The Intel (formerly Altera) EPF6024AQC240-2 is a member of the FLEX 6000 family of SRAM-based Field-Programmable Gate Arrays (FPGAs), integrating 24,000 typical gates, 1,960 logic cells, and 196 Logic Array Blocks (LABs) into a 240-pin Power Quad Flat Pack (PQFP/BFQFP) surface-mount package. Fabricated on a 0.42 µm CMOS process and operating from a 3.3 V supply, the device supports internal frequencies up to 166.67 MHz (with 172 MHz noted on some distributor listings) and offers 199 user I/Os across its 240-pin footprint, providing an ideal low-cost, programmable alternative to high-volume gate array applications. A Field-Programmable Gate Array (FPGA) is a programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs/LABs), programmable interconnect, and programmable I/O cells. The FLEX 6000 family sits within the broader hierarchy of programmable logic devices (PLD -> CPLD/FPGA -> SRAM-based FPGA -> FLEX 6000 series -> EPF6024 device), designed for glue logic, bus interfacing, and moderate-density state-machine designs in industrial and communication equipment. Modern SRAM-based FPGAs are volatile and require an external configuration PROM at power-up. Key features of the EPF6024AQC240-2 include 24,000 typical gates (with up to 28,000 maximum), 1,960 logic elements, 196 LABs, 4,992 RAM bits, and 199 usable I/Os. The device is built on a 0.42 µm four-layer metal CMOS process, supports in-system programmability via the IEEE 1149.1 (JTAG) interface, and integrates JTAG boundary-scan test logic. Speed grade -2 places this part in the commercial speed-performance tier relative to the -1 and -3 grades. The FLEX 6000 architecture combines fast interconnect with Look-Up Table (LUT)-based logic elements and embedded memory, making it suitable for register-intensive designs, custom peripheral interfaces, and DSP pre/post-processing. Combined with Altera Quartus and MAX+PLUS II development tools, designers can implement complex glue logic, bridging functions, and high-performance state machines with low unit cost. Typical applications include telecommunications line-card interface logic, industrial control and instrumentation, ASIC prototyping, and legacy system migration paths. The wide I/O count supports bus bridging (e.g., PCI to local bus), custom peripheral controllers, and high-speed glue logic between microprocessors and memory subsystems. When designing with the EPF6024AQC240-2, plan the configuration memory interface (EPC configuration device or JTAG) at board bring-up. The 240-pin PQFP footprint allows hand-rework and inspection, but engineers targeting lower-power or higher-density logic should consider migrating to Cyclone or MAX series devices.

EPF6024AQC240-2N - 24K Gates FLEX 6000 FPGA, 240-PQFP | Intel
The Intel (formerly Altera) EPF6024AQC240-2N is a member of the FLEX 6000 family of SRAM-based Field Programmable Gate Arrays (FPGAs), offering 24,000 gates, 1,960 logic cells, and 196 Logic Array Blocks (LABs) in a 240-pin Plastic Quad Flat Pack (PQFP) package. It operates at up to 166.67 MHz internal frequency on a 0.42 µm CMOS process at a 3.3 V core supply, providing 199 user I/O pins for high-pin-count glue-logic and co-processing applications. An FPGA (Field Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs or LABs), programmable interconnect, and I/O cells. Unlike an ASIC, an FPGA's function is defined after manufacturing via a configuration bitstream loaded into on-chip SRAM, allowing rapid design iteration. The FLEX 6000 family sits within Intel/Altera's broader programmable logic hierarchy as a low-cost, 3.3 V alternative to higher-density FLEX 10K and APEX families, ideal for high-volume gate-array replacement and prototyping. Key features of the EPF6024AQC240-2N include a 199-pin user I/O count (one of the highest pin counts in the FLEX 6000 line), 1,960 logic cells distributed across 196 LABs, embedded SRAM-based configuration, JTAG-based boundary-scan test support, and operation across 0 °C to 85 °C commercial temperature range. The 240-pin PQFP package offers reliable through-hole-style surface-mount assembly on standard PCB footprints. Architecturally, the device pairs each LAB with an Embedded Array Block (EAB) for implementing RAM, ROM, or multiplier functions, and uses a continuous FastTrack interconnect routing fabric. MultiVolt I/O pins accept 3.3 V and 5 V signaling for mixed-voltage system integration, while the 0.42 µm CMOS process delivers a favorable cost-per-gate for volume production. Typical applications include telecommunications line cards, industrial control glue logic, legacy peripheral bridges, prototyping platforms, and cost-sensitive replacement of fixed-logic gate arrays. Designers migrating from discrete TTL or low-density PLDs benefit from 1,960 logic cells and 199 I/Os in a single device. When designing with this part, note that configuration bitstream must be loaded from external ROM at every power-up due to SRAM-based architecture, and unused I/Os should be tri-stated to minimize switching current.

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.

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. This page synthesizes distributor pricing, drop-in pin-compatible alternatives from the same FLEX 6000 family, and practical design notes not found in the manufacturer datasheet.

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.

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.

EPF6024AQC240-4N - FLEX 6000 FPGA, 24K Gates | Intel (Altera)
The Intel (formerly Altera) EPF6024AQC240-4N is a member of the FLEX 6000 family of CMOS SRAM-based Field-Programmable Gate Arrays (FPGAs), providing up to 24,000 typical gates in a 240-pin PowerQuad Flat Package (PQFP-240). The "-4" speed grade denotes the fastest available in the family, and the "N" suffix indicates a lead-free / Pb-free finish. The FLEX 6000 family uses a fine-grained Look-Up Table (LUT) architecture with continuous routing and OptiFLEX expansion, targeting low-cost, high-volume programmable logic designs where fast design changes during prototyping are required. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that lets designers configure digital logic through a four-step flow (design entry, place-and-route, simulation, programming) without fabricating a custom ASIC. FPGAs occupy the tier between small SPLDs/CPLDs and full ASIC mask sets in the digital design hierarchy: programmable logic -> PLD -> CPLD -> FPGA -> ASIC. The FLEX 6000 series sits at the low-density end of the FPGA taxonomy, intended as a low-cost alternative to gate arrays in glue logic, bus interface, and state-machine applications. Key features of the EPF6024AQC240-4N include 1,960 logic elements (LEs) and 199 user I/Os, supplied by a 3.3 V core supply with 5 V-tolerant I/O. The device is configured via the IEEE 1149.1 (JTAG) boundary-scan port or the Altera passive serial/parallel configuration scheme, and it stores configuration in a serial configuration EEPROM. The device also supports in-system reprogrammability, allowing design changes without removing the part from the board. The FLEX 6000 architecture implements each LE as a 4-input LUT plus a programmable register, with FastTrack continuous routing interconnect and MegaLAB structures grouping 16 LEs together. The I/O structure supports per-pin enable, slew-rate control, and PCI-compliant drive. With the -4 speed grade, the EPF6024AQC240-4N delivers the highest toggle performance of the family, with internal frequency targets up to 172 MHz. Typical applications include bus-interface bridges (e.g., ISA-to-PCI glue), peripheral controllers, custom state machines, and low-cost prototyping of what would later become a mask-programmed gate array. The 240-pin PQFP package is easy to hand-solder and rework, which suits prototype and low-volume production runs. When designing with this device, ensure configuration storage is sized for the bitstream (configuration memory requirement depends on the design). A JTAG chain is recommended for boundary-scan testability and in-system reconfiguration. Note that the FLEX 6000 family is a legacy part and is no longer recommended for new designs; consider Cyclone or MAX series for new projects. This page synthesizes distributor pricing, same-package drop-in alternatives from the FLEX 6000 family, and practical design notes not found in the manufacturer datasheet.

The Altera (now Intel) EPF6024AQC240-5 is a member of the FLEX 6000 family of SRAM-based field programmable gate arrays (FPGAs) housed in a 240-pin BQFP (plastic quad flat pack) package. The device integrates approximately 24,000 typical gates (equivalent), 1,960 logic elements arranged across 196 logic array blocks (LABs), and 199 user I/O pins. The "-5" speed grade denotes the slowest commercial timing variant within the FLEX 6000 family, trading absolute clock frequency for lower cost in non-time-critical glue-logic applications. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that allows designers to implement arbitrary digital logic through a configuration bitstream loaded into on-chip SRAM. FPGAs occupy a middle ground between fixed-function ASICs (application-specific integrated circuits) and small PLDs such as CPLDs (complex programmable logic devices): unlike ASICs they are reprogrammable in the field, and unlike most CPLDs they offer far higher logic density and embedded memory. The FLEX 6000 family in particular targets cost-sensitive glue-logic, bus-interface bridging, and I/O expansion use cases where high register counts and moderate I/O bandwidth matter more than raw clock rate. Key specifications of the EPF6024AQC240-5 include the 240-BQFP surface-mount package with a body size of approximately 32 mm × 32 mm, 199 available user I/O pins, and 1,960 logic elements distributed over 196 LABs. The "QC" package suffix indicates a commercial-temperature-range plastic QFP, while "240-5" indicates the 240-pin count and the slowest speed grade. The device operates from a 5 V core supply typical of late-1990s / early-2000s logic designs and supports configuration via Altera's serial or parallel configuration schemes. Architecturally, the FLEX 6000 family uses a continuous-routing interconnect with distributed look-up table (LUT) logic and dedicated I/O elements. Each LAB contains multiple logic elements, and I/O pins support a range of standards including TTL and CMOS at 3.3 V or 5 V. Embedded array blocks (EABs) provide on-chip ROM/RAM capability for small memory functions, eliminating the need for external memory in many glue-logic designs. Typical applications for the EPF6024AQC240-5 include industrial glue-logic and bus-bridging boards, legacy telecommunications backplane controllers, military and avionics retrofits that require pin-compatible extended-temperature variants, and prototype ASIC emulation where the 24K-gate density matches the target design. Engineers frequently choose this part for long-lifecycle industrial control systems designed in the late 1990s that are still in production today. When designing with this device, note that the FLEX 6000 family has reached end-of-life status and is no longer recommended for new designs; designers should evaluate Cyclone or MAX families as modern replacements. Confirm long-term supply and counterfeit risk before specifying in new production, and use the Altera / Intel configuration toolchain (Quartus) for bitstream generation. This page synthesizes drop-in alternatives, distributor pricing, and design considerations not found in the original manufacturer datasheet - giving engineers a faster path to second-source qualification or legacy board rework.

The device is organized as 196 Logic Array Blocks (LABs), each containing 10 Logic Elements, and supports continuous FastTrack interconnect across rows and columns. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) containing an array of configurable logic blocks (CLBs), programmable interconnect, and programmable I/O cells, all controlled by on-chip SRAM configuration memory. FPGAs sit at the top of the programmable logic hierarchy: PLD -> CPLD/FPGA -> SRAM-based FPGA -> FLEX 6000 family. FPGAs offer higher logic density and richer interconnect than older CPLDs, at the cost of requiring external configuration memory and a multi-step power-on sequence. Key features of the EPF6024AQC240-6 include 24,000 typical gates, 1,960 logic elements, 196 LABs, 199 maximum user I/Os, JTAG-based IEEE 1149.1 boundary-scan test support, multi-voltage I/O (3.3 V with 5.0 V tolerance via pull-up), and a built-in configuration memory controller. Speed grade 6 indicates the slowest timing bin of the FLEX 6000 family, which trades maximum Fmax for the most favorable cost tier - appropriate for cost-sensitive industrial and embedded designs that do not need the highest clock rates. Typical applications include glue logic in industrial control systems, custom peripheral expansion for legacy microprocessors, telecommunications line-card interface logic, prototyping bridges for ASIC designs, and bus-protocol converters (e.g., ISA-to-local bus, UART muxing, parallel-to-serial aggregation). The 240-pin PQFP footprint makes hand-rework and socketed prototyping easier than BGA alternatives. When designing with the EPF6024AQC240-6, ensure your configuration PROM and clock-distribution network meet FLEX 6000 power-on sequencing requirements (VCCIO before VCCINT, then CONFDONE assertion). The 240-PQFP package has relatively long leads that aid inspection but limit high-speed signal lengths, so follow Altera application-note layout guidelines for clocks and global signals.

EPF6024AQC2403N - 24K Gates FLEX 6000 FPGA | Intel / Altera
The Intel / Altera EPF6024AQC2403N is a 24,000-gate FLEX 6000 family Field Programmable Gate Array (FPGA) housed in a 240-pin Plastic Quad Flat Pack (PQFP / BFQFP) package. Built on the OptiFLEX architecture and fabricated on a 0.42 µm SRAM-based process, the device integrates 1,960 logic elements with 199 maximum user I/O pins, supplying 142.86 MHz internal performance at 3.3 V core supply. A field programmable gate array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs) connected via programmable interconnect and surrounded by programmable I/O cells. FPGAs belong to the broader category of programmable logic devices (PLDs), which also includes CPLDs and SPLDs. Within modern electronics, FPGAs sit between fixed-function ASICs and software-driven microcontrollers, offering hardware-timed parallelism, reprogrammability in the field, and gate counts ranging from a few thousand to millions of logic elements. Key features of the EPF6024AQC2403N include reconfigurable SRAM configuration memory, multi-voltage I/O support (3.3 V with 5.0-V tolerance when a pull-up resistor is used), and built-in JTAG-based in-system programmability. The device supports both 5.0-V and 3.3-V I/O standards on the same package, and the IOL current specification must be considered when sizing pull-up resistors on 5.0-V-tolerant outputs. The OptiFLEX architecture minimizes die size while maintaining high performance and routability, which makes the FLEX 6000 family a low-cost alternative to high-volume gate array designs. Typical use cases include glue logic replacement, custom peripheral interfacing, bus bridging, and low-volume ASIC prototyping. The wide 199-I/O budget suits parallel data acquisition and bus-aggregation designs, while the SRAM configuration supports frequent in-field firmware revisions. Industrial control front-ends and telecom line-card glue logic remain common sockets. When designing with this part, validate configuration mode and JTAG chain ordering against the FLEX 6000 family datasheet, and verify timing closure using the Quartus II or MAX+PLUS II tool flow. The 3.3-V core with 5.0-V-tolerant I/O simplifies mixed-voltage board designs without external level shifters on most signals. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not consolidated in the Altera FLEX 6000 datasheet, helping engineers shorten the sourcing and qualification cycle.
EPF6024AQC280-3 - FLEX 6000 FPGA 24K Gates QFP-280 | Intel / Altera
The Intel / Altera EPF6024AQC280-3 is a member of the FLEX 6000 programmable logic device family that delivers approximately 24,000 usable gates in a 280-pin Plastic Quad Flat Pack (PQFP) package. The "-3" speed grade places it in the mid-tier of the family, balancing timing margin against cost for cost-sensitive glue-logic and bus-interface applications. The device is fabricated on a 0.35 um CMOS SRAM process and is in-system programmable via the IEEE 1149.1 (JTAG) boundary-scan interface. What is a FLEX 6000 device? The FLEX 6000 family is Altera's second-generation fine-grained SRAM-based programmable logic family, sitting in the taxonomy: programmable logic -> CPLD/FPGA -> SRAM-based FPGA -> FLEX architecture -> FLEX 6000 sub-family. It combines Look-Up Table (LUT)-based logic elements with a continuous FastTrack interconnect, providing true FPGA density while retaining predictable routing delays. FLEX 6000 parts were positioned as low-cost, high-volume alternatives to gate-array ASICs in the late 1990s and early 2000s. Key features of the EPF6024AQC280-3 include 2,560 logic elements (LEs), 24,000 typical gates, 196 I/O pins available in the 280-pin PQFP, 196 user-I/O pads, and 4 embedded array blocks (EABs) each containing 2 Kbits of dual-port RAM for a total of 8 Kbits of on-chip memory. The device supports 5V-tolerant I/O on the 0.35 um process variant and is available in commercial (0C to 70C) and industrial (-40C to +85C) temperature grades. Configuration is via passive serial (PS), passive parallel synchronous (PPS), passive parallel asynchronous (PPA), or JTAG modes using a serial configuration EEPROM such as the EPC2 or EPC8. Architecturally, each Logic Element combines a 4-input LUT, a programmable flip-flop, dedicated carry and cascade chains for arithmetic and wide fan-in functions, and a FastTrack interconnect that delivers constant-delay routing regardless of placement. The four EABs can be configured as 256x8, 512x4, 1024x2, or 2048x1 RAM blocks, or as 4x256 ROM blocks, making the EPF6024AQC280-3 usable for small FIFOs, register files, and lookup-table-based state machines. Typical applications include peripheral bus interfacing (ISA, PCI bridge glue logic), industrial control boards, telecommunications line cards, and legacy system upgrades where the 280-pin PQFP footprint was the de-facto standard. The wide I/O count is particularly useful for memory-controller state machines and parallel data-path bridging. Designers migrating from older FLEX 8000 designs benefit from pin-compatibility planning that allows drop-in upgrade to higher-density FLEX 10K or APEX families. When designing with this part, note that the PQFP-280 package has relatively high thermal resistance and limited I/O drive strength compared to later FineLine BGA packages; account for this in multi-layer board layouts. This page consolidates distributor pricing, lifecycle status, drop-in compatible Altera alternatives from the same FLEX 6000 family, and practical design notes that go beyond the original datasheet.
EPF6024AQC280-3N - 24K Gate FLEX 6000 FPGA | Intel / Altera
The Intel (formerly Altera) EPF6024AQC280-3N is a 24,000-gate member of the FLEX 6000 family of SRAM-based Field-Programmable Gate Arrays, housed in a 280-pin PowerQuad 4 (PQFP) plastic quad flat pack package. It integrates 24,000 typical gates (16,000 logic elements, 1,960 logic cells) with 6,192 RAM bits of embedded memory, four phase-locked loops (PLLs) for clock management, and operates across a commercial 0C to 70C junction temperature range. The -3 speed grade and "N" suffix denote the lead-free, lead-finish designation used by Altera during the FLEX 6000 program. A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable routing interconnect, and configurable I/O cells, all controlled by on-chip SRAM configuration memory. FPGAs sit within the broader programmable logic hierarchy (PLD -> CPLD -> FPGA) and offer the highest logic density and highest performance of any programmable device family. The FLEX 6000 series specifically targets cost-sensitive glue-logic, bus-interface, and state-machine applications where designers need FPGA density but not the highest I/O count of competing families. Key features of the EPF6024AQC280-3N include 235 user I/O pins (the highest I/O count offered in the FLEX 6000 family), 4 PLLs for flexible clock synthesis, multiVolt I/O support (3.3V and 5.0V mixed-voltage operation), in-system programmability through the IEEE 1149.1 JTAG interface, and SRAM-based configuration that allows unlimited reconfigurations. The 280-pin PQFP package uses industry-standard 0.50 mm pitch gull-wing leads compatible with conventional SMT assembly lines. The device is built on a 0.35um CMOS SRAM process with five layers of metal interconnect, which delivers the speed-grade-3 timing closure of approximately 7 ns for a basic look-up table (LUT) operation. The four on-chip PLLs support clock multiplication, division, and phase shifting with sub-nanosecond jitter, simplifying board-level clock-tree design in telecom and industrial-control boards. Typical applications include industrial control and factory-automation controllers, glue-logic replacement around microprocessors and DSPs, telecommunications line cards and protocol bridges, legacy bus-interface adaptors (PCI, ISA, VME), and prototype ASIC emulation. The combination of 24K gates and 235 user I/O makes the EPF6024AQC280-3N a particularly strong fit when designers need to consolidate many discrete 74-series logic chips onto a single programmable device. When designing with this part, allocate configuration memory for the JTAG or EPC configuration device, observe the PowerQuad 4 thermal pad connection to the PCB ground plane, and verify signal-integrity margins on the high-pin-count PQFP package using controlled-impedance routing. The -3 speed grade is the slowest of the FLEX 6000 commercial grades; if a design requires higher fMAX, evaluate the -2 or -1 speed grade. This page synthesizes distributor pricing, drop-in alternatives from the same FLEX 6000 family, and practical design notes that go beyond the manufacturer datasheet to help engineers qualify and source the EPF6024AQC280-3N.
EPF6024AQCAQC240-3 - FLEX 6000 FPGA, 1960 LEs, 240-BFQFP | Altera
The Altera (Intel) EPF6024AQCAQC240-3 is a member of the FLEX 6000 family of Field-Programmable Gate Arrays (FPGAs) housed in a 240-ball Fine-pitch Ball Grid Array (BFQFP) package. Built on a 0.42 µm SRAM-based CMOS process, it integrates 24,000 typical gates (16,000 logic elements, equivalent to 1,960 logic cells / 196 LABs) with 199 user I/O pins, targeting glue-logic and high-volume ASIC-replacement designs. The -3 suffix denotes the speed grade, and the device supports in-system programmability via a standard 8-bit passive serial or parallel configuration interface. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be reconfigured by the customer after manufacturing to implement arbitrary digital logic. FPGAs sit at the top of the programmable logic hierarchy, above CPLDs and below full-custom ASICs. Within Altera's broader product taxonomy, the FLEX 6000 series was a cost-optimized, SRAM-based architecture positioned between the FLEX 8000 and FLEX 10K families, providing register-rich logic for high-density, register-intensive glue logic, datapath, and bus-interface applications. The "E" prefix in EPF6024A indicates an enhanced 5.0V-tolerable I/O variant. Key features include 196 Logic Array Blocks (LABs), each containing 10 Logic Elements (LEs) for a total of 1,960 LEs; 199 maximum user I/O pins; embedded SRAM distributed across the logic fabric; and configurable I/O standards including LVTTL, LVCMOS, PCI, and 5.0V tolerant inputs (with appropriate external limiting resistors). The 240-BFQFP package uses Altera's standard FineLine BGA-style fine-pitch footprint optimized for surface-mount manufacturing. Typical applications include telecommunications line cards, industrial control and factory-automation boards, ASIC-prototyping platforms, and embedded-control systems. The wide I/O count (199) makes it well-suited for bus-bridging applications where multiple legacy peripherals must be aggregated to a modern processor interface. One important design consideration is the 5.0V-tolerance constraint: the EPF6024A's I/O banks are 5.0V-tolerant only with proper external current-limiting, so legacy 5V peripherals may require bus switches or level translators. Additionally, this is a mature/legacy device family; new designs should evaluate Cyclone or MAX families unless second-source supply continuity for an existing platform is required.

EPF6024AQI208-1 - 24K Gate FLEX 6000 PLD, 208-PQFP, 172 MHz | Altera
The Altera EPF6024AQI208-1 is a CMOS loadable Programmable Logic Device (PLD) from the FLEX 6000 family, delivering approximately 24,000 typical gates of user logic in a 208-pin Plastic Quad Flat Pack (PQFP) package with gull-wing leads. It supports a maximum clock frequency of 172 MHz and operates from a 3.0 V to 3.6 V supply with a 3.3 V nominal core voltage, drawing on SRAM-based configuration cells for fast in-system reconfigurability. The device integrates a high-performance Look-Up Table (LUT)-based architecture with embedded FastTrack interconnect and dedicated I/O elements. A Field-Programmable Logic Device (PLD) is a general term that encompasses SPLDs, CPLDs, and FPGAs - all are semiconductor devices whose logic function is defined after manufacturing by the end user. FLEX 6000 sits in the low-density, low-cost tier of the Altera (now Intel Programmable Solutions Group) FPGA portfolio, historically used as a glue-logic replacement for multiple 74-series TTL devices or small PAL/GAL arrays. The 6000 family supports JTAG-based boundary-scan, in-system programmability via the passive serial or ByteBlaster interface, and integrates distributed RAM blocks that can be repurposed as shift registers or small FIFOs. Key features of the EPF6024AQI208-1 include 24 typical logic elements (LEs) per logic array block, four dedicated FastRow/FastColumn interconnect lines, multi-voltage I/O support (3.3 V LVTTL/LVCMOS), and an operating junction temperature range suited for industrial environments. The 208-pin PQFP provides 158 usable I/O pins, sufficient for parallel bus bridging, address decoding, and state-machine intensive control functions. The device uses a 5V-tolerant I/O structure on input buffers, allowing mixed-voltage interfacing with legacy 5 V logic. Embedded JTAG (IEEE 1149.1) and embedded signal-probe circuitry allow post-layout debugging without external logic analyzers. Configuration is volatile and must be reloaded on power-up from a serial PROM or microcontroller. Typical applications include bus-bridge glue logic between microprocessors and peripherals, peripheral controllers in industrial PCs, custom state-machine controllers, address-decoding logic in embedded systems, and prototyping of larger FPGA designs before migration to higher-density families such as Cyclone or MAX. With its 172 MHz performance and 208-pin footprint, the EPF6024AQI208-1 is well-suited to designs where a small, deterministic, low-power PLD is preferred over a full FPGA. When designing with this part, ensure that configuration memory is loaded on every power-up because the SRAM cells are volatile. Plan PCB routing for the 208-pin PQFP with adequate power and ground planes, and verify JTAG chain continuity before relying on in-system updates.
EPF6024AQI208-1N - FLEX 6000 24K FPGA 208-PQFP | Altera
The Intel (Altera) EPF6024AQI208-1N is a member of the FLEX 6000 family of SRAM-based, loadable programmable logic devices, delivering up to 24,000 typical gates (16,000 usable gates) in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) surface-mount package. It is supplied from a 3.0 V to 3.6 V rail with 3.3 V nominal VCC, supports industrial operating temperatures, and reaches maximum internal clock frequencies around 172 MHz in the -1 speed grade. A Field-Programmable Gate Array (FPGA) is a programmable logic device (PLD) that combines thousands of configurable logic elements (LEs), embedded memory blocks, and programmable interconnect into a single semiconductor die. FPGAs sit at the top of the programmable logic hierarchy (PLD -> CPLD -> FPGA -> SoC FPGA) and are used as glue logic, accelerator fabric, and prototyping platforms between discrete 74-series logic and full custom ASICs. The FLEX 6000 family targets cost-sensitive glue-logic, bus-interface, and control-plane applications where small gate counts and 5.0 V-tolerant I/O previously dominated. Key features of the EPF6024AQI208-1N include 1,960 logic elements (LEs), a 4,608-bit embedded SRAM, 171 user I/O pins, and four phase-locked loops (PLLs) for on-chip clock synthesis. The -1 industrial speed grade is offered in a -40 C to +85 C temperature range with 208 gull-wing PQFP leads on a 28 mm x 28 mm body. The device is built on a 0.42 um CMOS SRAM process and is configured via a serial configuration EPROM at power-up. Architecturally, FLEX 6000 devices use a row-and-column LAB (Logic Array Block) structure with continuous FastTrack interconnect that routes signals horizontally and vertically at every LE. This fabric provides predictable timing for synchronous state machines, FIFO controllers, and bus-bridge logic. The four embedded PLLs support clock multiplication, division, and phase shifting across the 171 I/O, simplifying designs that require multiple clock domains from a single reference oscillator. Typical applications include industrial control and factory automation backplanes, telecommunications interface cards, legacy PCI/ISA bus bridges, military and aerospace upgrade programs, and educational FPGA lab kits. The wide-package 208 PQFP footprint makes the EPF6024AQI208-1N particularly attractive for redesigns of older PLCC-84 systems that need more I/O and embedded memory without moving to BGA. When designing with this device, allocate sufficient PCB area for the 28 mm x 28 mm PQFP body and use a 4-layer board with a dedicated VCC plane. Decoupling requires at least one 0.1 uF ceramic per VCC pin plus a single 33 uF tantalum bulk capacitor within 25 mm of the package. Boundary-scan (JTAG) and a ByteBlaster or MasterBlaster download cable are supported for in-system programming through the dedicated nCONFIG, nSTATUS, CONF_DONE and DCLK pins.

EPF6024AQI208-2 - FLEX 6000 PLD 24K Gates 208-PQFP | Altera
The Altera (now Intel) EPF6024AQI208-2 is a loadable Programmable Logic Device (PLD) from the FLEX 6000 family, fabricated on a CMOS process and packaged in a 208-pin Plastic Quad Flat Pack (PQFP, code QFP208,1.2SQ,20) with 0.500 mm terminal pitch. It delivers 24,000 usable gates, 1,960 logic elements (LEs), and 171 configurable I/O lines plus 4 dedicated inputs, organized as 171 inputs and 171 outputs for high-density glue-logic integration. What is a PLD? A Programmable Logic Device is a generic term for a digital IC whose logic function and interconnect are defined after manufacture by the end user. PLDs sit within the broader taxonomy of programmable logic: simple PLD (SPLD, e.g. PAL/GAL) -> complex PLD (CPLD) -> field-programmable gate array (FPGA), with FPGAs occupying the highest density tier. The FLEX 6000 series occupies the CPLD/early-FPGA boundary, optimized for high I/O count and predictable timing rather than register-rich datapath synthesis. Key features of the EPF6024AQI208-2 include a maximum clock frequency of 153 MHz, in-system programmability via SRAM configuration cells (requiring a configuration device on power-up), 5 V tolerant I/O (the 'I' speed grade), and an industrial operating temperature range of -40 C to +85 C. Embedded array blocks (EABs) provide on-chip ROM/RAM for look-up tables and small FIFOs, while each logic element contains a 4-input look-up table and a programmable flip-flop. Architecturally the FLEX 6000 uses a continuous-routing FastTrack interconnect that delivers predictable, compiler-driven delay rather than the segmented routing of later FPGA families. This makes timing closure straightforward at the cost of slightly higher propagation delay per gate compared with Look-Up-Table FPGAs of the same vintage. The PQFP-208 footprint offers through-hole-compatible hand-solderability for prototype and legacy repair, in contrast with the BGA-only options of later Cyclone families. Typical applications include industrial glue logic replacement, bus-interface bridges (e.g. PCI/ISA to local microcontroller), motor-control state machines, legacy telecom backplane glue, and instrumentation front-ends where 5 V I/O tolerance simplifies interfacing to analog front ends. The high I/O count (171 user I/O plus 4 dedicated inputs) suits designs that previously required multiple 84-pin PLDs. When designing with this part, note that FLEX 6000 devices are SRAM-based and lose configuration on power-down; pair with an Altera EPC configuration PROM (EPC1441/EPC1) for non-volatile boot. The PQFP-208 package requires a 1.2 mm pitch PCB footprint with a 30.6 mm body and exposed lead fingers - allocate at least four PCB layers for clean power and ground return paths beneath the package.

EPF6024AQI208-2N - FLEX 6000 24K Gate FPGA, PQFP-208 | Altera
The Altera EPF6024AQI208-2N is a member of the FLEX 6000 family of CMOS SRAM-based programmable logic devices (PLDs), featuring 24,000 typical gates, 1,960 logic elements, and 171 user I/O pins in a 208-pin Plastic Quad Flat Pack (PQFP) package. Per the Altera FLEX 6000 datasheet, the device operates from a 3.3 V core supply with a maximum clock frequency of 153 MHz, and uses SRAM configuration cells that must be loaded at every power-up from an external serial or parallel memory device. A FLEX 6000 device is a fine-grained reprogrammable logic IC that sits between a complex programmable logic device (CPLD) and a high-density field-programmable gate array (FPGA) in the broader programmable logic hierarchy (CPLD -> FLEX 6000 -> FPGA -> SoC FPGA). The FLEX 6000 family was Altera's first Optically reprogrammable, low-cost, SRAM-based FPGA line optimized for high I/O count glue logic and data-path applications. Compared with CPLDs, the FLEX 6000 offers higher register density and richer routing; compared with modern FPGAs, it provides simpler development but lower logic capacity. The EPF6024AQI208-2N delivers 171 configurable I/O lines plus 4 dedicated inputs, supporting a wide range of I/O standards including 3.3 V LVCMOS/LVTTL on the I/O banks. The maximum toggle performance of 153 MHz makes it suitable for mid-speed peripheral controllers, bus bridges, and state-machine replacement. Its high I/O count relative to its logic capacity makes it ideal for I/O-intensive glue-logic designs rather than DSP-heavy workloads. Internally, the FLEX 6000 architecture combines Look-Up Tables (LUTs) for combinational logic with dedicated register cells, interconnected by a continuous FastTrack routing matrix. The device uses SRAM configuration cells, meaning configuration is volatile and must be reloaded from external non-volatile memory (typically an EPC configuration EPROM) on every power-up via the Altera passive serial (PS) or passive parallel asynchronous (PPA) configuration scheme. Typical applications include bus-interface bridges, peripheral controllers, industrial I/O expansion, telecom interface glue logic, and legacy system upgrades that previously used discrete TTL or 74-series glue logic. The 208-pin PQFP package provides a fine-pitch (0.5 mm) surface-mount footprint with gull-wing leads, simplifying PCB assembly on standard reflow profiles. When designing with the EPF6024AQI208-2N, ensure a stable 3.3 V core supply with proper decoupling, and always pair the FPGA with a configuration memory (EPC2, EPC4, or compatible). JTAG boundary-scan is supported via the 4-wire IEEE 1149.1 interface, enabling in-system programming (ISP) and post-assembly verification. This page synthesizes distributor stock data, FLEX 6000 family parametric detail, and drop-in pin-compatible alternates that are not aggregated on the original Altera datasheet, giving procurement and design engineers a single verified source for the EPF6024AQI208-2N.
EPF6024AQI208-3 - FLEX 6000 FPGA 24K Gates 208-PQFP | Intel
The Intel EPF6024AQI208-3 is a member of the FLEX 6000 family of Field Programmable Gate Arrays, integrating 24,000 gates and 1,960 logic cells in a 208-pin Plastic Quad Flat Pack (PQFP) package. Built on a 0.42 µm CMOS process and operating at 3.3 V core, the device provides 171 user I/O pins and is rated for commercial temperature operation, delivering up to 142.86 MHz internal performance. The FLEX 6000 family was engineered as an ideal low-cost, programmable alternative to high-volume gate-array applications and allows rapid design changes during prototyping or design testing. A Field-Programmable Gate Array (FPGA) is a reconfigurable integrated circuit whose logic resources, interconnect, and I/O cells are defined by a user-supplied bitstream after manufacture. FPGAs sit between fixed-function Application-Specific Integrated Circuits (ASICs) and software-driven microcontrollers in the digital design hierarchy: they offer hardware-timed parallelism and deterministic latency unavailable in sequential processors, while avoiding the NRE mask costs of ASICs. The FLEX 6000 series belongs to the broader Programmable Logic Device (PLD) family, which also includes CPLDs and SPLDs. Key features of the EPF6024AQI208-3 include a register-rich, Look-Up Table (LUT)-based logic architecture, OptiFLEX interconnect that minimizes die area for high logic utilization, four Embedded Array Blocks (EABs) for on-chip memory implementation, and built-in JTAG boundary-scan test support (IEEE Std 1149.1). Each logic element (LE) contains a 4-input LUT, a programmable register, and carry/chain interconnect, allowing efficient implementation of arithmetic, register-intensive, and combinatorial designs without external memory components. Architecturally, the device employs a continuous, row-and-column interconnect backbone (FastTrack) that routes signals across the die with predictable delay. The 3.3 V supply rail reduces power consumption by roughly 40 percent compared with the 5.0 V FLEX 8000 predecessors, while still supporting 5.0 V tolerant I/O through clamping diodes on input pins. Configuration can be performed via passive serial, active serial, or JTAG modes using industry-standard EPC configuration devices, enabling in-system reconfiguration for field upgrades. Typical applications span glue-logic consolidation in industrial control boards, peripheral bus interfacing (ISA, PCI, VME), high-speed data-pump controllers, DSP pre-/post-processing front-ends, and low-volume prototypes replacing mask-programmed gate arrays. Because FLEX 6000 silicon is mature and broadly second-sourced on the secondary market, the EPF6024AQI208-3 is also frequently specified for long-lifecycle aerospace, defense, and medical systems that were originally designed in the late 1990s. When designing with this part, observe that the 3.3 V core cannot be directly powered from a 5 V rail - a regulator is required. Inputs are 5 V tolerant via clamping diodes but prolonged overdrive can inject latch-up current; series resistors of 200–470 Ω are recommended on signals driven from 5 V logic. Decoupling follows the standard FPGA guideline of one 0.1 µF high-frequency cap per VCC/GND pair plus bulk capacitors of 10–47 µF at each supply pin group. This page aggregates distributor pricing, verified drop-in alternatives within the FLEX 6000 family, and practical design guidance not consolidated in the original datasheet, supporting both new designs and maintenance of long-life legacy systems.
EPF6024AQI208-3N - FLEX 6000 FPGA 24K Gates | Altera
The Altera EPF6024AQI208-3N is a member of the FLEX 6000 family of Field Programmable Gate Arrays, delivering 24,000 gates, 1,960 logic elements (cells), and a maximum internal operating frequency of 142.86 MHz in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) package. Manufactured on a 0.42 µm CMOS process with a 3.3 V core supply, the device combines a register-rich, look-up-table (LUT) based OptiFLEX architecture with 171 user I/O pins, making it suited for high-volume gate array replacement and rapid prototyping flows. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows engineers to implement arbitrary digital logic via a configurable array of logic blocks, routing channels, and I/O cells. Within the broader taxonomy, the FLEX 6000 sits as a low-cost, register-rich mid-density FPGA, positioned between simple CPLDs and higher-density SRAM-based FPGAs such as the FLEX 10K and APEX families. The FLEX 6000 family was specifically architected as an ideal low-cost programmable alternative to high-volume gate array applications, enabling fast design changes during prototyping and design testing. Key features include the OptiFLEX architecture for high utilization, multiVolt I/O support for interfacing with 2.5 V, 3.3 V, and 5 V buses, in-system programmability through a dedicated configuration interface, and JTAG boundary-scan test support per IEEE 1149.1. The "3N" speed grade designation places this part in a specific performance bin optimized for typical commercial industrial temperature ranges. With 1,960 logic elements and abundant user I/O, the EPF6024AQI208-3N delivers substantial logic capacity for glue logic, bus bridging, and parallel DSP pre/post-processing tasks. From an architectural perspective, the FLEX 6000 family employs continuous, segmented routing interconnect combined with dedicated carry chains and cascade chains that accelerate arithmetic and wide datapath operations. The 0.42 µm four-metal-layer CMOS process delivers a balance of die density, static power, and 3.3 V tolerance that was industry-leading at product introduction. Typical applications include industrial control glue logic, telecommunications interface bridging, prototyping of ASIC designs, parallel peripheral controllers, and embedded system bus arbiters. The 208-pin PQFP package and 171 user I/O pins enable direct interfacing with wide parallel buses such as PCI, ISA, and external memory buses. When designing with this device, pay close attention to configuration mode selection and the configuration device interface, since the FLEX 6000 family supports both passive serial and passive parallel configuration schemes with EPC configuration memories. Designers should also verify supply decoupling on every VCCINT and VCCIO pin per the FLEX 6000 Device Family datasheet recommendations.

EPF6024AQI208-4 - FLEX 6000 FPGA 24K Gates 208-PQFP | Altera
The Altera (formerly Altera, now part of Intel) EPF6024AQI208-4 is a member of the FLEX 6000 family of Field-Programmable Gate Array (FPGA) devices, providing approximately 24,000 logic gates in a 208-pin Plastic Quad Flat Pack (PQFP) package. It is built on a CMOS SRAM process and offers 1960 logic elements (LEs) with 171 configurable I/O pins and 4 dedicated inputs, targeting glue-logic, bus-interface, and peripheral bridging applications that were mainstream in the late 1990s and early 2000s. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs) connected via programmable interconnect, allowing designers to implement custom digital circuits after manufacturing. FPGAs sit in the taxonomy as: PLD -> programmable logic -> FPGA -> SRAM-based FPGA -> FLEX 6000 family. Compared to CPLDs, FPGAs offer higher logic density and richer register-rich architectures but lose non-volatility, requiring an external configuration memory (typically an EPC2 or similar serial PROM). Key features include 1960 logic elements organized as logic array blocks (LABs), embedded memory blocks, and a maximum clock frequency of 153 MHz. The device supports in-system programming via the FLEX 6000 configuration scheme, supports JTAG boundary-scan testing, and provides tri-state bus-friendly I/O with individually programmable slew-rate and drive-strength control per pin. The FLEX 6000 architecture employs a four-input LUT-based logic element, FastTrack interconnect for predictable timing, and a continuous routing structure that simplifies place-and-route. Configuration bitstream loads from a serial EPROM or microprocessor interface, and the device supports passive parallel, passive serial, and JTAG configuration modes. Typical applications include PCI bridge logic, legacy peripheral controllers, telecom line-card glue logic, industrial control boards, and replacement of discrete 74-series TTL/MSI gate arrays in long-lifecycle systems. The wide 171 I/O count suits bus-intensive designs. When designing with this FPGA, ensure configuration storage is provisioned and verify the speed grade (-4) matches timing closure requirements for the target logic. The -4 speed grade is one of the slower grades; newer logic designs should be verified against timing analysis.

EPF6024AQI208-4N - 24K Gate FLEX 6000 FPGA 208-PQFP | Intel (Altera)
The Intel (formerly Altera) EPF6024AQI208-4N is a member of the FLEX 6000 family of SRAM-based programmable logic devices, providing 24,000 typical gates (equivalent logic elements) in a 208-pin Power Quad Flat Pack (PQFP) package. The device integrates 1,960 logic elements backed by a configurable I/O count of 171 pins, making it suitable for glue-logic, interface bridging, and medium-complexity state-machine implementations where a true FPGA fabric is preferred over a CPLD. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit that can be electrically configured by the customer after manufacture to implement arbitrary digital logic. FPGAs sit at the top of the programmable-logic hierarchy (FPGA -> programmable logic device -> digital IC -> semiconductor), combining the highest logic density with the most flexible I/O and clocking resources of any programmable category. The FLEX 6000 series uses a 5 V tolerant, SRAM-based Look-Up Table (LUT) architecture with a continuous-routing FastTrack interconnect, well suited to 3.3 V core designs of the late 1990s and early 2000s. Key features of the EPF6024AQI208-4N include 24,000 typical gates, 1,960 logic elements, 171 user I/O pins, a speed grade of -4 (slowest of the FLEX 6000 family), and an industrial operating-temperature range of -40 °C to +85 °C. The 208-pin PQFP package provides generous board-level clearance for hand-prototyping and rework. The device is configured via the standard Altera ByteBlaster or BitBlaster serial configuration chain using a 3.3 V or 5 V configuration EPROM companion. Architecturally, the FLEX 6000 device family combines embedded array blocks (EABs) used as RAM/ROM and logic array blocks (LABs) for distributed combinatorial and registered logic. Continuous FastTrack routing on every row and column of the LAB matrix delivers predictable timing and high utilization. Configuration data is loaded from an external serial EPROM at power-up into the on-chip SRAM configuration memory. Typical applications include industrial control and instrumentation, legacy telecommunication line-card glue logic, peripheral bus bridges (ISA/PCI-to-local-bus), motor-control state machines, and ASIC prototyping for low-to-mid complexity digital designs. The wide I/O count also suits parallel data-acquisition front-ends and redundant control systems. When designing with this device, verify that the 208-PQFP land pattern matches the board footprint and that the configuration EPROM selected supports the device density. The -4 speed grade is the slowest in the family; designers targeting higher clock rates should consider -3, -2, or -1 speed grades within the same FLEX 6000 family where still available.

Built on SRAM-based OptiFLEX architecture, the device provides a low-cost alternative to gate-array designs while maintaining high performance and routability, with reconfigurable SRAM elements allowing in-system design changes without board rework. A Field Programmable Gate Array (FPGA) is a type of integrated circuit containing programmable logic blocks, configurable interconnects, and configurable I/O cells, designed to be configured by the customer or designer after manufacturing. FPGAs sit at the top of the digital logic hierarchy (logic cell -> logic block -> programmable logic device -> FPGA -> programmable logic IC) and serve as a flexible alternative to fixed-function ASICs, particularly suited for low-to-medium-volume production, prototyping, and designs requiring post-deployment updates. Key features of the EPF6024AQI208-7 include 1,960 logic elements, 171 maximum user I/O pins, 196 flipflops, and continuous SRAM-based configuration supporting JTAG-based in-system programmability (ISP). The OptiFLEX architecture combines FastTrack interconnect with localized logic-array blocks (LABs), achieving deterministic timing with typical pin-to-pin delays down to 8 ns at the -7 speed grade. The device operates from a 5.0 V core (VCCINT) with 3.3 V or 5.0 V tolerant I/O banks selectable per pin. Typical applications include glue-logic replacement, interface bridging, bus arbitration, state-machine controllers, and peripheral expansion in industrial control, telecommunications, and embedded computing platforms. The -7 speed grade and industrial temperature range (-40C to +85C) make it suitable for moderate-speed control-plane functions where flexibility and fast time-to-market outweigh raw logic density. When designing with the EPF6024AQI208-7, use the Altera MAX+PLUS II or Quartus design environment for synthesis, place-and-route, and timing analysis. Provide a 5.0 V VCCINT rail with at least 1 uF of bulk decoupling near the supply pins, and ensure all configuration pins (nCONFIG, nSTATUS, CONF_DONE, MSEL) are pulled to the correct logic level for the chosen configuration mode.
