EPF6024ABC256-2N - FLEX 6000 24K Gate FPGA | Intel | BGA-256

The Intel (formerly Altera) EPF6024ABC256-2N is a member of the FLEX 6000 family of Field Programmable Gate Arrays (FPGAs) providing 24,000 gates, 1,960 logic cells (logic elements), and 218 user I/O pins in a 256-ball BGA package, operating from a 3.3 V supply. It is fabricated on a 0.42 µm CMOS process and targets low-cost, high-volume programmable logic replacement of fixed gate arrays with internal performance up to 172 MHz. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the high integration of a gate array with the design flexibility of in-system programmability. Within the broader programmable logic hierarchy, FPGAs sit above simple PLDs (SPLDs) and complex PLDs (CPLDs), providing the highest logic density and the most flexible interconnect. The EPF6024A sits in the FLEX 6000 mid-density tier of legacy Altera devices, positioned between small glue-logic CPLDs and the higher-density FLEX 10K / APEX families. Key features of the EPF6024ABC256-2N include 196 Logic Array Blocks (LABs), JTAG Boundary Scan Test (BST) support, slew-rate controlled I/O, tri-state output buffers, and built-in PCI compliance for some I/O standards. The device supports setup times as low as 2 ns and zero hold times via the FastTrack interconnect, allowing it to be used in moderate-speed control, bus-interface, and bridging applications. From a technical architecture standpoint, the EPF6024A combines four-input look-up table (LUT)-based logic elements, embedded array blocks (EABs) for memory functions, and a continuous FastTrack routing network. The 256-ball BGA package (BC256 designation) gives the highest I/O count in the family and is targeted at high-density glue-logic, peripheral bus bridging, and prototype-to-production conversion tasks. The "-2N" speed grade and "C" temperature grade (commercial 0 °C to 85 °C) make it suitable for industrial and commercial environments. Typical applications include PCI bus interface glue logic, peripheral bus bridges (e.g., ISA-to-PCI, local bus expansion), telecommunication line-card control logic, industrial machine control, and high-volume consumer electronics requiring fast design changes during prototyping. The 218 user I/Os make it attractive for parallel bus and memory-interface bridging. When designing with this part, note that it is a legacy device currently in the obsolete/EOL phase of its lifecycle. Designers should verify long-term availability, plan for second-source alternatives, and check that the MAX+PLUS II or Quartus design tools still support the chosen package variant before committing to new designs.

EPF6024ABC256-3

EPF6024ABC256-3 - FLEX 6000 FPGA, 24K Gates, 256-BGA | Altera

The Altera EPF6024ABC256-3 is a member of the FLEX 6000 family of Field-Programmable Gate Arrays (FPGAs), providing 24,000 typical gates, 1,960 logic cells, and 218 user I/Os in a 256-ball BGA package. The device operates from a 3.3 V supply, runs up to 142.86 MHz internal frequency, and is fabricated on a 0.42 µm CMOS process. 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. The device supports JTAG-based configuration and the Altera EPC configuration devices for serial/parallel loading of the SRAM configuration memory. 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

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.

EPF6024AFC256-1

EPF6024AFC256-1 - FLEX 6000 FPGA, 24K Gates, 256-BGA | Intel

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.

EPF6024AFC256-2AA

EPF6024AFC256-2AA - 24K Gates FLEX 6000 FPGA 256-BGA | Altera

The Altera EPF6024AFC256-2AA is a member of the FLEX 6000 family of Field Programmable Gate Arrays (FPGAs) featuring 24,000 gates, 1,960 logic cells, and 218 user I/Os in a 256-ball Fine-pitch BGA (FBGA) package measuring 17x17 mm. Manufactured on a 0.42 micrometer CMOS process, the device operates from a 3.0 V to 3.6 V supply and supports an internal frequency of 166.67 MHz, targeting low-cost, high-volume programmable logic applications where fast design changes during prototyping are essential. An FPGA (Field Programmable Gate Array) is a reconfigurable semiconductor containing an array of programmable logic blocks, interconnect, and I/O cells that engineers can customize after manufacturing using HDL (Hardware Description Language) bitstreams. FPGAs occupy the middle ground between fixed-function ASICs and software-driven processors, offering parallel hardware execution, deterministic latency, and the ability to be reprogrammed in-circuit. Within the broader taxonomy, the EPF6024AFC256-2AA is a SRAM-based LUT (Look-Up Table) FPGA, the most flexible and re-programmable sub-class, sitting under programmable logic -> logic IC -> integrated circuit -> semiconductor. Key parametric features of the EPF6024AFC256-2AA include 218 maximum user I/O pins (high I/O density for a low-cost device), 1,960 logic elements, an embedded array block for implementing wide combinational functions such as FIFOs and RAM, and in-system programmability through the IEEE 1149.1 (JTAG) interface and Altera's passive serial configuration mode. 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.

EPF6024AFC256-3

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.

EPF6024AFI256-2 - 24K Gates FLEX 6000 FPGA, 256-BGA | Intel

The Intel EPF6024AFI256-2 is a member of the FLEX 6000 family of SRAM-based field programmable gate arrays (FPGAs) delivering 24,000 typical gates, 1,960 logic elements, and 196 I/Os in a 256-ball fine-pitch BGA (FBGA) package. Operating at 5.0V core with 0.42 µm CMOS process technology, the device supports system clock rates up to 166.67 MHz and provides a register-rich, look-up-table (LUT) based OptiFLEX architecture optimized for low-cost, high-volume gate array replacement and rapid prototyping with fast design changes. 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; FPGAs are widely used to implement custom digital logic, glue logic, and prototyping for ASIC designs. The FLEX 6000 family sits at the low-cost, register-rich end of the Altera/Intel FPGA portfolio, well suited to applications where high gate count and low unit cost are both required. Within the broader taxonomy, the EPF6024AFI256-2 belongs to: FLEX 6000 family -> Altera/Intel FPGA -> programmable logic device (PLD) -> integrated circuit -> semiconductor. Key specifications include 24,000 typical gates, 1,960 logic elements (LEs), 196 user I/Os, 5.0V nominal core supply, and pin compatibility across the FLEX 6000 family package options. 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

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.

EPF6024AQC208-1 - FLEX 6000 24K Gates 200MHz FPGA | Intel (Altera)

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.

EPF6024AQC208-1N

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.

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.

EPF6024AQC208-3N

EPF6024AQC208-3N - FLEX 6000 FPGA, 24K Gates, 208-PQFP | Intel

The Intel (formerly Altera) EPF6024AQC208-3N is a member of the FLEX 6000 family of Field Programmable Gate Arrays (FPGAs), delivering 24,000 typical gates (19,000 usable gates) and 1,960 logic elements in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. 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. This page synthesizes distributor pricing from DigiKey, Mouser, Arrow, Octopart and Heisener, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, giving an engineer a single consolidated reference for legacy FLEX 6000 designs.

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. This page synthesizes distributor pricing, same-brand and cross-brand drop-in alternatives, and practical design notes not found in the original datasheet, including explicit selection guidance between FLEX 6000 speed grades and package variants.

EPF6024AQC240-2S - FLEX 6000 FPGA 24K Gates 240-PQFP | Altera

The Altera EPF6024AQC240-2S is a member of the FLEX 6000 family of Field-Programmable Gate Arrays (FPGAs) providing 24,000 typical gates, 1,960 logic elements (cells), and 196 logic array blocks (LABs) housed in a 240-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. Built on a 0.42 µm CMOS SRAM process and operating from a 3.3 V supply, the device is fabricated on the OptiFLEX architecture which minimizes die size while preserving high performance and routability. The -2 speed grade targets a maximum clock frequency of 166.67 MHz, making it suitable for glue-logic, bus-interface, and medium-complexity state-machine designs. A Field-Programmable Gate Array (FPGA) is a class of programmable logic device (PLD) that combines the density of a gate array with the in-system reprogrammability of an SRAM-based lookup table. Within the wider semiconductor taxonomy, an FPGA sits between low-density CPLDs and mask-programmed ASIC gate arrays; FPGAs are typically chosen when NRE cost is too high for an ASIC but density or performance exceeds what a CPLD can deliver. The FLEX 6000 family was Altera's low-cost, high-volume alternative to traditional gate-array designs. Key features of the EPF6024AQC240-2S include 199 user I/O pins (one of the largest user-I/O counts in the FLEX 6000 family), four embedded logic array blocks implementing 24 logic elements each, SRAM-based configuration cells that allow in-system re-programming via JTAG, and built-in PCI compliance support. MultiVolt I/O allows interface to 5.0 V, 3.3 V, and 2.5 V buses without external level shifters, while in-system programmability (ISP) via the IEEE 1149.1 boundary-scan interface reduces manufacturing test cost and enables field firmware updates. The PQFP-240 package exposes the maximum I/O available in the family. Architecturally, the OptiFLEX structure routes signals through continuous horizontal and vertical pass-transistor lines that connect every LAB to every other LAB; this shortens typical interconnect delays and removes the segmented routing hierarchy used in competing families. Configuration data is stored in SRAM cells and is loaded from an external serial PROM or via JTAG on power-up, after which the device operates deterministically until the next reconfiguration. The device is fabricated on a 0.42 µm four-layer-metal CMOS process. Typical applications include telecommunications line cards, industrial control and glue logic, PCI bus bridges, peripheral controllers, low-to-medium density DSP co-processors, and legacy retrofits for systems originally designed around mask-programmed gate arrays. The 240-pin PQFP with 199 user I/Os is a strong fit when a board needs to fan out to many parallel buses or memory interfaces. Industrial, telecom, and embedded computing segments continue to use FLEX 6000 devices for cost-sensitive, mature-platform designs. When designing with this part, verify PCI compliance timing margins if used in 33 MHz PCI applications, allow sufficient inrush current headroom on the 3.3 V rail for configuration, and pair it with an EPC configuration PROM for standalone power-up. The PQFP-240 footprint requires careful thermal management at high toggle rates, since the plastic package has limited heat dissipation compared to the BGA options available in later FLEX families.

EPF6024AQC240-3 - FLEX 6000 FPGA 24K Gates 240-BFQFP | Intel

The Intel (formerly Altera) EPF6024AQC240-3 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 in a 240-pin Fine-pitch Ball Grid Array / Quad Flat Pack (240-BFQFP) package. The device operates at 3.3V core supply using 0.42 µm CMOS technology with a maximum internal frequency of 142.86 MHz, providing 199 user I/O pins for high-density glue-logic and bus-interface applications. What is an FPGA? A Field-Programmable Gate Array is a programmable logic device (PLD) containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, all of which are defined after manufacture by a bitstream loaded into on-chip SRAM. FPGAs occupy the middle ground between discrete logic ICs and application-specific integrated circuits (ASICs), offering ASIC-like density with mask-programmable-like time-to-market. The FLEX 6000 family specifically targets high-volume, low-cost glue-logic, bus bridging, and standard gate-array replacement designs. Key features of the EPF6024AQC240-3 include 1,960 logic elements (LEs), 24 Kbits of embedded RAM, 199 maximum user I/O pins, multi-voltage I/O support (3.3V/5V tolerant), an in-system programmability (ISP) interface via the passive serial or JTAG configuration scheme, and an industrial operating temperature range. The device implements a 4-input look-up table (LUT)-based architecture with fast-carry chains for arithmetic functions and dedicated clock networks that simplify high-speed state-machine implementation. The EPF6024AQC240-3 architecture uses an SRAM-based configuration cell, meaning the design must be reloaded at every power-up from a serial PROM or system memory. The 0.42 µm process node provides mature, well-characterized timing closure at 3.3V core supply and supports the IEEE 1149.1 (JTAG) boundary-scan test standard. The 240-BFQFP package (body size 32 mm x 32 mm, 0.5 mm lead pitch) is suitable for through-hole-style surface mounting on 1.0 mm-thick PCBs. Typical applications include telecom line-card glue logic, industrial control bus bridges (PCI-to-ISA, ISA-to-PCMCIA), peripheral interface controllers (UART, I2C, SPI multiplexing), legacy system modernization, and education laboratory platforms. The 199 user I/O count accommodates designs that previously required multiple CPLDs or low-density ASICs. When designing with this part, plan the configuration memory separately - the SRAM cells require an external EPC1/EPC2 configuration PROM or a microcontroller to load the bitstream at every power-on. Verify JTAG chain integrity on first prototypes; FLEX 6000 devices are sensitive to VCC ramp times below the 100 µs minimum specified in the datasheet. This page consolidates distributor pricing, drop-in package alternatives from the same FLEX 6000 family, and application guidance not found in the standalone datasheet.

EPF6024AQC240-3 - FLEX 6000 FPGA, 24K Gates, 240-PQFP | Intel

The Intel / Altera EPF6024AQC240-3 is a member of the FLEX 6000 family of programmable logic devices (PLDs), offering 24,000 gates and 199 user I/Os in a 240-pin PQFP package with 3.3 V core supply. It is fabricated in a 0.42 µm CMOS process with SRAM-based configuration memory and delivers an internal operating frequency of 142.86 MHz. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit based on a matrix of configurable logic blocks (CLBs) connected via programmable interconnect. FPGAs belong to the broader class of programmable logic devices (PLDs), which sit within digital logic ICs and integrated circuits. Unlike fixed-function ASICs, FPGAs allow designers to implement custom digital logic, glue logic, state machines, bus bridges, and parallel processing pipelines that can be reconfigured in-system via SRAM configuration memory. The FLEX 6000 family uses Altera's OptiFLEX architecture, which minimizes die size while preserving routability and performance. Key features of the EPF6024AQC240-3 include 1,960 logic cells, 196 logic array blocks (LABs), a 3.0 V to 3.6 V single-supply operating range, and reconfigurable SRAM elements that allow rapid design iteration during prototyping. The device is intended as a low-cost, high-volume alternative to mask-programmed gate arrays for production volumes that do not justify ASIC NRE. Architecturally, the EPF6024AQC240-3 integrates distributed SRAM configuration memory with a hierarchical routing fabric, I/O elements (IOEs) supporting common single-ended standards, and dedicated clock networks. The 240-pin PQFP (also referred to as 240-BFQFP) package offers 199 usable user I/Os after accounting for power, ground, JTAG, and configuration pins, making it suitable for medium-density glue-logic and bus-interface designs. Typical applications include telecommunications glue logic, industrial control interfaces, PCI bus bridging, peripheral expansion in embedded systems, and prototyping of ASIC-equivalent designs where fast design turnaround is more valuable than absolute lowest unit cost. The 3.3 V supply also simplifies integration into 3.3 V-only embedded platforms without level shifting. When designing with this device, allocate sufficient decoupling (0.1 µF + bulk) near every supply pin and follow Altera's Quartus / MAX+PLUS II configuration guidelines for the JTAG and configuration pins. Note that FLEX 6000 SRAM-based devices require configuration at every power-up, so the EPF6024AQC240-3 is paired with a configuration PROM or microcontroller in production designs.

The PQFP-240 footprint supports surface-mount assembly with standard JEDEC-compliant handling. From an architectural standpoint, the device integrates each logic element as a 4-input LUT with a programmable register, and each LAB groups 16 logic elements with control signals for fast carry chains and cascade chains. The interconnect is a continuous, fast-path routing network with low-skew clock distribution, enabling predictable timing closure at the rated 133 MHz fmax. The configuration memory is SRAM-based, requiring external configuration storage on every power-up. Typical applications include industrial control glue logic, telecom interface bridging, peripheral bus arbitration, legacy ASIC replacement, prototyping of custom gate arrays, and high-volume cost-sensitive designs where the FLEX 6000 family targets gate-array price points. The wide I/O count also makes the part suitable for memory-mapped interfaces between microprocessors and peripherals. When designing with this FPGA, ensure that the configuration device (e.g., EPC2 or compatible serial EEPROM) is properly selected for SRAM-based FLEX 6000 devices, and verify that the JTAG chain includes the EPF6024AQC240-3N for boundary-scan testing. Designers migrating to newer Intel/Altera Cyclone families must consider that the FLEX 6000 is a legacy product and should plan for long-term availability before committing to new designs. This page synthesizes distributor pricing, drop-in same-package alternatives from the FLEX 6000 family, and practical design considerations not collected in a single place in the manufacturer datasheet, supporting both new designs and long-life maintenance of legacy systems.

EPF6024AQC240-3S - 24K Gates FLEX 6000 FPGA | Altera | QFP-240

The Altera (now Intel) EPF6024AQC240-3S is a member of the FLEX 6000 family of Field-Programmable Gate Arrays (FPGAs), featuring 24,000 typical gates and 1,960 logic cells in a 240-pin Plastic Quad Flat Pack (PQFP/BFQFP) surface-mount package. It is built on a 0.42 µm CMOS SRAM-based OptiFLEX architecture and operates from a 3.3 V supply with 199 user I/O pins, targeting high-volume, low-cost gate-array replacement and rapid-prototyping applications. A Field-Programmable Gate Array (FPGA) is a reconfigurable semiconductor device in the programmable logic family that sits below application-specific integrated circuits (ASICs) in the silicon hierarchy: FPGA -> PLD (Programmable Logic Device) -> programmable logic -> logic IC -> semiconductor. FPGAs contain an array of configurable logic blocks (LABs in Altera terminology), programmable interconnects, and I/O cells, all controlled by SRAM configuration memory. Unlike CPLDs which use non-volatile EEPROM, FPGAs must be reconfigured at every power-up from an external ROM, allowing unlimited in-system design iterations. Key specifications include a maximum internal frequency of 172 MHz, 196 Logic Array Blocks (LABs), 199 usable I/O pins, and a typical gate count of 24,000 (with up to 28,000 maximum). The device uses 4-input look-up tables (LUTs) per logic element and supports in-system programmability via the IEEE 1149.1 JTAG boundary-scan interface. The OptiFLEX architecture minimizes die size while preserving routing density, making the FLEX 6000 family the most cost-optimized FPGA line in the Altera catalog at the time of release. The EPF6024AQC240-3S uses an SRAM-based configuration cell, which means the design must be loaded from an external EPC configuration PROM or microcontroller at every power-on. This architecture provides unlimited reprogram cycles, ideal for design prototyping, field upgrades, and low-to-mid volume production. The -3S speed grade denotes the commercial 0 °C to 85 °C operating range with a faster timing bin than the -2 or -1 grades. Typical applications include telecommunications line cards, industrial control glue logic, video processing front-ends, legacy PCI bridge designs, and ASIC prototyping for low-complexity state machines. Designers select FLEX 6000 devices when the design needs SRAM-based reconfigurability, more logic capacity than a CPLD can provide, and a 3.3 V supply rail compatible with older ASICs and microprocessors. Design consideration: ensure the configuration PROM (such as EPC1 or EPC2) is correctly sized for the EPF6024AQC240-3S bitstream and that the JTAG chain order does not conflict with any boundary-scan devices on the board. The PQFP-240 footprint requires fine-pitch PCB routing (0.5 mm pitch) and careful thermal management — the plastic package does not have an exposed pad, so most heat must be removed through the lead frame and copper pours. This page synthesizes datasheet specifications, current distributor pricing, drop-in same-brand alternatives, and design considerations not found in the standalone manufacturer datasheet, providing a single reference for engineers evaluating the EPF6024AQC240-3S for new designs or legacy board maintenance.
