EP1K30FC256-1 - 30K Gate ACEX-1K FPGA 256-BGA | Intel

The Intel (formerly Altera) EP1K30FC256-1 is a member of the ACEX-1K FPGA family, delivering 30,000 typical gates (17,280 logic elements / 1,728 logic cells) with 24,576 RAM bits in a 256-ball FineLine BGA package. It provides 171 user I/O pins and operates from a 2.5V core supply, with a -1 speed grade optimized for cost-sensitive commercial designs. What is an FPGA? A Field-Programmable Gate Array (FPGA) is a reconfigurable integrated circuit containing an array of programmable logic blocks, configurable interconnect, and embedded memory blocks that the designer programs after manufacture. The ACEX-1K family sits in the low-density, low-cost tier of the broader programmable logic hierarchy: CPLD (smaller, non-volatile) -> ACEX-1K / Cyclone (low-density SRAM FPGA) -> Cyclone II/III/IV/V (mid-density) -> Stratix (high-density) -> FPGA & CPLD category. SRAM-based FPGAs require a configuration flash at every power-up but deliver far higher logic capacity per dollar than CPLDs of the same era. Key features include embedded array blocks (EABs) for efficient memory and specialized logic function implementation, dual-port RAM support, 250 MHz internal performance, JTAG-based boundary-scan testing, and SameFrame pin-out compatibility that allows migration between density points and speed grades within the same 256-BGA footprint. The device is fabricated on a 2.5V CMOS process and supports in-system programmability via the Altera ByteBlaster or parallel configuration interfaces. The EP1K30FC256-1 architecture combines a fine-grained logic element array with coarse-grained embedded array blocks (EABs), enabling efficient implementation of both random logic and wide memory functions such as FIFOs, ROMs, and DSP-style multiplier-accumulator blocks. The 24,576 bits of distributed RAM and the 250 MHz system clock make the device suitable for glue-logic replacement, bus-interface bridging, and small-scale state-machine control in industrial and telecommunications equipment. Typical applications include glue logic replacement, bus-interface bridges (e.g., PCI to local bus), telecom line-card glue logic, industrial control and instrumentation front-ends, low-density DSP co-processing, and legacy system refresh designs that benefit from SameFrame footprint migration across the ACEX-1K family. The 171 user I/Os also make it suitable for display driving and parallel data acquisition front-ends. When designing with the EP1K30FC256-1, ensure the configuration device is selected to match the chosen configuration scheme (passive serial, passive parallel, or JTAG). Decoupling capacitors should be placed as close as possible to every VCCINT and VCCIO pin per Altera application note guidelines, and unused I/Os should be left floating or driven to a defined logic level. This page synthesizes verified distributor pricing, drop-in alternatives from the same ACEX-1K family, and practical design considerations that go beyond the manufacturer datasheet summary.

EP1K30FC256-1N

EP1K30FC256-1N - 30K Gate ACEX-1K FPGA 256-BGA | Intel

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

EP1K30FC256-2

EP1K30FC256-2 - 30K-Gate ACEX-1K FPGA, 256-BGA, -2 Speed | Intel

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

EP1K30FC256-2N - ACEX 1K FPGA, 1728 LEs, 171 I/O | Altera

The Altera EP1K30FC256-2N is an ACEX 1K family SRAM-based field-programmable gate array (FPGA) with 30,000 typical gates, 1728 logic elements, and 171 user I/O pins, supplied at 2.5 V and housed in a 256-ball FineLine BGA (FBGA) package. It is a low-cost programmable logic device built for system-on-a-programmable-chip (SOPC) integration, and this specific variant carries the -2 speed grade and the lead-free -N finish. A field-programmable gate array (FPGA) is an integrated circuit whose digital logic can be configured after manufacturing rather than being fixed at the factory. The FPGA sits inside the programmable logic device family, above it are programmable logic devices (PLDs), then integrated circuits, then semiconductors. In a typical system, an FPGA provides flexible glue logic, custom state machines, protocol bridging, and parallel compute structures that standard microcontrollers cannot easily implement, while retaining the ability to be reprogrammed during prototyping or production. Key features of the EP1K30FC256-2N include 216 logic array blocks, 24,576 RAM bits for on-chip FIFOs and buffers, and 171 user I/O pins. According to distributor and family datasheet summaries, the device can operate at internal clock frequencies up to 200 MHz and uses a 0.22 um process. The 2.5 V core supply permits low-power operation compared with earlier 5 V PLDs, while the 256-ball FBGA package provides a compact footprint for densely populated boards. From a technical standpoint, the ACEX 1K architecture combines logic elements with embedded array blocks that can implement memory and specialized functions. This makes the device suitable for datapath applications that require both distributed control logic and local data storage. The SRAM-based configuration is in-system programmable and typically loads from an external configuration device such as an EPC-series PROM at power-up. Typical applications include networking and communications equipment, industrial control panels, test and measurement systems, consumer audio/video bridging, and IoT sensor aggregation. The device is chosen when an engineer needs a moderate amount of programmable logic, many general-purpose I/O pins, and predictable low-cost performance on a 2.5 V design. A key design consideration is that the FPGA configuration is volatile: the bitstream must be loaded from external memory or a download cable after every power-up. Designers must also add adequate power-supply decoupling and carefully manage the FPGA configuration pins such as DCLK and CONF_DONE during board bring-up. This page synthesizes distributor pricing, ACEX 1K drop-in alternatives, practical design notes, and procurement guidance that are not normally listed together on a single manufacturer datasheet page. It is intended for engineers evaluating the EP1K30FC256-2N for legacy maintenance, replacement, or cost-sensitive programmable logic designs.

EP1K30FC256-3N - ACEX 1K FPGA, 30K Gates, 256-BGA | Intel

The Intel (formerly Altera) EP1K30FC256-3N is a member of the ACEX 1K family of low-cost SRAM-based FPGAs fabricated on a 0.22 µm CMOS process, integrating 30,000 typical gates (17,288 logic elements / 1,728 cells) into a 256-ball FineLine BGA (FBGA-256) package with 171 user I/Os. It operates from a 2.5 V core supply (2.375 V–2.625 V) and supports up to 24,576 RAM bits of embedded array memory distributed across 216 Logic Array Blocks (LABs), with system performance up to 200 MHz. An FPGA (Field-Programmable Gate Array) is a semiconductor device built from an array of configurable logic blocks (CLBs/LABs), programmable interconnect, and I/O cells that engineers can re-program in-system to implement arbitrary digital logic. ACEX 1K belongs to the broader programmable logic family hierarchy: FPGA → programmable logic device (PLD) → logic IC → integrated circuit. ACEX 1K positioned itself as a 'system-on-a-programmable-chip' (SOPC) platform, combining logic, embedded memory, and dual-port RAM in a single device for glue-logic and low-volume ASIC replacement. Key features of the EP1K30FC256-3N include the enhanced embedded array for implementing megafunctions such as efficient memory and specialized logic functions, dual-port RAM support, dedicated carry and cascade chains for high-performance arithmetic, JTAG-compliant boundary-scan testing per IEEE Std 1149.1, and 4-input look-up tables (LUTs) per logic element. The '3' speed grade offers typical propagation delays around 0.6 ns in the fastest paths. Architecturally, the EP1K30FC256-3N combines a 'FastTrack' continuous interconnect fabric with a distributed embedded array that can be configured as ROM, RAM, dual-port RAM, or first-in-first-out (FIFO) buffers. The device is configured via a serial or parallel configuration scheme using an Altera configuration EPROM or controller, supporting in-system programmability (ISP) through JTAG. Typical applications include digital signal processing glue logic, telecommunications interface bridging, peripheral bus expansion in PCI and embedded CPU systems, and industrial control logic where low unit cost, deterministic timing, and on-board reprogrammability outweigh the need for high logic density. The 171 user I/Os accommodate parallel buses, memory interfaces, and high-pin-count glue logic. When designing with the EP1K30FC256-3N, pay attention to multi-voltage I/O bank planning — the ACEX 1K family supports mixed-voltage interfacing on designated banks via VCCIO pins. Adequate decoupling (0.1 µF + bulk) and a solid ground pour are essential because the 256-ball BGA package relies on inner-plane thermal dissipation rather than a top-side heat spreader.

EP1K30FC256-3NAA

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.

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.

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.

It is built on a 0.22 µm CMOS process with a 2.5 V core supply and operates at up to 200 MHz system performance, providing system-on-a-programmable-chip (SOPC) integration in a single device. An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) that combines the density of an ASIC with the flexibility of in-system reprogrammability. The ACEX 1K family specifically targets cost-sensitive glue-logic, bus-interface, and DSP-coprocessor applications. It sits within the broader hierarchy of programmable logic: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit (IC) -> semiconductor. Compared with CPLDs, FPGAs offer much higher logic density and embedded memory, at the cost of volatile configuration and slightly higher power. Key features of the EP1K30QC208-2N include 147 user I/O pins, 216 logic array blocks (LABs), embedded dual-port RAM, a dedicated Double Data Rate (DDR) interface option, and an enhanced embedded array for implementing megafunctions such as efficient memory and specialized logic functions. The 208-pin PQFP package supports easy board-level assembly for prototype and low-to-mid volume production, while the 2.5 V core and multi-voltage I/O bank support simplify interfacing with 3.3 V and 5 V peripherals. Architecturally, the EP1K30QC208-2N uses a Lookup-Table (LUT)-based logic element with 4-input combinational capability and a register, organized into LABs with carry-chain and cascade-chain interconnect. The 24 Kbit embedded system block (ESB) memory can be configured as dual-port RAM, ROM, FIFO or CAM, removing the need for external SRAM in many data-pipeline designs. Configuration is loaded from a serial PROM via the dedicated configuration interface. Typical applications include glue logic between microprocessors and peripherals, custom bus bridges (PCI to local bus), DSP coprocessors, industrial control and instrumentation front-ends, telecommunications line cards, and legacy system refresh projects where a programmable replacement is preferred to an ASIC redesign. Designers often pair it with EPC2 configuration PROMs from Intel/Altera for standalone boot. When designing with this device, ensure the 2.5 V VCCINT and VCCIO bank supplies are properly decoupled (one 0.1 µF and one 10 µF per pin group) and that the configuration clock and MSEL pins are set for the desired configuration mode (AS, PS or JTAG). Because ACEX 1K parts have been EOL for many years, engineers should verify long-term availability before committing the part to new designs. This page consolidates manufacturer specification data, real-time distributor pricing, drop-in alternative cross-references and practical design notes that go beyond the original Altera ACEX 1K datasheet, helping procurement, design and component-engineering teams evaluate the EP1K30QC208-2N and its modern replacements in a single view.

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.

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.

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 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.

The Altera (now Intel) EP1K30TC144-1N is a member of the ACEX-1K family of SRAM-based, low-cost Field-Programmable Gate Arrays (FPGAs) offering 30,000 typical gates and 1,728 Logic Elements (LEs) in a 144-pin LQFP (TQFP) surface-mount package with 102 user I/O pins. The device is built on a 0.18 µm SRAM process and operates from a 2.5 V core supply with 3.3 V or mixed-voltage I/O, supporting industrial temperature ranges and reconfigurable in-system via the IEEE 1149.1 JTAG interface. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement arbitrary digital logic. Within the broader taxonomy, FPGAs belong to the programmable logic family, sitting alongside CPLDs and PALs. ACEX-1K is positioned by Altera as a low-cost, low-power programmable logic device family targeting glue logic, bus bridging, and moderate-density state-machine applications where a full Cyclone or Stratix device would be over-spec. Key features include 24,576 bits of embedded RAM organized in EAB (Embedded Array Block) memory, 6 EABs, dual-port RAM support, 6 phase-locked loops (PLUs) for clock management, and built-in support for LVCMOS, LVTTL, SSTL-2, and SSTL-3 I/O standards. The device is rated for -40 °C to +85 °C (commercial/industrial) operating junction temperature and offers 100 MHz+ internal performance for typical designs. The EP1K30TC144-1N uses a continuous, segmented routing architecture with 4-input look-up table (LUT) logic elements that include dedicated carry chains for fast arithmetic. This LUT-based fabric gives designers flexibility to implement any logic function while the embedded array blocks provide efficient on-chip memory for FIFOs, ROM, and dual-port RAM structures. Typical applications include telecommunications interface cards, industrial control boards, low-cost prototyping platforms, PCI bridge logic, legacy system upgrades, educational digital logic labs, and consumer-electronics glue logic. The 102 available I/O pins and 1,728 LEs make it suitable for designs needing moderate logic density with low power and cost. When designing with the EP1K30TC144-1N, ensure the Quartus II (or legacy MAX+PLUS II) design toolchain supports this mature part. JTAG programming is recommended for production; the configuration bitstream is volatile and must be loaded at every power-up from a configuration memory or a host processor. 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
EP1K30TC144-2

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.

EP1K30TC144-2N - 30K Gate ACEX-1K FPGA 144-TQFP | Intel / Altera
EP1K30TC144-2N

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

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.
