EPF6016TC144-3N - FLEX 6000 FPGA 16K Gates 117 IOs | Intel
The Intel EPF6016TC144-3N is a member of the FLEX 6000 family of SRAM-based Field Programmable Gate Arrays (FPGAs), housed in a 144-pin TQFP (TQ144) surface-mount package and providing approximately 16,000 usable gates with 117 user I/Os. It contains 132 Logic Array Blocks (LABs), an internal frequency of 172 MHz, and operates over the commercial 0°C to 85°C temperature range. The "3N" speed grade and "TC144" package designators indicate a -3 speed bin in a TQFP-144 commercial-temperature grade. A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs) connected by programmable interconnect, allowing hardware designers to implement arbitrary digital logic that can be re-programmed in the field. FPGAs sit within the programmable logic hierarchy between simple SPLDs/CPLDs and full-custom ASICs, and the FLEX 6000 family uses SRAM configuration cells, so the design is loaded from an external configuration memory on every power-up. The EPF6016TC144-3N is a low-density, low-cost member of this family aimed at glue-logic, bus-interface, and small state-machine designs. Key features of the EPF6016TC144-3N include 117 user I/O pins distributed across the 144-pin TQFP footprint, 132 LABs providing the basic logic granularity of the FLEX 6000 architecture, and a 172 MHz internal operating frequency that supports common 33/66/100 MHz bus interfaces. The device supports multiple I/O standards and is configured via the Altera (now Intel) Quartus / MAX+PLUS II development flow, with EDIF 2.0/3.0, VHDL, Verilog HDL, and AHDL interfaces accepted at design entry. The FLEX 6000 architecture is built on a CMOS SRAM process with a 5V-tolerant I/O ring (typical for this family) and a lookup-table (LUT)-based LAB that contains eight logic elements. Because the configuration is volatile, a serial or parallel configuration PROM (such as an EPC2 or EPC16) must be present on the board to load the bitstream at power-up. The EPF6016TC144-3N's 132 LABs give roughly the same logic capacity as 2,000-3,000 typical gates of usable logic, depending on synthesis efficiency. Typical applications for the EPF6016TC144-3N include bus-bridging glue logic between microprocessors and peripherals, small DSP or state-machine controllers, legacy parallel-port emulation, prototype ASIC replacement, and industrial-control interface logic. The FLEX 6000 family was designed as a low-cost alternative to gate-array ASICs for high-volume applications where design changes are still expected during prototyping. When designing with this device, plan for an external configuration memory because the FLEX 6000 SRAM cells lose their pattern at power-down. The 144-pin TQFP package has generous board-area requirements compared to modern BGA FPGAs, so reserve roughly 22 × 22 mm of PCB area. Quartus support for FLEX 6000 is legacy, so verify that the latest Quartus version still supports this older device family before committing to it for new designs. This page consolidates distributor stock and pricing, drop-in TQFP-144 alternatives from the FLEX 6000 family, and practical design notes that go beyond the manufacturer datasheet.

The Altera (Intel) EPF6016TC144-3U is a member of the FLEX 6000 family of CMOS SRAM-based Field Programmable Gate Arrays (FPGAs), integrating 16,000 typical gates (24,000 maximum), 1,320 logic cells (LEs), and 117 user I/Os in a 144-pin TQFP (TC144) package with industrial-grade timing. It is built on a 0.42 µm CMOS SRAM process and offers 4 ns pin-to-pin logic delays in the speed grade -3 variant. An FPGA (Field Programmable Gate Array) is a programmable logic device that allows designers to implement custom digital logic circuits after manufacturing. The FLEX 6000 architecture belongs to the broader taxonomy of programmable logic devices (PLDs), which also includes CPLDs (Complex Programmable Logic Devices) and SPLDs (Simple Programmable Logic Devices). FPGAs are distinguished from CPLDs by their SRAM-based configuration memory, finer-grained logic elements, and higher gate count, making them suitable for glue logic, bus interfacing, and moderate-complexity state machines. The device contains 1,320 Logic Elements (LEs) organized into Logic Array Blocks (LABs), 16 embedded Logic Array Blocks, and embedded memory structures that enable efficient implementation of FIFOs, shift registers, and small state machines. Configuration is loaded from an industry-standard EPC1/EPC2 configuration PROM or via JTAG (IEEE 1149.1 Boundary-Scan). Each I/O pin supports 3.3 V LVTTL and 5.0 V PCI interfaces, with slew-rate control and tri-state buffering. Typical applications include glue logic replacement, bus interfacing (PCI, ISA), DSP co-processing front-ends, industrial control logic, and telecommunications line cards. The 117 available I/Os make it suitable for parallel bus bridges, memory controllers, and legacy peripheral aggregation in embedded systems. The TQFP-144 package is a fine-pitch surface-mount format (0.5 mm pitch) that supports prototype and small-to-medium volume production. When designing with this part, observe the I/O bank supply voltage constraints (VCCIO must match driven logic levels), and verify JTAG chain configuration before relying on boundary-scan testing. Configuration data is volatile: the device must be re-configured at every power-up. Use the Altera MAX+PLUS II or Quartus design tools with FLEX 6000 device support to generate programming files. The 'U' suffix indicates an industrial temperature grade and tray packaging.
EPF6016TC1443N - FLEX 6000 FPGA, 16K Gates, 117 I/O, 144-LQFP | Intel
The Intel EPF6016TC1443N is a FLEX 6000 family Field Programmable Gate Array (FPGA) delivering 16,000 gates and 1,320 logic elements/cells in a 144-pin LQFP package. The device provides 117 user I/Os organized across the package perimeter and operates from a 5V core supply with 3.3V/5V multi-voltage I/O support. The '-3' speed grade targets moderate-performance logic applications where cost-effective SRAM-based programmability is required. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the designer can reprogram after manufacture to implement arbitrary digital logic. Within the broader programmable logic hierarchy, FPGAs sit above simple PLDs and below structured ASICs in cost-per-volume, offering rapid prototyping, field upgrades, and lower NRE than mask-programmed devices. The FLEX 6000 family is Intel's (formerly Altera's) classic SRAM-based FPGA line intended for glue logic, bus bridging, and state-machine applications. Key features of the EPF6016TC1443N include 1,320 logic elements distributed across 132 Logic Array Blocks (LABs), embedded SRAM for distributed register and FIFO functions, and 117 I/O pins supporting PCI-compliant signaling and multi-voltage I/O standards. The device supports in-system programmability through its 5V-friendly configuration interface and is supported by the legacy MAX+PLUS II and Quartus design toolchains. The FLEX 6000 architecture combines a fine-grained logic element with a continuous routing network, providing predictable timing and high utilization. The 0.5 µm process technology and SRAM configuration cells allow unlimited reconfiguration, though an external configuration PROM (EPC) is required at power-up to load the bitstream into the FPGA's SRAM array. Typical applications include PCI bus interface bridges, glue logic between microprocessors and peripherals, custom state-machine controllers, industrial control and instrumentation front-ends, and legacy telecommunication backplane glue. The wide 117-I/O count and 5V-tolerant I/Os make it well suited for mixed-voltage systems that need to bridge 5V peripherals to 3.3V cores. When designing with this device, ensure the configuration PROM (EPC1, EPC2, or EPC16) is correctly sized for the bitstream and that JTAG programming access is provided for in-field updates. The 144-LQFP package requires careful PCB layout to maintain signal integrity on the high-pin-count parallel interfaces. This page synthesizes distributor pricing, drop-in alternatives drawn from the FLEX 6000 family, and practical design notes not collected in a single place in the legacy Altera datasheet, giving engineers a single reference for selection, sourcing, and PCB reuse.
EPF6016TI144-2 - 16K FLEX 6000 FPGA, 117 I/O, 144-LQFP | Altera
The Altera EPF6016TI144-2 is a member of the FLEX 6000 family of Field-Programmable Gate Arrays (FPGAs) delivering 16,000 typical gates, 1,320 logic elements, and 117 user I/Os in a 144-pin LQFP (TQFP) package. Built on a 0.42 micron SRAM-based process, this loadable PLD integrates 132 Logic Array Blocks (LABs) operating from a 5V supply, with an internal frequency rated up to 172 MHz. Per the manufacturer datasheet, the device targets high-volume gate-array replacement designs where fast design changes are required during prototyping or production ramp. An FPGA (Field-Programmable Gate Array) is a programmable logic device containing an array of configurable logic blocks (CLBs), routing interconnects, and I/O cells that the designer configures via a hardware description language and a vendor-supplied bitstream. FPGAs sit above CPLDs (Complex Programmable Logic Devices) in the programmable logic hierarchy because they offer higher logic density, distributed RAM, and dedicated routing - and below ASICs because they are reprogrammable rather than mask-programmed. The FLEX 6000 family, launched by Altera in the late 1990s, occupies the low-density end of the FLEX hierarchy between the MAX 7000 CPLD family and the FLEX 10K family. Key features of the EPF6016TI144-2 include in-system programmability through the IEEE 1149.1 (JTAG) interface, an SRAM-based configuration cell that supports unlimited reconfiguration cycles, multiVolt I/O supporting 5V/3.3V/2.5V interfacing, and per-pin tri-state control. The device is supported by the Quartus design tool chain (legacy Max+Plus II for original bitstream generation). It is designed for 5V core operation, which differentiates it from the lower-voltage FLEX 10K family. Architecturally, the FLEX 6000 device consists of Logic Array Blocks arranged in rows and columns, each LAB containing 10 Logic Elements (LEs) with a four-input look-up table (LUT) and a dedicated register. The embedded FastTrack continuous routing structure provides predictable timing with horizontal and vertical routing segments connecting every LAB, and the I/O elements (IOEs) are placed at the periphery of the die for 117 user I/Os at this package option. Typical applications include glue logic replacement in telecom infrastructure, industrial control and factory automation interfaces, low-density bus interface bridges, and legacy system retrofits where 5V-tolerant I/O is required. Designers transitioning from older discrete TTL/CMOS gate arrays often choose this part because the LQFP-144 footprint enables hand-reworkable prototyping on standard 0.5mm-pitch PCB technology. When designing with this part, ensure your configuration bitstream storage and JTAG chain comply with the FLEX 6000 configuration handbook. The 5V core voltage means decoupling requirements differ from modern sub-3V FPGAs; a minimum 100uF bulk plus 0.1uF high-frequency decoupling per power pin is recommended per the application notes. This page synthesizes distributor pricing, drop-in FLEX 6000 same-package variants, and design notes not assembled on the original Altera datasheet - useful for engineers managing legacy designs or sourcing drop-in replacements for EOL inventory.
EPF6016TI144-3 - FLEX 6000 FPGA, 1320 Cells, 117 I/O | Intel
The Intel (formerly Altera) EPF6016TI144-3 is a member of the FLEX 6000 family of Field Programmable Gate Arrays (FPGAs) with 1320 logic cells, 117 user I/Os, and a 125 MHz internal frequency, housed in a 144-pin LQFP (TQFP) package. Built on a 0.42 µm CMOS SRAM process, this device operates from a 5 V VCCINT core supply with VCCIO banks supporting 3.3 V or 5 V I/O standards for mixed-voltage system integration. An FPGA (Field Programmable Gate Array) is a semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be reconfigured by the end user after manufacture. FPGAs sit hierarchically under programmable logic devices (PLDs) within the broader digital IC family and are used to implement custom digital circuits without the cost or lead time of an ASIC. The FLEX 6000 series specifically targets low-cost, high-volume glue logic and gate-array replacement applications with SRAM-based configuration. Key features of the EPF6016TI144-3 include 16,000 typical gates, 1,320 logic elements, fast continuous interconnect, JTAG-based in-system programmability via the ByteBlaster or BitBlaster port, and a JTAG boundary-scan test interface compliant with IEEE Std 1149.1. The -3 speed grade designation places this part in the faster commercial tier of the FLEX 6000 family. With 117 user I/Os and a 144-pin TQFP footprint, the device provides ample connectivity for medium-complexity control, bridging, and bus-interface designs. The EPF6016TI144-3 uses a 4-input look-up table (LUT)-based logic element, fast row and column interconnect channels, and embedded memory cells distributed throughout the array. The SRAM configuration memory allows unlimited re-programmability in-system, and the FLEX 6000 architecture supports hot-socketing for field upgrades. The Quartus II and legacy MAX+PLUS II design software provide VHDL, Verilog HDL, and EDIF 2 0 0 / 3 0 0 interfaces with full timing simulation and synthesis flows. Typical applications include telecommunications line-card glue logic, industrial control and instrumentation, peripheral bus interfacing (PCI bridge, microcontroller expansion), and prototyping for gate-array or ASIC designs. The 5 V core and 3.3 V tolerant I/O make it well suited for legacy 5 V systems and 3.3 V mixed-voltage designs. When designing with this device, pay close attention to the VCCINT/VCCIO separation: VCCIO must be at least 4.75 V for tOD1 timing, otherwise tOD2 (nominally slower) applies. Decoupling must follow the reference design's capacitor count and placement to maintain signal integrity on the 117 I/O pins.

EPF6016TI144-3N - FLEX 6000 FPGA, 16K Gates, 144-LQFP | Intel / Altera
The Intel (formerly Altera) EPF6016TI144-3N is a member of the FLEX 6000 family of Field Programmable Gate Arrays (FPGAs), delivering approximately 16,000 logic gates (1,320 logic elements / 132 LABs) at a 0.42 µm CMOS process node, packaged in a 144-pin LQFP (TQFP) with gull-wing leads. The device supports up to 117 user I/O pins and operates on a 5.0 V core supply with selectable VCCIO rails of 3.3 V or 5.0 V for flexible mixed-voltage interfacing. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs / LEs), programmable interconnect, and programmable I/O cells. The FLEX 6000 family sits within the hierarchy PLD -> CPLD/FPGA -> programmable logic -> semiconductor, and was Altera's low-cost SRAM-based FPGA line targeting glue-logic, bus-interface, and high-volume gate-array replacement applications. FPGAs differ from CPLDs in that they offer higher logic density, finer-grained architecture, and SRAM-based configuration that can be reloaded in-system. Key specifications of the EPF6016TI144-3N include 16,000 usable gates, 1,320 logic cells organized into 132 Logic Array Blocks (LABs), 117 user I/O, and an internal operating frequency of up to 125 MHz. The '-3N' speed-grade suffix indicates a faster timing bin than the '-2' / '-4' grades, while 'N' denotes an industrial temperature rating (0 °C to +85 °C). The device is configured via a serial EPROM or in-system via JTAG, with built-in support for MultiVolt I/O enabling 5.0 V tolerance on a 3.3 V VCCIO rail. The FLEX 6000 architecture uses a four-input look-up table (LUT) per logic element, fast-track interconnect for predictable routing delays, and dedicated carry chains for arithmetic. Configuration RAM is SRAM-based, so the device requires a configuration EPROM (EPC1, EPC2, or compatible) at every reset, or a micro-based controller for in-system programming. Typical applications include glue logic in telecom line cards, industrial control boards, PCI / ISA bus bridges, custom peripheral controllers, and prototype gate-array emulation. The wide VCCIO range also makes the part suitable for mixed 3.3 V / 5.0 V legacy systems that require voltage translation on the same board. When designing with the EPF6016TI144-3N, plan for a configuration EPROM on every board since the SRAM-based fabric loses its bitstream at power-down. Reserve four dedicated JTAG pins (TCK, TMS, TDI, TDO plus TRST) for boundary-scan and in-system programming, and ensure the 5.0 V core supply is well decoupled near the device. The LQFP-144 footprint is hand-solderable and rework-friendly but the -3 speed grade dissipates more dynamic current than -4 (slower) grades. This page synthesizes distributor stock levels, parametric drop-in alternatives from the same FLEX 6000 family, and practical design notes for designers evaluating the EPF6016TI144-3N against modern FPGA replacements.
EPF6016TI1442 - FLEX 6000 FPGA, 16K Gates, 144-TQFP | Altera
The Altera (Intel) EPF6016TI1442 is a member of the FLEX 6000 family of SRAM-based field-programmable gate arrays (FPGAs) offering 16,000 typical gates and 1,320 logic elements in a 144-pin Thin Quad Flat Pack (TQFP) package with industrial-grade temperature rating. It features 117 user I/O pins, an operating voltage of 5.0 V, and speed grade 2 timing, providing a balance of logic density and I/O bandwidth for cost-sensitive embedded designs. An FPGA (Field Programmable Gate Array) is a reconfigurable integrated circuit containing an array of configurable logic blocks (CLBs), programmable routing channels, and I/O cells, all of which can be redefined after manufacturing. FPGAs occupy a tier in the digital IC hierarchy above CPLDs and below ASICs, offering higher logic density than CPLDs but more flexibility and lower NRE cost than ASICs. The FLEX 6000 family was one of Altera's first OptiFLEX architecture generations, optimizing logic-cell utilization and interconnect delay for glue-logic, bus-interface, and state-machine applications. Key features of the EPF6016TI1442 include 4,992 typical logic elements (LEs), 6 embedded array blocks (EABs) for distributed RAM or ROM, 117 user I/O pins supporting PCI compliance, and JTAG-based IEEE 1149.1 boundary-scan testing. The device operates on a 5.0 V core supply with 3.3 V or 5 V tolerant I/O banks, and is offered in speed grade -2 (mid-tier performance). Its industrial-grade temperature range (-40°C to +85°C) supports factory, automotive cabin, and outdoor equipment environments. The EPF6016TI1442 utilizes an SRAM configuration cell that requires an external configuration memory (typically an EPC configuration device such as EPC2, EPC4, or EPC8) or JTAG download to load the bitstream at every power-up. This volatile configuration architecture allows unlimited in-system re-programmability, which is useful for prototype iteration and field upgrades. Typical applications include industrial control logic, glue logic for ASIC/microprocessor systems, bus interface bridging (PCI, ISA, VME), DSP co-processing front-ends, and prototyping platforms for ASIC emulation. The 117 user I/O pins also support datapath-heavy interfaces such as 32-bit microcontrollers, video pixel processing, and telecommunication line cards. When designing with this part, ensure the configuration memory (EPC device) is correctly sized for the bitstream, and that JTAG chain integrity is verified before first power-up. Because the SRAM cells are volatile, any power interruption erases the design - a non-volatile configuration source is mandatory. The FLEX 6000 family has been superseded by newer families (Cyclone, MAX), so lifecycle planning is critical for long-life products. This page synthesizes distributor stock signals, same-package drop-in alternatives from the FLEX 6000 family, and practical design notes not found in the original Altera datasheet to support procurement and engineering decisions.

FPGAs sit within the broader category of programmable logic devices (PLDs), alongside CPLDs and anti-fuse devices, and are used wherever high gate counts, fast time-to-market, or field-upgradable logic are required. Key features include a 5.0V core voltage, 3.3V I/O compatibility option, in-system programmability via JTAG, and support for PCI, PCI-X, and other standard I/O interfaces. The 256-BBGA package provides a compact footprint and supports high-density board designs. The 218 I/O count, combined with 1,960 logic cells, allows designers to integrate multiple glue-logic functions, state machines, and bus controllers into a single device. Architecturally, the EPF6024A employs a SRAM-based configuration memory, fast-row interconnect (OptiFLEX), and dedicated carry chains for arithmetic. The LUT-based logic cells (LEs) deliver predictable timing through fast deterministic interconnect paths. Configuration is loaded from a serial EPROM, JTAG, or microcontroller on power-up, allowing design changes to be made at any time. Typical applications include telecommunications line cards, industrial control boards, prototype gate-array replacement, PCI/PCI-X bus bridges, and embedded control logic. The part's 5.0V tolerance also makes it attractive for legacy designs migrating from discrete TTL. When designing with this part, note that the FLEX 6000 family is no longer recommended for new designs - the device is in NRND/EOL status with limited inventory. Designers should evaluate Altera/Intel MAX series or Cyclone family for new designs and use EPF6024ABC256-1 only when matching existing hardware. This page synthesizes distributor inventory, same-family FLEX 6000 drop-in alternatives, lifecycle observations, and practical design considerations not consolidated on the manufacturer datasheet.

The "-3" suffix denotes the speed grade, with "A" indicating the 256-BBGA package and "BC" denoting the BGA variant and commercial temperature grade. What is an FPGA? An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that allows designers to configure digital logic blocks and interconnects after manufacturing. FPGAs sit in the hierarchy: PLD -> FPGA -> SRAM-based FPGA -> FLEX 6000 family -> low-cost programmable logic, offering an alternative to gate arrays and ASICs for medium-volume designs. The FLEX 6000 series was Altera's first SRAM-based family targeting low-cost, high-volume applications previously served by masked gate arrays. Key features include 196 Logic Array Blocks (LABs) with Embedded System Blocks (ESBs) for memory, 4 phases of delay-locked loop (DLL) for clock skew management, multiVolt I/O supporting 3.3 V and 5.0 V mixed-voltage systems, and in-system programmability via the IEEE 1149.1 (JTAG) boundary-scan interface.

Architecturally, the EPF6024ABC256-3 uses a continuous SRAM configuration cell powered by a 0.42 µm four-layer-metal CMOS process. Each LAB contains 10 Logic Elements (LEs), each LE implementing a 4-input look-up table (LUT), a programmable flip-flop, and dedicated carry and cascade chains. This LUT-based fabric provides fast, predictable combinational and sequential logic with deterministic timing. Typical applications include glue logic, bus interfaces, peripheral controllers, telecommunications glue, industrial control, and prototyping of gate-array designs. It was widely adopted as a low-cost programmable alternative to high-volume gate-array applications and allows fast design changes during prototyping or design testing. When designing with this device, ensure adequate decoupling on all VCCINT and VCCIO pins and follow the IBIS models for signal-integrity simulations. Designers should also note that the FLEX 6000 family has reached end-of-life and is no longer recommended for new designs — consider Cyclone or MAX series for new projects.

EPF6024ABI256-2 - FLEX 6000 FPGA 24K Gates 256-BGA | Altera
The Altera (now Intel) EPF6024ABI256-2 is a FLEX 6000 family Field Programmable Gate Array (FPGA) with 24,000 gates, 1,960 logic cells, and 218 user I/O, packaged in a 256-ball BGA (27x27 mm) operating at 3.3V core. The device is fabricated on a 0.42 um CMOS process and is targeted at high-volume, low-cost programmable-logic designs that need fast design iteration. What is an FPGA? An FPGA (Field Programmable Gate Array) is a semiconductor IC composed of configurable logic blocks (LBs), programmable interconnect, and programmable I/O cells. FPGAs sit between fixed-function ASICs (high NRE, low unit cost at volume) and CPLDs (smaller, non-volatile) in the programmable-logic hierarchy. Within that hierarchy, the FLEX 6000 family is Altera's register-rich, look-up-table (LUT) based, SRAM-volatile low-cost family: each logic element combines a 4-input LUT with a register, and configuration data is loaded from an external EPROM or microcontroller at every power-up. Key features include a register-rich LUT-based architecture with 1,960 logic elements arranged in 196 LABs, integrated OptiFLEX interconnect, multiVolt I/O supporting 5.0V, 3.3V and 2.5V interfaces, and in-system programmability through the IEEE 1149.1 (JTAG) boundary-scan interface. The part is offered in a -2 speed grade with a typical internal operating frequency of 166.67 MHz. Typical applications include glue-logic replacement, interface bridging (5V-to-3.3V level translation, parallel-to-serial conversion), industrial control boards, telecom line cards, and prototyping platforms where design changes must be made quickly without respinning a mask set. When designing with the EPF6024ABI256-2, allocate one dedicated configuration device (EPC2 or compatible) on the board because the SRAM cells lose configuration on power-down. Place 0.1 uF decoupling capacitors within 5 mm of every VCC/VCCIO pin, and follow Altera's AN 74 guidelines for multiVolt I/O bank placement to avoid contention between 5V and 3.3V peripherals.

The Intel (Altera) EPF6024AFC256-1 is a member of the FLEX 6000 family of Field Programmable Gate Arrays (FPGAs), delivering 24,000 gates, 1,960 logic cells, and a maximum internal frequency of 200 MHz. It is housed in a 256-pin FineLine Ball Grid Array (FBGA) package and operates from a 3.3V supply, making it a low-cost programmable alternative to high-volume gate-array ASICs. The device targets glue-logic, bus-interface, and high-volume consumer applications where fast design changes during prototyping are required. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines configurable logic blocks (LABs), programmable interconnects, and I/O cells on a single semiconductor die. FPGAs sit within the programmable logic hierarchy: PLD -> CPLD -> FPGA -> SoC FPGA, and form part of the broader semiconductor landscape of digital ICs used for parallel logic implementation, DSP, and hardware acceleration. The FLEX 6000 series specifically targets cost-sensitive, register-intensive designs with SRAM-based configuration. Key features of the EPF6024AFC256-1 include 196 logic array blocks (LABs), 218 user I/O pins, and 0.42 µm CMOS process technology. The SRAM-based configuration memory supports in-system programmability via a serial configuration device, allowing rapid design iteration. Per the Altera FLEX 6000 datasheet family, the device supports both 3.3V PCI compliance and 5.0V tolerance on I/O banks, with multiVolt I/O enabling interface to 2.5V, 3.3V, and 5.0V devices. Typical applications include telecommunications line cards, industrial control glue logic, bus-interface bridging (PCI, ISA, VME), consumer set-top box control planes, and high-volume production replacements for legacy ASICs. The 218 I/O count makes it suitable for parallel interface aggregation, while the 256-BGA package keeps board footprint compact for high-density designs. When designing with the EPF6024AFC256-1, observe maximum I/O toggle rate and ground-bounce limits from the datasheet. Because the part is SRAM-based, an external configuration ROM (such as an EPC1 or EPC2) is required at power-up to load the bitstream. Decoupling must follow the datasheet's recommended capacitor network (typically 0.1 µF + 10 µF per VCC/GND pair). This page synthesizes distributor stock, lifecycle notes, and drop-in alternatives from the Altera FLEX 6000 family that are not collated on the manufacturer datasheet itself, helping sourcing engineers and procurement teams quickly evaluate replacement paths for legacy Altera FPGA designs.

The device also supports 5-V tolerant I/O operation when configured for mixed-voltage system integration. The FLEX 6000 architecture uses a continuous, uninterrupted routing fabric with no segmented long-line penalties, simplifying timing closure at frequencies up to 166.67 MHz. SRAM configuration cells allow unlimited re-programming cycles, which is essential for design iteration and field upgrades. The 0.42 micrometer process keeps per-unit cost low while delivering adequate performance for glue logic, bus bridging, and peripheral interfacing. Typical applications include communications glue logic, industrial control interfaces, legacy peripheral bridging (PCI to ISA bridges), printer and image-processing controllers, and low-cost ASIC prototyping. The high I/O count makes the EPF6024AFC256-2AA particularly well suited to designs that aggregate many slow-speed signals. When designing with this device, plan for a dedicated configuration EEPROM (such as the EPC2) and verify that your synthesis tool flow is still maintained; FLEX 6000 devices predate the Quartus Prime flow and are typically used with the legacy MAX+PLUS II or early Quartus toolchains. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
EPF6024AFC256-3 - 24K Gates 1960 Cells FLEX 6000 FPGA | Intel | BGA-256
The Intel (formerly Altera) EPF6024AFC256-3 is a 24K-gate FLEX 6000 family Field Programmable Gate Array (FPGA) with 1960 logic cells, 218 user I/Os, and a maximum internal frequency of 172 MHz, fabricated on a 0.42 umm CMOS process and supplied at 3.3 V in a 256-pin FineLine BGA package. The -3 speed grade designates the faster of three commercial grades offered in the FLEX 6000 family, making this part suited to glue logic, control plane, and low-density signal processing applications where ASIC-equivalent performance is not required. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the density of gate arrays with the design flexibility of in-system programmability. Within the broader semiconductor taxonomy, FPGAs sit alongside CPLDs (Complex Programmable Logic Devices), SPLDs (Simple PLDs), and ASICs as configurable digital logic. FPGAs are typically used when design iteration speed, low NRE cost, or post-deployment field updates outweigh the per-unit cost advantage of a masked ASIC. The FLEX 6000 family from Altera (now Intel PSG) was an early SRAM-lookup-table-based family that bridged the gap between low-density CPLDs and high-density FLEX 10K devices. Key features of the EPF6024AFC256-3 include 1960 logic elements arranged in Logic Array Blocks (LABs), 218 maximum user I/O pins, on-chip SRAM for lookup-table-based logic implementation, an internal frequency spec of 172 MHz, a 0.42 umm process node, and 3.3 V core/IO supply. The 256-ball FineLine BGA (FBGA) package supports high I/O count with controlled-impedance signal paths suitable for backplane and multi-board designs. The FLEX 6000 family is configured via the Altera MAX+PLUS II / Quartus development flow over a serial or parallel configuration interface. Typical applications include industrial control glue logic, low-density bus bridges, peripheral expansion interfaces for embedded processors, prototyping platforms for ASIC migration, and legacy system refresh designs where the original CPLD/ASIC has been discontinued. The 3.3 V supply voltage is directly compatible with 3.3 V PCI, 3.3 V microprocessors, and LVCMOS I/O standards of its era. The 218 user I/O count supports bus-oriented designs such as 16-bit data buses plus address, control, and clock signals. When designing with this device, ensure your Quartus/MAX+PLUS II toolchain version still supports the FLEX 6000 family; newer Quartus releases have removed legacy device support. The -3 speed grade delivers the highest fMAX of the family and should be selected when timing closure is more important than power. Supply decoupling requires multiple bulk and high-frequency ceramic capacitors near each supply ball due to the simultaneous-switching-output (SSO) behavior of high-pin-count BGA packages.

The 'I' suffix in the package code indicates an industrial temperature grade, supporting -40°C to +85°C ambient operation. The device is supported by the Altera Quartus design toolchain (legacy MAX+PLUS II is also compatible for older designs), enabling schematic, VHDL, and Verilog entry. MultiVolt I/O compatibility allows interfacing with 3.3V and 5.0V peripherals on the same die. The OptiFLEX architecture combines a continuous routing matrix with fine-grained logic cells, providing high utilization and predictable timing closure for control-logic and datapath designs. Embedded memory and dedicated clock networks are not available in the FLEX 6000 family; designers needing these features migrate to FLEX 10K or Cyclone families. The 256-pin FBGA package supports board-level manufacturing with standard surface-mount processes and reflow soldering. Typical applications for the EPF6024AFI256-2 include industrial control logic, communication protocol bridging, glue logic between microcontrollers and peripherals, custom state machines for instrumentation, and legacy design maintenance in telecom and test equipment. Designers commonly pair it with EPROM-based configuration memory to store the SRAM configuration bitstream. When designing with this device, ensure that the configuration memory and clock distribution support the target frequency and that the I/O bank voltages match the connected peripherals. For modern designs, engineers should evaluate migration to FLEX 10K, MAX II, or Cyclone families for higher density and lower power. The device is mature and may be sourced primarily through authorized distributors and franchised brokers as new production is limited.

EPF6024AQC-280 - FLEX 6000 FPGA, 24K Gates, QFP-280 | Altera
The Altera (now Intel) EPF6024AQC-280 is a member of the FLEX 6000 family of programmable logic devices, delivering approximately 24,000 typical gates in a 280-pin QFP package. The 'AQC' suffix denotes an enhanced -A speed grade with the -280 designating the QFP-280 pin count, and the device is fabricated on a 5 V SRAM-based CMOS process with in-system programmability via the Altera MAX+plus II / Quartus flow. A programmable logic device (PLD) such as the FLEX 6000 FPGA is a digital integrated circuit whose logic function is defined by user-supplied configuration data rather than hard-wired masks. It sits in the broader taxonomy of digital ICs: PLD -> programmable logic -> FPGA (Field-Programmable Gate Array) -> semiconductor device. FPGAs occupy the highest flexibility tier of this hierarchy, allowing hardware-level parallelism with reconfiguration that microcontrollers and DSPs cannot match for true hardware-acceleration tasks. The EPF6024AQC-280 integrates up to 1,960 logic elements (LEs), 24,960 RAM bits of embedded memory, and dedicated I/O elements distributed across user I/O banks supporting multiple I/O standards including 5 V, 3.3 V, and 2.5 V. Its architecture uses Look-Up Table (LUT)-based logic with fast continuous-routing interconnects, and supports JTAG-based IEEE 1149.1 boundary-scan test. The device includes built-in circuitry for global clock networks, phase-locked loops (in the -A speed grade family), and hot-socketing support. Typical applications for the EPF6024AQC-280 span glue-logic consolidation in telecom line cards, industrial control and factory-automation backplanes, and PCI-bus interface bridging where the device replaces dozens of discrete 74-series logic chips. The high 280-pin count and ample I/O count also suit it for prototyping ASIC front-ends and for educational/legacy designs that predate the migration to Cyclone-series devices. When designing with the EPF6024AQC-280, engineers should note that the FLEX 6000 family predates Cyclone, MAX II and MAX V parts; new designs should evaluate Cyclone II/III or MAX V/VII for lower power and modern packaging, while reserving FLEX 6000 for legacy system maintenance and form-fit replacements. Decoupling, multi-voltage I/O bank planning, and JTAG chain design remain the critical PCB-level concerns. This page synthesizes Altera FLEX 6000 datasheet extracts, distributor pricing snapshots, same-package drop-in alternatives from the EPF6024 family, and practical design notes that are not duplicated on the manufacturer datasheet itself. Information gain includes pinout, same-package footprint confirmation across -3 speed grade variants, and JTAG programming recommendations tailored to legacy MAX+plus II toolchains.

The Intel (formerly Altera) EPF6024AQC208-1 is a member of the FLEX 6000 family of SRAM-based Field-Programmable Gate Arrays (FPGAs) offering 24,000 typical gates, 1,960 logic elements (LEs), and 196 Logic Array Blocks (LABs) in a 208-pin Power Quad Flat Pack (PQFP/BFQFP) package. Fabricated on a 0.42 µm CMOS process and operating from a 3.3 V supply, the device supports up to 171 user I/O pins and is specified for commercial 0 °C to 85 °C operating temperature with the -1 speed grade targeting internal frequencies up to approximately 200 MHz. A field-programmable gate array (FPGA) is a semiconductor integrated circuit that can be reconfigured by the customer after manufacture to implement arbitrary digital logic. FPGAs sit in the programmable-logic hierarchy between simple SPLDs/CPLDs and high-end structured ASICs, combining configurable logic blocks (LEs), programmable routing, and dedicated I/O cells. The FLEX 6000 family in particular pioneered low-cost, high-volume gate-array replacement for glue logic, prototyping, and design-iteration workflows in the late 1990s and early 2000s. Key features of the EPF6024AQC208-1 include 1,960 logic elements organised into 196 LABs, an internal frequency up to 200 MHz for the -1 speed grade, 171 user I/Os, and JTAG-based in-system programmability through the Altera/Quartus tool chain. Each LE contains a 4-input look-up table, a programmable register, and dedicated carry and cascade chains for arithmetic and wide fan-in functions, while each LAB groups 16 LEs with local interconnect for high-speed logic-cluster operation. The device is built on a 0.42 µm five-layer-metal CMOS process and uses SRAM configuration cells, allowing unlimited reconfigurations in-system. Configuration is typically loaded from a serial or parallel EPROM via the dedicated configuration interface. Built-in JTAG (IEEE 1149.1) boundary-scan test supports board-level interconnect verification without bed-of-nails fixtures, while the I/O cells support a range of 3.3 V LVTTL/LVCMOS standards with programmable drive strength and slew-rate control. Typical applications include communication equipment glue logic, industrial control and instrumentation interfaces, legacy ASIC prototyping, high-volume gate-array replacement designs, and embedded control subsystems. The 171 available I/Os in a 208-pin PQFP also make it suitable for bridging multiple buses (e.g. microprocessor, memory and peripheral buses) inside dense backplane designs. When designing with this device, ensure the Quartus/MAX+PLUS II fitter is configured for the EPF6024AQC208-1 device family and -1 speed grade, and that configuration storage (EPC1/EPC2 or compatible PROM) is sized for the 1,960-LE bitstream. The PQFP package requires a generous PCB pad/land pattern and careful thermal relief for production reflow. This page synthesises distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a faster path to validation, replacement, and sourcing decisions for the EPF6024AQC208-1.
EPF6024AQC208-1N - FLEX 6000 FPGA 24K Gates 208-PQFP | Intel
The Intel (formerly Altera) EPF6024AQC208-1N is a member of the FLEX 6000 family of SRAM-based Field-Programmable Gate Arrays (FPGAs) delivering 24,000 typical gates and 1,960 logic elements (cells) in a 208-pin Plastic Quad Flat Pack (PQFP / 208-BFQFP) package. The device operates from a 3.3 V supply and is fabricated on a 0.42 µm CMOS process, supporting up to 171 user I/Os and 196 Logic Array Blocks (LABs) with internal frequencies up to 200 MHz. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing — hence "field-programmable". FPGAs sit at the top of the programmable logic hierarchy: programmable logic devices (PLDs) -> complex PLDs (CPLDs) -> FPGAs -> SoC FPGAs. The FLEX 6000 family in particular was an early 1990s low-cost, high-volume SRAM-LUT architecture targeting glue logic, bus interface, and state-machine replacement, allowing fast design changes during prototyping without the NRE of an ASIC. Key features of the EPF6024AQC208-1N include 196 LABs arranged across the chip fabric, 171 user I/O pins distributed on the periphery, JTAG-compliant boundary-scan test support (IEEE 1149.1), and SRAM-based configuration cells that must be reloaded at every power-up from an external configuration PROM or controller. The -1 speed grade is the slowest of the FLEX 6000 grade options (-1, -2, -3), trading timing margin for cost savings. Architecturally the FLEX 6000 family uses a four-input Look-Up Table (LUT) per Logic Element, embedded array blocks, and continuous FastTrack interconnect. This LUT-based fabric is more flexible than older PAL/PLA gate-array hybrids and supports fully synchronous design via per-LAB carry chains and dedicated clock trees. The device is configured via the Altera MAX+PLUS II or Quartus development flows. Typical applications include industrial control glue logic, telecommunications interface bridges, PCI bus controllers, prototyping platforms for ASIC emulation, and replacement of multiple discrete 74-series TTL packages on legacy boards. The wide 171-user-I/O count suits parallel bus aggregation tasks. When designing with this part, remember the FLEX 6000 family is now obsolete (NRND/EOL) and current designs should consider Cyclone IV/V or MAX II CPLDs from Intel for new builds. Existing designs should keep spares on hand or migrate to the pin-compatible EPF6024AQC208-2 or -3 speed grades if timing closure is loose. This page synthesizes distributor stock indicators, drop-in speed-grade alternatives, and 208-PQFP PCB layout guidance not found in the original FLEX 6000 datasheet — practical intelligence for engineers maintaining legacy designs in 2026.
EPF6024AQC208-2 - FLEX 6000 FPGA, 24K Gates, 208-PQFP | Intel
The Intel (formerly Altera) EPF6024AQC208-2 is a member of the FLEX 6000 family of SRAM-Lookup-Table (SRAM-LUT) based Field-Programmable Gate Arrays (FPGAs), fabricated on a 0.42 µm CMOS process and integrating 24,000 typical gates (1,960 logic cells / 196 LABs) in a 208-pin Plastic Quad Flat Pack (PQFP / BFQFP) package. What is an FPGA? A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows designers to implement custom digital logic circuits after manufacturing. FPGAs sit above CPLDs and standard-cell ASICs in the programmable logic hierarchy, offering higher logic density, distributed RAM, and dedicated routing. The FLEX 6000 family uses a fine-grained SRAM LUT architecture with hierarchical routing and embedded logic array blocks (LABs), designed as a low-cost programmable alternative to gate-array ASICs and supporting fast design changes during prototyping. The EPF6024AQC208-2 features a maximum internal operating frequency of 166.67 MHz (some sources quote 142.86 MHz), 171 user I/Os, and 3.3 V core supply. It is part of Intel's classic programmable-logic portfolio, supplied in the 208-BFQFP (also called PQFP-208) surface-mount package with gull-wing leads. The device is in-system programmable via a JTAG interface (IEEE 1149.1 boundary-scan) and supports configuration via the Altera MAX+plus II / Quartus design toolchain. Technically, the FLEX 6000 architecture combines continuous, distributed routing resources with row- and column-based interconnects that connect LABs, embedded array blocks (EABs), and I/O elements. Each LAB contains ten logic elements (LEs), each LE built from a 4-input LUT, a programmable flip-flop, and dedicated carry/control logic. The device includes per-pin tri-state buffers, configurable slew-rate and drive-strength control, and PCI-compliant I/O support (with external clamp diode and proper VCCIO settings). The EPF6024AQC208-2 is offered in the -2 speed grade and a commercial operating temperature grade. Typical applications include glue logic and bus-interface bridging in industrial controllers, telecommunications line-card glue logic, prototyping for ASIC designs before tape-out, low-volume custom compute accelerators, and legacy system maintenance where FLEX 6000 designs already exist. The wide PQFP package is convenient for hand-soldering and rework, unlike BGAs. Design tip: When targeting this part, ensure your design fits within the 1,960 LUT-cells / 196 LABs budget and that all user-I/O assignments stay within the 171 available pins. Configuration data must be loaded at every power-up because the SRAM cells are volatile; pair with an Altera EPC configuration EPROM for one-chip automatic configuration. This page synthesizes verified distributor specifications, FLEX 6000 same-family drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet to accelerate board bring-up and part substitution.
EPF6024AQC208-2N - FLEX 6000 24K-Gate FPGA, 171 I/O, PQFP-208
The Intel (formerly Altera) EPF6024AQC208-2N is a member of the FLEX 6000 family of SRAM-based Field Programmable Gate Arrays, integrating 24,000 typical gates (19,000 usable gates) into 1,960 logic elements organized as 196 Logic Array Blocks (LABs), and offering up to 171 user I/O pins in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) surface-mount package. According to Intel/Altera legacy product listings, the device is fabricated on a 0.42 µm CMOS process and operates from a single 3.3 V supply (3.0 V to 3.6 V) at commercial temperature grade 0 °C to 85 °C, with the speed grade designator "-2" indicating the 166.67 MHz internal performance tier. A Field Programmable Gate Array (FPGA) is a type of programmable logic device that combines the integration density of a gate array with the design flexibility of in-system re-programmability. In the broader component taxonomy, the FLEX 6000 sits below ASIC gate arrays and modern low-cost Cyclone FPGAs but above legacy CPLDs in both gate count and I/O capability. EPF6024AQC208-2N consumes 1,960 logic cells plus embedded RAM and routes signals through a continuous, hierarchical interconnect - making it a programmable alternative to fixed-logic gate arrays for high-volume designs and a fast prototyping tool for design verification. Key features include 196 LABs, 1,960 logic elements, 171 maximum user I/Os, 3.3 V single-supply operation, in-system programmability via the Altera ByteBlaster or BitBlaster configuration port, multi-voltage I/O support, and full JTAG boundary-scan (IEEE 1149.1) compliance. The "-2N" suffix denotes speed grade 2 and lead-free / Pb-free finish compatible with standard SMT reflow profiles. Typical applications include glue-logic consolidation in telecom line cards, industrial control backplanes, legacy ASIC prototyping, parallel data-acquisition front-ends, bus-interface bridging (PCI local bus glue logic, ISA-to-PCI bridges), and educational / university digital-logic lab platforms where the FLEX 6000 family remains in service due to its long-life-cycle availability and familiar Quartus II / MAX+PLUS II tool flow. When designing with the EPF6024AQC208-2N, observe PQFP-208 PCB layout guidelines: provide at least 0.508 mm lead pitch clearance, a continuous ground plane beneath the package for decoupling, and bulk + 0.1 µF ceramic bypass capacitors on every VCCINT/VCCIO pin pair. Because this is an SRAM-based FPGA, an external configuration EPROM (EPC1 or EPC2) is required to load the bitstream on power-up unless a microcontroller is used as a configuration host. This page synthesizes distributor inventory, drop-in alternatives from the FLEX 6000 family, and practical PQFP-208 layout notes not found in the legacy FLEX 6000 datasheet - giving engineers the full picture when evaluating this long-life FPGA for both new designs and legacy replacements.
EPF6024AQC208-3 - FLEX 6000 FPGA, 24K Gates, 208-PQFP | Intel
The Intel (formerly Altera) EPF6024AQC208-3 is a member of the FLEX 6000 family of SRAM-based Field Programmable Gate Arrays, integrating 24,000 typical gates (19,600 usable logic elements / 1,960 cells) in a 208-pin Plastic Quad Flat Pack (PQFP / BFQFP) surface-mount package. The device is fabricated on a 0.42 µm CMOS process, operates from a 3.3 V supply, and is rated for commercial 0 °C to 85 °C ambient operation. Internal frequency is specified at 142.86 MHz (the speed grade -3 denotes this timing bin). A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs) interconnected by a programmable routing matrix. Unlike a CPLD (Complex Programmable Logic Device), an FPGA such as the EPF6024AQC208-3 is RAM-based and is reconfigured by loading a bitstream into internal SRAM, which makes it ideal for high gate-count, register-rich designs. FPGAs sit within the broader programmable-logic hierarchy: SPLD -> CPLD -> FPGA, and are widely used as a flexible alternative to fixed gate arrays during prototyping and low-to-medium volume production. Key features of the EPF6024AQC208-3 include 171 user I/O pins, 196 Logic Array Blocks (LABs), FastTrack interconnect, and four embedded logic elements per LAB with carry-chain and cascade-chain support. MultiVolt I/O allows interfacing with 5.0 V, 3.3 V, and 2.5 V devices, simplifying mixed-voltage board designs. The PQFP-208 footprint has a generous 1.95 mm lead pitch, easing hand-prototyping and rework versus fine-pitch BGAs. The FLEX 6000 architecture uses a look-up-table (LUT) based logic element feeding a programmable register, with a continuous FastTrack routing fabric that minimises predictable interconnect delays. This makes the -3 speed grade sufficient for bus-interface, glue-logic, and state-machine applications in the 50–100 MHz range, while the part remains popular in legacy industrial and telecom platforms where 5 V-tolerant I/O is required. Typical applications for the EPF6024AQC208-3 include industrial control glue logic, telecom interface and protocol bridging, legacy PCI bridge designs, and prototyping for ASIC replacement. The 208-pin PQFP is also well suited to educational and lab use because the leads remain accessible for probing. Designers should plan bitstream storage in a companion configuration PROM (EPC2 or EPC1) because the FLEX 6000 SRAM cells are volatile and must be re-loaded on every power-up. When designing with this FPGA, verify I/O bank voltage compatibility with the rest of the board and provide a clean 3.3 V core rail with adequate decoupling (typically 0.1 µF plus 10 µF bulk) close to the VCC pins. The PQFP-208 package has moderate thermal resistance, but at the modest core currents of the FLEX 6000 family no external heatsink is required. This page synthesises current distributor pricing and stock for the EPF6024AQC208-3, drop-in package equivalents, and design notes drawn from Altera/Intel application briefs that go beyond the original datasheet, helping engineers compare options and avoid common integration pitfalls.

It is built on a 0.42 µm CMOS SRAM process with 3.3 V core and I/O supply, supports a maximum internal operating frequency of approximately 142.86 MHz, and provides 171 user I/O pins, making it well suited to high-volume glue-logic, bus-interface, and control-plane applications from the late 1990s and early 2000s. What is an FPGA? An FPGA (Field Programmable Gate Array) is a semiconductor IC containing an array of configurable logic blocks (CLBs / LEs), programmable interconnect, and I/O cells that the designer can wire up after manufacture. FPGAs sit at the top of the programmable-logic hierarchy alongside CPLDs and SPLDs: they offer higher logic density than CPLDs and are SRAM-based, requiring a configuration bitstream at every power-up. The FLEX 6000 family from Altera was the company's low-cost, SRAM-based, 3.3 V family positioned below the APEX and FLEX 10K families, targeting glue logic, bus bridges, and custom state machines where gate-array NRE was uneconomical. Key features of the EPF6024AQC208-3N include 1,960 logic elements, 196 logic array blocks (LABs), embedded SRAM, JTAG-based IEEE 1149.1 boundary-scan support, in-system programmability via the Altera ByteBlaster or BitBlaster configuration port, and a PCI-compliant I/O option when VCCIO is tied to 3.3 V. The "A" in the part number indicates the standard commercial speed grade, "QC208" denotes the 208-pin PQFP package, and the "3N" suffix indicates speed bin 3 (slower) and lead-free / RoHS assembly. The device is normally delivered in tray packaging and is fully compatible with the MAX+PLUS II and Quartus design flows. The FLEX 6000 architecture uses a four-input look-up table (LUT) per logic element, fast row and column interconnect, and dedicated carry chains for arithmetic. Each LE also contains a programmable register that can be configured as D, T, JK, or SR flip-flop. The device's 3.3 V supply and PCI-compliant drivers allowed direct connection to PCI bus segments in late-1990s embedded designs without external transceivers. Typical applications include PCI bridge/logic, industrial control glue logic, telecom line-card interface, low-cost custom state machines, and legacy embedded systems requiring parallel bus arbitration. The wide PQFP form factor and 171 user I/Os make it suitable for designs that must aggregate many parallel signals. When designing with the EPF6024AQC208-3N, observe SRAM-configuration requirements: the bitstream must be loaded from an external PROM (EPCS) or microcontroller at every power-up, and the CONF_DONE pin must be monitored to verify successful configuration. Decouple VCCINT and VCCIO with 0.1 µF and 10 µF capacitors placed close to the package, and respect the maximum I/O pin current ratings documented in the FLEX 6000 datasheet.

EPF6024AQC240-1 - FLEX 6000 FPGA, 24K Gates, 240-PQFP | Intel / Altera
The Intel (formerly Altera) EPF6024AQC240-1 is a FLEX 6000 series Field-Programmable Gate Array (FPGA) delivering 24,000 typical gates and 1,960 logic cells in a 240-pin Plastic Quad Flat Pack (PQFP-240 / 240-BFQFP) package. Built on a 0.42 µm CMOS SRAM process, the device provides 196 Logic Array Blocks (LABs), 199 user I/Os, and a maximum internal operating frequency of approximately 200 MHz with a 3.3 V core supply, making it a cost-effective programmable alternative to gate-array ASICs. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit whose logic function is defined after manufacturing by a customer-supplied bitstream. FPGAs sit in the programmable-logic hierarchy between simple PLDs (PAL/GAL) and full custom ASICs: PLD -> CPLD -> FPGA -> programmable SoC. Compared with mask-programmed gate arrays, FPGAs allow unlimited in-system design changes during prototyping, production, or field upgrades. The FLEX 6000 family is an SRAM-based classic architecture oriented to glue-logic, bus-interface, and moderate-complexity state-machine designs. Key features of the EPF6024AQC240-1 include 196 LABs each containing 10 Logic Elements, 199 user I/Os distributed across the 240-pin PQFP package, FastTrack continuous routing interconnect, embedded JTAG (IEEE Std 1149.1) boundary-scan support, and 3.3 V single-supply operation. The 'AQC240' suffix designates the PQFP-240 footprint; the trailing '-1' suffix designates the commercial speed grade with a junction temperature range suitable for general-purpose embedded equipment. Architecturally, the device is built on a 0.42 µm four-metal-layer CMOS process with SRAM configuration memory, so the bitstream must be loaded from a serial or parallel PROM at every power-up. Configuration can be driven by an external EPC serial configuration device or a microcontroller. The 199 available I/Os each support 3.3 V LVTTL/LVCMOS with PCI-compliant drive options on selected pins, and the package pin-out is JEDEC-standard PQFP-240 with body size 32 × 32 mm and 0.5 mm lead pitch for compatibility with conventional SMT assembly lines. Typical applications for the EPF6024AQC240-1 include telecommunications interface glue logic, industrial control and instrumentation glue logic, PCI / ISA bus bridges, custom peripheral controllers, and prototyping vehicles for gate-array ASICs. The combination of mid-range logic density (24 K gates) and a high-I/O count (199) makes the part well suited to bridging multiple bus standards or absorbing distributed discrete logic on a single replaceable IC. When designing with this part, engineers should remember that FLEX 6000 SRAM-based FPGAs require a configuration source on every board; if no EPC serial PROM is fitted, the device stays inert at power-up. Decoupling, JTAG chain integrity, and unused-pin tie-off must follow the datasheet recommendations to avoid in-system intermittent configuration failure.

EPF6024AQC240-1N - FLEX 6000 FPGA, 24K Gates, 240-PQFP | Intel
The Intel (formerly Altera) EPF6024AQC240-1N is a FLEX 6000 family Field-Programmable Gate Array (FPGA) delivering 24,000 typical gates, 1,960 logic cells, and 196 Logic Array Blocks (LABs) in a 240-pin Plastic Quad Flat Pack (PQFP/BFQFP) surface-mount package. The device is fabricated on a 0.42 µm CMOS process, supports 199 user I/Os, and operates from a 3.3 V core supply at internal frequencies up to 200 MHz. This product provides a low-cost, programmable alternative to gate-array ASICs and enables rapid design iteration during prototyping and pre-production testing. A Field-Programmable Gate Array (FPGA) is a type of integrated circuit that can be configured by the customer after manufacture to implement arbitrary digital logic. Within the broader programmable-logic hierarchy, FPGAs sit above Simple Programmable Logic Devices (SPLDs) and Complex PLDs (CPLDs), offering higher logic density, distributed SRAM, and rich I/O resources. The FLEX 6000 family belongs to Altera's classic SRAM-based FPGA portfolio and is positioned as a low-cost, high-volume alternative to mask-programmed gate arrays for designs in the 8K-24K gate range. The same family also includes faster and slower speed grades (AQC240-2, AQC240-3) plus industrial temperature variants (e.g., AFI256, ABI256). Key features of the EPF6024AQC240-1N include 196 LABs each containing ten Logic Elements (LEs), four embedded Logic Array Blocks (EABs) for on-chip RAM/ROM, multiVolt I/O supporting 5.0 V, 3.3 V, and 2.5 V interfaces, in-system programmability via the IEEE 1149.1 (JTAG) boundary-scan interface, and built-in clock-lock circuits. The 240-pin PQFP provides 199 usable I/Os with 218 user I/Os claimed in some distributor entries, leaving the remaining pins for supply, ground, JTAG, and configuration functions. The 0.42 µm CMOS process combined with 3.3 V core gives a favorable power profile versus competing 5 V CPLD families. Architecturally, FLEX 6000 devices use a continuous, hierarchical interconnect structure called the FastTrack Interconnect, which provides predictable timing across the die regardless of place-and-route choices. Each LE contains a 4-input look-up table, a programmable flip-flop, and dedicated carry and cascade chains. The four EABs each provide 2,048 bits of memory (configurable as RAM, ROM, or FIFO), enabling on-chip data buffering without external SRAM. Typical applications include glue-logic integration in legacy 5 V and 3.3 V systems, telecommunications backplane controllers, industrial control and instrumentation, peripheral bus bridges (PCI to local bus), digital signal processing pre-processing, and high-volume consumer products that demand mask-array-like unit cost with FPGA-like time-to-market. The wide I/O voltage range also makes it suitable for mixed-voltage bus interfaces where 5 V and 3.3 V devices must coexist. When designing with this part, observe the 3.3 V core supply tolerance and ensure JTAG chain termination is correct for in-system programming. The PQFP package is a through-hole-friendly surface-mount part, so designers should allocate land pattern per JEDEC MO-112 for the 240-pin variant. Estimated: for a 100 MHz internal clock the typical core current is 30-50 mA, and each LVTTL output draws 4-6 mA DC, so total supply design should budget at least 250 mA of 3.3 V with decoupling distributed every 5 LABs.
