EPF10K30AQC208-3

EPF10K30AQC208-3 - 30K Gates FLEX-10KA FPGA, 208-PQFP | Altera

The Altera EPF10K30AQC208-3 is a member of the FLEX-10KA family of Field Programmable Gate Arrays (FPGAs) featuring 30,000 gates, 1,728 logic cells, 12,288 bits of embedded memory, and 147 user I/Os, housed in a 208-pin Plastic Quad Flat Pack (PQFP) package. It is fabricated on a 0.3 µm CMOS process, operates from a 3.3 V core supply, and is specified for commercial temperature grades with a -3 speed grade. An FPGA (Field Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that can be re-programmed to implement arbitrary digital logic. Within the broader taxonomy, the FLEX-10KA belongs to the SRAM-lookup-table-based FPGA family, sitting between simple CPLDs and modern high-density FPGAs. It supports System-on-a-Programmable-Chip (SOPC) integration by combining embedded array blocks (EABs) for megafunctions such as efficient memory and specialized logic functions with general-purpose logic, allowing designers to implement microcontrollers, DSP functions, and glue logic on a single device. Key features of the EPF10K30AQC208-3 include 216 Logic Array Blocks (LABs) organized as 24 Logic Elements (LEs) per LAB, embedded array blocks for memory and DSP-style functions, MultiVolt I/O support for interfacing with 5.0 V, 3.3 V, 2.5 V, and 1.8 V logic without external level shifters, JTAG-based in-system programmability via IEEE 1149.1, PCI pull-up clamping diodes, slew-rate control, and open-drain output options configurable pin-by-pin through Altera logic options. The device uses Altera's Look-Up Table (LUT)-based architecture with continuous FastTrack routing, delivering predictable timing closure and supporting frequencies up to 125 MHz in this speed grade. It is supported by the legacy Altera MAX+PLUS II and Quartus design flows, although modern Quartus releases no longer include this family, and designers using this device typically retain the original MAX+PLUS II toolchain or maintain pre-generated programming files. Typical applications include telecommunications line cards, industrial control and factory automation, legacy PCI interface bridges, and embedded control logic that requires moderate gate counts with on-chip memory. The 208-PQFP package also makes the EPF10K30AQC208-3 a common choice for board-level prototyping where fine-pitch BGA packages are not practical. When designing with this device, attention should be paid to the MultiVolt I/O configuration: VCCINT must be tied to 3.3 V while VCCIO can be set independently to support mixed-voltage buses. Configuration via JTAG or a serial/configuration EPROM must also be considered; the device is volatile (SRAM-based) and loses configuration on power-down, so an external configuration memory is required for production designs. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the Altera datasheet alone.

EPF10K30AQC208-3N

EPF10K30AQC208-3N - 30K Gates FLEX 10KA FPGA, 208-PQFP | Intel / Altera

The Intel / Altera EPF10K30AQC208-3N is a member of the FLEX 10KA family of SRAM-based Field-Programmable Gate Arrays (FPGAs) integrating 30,000 typical gates, 1,728 logic elements (cells) and 12,288 bits of embedded memory into a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. Built on a 0.3 µm CMOS process and supplied from a 3.3 V core, the device delivers up to 125 MHz of system performance and exposes 147 user I/O pins for digital interfacing. The “-3” speed grade and the “N” lead-free suffix confirm commercial temperature operation and Pb-free assembly, while the “QC208” package code denotes the 208-pin QFP outline used across the FLEX 10KA density range. A Field-Programmable Gate Array (FPGA) is a semiconductor device whose logic function is defined by user-loaded configuration memory rather than hard-wired mask layers. FPGAs sit in the programmable-logic hierarchy between simple Complex Programmable Logic Devices (CPLDs) and high-density Application-Specific Integrated Circuits (ASICs), giving engineers hardware-reconfigurable glue logic, datapath acceleration, and bus-interface bridging without any NRE charges. The FLEX 10KA family was Intel / Altera’s first generation to embed dedicated array blocks (EABs) for efficient RAM and DSP megafunctions, marking the transition from pure glue logic to System-on-a-Programmable-Chip (SOPC) integration. Key features of the EPF10K30AQC208-3N include 216 Logic Array Blocks (LABs) organised in rows and columns, embedded array blocks for dual-port RAM and ROM, MultiVolt I/O allowing mixed-voltage interfacing on the same die, pin-controlled PCI-clamping diodes, slew-rate control, and open-drain output options. The PLICE antifuse-style configuration scheme is replaced here by an SRAM configuration cell, supporting in-system reconfigurability via the serial or parallel configuration port. The exposed MultiVolt interface simplifies bridging between 3.3 V cores and 5.0 V or 2.5 V peripherals. Typical applications include PCI bus controllers, telecommunications line cards, industrial glue logic, protocol bridging (UART, I²C, SPI bridges), legacy ASIC replacement, and parallel DSP datapath prototyping. The combination of 12 Kbit embedded memory, 147 I/Os and 125 MHz Fmax makes it well-suited to mid-density control-plane designs where cost per gate dominates over raw performance. When designing with this part, allocate the configuration PROM or microcontroller interface early in the schematic because FLEX 10KA devices do not retain their configuration when power is removed. The MultiVolt VCCIO rail must be tied before or simultaneously with VCCINT to avoid latch-up. Use the Quartus / MAX+PLUS II Legacy device libraries and observe the 208-PQFP thermal envelope (θJA ≈ 35 °C/W typical) when calculating airflow in dense line-card layouts. This page synthesises distributor pricing, drop-in same-package alternatives and practical design notes that go beyond the marketing datasheet, so procurement engineers and FPGA designers can make a confident selection.

EPF10K30AQC240-1

EPF10K30AQC240-1 - 30K FLEX-10KA FPGA, 240-PQFP | Intel/Altera

The Intel (formerly Altera) EPF10K30AQC240-1 is a FLEX-10KA family Field Programmable Gate Array (FPGA) integrating 30,000 typical gates, 1,728 logic elements, and 12,288 bits of embedded SRAM in a 240-pin Plastic Quad Flat Pack (PQFP / BFQFP) package. Built on a 0.42 µm CMOS process, the device offers 189 user I/O pins, a 0.6 ns propagation delay, and supports commercial-grade operation from 0 °C to 70 °C with a 3.3 V core supply. What is an FPGA? A Field Programmable Gate Array is a semiconductor integrated circuit composed of an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that can be electrically reconfigured to implement custom digital logic. FPGAs occupy a tier between fixed-function ASICs (high NRE cost, no flexibility) and discrete logic/gate arrays (limited density). The FLEX-10KA family specifically introduced an embedded array block (EAB) that combines look-up-table-based logic with dedicated SRAM blocks, enabling System-on-a-Programmable-Chip (SOPC) integration - the industry's first such hybrid architecture. FPGAs belong to the broader programmable logic device family, alongside CPLDs (Complex Programmable Logic Devices) and SPLDs (Simple PLDs). Key features include 216 logic array blocks (LABs) organized across the fabric, dedicated carry chains for arithmetic, and a JTAG-compliant IEEE 1149.1 boundary-scan interface. The architecture supports 5-V tolerant I/O on selected variants and offers true dual-port RAM blocks (EABs) configurable from 256 × 8 to 2,048 × 1. Fast-Track interconnect provides predictable, deterministic routing with a fixed delay across the device, simplifying timing closure in legacy Quartus II design flows. Typical applications span telecommunications line cards, industrial control and motor drive front-ends, legacy networking equipment, and embedded instrumentation where mid-range logic density and SRAM integration are required without the overhead of a soft-core processor. The device is fully supported by Altera Quartus II (legacy releases) and MAX+PLUS II toolchains, which remain in use across long-lifecycle industrial and defense programs. Designers should evaluate the device's 0.6 ns pin-to-pin logic delay against system timing budgets, and confirm 3.3 V core / 5 V tolerant I/O compatibility with surrounding logic. Because the FLEX-10KA family is no longer recommended for new designs, an end-of-life migration plan to Cyclone IV/V or MAX 10 is advisable for ongoing programs. This page consolidates distributor pricing, parametric comparisons, and legacy support notes not found in the original datasheet alone.

EPF10K30AQC240-1N - 30K-Gate FLEX-10KA FPGA, 240-PQFP | Intel

The Intel (formerly Altera) EPF10K30AQC240-1N is a 30,000-gate FLEX-10KA family Field-Programmable Gate Array (FPGA) housed in a 240-pin Power Quad Flat Pack (PQFP/BFQFP) package. It integrates 1,728 logic elements (LEs) across 216 Logic Array Blocks (LABs) with 12,288 bits of embedded SRAM, providing approximately 30K typical gates of logic capacity for mid-complexity digital designs. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that combines configurable logic blocks, programmable interconnects, and I/O cells on a single die. The FLEX-10KA family is the industry's first embedded PLD family, providing System-on-a-Programmable-Chip (SOPC) integration with embedded array blocks (EABs) for memory-intensive functions such as FIFOs, RAM, and ROM. FPGAs sit within the broader hierarchy of programmable logic -> PLD -> digital IC -> semiconductor. Key specifications include 189 user I/Os, a maximum internal frequency of approximately 166.67 MHz, a propagation delay of 0.6 ns, and operation from a 3.3 V supply. The device is fabricated on a 0.3 µm CMOS process and supports the commercial temperature grade (0 °C to 70 °C). It features built-in low-skew clock distribution trees, FastTrack Interconnect for predictable interconnect delays, and tri-state emulation that supports in-system debugging. The EPF10K30AQC240-1N is built on Altera's Look-Up Table (LUT)-based architecture with continuous FastTrack routing, making timing closure more predictable than segmented interconnect schemes. The embedded array blocks (EABs) can each implement 2,048 bits of RAM, enabling efficient on-chip memory for DSP-style data paths and glue-logic functions. Typical applications include telecommunications glue logic, industrial control interfaces, legacy system prototyping, and embedded controller replacement where low-to-moderate gate counts are needed. Designers often select this part for upgrading older discrete-TTL designs into a single programmable device. When designing with this FPGA, ensure your JTAG chain handles the device's boundary-scan and configuration requirements, and verify timing closure at the -1 speed grade in your synthesis tool. Quiescent power is minimized by tying unused I/Os to a defined logic level through the Quartus pin assignment file.

EPF10K30AQC240-2N

EPF10K30AQC240-2N - 30K Gate FLEX-10KA FPGA | Intel / Altera

The Intel / Altera EPF10K30AQC240-2N is a 30,000-gate FLEX-10KA series Field Programmable Gate Array (FPGA) with 1,728 logic cells, 12,288 bits of embedded array memory, and 189 user I/O pins, housed in a 240-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. It operates from a 3.3V supply, is fabricated on a 0.3 µm CMOS process, and supports an internal maximum frequency of 142.86 MHz at commercial temperature grade (0 °C to 70 °C). An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the density of gate arrays with user programmability. FPGAs sit at the top of the programmable logic hierarchy — above SPLDs and CPLDs — and are used to implement arbitrary digital logic, glue logic, bus interfaces, and signal processing pipelines. The FLEX-10KA family specifically introduced an embedded array block (EAB) that holds dedicated SRAM blocks for memory functions, allowing the device to act as a System-on-a-Programmable-Chip (SOPC) building block. Key features of the EPF10K30AQC240-2N include 216 Logic Array Blocks (LABs), a built-in low-skew clock distribution tree, FastTrack® Interconnect continuous routing structure for predictable interconnect delays, tri-state emulation for board-level testing, and 100 % functional factory testing. The device supports both 3.3 V and 5.0 V I/O operation through selectable I/O standards, simplifying mixed-voltage system integration with legacy logic families. The device architecture combines logic elements grouped into LABs, EAB-based memory, and a hierarchical interconnect network. The embedded array blocks are configurable as wide SRAM blocks, while the logic array blocks contain 8 logic elements each. This hybrid architecture makes the EPF10K30AQC240-2N well-suited to designs that need both random logic and small-to-medium memory functions on a single chip. Typical applications include telecom line cards, industrial control, glue logic for microprocessor systems, custom peripheral controllers, prototype ASIC development, and legacy system maintenance where the original FLEX-10KA design must be reproduced. When designing with this FPGA, engineers should plan for the older 0.3 µm CMOS process — it draws higher quiescent current than modern 65 nm / 28 nm FPGAs, and the 240-pin PQFP is a through-hole-friendly surface-mount package requiring careful thermal management at higher toggle rates.

EPF10K30AQC240-3 - 30K-Gate FLEX-10KA FPGA, 240-PQFP | Altera

The Altera EPF10K30AQC240-3 is a member of the FLEX-10KA family of SRAM-based FPGAs, delivering approximately 30,000 usable gates, 1,728 logic elements (cells), and 12,288 bits of embedded RAM in a 240-pin Plastic Quad Flat Pack (PQFP) package. According to the FLEX-10KA datasheet, this device is fabricated on a 0.3 µm CMOS process and operates from a nominal 3.3 V supply (3.0 V min, 3.6 V max), with 189 user I/O pins arranged in 216 logic array blocks (LABs). A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs), programmable interconnect, and programmable I/O cells. FPGAs belong to the broader category of programmable logic devices (PLDs), which sit hierarchically below ASICs in the digital design taxonomy. Unlike an ASIC, an FPGA can be reconfigured in the field after manufacture, making it ideal for prototyping, low-volume production, and designs that require post-deployment updates. The FLEX-10KA series was one of the first commercially successful "System-on-a-Programmable-Chip" (SOPC) families, integrating lookup-table-based logic with embedded array blocks (EABs) that can implement RAM, ROM, or multiplier functions. Key features of the EPF10K30AQC240-3 include 216 LABs, 189 programmable I/Os, 12,288 bits of embedded SRAM, a typical internal operating frequency around 125 MHz, and multi-voltage I/O support compatible with 3.3 V and 5 V interfaces. The "-3" speed grade designates a faster bin relative to the -1 and -2 grades, and the "C" in the part number indicates the commercial 0 °C to 70 °C temperature range. Architecturally, the FLEX-10KA device combines a fine-grained logic fabric (each LAB contains eight logic elements) with coarse-grained EABs of 2,048 bits each, allowing designers to balance random logic against memory-intensive functions in the same die. The 240-PQFP footprint (also referred to as 240-BFQFP or FQFP-240) is a gull-wing surface-mount package, suitable for reflow assembly and rework. Typical applications for the EPF10K30AQC240-3 include glue logic and bus bridging in industrial controllers, custom I/O expansion for legacy 3.3 V systems, prototype ASIC replacement, communication protocol bridging (UART, SPI, I2C, parallel buses), and educational/development platforms for HDL designers. The wide 5 V-tolerant I/O bank simplifies interfacing with TTL-era peripherals. When designing with this device, ensure that the Quartus or MAX+PLUS II toolchain version supports the FLEX-10KA family, as newer Quartus releases have dropped legacy device support. Provide clean 3.3 V power with adequate decoupling near each VCC/VCCIO pin pair, and respect the JTAG programming pinout for in-system configuration.

EPF10K30AQI208-3 - FLEX 10KA FPGA, 30K Gates, 208-PQFP | Altera

The Altera (now Intel) EPF10K30AQI208-3 is a member of the FLEX 10KA family of Field-Programmable Gate Arrays, offering 30,000 typical gates, 1,728 logic elements (LEs), 12,288 RAM bits, and 147 user I/Os, all housed in a 208-pin Power Quad Flat Pack (PQFP/BFQFP) package with industrial temperature grade. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows designers to configure digital logic blocks and interconnects after manufacture. The FLEX 10KA family was Altera's first embedded programmable logic family delivering System-on-a-Programmable-Chip (SOPC) integration, combining a logic array with an embedded array block (EAB) used for memory, multipliers, or specialized functions. Architecturally, an FPGA sits within the broader category of programmable logic -> logic IC -> integrated circuit -> semiconductor. The EPF10K30AQI208-3 is fabricated on a 0.30 µm CMOS process and operates from a 3.3 V core supply. It supports a maximum internal frequency of 125 MHz and is designed for 3.3 V PCI-compliant I/O with built-in Joint Test Action Group (JTAG) boundary-scan test circuitry compliant with IEEE Std. 1149.1-1990. The industrial temperature grade (-40 °C to +85 °C) makes this part suitable for harsher environments than the commercial-only EPF10K30AQC208-3 variant. Typical applications include telecommunications line cards, industrial control and factory automation, glue logic replacement for ASICs, PCI interface bridging, and legacy system upgrades where a 3.3 V, 5 V-tolerant I/O FPGA is required. Designers often select the FLEX 10KA family for new system bring-up because of its mature toolchain (Quartus), predictable timing, and long-term availability through the Altera-to-Intel transition. When designing with the EPF10K30AQI208-3, plan I/O assignments carefully because the PQFP package has limited power/ground pin count, which can constrain signal integrity for high-speed designs. Use the IEEE 1149.1 boundary-scan chain for board-level testing and consider the EPF10K30EQC208-3 (FLEX 10KE) as a drop-in migration path when higher performance or more LE capacity is needed.

EPF10K30AQI208-3N - 30K Gates FLEX-10KA FPGA 147 I/O 208-PQFP | Altera

The Intel (formerly Altera) EPF10K30AQI208-3N is a member of the FLEX-10KA embedded programmable logic family, delivering 30,000 gates, 1,728 logic cells, and 12,288 bits of embedded SRAM in a 208-pin Plastic Quad Flat Pack (PQFP / BFQFP) surface-mount package. It provides 147 user I/O pins, operates from a 3.3 V core supply, and supports MultiVolt I/O for interfacing with 2.5 V / 3.3 V / 5 V logic rails. The device is built on a 0.30 µm CMOS SRAM process and targets glue-logic, bus-interface, and System-on-a-Programmable-Chip (SOPC) bridge functions where deterministic pin-to-pin timing is required. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) containing an array of configurable logic blocks (LABs), programmable interconnect, and I/O cells that the designer can re-program in-system. Within the broader taxonomy, an FPGA sits under Programmable Logic -> Logic ICs -> Integrated Circuits. FPGAs differ from CPLDs in offering larger register-rich logic capacity and embedded memory, while sharing with CPLDs the ability to implement arbitrary digital state machines, glue logic, and bus bridges without a custom ASIC. Key features of the EPF10K30AQI208-3N include 216 Logic Array Blocks (LABs), per-pin slew-rate control, PCI pull-up clamping diodes, and open-drain output options, all configured via Altera logic options in the MAX+PLUS II / Quartus toolchains. The device supports in-system programmability via an industry-standard passive serial (PS) or passive parallel asynchronous (PPA) configuration interface, allowing field upgrades without removing the part. Embedded array blocks (EABs) provide efficient on-chip memory for FIFO, ROM, and dual-port RAM functions. The EPF10K30AQI208-3N uses a four-level hierarchical interconnect structure that combines fast row/column channels with local LAB interconnect, delivering predictable timing closure for designs in the 40-80 MHz internal performance range. The 12,288-bit embedded SRAM (organized as 6 EABs of 2,048 bits each) is suitable for small buffers, register files, and look-up-table based arithmetic. MultiVolt I/O lets each output bank independently run at 2.5 V, 3.3 V, or 5 V while the core stays at 3.3 V, simplifying mixed-voltage designs. Typical applications include legacy telecom line-card glue logic, industrial control backplane bridges, PCI bus interface controllers, parallel-to-serial protocol converters, and instrumentation front-ends that need deterministic timing. Because the part is mature and well-documented, it is also common in long-lifecycle defense, medical, and aerospace programs that have already validated the silicon in their BOM. A critical design consideration when migrating from the EPF10K30AQI208-3N is that the FLEX-10KA family is no longer in active production and the part is now sourced from the obsolete / last-time-buy channel. New designs should consider Cyclone IV or Cyclone V equivalents unless pin-for-pin compatibility is mandatory. Existing boards can be re-qualified with EPF10K30AQC208-3N (commercial grade) or EPF10K30AQC208-1N (slower speed grade) as drop-in 208-PQFP substitutes with identical pinout.

EPF10K30AQI240-1 - FLEX 10KA FPGA, 30K Gates, 240-PQFP | Altera

The Altera (now Intel) EPF10K30AQI240-1 is a FLEX 10KA family Field Programmable Gate Array (FPGA) housed in a 240-pin Plastic Quad Flat Pack (PQFP) package, offering approximately 30,000 ASIC-equivalent gates and 1,728 logic elements (LEs) with embedded array blocks. It supports up to 189 user I/O lines, 4 dedicated inputs and 193 total inputs, operates at a maximum clock frequency of 769.23 MHz with a propagation delay of 11 ns, and runs on a 3.3 V core supply in 0.42 um CMOS SRAM technology. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be electrically reconfigured by the designer after manufacturing. The FLEX 10KA family belongs to the hierarchy FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit, and combines a fine-grained Look-Up Table (LUT)-based logic fabric with coarse-grained Embedded Array Blocks (EABs) that can be used as on-chip RAM, ROM, or wide-gate functions. This hybrid architecture placed the FLEX 10KA at the boundary between traditional PLDs and modern FPGAs in the mid-1990s and remains a textbook reference for embedded-array design. Key features of the EPF10K30AQI240-1 include 24,576 RAM bits distributed across EABs, 4 dedicated fast inputs plus 4 dedicated fast clock networks, multiVolt I/O supporting 5.0 V, 3.3 V and 2.5 V interface levels, in-system programmability through the IEEE 1149.1 (JTAG) boundary-scan chain, and registered output functions with mixed output options. The -1 speed grade denotes the slowest of three FLEX 10KA speed bins, trading fMAX for lower cost. Technically, the device is built on a 0.42 um four-metal-layer CMOS SRAM process, which makes the configuration volatile: the bitstream must be loaded from an external EEPROM or microcontroller on every power-up. The 189 I/O pins are organized into per-bank VCCIO rails, allowing the part to bridge 5 V peripherals and 3.3 V ASICs without level shifters. Industrial temperature grade operation from -40 C to +85 C makes it suitable for harsh environments. Typical applications for the EPF10K30AQI240-1 include glue logic replacement, industrial control and instrumentation front-ends, telecommunications backplane bridging, PCI bus controllers, and legacy ASIC prototyping. The wide I/O count is especially attractive for bus-aggregation designs where dozens of address, data, and control signals must be merged into a single high-speed interface. When designing with this part, allocate a ByteBlaster or BitBlaster download cable for JTAG programming and reserve 4-6 dedicated configuration pins. Decoupling must follow the FLEX 10KA reference design: at minimum, one 0.1 uF X7R per VCC pin and one bulk 33 uF tantalum on the 3.3 V core rail. Designers targeting new designs should evaluate Cyclone or Cyclone II as modern pin-compatible drop-in alternatives, since the FLEX 10KA is now an NRND/EOL product family.

Intel EPF10K30ATC144-1N is a member of the FLEX 10KA family of Field-Programmable Gate Arrays (FPGAs) that delivers 30,000 typical gates, 1,728 logic elements, and 12,288 bits of embedded memory in a 144-pin LQFP (TQFP) surface-mount package. The device is built on a 0.30 micrometer CMOS process, operates from a 3.3 V core supply, and is specified for commercial temperature grade (0 to 70 C). It provides 102 user I/O pins and integrates 216 Logic Array Blocks (LABs), making it suitable for glue-logic, bus-interface, and mid-density state-machine designs. An FPGA (Field-Programmable Gate Array) is a type of integrated circuit whose logic function is defined after manufacturing by the user. FPGAs sit within the broader programmable logic hierarchy that includes Simple PLDs (SPLDs), Complex PLDs (CPLDs), and FPGAs, and they are widely used as an alternative to ASICs for low- to mid-volume designs. The FLEX 10KA family was Altera's first device to combine a Look-Up Table (LUT)-based logic fabric with an embedded array block (EAB) that could implement dual-port RAM, ROM, or multiplier functions - the original embodiment of the System-on-a-Programmable-Chip (SOPC) concept. Key features of the EPF10K30ATC144-1N include 1,728 logic elements arranged across 216 LABs, 12,288 RAM bits distributed in 12 EABs of 2,048 bits each, a maximum internal frequency of approximately 166.67 MHz, and a pin-to-pin propagation delay as low as 0.6 ns. The device supports in-system configuration via a serial or parallel configuration interface and is compatible with the MAX+PLUS II and Quartus (legacy) design environments. It is lead-free and supplied in JEDEC-standard TQFP-144 plastic packaging with a body size of 20 mm by 20 mm and a 0.5 mm lead pitch. Typical applications for the EPF10K30ATC144-1N include legacy industrial control boards, telecommunications glue logic, custom peripheral controllers for PCI and ISA bus systems, and design-replacement of older discrete TTL or CMOS logic. Designers continue to specify the FLEX 10KA family in long-lifecycle systems where re-qualification cost outweighs the benefit of migrating to a newer FPGA series. The combination of EAB memory and a LUT fabric also made the device popular for prototyping custom datapath functions before tape-out. When designing with this part, note that the device is now in a mature lifecycle phase; supply is increasingly limited to distributor inventory and broker stock. Engineers should confirm long-term availability through the manufacturer's product change notifications and consider EPF10K30Axxxx variants in different packages (240-pin QFP, 208-pin QFP) if a PCB redesign is acceptable.

The Intel / Altera EPF10K30ATC144-2N is a member of the FLEX 10KA family of SRAM-based Field-Programmable Gate Arrays (FPGAs) delivering 30,000 typical gates (17,200 usable gates) and 1,728 logic elements in a 144-pin TQFP (thin quad flat pack) package. It is built on a 0.3 µm CMOS process and operates from a 3.0 V to 3.6 V supply, with 102 user I/O pins, 12,288 bits of embedded RAM, and 216 logic array blocks (LABs). The 'A' suffix denotes the 3.3 V supply generation; 'C' indicates the commercial 0 °C to 70 °C temperature range; '144' is the pin count; and '-2N' specifies the speed grade and lead-free, NiPdAu lead finish. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the high integration of an ASIC with the flexibility of software-reconfigurable logic. In the system hierarchy, the FLEX 10KA sits between traditional CPLDs and high-density SRAM FPGAs such as APEX and Cyclone. It is widely used for glue logic, bus interface bridging, and moderate-complexity state-machine designs where re-programmability in-system is required. Key features include 1728 logic elements, 12,288 RAM bits distributed across embedded array blocks (EABs), in-system programmability via an IEEE 1149.1 (JTAG) interface, multi-volt I/O support (2.5 V or 3.3 V), and 102 maximum user I/O pins. The device is supported by the legacy Altera MAX+PLUS II and Quartus design toolchains, enabling designers to import, simulate, and re-target existing FLEX 10K designs without modification. The FLEX 10KA architecture combines a fine-grained logic element fabric with coarse-grained Embedded Array Blocks (EABs) of 2 Kbits each, allowing designers to instantiate RAM, ROM, or product-term logic without wasting LE resources. Internal global clock networks and a peripheral control bus simplify high-pin-count designs in the 144-TQFP footprint. Typical applications include industrial control and factory automation glue logic, telecommunications line-card interface bridging, legacy data-acquisition front ends, and drop-in replacements for end-of-life ASICs. The commercial temperature grade makes it suitable for indoor and laboratory equipment rather than automotive under-hood or extended industrial deployments. When designing with this part, use the MAX+PLUS II or Quartus II toolchain to generate configuration bitstreams in .sof or .pof format and program the device through the JTAG port using a ByteBlaster or USB-Blaster download cable. Pay attention to the I/O bank supply rails - 3.3 V banks must not exceed 4.0 V during hot-plug events, otherwise input clamps can latch-up.

It integrates 1,728 logic elements and 12,288 RAM bits, providing System-on-a-Programmable-Chip (SOPC) capability through its embedded array architecture. A Field Programmable Gate Array (FPGA) is a reconfigurable semiconductor device containing an array of programmable logic blocks, configurable interconnect, and I/O cells that can be customized by the designer to implement arbitrary digital circuits. The FLEX 10KA family specifically pioneered embedded memory blocks within the FPGA fabric, combining lookup-table (LUT)-based logic with on-chip dual-port RAM, enabling system-on-chip integration without external memory components for many designs. Key features of the EPF10K30ATC144-3 include 102 user I/O pins, 216 Logic Array Blocks (LABs), and operation from a 3.3V core supply. The device supports CMOS I/O standards and provides a maximum internal frequency of 80 MHz with a propagation delay of approximately 0.6 ns per logic element. The embedded array blocks (EABs) implement true dual-port RAM, ROM, or arithmetic functions, distinguishing FLEX 10KA from earlier FLEX 10K devices. The device's SRAM-based configuration memory allows unlimited reconfiguration in-circuit. Its architecture is organized as rows and columns of LABs interconnected by a continuous, high-performance routing network.

EPF10K30ATI144-1 - FLEX 10KA FPGA 30K Gates 144-TQFP | Intel

The Intel (Altera) EPF10K30ATI144-1 is a member of the FLEX 10KA embedded programmable logic device family, providing 30,000 typical gates in a 144-pin TQFP (Thin Quad Flat Pack) industrial-temperature package. The device integrates 1,728 logic elements, 216 logic array blocks (LABs), and 12,288 bits of embedded memory across a CMOS SRAM-based architecture with 102 user I/O pins. It operates from a 3.0 V to 3.6 V supply (nominal 3.3 V) and is offered in the -1 speed grade for cost-sensitive designs. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows engineers to implement custom digital circuits after PCB fabrication. The FLEX 10KA family belongs to the broader category hierarchy of FPGA -> programmable logic device -> digital IC -> semiconductor, and was the industry-first embedded programmable logic family to provide System-on-a-Programmable-Chip (SOPC) integration through its dedicated embedded array blocks (EABs). This combination of logic and embedded memory enabled designers to build complete subsystems including controllers, datapaths, and small microprocessors on a single programmable die. Key features of the EPF10K30ATI144-1 include 1,728 logic cells, 216 LABs, 12 Kbit embedded array memory, 102 user I/Os, and 4 dedicated inputs, all supplied through a 3.3 V single-rail interface. The device is housed in a 144-pin TQFP surface-mount package suitable for standard reflow assembly. The -1 speed grade offers the slowest timing in the FLEX 10KA lineup but provides the lowest cost point, making it attractive for prototyping, education, and legacy production designs where maximum clock rate is non-critical. Architecturally, the FLEX 10KA combines a fine-grained logic fabric with coarse-grained embedded array blocks, allowing designers to trade off random logic density against memory/RAM capacity on a per-design basis. Each LAB contains eight logic elements, each with a 4-input look-up table, a programmable flip-flop, and dedicated carry and cascade chains for high-speed arithmetic and wide fan-in functions. The embedded array blocks provide true dual-port RAM, ROM, and FIFO primitives up to 2 Kbit per block with parity support, removing the need for external SRAM in many glue-logic applications. Typical applications include industrial control and factory automation, telecommunications glue logic, legacy peripheral controllers, ASIC prototyping, low-volume production bridges, and educational FPGA platforms. Designers migrating from discrete 74-series TTL or PAL/GAL devices frequently chose the EPF10K30A family because it consolidated dozens of small logic functions onto a single re-programmable part. In production the device supports in-system programmability through the IEEE 1149.1 JTAG interface and is configured at power-up from a serial PROM such as the EPC2 or EPC8 configuration device. When designing with this FPGA, allocate sufficient printed-circuit-board area for the configuration PROM and the JTAG header. The 144-pin TQFP has a 0.5 mm pitch and requires careful fan-out; route all global clock and high-fanout signals on inner PCB layers with controlled impedance. For signal integrity, keep clock traces short and isolated, and provide 0.1 uF decoupling on every VCCIO/VCCINT pin pair. Designers must also respect the device's in-rush current during configuration and ensure the 3.3 V rail ramps within the datasheet-specified 100 us window. This page synthesizes distributor availability, parametric specifications, drop-in compatible parts from the same FLEX 10KA family, and practical design notes for the EPF10K30ATI144-1, providing information beyond a single manufacturer datasheet.

EPF10K30ATI144-2

EPF10K30ATI144-2 - 30K-Gate FLEX 10KA FPGA, 144-TQFP | Altera

The Altera (Intel Programmable Solutions Group) EPF10K30ATI144-2 is a member of the FLEX 10KA family of CMOS SRAM-based Field-Programmable Gate Arrays (FPGAs) integrating approximately 30,000 typical gates, 1,728 logic elements, and 12,288 RAM bits in a 144-pin Plastic Quad Flat Pack (TQFP) package. The -2 speed grade and 'I' (industrial) temperature suffix make this device a moderate-performance, extended-temperature variant aimed at glue-logic, bus-interface, and state-machine consolidation designs. An FPGA is a semiconductor device built around a matrix of configurable logic blocks (CLBs) connected through programmable interconnect and surrounded by programmable I/O cells. Unlike ASICs, FPGAs are manufactured in volume and customized at the customer's bench via a configuration bitstream loaded into on-chip SRAM at power-up. The FLEX 10KA family extends the original FLEX 10K architecture by adding embedded array blocks (EABs) that implement dedicated on-chip memory, doubling usable on-chip RAM to 12,288 bits and enabling true single-chip implementations of small FIFOs, register files, and lookup tables alongside general logic. Key features of the EPF10K30ATI144-2 include 246 user I/O pins distributed across six I/O banks, an embedded array of 12 EABs delivering up to 12,288 bits of fast synchronous RAM, JTAG-based IEEE 1149.1 boundary-scan test support, multi-volt I/O compatibility with 5.0 V, 3.3 V, and 2.5 V interfaces, and in-system programmability through the Altera MAX+PLUS II or Quartus development flow. The 144-pin TQFP footprint offers a compact, low-cost PCB integration path. Typical applications span industrial control, glue logic for microprocessor and DSP subsystems, peripheral and bus interfacing, low-volume prototyping bridges to ASIC migration, and telecommunication line-card glue logic. Compared with later Cyclone families, the FLEX 10KA uses older 0.42 µm CMOS, four-metal-layer process technology and consumes higher static current; it remains attractive only for legacy board respins, long-life industrial platforms, and cost-sensitive retrofits. When designing with this device, provide a clean 5.0 V core supply, decoupling with at least one 0.1 µF ceramic capacitor per supply supply pin, and a configuration PROM or microcontroller to load the bitstream at power-up. Verify all JTAG signals are pulled to defined states during board bring-up to prevent accidental reprogramming in noisy environments. This page synthesizes verified distributor availability, same-family drop-in alternatives, lifecycle context, and practical design guidance not found on a single distributor listing, helping engineers rapidly assess whether the EPF10K30ATI144-2 is still viable for their long-life program.

EPF10K30ATI144-3N

EPF10K30ATI144-3N - 30K Gate FLEX-10KA FPGA, 102 I/O, TQFP-144

The Altera (now Intel) EPF10K30ATI144-3N is a member of the FLEX 10KA family of embedded programmable logic devices, delivering 30,000 typical gates, 1,728 logic cells, and 12,288 bits of embedded SRAM in a 144-pin TQFP surface-mount package. Operating from a 3.3 V core supply, the device provides 102 user I/O pins and supports system clock rates up to 125 MHz, targeting glue-logic, bus-interface, and low-to-mid density state-machine designs. What is an FPGA? A Field-Programmable Gate Array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the designer can wire up after manufacture to implement arbitrary digital circuits. FPGAs sit at the top of the programmable logic hierarchy (PLA -> CPLD -> FPGA) and offer higher density, richer memory, and faster I/O than CPLDs. The FLEX 10KA family pioneered the embedded-array concept: a "sea of gates" fabric combined with dedicated True-Linked Dual-Port RAM blocks, enabling system-on-a-programmable-chip (SOPC) integration well before hard processor cores were common. Key features include 216 Logic Array Blocks (LABs), per-LAB ten Logic Elements (LEs), embedded SRAM organized in 12 EABs of 2,048 bits each, in-system programmability via JTAG (IEEE 1149.1), four Low-Voltage Differential Signaling (LVDS)-capable I/O banks, and JTAG-based boundary-scan test. The -3N speed grade denotes a commercial-temperature device with the slowest of the FLEX 10KA speed bins, optimized for power efficiency rather than maximum fMAX. Architecturally, each LE contains a 4-input look-up table (LUT), a programmable register, carry-chain logic for fast adders, and a cascade chain for wide fan-in functions. The EAB blocks provide dual-port RAM or ROM up to 16x8 bits per block, ideal for FIFO buffers, register files, and look-up-table waveform generation. Typical applications include PCI bus interfaces, glue logic for microprocessor/microcontroller systems, custom peripheral controllers in telecom line cards, industrial control PLCs, and prototype ASIC replacement. The 102 I/Os comfortably support 32-bit dataplanes with parity or modest 64-bit buses. For new designs a Cyclone or MAX device is recommended; the FLEX 10KA family remains in service mainly for long-lifecycle industrial, medical, and military sustainment programs. Design considerations: plan for 3.3 V VCCINT and a separate VCCIO bank supply (3.3 V or 2.5 V depending on the I/O standard chosen). A 100 MHz or slower clock is realistic at the -3 speed grade; route clocks on a dedicated global clock network (CLK0..CLK3) and place a 0.1 µF decoupling cap on every VCC/VCCIO pin pair. This page consolidates distributor inventory, verified drop-in alternatives, and practical design notes for engineers sustaining legacy FLEX 10KA designs.

The Intel (formerly Altera) EPF10K30EFC256-1 is a member of the FLEX 10KE family of FPGAs delivering 30,000 typical gates and 1,728 logic elements in a 256-ball FineLine BGA package. It operates from a 2.5 V core supply (2.375 V to 2.625 V), supports 176 user I/O pins, and is graded for commercial temperature operation (0C to +70C). The FLEX 10KE series uses a 0.22 µm SRAM-based look-up table (LUT) architecture with embedded array blocks (EABs) for on-chip RAM and ROM, enabling integration of logic and memory in a single device. What is an FPGA? A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows engineers to implement custom digital circuits after PCB fabrication. Within the broader semiconductor taxonomy, an FPGA sits above fixed-function ASICs and below microcontrollers in terms of design flexibility: FPGAs can be reconfigured indefinitely via SRAM configuration memory, while microcontrollers execute software instructions. The FLEX 10KE family specifically introduced embedded array blocks (EABs), bridging the gap between pure logic FPGAs and earlier CPLDs that lacked dedicated memory. Key specifications include 24,576 logic cells (typical gate-equivalent), 1,728 flip-flops, embedded RAM organized in EABs, multi-volt I/O support, and JTAG-based in-system programmability via the ByteBlaster or BitBlaster configuration interface. The -1 speed grade provides a balance between cost and performance for general-purpose digital designs. The device architecture combines four-input LUT-based logic elements (LEs) with EABs that provide up to 2 Kbits of true dual-port RAM each, ideal for FIFO buffers, register files, and small lookup tables. Each LE contains a four-input LUT, a programmable flip-flop, and dedicated carry and cascade chains for high-speed arithmetic and wide fan-in functions. Typical applications include digital signal processing front-ends, telecommunications glue logic, industrial control interfaces, prototyping for ASIC designs, and legacy system maintenance where 5 V-tolerant multi-volt I/O is required. The 256-pin BGA package enables high I/O density on compact boards. When designing with this part, designers must supply a stable 2.5 V core and configure the device through a serial or parallel PROM at every power-up because SRAM-based FPGAs are volatile. JTAG boundary-scan support simplifies board test, while in-system programmability allows field upgrades without component replacement.

EPF10K30EFC256-1X - FLEX 10KE FPGA, 30K Gates, 256-BGA | Intel / Altera

The Intel (formerly Altera) EPF10K30EFC256-1X is a member of the FLEX 10KE family of SRAM-based FPGAs, providing 30,000 typical gates and 1728 logic elements (LEs) housed in a 256-ball FineLine BGA package. The device implements the FLEX 10KE architecture with 216 logic array blocks (LABs), 176 user I/O pins, and embedded array blocks (EABs) for distributed RAM and ROM. According to the Altera FLEX 10KE datasheet, the -1X speed grade offers the fastest commercial-grade timing with internal frequencies up to 250 MHz in 0.22 µm CMOS technology. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacture to implement custom digital logic functions. FPGAs sit within the broader programmable logic device (PLD) family, which also includes SPLDs and CPLDs. FPGAs like the FLEX 10KE sit at the top of the PLD hierarchy, providing the highest logic density and the richest interconnect. FPGAs occupy the position of programmable logic in the system hierarchy: ASIC < structured ASIC < FPGA < general-purpose microprocessor/DSP, with FPGAs delivering higher integration than CPLDs at lower NRE cost than full-cell ASICs. Key features include 24,576 bits of embedded memory distributed across EABs, four phase-locked loops (PLLs) for clock management, MultiVolt I/O supporting 2.5V/3.3V/5V interfaces, and in-system programmability via the IEEE 1149.1 JTAG interface. The 256-pin FBGA package provides a 17 mm x 17 mm body with 1.0 mm ball pitch, optimized for high-density surface-mount designs. Each EAB provides 4 Kbits of RAM, giving the device approximately 6 Kbits of usable RAM per EAB configuration. The FLEX 10KE architecture combines a fine-grained gate-array fabric (logic elements organized in LABs of 8 LEs each) with coarse-grained embedded array blocks for memory-intensive functions. The interconnect uses a hierarchical FastTrack routing structure with row and column channels, allowing predictable timing closure across typical logic utilization levels. The 0.22 µm CMOS process places the device in the legacy SRAM-FPGA tier that powered Altera's programmable logic roadmap from 1998 onwards. Typical applications include industrial control logic, telecommunications interface bridges, glue logic replacement, and prototype ASIC verification. The 176 user I/Os support abundant parallel buses, making the device suitable for legacy peripheral interfacing and custom state machines in test equipment. The combination of 30K gates and embedded memory also fits DSP pre/post-processing pipelines and protocol conversion cards in legacy industrial backplanes. When designing with this device, note that the FLEX 10KE family requires 2.5V core supply and supports 2.5V/3.3V/5V MultiVolt I/O. JTAG programming is mandatory because the SRAM configuration cell is volatile. The 256-BGA FineLine package demands careful PCB design with controlled-impedance routing and matched-length clock traces.

The Altera (Intel) EPF10K30EFC256-2 is a member of the FLEX 10KE family of FPGAs delivering approximately 30,000 system gates with 1,728 logic elements and 24,576 RAM bits in a 256-ball FineLine BGA package. It operates at a core voltage of 2.5 V (2.375 V to 2.625 V) and provides 176 user I/Os at up to 80 MHz internal frequency with 0.6 ns propagation delay, balancing logic density and I/O bandwidth for mid-complexity programmable designs. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs), programmable interconnect, and embedded memory that designers can re-configure in-system via SRAM lookup tables. Within the broader hierarchy, FPGAs sit alongside CPLDs (Complex Programmable Logic Devices) as the high-density branch of programmable logic; the FLEX 10KE family is a 0.22 um CMOS SRAM-based architecture that pioneered embedded array block (EAB) integration, foreshadowing modern System-on-a-Programmable-Chip (SoPC) designs. The EPF10K30E distinguishes itself with embedded dual-port RAM blocks, a 2.5 V core, and PCI compliance for bus-interface applications. Key features include 1728 logic elements, 24,576 RAM bits distributed across embedded array blocks (EABs), 216 logic array blocks (LABs), 176 usable I/O pins, and a peak operating frequency around 200 MHz according to family specifications. The FLEX 10KE architecture supports in-system programmability via the IEEE 1149.1 JTAG interface and passive serial configuration, enabling rapid prototyping. With SRAM-based configuration, the device must be reconfigured at each power-up using an external configuration PROM such as the EPC2 or EPC8 series. The EPF10K30E combines look-up-table (LUT)-based logic cells with embedded dual-port RAM, making it suitable for glue logic, bus interfaces, custom state machines, and moderate-density signal processing front-ends. Its embedded array blocks can implement FIFOs, ROM tables, and small DSP functions without consuming general-purpose logic. The 0.22 um CMOS process at 2.5 V core gives it better power efficiency than earlier 5 V FLEX 10K devices while preserving a familiar Quartus/MAX+PLUS II design flow. Typical applications include PCI bus interfaces, telecommunications line cards, industrial control logic, glue logic for ASIC/ASSP replacement, and prototype systems that need a moderate gate count and a high I/O count. The 176 I/O pins accommodate wide data buses and parallel peripheral interfaces, while the embedded RAM blocks enable protocol buffering and lookup-table acceleration. When designing with this FPGA, ensure the configuration PROM is sized appropriately for the bitstream and that JTAG chain integrity is validated before relying on in-system updates. Because the FLEX 10KE family is a mature, mature-generation part, lead-time risk is significant; verify distributor stock and lifecycle status before committing to a long-lifecycle design.

It is implemented in a 0.22 µm CMOS SRAM process and supports in-system configuration via a built-in serial configuration interface. The '2N' speed grade corresponds to a propagation delay of approximately 0.6 ns at the register-to-register path, with a commercial operating temperature range of 0 °C to +70 °C. A FLEX 10KE device is an SRAM-based FPGA that combines a logic array fabric with an Embedded Array Block (EAB), enabling true System-on-a-Programmable-Chip (SOPC) integration. Within the broader taxonomy, an FPGA is a programmable logic device (PLD) that sits alongside CPLDs in the digital IC hierarchy, and is itself a sub-family of the wider semiconductor category. FLEX 10KE parts were Altera's first family to embed true dual-port RAM blocks alongside distributed logic, an architecture later inherited by the APEX and Cyclone families. Key features include 246 user I/O pins, six dedicated clock input pins, support for multiple I/O standards (LVTTL, LVCMOS, PCI), 4-input look-up-table logic elements, and Cascade chains for high-fan-in functions. The device supports MultiVolt I/O for interfacing to 5.0 V, 3.3 V, and 2.5 V buses. In-system programmability is provided through the passive serial, active serial, or JTAG configuration schemes. Architecture is built on a SRAM-based array of logic elements arranged in Logic Array Blocks (LABs), each LAB containing eight LEs. The Embedded Array Blocks deliver up to 4 Kbits of true dual-port RAM with parity, allowing designers to instantiate memory blocks without consuming LE-based distributed RAM. FastTrack interconnect provides predictable routing delays across die corners. Typical applications include industrial glue logic, telecommunications backplane bridging, legacy PCI interface bridges, prototype ASIC emulation, and retro-computing or industrial-control retrofits where replacement of an obsolete ASIC is impractical. The BGA-256 footprint is shared with many newer Altera/Intel FPGAs, easing PCB migration. When designing with this part, note that it is a discontinued (Obsolete) component as of 2026-09-11 and should be sourced only from authorized aftermarket inventory. Designers should also plan for migration to an active FLEX 10KE variant or a Cyclone-equivalent device, since long-term availability is limited.

The Intel / Altera EPF10K30EFC256-2X is a member of the FLEX-10KE embedded programmable logic family, delivering 30,000 gates and 1,728 logic elements on a 0.22 µm CMOS process in a 256-ball FineLine BGA package measuring 17x17 mm. It operates from a 2.375 V to 2.625 V (2.5 V nominal) supply and supports user I/O counts up to 176 with a propagation delay as low as 0.6 ns and internal frequency up to 200 MHz. What is an FPGA? A Field-Programmable Gate Array (FPGA) is a programmable semiconductor that can be configured by the designer after manufacturing to implement custom digital logic. FPGAs sit in the broader hierarchy of programmable logic devices (PLDs) -> FPGAs -> SRAM-based FPGAs -> embedded-block FPGAs. The FLEX-10KE family pioneered embedded array blocks, integrating RAM and logic to enable System-on-a-Programmable-Chip (SOPC) designs that combine glue logic, FIFOs, and state machines on a single device. Key features include 24,576 bits of embedded SRAM distributed across EABs (Embedded Array Blocks), 216 Logic Array Blocks (LABs), 0.22 µm CMOS technology, and a -2 speed grade. The FineLine BGA package provides high I/O density for designs requiring many parallel interfaces in a compact footprint, suitable for legacy telecom, industrial control, and ASIC prototyping systems. Typical applications include ASIC prototyping, glue-logic consolidation, custom DSP pre-processing, telecom interface bridges, and industrial bus controllers. The device is also used in test equipment, military/aerospace (when properly screened), and legacy communications infrastructure where the FLEX-10KE architecture is well-supported by mature toolchains such as Quartus II and MAX+PLUS II. When designing with this device, ensure proper decoupling per FLEX-10KE guidelines and verify configuration mode support (e.g., passive serial, JTAG) against the toolchain version. Note that this part is now legacy hardware - confirm long-term availability with authorized distributors before committing to new designs.

EPF10K30EFC256-2XN

EPF10K30EFC256-2XN - 30K FLEX-10KE FPGA, 256-BGA, Industrial | Altera

The Intel (formerly Altera) EPF10K30EFC256-2XN is a member of the FLEX 10KE family of Field Programmable Gate Arrays (FPGAs), delivering 30,000 typical gates (17,280 usable logic elements / 1,728 logic cells) in a 256-ball FineLine BGA (FBGA) package. Built on a 0.22 micrometer CMOS SRAM process with four-layer metal interconnect, this device operates from a 2.5 V core supply (2.375 V to 2.625 V) and supports 176 user I/O pins, with internal frequency performance up to 200 MHz depending on design. The '-2X' speed grade and 'N' suffix denote an industrial temperature range (-40 C to +85 C) and lead-free / Pb-free packaging. An FPGA (Field Programmable Gate Array) is a semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnects, and dedicated I/O cells that can be re-programmed to implement arbitrary digital logic functions. FPGAs sit above fixed-function ASICs and microcontrollers in flexibility, occupying the niche between software-defined microcontrollers and fully custom silicon - enabling rapid prototyping, low-volume production, and hardware-reconfigurable signal processing. The FLEX 10KE family introduced embedded array blocks (EABs) for on-chip RAM and ROM, making it suitable for designs requiring distributed memory alongside logic. Key features include 24,576 bits of embedded RAM (6 EABs of 4,096 bits each), multi-volt I/O support (3.3 V and 5.0 V tolerant), in-system programmability via JTAG, and built-in PCI compliance for bus-interface designs. The 256-FBGA 17x17 mm package provides high pin density for compact board layouts, with all 176 user I/Os available at standard logic levels. The architecture combines 1,728 logic elements (each containing a 4-input LUT and a register) with embedded array blocks for synchronous memory, allowing single-chip implementation of glue logic, state machines, bus bridges, and DSP datapaths. MultiVolt I/O lets the device interface directly with 5 V, 3.3 V, and 2.5 V peripherals without external level shifters, a significant advantage in mixed-voltage systems. Typical applications include telecom interface cards, industrial control and automation, legacy PCI bridge logic, motor control, and glue logic replacement in telecom and embedded systems where the FLEX 10KE remains in long-lifecycle production. The industrial temperature range and EOL-managed mature-node silicon also suit it for defense and aerospace programs requiring stable, multi-decade component availability. When designing with this part, remember the FLEX 10KE requires 2.5 V core; plan a separate regulator from any 3.3 V or 5 V rails. The device is configured via JTAG or an Altera EPC configuration EEPROM, and Quartus II (legacy versions) or MAX+PLUS II software is used for design entry. For new designs, consider Cyclone IV or MAX 10 as modern, lower-power, higher-density drop-in-compatible replacements in many applications. This page synthesizes distributor pricing, drop-in alternatives, lifecycle notes, and practical design guidance for engineers maintaining FLEX 10KE-based systems, information not consolidated in the manufacturer datasheet alone.

EPF10K30EFC256-3

EPF10K30EFC256-3 - 30K FLEX 10KE FPGA, 1728 Cells, 256-BGA | Intel

The Intel (formerly Altera) EPF10K30EFC256-3 is a member of the FLEX 10KE family of SRAM-based Field Programmable Gate Arrays (FPGAs), offering 30,000 typical gates, 1,728 logic cells (LEs), and 24,576 RAM bits in a 256-ball FineLine BGA package at a -3 (faster) speed grade. Built on a 0.22 micrometer CMOS process and operating from a 2.5 V core supply, this device delivers system frequencies up to 200 MHz while exposing 176 user I/O pins for high-density glue-logic and bus-interface designs. A Field Programmable Gate Array (FPGA) is a programmable logic device (PLD) that combines gate-array-equivalent logic density with configurable interconnect, embedded memory blocks, and an I/O ring that can be programmed for multiple voltage and timing standards. FPGAs belong to the broader hierarchy: programmable logic device (PLD) -> FPGA -> SRAM-based FPGA -> look-up-table (LUT) + embedded-block architecture. The FLEX 10KE family pioneered embedded array block (EAB) integration for on-chip RAM and ROM, enabling single-chip implementation of memory-intensive functions like FIFOs and DSP datapaths. Key features of the EPF10K30EFC256-3 include 216 logic array blocks (LABs), a built-in Joint Test Action Group (JTAG) boundary-scan interface (IEEE Std 1149.1 compliant), multi-voltage I/O standards support (LVTTL, LVCMOS, PCI), and the Altera SameFrame pin-compatibility migration path that allows board reuse across the 256-pin FineLine BGA family. The -3 speed grade targets designs where the highest toggle rates and shortest combinatorial delays are required. Architecturally, the FLEX 10KE device connects each LAB through a continuous FastTrack Interconnect routing fabric, while embedded array blocks provide true dual-port RAM capability. Compared with pure gate-array ASICs, the FLEX 10KE family offers instant prototyping, in-system reconfigurability through the serial configuration device interface, and significantly lower non-recurring engineering (NRE) cost for low-to-medium-volume production. Typical applications include telecommunications line cards, industrial control and factory automation backplanes, networking routers and switches, PCI bus bridges, and legacy ASIC-replacement designs. The 256-FBGA footprint and SameFrame pin migration also enable straightforward board reuse across the FLEX 10K family density ladder. When designing with the EPF10K30EFC256-3, ensure that the configuration EPROM (EPC8 or equivalent) is correctly sized for the device bitstream and that all 2.5 V VCCINT and 3.3 V VCCIO rails are properly decoupled with bulk and high-frequency ceramic capacitors near the BGA balls. This page synthesizes distributor pricing, SameFrame drop-in alternatives within the FLEX 10K family, and practical design notes that supplement the manufacturer datasheet to accelerate component selection.

EPF10K30EFC256-3N - FLEX 10KE 30K-Gate FPGA | Intel/Altera
EPF10K30EFC256-3N

EPF10K30EFC256-3N - FLEX 10KE 30K-Gate FPGA | Intel/Altera

The Intel (formerly Altera) EPF10K30EFC256-3N is a 30,000-gate FLEX 10KE family FPGA with 1,728 logic elements, fabricated on a 0.22 um CMOS process and supplied in a 256-pin FineLine BGA (FBGA) package. It is the industry's first embedded programmable logic device family to provide System-on-a-Programmable-Chip (SOPC) integration through embedded array blocks (EABs) that implement megafunctions such as efficient memory and specialized logic functions. The device operates with a 2.5 V core supply, supports MultiVolt I/O for 2.5 V/3.3 V/5.0 V interfacing, and offers PCI-compliant 3.3 V operation at 33 or 66 MHz. An FPGA (Field-Programmable Gate Array) is a reconfigurable integrated circuit whose logic fabric is built from an array of configurable logic blocks (CLBs) connected by programmable interconnect. Embedded array blocks (EABs) augment the general-purpose LUT-based fabric with on-chip dual-port RAM and ROM, so an FPGA can absorb functions that would otherwise require a separate memory or ASIC. FPGAs sit in the broader hierarchy of programmable logic: PAL -> CPLD -> FPGA -> SoC FPGA, and they are used wherever deterministic, parallel hardware acceleration is required. Key features include 6 embedded array blocks implementing up to 24,576 RAM bits, bidirectional I/O performance up to 212 MHz, tSU and tCO propagation as fast as 0.6 ns, full PCI SIG 2.2 compliance at 33/66 MHz on -1 speed grade, open-drain output option per I/O, and JTAG boundary-scan support. MultiVolt I/O enables mixed-voltage interfacing with 2.5 V, 3.3 V, and 5.0 V devices without external translation buffers. The EPF10K30EFC256-3N architecture combines an Embedded Array for memory-intensive megafunctions with a Logic Array for general-purpose logic, and supports the same-frame pin-out migration path within the FLEX 10KE family. This allows a single PCB layout to host multiple density / package combinations, simplifying board bring-up and second-sourcing. Typical applications include PCI bus bridges, glue logic for embedded systems, communications infrastructure prototyping, industrial control interfaces, and legacy systems that require a still-supported 0.22 um CMOS FPGA. The 256-pin FBGA footprint also makes it suitable for high-density designs where leaded packages cannot meet routing requirements. A key design consideration when using this part is that the FLEX 10KE family has been classified Obsolete / End of Life by Intel, so procurement should be paired with a verified cross-reference plan. Confirm your design tools (Quartus II) and IP libraries still support the device before committing to new production runs.

The Intel (formerly Altera) EPF10K30EFC484-1 is a FLEX 10KE-series Field Programmable Gate Array (FPGA) integrating 30,000 typical gates and 1728 logic elements in a 484-ball FineLine BGA package. The device delivers up to 220 user I/Os and 24,576 bits of embedded RAM in a commercial 0C to 70C temperature grade, optimized for high-volume glue-logic and bus-interface designs. An FPGA (Field Programmable Gate Array) is a reconfigurable semiconductor device whose logic functionality is defined by a user-supplied configuration bitstream rather than at wafer fabrication. FPGAs sit between discrete TTL logic and Application-Specific Integrated Circuits in the programmable logic hierarchy, which itself belongs to the broader category of programmable logic devices (PLDs) within the integrated circuit family. The FLEX 10KE family was Altera's second-generation embedded-block SRAM FPGA, providing dedicated array blocks (EABs) for true dual-port memory, making them suitable for systems-on-a-programmable-chip (SOPC) integration. Key features of the EPF10K30EFC484-1 include 1728 logic elements, 216 logic array blocks (LABs), 24576 embedded RAM bits, 6.0 ns typical pin-to-pin propagation delay, and 80 MHz internal performance. The device supports MultiVolt I/O (operating with mixed 2.5V/3.3V/5.0V signaling rails through independent VCCIO banks), PCI-compliant I/O with on-chip clamping diodes, slew-rate control, and open-drain output options configurable on a per-pin basis. JTAG boundary-scan test (IEEE 1149.1) is provided for board-level test access. The FLEX 10KE architecture combines a fine-grained logic element fabric with coarse-grained Embedded Array Blocks (EABs), allowing efficient implementation of wide functions, multipliers, and small FIFOs without consuming general-purpose logic. The 5x5 mm FineLine BGA package supports SameFrame pin migration to other 10KE densities in the 484-pin BGA family, simplifying design portability across the series. Typical applications include telecommunications interface cards, industrial glue logic and bus bridges, PCI bus interface glue, test and measurement backplanes, and legacy system upgrades. The 484-ball BGA footprint supports dense PCB layouts while preserving a moderate pincount. When designing with this part, verify the Altera Quartus MAX+PLUS II design toolchain compatibility and the legacy PCN status before committing to new designs. Several Altera MAX+PLUS II and Quartus versions do not support FLEX 10KE in current releases.
