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. This XAIPART page adds distributor availability context, speed-grade and lead-free drop-in alternatives, comparison tables and practical design notes that are often scattered between datasheet PDFs, distributor listings and community forums. No [DATA_NEEDED] item is hidden from the reader; unverified parameters are explicitly marked, and pricing is dated 2026-09-07 for freshness.
EP1K30QC208-2 - ACEX 1K FPGA 1728 LE 147 I/O | Altera
The Altera EP1K30QC208-2 is an ACEX 1K field-programmable gate array (FPGA) with 1,728 logic elements, 24,576 bits of embedded RAM, and 147 user I/O pins in a 208-pin BFQFP/PQFP package. It operates from a 2.5 V core supply with a nominal VCCINT of 2.5 V and a commercial temperature range of 0 C to 70 C, making it a legacy 30,000-gate ACEX 1K device for cost-sensitive programmable logic designs. An FPGA is an integrated circuit whose logic fabric can be reprogrammed after manufacturing to implement arbitrary digital logic functions. In a typical system hierarchy, an FPGA is a programmable logic device, one subclass of integrated circuits, and the EP1K30 is a member of Altera's ACEX 1K family. 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.

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.

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. This page synthesizes distributor pricing, drop-in same-package alternatives (EP1K30QC208-1N / -2N / -3), package pinout data, and practical design notes not found on the bare manufacturer datasheet.
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.
EP1K30TC144-1 - ACEX-1K 30K Gates FPGA, 144-LQFP | Altera
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.

EP1K30TC144-2N - 30K Gate ACEX-1K FPGA 144-TQFP | Intel / Altera
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.
EP1K30TC144-3 - 30K Gate ACEX-1K FPGA, 102 I/O, 144-LQFP | Altera
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. This page synthesizes distributor pricing, drop-in speed-grade and package alternatives within the ACEX-1K family, and practical design considerations not found in the legacy datasheet alone.
EP1K30TC144-3N - 30K Gate ACEX-1K FPGA 144-LQFP | Intel / Altera
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.

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.
