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

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. This page synthesizes distributor pricing from DigiKey and Octopart, FLEX 6000 family pin-compatible drop-in alternatives from the Site MPN list, and practical design notes that complement the official FLEX 6000 datasheet.
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.

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.

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.

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 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.

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 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.

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.

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.

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.

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.
