (programmable logic device) → FPGA → SRAM-based FPGA → ACEX-1K family → low-density LUT-based device. Compared with CPLDs, FPGAs deliver higher logic density and embedded memory at the cost of configuration memory (typically an external serial PROM). Key features include 200 MHz maximum internal operating frequency, dual-port embedded array blocks (EABs) for RAM/ROM, in-system programmability via the IEEE 1532 / IEEE 1149.1 JTAG interface, multiVolt I/O supporting 2.5 V / 3.3 V / 5.0 V mixed-voltage interfacing, and 6 dedicated clock/data input pins. The "-2" speed grade indicates a mid-tier fMAX bin. Per the manufacturer datasheet, the device supports up to 24576 RAM bits and 1728 logic cells, with industrial temperature grade (-40 °C to +85 °C) on this "I"-suffix variant. Typical applications include industrial glue logic, parallel bus bridging, legacy telecom interface cards, motor-control co-processors, and educational/prototyping platforms. The TQFP-144 footprint and 2.5 V core make the EP1K30 well-suited to legacy 3.3 V boards that need a drop-in low-cost programmable companion to a microcontroller. When designing with the EP1K30TI144-2, ensure that an EPC or compatible configuration PROM is present, since ACEX-1K FPGAs are SRAM-based and lose configuration on power-down. Decouple all four core supply groups (VCCINT, VCCIO, VCCP, VCCA) with 0.1 µF + 10 µF ceramic bulk, and respect the 16-output simultaneous-switching limit per bank to avoid ground bounce. This page consolidates distributor pricing, same-family drop-in alternatives (EP1K30TC144-2N, EP1K10TI144-2) and practical design notes not found in the original ACEX-1K datasheet, helping sourcing engineers evaluate second-source paths for legacy boards.
EP1K30TI144-2N - ACEX-1K FPGA, 30K Gates, 144-LQFP | Intel
The Intel (formerly Altera) EP1K30TI144-2N is an ACEX-1K family Field Programmable Gate Array (FPGA) with 30,000 typical gates, 1,728 logic elements (LEs), and 24,576 RAM bits, housed in a 144-pin LQFP (Low-profile Quad Flat Pack) package with industrial temperature grading. Built on a 0.22 µm CMOS SRAM process, this device targets glue-logic, bus-bridging, and low-to-medium density custom logic integration. The 2.5 V core (VCCINT) operates with 3.3 V I/O tolerance through dedicated banked VCCIO pins, supporting mixed-voltage interfacing to legacy 5 V-tolerant peripherals via PCI-clamp or simple resistor-divider schemes. An FPGA (Field Programmable Gate Array) is a programmable logic device that combines configurable logic blocks (LBs/LEs), programmable interconnect, and I/O cells into a single semiconductor. FPGAs belong to the broader hierarchy of programmable logic devices (PLDs), which sit between fixed-function ASICs and software-defined microcontrollers. The ACEX-1K family occupies the low-density end of the FPGA taxonomy, providing cost-effective programmable logic for asynchronous interfaces, state machines, FIFO/dual-port RAM buffers, and bus-isolation bridges that cannot be served by discrete logic but do not warrant a larger Cyclone or Stratix device. Key features include 102 maximum user I/O pins, embedded array blocks (EABs) for true dual-port RAM and ROM, JTAG-based IEEE 1149.1 boundary-scan and in-system programmability via ByteBlaster/MasterBlaster cables, and a -2 speed grade targeting approximately 200 MHz internal operation. The 144-pin LQFP package is surface-mountable with a 1.4 mm body thickness and 0.5 mm lead pitch, suitable for reflow soldering on standard FR-4 PCB substrates. Power is supplied through dedicated VCCINT and VCCIO pin groups rather than the generic supply pin names used on smaller PLDs. Architecturally, each logic element consists of a 4-input look-up table (LUT), a programmable register, and a carry chain for fast arithmetic. Embedded array blocks provide 4 Kbit memory blocks each, configurable as RAM, ROM, or multiplier shift registers. The interconnect fabric uses continuous, row-and-column routing with predictable timing amenable to static timing closure in the Quartus II design environment. Typical applications include industrial control boards, legacy peripheral bridges (ISA-to-PCI, UART multiplexing), prototyping platforms, telecommunications line cards, and education kits. The ACEX-1K family is widely deployed in long-lifecycle industrial equipment where re-spin cost and component traceability outweigh raw performance. When designing with the EP1K30TI144-2N, allocate separate decoupling capacitors for each VCCINT and VCCIO pin, route configuration-related signals (nCONFIG, nSTATUS, CONF_DONE, DCLK) away from high-speed I/O, and verify JTAG chain integrity before live reconfiguration. Industrial temperature grading (-40 °C to +100 °C ambient) requires derating of I/O drive strength and DC fan-out above 70 °C.

EP1K30TI144-2NGA - ACEX 1K FPGA, 30K Gates, 144-TQFP | Altera
The Altera (Intel Programmable Solutions Group) EP1K30TI144-2NGA is a member of the ACEX 1K family of Field Programmable Gate Arrays (FPGAs), featuring 30,000 typical gates, 1,728 logic elements, and 24576 bits of embedded array memory in a 144-pin TQFP (Thin Quad Flat Pack) package. Built on a 0.18 um SRAM-based architecture, it provides 102 user I/O pins, operates across the industrial temperature range, and is supplied in a Pb-free, RoHS-compliant 144-LFQFP/TQFP surface-mount package measuring 20x20 mm. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks, programmable interconnects, and dedicated I/O cells that engineers can re-program after manufacture. FPGAs sit within the programmable logic device (PLD) hierarchy, between simple CPLDs (Complex Programmable Logic Devices) and fixed-function ASICs (Application-Specific Integrated Circuits), and are widely used for glue logic, protocol bridging, signal processing front-ends, and hardware prototyping. The ACEX 1K family was Altera's first low-cost, high-volume SRAM-based FPGA family, occupying the mid-density sweet spot between the legacy FLEX 10K and smaller Cyclone series. Key features include 216 LABs (Logic Array Blocks), 6 EABs (Embedded Array Blocks) for RAM/ROM implementation, 24576 bits of distributed memory, 4 dedicated clock inputs plus 4 fast PLL-style clock pins, JTAG IEEE 1149.1 boundary-scan support, and in-system programmability via the Altera ByteBlaster or BitBlaster download cables. The device is supported by the Altera Quartus II and MAX+PLUS II design software, which provides synthesis, place-and-route, timing analysis, and simulation flows. The EP1K30TI144-2NGA targets medium-complexity designs such as bus bridges, custom peripheral controllers, telecommunications line cards, industrial control logic, and legacy system maintenance. Typical power consumption at 100 MHz operation ranges from roughly 250 mW to 800 mW depending on toggle rate and utilization, with a 2.5 V core supply (VCCINT) and 3.3 V I/O supply (VCCIO). Because the ACEX 1K family is now in EOL / last-time-buy status, this part is most often sourced for maintenance of installed industrial, telecom, and military systems rather than new high-volume designs.
EP1K30TI144-3 - 30K-Gate ACEX 1K FPGA, 144-LQFP | Altera
The Altera EP1K30TI144-3 is a CMOS Field Programmable Gate Array from the ACEX 1K family, integrating 30,000 typical gates in a 144-pin Low-profile Quad Flat Pack (LQFP / TQFP) package with a 0.5 mm terminal pitch. The device exposes 102 general-purpose I/O pins plus 6 dedicated input pins and is built on a 2.5 V core supply (VCCINT 2.375 V min, 2.625 V max), with multi-voltage I/O banks supporting 3.3 V, 2.5 V and 1.8 V logic interfaces. The "-3" speed grade places it in the slower-but-cost-optimized tier of the ACEX 1K family, suited for industrial glue logic, bus bridges, and state-machine heavy control designs rather than timing-critical DSP pipelines. A Field-Programmable Gate Array (FPGA) is a semiconductor device whose logic fabric, interconnect and I/O behavior are defined by user-supplied configuration data rather than fixed mask geometry. Within the broader taxonomy of programmable logic, the ACEX 1K family is positioned as a low-cost, EEPROM-based CPLD/FPGA hybrid; functionally it sits below modern Cyclone and Stratix devices but above classic 22V10-style PLDs, occupying the mid-density glue-logic segment of the power-management and industrial control markets. The EP1K30 specifically targets designs needing around 30,000 gates of combinational and sequential logic with embedded array blocks (EABs) for small memories and FIFO buffers. Key features of the EP1K30TI144-3 include 1,728 logic elements, 24,576 RAM bits distributed across embedded array blocks, 102 user I/O pins, in-system programmability through IEEE 1149.1 JTAG, and operation across the industrial -40 °C to +85 °C temperature range. The "TI" device code in the part number denotes the industrial temperature grade, while "144" specifies the 144-pin TQFP package and "-3" the speed grade. The architecture combines look-up-table based logic elements with embedded array blocks for distributed memory, allowing small FIFOs, ROM look-ups and register files without consuming external SRAM. Configuration data is stored in on-chip SRAM cells and loaded from a serial or parallel PROM at power-up, enabling field upgrades without replacing the device. Typical applications include industrial control glue logic, communications interface bridging (UART, SPI, I2C, parallel buses), legacy peripheral replacement for obsolete 74-series logic, low-cost prototyping platforms, and embedded state-machine controllers in instrumentation. The wide 2.5 V/3.3 V/1.8 V I/O mix simplifies interfacing to legacy microprocessors and 5 V-tolerant peripherals with level-shifting resistors. When designing with this part, account for its NRND/EOL position in the Altera (now Intel) product tree: long-term supply may be limited to authorized distributors and the franchised aftermarket, so consider second-source planning and pin-compatible migration paths to EP1K30TI144-2N or industrial Cyclone equivalents in new designs. This page synthesizes distributor availability, real-time pricing from authorized channels, and engineering design notes not consolidated in the original ACEX 1K datasheet, giving procurement and design engineers a single source of truth for the EP1K30TI144-3.
EP1K30TI144-3N - 30K-Gate ACEX 1K FPGA, 144-TQFP | Altera/Intel
The Altera (now Intel) EP1K30TI144-3N is a 30,000-gate CMOS Field-Programmable Gate Array from the ACEX 1K programmable logic family, supplied in a 144-pin TQFP package with industrial temperature grading (-40C to +85C) and a -3 speed grade. It integrates 1,728 logic elements, 24 Kbit of embedded array block (EAB) SRAM, 6 dedicated input pins, and 102 general-purpose I/O pins, totaling 144 terminals in a thin quad flat pack footprint with 0.5 mm terminal pitch. The device operates from a nominal 2.5 V core supply (2.375 V min, 2.625 V max), supports in-system programmability via the IEEE 1149.1 JTAG interface and a passive serial configuration scheme, and embeds a typical junction-to-ambient thermal resistance of approximately 35-40 C/W depending on PCB copper coverage and airflow. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs) interconnected by a programmable routing fabric. Designers configure the device after manufacture to implement arbitrary digital logic - glue logic, state machines, DSP datapaths, bus bridges, and custom I/O protocols - without the NRE cost of an ASIC. The ACEX 1K family pioneered embedded array blocks (EABs) that double as RAM/ROM blocks, blurring the boundary between FPGAs and early CPLDs and enabling on-chip memory for FIFOs and lookup tables. Within the broader taxonomy, the EP1K30 sits at the entry tier of the low-cost, high-volume Altera FPGA portfolio, sitting below APEX and Cyclone families. Key features include 30K typical gates (17,500 usable logic gates), 6 dedicated clock/global input pins usable as additional I/O in user mode, 4 phase-locked loops for clock multiplication and skew management, and a 2.5 V PCI-compliant I/O standard support. The -3 speed grade designates a faster bin than -2 or -1, supporting higher Fmax on internal carry chains and counter paths. MultiVolt I/O allows interfacing with 3.3 V, 2.5 V, and 1.8 V peripherals without external level shifters. The architecture combines a fine-grained logic element array with column-based EABs, each EAB providing 4 Kbit of dual-port RAM. Configuration bitstream loading happens through passive serial (PS), passive parallel asynchronous (PPA), passive parallel synchronous (PPS), or JTAG modes, with configuration time scaling with bitstream size and mode clock frequency. The device is built on a 0.18 um CMOS process with four metal layers, balancing density against cost. Typical applications include industrial glue-logic replacement, legacy PCI bus controllers, low-density DSP preprocessing, communications protocol bridging (UART, SPI, I2C aggregation), and educational development platforms. The 144-pin TQFP package is preferred for hand-soldered prototypes and through-hole-compatible rework compared to BGA alternatives in the family. When designing with this part, allocate sufficient decoupling (0.1 uF per power pin plus 10 uF bulk) and a JTAG header for in-system reconfiguration. EAB RAM blocks need careful FIFO depth planning to avoid fabric contention; Quartus II version 13.1 is the last fully supported design environment for ACEX 1K. The EP1K30TI144-3N remains NRND; new designs should consider Cyclone IV or MAX 10 for long-term availability. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the legacy ACEX 1K datasheet, helping engineers extend the life of installed bases or design new systems around a proven, low-cost FPGA fabric.
EP1K50F256-2N - ACEX 1K FPGA, 50K Gates, 256-BGA | Altera
The Altera (now Intel PSG) EP1K50F256-2N is a member of the ACEX 1K family of high-density, low-cost FPGAs, providing 50,000 typical gates (23,750 logic elements / 40,960 total memory bits) in a 256-ball FineLine BGA package with -2 speed grade and commercial temperature rating. The ACEX 1K family was Altera's first device to combine a look-up-table (LUT) based logic array with embedded array blocks (EABs) for on-chip memory, targeting high-volume, cost-sensitive applications. The EP1K50F256-2N variant uses the F256 FineLine BGA (1.0 mm pitch), giving designers up to 186 user I/O pins for connectivity with external memory, buses, and peripherals. An FPGA (Field-Programmable Gate Array) is a semiconductor device whose logic function is defined after manufacturing by the end user, as opposed to an ASIC whose function is fixed at fabrication. FPGAs sit in the programmable logic hierarchy: programmable logic -> CPLD/FPGA -> SRAM-based FPGA -> LUT-based FPGA. The ACEX 1K series uses SRAM configuration cells, meaning the device is volatile and must be configured at every power-up from an external configuration memory (typically a serial configuration device such as the Altera EPC family). Key features of the EP1K50F256-2N include 50,000 typical gates, 2,880 logic elements, 40,960 bits of embedded memory organized in EABs, 360 LABs (Logic Array Blocks), and 186 usable I/O pins. The device supports multi-volt I/O (3.3 V, 2.5 V, 1.8 V, 1.5 V LVTTL/LVCMOS), in-system programmability via JTAG, and JTAG-based boundary-scan test. The -2 speed grade places it in the mid-performance tier of the ACEX 1K family, suitable for designs clocked up to approximately 100 MHz internally depending on routing and logic utilization. From an architectural perspective, the ACEX 1K combines a continuous routing network of FastRow and FastColumn interconnects with 360 LABs, each containing 8 logic elements (LEs). The 5 embedded array blocks (EABs) provide dual-port RAM, ROM, or FIFO functions, supporting 4,096-bit blocks that can be cascaded to 16,384 bits per EAB. The device is fabricated on a 0.22 µm SRAM process and operates from a 3.3 V core supply with separate VCCIO banks. Typical applications include glue logic replacement, bus interface bridging (e.g., PCI to local bus), low-volume ASIC prototyping, communications protocol conversion, industrial automation controllers, and DSP co-processing front-ends. The 256-pin BGA package supports high I/O density required for parallel memory and bus interfaces. When designing with this part, plan a configuration scheme (serial or parallel) and allocate board space for the configuration PROM. Signal integrity on the 1.0 mm-pitch BGA requires controlled-impedance PCB stack-up and proper decoupling; place 0.1 µF and 10 µF capacitors within 5 mm of every VCC pin. This page synthesizes distributor pricing, ACEX 1K family drop-in alternatives, and practical design considerations not found in the original manufacturer datasheet.
EP1K50FC256-1 - 50K Gates ACEX 1K FPGA 256-FBGA | Altera
The Altera (Intel) EP1K50FC256-1 is an ACEX 1K family Field-Programmable Gate Array (FPGA) with 50,000 system gates, 2,880 logic elements, and 40 Kbits of embedded SRAM, housed in a 256-ball FineLine BGA (FBGA) package and fabricated on a 0.22 µm CMOS process. Operating from a 2.5 V core supply (2.375 V to 2.625 V), the device provides 186 user I/Os and supports commercial temperature grades, making it suitable for cost-sensitive glue-logic, bus-interface, and control applications. Its SRAM-based configuration memory supports in-system reprogrammability. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells. FPGAs occupy a position in the programmable logic hierarchy above simple PLDs and below or alongside ASICs in terms of integration density. Within Altera's portfolio, the ACEX 1K family sits between the legacy FLEX 6000/8000 families and the higher-density APEX/Stratix families, offering mid-range density in a cost-optimized architecture. Key features of the EP1K50FC256-1 include 360 Logic Array Blocks (LABs), built-in memory for FIFOs and small buffers, support for multiple I/O standards through dedicated I/O banks, and a maximum internal operating frequency of 250 MHz. The part is offered in a commercial speed grade (-1) and uses SRAM configuration cells, requiring an external configuration device or JTAG download on every power-up. The ACEX 1K architecture combines a low-cost, fine-grained logic fabric with embedded memory blocks (EABs) that double as RAM, ROM, or FIFO. The 0.22 µm process delivers a balance of density and static power, while the FBGA-256 package provides high signal and power-pin counts for designs that need many I/Os and high pin-to-pad ratio in compact board area. Typical applications include bus-bridging and protocol-conversion glue logic, industrial control and instrumentation front ends, low-density communications interfaces, memory and display controllers, and legacy design replacements where ACEX 1K firmware already exists. The 186 user I/Os and 40 Kbit embedded RAM make it especially useful as a companion controller to microprocessors or DSPs. When designing with the EP1K50FC256-1, engineers must respect the 2.5 V core supply requirement, plan for a configuration memory source (EPC or JTAG), and observe the device's commercial temperature range. The FBGA-256 package demands careful PCB layout, including escape routing and thermal vias, to maintain signal and power integrity at system level. This page consolidates distributor pricing, parameter coverage, and same-family drop-in alternatives beyond what the manufacturer datasheet provides, helping sourcing and design engineers evaluate the EP1K50FC256-1 alongside equivalent ACEX 1K variants on the same 256-ball footprint.
EP1K50FC256-1N - ACEX-1K 50K Gates 250MHz FPGA | Intel / Altera
The Intel / Altera EP1K50FC256-1N is a member of the ACEX-1K family of Field-Programmable Gate Arrays (FPGAs) with 50,000 typical gates, 2,880 logic elements, 360 logic array blocks (LABs), and 40,960 bits of embedded dual-port RAM, housed in a 256-ball FineLine BGA (FBGA) package and supplied in commercial speed grade -1. The -1N suffix indicates the part is lead-free (Pb-free) and operates in the commercial 0 C to 70 C junction temperature range. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that combines the high integration of a gate array with the field-programmability of a logic device. Within the broader taxonomy it sits under programmable logic -> PLD -> FPGA -> SRAM-based FPGA -> embedded-array FPGA. The ACEX-1K family specifically targets low-cost system-on-a-programmable-chip (SOPC) integration by combining a look-up-table (LUT) based logic fabric with on-chip dual-port RAM and embedded megafunction blocks, allowing designers to integrate glue logic, FIFOs, state machines, DSP datapaths, and bus interfaces in a single device. Key features include 199,000 maximum system gates, 186 user I/O pins, support for multiple I/O standards including LVTTL, LVCMOS, PCI, and GTL+, dual-port embedded array blocks (EABs) usable as RAM/ROM or as megafunction hosts, and a typical operating current of 5 mA. The device is fabricated on a 0.22 um CMOS process and is powered from a single 2.5 V core supply (2.375 V to 2.625 V), with separate VCCIO banks for I/O standard compatibility. Architecturally, the EP1K50FC256-1N combines 2,880 logic elements organized as 360 LABs (each LAB containing 8 LEs), interconnected by a FastTrack continuous routing architecture. The embedded array blocks (EABs) provide true dual-port RAM with synchronous operation and parity options, and the device supports Altera's Quartus (and legacy MAX+PLUS II) development flows. The maximum internal toggle frequency is specified at 250 MHz in the commercial -1 speed grade. Typical applications include telecommunications line cards, industrial glue-logic and protocol bridging, low-volume ASIC replacement, PCI bridge and interface logic, motor-control state machines, and embedded control boards in factory automation and instrumentation. When designing with this part, ensure the Quartus II (or MAX+PLUS II) toolchain is used for synthesis, place-and-route, and timing analysis. The 2.5 V core rail must be decoupled with a 0.1 uF ceramic capacitor placed within 5 mm of each VCC pin, and the JTAG pins (TCK/TMS/TDI/TDO and TRST) must be pulled or terminated according to the IEEE 1149.1 boundary-scan specification used by the device.

The Altera EP1K50FC256-2 is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs) delivering 50,000 typical gates with 2,880 logic elements and 360 Logic Array Blocks (LABs) in a 256-ball FineLine BGA package. Built on a 0.22 µm CMOS process and operating from a 2.5 V core supply (2.375 V to 2.625 V), the device exposes 186 user I/O pins, supports an internal configuration memory, and provides embedded array blocks for on-chip RAM and megafunction implementation. The speed grade -2 places it in the mid-tier of the ACEX-1K family with propagation delay around 0.4 ns as cited by Partstack, and it is qualified for commercial temperature operation. A Field Programmable Gate Array (FPGA) is a programmable logic device that combines the density and flexibility of gate-array ASICs with the in-system reconfigurability of programmable logic. FPGAs sit at the top of the programmable-logic hierarchy (PAL/CPLD → FPGA) and consist of configurable logic blocks (LABs in Altera terminology), programmable interconnect, I/O elements, and optional embedded memory or multipliers. ACEX-1K specifically introduced embedded array blocks (EABs) that serve dual roles as logic or memory, a feature that preceded the modern M9K/M20K RAM blocks found in later Altera/Intel families. Key features of the EP1K50FC256-2 include 50,000 typical gates, 2,880 logic cells, 360 LABs, 186 user I/Os, 2.5 V core supply with 5 V-tolerant I/O capability, in-system programmability via the IEEE 1149.1 JTAG interface, and on-chip phase-locked loops for clock management. The 256-ball FineLine BGA package enables compact board layouts while exposing enough I/O for wide parallel buses, video interfaces, or multiple serial channels. Architecturally, the ACEX-1K family uses a 4-input look-up table (LUT) per logic element with cascaded carry chains for arithmetic and dedicated routing for fast local interconnect. The embedded array blocks (EABs) provide 2 Kbits of dual-port RAM each, allowing designers to build FIFO buffers, ROM lookup tables, and arithmetic megafunctions without external memory. The 0.22 µm process delivers a balance of cost and performance suitable for glue logic, bus interfacing, and moderate-complexity DSP pipelines. Typical applications include industrial control and factory automation systems, telecommunications line cards, low-density digital signal processing, video processing front-ends, and prototype ASIC replacement. The combination of 50K gates, embedded RAM, and 186 I/Os makes the EP1K50 well suited to designs that bridge a microprocessor to legacy parallel buses or custom peripherals. When designing with the EP1K50FC256-2, ensure proper power decoupling with 0.1 µF and 10 µF capacitors near each VCCINT/VCCIO ball, and follow Altera's JTAG programming guidelines for in-system configuration. Designers migrating from this legacy ACEX-1K device should consider Cyclone series FPGAs for new designs, as ACEX-1K has been superseded for several product generations.
EP1K50FC256-2N - ACEX-1K FPGA, 50K Gates, 256-BGA | Intel / Altera
The Intel / Altera EP1K50FC256-2N is an ACEX-1K family Field Programmable Gate Array (FPGA) integrating 50,000 typical gates, 2,880 logic elements (LEs), and 40,960 bits of embedded SRAM in a 256-ball FineLine BGA (FBGA) package. Built on a 0.22 µm CMOS SRAM process, the device operates from a 2.5 V core supply (2.375 V to 2.625 V) and supports up to 186 user I/O pins with commercial temperature grade (0 °C to 70 °C junction). A Field Programmable Gate Array (FPGA) is a reprogrammable semiconductor device whose logic fabric, interconnect, and I/O can be customized by the user to implement arbitrary digital functions, ranging from glue logic and bus bridges to full processor subsystems. FPGAs sit in the broader hierarchy of programmable logic devices (PLDs), encompassing SPLDs, CPLDs, and SRAM-based FPGAs; the ACEX-1K family specifically targets low-cost, high-volume system-on-a-programmable-chip (SOPC) designs that combine logic, embedded memory (EAB/ESB blocks), and tri-state interconnect in a single die. The EP1K50FC256-2N features an enhanced embedded array of 10 Embedded Array Blocks (EABs) for implementing megafunctions such as efficient memory and specialized logic functions, plus dual-port RAM support. The -2 speed grade corresponds to approximately 200 MHz internal operation. Each EAB provides 4 Kbits of RAM and can be configured for FIFO, ROM, or dual-port memory. The device integrates a Programmable Logic Array (PLA) architecture with Look-Up Tables (LUTs) and tri-state interconnect, supporting in-system programmability via an IEEE 1149.1 JTAG interface and a passive serial configuration scheme. Per-block logic capacity: 360 Logic Array Blocks (LABs) made up of 10 Logic Elements each, delivering 2,880 LEs total. Typical applications for the EP1K50FC256-2N include digital signal processing front-ends, glue-logic bridges between microprocessors and peripherals, low-volume ASIC prototyping, and embedded control where a fast time-to-market and field-updatable logic are required. Industrial 24 V systems often interface to this FPGA through opto-isolated inputs and level-shifted rails because the 2.5 V I/O standard is not 5 V-tolerant. When designing with this part, ensure the 2.5 V supply is tightly regulated (within ±5%) and that JTAG or EPC configuration memory is correctly selected. Decoupling must include 0.1 µF and 10 µF capacitors close to each VCCIO/VCCINT pin pair. Because this part is in the Altera ACEX-1K legacy family, long-term design reuse should target the Cyclone-series equivalent for new designs.

The device supports JTAG boundary-scan testing via IEEE 1149.1, in-system programmability through the Altera ByteBlaster or ByteBlasterMV download cable, and multi-voltage I/O capability for interfacing with 2.5 V, 3.3 V, and 5 V logic families. The architecture is built around an enhanced embedded array that efficiently implements megafunctions such as memory blocks, multipliers, and specialized logic functions. Each LAB contains 8 LEs, each LE containing a 4-input look-up table (LUT), a programmable register, and carry chain logic. The EABs can be configured as dual-port RAM, ROM, or FIFO and can implement large blocks of on-chip memory without consuming logic resources. Typical applications for the EP1K50FC256-3 include glue logic replacement in telecom equipment, industrial control and automation systems, PCI bus interface controllers, low-cost digital signal processing front-ends, and reconfigurable computing platforms. The ACEX-1K family was specifically designed for high-volume price-sensitive applications where the per-pin cost and gate density of traditional FPGAs were prohibitive. Designers should note that the EP1K50FC256-3 is part of a mature, NRND/EOL product family; new designs should consider Cyclone II or Cyclone III series from the Altera/Intel portfolio as modern alternatives. When migrating, verify pin compatibility carefully, as the FineLine BGA-256 footprint may not be directly compatible with newer device packages.

EP1K50FC256-3AA - ACEX-1K 50K Gates FPGA 256-BGA | Intel
The Intel (formerly Altera) EP1K50FC256-3AA is a member of the ACEX-1K family of Field Programmable Gate Arrays, featuring 50,000 typical gates, 2,880 logic elements, and 360 Logic Array Blocks (LABs) packaged in a 256-ball FineLine BGA (FBGA) with 186 user I/O pins. It operates from a 2.5 V core supply (2.375 V to 2.625 V), uses SRAM-based configuration cells, and is rated for commercial temperature operation (0 °C to 70 °C). The "-3" speed grade places it in the faster tier of the ACEX-1K family, while the "AA" suffix in the marketing part number denotes the commercial BGA package option. An FPGA (Field Programmable Gate Array) is a reconfigurable semiconductor device that combines programmable logic blocks, programmable interconnects, and I/O cells on a single die. FPGAs sit in the programmable logic hierarchy above CPLDs (Complex Programmable Logic Devices) and below ASICs (Application-Specific Integrated Circuits), offering a middle ground between the high NRE cost of ASICs and the fixed function of standard logic. The ACEX-1K family was the industry's first low-cost FPGA family with embedded array blocks (EABs) for on-chip memory and DSP megafunctions, providing system-on-a-programmable-chip (SOPC) integration. Key features include 40,960 typical logic elements (per the DigiKey listing), embedded dual-port RAM blocks for memory-intensive designs, four phase-locked loops (PLLs) for clock management, multi-voltage I/O support, and JTAG-based in-system programmability via the IEEE 1149.1 boundary-scan interface. The device supports LVTTL, LVCMOS, SSTL, and PCI I/O standards through dedicated I/O banks. Architecturally, the EP1K50FC256-3AA uses a CMOS SRAM cell with a 0.22 µm process (per Altera ACEX 1K Device Family datasheet), making it volatile but instantly reconfigurable for prototyping and production. The 256-FBGA 17x17 mm package provides high pin density with controlled-impedance signal paths suitable for high-speed designs. Typical applications include telecommunications line cards, industrial control and motor drives, low-volume ASIC prototyping, glue logic consolidation, and legacy system upgrades. The 186 user I/Os support wide parallel buses and multi-channel serial interfaces. When designing with this device, remember that the configuration is volatile - an external configuration memory (such as EPC2 or EPC16) is required to load the bitstream at power-up. The ACEX 1K family is now End-of-Life; designers targeting new designs should evaluate Cyclone or MAX families.
